Rapid Response Notification System
As the region of 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 notification of a Rapid
Response event. 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.
A Rapid Response notification will be sent from one of the following 16 air monitoring locations.
