MMSD Perspective - Susan Anthony

  1. 1. SWWT Phosphorus Forum Proposed NR 217 May 27, 2010 Milwaukee Metropolitan Sewerage District Perspective
  2. 2. Background <ul><li>DNR Advisory Committee Convened February 2008 </li></ul><ul><li>November 23, 2009: Seven Environmental Groups file Notice of Intent to sue US EPA Administrator for failure to promulgate numeric criteria for the State of Wisconsin </li></ul><ul><li>Clean Water Action Council of Northeastern Wisconsin; Environmental Law & Policy Center; Midwest Environmental Advocates; Milwaukee Riverkeeper; Prairie Rivers Network; River Alliance of Wisconsin; Sierra Club; Wisconsin Wildlife Federation </li></ul><ul><li>Similar action was taken in 2009 to compel US EPA to issue phosphorus Water Quality Standards in Florida </li></ul>
  3. 3. Background <ul><li>January 7, 2010 letter to DNR Secretary Matthew Frank and USEPA Administrator Lisa Jackson </li></ul><ul><li>From MMSD, Green Bay Met, Madison Met, and Municipal Environmental Group </li></ul><ul><li>Support of WDNR in its efforts to develop numeric nutrient criteria for Wisconsin </li></ul><ul><li>Including changes to NR 151 relating to non-point sources, particularly agricultural sources </li></ul>
  4. 4. Anticipated Rule Adoption Schedule <ul><li>April 2010 Public Hearings Held </li></ul><ul><li>June 2010 DNR Board Meeting: Approval of New Rules Expected </li></ul><ul><li>Submit to Legislature for Review before September 1, 2010 </li></ul><ul><li>Otherwise, legislative review does not occur until 2011 under sec. 227.19(2) Wis. Stats. </li></ul>
  5. 5. Current DNR Proposed Rules <ul><li>NR 151 rules address agricultural, construction and urban runoff </li></ul><ul><li>NR 102 rules establish in-stream water quality numeric standards </li></ul><ul><li>NR 217 rules establish implementation methods for point sources; including adaptive implementation approach and variance procedures </li></ul>
  6. 6. What is MMSD’s current performance on phosphorus removal? <ul><li>Current phosphorus limit for both water reclamation plants is 1.0 mg/liter </li></ul><ul><li>Both plants consistently meet this limitation </li></ul><ul><li>Both plants achieve a high level of removal </li></ul><ul><li>On average, between 87% and 93 % reduction from influent loads </li></ul>
  7. 7. Jones Island Monthly P Loads
  8. 8. South Shore Monthly P Loads
  9. 9. Comparison of JI and SS effluent P
  10. 10. South Shore P Removal Efficiency
  11. 11. Jones Island P Removal Efficiency
  12. 12. What do the new rules mean to MMSD and watersheds? <ul><li>For South Shore Water Reclamation Facility: New numeric phosphorus water quality standard for Lake Michigan is 0.007 mg/liter (7 ug/L) </li></ul><ul><li>For Jones Island Water Reclamation Facility: New numeric water quality standard for the Outer Harbor is 0.1 mg/liter (100 ug/L) </li></ul>
  13. 13. Estimated Costs <ul><li>MMSD Estimate: Based on Costs developed in MMSD 2020 Facilities Plan </li></ul><ul><li>$500 million: Filtration Technology at both plants (capital cost only; O&M additional) </li></ul><ul><li>Does not include land acquisition costs </li></ul><ul><li>Statewide Estimate: </li></ul><ul><ul><li>municipal filtration systems </li></ul></ul><ul><ul><li>ranges from $1.3 billion to $4.3 billion </li></ul></ul>
  14. 14. How best to meet these new standards? <ul><li>Standards have not been subject of much debate </li></ul><ul><li>IMPLEMENTATION IS FOCUS </li></ul><ul><li>WATERSHED APPROACH IS KEY </li></ul><ul><li>First we need to look at where the phosphorus is coming from in our watersheds. </li></ul><ul><li>This will vary from watershed to watershed. </li></ul>
  15. 15. Where is the phosphorus coming from in our watersheds? <ul><li>In MMSD service area we are fortunate to have answers to this question </li></ul><ul><li>MMSD 2020 Facility Plan </li></ul><ul><li>SEWRPC 208 Plan Update </li></ul>
  16. 18. IMPLEMENTATION GOAL: Nonpoint and urban storm water should be addressed first <ul><li>2020 Facility Plan and SEWRPC 208 report clearly demonstrate that nonpoint and urban storm water contribution are significant sources of phosphorus </li></ul><ul><li>Nonpoint and stormwater can be more cost effectively controlled than end of pipe treatment, i.e., filtration </li></ul><ul><li>Cost per pound of non-point P reduction estimated to be on order of 10% of filtration costs </li></ul>
