2.05.3 Non -Coal Waste Storage Non -coal waste will be stored at the portal levels. Three concrete walls will be constructed to form the storage area. The walls will form a u- shape. The storage area will be approximately 20 feet wide, 30 feet deep and the walls will be 6 -feet high. Commercially available dumpsters may be used in lieu of the concrete structures. Non -coal waste will also be stored in dumpsters located in areas defined in 2.05.3(8). Temporary Gob Piles Gob will be periodically transported from the underground workings on the mine conveyors. At the D -Seam portal transfer tower, gob is transferred to the gob conveyor. The gob is stacked in a temporary gob pile which is located near the transfer tower on the D -Seam. Gob from the B -Seam will be transferred from the transfer tower via steel chute to a concrete gob bin. The gob is then handled by front -end loader and trucks and transported to the permanent gob disposal area. Certain conditions such as inclement weather or severe winter conditions may preclude access to the permanent gob pile for extended periods of time. Therefore, gob may be stored in the temporary gob piles for up to 30 days. Up to 1500 tons may be stored in the temporary gob piles at one time.
