12. Contamination/Hazardous Materials/Wastes: a. Pre-project site conditions - Describe existing contamination or potential environmental hazards on or in close proximity to the project site such as soil or ground water contamination, abandoned dumps, closed landfills, existing or abandoned storage tanks, and hazardous liquid or gas pipelines. Discuss any potential environmental effects from pre- project site conditions that would be caused or exacerbated by project construction and operation. Identify measures to avoid, minimize or mitigate adverse effects from existing contamination or potential environmental hazards. Include development of a Contingency Plan or Response Action Plan. Past land use of the Site has been rural residential. There are no known existing soil or groundwater contamination hazards at the Site. The Elk River landfill is located to the west of the Site and is equipped with a liner, a leachate collection system, and a groundwater monitoring system. The Elk River Landfill has taken corrective actions for groundwater contamination associated with the old unlined portion of the landfill to ensure that no groundwater contamination leaves the landfill boundaries.13 The Site is located upgradient of the landfill and the Elk River Landfill EIS concluded that the potential impact to downgradient receptors is low and that it does not appear that there is a potential impact to groundwater or surface water from leachate generated at the landfill. b. Project related generation/storage of solid wastes - Describe solid wastes generated/stored during construction and/or operation of the project. Indicate method of disposal. Discuss potential environmental effects from solid waste handling, storage and disposal. Identify measures to avoid, minimize or mitigate adverse effects from the generation/storage of solid waste including source reduction and recycling. Solid waste generation at the Site is limited to small quantities of solid waste generated from employees. Dumpsters will be used on-site during active operations and a hauling service contracted with to haul the solid waste to a licensed disposal facility. c. Project related use/storage of hazardous materials - Describe chemicals/hazardous materials used/stored during construction and/or operation of the project including method of storage. Indicate the number, location and size of any above or below ground tanks to store petroleum or other materials. Discuss potential environmental effects from accidental spill or release of hazardous materials. Identify measures to avoid, minimize or mitigate adverse effects from the use/storage of chemicals/hazardous materials including source reduction and recycling. Include development of a spill prevention plan. There is no storage of hazardous materials at the Site. Very small quantities of hazardous materials may be brought to the Site when performing routine maintenance of on-site equipment. These materials are considered Materials of Trade and are carried on the service truck that comes to the Site to perform the routine maintenance.
