Title V permits, also called Operating Permits, are required under the Clean Air Act and are issued to all major sources of air pollution and to a limited number of smaller sources.

Fees: Permit fees apply
Thresholds: Same as federal statewide. May be more stringent in regions.
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 powerplants, 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.
