open water to 20 feet deep. Additional information about groundwater can be found in <br /> Appendix C. <br /> b. Describe effects from project activities on water resources and measures to minimize or <br /> mitigate the effects in Item b.i. through Item b.iv. below. <br /> i. Wastewater— For each of the following, describe the sources, quantities and <br /> composition of all sanitary, municipal/domestic and industrial wastewater <br /> produced or treated at the site. <br /> 1) If the wastewater discharge is to a publicly owned treatment facility, identify <br /> any pretreatment measures and the ability of the facility to handle the added <br /> water and waste loadings, including any effects on, or required expansion of, <br /> municipal wastewater infrastructure. <br /> 2) If the wastewater discharge is to a subsurface sewage treatment systems <br /> (SSTS), describe the system used, the design flow, and suitability of site <br /> conditions for such a system. <br /> 3) If the wastewater discharge is to surface water, identify the wastewater <br /> treatment methods and identify discharge points and proposed effluent <br /> limitations to mitigate impacts. Discuss any effects to surface or groundwater <br /> from wastewater discharges. <br /> Updated analysis on the wastewater system can be found in Appendix D. <br /> ii. Stormwater— Describe the quantity and quality of stormwater runoff at the site <br /> prior to and post construction. Include the routes and receiving water bodies for <br /> runoff from the site (major downstream water bodies as well as the immediate <br /> receiving waters). Discuss any environmental effects from stormwater discharges. <br /> Describe stormwater pollution prevention plans including temporary and <br /> permanent runoff controls and potential BMP site locations to manage or treat <br /> stormwater runoff. Identify specific erosion control, sedimentation control or <br /> stabilization measures to address soil limitations during and after project <br /> construction. <br /> Updated analysis on stormwater can be found in Appendix B. <br /> iii. Water appropriation — Describe if the project proposes to appropriate surface or <br /> groundwater(including dewatering). Describe the source, quantity, duration, use, <br /> and purpose of the water use and if a DNR water appropriation permit is required. <br /> Describe any well abandonment. If connecting to an existing municipal water <br /> supply, identify the wells to be used as a water source and any effects on, or <br /> required expansion of, municipal water infrastructure. Discuss environmental <br /> effects from water appropriation, including an assessment of the water resources <br /> available for appropriation. Identify any measures to avoid, minimize, or mitigate <br /> environmental effects from the water appropriation. <br /> Updated analysis on water system impacts can be found in Appendix C. <br /> 1-35E Corridor AUAR Update <br /> June 6,2025 <br /> Page 7 <br /> Page 63 of 240 <br />
