Which federal agency oversees the UST regulations?

The Environmental Protection Agency (EPA) is the federal agency responsible for overseeing regulations related to underground storage tanks (USTs). The EPA established regulations under the Resource Conservation and Recovery Act (RCRA) to ensure the safe management and operation of USTs, which are primarily used to store petroleum products and other hazardous substances. The agency's focus includes preventing leaks and spills that could harm the environment and public health, and it sets standards for the installation, operation, maintenance, and closure of UST systems. The EPA works with state and local governments to enforce these regulations, providing guidance and support to ensure compliance and effective risk management.

Other agencies mentioned, such as the Department of Energy and the Occupational Safety and Health Administration, have different areas of focus and regulatory responsibilities that do not cover the aspects of UST management. The Department of Transportation primarily deals with the transportation of hazardous materials rather than storage issues.
