The remedies selected for groundwater and soil include: • MIGRATION CONTROL (Remediation of Contaminated Groundwater). Groundwater extraction will be accomplished with the use of extraction wells located within and near the periphery of the plume. Groundwater cleanup standards are presented in Table 1-1 (EPA 1992a). Extracted groundwater will be treated onsite in an above-ground treatment process that will include the precipitation, flocculation, and filtration to remove metals; and air stripping to remove volatile organic compounds (VOCs). After treatment to meet the National Pollutant Discharge Elimination System (NPDES) permit requirements, the extracted groundwater will be discharged to Chinnis Branch. • SOURCE CONTROL (Remediation of Contaminated Soil). Onsite soil with concentration levels of contaminants above cleanup standards [Table 1-2 (EPA 1992a)] will be excavated and treated. Contaminated soil will be treated onsite by a low temperature thermal desorption unit (LTTD). Each batch will be tested to determine whether concentrations of heavy metals exceed cleanup standards; if so, soil will be treated by stabilization (either in situ or ex situ). To develop a remedial design to address site conditions, the U.S. Environmental Protection Agency (EPA) has requested the support of Bechtel Environmental; Inc. (Bechtel). Bechtel has prepared this remedial design (RD) Work Plan under authorization of EPA Contract No. 68-W9- 0058, Work Assignment No. 22-4NC4. This RD Work Plan addresses the scope, schedule, budget, project staff and underlying assumptions for a performance based remedial design. In addition, Bechtel may provide technical support during proposal solicitation and negotiations with potential remedial action (RA) contractors as requested and funded by EPA. Prior to the RD of the treatment systems described in the ROD, additional soil and groundwater investigations will be undertaken. 2.0 BACKGROUND 2.1 SITE LOCATION AND DESCRIPTION The Potter's Pits Site is in a rural area of Brunswick County in southeastern North Carolina (Figure 2-1), situated in the residential community of Sandy Creek, approximately 17 miles west of Wilmington. The town of Sandy Creek is subdivided into 1-to 2-acre lots. There are approximately 150 residential lots in the vicinity of the site; 70 are presently occupied. An occupied residence is actually on the site. 1.359 1 Contaminant Benzene Toluene Ethy !benzene Xylenes Naphthalene Chromium Lead NOTE: ppb -parts per billion SOURCE: Table 1-1 Groundwater Cleanup Standards Potter's Pits Site Cleanup Standard (ppb)1 5 1,000 29 400 30 50 15 EPA ROD for Potter's Pits Site, August 5, 1992 (Table 8) 1.359 2 Table 1-2 Soil Cleanup Standards Potter's Pits Site Contaminant Cleanup Standard (ppb)1 Benzene 10 Toluene 3400 Ethy !benzene 235 Xylenes 3500 Naphthalene 1800 Carcinogenic PAHs* 11 Chromium 97,200 Lead 25,000 Zinc* 122,000 NOTES: 1 ppb ~ parts per billion * Cleanup standard will be applied to the top foot of soil only SOURCE: EPA ROD for Potter's Pits Site, August 5, 1992 (Table 7) 1.359 3 a / ,/ ,-_;;.-i.-·· -.,# , I ...._.,,....__, ' ' ___, / (·. ~ :- 1 I ' I' ·, '. 1· \ ..

Weston, 1992, RI Addendum) , ... • OCIO n 4 The Potter's Pits Site is at approximately 60 feet (approximately 18 meters) above mean sea level (msl) and adjacent to the Little Green Swamp (Figure 2-1). This swamp forms the headwaters for Chinnis Branch, which traverses the site as it flows towards the northeast. The area surrounding Chinnis Branch is a forest/wetland region. Potter's Pits (Figure 2-2) was divided into three study areas: Areas 1 and 3 are in residential lots within Sandy Creek, and Area 2 is approximately 1.5 miles north across U.S. Highway 74/76. Area 1 comprises the actual Potter's Pits Site. Area 3 was included in the investigation because historical aerial photographs suggested that this area might have been used as a disposal site. Area 2 was removed from further investigation after an extensive search indicated no additional information regarding its specific location (EPA 1992a). 2.2 SITE HISTORY Prior to residential development of the Potter's Pits Site, the Skipper family operated sludge hauling and oil spill cleanup companies in the area. Disposal practices included the placing of waste petroleum products and septic tank sludges in shallow unlined pits or directly on the land surface. The Potter's Pits Site includes an area where these previous disposal practices occurred. In August 1976, an unlined disposal pit was breached and approximately 20,000 gallons of oil was released. The oil entered Chinnis Branch and was transported downstream to Rattlesnake Branch. Operations were undertaken to remove and transport from the site remaining oil, oil-stained dirt, and oil recovered from the receiving stream. Oil sludge that could not be pumped was mixed with sand and buried onsite. In 1980, ownership of the property changed hands, through foreclosure, from the Skipper Estate to Wachovia State Bank. Investment Management Corporation later purchased the property and developed it into the residential community of Sandy Creek. In 1982, site lots were purchased by Earl and Dixie Gurkin and developed as a private residence. In July 1983, the Gurkins found buried waste materials in their yard; the state of North Carolina was notified and subsequently collected soil samples on the property and groundwater samples from the Gurkins' private well. The well, found to be contaminated, was condemned, and its use was discontinued. A remedial investigation/feasibility study (RI/FS) was initiated in January 1990, and the ROD was signed on August 5, 1992. The ROD was prepared to summarize the remedial alternative selection process and to present the selected alternative, in accordance with Section l 13(k)(2)(B)(v) and Section l 17(b) of the Comprehensive Environmental Response Compensation, and Liability Act of 1980 (CERCLA) as amended by the Superfund Amendments and Reauthorization Act (SARA). 3.0 PROJECT OBJECTIVE The objective of this work assignment is to provide technical, contractual, and engineering support services for RD activities at the Potter's Pits Superfund Site in Brunswick County, North Carolina.

