No. 5A Mine Conveyor (Overland). Coal produced from the No. 5A/6 Mine was transported by a 48 inch slope <br />conveyor through the No. 5A portal to the 48 -inch Overland Conveyor. The 48 -inch Overland Conveyor transported <br />the coal across State Highway 13 and the Williams Fork River to the Stacking Tube and Primary Raw Coal Stockpile. <br />The Stacking Tube and Coal Stockpile are located near the reclaimed No. 5 Portal Area. Once the overland belt was <br />put in, all coal from the No. 5A Mine longwall system was transported to the facilities area via the No. 5A Conveyor. <br />All coal from the No. 6 Mine is transferred via this same conveyor. The No. 5A slope conveyor leaves the No. 5A <br />Portals and terminates at a Transfer Building which transfers the coal to the 48 -inch Overland Conveyor. <br />48 -inch Overland Conveyor. The 48 -inch Overland Conveyor was constructed in 1985 to allow coal to be transported <br />from the No. 5A Portals to the coal handling facility. Construction of the overland conveyor required approvals from <br />the Colorado Department of Transportation (CDOT) to cross State Highway 13, and from the CMLRD to cross the <br />100 -foot stream buffer zone associated with the Williams Fork River. By documenting that there would be no adverse <br />impacts to either the Highway or River, the required permit and construction approvals were obtained in 1985. <br />Documentation of CDOT approval is presented in Exhibit 19, Overland Conveyor Highway Crossing Approval. The <br />overland conveyor is covered for dust control, and has been included in the MCM Air Emissions Permit. A copy of <br />the Air Emission Permit from the Colorado Department of Public Health and Environment is included in Exhibit 2, <br />Other Required Permits. The 48 -inch Overland Conveyor terminates at the Stacking Tube. <br />Stacking Tube. The Stacking Tube is approximately 85 feet in height and 12 feet in diameter. Coal passes through <br />the Stacking Tube into the Raw Coal Stockpile. <br />Primary Raw Coal Stockpile and Reclaim System. The Raw Coal Stockpile is designed to accommodate over <br />210,000 tons of run -of mine coal. The basal area of the stockpile storage area is approximately 210,000 square feet. <br />The stockpile was constructed on a previously disturbed area and as such, no topsoil was salvaged. Typically, <br />approximately 60,000 tons of coal can be stored in the stockpile. The maximum capacity is used only at times when <br />coal production exceeds delivery schedules. Usually, this will occur when the longwall system is being moved to <br />begin another longwall panel or trains are delayed. A reclaim tunnel is located beneath the Raw Coal Stockpile and <br />the associated conveyor is used to transport the coal from the coal stockpile to the Screening and Sizing Building. The <br />CDPHE Air Emissions Permit and CDRMS approved footprint will dictate the maximum tonnage in the stockpile <br />(Note: There is currently no coal stockpiled at the Mine). <br />30,000 Ton Raw Coal Stockpile. A 30,000 ton coal stockpile, located near the No. 9 Mine Portal, was designed as a <br />supplemental stockpile for low - quality coal trucked from either the primary raw coal stockpile or the 5A Portal. This <br />coal was stored prior to blending, when conditions allowed. This stockpile was removed and the associated area has <br />been reclaimed. <br />36 -inch Overland Conveyor. The 36 -inch Overland Conveyor transports the coal from the Raw Coal Stockpile to the <br />Screening and Sizing and the Sampling Buildings then continues to the 10,000 ton Storage Silo. <br />Screening and Sizing* Building and Samling Building. The Screening and Sizing Building contains the equipment <br />used to screen and size the coal to produce a marketable final coal product. Within the building are screens, a rotary <br />breaker, and associated coal transfer conveyor belts. In the Screening and Sizing Building, coarse reject material <br />(rock) is separated from the coal, and transferred by conveyor to trucks, which haul the reject material to the <br />permitted coal refuse disposal site. Screened and sized coal is then transferred to the 36 -inch Overland Conveyor. <br />Refuse and Lump Coal Bin — A short stub conveyor discharged coarse refuse and over -size coal to a bin adjacent to <br />the Screening and Sizing Building. The refuse was hauled to the permitted refuse pile and employees were allowed to <br />recover the lump coal for home use. <br />TR14 -36 2.05 -10 Revised 09/08/14 <br />
