c. If wastes will be discharged into a sewer system or pretreatment system, identify the <br />system and discuss the ability of the system to accept the volume and composition of the <br />wastes. Identify any improvements which will be necessary. <br />20. Ground Water - Potential for Contamination <br />a. Approximate depth (in feet) to ground water; 0 minimum: 90 ft. maximum the average <br />depth is approximately 25 to 40 feet.. <br />b. Describe any of the following site hazards to ground water and also identify them on the <br />site map: sinkholes; shallow limestone formations/karst conditions: soils with high infiltration <br />rates; abandoned or unused wells. Describe measures to avoid or minimize environmental <br />problems due to any of these hazards. <br />There are no known hazards to groundwater on the Site. All unused wells known to be <br />present on the Site or discovered during construction will be abandoned in strict accordance <br />with Minnesota Department of Health regulations during the construction of the project. Only <br />one unique well number is known. <br />c. Identify any toxic or hazardous materials to be used or present on the project site and <br />identify measures to be used to prevent them from contaminating ground water. <br />Currently only small amounts of fertilizes and pesticides are used on the Site. In the future the <br />total volume of use of these chemicals will increase because of increased use of the land. <br />Application of both fertilizers and pesticides will be by licensed, certified applicators following <br />approved management practices for golf courses. <br />21. Solid Wastes; Hazardous Wastes; Storage Tanks <br />a. Describe the types, amounts, and compositions of solid or hazardous wastes to be <br />generated, including animal manures, sludges and ashes. Identify the method and location <br />of disposal. For projects generating municipal solid waste indicate if there will be a source <br />separation plan; list type(s) and how the project will be modified to allow recycling. <br />During construction several of the existing buildings will be razed. Demolition debris will be <br />properly disposed of at an MPCA approved demolition debris landfill. Long term, the only <br />anticipated wastes to be generated by this project are municipal solid wastes. Municipal solid <br />wastes are collected by private haulers on a contract basis and the majority are ultimately <br />burned and converted to elen city at the Hennepin County Waste to Energy facilities in <br />Minneapolis. Ash and other v.i'cab/e residues are then shipped to contract ash landfills. <br />The City of Orono provides a wcokiy curbside recycling program for paper, glass and plastics. <br />No hazardous wastes are generated on the Site and none will be generated during the future <br />use. <br />A spill of petroleum products was reported on the property on November 21, 1990. According <br />to the MPCA project manager, Mr. Hannon, the amount was small because there was no <br />additional information in the MPCA file about the size of the release or if additional work was <br />requested.
