Performance Work Statement

Remediation Services

1.0 PROJECT OVERVIEW

The United States Army Corps of Engineers (USACE) is conducting the environmental restoration of the former DuPont Chambers Works Formerly Utilized Sites Remedial Action Program (FUSRAP) site. USACE is addressing radiological contamination at the site, resulting from past uranium refinement, scrap recycling and research performed for the Manhattan Engineer District (MED) and Atomic Energy Commission (AEC) in the early years of the nation’s atomic energy program. USACE is issuing this Performance Work Statement (PWS) under the requirements of the CERCLA of 1980, as amended, 42 United States Code (U.S.C.) § 9617(a), and the NCP, 40 CFR § 300.430(f)(2).

1.1 Background

The former DuPont Chambers Works site is an active chemical manufacturing facility, located in Salem County, New Jersey now run by Chemours. In the 1940s, E. I. du Pont de Nemours and Company performed work for the Federal Government in support of the nation’s early atomic energy program. The USACE is addressing residual radioactive contamination in specific areas of the property under the FUSRAP. The areas are collectively referred to as the DuPont FUSRAP site.

USACE identified the FUSRAP-eligible constituents of concern in site soils that were related to the uranium processing and research activities at the site and that could pose a risk to human health under an industrial land use scenario. Constituents of concern are uranium, thorium, and radium;

specifically Uranium-234 (234U), Uranium-235 (235U), Uranium-238 (238U), Thorium-230 (230Th), and Radium-226 (226Ra). The Remedial Action (RA) recommended in the Proposed Plan and selected in the Record of Decision, signed on September 12, 2013, only addresses these FUSRAP-

PWS TO 2 (revised).docx2 eligible constituents of concern and does not address other hazardous contaminants that may be present at the site.

1.2 Prior Remedial Action

A Remedial Action contract was awarded in 2013. The Contractor began performing work in 2014, with excavations commencing in the fall of 2014. In the winter of 2015 previously unidentified areas of contamination were found, nearly doubling the estimated volume of waste to be excavated under the contract (from 25,000 cubic yards (cy) to almost 45,000 cy). Of this volume, approximately 27,000 cy of soil (in situ) remains to be excavated and disposed offsite. Contract capacity and funding for the increased work was insufficient and the contract was ultimately terminated for the convenience of the Government.

During the execution of the remedial activities, several excavations were started in two separate Areas of Concern (AOCs) of the site currently controlled and fenced off by USACE. The first is AOC 6 of Operable Unit (OU) 3 and is located on the eastern portion of the Chemours facility; this area is also known as the eastern burial area. The second area consists of AOCs 1 and 2 of OU1 and is located in the northwest quadrant of the Chemours facility; this area is also referred to as F-corral. Two excavations in AOC-1 in F-corral and one excavation in AOC-6 currently remain open and contain ponded water; potentially contaminated soils along the excavation sidewalls are covered with plastic liner.

Also within the fenced area of F-corral are the existing site work trailers, the Waste Transfer Facility (WTF), and the construction water treatment plant (CWTP). The WTF consists of an elevated platform which can store about 1,000 cy of contaminated soils, is used for loading of contaminated soils into railcars, and is located directly adjacent to the rail spur. The CWTP was successfully used to treat groundwater from the excavations; this plant has been drained and shutdown and routine maintenance activities are being conducted to ensure viability of the plant for re-start. Additionally, some rental components were demobilized from the CWTP and will need to be replaced (as part of this task order).

As-left site conditions, including estimated remaining volumes for each AOC are detailed in the Contractor-prepared closure documents, including site figures prepared by the previous Contractor.

Additionally, RA radiological data is available to document all completed efforts .

2.0 SCOPE OF WORK:

The contractor shall provide qualified personnel to complete the major work items listed in this section as part of this task order. Note that this task order will be for work performed within one year from award. Follow-on task orders for additional years of work may be issued at a later date by the Government.

2.1 Detailed Scope

The scope of services includes but is not limited to, the following activities related to the RA at the DuPont FUSRAP site:

PWS TO 2 (revised).docx3

1. Excavation of contaminated soils with total uranium concentrations above the remediation goal of 65 picocuries/gram (pCi/g).

2. Physical separation and management of excavated material to minimize Class 7 radioactive materials and mixed waste. The mixed waste which includes both radiological and chemical constituents (note updated regulatory guidance) is more expensive to dispose of.

3. Loading excavated soil into rail cars at the WTF.

4. Transporation of individual rail cars within the project area for loading and staging.

Chemours rail services will transport the cars from the F corral location to the Chemours entrance.

5. Transportation of excavated soils by rail to an off-site licensed/permitted disposal facility.

6. Disposal of excavated soils at an off-site licensed/permitted disposal facility approved by the

USACE.

