Coal outcrop area will be graded and reclaimed in 1994. Spoil samples will be collected <br /> from this area once final grading has been initiated. <br />Soil Pi t-Soil Fertilitv-Revegetation Monitoring. Shallow postmine soil pits are <br />excavated periodically near representative revegetation monitoring sites to evaluate <br />plant rooting characteristics, lietermine soil fertility, ensure spoil suitability, and <br />compare soil/spoil data with site-specific revegetation data. The pits are selected <br />using a rate of one pit per 25 acres of reclamation. Postmine soil pits are placed within <br />reclamation blocks that have been soiled and seeded for a minimum of three years. <br />Similar minimum time frames are used for monitoring postmine vegetation. The permanent <br />vegetation has generally established sufficiently after three to four years to evaluate <br />interactions between rooting depths and soil/spoil quality. <br />No soil or spoil samples were collected from shallou postmine soil pits during the 1991 <br />field season. According to the Reclamation Schedule, Exhibit 19-1, from Permit C-82-057, <br />[he first 25 acres of permanent rec Lamation will no[ be completed until 1994. Therefore, <br />sampling from shallou postmine soil pits will not be initiated until the 1997 or 1998 <br />field seasons. <br /> <br />Soil Replacement Technique. The three soil replacement areas for the 1991 field season <br />ere shown on Exhibit 91.2, 1991 Soil Resource Map. Soil replaced on the 7.8 acres of cut <br />slopes along Haul Road A was hauled from Stockpile J. Soil replaced on the 2.9 acres of <br />final graded slopes in the boxcut area was direct hauled. <br />Soil Balance. Peabody is submitting the soil ba Lance with [he Annual Reclamation Report <br />as required by Permit C-82-057, Tab 21, Pages 5, 32 and 33, and as recommended by Section <br />2.04.13(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 the <br />permit, and, if necessary, to readjust soil salvage and redistribution thickness. The <br />soil information is also used to update the soil volume information Peabody submitted <br />with permit revision No. 1 and confirm the mean soil replacement thickness for the first <br />five-year permit term. <br />Soil Salvage and Storage. The disturbance area from which soil was salvaged and the soil <br />stockpile sites as of December 31, 1991 are shown on the 1991 Soil Resource Map, Exhibit <br />. 91.2. The following technique was used to prepare the 1991 Soit Resource Map. The soil <br />3 <br />
