Short-term temporary construction dewatering of surface or ground waters may be required at <br />the time of construction (depending on current field conditions) to facilitate construction activities <br />(e.g., utility installation, etc.). If dewatering is anticipated to exceed 10,000 gallons per day or <br />1,000,000 gallons per year, the contractor will be required to obtain a Water Appropriations Permit <br />from the Department of Natural Resources (MnDNR) Division of Waters prior to initiating such <br />activities. Measures to avoid, minimize, or mitigate the environmental effects from construction <br />related to dewatering are unknown at this time, and therefore will be determined when developing <br />the dewatering plan as required by a Stormwater Pollution Prevention Plan amendment of the <br />NPDES Construction Stormwater Permit. <br />iv. Surface Waters <br />a) Wetlands - Describe any anticipated physical effects or alterations to wetland <br />features such as draining, filling, permanent inundation, dredging and vegetative <br />removal. Discuss direct and indirect environmental effects from physical modification <br />of wetlands, including the anticipated effects that any proposed wetland alterations <br />may have to the host watershed, taking into consideration how current Minnesota <br />climate trends and anticipated climate change in the general location of the project <br />may influence the effects. Identify measures to avoid (e.g., available alternatives that <br />were considered), minimize, or mitigate environmental effects to wetlands. Discuss <br />whether any required compensatory wetland mitigation for unavoidable wetland <br />impacts will occur in the same minor or major watershed and identify those probable <br />locations. <br />Approximately 44 acres of wetland are located throughout the Project site. The site was <br />field delineated in 2022 by Kjolhaug Environmental Services. <br />Wetland impacts were avoided to the extent possible during the preliminary design phase <br />of the overall site plan (Appendix B). The final design will attempt to avoid and/or minimize <br />impacts to the extent possible. Should unavoidable impacts remain, the proper permitting <br />processes will be followed in accordance with the Minnesota Wetland Conservation Act <br />(WCA) and/or Section 404 of the Clean Water Act as applicable. This process would involve <br />applying for a replacement plan potentially requiring compensatory mitigation. The area <br />of wetland impact and jurisdictional status of the wetlands will be determined by the <br />proper governmental agency during the permitting process following conclusion of the <br />environmental review process. <br />b) Other surface waters- Describe any anticipated physical effects or alterations to <br />surface water features (lakes, streams, ponds, intermittent channels, county/judicial <br />ditches) such as draining, filling, permanent inundation, dredging, diking, stream <br />diversion, impoundment, aquatic plant removal and riparian alteration. Discuss direct <br />and indirect environmental effects from physical modification of water features, <br />taking into consideration how current Minnesota climate trends and anticipated <br />climate change in the general location of the project may influence the effects. <br />Identify measures to avoid, minimize, or mitigate environmental effects to surface <br />water features, including in -water Best Management Practices that are proposed to <br />avoid or minimize turbidity/sedimentation while physically altering the water <br />features. Discuss how the project will change the number or type of watercraft on <br />any water body, including current and projected watercraft usage. <br />Page 18 <br />
