Section 1

Introduction

On behalf of Lockheed Martin Corporation, Tetra Tech, Inc. (Tetra Tech) has prepared this

Design Report to serve as the basis for implementation of interim remedial measures (IRM) at

the Tax Block E storm drain system at the Middle River Complex (MRC) in Middle River,

Maryland. The IRM work will consist of removing contaminated sediment and debris from the

drainage system and associated inlets and manholes, providing interim sediment controls,

repairing or replacing inlets and manholes, as necessary, and abandoning storm drain lines, inlets

and manholes that are no longer serviceable. The purpose of the IRM is to minimize the transport

of contaminated sediments in the storm drain system to off-site locations and to allow clear

drainage of the Block E area. The IRM is an initial step in a more comprehensive remedial

activity planned for Block E for contaminated sediments in Dark Head Cove.

This Design Report, along with its associated design plans (Appendix B), technical specifications

(Appendix C), and construction work plans (Appendices D–I), comprise the complete package of

documentation necessary to implement the IRM for the Block E storm drain system. The

construction work plans include a “Construction Quality Control Plan,” “Site and Temporary

Facilities Plan,” “Site-Specific Hazardous Materials Health and Safety Plan,” “Waste

Management Plan and Addendum # 1,” “Environmental Protection and Erosion Control Plan,”

“Construction Methodology Plan,” and “Project Schedule.” The design plans and technical

specifications detail the civil and structural work associated with the inlet/manhole/structure

repairs and describe how sediments will be removed from storm drain pipes, as well as detailing

project controls. The construction work plans describe the methods for managing the

contaminated sediments that will be removed as part of the IRM.

This Design Report is organized as follows:

Section 2—Site Background: Describes the components of the Block E storm drain system

and summarizes the findings of the June 2009 investigation of the drainage system


Section 3—IRM Implementation Methodology: Describes the methodology for implementing the IRM, including construction work plans, preparation activities, field methods, waste management, and site restoration

Section 4—Notification and Regulatory Requirements: Identifies applicable notification and regulatory requirements and approvals

Section 5—Project Schedule: Presents a preliminary project schedule

Section 6—Estimated Costs: Provides estimated costs for IRM implementation and annual maintenance of the sediment controls placed at inlets

Section 7—References: Cites references used in this report


Section 2

Site Background

2.1 STORM DRAIN COMPONENTS

The current Block E storm drain system (Figure 2-1) consists of groups of surface water inlets

(IL) or grated drains, catch basins, manholes (MH), and underground pipes that discharge to

Dark Head Cove via three outfalls: Outfall 05, Outfall 06, and Outfall 08. These outfalls are in

the southern and eastern portions of Block E (Figure 2-2). A pre-sampling site reconnaissance in

2009 identified 34 existing inlets and manholes that drain Block E1. The Block E storm drain

system outfalls and other components are described below, grouped as three separate systems for

clarity; however, the systems are interconnected.

Outfall 05 system—The Outfall 05 storm water system (Figure 2-3) is constructed of rectangular

brick and mortar inlet boxes with steel-grate covers, brick and mortar manholes with solid

covers, and circular concrete pipe. Pipe sizes for the system range from 15-inches in diameter at

upstream inlets IL-19 and IL-20 to 32-inches in diameter at downstream manholes MH-3, MH-2,

and MH-1. Outfall 05 has two discharge points that drain surface water in the southern portion of

Block E via a series of inlets beginning at upstream inlet IL-20. Storm water flows westward to

IL-19, where the system splits, with one pipe going to MH-7, MH7a, and MH-4, and the other

pipe running to IL-18. The system reconnects and continues as one pipe southwest below

Chesapeake Park Plaza (with surface features IL-30 and MH-3), where it splits and runs to MH-2

and MH-1 and discharges to Dark Head Cove via the two Outfall 05 discharge points.

A western extension of the system starts at inlet IL-17 and connects to MH-4. This pipe is

reported to be 12-inch diameter concrete, but this could not be verified during the 2009 field

activities due to sediment and deep standing water above the crown of the outlet pipe at IL-17.

Three additional extensions are shown on historical maps: (1) a 24-inch diameter reinforced

1Six additional inlets and manholes comprise a storm water system east of Block E (Outfall 09).


concrete pipe (RCP) extending north from MH-4; (2) a 24-inch diameter RCP line extending

west from IL-18; and (3) a 15-inch diameter RCP line extending north and east from IL-20. The

presence of these extensions was not confirmed due to system conditions during the June 2009

survey (see Table 3-1).

Outfall 06 system—The Outfall 06 storm water system (Figures 2-4 and 2-5) is constructed of

rectangular, brick and mortar inlet boxes with steel grate covers, brick and mortar manholes with

solid covers, and circular concrete pipe, except for corrugated steel pipes connecting IL-10 and

IL-11 and IL-11 to IL-21. Pipe sizes for the system range from 12-inches in diameter at upstream

inlets IL-10 and IL-11 to 32-inches in diameter at downstream inlet IL-25 to Outfall 06. This

system drains surface water in the northern portion of Block E via a series of inlets beginning at

upstream inlet IL-16 in the north-central portion of Block E. Storm water flows eastward to inlet

IL-22, where the system continues south below the median of Chesapeake Park Plaza at IL-9,

IL-24, and IL-25, and discharges to Dark Head Cove at Outfall 06. This part of the system also

receives local storm water from the northeast corner of Block E at inlets IL-10, IL-11, and IL-21.

Outfall 08 system—The Outfall 08 storm water system (Figure 2-4) is constructed of rectangular,

brick and mortar inlet boxes with steel grate covers, brick and mortar manholes with solid

covers, buried manholes, and circular concrete pipe. Pipe sizes for the system range from

12-inches in diameter at upstream manhole MH-7 to 24-inches in diameter from IL-1 to

Outfall 08. The Outfall 08 system runs north-south and drains surface water in the eastern

portion of Block E drains via a series of inlets/pipes beginning at upstream inlet IL-7 in the

east-central portion of Block E. Storm water flows southward to MH-10 (IL-3) then to IL-2 and

IL-1. Storm water discharges to Dark Head Cove at Outfall 08. Inlet IL-23 is connected to both

IL-4 and IL-24. Storm water entering into IL-23 may discharge to both Outfalls 06 and 08.

MH-10 (IL-3) is also connected to the storm system line to the west at MH-9, MH-8 and MH-7.

Storm water has been observed flowing in the pipe entering MH-10 (IL-3) from the west. MH-8

and MH-9 are buried below grade and are not visible at the ground surface.


2.2 STORM DRAIN INVESTIGATION (JUNE 2009)

In June 2009, Tetra Tech surveyed storm drain condition and collected storm drain sediment

samples. The survey inspected and documented the condition of the Block E storm drain system,

and assessed the potential for contaminated groundwater to infiltrate the pipeline and be

conveyed to the outfalls. Sediment samples were collected from storm drain inlets and manholes

for chemical analyses to evaluate the presence and distribution of possible contaminants. The

findings, results, and recommendations are detailed in the Block E Supplemental Soil and Storm

Drain Sediment Characterization Report prepared by Tetra Tech in November 2009. Select

excerpts (i.e., tables and figures) are included in Appendix A. A summary is provided in the

following sections.

2.2.1 Storm Drain Condition Survey

The storm drain condition survey was conducted June 11–15, 2009 by TRB Specialty

Rehabilitation, Inc. of Gambrills, Maryland. The survey used robotic video equipment. Audio

notations were made regarding the presence of sediment, locations of cracks or damage,

manholes, joint separation, percentage of obstruction, infiltrating groundwater, or other

significant observations. Thirty video logs were recorded for lines associated with

Outfalls 05, 06, 08, and 09. Videos were terminated upon the approach to the outfalls due to deep

water or mud. Several lines could not be inspected due to collapsed inlets, backfilled manholes,

in-line obstructions (e.g., sediment or rocks), or flooded pipes. The results of the condition

survey are summarized below and tabulated in Table 4-1 of Appendix A.

Outfall 05—Inspections of inlets IL-19 and IL-20 indicate partial inlet-box collapse at both

inlets and continuous coarse sediment in the 18-inch diameter concrete pipe. The portion of pipe

surveyed (0.0–5.5 feet downstream from IL-20) was in good condition, with no cracking or

leaks. However, the survey was terminated at 5.5 feet downstream of IL-20 due to an obstruction

in the line (i.e., concrete block). Manholes MH-1, MH-2, and MH-3 contained several inches of

soft mud which prevented the use of the camera at these locations. In-line surveys could not be

conducted for IL-17 and the connecting section between inlet IL-18 and MH-3 due to flooded

pipes. Approximately six inches of soft sediment were found at the bottom of IL-17. Manholes

MH-4 and MH-7 were filled with soil/sediment; therefore, surveys could not be conducted at

these locations.


Outfall 06—Inlets and conduits were in good condition in the north-south branch of Outfall 06.

Except for IL-11, all inlets have steel grate covers that were in good condition and free of

obstructions. IL-11 is a 2.5-foot by 2.5-foot brick and concrete box with a concrete cover and

was in good condition. Most inlets contained little or no sediment, except for some brick debris

in IL-10. Small longitudinal cracks were observed at the top of the pipes at several joints in the

main line between inlets IL-9 and IL-25. Incrustation (i.e., mineral accumulations from water

seepage) and groundwater infiltration were also observed at most joints along this portion of the

system. Sediment accumulations were typically present in the five to seven o’clock positions

(i.e., circumferential location) along several stretches of the line viewing downstream between

IL-9 and IL-25. The survey for IL-24 to IL-25 was terminated at 104 feet downstream of IL-24

due to high water. Sediment was also reported in the pipes connecting IL-23 to IL-24 and IL-11

to IL-10. One medium joint separation (less than one inch) was reported at 12.4 feet from IL-23

in the conduit connecting IL-23 and IL-24. Groundwater was not observed infiltrating the

pipeline at this location.

Inlets IL-8, IL-12, IL-14, and IL-16 on the east-west branch of Outfall 06 were in good

condition. IL-12 had brick separation on two end walls due to differential settling. These four

inlets contain little or no sediment, and have steel grate covers that were in good condition and

free of obstructions. Inlets IL-12A, IL-13, and IL-15 did not have grates and their inlet boxes

were partially collapsed and filled with rocks, soil, and trash. However, water was observed

flowing through these inlets during the survey and sampling event. Surveys could not be

conducted at these locations because the pipes were partially blocked by soil and/or debris.

Pipes surveyed from IL-9 to IL-12 were generally in good condition. Incrustations were observed

at several joints along this portion of the system. Sediment accumulations were observed in

piping between IL-8, IL-12A, and IL-12. The survey could not be conducted for the line west of

IL-12 due to flooded pipes, collapsed inlets, and pipe obstructions.

Outfall 08—All inlets along the north-south line (IL-2 to IL-7) have steel grate covers that were

in good condition and free of obstructions. These inlets contained little or no sediment. IL-4 and

IL-6 are small, 13-inch by 13-inch, steel-grated inlets that do not have inlet boxes but feed

directly into the top of the underlying storm drain pipe. Medium joint separations (1–2 inches),

fine root infiltration, and sediment were reported in the main line between MH-10 (IL-3) and


IL-2. Medium joint separations, groundwater infiltration, and sediment were between MH-10

(IL-3) and IL-4. The 15-inch diameter pipe connecting IL-5 to IL-23 was nearly full of sediment,

and gravel, and fines and brick fragments were in the pipes connecting IL-4 to IL-5, IL-5 to IL-6

and IL-6 to IL-7. Joint offsets, a joint separation, and sediment were observed in the 12-inch

diameter pipe from MH-10 (IL-3) to MH-9. However, the survey was terminated at 50.3 feet

west (upstream) of MH-10 (IL-3) due to large rocks completely blocking MH-9. MH-9 was

backfilled with large rocks. MH-9 and MH-8 are buried and have not been located at the ground

surface. The video survey confirms the presence of MH-9, and water at MH-9 was observed

flowing from the west (i.e., from manhole MH-8 direction) through the rocks at MH-9 and

toward MH-10 (IL-3). The location of MH-8 could not be confirmed because of the pipe

blockage at MH-9 and backfilled manholes MH-7 and MH-4.

2.2.2 Storm Drain Sediment Sampling

Sediment samples were collected from 20 storm drain inlets and manholes and one water valve

vault (MH-7A) (shown in Figure 3-2 and summarized in Table 3-2 of Appendix A). Samples

were collected to evaluate the presence and distribution of possible contaminants in the storm

drain sediment. Samples consisted of sediment accumulated at the bottom of storm water inlets

or manholes or soil in the case where the inlet or manhole collapsed. All sediment samples were

analyzed by TestAmerica, Inc. for polychlorinated biphenyls (PCBs) (SW 846, USEPA Method

8082), polycyclic aromatic-hydrocarbons (PAHs) (SW 846, USEPA Method 8270), metals (SW

846, USEPA Method 8010), and volatile organic compounds (VOCs) (SW846, USEPA Method

8260). Six sediment samples were also analyzed for organics/inorganics by means of the

“Toxicity Characteristics Leaching Procedure” (TCLP) and the federal Resource Conservation

and Recovery Act (RCRA) regulated characteristics of ignitability, corrosivity, and reactivity to

assess whether the sediment is hazardous, in accordance with federal and state regulations.

Samples underwent Level IV data-validation procedures in accordance with USEPA Region III

protocols to ensure that the laboratory chemical results are valid and accurate.

A summary of detected concentrations in the sediment samples appears in Appendix A in

Table E-2 and Figures 4-2 and 4-3. The preliminary cleanup goals for sediment chemical(s) of

concern (COC) are 1,000 µg/kg for PCBs, 700 µg/kg for benzo(a)pyrene equivalents (BaPEq),


8 mg/kg for cadmium, and 138 mg/kg for chromium. The BaPEq concentration represents the

combined effects of multiple PAHs detected at the site.

Sampling results confirm the presence of PCBs in nearly all storm drain sediment samples

collected in Block E. The greatest concentrations of total PCBs (total of all detected Aroclors)

are reported for samples collected in the southern portion of the site in the Outfall 05 system. All

total PCB concentrations for the Outfall 05 system exceed the preliminary sediment cleanup

criterion of 1,000 µg/kg, and all Outfall 05 samples except manhole sediment (MHSD) sample 2

(MHSD-2) exceed a concentration of 10,000 µg/kg.

Sampling results also confirm the presence of PAHs in all storm drain sediment samples

collected in Block E. BaPEq concentrations for all but three of the storm drain sediment samples

exceed the preliminary sediment cleanup goal of 700 µg/kg. The greatest concentrations of

BaPEq are for samples collected in the eastern and northeastern portions of the Block E and

upstream of Outfalls 06 and 08. BaPEq concentrations in storm drain sediment range from

332 µg/kg at inlet sediment sample 24 (ILSD-24) (Chesapeake Park Plaza) to a maximum of

139,052 µg/kg at ILSD-4. Concentrations of cadmium in three samples (ILSD-4, ILSD-7 and

ILSD-18) and chromium in one sample (ILSD-4) exceed the preliminary cleanup goals of 8 and

138 mg/kg, respectively. Non-COC metals exceeding sediment-screening criteria are arsenic (11

exceedances), cobalt (seven exceedances), iron (three exceedances), antimony (one exceedance),

lead (one exceedance), manganese (one exceedance) and vanadium (one exceedance).

Low concentrations of VOCs were detected in several sediment samples. Except for sample

ILSD-17, all VOCs were detected at trace to low concentrations that do not exceed sediment-

screening criteria and or indicate sediment-based VOC contaminant sources. The highest VOC

results are reported for chlorobenzene, with concentrations ranging from 0.52 µg/kg at

MHSD-7A to 2,500 µg/kg at MHSD-4. Sediment samples with the greatest number and overall

greatest concentrations of VOCs (primarily benzene isomers) include ILSD-17, MHSD-4, and

ILSD-18 in the Outfall 05 drainage area in the southern portion of Block E. These samples were

followed by MHSD-7 and MHSD-2 in terms of number and concentrations of VOCs.

Many of the VOCs detected in sample ILSD-17 are also reported in samples collected at

downstream locations MHSD-4, ILSD-18, MHSD-2, and MHSD-7. TCE was detected in six


inlet-sediment samples from Outfall 08 (ILSD-4, ILSD-8, ILSD-12, ILSD-14, ILSD-15, and

ILSD-24), with concentrations ranging from 0.58 µg/kg at ILSD-14 to 37 µg/kg at ILSD-8.

Trace to low concentrations of TCE-degradation products (e.g., dichloroethenes, vinyl chloride,

etc.) were typically co-located with these TCE detections. These inlets are near the groundwater

Eastern TCE Plume and indicate that the storm drain system may be a possible pathway for

migration of TCE from groundwater into the storm drain pipe and ultimately to surface water.

TCLP organic and inorganic and RCRA characteristics were analyzed for six of the sediment

samples to determine if the sediment is a RCRA hazardous waste as defined by federal and state

regulations, and to evaluate disposal methods. Samples analyzed for TCLP/RCRA include

locations in Outfall 05 (samples ILSD-18, MHSD-2 and MHSD-4) and Outfall 08 (samples

ILSD-10, ILSD11, and ILSD-24). These locations represent outfalls either containing a large

portion of the sediment that may require removal and off-site disposal (e.g., backfilled manhole

MH-4 or ILSD-24 (which is the end inlet for the sediment-filled pipe between IL-5 and IL-23) or

locations where possibly contaminated or sludge-like sediments were observed (e.g., MHSD-2,

ILSD-11, and ILSD-18). Results of the TCLP and RCRA characteristics analyses indicate that

sediments in the Block E storm drain system are not a RCRA hazardous waste. However, some of

the sediments will be considered PCB-containing wastes and will have to be handled in accordance

with federal Toxic Substances Control Act (TSCA) [40 Code of Federal Regulations (CFR) 761].

2.2.3 Summary of Storm Drain Condition Survey Results

• Storm drain condition was surveyed on June 11–15, 2009 using a rubber-track “crawler” equipped with a video camera. Numerous pipes could not be inspected due to collapsed/obstructed inlet boxes, backfilled manholes, pipe obstructions, or flooded pipes.

• Five inlets are partially collapsed and contain soil, rocks, or other debris that partially obstruct the inlets or inlet pipes

• Two manholes (MH-8 and MH-9) are buried and inaccessible

• Four manholes (MH-4, MH-7, MH-7A, and MH-9) appear to have been abandoned and filled with soil and rocks. MH-9 has been backfilled and partially obstructs flow from the upstream pipe. However, the use of large rocks for backfill allows some water to flow through MH-9 to downstream locations.


• Joint incrustations, groundwater infiltration, and sediment accumulations are common for most pipes. Several sections of large pipes have small longitudinal cracks near joints and root intrusion. Medium pipe offsets were observed in the line connecting MH-10 (IL-3) to MH-9. One small line from IL-5 to IL-23 is nearly full of sediment.

2.2.4 Summary of Storm Drain Sediment Sampling Results

• Sediment samples were collected from 20 storm drain inlets and manholes and one water valve vault from June 10–12, 2009.

• Concentrations of PCBs exceed the Block E preliminary sediment cleanup goal of 1,000 µg/kg at 13 sampling locations. All PCB concentrations for Outfall 05 sediment samples exceed the preliminary cleanup goal.

• All but four sampled concentrations exceed the preliminary sediment cleanup goal of 700 µg/kg for PAHs. The greatest concentrations of PAHs are reported for samples collected in the eastern and northeastern portions of the Block E (samples ILSD-4, ILSD-14 and ILSD-8) upstream of easternmost Outfalls 06 and 08.

• Low concentrations of VOCs were detected in several sediment samples. However, all levels are below sediment-screening criteria, and the reported concentrations do not indicate sediment-based VOC contaminant sources.

• TCE was detected in six inlet-sediment samples from Outfall 08. These inlets are near the groundwater Eastern TCE Plume and indicate that the storm drain system may be a possible pathway for migration of TCE from groundwater to surface water.

• Concentrations of cadmium and chromium exceed preliminary cleanup goals at three locations. Seven other metals in the storm drain sediment samples exceed sediment-screening criteria. However, these concentrations exceed their respective criteria infrequently.

• The results of the TCLP and RCRA characteristics analyses indicate that sediments in the Block E storm drain system will not require handling and disposal as a RCRA hazardous waste. However, PCB concentrations at two locations exceed 50 mg/kg and will require handling under TSCA.

The findings of the storm drain condition survey and sediment sampling results led Tetra Tech

(in the Block E Supplemental Soil and Storm Drain Sediment Characterization Report) to

recommend the following actions for safety and contaminant transport mitigation: (1) fill

depressed areas around collapsed structures; (2) replace missing grates; and (3) remove known

oily accumulation in inlets. These actions and additional cleaning and repair, (or abandonment of

unusable lines) comprise the interim remedial measures to be implemented, as detailed in the

following sections of this Design Report. These actions are not designed to achieve the


preliminary sediment cleanup goals but rather to remove the more mobile sediment that could

migrate off-site from the drainage system.


Section 3

Implementation of Interim Remedial Measures

The Interim Remedial Measures (IRM) work will consist of removing contaminated sediment

(including oily accumulation in inlets) and debris from the Block E storm drain system and

associated inlets and manholes, providing interim erosion and sediment controls, and repairing or

replacing inlets and manholes, as necessary. If inlets, manholes or pipe sections are damaged

beyond repair, those sections of the storm drain system will be removed or plugged and

abandoned in place. The work is referred to herein as “IRM construction”. IRM construction

documentation will consist of this Design Report, design plans (Appendix B), technical

specifications (Appendix C), and construction work plans (Appendices D–I). As indicated in

Section 1, all these documents are necessary for the IRM construction. The design plans and

technical specifications detail the civil/structural work associated with the

inlet/manhole/structure repairs, describe how sediments will be removed from the storm drain

pipes, and describe project controls that will be used. The construction work plans describe the

methods for managing the contaminated sediments to be removed as part of the IRM; the

construction work plans are briefly described below.

3.1 CONSTRUCTION WORK PLANS AND REPORTS

The following work plans guide the IRM activities:

• “Construction Schedule” (before mobilization)—A preliminary schedule (Appendix D) has been developed using Microsoft Project 2007® and is discussed in section 5. The schedule includes a “Critical Path Network” to successfully complete the work within the allotted time. The schedule will be updated during the 90% design package and final (100%) construction documents phases. After mobilization for implementation of the interim remedial measures, the schedule will be revised as needed, with notification of Lockheed Martin.


• “Construction Quality Control (CQC) Plan”—This plan (Appendix E) serves as guidance throughout the life of the project. The CQC plan presents the approach for confirming that the interim remedial measures have been achieved for a specific location.

• “Site and Temporary Facilities Plan”—This plan (Appendix F) details the construction staging and storage areas, decontamination facilities, wash water and sediment collection facilities, and any other temporary facilities the work requires.

• “Site-Specific Hazardous Materials Health and Safety Plan (HASP)”—This plan (Appendix G) addresses all aspects of the project, including site access control, emergency response, and hazard communications. The site-specific health and safety plan includes emergency response procedures; therefore, a separate emergency response plan has not been prepared.

• “Waste Management Plan”—Tetra Tech prepared an addendum (“Addendum #1;” see Appendix H) to the existing waste management plan (WMP) for the site detailing procedures for waste profiling, transportation, and disposal.

• “Environmental Protection and Erosion Control Plan”—This plan (Appendix I) describes how Tetra Tech complies with applicable federal, state and local environmental regulations.

• “Construction Methodology Plan”—This plan (Appendix J) describes the means, methods, and sequences for removing sediment and debris from the drainpipes, inlets, and manholes, as well as other work required to implement the interim remedial measures.

After completion of the fieldwork, Tetra Tech will prepare a Final Site Remediation Report:

• Final Site Remediation Report—This report will document completed work in compliance with regulatory standards, including documentation of transportation and off-site disposal of contaminated material with supporting analytical data. The Final Site Remediation Report will include a record of topographic and physical features and a survey of all disturbed areas conducted by a Maryland-licensed land surveyor to document that the site has been restored to a condition as close as practical to its original pre-construction state. The survey will include an as-built drawing for any repaired and/or replaced inlets and manholes. The Final Site Remediation Report will also include the results of a post-cleaning video survey of selected portions of the Block E drainage pipes.

3.2 FAILURE-MODE EFFECTS-ANALYSIS

A failure-mode effects-analysis (FMEA) was completed before finalization of the project

documentation (Design Report, plans, specifications, and construction work plans) so that

actions recommended by the FMEA have been addressed in these documents. Following

approval of the final (100%) construction documents and work plans, Tetra Tech will complete


the following tasks in preparation for IRM construction. These tasks are discussed in more detail

in subsequent sections:

• Compliance with existing permits, obtaining any other permits/approvals necessary for completion of the IRM, and providing applicable notifications

• Selecting subcontractors, coordinating site access, conducting a pre-construction walkthrough with subcontractors, and reviewing health and safety requirements

• A pre-construction survey of site features and elevations

• Mobilization activities

• Obtaining utility clearance in the proposed work locations using a private firm

• Implementing the “Site and Temporary Facilities Plan” by constructing/providing the temporary support facilities needed to perform the IRM

• Implementing the environmental protection and erosion control plan by establishing erosion control measures to minimize transport of suspended solids, turbidity, and other materials that could degrade water quality

3.3 SITE PREPARATION AND FIELD METHODOLOGY

3.3.1 Permits and Notifications

Tetra Tech will comply with existing permits obtained by Lockheed Martin, obtain any other

permits/approvals necessary for completion of the IRM, and provide notification of work

initiation to Baltimore County, the Maryland Department of the Environment (MDE), and the

United States Environmental Protection Agency (USEPA), as specified in Section 4. Tetra Tech

is currently in communication with Baltimore County to obtain approval to discharge the

wastewater from the IRM construction to the sanitary sewer. If approval is granted, Tetra Tech

will comply with the notification and other requirements required by Baltimore County. Our

conversations with Baltimore County staff indicate that no additional permits will be needed.

3.3.2 Site Access

All field personnel will receive site-specific safety training from the Lockheed Martin facility

maintenance contractor. Subsequent to being trained, these personnel will be issued a security

pass to access the site. Tetra Tech will coordinate with Lockheed Martin to gain access to the

work area around Block E. Main access will be through the Gate A security checkpoint. For more


efficient and less disruptive access, Tetra Tech will request to access Block E through Gate D.

Access to the outfalls will require access through the boat ramp gate.

3.3.3 Health and Safety Requirements

Before field operations, Tetra Tech personnel and subcontractors will become familiar with the

site-specific HASP (Appendix G) and the respective “Safe Work” permits included in the HASP.

Tetra Tech will conduct mandatory health and safety tailgate meetings before each day’s field

activities. Subcontractors present for that day’s field activities will be included in these meetings.

The on-site supervisor (OSS) will document pertinent topics discussed and personnel in

attendance. A Tetra Tech engineer or scientist will serve as the OSS, with support from other

Tetra Tech staff, and provide full-time oversight of any subcontractors working on the IRM

construction.

Site preparation and IRM construction will be completed by a hazardous waste operations

(HAZWOPER)-trained crew using Level C or modified Level D personal protective equipment

(PPE), as appropriate. All IRM work will be done from above ground except in those instances

where access to a drainage pipe is limited and entry to a confined space is necessary. In such

instances, structures will be entered in accordance with federal Occupational Safety and Health

Administration (OSHA) procedures for confined space entry.

Air will be monitored during IRM construction; however, removing sediment from the pipes is a

wet operation whereby the sediments/water are vacuumed from the pipes and stored in metal

containers, so dust from this operation is not anticipated. Further, inlet/manhole repairs are very

small areas (a few square feet), so vacuuming and/or handwork being done and dust being

generated beyond the immediate manhole area is not anticipated. Nevertheless, work at a

manhole/inlet for sediment removal/repairs will have three dust monitors (one upwind and two

downwind) in the work area perimeter.

Dust monitors measure real-time concentrations of airborne particulates within a range of 0.01–100

milligrams per cubic meter (mg/m3). In addition to monitoring dust concentrations, visual

observations will determine if a corrective measure needs to be put in place. Airborne dust

concentrations become visible at a concentration of approximately 2.5 mg/m3 (this level is

conservative for PCBs and other site COC). Corrective measures for dust mitigation will be


incorporated in the unlikely event that dust concentrations exceed 2.5 mg/m3. Monitoring results

will be checked periodically each day and summarized in the final report.

A radiation survey meter capable of detecting alpha, beta, and gamma radiation will be used to

screen sediment during collection. Detection of radiation above background will result in a

temporary work stoppage and evaluation of further action.

3.3.4 Mobilization/Demobilization

Tetra Tech will procure the required subcontractors and begin mobilization. The OSS will

coordinate the mobilization/demobilization activities. These activities include implementing the

Site and Temporary Facilities Plan. Mobilization/demobilization will include the following:

• Coordinate with Lockheed Martin MRC personnel

• Mobilize subcontractors, equipment, and materials to the site

• Implement the site-specific health and safety plan (HASP)

• Implement the “Site and Temporary Facilities Plan”

• Implement the “Environmental Protection and Erosion Control Plan”

• Demobilize equipment and materials from the site (at work completion)

• General site clean-up and trash removal (at work completion)

• Repair landscape and ground surface as necessary (at work completion)

• Manage wastes (sediment, debris, and wastewater)

3.3.5 Pre- and Post-Construction Land Surveys

Tetra Tech will retain a Maryland-licensed land surveyor to conduct a pre-construction survey to

record topographic and as-built features of the planned and potential areas of disturbance around

the Block E storm drain system using the Maryland Coordinate System (based on NAD83). Tetra

Tech will minimize disturbance areas to only work areas, to the extent practicable. Following

completion of all fieldwork, a post-construction survey will document that the site has been

restored to a condition as close as practical to its original pre-construction state. The

post-construction survey will include an as-built drawing for elevations of any repaired and/or

replaced inlets and manholes.


3.3.6 Utility Clearance

Tetra Tech will notify the underground-utility location center (Miss Utility of Maryland

[1-800-257-7777; www.missutility.net]), review facility maps containing utility information

(including the Site Utility Plan [Tetra Tech, June 30, 2010]), and use a private utility-locating

contractor, where excavation is necessary.

3.3.7 Temporary Support Facilities

Tetra Tech will implement the “Site and Temporary Facilities Plan” (see Appendix F) to provide

the temporary support facilities needed for the IRM. Tetra Tech will provide such facilities and

designate staging, storage, and lay down areas for the IRM work. Tetra Tech and subcontractors

will work out of vehicles with cellular phones in lieu of providing a field office. Tetra Tech will

use the fire hydrant located north of Tilley Chemical for water supply per Lockheed Martin

Corporation Properties, Inc. (LMCPI) request. Rented roll-off containers and fractionation (frac)

tanks (which will be used to contain the sediment/debris and water removed from the storm drain

pipes, inlets and manholes) will be staged near work areas and relocated as necessary for

efficient loading. Once full, the containers will be staged on the concrete slab of former

Building D in Block E and managed in accordance with the “Waste Management Plan.”

