| On 3/10/2025, Bashor 9-42 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. Final laboratory analytical results received on 5/1/2025 indicate that soil samples, FL01R-W, discovered at the wellhead flowline riser, exceeded ECMC Table 915 standards for benzo(a)anthracene at 0.0953 mg/kg, and 1-methylnaphthalene at 0.00725 mg/kg. Groundwater was not encountered during flowline decommissioning activities. this location is within the following high priority habitats: Pronghorn Winter Concentration, Mule Deer Winter Concentration Area, and Mule Deer Severe Winter Range. |
