,iii i_iiiiiiiiiiii iii _ 999 Doc Date:12/11/2001 1995 ANNUAL RECLAMATION REPORT • Existing_Disturbance During 1995, 42.90 acres of new disturbance was associated with the mining program at New Horizon 2 Mine. The 1995 Seeding and Disturbance Maps, Exhibit 95.1 and 95.2, show existing disturbance areas as of December 31, 1995. A small area was added to the 1995 disturbance that was done in 1993. This area is located by the shop and encompasses 1.88 acres. Therefore. a total of 44.78 acres will be claimed in 1995. Backfilling and Grading During 1995, 43.33 acres were graded at New Horizon 2. Backfill grading was accomplished by backfilling [he empty pit with a [tuck-shovel flee[ and then final grading with D-9 dozers and 14G grader. Soil and Spoil Scarification The following soil and spoil scarification techniques were used while grading the reclamation area. Prior to growth media soil replacement, the final graded spoil was scarified to a depth of 12 to 18 inches using ripper shanks attached behind a motor grader. This scarifying operation effectively reduce compaction, reduce runoff, and improve infiltration, while improving rooting depths. Soil and Spoil Monitoring__pata Ne~v Horizon Mine is required by Permit C-81-008 to monitor replaced soil and final graded spoil and submit the information to the Division. Monitoring programs include verifying soil • replacement thickness and determining final graded spoil quality. Exhibit 95.4, topsoil thickness and sample location map, and Exhibit 95.5, Sub-soil Sample Location Map, shows the location of the sample sites along with [he thickness of soil replacement. Spoi! Qualify The spoil sampling and analysis program approved for New Horizon Ivtine is described in Tab 21 of Permit C-81-008. Spoil samples were collected from IS sites in the New Horizon 2 area. Samples were collected from the sidewalls of four foot deep pit, excavated with a rubber tired backhoe. All spoil samples were shipped to Colorado State University Soil Testing Lab in Fort Collins, Colorado for analysis. The location of each spoil pit is shown on Exhibit 95.5, Backfill Spoil Sampling Location Map. Laboratory results for the 30 spoil samples are presented in Attachment 95.A. The analytical results indicate al] spoil is suitable. No additional grading, special handling, or amendment application was needed prior to soil replacement. Topsoil Redistribution 11,950 cubic yards of Lift 1, D70B, topsoil was moved from an existing stockpile to reclaim the Prime Farmland as per the Permit Regulations. The remaining volume of topsoil that was used for redistribution was live handled from ahead of the active mining area to the awaiting backfill area. In two separate topsoil campaigns, ;t total of 52,400 cubic yards in Phase V and •