An independent evaluation and location rationale is not required. ran.aqUjfer]est:locaiioiuvillJje0propose~; li~igtL.WillrfollciWthat'ofca ~afd:operatmg_procedure·or~the:direction:of-EPA. Bechtel will prepare a Field Operations Plan (FOP) that will be applicable to additional field data acquisition, Section 8.4. The FOP will include a Sampling and Analysis Plan (SAP), a QAPP, and an HSP. The SAP will provide protocols for collecting, storing, packing, and shipping environmental samples. The QAPP will specify procedures, checks, audits, and corrective actions to ensure the reliability of the technical and reporting activities. The HSP will provide appropriate procedures to protect workers, the public, and the environment during field activities. EPA will provide to Bechtel prior plans (FOPs, SAPs, QAPPs, and HSPs) used at Potter's Pits during earlier phases of work (1990 RI Addendum). It is assumed that the plans will be made available to Bechtel and will be directly adopted for the additional field effort. 1.359 11 Following EPA's review of the Draft FOP, Bechtel will revise the document in accordance with EPA's comments and prepare the Final FOP. A response letter will not be supplied. 8.2 SOW TASK I-PROJECT PLANNING SOW Task 1 provides for project planning during the early stages of the project. The work effons associated with this task include those that were not funded under the interim budget. They are listed below, as presented in the SOW (EPA 1992b), and described in the narrative that follows. Review of peninent documents Pre-design coordination meetings Pre-design site visit Initial value engineering screening Treatability review Preparation of preliminary RA schedule • • • • • • • • • • Selection of indicator compounds and appropriate analytical protocols Selection of additional sampling locations Preparation of Draft and Final RD Work Plan Preparation of Draft and Final FOP Review of Pertinent Documents A limited review of peninent documents was performed as part of-Task PP2. However, additional detailed review of these documents will be required during development of the design documents. Pre-design Coordination Meetings This task was implemented under Task PPS. · Pre-design Site Visit This task was implemented under Task PPS. Initial Value Engineering Screening No formal value engineering studies will be undenaken; however, value added considerations will be employed during development of the design through peer and construction reviews after the final RD Work Plan has been approved. Treatability Review This task will be performed as SOW Task 4. 1.359 12 Preparation of Preliminary RA Schedule Bechtel will evaluate the anticipated RA activities and develop a preliminary summary level schedule of implementation, including construction of the various elements and operation/maintenance periods of the groundwater systems. This schedule will be a monthly based schedule. Selection of Indicator Compounds and Appropriate Analytical Protocols Bechtel will review the list of contaminants of concern for the site and select easily detected indicator compounds to be analyzed for during the RA. These indicator compounds and screening protocols will be used by the RA Contractor to direct the RA in a real time basis. At completion of the RA, a final verification sampling round of all the contaminants of concern will be made to ensure that cleanup standards have been achieved during the RA. Bechtel will also make a recommendation concerning the use of a mobile or fixed laboratory to support the RA activities. Selection of Additional Sampling Locations This task was implemented under Task PP9. Preparation of Draft and Final RD Work Plans This task was implemented under Task PP4. Preparation of Draft and Final FOP This task was implemented under Task PP9. 8.3 SOW TASK 2-RELOCATION OF ONSITE RESIDENTS Bechtel will develop a relocation strategy and plan for the onsite residents. This plan will address movement of all personal belongings and buildings to a location within three miles of the current location. The plan will address site preparation, site grading, utility hookup, temporary housing, damage compensation, and modification of current location. A site visit is expected to be required to assess the requirements of the relocation. Bechtel will solicit bids from three subcontractors to perform the relocation of the onsite residence. EPA will identify any limitations to the RD schedule for the relocation and provide a detailed list of those items which need to be relocated. The LOE required to accomplish this task may warrant modification following the site visit. If this is the case, Bechtel will notify EPA and additional efforts as requested and funded by EPA will be performed. Prior to the award of the relocation subcontract, an assessment will be made to determine if a cash settlement would be more cost effective than an EPA subcontract. 