Summary
Roseville makes it unlawful to discharge sewage, industrial waste, pollutants, garbage or rubbish into any municipal storm drain, watercourse, natural outlet, creek or channel except under a listed exemption or a state/federal NPDES permit. City Code Section 14.20.120 backs the city's own NPDES permit, Order No. 2013-0001-DWQ, Permit No. CAS000004, and is enforced by the environmental utilities director and city engineer.
It is unlawful to discharge, permit to be discharged, or cause to be discharged any sewage, industrial waste, pollutant, garbage, or rubbish into any municipal storm drain system, watercourse, natural outlet, creek, or channel, except in accordance with the provisions of Chapter 14.20.130, or with the terms of a state or federally issued NPDES permit or city stormwater permit. Non-stormwater runoff discharge that is not incidental is prohibited, unless otherwise specified in Section 14.20.130.
Full Breakdown

Violations & Fines
Section 14.20.410 makes it unlawful to violate any provision of the chapter, chargeable as an infraction or misdemeanor at the city attorney's discretion, with each day of a continuing violation a separate offense under Section 14.20.520. Section 14.20.430 lets the director or city engineer order a discharger to abate and clean up a spill within 72 hours of notification, or abate an uncontrolled pollutant source within 30 days, and Section 14.20.460 lets the city treat an uncorrected violation as a public nuisance and abate it at the property owner's expense, with a lien if the invoice goes unpaid 60 days. A recipient of a cease-and-desist order or citation may appeal to the board of appeals within 10 days under Section 14.20.450.
