2.3 Stakeholders

Principal project stakeholders are listed below;

Property owner-The Chemours Company NJ Department of Environmental Protection (NJDEP) U.S. EPA Region II (EPA)

3.0 Background

The USACE is conducting the environmental remediation of the Site. Specifically, USACE is addressing radiological contamination at the Site, resulting from past uranium refinement processes performed for the Manhattan Engineer District (MED) and Atomic Energy Commission (AEC) in the early years of the nation’s atomic energy program.

Information regarding the investigative phase of the project along with the remedial action and the Record of Decision and a full description of the site can be found in the documents below:

Final Sitewide Remedial Investigation Report for All Operable Units, DuPont Chambers Works FUSRAP Site, Deepwater, NJ. Cabrera, June 2011

Final Dupont Chambers Works FUSRAP Site Proposed Plan. Cabrera November

See sections 10.2 and 10.3 for references to these and other project documents.

4.0 Site Conditions

4.1 Constituents of Concern

Under FUSRAP, the USACE is authorized to investigate and conduct a response action (including remedial action) only for those constituents of concern (COCs) resulting from past MED activities. The COCs for the DuPont Site are uranium including U-234, U-235, and U-238 as well as Th-230, and Ra-226. Constituents not associated with the uranium refinement processes at Chambers Works may be remediated only if commingled with the above MED-related COCs. If commingled, the non-MED constituents will be removed along with FUSRAP eligible contaminants to the extent necessary to accomplish the FUSRAP response action.

The Contractor shall demonstrate compliance with cleanup criteria established in the Record of Decision (ROD) using final status surveys compatible with the Multi-Agency Radiation Survey and Site Investigation Manual and applicable or relevant and appropriate requirements (ARARs) at all areas addressed by this response action

4.1.1 Remediation Goals

The Remediation Goal (RG) for total uranium was calculated to be 65 picoCuries/gram (pCi/g) based on the most conservative (i.e., most protective) land use scenario, the construction worker. The 65 pCi/g RG for total uranium includes contributions and considerations of the other two COCs (Th-230 and Ra-226). Therefore, there is no need for separate RGs for Ra-226 and Th-230. Meeting the total uranium RG will reduce risk and exposure and meet the dose limit for all COCs. This means that the soils in OU 1 and AOC 6 that exceed a concentration of 65 pCi/g total uranium will be addressed during the remedial action. The RG of 65 pCi/g total uranium was used to develop soil volume estimates and will form the basis for confirmatory sampling during the final status survey.

4.1.2 FUSRAP-Contaminated Media/Areas

FUSRAP-contaminated media (soils, sediments, fill and debris) is defined as media located in areas of the DuPont FUSRAP Site that correspond to previous MED disposal activities, material handling activities, and sediment transport by site drainage features that exceed the clean-up goals as specified above in Section 4.1.1.

OU1 has two Areas of Concern (AOCs) with uranium contamination detected at depths up to 5.5 feet below ground surface (bgs) in AOC 1 and to a depth of 11 feet bgs in AOC 2.

Maximum uranium concentrations in AOC 1 and AOC 2 were reported as 677 picocuries per gram (pCi/g) and 16,584 pCi/g, respectively. The soil contamination had originally been estimated in the RI (CABRERA, 2011b) to encompass approximately 1 acre within AOC 1 and 1.7 acres within AOC 2, however recent work at AOC 1 (See ECC, March 2016) has shown the soil contamination to be much more extensive than anticipated. Note that the Central Drainage Ditch (CDD) runs through AOC 1 with the contaminated soil and sediments from that area of the CDD considered part of the AOC 1.

Soils in AOC 6 which is comprised of Survey Units (SU) 4 and 5 were contaminated above the investigative screening level at depths less than 11 feet bgs. The highest concentration of total uranium was 3,910 pCi/g at 1 foot bgs. The total area of soils impacted was originally estimated to be approximately 0.1 acres but was found to be significantly larger during the initial cleanup. Survey Unit 4 has already been fully remediated (See ECC, March 2016). Survey Unit 5 of AOC 6 has been partially remediated and will be completed under this contract. SU 5 currently contains ponded water and plastic lining the excavation sides of the pond. The cleanup of the FUSRAP AOCs 1, 2 and 6 will be in accordance with the ROD.

