portion of the permit area, with map unit boundaries depicted, although the area <br />appears to be located outside any of the soil survey boundaries. Please revise the <br />map to clarify the survey upon which the soil mapping in this area was <br />based. <br />13. Page 2.04.9-24 through 2.04.9-28 includes soil balance narrative and related <br />Tables 2.04.9-5 and 2.04.9-6. New Map 2.04.9-2 "Topsoil Balance Map As Of <br />February 2008" was submitted in addition to the narrative and tables. We have the <br />following questions regarding this information. <br />a) Map 2.04.9-2 depicts current status (location, type of soil, and volume) of <br />topsoil stockpiles. Location of any additional proposed soil stockpiles should also <br />be provided on a map (either amended Map 2.04.9-2) or an additional permit area <br />map. Also projected maximum volume of each existing and proposed stockpile <br />should also be indicated (either on tables or maps). Please submit the requested <br />information, or provide reference if the correct information is included on <br />approved permit area maps or tables. <br />b) Table 2.04.9-6 indicates that for the Morgan property that has not yet been <br />disturbed, an average 40 inch thickness of subsoil material will be salvaged <br />(referred to as "Lift B + Suitable Subsoil" on Table 2.04.9-6). Please address <br />what differentiates Lift B material from "suitable subsoil" material, and how the <br />bottom of Lift B is defined for the purposes of field operations. Presumably, the <br />"suitable subsoil" is essentially synonymous with "Bench 1" overburden, which is <br />the unconsolidated deposits immediately underlying the native subsoil. Will the <br />Bench 1 material be salvaged and replaced separately from the "Lift B" soil <br />horizons, or will some thickness of unconsolidated overburden (as necessary to <br />obtain a total 40" "subsoil" recovery thickness) be included in Lift B recovery <br />operations. Please provide appropriate narrative clarification regarding <br />delineation, recovery, and handling of rootzone material beneath Lift A, for <br />the undisturbed portion of the Morgan property prime farmland. <br />c) Narrative on page 2.04.9-23 indicates an average Lift A thickness of <br />approximately 7.2 inches for the non-prime farmland soils north of BB Road, <br />which seems reasonable based on the survey data for the dominant soil types. <br />However, this does not correspond with Table 2.04.9-6 entries for the 16.67 acre <br />"Lloyd Undisturbed" property and the 87.76 acre "WFC Undisturbed" property, <br />both of which indicate an 18" Lift A thickness. This apparent inconsistency may <br />be a semantic artifact, with "Lift A" being used to mean two different things (in <br />one case referring to the A and upper B horizons, and in the other case referring to <br />the top lift that would be removed, including A, B, and C horizons mixed). It <br />would appear to be intended that an average 18" mixed soil layer would be <br />recovered in a single lift from these areas, with a separate lower lift consisting of <br />Bench 1 overburden material, but the wording is confusing. Please clarify the <br />issues regarding salvage lifts and thicknesses (for soil horizons as well as <br />underlying Bench 1 overburden) for the non-prime farmland areas, and <br />5
