Northrop Grumman System Corp • 5000 South 8400 West WVC, UT 84120 • (801) 251-3098 September 25, 2023 Mr. Doug Hansen, Director Utah Department of Environmental Quality Division of Waste Management and Radiation Control P.O. Box 144880 Salt Lake City, UT 84114-4880 Re: RCRA Facility Investigation Closure Letter SWMU S-25 Site ATK Launch Systems LLC. - Bacchus UTD001705029 Dear Mr. Hansen: In July 2022 a Resource Conservation and Recovery Act (RCRA) Facilities Investigation Report (RFI) was submitted to the Division of Waste Management and Radiation Control (the Division) for Solid Waste Management Units (SWMU) Sump 25 (S-25). This RFI found that the following constituents of potential concern (COPC) were above the residential Regional Screening Levels (RSLs) including metals, semi-volatile organic compounds (SVOCs), volatile organic compounds (VOCs): Arsenic, Benzo(a)pyrene, Dibenzo(a, h)anthracene, and 2-Nitropropane. All these detections and additional detections of SVOCs and VOCs below the RSLs were in the top approximately 18-inches of clay liner. Pyrene was the only SVOC detected below the clay liner. No VOCs were detected below the clay liner. The maximum arsenic concentration below the clay liner was 12.6 mg/kg. The arsenic concentration is above the RSL of 0.68 mg/kg. However, the background threshold value according to the Evaluation of Background Soils for Metals and Dioxin at the Bacchus Facility submitted April 2014 is 9.98 mg/kg. This evaluation had detections of arsenic as high as 17.6 mg/kg. Additionally, the Division’s Technical Guide for Risk Assessments: Utah Administrative Code R315-101 (TGRA) Table 2 has a BVT for arsenic of 27.0 mg/kg. Due to the elevated concentrations of the above COPC, the July 2022 RFI submitted to the Division stating that ATK will excavate the clay liner and haul the waste to a State approved waste facility. August of 2023 ATK contracted with Flare Construction to remove 23 tons of the clay liner, approximately 16 cubic yards and hauled the liner to Clean Harbors Grassy Mountain Facility. After removal, samples were collected near the floor of the excavation along each of the corners. The following SVOCs were detected in the soils below the clay liner after remediation: chrysene, fluoranthene, and pyrene. Chrysene was detected in one location with a concentration of 0.25 mg/kg. The RSL for chrysene is 110 mg/kg and the dilution attenuation factor (DAF) groundwater RSL is 9.1 mg/kg. Therefore, chrysene is at acceptable concentrations. Fluoranthene was detected at two locations with concentrations of 0.13 and 0.22 mg/kg. The RSL for fluoranthene is 2,400 mg/kg and the DAF DSHW-2023-209660 Mr. Doug Hansen, Director Utah Department of Environmental Quality Division of Waste Management and Radiation Control 2 | P a g e Northrop Grumman Systems Corp • 5000 South 8400 West WVC, UT 84120 • (801) 251-3098 groundwater RSL is 89 mg/kg. Therefore, fluoranthene is at acceptable concentrations. Pyrene was detected in one location with a concentration of 0.20 mg/kg. The RSL for pyrene is 1,800 mg/kg and the DAF groundwater RSL is 13 mg/kg. Therefore, pyrene is at acceptable concentrations. The University of Tennessee and Oak Ridge National Laboratories Risk Assessment Information System (RAIS) was used to create a total risk for the maximum detections for COPCs. An acceptable cancer risk is less than 1.0E-06 and an acceptable health risk is less than 1.0. According to the attached RAIS spreadsheet the cancer risk at the site is 4.03E-07 and the health risk is 5.45E- 02, both an order of magnitude below the acceptable risk. As the confirmation samples total risk were an order of magnitude below acceptable levels and COPCs were several orders of magnitude below RSLs, ATK petitions the Division for a closure of SWMU S-25 with a “No Further Action”. Please, feel free to contact Tim Jimenez with any questions at 801-251-2142 or timothy.jimenez@ngc.com. Sincerely, Kris H. Blauer Manager, Environmental Services cc: D.
