PUBLIC NOTICE | Proposal to Renew Air Quality Dust Action General Permit for Maricopa County

ADEQ) has reached a preliminary determination and is proposing to renew the Air Quality Dust Action General Permit for Maricopa County. General Permits are a type of permit that applies to a class of sources; consequently, this revision may affect multiple sources throughout Maricopa County. This permit contains requirements from the Arizona Revised Statute 49-457.05, the Maricopa County Rule 310.01, and applicable regulations from Maricopa County Codes.

Information

Facilities permitted under the proposed Maricopa County Dust Action General Permit may emit particulate matter with aerodynamic diameter less than 10 microns (PM10). The Dust Action General Permit identifies a series of Best Management Practices (BMPs) for specific dust generating operations. When ADEQ’s Maricopa County Dust Control Forecast predicts that a day is at high risk for dust generation, dust generating operations that are not already required to control dust through a permit issued by ADEQ or the Maricopa County Air Quality Department are expected to choose and implement at least one BMP to reduce or prevent PM10 emissions.
