1998 ANNUAL RECLAMATION REPORT Existing Disturbance During 1998, 22.82 acres of new disturbance was associated with the mining program at New Horizon 2 Mine. The 1998 Seeding and Disturbance Maps, Exhibit 98.1 acid 98.2, show existing disttvbance areas as of December 31. 1998. Backfillin@ and Grading During 1998, 19.56 acres were graded at New Horizon 2. Backfill grading was accomplished by backtilling the empty pit with atruck-shovel fleet 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 Data New Horizon Miue is required by Penni[ 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 98.5, topsoil thickness attd sample location map, and 98.6, sub-soil sample location map, shows the location of the sample sites along with the thickness of soil replacement. Technical Revision # 39 was submitted to DMG requesting the subsoil sampling program be eliminated from the second half of 1998 onward. As of this submittal, if is WFC's understanding that this TR will be approved. Therefore. Exhibit 98.6 will show the locations of sub-soil sample locations that were tested in [he firsthalf of the year. Spoil Ouality The spoil sampling and analysis program approved for New Horizon Mine is described in Tab 21 of Permit C-81-008. Spoil samples were collected from 77 sites in the New Horizon 2 area. Samples were collected from the sidewalk 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 98.6, Backfill Sampling Location Map. Laboratory results for the 77 spoil samples are presented in Attaclunent 98.A. The analytical results indicate all spoil is suitable. No additional grading, special handling, or amendment application was needed prior to soil replacement. As mentioned about, this testing program will be discontinued once TR#39 is approved. • Id: \data\wpda to\rec-repo\98 recrepo.doc)
