Rules and Planning

The Air Quality Department's Planning and Analysis Division is responsible for drafting and finalizing air pollution control rules and ordinances and for compiling emissions inventories.


Rules and ordinances are created and revised to comply with the Clean Air Act and to implement control strategies for stationary sources in Maricopa County. Visit our Adopted Rules page to view our rules and ordinances.

Emissions Inventories

Emissions inventories are a comprehensive listing, by source, of air pollutant emissions. Additional information about emission inventories are available on the Emissions Inventories page.

State Implementation Plans

A State Implementation Plan (SIP) is a cumulative record of all air pollution control strategies, state statues, state and local rules and local ordinances implemented by governmental agencies within Arizona. The division also works with the Maricopa Association of Governments, the Arizona Department of Environmental Quality and the Arizona Department of Transportation to develop the Maricopa County portion of the Arizona SIP.
