Safeopedia Explains Clean Water Act (CWA)
The CWA made it unlawful to discharge any pollutant from a point source into "navigable waters," unless a permit was obtained. EPA's National Pollutant Discharge Elimination System (NPDES) permit program controls discharges. Point sources are discrete conveyances such as pipes or man-made ditches. Individual homes that are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit; however, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters. The EPA has recently clarified for the businesses of today that "navigable waters" may include near anything wet and this will be an area to watch for small businesses.
