3. PLAN OF OPERATION FOR THE SITE: <br /> <br /> The mining will remain the same as that of the existing operation. The <br />gravel is removed from the bank by use of front end loaders to an approximate <br />elevation of 965 feet. No explosives are being used at this site. Gravel is not <br />being excavated below water at this time, however gravel of sufficient quality <br />may be excavated to the water table. The raw gravel is crushed and screened in <br />an area close to the excavation bank. The steep slopes here help to isolate the <br />noise of the operation. After crushing and/or screening, the various products are <br />conveyed to stockpiles until they are loaded onto trucks for delivery offsite by the <br />material licensee. <br /> <br />Generally, the mining will continue to the south where it adjoins the Tiller <br />Corporation property. The interim reclamation/rehabilitation portion of this <br />property plan is the utilization of this mined space as a licensed/permitted mixed <br />municipal solid waste sanitary landfill. (See Site Operations Map, Page 6B) <br /> <br />The shop facility is owned by Elk River Landfill, Inc., and supports both Elk River <br />Landfills' operation as well as Straightlines' mining activity. This activity also <br />includes equipment maintenance and repair as well as equipment storage for <br />both companies. <br /> <br />PERMITS AND LICENSE SECTION: <br /> <br />A. DRAINAGE AND WATER QUALITY: <br /> <br /> Because Elk River Landfill, inc. owns the property, it is Elk River <br />Landfill's obligation to maintain the appropriate NPDES permits. Drainage is <br />contained on site. Runoff is managed by being directed to Iow areas of the pit <br />where sediments are removed and the water infiltrates the soil. This plan <br />complies with the requirements of ERL's Storm Water Permit issued by the <br />Minnesota Pollution Control Agency. A copy of the most recent Annual <br />Complianace Report, dated April 10, 1995, is found attached. (See Appendix <br />#1 B, page 15). <br /> <br /> Mining operations comply with all regulatory agencies in order to maintain <br />water quality. In order to minimize the chance of spilling fuel or lubricants, the <br />machinery is serviced in the shop facility. (See Appendix #2 for Job Safety <br />Practice Sheet #5-105, page 16, relevant to this text). Existing fuel storage tanks <br />are above ground and the new tank planned for installation by ERL will have <br />secondary containment walls. All fuel pumps have locking devices. <br /> <br />11 <br /> <br /> <br />
