State-by-State Guide to UST Regulations

The U.S. Environmental Protection Agency introduced new federal underground storage tank regulations in 2015, with compliance deadlines that began in 2018. To help operators understand what is expected of them, Source has compiled a comprehensive state-by-state guide to UST regulations. Click on a state in the map to review your state’s regulations.

Many states operate under a “State Program Approval” (SPA) designation that enables them to act as the regulatory authority in lieu of the federal program, as long as the state regulations meet or exceed the federal regulations. UST operators in states without approved programs must meet federal AND state requirements.

Source will continue to collect and update our information about UST regulations. If you observe inaccurate information or have updated information to share, please contact Source.
