Full Breakdown
16 governs illicit discharge and erosion control citywide. 070, Illicit Discharges, prohibits discharging or causing to be discharged into the City storm drain system or watercourses any materials, including pollutants or waters containing pollutants, that cause or contribute to a violation of applicable water quality standards other than storm water. The ordinance lists narrow exceptions: water line flushing, landscape irrigation, diverted stream flows, rising ground water, foundation or footing drains not tied to floor drains, air conditioning condensate, individual residential car washing, de-chlorinated swimming pool discharge, emergency firefighting water, and residential street wash water, among others.
020 is the Public Works Director or a designee. 080 layers on erosion control: any person disturbing one acre or more of ground, or a smaller parcel that is part of a larger common plan of development, must obtain a UPDES General Construction Storm Water Permit from the Utah Division of Water Quality and keep a Stormwater Pollution Prevention Plan (SWPPP) on site covering maintenance easements and inspection access. 060 separately bars tracking mud, dirt, gravel or concrete rinse water onto public streets and requires drivers to clean tires and undercarriages before entering paved rights-of-way. 15.
Violations & Fines
The Public Works Department can issue a stop-work order halting construction and revoking a stormwater permit for any violation. Under Section 13.16.100, the City may also issue a written notice of violation requiring cleanup, monitoring, or cessation of the discharge, and any violation is a class B misdemeanor on a first offense, with subsequent offenses within two years punishable under state law. Leaving mud or debris on a street can be treated as a nuisance under Chapter 6.24 with each day a separate offense, and the City may install erosion controls itself and bill the contractor or owner an added 25 percent penalty charge, which can be assessed against the posted bond.
