<br />y.-~ <br />25. Map E-3214 also shows ditches and berms which divert flow ou[ of the Elk Creek channel. <br />All ditches and berms must be removed once the disturbed areas no longer contribute sediment <br />in excess of pre-mine levels or that of adjacent undisturbed lands. OCM should clazify that <br />all berms and ditches will be removed. <br />26. It appears, based on a review of Map E8-3286, that the proposed West Valley Fill will be <br />downstream of the downstream monitoring site on the North Fork. Please submit a plan for <br />a new downstream monitoring site. <br />2.05.4 Reclamation Plan <br />27. The application narrative indicates the canyon walls surrounding the northernmost coal <br />stockpile will be stripped to accommodate the pile. Will there be any additional earthwork <br />(cut/fill) at this azea? <br />28. Map E-3212 indicates a very large area will be disturbed and stripped of topsoil, which <br />appears to greatly exceed that which is necessary to construct the proposed structures. Please <br />either reduce the area to be stripped, or explain why the additional disturbance is necessary. <br />29. Map E-3213 shows that the conveyor between the B Seam Portal and the Elk Creek facilities <br />will be removed. Is this correct? <br />30. Please provide a new or revised description of all mine facilities, both proposed and existing, <br />which includes the location, composition, and dimensions. Please include in the dimensions <br />the width, length, height, thickness, distance below grade, diameter, azea, and/or circumference <br />as applicable. <br />31. Please provide volumes for all required earthwork to reclaim the site, and include a material <br />balance for construction and reclamation. Please indicate whether the volumes provided <br />include a material swell factor, and what factor, if any, has been applied. <br />32. Please provide a reclamation plan for the existing cemetery road which will be abandoned with <br />the construction of the new haul road. <br />33. Page 2.05-24 states that all foundations will be removed to 1' below grade. Foundations need <br />to be broken up and removed at least 4' below grade as to not interfere with rooting. Please <br />revise the text and reclamation plan accordingly. <br />Unrelated to my review, but things 1 noticed were: <br />- OCM did not include Pond C in the consumptive use estimates on pp 2.04-536 and <br />-53c. <br />- DOW wants OCM to regrade the West Valley Fill to approximate original contour, <br />and [o rehabilitate the drainage. We might want to make sure they're aware this is <br />a fll, and that AOC will not be achieved. <br />- Some of the maps have not been certifred (E-3211, -3213, and -3214; S-017A, -098, <br />-100; the 95255- series). <br />Should you or the operator have questions or need additional information, let me know. <br />m:\coallwjc\tr29.slb (in WordPerfect 6.1 format) <br />SLB\050597B <br />Bill Carter 4 May 6, 1997 <br />
