ORDINANCE 1347ORDINANCE NO. 1347 AN URGENCY ORDINANCE IMPLEMENTING THE STANDARD URBAN STORM WATER MITIGATION PLAN OF THE CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD FOR THE LOS ANGELES REGION BY AMENDING CHAPTER 7 OF TITLE 5 OF THE EL SEGUNDO MUNICIPAL CODE IN ITS ENTIRETY. The Council of the City of El Segundo does ordain as follows: SECTION 1: The City Council finds as follows: A. The Federal Water Pollution Control Act (33 U.S.C. §§ 1251 -1387; "Clean Water Act" or "CWA "), as implemented by the United States Environmental Protection Agency ( "EPA "), requires that the city adopt plans and programs for stormwater quality management; B. The 1972 amendments to the CWA prohibit the discharge of any Pollutant to waters of the United States from a point source unless the discharge is authorized by a permit issued pursuant to the National Pollutant Discharge Elimination System ( "NPDES ") required by 33 U.S.C. § 1342; C. Municipal separate storm sewer systems ( "MS4s ") which convey urban runoff, including, without limitation, Storm Water runoff, are within the definition of point sources under the CWA; D. Pursuant to the CWA, the EPA defined the tern "Municipal separate storm sewer system" to mean a conveyance, or system of conveyances, including roads with drainage systems, municipal streets, curbs, gutters, catch basins, and storm drains owned or operated by a city, used for collecting Storm Water; E. CWA § 402(p) requires that the City obtain a permit for Storm Water and urban discharges through the City's MS4; F. Section 402(p) of the CWA further provides that NPDES permits will require controls to reduce the discharge of'Pollutants to the maximum extent practicable, including management practices and such other provisions as may be appropriate for the control of Pollutants; G. The EPA, in partial implementation of CWA § 402(p) adopted final rules, known as the "Phase I and Phase II Storm Water Regulations" at several places in Parts 9, 122, 123, and 124 of Title 40 of the Code of Federal Regulations ( "CFR" ); Page 1of19 H. In partial implementation of § 402(p) of the CWA, 33 U.S.C. § 1344(p), the Phase I Storm Water Regulations and the California Water Code, the California Regional Regional Water Quality Control Board — Los Angeles ( "RWQCB -LA ") issued a National Pollutant Discharge Elimination System ( "NPDES ") Permit and Waste Discharge Requirements for Municipal Storm Water and Urban Runoff Discharges within the County of Los Angeles, Regional Board Order No. 96 -054, NPDES No. CAS614001 (the "1996 Permit "), on July 15, 1996 to each City in Los Angeles County, including the City; I. Under the 1996 Permit, and in partial implementation of CWA § 402(p), 33 U.S.C. § 1344(p); the Phase I and Phase II Storm Water Regulations; and the California Water Code, the RWQCB -LA Board adopted Resolution No. R- 00 -02, approving and directing the Executive Officer of the RWQCB -LA to issue a Standard Urban Storm Water Mitigation Plan for Municipal Storm Water And Urban Runoff Management Programs in Los Angeles County setting forth the requirements to be implemented by all jurisdictions discharging storm water under the 1996 Permit, J. On March 8, 2000, the Executive Officer of the RWQCB -LA issued a Final Approved Standard Urban Storm Water Mitigation Plan For Los Angeles County And Cities In Los Angeles County (the "SUSMP ") setting forth the requirements to be implemented by all jurisdictions discharging storm water under the 1996 Permit, K. The State Water Resources Control Board, in Order WQ 2000 -11, modified the SUSMP by revising the definition of "Redevelopment," excluding Retail Gasoline Outlets from certain design standards, deleting the applicability of the SUSMP to `Environmentally Sensitive Areas," limiting the applicability of the SUSMPs to discretionary development and redevelopment in specified categories, applying the SUSMPs to Redevelopment projects only if they result in creation or addition of 5,000 square feet or more of impervious surfaces, deleting the requirement for funding by project proponents who receive waivers, and extended the SUSMP effective date deadline to February 15, 2001; L. In partial implementation of CWA § 402(p), the Phase I and Phase H Storm Water Regulations and the California Water Code, RWQCB -LA issued "Order No. 01 -182 NPDES Permit No Cas004001 Waste Discharge Requirements For Municipal Storm Water And Urban Runoff Discharges Within The County Of Los Angeles And The Incorporated Cities Therein, Except The City Of Long Beach" (the "2001 Permit ") on December 13, 2001, to cities in Los Angeles County, including the City; M. The 2001 Permit revised the SUSMPS to again revise the definition of "Redevelopment," to restore the applicability of the SUSMPS to Retail Gasoline Outlets, to restore the applicability of the SUSMP to "Environmentally Sensitive Areas," to delete the limitation of the applicability of the SUSMPs to Page 2 of 19 discretionary development and redevelopment and apply the SUSMPS to all project approvals in specified categories, and extended the deadline for the effective date of ordinances implementing the SUSMP to September 2, 2002; N. The City of El Segundo is a permittee under the 2001 Permit and therefore is required by federal and state law to implement all requirements of the 2001 Permit, including the SUSMP, as amended by the 2001 Permit; O. Under the California Constitution and the California Government Code, the City of El Segundo has authority to define public nuisances and to protect the public health and safety of the residents of and visitors to the City of El Segundo, and the environment, by abating public nuisances; P. The City of El Segundo has authority under the California Water Code to adopt and enforce ordinances imposing conditions, restrictions, and limitations with respect to any activity which might degrade the quality of waters of the state; Q. The City Council is obligated to take prudent steps to protect the City's property and its funds and taxpayers from exposure to liability, including the potentially enormous costs of litigation regarding natural resources allegedly damaged by pollutants allegedly transported through the City's storm drain system; R. The implementation of Pollutant control measures described in the Stormwater Quality Management Plan in furtherance of these purposes is exempt from the provisions of the California Environmental Quality Act (CEQA); Chapter 3 (commencing with Section 21100) of Division 13 of the Public Resources Code as provided in categorical exemption classes 1, 4, 5, 7, 8, 9, and 21 of the CEQA Guidelines (Title 14, California Code of Regulation §§ 15301- 15329); and S. The City Council has carefully considered the Ordinance and finds that it complies with the requirements of applicable federal and state law, and further that it provides an acceptable program for the conservation of water resources within the City of El Segundo and protection of the health, safety, and general welfare of its citizens. SECTION 2: Chapter 7 to Title 5 of the El Segundo Municipal Code ( "ESMC ") is amended in its entirety to read as follows: "CHAPTER 7 STANDARD URBAN STORM WATER MITIGATION PLAN IMPLEMENTATION 5- 7- 10:PURPOSE AND INTENT.
