NOTE: In addition to the air quality control regions delineated here which form the geographic basis for the legal applicability of the regulations and air quality programs, there are administrative regions for all types of administrative actions (such as permit processing and responding to public inquires). This is done because it is necessary for administrative purposes that certain localities be in regions other than those listed above. This administrative delineation in no way alters the applicability of the regulations. Maps showing boundaries for both air quality control regions and administrative regions, and lists showing the assignment of localities for both, are available from the department upon request.
