CITY OF CORONA National Pollution Discharge Elimination System (NPDES) 2006-2007 ANNUAL REPORT NARRATIVE REPORT The current NPDES Municipal Storm Water Permit, Santa Ana Regional Water Quality Control Board (Regional Board) Order No. R8-2002-0011 which was issued on October 25, 2002, requires the City to submit an Annual Progress Report to the Riverside County Flood Control and Water Conservation District (RCFC & WCD). The report should contain the City’s progress in its implementation of the various provisions of the NPDES program. The City of Corona, in its goal to continuously implement a strong municipal storm water management program, is consistently seeking, developing and implementing best management practices for its facilities and the community. The following is an abstract of this effort: Infrastructure Maintenance: • The City’s street maintenance program includes a twice per month sweeping schedule for residential and commercial areas. Street medians and intersections are swept once per month. Total street miles swept for the Fiscal Year 2006 – 2007 are 20,167.32 miles. Approximately 2,845 tons of collected debris was properly disposed of. • A video reconnaissance survey of the City’s catch basins was implemented in August 2001 and is on-going on an as-needed basis at this time. • The City continued its catch basin labeling program this fiscal year by ensuring that each catch basin inspected throughout the City was labeled with a curb marker. Street maintenance crews placed a marker if one was not already in place. Approximately 1,500 curb makers have been placed over the past three years. • The Public Works Department is currently improving a computerized database and program that will assist in identifying catch basin location, maintenance and cleaning schedules, debris description including type and volume of debris collected and stencil/label information. Portable tablets have been purchased for all field staff. Currently staff are being trained in the office with the new program. We anticipate full usage in the field in late Fall 2007. Q:\NPDES\Santa Ana Annual Reports\Annual Reports\2007 Rpt forms\Permittee Submittals\Corona\Corona 06-07 Narrative Report_f.doc Public Education: • The City annually participates in a number of public education events. At these events various forms of public education materials are handed out to the public. For this year, we participated in the following events: • Low Flush Toilet Fair, March 24th 2007 • Distributed adult and kids bags filled with NPDES educational materials and dustpans to approximately 350 Corona residents that attended the event • Household Hazardous Waste Collection events. The City coordinates the distribution of used oil waste containers with assistance from WRCOG, four times per year. • Inner-coastal Watershed Cleanup Day, October 28th 2006 • City supplied equipment and personnel for the event held in City of Corona. Approximately 30 volunteers collected two tons of trash from the Temescal Wash. • City of Corona Safety Fair, June 27th 2007 • NPDES staff distributed approximately 100 pieces of educational materials to City staff during this one day event. • Landscape Design and Irrigation Classes • City of Corona residents have the opportunity to attend a series of classes sponsored by our Department of Water and Power held at our Corporation Yard Training Center. This fiscal year a class was held October 21, 2006. Classes cover plant selection and irrigation practices to reduce over watering that could end up as urban runoff in our storm drain system. • Keep Corona Beautiful – litter/recycling campaign • The City participated in various special events, and instituted a program for utilizing grant money from the Department of Conservation. The Public Works Department purchased a 26 foot trailer and retrofitted it into a “Litter Abatement Vehicle”. Complete with light bars, generator, exterior lighting, cones, road closure equipment, trash and recycling containers and a traveling restroom for the crew, this Litter Abatement Vehicle is equipped to deal with many situations like: collecting litter from the public right of way, cleaning up major sections of the community of debris and responding to many different situations. • Corona Adopt-a-street Program • The adopt-a-street program partners community organizations and local businesses to keep our community clean. This partnership is an ideal combination of community service and business by allowing organizations to earn community service hours and fundraise by partnering with a local business who receives recognition via a posted sign in the adopted area. A local business sponsors a one-half mile street segment for a period of one-year and is responsible for maintaining the street litter free with a bi-monthly Q:\NPDES\Santa Ana Annual Reports\Annual Reports\2007 Rpt forms\Permittee Submittals\Corona\Corona 06-07 Narrative Report_f.doc cleaning schedule. Currently the Corona General Employees Association sponsors the donation for Raney Intermediate Junior High-school. • This fiscal year the City inspected approximately 491 businesses as part of our industrial/commercial inspection program which includes distribution of educational materials to business owners on proper Best Management Practices to prevent pollutant exposure to storm water and eliminate non-storm water discharges. This effort is in addition to the facilities surveyed as part of the County’s Compliance Assistance Program (CAP). Program Enforcement: • To closely monitor the compliance of new developments with the requirements of the NPDES program, the Public Works Department (Land Development section) requires the submittal of approved SWPPP plans and copies of the NOI and WDID No. prior to issuance of any grading permit. • The Public Works Department has prepared an NPDES Development Project Implementation Plan as a guidance tool for implementing Water Quality Management Plan (WQMP) requirements and site design and source control BMPs for non-WQMP projects from initial submittal through plan check and post-construction. Implementation of the WQMP requirements by the project owner is ensured through execution of a WQMP Maintenance Agreement with the City or through project Conditions, Covenants, and Restrictions (CC&Rs), both recorded against the title to the property. This fiscal year we received 30 Preliminary and Final WQMPs for in-house review and approval. • A GIS tracking system for the structural BMPs included in the approved WQMPs continued this year. This system tracks the facility maintenance frequencies, responsible parties, BMP types, installation dates, and locations of the BMPs. • The NPDES section actively works with the Fire Department, Code Enforcement, Source Control and Public Works Inspection staff to respond to any incidents that pertain to possible NPDES violation. In fact we have a NPDES staff member that is dispatched to any incident and is usually on site within minutes of reporting the incident. We provide enforcement to any NPDES violation including immediate clean up of the violation, verbal warning, and public education to the violator including handing out public education material. The NPDES Section also responds directly to complaints from the general public in regards to NPDES violations. We respond to those complaints just as fast as we respond to other complaints and we provide enforcement and educational support as needed. • The NPDES section has been able to better track facility compliance and follow- up enforcement actions at industrial/commercial facilities with implementation of an industrial/commercial inspection database. The database keeps track of inspection information at each site, enforcement actions, and schedule for the next or follow-up inspection. It is a useful tool for enforcing our stormwater ordinance Q:\NPDES\Santa Ana Annual Reports\Annual Reports\2007 Rpt forms\Permittee Submittals\Corona\Corona 06-07 Narrative Report_f.doc at facilities determined to contribute a significant pollutant load to the storm drain system. Municipal Strategy: • The implementation of our Municipal Facility Strategy continued this year. We performed facility inspections to determine compliance with BMP requirements and any need for revisions and updated all site-specific facility pollution prevention plans. As noted in the report, the streets solid waste transfer station was relocated to City of Corona Wastewater Treatment Plant No. 2 this year. This facility is self contained with surface inlets connected to the treatment plant headworks, thereby eliminating potential runoff contamination to the storm drainage system. Staff Training: • For this fiscal year, Public Works, DWP and Fire Department staff attended a half-day training seminar sponsored by Riverside County Flood Control District on Industrial/Commercial Storm Water Compliance Inspection. DWP, Parks and Community Services, and Public Works Department staff attended a half-day seminar on Municipal Activities Best Management Practices. • All of the Public Works inspectors are presented updated information on NPDES issues at a weekly staff meeting. In addition, Public Works staff attended a half- day training seminar sponsored by Riverside County Flood Control District on Storm Water Best Management Practices for Construction Activities. • Public Works NPDES staff attended a one-day seminar on Stormwater Management Issues and Solutions and Regional TMDL. Public Works staff also participated in a webcast seminar series sponsored by USEPA for Pollution
