%�1M <br />Non -Coal Waste Storaae <br />Non -coal waste will be stored at the portal levels. Three concrete walls will <br />be constructed to form the storage area. The walls will form a u- shape. The <br />storage area will be approximately 20 feet wide, 30 feet deep and the walls <br />will be 6 -feet high. Commercially available dumpsters may be used in lieu of <br />the concrete structures. Non -coal waste will also be stored in dumpsters <br />located in areas defined in 2.05.3(8). <br />Temporary Gob Piles <br />Gob will be periodically transported from the underground workings on the <br />mine conveyors. At the D -Seam portal transfer tower, gob is transferred to <br />the gob conveyor. The gob is stacked in a temporary gob pile which is <br />located near the transfer tower on the D -Seam. Gob from the B -Seam will <br />be transferred from the transfer tower via steel chute to a concrete gob bin. <br />The gob is then handled by front -end loader and trucks and transported to <br />the permanent gob disposal area. Certain conditions such as inclement <br />weather or severe winter conditions may preclude access to the permanent <br />gob pile for extended periods of time. Therefore, gob may be stored in the <br />temporary gob piles for up to 30 days. Up to 1500 tons may be stored in the <br />temporary gob piles at one time. <br />Gob Bin <br />Concrete structure, 15 feet wide, 30 feet long with 8 foot walls open on the <br />top and end for front end loader access. Located on B- Bench. <br />Rock Bin <br />Concrete structure located on the D- Bench. The structure has an 18 -inch <br />thick back wall that is 8 -feet high and 23 -feet wide. The 12 -inch thick side <br />walls are 7 -feet high and 15 -feet long. The 12 -inch thick floor is 23 -feet wide <br />and 16.5 -feet long. Constructed in 2014. <br />Rock Dust Storage Areas <br />The D -Seam portal bench and the B -Seam portal bench will have steel rock <br />dust silos approximately 50 feet high and 8 feet in diameter. A cinderblock <br />building under the silo, which houses a rock dust pod and a distribution <br />compressor is approximately 30'X 20'X 8'. <br />Pump House <br />A pre- engineered metal building designed to house the pump station which <br />supplies water to the mine operation.
