CLEAN AIR ACT (1970)
The Clean Air Act is the comprehensive Federal law that regulates air emissions from area,
stationary, and mobile sources.
This law authorizes the U.S. Environmental Protection Agency to establish
National Ambient Air Quality Standards (NAAQS) to protect public health and the environment.
The goal of the Act was to set and achieve NAAQS in every state by 1975.
The setting of maximum pollutant standards was coupled with directing the
states to develop state implementation plans (SIP's) applicable to appropriate industrial sources in the state.
