Cattany <br />DATE: June 15, 2008 Division Director <br />TO: Jim Stark Natural Resource Trustee <br />FROM: Dan Mathews <br />RE: Colowyo TR-72 (Reclamation Plan and Phase III Bond Release Criteria) <br />Permit C-81-019 <br />Pursuant to your request, I have reviewed Colowyo's May 27, 2008 submittal that was in response to <br />our Preliminary Adequacy Review (PAR) letter of April 29, 2008. <br />My specific review comments are set forth below. For each item, I briefly summarize our original <br />concern and the operator's response, and then provide my assessment. <br />Backfilling and Grading [2.05.4(2)(c) and 4.141 <br />The Division requested additional detail regarding the scale and spacing of features <br />referenced in the text to create/enhance small scale topographic variation. The operator <br />declined to provide additional detail. The Division will not press further, but will monitor <br />final grading operations to ensure that the operator is following through with their stated <br />intent to achieve appropriate topographic variation, including "site specific opportunities for <br />development of convex and concave surfaces to encourage snow entrapment". Item <br />Resolved. <br />Topsoil [(2.05.(2)(d) and 4.061 <br />2. The Division requested that the operator provide an updated Table 2.05-1 to reflect current <br />status of topsoil volumes for the original permit area, and to provide a new table or <br />supplement to Table 2.05-1 to reflect current projections for the South Taylor Area. The <br />Division also requested that narrative of Section 2.05.4(2)(d) in Volume 12, be updated as <br />warranted to correspond to current projections. The operator declined the request, explaining <br />that the table is updated in the annual reclamation report. <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