3.3.8 Environmental Protection and Erosion Controls

Tetra Tech will establish and maintain sediment and erosion control measures in accordance with

the “Environmental Protection and Erosion Control Plan” (see Appendix I) to minimize turbidity

and the transport of suspended solids and other materials that could degrade water quality. Both

temporary and permanent control measures will be employed, including silt fencing around each

inlet, curb diversion, outfall plugs, roll-off containers for sediment collection, frac tanks for wash

water collection, and seeding or paving repair at work completion. Runoff diverted from

disturbed areas will be conveyed to a sediment-trapping device. The method for temporarily

plugging the outfalls is described in the next section.

Tetra Tech will make a pre-disturbance site video to document conditions before fieldwork

begins. Tetra Tech will mark the planned disturbance areas, clear any vegetation and saw cut any

competent concrete or asphalt surface before any excavation work. Tetra Tech and its

subcontractors will, to the extent practicable, minimize disturbance areas. Temporary control


measures will be inspected daily and after each rain. Before control measures are removed,

disturbed areas will be stabilized or permanent stabilization will be established.

3.3.9 Temporary Plugs on Outfalls

All outfalls will be plugged, due to the interconnectedness of the sewer lines. As specified in the

“Construction Methodology Plan” (see Appendix J), the discharge pipes (24"–32" in diameter) for

Outfalls 05, 06 and 08 will be plugged using the following procedure when any pipe segment is

being cleaned:

• The plug will be a “flow through” type with a drain valve installed on the downstream side of the plug and inflated to the manufacturer’s recommended pressure. A pressure gauge will be included with each plug and will be monitored every two (2) hours during the work day.

• The plug will remain in place during all cleaning activities and will be removed at the end of the work day. Residual water accumulated on the upstream side of the plug will be removed before the plug is removed.

• Water will be removed by attaching a vacuum hose to the drain valve.

3.4 IRM CONSTRUCTION

3.4.1 Pre-Construction Walkthrough and Work Area Breakdown

A pre-construction walkthrough of the entire lengths of the Block E storm drain drainage pipes

will be conducted before construction of the IRM. All inlets and manholes will be visually

inspected to document any changes from the June 2009 storm drain survey observations

(summarized in Table 3-1). Inlets and manholes identified in 2009 as needing repair or

replacement are listed in Table 3-2. Both tables will be updated by adding a column with the

pre-construction observations.

3.4.2 Storm Drain System Cleaning

The base crew will consist of a cleaning operator and video inspection technician equipped with

a jet/vacuum truck and mobile closed-circuit television (CCTV) truck. The crew will hold a

tailgate safety meeting at the start of each day to review expected job hazards. All work will be

done from above ground except in those instances where access to a drainage pipe is limited and


confined space entry is necessary. In those instances, structures will be entered in accordance

with OSHA and the site-specific HASP procedures for confined space entry.

As indicated in the previous section, cleaning will begin with the Outfall 05 sewer line and

associated inlets and manholes, then continue with the Outfall 08 system, and end with the

Outfall 06 line. Cleaning will progress according to the pipe segments listed in Table 3-3 and

shown in Figures 2-3 to 2-5.

Cleaning will generally be suspended for the day whenever it rains. Cleaning may continue

during light rain as long as the storm does not surcharge the pipe segment being cleaned and

flood the drainage. Cleaning will entail:

• Removal of sediment and debris from the inlets and manholes with a jet/vacuum truck or by hand and contain the solids into an open-top watertight roll-off container. The fire hydrant located north of Tilley Chemical will be used for water supply.

• Jet cleaning of the drainage pipe and removal of solids and liquids with a jet/vacuum truck and contain in an open-top watertight roll-off container and frac tank. Drainage pipes will be cleaned only after all structures are cleaned. Sediment and wastewater containers will be relocated as needed.

• Video inspection of the drainage pipe with CCTV cameras to verify that the pipes have been cleaned

Details of pipe cleaning are included in the “Construction Methodology Plan” (see Appendix J).

3.4.3 Repair/Replace Inlets and Manholes

Manholes and inlets will be repaired or replaced as indicated in Table 3-2 and as necessary per

field conditions. Repairs will be performed as a whole once cleaning of the Block E storm drain

system is complete, and in accordance with the design plans (Appendix B) and technical

specifications (Appendix C). Inlets or manholes on unusable pipe segments will not be repaired.

Repairs and replacement work will be completed taking care not to allow debris to drop into the

cleaned drainage system. A typical detail of the manholes/inlets is provided in the design plans.

Required repairs to these structures vary and cannot be completely determined until each

structure is cleaned. Additional repairs other than those identified in Table 3-2 may be needed

once cleanout allows inspection of the inlet/manhole. Repairs will be made using brick, concrete,


grout, and cast-iron frames and covers with, as needed, crushed stone backfill and concrete,

asphalt, or vegetative surface finishes to return the structure/location to its original or better

condition. All repairs will be documented in tables, as-built drawings, and photographs.

3.4.4 On-Site Water Treatment and Discharge

Tetra Tech is investigating the possibility of on-site treatment and discharge to the publicly

owned treatment works (POTW) as an alternate wastewater disposal method. This alternative

would involve the mobilization and operation of a 100-gallon per minute system with bag filters

and granular activated-carbon to treat up to 20,000 gallons per day. The system would treat water

by filtration and carbon adsorption every one to four days to empty the frac tank(s) (used to

contain the water generated by the IRM).

If discharge to the sanitary sewer is approved, Tetra Tech will prepare an addendum to this

Design Report to provide operational details for the system, including MDE-licensed operator

supervision, filters, carbon, a post-treatment holding tank, marking of the approved discharge

manhole, generator, fuel/fuel tank, and the management and disposal of associated wastes (spent

bag-filters and carbon). The addendum will include field forms to document volumes of water

treated by the system. It will also discuss laboratory analyses required by Baltimore County.

Tetra Tech assumes that testing for PCBs and PAHs and other parameters will be required for

approximately every 20,000 gallons discharged, based on the November 1, 2010 Block B

discharge permit.

3.5 POST-CONSTRUCTION ACTIVITIES

Post-construction activities will consist of site restoration, a post-construction land survey, waste

disposal, preparation of the final site remediation report, and monitoring and maintenance of the

restored areas and drainage system. The post-construction survey will be performed as discussed

in section 3.2.4 to confirm that site features and elevations are consistent with pre-construction

conditions. Other post-construction activities are detailed in subsequent sections and in

Appendix J (“Construction Methodology Plan”).


3.5.1 Site Restoration

Upon completion of the IRM activities, all disturbed areas will be restored to approximately

pre-existing grades. The paved and/or other areas covered with concrete disturbed by the IRM

work will be restored to their pre-existing state as documented in the pre-disturbance video.

Concrete for structures directly affected by the cleaning will also be replaced. Seed and mulch

will be distributed across all disturbed vegetated areas. A post-construction walkthrough and a

post-cleaning video survey of selected portions of the Block E drainage pipes will document site

restoration activities and ensure that all manhole covers or inlet grates have been returned to their

respective structures. Restored areas will be monitored and maintained for one complete growing

season, provided the subject areas are not used for storage, continued development, or

construction by others within the defined timeline.

3.5.2 Drainage System Maintenance

Maintenance of the drainage system capacity will be limited to (1) use and maintenance of

sediment control measures installed during the cleaning phase (e.g., silt fence installed around all

inlets); and (2) replacement activities including additional/new sediment control measures

following completion of the IRM. The Block E storm drain system will be maintained by

LMCPI.

3.6 WASTE MANAGEMENT AND ESTIMATED WASTE VOLUMES

Wastes generated from the IRM construction will be handled as investigation-derived waste

(IDW) in accordance with the “Waste Management Plan” (Appendix H) and will consist of

sediment/debris, wastewater, and PPE. Sediment/debris waste is anticipated to include sediment,

sludge, dirt, sand, rocks, concrete, grease, roots, and other solid or semisolid material. The

sediments/debris extracted during the cleaning of storm drain system will be saturated (i.e.,

contain free liquids). The sediments/debris will be allowed to settle in collection roll-offs

designated for sediment/debris collection before being loaded onto transport vehicles for off-site

disposal. Water resulting from dewatering of the sediment/debris will be collected and

transferred to the water-frac tanks for subsequent disposal as PCB-contaminated water or on-site

treatment if a permit is obtained from Baltimore County.


If wastewater discharge to the POTW is approved, the wastes will also include spent bag-filters

and spent granular activated-carbon. Wastewater will consist of wash water from the drainage

pipe cleaning, decontamination rinse water, and frac tank and roll-off container rinse water.

Sediment/debris and wastewater will be contained on-site in rented watertight containers, which

will be appropriately labeled and stored in the concrete slab on Block E pending

chemical/physical characterization and proper disposal. Waste management details are included

in Addendum #1 to the “Waste Management Plan,” which is also included in Appendix H. The

anticipated waste volumes and anticipated waste classifications are discussed below. Refer to

Appendix H for additional details.

3.6.1 Sediment/Debris

Approximately 75 tons of sediment will be removed (based on the 2009 survey). As indicated in

section 2, Toxicity Characteristics Leaching Procedure (TCLP) organic and inorganic and

Resource Conservation and Recovery Act (RCRA) characteristics were analyzed for in six of the

sediment samples collected in 2009 to determine if the sediment is a RCRA hazardous waste as

defined by federal and state regulations, and to evaluate disposal methods. The results indicate

that the sediments in the Block E storm drain system are not a RCRA hazardous waste. However,

some sediments will be considered polychlorinated biphenyl (PCB)-containing wastes and will

have to be handled in accordance with Toxic Substance Control Act (TSCA) requirements

(40 CFR 761).

For compliance with the “PCB Rule,” those sections of pipe with 50 mg/kg PCB or greater

concentrations will be designated and disposed of as a TSCA material. Sediment sampling in

2009 indicates that the sediments in MH-3 and IL-18 contain PCBs greater than 50 mg/kg;

therefore, the sediments/debris removed from the sewer pipes extending from MH-4 to the two

discharge points of Outfall 05 and between IL-18 and IL-19, and in the westward extension from

IL-18, will be considered PCB-containing TSCA-controlled material and will be collected in

segregated containers.

3.6.2 Wastewater

Tetra Tech estimates that 60,000 gallons of water will be required for cleaning and subsequent

collection during the IRM construction. This volume is based on approximately 5,000 gallons of


water per day for the 10–15 day cleaning-project schedule. Wastewater will be transported for

off-site disposal, which will be by means of activated-carbon treatment. Every attempt will be

made to minimize water use; however, sewer cleaning usually requires high volumes of water.

The wastewater will be classified as PCB-contaminated water; this classification may change

pending laboratory analysis results.

3.7 DOCUMENTATION

Documentation for this project will include a site logbook, pre-disturbance site video, cleaning

inspection video logs, post-cleaning survey video, and pre- and post-construction land surveys

with as-built drawings, laboratory analytical results, and documentation of transportation and

off-site disposal of wastes. If wastewater is treated on-site for discharge to the POTW, associated

field forms will also be included in the project documentation. Documentation will be provided

in the Final Site Remediation Report.

The site logbook will be maintained and updated with information collected as part of the

Block E IRM. Sample custody-procedures will be followed to document sample acquisition and

integrity. All samples will be shipped with a chain of custody report summarizing and

documenting pertinent sample information, such as sample identification and type, matrix, date

and time of collection, preservation, and requested analysis.

MH-8, MH-9 — Both manholes are buried at the ground surface (not visible from ground surface). MH-9 is backfilled with cobbles and rocks and was discovered during the MH-10 (IL-3) pipe video inspection. MH-8 and the pipe from MH-9 to MH-8 could not be inspected due to a blocked pipe and buried manholes. Joint separation: 2.2 ft at joint—medium Joint offset: 6.1 ft at joint—medium 9.7 ft at joint—medium 13.8 ft at joint—medium

Section 4

Regulatory Notifications and Requirements

The United States Environmental Protection Agency (USEPA) has been notified of the Interim

Remedial Measures (IRM) work planned for the Block E storm drain system. The USEPA and

the Maryland Department of the Environment (MDE) will review this Design Report, the final

design package, and the attached construction plans to approve the IRM work. Public

involvement requirements will be met by the Lockheed community outreach program.

Discussions with MDE and USEPA staff indicate that “National Pollutant Discharge Elimination

System” permits will not be required for this project because water and sediment will be

contained. Per conversations with Mr. Jeff Rice of Baltimore County Development Plans Review

(410-887-3751), no county permits will be needed to clean the Block E storm drain system, as it

is inside Lockheed Martin property and not on public right-of-way.

Permits will be required from Baltimore County to discharge the wastewater to the sanitary

sewer as an alternative option for management and disposal of wastewater generated by the IRM.

Tetra Tech has been in contact with Mr. John Burnett (410-887-5488) of the Baltimore County

Department of Public Works and has obtained a permit for discharge at Block B. We have not yet

determined if we will attempt to obtain a permit specifically for this IRM work.

The “PCB Rule” in 40 CFR 761 regulates polychlorinated biphenyl (PCB) removals. All “PCB

Rule” requirements for storage, transportation, and disposal of water and materials will be met

for cleaning operations in pipe segments where PCB concentrations of 50 mg/kg PCB or greater

have been measured in previous sampling investigations. “PCB Rule” requirements applicable to

this project are discussed in Appendix G. As indicated previously, these IRM actions are not

designed to achieve the preliminary sediment cleanup goals but rather to remove the more

mobile sediments that could migrate off-site from the drainage system. The IRM is part of

routine maintenance of the facility’s storm-water collection system. A report of IRM actions will


be provided in the Final Site Remediation Report, which will be prepared at the conclusion of the

work.


Section 5

Project Schedule

The proposed project schedule is presented in Appendix D. It was developed using Microsoft

Project 2007® and includes a “Critical Path Network” to successfully complete the work within

the allotted time. It will be updated during the 90% design package and final (100%)

construction documents phases. After mobilization to implement the interim remedial measures,

the schedule will be revised as needed, with appropriate notification of Lockheed Martin.

Notes

1 Boring identification indicated corresponds to soil boring locations shown on Figure 3-1. 2 Sampling interval measured from surface whether soil or concrete. A sample designated as 2 feet will include

the interval from approximately 22 to 26 inches below grade and so forth for other depths indicated. Soil borings SB-541 through SB-571 were installed during the first phase of the sampling event with analysis conducted in a fixed base laboratory with approximately a 5-day turnaround time. The analytical laboratory was directed to either analyze or dispose the 'as needed' soil samples based on the analytical results for contiguous samples as directed by Tetra Tech.

Section 1

Introduction


Construction Quality Control Plan to support implementation of Interim Remedial Measures

(IRM) at the Tax Block E storm drain system of the Middle River Complex in Middle River,

Maryland. The IRM work will consist of (1) cleaning and removing sediment from storm drain

lines with containment and disposal of liquid and solid material, (2) repair of inlets and manholes,

and (3) abandonment of storm drain lines, inlets and manholes that are no longer serviceable. This

Construction Quality Control Plan (CQCP) is a companion document to the Design Report; it

establishes project procedures and general responsibilities for the quality control program to

ensure that IRM implementation is executed in accordance with the relevant portions of the

Design Report.

The objectives of this CQCP are to:

• Describe the quality program and organization to be implemented so that the project is conducted in accordance with contract requirements and industry standards;

• Describe guidelines for inspection and documentation of activities;

• Provide reasonable assurance that the completed work will meet or exceed the requirements of the construction drawings and specifications;

• Describe the approach for confirming that the IRM have been achieved for a specific location; and,

• Describe how any unexpected changes or conditions that could affect the construction quality will be detected, documented, and addressed during construction.

Tetra Tech is responsible for conducting the work in accordance with approved plans and

specifications. Each subcontractor is also responsible for controlling the quality of its work to

meet contract plans, specifications, and related requirements. Quality Control (QC) is the

TETRA TECH: LOCKHEED MARTIN MIDDLE RIVER COMPLEX CONSTRUCTION QUALITY CONTROL PLAN – BLOCK E STORM DRAIN SYSTEM IRM PAGE 1-2

systematic implementation of a program of inspections, tests, and controls to attain the required

standards of quality and to preclude problems resulting from noncompliance.

Tetra Tech will provide QC through daily monitoring and scheduled inspections to verify that

contract requirements are being met. Tetra Tech's On-Site Supervisor (OSS) will be responsible

for the day-to-day coordination of quality control measures in the field. The OSS will assure that

QC is working effectively and that the resultant construction complies with the quality

requirements established by the contract.

1.1 CQCP ORGANIZATION

This Construction Quality Control Plan is organized as follows:

Section 1 — Introduction: Provided the CQCP quality program overview.

Section 2 — Project Quality Control/Quality Assurance (QC/QA) Organization: Presents the organizations and key personnel involved in the IRM, their responsibilities and authorities, the structure of the QC/QA organization and the minimum training and experience of personnel.

Section 3 — Inspection and Verification Activities: Provides procedures for tracking construction inspection and verification activities for the contract, construction acceptance criteria, and construction audits.

Section 4 — Construction Deficiencies: Describes the procedures for tracking construction deficiencies from identification through acceptable corrective action.

Section 5 — Field Changes: Describes handling of quality plan changes to assure QC/QA objectives are met.

Section 6 — Documentation: Describes the procedures for the project documents that will be managed in a secure document filing and storage system.

TETRA TECH: LOCKHEED MARTIN. MIDDLE RIVER COMPLEX INTERIM REMEDIAL MEASURES DESIGN REPORT – BLOCK E STORM DRAIN SYSTEM PAGE 3-1

Section 3

Inspection and Verification Activities

3.1 GENERAL CONSTRUCTION INSPECTION AND VERIFICATION REQUIREMENTS

Tetra Tech and all subcontractors will perform the inspections and tests as prescribed in the

technical specifications. Quality Assurance (QA) inspection and testing will be used to verify the

adequacy and effectiveness of the contractor Quality Control (QC) program.

3.1.1 Inspections

Tetra Tech will establish a program for inspection of activities affecting quality and shall cover the

entire construction site. Inspections shall be performed to verify compliance with documented

instructions, drawings, procedures, and specifications as required by the contract. All inspections

shall be documented by the contractor. A four-phase inspection program shall be followed for

each definable feature of the work. The four phases of inspection are:

1. Preparatory Inspection

The Tetra Tech On-Site Supervisor (OSS) performs preparatory inspections prior to beginning any

work on any definable feature of the work.

• Ensure that preparatory inspections include a review of contract requirements.

• Ensure that all materials and /or equipment have been tested, submitted, and

approved.

• Ensure that provisions have been made to provide required testing.

• Examine work area to ascertain that all preliminary work has been completed.

• Examine materials and equipment to ensure that they conform to design

documents, that all materials and/or equipment are on hand, and that all monitoring

and measuring equipment is properly calibrated and in proper working condition.


• Record preparatory inspections in the QC documentation.

2. Initial Inspection

The OSS performs an initial inspection as soon as a representative portion of the particular feature

of work has been accomplished.

• Examine the quality of workmanship.

• Review control testing for compliance with contract requirements.

• Review dimensional aspects of the work.

• Record initial inspections in the QC documentation.

3. Follow-Up Inspection

The OSS performs follow-up inspections daily.

• Ensure continuing compliance with Contract requirements.

• Ensure continuing compliance with control testing until completion of particular

feature of work.

• CQM records follow-up inspection in daily QC reports.

• The OSS inspection staff records follow-up inspections in their daily inspection

report.

• Conduct final follow-up inspections and correct test deficiencies prior to the

addition of new features of work.

4. Completion Inspection

The OSS performs a completion inspection of the work.

• Develop a “punch list” of items that do not conform to the approved plans and

specifications.

• Include the punch list in the construction QC documentation. Include the estimated

date by which the deficiencies will be corrected.

• Perform a second completion inspection after punch list items have been

completed.


The daily inspection reports shall identify inspections conducted, results of inspections, location

and nature of defects found, causes for rejection, and remedial or corrective action taken or

proposed.

When deficiencies are discovered during the four-phase or other inspection processes, a Camp,

Dresser and McKee, Inc. (CDM) representative will be informed of any quality issues and the

resolution. When material or performed work is found on the basis of focused inspections to be

deficient and/or does not meet the project specifications, a CDM representative will assure

deficiency correction is implemented, as discussed in Section 4.

3.1.2 Construction Audits

Tetra Tech will establish and document an auditing system to verify its own (or its sub-

contractor’s) implementation of and conformance to the CQCP and contract technical

specification requirements. The auditing system shall be used to make a determination regarding

the effectiveness of the QC system.

Audits shall be performed by qualified and properly trained personnel who are familiar with the

QC system, auditing procedures and techniques. Selection of auditors and the conduct of audits

shall ensure the objectivity and impartiality of the audit process. Auditors shall not audit their own

work. The auditing system shall cover all the quality-affecting activities for construction. The

results of the audits shall be documented and reported to the OSS. All non-conformance

conditions identified during the audit shall be re-audited to verify the corrective actions taken by

the appropriate organization were effective.


Section 4

Construction Deficiencies

This section provides procedures for tracking construction deficiencies (noncompliance) from

identification through acceptable corrective action. It defines the controls and related

responsibilities and authorities for dealing with noncompliant products or services.

Deficiency occurs when performed work does not meet the plans and/or specifications for the

project.

4.1 CONTRACTOR QC DEFICIENCY IDENTIFICATION AND CONTROL

When performed work is found deficient, a Camp, Dresser and McKee, Inc. (CDM) representative

(or designee) shall ensure that the non-conforming work is identified and controlled to prevent

unintended use or delivery. They will notify the contractor of any noncompliance with any of the

foregoing requirements. Tetra Tech will, after receipt of such notice, immediately take corrective

action. Minor deficiencies noted during inspection are verbally reported to the On-Site Supervisor

(OSS) and noted on the Daily Construction Report. Minor deficiencies are items that do not

require significant rework or repair work to correct, and will not result in significant deviations

from required quality standard if corrected immediately.

Control and disposition of such deficiencies shall be by the originator of the Daily Construction

Report and the OSS responsible for the work and do not require formal action by the CDM

representative. Ideally, such minor deficiencies can be corrected on the spot by agreement with the

OSS. Non-conformances are major deviations from the contract requirement and/or accepted

standard of quality, which must be formally documented for corrective action by Tetra Tech and

subcontractors or the third party testing group.


4.2 CONTRACTOR DEFICIENCY CORRECTION

When performed work is found to be deficient and/or does not meet the project specifications, the

CDM representative will assure deficiency correction is implemented. The CDM representative

shall ensure that the non-conforming work is identified and controlled to prevent unintended use.

The CDM representative is responsible for documenting the non-conformance.

Tetra Tech will implement corrective actions to remedy work that is not in accordance with the

drawings and specifications. The corrective actions will include removal and replacement of

deficient work using methods approved by the CDM representative. Replacement must be done in

accordance with the corresponding technical specifications. Replacement will be subjected to the

same scope of QC/QA inspection and testing as the original work. If the replacement work is not

in accordance with the drawings and specifications, the replacement work will be removed,

replaced, re-inspected, and re-tested.

4.3 PREVENTIVE ACTIONS

Preventive actions are taken to eliminate the cause of a potential non-conformity. Tetra Tech shall

take preventive actions as necessary to eliminate the causes of potential deficiencies so as to

prevent their occurrence.


Section 5

Field Changes

Field changes for Quality Control/Quality Assurance (QC/QA) will be limited to Construction

Quality Control Plan (CQCP) changes. Changes to construction processes or design plans and

specifications are governed by the design change order procedures.

5.1 CQCP CHANGES

The Lockheed Martin, On-Site Supervisor (OSS) or Camp, Dresser and McKee, Inc. (CDM)

representative may initiate revisions to this CQCP. The CQCP may be revised when it becomes

apparent that the CQCP procedures or controls are inadequate to support work being produced in

conformance with the specified quality requirements or are deemed to be more excessive than

required to support work being produced in conformance with the specified quality requirements.

Changes to QA procedures necessitating modification to this CQCP will be initiated by the CDM

representative for OSS and Lockheed Martin approval.

5.2 QC CHANGES

Tetra Tech’s CQCP may require revisions as necessary to correct unsatisfactory performance. At

any time after approval, Lockheed Martin may require Tetra Tech to make changes to the CQCP,

including personnel changes, as necessary to obtain the quality specified. Moreover, Tetra Tech

may initiate CQCP changes to correct QC process problems, and is required to notify the CDM

representative in writing of any desired changes; all changes are subject to Lockheed Martin and

CDM acceptance.


Section 6

Documentation

Quality Control (QC) documentation must cover all aspects of QC program activities, and

includes Daily Inspection Reports and Daily Test Reports.

6.1 DAILY RECORD KEEPING

Project documents will be managed through a combination of a secure document filing and storage

system. Sufficient records shall be prepared and maintained as work is performed to furnish

documentary evidence of the quality of construction and of activities affecting quality. Each QC

technician shall maintain a daily log of all inspections performed for both contractor and

subcontractor operations on a form acceptable to the On-Site Supervisor (OSS) and Camp, Dresser

and McKee, Inc. (CDM) representative.

The Daily Inspection shall be signed by the responsible QC technician and the OSS. The OSS

shall be provided at least one copy of each daily inspection on the work day following the day of

record.

6.2 DAILY CONSTRUCTION REPORT

Section 1

Site and Temporary Facilities Plan

On behalf of Lockheed Martin Corporation, Tetra Tech, Inc. (Tetra Tech) has prepared this Site

and Temporary Facilities Plan to support implementation of Interim Remedial Measures (IRM) at

the Tax Block E storm drain system of the Middle River Complex in Middle River, Maryland.

This plan provides details for the construction staging and storage areas, decontamination

facilities, and water and sediment collection facilities that will be required to perform the IRM.

1.1 GENERAL STAGING AREA

The northeast corner of Block E will be used as the general staging area during the IRM

construction. In lieu of providing a temporary field office, Tetra Tech staff and subcontractors will

work out of work vehicles. Communications will be provided by cellular telephones. Sanitary

facilities will consist of a wash station provided with portable toilets, while bottled water will be

provided for drinking.

1.2 CONSTRUCTION STAGING AND LAYDOWN AREAS

The staging area will be limited to the northeast corner of Block E as it has a concrete surface

which will minimize soil erosion. The staging area will be designated and will be large enough to

safely accommodate construction equipment, materials, parking, decontamination pads, water

storage, and sediment storage areas. The location of the construction staging area is identified on

the Environmental Protection and Sediment Erosion Control Plan (EP&SECP). Tetra Tech will

work closely with Lockheed Martin Properties, Inc. (LMCPI) to stage the equipment (jet/vacuum

truck) and material (sediment/debris and water collection boxes) to minimize impacts to Middle

River Complex operations.


1.2.1 Construction Entrance

The northeast corner of Block E will serve as the official construction entrance and will be

maintained in a condition that will prevent tracking or flowing of sediment outside of Block E.

Maintenance of the construction entrance will require periodic sweeping. The construction

entrance will be inspected throughout each work day by the Field Operations Leader to ensure that

it is properly maintained.

1.2.2 Decontamination Pad

Trucks used during IRM implementation (e.g., jet/vacuum truck and sediment and water

transportation trucks) will remain on clean surfaces and any sediment/soil adhering to siderails and

tailgates will be removed while in the designated construction staging area. A temporary

decontamination pad will be established to clean trucks and equipment. The pad will be sized to

accommodate all the equipment to be used during IRM implementation and will be constructed in

a manner that contains all the contaminated materials removed from equipment and the liquids

used to clean the equipment. The pad will be constructed with polyethylene sheeting and tire mats

to contain decontamination fluids which will then be conveyed to a portable sediment tank. The

pad will be of a minimum size to park the equipment and vehicles working at the site (e.g., 20 feet

by 50 feet).

1.3 WATER SUPPLY

Tetra Tech will use the fire hydrant located north of Tilley Chemical for water supply per LMCPI

request. Use of water will be coordinated with Steve Thompson of LMCPI.

1.4 WATER AND SEDIMENT COLLECTION FACILITIES

1.4.1 Water Collection

Water removed from the storm drain pipes, inlets and manholes will be containerized in rented

fractionation (frac) tanks which will be staged near the work areas and relocated as necessary for

efficient loading. Once full, the containers will be staged on the designated construction staging

area in the northeast corner of Block E. After characterization testing, the water will be pumped


out into a vacuum truck for off-site disposal. At the completion of the project, empty frac tanks

will be rinsed three times with water from the fire hydrants; the rinse water will also be trucked for

off-site disposal. All water will be disposed at an approved disposal facility in accordance with the

Waste Management Plan. Tetra Tech is investigating the possibility of on-site treatment and

discharge to the publicly owned treatment works (POTW) as an alternate wastewater disposal

method. This alternative would involve mobilization of a temporary water treatment system. If

discharge to the POTW is approved, Tetra Tech will prepare an addendum to this plan to provide

details for the system.

1.4.2 Sediment/Debris Collection

Sediment and debris removed from the storm drain pipes, inlets and manholes will be

containerized in rented, watertight roll-off containers which will be staged near the work areas and

relocated as necessary for efficient loading. The sediment/debris waste is anticipated to include

sediment, sludge, dirt, sand, rocks, concrete, grease, roots, and other solid or semisolid material.

The sediments/debris will be tested for polychlorinated biphenyls (PCBs) and properly disposed

off-site.

Sediments/debris removed from sections of the sewer line associated with Outfall 05 will be

considered PCB-containing and will be stored separately as detailed in the next section.

1.4.3 PCB-Containing Sediment Collection

Sediment sampling completed in 2009 indicated PCB concentrations greater than 50 mg/kg at two

locations: IL-18 and MH-3. Therefore, sediment/debris/soil removed from the storm drain

segments extending from MH-4 to both discharge points on Outfall 05 and between IL-18 and

IL-19, and in the west extension from IL-18 will be considered PCB-containing federal Toxic

Substances Control Act (TSCA)-controlled material and will be stored in separate, lined watertight

roll-off containers. The roll-offs will be properly labeled and stored in the waste drum

accumulation area of Block E. Storage, handling, testing and disposal will be in accordance with

TSCA requirements.


1.4.4 Waste Dewatering

The sediments/debris extracted during the cleaning of storm drain system will be saturated

(contain free liquids). The sediments/debris will be allowed to settle in lined collection roll-offs

designated for sediment/debris collection prior to removing the free water and loading the settled

solids onto transport vehicles for off-site disposal. The time designated for settling will be

determined based on the nature and volume of the removed sediment/debris. The lined roll-offs

may be maneuvered as necessary included inclining one end to allow more complete drainage of

free liquids prior to transportation and disposal. Water resulting from the sediment/debris

dewatering will be transferred to the water frac tanks for subsequent disposal as PCB-impacted

water or on-site treatment if a permit is obtained from Baltimore County.

