Non-Title V Permit Info
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, recordkeeping and reporting. A source may
trigger BACT at which the Best Available Control
Technology [BACT] analysis will be required.
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, recordkeeping and reporting.
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,
see the general permit page or call (602) 506-6010.
