What is being done to protect air quality in wilderness?

The Clean Air Act requires that Federal land managers review new source permit applications that would affect Class I areas, which include 88 National Forest wildernesses and 48 National Parks designated between 1964 and 1977. The emerging air resource management programs involve wilderness managers who must decide which resources are to be protected in wilderness, and air quality specialists who will inventory and monitor air quality-related values in Class I areas, review Prevention of Significant Deterioration permit applications, provide recommendations to regulating agencies, and coordinate with air regulatory agencies and other federal and state land management agencies. Wildernesses designated after 1977 are Class II areas.
