10' high. The building foundation will consist of a 12" thick poured-concrete floor supporting 8" thick, 3" tall <br />• poured-concrete stem walls. <br />The batch weigh/loadout building will be asteel-framed, metal-sheathed building set on sixteen (16) 48-inch <br />diameter caissons placed on bedrock. The building will straddle the railroad tracks approximately 250 feet east of <br />the existing Tipple 2 stockpile and loadout. Dimensions of the building will be 28' x 40' x l 1 I' high. Drill rig <br />access to the site of the batch weigh/loadout building for caisson installation will be provided by either driving <br />along the railroad tracks or utilizing the new proposed access road east of the existing Tipple 2 coal stockpile (see <br />Map 24). <br />A washdown water drain line will be constructed from the west side of the batch weigh/loadout building to Pond C. <br />The drain line will be a PVC pipe mounted on a set of three support poles and sloped to drain. The pipe will be <br />designed to convey the quantity of washdown water expected to be applied to equipment inside the building. The <br />locations of the support poles aze shown on Map 24 under the label "Batch Weigh Drain Line". <br />A crane situated at the base of the new access road to the site will be utilized to facilitate construction of the batch <br />weigh/loadout building. Construction materials for the batch weigh/loadout building will be laid on the existing <br />haul road (south of the construction site) or the newly constructed access road, either of which will be utilized as <br />staging areas. Operations access to the batch weigh/loadout building following construction will be provided either <br />by the new access road or by driving along the railroad tracks. <br />The site for the batch weigh system coal stockpile will require minor excavation into the slope on the eastern <br />margin of the pile. The majority of the proposed batch weigh system coal stockpile site has been previously <br />disturbed. The existing toe of the hill slope will be moved eastward approximately 100 feet from its current <br />location, then laid back to a 2H:1 V slope. The excess excavation volume for this work is estimated to comprise <br />• approximately 12,000 cubic yards. The excavated material will either be stored adjacent to the site by re-spreading <br />to provide a uniform surface and to create uniform drainage from the site toward Ditch D-1 or will be utilized as <br />permanent fill in the relocation of County Road 27 as detailed in TR-19. If the materials are stored on site, they <br />will be re-spread in the area between the batch weigh system coal stockpile site and the existing road southwest of <br />the site to provide uniform surface and to create uniform drainage from the site toward Ditch D-1. Following <br />construction, the materials will be seeded and stabilized in accordance with the approved reclamation plan <br />provisions. In the event the materials are utilized as fill for CR 27, TCC will replace an equivalent volume of <br />material at the batch weigh coal stockpile site during final reclamation. The replacement material will consist of <br />spoil obtained during regrading operations in the area south of the existing portals and associated facilities at the <br />Foidel Creek Mine. The volume of replacement material potentially required (maximum 13,500 cubic yards) will <br />have no discernible impact on the final re-grade configuration proposed for the source area described. <br />Ditch D-1 will re re-routed slightly to the north as shown on Map 24. The batch weigh system coal stockpile and <br />surrounding area will be graded to slope towards Ditch D-I, which will proved perimeter sediment control for the <br />area and will route runoff from the site to Pond D. <br />Site configuration will require the batch weigh system coal stockpile to cover Ditch D-1 along the northern margin of <br />the stockpile for a distance of approximately 440 feet. In this area, Ditch D-1 will be routed through a 24-inch diameter <br />CMP culvert beneath the stockpile or through a combination of culverts providing the same hydraulic conveyance <br />capability. This culvert size was selected based upon a revised evaluation of Ditch D-l design <br />• <br />f,1pp~8~~iJ~IJ APR E 4 2000 <br />Permit Renewal No. 3 2.05-57 12/10/98 <br />
