(A) In addition to any other activity prohibited by this chapter or the Corona Municipal Code, no person shall:
(1) Establish, use, maintain or continue an illicit connection or commence or continue an illicit discharge to the storm drain system. This prohibition is expressly retroactive and applies to connections made in the past, regardless of whether made under a permit or other authorization or whether permissible under the law or practices applicable or prevailing at the time of the connection.
(2) Engage in activities which will or may result in urban runoff entering the storm drain system which contains pollutants that have not been reduced to the maximum extent practical.
(3) Engage in activities which will or may result in discharges from the storm drain system which cause or contribute to a nuisance or exceedances of receiving water quality standards.
(4) Throw, deposit, leave, maintain, keep or permit to be thrown, deposited, placed, left or maintained, any pollutant in or upon any street, alley, sidewalk, storm drain, inlet, catch basin, conduit or other drainage structures, business place, or upon any public or private plot of land in the city. The only exception being where such pollutant is being temporarily placed in an appropriate container with a spill containment system for later collection and removal. No person shall cause or permit any dumpster, solid waste bin, or similar container to leak such that any pollutant is discharged into any street, alley, sidewalk, storm drain, inlet, catch basin, conduit or other drainage structures, business place, or upon any public or private plot of land in the city.
(5) Cause or contribute a discharge that would result in or contribute to a violation of the city's NPDES permit and any amendment, revision or reissuance thereof, either separately considered or when combined with other discharges, is prohibited. Liability of any such discharge shall be the responsibility of the person(s) causing or responsible for the discharge, and such person(s) shall defend, indemnify, and hold harmless the city, its elected officials, officers, employees and agents, in any administrative or judicial enforcement action relating to such discharge.
