Sherman <br />Executive Director <br />Ronald UV. Cottony <br />Division Director <br />Natur?I Resource Trustee <br />The Division has reviewed the shove referenced technical revision application, and we are <br />largely in concurrence with the study recommendations, fur understanding based on your <br />email of August 'i 1, 20a9, is that the scope of the Panel ?? ? study will be expanded to <br />incorporate the additional slide features to the east of Pond g? A, and that the final remediation <br />plan gill encompass the entire slide complex in the vicinity of Ponds 4? ?, 0? GA, and the nearby <br />shrub establishment area. fur further understanding is that the Pond 0? ??0? A area slide <br />remediation plan technics[ revision application will be submitted in early ?g? 0 presumably by <br />the end of the first quarter of ?0? g?, to allow far irnplernentation during the X01 g field season. <br />vie make the following two requests, in order to eliminate confusion with regard to the <br />Attachrnentdesignationslisted on the amended Tab ?g table of contents, and to incorporate <br />SCC commitments regarding the study plan and forthcoming remedial plan timeline into the <br />permit. <br />? . The amended Tab 2g table of contents page ii lists Attachment ?0-D as "Shrub Plot <br />Slide Remediatian Plan" and Attachr?ent ?0-E a "Panel ??fi Slide Remediatian Plans", <br />The inserkion instructions are to insert the new material as Attachment ??yD, which is <br />confusing, because the focus of the study plan submitted is an the Panel ?? 6 slide area <br />rather than the shrub plat slide area. <br />Based an email correspondence, best approach might be to have a single Attachment <br />?2Q-D}, titled "Pond o1 GI01 ?A Area Slide Stabilization Plan", or something similar. <br />Attachment ?g-E would then be unnecessary. Please address the discrepancy <br />between the TO page and the insertion instructions and revise a necessary. <br />Office of Office of <br />Mined hand Reclarnat[on Denver • Grand Junction ?
