SCC will continue to closely monitor soil handling ope rat Sons during [he 2000 field season. <br />Only suitable sources of soil within the disturbance area will be salvaged to ensure the <br />reclaimed areas are restored to the desired postmine land uses. SCC will obtain variances <br />pursuant to Rule 4.06.2 (2~ and Permit C-94-082 whenever suitable soil cannot be salvaged <br />exclusively from any map unit because of equipment limitations or operator safety concerns. <br /> <br />i• <br />1999 So11 Replacement Thickness <br />SCC is required by Permit C-94-082 and Section 4.06.4 (2((b( of Colorado's Regulations for <br />Coal Mining to document and record the soil replacement thickness for each reclamation <br />block using a minimum sampling intensity of one hole per five acres. The soil replacement <br />thickness Sn£ormat ion is used to adjust soil salvage depths, if necessary, and for bond <br />release purposes. Soil replacement thickness was not measured during the 1999 field season <br />since no topsoil was replaced on graded spoil in 1999. <br />SCC Ss submitting the soil balance with the Annual Reclamation Report as required by Permit <br />C-94-082, Tab 21, Pages 5, 25, and 26, and as recommended by Section <br />32.04.13(2( of Colorado's Regulations for Coal Mining. The soil balance is completed to <br />ensure soil is salvaged, stockpiled, and replaced as recommended and approved in [he <br />permit, and, if necessary, to readjust the soil salvage and redistribution thickness. The <br />soil information is also used to update the soil volume information previously submitted <br />with the 1998 Annual Reclamation Repo ct ~$CC, 1999) and confirm the mean soil replacement <br />thickness for the first five-year permit term. <br />Soil Salvage and Storage <br />The disturbance area from which soil was salvaged and the soil stockpile sites as of <br />December 31, 1999 are shown on drawing Y99TSREM. During 1999, all soil was imported to <br />stockpiles H, K and L. <br />The actual volume of soil salvaged and stockpiled from 1995 through December 31, 1999 was <br />determined by field survey of existing soil storage stockpiles. The base and existing <br />elevations for each stockpile were completed by the Seneca engineering staff. The stockpile <br />volumes as of December 31, 1999 are listed in Table 99.1. As of December 31, 1999, 560.2 <br />acre-feet of soil were stockpiled in the mining area. <br />2 <br />
