The Clean Water Act authorizes EPA and states (delegated the authority by EPA), to regulate a variety of municipal and industrial operations, including treated wastewater, process water, cooling water and stormwater runoff from drainage systems that discharge pollutants into waters of the United States.
Stormwater runoff is generated from rain and snowmelt events that flow over land or impervious surfaces, such as paved streets, parking lots, building rooftops and does not soak into the ground. The runoff picks up pollutants like trash, chemicals, oils and dirt/sediment that can harm our rivers, streams, lakes and coastal waters. To protect these resources, communities, construction companies, industries, and others, use stormwater controls, known as best management practices (BMPs). These BMPs filter out pollutants and/or prevent pollution by controlling it at its source.
The NPDES stormwater program regulates some stormwater discharges from three potential sources: municipal separate storm sewer systems (MS4s), construction activities and industrial activities. Operators of these sources might be required to obtain an NPDES permit before they can discharge stormwater. This permitting mechanism is designed to prevent stormwater runoff from washing harmful pollutants into local surface waters.
Although the EPA remains the permitting authority in a few states, territories and on most land in Indian Country; most states are authorized to implement their own stormwater NPDES permitting program for Industrial and Construction sites.