4.2 Current Site Conditions

During the execution of the 2013 remedial activities, several excavations were started in two separate areas of the Chambers Works site currently controlled and fenced off by USACE. The first area was AOC 6 of OU 3, located on the eastern portion of the Site.

This area is also known as the eastern burial area. The second area consists of AOC 1 and AOC 2 of OU 1, located in the northwest quadrant of the Site. This area is also referred to as F-corral. Two excavations in AOC 1 and one excavation in AOC 6 currently remain open and contain ponded water. Potentially contaminated soils along the excavation sidewalls have been covered with plastic.

Also within the fenced area of F-corral are the existing site work trailers, which are currently being maintained by the FUSRAP interim O&M contractor, the Waste transfer Facility (WTF) and the Construction Water Treatment Plant (CWTP). The WTF was constructed to facilitate loading of gondola cars. 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.

Current site conditions, including estimated remaining volumes for each AOC, are detailed in the former RA Contractor-prepared closure report, As Left Report, Remediation Services Formerly Utilized Sites Remedial Action Program (FUSRAP) at the DuPont Chambers Work Site, ECC, March, 2016. This report includes Chambers Works site figures, RA radiological data for all completed efforts. This contract is intended to be used to complete the remediation at the site. The former RA contractor estimated that up to 50,000 cy of in-situ soil will need to be excavated to complete remediation at the DuPont Chambers Works site. While reasonable methods were used to calculate the additional quantities, it is expected that the actual final quantities may be different. The following is a brief summary of the current status and remaining work at each FUSRAP AOC at the DuPont Chambers Works site.

4.2.1 Area of Concern 1

AOC 1 was subdivided by the previous contractor (ECC, June, 2016) into two smaller Survey Units, SU3 (about 2,000 sy) and SU3A (about 3,000 sy). SU3 is an area which contains foundation debris associated the original processing facility including Former Building 845 and other smaller structures located on the site. SU3A is an approximately 0.6 acre area located southwest of SU3. The west side of SU3A borders the CDD. CABRERA proposed primary cut lines in AOC 1 (CABRERA, 2012) which included the two areas that ECC labeled SU3 and SU3A. Note that the winning bidder of this scope of work may choose to define survey units differently than the previous contractor, thus the discussion of survey units in this scope of work is for purposes of clarifying the work already completed.

4.2.1.1 Survey Unit 3

SU3 was test pit sampled down to 2 or 4 feet (depending on the primary cut depth) and determined to be non-RCRA contaminated. Uranium levels were found in layers well above Unimportant Quantity of Source Material (UQSM) levels in thin layers and pockets.

SU3 contained significant quantities of intact and broken concrete; much of the uranium contamination was found interspersed with this concrete and it appeared that subgrade process lines, containing more concentrated materials, were being exposed during excavation.

The area was excavated to a depth of approximate 7 to 8 feet bgs. At this depth a clay/sandy soil layer was reached and contaminant levels appeared to reducing in concentration, but contaminated soils still remain at the bottom and the excavation must proceed deeper. A live water line was found in the southeast portion of the SU3 and contamination remains around this pipe. During the 2015 site closure operations by the RA Contractor, the excavation sides were poly-lined. The area was barricaded off and posted as a radiological contamination and chemical exclusion zone. The current condition of SU3 can be found in the ECC as-left report. The RA contractor estimated that 5,100 cy of contaminated soils were still present at this survey unit and will require excavation.

4.2.1.2 Survey Unit 3A

The SU3A area contained higher level uranium contamination, which was homogenized by the RA contractor with lower activity material. This aggregated material was found to be an unimportant quantity of source material and was disposed of at the approved offsite facility. During the 2015 site closure operations by the RA Contractor, a “jersey barrier wall” was placed between SU3A and the CDD. This barrier wall was lined with clean gravel/soil and then poly-lined. The excavation faces were also poly-lined. The entire SU3A area was barricaded off and posted as a radiological contamination area and a chemical exclusion zone.

