Moreno Valley participates in the Santa Ana Regional Water Quality Control Board MS4 permit program. Discharging anything other than clean stormwater into storm drains is illegal. Construction sites over 1 acre require a state SWPPP, and car-washing, pool draining, and painting runoff are restricted.
Moreno Valley is a co-permittee under the Santa Ana Regional Water Quality Control Board's Municipal Separate Storm Sewer System (MS4) permit, which enforces the federal Clean Water Act locally. Moreno Valley Municipal Code prohibits any discharge of non-stormwater into the city storm drain system, which flows directly to local creeks, the Santa Ana River watershed, and ultimately the Pacific Ocean. Illegal discharges include soapy car wash water, paint and paint-rinse water, pool and spa water containing chlorine, pesticides, oil, antifreeze, concrete wash, carpet-cleaning water, and pet waste. Allowed discharges are limited to irrigation runoff (minimized), rainwater, dechlorinated residential pool draining, and emergency firefighting. Construction sites disturbing 1 acre or more require coverage under the state Construction General Permit (CGP) and preparation of a Stormwater Pollution Prevention Plan (SWPPP) with best management practices (BMPs) like silt fences, fiber rolls, and stabilized construction entrances. Smaller sites still must implement erosion and sediment controls under city code. Industrial facilities along Moreno Valley's logistics corridor near March Air Reserve Base are subject to the Industrial General Permit with specific monitoring. Violations carry fines up to $37,500 per day under state law. Report illegal discharges to the Moreno Valley 311 app or Public Works.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Moreno Valley code enforcement directly for current fines, enforcement procedures, and hearing options.
