    The mission of the Department of Environmental Quality's Air Quality Program is to preserve and enhance Oregon's air quality to support healthy, clean air for all Oregonians. The Air Quality Program protects Oregon's air through program planning development and guidance, industrial source control, major new source review, coordination of permit and plan review programs, data analysis and reporting, and regulation.

    The program includes the Air Quality Division (headquarters), five Air Quality Sections in the regional divisions, and the Air Quality Monitoring Section at the Laboratory and Environmental Assessment Division.
