The Clean Water Act (CWA) was enacted into law in 1972 to restore and maintain clean and healthy waters. In 1987, the CWA was amended to regulate the discharges of untreated wastewater to rivers, lakes, and streams which is known as point source pollution from municipalities, industries, construction activities, and businesses.
The National Pollutant Discharge Elimination System (NEPDES) permitting program was regulated by the United States Environmental Protection Agency (USEPA). In 1987, the State of Utah was granted primacy of the NPDES program known as the Utah Pollutant Discharge Elimination System (UPDES), the intent of the storm water permits program is to reduce the amount of pollutants from entering into rivers, lakes, and streams.

Specifically, in Utah considering the rules, regulations, and maintenance of stormwater management, The Salt Lake County Stormwater Coalition was established to help municipalities execute the requirements.
