Draft North & East Metro Groundwater Management Area Plan 5-3 <br /> L DNR will continue to coordinate studies and work with permitted groundwater users <br /> having potential negative impacts on Valley Creek, Browns Creek,Trout Book and other <br /> trout streams within the GWMA. <br /> c. DNR will develop thresholds to determine negative impacts to basins and wetlands as required <br /> by Minnesota Statutes, sec. 103G.287, subd. 220. <br /> i. DNR will work with USGS, Met Council, Watershed Districts and others to evaluate lakes <br /> and basins in the GWMA for specific susceptibility to changing groundwater levels. <br /> ii. DNR will work with USGS and others to model the total annual volume of water that is <br /> withdrawn from White Bear Lake due to permitted groundwater appropriations. If the <br /> total annual volume withdrawn is greater than one-half acre-foot per acre,then DNR <br /> will work with permittees to adjust their permits. DNR will use the procedures outlined <br /> in Minnesota Rules, part 6110.0740 to resolve any water use conflicts that are identified <br /> by this analysis. <br /> iii. DNR will set a protective elevation for White Bear Lake using the considerations listed in <br /> Minn. Stat. 103G.285,subd. 3. <br /> iv. DNR will work with BWSR, USFWS, Watershed Districts and others to determine limits <br /> on withdrawals from wetlands in the GWMA due to groundwater appropriations as <br /> guided by statute and rule. <br /> d. DNR will manage appropriations to meet the sustainability thresholds. <br /> 3. DNR groundwater appropriation permits will integrate sustainability limits,individual and <br /> cumulative permit analysis, and will include evaluation of existing permits within the GWMA. <br /> a. DNR will evaluate each new permit application individually, as well as in conjunction with other <br /> permits in the related aquifer systems to address challenges of cumulative impacts. <br /> b. DNR will complete a review of all existing permits in the GWMA within 5 years,and if necessary <br /> adjust permits to achieve sustainable groundwater use". <br /> c. Where needed, and in accordance with statutory requirements, DNR will limit current and <br /> future appropriation S.22 <br /> 4. DNR will improve communication on the status of Objective I (aquifers, ecosystems,surface <br /> waters)in the GWMA. <br /> 20 DNR has not determined negative impact limits for wetlands and lakes. However,we recognize that this is a vital <br /> component of assessing sustainability of aquifers and surface water features such as lakes and wetlands. DNR is <br /> committed to working with stakeholders as these negative impact limits are established. <br /> 21 DNR has not determined the detailed steps and timeline for how we will evaluate and implement any necessary <br /> changes to existing permits. However,we recognize that this is a vital component of GWMA planning,and we are <br /> committed to working with permittees as we develop that process. <br /> 22 DNR has not determined the detailed steps and timeline for how we will evaluate and implement any necessary <br /> changes to existing permits.
