AMENDMENT 1

(August 1995)

to the

Sediment/Soil Investigation Studies

Mississippi River Pool 15

Phase m Field Sampling Plan

of July 1995

This document provides additional information in support of the Sediment/Soil Investigation

Studies, Mississippi River Pool 15, Phase III Field Sampling Plan dated July 1995.

Modifications are also presented for water sampling. Following approval by EPA, this

amendment will be incorporated into and be adhered to as part of the Phase in Field Sampling

Plan.

1.) COLLECTION OF VOCs IN SEDIMENTS

VOCs in the Phase HI FSP are currently proposed only for the water column. Pursuant to EPA’s

request, VOCs will also be collected in river sediment samples:

• immediately downstream from Outfall 006;

• adjacent to the waste oil lagoon; and

• adjacent to Wetland # 1.

Sediment samples will be collected at both the surface (0-0.5 ft) and subsurface (0.5 ft+) intervals.

We have selected transects defined in the Phase IQ FSP consistent with the above locations at:

1

• Mississippi River Mile (MRM) 489.65 at 10 ft from shore;

• MRM 488.8 at 12.5 ft from shore (upstream from Outfall 003); and

• MRM 489.18 at 10 ft from shore (downstream from Outfall 005).

Sediment samples for VOCs will not be composited, but will be transferred directly from the

sediment sampling device to the respective sampling container. Sampling containers will consist of

4-oz glass containers with teflon-lined caps. For QA/QC, a single field duplicate sample and a

single equipment blank will be collected.

2.) SPLIT SAMPLES

EPA wishes to collect split samples from about 10 percent of the sampling locations within Area 1

to be analyzed for inorganics, PCBs and SVOCs. EPA will provide a list of potential sampling

locations to Alcoa for logistical purposes. EPA will provide all sampling containers, coolers, etc.,

for the split samples.

3. ) METHOD DETECTION LIMIT STUDIES

The current Phase in FSP indicates that method detection limit analyses will be conducted for

carbazole, butylbenzylphthalate and dibenzofiiran. Based on discussions with the laboratory

(Quanterra), method detection limit (MDL) studies are being conducted in accordance with 40

CFR Part 136 Appendix B. Results of the MDL studies will be documented and available from the

laboratory upon request.

4. ) MUSSEL SURVEY

The rationale for limiting the mussel evaluation to Areas 1A, IB and 1C in the current Phase HI

FSP is to focus examination in areas adjacent to the facility with the greatest potential for

contamination. Such areas are also located upstream from Duck Creek, which could potentially

confound interpretation of the mussel data.

2

Also, to clarify US Fish & Wildlife Service (USFWS) concerns regarding mussel tissue collection,

mussels of similar size will be used for analysis both within and between sampling locations (as

opposed to mussels of varying size ranges, which could make data interpretation difficult). Global

Positioning System (GPS) readings will be taken at each location where quantitative mussel

quadrats are collected (as well as where sediment and water samples are collected). The accuracy

of the GPS equipment selected for the study is about 3 meters (~10 ft).

5. ) SCHEDULE AND COMMUNICATIONS

The current schedule is to mobilize for field activities on Monday, September 18, 1995 and begin

sampling on Tuesday, September 19. The general plan will be to collect samples moving from the

furthest point downstream, and moving in an upstream direction. Water samples will be collected

first, followed by sediment samples. Mussel sampling is scheduled to begin on October 2.

Facsimile messages updating field activities will be submitted by the Field Officer (Todd Hunt) to

the Alcoa Project Manager and to EPA on a daily basis.

6. ) NOTIFICATIONS TO OTHER AGENCIES

• Ed Cokel;. IDNR Game Warden 319/349-8927

• Larry Moore, IDNR Game Warden 319/349-9418

7.) WATER SAMPLING STRATEGY

The Phase in FSP currently indicates that water samples will be collected at:

• the downstream boundary of Reference Area 1 (one transect);

• the upstream boundary of CSA 1 (one transect);

• immediately downstream (about 10 ft downstream and 10 ft from shore) from the

mouth of each outfall in which there is flow to MRP 15;

• the downstream boundary of CSA 1 (one transect);

• the downstream boundary of CSA 2 (one transect); and

• the downstream boundary of CSA 3 (one transect).

