Jenny Chen - SWMP FINAL10-4-04 REV.docPage 3EXECUTIVE SUMMARYThis document presents the City of Chico’s Draft Storm Water Management Program (SWAP) for submittal to the RegionalWater Quality Control Board. The document has been prepared by Public Works – Engineering Division.The purpose of the SWMP is to present a program that is consistent with Federal and State regulations and to meet permittingrequirements. Specific objectives of this document include: presenting a review of the legal framework for the necessity ofbeing permitted and a brief background on pollutants, urban runoff, and the City’s storm water facilities; the program itself;estimated costs to implement the program; and penalties for failure to comply with regulations and the program.A. Legal Regulatory FrameworkThe 1987 Clean Water Act amendments required the U.S. Environmental Protection Agency (EPA) to develop a tieredimplementation strategy for the National Pollution Discharge Elimination System (NPDES) Storm Water Program.Phase I began in the early 1990s and covered municipalities and urban areas of 100,000 population and above. Phase IIregulations were published in the Federal Register on December 8, 19999. The Chico Urban Area has been identified asone which is being required to comply with NPDES Phase II permitting because it has been identified as an “UrbanizedArea” by the Bureau of Census, specifically, per regulation:Owners or operators of small, municipal, separate, storm sewer systems (MS4s) located in any incorporated city, county,or place under the jurisdiction of a governmental entity within a census-designated urbanized area. Small MS4s locatedin a census-designated urbanized area (such as the Chico Urban Area) must apply for a NPDES permit by March 10,2003. Some cities or counties may be partially located in census-designated urbanized areas. Only the portion located inthe urbanized area would be automatically regulated.In the Chico Urban Area, the County of Butte, City of Chico, Chico Unified School District, and California StateUniversity, Chico are required to develop a storm water management program that implements six minimum measuresfocusing on a Best Management Practice (BMP) approach. The BMPs chosen by the operators of the MS4s should bedesigned to reduce pollutants in urban storm water compared to existing levels in a cost-effective manner. BestManagement Practices include public education, treatment practices, operating procedures, and practices to control siterunoff, spillage, or leaks.NPDES permits are issued for five-year terms and generally follow a progressive pattern. This SWMP presentsstrategies, goals, priorities, and management activities for years 2003-2008. In the first five years of the program, thefocus is on establishing a program customized to local conditions using the following six minimum measures: education and outreach;Public participation/involvement;Construction site runoff control;Post-construction runoff control;Pollution prevention/good housekeeping; andProgram Evaluation Activities.Future permits will be issued based on using the knowledge gained during the first five-year permitting and putting it to workon improving water quality incrementally over time.Public Works has prepared the attached Draft SWMP to comply with NPDES Phase II requirements. A Draft SWMP andNotice of Intent is required to be submitted to the Regional Water Quality Control Board (RWQCB), Redding office, byMarch 10, 2003.B. City’s Efforts to ComplyThe City has been committed to improving the quality of urban runoff through the development and implementation of aproactive, comprehensive storm water management program that recognized its unique position in the Sacramento Riverwatershed and the need to protect these important resources.Public Works is responsible for the City storm water drainage conveyance system, which includes gutters, swells, ditches,culverts, storm drain inlets, catch basins, storm drainage pipes, and detention facilities. This conveyance system providesan opportunity for pollutants to reach waterways because motor oil, paint products, pet wastes, and chemicals used in3

