Why do I need an Arizona Pollutant Discharge Elimination System (AZPDES) Individual Permit?

This permit is for municipal, domestic and non-domestic (industrial) discharges of pollutants to a surface water that fits the definition of “waters of the U.S.” as described in the Clean Water Act. The permit is valid for five years. A renewal permit can be continued past five years if a renewal application is received 180 days prior to the expiration date of the permit.

To download an application for this permit, see the "Forms" section located on the right side bar of this page.
