Project Specifications

Project Approved Work Plan

At the request of the government organizations managing this site Charter is providing this

closure report for the work performed from May 6 2013 to September 20 2013 This work is a

continuation of the initial remediation effort performed by Charter from April 11 2011 to

January 11 2012 as well as the additional remediation performed from September 3 2012 to

November 8 2012

2 Introduction

21 Phases I amp II

The Callahan Mine Superfund Site is located off Cape Rosier Road and Old Mine Road in the

Town of Brooksville Maine The site was formerly the location of a zinccopper open‐pit mine

It was mined sporadically from the late 1800rsquos to the 1970rsquos The most extensive open‐pit

mining operations started in 1968 and ran until 1972

In 2011 Charter initially mobilized to the Callahan Mine site to perform the remediation of PCB

impacted soils at the Former Mine Operations area removal and relocation of lead and arsenic

impacted soils from within the residential areas and associated restoration work as well as the

relocation of the Ore Pad material to the Tailings Impoundment and associated geotechnical

investigations

Following a sample program implemented by the EPA in the fall of 2011 new areas of PCB

contamination were discovered within the Former Mine Operations area The Maine DEP and

CES developed a new scope of work for the approach to remediation of these areas Plans and

specs for this new scope were issued to Charter in the fall of 2012 Charter remobilized to the

site in the fall of 2012 to perform the remediation of these additional areas Charterrsquos scope of

work under this phase of work included earthmoving and sitework related tasks Engineering

survey sampling and characterization efforts were performed by CES in conjunction with the

Maine DEP Remedial efforts were performed under the direction and supervision of the Maine

DEP as well as CESrsquos full time on site representative

The remediation efforts performed under this Phase of work included the following

Construction of a drainage swale and other site features to control storm runoff in the

Former Operations area site access roads and other areas of disturbed soil on site

Excavation and loading of PCB‐contaminated soils from within the former Callahan Mine

Operations area Depending on contamination levels the soils were shipped to landfills in

Model City New York Norridgewock Maine or relocated on site

Construction of a stockpile area and cap for PCB soils with contamination levels from 1‐10

ppm within the previously constructed Ore stockpile located at the Tailing Impoundment

At the completion of this phase of work Zones 1 and 2 had been remediated in their entirety

and the associated PCB impacted soils where appropriately shipped off site for disposal or

relocated to the Tailings Impoundment stockpile area The stockpile at the Tailings

Impoundment was also covered with geotextile and a cap of former Ore Pad material was

placed over the 1‐10ppm PCB impacted soils Following the completion of these tasks Charter

demobilized equipment manpower and temporary facilities from the site

22 Phase III

In May of 2013 Charter remobilized to the site to continue remediation efforts in Zones 3 amp 4

Other activities also planned under this phase of work included

Perform repairs to the boat ramp previously installed at Lot E as well as the septic system at

Operations area at Zones 3 amp 4 Depending on contamination levels the soils will be shipped

to landfills in Model City New York Norridgewock Maine or relocated on site

Construction of an additional stockpile area and cap for PCB soils with contamination levels

from 1‐10 ppm within the previously constructed Ore stockpile located at the Tailing

Impoundment

Restoration of the Former Mine Ops area following the completion of remediation of Zones 3

amp 4 This is to include the placement of onsite organic materials to promote growth of

vegetation as well as construction of various erosion control and drainage features

The following sections will detail the work performed at the site from May 6 2013 to September

20 2013 The work was performed per the plans and specifications provided and in accordance

with the approved Work Plan and Work Plan Addendum which was developed to document site

observations provide a description of our planned approach and outline the work sequence

3 Residential Lot Repairs

During Charterrsquos initial week on site during this phase of work prior to the start of excavation

activities at the Former Mine Ops repairs were performed at two of the Residential lots that

were remediated under the first phase of work in 2011

31 Lot E Boat Ramp

Since the installation of the Boat Ramp at Lot E observations were made by the Maine DEP and

CES that material placed at the end and sides of the ramp were being washed out by the heavy

current produced from Goose Falls during tide changes

To remedy this situation additional large rip rap was placed at both sides of the ramp by Charter

in an effort to minimize tidal effects on these areas The material was placed with a PC300

excavator Any disturbance to the boat ramp landing that was caused by equipment being

utilized during this work was restored prior to Charter removing equipment from this area

