2.05.3(6) (c) <br />• Overburden from <br />will be removed <br />amound of waste <br />#2 Mine. Refer <br />underground dev <br />the proposed underground development waste disposal site <br />in stages. These stages will be determined by the <br />developed in the Red Canyon #1 t?ine and proposed <br />to Section 2.05.3(9) for details on the proposed <br />=lopment waste disposal site. <br />In general, overburden will be removed from a specified area. The <br />specified area will be a site chosen to be utilized for fill with <br />underground development waste. The overburden will be removed at an <br />average depth of two or ten feet with a dozer and stockpiled near the <br />area in question. Refer to the Proposed Surface Disturbance Map, <br />2.05.3(2)(b)-1, for the location of the overburden stockpile in <br />relation to the fill areas. When the area has been filled with <br />underground development waste and graded, the overburden will be <br />replaced at a depth of 3.5 feet. As with the topsoil stockpile, <br />(refer to Section 2.05.3(5)), the overburden stockpiles will be <br />located so as not to be disturbed by mining operations. <br />• Referring to Soils Resource Information, Section 2.04.9, it is <br />noted that the topsoil and overburden are medium in nitrogen and <br />low in phosphorus fertility. Before any revegetation is done, <br />20 pounds of nitrogen and 60 pounds of phosphorus per acre will be <br />mixed with the overburden. <br />Overburden will be replaced on the fill areas by means of a loader or <br />earthmover, spread with a dozer, and compacted with a sheepsfoot <br />roller to a depth of 3.5 feet. <br />• <br />II¢ <br />
