• To the extent that it is operationally feasible, coarse and fine refuse <br />will be mixed during construction of successive lifts. Each lift will be <br />compacted to a density of 90 percent of maximum dry density prior to <br />placement of the next successive lift. Periodic testing will be utilized <br />to verify consistency with compaction specifications. <br />During refuse pile construction, active working areas will be sloped and <br />oriented to provide effective drainage from the surface of each completed <br />lift. If necessary, temporary ditches may be established in working areas <br />to collect and route runoff from the refuse pile to the perimeter <br />collection ditches. <br />EFCI will continue to add successive lifts until the design refuse pile <br />height is achieved. The existing refuse stockpile varies in height from <br />approximately 70 feet at the east end of the stockpile to approximately <br />45 feet along the current stockpile crest. In order to maximize stockpile <br />• capacity within the stability design constraints, EFCI proposes to <br />establish a 3H:1V slope from the current crestline sloping upward to the <br />west to a height of approximately 75 feet. The top of the stockpile will <br />then level off maintaining a gradual slope to the east consistent with the <br />natural slope of the land. <br />Successive lifts on the outslope of the refuse pile will be offset to <br />establish an outslope gradient of 2H:1V or less. Generally, EFCI will <br />construct outslopes of the refuse pile at a gradient of approximately <br />3H:1V to facilitate future reclamation. The final design configuration <br />is illustrated by the Coal Refuse Pile Expansion Map, (Map TR07-1). <br />• <br />9R Revised - February, 1990 <br />
