Bowie intends to drill five methane de- <br />gas holes and four exploration holes, all within the currently approved permit area. There would <br />also be the associated surface disturbance of new and upgraded light use roads and drill pads. <br />Jim, if you could review the bond estimate, I would appreciate it. The submittal includes Bowie's <br />bond estimate. <br />Mike, I am asking you to look at the proposal to see if there are any adequacy issues with the <br />drilling and sealing of these holes. <br />The permit application contains information on reclamation procedures for light use roads and <br />drill pads. The discussion begins on page 2.05-47 of Volume I. A discussion of well sealing <br />begins on page 2.05-57 of Volume I of the permit application. A typical well completion <br />diagram for a methane de-gas hole can be found in Exhibit 3 of Volume 3A. <br />Attached is a complete copy of the TR. If you need any additional information, please let me <br />know. The revision was called complete on May 30, 2002. The Division's adequacy review letter <br />is due on June 29, 2002. Thanks for your assistance! <br />Attachments <br />cc: Sandy Brown (without attachments) <br />c:1ms97\bowie2\tr23memo 1 <br />
