The mission of the U.S. Environmental Protection Agency (EPA) is to protect human health and the environment. The EPA has Congressional authority to enforce the major federal environmental regulations: the Clean Water Act (CWA), the Clean Air Act (CAA), and the Resource Conservation and Recovery Act (RCRA).
