• YOAST MINE <br />2004 ANNUAL RECLAMATION REPORT <br />2004 DISTURBANCE AREA <br />The Yoast Mine 2004 Reclamation Map (Topsoil Removed) shows the limits of disturbance as of <br />December 31, 2004. The disturbance line as shown on this drawing depicts all disturbance associated <br />with the mining operation including haul road and pond construction, topsoil removal and storage, <br />open pits, spoil pIles, etc. There were 23.1 additional acres disturbed during 2004. <br />BACgFILLING AND GRADING <br />During 2004, SCC backfilled and graded a portion of the active pit spoil. This azea totaled 77.9 acres <br />and is shown on the Yoast Mine 2004 Redamation Map (Graded Area). <br />SOIL AND SPOIL MONITORING <br />SCC is required by Permit C-94082 to monitor the salvage, storage, and redistribution of soil and <br />spoil handling operations at Yoast Mine. Spedfic prograzns include documenting soil recovery, <br />verifying soil redistribution thickness, determining final graded spoil quality, deteutuniug soil fertility, <br />evaluating plant rooting characteristics, recording the source of replaced soil, and completing an <br />annual soil balance. The following sections present the soil and spoil monitoring data for the 2004 <br />calendaz yeaz. The Soils Report is attached. <br />• • Soil Recovery Documentation <br />Topsoil was removed from 23.1 acres in 2004. Soil recovery was documented by daily observation by <br />the grading foreman and pit supervisor. This quality control information is used to verify soil salvage <br />estimates predicted from the baseline soil survey, confirtn soil map unit types, justify salvage <br />thickness, and evaluate soil suitability. Soil sah=age occurred in advance of the active pit during the <br />2004 field season as shown on the Yoast Mine 2004 Reclamation Map (Topsoil Removal). All topsoil <br />salvaged during this period was live handled and placed on previously graded spoil azeas. <br />• 2004 Soil Replacement Thiclmess <br />SCC is required by Perrnit C-94082 and Section 4.06.4(2)(6) of Colorado's Regulations for Coal <br />Mining to document and record the soil replacement thickness for each reclamation block using a <br />minimum sampling intensity of one hole per five acres. The so$ replacement thickness information is <br />used to adjust soil salvage depths, if necessary, and fox bond release purposes. Topsoil replacement <br />depths were sampled during 2004 field season. Samples were taken on a random line across the <br />topsoil replacement azea. The average topsoil replacement depth for the 2004 azea was 1.3 fr. <br />• Soil Balance. <br />SCC is submitting the soil balance with the Annual Reclamation Report as required by Permit C-94- <br />082, Tab 21, Pages 5, 25, and 26, and as recommended by Section 32.04.13(2) of Colorado's <br />Regulations for Coal Mining. The soil balance is completed to ensure soil is salvaged, stockpIled, and <br />. replaced as recommended and approved in the permit, and, if necessary, to readjust the so$ salvage <br />and redistribution thickness. <br />
