12. Although WFC and DRMS claim that the Bench One material is a suitable <br />replacement topsoil, it is actually inferior because it has electrical conductivity <br />levels (a measure of total salt content) which exceed the parameters for prime <br />farmland soils and the levels existing in the native soil. See R. 5430 -531 (Bench <br />One has an EC level of not greater than 6 mmho /cm, as compared to levels not <br />greater than 4 for Lift A material); compare with 7 C.F.R. § 657.5(2)(i)(requiring <br />that prime farmland soils have an EC level of not more than 4 mmho /cm —see <br />definition of prime farmland soils, infra.). <br />13. The Bench One material is inferior to native topsoils (A and B lift) in terms <br />of its rock content. The data relied upon by DRMS shows 25% rock content over 3 <br />inches in size, as compared with no reportable rocks in the native A and B lifts. R. <br />5430. <br />14. The Morgans objected to the use of the Bench One material, stating that it <br />was inferior because of increased rock content and rock size, increased salt content, <br />and stating that this would not produce the crop yields previously existing on the <br />Barx soils. R. 7384. <br />15. OSM engaged in a comprehensive review of PR6 and determined that it does <br />not satisfy state coal regulations because it, inter alia: a) had insufficient data to <br />10 <br />
