Fees: Permit fees apply

Thresholds: No difference from federal

Differences in regions: Maricopa, Pima, and Pinal counties, which have their own air pollution control agencies, have jurisdiction over stationary sources of air pollutants within their counties, except for refineries, copper smelters, coal-fired power plants, and Portland cement plants. These counties also have jurisdiction over portable sources of air pollutants that operate solely within their respective boundaries. Sources that will operate in multiple counties, or outside of the jurisdictions listed above, even for a short amount of time, must obtain permits from Arizona Department of Environmental Quality (ADEQ). Facilities located on Indian lands in Arizona are under the jurisdiction of federal EPA.
