NAPP currently operates one preparation plant and has two preparation plants that have been temporarily idled in response to market conditions. The raw metallurgical coal produced from the mines is trucked to the preparation plants where it is processed or “washed” using conventional coal processing techniques and stored for shipping. All plants have load out facilities adjacent to a rail line. Coal is usually shipped by rail; however, it can also be shipped by truck. All of the preparation plants are located in Somerset County, Pennsylvania. The Cambria Plant has an operating capacity of 325 tons of raw coal per hour, storage capacity for 120,000 tons of clean coal and 180,000 tons of raw coal and load out facilities adjacent to a CSX rail line. The Shade Creek Plant has an operating capacity of 450 tons of raw coal per hour, storage capacity for 120,000 tons of clean coal and 125,000 tons of raw coal and load out facilities adjacent to a NS line.
