Spill Description:
On 6/3/2025, the potential presence of impacted material(s) was identified via hydrocarbon odor, and hydrocarbon staining during decommissioning activities at the Edens 11, 12, 18-52, tank battery, sample: PWV01-N & PWV01-W, located at the produced water vessel in the same excavation. The volume of potentially impacted material(s) is not currently known. Out of an abundance of caution, the operator is submitting notification within 24 hours of the discovery of the potential presence of impacted material(s) soil. Initial soil sampling is underway to determine whether any constituents are present at levels in excess of Table 915-1 standards. Groundwater was not encountered during decommissioning activities. This location is within the Mule Deer Severe Winter Range and Pronghorn Winter Concentration. Final analytical results from initial soil sampling will be included on a Supplemental Form 19.
