2000 ANNUAL RECLAMATION REPORT <br /> NH 1 <br /> No activity occurred on the NH area in 2000. Although no fertilizer was applied to any area, <br /> Exhibit 99.1 shows the location, as well as the 2°1 cut pasture yield total of about 9.0 st (2,813 <br /> lb/acre), from the 6.4 acre area. For reference, Exhibit 2000-2 shows the pre-1993 disturbance at <br /> NH1. <br /> NH2 <br /> Existing Disturbance <br /> During 2000, 8.20 acres of new disturbance was associated with the mining program at New Horizon <br /> 2 Mine. The 2000 Disturbance and Seeding Maps,Exhibit 2000-3 and 2000-4 respectively, show <br /> the areas either disturbed, reseeded, or both, during 2000. <br /> Backfilling and Grading <br /> During 2000, 36.05 acres were graded at New Horizon 2. Backfill grading was accomplished by <br /> backfilling the empty pit with a truck-shovel fleet and then final grading with D-9 dozers and 14G <br /> grader. <br /> Soil and Spoil Scarification <br /> The following soil and spoil scarification techniques were used while grading the reclamation area. <br /> Prior to growth media soil replacement, the final graded spoil was scarified to a depth of 6 to 18 <br /> inches using ripper shanks attached behind a motor grader. This scarifying operation effectively <br /> reduced compaction, reduced runoff, and improved infiltration, while improving rooting depths. <br /> Soil and Spoil Monitoring Data <br /> New Horizon Mine is required by Permit C-81-008 to monitor replaced soil and final graded spoil <br /> and submit the information to the Division. Monitoring programs include verifying soil replacement <br /> thickness and determining final graded spoil quality. Exhibit 2000-6 (topsoil thickness and sample <br /> snap), and 2000-7 (backfill spoil sample map), shows the locations of the sample sites along with <br /> the thickness of the topsoil replacement. <br /> Spoil Quality <br /> The spoil sampling and analysis program approved for New Horizon Mine is described in <br /> Section 2.05.4(2)(d)-4 Regraded Spoil Monitoring Program of Permit C-81-008. Backfill spoil <br /> samples for 2000 were collected from four sites in the New Horizon 2 area. Samples were <br /> collected from the sidewalls of four foot deep pit that was excavated with a rubber tired backhoe <br /> • (d:\data\wpdata\rec-repo\2000recrepo.doc) <br />
