The Riverside County Transportation Department complies with the National Pollutant Discharge Elimination System that is also known as NPDES. There are three (3) Regional Boards in Riverside County: the Santa Ana, San Diego, and Colorado River Regional Water Quality Control Boards. Each jurisdiction imposes regulations and permit requirements that regulate water quality in Riverside County.