1.5 EQUIPMENT DECONTAMINATION

Equipment used during the completion of the IRM will be decontaminated to prevent potential

transfer of contaminants to areas where they are currently not present. The decontamination

procedure will involve the removal of gross soils/contamination using hand tools followed by a

low-flow, high-pressure wash. All wash water will be collected from the decontamination pad via

pump, transferred to the frac tanks, tested for PCBs, and properly disposed off-site. Sediments

will be removed manually with a shovel and containerized in the corresponding non-PCB or

PCB-containing sediment collection container. Equipment that comes in contact with PCBs will

be decontaminated in accordance with 40 CFR 761 requirements. The washes/rinses will be

followed up with wipe tests for PCBs.

1.1 SITE SPECIFIC HEALTH AND SAFETY PLAN (SSHASP)

The SSHASP was constructed on the framework of a Master Health and Safety Plan (MHASP) for

Lockheed Martin which must be maintained on-site. This SSHASP must be used in conjunction with the

Tetra Tech Health and Safety Guidance Manual (HSGM). The HSGM contains Tetra Tech Health and

Safety Standard Operating Procedures (SOPs), as well as detailed reference information on a variety of

topics. This SSHASP and where referenced the contents of the HSGM were developed to comply with

the requirements stipulated in 29 CFR 1910.120 (OSHA’s Hazardous Waste Operations and Emergency

Response Standard) and applicable sections of 29 CFR 1926 (Safety and Health Regulations for

Construction). Therefore both documents including the LM Remediation Contractors ESH Handbook must

be onsite to achieve regulatory and local requirements.

1.2 LM REMEDIATION CONTRACTORS ESH HANDBOOK

In addition, the contractor responsibilities stipulated in Section 1 of the LM Remediation Contractor’s ESH

Handbook (LM Handbook) will be adhered to. The LM Handbook can be found in Attachment I of this

SSHASP. A copy of this must also be maintained onsite and available to all personnel.

Copies of the pertinent environmental, safety and health (ESH) records must be maintained Uat the job

site. UThis includes, but is not limited to:

SSHASP for this site where work is being conducted

The Tetra Tech HSGM

Personnel training documentation

Evidence of enrollment in a medical surveillance program

Monitoring results

Air sampling data

Waste materials inventory and container inspections.

These records must also be provided electronically to the LM Project Lead.

This SSHASP has been developed using the latest available information regarding known or suspected

chemical contaminants and potential physical hazards associated with the proposed work and site. The

SSHASP will be modified if the scope of work changes or if new information regarding site conditions,

hazards, or contaminants of concern becomes available. If deviations are encountered from the field

work plan, the contractor shall:

Notify to the LM Project Lead Suspend work to assess changes to the work plan(s) and the SSHASP.

Changes to the work plan(s) and the SSHASP shall be reviewed and approved by the Project Lead

before work can commence. Procedures addressing changes to this SSHASP as described in Section 6

of the LM Handbook (Attachment I) will be followed.

2.0 EMERGENCY ACTION PLAN

2.1 INTRODUCTION

This section has been developed as part of a planning effort to direct and guide field personnel in the

event of an emergency. In the event of an emergency, the field team will primarily evacuate and

assemble to an area unaffected by the emergency and notify the appropriate local emergency response

personnel/agencies. Workers who are ill or who have suffered a non-serious injury may be transported

by site personnel to nearby medical facilities, provided that such transport does not aggravate or further

endanger the welfare of the injured/ill person. The emergency response agencies listed in this plan are

capable of providing the most effective response, and as such, will be designated as the primary

responders. These agencies are located within a reasonable distance from the area of site operations,

which ensures adequate emergency response time.

Tetra Tech personnel may participate in minor event response and emergency prevention activities such

as:

Initial fire-fighting support and prevention

Initial spill control and containment measures and prevention

Removal of personnel from emergency situations

Provision of initial medical support for injury/illness requiring only first-aid level support

Provision of site control and security measures as necessary

2.2 EMERGENCY PLANNING

Through the initial hazard/risk assessment effort, emergencies resulting from chemical, physical, or fire

hazards are the types of emergencies which could be encountered during site activities. To minimize or

eliminate the potential for these emergency situations, pre-emergency planning activities will include the

following (which are the responsibility of the SSO and/or the FOL):

Coordinating with LM Middle River and/or local emergency response personnel to ensure that Tetra

Tech emergency action activities are compatible with existing emergency response procedures.

Establishing and maintaining information at the project staging area (support zone) for easy access in

the event of an emergency. This information will include the following:

Chemical Inventory (of chemicals used onsite), with Material Safety Data Sheets.

Onsite personnel medical records (Medical Data Sheets).

A log book identifying personnel on-site each day.



Hospital route maps with directions (these should also be placed in each site vehicle).

Emergency Notification - phone numbers.

The Tetra Tech FOL will be responsible for the following tasks:

Identifying a chain of command for emergency action.

Educating site workers to the hazards and control measures associated with planned activities at the

site, and providing early recognition and prevention, where possible.

Periodically performing practice drills to ensure site workers are familiar with incidental response

measures.

Providing the necessary equipment to safely accomplish identified tasks.

2.3 EMERGENCY RECOGNITION AND PREVENTION

2.3.1 Recognition

Emergency situations that may be encountered during site activities will generally be recognized by visual

observation. Visual observation will play a role in detecting potential exposure events to some chemical

hazards as well as physical hazards. To adequately recognize chemical exposures, site personnel must

have a clear knowledge of signs and symptoms of exposure associated with the principle site

contaminants of concern as presented in this SSHASP. Tasks to be performed at the site, potential

hazards associated with those tasks and the recommended control methods are discussed in detail in

Sections 5.0 and 6.0.

Daily site surveys will be another method site personnel will employ to support early recognition of

hazards. Hazards detected will be eliminated/isolated that could predispose site personnel property or the

environment to an emergency situation or condition.

While the FOL and/or the SSO will be tasked and exercise primary responsibility for performing surveys of

work areas prior to initiating site operations and periodically while operations are being conducted all

personnel will play an active role in this activity supporting Tetra Tech health and safety policy.

Survey findings are documented by the FOL and/or the SSO in the Site Health and Safety or field

logbook, however, site personnel will be responsible for reporting hazardous situations. Where potential

hazards exist, Tetra Tech will initiate control measures to prevent adverse effects to human health and



the environment. Based on the planned scope of work the following sections discuss potential

emergencies that could arise and are recognized to be outside of field personnel to control if realized.

2.3.1.1 Storm Drain repairing/replacing inlets and manholes

Potential Emergency: Damaging an underground utility and permit required confined space entry.

Planned Control Measure: Utility location and clearance in accordance with Section 7.0 of the

HSGM and with the local One Call system. With this procedure direction is provided to the field crew

concerning passive detection methods to identify subsurface structures. These will include but not limited

to:

Utilization of Enviroscan – This is a subcontracted utility locate and clearance service.

All soil excavation and intrusive repair/replacement activities will proceed in accordance with the

Utility Locating and Excavation Clearance utilizing the areas One-Call system and identified passive

detection methods identified in Section 7.0 of the HSGM.

All utility clearances will be obtained, in writing, and locations identified and marked, prior to

activities. If it is not obtainable/unknown or you location infringes within 3-feet of an underground

utility advancement must proceed by hand to confirm the utility location. Pot-holing will be

conducted to verify the location of the utility prior to excavating/drilling in that area.

The typical timeline for marking and providing clearances is 2 days. A ticket or ticket number will be

provided referring to your clearance. Tickets must be maintained valid by asking for a re-issue or

extension, when necessary, prior to expiration.

Utility locations marked on the ground may not remain visible. The FOL is responsible for ensuring

that utility locations/marks on the ground are maintained so they remain visible (repaint, pin flags,

etc.), and to annotate maps with these locations so they may be incorporated into the Site map.

Once marks are placed on the ground and have been cleared, only limited leeway (3-feet) exists to

stray from the planned and approved intrusive locations.

Planned Control Measure – Jobsite Hazard Evaluation Site Surveys - As part of early recognition the

FOL and/or the SSO will conduct the following activities:

An initial site walk through will be conducted prior to the commitment of personnel or equipment. The

purpose of this walk through will be to:



Examine the site for conditions that may predispose field personnel to potential hazards including

- The existence of overhead power sources near where equipment will operate.

- Surface monuments indicating the existence of underground utilities in the area (manhole

covers, valve boxes, etc.).

- Areas that may require alterations of traffic patterns or scheduling when the work will be

conducted.

- Physical hazards within the work area.

- Terrain challenges.

Periodic operations surveys – FOL and/or the SSO will conduct these surveys for the purpose of:

Ensuring field personnel are following protective measures specified within the MHASP and the

SSHASP.

Review the initial hazard assessments to insure they reflect the hazards as it may pertain to site

specific conditions.

Prepare for Emergencies. This includes staging emergency equipment, adequate site control

measures, identifying site personnel who will perform incidental response measures and

reviewing what measures will be taken and when and by who prior to declaring an emergency.

These surveys should be documented in the project logbook. The results of these surveys are to be

discussed with the field personnel as part of the Tail gate Safety meetings.

Confined Space Entry Operations

All IRM work will be done from above ground except in those instances where access to a drainage pipe

is limited and it is necessary for confined space entry. In those instances, entry will be as specificed in

this SSHSP.

Planned Control Measure: As with any permit-required confined space operation, there are inherent

hazards that could lead to an emergency situation and/or condition. To control the potential hazards

associated with this task;

Entry operations will be coordinated with local Emergency Response Rescue Crews near the Martin

River Site. Local emergency services will provide rescue services, if needed, during confined space

entry operations. The details for notification must be documented in the Confined Space Entry

Permit. Coordination will include the following:



- An initial planning meeting to describe the activities to be conducted and the types of rescue

services required. In this particular case, a combination of vertical and horizontal rescues is

necessary due to the configuration of the confined space.

- Daily notification – When entering the confined space and when exiting the confined space.

The provisions stipulated in Attachment III, Tetra Tech NUS, Inc. Confined Space Entry Operations

Program, will be strictly adhered to in order to address foreseeable hazards. Through the application

of this program, control measures as well as provisions for self rescue will be incorporated into the

operation to control potential emergencies.

2.3.1.2 Storm Drain Repair Replacement Excavation Hazards – Struck By

Potential Emergency: Excavation Hazards/Equipment Movement hazards - Emergencies that could

occur during this activity are physical and include struck by equipment, trapped between operating

equipment and/or immovable objects, traffic hazards, falling into the open excavation(s), excavation

collapse. The control measures to minimize these hazards are:

Traffic Patterns in and around the work area. All heavy equipment (excavator, dump trucks, etc.)

will be routed in a singular direction. This will minimize backing, U-turns and other maneuvers that

could result in an accident. Area demarcation will be placed in plain view, so all personnel recognize

the extent of the swing pattern of the excavator. Operations will not permit the swing of the bucket

over persons, when in operation.

Excavations left open overnight will be demarcated by construction fencing and low intensity

blinking lights.

Falling into the open excavation – The following control measures will be used to guard against

persons or equipment falling into an open excavation.

Signage; Fences/barricades; sloping; and means of exit will be established to restrict approaching

excavation boundaries closer than 5-feet.

Traffic control blocks shall be placed to prevent trucks and other (than the excavator digging)

heavy equipment from approaching closer than 5-feet to the open excavation.

All excavations left open will be physically delineated using fences, barricade tape and placement

of blinking emergency warning lights on all sides of the open excavation.

Struck By/Caught Between – A number of incidents and fatalities have occurred on construction sites

as a result of personnel caught between operating equipment and immovable objects. In order to

prevent this from occurring field teams will follow the principles described below:



Always approach the operator from the front. Remain within the operator’s field of vision.

Always assume he/she does NOT see you. Do not approach until they have signaled they see

you and have placed the bucket on the ground.

Always have an escape pathway. Never place yourself between a truck or piece of operating

equipment and an immovable object.

Where personnel and heavy equipment must work within close quarters a noise producing device

should be provided to ground personnel to alert operators when and where necessary.

2.3.2 Prevention

General methods of prevention have been discussed above for situations that could quickly degrade into

an emergency situation. Through following elements described in this SSHASP and those on the Safe

Work Permits, conducting periodic site surveys, will minimize the potential for a situation to escalate into

an emergency condition. Preparation through acquiring and placing emergency equipment in the areas it

will be needed will also aid in controlling an incidental situation from escalating into an emergency

situation.

2.3.3 Fire Prevention / Flammable Liquids

Tetra Tech and subcontractor personnel are responsible for fire protection in all of their work areas at all

times during the duration of this field effort (24 hours per day/seven days per week). Approved fire-

fighting equipment and extinguishers, in adequate quantities for their work activates must be provided.

The following provisions will be established:

Motorized vehicles must be shut off during refueling.

Smoking will only be permitted in designated areas.

A 10:A120:BC fire extinguisher must be maintained onsite within 50-feet of the fueling station or

activity.

During fueling all equipment will be bonded to the fuel supply delivery system to control static charge.

If the fuel hose is not equipment with a bonding wire a separate independent bonding wire must be

established. These connections will be periodically checked for continuity.

All flammable and combustible liquids must be stored, dispensed and used in accordance with OSHA

regulations and the Uniform Fire Code. We will have either temporary storage (approximately 100

gallons) or a fuel service. Bonding and grounding of containers containing flammable liquids will be

required when transferring over 50 gallons.

Fuel containers will not be stored within 10’ of the unit motor, heat or ignition source.

Fuel will be stored only in appropriate UL approved safety containers with contents clearly labeled.



The LM Project Lead will be notified as soon as possible of any fire, if Tetra Tech or subcontractor

personnel use a LM fire extinguisher, and of any and all fires that are extinguished. In case of fire, Tetra

Tech will expend one fire extinguisher in an incidental response measure. If that fails to extinguish the

fire, the FOL and/or the SSO will call 9-1-1.

The fire prevention/flammable liquids safety procedures and requirements stipulated in Section 3.15 of

the LM Handbook (Attachment I) will also be adhered to.

2.4 EVACUATION ROUTES, PROCEDURES, AND PLACES OF REFUGE

An evacuation will be initiated whenever recommended hazard controls are insufficient to protect the

health, safety or welfare of site workers, property, or the environment. Specific examples of conditions

that may initiate an evacuation include, but are not limited to the following:

Severe weather conditions;

Fire or explosion;

Monitoring instrumentation readings which indicate levels of contamination are greater than instituted

action levels; and evidence of personnel overexposure to potential site contaminants.

Injury requiring medical transport and care.

Confined space emergency

In the event of an emergency requiring evacuation, personnel will:

Immediately stop activities

Call 911 dispatch emergency services (See Section 2.7)

Establish site security

Non-essential personnel report to the designated safe place of refuge or an alternate place of refuge

should access be blocked. These will be identified on the site map posted in the trailer and discussed

during the morning Tail Gate Safety meeting or issuance of the Safe Work permit.

Whenever possible, the safe place of refuge will also serve as the telephone communications point for

that area. During an evacuation, personnel will remain at the refuge location until directed otherwise by

the Tetra Tech FOL or the on-site Incident Commander of the Emergency Response Team. The FOL or

the SSO will perform a head count at this location to account for and to confirm the location of site

personnel. Emergency response personnel will be immediately notified of any unaccounted personnel.

The SSO will document the names of personnel onsite (on a daily basis) in the site Health and Safety

Logbook. This information will be utilized to perform the head count in the event of an emergency.



Evacuation procedures will be discussed during the pre-activities training session, prior to the initiation of

project tasks. Evacuation routes from the site and safe places of refuge are dependent upon the location

at which work is being performed and the circumstances under which an evacuation is required.

Additionally, site location and meteorological conditions (i.e., wind speed and direction) may dictate

evacuation routes. As a result, assembly points will be selected and communicated to the workers

relative to the site location where work is being performed. Evacuation should always take place in an

upwind direction from the site.

Severe weather evacuation will be to a place of shelter determined before project start. The LM Contact

– Mr. Tom Blackman will identify severe weather shelters that can be accessed.

Evacuation Routes

To support emergency response access the emergency routes will be kept clear of staged or parked

equipment.

2.5 EMERGENCY CONTACTS

Prior to initiating field activities, personnel will be thoroughly briefed on the emergency procedures to be

followed in the event of an accident. Table 2-1 provides a list of emergency contacts and their associated

telephone numbers. This table must be posted where it is readily available to site personnel. Facility

maps should also be posted showing potential evacuation routes and designated meeting areas.

Any pertinent information regarding allergies to medications or other special conditions will be provided to

medical services personnel. This information is listed on Medical Data Sheets filed onsite (See

Attachment IV). If an exposure to hazardous materials has occurred, provide hazard information from

Table 6-1 to medical service personnel. The LM Project Lead shall be contacted immediately in the event of a fatal or serious injury, and

unpermitted environmental release, or any ESH incident that is likely to generate significant publicity or an

adverse situation for LM. Detailed requirements are describe in Section 1.15 of the LM Handbook

(Attachment I).

In the event of an emergency not requiring 9-1-1, LMC facility personnel should be contacted in the order

presented on Table 2-1.

2.7 EMERGENCY ALERTING AND ACTION/RESPONSE PROCEDURES

Tetra Tech personnel will be working in close proximity to each other at LM MRC (LM/MRC). As a result,

hand signals, voice commands, line of site communication, and cell phones will comprise the methods to

be employed to alert site personnel of an emergency.

If an emergency incident occurs, the following procedures are to be initiated:

Alert site personnel of the incident.

Initiate incipient response measures for fire, spill, injury (first aid).

If these initial measures fail to control the incident, the FOL and/or the SSO will contact

emergency services.

o Dial 911 and call other pertinent emergency contacts listed in Table 2-1 and report the

incident.

o Give the emergency operator the location of the emergency, the type of emergency, the

number of injured, and a brief description of the incident.

o Stay on the phone and follow the instructions given by the operator.

o The operator will then notify and dispatch the proper emergency response agencies.

Site personnel shall report to the designated refuge point where the FOL will account for all personnel

Once site personnel are accounted for the FOL and/or the SSO may disperse personnel to control

access points to provide perimeter security until emergency services arrive.

Describe to the FOL (FOL will serve as the Incident Coordinator) pertinent incident details.

2.8 PERSONAL PROTECTIVE EQUIPMENT (PPE) AND EMERGENCY EQUIPMENT

A first-aid kit, eye wash units (or bottles of disposable eyewash solution) and fire extinguishers

(strategically placed) will be maintained on-site and shall be immediately available for use in the event of

an emergency. Each truck transporting soils will have a portable extinguisher; each piece of excavating

equipment will have a portable extinguisher (at least 2A:10B:C). This equipment will be located in the

field office (if provided) as well as in each site vehicle. All first aid kits should be supplied with equipment

to protect against bloodborne pathogens will also be available on site. Personnel identified within the field

crew with bloodborne pathogen and first-aid training will be the only personnel permitted to offer first-aid

assistance.

The following represents the minimum PPE for all Block E activities:

Hard hat meeting the ANSI Z89.1.

Safety eyewear meeting ANSI Z87.1 requirements.



Field Attire – Long sleeves and long pants. If performing intrusive work (slab sampling soil

excavation) field personnel will wear a Saranex full body suit or coverall and nitrile gloves

Steel-toed work boots which meet the ANSI Z41 Standard shall be provided when impact and/or

compression hazards exist.

Variations in this level of protection will be identified on the Safe Work Permit issued for that task.

Reduction in levels of protection will require SSO approval.

Hearing protection must be worn in all areas posted to indicate high noise level or where employees

are exposed to noise levels in excess of the OSHA action level (85 dBA over an 8-hour time-weighted

average or a dose of fifty percent). During this filed work

Protective clothing such as suits, aprons, boots or gloves shall be worn where there is a hazard to the

body through dermal contact with chemicals, dusts, heat or other harmful agents or conditions.

All personal protective clothing and equipment will be used and approved as detailed in Section 3.1 of the

LM Handbook (Attachment I).

Tetra Tech maintains a PPE program. The level of protection required at each active job site will be

addressed in this SSHASP and also provided on the Safe Work Permit based on the work activity,

associated site hazards and the contaminants of concern. Conditions at the site may change; therefore,

the on-going level of personal protection will be evaluated using criteria described in Section 7.2. Any

change in the level of protection will be approved by the PHSO and documented by the SSO on Safe

Work Permits and in the daily log or Daily Activities Record.

The PPE elements identified represent those available to respond to an emergency incident.

2.8.1 Emergency Equipment

The following equipment will be maintained on-site and be immediately accessible to support incidental

response measures:



2.8.1.1 First Aid Kit

The SSO will determine the number of kits necessary based on the number of segregated operations. At

least one first-aid kit will be centrally maintained for every twenty-five employees/personnel. If a person

has to travel greater than 500-feet to obtain a first-aid kit an additional kit will be required.

2.8.1.2 Eye Wash Units

The SSO will determine the number of units necessary based on the operations. Currently, at a minimum

eye wash units will be required during storm drain cleaning operations due to water pressure involved in

the cleaning process.

As indicated before this will be determined on a case by case scenario and identified in the SSHASP

based on the nature of the task.

2.8.1.3 Fire Extinguishers

A minimum of one fire extinguisher will be maintained at project operations and be immediately available

for use in the event of an emergency. Based on the initial hazard assessment the PHSO will also identify

the number and placement of fire extinguishers. Again as above, the SSO will make a determination if

additional units are required based on activities requiring this type of support. A Type ABC fire

extinguisher must be maintained onsite and on associated motorized equipment. Fuel containers will not

be stored within 10’ of the unit motor. Fuel will be stored only in appropriate UL approved safety

containers with contents clearly labeled.

2.8.1.4 Spill Prevention Equipment

General spill prevention items that will be maintained onsite to respond to any spill would include the

following:

Shovel/rake/broom

55-gallon, unused, DOT drum UN 1A2

Adsorbent material (such as kitty litter or oil-dry)

PPE

Nitrile outer gloves

Splash Shield

Impermeable over-boots

Rain suit or impermeable apron

The SSHASP will identify site-specific materials based on the nature of the task to be performed.



2.8.2 Levels of Protection

The individual components of clothing and other protective equipment must be assembled to protect the

worker from chemical hazards and to minimize the hazards and drawbacks of the PPE. OSHA has

established four basic levels of PPE based primarily on respiratory protection and secondarily on skin

protection. These levels are described in Appendix B to 29 CFR 19 10.120. It is expected that the

majority of investigation-related work at the eight sites will entail a modified Level D PPE, with Level C or

B being available if required during confined space entry.

The majority of the work is anticipated to be in a Level D protection. This is contingent on site specific

information (contaminant levels and monitoring instrument results). Level D as anticipated for this project

would consist of:

Hard hat.

Safety glasses equipped with side shields or wrap around.

Standard field attire to meet ambient conditions (long sleeve shirt and full length pants).

Safety shoes.

Standard work gloves.

High Visibility Vest to increase visual recognition when working near traffic patterns.

Hearing protection NRR of 25dB will be available for use during high noise operations.

Modifications to this level of protection, includes provisions when functions present the possibility of

splash or incidental contact with site contaminant:

Tyvek, Tychem or Rainsuits for contact with soils or sediments in the storm drains and during the

decontamination process.

Face shield

Chemical splash safety goggles

Chemical resistant boot covers

Chemical resistant gloves – nitrile outer gloves layered as necessary over nitrile surgeons gloves.

During cold weather a cotton glove line is recommended to absorb the sweat and provide warmth.

Gloves get changed out each time personnel exit the exclusion zone.

The SSO will conduct site-specific monitoring to evaluate conditions that may allow the refinement of the

level of PPE required at a site. As conditions at the site may change, the on-going level of personal

protection will be evaluated on a regular basis to determine the need for change and the extent or level of

that change. All changes made to the defined levels of protection will be made through the PHSO and

PM. For additional information concerning selection of PPE, see Section 8.0 in the HSGM.



2.9 HAZARDOUS WASTE OPERATIONS AND EMERGENCY RESPONSE

Tetra Tech and/or subcontractor personnel will perform periodic work area inspections to determine the

effectiveness of the site safety and health plan and to identify and correct unsafe conditions in the work

area. These inspections shall be documented by the SSO and available to LM upon request for review.

The requirements and regulations described in Section 3.20 of the LM Handbook (Attachment I) will be

adhered to.

2.10 DECONTAMINATION PROCEDURES / EMERGENCY MEDICAL TREATMENT

During any site evacuation, decontamination procedures will be performed only if doing so does not

further jeopardize the welfare of site workers. Decontamination will be postponed if the incident warrants

immediate evacuation. However, it is unlikely that an evacuation would occur which would require

workers to evacuate the site without first performing the necessary decontamination procedures. In

addition, given the anticipated levels of protection simple removal of these PPE items is not considered

problematic. They will be removed and the attending facility will be notified. The selection of the medical

provider is incumbent on available resources and ability to man a full decontamination unit.

Tetra Tech personnel will perform rescue operations from emergency situations and may provide initial

medical support for injury/illnesses requiring only "Basic First-Aid" level support and Cardio Pulmonary

Resuscitation (CPR), and only within the limits of training obtained by site personnel.

2.10.1 Emergency Medical Treatment

Basic First-Aid is considered treatment that can be rendered by a trained first aid provider at the injury

location and not requiring follow-up treatment or examination by a physician (for example; minor cuts,

bruises, stings, scrapes, and burns). At least one site personnel is trained in First-Aid/CPR Bloodborne

Pathogen. Medical attention above First-Aid level support will require assistance from the designated

emergency response agencies. Attachment II provides the procedure to follow when reporting an

injury/illness, and the form to be used for this purpose

Emergency medical treatment will be initiated under the following guarded restrictions:

Scene safety – Evaluate the scene make sure it is safe to enter and provide assistance.

Notify the FOL and/or the SSO of the incident.

Take the necessary precautions to prevent direct contamination with the injured person’s body fluids.

Recommended practices include, but not limited to the following:



Use surgeons gloves when handling cuts, abrasions, bites, punctures, etc. or any part of the

injured person.

Use safety glasses and surgeons masks when necessary, if there is the potential for uncontrolled

spread of body fluids.

In situations where contact occurs with non-intact skin, eyes, mouth, or other mucous membranes

should be immediately reported to the PHSO.

Should Cardio-Pulmonary Resuscitation (CPR) be required, use a CPR Micro-Shield mouthpiece

when administering CPR to prevent contact with the injured party’s body fluids.

To engage these protective measures the FOL or the SSO shall insure that these items are part of their

first-aid kit.

2.11 INJURY/ILLNESS REPORTING

If any Tetra Tech or subcontractor personnel are injured or develop an illness as a result of working on

site, the Tetra Tech “Incident Report Procedure” (Attachment II) must be followed. Following this

procedure is necessary for documenting of the information obtained at the time of the incident.

Any pertinent information regarding allergies to medications or other special conditions will be provided to

medical services personnel. This information is listed on Medical Data Sheets filed onsite. If an exposure

to hazardous materials has occurred, provide information on the chemical, physical, and toxicological

properties of the subject chemical(s) to medical service personnel. The following represents reporting

protocol:

Secure emergency situation, care for any injured personnel, secure the site. Send one person to the

hospital with the MHASP/SSHASP with the injured person. This person will notify Work Care.

Notify the PM, HSM of the incident, Begin the onsite investigation through the completion of the

applicable sections of Attachment I and II.

Based on the directions received from the PM, the PM can contact the POC of the facility or the FOL

may do so upon receiving the approval from the PM.

DO NOT speculate, complete applicable sections of Attachment I and II to define cause and effect.

The Tetra Tech PM will be notified and will contact the LMC personnel in the order presented in Table 2-1

in the event of a fatality, injury, environmental release (spill), near-miss incident, or an ESH incident. A

written report of the incident/injury/spill and corrective action(s) must be submitted to LMC personnel



within one (1) day of the incident. Injuries that may require medical care also have to be reported within

24-hours to Human Resources.

2.11.1 TOTAL Incident Reporting System

TOTAL is Tetra Tech’s new online incident reporting system. Site employees can use TOTAL to directly

report health and safety incidents, notify key personnel, and initiate the process for properly investigating

and addressing the causes of incidents, including near-miss events. An incident is considered any

unplanned event. It may include several types of near misses, events where no loss was incurred, or

incidents that resulted in injuries or illness, property or equipment damage, chemical spills, fires, or

damage to motor vehicles.

TOTAL looks like the incident reporting form in Attachment II. TOTAL is an intuitive system that will guide

you through the necessary steps to report an incident within 24 hours of its occurrence. Behind the

scenes, TOTAL is a powerful tool for H&S professionals, and will help Tetra Tech to better track incidents,

analyze root causes, implement corrective action plans, and share lessons learned. The ultimate result is

a more safe and healthy working environment for us all.

TOTAL is maintained on the Tetra Tech Intranet site at https://my.tetratech.com/

Once on the “My Tetratech” site, TOTAL can be found under the Health and Safety tab, Incident

Reporting section, select “Report an Incident (TOTAL)”. This will connect you directly to TOTAL.

TOTAL can also be accessed directly from the internet using the following web address:

http://totalhs.tetratech.com/

Note: When using the system outside the Tetra Tech intranet system or when operating in a wireless

mode, a VPN connection will be required. The speed of the application may be affected dependent upon

outside factors such as connection, signal strength, etc. Enter the system using your network user name

and password. The user name should be in the following format - TT\nickname.lastname

Section 8.1 of the LM Handbook (Attachment I) describing the requirements of accident, injury, illness

and incident reporting will be addressed.

117-0507396 3-1 MHASP Block E Drainage System

3.0 SITE BACKGROUND

3.1 SITE HISTORY

The LMC MRC is located at 2323 Eastern Boulevard in Middle River, Maryland. The site consists of

approximately 180 acres of land and twelve main buildings. The property also includes:

Identified perimeter parking lots,

An athletic field,

Block E/Lot D (presently a vacant lot with a concrete foundation for former Building D) - Project Area,

A trailer and parts storage lot,

A vacant waterfront lot.

The site is bounded by Eastern Boulevard (Route 150) to the north, Dark Head Creek to the south, Cow

Pen Creek to the west, and Martin State Airport to the east.

Currently, LMC activities at the site are limited to facility and building management and maintenance.

There are two main tenants at the site, Middle River Aircraft Systems (MRAS) and Naval Electronics &

Surveillance Systems (NE&SS), also referred to as Vertical Launch Systems. MRAS conducts design,

manufacturing, fabrication, testing, overhaul, and repair and maintenance of aeronautical structures,

parts, and components for military and commercial applications. NE&SS conducts fabrication, assembly,

testing and support of vertical launch systems. Historically, the property has been used for aircraft and

missile launching systems design, development, and sales.

