NPDES Stormwater Permit Program in New England

Related Information

  • Industrial Activities
  • Construction Activities

The Clean Water Act authorizes EPA and states, which are delegated the authority by EPA, to regulate point sources that discharge pollutants into waters of the United States through the National Pollutant Discharge Elimination System (NPDES) permit program. So-called "point sources" are generated from a variety of municipal and industrial operations, including treated wastewater, process water, cooling water, and stormwater runoff from drainage systems. The NPDES Stormwater Program (national EPA NPDES site), in place since 1990, regulates discharges from municipal separate storm sewer systems (MS4s), construction activities, industrial activities, and those designated by EPA due to water quality impacts.

Residual Designations

The Clean Water Act (CWA) and related regulations define the specific industrial and municipal stormwater sources that must be authorized by an NPDES permit. The CWA recognizes that other sources, such as commercial properties, may need to be regulated on a case-by-case or category-by-category basis based on additional information or localized conditions. The authority to regulate other sources based on the localized adverse impact of stormwater on water quality through NPDES permits is commonly referred to as the "Residual Designation" authority.
