II. DESCRIPTION OF UNDERTAHING /PROJECT
10. Type of Undertaking: Drilling of three core holes for the sampling of subsurface coal deposits.
11. Size of Undertaking (acres): 0.3 acres (0.1/hole) Size of Project (if different): 0.7 (0.23/hole)
12. Nature of Anticipated Disturbance: A small azea (up to SOft x SOft) will be leveled to accommodate a
truck mounted coring machine to 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 squaze foot.
13. Comments: Often the terrain does not allow for this amount of surface leveling and the amount of impact
could be less. All the core holes aze accessible via existing two-tracks or overland routes. No dirt work will
occur in association with access to the hole locations.
