OTHER CONSTRUCTION ACTIVITIES <br />Other construction activities planned for the project azea in 2007 may include <br />obliteration of user developed ATV trails. MCC will reclaim these trails as a part of the <br />Sylvester Gulch Road construction. <br />There are three 14-inch pilot holes planned for the Deer Creek Shafts. The <br />purpose of these holes is to further define the strata in the azea of the proposed shafts and <br />to provide a hole that can be re-used as a pilot hole for the raisebore equipment when it is <br />mobilized for the shafts. These would be drilled with the LM-140 drill beginning the 15` <br />of May, 2007 until all three are complete. The holes once drilled would be evaluated and <br />then plugged with a combination of bentonite grout and sand, to be later re-opened by the <br />raise bore machine when the shafts are constructed. <br />DRILLING SCHEDULE <br />MCC will proceed with road construction and drilling activities upon approval of <br />this AOP and in accordance with the Conditions of Approval as referenced in the Forest <br />Service Decision Notice dated May 31, 2002, titled Coal Methane Drainage Project <br />Panels 16-2A Mountain Coal Coanpany IJ'est Elk Miaae. <br />Completion and approval of the Amiual Bird Survey is anticipated by June 9, <br />2007. No new disturbance will occur until after that date. The schedule of drilling is <br />presented based on plans to continue with MDW drilling on the West Flatiron after the <br />pilot holes at the Deer Creek Shafts are completed. The first three MDW drill holes to be <br />completed on the West Flatiron would be completed on an existing drill pad, beginning <br />approximately May 29, 2007. Drilling is presumed to require 8 days per hole including <br />mobilization from site to site, setup, drilling, and rig down. Note: The schedule below <br />is based on using one drilling rig. This schedule is subject to rig availability and/or <br />MCC operating constraints. <br /> 2007 MDW DRILL SCHEDULE <br /> LM 140 <br />Drill Hole Location Duration Start Finish Comment <br />DC-1 USFS-Minnesota Res. 10 5/1/2007 5/10/2007 Includes 2 da.
