underlying mixed zone of reapplied topsoil and regraded spoil (most often the third layer <br />down in the profile), pH averages 7.1 for 2W, and 7.35 for toast. For the underlying <br />spoil in the lower part of the backhoe pits, pH averages 7.3 (neutral) for 2W, and 7.8 <br />(moderately alkaline) for toast. <br />For the 2W Mine, electrical conductivity (EC) is low for the soil layers with a range of <br />0.14 (nonsaline) to 2.12 (very slightly saline), with an average EC of 0.62 (nonsaline). <br />EC ranges from 0.76 (nonsaline) to 3.61 (very slightly saline) in the underlying mixed <br />zone, with an average of 2.05 (very slightly saline). For the underlying spoil in the lower <br />part of the backhoe pits, EC averages 3.14 (very slightly saline). For the toast Mine, EC <br />is low for the soil layers with a range of 0.38 to 0.82 (nonsaline), with an average of 0.61 <br />(nonsaline). For the underlying mixed zone, EC ranges from 0.57 to 0.92, with an <br />average of 0.75 (nonsaline). For the underlying spoil in the lower part of the backhoe <br />pits, EC averages 0.64. <br />For all backhoe pit samples, soil texture is primarily loam or silt loam, but can include <br />silty clay loam Saturation percents range from 42.7 to 52.8 percent for all soil layers, <br />with an average of 48.0 percent, and from 39.1 to 50.6 percent for the mixed and <br />underlying spoil layers, with an average of 42.4 percent. Sodium adsorption ratio (SAR) <br />is all good and ranges from 0.09 to 0.99 (nonsodic) for all samples. Nitrate nitrogen <br />values aze also good for all samples and range from 0.19 to 24.4 with an average of 6.0 <br />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, and lower spoil samples. <br />All selenium and boron values were good with Selenium <0.03 ppm, and Boron <0.87 <br />ppm All ABP values aze positive and range from 12.2 to 106. <br />Six backhoe pits were dug on reclaimed lands -four on the 2W Mine reclaimed land <br />(2WTS-06-P1, 2WTS-06-P2, 2WTS-06-P3, and 2WTS-06-P4) and two on the toast <br />Mine reclaimed land (YTS-06-P1 and YTS-06-P2). The pits were dug down through the <br />reapplied topsoil and into the underlying overburden spoil. The backhoe pits were dug to <br />about six feet in depth, and caze was taken to provide a straight, clean sidewall and <br />endwall for observation, description, sampling, and photographic purposes. <br />A soil profile description was completed in the field and samples were taken by horizons <br />(layers) or depth interval, whichever was most appropriate. Soil profile and landscape <br />photographs of each pit aze attached. The following profile descriptions were completed <br />at the time of soil sampling. <br />toast Mine Reclaimed Land Soil Pit YTS-06-PI (toast Pit 1) <br />Sample site YTS-OS-Pl is located on reclaimed land at the toast Mine. Site <br />chazacteristics include: reclaimed 6% slope on lower upper sideslope position; west <br />• aspect; mixed reclamation grasses and forbs, excellent cover and productivity; reapplied <br />topsoil; well drained; moderate permeability; no erosion at site; sampled July 26, 2006; <br />
