1980 concerning Metal Bank ofDear Dr. Bhatla: America, Inc.

The groundwater from the Metal Bank property as described in thesubject letters are unacceptable for discharge into the Philadelphia SewerSystem.

Assuming that the majority of the 8 Ibs. of PCB's would be discharged^venly over a 100 day period, during that period the increased concentration

the NEWPC Plant sludge could be expected to be about 0.8 ppm (dry wgt.basis); that is, assuming essentially 100 percent removal. Since the currentPCB concentration of the NE sludge is about 0.7 ppm the Metal Bank contributionwould approximately double the concentration. In addition, there is the possi-bility of higher peak values.

As you are aware the City is embarked upon an intensive program to phaseout ocean disposal of its sludge. Increasing concern about "trace organics"including PCB's and the fact that the proposed Metal Bank discharge is a"controllable" not "background" source the acceptance of it could be ex-tremely damaging. That is, particularly for public relations but also forregulatory agency considerations. It could also weaken any regulatory actionstaken by the City against dischargers into the sewer system that affected sludgequality.

Regarding the cost, the current sewer charges (above minimum) are $2.27 per1000 cu. ft. At 50 gpm this would be approximately $8,000 per year. Also, ameter would have to be provided to record the flow.

Captain J. R. KirklandCaptain of the PortPhiladelphiaU. S. Coast Guard BaseGloucester City, NJ 08030 Proposal No. 1463

Dear Captain Kirkland:

As a result of our project meeting on 14 August 1979 at Base Gloucester,Roy F. Weston, Inc. (Weston) is pleased to submit this proposal forcontinuation of consulting work performed by us as reported in ourstudy report titled "Hydrogeologic Evaluation of a Subsurface Oil Spillat the Metal Bank of America, Inc. Disposal Site, Philadelphia, Penna."

BACKGROUND<—

In 1978, under contract no. DOT-CG03-7493, Weston had investigated theMetal Banks of America's (MBA) PCB spill site, and had defined thedistribution of PCB's at the site at that time. Our report included anestimation of the quantity of oil containing PCB's, the extent ofmigration of subsurface oil, the concentration of PCB's, the extent ofmigration of subsurface oil, the concentration of PCB's in oil andgroundwater, and the hydrogeological conditions at the site. As aresult of the study, Weston estimated the potential release of PCB'sfrom the Metal Banks' property. In addition, Weston's report of thestudy described several conceptual control measures for mitigating therelease of PCB's from the site.

PURPOSE AND SCOPE OF PROPOSED STUDY

The purpose of the proposed study is to prepare concept designs andcosts for the various alternatives which will be used for controllingPCB releases from the site. Data thus developed will provide variouslevels of PCB control for different levels of expenditure.

The effort under the proposed work scope w i l l be directed only to theprimary PCB-iaden oil spill located at the South end of the property.Subsurface oil detected towards the North end of the property will notbe considered in these control measures.

Weston realizes, the potential problem from presence of PCB in bottomdeposits in Delaware River along MBA property line; however, as directedby you in the 14 August meeting, this problem w i l l not be addressed inthis proposed project. As mutually agreed, due to the site constraints,

Weston w i l l utilize already available state-of-the-art treatabflityvdata and will minimize field and laboratory development work forcompleting this proposed project.

The scope of the study will consist of evaluation and, as necessary,preparation of concept designs and estimated costs for variousalternatives, including:

1. Subsurface oil removal and disposal.

2. Contaminated subsurface water removal, treatment,and disposal.

3. Reduction of water inflow to the site, considering. both on-site and off-site water diversion.

k. Other applicable site management methods.

5. Site monitoring needs and costs.

For a better mutual understanding, a detailed description of thevarious project ta.sks is presented in the following paragraphs.

PCB SOURCE REMOVAL

The previous study established that there were approximately 21,000gallons of oil pooled below the site, containing approximately 215pounds of PCB's. This entrapped subsurface oil was the major sourceof PCB release via oil and water leaching.

Based on this previously developed knowledge, the following steps willgenerally be included under this alternative:

1. Subsurface water level and oil thickness updating.

,1.. . Location(s) and number of oil recovery points.

3. Type of oil pumping system.

4. Size of well, pumping rate, and quantity and qualityof material pumped.

5. Up to two activated carbon adsorption isotherms for PCB's,COD and BOD to confirm order-of-magnitude kinetics for thevarious parameters and to predict treated water quality.

6. Field STS test(s), oil gravity, and qualitative laboratorytests for oil-water emulsion breaking, as necessary.

9RI00122-2-

7. Definition of oil/water separation system, and water -treatment process. Conceptual flow diagrams w i l l bedeveloped.

