COLORADO <br />_/ Division of Reclamation, <br />® Mining and Safety <br />Department of Natural Resources <br />Tom Bird <br />Manager of Coal Services <br />GCC Energy, LLC <br />6473 County Road 120 <br />Hesperus, CO 81326 <br />tbirdk cg c.com <br />August 28, 2020 <br />Re: King I & II Mine, C1981035, PR10 Preliminary Adequacy Review <br />Dear Mr. Bird: <br />The Division has reviewed GCC Energy's application for a permit revision, PR10. The PR10 <br />application was received electronically on June 24, 2020. The application was determined to be <br />complete on June 29, 2020. GCC Energy, LLC (GCC) provided additional materials on July 1, <br />2020, and August 8, 2020. The following comments are a result of review of the submitted <br />materials. <br />1. Please ensure the hydrology maps, specifically Map KII -004 and KII -012, accurately <br />show the extent of the proposed mine workings. <br />2. It appears East Alkali Gulch will be impacted by the mining proposed in PR -10, however <br />MW-7-EAA and MW-8-EAA, the two monitoring points for that drainage, are both <br />located down -gradient of proposed new mining. Please add an up -gradient monitoring <br />location or provide rational as to why one would not be needed. <br />3. Appendix 15 discusses the trenching of East Alkali Gulch to construct a low -cover <br />crossing, but the location of this is not provided on the hydrology maps. Please add the <br />location of this disturbance to the hydrology map in relation to its proximity to the DRMS <br />permit. It appears there will be surface disturbance associated with the trenching and <br />staging areas. Please specify if any of these disturbance areas fall within the DRMS <br />permit boundary. <br />4. It is not clear if there will be any subsidence monitoring. Or if there is a plan to monitor <br />while undermining drainages. Please provide additional information on the subsidence <br />monitoring plan. <br />5. King II Map -001, Permit and Adjacent Areas, uploaded 6/25/2020, (Map date 6/12/2020) <br />is incomplete.. It appears that only a portion of this map uploaded to the Division's <br />laserfiche file. Please resubmit the entire proposed permit area map. <br />.OF 'Co <br />y ' <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 https:/colorado.gov/drms I <br />Jared S.
