12 inches for "A" horizon materials with approximately 13,800 cubic yards of <br />"A" horizon material placed in stockpile M•3, and 24 inches for 'B" horizon <br />materials with approximately 13.100 cubic yards of "B" horizon material <br />placed in Stockpile M-2. <br />r~eura <br />:~ ~:s <br />As placement of coal refuse continued and the refuse stockpile advanced to <br />the west. EFCI recovered topsoil to a depth of approximately four (4) feet <br />from the foundation area. Approximately 70,000 cubic yards of "A" and "B" <br />horizon soil materials were separately recovered and directly replaced on <br />regraded stockpile areas. Replacement depths approximated recovery depths <br />averaging four (4) feet. with separate handling and placement of soil <br />horizons. <br />As mining and related operations corrtinue and the coal refuse stockpile <br />advances to the west, EFCI will recover all topsoil contained in the <br />remaining undisturbed areas within the footprint of the previously designed <br />refuse pile (7.3 acres). To the extent passible, this material will be live <br />handled. Some material may have to be temporarily stored in Stockpile M-4 <br />which will be located on top of the refuse stockpile. The amount stored in <br />M-4 will vary depending on how much soil can be live handled and the amount <br />of area available on top of the refuse stockpile. <br />When Dorchester developed the loadout area near Florence, topsoil resources <br />were recovered and stockpiled from all disturbance areas except along the <br />railroad right-of•way and same adjacent areas which had previously been <br />disturbed. Average recovery depth of 6 inches, over the total disturbance• <br />area of approximately 7.1 acres in the eastern portion of loadout. yielded <br />6.000 cubic yards of topsoil which was placed in Stockpile L•1 south of AT&SF <br />railroad cut. Average recovery of approximately 7 inches of topsoil over the <br />B.0 acre western loadout disturbance area, resulted in placement of <br />approximately 6.000 cubic yards of soil material in Stockpile L-2 located <br />just south of the county road. A recent review of topsoil and refuse <br />suitability characteristics indicates that the upper 12 16 inches of the <br />soil profile represent the best material for use as a revegetation medium. <br />Revised 5/13/04 <br />Permit Renewal RN-04 <br />2.05.3.57 <br />