7. Backfilling and compaction of excavated areas with approved backfill.

8. Reactivation, operation and maintainance of the onsite construction water treatment plant

(CWTP); This includes mobilization to the site of any groundwater treatement plant units that were rented and demobilized by the previous Remedial Action Contractor.

9. Recovery of groundwater, some storm water, and non-aqueous phase liquids and treatment of recovered water in the CWTP.

10. Treatment of liquids at the CWTP to meet groundwater treatment permit levels. It is the Contractors responsibility to provide a CWTP that can adequately process contaminated surface or groundwater.

11. Testing and release of treated water treated in accordance with the site NJDEP discharge criteria into the Central Drainage Ditch.

12. Further delineation of radiologically contaminated areas.

13. Removal of substantial concrete foundations within excavation area.

14. Removal of partially intact chemical drums that are currently visible and others that are not yet known.

15. Possible removal of fully intact chemical drums (which may be encountered in the future).

16. Excavation work in level C.

17. Possible excavation work in level B.

18. Recovery of floating free-phase product in water-filled excavations to the extent necessary to complete the excavations.

19. Disposal of free-phase product which has been separated from water in the treatment plant.

20. Diversion of the Central Drainage Ditch is part of the upcoming work.

21. The Chemours facility has very antiquated infrastructure which will likely affect the upcoming excavation. Problems encountered in the past include;

a. Large Chemours clean water pipes leaking into excavations.

b. On-site Chemours building adjacent to WTF with an exterior wall leaning towards

WTF.

c. Cracks on retaining wall between RR tracks and WTF

d. Railroad track replacement.

22. Performance of a final status survey to verify that the completed RA meets the soil remediation goal in accordance with MARSSIM requirements;

23. Restoration of site to pre-existing conditions or as otherwise directed by USACE including:

a. Backfill and compaction of all excavations.

b. Note that three open excavations are present at the site, for these excavations, pre-existing shall be defined as their conditions prior to any excavation that has already

PWS TO 2 (revised).docx4 occurred.

24. Implementation of land use controls to limit potential onsite exposure to contaminants during

RA activities.

25. The contractor is responsible for backfilling the site with a Government-approved backfill material.

26. The contractor is responsible for compliance with all existing permit equivalents (found in task order #1).

27. Potential additional future work could include further excavation/delineation. The furthest extents of contamination will determine if potential additional work will be needed. That work could include items such as;

a. Demolition and construction of a small railroad bridge over the Central Drainage Ditch

b. Excavation under railroad tracks followed by replacement of Railroad tracks.

c. Excavation of contamination under active Chemours pipe racks

Note that the potential contamination under the railroad tracks and adjacent to the railroad bridge could cut off the WTF from the rail line requiring an alternate loading area

The scope of this work does not include addressing non-FUSRAP-related contamination that may be associated with past DuPont FUSRAP site chemical manufacturing operations unless it happens to be commingled with materials related to the FUSRAP remediation. Non-FUSRAP contaminants will be removed along with the eligible FUSRAP contaminants only to the extent necessary to successfully complete the FUSRAP response action. Comingling can be found in both soils and groundwater. Free-phase product has been found at the site in soil, groundwater and surface water which must be addressed as necessary. Free-phase product shall be only removed when it is within excavated soils, enters the CWTP, or is found floating on the surface water within excavations and must be removed to complete the excavation.

3.4 Implementation

The Contractor shall implement RA activities in accordance with the approved Work Plans, in order to meet the objectives of this PWS.

3.4.1 Excavation and Backfilling (WAD 2)

The Contractor shall implement the work at the DuPont FUSRAP site in accordance with the approved Work Plans and associated permits. The contractor shall be required to obtain excavation permits, work permits, and hot work permits from Chemours for the work required under this task order. Work cannot proceed until after permit approval by Chemours.Also, the contractor shall be required to perform all site operations in accordance with existing NJDEP permit equivalent requirements. All NJDEP permit equivalents will be obtained/updated as needed, and adminsistered under Task Order #1 (see section 2.5 Task Order #1).

Approximately 27,000 cubic yards of waste materials are anticipated to require excavation during completion of the RA activities under this contract. USACE anticipates that approximately 4,500 cubic yards of soil shall be excavated, and that approximately 4,500 cubic yards of clean soil shall be imported and used as backfill during this task order. Table 1 lists and provides volume estimates (for bidding purposes only) of waste quantities to be excavated by area.

3.4.2 Waste Loading, Transportation and Disposal (T&D) (WAD 3)

USACE anticipates that approximately 4,500 cubic yards of waste soil shall be loaded, transported, and disposed offsite during this task order. This is further divided into an expected 2,250 cubic yards of mixed (chemical and radiological) waste and 2,250 cubic yards of radiologic waste.

