Specifications include, but are not limited to: The scope of work for the 2024 Dakota Collieries AML Project includes three sites which are identified on Figure 2. The West Site contains over 40 small subsidence and erosional features requiring filling from an onsite earthen borrow area. There is also one large erosional gully requiring rock rip-rap placement and two existing rock channels requiring additional rock rip-rap placement. The Central Site contains an abandoned highwall, final mine pit, and adjacent spoil piles. Approximately 115,000 cubic yards of soil material will need to be moved to backfill the highwall and mine pit.

Best Management Practices (BMP) must be used on site at all times, including silt fence, straw wattles, and erosion blankets.
