• SCC will continue to closely mo nito[ soil handling operations during the 1999 field season. Only suitable sources of soil within the disturbance area will be salvaged to ensure the reclaimed areas are restored to the desired postmine land uses. SCC will obtain variances pursuant to Rule 4.06.22) and Permit C-94-082 whenever suitable soil cannot be salvaged exclusLvely from any map unit because of equipment llmi Cations or operator safety concerns. 1998 Soil Replacement Thickness SCC Is required by Permit C-94-082 and Se ct lon 4.06.4 ~2~~b~ of Colorado's Regulations for Coal Mining [e document and record the soil replacement thickness for each reclamation block using a minimum sampling intensity of one hole per five acres. The soil replacement thickness information is used Co adjust soil salvage depths, if necessary, and for bond release purposes. Soil replacement thickness was not measured during the 1998 field season since no topsoil was replaced on graded spoil ir. 1998. Soil Balance SCC Ss submltting the soil balance with the Annual Reclamation Repo r[ as required by Pe rmlt • C-94-OB 2, 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, stockplled, and replaced as recommended and approved in the permlt, and, If necessary, [o readjust the soil salvage and red is[nbution thickness. The soil lnformatlon Ss also used Co update the soil volume information previously submitted ui[h the 1997 Annual Reclamation Report ~$CC, 1558 and confirm [he mean soil replacement thickness for the first five-year permit term. Soil Salvage and Storage The disturbance area from which soil was salvaged and the soil stockpile sites as of December 31, 1998 are shown on drawl ng Y9BTSREM. During 1998, all soil was imported to stockplles D, F, G, R, I and K. The actual volume of soil salvaged and stockpiled from 7995 through December 31, 1998 was determined by field survey of exls[ing soil storage s[ockpl]es. The base and er.i sting eleva [tuns Eor each stock. pile were compl e[ed by [he Seneca II-w engineerin g staff. The stockpile volumes as of December 31, 1998 are listed in Table 90.1. As of December 31, • 1998, 449. 8 acre-fee[ of soil were stockpiled to [he mining area. 2
