Type of Undertaking: Drilling of sixteen core holes for sampling of subsurface coal deposits and the construction of a twin shaft entrance area to underground mine facilities. 11. Size of Undertaking (acres): 15 Size of Project (if different): 75 12. Nature of Anticipated Disturbance: The core holes will impact a small area (up to 50ft x 50ft). First the area will be leveled to accommodate a truck - mounted coring machine, which will test for subsurface coal deposits. Surface vegetation will be removed but the root system will be left when possible. The core hole is small and will impact less than one square foot. A total of 1200ft of existing two -track will need improvement to access core holes CCU15, CCU18 & CCU22. The shaft location will impact an area approximately 300ft x 300ft and a small amount of a new road (500ft) could possibly be built to access the shaft location from the southeast.
