The inspection was conducted, and the report and photos prepared by me, Robin Reilley of the DRMS. Graham Roberts Trapper Mine representative was present throughout the inspection as was Jim Stark of the Office of Surface Mining. No hydrologic or air quality issues were detected at the time of inspection. Skies were partly cloudy, and there was an intermittent breeze. Temperatures ranged between 45 and 70 degrees Fahrenheit. PERMITTING ACTIONS in PROGRESS: SL 25 PR12 INSPECTION GENERAL MINE PLAN COMPLIANCE: Roads were being watered and coal and overburden were being loaded and hauled. J Pit West: Mining to the east area of the pit is scheduled for late this year (2024). Mining should be completed early next year (2025) so reclamation could begin. The Queen Ann dragline was staged in J Pit West. J Pit mining will resume in the G seam once the dragline is repaired. There was some standing water on a portion of the south pit wall. D Pit: Topsoil depths were measured in the D Pit. Topsoil was being spread in the D Pit area where it had not been spread in 2023. D Pit discing and seeding are scheduled for later in the week. The temporary seed mixture comprised of triticale although dormant showed good germination and cover. Erosional features existing at the apex of the D Pit constructed drainage as well as areas between check dams and along slopes had been repaired. N Pit: Coal extraction was idle at the time of inspection. A coal pile exists mid pit. This pile was being added to for eventual loading and hauling from the west end of the pit. The N Pit west end will be backfilled providing access to the next level coal. All the adits in the N Pit are backfilled. An interburden blast was set up on east end of the pit.
