Aggregate Industries, Morrison Quarry Amendment No.7 to Permit M-1973-021 FN Morrison,CO fir will only be planted in the upper areas of the north-facing slopes of the reclaimed areas after final mining. For reclamation costs (see Exhibit L— Reclamation Costs), it is assumed 100 plantings (50 shrubs/50trees) per acre will be planted. In addition to hydroseeding as well as shrub and tree plantings, the operator proposes the use of available sources of wood debris and rock to provide nesting habitat along the reclaimed benches. Woody debris and rock structures are to be placed along benches at approximately 300-foot intervals as shown in Exhibit F.5. These structures include: • Free standing snags: Upright trees with root ball anchored below finish grade • Habitat root wad: Minimum 18-inch diameter tree laid on its side with the root wad partially buried • Brush log piles: Miscellaneous stumps and branches placed in 10-foot-diameter piles • Rock piles: To be placed along lower benches to provide protection for wildlife Schedule Reclamation will resume in the upper benches of the South Quarry in 2020-2021, after an access road leading to the West Quarry is built. The lower benches of the South Quarry will be reclaimed in an expedient manner as mining resumes. West Quarry reclamation will take place concurrently with mining, which is scheduled to begin in 2021. Mining and reclamation of the South and West Quarries is anticipated to end in 2043-2044.
