Recent soil boring logs from 1994 and 1999 found ground water levels on the site to range from 4.5 to 15 feet below the surface. Based on the soil borings, the average water table elevation was 9.4 feet below ground, at an average elevation of 90 I MSL. The ordinary high water level (OHWL) ofDNR Wetland SOW is 902 MSL, also indicative of the water table elevation. The described soil borings were to a depth of20 feet below the surface, and no bedrock was encountered, According to Mossier and Cleland, depth to bedrock in the area is approximately 100 feet (Depth to Bedrock Map, County Atlas Series, Atlas C-7, Plate 5 in the Geologic Atlas, Ramsey County, Minnesota, University of Minnesota, St. Paul, 1992). The described soil boring logs are available for review upon request. 20. Solid wastes, hazardous wastes, storage tanks a. Describe types, amounts and compositions of solid or hazardous wastes, including solid animal manure, sludge and ash, produced during construction and operation. Identify method and location of disposal. For projects generating municipal solid waste, indicate if there is a source separation plan; describe how the project will be modified for recycling. If hazardous waste is generated, indicate if there is a hazardous waste minimization plan and routine hazardous waste reduction assessments. ' b, Identify any toxic or hazardous materials to be used or present at the site and identify measures to be used to prevent them from contaminating groundwater, If the use of toxic or hazardous materials will lead to a regulated waste, discharge or emission, discuss any alternatives considered to minimize or eliminate the waste, discharge or emission. The proposed types of site users would generate no wastes that are considered "hazardous". Types of solid wastes generated would include those common to office uses such as paper, cardboard, newspaper, food wastes, metal cans, film plastics, glass, etc. Using data from a 1993 study of wastes generated by various types of businesses (Los Angeles AB 939 Plan: Commercial Generator Strategies, 1993), estimated quantities of solid wastes that will be disposed are as follows: Type of Sample A vg. Amount Proposed Estimated Amount of Business Size of Solid Waste Number of Solid Waste to be Disposed Businesses Disposed (tons per year) (tons per year) (a) (b) (a) x (b) Office 1,000 137 8 1,096 Total 1,096 The following table shows typical recyclable materials generated by 2 types of businesses proposed for the site and the percentage of each business' waste stream that is comprised of those materials.
