RULE 2 - PERMITS Structure - The upper horizon in both sample pits is moderate coarse and very coarse platy and sub- angular blocky. The resultant structure and depth of the structure is consistent with a mechanically disked layer but is moderately compacted. The lower topsoil horizon is strong coarse and very coarse sub - angular and angular blocky structure. This indicates moderate compaction. Vegetation analysis discussed below did not indicate that such structure is presenting a problem to plant growth. Consistence - The dry consistence of the upper soil layer is hard. Moist consistence is friable. Consistence of the lower soil horizons is higher than typical for textures of loam. Dry consistence is very hard. Dry consistence indicates moderate compaction through the use of mechanical equipment for soil redistribution. Moist consistence is friable to firm. Vegetation analysis discussed below did not indicate that such consistence is presenting a problem to plant growth. Lab Results - Both the upper and lower soil horizons, differing only in their mechanical treatment, have the same chemical properties. The pH ranges 6.3 to 7.0 and averages 6.8 which is neutral. Organic matter averages 4.5 percent and ranges 3.5 to 8.6. These results and all other lab data indicate topsoil in all sample pits is suitable. Representative subsoil results: Depth - The average depth to the start of subsoil is 10.7 inches (0.9 feet) below the surface. Depth to subsoil ranges seven to 19 inches (.6 to 1.5 feet). Sample site S2 -01 -3 occurs over bedrock at a depth of 24 inches indicating that this site only had surface disturbance. • Textures - Textures are loams, clay loams, and clays. Clay content averages 28 percent and ranges 15 to 44 percent, sand content averages 39 percent and ranges 18 to 44 percent. Silt content averages 33 percent and ranges 30 to 36 percent. Rock Fragments - Rock fragments average 25 percent and range five to 45 percent. Rock Fragments are predominantly gravel and cobble size (2mm to 250mm) of sedimentary origin, primarily sandstone. Structure - Structure of the subsoil is strong very coarse subangular blocky. Such structure is typical of mechanically redistributed subsoil. Consistence - Dry consistence in the subsoil layer is very to extremely hard. Dry consistence indicates moderate compaction through the use of mechanical equipment for subsoil redistribution. Moist consistence is firm. Lab Data - The subsoil pH ranges 6.3 to 7.6 and averages 7.0 which is neutral. Organic matter averages 4.5 percent and ranges 1.1 to 5.8. These results and all other lab data indicate subsoil in all sample pits as suitable. 2009 Site - Specific Soil Sampling and Analyses Soil map unit boundaries were delineated in the 2009 Order I Soil Resource Survey of the PSCM by • observing surface conditions, vegetation, slope gradient and aspect, geology, and soil profiles exposed using a sharpshooter spade and bucket auger. All major soils mapped in the potential PSCM PSCM Permit App. 2.04 -125 6/15/09
