Storm Water Management Plan

In 1972, the Federal Water Pollution Control Act (also referred to as the Clean Water Act (CWA) was amended to provide that the discharge of pollutants to waters of the United States from any point source is effectively prohibited unless the discharge is in compliance with an National Pollutant Discharge Elimination System (NPDES) permit.

The 1987 amendments to the CWA added Section 402 (p) that establishes a framework for regulating municipal and industrial storm water discharge under the NPDES Program. On November 16, 1990, the U.S. Environmental Protection Agency (U.S. EPA) published final regulations that establish application requirements for storm water permits.  The regulations require that storm water associated with industrial activity (storm water) that discharges either directly to surface waters or indirectly through municipal separate storm sewers must be regulated by an NPDES permit.