Jenny Chen - SWMP FINAL10-4-04 REV.docPage 4homes and gardens are washed into street gutters and storm drains via rain water. Streets typically contain vehicleexhaust products, brake and tire materials, oil and grease, litter and other materials that can get flushed through the stormdrainage system. This mix of rain and other water is called urban runoff. If not managed, urban runoff and all itspollutants flow untreated through the storm drainage system into local creeks and flood control channels where it canharm wildlife, pollute fisheries, and negatively impact overall water quality.The City has been working with other agencies and operators in the Chico Urban Area to provide for consistency in theChico Urban Area Storm Water Management Programs. Those agencies include the County of Butte, Chico UnifiedSchool District, and Chico Area Recreation Department. Representatives from these agencies met biweekly for severalmonths to draft their programs. By working together, the program for each agency in the Urban Area will be consistentin approach.C. Storm Water Management ProgramThe attached program will guide staff activities related to storm water control with the objective of this program to: Effectively manage and coordinate implementation of the storm water program; Identify and eliminate illicit connections and illicit discharges to the storm drain system; Reduce storm water impacts associated with development and redevelopment projects; Reduce storm water quality impacts associated with public agency activities; Increase public knowledge about the impacts of storm water pollution and about actions that can be taken to preventpollution. Increase knowledge and understanding about the quality, quantity, sources, and impacts of urban runoff. Evaluate the effectiveness of implementing storm water management programs.1. Purpose and Objective of the Storm Water Management ProgramThe purpose of the SWMP, through education, inspection, response, and, if required, water quality monitoring, is toprevent pollutants from entering the storm drainage system. The objectives of the SWMP are to provide guidance tothe public and businesses, and act as a coordinating entity towards a cohesive storm water program. An NPDESPhase II SWMP must meet six minimum controls, use best management practices (BMPs) to the maximum extentpracticable, and achieve measurable goals.2. The Storm Water Management Program: Six Minimum Control MeasuresThe following is a brief overview of the six minimum elements contained in the Draft SWMP and how the City plansto incorporate them.a.b.c.Public Education and Outreach:Generate awareness by educating citizens about the storm water system and the impact of polluted stormwater on water quality through educational materials and other outreach programs, such as;i.Storm drain stencilingii.Developing clean water business partnersiii.Sponsoring community eventsiv.Developing and maintaining a storm water web sitev.Developing media campaignsvi.Sponsoring water-wise pest control programsvii.Developing and implementing classroom programs, andviii.Surveying the publicPublic Participation/Involvement: Provide opportunities for citizens to be involved in developing andimplementing the storm water management program by sponsoring public meetings and panels and waterbody cleanups.Illicit Discharge Detection and Elimination;i.Develop and put into action plans to detect and eliminate illicit discharges to storm drainagesystems.ii.Develop a system map and inform citizens of hazards associated with illegal discharges andimproper wastewater disposal.iii.Create a storm water ordinance for regulating illegal discharges and for providing enforcementcapability.iv.Coordinate with other agencies with regard to code enforcement, building inspection, proper wastedisposal alternatives, updating storm drain system map, etc., and4

Permitting require that the City:i.Obtain feedback that will allow the City to continually improve the program.ii.Measure whether program activities are making progress toward reducing pollution in storm waterdischarges to the maximum extent practicable.iii.Provide information useful to other permit holders within the Chico Urban Area for modifyingjoint efforts and evaluating area-wide effectiveness of the SWMP activities.iv.Ensure compliance requirements of the City’s MS4 permit.v.Demonstrate that an appropriate level of effort is being that public funds are being utilized appropriately by targeting limited resources for the mostsignificant local environmental problems.vii.Submit annual reports to RWQCB.D.Costs to implement program1. Personnel. Public Works has identified in its Strategic Plan the need for additional staff in order to implementthe SWMP. Additional full-time positions: Senior Civil Engineer and Construction Inspector, as well as aportion of a Geographical Information System Analyst and Administrative Analyst, will be needed toimplement, monitor, enforce, and update this program required by the NPDES Phase II permit. The estimatedannual cost to fund these positions is 200,000.2. Operating Costs. Public Works anticipates that an annual operating budget of 200,000 to 300,000 should beestablished. Industry-wide implementation of this program has been running approximately 4- 6.00 per capitaannually.E.Failure to ComplyThe final permit regulations have not yet been issued. However, draft regulations indicate that a fine not to exceed 27,500 per calendar day can be made for permit violations. In addition, the Porter Cologne Act provides foradministrative, civil, and criminal penalties.5

