This MR provides for an additional utility borehole to be located at the pad site of the VB-1 S-01 <br />ventilation borehole. <br />Please recall that TR-61 provided for ventilation borehole V13-1 S-01. We have determined the need for a <br />small diameter utility borehole to provide for instrumentation monitoring/communication cable to the <br />underground operations. We plan to drill a 6 3/4" borehole then cement into place a 4'/2" steel casing. The <br />depth of the borehole is estimated to be 447' in depth. We estimate the borehole will be located about 10 <br />- 15' east from the yet to be completed VB-1 S-0 1 borehole. As we are using the same drill pad, no <br />additional surface disturbance will be required for this borehole. <br />A modified excerpt of PAP Map 2.05-M 1, Sheet 6 of 6 is attached for the Division's information. We <br />will forward a final map in the near future. We have also included a revised Exhibit 2.04-E3, Item 9 - <br />Methane Drainage Well Information. <br />Please contact me at 970-929-5806 if I can provide any additional information or if you have any <br />questions. <br />Sincerely, <br />J es A.