3.1.1 Block E

The current Storm Drain system at Block E consist of groups of surface water inlets (IL) or grated drains,

catch basins, manholes (MH), and underground piping that discharge to Dark Head Cove via three

outfalls: Outfall 05, Outfall 06, and Outfall 08. These outfalls are located in the southern and eastern

portions of Block E. A pre-sampling site reconnaissance in 2009 identified 34 existing inlets and

manholes that drain Block E. The Block E Storm Drain system outfalls and other components are

described below.

Outfall 05 System

The Outfall 05 storm water system is constructed of rectangular, brick and mortar inlet boxes with steel

grate covers, brick and mortar manholes with solid covers and circular concrete pipe. Pipe sizes for the

system range from 15-inches in diameter at upstream inlets IL-19 and IL-20 to 32-inches in diameter at

downstream manholes MH-3, MH-2, and MH-1. Outfall 05 has two discharge points which drain surface



water in the southern portion of Block E via a series of inlets beginning at upstream inlet IL-20. Storm

water flows westward to IL-19 where the system splits with one pipe going to MH-7, MH7a and MH-4, and

the other pipe running to IL-18. The system reconnects and continues as one pipe southwest below

Chesapeake Park Plaza with surface features IL-30 and MH-3, where it splits and runs to MH-2 and MH-1

and discharges to Dark Head Cove via the two discharge points of Outfall 05. A western extension of the

system starts at inlet IL-17 and connects to MH-4. The pipe is reported to be 12-inch diameter concrete

but it could not be verified during the 2009 field activities due to the presence of sediment and deep

standing water above the crown of the outlet pipe at IL-17. Six additional inlets and manholes comprise a

storm water system located east of Block E (Outfall 09).

Outfall 06 System


grate covers, brick and mortar manholes with solid covers, and circular concrete pipe except for

corrugated steel pipes connecting IL-10 and IL-11 and IL-11 to IL-21. Pipe sizes for the system range

from 12-inches in diameter at upstream inlets IL-10 and IL-11 to 32-inches in diameter at downstream

inlet IL-25 to Outfall 06. This system drains surface water in the northern portion of Block E drains via a

series of inlets beginning at upstream inlet IL-16 located in the north-central portion of Block E. Storm

water flows eastward to inlet IL-22, where the system continues south below the median of Chesapeake

Park Plaza at IL-9, IL-24, and IL-25 and discharges to Dark Head Cove at Outfall 06. This part of the

system also receives local storm water from the northeast corner of Block E at inlets IL-10, IL-11 and

IL-21.

Outfall 08 System


grate covers, brick and mortar manholes with solid covers, buried manholes, and circular concrete pipe.

Pipe sizes for the system range from 18-inches in diameter at upstream inlet IL-20 and IL-19 to 24-inches

in diameter from IL-1 to Outfall 08. The Outfall 08 system runs north-south and drains surface water in

the eastern portion of Block E drains via a series of inlets/pipes beginning at upstream inlet IL-7 located in

the east-central portion of Block E. Storm water flows southward to MH-10 (IL-3) then to IL-2 and IL-1.

Storm water discharges to Dark Head Cove at Outfall 08. Inlet IL-23 is connected to both IL-4 and IL-24.

Storm water entering into IL-23 may discharge to both Outfalls 06 and 08. MH-10 (IL-3) is also connected

to the storm system line located to the west at MH-9 and MH-8. Storm water has been observed flowing

in the pipe entering MH-10 (IL-3) from the west. MH-8 and MH-9 are buried below grade and are not

visible at the ground surface.

For further information on the Block E Storm Drain system sites refer to the Design Report Interim

Remedial Measures Block E Drainage System.



4.0 SCOPE OF WORK

The SSHASP addresses health and safety issues related to the Block E Storm Drain Project that will be

performed by Tetra Tech and subcontractors at LM-MRC. This project includes:

Removal of sediment and debris from the inlets and manholes with a jet/vacuum truck or by hand with

containment of solids in an open top watertight roll-off container.

Jet cleaning of the drainage pipe,removing the solids and liquids with a jet/vacuum truck and

containment in an open top watertight roll-off container and liquid placed in a fractionation (frac) tank.

Drainage pipes will be cleaned after all structures are cleaned.

Sediment and wastewater containers will be relocated as needed.

Video inspection of the drainage pipe with CCTV cameras providing verification that the pipes are

clean.

Site activities at Block E include the following:

Mobilization/demobilization activities:

IRM Construction

Pre-Construction Walkthrough

Pre-Construction and Post-Construction Land Survey

Erosion Controls Installation

Work Area Breakdown

Storm Drain System Cleaning

Repair/Replace Inlets and Manholes

Confined Space Entry

On-Site Water Treatment and Discharge

Post Construction Activities

Site Restoration

Drainage System Maintenance

Waste Management

Handling and Storage

Testing - Disposal

Decontamination

No other activities are anticipated as of the date of this SSHASP. If it becomes apparent that additional

or modified tasks must be performed beyond those listed above, the work is not to proceed until the FOL



or SSO notifies the PM and the HSM, so that any appropriate modifications to this SSHASP can first be

developed and communicated to the intended task participants.



5.0 IDENTIFYING AND COMMUNICATING TASK-SPECIFIC HAZARDS AND SAFE WORK PRACTICES

The purpose of this section is to identify the anticipated hazards and appropriate hazard

prevention/hazard control measures that are to be observed for each planned task or operation. These

topics have been summarized for each planned task through the use of task-specific Safe Work Permits

(SWPs), which are to be reviewed in the field by the SSO with all task participants prior to initiating any

task when the permits are issued. Additionally, potential hazard and hazard control matters that are

relevant but are not necessarily task-specific are addressed it the following portions of this section.

Section 6.0 presents additional information on hazard anticipation, recognition, and control relevant to the

planned field activities.

In the event of situation, not requiring calling 9-1-1, LM facility personnel will be contacted in the order

presented on Table 2-1.

5.1 GENERAL SAFE WORK PRACTICES

In addition to the task-specific work practices and restrictions identified in the SWPs (Attachment V) the

following general safe work practices are to be followed when conducting work on-site.

Eating, drinking, chewing gum or tobacco, taking medication, or smoking in contaminated or

potentially contaminated areas or where the possibility for the transfer of contamination exists is

prohibited.

Lead is one of the primary contaminants of concern. Lead is a bioaccumulative substance. In this

scenario, the primary route of exposure is often hand to mouth activities and poor work hygiene

practices.

Wash hands and face thoroughly upon leaving a contaminated or suspected contaminated area.

It is recommended that D-Lead hand sanitizer be used for washing hands and face as it binds the

lead.

In addition, D-lead wipes should be used for hands and face when a potable water source is not

available of for wiping down hard surfaces (such as the excavator controls).

Site control provisions will be used to isolate contaminated materials.

These include construction entrances, erosion and sediment control and berms to isolate the

spread of contaminants.



However, when in contaminated areas, avoid contact with potentially contaminated substances

including puddles, pools, mud, or other such areas.

Avoid, kneeling on the ground or leaning or sitting on equipment. Keep monitoring equipment away

from potentially contaminated surfaces.

Minimize the number of personnel and equipment in contaminated areas (such as the exclusion

zone). Non-essential vehicles and equipment should remain within the support zone.

Establish appropriate safety zones including support, contamination reduction, and exclusion zones.

Establish appropriate decontamination procedures for leaving the site.

Plan and mark entrance, exit, and emergency evacuation routes.

Rehearse unfamiliar operations prior to implementation.

Buddies should maintain visual contact with each other and with other on-site team members by

remaining in close proximity to assist each other in case of emergency.

Immediately report all injuries, illnesses, and unsafe conditions, practices, and equipment to the SSO.

Observe co-workers for signs of toxic exposure and heat or cold stress.

Inform co-workers of potential symptoms of illness, such as headaches, dizziness, nausea, or

blurred vision.

There are a number of safe work practice categories provided in Section 13.0 of the Tetra Tech HSGM

that maybe utilized in constructing the SSHASP as well as training tools for Tail Gate Training Sessions. It

is recommended that FOLs, SSOs, take advantage of these to educate site personnel.

5.2 HAND AND POWER TOOL SAFE WORK PRACTICES

There will be a number of hand tools employed to construct barriers (earthen berms, silt fences) and site

control boundaries. The following safe work practices will be employed during hand and power tool usage

to prevent injury from faulty tools or improper practices:



All hand and power tools will be maintained in a safe condition. This includes shovel or hammer

handles; outer insulating casing (electrical tools); guards will be in place covering high temperature or

rotating apparatus. All hand and power tools will be inspected before use to ensure structural integrity

and guarding is in place where applicable.

Electrical power tools shall be grounded or double insulated with proper assured equipment

grounding inspections or Ground Fault Circuit Interrupter (GFCI) circuit protection provided. The GFCI

pigtail will be used at all electrical connection points. The GFCIs will be tested and the test

documented weekly. All electrical power tools will:

Not be used in wet or damp locations unless otherwise approved for such activity.

Not be lowered and raised by their cords.

Use spider boxes when multiple plugs are required.

Examine cords and wires for frays and/or damage in the insulation.

Pneumatic power tools shall be secured to the hose or whip by some positive means to secure an

accidental released line from falling.

Only properly trained Contractor employees shall operate power-actuated tools.

All grinding machines shall conform to OSHA and ANSI requirements. This includes:

All grinders will be inspected before use.

All grinding wheels will be rung before installation.

All portable grinders will be equipped with an 180˚ guard and adjusted properly to contain any

grinding wheel components released during grinding.

Hand and power tool use procedures are detailed in Section 3.16 of the LM handbook and will be

followed.

5.3 HOUSEKEEPING

Housekeeping procedures described in Section 5 of the LM Handbook (Attachment I) will be addressed

and the following housekeeping practices will be employed during this field effort:

Ensure discharge permits and/or Stormwater Pollution Prevention Plans (if applicable) are available

at the project job site.



Tetra Tech and/or subcontractor personnel will clean up its respective work area(s) and maintain

work areas free from all slip, trip, and fall hazards at all times.

Debris shall be kept cleared from work areas, passageways, stairs, and in and around buildings or

other structures. The work area must be left free from accumulation of waste and rubbish at the end

of each work shift.

Combustible scrap and debris shall be removed at regular intervals during the course of work. Safe

means shall be provided to facilitate such removal.

At the end of each working day and/or the conclusion of work being performed, the work area will be

restored to the same degree of neatness as when work commenced.

Tetra Tech and/or subcontractor will furnish necessary equipment and/or receptacles to remove

waste and rubbish from the job site unless otherwise specified by LM.

5.4 EXCAVATION – GENERAL SAFE WORK PRACTICES

5.4.1 Before Excavation Activities

Identify underground utilities, buried structures, and aboveground utility lines before drilling. Tetra

Tech, Inc. personnel will use the Utility Locating and Excavation Clearance Standard Operating

Procedure provided in the Tetra Tech HSGM, Section 7.0, as well as an Approved contractor and

coordination with LM/MRC facilities to identify all subsurface utilities. Section 5.7 and the LM/MRC

Handbook defines requirements to be executed prior to intrusive activities.

All excavation boundaries and roads leading into the area will be demarcated with appropriate

signage warning of construction activities in progress. Signs shall be used also for informational

purposes as well to direct personnel, as well as directing PPE requirements.

All heavy equipment will be subjected to an equipment inspection, upon arrival on-site and prior to

leaving. This inspection will be recorded on the Equipment Inspection Checklist provided in

Attachment VI of this SSHASP.

Establish traffic patterns for foot and small vehicular traffic out of the pattern for heavy equipment.

All traffic patterns for heavy equipment will be constructed to maintain traffic flow a minimum of 5-feet

from unsupported walls regardless of the depth of the excavation (excavation boundaries)



Note: The standard (29 CFR 1926 Subpart P) stipulates 2 feet distance from unsupported walls for

resource staging. However, a maintenance distance of 5-feet will be maintained until soil

classification is complete supporting a closer distance. This distance has been selected based on the

intended depth of the excavation.

Excavation along thoroughfares will require the use of signage, barricades and flag-persons for

alteration of traffic patterns, as necessary. A modification in traffic plan will be issued in accordance

with Department of Transportation (DOT) requirements for Manual on Uniform Traffic Control Devices

(MUTCD).

Anytime environmental investigation or construction remediation will impact traffic flow pattern, a

Traffic Control Plan (TCP) must be submitted to ensure the safety of the workers as well as

efficient movement of traffic.

Drawings will be provided defining elements including but not limited to:

Definition of the work space, buffer zone, placement of Caution Signs within the Advanced

Warning area and Warning Signs in the Taper area, as well as control points and speed limits.

Taper areas as well as detours will be defined in the TCP.

OSHA has adopted Part VI Standards and Guides for Traffic Control for Street and Highway

Construction and Maintenance Utility and Incident Management Operations. These guidelines will

be used to construct the TCP.

Unless weight scales are used the operator loading trucks will need to calculate load limits based on

the types of materials and level of saturation.

Saturated or wet earth will weigh approximately 100 pounds per cubic foot or 2700 pounds per cubic

yard (e.g. a 24-ton dump truck will take approximately 15 one-yard buckets before it is overloaded).

It is critical not to overload the trucks as they have to move over public roads and property. This is a

public safety and structural (roadway) restriction.

The ground personnel will be provided with reflective vests to increase visibility and based on the

traffic level carry air horns to signal heavy equipment during operation.

The loaded trucks leaving the site will be evaluated by the FOL or the SSO or designee using the Load

Inspection Report provided in Attachment VI.



5.4.2 During Excavation Activities

Ground activities shall be supported with the use of a designated ground spotter to control the actions

of the heavy equipment.

During operations, the operators are to follow only instructions as provided by the ground spotter

unless another individual is otherwise authorized.

The Ground Spotter must not place themselves between pieces of operating equipment or trucks

and/or immovable objects.

Due to the potential for entrapment and crushing, operators and truck drivers will be informed of the

necessity to assist each other in tracking and identifying the location of ground personnel in the work

area.

All excavations, regardless of depth, shall be constructed in accordance with OSHA regulations.

Where necessary sloping or benching will be utilized to maintain excavation wall stability.

No one is permitted to enter any unsupported excavation. All confirmation sampling will be done from

the excavator bucket or using extended tools.

Soil media samples collected from the excavator bucket will be conducted in the following manner:

Signal the operator regarding you intent to approach. Always do so from the front in plain view.

The operator will collected the bucket from the directed location and depth swing from the

location and set the bucket on flat and stable ground.

The operator will disengage controls and signal the sampler it is safe to approach.

The sampler will collect their sample and move from the swing pattern of the excavator and signal

the operator it is safe to re-engage the controls.

At this point the excavation work may continue.

5.4.3 After Excavation Activities

Open and unattended excavations shall be properly secured during non-working hours.

Safety fence shall demarcate excavation boundaries along traffic thoroughfares.

Where necessary, low intensity lights will be placed along the boundaries.



The Operator will ensure ramps are cut in where possible to allow escape should someone

accidentally or through purpose violate site control protocol and end up in the excavation.

Where ramps are not possible the FOL and/or the SSO shall place ladders and secure them in the

excavation to support emergency escape.

5.4 CONFINED SPACE ENTRY

The nature of hazards for confined space entry require that the FOL/SHSO:

Make sure participants are trained to the levels appropriate to their assigned duties.

Verify that participants are medically qualified to perform assigned duties.

Erect barriers to control traffic near the space as well as unauthorized entrance into the space.

Review the completed Confined Space Entry Permit with the Entry Team, including activities, roles,

and responsibilities, prior to entry.

Establish emergency rescue provisions with a rescue provider:

Make sure they can make it to the space within a specified time limit (4 minutes or less)

Review the planned activities and the rescue type and restriction should it be needed

Inspect the equipment to be used in the space to insure its operational status.

Verify that air quality within the space is acceptable for entry.

Check to insure that the Entry Permit is complete.

Post the completed Entry Permit at the confined space entrance.

Continue atmospheric testing during entry at regular intervals.

Physically survey the entire space prior to the commencement of planned activities to insure that

potential hazards, or situations, and/or conditions that could predispose field crews to emergency

conditions have been addressed.



Insure that lighting is sufficient to illuminate the space, work area, and task to be conducted.

Log personnel entering and exiting the space.

Monitor conditions outside that could impact the entrants inside the space.

When entry is complete, remove the equipment used for the entry.

Notify rescue services that the operation is completed.

Secure the space.

Cancel the permit.

Review the confined space operation with the Entry Team. If problems have been encountered,

document problems and submit suggestions to the TtNUS HSM.

The Completed Confined Space Entry Permit and the associated documents must be forwarded to

the HSM (M. Soltis) upon completion of the entry.

The confined space entry will be conducted in accordance with Attachment III. Safe work practices are

addressed in that attachment.

5.5 DRAIN CLEANING SAFETY PROCEDURES

The intent of Storm Drain line cleaning is to remove ALL foreign materials from the lines prior to televising

the pipe in order to provide a clear, unobstructed view of the entire pipe. The success of the work will

depend a great deal on the cleanliness of the lines. All high-velocity Drain cleaning equipment shall be

constructed for ease and safety of operation. The equipment shall have a selection of high-velocity

nozzles. The nozzles shall be capable of producing a scouring action from 15 to 45 degrees, in all size

lines designated to be cleaned. Every precaution will be taken to avoid damage during pipe cleaning

operations.

When hydraulically propelled cleaning tools are used precautions shall be taken to ensure that the water

head pressure does not damage or cause flooding of public or private property being served by the Storm

Drain. Various cutter tips may need to be used depending upon site specific conditions. All site personnel



will adhere to the Confined Space Entry Policy and the OSHA Confined Space Entry Regulations.

Removal Debris such as dirt, sand, rocks, grease, and other solid or semisolid material resulting from

the cleaning operation shall be removed at the downstream structure of the section being

cleaned. All materials will be disposed of properly when removed from the storm

Drain in accordance with all applicable laws and regulations.

Safety measures and procedure in using water jets for Storm Drain cleaning:

Equipments should be checked before using. Be sure it is safe to use and with no signs of damage.

Assess the working area.

Know what causes the blockage.

If working on public places, insure that people are at a safe distance.

If it is safe to proceed, connect the water jet to a water supply

Choose what type of nozzle to use.

See to it that the nozzle is securely connected to the lance.

5.6 COLLECTION OF WATER AND SEDIMENT FOR DISPOSAL

Field teams will refer to the Waste Management Plan (WMP) for the site to detail the procedures for

waste profiling, transportation, and disposal.

5.7 LM MINIMUM REQUIREMENTS FOR INTRUSIVE FIELDWORK WORK PLANS

5.7.1 Purpose

The purpose of these requirements is to prevent damage to subsurface and overhead utilities and

structures and unexpected chemical releases during ground disturbance activities such as excavation,

trenching, Storm Drain repair, grading or other similar operations.

5.7.2 Scope

These are the minimum requirements for subsurface clearance activities, which must be followed prior to

and during ground disturbance activities at any LM remediation project sites. Even after completing the

subsurface clearance activities identified in this procedure, all ground disturbance activities shall proceed

with caution.

These include requirements on implementing in situ chemical injection programs, on managing significant

field changes in field work plans and worksite housekeeping.



The LM Project Lead (PL), the managing contractor, and the performing contractor will be responsible for

fulfilling the objectives of this document by ensuring that these requirements are carried out by the

performing contractor's employees, sub-contractors and their employees and any other persons involved

in the intrusive activity. The work requirements outlined below shall be incorporated into the work plan.

5.7.3 Work Requirements

5.7.3.1 General

The performing contractor’s project manager and the supervisor of the intrusive field work subcontractor

must review the LM Corporate Staff Procedure EO-28 Digging Projects and the Risk Handling Checklist in

Attachment VII and VIII, and complete Dig Permit and Invasive Fieldwork Clearance and Authorization

Form found in Attachments IX and X. Requirements and questions within the Risk Handling Checklist

including identification of potential failure modes and hazards, traffic control, and excavation requirements

shall be addressed in the work plan. In addition to the provisions of CS-28, relevant state, local and

facility requirements must be identified in the work plan and in place before initiating any work. CS-28, the

Risk Handling Checklist and the Dig Permit are included in Attachment VIII and IX of the MHASP.

The permit and the checklist shall be completed and approved by the PL before initiating any ground

disturbance activities. The PL shall forward these items to the Environment, Safety and Health (ESH)

professional, the performing contractor responsible for oversight, and the facility manager, as necessary,

for their review.

5.7.3.2 Utility and Underground Structure Clearance

A utility and underground structure location survey which includes, but is not limited to records research,

consultation with site facilities personnel, site inspection to locate physical evidence of underground or

overhead utilities or structures and geophysical or other appropriate remote sensing techniques must be

performed by a qualified utility location firm at least two weeks prior to initiating any intrusive activities.

The survey shall include the appropriate equipment necessary to detect buried foundations and slabs,

piping, direct-bury cables and other buried conduits and structures using the technologies appropriate to

the anticipated utilities such as electromagnetic detector; ground penetrating radar; acoustic plastic pipe

locator; probe, beacon, or trace wire; or cesium magnetometer. A table summarizing applicability of

technologies for detecting various utilities is presented in Attachment XI.



Because undocumented or inactive utilities can result in problems as severe as or more severe than

documented utilities, utility location work must include, at minimum, ground penetrating radar as a

screening tool to identify objects that may not be documented on utility record plans and other records. The utility location/survey firm operators shall have at least 2 years of experience on industrial sites and

preferably direct experience on the site under review. The utility survey firm shall be approved by the LM

PL.

In addition to the utility survey, the state or other legally-mandated utility clearing organization (“Dig Safe,”

“U-Dig” or other such organization) having jurisdiction over the region in which the work is to occur, shall

be notified within the time period required by that organization, state and local regulations. Even if all of

the work is conducted entirely on LM or other private property, the utility clearing organization shall be

contacted.

All aboveground indicators of subsurface and overhead utilities/services that may be leading to or from

buildings and structures within the planned intrusive work area must be located and marked out in the

field. Locations of utilities and structures detected by remote sensing equipment shall also be marked out

in the field. Public utility mark-outs by for all exterior locations must be identified within required time

period. Physical evidence of underground or overhead utilities may include, but is not limited to lights,

signs, telephone systems, drains, electrical junction boxes, manhole covers, valve boxes, hand holes,

pavement patching or other evidence of prior excavations, and natural gas meters.

The contractor shall make all efforts to avoid known or observed utilities in planning the work. If, however,

subsurface structures are known or observed by geophysical survey within five feet of the work area and

the work area cannot be moved, the performing contractor and/or its subcontractor shall carefully

excavate to within two vertical feet of the expected top of the utility, then hand dig, air lance or otherwise

gently remove the remaining soil to expose the utility. Additional precautions shall be described in the

work plan if the intrusive work is to be performed in frozen soils.

The performing contractor must witness the utility clearance work to verify that the expected scope is

performed and be available to work with the utility location contractor to answer questions and facilitate

additional research or discussions with site facilities personnel.

The utility clearance contractor’s report must include details concerning the methods used to locate

utilities and documentation of how specific utilities were located in plan and depth, including a copy of

instrument output when instruments producing output are used. It is not sufficient for the report to merely



state that the utilities on the site plan were verified or that no utilities were found without providing

supporting documentation.



6.0 HAZARD ASSESSMENT AND CONTROLS

This section provides reference information regarding the chemical and physical hazards which may be

associated with activities that are to be conducted as part of the scope of work.

times per day

6.1.1 Metals

The physical effects of poisoning from the heavy metals tend to be a very slow process and occur over a

long period of continued exposure to the source of the toxic metal. The physical symptoms which are



typically induced by the presence of toxic metals in the body tend to be very vague and can include

symptoms such as persistent fatigue, the appearance of splitting and blinding headaches, the presence of

an upset stomach, disorders such as colic and even anemia in some cases. The central nervous system

is the main part of the human body likely to be affected by the presence of toxic metals. Symptoms of a

disrupted central nervous system include the appearance of muscular tremors, the development of spells

of dizziness, the presence of insomnia, the poor concentration abilities in the person and a sudden lack of

muscular coordination in the body.

6.1.1.1 Lead

Lead is a main-group element with symbol Pb. Lead is a soft, malleable poor metal, also considered to

be one of the heavy metals. Although children are primarily at risk, lead poisoning is also dangerous for

adults. Even exposure to amounts of lead too low to cause symptoms in the short term may increase the

risk of high blood pressure and mental decline in the future. Symptoms in adults may include:

Pain, numbness or tingling of the extremities

Muscular weakness

Headache

Abdominal pain

Memory loss

Mood disorders

Reduced sperm count, abnormal sperm

Miscarriage or premature birth in pregnant women

Fatigue

In general, lead has a soft ductile gray appearance. Furthermore it has no odor. So detection using

physical senses are unlikely in this scenario. During Storm Drain repair excavation of pipe, culverts and

boxes will ocurr it is unlikely that you would recognize lead in the soils unless it was a manufactured item

such as batteries or something related to a process such as paint chips and black beauty a sand blasting

grit indicating lead based paints may also be encountered.

As lead is a particulate or will be bound to particulates efforts will be directed to minimize dust evolution

through area wetting. Airborne monitoring will also be conducted to monitor total dust and particulate size.

6.1.2 Volatile Organic Compounds

Volatile organic compounds (VOCs) refers to organic chemical compounds which have significant

vapor pressures and which can affect the environment and human health. VOCs are numerous, varied,

http://en.wikipedia.org/wiki/Heavy_metal_(chemistry)�

http://en.wikipedia.org/wiki/Organic_chemicals�

http://en.wikipedia.org/wiki/Vapor_pressure�



and ubiquitous. Although VOCs include both man-made and naturally occurring chemical compounds, it

is the anthropogenic VOCs that are regulated, especially for indoors where concentrations can be

highest. VOCs are typically not acutely toxic but have chronic effects. Because the concentrations are

usually low and the symptoms slow to develop, analysis of VOCs and their effects is a demanding area.

Health effects include: Eye, nose, and throat irritation; headaches, loss of coordination, nausea; damage

to liver, kidney, and central nervous system. Some organics can cause cancer in animals; some are

suspected or known to cause cancer in humans. Key signs or symptoms associated with exposure to

VOCs include conjunctival irritation, nose and throat discomfort, headache, allergic skin reaction,

dyspnea, declines in serum cholinesterase levels, nausea, emesis, epistaxis, fatigue, dizziness.

The ability of organic chemicals to cause health effects varies greatly from those that are highly toxic, to

those with no known health effect. As with other pollutants, the extent and nature of the health effect will

depend on many factors including level of exposure and length of time exposed. Eye and respiratory tract

irritation, headaches, dizziness, visual disorders, and memory impairment are among the immediate

symptoms that some people have experienced soon after exposure to some organics. At present, not

much is known about what health effects occur from the levels of organics usually found in homes. Many

organic compounds are known to cause cancer in animals; some are suspected of causing, or are known

to cause, cancer in humans.

6.1.2.1 Benzene

Benzene is a colorless and highly flammable liquid with a sweet smell and a relatively high melting point.

Because it is a known carcinogen, its use as an additive in gasoline is now limited, but it is an important

industrial solvent and precursor in the production of drugs, plastics, synthetic rubber, and dyes. Benzene

is a natural constituent of crude oil, and may be synthesized from other compounds present in petroleum.

Benzene exposure has serious health effects. Outdoor air may contain low levels of benzene from

tobacco smoke, wood smoke, automobile service stations, the transfer of gasoline, exhaust from motor

vehicles, and industrial emissions. Vapors from products that contain benzene, such as glues, paints,

furniture wax, and detergents, can also be a source of exposure, although many of these have been

modified or reformulated since the late 1970s to eliminate or reduce the benzene content. Air around

hazardous waste sites or gas stations may contain higher levels of benzene.

The short term breathing of high levels of benzene can result in death, while low levels can cause

drowsiness, dizziness, rapid heart rate, headaches, tremors, confusion, and unconsciousness. Eating or

drinking foods containing high levels of benzene can cause vomiting, irritation of the stomach, dizziness,

sleepiness, convulsions, and death.

The major effects of benzene are chronic (long-term) exposure through the blood. Benzene damages the

bone marrow and can cause a decrease in red blood cells, leading to anemia. It can also cause

excessive bleeding and depress the immune system, increasing the chance of infection. Benzene causes

leukemia and is associated with other blood cancers and pre-cancers of the blood.

6.1.2.2 Chlorobenzene

Chlorobenzene's production and use as a chemical intermediate, solvent, and heat transfer medium may

result in its release to the environment through various waste streams. If released to air, a vapor pressure

of 12 mm Hg at 25º C indicates chlorobenzene will exist solely as a vapor in the atmosphere. Vapor-

phase chlorobenzene will be degraded in the atmosphere by reaction with photochemically-produced

hydroxyl radicals; the half-life for this reaction in air is estimated to be 21 hrs. Chlorobenzene may

volatilize from dry soil surfaces based upon its vapor pressure. If released into water, chlorobenzene may

adsorb to suspended solids and sediment. Volatilization from water surfaces is expected to be an

important fate process based upon this compound's Henry's Law constant. Estimated volatilization half-

lives for a model river and model lake are 3.4 hours and 4.3 days, respectively. Hydrolysis is not expected

to be an important environmental fate process since this compound lacks functional groups that hydrolyze

under environmental conditions. Occupational exposure to chlorobenzene may occur through inhalation

and dermal contact with this compound at workplaces where chlorobenzene is produced or used.

Monitoring data indicate that the general population may be exposed to chlorobenzene via inhalation of

ambient air, ingestion of food and drinking water, and dermal contact with this compound.

6.1.2.3 Vinyl Chloride

Vinyl chloride's production and use in the manufacture of polyvinyl chloride (PVC) and other chlorinated

compounds may result in its release to the environment through various waste streams. In acute

exposure, deaths are most often due to CNS and respiratory depression.

The primary toxic hazard is exposure to vinyl chloride monomer (VCM) gas rather than to poly vinyl

chloride (PVC) products (except during pyrolysis). There may be a long latent period between exposure

and symptom onset. The nervous system is the primary target of acute vinyl chloride exposure.

Signs and symptoms following ingestion include weakness; ataxia; inebriation; headache; fatigue;

numbness; tingling and pallor or cyanosis of the extremities; nausea; abdominal pain; GI bleeding; visual

disturbances; cardiac dysrhythmias; narcosis and death. Vinyl chloride is a severe irritant of the eyes,

skin, and mucous membranes.

6.1.2.4 Polycyclic Aromatic Hydrocarbons (PAHs)

PAHs are a group of over 100 different chemicals that are formed during the incomplete burning of coal,

oil and gas, garbage, or other organic substances like tobacco or charbroiled meat. PAHs are usually

found as a mixture containing two or more of these compounds, such as soot.