Additionally at the request the Maine DEP and CES Charter also placed additional rip rap at the

base of the Boat Ramp prior to demobilization from the site to ensure that the potential for

washouts in this area had been minimized to the greatest extent possible utilizing practical

means and methods and on site equipment

32 Lot A Septic System

Following the repair of the Boat Ramp Charter also provided manpower and equipment to

repair the effluent septic line from the dwelling at Lot A Over the previous summer season the

residents at Lot A had reported poor performance of their septic system Upon further

inspection by a local plumbing contractor it was determined that a section of the PVC pipe

which ran from the dwelling to the septic tank had settled and was not allowing proper effluent

flow in the pipe

The first step in defining a remedy for this situation was to excavate the pipe run in its entirety

from the dwelling to the septic tank Following excavation of the pipe run it was determined

that the appropriate course of action would be to install new frac34rdquo crushed stone bedding

material set the proper grade and pitch and replace the pipe run in its entirety In addition it

was also determined that the pipe passing through the field stone foundation would have to be

removed and replaced reset to ensure that the pitch of the pipe was adequate and consistent

throughout the run from the dwelling to the tank The PVC cleanout within the dwelling was

also reconfigured to accommodate this modification

This work was performed by Charter in conjunction with Robert L Gray Plumbing and Heating

who has extensive knowledge of the dwelling and local plumbing codes Excavation was

performed by Charter utilizing a mini excavator Digging was also performed by hand when

necessary Following the installation activities the excavation was backfilled and topsoil that

was stripped at the start of the repair was re‐spread Re‐establishment of grass in the affected

area was handled by a local landscaper contracted by the Maine DEP

4 Environmental Management

41 Erosion and Sediment Control

Erosion and Sedimentation (EampS) controls were installed in compliance with the State of Maine

Department of Environmental Protection Best Management Practices (BMPs) and the approved

work plan Additional hay bales erosion control mulch silt fence coir logs and stone for check

dams was delivered to the site and installed as needed to ensure that existing and proposed EampS

controls could be maintained and repaired as needed

Initial BMPs installed to control surface storm water erosion and sedimentation included but

was not limited to

E amp S Control Improvements at the Tailings Impoundment Stockpile Area

In an effort to control erosion and sediment transportation in the area of the 1‐10 ppm PCB soil

stockpile area a drainage swale was constructed on the western edge of the proposed stockpile

area The swale was constructed prior to any construction of the stockpile area being

performed

The swale started at the main site access road and proceeded to the north north east along the

western edge of the Ore material stockpile placed at Tailings during the 2011 remediation work

Stone check dams were also installed as required over the length of the swale The swale layout

is also show on drawing C‐SP02 provided to Charter by CES

The swale transition from the previously stockpiled Ore material to Tailings was constructed

under the direction and supervision of the Maine DEP and CES This transition area was

constructed by first re‐grading existing ore material with an excavator then lining this area of

the swale with onsite HDPE liner and placing rip rap over the liner The liner material was cut

into sections and shingled to prevent backflow of water under the liner A plunge pool was also

constructed at the base of the rip rapped slope From the plunge pool the swale was continued

to connect to an existing swale that was constructed on the Tailings during the 2011 work

Excavation performed on Tailings was done with a mini excavator to minimize the potential

impact to the underlying Tailings material

Following completion of the swale groundwater was observed exiting the wooded slope up

gradient of the northern end of the swale In an effort to direct this water into the swale and

prevent the potential for uncontrolled erosion and sediment transport a lined and rip rapped

extension of the swale was constructed extending to the west to the edge of the wooded area

where the groundwater had been observed exiting the slope

Site Access Road Improvements

In conjunction with the installation of the drainage swale discussed above there were also

improvements and modifications made to the clean site access roads in multiple areas around

the site

Improvements started with the road leading from the main site access road down to the 1‐10

ppm PCB soil stockpile at the Tailings Impoundment This included the installation of a crossing

over the new drainage swale This crossing was constructed with 6rdquo stone at a depth sufficient

to allow storm runoff to pass through the stone and facilitate rock truck traffic to travel over the

stone without damaging the swale Rip rap was also added to the road up gradient from the

swale crossing to improve rock truck access over a historically wet area

Site access road improvements were also made in the former Mine Ops area This included the

use of clean gravel to construct a truck turnaround in Zone 2 so that trucks waiting to be loaded

with soil for offsite TampD could be staged more effectively Lastly the existing site access road

was also extended from the northern edge of Zone 3 to CESrsquos decontamination area for better

access to remediation areas

A figure showing approximate locations of clean roads constructed through Mine Ops can be

found in Appendix G

1‐10 ppm PCB Soil Stockpile at the Tailings Impoundment

BMPs were used to control erosion and sedimentation during the placement of the 1‐10 ppm

