| On 8/25/2025, Girvan 22-10 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 9/17/2025, indicate the soil sample, SEP01-FLR-B, discovered at the separator flowline riser exceeded ECMC Table 915 standards for 1,2,4-trimethylbenzene at 0.010 mg/kg, naphthalene at 0.006 mg/kg, 1-methylnaphthalene at 0.027 mg/kg and 2-methylnaphthalene at 0.057 mg/kg. Groundwater was not encountered during site investigation activities. This location is within the Mule Deer Severe Winter Range High Priority Habitat.
