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.
After an inspector has issued a Notice of Violation (NOV), the Compliance and Enforcement Division refers an
inspection file to the division’s enforcement team. Referrals will typically include photographs, the inspector's report including a narrative description of the violation(s),
and additional supporting evidence.
For compliance-related links, please see More Information.
When calculating penalties, the Enforcement Division uses the Violation Penalty Policy and considers the following:
Level of risk the violation posed to the community AND the environment
Toxicity of the pollutant
History of non-compliance
Size of the violator
Degree to which the violator deviated from the substance and intent of the requirement
The Enforcement Division has the authority, per Arizona Revised Statutes, to recover penalties up to $10,000 per day, per violation.
Enforcement cases are published on the website on a monthly basis and will be updated by the 15th of each month.
