,~ <br />corridor along the north side of an ephemeral tributary drainage to Deep Creek (refer to <br />attached figure), known as Long Draw. The about one mile of new temporary road <br />construction would involve disturbing approximately 1.7 acres, assuming a 14 foot road <br />width. Drill pads will be located within "windows" for their placement shown on the <br />same; figure. Exact placement of the drill pads and road alignments would be made i.n the <br />field to ensure minimal impacts. <br />One of the proposed access routes to the area involves reopening of the abandoned drill <br />acce;~s road to reclaimed sites SOM-53 and 54 (see Section 2.D, Alternative 2). This <br />would involve removing current obstructions that prevent full sized vehicle access, and <br />repairing the road to accommodate drill traffic up to the 14-foot road width. 'Chis would <br />redisturb about 2.5 acres. <br />New temporary road construction will be reclaimed by recontotiring and revegetating <br />once the road is no longer needed. Reopened drill road access would be returned to the <br />condition it was in prior to reopening. <br />All drill holes would be drilled using truck mounted drill rigs. Drilling activities are <br />expected to last approximately 7 to 10 days at each pad location. <br />The GVBs would be: completed on the land surface with a Lamson blower unit. The unit <br />would remain on site until mining has occurred under the GVBs it services, or until <br />mirw~g passes out of the effective range of the blower unit. The GVBs aze arr~mged in a <br />sequence, so that continuous methane liberation is available for the pastel. Each GVB is <br />"active" during the period when the extraction face underground approaches it, passes <br />underneath it, and then passes beyond it. Experience with existing GVBs indicate that <br />they continue to vent methane for several months after the extraction face pas.,es it. <br />Access for at least weekly monitoring would be needed for the life of the GVBs, <br />estimated at this time to be 2 years. MSHA is requiring the needed monitoring for mine <br />safety reasons. Access for required monitoring would be via ATV and/or full--sized <br />vehicle. These GVB would be in use for the extraction of Panel 15, which according'to <br />MCC' is scheduled to begin in January 2002 and be mined until July 2002. <br />After use, each GVEt and exploration drill hole would be plugged and abandoned <br />according to CDMG and USDI-Bureau oFLand Management requirements, azid each drill <br />pad location and access road will be reclaimed. Drill pads, mud pits and access roads <br />would be reclaimed to the extent possible as soon as the drilling activity is completed, <br />with .final full reclamation occurring when the holes are no longer deeded. At the enci of <br />the effective life of each GVB, the blower unit will be removed from the site, the pad <br />location will be recon[oured and revegetated. <br />Water for the drilling operations will be pumped to the drill sites from portable tanks <br />using lugh pressure hose, or maybe transported to the drill sites using mobile water <br />carriers. Water used in the drilling operations will be collected from sources for which <br />MCC has water rights. <br />4 <br />
