Which regulatory agency is primarily responsible for enforcing the Clean Water Act?

The Environmental Protection Agency (EPA) is primarily responsible for enforcing the Clean Water Act. This agency plays a critical role in regulating the discharge of pollutants into the waters of the United States, establishing water quality standards, and ensuring compliance with the law. The Clean Water Act aims to restore and maintain the integrity of the nation's waters, and the EPA's enforcement capabilities are essential for this mission. The agency not only develops regulations but also works with state and tribal governments to implement programs that ensure clean water. This regulatory framework includes issuing permits for discharges, monitoring water quality, and guiding the enforcement of penalties against violators, all of which are central to the objectives of the Clean Water Act.