  17. 19. IMPLEMENTATION APPROACH <ul><li>Support DNR revised runoff control requirements in NR 151 </li></ul><ul><li>Support DNR revisions to P water quality standards </li></ul><ul><li>Support new concept in NR 217 which incorporates the watershed approach </li></ul><ul><li>Called Adaptive Management Option </li></ul>
  18. 20. NEW CONCEPT: Adaptive Management Option <ul><li>During the Advisory Committee process, MMSD and other municipal treatment plants urged DNR to consider an adaptive implementation approach </li></ul><ul><li>DNR has incorporated this concept into the proposed Rule at NR 217.17(4) </li></ul>
  19. 21. What is Adaptive Management Option? <ul><li>Stepped process under which point sources agree to achieve lower P limit, monitor in stream water quality, develop restoration plan and facilitate implementation of BMP’s for upstream sources </li></ul><ul><li>Up to three permit terms are allowed to achieve in stream P water quality standard </li></ul>
  20. 22. Purposes of Adaptive Management Option <ul><li>To create incentives for treatment plants (and other point sources) to implement most effective P controls by allowing them to search the watershed for the best options; probably Best Management Practices for upstream nonpoint and urban storm water sources </li></ul><ul><ul><li> </li></ul></ul>
  21. 23. Purposes of Adaptive Management Option <ul><li>To require in stream water quality monitoring to measure impacts of those controls </li></ul><ul><li>To allow time for P reduction actions to occur: </li></ul><ul><ul><li>Phosphate detergent ban </li></ul></ul><ul><ul><li>Phosphorus fertilizer ban </li></ul></ul><ul><ul><li>Municipal storm water controls </li></ul></ul>
  22. 24. Example of how Adaptive Management Option can work <ul><li>Municipal treatment plant “opts in” to the Adaptive Management Option in its permit reissuance application </li></ul><ul><li>Accepts interim limitation of 0.6 mg/l as required by rule (note: this is lower than current applicable limit of 1.0 mg/l) </li></ul><ul><li>During 5 year permit term, treatment plant agrees to monitor in stream water quality; locates P sources upstream and negotiates (and contributes to cost) BMP’s aimed at P reductions. </li></ul>
  23. 25. How Adaptive Management Option Can Work <ul><li>At end of 5 year permit term, if P water quality standard has not been met, POTW must accept permit limitation of 0.5 mg/l for next 5 year term of permit; </li></ul><ul><li>POTW must monitor in stream water quality and continue to seek in stream P reductions </li></ul><ul><li>At end of second 5 year term in stream water quality is evaluated; if met, POTW has succeeded in implementing a watershed solution and faces no further reduction in P discharge limitations </li></ul><ul><li>If in stream water quality standard not met, POTW faces limits calculated under NR 217.13, possibly leading to filtration technology requirements </li></ul>
  24. 26. Adaptive Management Concept
  25. 27. Why we support Adaptive Management Option <ul><li>Best use of financial resources </li></ul><ul><li>Watershed based approach to solving the P problem </li></ul><ul><li>Creates incentives for POTW’s to fund phosphorus reductions through agricultural or stormwater best management practices </li></ul>
  26. 28. Why we support Adaptive Management Option <ul><li>Under current law, agricultural sources are not required to comply with NR 151 unless state funding is available </li></ul><ul><li>Science has defined what should work, i.e., agricultural “no till” zones or buffers, other BMP’s; Option affords POTW’s ability to purchase these BMP’s to avoid higher costs. </li></ul>
  27. 29. Why we support Adaptive Management Option <ul><li>Process based on in stream water quality data </li></ul><ul><li>Water quality improvement should be demonstrated </li></ul>
  28. 30. MMSD Perspective on NR 217 <ul><li>Questions or Comments? </li></ul>
