Permit# M-2016-040 <br /> AGPRO Project#: 1342-01 July 12, 2017 <br /> GEOTECHNICAL STABILITY EXHIBIT <br /> This information is presented to address the plan to mine within 200 feet of the fence located <br /> along the northern property line of the Betty L. Mills Trust property. The mine depth adjacent to <br /> where no structure agreement has been obtained is 45 feet. This is a dry mining operation and <br /> mined dry. The setback from the permit/affected lands lines to the dig line will be 20 feet and <br /> the fence at its closest point is 11.8 feet from the property line. <br /> The following information is presented using these distances to determine the safety factors that <br /> show there would be no potential impact to structures within 30 feet of the mine face during <br /> mining. During mining, and when mining is complete and the slopes reclaimed to the final 3:1 <br /> slope, the 20 foot setback will be safe. <br /> When mining approaches the perimeter of the mine area a 20 foot setback will be staked from <br /> the perimeter line to establish the mining limit. As the mining gets to within 30 feet of the <br /> perimeter the operator will ensure that the 3:1 slopes are maintained to prevent the slope from <br /> failing until mining and final grading is complete. As soon as mining is complete within the <br /> permitted area, the side slopes will be brought into the final 3:1 slope and a soil amendment will <br /> be tilled into the slopes and re-vegetation with the approved grass mixture will occur. <br /> The mine operator will repair or compensate damages that occur to the fence due to mining <br /> traffic along the mine perimeter and along the haul road. <br /> Sirs <br /> 'a y1 <br /> Chad TeVelde, PE <br /> Sr. Professional Engineer <br /> ENGINEERING, PLANNING, CONSULTING & REAL ESTATE <br /> 3050 67`h Avenue,Greeley, CO 80634 <br /> 970.535.9318/office■ 970.535.9854/fax■ www.agpros.com <br />
