Box 187 Craig, Colorado 81626 RE: Trapper Mine; C- 1981 -010; Technical Revision Bo. 113; Annual Reclamation and Hydrology Report, Appendix W, Adequacy Review No. 1 Dear Mr. Roberts, The Colorado Division of Reclamation Mining and Safety (Division) has completed its preliminary review of TR113 consisting of the Annual Reclamation and Hydrology Report. There are several items that will need to be addressed prior to the approval of TR113. Please address the following items: Enclosed is a letter from the Colorado Division of Water Resources (DWR) dated April 21, 2014. Several items were noted in the letter in regards to the compliance with the requirement of the State Engineers Office. The first item is in regards to the stock water ponds present at the site. The second item is in regards to the proper permitting required for the dewatering operations. The third item is in regards to the types of well permits that need to be obtained for the monitoring wells and exploration boreholes at the site. During the review of the 2010 Annual Reclamation Report, the DWR submitted similar comments to the Division. On July 26, 2011 Trapper responded to the DWR's comments. It appears items in regards to the stock water ponds and de- watering wells were addressed at that time. In regards to the well permitting item, Trappers 2011 response letter indicates the monitoring wells were constructed per the permit under the direction and approval of the Division. On August 12, 2011 the DWR responded to Trappers letter and indicated that all wells operating within DRMS permitted sites that are being used with the intent of accessing ground water, including wells used for the monitoring and observation of water quality /levels, are still subject to the State Engineer's Office well permitting requirements. Enclosed is the DWR's August, 2011 response letter. Please provide a response to the DWR concerns. Trapper mine will need to work with the DWR to comply with their permitting requirements. Once this is completed Trapper will need to update section 1.2.2 of the OF cOG0 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http: / /mining.state.co.us I John W.