It provides acomprehensive outline to direct the Program and its priorities and activities for the years 2003-2008. This Programwas developed as a requirement of Phase II of the National Pollutant Discharge Elimination System (NPDES)Program as ordered by the United States Environmental Protection Agency. The City’s Program is required byfederal law to be submitted by March 10, 2003. Other agencies within the Chico Urban Area were also automaticallydesignated by the United States Environmental Protection Agency pursuant to 40 CFR t122.32(a)(1) of the FederalWater Pollution Control Act (also referred to as the Clean Water Act) to comply with the Phase II requirements ofNPDES. Full implementation of the Program is required from each permittee by the end of the 5-year permit term.The City of Chico has a population of 60,400 within the City limits and 95,000 within the Urban Area as of theJanuary 2000 census. The City is 28.7 square miles, while the Urban Area encompasses 56 square miles. There arefive channels traversing the Urban Area that accept storm water runoff. They are Comanche Creek, Little ChicoCreek, Big Chico Creek, Lindo Channel, and Mud/Sycamore Creek. Big Chico Creek has spring-run Chinook andSteelhead habitat. Little Chico Creek is a tributary of Butte Creek, which is a spring-run Chinook stream. All of thechannels that traverse the Urban Area are tributary to the Sacramento River, a source of drinking and agriculturalwater for the State of California. The City operates and maintains a vast municipal storm drainage system thatconsists of miles of pipe, open drainage ditches and detention basins. The detention basins have water qualityfeatures incorporated into them. For many years, the City has been committed to improving the quality of urbanrunoff through the development and implementation of a proactive, comprehensive storm water managementprogram that recognizes its unique position in the Sacramento River watershed and the need to protect theseimportant resources.1-2Program OrganizationThe following provides a brief summary of the Program: Chapter 1: IntroductionThis chapter contains a brief introduction to the Program, information on Program organization, and adescription of the process for preparing this Program.

The approved Program will be in effect until it is replaced or updated inthe future. This Program serves to provide the description and approach to effectiveness evaluation. The AnnualReports will provide the specific activities and effectiveness evaluations accomplished for each fiscal year, based onthe direction and targets of the Program. Input from regulators and the public are important to the process ofdeveloping an effective Program during the initial permit term.Activities to obtain input included: Conducting meetings with the Regional Board, County departments, City officials and other interested parties Announcing availability of the Program Posting relevant information and the Program on the City’s web site Addressing public comments and include in the ProgramThe intent of the City is to have a current, relevant, and dynamic Program. In order to remain proactive andeffective, the Program should reflect the most recent information and needs. The Program will continue to evolveand improve through evaluations and feedback from various sources and activities. Input from regulators and thepublic throughout the permit term can be used to modify specific portions of the Program. Program effectivenessevaluations and Annual Reports are also used to facilitate review and adjustments to the Program.The Program will be revised as needed to adjust to future needs. As a living document, modifications may be madedirectly to the Program, subject to Regional Water Quality Control Board approval. Departmental reports will beprepared yearly to meet long-term Program objectives. The Annual Report to be submitted to the Regional WaterQuality Control Board by September 15th of each year will describe the activities and accomplishments of theProgram during the preceding year starting July 1st and ending June 30th.2.PROGRAM OVERVIEW2-1Program Implementation OverviewThe City’s Storm Water Management Program (Program) is a comprehensive program comprised of variouselements and activities designed to reduce storm water pollution to the maximum extent practicable (MEP) andeliminate prohibited non-storm water discharges in accordance with federal and state laws and regulations. Theselaws and regulations are implemented through National Pollutant Discharge Elimination System (NPDES) municipalstorm water discharge permits.The core Program Elements are: Public Education and OutreachPublic Participation/InvolvementIllicit Discharge Detection and EliminationConstruction Site Storm Water Runoff Control / New DevelopmentPost-Construction Storm Water ManagementPollution Prevention/Good Housekeeping for Municipal Operations and FacilitiesPage 9

