Brown" <Sandy.Brown @state.co.us> Spencer: Fri, Jun 13, 2014 at 2:43 PM During our inspection of the Carbon Junction Mine on June 4, 2014, most of our attention was focused on what is termed the "Upper Carbon Junction Channel ", which extends upstream of the rip - rapped Permanent Diversion Channel. 1 provide the following, on the understanding that your inquiry is related to the Upper Carbon Junction Channel work that was completed in 2013. When the Division issued NOV CV -2013 -005 to Oakridge Energy, Inc. ( Oakridge) on 23 May 2013, four separate Abatement Steps were spelled out in the NOV. With Step #2, we required that Oakridge submit designs and plans for: reestablishment of the Upper Carbon Junction Channel, including the un -named tributary, and for reclamation and stabilization of the temporary diversion and gully erosion. Steps #3 and #4 required that the work be accomplished in accordance with the plans developed under Step #2. The application for TR -17 was submitted on 28 Aug and deemed Complete on 04 Sep 2013, which resulted in Abatement of Step #2 (and #1, which is not discussed herein). Adequacy issues were addressed to the Division's satisfaction, and we issued our proposed decision to approve TR -17 on 29 Oct. No comments were received, and we formally Issued the revision on 12 Nov, at which point Oakridge's contractor commenced with the repair and reconstruction work. Construction was completed on 18 Nov in accordance with the TR -17 approved design; Steps #3 and #4 were abated on that date. The new design approved with TR -17 replaced all previous designs for the Upper Carbon Junction Channel (everything upstream of the rip - rapped Permanent Diversion channel). Goff Engineering and Surveying developed the TR -17 plans, and these were incorporated as new "Exhibit 5 -12 ". Given Goff's unfamiliarity with our Rules and other details of the Carbon Junction permit, changes made under TR -17 were limited to the insertion of Exhibit 5 -12. [ Oakridge's regular permitting consultant was struggling with serious health issues during most of 2013, and was unable to participate in the TR -17 process.] We are currently working with Oakridge's regular consultant to update /revise the remainder of the permit to remove any information which is contradictory to the material approved with TR -17. A Permit Revision application will be submitted by Oakridge later this year, and will address reconciliation of the channel design as well as revising the post - mining land use. If you wish to review the design details (text and maps) approved under TR -17, they may be found in our Laserfiche system, as follows: Permit No.: C1992080 IBM Index Class Name: Permit File Doc Date: 10/29/2013 Please let me know if you have any additional questions regarding our inspection of the Carbon Junction Mine. https: / /niaii.g oog le.comlm@i I /idol ?ui =2 &i k=91 a975f658 &)i ev,--pt &search= inbox&msg = 14696f8993ao8fce&si m1= 14696f8993aoBfce 1/2
