This is not a silica sand project, therefore no hydrogeological investigation assessment of the potential groundwater and surface water effects to geologic conditions is required. NOTE: For silica sand projects, the EAW must include a hydrogeological investigation assessing the potential groundwater and surface water effects and geologic conditions that could create an increased risk of potentially significant effects on groundwater and surface water. Descriptions of water resources and potential effects from the project in EAW Item 11 must be consistent with the geology, soils and topography/land forms and potential effects described in EAW Item 10. 11. Water resources: a. Describe surface water and groundwater features on or near the site in a.i. and a.ii. below. i. Surface water - lakes, streams, wetlands, intermittent channels, and county/judicial ditches. Include any special designations such as public waters, trout stream/lake, wildlife lakes, migratory waterfowl feeding/resting lake, and outstanding resource value water. Include water quality impairments or special designations listed on the current MPCA 303d Impaired Waters List that are within 1 mile of the project. Include DNR Public Waters Inventory number(s), if any. The following resources were reviewed to identify surface water resources within a 1 -mile radius of the project area: • USGS Topographic Quad Maps (Figure 2, Appendix A) • National Wetlands Inventory (Figure 12, Appendix A) • Minnesota Department of Natural Resources Public Water Inventory (Figure 13, Appendix A) A review of the National Wetlands Inventory (N WI) map shows multiple wetlands and wetland complexes within and adjacent to the project site. The Minnesota Department of natural Resources Public Water Inventory (PWI) map does not identify any public waters on the project site. Within a one -mile radius, the PWI does identify one unnamed public waterbasin northeast and one unnamed public waterbasin south of the project site. One public watercourse, Trott Brook is located east and one unnamed stream is located west of the project site, within a one -mile radius. There are no MPCA 303d Impaired Waters within I mile of the project site. Surface water resources located within the project site were identified and delineated by Anderson Engineering of Minnesota, LLC in the spring of 2016. A total of eleven wetlands were delineated, one of which is connected to an abandoned judicial ditch that extends off-site to the northeast. The wetland boundaries and types were field reviewed by the Technical Evaluation Panel and subsequently approved by the City of Elk River as the Local Government Unit responsible for implementing the Minnesota Wetland Conservation Act, as documented in a Notice of Decision dated May 16, 2016 (included in Appendix B). Wetlands located on other properties to be utilized under the parking agreement were previously delineated under applicable requirements for gravel mining. The wetland and boundary type approval for the delineation completed on the property located directly north of ERX Motor Parks is documented in the Notice of Decision dated October 13, 2013 (included in Appendix B).
