Which agency is responsible for enforcing the Clean Water Act?

The Environmental Protection Agency (EPA) is the agency responsible for enforcing the Clean Water Act, which aims to restore and maintain the integrity of the nation's waters. Established in 1970, the EPA develops and enforces regulations to ensure that water quality standards are met, manages permits for discharges into waterways, and oversees state programs that work toward clean water goals.

The Clean Water Act is a key piece of legislation aimed at preventing water pollution, and the EPA plays a crucial role in implementing and enforcing its provisions. This includes monitoring water quality, regulating pollutants, and working with states and local agencies to promote pollution control efforts. The agency's expertise and authority in environmental matters position it effectively to handle enforcement of water-related regulations, making it the correct choice for this question. Other options represent agencies focused on different areas, such as occupational safety or education, and therefore do not have jurisdiction over the Clean Water Act.
