Dan Mathews -4- September 7, 2007 reclaimed. The monitoring plan described appears to be a relict that no longer applies (a similar plan for McClane Mine was terminated in 1983). As such, we would request that the Resource Monitoring Section be deleted from the Wildlife Plan. CAM: The `Resource Monitoring' section of the Wildlife plan on pages 4-56 through 4-58 of the application narrative has been deleted. k) The "Threatened and Endangered Species" section of the Wildlife Plan, on pages 4-51 through 4-52 of the application, should be revised to remove outdated text and incorporate the "Draft Biological Assessment - DMG Permit Renewals", prepared by Rare Earth Science, LLC, dated March 27, 2006. We would recommend that the report be summarized in the text, and included as an appendix to the permit application. The report was included as Table 4.3-9 of the McClane Canyon Mine permit application document. In addition, we would recommend that a copy of the June 16, 2006 Consultation Memo from Allen Pfister of USFWS to Carl Johnston of OSM be included as a permit appendix. This memo documents USFWS concurrence with OSM's Biological Assessment determinations, consistent with the conclusions of the Rare Earth Science report, and further documents USFWS determination that consultation has fulfilled applicable requirements of the "Recovery Implementation Program for Endangered Fish Species in the Upper Colorado River Basin". CAM: The Threatened and Endangered Species section of the Wildlife plan on pages 4-51 through 4-52 have been updated. The Biological Assessment Report conducted in March of 2006 has been included as Table 4.6-9. The June 16, 2006 Consultation Memo from Allen Pfister of USFWS to Carl Johnston has been included as Appendix L-iii. 4. During the reclamation project currently underway at the mine, site conditions have warranted a number of modifications to the approved plan, including incorporation of additional riprapped permanent drainage channels along the upper road reclamation corridor, re-location of a diversion ditch above the remnant cover soil stockpile at the waste disposal site to better fit the site topography, minor alteration of permanent drainage channel profiles and lengths due to field conditions and safety considerations, and possibly other minor deviations from original specifications. In order to eliminate any future questions regarding deviations from the approved plan, and to ensure that the reclamation contours and ditch and channel specifications comply with applicable regulatory criteria, we have the following request. Please submit to the Division a complete technical revision application with certified "as-built" reclamation contours, cross sections, and ditch/channel specifications, addressing any modifications to the approved plan (such as the additional riprapped channels, and any changes in channel slope, length, or other design parameters necessitated by field conditions).
