Utah County enforces stormwater management under its MS4 permit with UDEQ, requiring Stormwater Pollution Prevention Plans (SWPPP) for land disturbance over 1 acre. Provo and Orem operate separate MS4 programs. Utah Lake watershed protection is a priority given ongoing algal bloom concerns.
Utah County Land Use Ordinance Chapter 8 and the County Stormwater Management Plan implement federal Clean Water Act MS4 permit obligations administered by the Utah Division of Water Quality under UAC R317-8. Any construction disturbing 1 or more acres requires a UPDES Construction General Permit (CGP) and an onsite SWPPP. Provo City Code Title 17 and Orem City Code Chapter 28 mirror these requirements within municipal limits. New development must not increase peak runoff above predevelopment rates for the 2-year, 10-year, and 100-year storms. Utah Lake is a 303(d)-listed impaired water, so discharges within its watershed face extra scrutiny for phosphorus. Low impact development practices such as bioswales, infiltration trenches, and permeable pavers are encouraged. Illicit discharges of soaps, oil, paint, concrete washout, or sediment into curb inlets violate 33 USC §1342 and county code.
Illicit discharge to storm drains: administrative fines $500 to $10,000 per day plus cleanup costs. Construction without SWPPP: stop-work order and UPDES penalties up to $10,000 per day. Failure to maintain permanent BMPs: notice of violation and escalating daily fines.
