Air Quality Compliance and Enforcement

The Air Quality Compliance and Enforcement Division is responsible for ensuring that facilities are in compliance with applicable regulations and permit conditions.

Inspections and Compliance


The Air Quality Compliance and Enforcement Division annually conducts more than 10,000 inspections of various types, including construction sites and vacant lots for dust control, manufacturing facilities, fuel storage and distribution facilities, dry cleaners, vehicle refinishers and a host of other sources of air pollution.  In the event an inspector issues a notice of non-compliance, the inspection file is referred to the division’s enforcement team. Referrals will typically include photographs, the inspection report including a narrative description of the violation(s), and additional supporting evidence. 

The Maricopa County Air Quality Compliance and Enforcement Division is responsible for ensuring compliance with federal, state and county air pollution regulations. The enforcement activities of the department seek to deter future air quality violations and ensure a level the playing field among all regulated facilities so that none has a competitive advantage derived from non-compliance.   


Vapor Recovery Certifications


The Compliance and Enforcement Division issues several hundred vapor recovery certifications for gasoline tanker trucks and inspects hundreds of locations undergoing renovation or demolition where asbestos may be present.

Complaint Investigations


Additionally, the Compliance and Enforcement Division investigates over a thousand complaints each year regarding air pollution concerns raised by the residents of Maricopa County.

In the performance of their duties, division staff may initiate measures to control sources in violation of applicable regulations and permit conditions and begin the enforcement process by recommending legal action against potential violators.