Some PAHs are manufactured. These pure PAHs usually exist as colorless, white, or pale yellow-green

solids. PAHs are found in coal tar, crude oil, creosote, and roofing tar, but a few are used in medicines or

to make dyes, plastics, and pesticides.

Exposure to polycyclic aromatic hydrocarbons usually occurs by breathing air contaminated by wild fires

or coal tar, or by eating foods that have been grilled. PAHs have been found in at least 600 of the 1,430

National Priorities List sites identified by the Environmental Protection Agency.

PAHs have the potential to cause harmful effects on the skin, body fluids, and ability to fight disease after

both short- and long-term exposure.

6.1.2.5 Poly Chlorinated Biphenyls (PCBs)

PCB related chemicals are odorless, tasteless, clear to pale-yellow, viscous liquids (highly chlorinated

mixtures are more viscous and deeper yellow). They are formed by electrophilic chlorination of biphenyl

with chlorine gas. Theoretically, 209 different PCB related chemicals are possible, although only about

130 are found in commercial PCB mixtures. PCBs have high solubilities in most organic solvents, oils,

and fats. They have high dielectric constants, very high thermal conductivity, high flash points (from 170

to 380 °C) and are chemically fairly inert, being extremely resistant to oxidation, reduction, addition,

elimination, and electrophilic substitution. The toxicity of PCBs had been known since before its first

commercial production through research done by producing companies themselves in the 1930s. The

toxicity of PCBs varies considerably among related chemicals. PCBs tend to have dioxin-like properties,

and generally are among the most toxic related chemicals. Because PCBs are almost invariably found in

complex mixtures, the concept of toxic equivalency factors (TEFs) has been developed to facilitate risk

assessment and regulatory control, where more toxic PCB related chemicals are assigned higher TEF

values. PCBs also have shown toxic and mutagenic effects by interfering with hormones in the body.

PCBs, depending on the specific congener, have been shown to both inhibit and and imitate estradiol, the

main sex hormone in females. Imitation of the estrogen compound can feed estrogen-dependent breast

cancer cells, and possibly cause other cancers, such as uterine or cervical. Inhibition of estradiol can lead

to serious developmental problems for both males and females, including sexual, skeletal, and mental

development issues.

Signs and symptoms

The most commonly observed health effects in people exposed to extremely high levels of PCBs are skin

conditions, such as chloracne and rashes, but these were known to be symptoms of acute systemic

poisoning dating back to 1922. Studies in workers exposed to PCBs have shown changes in blood and

urine that may indicate liver damage. Common symptoms included dermal and ocular lesions, irregular

menstrual cycles and lowered immune responses. Other symptoms included fatigue, headaches,

coughs, and unusual skin sores. Additionally, in children, there were reports of poor cognitive

development.

There have also been studies of the health effects of PCBs in the general population and in children of

mothers who were exposed to PCBs.

6.1.3 Inhalation

As indicated in the table above, from a worst-case scenario, COC concentrations immediately above a

captured air phase above contaminated groundwater (such as in the head space of a monitoring well)

could potentially reach concentrations that exceed the OELs. However, in regarding the results of this

data evaluation, it is important to recognize the following:

The planned work area is outdoors, with ample natural ventilation that will reduce any airborne COCs

through dilution and dispersion,

Area wetting will be employed during all excavation or dust generating activities to further minimize

mobility and hence exposure.

Real time air monitoring and air sampling will be conducted to monitor airborne particulates. As a

result of these factors, it is very unlikely that workers participating in this activity will encounter any

airborne concentrations of COCs that would represent an occupational exposure concern. To

monitor this route, real-time direct reading monitoring instruments will be used (as described in

section 7.0). This will be performed during intrusive tasks, as these tasks are the most likely to

involve encountering/releasing any COCs into the air phase.

During excavation activities the HEPA filter leading into the cab of earth moving equipment will be

monitored and changed periodically. If a periodic maintenance is provided by the rental company,

provisions for periodic change out will be identified. Contaminated filters will be disposed of with the

contaminated soil matrix.

6.1.4 Ingestion and Skin Contact

Potential exposure concerns to the COCs may also occur through ingestion, or coming into direct skin

contact. The likelihood of worker exposure concerns through these two routes are also considered very

unlikely, provided that workers follow good personal hygiene and standard good sample collection/sample

handling practices, and wear appropriate PPE as specified in this SSHASP. Examples onsite practices

that are to be observed that will protect workers from exposure via ingestion or skin contact include the

following:

No hand-to-mouth activities on site (eating, drinking, smoking, etc.)

Washing hands using D-lead wipes or hand wash upon leaving the work area and prior to performing

any hand to mouth activities.

Wearing surgeon's-style gloves whenever handling potentially-contaminated media, including

groundwater and any potential free product, sampling equipment, and sample containers.

Wiping down common surfaces with D-Lead wipes to minimize transfer.

6.2 PHYSICAL HAZARDS

The following is a list of physical hazards that may be encountered at the site or may be present during

the performance of site activities.

Subsurface hazards and contact with utilities/electrical safety

Aboveground hazards

Suspended loads

Noise

Slips, trips, and falls

Heavy lifting (strain/muscle pulls)

Vehicular and foot traffic

Heavy equipment hazards (rotating equipment, hydraulic lines, etc.)

Drum handling

Inclement weather

Heat/cold stress

Fire

Pinches and compressions

Natural hazards



Specific hazards are discussed further below, and are presented relative to each task in the task-specific

Safe Work Permits.

6.2.1 Subsurface Hazards and Contact with Underground or Overhead Utilities/Electrical Safety

Contact with energized sources can result in severe injury and even death. There are two areas of

concern with this potential hazard: contact with energized processing equipment and contact with

energized utilities including underground utilities (i.e., electrical transmission lines, gas lines, water lines,

etc.) and overhead utilities (i.e., power lines, etc.).

Use and application of the Tetra Tech Standard Operating Procedure (SOP) for Utility Locating and

Excavation Clearance found in the Tetra Tech HSGM Section 7.0 will be employed. In addition,

Enviroscan, a Utility detection services and support from LM PFI will be utilized to detect identify

subsurface utility structures.

Establishment of a suitable clearance distance (20-feet) from overhead utilities will be the primary

method to control hazards conveyed through contact with these power sources.

In addition, the electrical safety procedures stipulated in Section 3.9 of the LM Handbook and the

overhead power line safety procedures in Section 3.14 of the LM Handbook will also be followed.

Hazardous energy work is currently not authorized as part of this field effort. However, should activities

associated with lockout/tagout be required, the requirements stipulated in Section 3.5 of the LM

Handbook (Attachment I) will also be adhered to.

If after all measures have been used to avoid utility contact and damage, the following will be conducted

in the event of utility contact and/or damage.

6.2.1.1 Electrical

If contact is made, it is important not to contact the ground surface and the equipment at the same time.

Cease all operations, remain in the truck and/or excavator. Contact the SSO. The SSO will contact the

utility authority, provide security surrounding the truck and/or excavator until the power source can be de-

energized. Do not leave the excavator unless imminent danger exists. When exiting, do not make contact

with the ground and the excavator at the same time. Jump away from the excavator and any down power

sources. This is only in conditions of imminent danger. There are electrical conduit lines in the area that

run to lighting poles for the parking lot.



6.2.1.2 Natural Gas

Immediately shut down all operations; eliminate all ignition sources; contact 911 and the area contact or

authority; move to designated assembly point; conduct a head count provide area security at all approach

routes.

6.2.1.3 Plumbing (water/sanitary/storm)

There is a reported 42-inch stormwater line also in the excavation area. If struck, immediately shut down

all operations; contact the area contact or authority; provide perimeter security until the authorities arrive;

move to designated assembly point; conduct a head count.

6.2.2 Aboveground Hazards

Precautions will be exercised when moving or operating heavy equipment, or drilling in the vicinity of any

overhead electrical lines. The minimum clearance between overhead electrical lines and operating or

moving equipment will be no less than the following:

10 ft from any line ≤ 50 kV;

20 ft from any line > 50 kV but ≤ 345 kV; or

34 ft from any line > 345 kV.

Clearances, and reductions thereof, shall be in accordance with 29 CFR 1926.955. The aforementioned

clearance distances would be any point within a right angle to the mast.

When lightning is within five miles of the work site; personnel will terminate work and move into a

protected area.

6.2.2.1 Electrical Cords

Using portable electrical driven equipment the FOL/SSO will ensure:

If using electrically driven tools drills the following provisions will be necessary:

All plug in devices will be routed through a Ground Fault Circuit Interrupter (GFCI) to reduce the

potential for electrocution.

All portable power tools will be double insulated or equipped with a grounding plug.

Extension cords will be inspected for physical defects.



Extension cords from portable generator or provided power outlets will be rated for outdoor use

and will be of significant wire gage to carry intended amperage. The longer the distance the

heavier gauge of wire will be required.

Distance (feet) Gauge

Tool 10 Amps 0-25 16 Tool 15 Amps 0-25 14 Tool 10 Amps 25-50 16 Tool 15 Amps 25-50 14 Tool 10 Amps 50-75 16 Tool 15 Amps 50-75 12 Tool 10 Amps 75-100 16 Tool 15 Amps 75-100 12

When in doubt use a heavier gauge:

Extension cords will be kept from standing water.

Employees will not plug or unplug cords with wet gloves.

Portable Generators

The following are safety measures to be employed when working with portable generators:

Portable generators will not be fueled while running or the engine is still hot.

GFCIs (for units less than 5000w) will be tested each day to ensure its operational status.

Grounding will be employed when directed by the SSO as conditions dictate.

6.2.3 Suspended Loads

Suspended loads present another area of concern. Since suspended load may drop without warning,

personnel will not be permitted to walk beneath a suspended load. In addition, loads which are to be

chained, tied, or rigged shall be inspected prior to being lifted or suspended. Field personnel shall

perform the following safety checks:

Chains shall be checked for wear, cuts, kinks, and proper attachment prior to hoisting. All chains to

be used for hoisting and rigging will be measured at the initiation of the project. That way if the chains

show an increased length potential failure can be assessed. If any changes are noted contact the

PHSO for further direction.

Wire ropes and cables shall be checked for fraying, wear, kinks, and knotting prior to hoisting.

Equipment exhibiting any of the above characteristics shall be replaced prior to conducting any

hoisting activities.



In all cases, the weight of the load will be known as well as the working load limit of the hoisting

appliance to be used. Hoisting equipment must be rated for greater than two times the estimated

weight of the load. These pieces of equipment will be tagged indicating their capacity utilizing various

hitches.

Chains, straps, ropes or cables designated for securing loads during shipping shall not be used for

hoisting and rigging purposes.

Harnessing or rigging methodologies will be approved within standard industry use.

Hoisting and rigging activities greater than 50% critical lift capabilities will be evaluated by the PHSO

prior to conducting these lifts.

When extensive Hoisting and rigging activities are anticipated, the Tetra Tech Hoisting and Rigging

Program will be attached to the SSHASP. Within this program rigging inspection guidelines, requirements

for critical lifts and “Competent Person” requirements are posted.

6.2.4 Noise

Site activities may involve the use of heavy equipment such as heavy haulage equipment, excavators,

loaders, etc. Exposure to noise equal to or exceeding the OSHA 8-hour time-weighted average sound

level (85 dBA) could result in hearing loss. The SSO will ensure that appropriate hearing protection is

made available to all personnel working near sources of high intensity noise, in accordance with 29 CFR

1910.95. In addition, only personnel necessary to perform a specific function will be stationed near

excessively noisy equipment. Historical data from noise monitoring conducted during previous Tetra

Tech projects, indicates

DPT; air rotary; rotosonic: 92 to 97dBA

Pressure washers; steam cleaners: 92 to 95dBA

Heavy Equipment operations: 80 to 85dBA (Enclosed cab)

Note: However, noise levels vary depending on the type and condition of the drill rig or excavator, the

matrix of the soil or material being drilled or dug, and distance from the noise producing equipment or

reflective surfaces.

The general rule of thumb:

If a worker must raise their voice to be heard by someone standing next to them,

noise levels exceed 85 dBA and hearing protection will be required.



In all cases when Hearing protection is employed the site specific Hearing Conservation Program,

provided in the TtNUS HSGM (Section 6.0) will be completed by the SSO.

6.2.5 Slips, Trips, and Falls

During various site activities there is a potential for slip, trip, and fall hazards associated with wet, steep,

or unstable work surfaces. To minimize hazards of this nature, personnel required to work in and along

areas prone to these types of hazards will be required to exercise caution, and use appropriate

precautions (restrict access, guardrails, life lines and/or safety harnesses) and other means suitable for

the task at hand. Site activities will be performed using the buddy system.

Planned activities (all operations) associated with hazardous waste operations/site investigations may

bring field personnel into areas where this potential hazard exists

dilapidated buildings, floor openings, stairs

river banks, muddy slippery embankments, steep terrain

excavation boundaries and test pits,

uneven terrain (due to excavation); loose and shifting ground cover of landfill areas,

plastic protective cover (temporary decontamination pads)

work place clutter (entangle hoses)

Hazards of this nature and the potential consequences are magnified when you are maneuvering and

carrying equipment to these work sites.

6.2.6 Heavy Lifting

During execution of planned activities there is some potential for strains, sprains, and/or muscle pulls due

to the physical demands and nature of this site work. To avoid injury during lifting tasks personnel are to

lift with the force of the load carried by their legs and not their backs. When lifting or handling heavy

material or equipment use an appropriate number of personnel. Keep the work area free from ground

clutter to avoid unnecessary twisting or sudden movements while handling loads.

6.2.6.1 Lifting Hazards and Control Measures

This hazard becomes more predominant in the early morning hours (prior to muscles becoming limber)

and later in the day (as a result of fatigue). The following provisions shall be incorporated in order to

minimize hazards of this nature:



Use machinery, lifting assist devices (dollies) or multiple personnel for heavy lifts, where possible.

Use proper lifting techniques:

Lift with your legs, not your back; bend your knees and move as close to the load as possible,

and ensure good hand holds are obtainable. Wear gloves where necessary to improve

handholds.

Minimize the horizontal distance to the center of the lift to your center of gravity (i.e., torso).

Avoid turning and twisting when lifting, carrying, or depositing loads as the lower back is

especially vulnerable at this time.

Break lifts into steps if the vertical distance (from the start point to the placement of the lift) is

excessive.

Plan your lifts – Place heavy items on shelves between the waist and chest; lighter items on

higher shelves. Also, if the load must be carried to another location, plan and inspect the route to

ensure that slipping/tripping hazards are absent.

Periods of high frequency lifts or extended duration lifts should provide sufficient breaks to guard

against fatigue and injury.

Stretch and limber muscles prior to and after extended periods/frequent lifts.

Other considerations associated with lifting injuries and muscle strains include:

Area available to maneuver the lift – Rearrange the area, remove clutter, and minimize the

necessity of twisting and turning.

Area of the lift – Work place clutter, slippery surfaces. This aspect may magnify the hazard when

transporting sampling supplies/equipment over rough or uneven terrain.

Your overall physical condition – Report previous injuries (bad backs, etc.) on your Medical Data

Sheet; DO NOT attempt to lift items that will put you at risk; Break loads that you must carry into

smaller manageable loads. Get assistance whenever significant lifting tasks are involved.

By evaluating applicable contributing factors, planning your lifts, and incorporating feasible control

measures you can minimize the potential for injury. See Section 4.4 of the HSGM regarding additional

safe lifting practices.

6.2.7 Vehicular and Equipment Traffic

If working in or near streets or roadways, hazards associated with vehicular and equipment traffic are

likely to exist during various site activities and whenever site personnel performed work on or near

roadways. Site personnel will be instructed to maintain awareness of traffic and moving equipment when

performing site activities. When working near roadways, site personnel will wear high visibility vests. See

Section 5.4 of this SSHASP concerning safe work practices as it pertains to these activities.



Some common practices to be employed

DO NOT place obstructions along the sides of the road. These obstructions may cause employees to

move into the flow of traffic to avoid your activities or equipment.

Provide a required Free Space of Travel. Your movement may startle a motorist or an operator and

cause an accident.

Required “Free Space”: Maintain at least 6-feet of space between you and moving traffic. Where this

is not possible, use flaggers and/or signs to warn oncoming traffic of activities near or within the travel

lanes.

Face Traffic: Whenever feasible, if you must move within the 6-feet of required space, or into traffic

attempt to face moving traffic at all times. Always leave yourself an escape route.

Do not rely on the operator’s visibility, judgment, or ability. Make eye contact with the driver or

operator. Carefully and deliberately use hand signals so they will not startle or confuse motorists or

operators that maybe mistaken for a flagger’s or ground spotters direction before moving into traffic.

Move Deliberately: Do not make sudden movements that might confuse a motorist or an operator.

Avoid where possible interrupting Traffic Flow: Minimize crossing traffic lanes.

Rubbernecking: People can’t stand it they have to look to see what is going on, what you are doing.

As a result many fender benders occur within work areas. Where possible move traffic through the

work area but keep them separated to the extent possible that they do not collide with the car in front

of them.

Control speed through the work area.

6.2.8 Heavy Equipment Hazards

Ensure that workers are thoroughly trained and competent to perform their assigned task with the

equipment used in investigation. Ensure that back-up alarms are functional on equipment. Heavy

equipment will be subjected to an equipment inspection, upon arrival on-site and prior to leaving. This

inspection will be recorded on the Equipment Inspection Checklist provided in Attachment VI of this

SSHASP. The equipment operators and on-site Supervisors responsible for the equipment are to ensure

that the Equipment Inspection Checklist has been reviewed and completed, and that all moving or parts

exhibiting elevated temperatures are guarded if such parts are exposed. Check/test all emergency stop

controls. Use escort vehicles with flashing lights to warn and control local traffic when moving large

equipment to support area.

Only trained and authorized workers may operate heavy equipment, industrial vehicles and/or cranes. All

manufacturer’s specifications and limitations will be adhered to.



In addition, the heavy equipment, industrial vehicle, and crane operation safety procedures stipulated in

Section 3.13 of the LM Handbook and will be followed.

Working with large motor vehicles and heavy equipment poses unique hazards. Injuries can result from

malfunctioning equipment or improper operation. Personnel will receive regular reminders to avoid being

injured by heavy equipment and to be aware of the potential for failing equipment. Drill rig clamps and

ropes must be inspected in accordance with 29 CFR 1926.251. Motor vehicles and heavy equipment

design and operation will be according to 29 CFR 1926.600 through 1926.602. In particular, the following

precautions will be used to help prevent injuries and accidents:

Brakes, hydraulic lines, light signals, fire extinguisher, fluid levels, steering, tires, horn, and other

safety devices will be checked at the beginning of each week or ten-day work period.

Drill rigs or other large equipment will not be backed up unless equipped with a reverse signal alarm,

audible above the surrounding noise level, backup warning lights or the vehicle is backed up only

when an observer signals it is safe to do so.

Motor vehicle cabs will be kept free of all non-essential items and all loose items including equipment

and/or samples will be secured.

The parking brake will be set before shutting off any vehicle.

Wearing of seat belts is mandatory.

During periods of rain, fog, or other adverse weather conditions, the use of headlights is mandatory.

All posted traffic signs and directions from flagmen will be observed.

Personnel will not place themselves between operating equipment and immovable objects.

Personnel will wear High Visibility vests to increase visual recognition.

Efforts will be directed to minimize the number of personnel within an area. If you don’t need to be

there because of your job function then remove yourself.

These items have been consolidated into an Equipment Inspection Checklist provided in Attachment VI.

Heavy equipment operators have a limited field of vision and therefore may not be aware that someone is

near the equipment being operated. While heavy equipment is required to be equipped with warning

devices such as back-up alarms, and the operator is required to operate with caution, it is incumbent

upon personnel in the area to maintain sufficient distance from the equipment. For example, a sufficient

distance is beyond the reach of a backhoe turning a full 360 degrees with its bucket and boom fully

extended + 10-feet. It is also incumbent upon personnel in the area to ensure that they have made eye

contact with the operator prior to moving within the reach of the backhoe or other mechanical equipment.

The operator must cease operations and rest the bucket (or other extension) on the ground before



personnel approach. Caution will be exercised at all times. NEVER place yourself between operating

heavy equipment and immovable objects due to the potential for crushing injuries and death.

6.2.9 Drum/Container Handling/Staging Areas

Drum handling will fall into two separate categories. The first is handling Investigative Derived Waste

(IDW) drums or drums we have filled with water or soils, etc. General IDW handling guidelines include:

Use only drums and containers that meet the appropriate U.S. Department of Transportation (DOT)

or UN certification standards. It is our general practices to use UN1A2 55-gallon drums.

Label and identify drums and containers when moved to the staging areas onto the drum caddies.

Segregate incompatible drums and media.

Staging areas shall be provided with adequate ingress and egress routes.

Inspect the integrity of the drum or container before filling and/or moving. Suspect containers will be

removed from service and the contents transferred into acceptable containers.

Never fill a drum greater than 80%. If drum handling equipment is not available place the drums on

the drum caddies and fill using smaller more manageable containers.

The second is the investigation of unknown drums. The following general guidelines shall be followed:

Be aware of the potential hazards of the contents of drums or containers before handling. Only

trained personnel should open drums containing unknown materials.

Bulging drums or containers are an indication of pressure buildup. Open all drums or bungs extremely

slowly to determine the presence of vapors or pressure inside the drum. If the possibility of fire or

explosion exists, a protective shield and/or remote opening devices should be used.

Consider any unlabeled drum or container as containing a hazardous substance and leave it alone

until contents are properly identified and labeled. Do not assume that exterior labeling properly

identifies the contents or potential hazards of drums and containers.

Staging areas shall be provided with adequate ingress and egress routes.

Inspect the integrity of the drum or container before moving. Any drum or container lacking integrity

shall be overpacked.

Organize site operations to minimize the amount of drum or container movement. Have a clear view

of the available pathway when moving drums. If needed, an additional person should be available to

provide guidance.

Utilize drum container handling equipment whenever possible. The equipment utilized should have a

sufficiently rated load capacity, and should be able to operate smoothly on the available surface.



Use proper lifting and moving techniques to prevent back injuries, if handling equipment is not

available.

Never stand on drums or containers.

Use non-sparking tools.

Cease site operations immediately if site activities uncover buried drums or containers. The SSO

must be notified. The SSO will evacuate the area. All unknown situations must be evaluated before

site activities are resumed. The services of a specialized contractor trained in handling unknown

contaminants may be needed. If, after evaluating the situation, only a portion of the site is affected,

that area shall be barricaded and work may continue at other portions of the site.

In these situations, upgraded levels of personal protection will be incorporated into the SSHASP as well

as Section 11.0 from the Tetra Tech HSGM Drum and Container Management Program, if necessary.

Dewatering Areas/Excavation Dewatering

As some of the contaminated soils/sediments will be removed from the Storm Drain system there will be

the necessity for dewatering.

Dewatering Areas

These areas will be surrounded by a berm and silt fence to control water migration. Water will be

collected using sump pumps within sumps constructed at the dewatering area. Water will be pumped to

the frac tanks containing the wash water from the Drain cleaning.

These areas will be demarcated using construction fencing and signs. The sediments and saturated soils

will be covered using visqueen or tarps to prevent resaturation or potentially minimize dispersal.

6.2.10 Inclement Weather

Project tasks under this Scope of Work will be performed outdoors. As a result, inclement weather may

be encountered. In the event that adverse weather (electrical storms, tornadoes, etc.) conditions arise,

the FOL and/or the SSO will be responsible for temporarily suspending or terminating activities until

hazardous conditions no longer exist.

Adverse weather is defined as winds in excess of 35 knots (40.3 mph), heavy rain, hail, or the potential

for lightning within 5 nautical miles that could affect the site within 30 minutes.



When lightning is within five miles of the work site, personnel will terminate work and move into a

protected area. If a supported means for weather predication is not available then site personnel will

utilize the NOAA 30/30 Rule, which is:

If there is less than 30 seconds between lightning and thunder,

go inside or to a protected area and stay inside until 30 minutes after the last thunder.

It is recommended when working in areas plagued by storms during certain times of the year that

lightning warning devices be used. If necessary, the SSO or FOL will regularly check weather status,

particularly if the weather changes.

6.2.11 Heat and Cold Stress

Because of the length of planned project activities, the likely seasonal weather conditions that will exist

during the planned schedule, and the physical exertion that can be anticipated with some of the planned

tasks, it will be necessary for the field team to be aware of the signs and symptoms and the measures

appropriate to prevent cold stress. This is addressed in detail in Section 4.0 of the Tetra Tech HSGM,

which the SSO is responsible for reviewing and implementing as appropriate on this project.

6.2.12 Fire

All personnel will be knowledgeable of fire prevention procedures, firefighting techniques, and essential

precautions to prevent injury. This includes knowledge of the classes of fires and the operation of fire

extinguishers. All personnel shall:

Keep fire extinguishers in a ready condition and accessible at all times. Access to or visibility of

extinguishers shall not be obstructed.

Store only the minimum required supply of paints, solvents, or other flammables from storage. At no

time shall the quantity removed exceed one day’s working supply.

Do not allow combustible products of rubbish, waste or other residues to accumulate, oil-soaked rags

and material subject to spontaneous combustion shall only be stored in non-combustible containers

with self-closing lids.

Do not store gasoline, flammable solvents, and liquids inside a building unless the structure has been

approved for flammable storage containers. Only OSHA-approved storage cabinets shall be used for

all flammable liquids, paints or solvents.

Flammable liquids shall be stored in locations that will not interfere with evacuation of the area in

case of a fire.



Do not permit smoking, striking of matches, or other sources of ignition outside of designated

“SMOKING” areas.

Discard cigarette butts, matches or other similar materials in non-combustible containers.

Do not stop to get anything out of a building or area if evacuation is required. JUST GET OUT - and

assemble in the predetermined evacuation assembly points.

Conduct hot work in accordance with Hot Work Permit and LM/MRC procedures.

6.2.13 Pinch/Compression Points

Handling of tools, machinery, and other equipment on site may expose personnel to pinch/compression

point hazards during normal work activities. Where applicable, equipment will have intact and functional

guarding to prevent personnel contact with hazards. Personnel will exercise caution when working

around pinch/compression points, using additional tools or devices (e.g., pinch bars) to remove hands

and fingers from these pinch/compression points when completing these activities.

Common sense should be applied when working with hand tools. For instance when applying torque of

force on a wrench towards and immovable object.

In all cases, personnel shall evaluate machine and associated structural components during maintenance

and construction for the necessity to employ Lock Out/Tagout for energy isolation purposes.

Remember – Kinetic and potential energy must be addressed.

6.3 NATURAL HAZARDS

Natural hazards such as poisonous plants, bites from poisonous or disease carrying animals or insects

(e.g., snakes, ticks, mosquitoes) are not anticipated at this work site as it is within a relative maintained

area.

As with any medical condition or allergy, information regarding the condition must be listed on the Medical

Data Sheet (see Attachment IV of this SSHASP), and the FOL or SSO notified.



7.0 AIR MONITORING/SAMPLING

This section will discuss air monitoring methods as well as air sampling that may be using during

investigatory or remedial site activities at Block E. Air monitoring/air sampling will be performed to

evaluate airborne concentrations of site contaminants at source points, (excavations, confined space

during Storm Drain repair) worker breathing zones, general work areas, and perimeter boundaries as well

as down wind points to document criteria for worker safety including potential exposures, determine

protective measures for the site personnel, as well as ascertaining emission levels that could have an

impact on the surrounding public. It is necessary for an effective air monitoring/air sampling program to

be tailored to meet the conditions found at Block E.

Information regarding potential contaminant levels at the Block E site have been reviewed to determine

contaminant identification and concentrations as well as physical properties. Based on this information

overexposure could occur to persons working with or handling this media given the source

concentrations. Real time monitoring along with Dust monitoring will be conducted to confirm this

assessment.

Real time monitoring instrument will be employed to monitor airborne particulate levels and particulate

sizes. The results from these instruments will also be used to evaluate exposure potential as well as

assess PPE levels or the necessity to upgrade based on reaching a predetermined action level(s). Based

on the airborne concentration necessary to exceed OELs exposure is highly unlikely.

7.1 PHOTOIONIZATION DETECTOR AND/OR FLAME IONIZATION DETECTOR

A photoionization detector (PID) (or flame ionization detector [FID]) with a lamp energy of 10.6 electron

volts (eV) or higher will be used to evaluate the presence of potential VOCs of concern. This instrument

will be used to monitor potential source points and to screen the breathing zones of employees during site

activities (particularly during intrusive operations such as sampling). The PID has been selected because

it is capable of detecting the organic vapors of concern (A flame ionization detector [FID] may be used as

an alternative to the PID).

Before starting any field activities, the background levels at the site must be determined and noted. Daily

background readings will be taken away from any areas of potential contamination. These readings, any

influencing conditions (weather, temperature, humidity, etc.), and site location must be documented in the

field operations logbook or other site documentation (e.g., sample log sheet).



7.1.1 Frequency of Monitoring

The FID or PID will be used initially to screen potential source areas (sample locations) to determine the

presence of any detectable VOCs. If VOCs are detected, worker breathing zones will be monitored to

evaluate potential exposures. Refer to the SWPs for specific air monitoring procedures.

7.1.2 Instrument Action Levels

The use of either a PID or an FID will be acceptable, provided that the following action levels are

observed:

PID action level: 1.00 ppm above background in breathing zoned areas for 4 exposures of no more

than 3 minutes per day.

FID action level: 2.00 ppm above background in breathing zone areas for 4 exposures of no more

than 3 minutes per day.

7.2 DUST MONITORS

Dust will be monitored during the construction activities, including excavation, pipe cleaning, offloading

sediment and or soils into rolloff containers to avoid dispersion or inhalation of contaminated dusts or

particulates. In addition to visual observation of the working conditions, a field operated mini respirable

aerosol monitor will be used to monitor the airborne dust concentrations during soil and sediment

removal. Dust monitors are used when airborne particulates may be generated as a result of site activities

and pose a potential for exposure via inhalation. These instruments measure real time concentrations of

airborne particulates such as dust, smoke, mists, and fumes within a range of 0.01 to 100 mg/m3. These

instruments also provide gradient measures based on the size of the particulates. In addition, to

monitoring dust concentrations visual observations will be utilized to determine if a corrective measure

needs to be put in place. Airborne dust concentrations become visible at a concentration of approximately

2.5 mg/m3. Therefore, visual assessment will be utilized as a determination when to apply water to control

emissions through area wetting.

Note: Sediment removal from the pipes will be a wet operation the sediments/water are vacuumed from

the pipes and stored in metal containers so dust from the operation is not anticipated. Manhole repairs

are from small areas, a few square feet, the vacuum and hand work will be done so dust generation

beyond the immediate manhole area is not anticipated. Three dust monitors, one upwind and two

downwind, will be placed in the perimeter of the work area to monitor for dust and that the results will be

checked periodically each day and summarized in the final report.



