6. David P. Lusch, Ph.D. lusch@msu.edu 6 / 26 Water Withdrawal Assessment Tool –User enters the location for a new groundwater withdrawal. –GIS software determines the “home” catchment. –If the proposed well is in bedrock, the bedrock type for the catchment is identified from the GIS database.

8. David P. Lusch, Ph.D. lusch@msu.edu 8 / 26 Water Withdrawal Assessment Tool –From the GIS database, the aquifer properties of the catchment and whether it is a Great Lake shoreline catchment are identified. –Nearest-neighbor stream segments to the proposed withdrawal site are identified. –Distances from the proposed well to the nearest stream segments are computed. Michigan’s Water Withdrawal Assessment Process for Planning and Watershed Management

9. David P. Lusch, Ph.D. lusch@msu.edu 9 / 26 Water Withdrawal Assessment Tool –Groundwater flow model runs for each stream segment using aquifer properties for the catchment containing the well and the distances to the nearest stream segments. For continuous pumping, the solution is evaluated after 5 years of simulation. Michigan’s Water Withdrawal Assessment Process for Planning and Watershed Management

10. David P. Lusch, Ph.D. lusch@msu.edu 10 / 26 Water Withdrawal Assessment Tool –For intermittent pumping, the superposition equation is used to compute the maximum streamflow depletion during the 5-year evaluation period. –The streamflow depletion is apportioned to the neighboring stream segments using inverse distance weighting. –Estimated streamflow depletions are compared to the “available” streamflows and determination is provided to the user.

18. David P. Lusch, Ph.D. lusch@msu.edu 18 / 26 MDEQ required notifications –If the MDEQ receives a registration or issues a permit for a zone B or zone C withdrawal, it shall place a notice on the department's website and notify by e-mail all of the following that have requested an e-mail notification: Conservation districts Regional planning agencies Watershed management planning committees Storm water committees established under part 31 Chief elected officials of local units of government Community supplies owned by political subdivisions All Water Users Committees in the vicinity Michigan’s Water Withdrawal Assessment Process for Planning and Watershed Management

19. David P. Lusch, Ph.D. lusch@msu.edu 19 / 26 Water users committees –All persons making LQWs within a watershed are encouraged to establish a water users committee to evaluate the status of current water resources, water use, and trends in water use within the watershed and to assist in long-term water resources planning. –A water users committee may be composed of all registrants, permit holders, and local government officials within the watershed. Michigan’s Water Withdrawal Assessment Process for Planning and Watershed Management

20. David P. Lusch, Ph.D. lusch@msu.edu 20 / 26 Water users committees –Upon establishment of a water users committee, a participating local government official may create an ad hoc subcommittee of residents of that local unit of government to provide that local government official with information and advice on water resources, water use, and trends in water use within the local unit of government.

21. David P. Lusch, Ph.D. lusch@msu.edu 21 / 26 Water resources assessment and education committees –The notified entities may form a water resources assessment and education committee in order to: assess trends in water use in the vicinity of the withdrawal educate water users –The MDEQ shall assist in the formation of water resources assessment and education committees and may provide them with technical information regarding water use and capacity within their vicinity, aggregated at the stream reach level.

22. David P. Lusch, Ph.D. lusch@msu.edu 22 / 26 Water resources assessment and education committees –Committee meetings shall be open to the general public. –Water resources assessment and education committees may provide educational materials and recommendations regarding any of the following: Long-term water resources planning Use of conservation measures Drought management activities Other topics related to water use as identified by the committee Michigan’s Water Withdrawal Assessment Process for Planning and Watershed Management

23. David P. Lusch, Ph.D. lusch@msu.edu 23 / 26 Regulatory “teeth” –If the MDEQ determines by reasonable, scientifically- based evidence that ARIs are occurring or are likely to occur from one or more LQWs, they shall: notify the water users committee in the watershed, or convene a meeting of all registrants and permit holders within the watershed –MDEQ shall attempt to facilitate an agreement on voluntary measures that would prevent adverse resource impacts. Michigan’s Water Withdrawal Assessment Process for Planning and Watershed Management

24. David P. Lusch, Ph.D. lusch@msu.edu 24 / 26 Regulatory “teeth” –If after 30 days the registrants and permit holders are not able to voluntarily agree to measures that would prevent adverse resource impacts, the MDEQ may propose a solution that the department believes would equitably resolve the situation and prevent adverse resource impacts. –The recommended solution is not binding on any of the parties.

25. David P. Lusch, Ph.D. lusch@msu.edu 25 / 26 Regulatory “teeth” –The Director of the MDEQ may order permit holders to immediately restrict their withdrawals (for up to 60 continuous days) if the Agency determines by clear and convincing scientific evidence that there is a substantial and imminent threat that these withdrawals are causing or are likely to cause an adverse resource impact. –Permit holders include: New or increased LQW  2 million gpd (1,389 gpm) New or increased LQW  1 million gpd (694 gpm) that a site-specific review determined is a zone C withdrawal LQWs holding a permit under the Safe Drinking Water Act (PA 399, 1976) Michigan’s Water Withdrawal Assessment Process for Planning and Watershed Management
