<br />James B. McArdle <br />Sr. Reclamation Specialist <br />Mined Land Reclamation Division <br />August 13, 1985 <br />Page Two <br />The outer embankment of the pit will be a cavated to <br />a 3:1 slope from the existing grade to to feet <br />below the waterline, and at a 2:1 slope f om that <br />point down. The slope above waterline wi 1 be <br />notched back to allow for recoiling. (P1 se see <br />revised reclamation plan sheet). <br />Topsoil will be stripped ahead of the adva cing pit, <br />to a depth of six inches. Topsoil strippi g will <br />proceed far enough to uncover a 180 day s ply of <br />sand and gravel. This corresponds to 0.6 cres at <br />the estimated rate of mining. <br />The outer embankment will be recoiled and evegetated <br />concurrent with mining. Buffer zones with'n the 100 <br />year flood zone will be recoiled to a dept of 6 to <br />12 inches. Buffer zones above the flood z ne will <br />serve as topsoil stockpile areas. Resoili g in these <br />areas will be to a depth of 18 to 24 inche . <br />The western portion of the property, Minin Area I, <br />will be mined first, as shown on the minin plan. <br />The eastern portion, Mining Area II, will a mined <br />next using the same steps outlined above. <br />3. The mining plan has been revised to show t psoil <br />stockpiling in those buffer zones which ar above <br />the 100 year flood zone. These areas are abeled <br />"T.S. Stockpile Area". (Please see revise mining <br />plan sheet). ~ <br />4. The operator intends to stockpile topsoil <br />separately, to maintain the stockpile slops at no <br />greater than 3:1, and to seed the stockpil s as <br />necessary to prevent erosion. <br />5. A total of 34,500 cubic yards of topsoil w'll be <br />stripped during the life of the mine. The ultimate <br />pond will contain approximately 36 acres o water <br />surface, leaving a maximum of 19 acres in ,eed of <br />recoiling. This wil`~a~w an average recoiling <br />depth of greater than 12 inches. <br />
