Because of this <br />concern, MSHA is mandating the installation of gob vent boreholes to vent methane from <br />subsided long wall panel areas (gob). OMLLC anticipates the MSHA concerns will <br />dictate an ongoing program to install such boreholes into each successive panel of the Elk <br />Creek mine. <br />OMLLC has previously permitted initial programs (TR-46, 48 and 53) of twenty (20) gob <br />vent boreholes. The subject of this TR is to install eleven (11) additional boreholes and <br />associated light use roads. These particulaz activities will be conducted on US Forest <br />Service lands. The USFS has initiated their NEPA process with a Public Scoping Notice <br />dated March 13, 2006. The proposed program is summarized by the attached information. <br />Revised PAP text pages 2.05-31a and 2.05-SOa are attached to address this proposal. <br />Map 2.05-M1-General Facilities, sheet 6 of 6 is provided showing the location of the <br />additional sites. <br />A revised Exhibit 2.04-E3, Item 9 -Methane Drainage Well Information is included <br />summarizing the GVB program. <br />3737 Hwy 133 P.O.
