The Air Quality Department regulates all asbestos renovation and demolition within Maricopa County under the National Emission Standards for Hazardous Air Pollutants (NESHAP). Anyone performing demolition and/or renovation activities within the county must have the facility inspected and file a notification with the department prior to the demolition or renovation activity beginning. See the Asbestos section for more information.
Wood burning is regulated when pollution levels rise because the process of burning wood can produce fine particulate matter that can be harmful to your lungs. Visit our Burning page for more information on how to obtain a burn permit, burning activities, and to learn about our Burn Cleaner, Burn Better campaign.
Dust Control Permit Applications
The department issues dust control (or earthmoving) permits when earthmoving operations disturb an area greater than one tenth of an acre of land (0.1 acre or 4,356 square feet). Earthmoving operations are activities that use any equipment that may generate fugitive dust. Some examples include blasting, cutting and filling, demolition, drilling, excavating, grading, leveling, trenching, and weed abatement by discing or blading. To obtain applications, visit our Forms and Applications page and select Dust Control.

General Permits are an alternative to regular permits and simplify the process for authorizing operation.
Non-Title V Permits
Non-Title V Permits are for regulated sources, such as graphic arts or surface coating operations, that are below Title V emission thresholds.
Performance tests are conducted according to established procedures in order to quantify emissions and provide an objective means for determining compliance with established emission limits. See our Performance Testing page for more information.