This approach will be amended to increase the number of reference area samples to seven. Water

samples will be collected at the randomly located sediment sample locations discussed in Section

3.1.6 of the Phase HI FSP.

In addition, instead of collecting two samples at the downstream boundary of CSA 1, three

samples will be collected at the three most downstream transects in CSA 1. At each of these

transects, water samples will be collected at the randomly located sediment sample locations

discussed in Section 3.1.2 of the Phase HI FSP.

4

Lastly, with respect to water sampling locations, instead of collecting two samples systematically at

the downstream portion of CSA 2 and CSA 3, two locations will be sampled from among those

already defined for sediment sampling. Two locations in each area were randomly selected from

the sediment sampling transects as follows:

Area 2 - MRM 486.62 and MRM 486.59

Area 3 - MRM 485.74 and MRM 485.52

With respect to water sampling technique, the Phase EH FSP currently indicates depth-integrated

water samples will be collected using a BOD-type water sampling device. The BOD-type sampler

places limitations on the volume of water that can be collected efficiently (the sampler only holds

about 300 mL). In light of the large sample volumes that are necessary, a large-volume beta-bottle

sampler (acrylic Beta Plus™ Bottle) designed for collection of trace metals and organics samples

will be used. To collect samples that are representative of the water column, subsamples collected

at bottom, mid-depth and surface will be composited in a decontaminated glass container. The

samples will be distributed to the respective sample jars from the glass container. The exception

will be for volatile organics samples, which will be collected from mid-depth and delivered directly

from the sampler to the respective sample jar. A revised Standard Operating Procedure for water

sampling is attached.

8.) HEALTH AND SAFETY PLAN - DIVING SAFE PRACTICES PLAN

The 1991 Sediment/Soil Investigation Studies Work Plan for the soil/sediment investigation studies

does not contain a section regarding Safe Diving Practices. Since diving will be a component of

the Phase HI Studies, a copy of the project Diving Safe Practices Plan is attached with this

amendment to the Phase HI FSP. It is anticipated that a subcontractor will be used to assist in

collecting mussels in the river. Conformance to 29 CFR Part 1910 is a requirement of the Health

and Safety Plan. However, we request that this requirement be waived for the subcontractor: the

subcontractor will only be allowed to collect biological specimens (i.e., mussels); the subcontractor

will not be allowed on site; and the subcontractor will work only under the supervision of an

individual with 40-hr OSHA training.

• Deionized or distilled water

• Decontamination buckets/pails

• Several spray or squirt bottles

7

3.2 SAMPLING PROCEDURES

This section gives the step-by-step procedures for collecting water samples. Observations made

during sample collection shall be recorded in the field notebook.

3.2.1 Decontamination of Equipment

Before any sampling begins, and between samples, the sampler shall be decontaminated according

to the FSP. Decontamination supplies will be provided so that equipment can be decontaminated

in the field.

3.2.2 Obtaining Water Samples

The following procedures are to be used to collect water column samples.

1. Assemble all sampling equipment and place on board the sampling vessel. Proceed to the

sampling location.

2. When on location, prepare the water sampler. Decontaminate if not already completed.

3. Open and lock the ends of the sampler.

4. Lower the sampler into the water until it reaches the desired depth.

5. Release the messenger so that the ends of the sampler are closed.

6. Retrieve the sampler and distribute the sample to a compositing container or to individual

sample jars, as necessary. Samples collected for volatile organic analysis shall be delivered

directly to the sample container. Volatile organic samples shall be delivered very slowly to

the sample container to minimize turbulence and potential loss of volatiles to the

atmosphere. There must be no bubbles in the sample container after it is capped.

6. Retrieve additional samples if required to attain sufficient sample volume.

8

7. When sufficient sample volume has been collected, decontaminate the sampler and wrap in

clean plastic or aluminum foil or place in closed case before moving to the next sampling

location.