1.359 13 8.4 SOW TASK 3-FIELD DATA ACQUISITION/SAMPLE ANALYSIS Additional field data acquisition/sample analysis will be performed by Bechtel and used in the development of the RD. The implementation of this task and use of these data will be after the Final FOP has been approved and the task funded by EPA. Soil samples will be collected in Areas I and 3 to provide better definition of VOCs and metals in soil in this area. Additional soil samples may be taken to aid in treatability studies (if so directed and funded by EPA). Groundwater sampling will address offsite background metals concentrations in the shallow and deep aquifers and verify the possible contamination of the deeper aquifer. This data will serve to address data gaps presented in the ROD and data results of the RI Addendum. Additional wells may be required in both the shallow and deep aquifers if so directed and funded by EPA. To further characterize aquifer parameters and collect necessary data to design a groundwater extraction system, a pump test will be performed. EPA'"wil[pr~ii:le tlfe-pro'cedure::for_~ PJ:2P.Osed pump_test. Any modification or addition to this hydrogeologic characterization will require the approval of EPA and the budgeting of additional hours. 8.5 SOW TASK 4-TREATABILITY REVIEW Bechtel will develop a "position paper" that addresses the issue of treatability of soil by low temperature thermal desorption. This effort will include a literary search, site history, communication with potential vendors, and, if appropriate, industry case studies. Following EPA f review of the "position paper," Bechtel may provide additional tasks as outlined in the SOW , Task 4 (EPA 1992b}, if directed and funded by EPA. 8.6 SOW TASK 5-DATA EVALUATION This task includes efforts related to converting existing data and the newly obtained data generated during the field data acquisition phase (SOW Task 3) into a usable format for design.

Dr. Ganapathi is currently a Project Manager for various environmental pollution control and hazardous waste projects. He is also the Group Supervisor for Environmental Treatment Technology, supervising a staff of 15 engineers. He has had technical and management responsibility as the Lead Project Engineer or overall Technical Manager for a wide range of projects. Some of these are summarized as follows: PROFESSIONAL EXPERIENCE Industrial Environmental Management Experience • Conducted performance evaluation and treatability studies for M&M Mars candy manufacturing plant WWTP in New Jersey and resolved their long-term operational pr'oblems, modified their obsolete treatment methods, commissioned cost-effective anaerobic treatment method. Conducted an intensive training/workshop for WWTP personnel (approximately 30 participants) to acquire state operators' license. As a recycling effort, the methane generated from the WWTP and anaerobic sludge digester is currently being recycled to heat WWT units. The WWTP is currently in full compliance with the state discharge requirements. • Conducted in-plant pilot plant treatability studies for hazardous liquid wastes at Roche, an international pharmaceutical plant in New Jersey. Conducted a two-week operator/laboratory technician training course. The training involved O&M. mock-emergency scenarios. Gomes Ganapathi Page Two including spill occurrence. As a part of the treatability study • .waste minimization through recovery and recycle of organic solvents was evaluated. After the remediation was performed, in spite of an increased production rate. the pharmaceutical plant used less than two third volume of organic solvents and water that was being used in the early '80s. Per Dr. Ganapathi's recommendation, the digester sludge that was being shipped to hazardous landfills for disposal is currently being burnt in a cogeneration plant and thus saving nearly · $0.SM year for the client. The high strength (BOD > 800 ppm) aerobic activated sludge plant is being convened into an anaerobic treatment plant, per his recommendation, that has indicated substantial savings. • Dr. Ganapathi evaluated the performance of a malfur1ctioning WWTP. at a psychiatric center in Harlem Valley, NY, not in compliance with the state discharge regulations. Based on his detailed study. the obsolete equipment were replaced. loading rates were modified. operator/lab technicians were retrained, and startup of the plant was carefully studied. The plant has never violated the discharge requirements since then. • Dr. Ganapathi prepared O&M Manuals including the H&S plans for one brewery WW1'P and three municipal WWTP in upstate New York. These projects involved retraining of plant personnel with specific reference to sampling techniques and pseudo-emergency situations. The emergency training included operator response during illegal dumping in sewers and plant overflow. Two of the studies included independent auditing sponsored through the state. • While at Oklahoma State University, Dr. Ganapathi. in the capacity as a research assistant, conducted pilot plant studies for phenolic wastes and plastic industrial wastewaters; synthetic fuel wastewater treatment (Water Research Center, Oklahoma