2 STATUTORY AUTHORITY, REGULATORY COMPLIANCE, AND ADMINISTRATIVE

RECORD

2.1 Statutory Authority

The DPG is located in southern Tooele County, Utah. This project is authorized under DERP, which was established by Congress in 1986 to provide funding to cleanup active DoD sites that fall under the jurisdiction of the Secretary of Defense.

The Record of Decision (ROD) presents the U.S. Army (Army) Selected Remedy for Area 2 of SWMU- 11 at DPG, Dugway, Utah. Records indicate Area 2 was never licensed by the U.S. Nuclear Regulatory Commission (NRC). During 2016, the Department of Defense (DoD) and the NRC finalized a memorandum of understanding (MoU) for the coordination of response actions for DoD sites containing radioactive material that are not licensed by the NRC (NRC-DoD MoU, 2016). The Remedy was selected pursuant to the MoU and in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended by the Superfund Amendments and Reauthorization Act (SARA) of 1986, and to the extent practical, the National Oil and Hazardous Substances Pollution Contingency Plan (NCP) – 40 Code of Federal Regulations (CFR) Part 300, and the U.S. Environmental Protection Agency (EPA) Remedial Investigations (RI)/Feasibility Study (FS) Guidance 540/G-89/004 (EPA, 1988).

The ROD is based on the administrative record for Area 2 of SWMU-11.

2.2 Regulatory Compliance

The Contractor will comply with all applicable federal, state, and local regulations while performing radiological remediation services required by this PWS. The Contractor will bear sole responsibility for any non-conformance resulting from the actions or directions of their employees or subcontractor employees.

2.3 Administrative Record

The primary documents pertinent to this work are included as Government Furnished information in Attachment 3.

The complete administrative record file for DPG contains documentation used in the decision-making process for the site. DPG maintains this administrative record, which is available for public review.

Supporting agencies, consisting of the Utah Department of Environmental Quality (UDEQ) Division of Waste Management and Radiation Control (DWMRC) and the NRC, concur with the selected remedy.

3 SITE BACKGROUND

In the DPG RCRA Facility Application, Area 2 of SWMU-11 was one of seven reported radioactive landfills. Historic records regarding radiological materials handling were summarized in the 2009 Phase II RCRA Facility Investigation (RFI) (Parsons, 2009). Specific records regarding radiological materials disposed at SWMU-11 are limited. The East Granite Holding Area (i.e., SWMU-11) is not identified in available literature as being associated with the testing of radiological munitions conducted at DPG in the 1950s and 1960s. Historical inspection records indicate that buried wastes in the SWMU-11 area consisted primarily of “contaminated rags and papers.” Inspection records from the U.S. Atomic Energy Commission indicate that low-level radioactive waste materials were repackaged for sea disposal in the Able Area. Waste from this activity may have also been disposed at the DPG burial area corresponding to SWMU-11 after the sea disposal program was discontinued. Available documentation states that operation of the DPG radioactive waste disposal facility was discontinued in the early 1960s and that materials were transferred offsite during 1962 (NRC, 2001). Historical records indicate that the latest potential use of the SWMU-11 area for radiation-related operations was 1977. By extension, the last potential opportunity for radiological material to be added to trenches TR-5 and TR-6 would also be 1977.

Radioactive waste materials from laboratory activities in other areas of DPG were stored in a CONEX container at SWMU-11 to protect individual storage containers from the elements. Materials stored in the CONEX container included Tritium and Carbon-14. In March 1980, contaminated glassware was removed from the CONEX by the DPG radiation safety officer and disposed at an off-site location.

During the 2005 Phase II RFI, no waste remained in the CONEX container (Parsons, 2009). The CONEX container was determined to be radiologically clear and was removed in 2017 (Marsh, 2017).

3.1 Current Site Conditions

The FS (North Wind, 2020a) evaluated human and ecological receptors and exposure routes, established remedial action objectives (RAOs), developed ARARs, and evaluated six remedial alternatives to address site-related contaminants that pose an unacceptable risk to human health or the environment.

As presented in the ROD, the conceptual site model (CSM) provides an evaluation of human and ecological receptors and exposure routes and RAOs were established based on the known current conditions and the potential risks to human receptors identified during the FS.

The Proposed Plan presented the findings of the FS (North Wind, 2020a). The PP identified the Preferred Alternative for addressing radiologically impacted soil and debris at Area 2 of SWMU-11 as Alternative 4 – Excavation, Disposal, and Backfilling. Alternative 4 meets the threshold criteria (i.e., overall protection of human health and the environment and compliance with ARARs) and provides the best balance of tradeoffs among the six alternatives with respect to balancing and modifying criteria (i.e., long- and short-term effectiveness; reduction of toxicity, mobility, volume, and mass of contamination;

implementability; and cost).

The Army selected Alternative 4 (Excavation, Disposal, and Backfilling) as the preferred remedy for Area 2 of SWMU-11. Excavation, Disposal, and Backfilling represents the best balance of tradeoffs between balancing and modifying criteria and will be protective of human health and the environment and will comply with ARARs.

3.2 Surrounding Properties

The DPG facility is bordered to the northeast by the Cedar Mountains and to the north-northwest by Wendover Air Force Range. DPG currently serves as the Army’s designated Major Range Test Facility for chemical and biological defense.