PCB impacted soils within the stockpile at the Tailings Impoundment Ore cover material that

was excavated for the placement of the additional 1‐10 material was cast upslope into a berm

between the containment cell and swale discussed in previous sections The berm of displaced

Ore material remained in place until it was utilized in the capping operations

Relocated 1‐10 ppm PCB impacted material was graded to a 10 slope at lower elevations and

transitioned to a 31 slope near the top of the stockpile to shed any storm water that fell

directly on the material During construction the toe of the slope of the 1‐10 ppm PCB soils was

also kept below the grade of the surrounding Ore material to prevent any runoff or sediment

from exiting the containment cell

In addition to the practices listed above the access roads leading to and from this stockpile area

were maintained on a regular basis to keep mud tracking and associated sediment transport to a

minimum

Construction Material Stockpiles

The stockpile area built for incoming construction materials during the 2012 phase of work

located between the Former Mine Operations area the Tailings Impoundment was maintained

for this phase of work Large stockpiles of clean materials were not kept on site to keep the

potential for erosion to a minimum No erosion was encountered in this area over the duration

of this phase of work

Figure 1 Contractor Laydown Stockpile Area

Contractor Laydown Areas

The stone pad previously installed at the jobsite trailer and conex boxes to control mud in the

area was kept and maintained as needed during the duration of the work The laydown area

for Construction Material Stockpiles (as shown above) was maintained for this phase of the

Project Erosion and sedimentation controls were as noted above

Charter maintained and improved upon the EampS control measures listed above as necessary to

ensure that erosion and sediment was controlled throughout the course of the project Charter

inspected these BMPs on a daily basis

42 Water Treatment

Charter installed and maintained an onsite water treatment system during this phase of work

The water system was utilized for the dewatering of active excavation areas and removal of soil

sediment that could potentially contain PCBrsquos The system consisted of a 10000 gallon frac tank

to be used for water storage and settlement of suspended solids and (2) bag filter units plumbed

in series The first of the bag filter units contained a 25 micron filter the second bag filter unit

contained a 1 micron filter

Following treatment the water was sampled by CESrsquos on site engineer to ensure the treatment

systemrsquos effective operation Water was discharged to the small detention basin located

between Zones 2 and 3 which also contained a culvert to connect the basin to the swale that

was blasted through the area of bedrock during the 2012 work The effluent hose was

discharged into an area of filter fabric to prevent any additional erosion from within the basin

The effluent hose was later discharged directly into the culvert due to issues with water

infiltration in the area

43 Dust Control

A 2400 gallon water truck was used to provide dust control to the site Water for dust control

activities was pumped from Goose Pond for use in the Former Mine Operations road and site

access road The water truck was also used to supply pressure washers as needed for ledge

cleaning and decontamination operations

5 Health and Safety Site Control

Throughout the duration of the project Charter adhered to the approved Accident

PreventionSite Safety and Health Plan (HASP) All subcontractors and other personnel entering

and working on the site were also briefed on the HASP and potential safety hazards associated

with ongoing site activities Weekly safety meetings were also held on various subjects with

Charter personnel

Control of PCB Contaminated Excavation Areas

Contaminated soils were controlled through the use of site control zones which included an

exclusion zone (Mine Operations) a contamination reduction zone (southern end of Mine Ops)

and a support zone (lay down area between Mine Ops and the Tailings Impoundment as well as

the northern laydown area with the jobsite trailer and conex boxes) The extent and relative

positions of the control zones changed during the progressive stages of the excavation areas

during the project The limits of these control zones were adjusted as site‐specific conditions

relative to location and size of the excavation area(s) became defined The control zones were

established using caution tape paint or flagging to identify that these areas were exclusion

Charter personnel required to enter contaminated areas were outfitted with modified Level D

PPE This consisted of a Tyvek suit latex or rubber gloves safety glasses and a hard hat PPE

levels were modified as needed by the task that was being performed Each worker required to

enter contaminated areas was also issued a dedicated pair of rubber boots to be used only in

the exclusion zones to further prevent tracking of contaminated soils When not in use these

dedicated boots were kept in a container within the exclusion zone and at the projectrsquos end

these boots were sent off site for disposal with other contaminated PPE

Support Zone

The northern support zone contained temporary administrative facilities where Charter

handled communications emergency response and coordination of daily field operations

Communications equipment included hand held cell phones and site ldquowalkie talkiesrdquo The

sanitary facilities safety equipment medical supplies and construction equipmentmaterials

were stored in this area The support zone between Mine Ops and the Tailings Impoundment

contained sanitary facilities and imported sand stone and mulch for incorporation into the

All site visitors were required to sign in and be briefed on the Health amp Safety precautions to be

taken while on site At a minimum each visitor was issued a hard hat and high visibility vest to

be worn while visiting the site

Contamination Reduction Zone

A contamination reduction zone was established as a safety buffer to limit access to the

exclusion zone The contamination reduction zone was placed adjacent to the exclusion zone

perimeter and provided a physical separation of the support zone and exclusion zone

The contamination reduction zone provided an entry for personnel vehicles and equipment into

the exclusion zone and an exit area for decontamination of personnel materials and equipment

from the exclusion zone The contamination reduction zone was identified with paint lines and

lined with poly sheeting to physically separate the zones and to allow for adjustments to the size

and location due to changing site conditions A boot wash plastic garbage bags for used

Personal Protective Equipment (PPE) extra PPE dedicated rubber boot container and

decontamination supplies were placed in this area for use while entering and exiting the

exclusion zone Used PPE was placed in garbage bags and stored in the greater than 50ppm PCB

stockpile area for disposal with the soil

Exclusion Zone

The exclusion zone or hot zone was the area containing PCB contaminated soils in the Former

Mine Operations area as well as the 1‐10 ppm PCB soil stockpile area at the Tailings

Impoundment Since work activities were conducted at different locations within Former Mine

Operations area each excavation area had its own delineated exclusion zone The exclusion

zone included all areas that have been identified having PCB contamination During the

excavation of the PCB soils the exclusion zone was marked by caution tape paint flagging or

other temporary barriers Access and egress from the exclusion zone was through the

contamination reduction zone Personnel and equipment leaving the exclusion zone underwent

decontamination procedures

Heavy Equipment Decontamination

To prevent transport of contamination construction equipment and vehicles were

decontaminated at temporary decontamination areas within the contamination reduction zone

immediately after exiting the exclusion zone Decontamination procedures included dry

decontamination to remove the bulk of impacted soils followed by a double washrinse method

as described in the work plan Wash water produced during these decontamination procedures

was captured and pumped into steel drums Drummed decontamination water was then

processed through the onsite water treatment system

Decontamination water produced from the cleaning on the onsite frac tank at completion of

remediation activities was disposed of by being added to the final load of greater than 50 ppm

soils shipped off site during this phase Water was added immediately prior to load out

Following load out the excavator bucket was decontaminated over the final load of greater than

50 ppm PCB soil being shipped off site

6 Excavation of PCB Impacted Soils

After mobilizing to the site and performing site prep and the installation of EampS controls Charter

started work associated with the PCB contaminated soils located at the Former Mine Operations

area The contamination areas as delineated on the plans were divided up into areas of PCB

concentrations of greater than 50 ppm 10 ndash 50 ppm and 1‐10 ppm Excavation started within

Zone 3 with Zone 4 excavation started shortly thereafter Excavation activities were prioritized

by contamination level as well as soil treatment requirements

61 Soil Treatment

Prior to the start of excavation and loading of the PCB impacted soils accessible 10‐50 ppm PCB

and greater than 50 ppm PCB areas in Zones 3 and 4 that were identified during the ME DEPCES

sampling activities as having a leachable characteristic for lead were treated on‐site This

activity was performed prior to excavation activities due to the lead time associated with lab

testing for TCLP lead and mobilizing the treatment chemical to the site

Treatment was performed using a 1 mix ratio per weight of buffered phosphate treatment

chemical to soil quantity being treated Treatment was done by excavating the soils to be

treated into a pile at an accessible edge of the contamination area Soils were then treated in

situ with the appropriate amount of treatment chemical followed by the soil being flipped and

turned onto itself with an excavator bucket until the soil was thoroughly mixed Sampling of the

soils following treatment was performed by CES and submitted for analytical testing

