affected lands after reclamation. Please provide a revised Figure F-1 map which shows a closer view of the affected lands. 7) Please include the following information on Figure F-1: a) The approximate final slope gradients for disturbed areas (e.g., waste rock piles, valley disturbances, mesa disturbances, Black Forest backfill area). The slope gradients should be provided in this format"3H:1 V"or"2H:1 V—3H:1 V"or"2H:1 V or flatter". b) The location of all mine openings located within the affected land boundary and a brief description of how they will be reclaimed. For example, you might add"Steve Adit—locked gate"or"Black Forest Entrance—backfilled". c) Show all structures expected to remain for reclamation. On the revised Figure F-1, the only structure shown to remain is Glencoe Valley Road. However, it is the Division's understanding that, at a minimum, the NWRP diversion structure is expected to remain for reclamation. Therefore, please ensure all structures (from the revised Figure C-1 map) which are expected to remain for reclamation are shown on this map. d) Indicate all areas within the affected land to be retopsoiled and revegetated for reclamation. This should include all areas that have already been revegetated as well as current or new disturbed areas that will require revegetation for reclamation. 8) Please provide a separate Exhibit F map(or an inset on Figure F-1)showing a closer view of the Black Forest Mine area which portrays the expected physical appearance of the backfilled mine openings. This map should depict the approximate dimensions of the backfill area, show the approximate final slope gradients, and indicate areas to be retopsoiled and revegetated for reclamation. Exhibit L—Reclamation Costs (Rule 6.4.12): 9) The Division appreciates the operator providing a copy of the site-wide bond estimate associated with the Succession of Operators(SO-1)approved in 2018(Table L-1), as well as a separate bond estimate for the reclamation proposed in AM-5 associated with backfilling the Black Forest mine openings (Table L-2). It is the Division's understanding the operator plans to submit a Surety Reduction request in the near future, at which time, reclamation costs for the entire affected lands will be re-evaluated. In its review of AM-5, the Division will focus solely on the reclamation costs associated with the proposed expansion areas, including the plan to backfill the Black Forest mine openings. Accordingly, the following additional details are required in order for the Division to calculate the reclamation costs for the proposed backfill plan: a) Please provide the expected on-site location or approximate haul/push distance for the Fill Soil. b) Please specify the type of equipment to be used to extract/load the Fill Soil, to haul this material to the Black Forest Mine (if necessary), and to place this material for reclamation.
