The changes proposed directly affect the coal resource and <br />the resource recovery and protection plan (R2P2). The changes made do <br />constitute a significant change of the lease R2P2. <br />The modification results in higher recovery and improves the maximum <br />economic, recovery on the lease. Tne information supplied is complete and <br />satisfactory. The slight change in recoverable reserves is not considered <br />large enough to revise the lease recoverable reserves estimate at this <br />time. P.ccordingly, this mine plan/R2P2 revision is approved. <br />The information submitted with your letter dated November 10, 1988, and <br />the additional map supplied in December is sufficient to update the P.2P2 <br />and should be supplied to OSM and C^1LRD to update their copies of the mine <br />plan if you have not already done so. <br />If you have an;' questions concerning this approval, please call Jerry <br />Strahan at (303) 824-8261. <br />Sincerely, <br />District Pianager 'j <br />'`+ ~. <br />CNQ,RD ~'- _ _ _1, <br />_ ~ C` „+z, <br />// " <br />~/p ( ~-- <br />rte,...
