channels, county/judicial ditches) such as draining, filling, permanent <br /> inundation, dredging, diking, stream diversion, impoundment, aquatic plant <br /> removal, and riparian alteration. Discuss direct and indirect environmental <br /> effects from physical modification of water features, taking into <br /> consideration how current Minnesota climate trends and anticipated climate <br /> change in the general location of the project may influence the effects. <br /> Identify measures to avoid, minimize, or mitigate environmental effects to <br /> surface water features, including in-water Best Management Practices that <br /> are proposed to avoid or minimize turbidity/sedimentation while physically <br /> altering the water features. Discuss how the project will change the number <br /> or type of watercraft on any water body, including current and projected <br /> watercraft usage. <br /> No alternations to other surface waters are anticipated. <br /> 13.Contamination/Hazardous Materials/Wastes <br /> a. Pre-project Site Conditions— Describe existing contamination or potential <br /> environmental hazards on or in close proximity to the project site, such as soil or <br /> groundwater contamination, abandoned dumps, closed landfills, existing or <br /> abandoned storage tanks, and hazardous liquid or gas pipelines. Discuss any potential <br /> environmental effects from pre-project site conditions that would be caused or <br /> exacerbated by project construction and operation. Identify measures to avoid, <br /> minimize, or mitigate adverse effects from existing contamination or potential <br /> environmental hazards. Include development of a Contingency Plan or Response <br /> Action Plan. <br /> MPCA's What's In My Neighborhood (WIMN) database was reviewed to determine if any <br /> known contaminated properties or potential environmental hazards are located on the <br /> project site or within 150 feet of the project site. The database includes one site within the <br /> project site, and one site within 150 feet (see Table 9 and Figure 11). <br /> Using the following criteria established by the Minnesota Department of Transportation <br /> (MnDOT), the sites were classified into high, medium, and low risk sites: <br /> • High risk: In general, sites with high environmental risks are properties that have <br /> documented releases of chemicals or hazardous or regulated substances (e.g., active <br /> and inactive state and federal cleanup sites, active and inactive dump sites, and active <br /> leaking underground storage tank sites), strong evidence of contamination (e.g., soil <br /> staining, stressed vegetation), or storage of large volumes of petroleum or other <br /> chemicals (e.g., bulk storage tank facilities). <br /> • Medium risk: Sites of medium environmental risk are properties where smaller <br /> volumes of petroleum, chemicals, or hazardous materials are frequently stored and <br /> used (e.g., registered underground and aboveground storage tanks, vehicle repair <br /> facilities, metal working shops), but at which no evidence of spills or releases exists, <br /> or properties with documented releases that have been "closed" (signifying no <br /> further cleanup actions deemed necessary) by the MPCA. Closed sites, such as closed <br /> leaking underground storage tank sites, are considered medium risks because <br /> Haviland Fields EAW 17 September 2023 <br />
