' MINING PLAN <br />The DeBetz Gravel Pit was initially excavated iri 1960 <br />by the previous property owners. Since acquiring the property <br />in 1973, Adams County has mined the land for purposes of gravel <br />extraction. This gravel git will continue to be operated by the <br />' County as a wet pit, primarily focusing its operations during the <br />late winter and early spring for a five to six month interval. <br />Average extraction amounts in the past have been approximately <br />' 100,000 tons annually. This tonnage is expected to range from <br />100,000 to 170,000 tons annually for the life of the permit. Act- <br />' ual mining and crushing of aggregate has been done by a contractor. <br />Screening and loading has been performed by Adams County p~:rsonnel. <br />' Equipment at the mining site during the operational months include <br />a dragline, dozers, front-end loaders, and an assortment o:F hauling <br />trucks. Since sand and gravel is stockpiled during operational <br />' months and utilized throughout the year for highway maintenance and <br />construction, a conveyor and a stabilization plant may be ].orated <br />' on the site on a year-round basis. <br />Phasing <br />1 The complete mining operation will be conducted in two <br />phases which will create a 42 acre lake when completed (see pageB-4). <br /> Phase I - Phase I will last for approximately 15 years <br /> and include the pit site within an existing fenced area, ap- <br /> proximately 44 acres. A mechanical dragline will extract the <br /> material after the overburden is removed and stockpiled. The <br /> <br /> aggregate will be separated according to particle size by a <br />B-2 <br />
