Which federal agency is responsible for regulating underground storage tanks (USTs) in the U.S.?

The Environmental Protection Agency (EPA) is the federal agency responsible for regulating underground storage tanks (USTs) in the United States. The EPA established regulations to protect human health and the environment from the potential hazards posed by these tanks, especially those containing hazardous substances and petroleum products.

The regulation of USTs by the EPA focuses on preventing leaks, which can contaminate soil and groundwater, posing significant environmental risks. To this end, the agency sets standards for the design, construction, installation, and maintenance of UST systems, ensuring they meet safety and environmental protection requirements.

In addition to regulating USTs, the EPA provides guidance and oversight to states on implementing their UST programs, thereby fostering a consistent approach to managing and monitoring these storage facilities across the country. The agency also addresses issues related to leak detection, operator training, and spill response, all crucial for the proper management of underground storage tanks.
