gallons of water per acre. Drill seeding was done on slopes accessible <br />with drill seeding equipment. On these reduced slopes, straw mulching <br />and tackifying was done at the same rates as the steep slopes. The <br />permanent seed mix was used on the refuse piles and borrow areas <br />where no further access would be needed. In borrow areas and topsoil <br />stockpiles where further access will be needed, the temporary seed mix <br />was used. Approximately 5 pounds per acre of oats was added to these <br />mixes for rapid ground cover. Hydroseeded areas were seeded at double <br />the listed rate for drill seeding. <br />Contemporaneous reclamation on the CRDA's will continue. To minimize <br />the potential of contamination on a covered bench, one complete bench <br />and outslope below that bench will be maintained between the active fill <br />area and the covered areas. Within a year of completion of the second <br />bench above the covered area, work will be completed on covering the <br />lower bench and outslope. The time schedule for covering a bench may <br />be delayed another year if the bench is actively dewatering through seeps. <br />Upon completion of a pile, the reclamation in accordance with the time <br />• table in Figure 14-1 will be started within a year. <br />Final reclamation of disturbance associated with the South Lease <br />Exploration Plan was done in 1985-1987. Reclamation of the North <br />Decline area was started during the summer of 1991 and completed in the <br />spring of 1993. Refer to Exhibit CMC Mining Inc, January 20, 1976 for <br />topography and Exhibits 12C and 28 for North Decline PostMining <br />topography. An area of 18.3 acres which included the North Decline, the <br />water treatment ponds and the storage area was regraded in the spring of <br />1982 and seeded that fall. The Al substation, a powerline between A and <br />Al substations and the water treatment building at the North Decline were <br />removed during the spring of 1993 and minor regrading and seeding was <br />performed. <br />Upon demonstration that disturbed area sediment controls are no <br />longer necessary at the North Decline, additional reclamation work will <br />include backfilling and grading the two small area exemption sediment <br />traps, reclamation of Pond 7, and installing berm breaks along the <br />permanent channel at appropriate locations to allow reclaimed area <br />drainage to enter the channel. <br />14-3 (Rev. 11 /01) <br />
