EXHIBIT "D" -MINING PLAN (Technical Revision 6-20- 85, Pale 2) <br />The following is the solid waste disposal plan that the McKenzie Pit has proposed <br />per the operator. <br />As previously stated, the asphalt and concrete waste dumped in designated piles <br />on the northern boundary of phase two and covers approximately 1/4 acre will be <br />graded to a flat surface and compacted in 3 ft. layers. This is needed as fill to <br />raise and level the area for a crusher and stockpile to be implemented for use as <br />the mining proceeds west. After mining ceases, this area will be covered with <br />6 inches of topsoil to insure a growth media for revegetation. Also, as stated <br />before, there will be a three ft. berm constructed along the top of the mesa of earth <br />and concrete to insure that no waste concrete or asphalt will go downslope. There <br />will be no more asphalt and concrete dumping on the northern boundary of the permit <br />boundary, <br />Disposal of the waste asphalt and concrete shall be started along the highwall <br />between Area "A", Phase One and the topsoil storage area in the southwestern corner <br />of Area "A", phase one and shall proceed north along the highwall as the need arises. <br />as outlined in Map in Exhibit "C" in Blue. The waste material shall be hurried under <br />the backfill materia), compacted and then sloped to a 2 1/2:1 slope with topsoil spread <br />over the top at 6 inches in depth and re vegetated per the Reclamation Plan seeding <br />specifications. <br />SURFACE DRAINAGE PLAN -The following is a functional drainage system for <br />the Mckenzie Pit: Runoff from the Brookside Corporate boundary area upslope from <br />the sand and gravel pit is approximately 6 acres and will be diverted around the <br />surface mine by a diversion constructed dope (to the south) from the operations. <br />This ditch will catch and direct runoff to the natural drainage west of the operation. <br />(See the enclosed map, Exhibit "C"j. <br />For a small basin, the diversion should be appropriately sized for the short term, <br />
