• SUMMARY OF COALDALE h1I1fING PLAN BY AREA <br />(Refer to Mining Plan Maps for Locations) <br />Senatore Hill <br />The central portion of the ore horizon as shown on the Affected Land <br />Overlay is named Senatore Hill, comprising 10.7 acres of Affected land. <br />Development work initiated in 1975 is now concentrating on level develop- <br />went at the 6900 elevation. By 1982, hangingwall material will be pushed <br />to the Northeast, facilitating development of ore extraction levels below <br />the 6900 level, and will continue downward and slightly East for the life <br />of mine. Reclamation activities will start as soon as hangingwall develop- <br />went is completed, about 1983, although the interior pit, as per tfagazine <br />. Hill, will be delayed from reclamation efforts until mining is completed <br />in these areas. The Senatore Hill Area presently offers an excellent <br />example of the poor mining practices of the past. A 40' thick, deeply <br />dipping gypsum bed was mined out in this area, leaving behind an extremely <br />dangerous, 120' overhanging highwall over 350' long. In order to mine <br />the remaining gypsum in this area, the entire highwall must be removed <br />part of the "hanging wall" area on the North East side the gypsuu: deposit. <br />• <br />
