(A) The Federal Clean Water Act (33 U.S.C.1251 et seq.) provides for the regulation and reduction of pollutants discharged into the waters of the United States by extending National Pollutant Discharge Elimination System (hereinafter “NPDES”) requirements to storm water and urban runoff discharge into municipal storm drain systems.

(C) The city is a co-permittee under the “Waste Discharge Requirements for Municipal Separate Storm Sewer System (MS4) Discharges within the Coastal Watersheds of Los Angeles County, Except Those Discharges Originating from the City of Long Beach MS4” (Order No. R4-2012-0175), NPDES Permit No. CAS004001, effective December 28, 2012, issued by the California Regional Water Quality Control Board-Los Angeles Region, and any successor permit to that permit (the “Municipal NPDES Permit”), and, as a co-permittee under the Municipal NPDES Permit, the city is required to implement and enforce the requirements contained in the Municipal NPDES Permit, to control discharges to and from those portions of the MS4 over which it has jurisdiction, and to hold dischargers to the MS4 accountable for their contributions of pollutants and flows.
(D) Part III, Section A. of the Municipal NPDES Permit requires the city to prohibit, for the portion of the MS4 for which it is an owner or operator, non-storm water discharges into the MS4, except where such discharges are identified and in compliance with Part III.A. of the Municipal NPDES Permit.
