40 CFR § 1.3 - Purpose and functions.
The U.S. Environmental Protection Agency permits coordinated and effective governmental action to assure the protection of the environment by abating and controlling pollution on a systematic basis. Reorganization Plan 3 of 1970 transferred to EPA a variety of research, monitoring, standard setting, and enforcement activities related to pollution abatement and control to provide for the treatment of the environment as a single interrelated system. Complementary to these activities are the Agency's coordination and support of research and antipollution activities carried out by State and local governments, private and public groups, individuals, and educational institutions. EPA reinforces efforts among other Federal agencies with respect to the impact of their operations on the environment.
