• percent for the mixed zone and underlying spoil layers, with an average of 40.3 percent. <br />Sodium adsorption ratio (SAR) is all good and ranges from 0.11 to 0.35 (nonsodic) for all <br />soil samples, and from 0.12 to 0.95 (nonsodic) for the mixed zone and underlying spoil <br />layers. Nitrate nitrogen values are also good for all soil samples and range from 0.57 to <br />7.87 ppm with an average of 2.97 ppm. Nitrate values for the mixed zone and underlying <br />spoil layers range from 0.31 to 4.26 ppm with an average of 1.76 ppm. <br />Acid-Base Potential (ABP), selenium, and boron, were not analyzed for the soil layers, <br />but were analyzed for the underlying mixed topsoil and spoil zone, and the underlying <br />spoil layers. All selenium and boron values were good with Selenium <0.05 ppm <br />(average 0.027), and Boron <0.$4 ppm (average 0.51). All ABP values are positive and <br />range from 14.3 to 74.8, with an average ABP of 47.4. <br />Reapplied Topsoil/Overburden Spoil (Backhoe Pits) Profile Descriptions: <br />Five Backhoe pits were dug on the Seneca Coal reclaimed lands -three on the 2W Mine <br />(2W-TS-07-P1, 2W-TS-07-P2, and 2W-TS-07-P3) and two on the toast Mine (Y-TS-07- <br />P1 and Y-TS-07-P2). The pits were dug down through the reapplied topsoil and into the <br />underlying overburden spoil. The Backhoe pits were dug to about six feet in depth, and <br />care was taken to provide a straight, clean sidewall and endwall for observation, <br />description, sampling, and photographic purposes. A soil profile description was <br />completed in the field at each Backhoe pit and samples were taken by horizons (layers) or <br />• depth interval, whichever was most appropriate. Soil profile and landscape photographs <br />of each pit are attached. The following profile descriptions were completed at the time of <br />soil sampling. <br />toast Mine Reclaimed Land Soil Pit Y-TS-07-PI (toast Pit 1) <br />Sample site Y-TS-07-P1 is located on reclaimed land at the toast Mine. Site <br />characteristics include: reclaimed 10% slope on a sideslope position; west-southwest <br />aspect; mixed reclamation grasses and forbs, excellent cover and productivity; reapplied <br />topsoil; well drained; moderate permeability; no erosion at site; sampled October 11, <br />2007; soil samples for lab include 0-8" (reapplied topsoil), 8-17" (reapplied topsoil), 17- <br />30" (mix of reapplied topsoil and weathered overburden spoil, primarily in lower part), <br />and 30-50" and 50 to 72" (overburden spoil). <br />A horizon - 0 to 8 inches; brown (lOYR 4/3) silt loam with 5% small sandstone and shale <br />fragments, dark brown (lOYR 3/3) moist; moderate medium granular structure; slightly <br />hard dry consistence, very friable moist consistence, slightly sticky and slightly plastic <br />wet consistence; common fine and very fine, and few to common medium and coarse <br />roots; slightly effervescent, slightly alkaline (pH 7.4, from lab data); gradual wavy <br />boundary. <br />AB horizon - 8 to 17 inches; brown (lOYR 4/3) silt loam with 5% small sandstone and <br />. shale fragments, dark brown (lOYR 3/3) moist; moderate medium subangular blocky <br />structure; slightly hard dry consistence, friable moist consistence, slightly sticky and <br />4 <br />
