Shelley Executive Director DIVISION OF ENVIRONMENTAL RESPONSE AND REMEDIATION Brent H. Everett Director ERRL-0367-24 August 28, 2024 CERTIFIED MAIL RETURN RECEIPT REQUESTED Craig Larson Wind River Petroleum 5097 South 900 East Salt Lake City, Utah 84117 Re:Corrective Action Plan Approval Former C-4 Top Stop, located at 15 South Main Street, Gunnison, Utah Facility Identification No. 2000220, Release Site MHB Dear Mr. Larson: The Division of Environmental Response and Remediation (DERR) has completed its review of the Corrective Action Plan (CAP) prepared by Wasatch Environmental, Inc., submitted to us on May 8, 2024, for the above-referenced facility. The CAP is in general compliance with Utah Admin. Code R311-211 and R311-202. The DERR makes no guarantee, implied or otherwise, that the approved CAP will be successful in obtaining established cleanup levels. In the event that the CAP does not meet the cleanup goals, further work at the facility may be required prior to site closure consideration. The public notification process has been completed and there was no substantial public interest or other reason to warrant a public meeting prior to CAP approval or implementation of the cleanup activities. The CAP is approved and will inject PetroFix EA BlendTM into injection boring near MW-27 and MW-41. The projected start date in the public notification is November 30, 2024. If this schedule has changed, please contact your project manager with an updated implementation schedule. Any modifications to the above CAP/conditions must be reviewed and approved by the Division Director prior to their implementation. The local health department must be notified 72 hours before beginning corrective action activities. Facility ID# 2000220 Page 2 Cleanup levels for this release have been established as ISLs using criteria outlined in Utah Admin. Code R311-211. Considering the current land use, these levels are expected to protect all receptors within a critical distance at the site. It may be necessary to reevaluate the cleanup levels if additional information becomes available or if the land use changes in the future. The CAP construction or implementation should begin within 90 days of receiving this approval letter. If corrective action has not begun by November 30, 2024, a revised CAP must be submitted for approval. Please submit a corrective action report detailing the cleanup activities and any sample results within 60 days after the corrective action is complete. Once it has been adequately demonstrated that contaminant concentrations are below the established cleanup levels, you may petition the DERR for site closure. After reviewing this information, the DERR will determine if no further action is warranted or if additional work is needed. If you have any questions or concerns, please contact Liberty Coe, the DERR project manager, at (801) 536 4100. Sincerely, Brent H.
