Trapper Response to Comment 4: The Trapper permit addresses impacts to neighboring wells,water rights and the hydrologic balance in several sections. Specifically,analysis was included in the PR-1 lapplication through updates to sections 2.7.4.1,2.7.5.2d, should be 2.7.5.3d 4.8.2.2,and 4.8.5.2. The noted monitoring wells, (Peabody Energy,Williams Fork Mines;TR-4 and 84-01)located within the proposed permit expansion area have been noted on Trappers long range planning maps and attached revised M13A(sheet 1). As these wells are not registered with DWR as water wells or monitor wells(Rule 2.04.7(1)(b)),they were not located or added to the M31 Water Rights map. As these wells are monitoring sandstone aquifers several hundred feet below our deepest coal seams,no impacts are expected to those aquifers through mining at Trapper. When I West-Pit is developed,our preferred development plan at this time is to avoid adjacent archeological sites and these monitoring wells entirely with pit disturbance and highwall mining at the western extent of the pit. If Trapper must disturb these structures,they will be replaced by Trapper Mining Inc.for Peabody Energy. Trappers' response adequately addresses DRMS's concerns regarding the Peabody Energy Wells. The Lux residence potable well is actually located on their private property,north of the proposed permit expansion boundary. The location given is what is on record for their water rights filing with DWR. While Trapper will not directly disturb this well with surface impacts,it is possible the highwall mining of the F seam in I West-Pit may affect the water quality of this well,however,impacts may be negligible. If impacts are noted,Trapper has committed to replace any vested water right or source if harmed. DRMS 28 February 2023 As per Rule 2.05.6(3), (Protection of Hydrologic Balance), the protection of surface and ground water must be ensured and the rights of present users protected and to provide alternative water sources as per Rules 2.04.7(3), and 4.05.15. Trapper Mine Inc. has adequately addressed the Lux well water right replacement. DRMS also notes that no major undisturbed drainage exists within the permit boundary however, no discussion was included regarding Rule 2.04.7(3), regarding alternative water supply in the expansion area. DRMS 28 February 2023 Trapper Response to Comment: Alternative water supplies will be handled in the expansion area in the same fashion as any other area of the permit area,either with well replacement or surface water rights most likely from the Yampa River. The above rule is adequately addressed. 5. There are fewer existing sediment ponds than PR 7 table,please discuss and call out sediment ponds and their permitting action that may have been reclaimed since PR 7. Trapper Response to Comment 5: Though technically not a sediment pond,the Industrial Waste Pond(IWP),was included as such in PR-7. To maintain consistency,the IWP was added back into the Table 4.8-1 calculation. Thus, back to 41 sediment ponds. Trappers' response adequately addresses the above cited rule. 6. Existing stock ponds have decreased from 68 in PR 7 to 55 in PR I],please discuss and call out stock ponds and their permitting action that may have been reclaimed since PR 7. Trapper Response to Comment 6: Over the years more stock ponds have been reclaimed,either deliberately with mine machinery or passively as they filled with sediment over time,than new stock ponds being built.Most of the 4 Trapper Mine PR I ADQ No 2 2023 February
