Stormwater-Construction Activities
National Summary
When stormwater drains from a construction site, it carries sediment and other pollutants that harm lakes, streams, and wetlands. Controlling erosion from construction sites can significantly reduce the amount of sedimentation and other pollutants transported by stormwater runoff associated with construction activities. The U.S. Environmental Protection Agency (EPA) regulates stormwater discharges associated with construction activities through either the issuance of an individual permit or the Construction General Permit (CGP) in states where permitting authority has not been delegated. Most states are authorized to implement the stormwater NPDES permitting program.
