Spill Description:
On 3/10/2025, Bashor PC AA 9-14 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 4/29/2025 indicate that soil sample, PWV01-S, discovered beneath the produced water vessel, exceeded ECMC Table 915 standards for 1-methylnaphthalene at 0.0392 mg/kg, and 2-methylnaphthalene at 0.0393 mg/kg. Groundwater was not encountered during decommissioning activities. This location is within the Pronghorn Winter Concentration High Priority Habitat.