Area Wetting

To control airborne particulates, area wetting will be utilized to knock down particulates generated during

excavation and pipe cleaning. This will be done in response to visual indications of airborne dust and as it

pertains to particulate measurements using the Mini-Ram Dust Monitor. The action levels is <2.5 mg/m3.

If the action level 3.0mg/m3 are reached, area wetting methods will be employed to reduce particle and/or

dust levels. Water will be applied by the means of trucks, hoses, and/or sprinklers at a sufficient

frequency and quantity to limit dust generation. Additional dust control measure to be employed during

the project will include the use of tarps or plastic as temporary covers, limiting work during periods of high

winds, and emptying or loading haul vehicles slowly and covering loads for haulage.

If area wetting techniques are ineffective and if dust levels are greater than 3.0 mg/m3 site workers will

discontinued work until sufficient water maybe applied to control dust generation and the readings or

visual indications subside. Once elevated readings subside site workers may continue at the direction of

the SSO. If sustained readings are observes, contact the PSHO for additional guidance on air monitoring

procedures and levels of protection.

7.3 AIR MONITORING RESULTS

Observed readings within worker breathing zones and compare to established action levels that will

ultimately direct field personnel to implement additional exposure control methods (area wetting, etc.), or

site activity alteration.

The SSO may decide to increase the frequency of air monitoring based on instrument responses and site

observations. The frequency in which monitoring is performed will not be reduced without the prior

consent of the PHSO or HSM.

The results accumulated will be shared with personnel during Tail Gate/Safety meetings as well as

posting these results after they have been validated through pre and post calibration. In situations where

air sampling has been conducted the SSO will discuss the validated results with those sampled and post

these results as a mechanism intended to share these results with field personnel.

Perimeter monitoring points should be identified so the results maybe linked to a location.



7.4 INSTRUMENTS AND USE

Instruments will be used primarily to monitor source points, worker breathing zone areas, fenceline or

boundary perimeter while observing instrument action levels.

The action levels will incorporate the contaminants of concern, concentration, correction factor, and

instruments level of accuracy.

The action levels will be compared to a background reading for the site. The SSO shall obtain and

document the daily background (BG) reading at an upwind, unaffected area and observe for readings

above that BG level.

It should be noted that baseline monitoring and sampling results shall be obtained prior to the start of

excavation activities to ensure pre-existing conditions are not incorporated as activity based results.

The SSO shall monitor source areas (e.g., monitoring wells, excavation boundaries, perimeter boundaries

and down wind locations at 100 and 300 meters) for the presence of any reading above the daily-

established BG level. If elevated readings are observed at the source location, the SSO shall monitor the

workers breathing zone (BZ) areas of affected workers especially those considered high risk (working in

the areas of the highest concentrations. If the appropriate instrument Action Level is exceeded (see

below), the following process will be followed:

The SSO shall order area wetting or increased water application. Work activity will be delayed until

visual indications and monitoring results are below action levels all personnel to stop work and retreat

upwind to a safe, unaffected area, where they will remain until further directed by the SSO.

The SSO shall allow at least 5 minutes to pass so that the work area can ventilate, and will then re-

approach the work area while continuously monitoring the BZ areas.

7.5 INSTRUMENT MAINTENANCE AND CALIBRATION

Hazard monitoring instruments will be maintained and pre-field calibrated by the equipment provider (i.e.,

rental agency used). Operational checks and field calibration will be performed on site instruments each

day prior to their use. Field calibration will be performed on instruments according to manufacturer’s

recommendations. These operational checks and calibration efforts will be performed in a manner that

complies with the employees health and safety training, the manufacturer's recommendations, and with

the applicable manufacturer standard operating procedure (which the SSO must assure are included with

the instrument upon its receipt onsite). Field calibration efforts must be documented. Figure 7-1 is



provided for documenting these calibration efforts. This information may instead be recorded in a field

operations logbook, provided that the information specified in Figure 7-1 is recorded. This required

information includes the following:

Date calibration was performed

Individual calibrating the instrument

Instrument name, model, and serial number

Any relevant instrument settings and resultant readings (before and after) calibration

Identification of the calibration standard (lot no., source concentration, supplier)

Any relevant comments or remarks

7.6 DOCUMENTING INSTRUMENT READINGS

The SSO is responsible for ensuring that air monitoring instruments are used in accordance with the

specifications of this MHASP and with manufacturer’s specifications/recommendations. In addition, the

SSO is also responsible for ensuring that all instrument use is documented. This requirement can be

satisfied either by recording instrument readings on pre-printed sampling log sheets or in a field log book.

This includes the requirement for documenting instrument readings that indicate no elevated readings above noted daily background levels (i.e., no-exposure readings). At a minimum, the SSO

must document the following information for each use of an air monitoring device:

Date, time, and duration of the reading

Site location where the reading was obtained

Instrument used (e.g., PID, FID, etc.)

Personnel present at the area where the reading was noted

Other conditions that are considered relevant to the SSO (such as weather conditions, possible

instrument interferences, etc.)

The Air Sampling instruments will be calibrated in accordance with the manufacturer requirements. See

the air sampling plan for this information.

9.0 SITE CONTROL

This section outlines the means by which Tetra Tech will delineate work zones and use these work zones

in conjunction with decontamination procedures and good work hygiene procedures to prevent the spread

of contaminants into previously unaffected areas of the site. It is anticipated that a three-zone approach

will be used during work at this site. This approach will be comprised of an exclusion zone, a

contamination reduction zone, and a support zone. It is also anticipated that this approach will control

access to site work areas, restricting access by the general public, minimizing the potential for the spread

of contaminants, and protecting individuals who are not cleared to enter work areas.

9.1 EXCLUSION ZONE

The exclusion zone will be considered the areas of the site of Storm Drain pipe inspection or repair. It is

anticipated that the areas around active/intrusive activates will have the potential for contaminants

brought to the surface or where active construction operations are in progress. These areas will be

demarcated using construction fencing and signs to warn personnel to maintain safe distances. Once

active/intrusive activities have been completed, the site restored, the fencing will be removed to allow

open access.

9.1.1 Vehicular and Equipment Traffic

Hazards associated with vehicular and equipment traffic will exist during various site activities and

whenever site personnel performed work on or near roadways. To minimize the potential for injuries

associated with these hazards, a traffic control plan will be prepared by site personnel and submitted for

approval by LMMRC officials. Site personnel will implement the traffic control plan through the use of

warning signs, traffic cones, and flagmen. Additionally, site personnel will be instructed to maintain

awareness of traffic and moving equipment when performing site activities. When working near

roadways, site personnel will wear high visibility vests.

9.1.2 Exclusion Zone Boundary Clearances

Personnel working in the exclusion zone are required to wear the required level of PPE as indicated in

this SSHASP. An entry and exit checkpoint will be identified at the periphery of the exclusion zone to

regulate movement of personnel and equipment into and out of the zone. Some general Exclusion Zone

dimensions are as follows:



Excavation Operations/Storm Drain Repair – The excavation area will be fenced to demarcate the

general boundary. Within this area, personnel on the ground will maintain 25-feet surrounding the

Excavation/Storm Drain Repair operation. Personnel may approach these areas only when the

excavator operator has placed the bucket on the ground has disengaged the controls. During

excavation activities, no ground personnel are permitted within the length of a fully extend boom plus

10-feet. Ground personnel will signal the operator who will place the bucket on the ground and

disengage the controls. At this time ground personnel can approach. Fences will be used to mark the

excavation boundary showing how close personnel will be permitted to approach.

25 feet surrounding trenching operation (installation of pipe or concrete inlet box or catch basin).

10-feet low pressure decontamination activities

Confined Space Entry – 25 feet surrounding the entry point.

Exclusion zones inside the construction fencing may be delineated using signs, barrier tape, cones and/or

drive poles, and other postings to inform and direct facility site personnel and visitors, as necessary.

Physical barriers will be at the PHSO and the SSO determination based on site the tasks to be conducted

and the necessity for complete control due to adjacent operations. In the event that exclusion zone

cannot be adequately marked given the configuration work area, Tetra Tech site personnel will be

responsible for policing the area and keeping unauthorized personnel from areas where potential

exposure concerns may exist. Signs will also be used to alert other site personnel or visitors of the

hazardous nature of the work being performed. Signs will instruct personnel to stay out of the area.

Note: Clearances as specified above may not be possible when working in close proximity to roads.

Field crews will take all precautions to assure that the work site is secured when it is not possible to

maintain the 25 foot clearance.

Subsurface activities will proceed only when utility clearance has been obtained. In the event that a utility

is struck during a subsurface investigative activity, the emergency numbers provided in Section 2.0,

Table 2-1, will be notified.

9.2 CONTAMINATION REDUCTION ZONE

The contamination reduction zone (CRZ) in some instances will be a buffer area between the exclusion

zone and any area of the site where contamination is not suspected. This area will also serve as a focal

point in supporting exclusion zone activities. Strict adherence to access/egress and decontamination

within this area must be adhered to, to prevent the potential migration of contamination.



Decontamination will be conducted at a central location. Portable equipment potentially contaminated will

be bagged and taken to that location for decontamination.

In some instances the CRZ will be separated from the exclusion zone such as having an isolated truck

wash or when the drill rig and components are transported to a centralized decontamination area. The

FOL and/or the SSO will determine which scenario best supports site activities.

9.3 SUPPORT ZONE

The support zone for this project will include a staging area where site vehicles will be parked, equipment

will be unloaded, and where food and drink containers will be maintained. The support zones will be

established at areas of the site where away from potential exposure to site contaminants during normal

working conditions or foreseeable emergencies.

9.3.1 Sanitation and Break Areas

This section will address the following items:

Toilets

Potable water

Showers and change rooms

Break Areas

9.3.1.1 Toilets

One toilet will be provided for every 20 people. All toilets will be unisex and will have locking doors. The

toilet provided will either be a chemical toilet and service provider or the flush toilet readily accessible at a

predetermined approved location.

9.3.1.2 Potable Water

Potable water as well as electrolyte balance sports drinks such as Gatorade will be provided to the field

crews for fluid replacement, as it is necessary under conditions of ambient temperature extremes.

Storage and dispensing will proceed as follows:

All containers will be clean and replenished daily.



All containers will clearly marked as to their contents (Potable Water – Drinking Water Only;

Gatorade, etc.).

Dispensing locations will be placed in identified break areas within the support zone. The most likely

location will be at a support vehicle staged near the work area. This will serve as an area for cooling

or warming as well as an identified food and drink consumption area.

If larger containers are used, dispensing cups will be provided.

The coolers used for storage of potable drinks and cups will be stored in plastic bags away from

potentially contaminating materials when not in use.

As it is undetermined when this field activity will be conducted, Fluid intake recommendations will not be

made but determined as necessary based on ambient conditions. Control measures concerning heat and

cold stress provide fluid intake recommendations in those section of the 4.0HSGM should it be necessary

in controlling heat stress and/or hypothermia.

9.3.1.3 Showers and Change Rooms

Based on this scope and duration of this project shower facilities and locker rooms will not be required.

9.3.1.4 Break Areas

Given the location and the time of the year structured suitable locations for work breaks and

warming/cooling regimens will utilize the site vehicles for warming and to remove themselves from severe

ambient conditions.

9.3.2 Administration Area

The Tetra Tech SSO will ensure that a Safety and Health Bulletin Board or notebook is maintained on site

in an area that is commonly accessed by site workers. This bulletin board or notebook will be maintained

with current information, in clear view of onsite workers, and will be protected against the elements and

against unauthorized removal. At a minimum, the following information shall be maintained on the

bulletin board:

Map depicting the route to the nearest medical care facility (This will also be provide for all site

vehicles).



Site map depicting access routes/entry and exit points; possible dispersion routes; utilities; sediment

and erosion control, etc.

Emergency phone numbers (This will also be provide for all site vehicles).

Current copy of the OSHA Form 300A (as applicable) (February to March)

Copy of a Safety and Health deficiency tracking log (optional)

Safety and Health promotional posters (optional)

Date of last workday injury (optional)

OSHA Safety and Health Poster .

Tetra Tech, Inc. Health and Safety Policy.

DRIs results

9.3.3 Marking of Temporary Structures and Trailers.

All structures and/or trailers used on site will be marked as follows:

Contractor’s Name (Tetra Tech, Inc.)

Emergency Telephone Numbers and points of contact.

All trailers as well as any equipment and/or supplies that could become airborne will be tied down or

otherwise secured.

9.4 SAFE WORK PERMITS

Exclusion Zone work conducted in support of this project will be performed using Safe Work Permits

(SWPs) to guide and direct field crews on a task by task basis. An example of the SWP to be used is

provided in Figure 9-1. Partially completed SWPs for the work to be performed are attached

(Attachment V) to this SSHASP. It is the SSO's responsibility to finalize and complete all blank portions

of the SWPs based on current, existing conditions the day the task is to be performed, and then review

that completed permit with all task participants as part of a pre-task tail gate briefing session. This will

ensure that site-specific considerations and changing conditions are appropriately incorporated into the

SWP, provide the SSO with a structured format for conducting the tail gate sessions, as well will also give

personnel an opportunity to ask questions and make suggestions. All SWPs require the signature of the

FOL or SSO.

Safe work permits should be re-issued when moving to other site locations where control measures and

hazards may change.



9.5 SITE SECURITY

As this activity will take place at an active facility, the first line of security will be provided by the facility

entrance/gate restricting the general public. The second line of security will take place at the work site

referring interested parties to the FOL and LMC Contact.

Security at the work areas will be accomplished using field personnel. This is a multiple person

operation, involving multiple operational zones. Tetra Tech personnel will retain complete control over

active operational zones.

The site contact will serve as the focal point for facility personnel and interested parties and will serve as

the primary enforcement contact.

9.6 SITE MAP

Once the areas of contamination, access routes, topography, and dispersion routes are determined, a

site map will be generated and adjusted as site conditions change. These maps will be posted to

illustrate up-to-date collection of contaminants and adjustment of zones and access points.

9.7 BUDDY SYSTEM

Personnel engaged in on site activities will practice the "buddy system" to ensure the safety of personnel

involved in this operation.

9.8 COMMUNICATION

As personnel will be working in proximity to one another during field activities, a supported means of

communication between field crew members will not be necessary.

External communication will be accomplished by using the cell phones/telephones at predetermined and

approved locations. External communication will primarily be used for the purpose of resource and

emergency resource communications. Prior to the commencement of activities at the LM/MRC, the FOL

will determine and arrange for telephone communications.

9.9 SELF-AUDITS

The procedures outlined in Section 7 of the LM Handbook (Attachment I) addressing self-audits will be

adhered to.



Tetra Tech and/or subcontractor personnel will perform periodic work area/project field inspections to

monitor compliance with project environmental, safety and health requirements. The name of Tetra

Tech’s jobsite health and safety (H&S) representative will be provided to LM/MRC POC prior to starting

work at the jobsite.

For jobs that are ongoing, an annual H&S audit shall be conducted and for jobs with a duration of less

than one year at least one audit shall occur. A competent H&S representative designated by the Tetra

Tech shall perform the audit. Unsafe acts and/or non-compliance conditions noted during inspections

shall be corrected immediately.

The documentation related to the audits and inspections shall be submitted electronically to the LM/MRC

Project Lead.

10.0 SPILL CONTAINMENT PROGRAM AND WASTE MANAGEMENT PLAN

10.1 SCOPE AND APPLICATION

Bulk hazardous materials (over 55-gallons) may be generated or handled at any given time as part of this

scope of work. Therefore, this Spill Containment Program was generated to support responding to such

spillage would constitute a danger to human health or the environment.

10.2 POTENTIAL SPILL AREAS

Potential spill areas will be periodically monitored in an ongoing attempt to prevent and control further

potential contamination of the environment. Currently, limited areas are vulnerable to this hazard

including:

Exclusion zones/Resource deployment

Pipeline, or Drain box/catch basin repair or replacement

Central staging or locations where rolloffs and Frac Tanks are located or deployed

10.2.1 Exclusion Zone/Resource Deployment

The potential exists for contaminated soil to be excavated during the pipeline and Drain box repair

operation creating the possibility of a spill of soils, water or sediment. To combat this, the following

mechanisms will be used:

Frequent excavation inspections (preventative)

Frequent air monitoring to reveal elevated readings prior to reaching the action levels

10.2.2 Waste Transfer/Loading

To minimize spills and the spread of contamination when removing or containerizing soils, sediments or

liquids the following measures will be taken:

Incidental loose materials will be removed from the sides of rolloff bodies using brooms or other

devices to prevent the spread of contaminated materials. Operators will exercise care to prevent

spilling during loading.

All rolloffs will be equipped with tarps and be water tight to control the material during transport.



A centralized decontamination station will be established to prevent spread of contamination.

Berms, silt fences will be constructed and maintained to ensure surface migration of contaminated

soils or water does not occur.

Trucks may be decontaminated prior to leaving the site if comntamination is found during inspection

prior to entering public thoroughfares.

All gates will be sealable or liners will be employed to insure no leakage can or will occur.

A load inspection will be conducted prior to signing the manifest and releasing the truck from the site.

Trucks failing to meet equipment or operational requirements will not be used.

10.2.3 Central Staging

In order to facilitate leak and spill inspection and response, and to minimize potential hazards which may

impact the integrity of the storage containers, the staging area for these substances will be structured as

follows.

10.2.4 IDW

Water tight Rolloffs will be used for soils and sediments removed from pipe and the excavations.

Rolloffs will covered once filling is completed prior to transportation.

Drums used for incidental storage - 55 Gallon Drums (United Nations 1A2 configurations) – 4 Drums

to a Spill Pallet; labels and the retaining ring bolt and nut on the outside of each drum to facilitate

easy access; Minimum 4 feet between each row of pallets.

Storage Tank – Polyethylene Construction – Frac Tanks shall be placed in a bermed enclosure of

sufficient size to accommodate these containers can be used for water storage and decontamination

waters if needed.

Regardless of container types selected, the staging area will be identified as a Satellite Storage Area with

proper signage, points of contact in the event of an emergency, alternate contacts, and identification of

stored material (i.e., decontamination waters, soils or sediments , etc.).

An Inventory Log will be maintained by the FOL or the SSO regarding types of IDW and volumes

generated. An updated Inventory List will be provided by to the designated LM/MRC POC during days off

and between shifts or phases of operations as directed by the PM.



10.2.5 Flammable/POL Storage

Flammable Storage [i.e., fuels, decontamination solvents (Isopropanol)] and Petroleum/oil/lubricants

(POL) will require proper dispensing containers. Storage and dispensing will comply with the following

requirements:

Fuels, which will be stored and dispensed from portable containers, will utilize safety cans.

Portable hand held storage containers will be labeled per OSHA Hazard Communication standard

requirements.

Larger volumes stored for fueling equipment will be stored in approved mobile Above Ground Storage

Tanks with secondary containment capable of holding the tank volume plus 10%.

Portable flammable liquid storage tanks will be properly grounded and will have bonding capabilities

through the hose or via a separate connection for the transfer of loading and off-loading of its

contents.

Dispensing locations will be supported by a fire extinguisher positioned no closer than 50 feet from

the storage tank, properly mounted and identified.

The storage location will be well marked with proper signage, protective bumper poles and will have

straight through access/egress for vehicles.

These areas will be supported by fire extinguishment services and spill response materials.

Selection and placement of the area will be away from transportation pathways and bodies of water.

10.3 LEAK AND SPILL DETECTION

To establish an early detection of potential spills or leaks, a periodic walk-around by site personnel during

working hours to visually determine that storage vessels are not leaking. If a leak is detected, the

contents will be transferred or patched to control the release.

POLs – All petroleum leaks will be collected and contained using absorbents such as Oil-Dry, or sand,

and will be placed in a conspicuously marked drum. This used material, too, will be containerized for

disposal pending analysis. Inspections will be documented in the project logbook.

Decontamination/Dewatering Fluids – All waters (if contaminated) released to the environment will

require the affected area to be scraped removing affected soils. These materials will be added and mixed

in with the contaminated soils for disposal.

In case of a spill or release of hazardous chemicals, Tetra Tech shall immediately notify the LM Project

Lead, and/or if the severity of the spill warrants, the local fire department by calling 9-1-1. Tetra Tech



shall take all necessary steps to control the spread of the release and to provide site control to prevent

unauthorized personnel from entering the affected area.

Section 8.2 of the LM Handbook (Attachment I) pertaining to spill reporting will be addresses.

10.4 PERSONNEL TRAINING AND SPILL PREVENTION

Personnel will be instructed in the procedures for incipient spill prevention, containment, and collection of

hazardous materials in the site-specific training. The FOL and the SSO will serve as the Spill Response

Coordinators for this operation, should the need arise.

10.5 SPILL PREVENTION AND CONTAINMENT EQUIPMENT

The following represents the types of equipment that should be maintained at the staging areas for the

purpose of supporting this Spill Prevention/Containment Program.

Sand, clean fill, or other non combustible absorbent (Oil-dry)

Drums (55-gallon U.S. DOT 1A1 or 1A2)

Shovels, rakes, and brooms

Container labels

Hazardous materials shall be stored in designated areas and all containers effectively closed. Spill

equipment/supplied shall be readily available to contain and/or mitigate accidental spills of hazardous

materials.

10.6 SPILL CONTROL PLAN

This section describes the procedures the Tetra Tech field crew members will employ upon the detection

of a spill or leak.

Employ incidental response measures to control the spill as soon as possible.

Notify the SSO or FOL immediately upon detection of a leak or spill. Activate emergency alerting

procedures for that area to remove non-essential personnel IF the spill containment measures are

determined to be greater than the capabilities of the field staff and resources.

Employ the personal protective equipment stored at the staging area. Take immediate actions to stop

the leak or spill by plugging or patching the container or raising the leak to the highest point in the

vessel. Spread the absorbent material in the area of the spill, covering it completely.



Transfer the material to a new vessel where possible; collect and containerize the absorbent material.

Label the new container appropriately. Await analyses for treatment and disposal options. POLs and

Remedial and Investigative derived wastes will be handled separately.

If a spill happens the following information will be collected:

Identity of the material spilled;

The amount spilled;

Where it was spilled;

If it is currently controlled;

If it has reached any bodies of water (i.e., storm water, bodies of water, etc.)

It is not anticipated that a spill will occur that the field crew cannot handle. Should this occur, notification

of the appropriate Emergency Response agencies will be carried out by the FOL or SSO in accordance

with the procedures discussed in Section 2.0 of the MHASP.

As mentioned above, in the event of a spill or release of hazardous chemicals, Tetra Tech will

immediately notify the LMC personnel in the order presented in Table 2-1, and/or if the severity of the spill

warrants, the local fire department by calling 9-1-1.

WASTE MANAGEMENT PLAN

Tetra Tech personnel will adhere to the decontamination and waste management procedures laid out in

the Waste Management Plan and Addendum #1, the Tetra Tech HSGM (Sections 11.0 and 12.0), the

Tetra Tech Decontamination of Field Equipment and Waste Handling Standard Operating Procedure

(Attachment XII).

In addition, all requirements described in Sections 4.1 and 4.2 of the LM Handbook (Attachment I) will be

addressed.



11.0 CONFINED-SPACE ENTRY

It is anticipated under the proposed scope of work that a confined space entry will be conducted in the

Block E Storm Drain System.

The TtNUS Confined Space Entry Operations Program is included as Attachment III. A Safe Work Permit

for this task is also included in Attachment III. Field personnel specifically trained under the guidelines of

OSHA 29 CFR 1910.146 will be assigned to this project.

Entries into the Block E Storm Drain System will be conducted consistent with the requirements of the

Tetra Tech Confined Space Entry Operations Program. Based on previous data, there is evidence to

suggest that chemical and/or physical hazards are present within the space. Air monitoring will be

performed to document the atmosphere in the space and determine precautions and protective

equipment to use when entering the confined space. Should other than background concentrations of

agents (toxics and/or oxygen deficiency) be detected, operations shall cease and the PHSO and the HSM

shall be notified.



12.0 HOT WORK

While no hot work activities are planned based on the scope of work, inevitably the necessity to conduct

hot work will be required.

Within the construction remediation component there are greater opportunities for performing hot work.

At LM/MRC Hot Work Permit requests are directed through the Fire Department. It is ask that when

requesting a Hot Work Permit allow for 2-days. While it seldom takes this long it is requested that this

amount of time be scheduled into the planning component.

A Hot work permit will be required when you are employing:

Open flames (oxy/acetylene; tar buggies, etc.) or

Heat producing devices or

Welding cutting operations

Flammable Materials storage

In support of Fire prevention the following measures will be required when requesting a Hot Work Permit:

Are fire prevention control measures in place?

Have combustibles been removed from the area (at least 35-feet from the ignition source)where the

work will be conducted?

Has a Fire Watch been assigned to the activity? Will the fire watch remain after the termination of the

activity for at least 30 minutes?

Have the correct extinguishing media been placed in the area of the hot work?

Are all persons assigned to this tasked trained in Fire Extinguisher use?

Have adequate shielding been installed to protect adjacent workers and drivers on adjacent

roadways?

In order to answer these questions in each application Tetra Tech employs a Hot Work Permit. See

Figure 12-1, Hot Work Permit.

See also Section 3.4 of the LM Handbook for additional information. (Attachment I).

TETRA TECH NUS

CONFINED SPACE ENTRY OPERATIONS PROGRAM 1.0 PURPOSE

To establish a uniform procedure specifying the minimum requirements for confined space entry

operations performed by (or managed by) Tetra Tech NUS, Inc.

2.0 SCOPE

For the purpose of cla rification, thi s p rogram a pplies to confined sp ace op erations which falls

within the definitions provided below for confined spaces and permit required confined spaces.

Confined space. A confined space means a space that:

Is large enough and so configured to permit an employee to enter and perform work; and,

Has limited or re stricted means for e ntry or exit (for example, tanks, vessels, silo s,

storage bins, hoppers, vaults, pits, etc.); and,

Is not designed for continuous employee occupancy.

Permit required confined space (PRCS). A confined space having one or more of the following

characteristics:

Contains a h azardous at mosphere, o r po ssesses t he p otential t o contain a hazardous

atmosphere.

Contains a material which has the potential for engulfing an entrant.

Has an i nternal configu ration su ch tha t an entrant entering t he PRCS coul d become

entrapped or asphyxiated by inwardly converging walls or a floor which slopes downward,

tapering to a smaller cross-section.

Contains any other recognized serious safety or health hazard, or by virtue of the task to

be undertaken, may generate unsafe conditions.

A-V-2

This procedure ap plies to a ll pr ojects with a scope of wo rk that inclu des the perfo rmance of

confined space entry operations by Tetra Te ch NUS or subcontracted personnel. T his program

has been developed on the basis of two principle requirements. These are as follows:

That this program will be i mplemented on a SITE SPECIFIC basis, establishing

flexibility to provide for the protection of the health and safety of Tetra Tech NUS

and subcontractor personnel, as well a s for intern al and re gulatory compliance.

This concept recognizes that Tetra Tech NUS personnel work on many different

sites, often with only b rief field ope rations ta sks, as o pposed to longe r te rm

project sites. Therefore, this performance-based program has been developed to

establish the minimum requirements for co nfined space entry operations at any

individual Tetra Tech NUS office location or project site.

That all confi ned spa ce e ntry operations will be p erformed using a PERMIT-REQUIRED system, with the requi rements of thi s procedu re followed a s

minimum re quirements. Re cognizing t he Fede ral OSHA reg ulatory delineati on

between a Non-permit Confined Space and a Permit-Required Confined Space1,

and al so re cognizing th at OSHA standards are minimum req uirements. It is

Tetra Tech NUS policy that all confined space entry operations will be performed

in accordance with the written permit system specified in this procedure.

3.0 RESPONSIBILITIES

Tetra Tech NUS President: Has the overall respon sibility for the health a nd safety of all

personnel and operations in Tetra Tech NUS, including those involved with confined space entry

operations. This responsibility is prin cipally satisfied through delegating the necessary authority

and accountability to the Tetra Tech NUS Office Management level. Successful accomplishment

and maintenance of this and other h ealth an d safety prog rams will b e a chieved throug h such

means a s ensuring that health an d safety i s a prin cipal component of personnel annual

overall company requirements.

Office Health and Safety Points of Contact (POCs): Ensure that the requi rements of thi s

program are sati sfied fo r all confine d sp ace ent ry ope rations performed or mana ged at their

location, wh ether by T etra Tech NUS personnel or by su bcontractors. Oth er re sponsibilities

include ensuring that:

If training is provided by subcontractors, that an appropriate organization is selected, and

that the training course material satisfies the Tetra Tech NUS requirements.

A-V-4

No i ndividual parti cipates in any confined space ent ry ope rations unle ss they are fully

compliant with all program requirements.

The HSM i s alerted when activities at a project site will involve confined space entry

operations.

A prop erly completed written pro gram is pr esent at every site where co nfined spaces

exist.

Appropriate documentation is mai ntained for that o ffice, and th at written p ermits a re

submitted to the HSM at the conclusion of project activities to facilitate the annual permit

review requirement.

Note: In situations where an Office Health and Safety Point of Contact is filled by an

administrative person not qualified in issues regarding confined space operations, the Tetra Tech

NUS HSM will be responsible for those items listed above.

Site Safety Officers (SSO): Ensure that the requi rements of this program are satisfied for all

confined space entry operations performed or managed at thei r site lo cation, whether by T etra

Tech NUS personnel or by subcontractors. Other responsibilities include ensuring that:

All confined spaces are identified and labeled as such.

All personnel to pa rticipate in confined space are trained to the appropriate level for th e

tasks to be performed and do cumentation certifying this trai ning is obtained an d

maintained on site. In addition, ensure a ll drilling/practice requirements to establish

proficiency are up to date.

All personnel meet the necessary medical qualifications for this type of activity.

Rescue services are e stablished and c onfirmed on the d ates the confined spa ce

operations will be conducted.

Provide the intended rescue services, the necessary information concerning the hazards

associated with the confi ned space o perations. This in cludes Material S afety Data

Sheets, where available, information concerning hazard atmospheres and any associated

physical hazards.

The duties of the Entry Supervisor is completed in their entirety. In many cases the SSO

will serve as the Entry Supervisor.

A-V-5

The site-specific program for confined space operations is completed at each site, where

applicable.

Project Health and Safety Officer (PHSO) - The PHSO shall ensure that confined space activitie s

are adequate ly addressed in the Site Specific Heal th and Sa fety Plan for assigned projects . In

addition, it is the PHSO’s respons ibility to provide technical assistance to the SSO and/or the Field

Operations Leader.

Field Operations Leader (FOL) – The FOL may share responsibility with the SSO or in the absence

of an SSO e nsure the implementa tion of th is program for all ope rations conducted under th eir

direction. Substitution for the SSO will depend on the nature of the confined space operations and

the anticipated severity of the hazards conveyed in the confined space. Substitu tion shall proceed

based on the PHSO recommendation.

