  3. 3. Consent DecreeConsent Decree RequirementsRequirements • The City of Toledo’s Consent Decree with USEPA and OEPA requires the following • Improvements to the WWTP • Control of sanitary sewer overflows • Development and implementation of a Long Term Control Plan for Combined Sewer Overflows (LTCP)
  4. 4. Consent DecreeConsent Decree ImplementationImplementation • WWTP improvements • 11 major projects • $140 million • Sanitary Sewer Overflow Control • 13 major projects • $35 million • Combined Sewer Overflow Control • 26 projects (planned) • Over $250M (proposed)

  6. 6. SSO Control ProjectsSSO Control Projects
  7. 7. CSO Long Term ControlCSO Long Term Control PlanPlan • Subject of tonight’s meeting • Culmination of over two years of study • Involved the public and stakeholders along the way
  8. 8. Public Input for PlanPublic Input for Plan • Public input included: • 2 community telephone surveys • 6 public meetings • 17 Community Program Advisory Committee meetings devoted to the Long Term Control Plan
  9. 9. Long Term Control Plan –Long Term Control Plan – ContentsContents • Actions – projects or programs • Schedules – when projects will happen • Where – locations where projects will be constructed • Costs – project expenditures; financing plan
  10. 10. ObligationsObligations • The consent decree requires that the LTCP evaluate a range of CSO control alternatives based on: • Pollution reduction benefits • Instream water quality conditions • Construction and operations costs • The consent decree requires that work included in the plan be completed by August 31, 2016
  11. 11. City’s Combined AreaCity’s Combined Area
  12. 12. Existing ConditionsExisting Conditions • Currently 32 overflows • 17 square miles of CSO area • Discharge 33 times per year • Discharge 625 million gallons per year
  13. 13. CSO Control Work has beenCSO Control Work has been PerformedPerformed • The City constructed three major tunnel systems to store excess flow • The City has implemented a number of sewer separation projects to build separate sewer systems
  14. 14. CSO Area to TunnelsCSO Area to Tunnels
  15. 15. Sewer SeparationSewer Separation ProjectsProjects
  16. 16. Alternatives ConsideredAlternatives Considered • Flow storage and/or treatment • Storage basins and tunnels with screening and other treatment capability • Sewer Separation • Construction of new sewers for eliminating combined systems • Flow reduction/rerouting • Small-scale measures to reduce the amount of flow to the sewer system
  17. 17. Recommended PlanRecommended Plan • Proposed Plan • Reduces number of overflow locations from 32 to 23 • Reduces frequency from 33 to 4 (untreated) • Reduces volume from 625 MG/year to 144 MG/year • Reduces typical pollutant discharge by 86%-89% • Reduces bacterial discharge by 90%
  18. 18. Recommended PlanRecommended Plan • Includes 26 projects • Estimated cost of over $250M (2005 dollars) • Reduces Ottawa River discharge to 2 times/ year • Reduces Maumee River discharge to 4 times/ year • Reduces Swan Creek discharge frequency to 3 times/year, disinfects the discharge that does occur
  19. 19. Plan for Ottawa RiverPlan for Ottawa River
  20. 20. Plan for Maumee RiverPlan for Maumee River (Upper)(Upper)
  21. 21. Plan for Maumee RiverPlan for Maumee River (Lower)(Lower)
  22. 22. Plan for Swan CreekPlan for Swan Creek
  23. 23. Implementation Time FrameImplementation Time Frame • Ottawa River: 2006 – 2014 • Maumee River: 2006 – 2016 • Swan Creek: 2007 – 2016
  24. 24. Selected Control MethodsSelected Control Methods • Storage basins • Storage pipelines • Optimization of existing tunnels • Addition of disinfection capabilities to tunnels • Flow reduction • Sewer separation
  25. 25. Storage Basin ExamplesStorage Basin Examples • Vast majority of work is below ground • Will require above ground building for support facilities • Takes about 2 - 3 years to construct Birmingham CSO basinBirmingham CSO basin Leib Screening/ DisinfectionLeib Screening/ Disinfection Facility - DetroitFacility - Detroit
  26. 26. Storage PipelineStorage Pipeline • Essentially large sewer underground that will provide storage volume • Small support building required in vicinity • Takes 1 – 2 years for construction
  27. 27. Expected Facility LocationsExpected Facility Locations • Storage Basins • Joe E. Brown Park OR Windermere Blvd. • I – 280 / Front Street interchange area • Private property at Oakdale and Miami • City property next to I-75 on north side of Maumee River • Storage Pipelines • International Park • Adjacent to Jamie Farr Park
  28. 28. Tunnel ImprovementsTunnel Improvements • Improve tunnel hydraulics to reduce frequency • Reduce flow area (Swan Creek South) • Improve cleaning, other operations items • Add disinfection capability
  29. 29. Facility LocationsFacility Locations
  30. 30. Sewer Separation/ FlowSewer Separation/ Flow Reduction AreasReduction Areas
  31. 31. Project CostsProject Costs • All costs are based on 2005 cost index • Actual costs at implementation will be impacted by the rate of inflation and the final project design • Estimated overall cost: >$250 million • Rates will be impacted by timing of projects and financing method uses
  32. 32. What is Next?What is Next? • Plan was submitted in draft form to USEPA • Conference call held with USEPA this afternoon • Report submittal delayed until December 16, 2005 at EPA request • Draft executive summary will soon be available on the TWI Web site, along with an area to provide comments • Public comments on the plan are welcome
