DG'cu.s's soil gramdarit~, and <br />potential for groundwater contamination fi-om wastes or chemicals spread or spilled onto the soils. <br />Discuss any mitigation measures to prevent such contamination. <br /> <br />The Soil Survey of Sherbume County, Minnesota (USDA, 1999) indicates the following soils <br />occur within the project area (Exhibit 9). <br /> <br />Table 19.1.

Soil series mapping indicates <br />slopes range from 0 to 12 percent across the site. <br /> <br />20. Solid Wastes, Hazardous Wastes, and Storage Tanks <br /> <br />Describe ~, pes, amounts and compositions of solid or hazardous ,vastes, including solid animal manure, <br />shtdge and ash, produced during consnxlction and operation, ldentij~y' method and location of disposal. <br />Forprojects generating municipal solid waste, indicate if there is a sot.wce separation plan; describe how <br />the project will be modified for recycling. If hazardous waste is generated, indicate if there is a hazardous <br />waste minimization plan and routine hazardot.ts waste reduction assessments. <br /> <br />Solid waste generation will be typical of mixed-use development. It is not anticipated that the <br />proposed residential development will generate significant amounts of wastes that would be <br />considered "hazardous." According to the Minnesota Office of Environmental Assistance, there <br />are no available statewide, solid waste generation studies for Minnesota. Based on data provided <br />by the California Integrated Waste Management Board <br />(http://www.ciwmb.ca.qov/WasteChar/WasteGenRates/default. htm and SOlid Waste <br />Characterization Study: Results and Final Report, December 1999), solid waste generation for <br />the development is estimated at 830 tons per year. This estimate is detailed in the following <br />table. No animal manure, sludge, or ash generation is anticipated. <br /> <br />Table 20.1.

These estimates are rough approximations based on studies <br />of similar but unrelated developments (Solid Waste Characterization Study: Results and Final <br />Report, California Integrated Waste Management Board, December 1999). <br /> <br />~¥ Westwood Professional Services, Inc.
