Regional Air Quality Planning

Regional Air Quality Planning



MAG was designated by the Governor of Arizona in 1978 and recertified by the Arizona Legislature in 1992 to serve as the regional air quality planning agency for the Maricopa County nonattainment area. In this role, MAG develops regional air quality plans to address air pollution problems. In June 2016, the Governor certified MAG as the lead planning organization for the Pinal County PM-10 and PM-2.5 nonattainment areas. MAG will develop air quality plans for these areas in cooperation with the Sun Corridor Metropolitan Planning Organization. MAG also conducts the air quality conformity analyses for transportation programs. MAG plans to make sure that these transportation activities do not cause air quality violations.
