BANTA, Director <br />DATE: June 6, 1989 <br />T0: File <br />FROM:~atthew Hayes plu,d-QN ~ <br />RE: Adequacy Review of TR 55, Mt. Gunnison Mine No. 1, <br />File No. C-80-007 <br />An adequacy review of the Mt. Gunnison B-Seam Technical Revision was completed <br />regarding discrepancies between the revised application pages and those <br />presently approved pages. I also carried out a general review of whether all <br />issues were addressed that needed to be. Cathy Begej reviewed hydrology <br />issues while Jim Pendleton reviewed subsidence/stability issues. <br />A. The following issues represent simple editing mistakes. Please <br />submit revised pages that correct these mistakes. <br />1. Revised page 2-499 does not have deltas ("4 ") inserted at <br />correct locations in Equations 1 and 2 or in the narrative <br />below. <br />2. The top paragraph of revised page 2-542 reads "Four Springs, <br />E-20, G-31, and WCC-23 were identified. Comparison wi th <br />the old permit indicates it should read, "Four Springs, G-6, <br />G-12, G-13 and G-15 were identified as being located witlTTin <br />Tb~fe~a~ove le Fpm an ree Grp logs, ~2~~- ,and <br />WC~-mere i3entifle . <br />3. The phrase, accidents damaging the mine, the. ." has <br />been mistakenly deleted from the bottom of page 3-11. <br />4. The phrase, permanent cover for erosion control.", has <br />been mistakenly deleted from the top of page 3-14. <br />5. On page 3-53, in the bottom paragraph, "silo" should be <br />"silos". Have other references to a single silo been updated <br />to reflect the fact that two exist? <br />B. In revising permit application pages, several deletions were made <br />by West Elk Coal Company (WECC) which require clarification. WECC <br />should address whether these deletions are part of a previous <br />revision and why they have been deleted. <br />215 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel.
