BRL does not anticipate encountering any significant aquifers in the course of the proposed exploration program. Method for Plugging Drill Holes • Holes not completed as surveillance, gob vent holes or monitoring wells will be sealed using cement or other approved sealant from total depth to within three feet of the surface. Drill cuttings may be mixed with cement or other approved sealant during sealing. Holes will be marked with afour-foot (minimum) steel roof bolt or a T-shaped fence post. Sealing will be in compliance with §4.07.3. That portion of the hole between the cement seal and the [reclaimed] ground surface will be filled with dirt, drill cuttings, or both to minimize hazards to wildlife, livestock, and humans. Plans for Transfer and Modification of Exploration Drill Holes to Be Used as Surveillance, Monitoring, or Water Wells The operator will modify both of these holes into gob vents. §2.02.2(2)(h): Endangered or Threatened Species The road and drill site proposed for this Jeep Trail XPA was surveyed during the environmental assessment for the Alder Creek Exploration Plan, COC-66126, NOI CX- 2002-08. Alder Creek Exploration Hole IP2001-21 aka IP2001-1 is in the same location as proposed Jeep Trail exploration hole JT-1.
