17.04.020   Purpose.
   A.   The purpose of this title is to prevent and to reduce air pollution originating in Pima County, so as to restore and preserve the quality of the outdoor air in all areas of Pima County to which the general public has access.
   B.   This title is specifically intended to progressively reduce the levels of air pollutants in areas which exceed one or more health-related or welfare-related standard, and to prevent the levels of air pollutants from exceeding analogous standards where the air is already clean. Therefore, the air quality control officer shall periodically evaluate progress made toward these goals and he shall within sixty days of such time as information becomes available to him that the air quality in any area of the county which already exceeds a health-related or welfare-related standard is further deteriorating, or within sixty days of learning that any maximum allowable incremental increase in air pollutants set forth herein to preserve the air quality of the county is being exceeded, review the adequacy of this title and propose to the environmental quality advisory council and board of supervisors appropriate revisions or additions to correct any deficiencies. Furthermore, the control officer shall prepare and make available to the general public an annual report describing such progress.
