• The site where the borehole will be drilled and the storage tank <br />placed will be stripped of topsoil prior to disturbance. The site is <br />located in a Turret soil (mapping unit 606) and approximately 18 inches <br />of topsoil is available far salvage from this series. The reader is <br />referred to Appendix III-9 for a discussion of the suitability of this <br />soil as a plant growth media. The topsoil, approximately 750 yd3, is <br />salvaged and stockpiled adjacent to the borehole and tank. The borehole <br />is drilled into the 2nd East Mains at an approximate depth of 300 feet. <br />The borehole will be cased its entire length, thus eliminating any <br />potential impacts on the hydrologic regime of the area. No significant <br />amounts of water were encountered during the drilling of the borehole. <br />The underground distribution system will carry the fresh water to <br />• various sections of the mine. The major usage of the water will occur <br />in the Empire Tract. <br />The reclamation plan for the system is found later in this section. <br />Reclamation costs are presented in Appendix IV-13. <br />Magazine <br />Empire Energy stores explosive devices in the magazines identified <br />on Map IV-2. Both of these structures are marked and locked to prevent <br />j tampering with materials contained within them. They both are <br />relatively small structures and can be easily moved by use of a chain <br />and front end loader. The road leading into the site is shown on flap <br />IV-15. <br />• Due to the small disturbance associated with them, approximately <br />lOG ftz, a variance is requested from sediment control requirements. Plo <br />additional contributions of sediment should be realized from the sites. <br />(REV. 12/13/83) IV-44h <br />
