lists the applicable map unit number, sample numbers, and related information concerning <br /> SCS official soil series descriptions. The SCS descriptions are for the series only, not <br /> the three families of the Haplaquoll great group or the disturbed phases of the Barx <br /> series. The soil series mapped on the Nucla East study area are all established series <br /> (E). <br /> Copies of the SCS Official Soil Series Descriptions, accompanying "Form 5" Soil <br /> Interpretation Records, and profile descriptions of all 72 auger hole soil observations, <br /> are on file at PCC's Western Division office in Flagstaff, Arizona. <br /> Soil series descriptions are provided in Appendix 9-5-3, Soil Profile Descriptions for all <br /> Sampled Pedons, and identify the morphology of representative soil profiles on the study <br /> area. Series descriptions were obtained from sampled soil pedons and have been correlated <br /> with their analytical results as well as with SCS soil series criteria to the extent <br /> applicable. Each soil map unit has a soil landscape photograph. All photographs are <br /> on file at PCC's Division Office in Flagstaff, Arizona. <br /> Soil Laboratory Results. The results of laboratory analysis of all soil samples collected <br /> during the 1987 and 1988 soil surveys are provided in Appendix 9-5-4, Soil Laboratory <br /> Data. A detailed discussion of the chemical and physical properties of each soil type is <br /> included in the Topsoil Management Plan section of Tab 21 (Minesoil Reconstruction). <br /> Inter-Mountain Laboratory (IML) routinely reruns about 10 percent of all samples as part <br /> of the quality assurance program. In addition, reruns are performed on certain parameters <br /> significant to soil classification or for which the initial data was either borderline or <br /> suspect. Rerun values were very similar to original values. For quality control, six <br /> samples were also sent to Peabody Central Laboratory (PCL) in Freeburg, Illinois for <br /> either partial or complete analysis. All replication data values are presented in <br /> Appendix 9-5-4, Soil Laboratory Data. <br /> Data values between labs were generally quite similar, with the following differences <br /> noted. PCL had paste pH values, on average, 0.3 units higher than IML. No particular <br /> reason for this discrepancy can be found at this time. This difference is sufficient to <br /> change the first lift/second lift suitability interpretation for three Barx samples (Site <br /> 7), one Mivida sample (Site 9), and one Bowdish sample (Site 40). However, this 0.3 unit <br /> pH discrepancy will not influence first lift/second lift topsoil handling plans presented <br /> 9-5-27 Revised 08/19/88 <br />
