Permittee:
ADOT
Facility:
ADOT Phase I Municipal Separate Storm Sewer System
Arizona
ADOT applied for a renewal AZPDES permit for the proposed discharge of pollutants to Waters of the United States from the ADOT Phase I Municipal Separate Storm Sewer System in Arizona. The system is a publicly owned system of conveyances that collects and conveys stormwater and discharges directly to waters of the United States. The permit requires ADOT to continue to implement and maintain a Stormwater Management Program designed to reduce the discharge of pollutants to the maximum extent practicable. The permit establishes measurable criteria to assess the efficacy of control measure design and implementation.
