Soil Pit-Soll Fertility-Revege to Lion Monitoring. <br />. Shallow pos [mine soil pits are excavated periodically near representative revege to ti on <br />monitoring sites to evaluate plant rooting characteristics, determine soil fertility, <br />ensure spoil suitability, and compare soil/spoil data with Bite-specific revege to [ion dose. <br />The pits are selected using an intensity of one pit per 25 acres of reclamation. Poetmine <br />soil pits are placed within reclamation blocks that have been soiled and seeded Eor a <br />minimum of three years. Similar minimum time frames are used Eor monitoring postmine <br />vegeta [ion. The permanent vegetation has generally ee tablished sufficiently after three to <br />four years to evaluate interactions between rooting depths and soil/spoil quality (9chafer <br />et al., 1979). <br />No soil or spoil samples were collected from shallow poetmine soil pits during the 1995 <br />field season. The first 25 acres of permanent reclamation on final graded spoil was <br />completed during 1993. Therefore, sampling from shallow pos[mine soil pits will be <br />initiated during the 1996 or 1997 ESeld season. <br /> Soil Replacement Technique. <br /> The soil replacement area for [he 1995 field season is shown on Exhibit 95.2b. 5o i1 was <br /> replaced on 15.0 acres of final graded slopes in the "A' Dit area, this soil came from <br />• stock <br />ile N which haU started t <br />lide eeded <br />d t be moved The areas covered from <br /> p <br />o s an <br />n o . <br /> stockpile N are shown in Exhibit 99.2b ( 15.0 acres). All advance topsoil removal in the 'A" <br /> pit area was imported into stockpile GG. <br />SCC submits [he soil balance with the Annual Reclamation Report as required by Permit C-B2- <br />057, Tab 21, Pages 5, 32, and 33, and ae recommended by Section <br />32.OA.13(21 of Colorado's Regulations Eor Coal Mining. The soil balance is completed to <br />ensure soil is salvaged, stockpiled, and replaced as recommended and approved in the <br />permit, and, if necessary, [o 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 1990 Annual Reclamation Report (SCC, updated by revisions and responses December <br />1995.) and confirm the mean soil replacement thickness for the first five-year permit term. <br />Soil Salvage and Storage. <br />The disturbance area Erom which soil was salvaged and the soil stockpile sites as of <br />December 31, 1995 axe shown on Exhibit 95.2a. During 1995, soil was imported [o stockpile <br />Site GC. Soil was exported from Stockpile Site N, completely depleting its reserve. <br />3 <br />
