TMDL & Stormwater Accounting

  1. 1. Jeremy Sokulsky, PE, MBA<br />President<br />530-541-2980<br />jsokulsky@enviroincentives.com<br />tmdl&stormwater accounting<br />
  2. 2. LAKE CLARITY CREDITING PROGRAM<br />motivating effective action to improve lake clarity<br />
  3. 3. Have you seen projects like these?<br />
  4. 4. Limited connectivity to the waterbody results in small load reductions for the cost.<br />+$1.8m<br />+ 150kg<br />
  5. 5. Infiltration basin above the grade, so does not actually receive water.<br />+$0.8m<br />+ 0kg<br />
  6. 6. Reporting requirements do not result in follow-up maintenance.<br />+$0.75m<br />+ 0kg<br />
  7. 7. GAO & others lack understanding of results…<br />…so program effectiveness is questioned and funding attacked.<br />
  8. 8. Compliance is based on a checklist of actions.<br />Public opinion is based on dollars spent.<br />
  9. 9. Compliance is based on a checklist of actions.<br />Public opinion is based on dollars spent.<br />TMDL & stormwater accounting unifies focus on water quality outcomes.<br />
  10. 10. How can we make our TMDLs more effective?<br />
  11. 11. TMDLs effectively…<br />define baselines, goals & milestones.<br />15 Year Goal<br />10 Year Goal<br />5 Year Goal<br />
  12. 12. TMDLs Identify Source Categories with LAs & WLAs<br />Agricultural<br />Atmospheric<br />Stormwater - Municipalities<br />Stormwater - DOT<br />Point Sources<br />
  13. 13. Accounting takes TMDLs one step further…<br /> defines site-scale incremental load reductions – credits<br /> links on-the-ground actions to system-wide goals.<br />
  14. 14. Use load reductions as reporting criteria in NPS grant programs.<br />TMDL Targets<br />NPS Program Goals<br />10 Year Goal<br />5 Year Goal<br />2 Year Goal<br />
  15. 15. Use load reductions as effluent limits in MS4 permits.<br />TMDL Targets<br />NPDES Permit Goals<br />10 Year Goal<br />5 Year Goal<br />2 Year Goal<br />
  16. 16. TMDL & Stormwater accounting enables prioritization of…<br />what to do & where to do it.<br />
  17. 17. what to do.<br />green<br />gray<br />o&m<br />
  18. 18. whereto do it.<br />Prioritized urban catchments based on expected load reduction potential.<br />
  19. 19. TMDL & Stormwater accounting enables coordination between permitted entities.<br />City of South Lake Tahoe<br />CA DOT<br />
  20. 20. Performance-Based Adaptive Management System<br />
  21. 21. Use Models to Leverage Monitoring<br />Model Expected Loading<br />Adopt Improved Models<br />use models to prioritize where & what to implement<br />establish load reduction hypothesis<br />peer review & comment<br />Monitor<br /><ul><li>Targeted
  22. 22. Intensive</li></ul>Improve Models<br />compare modeled to observed results<br />
  23. 23. Is TMDL & stormwater accounting…<br /> worth the additional cost?<br />
  24. 24.
  25. 25. Performance and Cost Effectiveness Increase from TMDL & Stormwater Accounting. <br />TMDL & Stormwater accounting<br />Poorly performing projects<br />
  26. 26. Performance and Cost Effectiveness Increase from TMDL & Stormwater Accounting. <br />TMDL & Stormwater accounting<br />Poorly performing projects<br />
  27. 27. Jeremy Sokulsky, PE, MBA<br />President<br />530-541-2980<br />jsokulsky@enviroincentives.com<br />tmdl&stormwater accounting<br />