State University); evaluated the biological treatability of high strength wastewaters aerobically and anaerobically -completely mixed, fixed bed and batch studies: evaluate and monitor performance of Stillwater Municipal WWTP and brought the effluents under control; monitor and control their anaerobic digesters for six months; involved in the design of land application of Stillwater Municipal WWTP sludge. • For the Channel Master Superfund Site remediation project. North Carolina. Dr. Ganapathi conducted site characterization. managed cost and schedule and subcontracts. and coordinated with EPA. The site was contaminated with heavy metals and chlorinated aliphatics due to wastes generated during electroplating operations. Innovative/inexpensive techniques such as a hydropunch were used to track the contaminated groundwater plume. Dr. Ganapathi was instrumental in developing remedial alternatives for contaminated groundwater, soils, and an area of sludge drying beds. With his extensive hands-on experience at hazardous waste sites, Dr. Ganapathi trained field personnel and subcontractors for health and safety and field sampling protocols. A record of decision based on alternatives recommended by Bechtel was taken in September 1992. Gomes Ganapathi Page 3 • As a Project Engineer for vai:ious hazardous waste sites, Dr. Ganapathi was responsible for key technical issues for the following projects: Petroleum Products Superfund Site, Florida -develop planning documents and regulatory requirements. Dr. Ganapathi played a key role in developing the alternative assessments for this site contaminated with petroleum hydrocarbons and lead. Maxey Flats Disposal Superfund Site, Kentucky -Develop Remedial Alternatives, coordinate with potentially responsible parties. Alternatives such as grouting as recommended by Bechtel were approved by EPA. Indiantown Superfund Site -Develop cleanup goals, conduct cleanup verification RI. This site is an abandoned steel mill site contaminated with PCBs and heavy metals. Dr. Ganapathi as the lead engineer developed a statistical sampling strategy and conducted field screening using a cost effective PCB analytical method. Newtown Creek Site, New York -Develop cleanup goals. review regulations, conduct site characterization for the purpose of expanding the existing WWTPs. and evaluate data. For several formerly utilized sites previously operated by the U.S. Department of Energy, Dr. Ganapathi participated in site characterization and remediation activities involving a variety of radioactive soils and hazardous materials. • Dr. Ganapathi's experience with the New York state provides him with additional credentials in managing small size hazardous waste projects. Dr. Ganapathi had to closely manage these low-budget projects (Clifton Park, German Flatts, and Williamson Landfill) that nevertheless required high levels of health and safety protection. As an example of his sensitivity to satisfying client requirements while at the Williamson Landfill site. Dr. Ganapathi stopped the drilling subcontractor, who delayed collection representative groundwater samples due to inclement snow conditions, violating health and safety requirements, and reorganized the field crew to perform quality work within a reasonable budget. During this same period. he had to receive feedback from field crews at two other sites and confer with them daily on the schedule of activities charted for the following one month. Additional projects with similar responsibilities include: Characterization and Remedial Alternatives Evaluation for hazardous waste sites at Moyer Landfill Superfund Site, PA and Reich Farm Superfund Site. NJ. Preferred Area Environmental Assessment, Environmental Impact Statement for three US Postal facilities in New York State. Supervise property surveys/stakeout for nearly 20 projects. Design Experience • While in India, Dr. Ganapathi designed, conducted field survey. supervised construction and operated a low cost oxidation ditch for treating campus wastes for over two years. He also Gomes Ganapathi Page Four designed for and evaluated the performance of a series of oxidation ponds (anaerobic, facultative, and aerobic) for treating municipal septic tank effluents. The study involved use of oxidation pond effluents for pisiculture and horticulture. He also played a key role in the design of distribution network for water supply system involving small communities and package water treatment units. • Dr. Ganapathi was the field team leader for the EDM survey and levelling and the lead engineer for the design of storm sewers for the following New York State Department of Transportation routes: Transit Road (1.2 miles • Route 78), Buffalo. New York Jamestown (2.5 miles• E/W Arterial), New York The designs involved estimates of runoff, sizing of pipes, placing manholes and catch basins. and design of culverts. • For the Novaco Superfund site, Dr. Ganapathi estimated the volume and direction of contaminated groundwater plume due to hexavalent chromium.
