Incident Events

Date	Detail
12/11/2025	90-day time extension request is approved. Remediation Due date updated to March 16, 2026. Email submitted on 12/09/2025 via third party states, “On behalf of Hilcorp Energy Company, Ensolum respectfully requests a 90-day extension to the December 14, 2025, reporting deadline for the SAN JUAN 29-7 #563S (30-039-27428) release. Delineation activities are complete, and the majority of impacted soil has been excavated. During remediation, two previously permitted BGTs were found to be situated within a FEMA 100-year floodplain, an issue not accurately reflected on the original BGT permit. To maintain compliance, Hilcorp elected to close and remove both tanks prior to completing the remaining excavation. The BGT closures were recently completed, and the area is now accessible for the final removal of minor residual impacts. Hilcorp is currently scheduling a crew to complete this excavation, collect confirmation samples, and allow Ensolum to prepare the Closure Request. To accommodate contractor scheduling, laboratory turnaround, and preparation of the final report, Hilcorp requests a 90-day extension, extending the deadline to March 14, 2026".
