  1. Oneonta and Municipal Separate Storm Sewer Systems (MS4) Designation • Outline: • Big Picture and the Chesapeake Bay • Coverage Under DEC’s GP-0-08-002 • Six Minimum Control Measures • Next Steps

  2. Phase 5 Scoping Scenarios

  3. Phase 5 Scoping Scenarios

  4. Phase 5 Scoping Scenarios

  5. Nonpoint source runoff modeling A comparison of a forested watershed and an urban watershed on the South Carolina Coast -Christopher W. Corbett et al 1997 Journal of Experimental Marine Biology and Ecology • Simulation results showed a 5.5 X greater volume and sediment yield from urban settings compared to forested settings • Ratio of rain volume to runoff volume was 14.5% higher in urban settings when compared to forested settings • Impervious Surfaces

  6. Local Examples of Stormwater Runoff

  7. Urban Sources of Non-Point Source Stormwater Pollution • Construction Site Runoff • Litter and Debris From Roads and Parking Lots • Excess Fertilizer and Pesticides • Eroding Streambanks • Vehicle Maintenance – Oil and Detergents • and many more……

  8. Worsening water quality, locally and regionally, could result in the City of Oneonta being required to obtain coverage under the:State Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater Discharges from Municipal Separate Storm Sewer Systems (MS4’s). Permit No. GP0-08-002

  9. GP-0-08-002 • 50 + Points of Compliance, many are required to be met annually • Development and Implementation of a Stormwater Pollution Management Plan (SWMP) • Six Minimum Control Measures • Annual Assessment, Recordkeeping, Reporting & Certification

  10. Timetable • Notice of Intent must be submitted within 6 months of DEC notification requiring coverage • Years 1-3: Development and gradual implementation of SWMP, Annual Reports • Year 3+: Full implementation of SWMP

  11. Six Minimum Control Measures - Programs • Public Education & Outreach • Public Involvement & Participation • Illicit Discharge Detection & Elimination • Construction Site Stormwater Runoff Control • Post-Construction Management • Pollution Prevention & Good Housekeeping for Municipal Operations

  12. Public Education & Outreach • Identify pollutants of concern, waterbodies of concern, geographic areas of concern and targeted audiences • Develop a education and outreach program designed to describe the impacts of stormwater, pollutants and their sources, steps that can be taken to reduce runoff. • Develop, record, assess and modify measurable goals. • Select activities and goals to ensure reduction of the Pollutant • Reporting (Year 1): list of pollutants of concern and list outreach activities for targeted audiences

  13. Public Involvement & Participation • Comply with all state open meeting laws • Develop and implement a public participation program that identifies key stake holders. • Describe activities that provide access to those who want it. • Identify a local point of contact for concerns. • Public presentation of a draft annual report. • Develop, record, assess and modify measurable goals • Select public activities and measurable goals to ensure reduction of pollutants. • Report activities and progress

  14. Illicit Discharge Detection & Elimination (IDDE) • Any discharge to a municipal system that is not composed entirely of storm water. For example, • Sanitary sewage • Garage drain effluent • Waste motor oil

  15. Illicit Discharge Detection & Elimination (IDDE) - continued • Develop, implement and enforce a program to detect and eliminate illicit discharges • Map the location of all outfalls and storm sewersheds • Conduct a survey and map new outfalls • Prohibit by law illicit discharges and enforcement • Detect and address non-stormwater illicit discharges • Develop, record, assess and modify measurable goals • Select appropriate public involvement activities. • Reporting: Descriptions of resources available and steps taken (above) over 3 year time period

  16. Water line flushing Landscape irrigation Diverted streams Rising groundwater Uncontaminated groundwater infiltration Uncontaminated pumped groundwater Potable water discharges Foundation drains Air conditioning condensate Irrigation water Springs Crawl space and basement sump pumps Footing drains Lawn watering Individual car washing Flows from wetlands and riparian habitats Swimming pool discharges Street wash water Fire fighting activities “Exempt & Illicit Discharges”

  17. Construction Site Stormwater Runoff Control • Develop and implement a program that is equal to GP-0-08-001. Stormwater Pollution Prevention Plan (SWPPP) required for sites that disturb > 1 acre. • SWPPP review and acts on public complaints. • Provide law for enforcement that allows for site inspection and sanctions and contains requirements for site operators and control of construction waste • Educates construction site owners/operators, design engineers, municipal staff and ensures that site operators are trained • Maintains inventory of construction sites • Develop, record, assess and modify measurable goals • Select BMP’s and measurable goals to ensure reduction of pollutants. • Report on progress on above steps over 3 Years

  18. Post-Construction Management • Provides equal protection as GP-0-08-001. SWPPP required for sites that disturb > 1 acre, law or ordinance for enforcement • Includes a combination of appropriate structural and non-structural practices • Describes procedure for SWPPP review by qualified professionals • Establish and maintain an inventory of post-construction practices and ensures long term maintenance • Develop, implement and provide resources • Develop, implement and assess measurable goals • Report on progress on above steps over 3 Years

  19. Pollution Prevention & Good Housekeeping for Municipal Operations • Addresses municipal operations that contribute pollutants of concern • Assessment of all municipal operations every 3 years. • Determines management procedures that will reduce and prevent discharge of pollutants • Prioritizes operations, addresses priorities and includes training. • Develop, record and assess goals and select appropriate BMP’s • Report on progress on above steps over 3 Years

  20. Pollution Prevention & Good Housekeeping for Municipal Operations - continued • Reporting • Complete by the end of Year 1 • identify operations, facilities and infrastructure to be included in program, describe priorities, management practices (policies and procedures) and identify staff and equipment available. • Initiated in Year 2 and complete by the end of Year 3 • describe housekeeping program, training program and number of employees trained. • Complete by End of Year 3 • a description of management practices.

  21. SWCD Oneonta Stormwater Program • Mapping of stormwater inlets – complete • Mapping and inspection of outfalls – complete by end of August 09 • Stormwater presentation to municipal officials – June 09 • Working Group Meetings with appropriate municipal departments – July through December 09 • Public Education and Outreach – September through December 09 • SWCD Municipal Hydroseeding Program - ongoing

  22. Inlets Found within Town & City Boundaries

  23. Next Steps • Training for private sector contractors on sediment and erosion control – tentative date December 09 • Further development of Mapping tool – connect inlet and outflow ‘dots’ • Further development of any of the Six Minimum Control Measures