62 Excavation

Initial onsite delineation for Zones 3 amp 4 was performed by CES prior to Charterrsquos mobilization to

the site Delineation consisted of numbered stakes consistent with the point locations shown

on the plans Differing contamination levels were delineated using flagging and caution tape

When working within contaminated areas Charter equipment was allowed to track from levels

of lower contamination to levels of higher contamination When tracking from levels of higher

contamination to lower levels decontamination of equipment was performed to prevent

tracking of soils Where feasible geotextile or poly sheeting was utilized to ldquobridgerdquo equipment

over certain contamination areas This was done to minimize required equipment

decontamination and to expedite the performance of the work

Following the layout of the contaminated areas excavation activities started on May 14 2013

Initial excavations were performed to a depth of 6rdquo or 12rdquo from the existing ground surface

depending on contamination levels and localized sampling results Deeper excavations were

performed as progression of the work and sequencing allowed Working stockpiles as

referenced in the previously approved Work Plan Addendum were utilized to expedite

completion of the work Grade control of excavation areas was done utilizing an optical level

and a stadia rod Grade control for excavation depths was maintained throughout the course of

remediation activities

EPA Mobile Lab

Confirmation samples for the PCB excavation areas were taken by CES and the Maine DEP

These samples were then submitted to the EPA mobile lab for analysis Soil samples that

required TCLP testing for leachable lead were sent to an offsite lab During weeks when the EPA

mobile lab was not onsite samples were taken to an offsite lab

Zone 3 amp 4 Excavation

Following the completion of site preparation and installation of EampS controls excavation of

Zones 3 amp 4 began at the Former Mine Operations area Excavation was performed in

conjunction with soil treatment in an effort to expedite offsite shipment of soils Zones 3 amp 4

were remediated concurrently as equipment and manpower availability allowed

Zone 3 Remediation

Extensive re‐excavations were required in Zone 3 Most of these re‐excavations were within or

centered around areas 3‐A‐2‐2 and 3‐B‐2‐2 Excavation depths ranged from 6rdquo to 2rsquo depending

on PCB concentrations encountered Large quantities of gt50ppm PCB soils were excavated

from both of these areas Multiple areas had to be re‐excavated 3‐4 times or more CES has a

full record of sample locations re‐excavation areas and levels of contamination Charter

performed the re‐excavations as directed by CES until all confirmation samples produced clean

results

During re‐excavations ledge was encountered in areas 3‐A‐2‐2 and 3‐A‐1 Multiple approaches

were utilized to clean the ledge and weathered bedrock to extent required by MEDEP and EPA

These approaches included sweeping power brooming power washing and vactoring As a

result of discussions had with the MEDEP and CES itrsquos was determined that using a vactor

assisted with a crew of laborers was in the best interest of the project for cleaning

contaminated soil from the exposed ledge Clean Harbors of Hampden Maine provide the

Vactor truck and labor crew for this activity

Following completion of the remediation of Zone 3 the area was rough graded for positive

drainage and to facilitate the placement of Stink Cove sediment Fill material was mined from

the Ore Pad as well as Zone 2 and used to fill in deeper excavations as needed

Zone 4 Remediation

Extensive re‐excavations were also required in Zone 4 Most of these re‐excavations were

within or centered around areas 4‐B‐2 and 4‐B‐1‐2 Excavation depths ranged from 6rdquo to 3rsquo

depending on PCB concentrations encountered Large quantities of gt50ppm PCB soils were

excavated from both of these areas Multiple areas had to be re‐excavated 3‐4 times or more

CES has a full record of failed sample locations re‐excavation areas and levels of contamination

Charter performed the re‐excavations as directed by CES until all confirmation samples

produced clean results

During re‐excavations weathered bedrock was encountered in area 4‐B‐2 Multiple approaches

assisted with a crew of laborers was in the best interest of the project for cleaning contaminated

soil from the exposed ledge Clean Harbors of Hampden Maine provide the Vactor truck and

labor crew for this activity

During re‐excavations concrete was also encountered in various locations within Zone 4

Sampling was utilized to determine if the concrete was contaminated with PCBrsquos as well as

whether or not the contaminated concrete would be relocated onsite or disposed of offsite

