The Pennsylvania mining complex, which includes the Bailey Mine, the Enlow Fork Mine and the Harvey Mine, has extensive high-quality coal reserves. The Pittsburgh No. 8 Coal Seam is a large contiguous formation of uniform, high-Btu thermal coal.

The Project is in Marshall County, West Virginia, and Greene County, Pennsylvania within the Appalachian Plateaus physiographic province. The plateau contains an abundance of minable coal. In Marshall County, the Project traverses steep ridges and valleys that are typical of the area (West Virginia Geological and Economic Survey [WVGES], 2020). The underlying bedrock is of Permian or Pennsylvania age (230 to 290 million years ago) and made up of cyclic sequences of sandstone, shale, siltstone, limestone, and coal (WVGES, 2011; Pennsylvania Department of Conservation and Natural Resources [PADCNR], 2020).

The depth of the coal seam along Texas Eastern’s existing right-of-way is approximately 770 feet below the ground surface. Additionally, the Bristoria Wareyard is underlain by a mined panel of a larger active coal mine (Consol Energy Bailey Mine 4L) (Pennsylvania Department of Environmental Protection [PADEP], 2020).

The design of the Pennsylvania mining complex is optimized to produce large quantities of coal on a cost-efficient basis. All of mines utilize longwall mining, which is a highly automated underground mining technique that produces large volumes of coal at lower costs compared to other underground mining methods. Generally the company operate five longwalls and 15-17 continuous mining sections at the Pennsylvania mining complex.

The Bailey Mine, operated by Consol PA Coal Co, is located near Graysville, Greene County, Pennsylvania. The mine is opened by eight shafts and one slope into the Pittsburgh coal seam which averages 69 inches in thickness. The mine produces coal three shifts per day six days per week.

The Bailey mine typically employs six to seven continuous mining units to develop the mains and gate roads for its longwall panels. Coal is transported from the face areas to the section loading point by a chain conveyor on the longwall sections and by shuttle cars on the continuous mining sections. Coal is then discharged onto a series of belt conveyors and transported to the surface preparation plant. Clean coal is transported by unit train to various customers.

The central preparation plant is connected via conveyor belts to each of the PAMC's mines and cleans and processes up to 8,200 raw tons of coal per hour. The PAMC's on-site logistics infrastructure at the central preparation plant includes a dual-batch train loadout facility capable of loading up to 9,000 clean tons of coal per hour and 19.3 miles of track linked to separate Class I rail lines owned by Norfolk Southern and CSX, which significantly increases the PAMC's efficiency in meeting its customers' transportation needs.
