What is the role of the EPA in relation to USTs?

The Environmental Protection Agency (EPA) plays a crucial role in the oversight of Underground Storage Tanks (USTs) to ensure safety and environmental protection. Specifically, the EPA's responsibilities include enforcing safety standards that minimize the risks associated with USTs, such as leaks or spills that can contaminate soil, groundwater, and surface water. By establishing regulatory frameworks, the EPA makes certain that tank owners and operators implement measures to prevent contamination, conduct regular inspections, and report any incidents of leaks or failures.

Additionally, the agency provides guidance and resources to help states implement UST programs effectively, ensuring consistency and adherence to standards that protect public health and the environment. The focus on preventing environmental contamination underscores the importance of the EPA's role in regulating the usage and management of USTs effectively. This is why the correct answer highlights the agency's enforcement of safety standards and its overarching goal of environmental protection.
