Spill Description:
On 6/3/2025, Edens 11, 12, 18-52 tank battery decommissioning activities were completed. During the completion of the activities, no potential presence of impacted material(s) was observed/smelled. Consistent with Rule 912, samples were collected and analyzed to determine whether any constituents are present at levels in excess of Table 915-1 standards. Final laboratory analytical results received on 6/17/2025 indicate that soil samples, SEP01-FL and SEP01-DL, discovered at the separator, exceeded ECMC Table 915 standards for benzene at 0.0032 mg/kg, and TPH at 1,000 mg/kg. Groundwater was not encountered during decommissioning activities. This site is in the following High Priority Habitats: Mule Deer Severe Winter Range, and Pronghorn Winter Concentration.
