Non-Title V Permit Information

The Maricopa County Air Quality Department's (MCAQD) Non-Title V (NTV) Permitting program issues permits for sources such as gasoline plants, heating units and internal combustion engines and surface coating operations that are below the Title V emission thresholds and that are not considered exempt or insignificant per MCAQD Rule 200. The permits include conditions that regulate source-specific emission limits, monitoring, operational requirements, record keeping, and reporting.

A source may require Best Available Control Technology (BACT) analysis if it is new or requires modification to existing sources.

Synthetic Minor


The Air Quality Department's Non-Title V permitting program issues Synthetic Minor permits for sources with actual emissions of at least 50% of the major source emissions thresholds. The permits include conditions that regulate source specific emission limits, monitoring, operational requirements, record keeping and reporting.

General Permits


Some sources may qualify for a general permit rather than a Non-Title V permit. To find out if your operation qualifies for a general permit, visit the General Permit Information page or call 602-506-6010.
