2.04.13(2) of Colorado's Regulations for Coal Mining. The soil balance is completed to <br />• ensure soil is selvaged, stockpiled, and replaced as recommended and approved in the <br />permit, and, if necessary, to readjust the soil salvage and redistribution thickness. <br />The soil information is also used to update the soil volume information previously <br />submitted with the 1993 Annual Reclamation Report (PCC, 1994) and confirm the mean soil <br />replacement thickness for the first five-year permit term. <br />Sail Salvage end Storage. the disturbance area from which soil was salvaged and the soil <br />stockpile sites as of December 31, 1994 are shown on Exhibit 94.2. During 1994, soil uas <br />imported to stockpile Sites GG, II, and JJ. Soil was exported from Stockpile Site H. <br />The actual volume of soil salvaged and stockpiled from 1989 through December 31, <br />1994 was determined by field survey of existing soil storage stockpiles. The base and <br />existing elevations for each stockpile were completed by the Seneca l!-w engineering <br />staff. The "Stork" volume calculating program was used to generate the soil stockpile <br />volumes presented in Table 94.1. As of December 1994, 69.7 acre-feet of soil were <br />stockpiled along the Tie-across haul road and 519.5 acre-feet of soil were stockpiled in <br />the mine area. <br />J <br />Soil Balance and Reolacement. The soil balance for the first permit term is calculated <br />for Seneca II-Y Mine by comparing [he disturbance area that requires soil replacement as <br />of December 31, 1994 with the soil reserve in stockpiles. The disturbance area for <br />Seneca II-N Mine, shown on Exhibit 94.1 with exception to the ti e-across haul road, <br />totalled 617.3 acres on December 31, 1994. Included in the disturbance area figure are <br />46.7 acres of soil stockpiles outside of the area to be affected by soil salvage, 19.5 <br />acres for the mine entrance road, 96.6 acres for the tie-across haul road, and 96.0 acres <br />where soil was replaced during 1990 through 1994. No soil uas salvaged or needs to be <br />replaced beneath the soil stockpile sites. Also, since the mine entrance road, Pond 005, <br />Pond 006, Haul Roed A, and Heul Road G are permanent postmine facilities, sail ui ll not <br />be replaced on 66.5 acres. The disturbance area requiring soil replacement as of <br />December 31, 1994 totals 407.5 acres at the mine site and 96.6 acres for the tie-across <br />haul road. <br /> Soil Reolacement Thickness. The soil replacement thickness for the first five-year <br /> permit term was projected to be 1. 3 feet for the mine area and 0.7 feet for the tie- <br />• <br /> across haul road. The soil balance as of December 31, 1994 was calculated as follows: <br />4 <br />
