Canany <br />Division Director <br />RE: Seneca II-W PR-5 Adequacy Response Review Natural Resource Trus[ee <br />Seneca Coal Company <br />Permit No. C-1982-057 <br />Sandy, <br />I need to request the review assistance of yourself, Mike Boulay, Jim Stark, and Byron <br />Walker, in regard to the above referenced adequacy response review. Seneca Coal <br />Company (SCC) submitted respo9nses to our adequacy letters of July 11, 2005 and <br />August 25, 2005, under cover letter dated January 31, 2006. I would like to receive <br />review memos by March 9, 2006. <br />From the individuals involved in the review I would like to request the following: <br />Mike: <br />Please review the responses to Items 10 through I7, and associated revisions to postmine <br />channel designs, SEDCAD designs, drainage and sediment control plans, and stock pond <br />designs. <br />Byron: <br />Please review the responses to Item 6 and associated amendments to Tab 20 text, new <br />Attachment 20-2A Pit Backfil] Stability Report, and revised Map Exhibit 20-2 and <br />associated cross-sections relevant to slope stability. <br />Jim: <br />This submittal does not explicitly respond to the cost estimate, but Roy Karo indicated <br />that he thought the cost estimate issues of dispute were now in our court. Given that the <br />disturbance acreages have been revised per Item 1, and that revised postmine channel <br />designs have been provided, the cost estimate probably needs to be adjusted to <br />incorporate these changes. Please review SCC's responses to Item 1, Item 4, Item 16, <br />STATE OF COLORADO <br />Office of Office of Colorado <br />Mined Land Reclamation Active and Inactive Mines Geological Survey <br />
