The Utah Pollutant Discharge Elimination System (UPDES) is the Utah version of the National Pollutant Discharge Elimination System (NPDES), which is the permit system mandated by § 402 of the Clean Water Act to control pollutants in waters of the U.S., including storm water. The Utah Storm Water Program is part of the UPDES Program. The Storm Water Program regulates storm water discharges from three potential sources:
Operators of these sources may be required to obtain a Utah Pollutant Discharge Elimination System (UPDES) Storm Water permit before they can discharge. The purpose of the permit is to prevent storm water runoff from washing harmful pollutants into local surface waters such as streams, rivers, or lakes.
Utah Storm Water Advisory Committee (USWAC)
The Utah Storm Water Advisory Committee (USWAC) was formed on December 9, 2003. The Committee Serves as an agent to address a variety of storm water issues statewide, including Phase I and Phase II Implementation, Underground Injection Wells for Storm Water, SW Treatment Design Criteria, and Storm Water Education.
2022 Committee Chair

The Utah Storm Water Advisory Committee will coordinate their efforts to reduce storm water pollution and provide adequate flood control. The committee will evaluate and define governing regulations, disseminate information, promote efficient training, and assist local municipalities and other interested parties to implement best management practices that are consistent with their individual needs and resources. The committee will also support efforts of State and federal agencies to implement necessary storm water regulations that are economically feasible.
