Chapter II <br /> c. Non-Coal Refuse Disposal. <br /> Pion-coal waste will be handled and disposed in accordance with <br /> CMLRB regulations, section 4 . 11.4 - Disposal of Non-coal Waste. <br /> (1) Solid Non-coal Waste Disposal. <br /> Solid non-coal waste will be disposed in the approved solid waste <br /> disposal sites, which are situated at the toe of the rock tunnel <br /> fill, and at the No. 1 mine portal area. <br /> Waste material in the disposal areas will be regularly covered over <br /> with non-combustible material, and compacted. Coverage and <br /> compaction will be done at least annually, and will take place when <br /> ground conditions are dry. <br /> Generally, the schedule for coverage and compaction will be after <br /> snowmelt, and again before snowfall. This schedule may vary <br /> according to ground conditions, so that coverage and compaction is <br /> not done when the ground is wet or snowcovered and frozen. <br /> During the summer season of 1992, some of the soil material removed <br /> during road maintenance, including materials from ditches, material <br /> from b.a.t. ponds, material excavated during replacement of <br /> culverts or construction of rolling dips will be placed on the No. <br /> 1 Mine refuse disposal area. The refuse disposal area was covered <br /> with 2 feet of non-combustible material during 1987 , then <br /> compacted. Some additional soil material was added during 1991, <br /> and compacted. In the fall of 1992, this refuse disposal area will <br /> be seeded and mulched. <br /> During 1991, the operator began a general clean-up program, which <br /> included removal of scrap metal, including non-essential metal <br /> structures. The operator will continue with removal of scrap metal <br /> and general clean-up. Work at the portal areas, including <br /> demolition or repair of structures damaged by the elements, will be <br /> carried out according to the following schedule: <br /> - No. 5 Mine = 1993 . <br /> - No. 4 Mine = 1994. <br /> - No. 3 Mine = 1995. <br /> ( 2) Liquid Waste Disposal. <br /> Wastes such as grease, lubricants and oils used in the shops will <br /> be stored temporarily at the truck shop which is near the <br /> preparation plant area. Periodically, they will be removed from <br /> the permit area and delivered to an outside contractor for refining <br /> and subsequent use. <br /> 44 Revised 12/91 <br /> TR-24 <br />