Concrete was cleaned andor power washed as necessary prior to sampling Once

contamination levels of the concrete was determined the concrete was broken up with an

excavator mounted hydraulic hammer and segregated for proper disposalrelocation This

approach was also utilized for the demolition of clean and contaminated concrete associated

with the Secondary Crusher building located within the former area 2‐A‐4

63 1‐10 ppm PCB Stockpile at the Tailings Impoundment

While the excavation and offsite disposal activities were being performed in the Former Mine

Ops construction of the 1‐10 ppm PCB stockpile area at the Tailings Impoundment was ongoing

The 1‐10 ppm PCB stockpile area was located within the foot print of the Ore stockpile

previously placed during the 2011 and 2012 phases of work This new 1‐10 ppm PCB soil was

also partially located on previously stockpiled 1‐10ppm PCB soils (placed during 2012 work) and

native soils Initial layout of the limits of the stockpile area was performed by the MEDEP and

CES Following layout Charter began excavating the area for the placement of the 1‐10 ppm

PCB material

The area for the stockpile was split into two adjacent cells The first cell was constructed at the

northern end of the Ore stockpile with second constructed to the south once space constraints

prevented effective placement of additional soils within the northern cell Ore cover material

excavated from the cells was cast upslope and formed into a berm while awaiting completion of

the placement of the 1‐10 ppm PCB material Ore cover material was excavated to the top

elevation of 1‐10 ppm PCB soils placed during the 2012 phase of work In areas where native

soils existed within the proposed stockpile area any topsoil was stripped and the existing

subsoil was used as a base for the stockpile

Following excavation the cells were lined with a demarcation layer of 12oz geotextile fabric

The fabric panels were overlapped on all seams to prevent potential gaps in the fabric Once

fabric was in place filling of the cell began

The stockpile area was filled from north to south The stockpile area was also filled vertically in

layers to accommodate any modifications in the final stockpile design elevations and cover

system

Following the final grading of the 1‐10 ppm PCB material the cap was installed by re‐grading the

previously relocated berm of Ore material back over the 1‐10 ppm PCB material Due to the

insufficient quantity of accessible Ore material at the Tailings Impoundment borrow material

was also mined from Waste Rock Pile 2 and gravel areas in the previously remediated Zone 2 to

compensate for this deficit The cover material was graded in an 18rdquo depth over the 1‐10 ppm

PCB stockpile area On the western edge the cover material was blended into the existing

grades of the drainage swale installed under this phase of work On the eastern and northern

edges the cap was blended to meet the existing grades of the undisturbed Ore

7 Transportation and Disposal of PCB Impacted Soils

In conjunction with ongoing excavation activities soils were also loaded into dump trailers for

transportation and disposal to offsite facilities

Characterization of soils to be shipped off site was performed by CES The excavated materials

were shipped off site under the following disposal characterizations

Greater than 50ppm PCB material (Model City Landfill NY)

Profile NY302494 ‐ Soil Passing TCLP Pb

Profile NY303916 ‐ Soil Initially Failing TCLP Pb and then treated on‐site to eliminate the

leaching hazardous characteristic

Soils being disposed of at Model City were transported by Goulet Trucking Inc Their contact

information can be found in Table 2

Less than 50ppm PCB material (Crossroads Landfill Norridgewock ME)

Profile 522435ME ‐ Soil Passing TCLP Pb

Soils being disposed of at the Crossroads Landfill were transported by TRT Management

Their contact information can be found in Table 2

The trucking manifests for greater than 50 ppm PCB material are located in Appendix A

The trucking manifests for less than 50 ppm PCB material are located in Appendix B

Truck Route

For this phase of the project trucks were routed down Route 15 from Bucksport to Blue Hill

Maine From here the trucks took Route 176 around the western side of the island followed by

a right onto Cape Rosier Road leading to the site entrance This route was chosen to avoid a

narrow hill located in Buckrsquos Harbor and to minimize impact on local residents Any trucks using

