Menifee discharges urban runoff under Riverside County's NPDES MS4 permit. The city is a co-permittee in the Santa Margarita Region (San Diego RWQCB) for the southern Murrieta Creek/Santa Margarita watershed and the Santa Ana Region (Region 8) for the northern portion of the city. Developers must prepare a Water Quality Management Plan (WQMP) and follow Best Management Practices (BMPs) for construction-phase runoff. Illicit non-stormwater discharges (washwater, paint, oil, pool drainage with chlorine) to storm drains are prohibited.
Menifee participates in the Riverside County Flood Control & Water Conservation District (RCFC&WCD) MS4 program. Most of Menifee drains north through Salt Creek into the Santa Ana watershed (Region 8 NPDES Order R8-2010-0033, MS4 Permit CAS618033), while southern portions drain to the Santa Margarita system (Region 9 Order R9-2013-0001 / R9-2015-0100 amended permit). Both permits require new development and redevelopment over 10,000 sq ft (or single-family hillside, ESA-adjacent, parking lots ≥5,000 sq ft, restaurants, gas stations, auto repair) to prepare a project-specific WQMP that retains/treats the 85th-percentile 24-hour storm via Low Impact Development (LID) BMPs such as bioretention, infiltration, biofiltration, or harvest-and-use. Construction sites ≥1 acre must obtain coverage under the State Construction General Permit (Order 2009-0009-DWQ, as amended) by filing a Notice of Intent on SMARTS and preparing a Stormwater Pollution Prevention Plan (SWPPP) signed by a Qualified SWPPP Developer (QSD). Sites under 1 acre still must implement an Erosion and Sediment Control Plan reviewed by city Engineering. Illicit discharge is prohibited; only uncontaminated dewatering, fire hydrant flushing, and de-chlorinated pool water (after pH neutralization and visible-chlorine elimination) are conditional exempt discharges under the MS4 permit.
Illicit discharges, missing WQMP for qualifying projects, or failure to implement SWPPP BMPs are violations of the MMC and the Federal Clean Water Act. Penalties include stop-work orders, administrative citations, and state-level fines up to $10,000/day under Water Code §13385. Repeat violators may be referred to the RWQCB for prosecution.
