High-Pollution Advisory (HPA) Notification
In Area A during days when HPAs have been called for particulate matter, it is illegal to use an off-highway vehicle (including an all-terrain vehicle or an off-road recreation motor vehicle) on an unpaved surface that is not a public or private road, street, or easement—except at designated locations and events where dust controls are in place.
ADEQ is now offering a text-messaging service to inform people when an HPA is being issued for the Greater Phoenix Area. If you sign up for this service, you will receive a text message on your cell phone or small-message service (SMS) wireless device by mid-afternoon on the day before the HPA is issued.
While ADEQ charges no fee for this service, the fees set under your cell phone or wireless device plan will apply.
