Related to questions #4, how will drainage be handled on the large mountaintop area? <br />The large expansive azeas of the proposed post-mining topography (PMT) would appeaz <br />to require some drainage network or drainage plan to direct flows to downdrains and <br />other ditches. The permanent road would also seem to modify drainage slightly in the <br />mountaintop azea. Please address this important issue. <br />6. The long steep slope proposed across the center of the mountaintop does not seem to <br />resemble the pre-mining topography of that azea. The Division would be more in favor <br />of a continued reconstruction of the subdued ridgeline. Please consider a modification in <br />this area. <br />Permit text should be included with the revision discussing the Small Area Exemption <br />area for the office azea and the coal cleanout azea at the loadout. Sediment control <br />measures such as gravel, straw bales, and silt fence should be specifically identified and <br />the reclamation plan for these areas should be discussed in the pemut text. Since the <br />office area was a previously disturbed area from ranch and oil and gas activities, please <br />include scarification for this azea prior to seeding. <br />8. Map 2.05.3-3b, Jeff Canyon Haul Road shows a road profile and a plan view. However, <br />the plan view seems cut off and possibly duplicative with Map 2.05.3-3a. Please re- <br />evaluate the need for the two maps. Also, since the Jeff Canyon South Haul Road has <br />been removed from the plan, please remove reference to culverts for that road from map <br />2.05.3-3a. <br />This concludes the initial review of TR-08. Cost estimate questions will be forwarded under <br />separate cover. If you have questions or comments, please call me. <br />Sincer y, /- <br />Ken .
