Observa [ions within <br /> [he mixed brush, sandstone-derived soils indicated very suitable loamy soil was salvaged <br /> down to the trot [ u red sandstone bed rock. The thickness of recovered soil ranged from 0.5 <br /> feet on ridgetops to about 3.0 feet in Swa le or drainage landscapes. <br />SCC will continue to closely monitor soil handling operations during [he 1997 field season. <br />only suitable sources of soil within the disturbance area will be salvaged to ensure the <br />reclaimed areas are restored [o the desired pos tmine land uses. SCC will obtain variances <br />pursuant to Rule 4.06.2(2) and Permit C-82-057 whenever suitable soil cannot be salvaged <br />exclusively from any map unit because of equipment limi [a lions or operator safety concerns. <br />Soil Redistribution Thickness <br />SCC is required by Permit C-82-057 and Section 4.06.4 (2)(b) of Colorado's Regulations for <br />Coal Mining [o document and record the soil redistribution thickness for each reclamation <br />block using a minimum sampling intensity of one hole per five acres. The soil replacement <br />thickness information is used [o adjust soil salvage depths, if necessary, and for bond <br />release purposes. Soil replacement thickness was measured November 12, 1996 for reclaimed <br />• areas which had soil replaced during 1996 (21.5 acres). <br />Data was collected from Eive sites during the 1996 field season. Sail thickness fox the <br />1996 reclamation blocks ranged from 1.0 to 1.8 feet. Samples were taken with a shovel, and <br />a tape measure was used [o determine topsoil replacement depth. The sample data - 18", <br />20•, 21', 14", 12" was taken by Aoy Karo. The mean soil replacement thickness for 1996 was <br />1.4 teat. 7 S ~p,LQ.lnen U <br />Spoil Sampling in [he Lennox Coal Outcrop Area <br />No final grading was conducted in any portion of the Lennox Coal outcrop area during the <br />1996 field season. Therefore, no spoil samples were collected. <br />Soil Pit ~ Soil Fertility - RevegeGa lion Monitoring <br />Shallow pos[mine soil pits are excavated periodically near representative revegetation <br />monitoring sites to evaluate plant rooting characteristics, determine soil fertility, <br />ensure spoil suitability, and compare soil/spoil data with site-specific revege to ti on data. <br />The pits are selected using an intensity of one pit per 25 acres of reclamation. Postmine <br />• soil pi [s are placed within reclamation blocks that have been soiled and seeded for a <br />minimum of three years. Similar minimum time frames are used Eor monitoring postmine <br />vegetation. The permanent vegetation has generally established sufficiently after three to <br />
