Rapid Response Notification System

As Maricopa County strives to meet the federal health limits for dust pollution, the awareness and actions of every individual can go a long way toward clean air. Failing to meet the federal health standard for dust [PM10] pollution threatens public health and ultimately more than $7 billion in transportation project funding for Maricopa County.

You can help to maintain compliance with air quality standards by signing up for notifications of Rapid Response events. When dust pollution levels begin to rise, the Maricopa County Air Quality Department will send you a message notifying you of where the pollution hot spot is and what steps you will need to do to help prevent an exceedance of the health standard.

How it works


When a Rapid Response notification is broadcast, the department will ask air quality permit holders with dust generating activities to inspect their site as soon as possible and employ Best Available Control Measures to stabilize all disturbed soils to reduce blowing dust.

Air Quality Department inspectors will canvass the area to ensure compliance with its dust control standards. If you see a dust control issue, give us a call and report the air quality violation at 602-372-2703 or file a report online.
