1. Metropolitan Council Metropolitan Council Environment Committee Master Water Supply Plan February 10, 2009 Keith Buttleman Assistant General Manager, Environmental Quality Assurance Christopher Elvrum Manager, Water Supply Planning

2. Purpose • Draft Master Water Supply Plan • Public review comments • Master Plan completion schedule

3. Master Plan Conclusions • Overall supplies are regionally adequate • Some water supply issues will occur using traditional sources • Options available to address potential issues • Early identification of issues critical • Ongoing assessment will guide sustainable water use choices

4. Goal and Principles Goal: Ensure a sustainable water supply for current and future generations. Principles • Water supply integral component of planning • Regional context for local decisions • All hydrologic systems considered • Water quality important • Interjurisdictional cooperation viable option • Cost-effectiveness considered • Wise use critical

5. Availability Analysis Groundwater recharge Population forecasts Contamination Conservation Water use Surface Water Evaluation Climate Land use Aquifer analysis Water Supply Availability Analysis Issue Identification METROPOLITAN AREA WATER SUPPLY MASTER PLAN Ongoing Evaluation

6. Unconsolidated Franconia St. Peter Ironton-Galesville Prairie du Chien Eau Claire Jordan Mt. Simon St. Lawrence Metro Model 2 • 4,913 miles2 • Includes entire metro • 9 layers

7. Model Questions • Are supplies available where we need them? • Will pumping harm: • neighboring wells • natural resources • the aquifer • How will climate and land use affect future availability?

8. Scope and Assumptions • Planning horizons: 2030, 2050 • Municipal water use drives water demand growth • Non-municipal demand included; no change forecasted • Current sources used for future demand whenever possible

9. Water Supply Development Issues • Significant decline in aquifers • Well interference • Impacts on surface waters • Significant uncertainty regarding aquifer extent and productivity • Groundwater contamination and vulnerability to contamination

10. DRAFT

11. DRAFT

12. Reporting Results: Community Water Supply Profiles Current and projected water use Current Sources Available Sources Issues that need to be addressed Potential impact to surface waters

13. Issue Responses Issue: Potential impact to surface waters Threshold >1m predicted decline in surficial aquifer by 2030 Response • Develop resource protection thresholds • Daily measurements at wells and resource

14. Issue Responses • Development of resource protection thresholds • Increased monitoring and data collection • Evaluation of supply alternatives • Increased conservation • Limit withdrawals - Use alternative source is an option

15. DRAFT

16. Components of the Plan • Report • Community Profiles • Issue Responses • Conservation Toolbox • Water Supply Make-A-Map Application

18. Public Commenters • Public meetings • 46 attendees from: • 10 cities and townships • counties, • DNR, MDH, EQB, • consultants, non-profits • Metro Cities (AMM), and • Representative Paul Gardner • 4 Metropolitan Area Water Supply Advisory Committee Members • Letters/emails • Total of 59 commenters

19. Comments • General Comments • Metro Model 2 • Integrating Water Supply with Comprehensive Planning • Development of community Profiles and Issue Responses • Updating the Master Plan • Surface water and Stormwater

20. General Comments • General support • How does the plan meet the statutory requirements • What are recommendations

21. Metro Model 2 • Model should be recalibrated prior to publication • What were the methods and measures used to ensure the soundness of the Model

22. Integrating Water Supply with Comprehensive Planning • Support/encourage integration with other comp planning • Do not make water supply a metropolitan system

23. Community Profiles and Issue Responses • How were the forecasts responses developed • Do not introduce requirements (issue responses) without statutory authority • How were local studies considered • What is the reasonableness test for responses • How will the Master Plan affect non-municipal water appropriators

24. Implementing the Master Plan • What will the role of the Met Council and DNR be in implementing the plan • How will existing plans and permits be affected • How will the plan be updated • How will local studies be incorporated

25. Surface Water and Stormwater • Plan focuses on groundwater when 1/3 of population uses surface water • Management of surface water source outside jurisdiction • Support stormwater management activities that recharge groundwater • Map soil contamination to evaluate recharge areas

26. Comment Responses • Model Recalibration • Add information/clarify plan text • Technical analysis • Integration with Comprehensive Planning • Permitting process • Plan implementation • Relationship to surface water and stormwater management

27. Next Steps • Revise Plan – January/February • Update Metro Model 2 – January/February • Update profiles – February/March • Final Advisory Committee Review – March 26 • DNR/Met Council Approval – April/May
