About the National Pollutant Discharge Elimination System (NPDES)
The NPDES permit program, created in 1972 by the Clean Water Act (CWA), helps address water pollution by regulating point sources that discharge pollutants to waters of the United States. The permit provides two levels of control: technology-based limits and water quality-based limits (if technology-based limits are not sufficient to provide protection of the water body).
Under the CWA, EPA authorizes the NPDES permit program to state, tribal, and territorial governments, enabling them to perform many of the permitting, administrative, and enforcement aspects of the NPDES program. In states authorized to implement CWA programs, EPA retains oversight responsibilities. Currently 46 states and one territory are authorized to implement the NPDES program.

Storm water is the runoff from precipitation (rain or snow melt) that is not absorbed into the ground and flows over land surfaces entering our lakes and streams. As the water travels across land it collects debris, sediment, yard waste, engine oils, lawn fertilizers, herbicides, and other pollutants that negatively impact our lakes, streams and drinking water.
The City has put together and is implementing a Storm Water Management Plan. The Plan aims to educate and involve the community, provide guidelines and requirements to minimize pollutants caused by construction activities, improve and maintain current storm drain infrastructure, and minimize illicit discharges into the storm drain system.
About the Utah Pollutant Discharge Elimination System (UPDES)
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.
