8.1.7 Replaced Soil Resources Sampling Details Remediation Procedures and Renortinn <br />All Prime Farmland Lift A and B as well as single lift soils will be tested according to the <br />parameters outlined in Table 2.05A(2)(d) -1. Sample frequency is as shown in the table for each <br />aterial type. Any sample point that exceeds a criterion will have four additional samples <br />obtained from 150 feet away from the sample point along the grid lines analyzed for the <br />exceeded criterion If any of these four samples also exceed the same criterion additional <br />samples will be taken to delineate and define the area out of compliance and the suspect <br />material will be either a) removed and replaced with sufficient thickness of suitable material to <br />ensure that any remaining unsuitable material is at least 8 feet below the final surface or b <br />backfilled with additional suitable material so that the unsuitable material is at least 8 feet from <br />the final surface. If none of the additional samples exceed the criterion no further action will be <br />taken. <br />Prior to distribution of topsoil all graded mined areas (on which topsoil is to be applied) will be <br />sampled to confirm spoil suitability (see Overburden /Spoil Handling Plan for more details) The <br />density and physical characteristics of the replaced topsoil and upper spoil will be observed <br />Past experience has shown that ripping and chisel plowing will correct any excessive <br />compaction problems. The minimum sampling intensity shall be one hole per moo unit or five <br />acres whichever is less Depth measurements shall be taken at the same locations as the <br />original sample sites. Replacement depth information shall include separate thicknesses of Lift <br />A and Lift B for those areas (prime farmland) where the 2 lift replacement aoolies This topsoil <br />salvage and replacement depth information will be kept on file at the mine office and will be <br />submitted with the Annual Topsoil Balance /Spoil Quality Report Topsoil recovery depths will <br />be adjusted if warranted by the site conditions <br />(Revised October 2009) 2.05.4(2)(d) -23 <br />
