Summary
Sparks bars anyone from letting pollutants reach its storm sewer system and requires property owners and businesses to actively prevent runoff contamination under Municipal Code Section 13.65.020. The rule covers everything from pesticide storage to sweeping debris into a gutter, and it's enforced by the Public Works Department under the city's shared NPDES permit.
A.Any person engaged in activities which will or may result in pollutants entering a storm sewer system shall undertake pollution prevention measures and controls to the maximum extent practicable (MEP) to reduce such pollutants. Examples of such activities include, but are not limited to, proper use and disposal of household chemicals such as pesticides and fertilizers; and ownership, use and maintenance of facilities which may be a source of pollutants such as parking lots, fueling stations, industrial facilities, retail establishments, etc.B.No person shall throw, deposit, leave, maintain, keep, or permit to be thrown, deposited, placed, left or maintained, any refuse, rubbish, garbage, animal waste, or other discarded or abandoned objects, articles, and accumulations, in or upon any street, alley, sidewalk, storm sewer inlet, catch basin, conduit or other drainage structures, parking area, or upon any public or private plot of land so that the same might be or become a pollutant, except where such pollutant is being temporarily stored in properly contained waste receptacles or is part of a well defined compost system.
Full Breakdown
020 is the general operating duty behind them: anyone whose activities could send pollutants into a storm sewer, whether the municipal separate storm sewer system (MS4) or a private system, must take pollution prevention measures 'to the maximum extent practicable' (MEP). The code names parking lots, fueling stations, industrial facilities, and retail sites as typical pollutant sources, alongside everyday activities like using and disposing of pesticides and fertilizers. Subsection B separately bans depositing refuse, rubbish, garbage, animal waste, or other discarded material into any street, alley, sidewalk, storm sewer inlet, catch basin, or drainage structure, unless it's contained in a proper waste receptacle or a defined compost system.
050 separately outlaws any illicit connection to the MS4. 040 require property owners to monitor dumpster and loading dock areas, contain spills immediately, and train employees on storm water pollution prevention. 130 requires anyone in charge of a facility to notify the city's Environmental Control Division immediately upon learning of any suspected or confirmed pollutant release headed for the storm system.
Violations & Fines
Discharging into the storm system outside these rules is a title violation enforceable by the Public Works Director, who can order corrective action, revoke an environmental control permit, or refer the matter for civil or criminal penalty. The Public Works Director also has a statutory right of entry under Section 13.65.150 to inspect any facility discharging into the MS4 and pull samples without notice where pollution is suspected.
