The Maricopa County Air Quality Department's enforcement division is responsible for settling air
quality violations within Maricopa County. Enforcement action taken on local companies violating
clean air rules will be published and updated on a monthly basis.
The ‘Notes’ column in the Enforcement Reports below indicates the county air pollution
rule/section, permit condition or federal regulation for which the violator was cited. Details of
county rule numbers may be found on our
Adopted Rules page.
An Order of Abatement by Consent [OAC] is defined as any agreement to resolve alleged violations
entered into by the department which is done under the authority of A.R.S. 49-511E. By signing an
OAC, recipients of a Notice of Violation [NOV] from this department agree to settle violations with
the county without admitting to the violations.
Additional information regarding these Enforcement Reports may be obtained through the Maricopa County
Air Quality Department's Records division. For details on how to submit a public records request, please
