Asbestos National Emission Standards for Hazardous Air Pollutants (NESHAP)

The Air Quality department regulates all asbestos renovation and demolition activity within Maricopa County. This covers all demolitions and regulated renovation activities containing friable asbestos-containing material greater than or equal to 160 square feet, 260 linear feet, or 35 cubic feet. This is determined by an Asbestos Hazard Emergency Response Act (AHERA) certified asbestos building inspector prior to demolition or renovation.

Asbestos NESHAP Notifications and Revisions

An Asbestos NESHAP Notification and Revision must now be submitted electronically through the Maricopa County Air Quality Department Online Portal. Instructions on how to do this can be found on our AQD Online Portal webpage. An Asbestos NESHAP Notification must be submitted at least 10 business days prior to starting any demolition or renovation activity, regardless if any asbestos is present. When submitting electronically, the 10-day waiting period begins immediately following an online submittal and payment.
