Susan Burgmaier 07- Jan -2014 <br />C- 1996 -083 TR -84 PAR Page 2 of 5 <br />TR-49 (Jun- 2009): With this revision, designs for a Haul Road were approved which facilitated <br />trucking of coal mine waste from the mine's preparation plant, across SH 1338, to CMWDA #3. <br />This represented a change from BRL's original concept, that of using a conveyor to transport the <br />material to the disposal area. No changes to the configuration of the refuse pile were requested <br />or approved under TR -49. <br />MR -139 (Sep - 2013): This revision provided details regarding phasing of coal mine waste <br />disposal at CMWDA #3. The Construction section of the Volume XI text was modified to state <br />that placement of refuse would start at the western edge of the pile and progress eastward. <br />Salvage of coverfill and topsoil materials from the pile's footprint would continue. Concurrent <br />to MR -139, the operator was seeking Division approval of TR -80, construction of an underdrain. <br />The operator committed to limiting CMW placement operations to areas outside a buffer zone <br />until construction of the underdrain was completed. <br />TR -80 (Sep - 2013): During excavation of coverfill material from the footprint of CMWDA ##3, <br />the operator identified a seep which appeared to be related to the Fire Mountain Canal. The <br />Canal runs roughly parallel to SH 133B, between the highway and the refuse pile. Construction <br />of an underdrain across the full width (from north to south) of CMWDA #3, from the seep to the <br />collection ditch, was approved with this revision, under 4.10.3(5). No changes to the final <br />configuration of the refuse pile were requested or approved. <br />MR -141 (Oct - 2023): Due to the high moisture content of material produced by the preparation <br />plant, the Detailed Design section (pages 4a and 4b) of Volume XI text was revised to designate <br />a drying area for the Coal Mine Waste. <br />MR -144 (Nov- 2013): Page 4a of the Volume XI Text was further revised to include a <br />description of temporary pipes that are used to convey water away from the coal mine waste as it <br />drains from the material recently dumped in the drying area. <br />TR -84 Adequacy Review <br />For this review, I was provided with the following items by Stover's office: <br />Volume I: <br />All pages listed in cover letter <br />Volume 11: <br />All maps listed in cover letter <br />Volume III: <br />All Exhibit 8 pages listed in cover letter <br />Volume IX: <br />All Appendix B pages listed in cover Ietter <br />Volume XI: <br />Pages 1 -4 and 5 -11; Buckhorn Geotech Stability Analysis, and Figure I <br />Volume XI: <br />The primary purpose of my review has been to evaluate the proposed reconfiguration of <br />CMWDA #3. With TR -45, side slopes of 3h:ly were approved, for a pile height of 65 feet. TR- <br />84 proposes steepening the slopes to 2.5h:1 v, and increasing the height to 120 feet. In support of <br />
