<br />s <br />Given the prior experience with effective <br />methane drainage at the West Elk Mine, it is <br />anticipated that a MDW would be needed every <br />750 feet along each longwall panel in order to <br />meet M5HA approval requirements for the <br />mine ventilation plan. Based on the mine plan <br />configuration with panels extending under <br />portions of the IRA, ventilation plan <br />requirements convey the need to place MDWs <br />and access roads to them in the IRA. <br />The proposed action has been designed to use <br />directional drilling to the maximum extent <br />possible. However, this is limited by the <br />thickness of overburden (or amount of rock) <br />overlying the E seam. This limited thickness of <br />overburden precludes the ability to drill <br />exclusively from outside the IRA boundaries <br />and hit the MDW targets needed in the <br />ventilation plan. Although use of directional <br />drilling opportunities has been used as much as <br />possible, in places the overburden is not thick <br />enough for directional drilling either from <br />outside the IRA to be practical or possible, <br />therefore some of the operations and hence <br />road construction, would be placed in the IRA. <br />Reclamation <br />A plan for reclam <br />through the DRM' <br />reviewed by the Ft <br />would be consisten <br />identified post-minis <br />Forest Plan direct <br />specific reclamatiot <br />analysis.
