Soil samples will be obtained from <br />both the native horizons and at predetermined sampling intervals. The predetermined <br />sampling intervals will be 0 to 6, 6 to 12, 12 to 18, and in 18 inch increments to 54 inches. From <br />the 54 to 72 inch depth, the samples will be obtained from the pit face for the 54 to 60 inch <br />depth and using a bucket auger for the final 12 inches. The samples from both the pit face (54- <br />60 inches) and bucket auger (60 -72 inches) will be thoroughly mixed and a subsample will be <br />obtained for laboratory analysis. <br />Soil sampling locations will be determined by randomly placing georeferenced sample locations <br />prior to going to the field (see Map 2.04.9 -3). However soil sampling locations may be modified <br />by a Certified Professional Soil Scientist or Certified Professional Agronomist in the field based <br />on plant growth, topography, and other site specific conditions. Additional pits may be added <br />in the field based on the observations made in the test pits shown in the attached figure. <br />Reclaimed Areas <br />Key Agricultural Services, Inc. <br />The reclaimed area soil resource will be visually evaluated and sampled using traditional soil <br />test pits. Within the permit area approximately one test pit will be excavated with a backhoe to <br />a depth of 60 inches at multiple locations in the reclaimed areas. At each soil test pit a soil <br />profile description will be performed in accordance with USDA protocols. Soil samples will be <br />obtained from three sample sites shown on Map 2.04.9 -3. Soil samples will be obtained from <br />both the redistributed topsoil and subsoil horizons and at predetermined sampling intervals. <br />The predetermined sampling intervals will be 0 to 6, 6 to 12, 12 to 18, and in 18 inch increments <br />to 54 inches. From the 54 to 72 inch depth the samples will be obtained from the pit face for <br />the 54 to 60 inch depth and using a bucket auger for the final 12 inches.

Additional pits may <br />be added in the field based on the observations made in the test pits shown in the attached <br />figure. <br />Stockpiled Soil Resource Evaluation <br />Approximately five or 10 borings (based on the size of the stockpile) were randomly placed <br />across the salvaged and stockpiled material for each stockpile. The borings will be conducted <br />so that the entire depth of the material is evaluated. The soil borings will be performed using a <br />Geoprobe® (or similar device) direct push device. Four samples from each boring will be <br />Page 3 <br />
