Soil Pit-Soil Fertilitv -SOOiI guality. Soil fertility end spoil quality samples are <br />• <br /> collected peri odiceLly tram shallow postmine soil pits which are placed near representative <br /> revegetation monitoring sites. The postmine soil pits are also used to evaluate plant <br /> rooting characteristics end to compare soil/spoil profile data with site specific <br />revegetation data. <br />Postmine soil pits ere placed within reclamation blocks [hat have been soiled and seeded <br />for a minimum of three years. Similar minimum time frames are used for monitoring postmine <br />vegetation. The permanent vegetation has generally established sufficiently after three to <br />four years to evaluate int erections between rooting characteristics and soil/spoil quality <br />(Schafer et. el., 1979). <br />No soil or spoil samples were Collected near revegetation sampling points during the 1993 <br />field season. Historical soil end spoil quality date for the 1983 through 1988 reclamation <br />blocks are presented end discussed in previous Topsoil end Spoil Monitoring reports or <br />Annual Reclamation reports that have been submitted to CDMG (PCC, 1987, 1989 and 1992). <br />Representative revegetation sites from reclamation years 1989, 1990, and 1991 are scheduled <br />to be sampled during the 1994 field season. <br />Sooil Samolinc in the Lennox Hi ah wall Reduction Aree. Peabody is required to sample final <br />graded spoil from the Lennon highwall reduction area (in the immediate vicinity of Drill <br />Mole Site 2614E) on a 300 foot grid and test for sodium. Exposed sodic strata will either <br />be buried in the final pit or covered with two to three fee[ of suitable spoil prior to <br />soil replacement. No final grading was completed in the Lennox highwall reduction area <br />during the 1993 field season. Therefore, no spoil samples were collected to determine <br />sodium levels. <br />According to Exhibit 13-2, Reclamation Plan (dated 01/26/93), the remaining 2,000 feet of <br />Lennox highwall in the vicinity of Drill Hole Site 2614E, will be reduced end reclaimed in <br />1998. Spoil samples will be collected from this area once final grading has been <br />completed. <br />Wolf Creek Spoil. Peabody is required to sample end analyze final graded spoil from the <br />Wolf Creek mining area prior to soil repl et ement. Spoil is sampled on a 300 foot <br />• horizontal grid end tested for pH, acid base potential (ABP), end soil salinity (EC). A <br />selectively handling suitable spoil topdressing (subsoil) is made prior to soil replacement <br />2 <br />
