INTEROFFICE MEMORANDUM <br />TO: RYRON W.\L :R / <br />FROM: JANI~: I' RINNS <br />SUBJECT: EDNd LINE, C-1 -001, Sr\G ?RRUSH/SNOWRERR 2EPLe\CGMEN"I' RI?.PEIiENCL' ARfr\ <br />DATE: 7/28/2 <br />CC: Dr\N 1-IERNANDE%, Sr\NDY RROWN <br />I have reviewed Pittsburg cec Midway Coal Company's (PScM) proposal fora replacement <br />Sagebrush/Snowbetry reference area. The proposal was not submitted as a revision but more of a <br />vegetation sampling plan to document how they will verify the similarity of a new <br />sagebrush/snowberxy reference area to replace the reference axe that was damaged this summer. <br />The proposal provides a description of how comparisons of baseline vegetation sampling data, <br />interim vegetation sampling data ,and bond release sampling data collected in 2005 and 2006 will <br />compare to the replacement reference area. The plan appears logical, and I do not have any <br />questions. The opexatox has anticipated an approach to correlate production and cover trends to <br />develop an adjustment factor in case the historic data and the 2006 data differ significantly. <br />Several inconsistencies were noted in the proposal, which appear to be typographical errors: <br />1. Page 3 ox 5: Equivalency analysis. W '99: O-'99 indicates that 1997 Interim data fox Whole Original <br />Reference Area would be used. This is the first reference to a 1997 data set, and it would not be <br />logical to compare the whole data set to a portion of the set from different sampling years. I suspect <br />that this should read 1999 Interim data. Please have the operator review this page and confirm if <br />this, indeed, is a typo. <br />2. Page 3 or 5: Equivalency analysis E-'99: O-'99 indicates that 1997 Interim data for Whole Original <br />Reference Area would be used. This is the fast reference to a 1997 data set, and it would not be <br />logical to compare the whole data set to a portion of the set from different sampling years. I suspect <br />that this should read 1999 Interim data. Please have the operator review this page and confirm if <br />this, indeed, is a typo. <br />3. Page 3 or 5: Equivalency analysis: W-O5: O-OS states that 2005 Bond release data for the East <br />portion of the original reference area will be used for comparison. I think they meant to say the <br />West portion of the original reference area. Please have the operator review this page and confirm if <br />this, indeed, is a typo. <br />4. Page 3 or 5: Equivalency analysis: E 'O5: O `OS states that 2005 Bond release data for the West <br />portion of the original reference area will be used for comparison. I think they meant to say the <br />West portion of the original reference area. Please have the opexatox review this page and confirm if <br />this, indeed, is a typo. <br />
