Air Quality Control Region (AQCR)

Definition - What does Air Quality Control Region (AQCR) mean?

An air quality control region is a federally designated area that is required to meet and maintain federal ambient air quality control standards. Regions may include nearby locations in the same state or nearby states that share common air pollution problems. The requirement for air quality control regions is a provision of the Clean Air Act of 1970.

Safeopedia explains Air Quality Control Region (AQCR)

Section 107 (a) of the Clean Air Act requires each state to assure air quality within the entire geographic area of that state by submitting an implementation plan that specifies the manner in which primary and secondary ambient air quality will be achieved and maintained within each air quality control region in that state. A district meeting a given standard is known as an 'attainment' area.
