Summary of Preliminary Adequacy Review for TR-111 <br />Mine: West Elk Date review completed: 11/15/07 /L <br />Permit No.: C-80-007 DMG reviewer: Tom Kaldenbach <br /> Require- <br /> ments <br />Requirements complied Comment <br /> with ? (yes I <br /> no <br /> Work proposed by TR-111 will be within the area added to the permit area <br /> in previously approved PR-10. <br />Right of entry <br />NO The USFS issued a decision on November 8, 2007 that approves the work <br />(2.03.6(1)) proposed in TR-111, but the approval will not be final until expiration of an <br /> appeal period. (The decision was an approval of the FEIS titled"Deer Creek <br /> Shaft and E Seam Methane Drainage Wells Project".) Right-of-entry will be <br /> adequate only when the USES decision becomes final. <br />Cultural resources Cultural resources surveys appear adequate based on their description in <br />(2.04.4) Yes the submittal and in the above-referenced FEIS. DRMS has not received a <br /> comment letter from the SHPO. <br />Fish/wildlife Fish and wildlife information appear adequate based on information in the <br />information (2.04.10, <br />Yes submittal (Habitat and Baseline Studies, July 2007) and in the above- <br />2.04.11, 2.05.6(2) referenced FEIS. DRMS has not received a comment letter from the CDOW <br />and 4.18) or USFW. <br />Maps and plans <br />Maps <br />Yes <br />The submittal includes a wellbore diagram and a PE-certified map. <br />Light-use roads The exact locations of the approximately 1.5 miles of new roads will be <br />(4.03.3) Yes identified in a subsequent MR or TR. The TR-111 submittal provides a <br /> conceptual design that is adequate for the purpose of this TR. <br />Topsoil (4.06) and <br />topsoil markers Yes Page 8 of the submittal provides for topsoil stockpiling and marking. <br />(4.02.7) <br />Water quality Runoff from pads and roads can be expected to be alkaline with quality <br />protection (4.05.2) Yes similar to pre-disturbance conditions. The runoff will be too alkaline to form <br /> leachates or to mobilize metals. <br /> The mudpit for each drill pad will not be part of the sediment control <br /> system for the pad. Each mudpit will be an impoundment (1.04(64)) that <br /> will not have a spillway (4.05.9(2)(e) and will be located where failure <br /> would not be expected to cause loss of life or serious property damage <br /> (4.05.9(2)(e). The submittal includes a safety factor demonstration for the <br />Impoundments <br />NO mudpits (Galena run using Simplified Bishop's method with a single circular <br />(4.05.9) failure surface), but the submittal contains only a profile and does not <br /> include a printout of input and output data. These data need to be submitted <br /> in order for the demonstration to be adequate. A PE-certified mudpit design <br /> is in the submittal showing the mudpits are sized to hold all of the cuttings <br /> from the boreholes and expected surface runoff, with 1 ft. of freeboard, from <br /> a 25-yr., 24-hr. storm (4.05.9(2)(c)).
