Air Quality Compliance

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

Complaint Investigations

The division investigates over 1,000 complaints each year regarding air pollution concerns raised by residents of the 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.

Notice of Non-Compliance and Referrals

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 with a narrative description of the violation(s), and additional supporting evidence. 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. 


The division's enforcement team has the authority, per Arizona Revised Statutes, to recover penalties up to $10,000 per day, per violation.

Penalty Calculation


When calculating penalties, the enforcement team uses the Violation Penalty Policy. Appendix A to the Violation Penalty Policy was adopted in May 2012 and specifically addresses the calculation of penalties associated with asbestos violations (Rule 370).

The Violation Penalty Policy discusses the following issues: 
  • Degree to which the violator deviated from the substance and intent of the requirement
  • History of non-compliance
  • Level of risk the violation posed to the community and the environment
  • Size of the violator
  • Toxicity of the pollutant
