NON -COAL PROCESSING WASTE Salvageable steel, concrete and other construction materials will be removed from the mine site to a salvage yard or regulated landfill, if not needed for portal backfill. Materials will be stored while awaiting removal as shown on Map King II -007. All debris, acid-forming and toxic -forming materials constituting a fire hazard are disposed of by a local waste removal company such as Waste Management. Grease, lubricants, paints, flammable liquids, etc. are stored in the Fuel Storage Building (see Map King II -007) with proper containment and collected on a regular basis by a certified hazardous material collection company such as Safety Kleen. At no time shall any noncoal mine waste be deposited in a refuse pile or impounding structure, nor shall any excavation for noncoal mine waste disposal be located within 8 feet of any coal outcrop or coal storage area. MINE WASTE ROCK DISPOSAL During normal underground mining operations, shale and sandstone break away from the roof and floor of the coal seam. This material was initially removed from the King I mine, and is currently removed from the King II mine and placed in the existing Refuse Pile at the King I mine site (see King I PAP section 2.05.3). Most of the material removed from the King II mine currently originates from the area within OSMRE permit CO -0106A. All mine refuse is being constructed into a Refuse Pile. As of June 2017, approximately 176,000 yd3 exist. Anticipated refuse production from 2017 through 2022 is approximately 5,000 cubic yards per year. The waste bank is currently designed to accommodate up to 1,000,000 yd3. Details of design and construction are given in Appendix 10(1) and are entitled Waste Bank Design Summary Report, November 1993, revised December 1997, by Don R. May, P.E. The location of the mine Refuse Pile is shown on Map King I- 007 and Mine Waste Pile Design, Plan Layout and Detail Sheet. Standard Proctor tests and nuclear density tests will be performed annually as detailed in Don May's aforementioned report to ensure that the waste pile continues to meet the designed compaction requirements. Should different types of strata be encountered during mining, these tests will be repeated to ensure that no significant changes in compaction are allowed. MR -41, "Refuse Pile Sampling Plan", was approved September 22, 2016. This revision consisted of sampling several holes bored into the Refuse Pile, as well as several locations underground in and around the active workings of the King II mine. The report produced using the data obtained from this sampling has been submitted to the Division as MR - 45, and is included in King I Appendix 4(8) GCC Energy, LLC King II Mine Section 2.05.3 Page 9 July 11, 2017 (RN -07)