The current condition of SU3A can be found in the ECC as-left report. ECC provides figures showing the as-left or near-to-as-left gamma walkover data, the primary cut line boundaries, the exclusion zone boundaries, and the projected areas were more excavation may be required. The majority of SU3A has been remediated. The RA contractor estimated that an additional 1,500 cy of contaminated soils were still present at this survey unit and will require excavation.

4.2.2 Area Of Concern 2

AOC 2 is bounded by the CDD on the north, east and west sides and by the CWTP to the south. The area is covered with an asphalt cap. Sheet piling was driven to a depth of between 40 to 60 feet to conservatively surround the area where the primary excavation area was expected to be 12 feet bgs. This sheeting was installed to support the excavation sidewalls and minimize the dewatering needed during remediation. The sheet pile was installed by excavating a 6’ deep trench along its alignment. Significant quantities of concrete block, footers, and construction debris were encountered and removed during the trenching. Soils and debris removed from the trench were replaced with clean soil, and the steel sheet piles were driven through this clean soil.

Test pits were excavated at multiple locations to characterize the soil in AOC 2. These pits were to a depth of 2 feet bgs in the eastern half of AOC 2 (where excavation is anticipated to be relatively shallow) and to 4 feet bgs in the western half of AOC 2 (where excavations are planned to a depth of 12 feet). Both halves were found to not contain RCRA wastes, but did contain pockets of higher concentration uranium bearing material. The western half of AOC 2 is known to contain petroleum distillates at depth (greater than the 4’ initial test pit depth) and thus this initial waste determination may not be applicable beyond the planned shallow excavation. Other than the test pits and the trenched areas, AOC 2 remains largely covered with clean gravel on top of the original asphalt cap, and AOC 2 has not been remediated. The remaining work and logistical constraints at AOC 2 include:

Contaminated AOC 2 soils must be excavated and removed to a depth of approximately 12’ bgs within the sheet pile area, and 4’bgs outside the sheet pile.

The RA contractor estimated that an additional 15,000 cy of contaminated soils were still present at this survey unit and will require excavation.

Site drainage around this area will need to be maintained during remediation.

Access to the WTF (or another waste load out facility) will need to be maintained during remediation.

Significant groundwater intrusion may be possible.

Access to the CWTP will need to be maintained during remediation.

An active 18” water main surrounds the western half of AOC 2 – care when working near this main is required.

A significant layer of coal tar is expected to be present in the 12’ bgs portion of the excavation.

A final status survey will have to be developed to assess the area against the remediation goals.

Excavation activities near the rail line could present rail-way bridge integrity concerns. If necessary, the contractor will be responsible for supporting the rail bridge during excavation to maintain its integrity. This may require the Contractor to provide a design to ensure the structural integrity of the railway.

4.2.3 Area Of Concern 6

Two SUs are located at AOC 6, SU4 and SU5. These SUs are former burial sites that were believed to contain uranium process materials transported there from AOC 1 and AOC 2.

4.2.3.1 Survey Unit 4

The previous RA contractor completed the remediation at SU4. A total of 2,700 cubic yards of contaminated soils were excavated and disposed of. The Final Status Survey (FSS) of SU4 indicated that the remedial goals were achieved and the areas has been backfilled and graded. No additional remedial work in this area is expected at this time.

The FSS completed by the previous contractor will be provided to the new contractor. The new Contractor shall complete a final release document.

4.2.3.2 Survey Unit 5

SU5 was partially excavated to a depth of 9 to 13 feet by the former RA contractor and contamination remains at SU5. The open excavation at SU5 is currently a water-filled pit with a berm around the perimeter. During the excavation of SU5, rusted portions of drums and one intact stainless steel drum were commingled with FUSRAP waste. More rusted non-intact drums are clearly still present in SU5. Significant levels of TEL and noxious odors encountered during the partial excavation of SU5 necessitated the former RA contractor to perform most of the work in Level C personal protection, and the former RA contractor had to use odor control foam in this area to reduce odors to an acceptable level.

In addition to drums, the former RA contractor also encountered raw chemicals/free product, oil, construction debris, and coal tar while excavating at SU 5.

The current status of SU5 is discussed in the ECC As-left report. The RA contractor projected that 4,200cy of contaminated soil remains in SU5. The remaining estimated contaminated soil is more fully defined in Table 1.
