NOTICE OF INTENT TO EXPLORE <br />INVOLVING REMOVAL OF 250 TONS OR LESS OF COAL <br />SPRUCE STOMP COAL EXPLORATION PLAN AREA <br />PAGE 16 <br />erosion, and effects on existing drainages. BRL does not anticipate diversion of any <br />existing drainage as part of this program. Overland (sheet) flow between drainages may <br />be diverted along roadways to the closest down-grade drainage if necessary. New <br />roads will be considered light use roads and will be constructed, maintained, and <br />reclaimed in accordance with §4.03.3. <br />BRL does not anticipate the excavation of sediment ponds, the installation of culverts, or <br />the construction of drainage ditches or other sediment control structures, other than as <br />required to control drainage on and minimize erosion from the new light-use roads to be <br />constructed as part of the proposed exploration program. <br />§2.02.2(2)(g): Methods to be used to conduct coal exploration and <br />reclamation. <br />Drilling Operations <br />BRL proposes to drill 11 exploration holes in the XPA. Holes will be rotary-drilled and <br />nominally five to six inches in diameterto predetermined core points, cased as necessary, <br />and the coal zone cored by PO wireline methods. PQ coring produces a 2.980-inch hole <br />and a 1.875-inch core. Drilling will be with air, air with water injection, or water with <br />synthetic polymer lubricant. Cuttings pits will be necessary at all locations drilled by <br />conventional methods. Locations of proposed holes and new roads required for access are <br />shown on Map 2, Topography & Drill Hole Locations. <br />• Drilling will be accomplished with one of two drill rigs. One atruck-mounted core rig such as <br />a DR 24 or equivalent and struck-mounted rotary rig RD-20 or UDR 2000 or equivalent. <br />The truck mounted drilling rigs will be accompanied by a water truck, typically of 3,000 <br />gallons capacity; aflat-bed service truck; and smaller pickup trucks as necessary for service <br />and transportation to and from the drilling sites. Water will be provided to some of the drill <br />sites via high pressure water line with water pumped from the West and East Forks of <br />Terror Creek with a Bean pump. The Bean pump(s) will be placed in a metal horse trough <br />and located adjacent to Terror Creek. <br />To minimize water truck traffic on dirt roads, water will be pumped with the bean pumps and <br />high pressure water line to every hole that is practical to reach by this method. Where not <br />practical, a combination of pumping to a storage tank then hauling to the hole from the <br />storage tank or simply hauling from a nearby stock pond or creek with a water truck may be <br />required. <br />Some or all of the holes may be geophysically logged. The equipment necessary for such <br />work is typically mounted in a full-size Suburban-type 4 x 4. If only oil-field logging <br />equipment is available, larger trucks, similar in size to a 3,000-gallon water truck, may be <br />required. <br />• Road Construction <br />To the extent possible, BRL intends to utilize existing roads for access and, where available, <br />disturbed sites (wide spots, borrow pits, etc.) for drilling sites. Approximately 1.0 miles of <br />
