Who Regulates UST Systems?

In 1984, Congress directed the U.S. EPA to develop regulations for underground storage tank (UST) systems. EPA issued federal regulations, effective December 1988, that delegate UST regulatory authority to approved state programs. States are the primary implementers of the UST program and may have requirements more stringent than the federal regulations. As of September 2014, 38 states (plus the District of Columbia and Puerto Rico) have approved UST programs.

You should contact your state or local regulatory agency to learn about requirements that apply to your UST system. However, if your tanks are located in Indian Country, you should contact your EPA Regional UST Program Office.
