• YOAST MINE 2004 ANNUAL RECLAMATION REPORT 2004 DISTURBANCE AREA The Yoast Mine 2004 Reclamation Map shows the limits of disturbance as of December 31, 2004. The disturbance line as shown on this drawing depicts all disturbance associated with the minittg operation including haul road and pond construction, topso$ removal and storage, open pits, spoil piles, etc. There were 20.4 additional acres disturbed during 2004. BACgPILLING AND GRADING During 2004, SCC graded a portion of the active pit spoil. This area totals 91.7 acres and is shown on the Yoast Mine 2004 Reclamation Map. SOIL AND SPOIL MONITORING SCC is required by Permit C-94082 to monitor the salvage, storage, and redistribution of soil and spoil handling operations at Yoast Mine. Specific programs include documenting soil recovery, verifying soil redistribution thickness, detennitting final graded spoil quality, determining soil fertility, evaluating plant rooting chazaderistics, recording the source of replaced soil, and completing an annual soil balance. The following sections present the soil and spoil monitoring data for the 2004 • calendar yeaz. The Soils Report is attached • Soil Recovery Documentation Topsoil was removed from 20.4 acres in 2004. Soil recovery was docurnented by daily observation by the grading foreman and pit supervisor. This quality control information is used to verify soil salvage estimates predicted from the baseline soil survey, confirm soil map unit types, justify salvage thickness, and evaluate soil suitability. So$ salvage occurred in advance of the active pit during the 2004 field season as shown on the Yoast Mine 2004 Reclamation Map. All topsoil salvaged during this period was live handled and placed on previously graded spoil azeas. • 2004 Soil Replacement Thickness SCC is required by Pemrit C-94-082 and Section 4.06.4(2)(b) of Colorado's Regulations for Coal Mining to document and record the soil replacement thickness for each reclamation block using a mittitnum sampling intensity of one hole per five acres. The soil replacement thickness information is used to adjust soil salvage depths, if necessary, and for bond release purposes. Topso$ replacement depths were sampled d",r ~ 2004 field season. Samples were taken on a random line across the topsoil replacement azea. The average topsoil replacement depth for the 2004 azea is 1.3 ft. • Soil Balance. SCC is submitting the soil balance with the Annual Reclamation Report as required by Permit C-94- 082, Tab 21, Pages 5, 25, and 26, and as recommended by Section 32.04.13(2) of Colorado's • Regulations for Coal Mining. The soil balance is completed to ensure soil is salvaged, stockpiled, and replaced as recommended and approved in the permit, and, if necessary, to readjust the soil salvage and redistribution thickness.
