As we discussed, the proposed changes will facilitate upcoming reclamation activities. The revisions include plans to dispose of coal stockpile base material in backfilled azeas, and an incidental boundary change. Following aze descriptions and detailed information about the revisions. Request for a Minor Revision (MR-33): Disposal of Stockpile Base Material at Coal Loadout EFCI proposes to place and dispose of coal stockpile base material, consisting of mixed coal and soils, into backfill areas during reclamation operations. The base material will be placed at the bottom of the backfill in both loadout areas. As we discussed in the field, this base material will be covered by a minimum of four (4) feet of suitable cover. EFCI estimates that approximately 5,000 LCY of base material will be moved at the loadouts based its current footprint area of 10.3 acres, and thickness of 2 to 4 inches. There is adequate space available in the azeas to be backfilled to place and cover the base material, and achieve the postmining topography shown on Map 29 of the permit application. The approximate footprint of the areas where the base material will be phtced and covered is shown on attached Figure 1, Loadout Area. In the west loadout area, the base material will be placed partially within the Oak Creek alluvial valley floor (AVF) area. In accordance with the reclamation plan described in the AVF assessment report (Kaman Tempo, 1983) found in Exhibit 24 of the permit, the proposed placement of base material covered with 3 feet of suitable material and 1 foot of topsoil will restore the essential hydrologic function. >n addition, the proposed reclamation plan will adequately restore the AVF soil characteristics as required by Stipulation No. 4 of the permit application.
