The U.S. Environmental Protection Agency (EPA) released regulations for USTs in 2015 that aimed to curb releases of petroleum and hazardous substances into the environment by focusing on ensuring proper operation and maintenance (O&M) of UST equipment and emphasizing the importance of operator training.

Federally regulated facilities were required to comply with the revised rules by October 13, 2018. The states and territories with EPA-approved UST programs were required to adopt the revised regulations and reapply for state program approval by October 13, 2018. Consequently, the majority of UST owners and operators must comply with the EPA’s O&M rules. This resource center guides you through these extensive requirements.
