GCC GCC Energy, LLC Telephone. 970.385.4528 6473 County Road 120 Energy "Safety as a Value" Facsimile- 970 385 4638 Hesperus, CO 81326 December 28, 2015 State of Colorado Division of Reclamation, Mining & Safety 1313 Sherman St., Room 215 Denver, CO 80203 Attn: Robin Reilley, Environmental Protection Specialist Re: GCC Energy, LLC King II Mine CDRMS Permit # C-81-035 Technical Revision #20 - Adequacy Review #3 Response Dear Ms. Reilley: This submittal is in response to your letter of October, 2015, "King Coal Mine (C-1981-035) TR -20 - Adequacy Review #3" Response". The original purpose of this technical revision was to allow the use of coal mine waste from the King II mine to be placed along the west pre-SMRCA high -wall cut at the King II mine. This material would be placed in such a way as to approximate pre -disturbance profiles of the west high -wall and help to lessen the visual impact of the site. As mentioned, the site is pre -law, and GCC Energy is under no obligation to construct this structure. On June 9, 2015, GCC Energy received a letter from your office requesting additional sampling and analysis of the existing refuse pile at the King I mine as well as additional roof, coal and floor sampling and analysis of areas within and adjacent to the King II mine. These concerns were originally addressed in our TR -20 "Adequacy Review 2A (Supplemental) Response", submitted June 30, 2015. That response has been reviewed by the Division and additional comments were received from the Division by GCC Energy as TR -20, Adequacy Review #3. Those comments are addressed in this submittal. The Division's adequacy comments from the October, 2015 letter that were noted as "Resolved" are not addressed in this submittal. Comments which were not resolved are repeated below in italics as listed in your letter. Responses by GCC Energy are shown in bold text.
