A release (leak) of approximately 19,000 gallons of gasoline occurred from the underground storage tanks at the Top Stop located at 15 South Main Street, Gunnison, Utah. The gasoline has contaminated soil and groundwater underlying parts of Gunnison. Because the contamination originated from their underground storage tanks, Top Stop is considered the responsible party, which means they are required to comply with State and Federal requirements for emergency response, investigation and cleanup.
Top Stop hired Wasatch Environmental Consultants to perform this emergency response, investigation and cleanup. The State of Utah, Division of Environmental Response and Remediation (DERR) provides regulatory oversight for cleanup of contamination from underground storage tanks. The DERR insures that the work conducted by Wasatch on behalf of Top Stop meets the requirements of both State and Federal Laws.
The gasoline contamination migrated (moved) underground to the southwest of the Top Stop station. The contamination appears to be following a depression in a hard pan layer that lies approximately 10-13 feet below the ground surface. (View a map of the impacted area). Impacts associated with the spill include gasoline vapors in businesses and residences. Vapor mitigation efforts are underway and have been successful in many of the impacted buildings. If you suspect vapors in your building or home, you may contact Lance Hess of Remedy, Inc. (801-361-9296) to conduct a vapor survey.
