Footnotes: --- (6) ---

Editor's note— Ord. No. 4450, adopted July 17, 2012, repealed the former Ch. 9, §§ 6910, 6911, 6920—6922, 6930, 6931, 6940, 6950—6955, 6960, 6970—6978, 6980, 6990, and enacted a new Ch. 9 as set out herein.

Article 1. - General Provisions

6910 - Purpose and intent.

The purpose of this Chapter is to prescribe regulations as mandated by the Federal Water Pollution Control Act (commonly referred to as the Clean Water Act), codified at 33 U.S.C. §§ 1251 et seq., as amended, and the Porter-Cologne Water Quality Control Act, California Water Code §§ 13000 et seq., to effectively prohibit non-stormwater discharges into the County Storm Drain System, and to reduce the discharge of pollutants in stormwater to the maximum extent practicable. The intent of this Chapter is to ensure the health, safety, and general welfare of County residents, and protect and enhance water quality by controlling the contribution of urban pollutants to runoff which enters the County Storm Drain System and Receiving Waters of the County of Ventura.