Project Manager (PM)/Task Order Manager(TOM) - The PM/TOM is also ultima tely responsible for

the effecti ve compliance with these requirement s. The PM/TOM will ensure that suffi cient

information h as been pro vided to the PHSO to develop a site- specific Confined Space Entr y

Program appropriate for the nature of the planned activities. This is to be accomplished in

conjunction with the preparation of the site-specific Health and Safety Plan (HASP). In addition, the

PM/TOM will ensure all avenues to accomplish a specific task in a manner where confined space

entry o perations a re not ne cessary (such as the use of re mote samplin g tech niques) are

exhausted, and that confi ned space entry is sele cted as a field activity approach only as a last

resort.

Tetra Tech NUS Emplo yees - The employees are responsible for fo llowing the te nets o f this

Confined Space Entry Program and/or conditions or modifications of this program, that may be site-

specific in na ture. In additi on the e mployees are re sponsible for reporting an y de ficiencies or

inadequacies of these program or site-specific elements to the SSO and/or the FOL.

4.0 PROCEDURES

4.1 Introduction

Tetra Tech NUS recognizes that the participation of Tetra Tech NUS personnel in confined space

entry operations can be one of t he most potentially dangerous types of field a ctivities that t hey

may encounter in their wo rk. The risks associated with this type of wo rk are most remarkable

A-V-6

because they can be immediate and severe. It i s for this reason that the requirements o f this

program will be strictly enforced at all Tetra Tech NUS locations.

There a re t wo sce narios that are commonly en countered in Tetra T ech NUS ope rations and

projects. Th ese in clude proje ct site s whe re we are the contractor perfo rming work at a clien t

location, and proj ect sites whe re we a re the prime cont ractor, and we have a sub contractor

working under our direction. Also, spe cific to a ddressing confined space concerns, we need to

address sites where confined spaces exist but our work scope will not involve entry versus sites

where a ctual entry is necessary. A s the regul atory req uirements for each of these scen arios

vary, sepa rate pro cedures are e stablished in the following sect ions of this overall p rogram.

These procedures all inv olve the use of a simple, fill-in-the-bl ank written program that is to be

completed

4.2 General Requirements

The following are General Requirements for each Tetra Tech NUS’s Confined Space Entry policy

and program.

Confined space entry operations on any Tetra Tech NUS project site will be performed only a last

resort. All a vailable alte rnative mea ns to accomplish th e ta sk objectives m ust b e exh austed

before commencing any confined space entry activities.

The following represents scenarios where Tetra Tech NUS, Inc. personnel and/or subcontractor

personnel worki ng u nder the dire ction of Tetra Te ch NUS, Inc. would require the use of this

program.

Tetra Tech NUS, Inc. personnel will enter a confined space.

There are confined spa ces in the are a of operation under the g uidance/control of

Tetra Tech NUS, Inc.

Subcontractor personnel will enter a confined space under th e guidance and/or

direction of Tetra Tech NUS, Inc.

Therefore, any project site where planned activities may involve work in or near a confined space

must have a written Confined Space Entry Program completed on site and available p rior to the

commencement of site activities. The prog ram must be attach ed to the Health and Safety Plan

A-V-7

prepared for that project. The written p rogram shall be completed by the assigned SSO, and will

be kept current and available for review by the Tetra Tech NUS HSM.

All work involving entry into a confined space will be performed by written permit only.

There will be no exceptions to this requirement without the express, written consent of the T etra

Tech NUS HSM.

Role and Responsibility of the Site Safety Officer

For applicable projects, the assi gned SSO must be thoroughly familiar with thi s procedure and

with the OS HA reg ulation on Permit -Required Co nfined Spa ces, and will b e re sponsible for

completing t he on-site elements of this progra m. The SSO will al so be responsi ble for

implementing the specific requirements of the program on his/her site, including ensuring that:

All confined spaces at the site are p roperly identified, labeled, a nd inventoried. Signs

should be a ppropriate si ze (1 2x18 mini mum or greater) an d colo r desi gnation

http://www.osha-slc.gov/OshStd_data/1910_0144.html

All site perso nnel a re ma de aware of these spaces, and that unautho rized entry is

prohibited. This is to be covered as part of the site-specific health and safety training.

All entries a re performed using the written permit system specified in the site written

program.

All necessa ry training requirements are satisfied, and th at app ropriate trainin g

documents are collected and maintained.

All personnel participating in the confined space operation are medically (physically and

psychologically) qualified t o do so. Docu mentation to be provid ed are the medica l

surveillance clearance and the ability to wear respiratory protection.

All necessary entry equipment is on hand, and maintained in proper working order. All

equipment will be inspected by the SSO to ensure operation status.

Permits are completed specifying a duration only long enough to perform the job.

A-V-8

A trained an d equipp ed rescue team is on sta ndby prior to the beginni ng of the

confined space activity. It will be the SSO responsibility to ensure the rescue teams

capabilities and equipment resources to support the planned operation.

The rescue team is fully aware of the potential hazards which may be encountered and

all pertinent information has been provided by the SSO.

The SSO will , in the majority of cases, serve as the Entry Supervisor. This means that he/she is

responsible for determining that acceptable entry conditions are present before and during entry,

for autho rizing (by completing and signing the written permits) an d overseeing entries, and for

terminating entries and canceling permits.

Testing and Monitoring of Confined Spaces

Air monitoring in th e confined space must be performed before and periodically during all entry

operations. The frequency, types, and sequence of air monitoring are clearly specified in the site

specific p rogram in cluded as Appen dix 1. Wh ile that progra m spe cifies that periodi c air

monitoring d uring an entry may be a cceptable fo r an isolated space, it is re commended that

continuos mo nitoring al ways be pe rformed, even fo r a completely isolate d space. Accept able

entry conditions are as specified in Table 1, below.

A-V-9

*LEL = Lower Explosive Limit, sometim es also referred to as LFL for Lower Fl ammability Limit.

For dusts, this may b e approximated as a vis ual condition where the du st obscures vision at a

distance of 5 feet or less.

If the accept able entry condition s do not exis t, or appe ar tha t they may not be co nstant

throughout the entry, the SSO can use the following approach:

1. Ensure th at the spa ce i s prope rly iso lated (block and blee d lines, use Lockout/Tagout

procedures, etc.

2. Purge, inert, flush, or ventilate the space to control or eliminate the hazard.

If acceptable entry conditions still do not exist due to flammability or explosive concerns, the entry

must not be authorized. If the limiting fac tor is toxic airborne concerns, appropriate PPE may be

used to allow the entry (Note: As with all environmental work, use of PPE is chosen as a control

option al ways only a s a last resort. All efforts sh ould b e mad e to co ntrol hazards th rough

engineering controls, where possible).

A-V-10

Rescue

When co nfined sp ace entry oper ations are perfo rmed, pe rsonnel and e quipment mu st be

adequate and available to effect non-entry rescue operations in the event of an emergency. This

shall in clude items su ch as bo dy harne sses (o r wri stlets, a s a second choi ce), tie-offs,

mechanical retrieval apparatus, etc. This equipment must be available and in use during all entry

operations. This will e nable the At tendant an d other auth orized pe rsonnel to perfo rm an

emergency rescue and extract an injured person from outside of the space. Rescue procedures requiring other personnel to enter a space to assist or evacuate an injured or incapacitated entrant are expressly prohibited. Also, u nauthorized pe rsonnel mu st be

prohibited from participating in emergency rescue operations.

It is anticipat ed that in m ost instances, we will be prepared to provide non-entry emergency

rescue services ourselves, at least to the point of removing an injured person and stabilizing them

until professional emergency services can be summoned. The identity of the specific emergency

response service and th e method for contacting them will be clearly ide ntified on the pe rmit

completed by the SSO. At least one member of t he team serv ing in the role of Attend ant o r

Rescue member (a no n-entrant) mu st have cu rrent certification in First Aid a nd CPR. (Note:

The person of choice must ensure that Bloodborne Pathogen Program requirements are satisfied

whenever First Aid or CPR practice is authorized.)

4.3 Employee Training

All personn el must be a dequately trai ned in o rder to be autho rized to pa rticipate in confined

space op erations. Traini ng must be p erformance-based so that particip ants can succe ssfully

demonstrate proficiency in performing their assigned duties. Training shall take place before an

individuals first a ssignment, when th eir assigned duties change, or when changes occur in the

site’s written prog ram. Also, if a ne w ha zard is suspe cted t hat wa s not addresse d in the

employee’s training, supplemental training will b e required. Retraining m ay a lso be conducted

when through periodic inspections or reviews identify deficiencies in confined space operations.

Whether training is provided in-house or by a training contractor, the contents of the training must

satisfy the requireme nts of this program, and will be held to the crite ria published by the

Hazardous Waste Actio n Coalition Ri sk Management Co mmittee, He alth and S afety

Subcommittee (entitled “Confined Space Entry Training Courses”, published in 1996). A co py of

these criteria are available from the Tetra Tech NUS HSM. These criteria are directly applicable

A-V-11

as they have been specifically developed by health and safety representatives of firms from within

our industry (hazardous waste/environmental consulting).

The SSO will ensure that appropriate training has taken place for all a uthorized individuals, and

will have on-hand at the site documentation for each involved employee attesting to:

1. Employee name

2. Signature or initials of the instructor

3. Dates of training

Site-specific training for authorized individuals will cover the duties of the entrants and attendants.

This will address the aspects for each of these positions as presented below.

Authorized Entrants

Hazards that may be encountered in the space

How to properly use the necessary equipment

Communication methods with the Attendant

Recognizing when emergency exit of the space is necessary

Attendants


Behavioral effects of hazard exposure

To continuously maintain an accurate count of entrants and know their identity

To never leave the space unless relieved by another attendant

Communication methods and aspects with Entrants

Monitoring of the space

How and when to summon emergency services

Control unauthorized personnel issues

Performance of non-entry rescues

Entry Supervisor (the SSO)*


Verifies that all tests have been conducted (by checking permit entries)

A-V-12

Verifies that all procedures and equipment specified in the permit are in place before signing

it and putting it into effect

When and how to terminate the entry and cancel the permit

Verify that re scue services a re available at the tim e of the entry and that th e mea ns fo r

summoning them are operable

Removes or prevents unauthorized personnel from entering the space

Offsite emergency rescue services will be contacted by the SS O as part of task mobili zation.

They will be made a ware of the pot ential hazards that may be e ncountered i n p roviding

assistance, a nd (whe n ap propriate), they will be p rovided with Material Safe ty Data Shee ts or

similar information for substances that they may be exposed to.

4.4 Coordination with Clients

In nearly all instances, T etra Tech NUS operations will involve arrangements where we are

serving as a contractor to a client facility. That is, we will not b e addressing entering spaces that

we own or control. T herefore, appropriate coordi nation with the client representative will be

essential to p roperly understand the nature of a ny confined spaces and to su ccessfully perform

the work. When the scope of work entails (or may entail) working in or near confined spaces, the

PM/TOM must gather the following information as part of the initial data gathering process:

1. Obtain any available information regarding confined spaces, including descriptions, potential

or known hazards, and the client’s confined space entry program information.

2. Determine, if the client has located and designated confined spaces in the work area.

3. Establish how the client desires to co ordinate our work with their operations, relative to th e

confined spaces.

4. If the scope of work will i nvolve actual entry by T etra Tech NUS personnel, inform the cli ent

of our program.

Gathered information is to be provide d to the PH SO responsible for pre paring the site -specific

Health and Safety Plan.

At the concl usion of a ny confined space entry work done at a client location, the PM/TOM is to

request a debriefing meeting, so that a representative from the project team can communicate

hazards that were encountered in the work.

A-V-13

4.5 Project Sites Involving Confined Spaces Where Entries Will Not Be Performed

In many instances, we may be performing wo rk at sites where confin ed sp aces exist an d ou r

scope of work does not involve any entry into those spaces. In this application, the SSO has only

to ensure that spaces in our work area are adequately identified and po sted, and com plete the

one-page written program in Appendix 2 and post it on site in the work area.

4.6 Confined Space Entry Operations Involving Subcontractors

For some projects, the scope of work may require a specialized of a su bcontractor. Whe n the

work involve s req uiring a sub contractor to per form a confine d spa ce e ntry, the SSO must

complete and utilize the written program includ ed as Appendix 3. We must provide our

subcontractor with the following information:

1. Information regarding the confin ed space(s), in cluding d escriptions, p otential or known

hazards, and the details of our confined space entry program.

2. Information on the locatio n and de signations (postings) of the co nfined spaces in the work

area.

3. Establish how we desire to coordinate our work with their operations, relative to the co nfined

spaces.

4. If the scope of work will involve actual entry by subcontractor personnel, inquire if they have

their own Permit-Required Confined Space Program and obtain it for our review.

5. If the natu re of the work is such that Tetra Tech NUS and subcontractor personnel will have

to perform concurrent operations in or near a confined space, very close coordination will be

necessary and the Tetra Tech NUS HSM must be contacted for guidance.

At the conclusion of any confined space entry work done by a subcontractor, a debriefing meeting

will be held by the SSO to learn of any hazards that were encountered in the work.

4.7 Program Evaluations And Availability

The Tetra Tech NUS HSM is responsible for performing evaluations of this overall Program to

ensure its continued effectiveness. These reviews will be properly documented, and will occur as

follows:

1. Annually, at the end of each calendar year.

A-V-14

2. At any time when an indication is discovered that a component of the program is not

effective.

3. In the event of any modifications in the regulatory requirements for confined space

operations.

4. If the event of changes or mandates from Tetra Tech, Inc. Corporate Health and Safety.

Annual Program evaluations will entail a review of all canceled written permits prepared and used

during the course of that year by all Tetra Tech NUS locations. The various site-specific written

programs that these permits were prepared under are also subject to review. Canceled permits

will be retained by the Tetra Tech NUS HSM for no less than one calendar year.

Field audits of project work sites where confined space operations are conducted will also be

performed. These will be coordinated through the Tetra Tech NUS HSM , and will done on an

unannounced, random basis.

Information gathered and program modifications that become necessary will be communicated to

Tetra Tech NUS personnel by the Tetra Tech NUS HSM.

4.7.1 Equipment and Evaluation of Confined Spaces All spaces must be properly evaluated before and during entry operations. Figure 2 specifies the

criteria for equipment inspections that will be maintained on this site to evaluate and support

Confined Space Entry operations.

4.7.2 Confined Spaced Signage Each of these spaces have been (or will be, upon creation) clearly posted with signs stating

“DANGER - PERMIT REQUIRED CONFINED SPACE - DO NOT ENTER” or “DANGER -

CONFINED SPACE - DO NOT ENTER” as applicable.. Unauthorized entry into any of these

spaces is strictly prohibited.

A-V-15

5.0 DEFINITIONS

Acceptable e ntry co nditions - The conditions that m ust exis t and be mai ntained in a confi ned

space in o rder to allow entry and work activities to be performed by personnel. For pu rposes of

this program, this definition will al so reflect those conditions which must be m aintained and must

not be co mpromised. The refore, acceptable entry conditions are defined a s, but not limited to,

the following:

A "hazardous atmosphere" (as defined in this se ction) either does not exist, or it can be

adequately controlle d to allow e ntry. Exam ples of control measure s may includ e

ventilating, purgin g, or i nerting the PRCS, or a combi nation of these measures.

Additionally, the u se of a ppropriate personal protective equipment may be considered a

control measure when other engineering and a dministrative controls a re not fe asible or

are unable to be adequately controlled.

The space t o be ente red ha s b een p roperly i solated. T his inv olves ensuring that all

energy sources have be en identified a nd secured in a zero ene rgy state to the gre atest

possible extent. This is a ccomplished through the u se of ene rgy control measures such

as lo ckout pro cedures, blan king o r bli nding te chniques, dou ble block a nd blee d

procedures, or othe r ap propriate en ergy control methods. This effort must be

documented, and all members a ssociated with th e entry mu st concur that all co ntrol

sources have been identified, tested, and are disabled.

The space to be entered does not contain a material that could engulf an entrant. If such

a mate rial i s involved, a dequate cont rol m ethods su ch as sh oring or slo ping of the

material must be adequately implemented prior to initiation of the entry.

The space to be entere d does not con tain any other se rious hazard potential(s) which

cannot be contained or controlled to the satisfaction of the entry supervisor.

Attendant - An individual stationed o utside on e o r more p ermit spaces who monitors the

authorized e ntrants and who p erforms all atten dant's dutie s a ssigned by this Confine d Space

Entry Program.

Authorized e ntrant - An employee who is auth orized by Tetra Tech NUS to enter a confined

space or a permit required confined space.

A-V-16

Blanking or blinding - The absolute closure of a pipe, line, or duct by the fastening of a solid plate

that completely covers the bore, which ensures no leakage occurs beyond the plate.

Confined space. A confined space means a space that:

Is large enough and so configured to permit an employee to enter and perform work; and,

Has limited or re stricted means for e ntry or exit (for example, tanks, vessels, silo s,

storage bins, hoppers, vaults, pits, etc.); and,

Is not designed for continuous employee occupancy.

Double block and bleed - The closure of a line, duct, or pip e by closing and locking two i n line

valves and b y opening an d locking a drain or vent valve in the line betwee n the two closed

valves.

Emergency - Any occurrence (including any failure of hazard control or monitoring equipment) or

event internal and/or external of the co nfined space and/or pe rmit-required confined space, that

could endanger entrants.

Entry - T he action by whi ch a person passes through an opening into a confined space. Entry

includes ensuing work activities that are performed in the confined space. Entry is considered to

have occurred as soon a s any part of the entrant's body breaks the plane of an opening into the

confined space.

Entry permit - T he written or printed document which is provided by the employer to allow and

control entry into a confined space and/or a permit required confined space. The permit contains

pertinent information regarding the space to be entered.

Entry su pervisor - The p erson re sponsible for dete rmining if acc eptable entry c onditions are

present the confined space and/o r the permit requi red confined space where entry is plan ned.

The Entry su pervisor is al so responsible for authorizing entry, overseei ng entry operation s, and

for terminating the entry as conditions dictate.

Hazardous a tmosphere - An atmosp here that may expos e employees to the ri sk of d eath,

incapacitation, impairment of ability to self rescue, injury, or acute illness from one or more of the

following causes:

A-V-17

Flammable gas, vapor, or mist i n excess of 10 percent of it s lower explosive l imit -LEL

(sometimes referred to as the lower flammable limit - LFL).

Airborne combustible du st at a concentration that meets or exceeds 10 pe rcent of it s

LEL/LFL.

Atmospheric oxygen concentration below 19.5 percent or above 23.5 percent.

Atmospheric concentration of any substance for which a dose or a permissible exposure

limit is established. Also an atmospheric concentration which could impede the entrant's

ability to self rescue resulting in em ployee expo sure and a dverse h ealth effects

associated with that exposure.

Any other atmospheric condition that is immediately dangerous to life or health.

Hot Wor k Permit - The employer's written autho rization to p erform o perations (e.g., wel ding,

cutting, burning, heating, etc.) capable of providing a source of ignition.

Immediately Dangerous to Life or Health (IDLH) - A ny condition which poses an immediate or

delayed th reat to life, or a con dition t hat woul d cause i rreversible adve rse health effect s. In

addition, an IDLH condition includes any condition which would interfere or impede an individual's

ability to escape unaided from a confined space and/or a permit-required confined space.

Inerting - The displacement of the hazardous atmosphere in a permit-required confined space by

introducing a non-reactive gas (such as nitrogen) to such an extent that the resultin g hazardous

atmosphere would be p ushed from th e permit -required confined spa ce rendering that p ermit-

required confined space non-reactive.

Note: Inerted spaces a re still considered h azardous due to the displacement of oxygen.

Typically, inerting a space is followed by the ventilation of that space.

Isolation - The p rocess by which a permit spa ce is re moved from servi ce and co mpletely

protected against the release of energy and material into the space by such means as:

blanking or binding;

misaligning or removing sections of lines, pipes, or ducts;

A-V-18

a double block and bleed system;

lockout of all energy sources, and the reduction of potential energy sources to their zero

mechanical state;

blocking or disconnecting all mechanical linkages.

Line brea king - The inte ntional op ening of a pipe, line, or du ct that is or h as be en carrying

flammable, corrosive, or toxic material, an inert gas, or any fluid at a volume, pressure, or by the

SSO.

temperature capable of causing injury.

Lockout - [As defined by OSHA 29 CFR 1910.147 (b)] The placement of a lockout device on an

energy isolati ng d evice, in acco rdance with a n established procedure, whi ch ensure s that the

energy isolating device an d the equipment being controlled cannot be ope rated until the lockout

device is removed.

Permit required confined space (PRCS). A a confined spa ce having one or more of the following

characteristics:

Contains a h azardous at mosphere, o r po ssesses t he p otential t o contain a hazardous

atmosphere.

Contains a material which has the potential for engulfing an entrant.

Has an i nternal configu ration su ch tha t an entrant entering t he PRCS coul d become

entrapped or asphyxiated by inwardly converging walls or a floor which slopes downward,

tapering to a smaller cross-section.

Contains any other recognized serious safety or health hazard, or by virtue of the task to

be undertaken, may generate unsafe conditions.

Permit system - The employer's written procedure for preparing and issuing permits for entry and

for returning the permit space to service following termination of entry.

Prohibited condition - Any condition in a confined space and/or a permit-required confined space

that is not allowed by the permit during the period when entry is authorized.

A-V-19

Safe Work Permit (SWP) – A SWP is a permit issued by the FOL and/or the HSO. This permit is

used to summarize potential hazards and co ntrol measures associated with a specified task as

identified wit hin a site-specific scope of work. Th e inform ation derived to complete a S WP is

obtained fro m Tabl e 5 -1 of the Site-spe cific healt h an d safety plan and th e in clusion of site-

specific conditions whi ch may impact the afor ementioned ha zards or control measures. The

application as it p ertains to confine d space operations is provided by the in dication of additional

measures required for confined space operations.

Tagout - [As define d by OSHA 29 CFR 1910.147 (b)] The placement of a ta gout device on an

energy isolating device, in accordance with an established procedure, to indicate that the energy

isolating device and the equipment being controlled may not be operated until the tagout device is

removed. It sh ould be emphasized that any ti me tago ut i s employed a s an ene rgy control

measure, it must offer th e same level of p rotection as its en ergy cont rol m easure counte rpart

lockout.

Testing - Th e process by which the h azards that may confront entrants of a permit spa ce are

identified and evaluated. Testing includes specifying the tests th at are to be performed in the

permit space. Details pertaining to testing methods and procedures are discussed in Section 4.4

of this program.

APPENDIX I

TETRA TECH NUS, INC. CONFINED SPACE

ENTRY OPERATIONS

PROJECTS SITES INVOLVING CONFINED SPACE ENTRY OPERATIONS

The frequency that Tetra Tech NUS projects involve both confined spaces in the work area and a

work scope that req uires perso nnel t o actu ally e nter a space is very l ow. This cannot be

interpreted as indicating that the level of concern for a Confined Space Entry Program is not a

priority. In fact, becau se this type of activity is infrequent, the le vel of con cern is g reater. The

non-routine nature of these operat ions inhibit our ab ility to develop and mainta in a high level of

proficiency. Therefore, th e need for a n effective program to con trol or minimize the potentially

severe hazards of confined space entry work is a very high priority.

The written program presented will be used at all Tetra Tech NU S project sites where confined

space entry operations are planned. That program has been developed to provide the SSO with

a standardized tool to serve two purposes:

1. To protect the health and safety of Tetra Tech NUS and subcontractor personnel working in

or near confined spaces.

2. To comply with Federal regulatory requirements.

PERSONNEL RESPONSIBLE FOR PROGRAM COMPLETION

The following persons are available to provide assistance in all elements of this program including

question/conflict re solution and mo dification varia nces. The se persons exe rcise the p rimary

responsibility for the implementation of this site-specific program.

RESCUE SERVICES

The Naval Shipyard Fire and Rescue Department will serve as the identified rescue

service. The rescue service can be obtained at (207) 438-2333. The entry operation will

be coordinated through the rescue service. All pertinent information will be provided

prior to entry. Notification shall take place prior to, and after entry operations cease. CONFINED SPACE INVENTORY/STATUS The following inventory represents the confined spaces at this project site. These

spaces are listed by way of planned entry or proximity. This list will be updated by the

SSO and/or the FOL as necessary.

1) Limited entrance and exit;

movement in the crawl space is restricted.

2) Atmospheric hazard. Potential for high levels of CO if there is a ship and or vehicle activity outside the building

3) Contaminants in soil 4) Rescue equipment

1) Use a strong ladder to enter and exit the space. 2) Check oxygen and CO levels prior to entry. 3) Use of other PPE (coverall, gloves, boot covers, etc.) as per the safe work permit. 4) Use of a body harness and lifeline when performing vertical entries is not considered necessary given the degree of estimated hazard. Ladders will be provided for exit and entrance. Notify rescue personnel of entry schedule.

A copy of this completed permit must be provided to the HSM (M. Soltis) upon completion of the entry.

ENTRIES INTO THE ABOVE IDENTIFIED CONFINED SPACES WILL BE BY WRITTEN PERMIT ONLY. VI) Confined Space Entry Permit The Confined Space Entry Permit will guide and direct field personnel regarding all aspects of the entry by

using the permit as a checklist. It is based on this application that no spaces on the permit be left

unchecked.

The assigned authorized entrant(s) and attendant(s) will complete the Confined Space Entry Permit.

However, entry is not permitted until the Entry Supervisor reviews the permit and signs off.

Figure 1 will be used as the written permit on this site. Permits will be reviewed, issued, and canceled by the

SSO, who will also serve in the role of Entry Supervisor. Permits must be completed before any entry

operations begin. Completed permits will be reviewed with all involved personnel as part of their task-

specific training, and then posted at or near the entrance to the space.

VII) Hazard Monitoring

Spaces will be initially evaluated by the Authorized Entrant and Attendant as follows:

Pre-entry, to determine that satisfactory entry conditions exist

Continuously, if the space cannot be isolated

Periodically, if the space can be isolated (at least once every __ minutes)

The sequence for conducting these evaluations will be (from first to last):

1. Oxygen level

2. Lower Explosive Level (for gases, vapors, mists, or particulates)

3. Toxic gases or vapors

Specific equipment and instrument action levels are specified on the permit.

Information derived from the monitoring activity will be recorded on the Entry Permit. This information will be

used to determine if accep table entry conditions exist and wheth er entry is permitted. The SSO will revi ew

all information collected and authorize entry, if conditions are determine to be acceptable.

All equipment to be used in support of the confined space operation(s) will be inspected by the SSO or d uly

appointed representative, prio r to i nitial u se. In spections will entail a p hysical exa mination and an

operational check. The Confined Sp ace Equip ment In spection Re cord will be u sed to document th ese

inspections. Where appropriate existing inspection records for instance Respiratory Equipment Checklist will

be used in place of the Confined Space Equipment Inspection Record.

IX) Permit Termination

A confined space entry permit can be terminated for a number of reasons. These include, but not limited to,

the following:

Scope of work change

Acceptable conditions within the space change

Time limit expires

Planned activities are completed

Upon termination of an active permit the following steps will take place.

1) The Confine d Space Permit and any other a ssociated pe rmit (Safe Work P ermit, Hot Work

Permit, etc.) or hazard m onitoring results will be copied. The copies will be forwarded to the

PHSO for evaluation.

2) Upon evaluat ion the PHS O will forward the copi ed permits to the HSM for record-keeping and

review. The PHSO will i nclude any relevant co mments for the HSM to be considered during

his/her review.

3) The HSM will maintain the completed permits and associated materials for a period of one year

from the date of issue.

Attendant, Rescue) These records should identify initial and refresher dates and be accompanied by

official Certificates of Training.

- Site Specific Training Documentation of this completed Program.

Medical Surveillance Evaluations

General Requirements and Responsibilities

Only properly authorized and trained personnel will be permitted to participate in entry operations. The Entry

Supervisor (the site Health and Safety Officer) will be responsible for conducting these authorizations and for

ensuring that training requirements are satisfied. A ll persons involved with entry operations will be properly

designated on the Permit. At least one Entry Attendant will be stationed outside of the sp ace at all time s

during any confined spa ce entry opera tion. The identity of the Attendant(s ) wil l be clearly in dicated on the

entry permit. Attendants will not be a ssigned any addition al dut ies that co uld interfere wi th fulfilling their

responsibilities as space Attendants. Multiple spaces will not be monitored by a single attendant. This

type of approach is strictly prohibited.

Emergency rescue operations will be non-entry means only. Emergency procedures will be specified on the

entry permit.

If entry operations will involve the us e of contractor personnel, the Subcontractor Permit Required Confined

Space Program (See App endix 3 of the Tetra Te ch NUS Confined Space Entry Operatio ns Program) must

be completed by the site Health and Safety Officer and maintained onsite.

At the concl usion of entry operation s, the SSO will ensu re that all perso nnel and equipm ent have be en

removed from the space, that a final space evaluation is performed, and the permit will be canceled and filed.

A copy of th e can celed p ermit must b e sent to the Tetra Tech NUS Health and Safety Manag er at the

conclusion of the proje ct, and n ot later than by November 30 for projects where wo rk continues toward the

end of a calendar year in order to facilitate the annual program evaluation process.

Weather may affect the dig. Ensure water pipes are protected during freezing weather, especially if the trench will be left open over night. Rain may cause the side of the trench to slough, which can undermine and break pipes/conduit.

Ensure care when moving trench boxes in and out of trenches so pipes/conduit aren’t damaged by the boxes.

Ensure surface drainage is controlled so that water doesn’t get into the excavation and undermine soil supporting utilities.

Ensure stocked material is kept far enough back (minimum 2 feet) so that material and rocks don’t fall on utilities in the open hole.

Ensure backfilling is done carefully: Re-bed utilities with proper material, filling all voids below. Keep inappropriate material from falling on or being placed in the trench. Be careful when compacting backfill in the two feet directly above the utility.

Keep the as-built utility drawing in the field while the excavation site is open. Take pictures if possible (horizontal alignment and elevations), if known utilities deviate from facility drawings or if utilities are found that are not on facility drawings. Give the modified as-built drawings to the Building/Facility Manager, who will update the drawing database.

Ensure that the equipment operator digs slowly and remains in control.

Decontamination is the process of removing and/or neutralizing site contaminants that have contacted and/or accumulated on equipment. The objective/purpose of this SOP is intended to protect site personnel, general public, and the sample integrity through the prevention of cross contamination onto unaffected persons or areas. It is further intended through this procedure to provide guidelines regarding the appropriate procedures to be followed when decontaminating drilling equipment, monitoring well materials, chemical sampling equipment and field analytical equipment.

