<br />0.8 feet of direct hauled fine sandy loam topsoil. Two-lift soil replacement was used <br />because the fine clay loam/clay soil has good subsoil water holding properties; the fine <br />sandy loam soil provided better seedbed filth and fertility characteristics, and placing <br />direct hauled soil et the surface allows for transfer of native seed, rhizomes, and <br />microbes. The minimum mean soil replacement Chickness for the first permit term is 1.3 <br />feet. <br />Topsoil Thickness Subsoil Thickness <br /> <br />• <br />Site No.(7) (feet) (feet) <br />4 0.7 7.3 <br />5 1.9 0.0 <br />6 0.7 1.1 <br />7 1.1 7.7 <br />()) See Exhibit 93.2 for site locations <br />Spoil Samolinc in the Lennox Coal Outcrop Area. No final grading vas completed in the <br />Lennox Coal outcrop area during the 7993 field season. Therefore, no spoil samples were <br />collected to determine acidity levels and clay percentages pursuant to Permit C-82-057, <br />Teb 21, Page 4. <br />According to Exhibit 79-1, Reclamation Schedule (dated 70/04!93) and Exhibit 6-6, <br />Overburden Coal Hole Location Map (dated 04/19/9)) from Permit C-82-057, the first Lennox <br />Coal outcrop area vill be graded and reclaimed in 1994, Spoil samples will be collected <br />from this area once final grading has been initiated. <br />Soil Pit-Soil Fertilitv-Reveaetation Monitoring. Shallow postmine soil pits are <br />excavated periodically near representative revegetation monitoring sites to evaluate <br />plant rooting characteristics, determine soil fertility, ensure spoil suitability, and <br />compare so(l/spoil data vith site-specific reveg elation data. The pits are selected <br />using a rate of one pit per 25 acres of reclamation. postmine soil pits are placed within <br />reclamai ion 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 (Schafer et al., 7979). <br />No soil or spoil sempl es were collected from shallow postmine soil pits during the 1993 <br />field season. According to the Reclamation Schedule, Exhibit 79-1, from Permit C-82-057, <br />3 <br />