SWMU-11, also known as DPG-011 and the East Granite Holding Area, is located in the remote southwest portion of DPG and covers approximately 3.4 acres within a small canyon on the east side of Granite Mountain. SWMU-11 is divided into two distinct areas: Area 1 and Area 2. Area 1 of SWMU- 11 was previously evaluated and closed under the Resource Conservation and Recovery Act (RCRA) and corrective action requirements of the DWMRC. The focus of this PWS, Area 2 (0.86 acres) of SWMU-11 is a radiological disposal area of concern and consists of two trenches, TR-5 and TR-6, and the area adjacent to the trenches.

4 SITE CONDITIONS

4.1 Topography and Drainage

SWMU-11 is located at the mouth of a small, northeast-trending colluvial valley along the eastern side of Granite Mountain. The general topography at SWMU-11 is gently sloping down to the east, with an average elevation of 4,375 ft above mean sea level. The valley is flanked to the south by a small ridge of granite that extends from the main Granite Mountain area, and to the north and west by granite outcroppings characteristic of Granite Mountain. To the east, the valley is open to the broad expanse of the Dugway Basin. Granite Mountain is an isolated, north-south trending mountain block approximately 8 miles long × 6 miles wide. The southern two-thirds of the mountain are dominated by dark colored gneiss and gneissic granite with a thin sliver of schists and phyllites at the extreme southern end. The northern one-third of the mountain is made up of intrusive leuco-granitic rocks that form a gradational contact with the gneissic granite to the south. Quaternary-aged lacustrine, alluvium, and colluvium deposits are present along the flanks of Granite Mountain, including the small valley where SWMU-11 is located. Away from the mountain, the surrounding basin floor consists of aeolian sand and silt deposits, and Quaternary-aged playa and lacustrine sediments associated with deposits of ancient Lake Bonneville and older pluvial lakes (Parsons, 2009).

Groundwater in the area of SWMU-11 is part of the Dugway Valley aquifer system. Groundwater in this region is generally characterized by high total dissolved solids (TDS) and very flat hydraulic gradients.

However, the flanks of Granite Mountain, including the SWMU-11 site, constitute a local recharge zone for basin groundwater. In these localized zones, groundwater is deeper and of higher quality than groundwater beneath the basin floor. As groundwater flows from the local recharge area toward the basin floor, it becomes increasingly laden with dissolved mineral constituents; consequently, the quality of groundwater becomes greatly diminished. Depth to groundwater near the eastern boundary of SWMU-11 is approximately 61 ft bgs based on water-level measurements from MW-01. An attempt to install a second groundwater well in the western portion of SWMU-11 near TR-5 did not reach saturated conditions but rather encountered competent granite bedrock from 72.5 ft bgs to the terminal drilling depth of 90 ft bgs. Groundwater flow at SWMU-11 is likely to the east or northeast based on the local topographic gradient present at the site (Parsons, 2009).

4.2 Nature and Extent of Contamination

The various DERP soil sampling efforts identified soils in the SWMU-11 with elevated levels of Radium-226 (Ra-226), Lead-214 (Pb-214), Bismuth-214 (Bi-214), Strontium-90 (Sr-90) Niobium-94 (Nb-94), and Cesium-137 (Cs-137).

Maximum detected concentrations within the excavation locations included 3,040 picocuries per gram (pCi/g) for Ra-226, 2,200 pCi/g for Pb-214, 2,100 pCi/g for Bi-214, 19.2 pCi/g for Sr-90, 8.9 pCi/g for Nb-94 and Cs-137 was not detected in Area 2 but is likely associated with metallic debris in TR-6.

4.3 Selected Remedy

Based on the requirements of CERCLA and the NCP, and on a detailed analysis of the response alternatives using the nine criteria, the Army selected Alternative 4 (Excavation, Disposal, and Backfilling) as the preferred remedy for Area 2 of SWMU-11. Supporting information is presented in the ROD.

The major components of the selected remedy for the SWMU-11 include:

• Excavating approximately of 572 cubic yards (CY) from both TR-5 and TR-6 to a depth of approximately 7ft below ground surface (bgs) so as to meet RAOs.

• Temporary staging areas will be used to prepare impacted soil and debris for disposal and transport; these areas will be graded to reduce the potential for ponding and collapse of trench walls, lined to prevent groundwater contamination, and bermed to prevent runoff.

• Establishing perimeter dust control measures, air monitoring and contamination control measures to monitor and control the discharge of surface water runoff and airborne dust from the excavation areas to local conveyances. This will be conducted for health and safety purposes during excavation.

• To ensure the excavation was completed to meet unrestricted (i.e., residential) standards, or UU/UE, confirmation surveys and soil sampling for radionuclides and a magnetometer survey will be performed to ensure all radiologically impacted materials have been removed.

• Backfilling with clean soil, contoured to promote surface water runoff in accordance with the approved site restoration plan.

The Contractor will be required to meet the RAO, as stated in the ROD, to demonstrate completion of the contract:

• Prevent direct contact to or external exposure from surface and subsurface soil and debris (i.e., metal tubes) contaminated with Radium-226, Strontium-90, Bismuth-214, Niobium-94, Lead- 214, and Cesium-137 by human receptors, with consideration to current and reasonably anticipated future land uses. The radiological criterion for unrestricted release is a dose limit of 25 mrem/yr.

• Reduce the potential for migration of soil contaminated with Radium-226, Strontium-90, Bismuth-214, Niobium-94, Lead-214, and Cesium-137 to areas beyond the trenches (i.e., buffer zones surrounding the trenches, air, and groundwater).
