Facility Information

The City of Tucson applied for a renewal AZPDES permit for the discharge of pollutants to Waters of the U.S. from Tucson’s municipal separate storm sewer system (MS4). The existing permit was issued in 2011, expired 2016, but has been administratively continued pending reissuance of this permit. The permit requires the City to continue to implement and maintain a Stormwater Management Program to include control measures designed to reduce the discharge of pollutants to the maximum extent practicable. The permit establishes measurable goals to assess the efficacy of control measure design and implementation.
