| On 5/23/2025, Bernhardt State 24-36 wellhead decommissioning activities were completed. During the completion of the activities, potential presence of impacted material(s) was not 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 6/11/2025 indicate that soil sample, WH01@6, discovered at the wellhead, exceeded ECMC Table 915 standards for naphthalene at 0.018 mg/kg, TPH at 577.335 mg/kg, benzo(a)anthracene at 0.013, 1-methylnaphthalene at 0.116 mg/kg, and 2-methylnaphthalene at 0.195 mg/kg. Groundwater was not encountered during decommissioning activities. This location is within the Mule Deer Severe Winter Range and is within 300 feet of surface waters of the state. |
