Item-by-item guidance Chapter <br /> Environmental effects from water appropriation should focus on the ability of the water source to supply <br /> the needed water(drawdown) and the effects to surface water features that are dependent on groundwater. <br /> Groundwater appropriations need to consider their effect on groundwater dependent features such as <br /> calcareous fens, springs, seeps, and trout streams. These groundwater dependent features can be affected <br /> by water appropriations as far away as ten miles depending on the aquifer proposed for groundwater <br /> appropriation.Because of this potential,the proposer or RGU should contact the DNR to determine if a <br /> pump test should be conducted as part of the EAW data submittal. <br /> Legislation in 2013 created new requirements for EAWs. When an EAW is required for a project with the <br /> potential to require a groundwater appropriation permit from the commissioner of natural resources,the <br /> EAW must include"an assessment of the water resources available for appropriation." This subitem <br /> regarding water appropriation must describe how water availability was determined. <br /> If a dewatering appropriation is proposed,include a description of proposed treatment of any dewatering <br /> discharge in response to EAW Item I l.b.i.Wastewater. <br /> You must have a licensed well contractor and a permit from MDH or the local board of health with <br /> delegated authority. Before the construction of any new wells,including monitoring wells and <br /> dewatering wells,consult the Well Management Program of MDH for more information about wells and <br /> well construction requirements. <br /> Additional Resources: <br /> • MDH Well Management Program http://www.health.state.mn.us/divs/eh/wells/ <br /> If the project requires the creation,connection or a change to public water supply,it is important to <br /> identify wells that will be used as water sources. Plans for the creation,connection or changes to a public <br /> water supply may need to be reviewed and approved by MDH. Contact the department's public water <br /> supply program for more information. <br /> iv. Surface Waters <br /> a) Wetland alterations <br /> Wetlands in Minnesota are regulated under state or federal permit programs. Therefore,proposed <br /> modifications of all wetlands should be discussed.Wetlands should be identified as either"public <br /> waters wetlands,"which are subject to DNR regulation,or wetlands regulated under the Minnesota <br /> Wetland Conservation Act. <br /> Additional Resources: <br /> • Public Waters Permit Program information is available at DNR regional or area hydrologist offices or <br /> online at: http://www.dnr.state.mn.us/waters/watenugmt_section/pwpermits/requirements.html <br /> • Wetland Conservation Act(Minnesota Rules Chapter 8420)information is available from the county soil <br /> and water conservation district office or online at: http://www.bwsr.state.mn.us/wetlands/regulation.html <br /> Environmental Quality Board EAW Guidelines—October 2013 28 <br />
