Colowyo Coal Company 573 State Highway 13 �. Meeker, CO 81641 Q Mr. James R. Stark Environmental Protection Specialist �+ Colorado Division of Reclamation, Mining and Safety Q Department of Natural Resources 1313 Sherman Street, Room 215 Denver, CO 80203 December 21, 2010 DEC 2 72010 RE: Response for Preliminary Adequacy on Application for Phase I and II Bond Release on 1996 -2003 Reclaimed Areas, Colowyo Coal Company L.P. Permit No. C- 1981 -019 Dear Mr. Stark, Colowyo would like to thank you for your review of the Phase I and II bond release applications submitted to the Division earlier this year. After reviewing all of the preliminary adequacy questions presented in the letter dated November 23, 2010, Colowyo has the following comments and responses: Phase II Revegetation Monitoring Data from 2006 and 2007 vegetation sampling for Partial Phase II Bond Release SL -04 includes data from reclamation blocks that are not included in the application. These reclamation blocks include FA001, FA002, FA003, S16002, S16005, S16009, S16011, S16012, S16013, S16015, and S16016. In orderfor the Division to consider the vegetation sampling data from 2006 and 2007, data collected from the above referenced reclamation blocks will need to be removed from the data set. Data collected from transects 3, 30, 31, 32, 34 and 35 from the 2006 sampling year fell within reclamation blocks not included in the Phase II Bond Release application. Data collected from transects 4, 33, 34, 35, 36, 38 and 39 from the 2007 sampling year fell within reclamation blocks not included in the Phase II Bond Release application. Please either update the 2006 and 2007 vegetation monitoring reports to eliminate data from the reclamation blocks not included in the Partial Phase 11 Bond Release SL -04 application or please remove the 2006 and 2007 vegetation monitoring reports from the SL -04 application. If the data for the above referenced parcels is removed from the 2006 and 2007 vegetation monitoring reports, all of the cover and sample adequacy calculations will need to be redone. Please note that reclamation blocks S16010 and S16014 were only sampled in 2006 and 2007. The elimination of the 2006 and 2007 vegetation monitoring reports from the SL- 04 application will also require the removal of these reclamation blocks from the application.
