The Consolidation Coal Co. (CCC) affiliate of Murray Energy applied in September with the West Virginia Department of Environmental Protection for an air permit covering a plan to bring coal combustion waste to the McElroy longwall mine for disposal.
McElroy is one of several longwall mines working the Pittsburgh coal seam in northern West Virginia that Murray Energy bought in late 2013 from CONSOL Energy (NYSE: CNX).
McElroy operates a coal preparation plant located in Marshall County near Moundsville, West Virginia. With this application, CCC is requesting authorization to construct a conveyor system and river unloading facility to handle coal combustion product (CCP) at the McElroy Facility.
The application said a barge-mounted crane will be used to unload CCP from barges. The CCP will be conveyed to a truck bin via a series of four conveyors. The truck bin will then dump into haul trucks. The haul trucks will transport the CCP to the existing refuse disposal areas. With this project, CCC is proposing to install the following equipment: four conveyors, each rated at 1,600 tons per hour (tph); one refuse truck bin; and one barge mounted crane for unloading barges.
The McElroy Facility is an active bituminous coal underground mine. The coal is procured from an existing mine portal and is conveyed to two raw coal storage silos. From the raw coal storage pile, coal is conveyed to a screening tower, where the raw coal is screened and separated into two distinct material streams: the refuse stream is crushed, conveyed to refuse storage bins, and ultimately transported to refuse storage piles; and the “plant feed” coal is conveyed to a silo and ultimately transported to the preparation plant.
Two types of material exit the preparation plant. The first type is refuse. The refuse is conveyed to a refuse storage bin and ultimately transferred to the refuse storage piles. The second type of material is clean coal, which is raw coal that has been screened, sized, and washed in the prep plant. Clean coal is conveyed to the clean coal storage bin and ultimately transferred to the barge loadout area, the application said.
Startup of the CCP operation is planned to begin on or about Jan. 1, 2017.
