Spill Description:
On 6/19/2025, Edens 18-52 flowline 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. Partial laboratory analytical results received on 6/20/2025 indicate that soil samples, FL01-08, discovered along the flowline, exceeded ECMC Table 915 standards for 1,2,4-trimethylbenzene at 0.14 mg/kg, 1,3,5-trimethylbenzene at 0.035 mg/kg, and naphthalene at 0.064 mg/kg. Groundwater was not encountered during decommissioning activities. This location is within the Mule Deer Severe Winter Range and Pronghorn Winter Concentration high priority habitat.
