Box 535 Somerset, Colorado 81434 USA Tel (970)929-5122 Fax <br />February 10, 2011 (970)929-5177 RECEIVED <br />Mr. Mike Boulay FEB 14 2011 <br />Environmental Protection Specialist Division u3 iw,amation, <br />Colorado Division of Reclamation, Mining and Safety Mining and Safety <br />101 South P, Suite 301 <br />Grand Junction, CO. 81501 <br />Re: Oxbow Minina LLC Permit No C-1981-022 Request for MR 95 Sixteen Angle Boreholes <br />Panels LW-17 and LW-18. <br />Dear Mr. Boulay, <br />Oxbow Mining, LLC requests a Minor Revision No. 95 to Permit C-1981-022. The purpose of the MR is to <br />provide for an additional sixteen (16) angle boreholes. Two angle boreholes are to be located at each of eight <br />(8) approved gob vent borehole (gvb) vertical borehole sites. The angle boreholes are referred to as the "B" <br />and "C" boreholes at the presently approved vertical borehole sites. <br />Panel 17: 17-02B, 17-02C, 17-0513, 17-05C, 17-0613, 17-06C, 17-0813, 17-08C. <br />Panel 18: 18-0213, 18-02C, 18-0413, 18-04C, 18-06B, 18-06C, 18-0913, 18-09C. <br />Oxbow's recent mining activities have entered areas with increasing overburden depth, and therefore, <br />increased methane gas. Recent angle boreholes installed at approved vertical borehole pad sites have been <br />successful in enhancing the drainage of methane. The purpose of the additional boreholes are to enhance the <br />drainage of methane by 1) attempting to intercept NE/SW trending linear joint or fracture features in the <br />overburden and 2) simply close the present spacing of boreholes. <br />We are also including an updated Exhibit 2.04-E3, Geologic Information, Item 9 - Methane Drainage Well <br />Information and an updated Map 2.05-M1, Sheet 6 of 6, General Facilities Gobvent Boreholes. <br />Please contact me at (970) 929-5806 should you have questions or require further information. <br />Sincerely, <br />Ja es A.
