Title V Permit Information


Title V is a federal program designed to standardize air quality permits and the permitting process for major sources of emissions across the country. Title V of the 1990 federal Clean Air Act Amendments required the Environmental Protection Agency (EPA) to establish a national operating permit program, and required states and local permitting authorities to develop and submit a federally enforceable operating permit program for EPA approval.

Air Quality Agencies issue comprehensive operating permits to facilities that emit significant amounts of air pollutants. For all implementing agencies in the country, there are standard requirements for permit programs and permit content. The following is a comprehensive list of Title V facilities in Maricopa County.
