-41- <br /> additional disturbance to trees, grass, and stable soil conditions. The minor <br /> revision approval allows Western Fuels to leave the top of the cut slopes in <br /> their present configuration, except where a large area will drain over the cut <br /> slope face, resulting in excessive erosion. At these locations, a ditch will <br /> be cut along the top of the cut, as previously defined in the permit, to <br /> intercept runoff and channel it into the ditch located along the road. <br /> The only stream channel which will be disturbed by the backfilling and grading <br /> operations will be Scullion Gulch. The stream will be returned to its <br /> approximate original meander pattern and gradient during the reclamation <br /> operation. For further details, see the Surface Water Section- of this <br /> findings document. <br /> Backfilling and grading of the surface facilities will occur upon the <br /> completion of mining which is as contemporaneous as feasible. Disturbed areas <br /> which will not be redisturbed during mining operations or final regrading will <br /> be backfilled, regraded and revegetated as part of the original construction <br /> work (page V-30). <br /> There should be no excess spoil permanently disposed of according to the <br /> backfilling and grading plan proposed for the reclamation of surface <br /> disturbances. Excess material from the D-Portal Area excavation is presently <br /> stockpiled in a life-of-mine storage area or "blister" situated along the <br /> eastside of the D-Portal access road as shown on Map 56. This material will <br /> be replaced during final reclamation to return the D-Portal Area to AOC. <br /> The operation is in compliance with the requirements of this section. <br /> XVIII. Coal Processing Waste and Non-Coal Processing Waste - Rules <br /> , and 4.11 <br /> Information pertaining to the handling and disposal of coal processing waste <br /> generated by the mining operation is presented in Section IV. D, pages IV-33 <br /> through IV-36 of Volume 4 of the permit application. Map 76 shows the <br /> location of the eleven refuse disposal areas to be developed over the life of <br /> the mine. Map 77 shows the configuration of the first four subareas to be <br /> developed during the current permit term. The reclaimed configuration of the <br /> first four subareas is shown on Map 81 . A discussion regarding the handling <br /> and disposal of non-coal wastes is provided in Section IV. D, pages IV-32 to <br /> IV-33. <br /> Coal Processing Waste Disposal <br /> The permittee is disposing of coal processing wastes and mine development <br /> wastes in a refuse pile located in the northeastern section of the mine plan <br /> area. This area is moderately sloping with the average slope of the profile <br /> of the valleys from the toe of the proposed fill to the top of the proposed <br /> fill being less than 10 degrees. No springs or perennial water courses exist <br /> in the area and ground water was not detected down to 44 feet. Coal <br /> processing wastes, amounting to approximately 450,000 tons per year, will <br /> consist of roof and floor 'rock, interburden and some coal . The development <br /> waste is material excavated during the construction of portals and entries to <br /> the mine. The wastes do not contain quantities of toxic or acid forming <br /> materials to create an acid or toxic leachate. This determination is based on <br /> the results of overburden analysis of waste material submitted to the <br /> regulatory agencies duringlIthe permit review period. <br />
