MR236 adequacy <br />2 <br />3/4/2009 <br />B. Revised page 2.05-45.6g has eliminated text previously approved with MR09-235 (rev. <br />2/26/09) discussing the "18-Left Mine Ventilation Shaft Installation" geotechnical <br />boreholes. Please assure that this text is retained in the revised pages. <br />C. Revised page 2.05-45.7 has eliminated text added in MR09-234 discussing the temporary <br />and permanent Shaft Heaters. However, TCC has reincorporated text approved with TR61 <br />back onto this page. Please assure that previously approved text is not lost. The submitted <br />revised page 2.05-45.6g also still includes 3 paragraphs discussing the "No. 7 North Escape <br />Shaft" that are repeated on MR09-236 revised page 2.05-45.8. <br />D. D) Revised page 2.05-45.7 (2/23/2009) reinstates previously approved text from TR61, <br />however, it doesn't flow from the text of the preceding page (2.05-45.6g). Please assure <br />that the revised text fits into previously approved text and that previously approved <br />information is not lost. <br />The Division agrees with TCC's reclamation cost estimate for this revision. The Division determined <br />MR236 to be complete on March 3, 2009. Please provide responses to the identified adequacy concerns <br />prior to March 13, 2009, to meet regulatory time frames. <br />Please call me if you have any questions regarding this review. <br />Sincerely, <br />anet H. <br />iviro ntal Protection Specialist II <br />03) 866J3567 ext. 8107 <br />Enclosures: Previously approved pages.
