ADEQ is considering closure of the following leaking underground storage tank (UST) case:

Leaking UST Case File No.: 4367.01-.04
Facility ID No.: 0-005032
Navajo County

Facility address: 
Thompson's Muffler
404 West Hopi Drive
Holbrook, Arizona 86025

Arizona regulations¹ allow case closure on leaking UST sites with groundwater contamination at levels above the Arizona Aquifer Water Quality Standards (AWQS) or Tier 1 Corrective Action Standards if it can be demonstrated that there is no exposure risk to public health and any remaining contamination is attenuating.  ADEQ evaluated site specific conditions and analytical data provided for this site. Based on this review, ADEQ has determined that the case meets the regulatory requirements for closure.