PWS TO 2 (revised).docx8

Transportation to the selected disposal facility will occur by rail-only. The Contractor will be required to, at a minimum, package waste shipments and load railcars. The contractor shall provide a unit price (per cy) for waste loading. The transportation subcontract will be awarded dependent upon the selected disposal facility(ies). The Contractor shall provide a price for disposal per cubic yard of both mixed waste and radiological waste based on competitive bidding. The proposed transportation subcontract need to include specific discussion of demurrage. Due to recent regulatory guidance, the Contractor should pay particular attention to 49 CFR § 173. The Contractor shall consider the most cost-effective transportation and disposal options.

The Contractor must clearly define the costs for demurrage including rail car demurrage. The Government believes demurrage can be avoided, however if the contractor plans on having demurrage fees as a part of their bidding strategy, these costs must be included in the contractor’s bid.

The Government intends to solicit T&D services concurrent with this solicitation against the Multiple Award Radiological Transportation and Disposal Services (MARTADS) contract in order assess and select the most cost effective pricing for T&D efforts at DuPont FUSRAP. If the T&D option is provided by the MARTADS, the contractor will be required to coordinate with a separate T&D contractor regarding waste shipments. For purposes of bidding the Contractor shall assume that T&D efforts are to be included in their proposal..

3.4.3 CWTP Operations and Maintenance (WAD 4)

The Contractor shall utilize the CWTP that currently exists on site for the duration of the field effort defined in this task order. Records of operation of the CWTP by the previous contractor showed that the volume of water treated under batch conditions was generally in the range of approximately 200,000 gallons per month, while volume under continuous treatment conditions was up to approximately 800,000 gallons per month. USACE expects that the CWTP will be operated, at least initially, under batch conditions, thus it is more likely that the contractor can expect to treat up to approximately 200,000 gallons per month.

The Contractor shall follow the USACE-approved O&M plan submitted in Task Order #1. Future modifications of the CWTP may be required to address additional contaminants which may be encountered during removal of waste. For purposes of bidding, it should be assumed that no additional contaminants will be encountered. Additional possible efforts specified in section 4.1 are possible such as excavation under an in-sevice pipe rack plus excavation under and possible replacement of a small rail bridge. For bidding purposes these items are not to be included.

The contractor shall be required to:

Perform startup of CWTP including mobilization of rental equipment that had previously been removed from the site, reassembly of all components, verification of operability of components including mechanical, electrical, computer, plumbing connections, etc.

Operate CWTP with proper personnel including oneoperator with NJDEP WWTP N-3-rated operator license, one operator with NJDEP WWTP N-2-rated operator license, plus any other required personnel such as electrician, plumber, mechanic, computer IT, etc.

Treat water from excavations and accumulated rainwater runoff to meet the site specific NJDEP treatment and discharge limits of the permit

PWS TO 2 (revised).docx9

Stock required chemicals and supplies Obtain required subcontracts Develop strategies for storing, treating, and discharging water in batch mode (initially), and possibly continuous mode later on.

Perform data collection and comply with storage and system documentation requirements

The CWTP requires licensed N3 operators to run the plant. The Contractor shall be responsible for all Operations and Maintenance of the CWTP and all infrastructure required to store and transport water to the CWTP. While the CWTP has had heat tracing and insulation installed, it is not entirely freeze proof, and the contractor may need to supplement this freeze proofing to the extent necessary. The It is the contractor’s responsibility to keep the CWTP and associated piping and tank in operation, if required, during the winter months. In the event that work is stopped and the CWTP is shut down for the 3-month winter period, freeze protection will not be required. Under this scenario, the CWTP tanks and lines will need to be drained.

3.4.4 Restoration (WAD 5)

The Contractor shall implement the Site Restoration Plan to return the site to previous conditions, or as otherwise directed by USACE. Restoration shall include compaction required for adequate resurfacing with no permanent water-filled depressions associated with subsurface settlement for a period of one year. Areas of the site where soil has been excavated (including the three currently open exavations) will be backfilled and compacted in controlled lifts with clean soil from a USACE-approved off-site source and returned to its present condition. All backfillmust meet New Jersey Insdustrial standards. The Contractor should assume that site restoration will be completed at the surface with six-inches of gravel. The only exception to this would be in the event that excavation occurs in a roadway, however this is not anticipated. The clean fill material shall be tested prior to placement to ensure it meets the above criteria.

3.5 Fixed Fee (WAD 6)

This award will be a cost plus fixed-fee service contract. The Contractor shall provide separate accounting for all fee-bearing activities.
