Rules & Planning

Overview


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

Rules


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 for a list of rules and ordinances, with links to each one.

Emissions Inventories


Emissions inventories are a comprehensive listing, by source, of air pollutant emissions. Emissions inventories cover point sources (large industries), area sources (numerous small sources, such as gas stations and consumer products usage), mobile sources (both on-road and off-road), and biogenic sources (gases released by plants and soil).

State Implementation Plans


The division also works with the Maricopa Association of Governments, the Arizona Department of Environmental Quality and the Arizona Department of Transportation to develop State Implementation Plans (SIP), policies/guidelines and reports required to complete SIP analyses. A SIP is a cumulative record of all air pollution control strategies, state statutes, state and local rules and local ordinances implemented by governmental agencies within Arizona.
