Compliance with National Pollutant Discharge Elimination System (NPDES) Permit Program . As authorized by the Clean Water Act and implemented by the United States Environmental Protection Agency, the National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Point sources are discrete conveyances such as pipes or man-made ditches. . The City's NPDES compliance activities include: i. Inspection and maintenance of the stormwater facilities (treatment ponds, drainage outfalls, creeks & canals, swales, inlets, catch basins, etc.) 11. Maintaining an inventory of all stormwater facilities within the City limits (public and private including the county's and state's) 111. Public outreach and education IV. Preparation and submittal of an annual report that must be approved by FDEP Informational Agenda Item 100 April 11, 2007 Page 2 of 4 2. Active Participation in the Total Maximum Daily Load (TMDL) Program . Lake Jesup is an impaired water of the state, meaning that it does not meet water quality standards as determined by the Florida Department of Environmental Protection (FDEP). Lake Jesup is impaired with excessive concentrations of nitrogen and phosphorous. . TMDLs establish the maximum amount of a pollutant that a water body can assimilate without causing exceedances of water quality standards. The TMDL implementation is mandated under the federal Clean Water Act and the Florida Water Restoration Act. . FDEP has established the TMDLs for Lake Jesup and a Basin Management Action Plan (BMAP) is now being developed by the basin's major stakeholders to identify projects and other actions necessary to bring Lake Jesup into compliance with the TMDL. The City actively participates in the BMAP process, primarily through attendance at monthly BMAP development meetings. . The City has entered into a TMDL Interlocal Agreement with Seminole County and all incorporated cities that will facilitate implementation ofTMDL-related regional projects. . The total cost (and the City's share) to implement the BMAP remains undetermined; however, the basin stakeholders have generally concluded that current funding sources are unlikely to be adequate to cover the BMAP implementation. 3. Participation in Regional Projects and Planning Activities . Participation and financial contribution to the Howell Creek Basin Management Study with St. Johns River Water Management District, Orange and Seminole Counties and its incorporated cities. This study consists of a comprehensive basin management study for flood control and water quality improvements in the Howell Creek Basin. . The Solary Canal Regional Stormwater Treatment Facility is a SJRWMD project located at the northeast comer of the City limits (the old Minter property). The project is in the City of Winter Springs but treats runoff primarily from Oviedo. The City has actively participated in the planning and review of this project. . Financial participation for the Seminole County Watershed Atlas, a water resources website providing educational and useful information to citizens and professionals such as water quality & quantity data . Active membership in the Florida Stormwater Association and regular attendance at local seminars on storm water management Informational Agenda Item 100 April 11, 2007 Page 3 of4 . Participation in the Middle St. Johns River Alliance Technical Advisory Committee (Programs and Projects for the St. Johns River) 4. New Development Stormwater Review . All new development is reviewed for compliance with the City Code, SJR WMD stormwater quality guidelines, and good storm water engineering practice. Projects are reviewed during the planning, design, construction, and final acceptance stages. . The City has approved and/or recommended stormwater treatment standards above the minimum required by SJRWMD on projects in the vicinity of Lake Jesup. . The City supports SJRWMD's recent implementation of pre-post nutrient loading criteria for projects in the Lake Jesup basin. This criteria provides additional stormwater treatment facilities to ensure that new developments have no net increase in pollutant discharges. . The City verifies that all new construction projects have obtained an NPDES permit. . City inspectors review and verify that required erosion control measures are in place throughout construction project duration. 5. Capital Improvements and Special Projects . The City's Stormwater Management Master Plan was initially prepared in 1993 and updated in 2005 . Stormwater Capital Project List is reviewed and updated annually . Significant projects completed over the past several years include: i. Removal of debris and clearing of the City's creeks and waterways 11. Maintenance and clearing of the canal outfall to Lake Jesup at Orange Avenue 111. Erosion control and bank stabilization project at Howell Creek at Chelsea Parc subdivision IV. Town Center Roadway and Drainage Improvements v. North Tuscawilla Road Drainage Improvements Informational Agenda Item 100 April 11, 2007 Page 4 of 4 6. Participation in FEMA's National Flood Insurance Program - Community Rating System (NFIP-CRS) . The City's participation in the NFIP-CRS provides rating credits for flood insurance policies, which reduce flood insurance premiums for City residents . Participation requires preparation of an annual report and documentation of various stormwater management services provided by the City 7. FEMA Flood Map Modernization . FEMA is currently in the process of updating and modernizing the NFIP Flood Insurance Rate Maps (FIRM), with partnership and cooperation with various federal, state, and local government agencies . The City agreed to be a Community Partner with FEMA on the map modernization process, which should be complete by the end of the year 8. Additional Items . The City routinely inspect and promotes maintenance of private stormwater systems . City stormwater staff provides courtesy technical inspections for residents, businesses, and HOA's . The City pursues funding opportunities for stormwater projects through grant applications . A storm water utility rate study was performed in 2005 ATTACHMENTS: None COMMISSION ACTION:
