National Pollutant Discharge Elimination System (NPDES)
City of Corona Storm Water and Urban Runoff Pollution Prevention Program
Unlike the sewer system, which carries water from your indoor drains to Storm Water System wastewater treatment plants, the storm drain system in Corona releases untreated water into flood control channels, creeks, the Santa Ana River, Prado Basin and ultimately the ocean.
Urban runoff contributes to the pollution found at local waterways. In Riverside County, Prado Basin, the Santa Ana River, Lake Elsinore, Canyon Lake, and Temescal Creek are just some examples of affected waterways.
To address this issue and comply with federal and state clean water legislation, the Santa Ana Regional Water Quality Control Board (SARWQCB) issues regulations specifying what can be discharged into storm drains.
Only Rain in the Storm Drain LogoThe City of Corona is listed as a co-permittee for the Riverside County NPDES Permit issued by the Santa Ana Regional Water Quality Control Board, and is bound to comply with all the aspects of the permit requirements. The City has adopted an ordinance that addresses non-storm water discharges that are not allowed into the City's storm water system. The State permit regulations and the City ordinance affect residential, industrial, commercial and construction sites and/or projects.
This web site was developed as a reference for those who have questions concerning our responsibility to keep the storm drains clean. The Storm Water Pollution Prevention Program (SWPPP) is comprised of three sections: Residential, Industrial/Commercial and New Development/Construction. Under each section basic information from everyday household activities to business owner activities and building contractor responsibilities is provided.