2.0 SCOPE

This procedure applies to all equipment including drilling equipment, heavy equipment, monitoring well materials, as well as chemical sampling and field analytical equipment decontamination that may be used to provide access/acquire environmental samples. Where technologically and economically feasible, single use sealed disposable equipment will be employed 'to minimize the potential for cross contamination. This procedure also provides general reference information on the control of contaminated materials.

3.0 GLOSSARY

Acid - For decontamination of equipment when sampling for trace levels of inorganics, a 10% solution of nitric acid in deionized water should be used. Due to the leaching ability of nitric acid, it should not be used on stainless steel.

Alconox/Liauinox - A brand of phosphate-free laboratory-grade detergent.

Decontamination Solution - Is a solution selectedhdentified within the Health and Safety Plan or Project- Specific Quality Assurance Plan. The solution is selected and employed as directed by the project chemistlhealth and safety professional.

Deionized Water (DI) - Deionized water is tap water that has been treated by passing through a standard deionizing resin column. This water may also pass through additional filtering media to attain various levels of analyte-free status. The DI water should meet CAP and NCCLS specifications for reagent grade, Type I water.

Potable Water - Tap water used from any municipal water treatment system. Use of an untreated potable water supply is not an acceptable substitute for tap water.

Pressure Washinq - Employs high pressure pumps and nozzle configuration to create a high pressure spray of potable water. High pressure spray is employed to remove solids.

Solvent - The solvent of choice is pesticide-grade Isopropanol. Use of other solvents (methanol, acetone, pesticide-grade hexane, or petroleum ether) may be required for particular projects or for a particular purpose (e.g. for the removal of concentrated waste) and must be justified in the project planning documents. As an example, it may be necessary to use hexane when analyzing for trace levels of pesticides, PCBs, or fuels. In addition, because many of these solvents are not miscible in water, the equipment should be air dried prior to use. Solvents should not be used on PVC equipment or well construction materials.

Steam Pressure Washinq - This method employs a high pressure spray of heated potable water. This method through the application of heat provides for the removal of various organic/inorganic compounds.

The decontamination processes are typically employed at:

0 Temporary Decontamination Pads/Facilities 0 Sample Locations 0 Centralized Decontamination Pad/Facilities 0 Combination of some or all of the above

The following discussion represents recommended site preparation in support of the decontamination process.

5.1 Decontamination Desiqn/Constructions Considerations

5.1.1 Temporary Decontamination Pads

Temporary decontamination pads are constructed at satellite locations in support of temporary work sites. These structures are generally constructed to support the decontamination of heavy equipment such as drill rigs and earth moving equipment but can be employed for smaller articles.

The purpose of the decontamination pad is to contain wash waters and potentially contaminated soils generated during decontamination procedures. Therefore, construction of these pads should take into account the following considerations

- PedestrianNehicle thoroughfares - -

- Areas potentially contaminated.

Areas where controVcustody cannot be maintained Areas where a potential releases may be compounded through access to storm water transport systems, streams or other potentially sensitive areas.

Pad - The pad should be constructed to provide the following characteristics

5.1.2

Size - The size of the pad should be sufficient to accept the equipment to be decontaminated as well as permitting free movement around the equipment by the personnel conducting the decontamination.

Slope - An adequate slope will be constructed to permit the collection of the water and potentially contaminated soils within a trough or sump constructed at one end. The collection point for wash waters should be of adequate distance that the decontamination workers do not have to walk through the wash waters while completing their tasks.

Sidewalls - The sidewalls should be a minimum of 6-inches in height to provide adequate containment for wash waters and soils. If splash represents a potential problem, splash guards should be constructed to control overspray. Sidewalls maybe constructed of wood, inflatables, sand bags, etc. to permit containment.

Liner - Depending on the types of equipment and the decontamination method the liner should be of sufficient thickness to provide a puncture resistant barrier between the decontamination operation and the unprotected environment. Care should be taken to examine the surface area prior to placing the liner to remove sharp articles (sticks, stones, debris) that could puncture the liner. Liners are intended to form an impermeable barrier. The thickness may vary from a minimum recommended thickness of 10 mil to 30 mil. Achieving the desired thickness maybe achieved through layering lighter constructed materials. It should be noted that various materials (rubber, polyethylene sheeting) become slippery when wet. To minimize this potential hazard associated with a sloped liner a light coating of sand maybe applied to provide traction as necessary.

Wash/drying Racks - Auger flights, driIVdrive rods require racks positioned off of the ground to permit these articles to be washed, drained, and dried while secured from falling during this process. A minimum ground clearance of 2-feet is recommended.

Maintenance - The work area should be periodically cleared of standing water, soils, and debris. This action will aid in eliminating slip, trip, and fall hazards. In addition, these articles will reduce potential backsplash and cross contamination. Hoses should be gathered when not in use to eliminate potential tripping hazards.

Decontamination Activities at Drill Rigs/DPT Units

During subsurface sampling activities including drilling and direct push activities decontamination of drive rods, Macro Core Samplers, split spoons, etc. are typically conducted at an area adjacent to the operation. Decontamination is generally accomplished using a soap/water wash and rinse utilizing buckets and brushes. This area requires sufficient preparation to accomplish the decontamination objectives.

019611/P Tetra Tech NUS, Inc.


Buckets shall be placed within mortar tubs or similar secondary containment tubs to prevent splash and spills from reaching unprotected media. Drying racks will be employed as directed for temporary pads to permit parts to dry and be evaluated prior to usehe-use.

3 09/03

5.1.3 Decontamination Activities at Remote Sample Locations

When sampling at remote locations sampling devices such as trowels, pumpdtubing should be evacuated of potentially contaminated media to the extent possible. This equipment should be wrapped in plastic for transport to the temporary/centralized decontamination location for final cleaning and disposition.

5.2 Equipment Decontamination Procedures

The following represents procedures to be employed for the decontamination of equipment that may have contacted and/or accumulated contamination through site investigation activities.

5.2.1 Monitoring Well Sampling Equipment

5.2.1 .I Groundwater samplinq pumps - This includes pumps inserted into the monitorinq well such as Bladder pumps, Whale pumps, Redi-Flo, reusable bailers, etc.

1)

2)

Evacuate to the extent possible, any purge water within the pump.

Scrub using soap and water and/or steam clean the outside of the pump and tubing, where applicable.

Insert the pump and tubing into a clean container of soapy water. Pump a sufficient amount of soapy water through the pump to flush any residual purge water. Once flushed, circulate soapy water through the pump to ensure the internal components are thoroughly flushed.

3)

4) Remove the pump and tubing from the container, rinse external components using tap water. Insert the pump and tubing into a clean container of tap water. Pump a sufficient amount of tap water through the pump to evacuate all of the soapy water (until clear).

5)

6)

Rinse equipment with pesticide grade isopropanol

Repeat item #4 using deionized water through the hose to flush out the tap water and solvent residue as applicable.

7 ) Drain residual deionized water to the extent possible, allow components to air dry.

8) Wrap pump in aluminum foil or a clear clean plastic bag for storage.

5.2.1.2 Electronic Water Level Indicators/Sounders/Tapes

During water level measurements, rinsing with the extracted tape and probe with deionized water and wiping the surface of the extracted tape is acceptable. However, periodic full decontamination should be conducted as indicated below.

- The solvent should be employed when samples contain oil, grease, PAHs, PCBs, and other hard to remove materials. If these are not of primary concern, the solvent step may be omitted. In addition, do not rinse PE, PVC, and associated tubing with solvents.

Note: In situations where oil, grease, free product, other hard to remove materials are encountered probes and exposed tapes should be washed in hot soapy water.

5.2.1.3 Miscellaneous Equipment

Miscellaneous equipment including analytical equipment (water quality testing equipment) should be cleaned per manufacturer’s instructions. This generally includes wiping down the sensor housing and rinsing with tap and deionized water.

Coolers/Shipping Containers employed to ship samples are received from the lab in a variety of conditions from marginal to extremely poor. Coolers should be evaluated prior to use for

0 Structural integrity - Coolers missing handles or having breaks within the outer housing should be removed and not used. Notify the laboratory that the risk of shipping samples will not be attempted and request a replacement unit.

0 Cleanliness - As per protocol only volatile organic samples are accompanied by a trip blank. If a cooler’s cleanliness is in question (visibly dirty/stained) or associated with noticeable odors it should be decontaminated prior to use.

1) Wash with soap and water 2) Rinse with tap water 3) Dry

If these measures fail to clean the cooler to an acceptable level, remove the unit from use as a shipping container and notify the laboratory to provide a replacement unit.

5.2.2 Down-Hole Drilling Equipment

This includes any portion of the drill rig that is over the borehole including auger flights, drill stems, rods, and associated tooling that would extend over the borehole. This procedure is to be employed prior to initiating the drilling/sampling activity, then between locations.

It is recommended that a follow up sample be collected during the execution of the project to insure those conditions do not change. Lastly, rinsate samples collection may be driven by types of and/or contaminant levels. Hard. to remove contaminants, oildgreases, some PAHs/PCBs, etc. may also support the collection. of additional rinsates due to the obvious challenges to the decontamination process. This is a field consideration to be determined by the FOL.

Section 1

Management Requirements for PCB-Containing Wastes

This document is an addendum to the Waste Management Plan, Middle River Complex, Middle

River, Maryland (WMP) prepared by Tetra Tech, Inc. (Tetra Tech) on May 11, 2010. The WMP

addresses management of the potentially contaminated wastes generated as part of field

investigations at the Middle River Complex (MRC) in Middle River, Maryland. This addendum

addresses the handling, storage, labeling, testing, and disposal of polychlorinated biphenyls

(PCB)-containing wastes that will be generated during implementation of Interim Remedial

Measures (IRM) at the Tax Block E storm drain system of the MRC. All provisions of the WMP

and this addendum will be followed during the project.

1.1 PCB-CONTAINING WASTES

Sediment sampling completed in 2009 indicated PCB concentrations greater than 50 mg/kg at two

locations in the southern portion of Block E in the Outfall 05 storm drain system: IL-18 and MH-

3. Therefore, in accordance with 40 CFR 761, sediment/debris (including bricks from

inlets/manholes)/soil and water removed from the storm drain segments extending from MH-4 to

both discharge points on Outfall 05, between IL-18 and IL-19, and in the west extension from IL-

18 will be considered PCB-containing material controlled under the Toxic Substances Control Act

(TSCA) and will be segregated from other waste and stored in lined watertight roll-offs. These

containers will be properly labeled and stored in the waste drum accumulation area of Block E.

Handling, storage, labeling, testing and disposal will be in accordance with TSCA (40 CFR 761)

requirements as detailed in the following sections.

Other sediment/debris will also be stored in lined watertight roll-offs for testing and disposal per

the WMP. All sediment/debris/soil collected will be screened with a radiation survey meter during

collection. If radioactivity above background levels is detected, those materials will be segregated

for consideration of final disposition.


1.2 HANDLING AND STORAGE

Sediment/debris (including bricks from inlets/manholes)/soil removed from the Outfall 05 storm

drain system segments specified in Section 1.1 will be stored in lined watertight roll-off

containers. Water removed from the draining and cleaning of these segments and sediment

dewatering will be stored in non-segregated frac tanks (water is a separate phase with no

investigation results above 50 mg/L; all water generated during the cleaning of all drain segments

will be considered PCB-impacted). Water resulting from the sediment/debris dewatering will be

collected and transferred to the water frac tanks for subsequent disposal as PCB-impacted water or

on-site treatment if a permit is obtained from Baltimore County.

The roll-off containers will be staged near the work areas and relocated as necessary for efficient

loading. Once the IRM is completed in the designated segments, the roll-offs will be stored in the

waste drum accumulation area (concrete pad in the northwest area) of Block E. These containers

will be properly marked as detailed in Section 1.3. During the duration of the project field work,

Tetra Tech field personnel will conduct a daily visual inspection of the containers and ensure that:

• The containers are staged on continuous smooth and impervious surfaces above the 100-

year flood water elevation;

• The containers are closed to prevent rain water from entering; and

• No drain valves or other openings allow liquids to flow from the containers.

Once the field work is completed, the containers will be inspected once per week until they are

removed for off-site disposal.

1.3 LABELING

The roll-offs containing the PCB-containing wastes will be properly marked. A “Large PCB

Mark” or label will be placed on each exterior side of the containers so that the labels can be easily

read by any person inspecting or servicing the containers. In accordance with 40 CFR 761.45, the

labels will be at least six inches on each side, consist of letters and striping on a white or yellow

background and be sufficiently durable. The sample label to be used is provided in Appendix A.

In addition, each container will have a label specifying the section of pipe, inlet and manhole from


which the PCB-containing sediment/debris (including bricks from inlets/manholes)/soils and water

were removed.

1.4 TESTING

One grab sample per each roll-off with PCB-containing wastes will be collected and submitted to

TestAmerica, Inc. (TestAmerica) for PCB analysis by SW 846, USEPA Method 8082, Toxicity

Characteristics Leaching Procedure (TCLP) organics/inorganics analysis, and Resource

Conservation and Recovery Act (RCRA) characteristics ignitability, corrosivity, and reactivity

analyses. One hundred percent (100%) duplicate blind samples for PCB analysis by SW 846,

USEPA Method 8082 will be taken to verify laboratory results. The samples will undergo Level

IV data validation procedures in accordance with USEPA Region III protocols. This waste will

remain designated PCB-containing even if PCB results are less than 50 mg/kg.

In addition, one grab sample per each roll-off with sediment/debris/soil will be collected and

submitted to TestAmerica for analysis of gross alpha and beta radioactivity by SW 846 Method

9310 modified, uranium isotopes by United States Department of Energy (DOE) Method A-01-R,

and total strontium by DOE Method SR-03-RC. One grab sample per each roll-off with

sediment/debris/soil will be also collected for asbestos analysis by polarized light microscopy

(PLM)/USEPA Method 600.

1.5 DISPOSAL

Upon receipt of the analytical data, the PCB-containing wastes will be profiled and removed for

proper off-site disposal in accordance with federal, state, and local regulations at a Lockheed

Martin-approved facility.

Clean Harbors Environmental Services (Clean Harbors) will be retained to transport designated

PCB-containing sediments and any other sediment/debris (including bricks from

inlets/manholes)/soil with a PCB concentration greater than 50 parts per million (ppm) to the

CWM Chemical Services (WMI Facility) in Model City, New York, the EQ Belleville facility in

Michigan or an approved alternative.


Sediment/debris (including bricks from inlets/manholes)/soil that is not designated as PCB-

containing and has a PCB-concentration less than 50 ppm will be disposed at the Clean Harbors

Twinsburg, Ohio facility, the WM Waynesburg, Ohio facility or an approved alternative.

All water generated as part of the IRM work will be considered PCB-impacted. Clean Harbors

will also be retained to transport and properly dispose of the water (assuming PCB concentrations

are less than 50 mg/L) at its Baltimore, Maryland facility or an approved alternative if on-site

treatment and discharge to the local publicly owned treatment works (POTW) is not approved by

Baltimore County. If on-site treatment and discharge is approved, we assume that testing for PCBs

and other parameters will be required for every 20,000 gallons discharged based on the permit for

Block B discharge dated November 1, 2010.

Sediment/debris containing asbestos and/or radioactivity above background levels will be

disposed at a Lockheed Martin-approved facility in accordance with all local, state and federal

regulations.

Documentation of proper disposal will be maintained and will include the analytical data,

manifests, and shipping documents.

1.6 EQUIPMENT DECONTAMINATION

Equipment that comes in contact with PCBs will be decontaminated in accordance with 40 CFR

761 requirements. The washes/rinses will be followed up with wipe tests for PCBs. The liners in

the segregated PCB-containing roll-off containers will be disposed together with the PCB-

containing sediments/debris (including bricks from inlets/manholes) and soils. The frac tanks

containing the PCB-impacted water will be triple-rinsed with tap water and the rinse water will be

disposed together with the PCB-impacted water either at the Clean Harbors Baltimore, Maryland

facility or with approval from Baltimore County to the local POTW after on-site treatment.

Documentation of the decontamination procedures will include photographs and video clips.

repairing or replacing inlets and manholes, as necessary. This plan describes how Tetra Tech will

comply with applicable federal, state and local environmental regulations.

Erosion control measures will be implemented in general accordance with the 1994 Maryland

Standards and Specifications for Soil Erosion and Sediment Control and the requirements of

Baltimore County Department of Environmental Protection. Less than 500 square feet of

vegetated surface will be disturbed by this project so local and state permits are not required.

However, the Baltimore County Soil Conservation District Sediment and Erosion Control

Standard Plan (included in Appendix A) will be completed and followed.

1.1 GENERAL APPROACH

Tetra Tech will use erosion control measures to prevent soil erosion and transport of sediments

caused by the IRM construction activities and prevent sediment from entering storm sewer system

inlets and structures. Measures taken to control erosion and sedimentation shall be adequate to

ensure that sediment is not transported to or from the site by a storm event to the Block E storm

sewer system outfalls. Erosion control measures must be in place prior to construction activities

commencing.


1.2 SELECTION OF CONTROL MEASURES

The selection of erosion and sedimentation control measures will be based on assessments of site

conditions and how storm events may contribute to erosion. Tetra Tech will install temporary silt

fence and/or hay bales to mitigate erosion and sedimentation. The approximate location of the

erosion control structures is shown on Figure 1-1. Additional erosion control will be provided as

needed.

1.2.1 Silt Fences

Silt fences will be used to filter sediment out of runoff water before it is discharged. Silt fences

will be erected around each inlet and manhole associated with the Block E storm sewer system

using a 20-foot radius or an alternative configuration based on surrounding land use and

topography. Silt fences will be inspected daily and after periods of rainfall of ½ inch or greater.

The silt fences will be cleaned on a regular basis and any defects will be repaired immediately

after they are discovered. While individual inlets or manholes are being repaired or replaced, the

storm sewer pipe at that location will be plugged or will have a bypass pipe section installed to

prevent sediment from entering the storm sewer. Silt fences will remain in place after the IRM

work is completed.

1.2.2 Hay Bales

Hay bales will be used as a temporary berm, diversion, or barrier to help contain soil/sediment

onsite by catching and filtering runoff from the site. Hay bales will be used if areas are created on-

site that could potentially cause runoff of sediment. Hay bales will be laid on their side (hay in bail

is parallel to ground surface, i.e., cut ends are not on the top of the bail) and staked in place with

either wooden or metal stakes. The stakes will be driven through the bale and at least 1-foot into

the ground. Hay bales will be inspected on a regular basis and repaired or replaced when damaged.

1.2.3 Mulching and Seeding

In accordance with Specification #02275 (Appendix C of the Design Report), seed and mulch will

be placed in all disturbed vegetated areas within 14 days after the completion of the IRM work.

The seed will be monitored for one complete growing season provided that the subject areas are


not utilized for storage, continued development or construction activities performed by others

within the defined timeline after it is planted. Any areas that exhibit insufficient vegetation during

the initial one year growing period will be reseeded.

Wood fiber mulch may only be used in seeding season where the slope does not exceed 10% and

grading has been done to promote sheet flow drainage. Areas brought to finished grade during he

seeding season shall be permanently stabilized no later than 14 days after establishment. If work

areas are brought to finished grade during the months of November through February, and

permanent stabilization is found to be impractical, temporary seed and anchored straw mulch will

be applied to disturbed areas. The final permanent stabilization will be applied by March 15 if

ground and weather conditions allow.

1.3 VEGETATION

Silt fences and hay bales will remain in place until vegetation is established, in an effort to protect

the disturbed soils from erosion. Once areas are mulched and seeded, traffic over those areas will

be minimized to prevent disturbance while the vegetation is being established. During dry periods

the seeded areas will be watered to help promote growth of the vegetation. Ground vegetation

shall be retained and protected wherever possible.

1.4 SITE ACCESS ROUTES AND DECONTAMINATION PAD

Main access to Block E will be through the security checkpoint at Gate A. For more efficient and

less disruptive access, Tetra Tech will request to access Block E through Gate D. Access to the

outfalls will require gate access from North American Electric, Inc., which is located west of

Block E across Chesapeake Park Plaza. Access to the IRM staging area on Block E will be

through the northeast corner of Block E. A decontamination pad will be setup at the construction

staging area to allow trucks and vehicles to clean off before exiting the site. The decontamination

pad will be constructed in accordance with the Site and Temporary Facilities Plan. Mud/sediment

on the exterior of trucks and vehicles will be removed by sweeping and brushing and transferring

the mud to the appropriate sediment/debris collection container.


1.5 MATERIAL STOCKPILES

Contaminated material stockpiles (debris and soils only), if placed outside collection containers,

will be placed on a layer of 40-mil LLDPE to prevent cross contamination of the surface soils. A

containment berm will be utilized around the perimeter of the stockpile to contain any water that

comes into contact with the contaminated soil and prevent it from migrating off of the containment

pad. Material stockpiles will be covered with 6-mil poly sheeting to prevent sediment transport

from stockpile areas. The poly sheeting will be secured (i.e. weighed down) using sandbags and/or

large rocks.

1.6 MAINTENANCE

Tetra Tech will maintain and repair silt fencing and other erosion controls as needed until

vegetation is fully established. Once erosion controls are no longer needed the controls will be

removed from the site.

Construction Methodology Plan


Construction Methodology Plan to support implementation of Interim Remedial Measures (IRM)

at the Tax Block E storm drain system of the Middle River Complex in Middle River, Maryland.

This plan describes the means, methods and sequences for performing the sediment and debris

removal from the drain pipes, inlets and manholes as well as other required work for the IRM.

1.1 IRM CONSTRUCTION

1.1.1 Pre-Construction Walkthrough and Work Area Breakdown

A pre-construction walkthrough of the entire lengths of the Block E storm drain drainage pipes

will be conducted prior to construction of the IRM. All inlets and manholes will be visually

inspected to document any changes from the June 2009 storm drain survey observations, which

are summarized in Table 3-1 of the Design Report. The inlets and manholes identified in 2009 as

needing repair or replacement are listed in Table 3-2 of the Design Report. Both tables will be

updated by adding a column with the pre-construction observations.

Plugs for each outfall will be procured for use during storm drain cleaning. Each plug will be

provided with capability to drain accumulated water and pressure gages for leak detection.

1.1.2 Storm Drain System Cleaning

The base crew will consist of a cleaning operator and video inspection technician equipped with a

jet/vacuum truck and mobile closed-circuit television (CCTV) truck. At the start of each day a

tailgate safety meeting will be held by the crew to review the expected job hazards. All work will

be done from above ground except in those instances where access to a drainage pipe is limited

and it is necessary for confined space entry. In those instances, structures will be entered in

accordance with Occupational Safety and Health Administration (OSHA) procedures for confined

space entry.


As indicated in the previous section, the cleaning work will begin with the Outfall 05 drain line

and associated inlets and manholes, then continue with the Outfall 08 system, and end with the

Outfall 06 line. The work will progress according to the pipe segments listed in Table 3-3 and

shown in Figures 2-3 to 2-5 of the Design Report.

During rainfall events, cleaning work will generally be suspended for the day. Work may continue

during light rain as long as the storm event does not surcharge the pipe segment being cleaned and

flood the drainage.

The cleaning tasks will be as follows:

• Remove sediment and debris from the inlets and manholes with a jet/vacuum truck or by hand and contain the solids into an open top watertight roll-off container. On-site fire hydrants will be used for water supply.

• Jet clean the drainage pipe and remove the solids and liquids with a jet/vacuum truck and contain in an open top watertight roll-off container and fractionation (frac) tank. Drainage pipes will be cleaned only after all structures are cleaned. Sediment and wastewater containers will be relocated as needed.

• Video inspect the drainage pipe with CCTV cameras to provide verification that the pipes have been cleaned.

All cleaning and video inspection activities will begin at the farthest upstream portion of the

drainage system segment and work in a downstream direction. A plug will be installed at the outlet

of the first downstream structure. The plug will be inserted into the line and expanded. Clean

water will be used to conduct a leak check confirming that the plug is functional. A pressure gauge

will be attached to the plug. The gauge will be checked every two (2) hours during cleaning

activities with pressure readings documented to confirm the plug did not leak.

The cleaning operation will involve inserting the jet nozzle into the downstream structure and

propelling it towards the upstream structure. As the nozzle is pulled back, liquid and solid waste

flow will be vacuumed up into the jet-vacuum truck. All sludge, dirt, sand, rocks, grease, roots and

other solid or semisolid material resulting from the cleaning operation will be removed at the

downstream manhole of the section being cleaned. Passing material from manhole section to

manhole section will not be permitted. As cleaning proceeds to upstream segments, decisions will

be made regarding the continued usability of each drain segment. If lines are damaged or filled

with material such that cleaning is not possible, those segments will be abandoned by plugging


with concrete grout at the downstream end. The abandoned drain and associated inlets and

manholes would then be removed in the planned Block E excavation project.

Once the debris body of the vacuum truck is full, the contents will be transported and dumped into

a watertight roll-off container. When liquids accumulate above the half way mark in the roll-off

container, they will be removed with a vacuum truck and pumped into a frac tank. The discharge

hose from the truck to the roll-off and from the roll-off to the frac tank will be secured by rope and

the operator will monitor the hose during the transfer. All hose quick couplings will have locking

pins for use during transfers. If any leak is observed, the transfer will be stopped and the leaked

material will be adsorbed for disposal. Field forms will be updated with the sediment and water

levels in each roll-off at the beginning, middle, and end of each work day. The storm drain lines

will be cleaned to 95%. Concrete or chemical debris that may be affixed to the pipes will not be

removed with the industry standard, conventional cleaning equipment that will be used.

After a pipe segment is cleaned, the mobile CCTV truck will be positioned at the upstream

structure and a robotic crawler camera equipped with a multi-angle lens will be inserted into the

drainage pipe and video inspect the downstream structure. During the video inspection, there will

be onscreen information such as date, upstream structure number, downstream structure number,

as well as a continuous footage read out to track the camera's location. All observations will be

recorded on a hard drive and an audio commentary will accompany the video inspection.

Computer generated television inspection reports created with Flexidata software will be produced

on a daily basis. This data will be entered into a Windows-based computer database. All photos

and video clips of the defects and observations will be contained in this database. Once all

cleaning and video inspection activities are complete, the plug will be removed and the operation

moved to the next upstream pipe segment. This procedure will be repeated until the last pipe

segment is reached.

The discharge pipes (24”-32” in diameter) for Outfalls 05, 06 and 08 will be plugged using the

following procedure when any pipe segment is being cleaned. All outfalls will be plugged due to

the interconnections of the drain lines.

• At the start of each cleaning day each outfall pipe will be inspected prior to inserting the plug to make sure nothing interferes with the plug making a tight seal against the pipe.


• The plug will be a “flow through” type with a drain valve installed on the downstream side of the plug. The plug will be inflated to the pressure recommended by the manufacturer. A gauge will be included with each plug and will be monitored every two (2) hours during the work day.

• The plug will remain in place during all cleaning activities. At the end of the day the plug will be removed. Residual water accumulated on the upstream side of the plug will be removed prior to the plug being removed.

• The water will be removed by attaching a vacuum hose to the drain valve.

1.1.3 Repair/Replace Inlets and Manholes

Manholes and inlets will be repaired or replaced as indicated in Table 3-2 of the Design Report

and as necessary per field conditions. Repairs will be performed as a whole once cleaning of the

Block E storm drain system has been completed. Any inlets or manholes on unusable pipe

segments will not be repaired. The repairs and replacement work will be completed taking care not

to allow debris to drop into the cleaned drainage system. A typical detail of the manholes/inlets is

provided in the design plans. Required repairs to these structures vary and cannot be completely

determined until each structure is cleaned. Repairs will be made using brick, concrete, grout and

cast iron frames and covers with as needed crushed stone backfill and concrete, asphalt or

vegetative surface finishes to return the structure to original or better condition for usage. All

repairs will be documented in tables, as-built drawings and photographs. In accordance with the

project’s Health and Safety Plan (HASP), a confined space entry permit will be obtained and all

confined space entry procedures will be followed if it is necessary to enter manholes/inlets.

1.1.4 On-Site Water Treatment and Discharge

Tetra Tech is investigating the possibility of on-site treatment and discharge to the POTW as an

alternate wastewater disposal method. This alternative would involve mobilization, and operation

of a 100-gallon per minute system with bag filters and granular activated carbon to treat up to

20,000 gallons per day. The treatment system would treat water by filtration and carbon

adsorption every one to four days to empty the frac tank(s) used to contain the generated water.

The treated water would then be transferred to a post-treatment holding (frac) tank for testing prior

to discharge to the approved discharge manhole, which will be clearly marked for proper

identification. If discharge to the sanitary drain is approved, Tetra Tech will prepare an addendum

to this Design Report to provide operation details for the system, supervision by an operator

licensed by the Maryland Department of the Environment (MDE), filters, carbon, generator,


fuel/fuel tank, and associated wastes (spent bag filters and carbon). Requirements for system

operation will include daily inspection of all hose/piping connections and full-time observation of

the system during operation. The addendum will include field forms to document volumes of

water treated with the system. The addendum will also discuss laboratory analyses required by

Baltimore County; Tetra Tech assumes testing for polychlorinated biphenyls (PCBs) and

polycyclic aromatic hydrocarbons (PAHs) and other parameter will be required for every 20,000

gallons discharged based on the permit for Block B discharge dated November 1, 2010.

1.2 POST-CONSTRUCTION ACTIVITIES

Post-construction activities will consist of site restoration, post-construction land survey, waste

disposal, preparation of the final site remediation report, and monitoring and maintenance of the

restored areas and drainage system. The post-construction survey will be performed as discussed

in Section 3.2.4 of the Design Report to confirm site features and elevations are consistent with

pre-construction conditions. The other post-construction activities are detailed in the subsequent

sections.

1.2.1 Site Restoration

Upon completion of the IRM activities, all disturbed areas will be restored to approximately pre-

existing grades. The paved and/or areas covered with concrete disturbed by the IRM work will be

restored to pre-existing state as documented in the pre-disturbance video. The concrete for the

structures directly affected by the cleaning work will also be replaced. Seed and mulch will be

placed in all disturbed vegetated areas. A post-construction walkthrough will be conducted and a

post-cleaning video survey of selected portions of the Block E drainage pipes will be taken to

document the site restoration activities and ensure all manhole covers or inlet grates are back on

their respective structures.

The restored areas will be monitored and maintained for one complete growing season provided

that the subject areas are not utilized for storage, continued development or construction activities

performed by others within the defined timeline.

1.2.2 Drainage System Maintenance

Maintenance of the drainage system capacity will be limited to (1) utilization and maintenance of

sediment control measures installed during the cleaning phase (e.g., silt fence installed around all

inlets); and (2) replacement activities including additional/new sediment control measures

following completion of the IRM. The Block E storm drain system will be maintained by

Lockheed Martin Corporation Properties, Inc. (LMCPI).