8. Definition of oil and water disposal methods.

9. Capital and operating cost estimation for an oilremoval system.

Testing for priority pollutants in the groundwater at the site isnot contemplated at present because this could be addressed duringthe implementation phase of the project.

INFLOW WATER REDUCTION TO AND THROUGH THE SITE

There are three water inputs to the site, namely:

- 1. Rainwater infiltration.

2. Off-site surface runoff onto the site.

3. Upgradient groundwater flow to site.

Under the inflow reduction alternative, evaluation of the followingwill be included:

1. Selection of the optimum method for making the siteimpermeable from techniques such as surface paving,regrading, and providing a clay liner with vegetation.This will include estimation of storm water quantityand its satisfactory drainage from the site.

v 2. Diversion of off-site runoff plan as necessary.

3. Cost estimate for the selected surface water drainagemethods as applicable.

k. Evaluation of the need and practicality of groundwaterdiversion from the site, and determination of costs,as necessary.

It is understood that Weston.will work with the existing topographicinformation available for the site, and no attempt will be made toresurvey the site.

SITE MANAGEMENT

Site management needs will be defined. These may include items such asidentification of disposal areas, monitoring of surface runoff andgroundwater quality, tentative use of site, and any maintenance require-ments for the site. Weston will estimate costs for necessary sitemanagement to provide effective control of the site and long-termmonitoring.

-3- AR100123

SUMMARY REPORT

Results of all steps will be summarized as a final chapter to ourexisting report. Cost estimates w i l l be presented in a manner so thatdifferent levels of mitigation can be identified with costs. Ten_copies of the summary report will be submitted to the U. S. Coast Guardas a part of this contract.

PROJECT MEETINGS

Two project meetings (four man-days) are allowed within the scope ofthis project. These will be used for reporting project progress andproject results.

CONSULTATION

During the course of the project or following completion of the project,Weston personnel may be required to consult with ERA, state regulatoryagencies, or local authorities. We have allowed four man-days for theseactivities under the scope of this proposal. Additional time, if needed,will be charged at our current hourly rates, plus out-of-pocket expenses^reimbursement.

BUSINESS PROPOSAL

It is proposed that the outlined project be performed on the basis ofhourly charges for personnel, plus direct expenses. It is expected thatthe services outlined herein can be accomplished for the ESTIMATEDPROBABLE COST. Only those costs incurred will be charged. To avoidmisunderstanding, it should be emphasized that the ESTIMATED PROBABLECOST is our best estimate based on the knowledge of scope of work atthis time.

Manpower Cost - $26,650Expenses - 3.250

. ESTIMATED PROBABLE COST - $29,900

Work on this project can be initiated within 15 calendar days ofapproval of our work scope, and completed within 90 days thereafter.

A list of our current hourly rates is attached. Our applicable laboratoryanalytical analysis rates are also attached.

PROJECT PERSONNEL

The following personnel will be assigned to this project to maintaincontinuity with our past activity at the site, and to allow access tothe site to a limited number of staff. Biographical sketches of thes'epersonnel are presented at the end of this proposal.

The success of using retrieval wells depends on the proper constructionof recovery wells. The recovery wells should be properly constructed,gravel-packed and installed with suitable screen to provide maximum openarea. 7/y** —£*•»-»-'»-» -g J •*-

It is proposed to dri 1 l_these wel Is (12 to 20 inches irr diameter) atleast two to th>ee"7feet: into the clay layer to allow sufficient roomto Install the pump." Solid casing should be installed opposite thisclay bed to house the pump. The entire aquifer should be screened withabout one to two feet of screen rising above the normal water table toaccomodate any fluctuation of levels of water and oil. AH wells shouldbe gravel-packed well above the screen level and the backf H led w4th~native^ soil .,„ Th«?..weJJs should be constructed under th'e cjose super- —vl si ongof a qua 1 i f led hy d rogeol 6g i s t with oil rec6veiry~"experierice 'to ~~Insure proper-ijistallation and functioning of these welte*-^ _ -?;;

The recovery wells should be equipped with separate pumps for pumpingwater and oil. A submersible pump of the size needed for each well tocreate the depression in the water table should be Installed at thebottom of the well to pump clean water. The expected pumping rate_of —water varies from 30 to fa gallons per minute. A sump pump should .beinstalled with the intake set about 2. to 3 Inches above the oil/

ftLffr V rwater interface to pump oil. The 9*mp pump should be capable of pumpingone to five gallons per minute. Figure; 6-1 shows the design of a proposedrecovery well with the settings of both oil and water pumps. The cleanwater should be pumped continuously to maintain the cone of depression.The oil should be pumped out periodically as it builds up in the well.The. pumping of water and oil could be automated using float arrangements