Varnumville Road were turned away from the project

Loadout Procedures

Trucking of PCB impacted soils started on May 15 2013 Trucks were backed onto poly sheeting

and loaded by an excavator Trucks were only allowed to travel over clean surfaces and were

not allowed to travel over any contaminated areas

For trucks using removable bows for support of their trailer tarps bows were removed or swung

to the side of the trailer by the truck driver prior to loading Following the trailer being loaded

with soil bows were secured by a Charter laborer from a ladder against the outside of the

trailer This procedure was implemented to eliminate the safety and cross contamination

hazards associated with the truck driver or on site personnel entering a trailer loaded with PCB

contaminated soils

Disposal manifest and weight tickets can be found in Appendix K

8 Site Restoration amp Demobilization

81 Drainage Improvements and EampS Controls at the Former Mine Ops

Drainage Swale

Upon completion of PCB contaminated material excavation and associated work at the Former

Mine Operations area limited restoration activities were started at Zone 3amp4 This included

lining of the drainage swale on the eastern edge of the Former Mine Ops installed during the

2012 phase of work The swale was lined with HDPE liner material provided to Charter by the

MEDEP Liner material was procured by MEDEP from another project site The liner material

was cut to appropriate sizes to fit the swale and shingled to minimize the backflow of water

under the liner sections

Wet Pond and Outlet Structures

Following the lining of the drainage swale a wet pond was constructed at the northeastern

corner of Zone 3 in the area of the former 3‐A‐5 10‐50 ppm PCB soil excavation Preliminary

work for the installation of the wet pond included the grading and shaping of the former

excavations and re‐excavations in the area to form the subgrade for the wet pond This

subgrade was achieved utilizing existing material in the area as well material mined from Waste

Rock Pile 2 and areas in Zone 2

During the shaping and grading work a HDPE standpipe and outlet structure was installed to

drain water from the wet pond Excavation of the linerrsquos anchor trench was also performed A

level spreader and plunge pool were also installed at the outfall of the outlet structure Ledge

encountered during the install of these items was removed to the extent necessary using an

excavator mounted hydraulic hammer

Following the completion of these preparation tasks Charterrsquos liner subcontractor was

mobilized to the site to install a 40 mil textured HDPE liner over the foot print of the wet pond

as well as the forebay of the wet pond The subcontractor utilized for the installation of the

liner system was RTD Enterprises a Maine based company Their contact information can be

found in Table 2

Stink Cove Sediment

The Stink Cove sediment was mined from an onsite area to the southeast of and up slope from

the former Mine Ops Following the clearing of trees and construction of a temporary road for

access to this material excavation of Stink Cove sediment was performed using an excavator

and the material was loaded into rock trucks for relocation to the Former Mine Ops Charter

also added an additional rock truck and bull dozer to the onsite crew as requested by the

MEDEP to expedite the process of relocating and placing Stink Cove material

Once the drainage improvements described above were completed and subgrade was

established Stink Cove material was spread throughout Zones 3amp4 as a loam substitute to

promote grass growth The Stink Cove sediment was placed in an approximate 6rdquo lift over Zones

3amp4 as allowed by the subgrade material

Site Road Improvements

In conjunction with placement of Stink Cove sediment improvements were also made to the

site access road through Zones 3amp4 This included the re‐grading of the existing subgrade and

placement of a 12rdquo lift of processed gravel over the area of the site access road from the

southernmost extent of Zone 4 to where Zones 34 meet Zone 2

Hydroseeding and Stabilization

To stabilize areas disturbed within the Former Mine Ops during remediation activities

hydroseed was applied to the Stink Cove Sediment placed in Zone 3 (35200 sf) Zone 4 (31500

sf) as well as Waste Rock Pile 2 (33075 sf) Erosion control blanket was also used as required

82 1‐10 ppm PCB Soils Stockpile at the Tailings Impoundment

Stink Cove Sediment

Following the completion of the non‐woven geotextile and soil cap for the 1‐10 ppm PCB

impacted soils stockpiled at the Tailings Impoundment the capped area was covered with a 6rdquo

lift of Stink Cove Sediment 31 slopes that received the stink cove sediment material were also

hydroseeded prior to Charter demobilization from the site to stabilize the area

Bought materials and other project associated items were also relocated to the Battery Building

at the request of the DEP so that these materials will be centrally located and can be inventoried

for any follow on work at site Any remaining gravel or stone stockpiles remaining on site were

left in place

To stabilize disturbed areas on and around the 1‐10 ppm stockpile hydroseed was applied to

the Stink Cove Sediment placed over the stockpile cap material The stockpile of rocks from the

Former Mine Ops was also covered with soil and hydroseeded Erosion control blanket was also

used as required
