<br />TAB 1 & <br />BACKFILLING AND GRADING <br />Introduction <br />The loadout area was originally disturbed by construction activities during [he time <br />period 1978 - 1979. The majority of the earthmoving operations were conducted as a direct <br />result of the grade requirements for the railroad spur. The topography of the land prior <br />to construction was such that construction of the spur required much mare cu[ than it did <br />fill. The following discussion regarding backf illing and gr din9 is limited [o those <br />areas disturbed due to constrvction and will be graded only when the loadout is no longer <br />needed. <br />Timing of Backfilling and Grading <br />The loadout area and railroad spur will be graded in conjunction with closure or final <br />reclamation of the facility. This date has not yet been determined Isee Tab 17, <br />• Reclamation Schedule). <br />Method for Backf illing and Grading <br />To the extent possible, most oradin9 will be conducted by dozing material into [he cut <br />areas. This will leave a Swale that has positive drainage Isee Exhibit 18-1). This is <br />not inconsistent with the post mine land use of pasture land. Leaving an undulating <br />topography will also be of benefit to wildlife as escape and thermal cover. Please refer <br />to Exhibit ]8-2 for pre- and post-opera [i onal cross sections. <br />Disturbance beyond the existing disturbance boundary to backfill or slope certain areas to <br />an acceptable grade may be necessary. Pri oz to this operation, if topsoil exists in [his <br />area, it will be salvaged prior to disturbance. Depending on the location, the topsoil <br />may be pushed back out of the way or picked up and stockpiled or redistributed. <br />After the buildings and coal conveyance eouipment has been removed, the area will be <br />graded to blend into [he surrounding topography (Exhibit 18-1). <br />• please refer to Tab 23, Bonding, for specifics pertaining to demolition, disposal, <br />1 Revised 03!01 /93 <br />
