Aggregate Industries, Morrison Quarry Amendment No. 7 to Permit M-1973-021 Morrison, CO October 2021 | 34 mulch, fertilizer, tackifier, and seed together in one application. Specific application rates for the fertilizer, seed, mulch, and shrub/tree planting frequencies can be found in the section titled Planned Reclamation Scope of Work, Item 11 below. Upon sustained, regenerative native grass establishment, shrubs and trees acclimatized to this area will be manually transplanted from local nursery stock. These will be in the form of containerized or tubeling trees and shrubs. Density of plantings and types to be used are those that have been previously discussed in permit amendments, and that are currently providing successful reclamation in the North Quarry. Refer to Exhibit F.4 for a diagram of where the various shrub and tree planting will be performed. Timed irrigation using "spaghetti tubing" with emitters has been practiced with success on tree and shrub plantings in the older parts of the North Quarry. This practice may be utilized for a maximum of 3 years to "wean" the plants to the natural meteorological cycle. Additionally, the operator has recently been experimenting with individual plantings designed to capture and retain natural moisture in the reclaimed portions of the Central Quarry with apparently good success. Irrigation practices will be at the discretion of the operator, but with the goal of an approximately 70% survival rate of trees and shrubs. The end-result of successful reclamation will provide wildlife habitat that mimics, as closely as possible, the pre-existing vegetative cover, using sustained revegetation. Upon final subsoil preparation at the former plant site, haul roads, and other un-mined areas, these areas will also be covered with topsoil and hydroseeded with the approved seed mixture and manually planted with trees and shrubs. To achieve a natural, pre-mining density of shrubs and trees, they will be replaced where and when necessary. Shrubs and trees (detailed in Exhibit F.6, Table 2) will be planted where they would be naturally found in this area. For example, Douglas 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/50 trees) 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 and cover 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.4. 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
