Walther <br />FROM: Joe Dudash ~ Executive Director <br />Ronald W. Cottony <br />RE: Geotechnical pleteness Reviews, PR-7, B-Seam Portals, PR-8, B-Seam Division Director <br />Mine Plan, Bowie No. 2 Mine, Permit No. C-96-083, Bowie Resources LTD. <br />I am requesting your assistance in the geotechnical completeness reviews for PR-7 and PR-8, <br />Bowie Resources Limited (BRL) wants to open up the B-seam for mining and will need to <br />construct a new facilities bench, material storage bench, haul road and associated facilities <br />structures. The facilities construction is covered in PR-7 while the mine plan is covered in PR-8. <br />The construction of the facilities complex to support the mining of the B-seam was submitted in <br />PR-7. Please determine whether or not BRL has geotechnical completeness in PR-7. BRL has not <br />included any geotechnical designs that are specific to the cut and fill operations proposed in PR- <br />07. BRL's consultant has stated that the construction pazameters used in PR-7 are consistent with <br />what has been approved in the original permit application. BRL is hoping chat this will suffice. I <br />have already given a complete copy of PR-7 to you. I have also given to you a copy of the Bowie <br />No. 2 permit application Volume VII, Geotechnical Studies, and the geotechnical correspondence <br />for the original permit application. Please determine if PR-7 can be called complete with what has <br />been submitted. <br />The B-seam mine plan was submitted in PR-8, a copy of which I have already given to you. <br />Please determine geotechnical completeness for PR-08. The submittal contains a mine plan for <br />the next five years. Further additions to the mine plan may be forthcoming, but not in PR-8. <br />Please remember that the B-seam is under the mined D-seam, so this may affect the subsidence <br />predictions. The PR-8 submittal contains maps showing the D-seam mine plan, the proposed B- <br />seam mine plan and the predicted subsidence. <br />PR-7 and PR-8 were received on February 28, 2003. Completeness determination is due March <br />1 Q, 2003. BRL is meeting with the Division this Thursday to discuss PR-7 and PR-8. It would be <br />nice if we can tell BRL the completeness status of PR-7, first, and PR-8, second, on Thursday. <br />However, I know you have a lot to do this week. I will send a separate memo for the adequacy <br />review request for PR-7 and PR-8 later. If you need anything else, please let me know, Thanks for <br />your help! <br />cc: Sandy Brown <br />Dan Hernandez <br />c:/word/bowie2/pr7compmemo 1 <br />
