NPDES / STORMWATER
Stormwater Utility Feasibility Study
National Pollutant Discharge Elimination System
The goal of the federally mandated National Pollution Discharge Elimination System (NPDES) Phase II program is to preserve, protect and improve the Nation’s water resources from polluted stormwater runoff. NPDES Phase II is intended to reduce adverse impacts to water quality and aquatic habitat by instituting the use of controls on the unregulated sources of stormwater discharges that have the greatest likelihood of causing continued environmental degradation. NPDES Phase II requires operators of Municipal Separate Storm Sewer Systems (MS4s) in urbanized areas to implement Best Management Practices (BMPs) defined in six minimum control measures to control polluted stormwater runoff.
