§923.45   Air and water pollution control requirements.

The program must incorporate, by reference or otherwise, all requirements established by the Federal Water Pollution Control Act, as amended (Clean Water Act or CWA), or the Clean Air Act, as amended (CAA), or established by the Federal Government or by any state or local government pursuant to such Acts. Such requirements must be the water pollution control and air pollution control requirements applicable to such program. Incorporation of the air and water quality requirements pursuant to the CWA and CAA should involve their consideration during program development, especially with respect to use determinations and designation of areas for special management. In addition, this incorporation will prove to be more meaningful if close coordination and working relationships between the State agency and the air and water quality agencies are developed and maintained throughout the program development process and after program approval.
