How does the CWA work?
The formal mechanism for implementing the CWA is the permitting system known as the National Pollutant Discharge Elimination System (NPDES) permit. NPDES permits are required for all dischargers to U.S. waters. The City s Water Reclamation Facility is issued a permit with specific requirements that protect San Luis Obispo Creek. Maximum fines for violating the permit can range from $25,000 to $1,000,000/day.
