Stormwater Program

City of Hemet Stormwater Program

The City of Hemet proudly joins Riverside County Watershed Protection in a partnership between Riverside County, the Flood Control & Water Conservation District, Coachella Valley Water District and 27 cities to manage watershed program focused on sustaining our natural resources. This partnership emphasizes public education, best management practices, evaluation, and monitoring our waterways to prevent stormwater pollution and comply with all federal, state, and local regulations.

On January 29, 2010 the Santa Ana Regional Water Quality Control Board issued a fourth-term area wide National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System Permit (MS4 Permit) to the Riverside County Flood Control and Water Conservation District (the Principal Permittee), the County of Riverside and the Cities of Beaumont, Calimesa, Canyon Lake, Corona, Hemet, Lake Elsinore, Moreno Valley, Menifee, Norco, Perris, Riverside, San Jacinto and Wildomar (Permittees). The Santa Ana MS4 Permit is for the portion of the Santa Ana River watershed located within Riverside County (Order Number R8-2010-0033, NPDES Permit Number CAS618033) (PDF). The Permittees' stormwater programs are designed to ensure compliance with this permit. On June 7, 2013 the Santa Ana Regional Water Quality Control Board amended the permit (Order Number R8-2013-0024) (PDF) to include the Cities of Eastvale and Jurupa Valley.

What is an NPDES permit?

The Clean Water Act prohibits anybody from discharging "pollutants" through a "point source" into a "water of the United States" unless they have an NPDES permit. The permit will contain limits on what you can discharge, monitoring and reporting requirements, and other provisions to ensure that the discharge does not hurt water quality or people's health. In essence, the permit translates general requirements of the Clean Water Act into specific provisions tailored to the operations of each person discharging pollutants.

Do I need an NPDES permit?

It depends on where you send your pollutants. If you discharge from a point source into the waters of the United States, you need an NPDES permit. If you discharge pollutants into a municipal sanitary sewer system, you do not need an NPDES permit, but you should ask the City of Hemet about the permit requirements. If you discharge pollutants into a municipal storm sewer system, you may need a permit depending on what you discharge. You should ask the NPDES permitting authority.
