NOTICE OF INTENT TO EXPLORE PAGE 11 INVOLVING REhIOVAL OF 250 TONS OR LESS OF COAL STOVE CANYON COAL EXPLORATION PLAN AREA I ~ §2.02.2(2)(8): Methods to be used to conduct coal exploration and reclamation. Drilling Operations CAM proposes to drill 9 exploration holes in the XPA. Holes will be rotary-drilled and nominally five to-six inches in diameter to predetermined core points, cased as necessary, and the coal zone cored by PQ wireline methods. PQ coring produces a 2.980-inch hole and a 1.875-inch core. Drilling will be with air, air with water injection, or water with synthetic polymer lubricant. Cuttings pits will be necessary at all locations drilled by conventional methods. Locations of proposed holes and new roads required for access are shown on Figure 1, Index Map. Drilling will be accomplished with two drill rigs. Atruck-mounted core rig such as a DR 24 or equivalent and atruck-mounted rotary rig RD-20 or UDR 2000 or equivalent. The truck mounted drilling rigs will be accompanied by a water truck, typically of 3,000 gallons capacity; aflat-bed service truck; and smaller pickup trucks as necessary for service and transportation to and from the drilling sites. Water will be imported. Some or all of the holes may be geophysically logged. The equipment necessary for such work is typically mounted in a full-size Suburban-type 4 x 4. If only oil-field logging equipment is available, larger trucks, similar in size to a 3,000-gallon water truck, may be • required. Road Construction To the extent possible, CAM intends to utilize existing roads for access and, where available, disturbed sites (wide spots, borrow pits, etc.) for drilling sites. Approximately 1.8 miles of new road construction and 1.7 miles of reclaimed road re-construction will be required if all 9 holes shown on Figure 1, Index Map are drilled. These road segments are also shown on the referenced map. Road construction and reclamation will be in accordance with applicable standards of the BLM for temporary access roads and with performance standards of the Division of Minerals & Geology for light-duty roads (§4.03.3). Access roads will be constructed using a Caterpillar D-9 class tractor-dozer where necessary and a D-5 class tractor-dozer or equivalent or smaller track -mounted bulldozer, and aproportionally-sized backhoe such as a John Deere 410C where possible. The reclaimed roads to be reestablished were constructed for coal exploration purposes. CAM does not anticipate any blasting during the proposed exploration program. Excavated Earth And Debris Disposal Topsoil will be removed from drill sites and new roads and stored for use in reclamation in accordance with applicable portions of §4.06. Drill cuttings, if any, will be shoveled into the holes during sealing, scattered around the drill site before reclamation, or both.