Jenny Chen - SWMP FINAL10-4-04 REV.docPage 10The City of Chico recognizes the importance of effective storm water management. The Department of Public Worksprovides management and administration of the Program. The Department of Public Works is responsible for theCity storm water drainage conveyance system. Drainage facilities include gutters, swales, ditches, culverts, stormdrain inlets, catch basins, storm drainage pipes, and detention basins.2-2Regulatory BackgroundThe 1972 amendments to the federal Clean Water Act (CWA) prohibited the discharge of pollutants from pointsources to waters of the United States, unless the discharge was authorized by a permit issued under the NPDESpermitting program. The 1987 amendments to the CWA added Section 402(p), which defined storm waterdischarges from certain defined municipal and industrial activities as point sources required to be permitted by aNPDES permit. The amendments directed the U.S. Environmental Protection Agency (EPA) to adopt regulationsestablishing permitting requirements for municipal and industrial storm water discharges. The Phase I amendmentsalso required storm water discharges from municipal separate storm sewer systems (known as MS4 systems) servingpopulations greater than 100,000 to obtain coverage under a national surface water permit program. The EPA thendeveloped the Phase II Storm Water Program to include small MS4 systems in urban areas and operators of smallconstruction sites. In California, the federal National Pollution Discharge Elimination System (NPDES) permittingprogram is implemented through the Porter-Cologne Act, a part of the California Water Code, by the State WaterResources Control Board (State Board) and the Regional Water Quality Control Boards (Regional Boards).The EPA promulgated the NPDES Phase II regulations on December 8, 1999. Municipalities to be addressed inPhase II are defined as any municipal separate storm sewer system (MS4s) not already covered by the Phase Iprogram and defined by the Bureau of Census as an “Urbanized Area” or on a case-by-case basis on small MS4slocated outside of “Urbanized Areas” that the NPDES permitting authority designates.3.PROGRAM MANAGEMENT3-1IntroductionThis chapter presents the City of Chico Storm Water Management Program (Program) strategy, goals, priorities andmanagement activities for 2003-2008; legal authority; organization; planning and reporting activities; andbudget/staff resources. The continuing joint activities and coordination efforts of the City of Chico Area StormWater Permittees are included as well as activities in which the City of Chico implements portions of the Programthrough coordination with other programs and agencies.3-2Program StrategyThe 1987 amendments to the Clean Water Act added Section 402(p), which established National Pollutant DischargeElimination System (NPDES) permit requirements for municipalities to develop and implement comprehensivestorm water management programs. The storm water management program is required to describe the BestManagement Practices (BMPs) to reduce the discharge of pollutants in storm water runoff to the maximum extentpracticable (MEP). The MEP standard for municipal storm water management programs is also required by U.S.Environmental Protection Agency (EPA) Phase II storm water regulations promulgated on December 8, 1999.This strategy is pursued through the implementation of the City ’s Program. The Program is a living document withperiodic modifications to ensure that it is effectively carrying out activities to accomplish the Program mission. If itis determined that the Program is not adequately addressing particular pollutants or sources, minor modifications andadditions will be identified, which are submitted to the Regional Water Quality Control Board, for review andapproval.Significant changes in the scope or direction of the Program will be accomplished through a Program revision orupdate process in accordance with Regional Board procedures. Modifications to the Program will generally be madein response to effectiveness evaluations and to incorporate new Best Management Practices (BMPs). It is importantthat the Plan reflects current and improved BMPs and includes activities that have been shown to be successful inother storm water programs. Pollutant Removal: Will the BMP address the target pollutant?Page 10

Jenny Chen - SWMP FINAL10-4-04 REV.doc Page 11Regulatory Compliance: Is the BMP compatible with environmental regulations?Public Acceptance: Does the BMP have public support?Implementation: Is the BMP compatible with land uses, facilities, or the activity in question?Technical Feasibility: Is the BMP technically feasible considering soils, geography, etc.?Cost Effectiveness: Is the cost for the BMP commensurate with the environmental benefit?The City is committed to the continual expansion of the core Program Elements to further incorporate pollutantreduction activities. These strategies explore opportunities for participation in regional, state, and national efforts toaddress storm water pollution issues that are beyond the City’s ability to control at the local level.Expanding core Program activities will require increasing Program efficiency, utilizing experience from otherprograms, and participating in local and regional coordinated efforts.3-3Program Priorities and Management ActivitiesProgram priorities for 2003-2008 include implementing the Program and achieving regulatory compliance. Staff willcontinue to develop and improve Program activities to reduce storm water pollution to the MEP and eliminateprohibited non-storm water discharges, while facilitating understanding and involvement in storm water managementby various City departments such as Planning, Building, Operations and Maintenance, and Public works. Seeappendix E for responsible Departments. Another high priority for staff will be to keep abreast of the latesttechnology and approaches to storm water management. Program activities will also strive to encourageenvironmental stewardship and continue to build partnerships with other agencies and the community for activeparticipation in accomplishing the Program goals.3-4Legal AuthorityLegal authority and responsibility to implement a municipal storm water management program is provided in theFederal Clean Water Act (CWA), California Water Code, and associated regulations. The California EnvironmentalQuality Act (CEQA) and Subdivision Map Act also provide municipalities with autho

The City has been working with other agencies and operators in the Chico Urban Area to provide for consistency in the Chico Urban Area Storm Water Management Programs. Those agencies include the County of Butte, Chico Unified School District, and Chico Area Recreation Department. Representatives from these agencies met biweekly for several
