Indian Tribes: Air Quality Planning and Management

The Clean Air Act (CAA) directs EPA to promulgate regulations specifying those provisions of the Act for which it is appropriate to treat Indian tribes in the same manner as states. For those provisions specified, a tribe may develop and implement one or more of its own air quality programs under the Act. This final rule sets forth the CAA provisions for which it is appropriate to treat Indian tribes in the same manner as states, establishes the requirements that Indian tribes must meet if they choose to seek such treatment, and provides for awards of federal financial assistance to tribes to address air quality problems.
