| On 4/10/2024, KOHLHOFF USX AB 17-01P 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 May 21, 2024, indicate the soil sample, FL-SS-08, discovered at the former flowline exceeded ECMC Table 915 standards for Benzo(a)anthracene at 0.012 mg/kg. Groundwater was not encountered during site investigation activities. This location is within the Pronghorn Winter Concentration High Priority Habitat.
A reissuance of the original unaltered copy of the attached lab report, which were generated by the lab to protect the laboratory analytical report from subsequent modification by anyone outside the lab (Reissued Report) is attached to this package. |
