In July 2015, EPA revised the federal UST regulation. This was the first major revision to the UST regulation since 1988. The revision strengthened the 1988 UST regulation by increasing emphasis on properly operating and maintaining UST equipment. To ensure our compliance performance measures reflect the 2015 UST regulation, EPA and the Association of State and Territorial Solid Waste Management Officials coordinated to update our existing compliance performance measures and add new measures. We did not change the corrective action performance measures; they remain the same. These updates supersede the Significant Operational Compliance (SOC) measures. States will not begin reporting on the updated and new compliance measures, however, until they have fully implemented their revised UST regulations.You may need a PDF reader to view some of the files on this page.