DIVING SATE PRACTICES PLAN

1.0 INTRODUCTION

This plan sets forth the rules Woodward-Clyde divers will follow when using SCUBA or surface-

supplied air to work underwater. The rules and practices in this manual will be followed, unless the

onsite conditions dictate a change to be made by the divemaster. All changes will be approved by

the site Health and Safety Officer and the Alcoa Project Manager, and will follow standard diving

safety rules

2.0 SCOPE OF WORK

Diving during this project will be used to collect mussels in Mississippi River Pool 15 (MRP 15).

The data will be used to assess species presence and composition. Limited mussel tissue samples

will also be collected. Mussels will be collected in the vicinity of Mississippi River Mile (MRM)

487 to 489. In addition, mussels will be collected from a control area upstream at about MRM

490 to 491. Specifics of the mussel sampling effort are detailed in Sediment/Soil Investigation

Studies, Mississippi River Pool 15, Phase III Field Sampling Plan (WCC 1995).

In addition, diving may be used to assist in collecting sediment core samples in MRP 15.

Sediments may be collected in several areas within MRP 15, also as outlined in Phase III Field

Sampling Plan.

Diving will generally be conducted from a boat, but sediment and/or mussels samples may also be

collected from shore in near-shore areas. The diving strategy consists of one or two divers in the

water collecting mussels or sediments, and a third diver aboard the boat as tender and boat

operator, ready to enter the water should the need arise.

10

3.0 TRAINING

All members of the WCC dive team will be certified by one or more of the industry recognized

certification agencies (e.g., PADI or NAUI). The designated divemaster for this project will be

Mr. Don Spires. Experience in diving under special conditions, using specialized equipment and

diving in general can be used as supplements or in place of advanced courses if approved by the

divemaster. Only divers that are experienced, comfortable with the dive conditions and meet the

physical requirements for the job will be allowed to conduct work.

4.0 HEALTH AND SAFETY

4.1 Dive Plan

A dive plan is to filled out for each project and approved by the Dive Master and Health and Safety

Officer. The dive plan for this project is attached.

4.2 Safety Meetings

Prior to diving, the entire dive team will be briefed in detail on all aspects of the work to be done.

This is to include: description of the project, location, type of diving equipment and craft to be

used, maximum working depths with estimated bottom times and water temperatures, names and

duties of all personnel on the team, discussion of active hazard analysis and emergency procedures.

At the start of each day a Health and Safety meeting will be held at the scene of the dive with all

members of the dive team. In addition, before each change in dive plan, strategies or conditions, a

supplemental Health and Safety Meeting will be held.

4.3 Medical

All WCC personnel conducting diving operations will pass a medical examination performed by a

licensed physician (preferably qualified in barotrauma and hyperbaric medicine) prior to initial dive

operations. This medical examination will be repeated, at a minimum, every twelve months. Each

11

diver will be reexamined after any injury requiring medical attention or illness requiring

hospitalization.

Copies of the medical exam, signed by the attending physician, will be submitted to the divemaster,

to the client, and to the project Health and Safety OflBcer.

4.4 Air Travel

No diver will fly within 12 hours of completing any dive. Should multiple days of repetitive diving

be the case then an interval of 24 hours will be required.

4.5 CPR and First Aid

All WCC dive team members and support staff will have current certification in cardiopulmonary

resuscitation (CPR) and Red Cross First Aid or equivalent.

4.6 Decontamination

Use of a dry suit or semi-dry suit is preferable over a wet suit. Following completion of diving, the

diver(s) are to wash in the field using a portable shower while removing equipment, then proceed

directly to the hotel and shower. Following each day of diving, the suit is to be detergent washed,

rinsed in tap water, and air dried.

5.0 EQUIPMENT

5.1 Surface Supplied Air

Surface-supplied air will be utilized whenever possible instead of SCUBA Conditions that favor

surface supplied air include a single location work area and large areas of shallow water where

maneuverability is not a problem. In areas where there is a risk of air line entanglement,

accessibility is a problem, where other site-specific problems may interfere with surface-supplied

air, or surface-supplied air is unavailable, then SCUBA will be used. Surface-supplied air units will

be inspected before each dive by the divemaster and will be monitored by personnel versed in the

operation of the unit.

