PURPOSE

The Remedial Program Managers (RPM) for the Comprehensive Environmental Responsibility, Compensation and Liability Act (CERCLA) actions are responsible for identifying, investigating and defining sources of contamination, designing, constructing, and operating remedial action systems located at the Federal Aviation Administration William J. Hughes Technical Center (WJHTC). Existing WJHTC resources are either technically not equipped for this effort or are inadequate to meet the demands for supporting the CERCLA program requirements.

The CERCLA RPM utilizes the services of various contractors to support the accomplishment of this mission. The identification, investigation, delineation of contamination, and the design of remedial action systems are performed by an environmental architect and engineering firm under separate contract. The Environmental Remediation Support Services (ERSS) is required to provide the necessary resources to the WJHTC, in the form of operation and maintenance, remedial action system construction, and geographic information system support. Currently, each site requiring remediation requires a separate contract for operation and maintenance and construction.

1. DESCRIPTION OF WORK

1.1. General

The objective of this procurement is to have a Contractor that has the personnel and corporate resources to perform the required operations and maintenance, remedial action construction and Geographic Information Systems/Global Positioning System (GIS/GPS) related tasks for the Federal Aviation Administration (FAA) William J. Hughes Technical WJHTC (WJHTC). The WJHTC is listed on the Superfund National Priority List (NPL) and the majority of the work will be in Areas of Concern (AOCs) undergoing active remediation. At this time, the Operations and Maintenance Contractor (OMC) must ensure that the following requirements are met:

• All operating personnel qualifications and experience are approved and personnel are trained.

Personnel qualifications must meet the requirements specified elsewhere in this Statement of Work (SOW).

• The remedial systems are operated in accordance with CERCLA Substantive Requirements (APPENDIX A) Evaluation and Operational Strategy Plan (dated November 2013).

• The Operations and Maintenance (O&M) manuals, Site Health and Safety Plan (SHASP), Sampling and Analysis Plan (SAP) (APPENDIX B), Operation Strategy Plan (Op Plan), and Staffing Plan (as described in Section 8.0) are reviewed and approved by the government.

1.1.1. Description of Areas of Concern (AOCs)

The following sections provide a brief history of the FAA’s current active remediation. Additional information for each AOC is located in the current Five-Year Review (APPENDIX C). Treatment system diagrams have been included in APPENDIX D.

1.1.1.1. Area D – Jet Fuel Farm)

Area D is the site of a former Jet Fuel Farm for the storage of aviation fuel (JP-4). Before 1972, fuel was stored in two 567,000-gallon underground storage tanks (UST). In the mid-1970’s the fuel was stored in two 420,000- gallon bermed above-ground storage tanks (AST). The use of the ASTs was discontinued in 1994, and the USTs were abandoned in place in 2000. A surface spill of jet fuel (approximately 25,000 gallons) occurred in 1982. The Phase I and II site investigations were conducted in 1988 and 1989, respectively. Field investigations have identified several separate petroleum hydrocarbon sources associated with the ASTs, USTs, or former fuel farm activities.

Separate phase floating hydrocarbon true product thickness was estimated to be between three

(3) and five (5) feet, but observed product thickness has been as thick as 15 feet. Elevated levels of total xylenes (benzene, ethylbenzene, toluene, and total xylenes) have been observed both in the groundwater and in the soil. In September 1989, a Record of Decision (ROD) was issued by the United States Environmental Protection Agency (USEPA) for Area D. The remedy selected by the ROD included free-phase product (jet fuel) extraction and off-site disposal, soil venting, and groundwater extraction and treatment and injection with in situ bioremediation.

To expedite the remediation of Area D, the FAA commenced operation of a Thermal Conductive Heating (TCH) system in March 2019. The TCH system is being operated to treat free-phase product, soil contamination, and groundwater contamination. The TCH system remedial action is a multi-phase project and is expected to be completed and removed from service in December 2020.

1.1.1.2. Area B – Navy Fire Test Facility

Area B is located on the New Jersey Air National Guard side of the Technical Center and along the South Branch of Absecon Creek. The Area B site was historically used as a fire training facility during the late 1950’s and early 1960’s. By 1965, the area had been graded over. A portion of the site was later used for General Services Administration (GSA) motor pool parking, but that operation has ceased. Past activities have impacted the groundwater with chlorinated solvents. In 1996, a ROD was issued by the USEPA for Area B. The remedy selected by the ROD included air sparging with on-site vapor treatment, if necessary. As a result of additional pre-design studies, the FAA implemented contingency remedies documented in the ROD, including the following components:

• Installation of additional monitoring wells;

• Continued groundwater and surface water monitoring;

• Installation and operation of product/groundwater extraction wells;

• Physical separation of product and off-site transport for incineration;

• Groundwater treatment;

• Discharge of treated water back into the groundwater; and

1.1.1.3. Area 41 – AVGas Fuel Farm and Photo Lab

Area 41 is also located on the New Jersey Air National Guard side of the Technical Center. Area 41 consists of a former aviation gasoline (AVGas) fuel farm, a photographic laboratory, and historic impoundment area. The fuel farm consisted of three (3) 50,000-gallon underground storage tanks (USTs) and two (2) 100,000-gallon USTs, all of which were installed in the mid-1940’s. Closure of the USTs in accordance with New Jersey Department of Environmental Protection (NJDEP) regulations was completed in November 1999. In 2000, a ROD was issued by the USEPA for Area

41. The remedy selected by the ROD included:

• Excavation of approximately 450 cubic yards of PCB-contaminated soil and sediment from two drainage ditches and transport off-site for disposal at a licensed facility;

