NOTICE OF INTENT TO EXPLORE INVOLVING REMOVAL OF 250 TONS OR LESS OF COAL JEEP TRAIL COAL EXPLORATION PLAN AREA PAGE 14 • topsoil so removed and stored will not be used for reclamation during the fall, it will be seeded with afast-growing annual such as rye grass to minimize erosion during spring snowmelt. Existing roads will be graded (if necessary) and new roads and drill pads will be constructed in such a manner as to minimize grades, cuts and fills, overland flow erosion, and effects on existing drainages. BRL does not anticipate diversion of any existing drainage as part of this program. Overland (sheet) flow between drainages may be diverted along roadways to the closest down-grade drainage if necessary. New roads will be considered light use roads and will be constructed, maintained, and reclaimed in accordance with §4.03.3. BRL does not anticipate the excavation of sediment ponds, the installation of culverts, or the construction of drainage ditches or other sediment control structures, other than as required to control drainage on and minimize erosion from the new light-use roads to be constructed as part of the proposed exploration program. §2.02.2(2)(8): Methods to be used to conduct coal exploration and reclamation. Drilling Operations BRL proposes to drill 2 exploration holes from one drill site in the XPA. The holes will be • rotary-drilled, nominally nine to ten 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. Locations of proposed holes and new roads required for access are shown on Map 2, Topography & Drill Hole Locations. Drilling will be accomplished with one of two drill rigs. One 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 provided to the drill site or an intermediate frac tank via high pressure water line with water pumped from Terror Creek Reservoir with a Bean pump. The Bean pump will be placed in a metal horse trough and located adjacent to the reservoir as denoted by "P1 " on Map 2, Topography & Drill Hole Locations. This will minimize water truck traffic on dirt roads. At least one of the holes will 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.