12

5.2 SCUBA

All equipment will be inspected by the divemaster before each days work. Each member of the

team will also inspect their own gear before each dive. Any suspect equipment will be replaced

using backup equipment and repaired before being used on a dive. All equipment will have regular

maintenance. Regulators will be serviced by an authorized service center on a yearly basis.

Buoyancy compensators (BC) will be serviced as needed, with worn fittings replaced. If the fabric

becomes worn to the point that failure is possible, then it will be discarded and replaced.

Each diver will have a minimum of the following equipment for scuba operations:

• A regulator with an octopus, tank pressure gauge, and a depth gauge.

• A buoyancy compensation (BC) device capable of regulating the buoyancy of the

diver while working and maintaining the diver at the surface in a face-up position.

• Weight belt with a quick release.

• Dive knife on every dive, plus a wire cutting tool should fencing or wire be a

hazard.

• Timing device for recording individual dive times.

All air tanks used in dive operations will be of seamless steel or aluminum construction which meet

U.S. Department of Transportation (DOT) 3AA, DOT SP6498 and DOT E6498 specifications.

All tanks will have the manufacturer's identification symbols stamped in the shoulder of the tank.

Each tank will undergo visual internal inspection (VIP) annually and will be hydrostatically tested

at least once in 5 years in accordance with DOT and the Compressed Gas Association regulations.

VIP labels are to be placed on the side of the tank, while the hydrostatic test dates are to be

stamped in the shoulder.

13

Should conditions exist (visibility less than 3 feet, current greater than 1 knot) that dictate a diver

be tethered, a safety harness will be used, equipped with a positive buckling device. The attachment

point of the safety line will be such that the lifting point distributes the pull force of the line over the

diver's body.

14

2. Location of Project: Mississippi River Pool 15 near. Davenport. Iowa

Dates of Project: Tentative period between September 18 to October 31. 1995

Times: daylight hours

3. State dive mode (e.g. SCUBA, Surface-supplied air) to be utilized and justification for

mode.

Surface-supplied air will be the primary mode, and will be supplied by the subcontractor for

the project. SCUBA will be used by the safety divers. Due to the large area necessary to

be traversed, SCUBA may also be used as a primary mode of diving

4. State the nature of the word to be performed and any special requirements for equipment,

supplies or training.

Mussel and sediment collection. Visibility is expected to be low with current speeds

potentially exceeding 1 knot. If SCUBA is used, then a tether may be required.

5. State the expected surface and underwater conditions, (current, visibility, temperature,

etc.).

Surface conditions are expected to be clear and cool, with temperatures characteristic of

the fall period. Surface water velocities may be as high as 2 knots, with bottom velocities

(where mussel and sediment collection will be performed) generally less than 1 knot.

Visibility is expected to be minimal, to no visibility.

6. List any potential hazards for any member of the team for each phase of work expected.

Potential hazards consist of local boat and barge traffic, potentially high water velocities,

and debris being carried in the river.

7. State the maximum possible depth that could be encountered, the maximum bottom time

and the surface interval needed before a second dive.

2

The maximum possible depth that is expected is less than 18 ft. Maximum bottom time

will not exceed 45 minutes per dive, or 6 hrs for any individual per day. Diving will not

exceed 15 feet in depth unless authorized by the divemaster. Due to the relatively shallow

depths, there is no explicit surface interval needed before a second dive.

8. List any deviation from the emergency management plan that is needed to comply with the

special conditions of this project.

None

9. List any and all equipment that needs to have lock out/tag out procedures, how this will be

accomplished and who will be in charge of the procedure while divers are in the water.

None

10. List the VIC and Hydro dates on all tanks used, dates of last regulator servicing and attach

all service records on special equipment used on this project.

(To be provided at dive site)

A dive log (form attached) is to be filled out after every dive.

If for any reason the dive plan is altered in mission, depth, personnel, or equipment, the ALCOA

Project Manager and the site Health and Safety Officer shall be contacted in order that he may

review any revision prior to actual operation.

This plan shall be submitted and accepted by the ALCOA Project Manager and the site Health and

Safety Officer prior to commencement of diving operations.

A copy of the plan shall be at the diving location whenever diving is conducted.

3

The plan shall be made available to the government representative: all dive plans will become part

of the contract file.