• Excavation of approximately one (1) cubic yard of soil from a former UST sump outlet contaminated with total petroleum hydrocarbons and transport off-site for disposal at a licensed facility, provide the soil was not removed during tank closure activities;

• Backfilling of a man-made depression area and associated drainage ditch with clean soils;

• Excavation of free petroleum product present on the water table in both a former impoundment area and the fuel farm area and transport off-site for incineration at a licensed facility;

• Extraction of contaminated groundwater in the former impoundment and fuel farms areas with on-site treatment using carbon adsorption and filtration; treated groundwater will be recharged to the subsurface in the vicinity of the site with the possible partial discharge of treated groundwater to the sanitary sewer.;

• Establishment of land use restrictions to prevent residential use of the site; and

1.1.1.4. Area E – Building 11 Tank Excavation Area

Area E is also located on the New Jersey Air National Guard side of the Technical Center. Area E is the site of a former heating plant and wooden structures, reported to be barracks. The heating plant and a 20,000-gallon UST that stored No. 6 fuel oil for heating operations were removed in 1985 and the fuel was found to have leaked from the tank, impacting subsurface soil and groundwater. The barracks and other wooden structures were removed at the same time as the heating plant, and soils and groundwater were found to be impacted with petroleum hydrocarbons, pesticides, volatile organic compounds (VOCs) and metals. In 2003, a ROD was issued by the USEPA for Area E. The remedy selected by the ROD included:

• Free product extraction and off-site treatment;

• Excavation of petroleum-contaminated soils which exceed New Jersey non-residential direct contact soil clean-up criteria and off-site beneficial reuse or off-site disposal;

• Excavation of pesticide-contaminated surface soils which exceed New Jersey non-residential direct contact soil clean-up criteria and off-site disposal;

• Groundwater extraction;

• On-site groundwater treatment using filtration and carbon adsorption, if necessary;

• Reinjection of treated groundwater;

• Extraction well installation and continued groundwater monitoring;

1.1.1.5. Area 20A – Salvage Yard

Area 20A is located on the west side of Pangborn Road in the Technical Center’s Research and Development Area at the Atlantic City International Airport in Atlantic City, New Jersey. Past activities at Area 20A (Salvage Yard) have resulted in contamination of soil and ground water by Chlorinated Volatile Organic Compounds (CVOCs). In 1990, a ROD was issued by the USEPA for Area 20A. The remedy selected by the ROD included:

• Excavation of approximately 930 cubic yards of soil and transport off-site for incineration at a permitted rotary kiln; and

• Air stripping of organic compounds in the groundwater.

The OMC will be required to conduct meetings on a weekly basis to provide the FAA with an overview of the status of the CTP and Area 20A remediation systems, and any remedial action construction projects in progress. The OMC is responsible for providing the COR the Weekly Progress Meeting Minutes per the Deliverables Schedule.

1.2.1.3. Discharge Monitoring and Reporting

The OMC must provide all labor, materials, equipment, technical expertise, and supervision necessary to perform all sampling per the Operational Strategy Plan, and per local, State, and Federal laws and regulations. The OMC must provide a full-time (40 hour/week) Quality Control Supervisor and a full time Field Sampler/Technician. The OMC must perform sampling per the Operational Strategy Plan (see Appendix A) and per the approved Sampling and Analysis Plan (SAP) (see Appendix B). The OMC must use only one (1) NJDEP certified laboratory for all subcontracted sample analysis, and the OMC must follow all NJDEP and EPA protocols. The OMC must complete all sampling per the current NJDEP Field Sampling Procedure Manual and EPA Region 2 Low-Flow Sampling Procedure, which includes collecting:

• Quality assurance/quality control (QA/QC) samples;

• Water Quality Indicator Parameters (WQIPs); and

• Groundwater elevation measurements;

The OMC must notify the COR immediately if the analytical results for the effluent sampling does not meet the requirements set in the Operational Strategy Plan. If this occurs, the OMC must provide the COR a strategy to come back into compliance with the Operational Strategy Plan.

1.2.1.4. Equipment and Supplies

The OMC must supply the following products, equipment, chemicals, supplies, and other necessary items as part of the O&M costs for the two (2) remediation systems.

1.2.1.4.1. Treatment Process Chemicals

Organo-clay

The PV-2000 Organo-clay media vessel is charged with 2,000 lbs. of EC-100 organo-clay media or equal. The media is to be a blend of bentonite and anthracite treated with quaternary amine.

The media removes emulsified oil and grease and large molecular chlorinated hydrocarbons. The organo-clay vessel filters only influent extracted from Area D. Historical change outs average four

(4) over a two-year period.

Filter Press Precoat:

If necessary, provide a material in granular form that mixes directly with water and can be easily fed into the filter press inlet and approved for this application. The use of precoat, the material and application rate must be approved by the COR. Historical disposals average twenty (20), one (1) cubic yard boxes over a two-year period.

Polymer

Polymer (Zeta Lyte1A) is currently mixed on-site. The annual yield is approximately fifteen (15) gallons.

Manganese Greensand Filters

Due to the current pumping requirements, the greensand filtration system is being bypassed and is not currently being utilized at the CTP. Therefore, pricing for material changeouts of manganese greensand must not be included within the Contractor’s bid. However, for informational purposes, the filters use the continuous regeneration (CR) method; iron is oxidized by potassium permanganate, followed by physical removal of the resulting precipitates by filtration using a manganese greensand bed. The manganese greensand is constantly regenerated by the addition of potassium permanganate.
