Chapter 14.20 — STORM WATER CONTROL

The city council adopts this Chapter based upon the following:

A.

The Federal Clean Water Act, the implementing regulations for the National Pollutant Discharge Elimination System (NPDES), and the California Porter-Cologne Water Quality Control Act provide for the regulation and reduction of pollutants discharged to waters of the state and United States by extending NPDES requirements to storm water and urban runoff discharges to and from the storm drain system.

B.

The city is required to enroll as a permittee under the State of California's Waste Discharge Requirements for Small Municipal Separate Storm Sewer Systems (Order No. 2013-0001-DWQ) and the NPDES General Permit No. CAS000004 (general permit). Under the provisions of the general permit, the city is required to possess the necessary legal authority and implement appropriate procedures to regulate the entry of pollutants and non-storm water discharges into the storm drain system.

(Ord. No. 993 N.S. § 1, 7-2-2013)

The purpose of this chapter is to ensure the health, safety and general welfare of citizens, and to protect and enhance the water quality of watercourses and water bodies in a manner pursuant to and consistent with the Federal Clean Water Act (33 U.S.C. § 1251 et seq.) and the Porter-Cologne Water Quality Control Act (Water Code § 13000 et seq.) by reducing pollutants in storm water discharges to the maximum extent practicable and by effectively prohibiting non-storm water discharges to the storm drain system.
