// PAGE 5 EXHIBIT E Raptor Materials, LLC Cogburn Sand, Gravel, and Reservoir Project February 2025 A Regular Impact (112) Construction Permit Application – Colorado Division of Reclamation Mining and Safety, Office of Mined Land Reclamation cover the anticipated exposed groundwaters of the basins in the unlined state. The entire unlined basin is or will be sufficiently covered under an approved Substitute Water Supply Plan. In order to again liberate waters set aside for augmentation, the basins will as soon as is practical be backfilled or lined to segregate the basin from Colorado groundwaters. The impacts of the proposed project on the prevailing hydrologic balance are discussed in Exhibit G – Water Information. 3.1.7 Groundwater – Specific Requirements A Groundwater Monitoring Plan is attached as an addendum to Exhibit G – Water Information. 3.1.8 Wildlife Wildlife safety and protection is discussed in Exhibit H – Wildlife Information. 3.1.9 Topsoiling Stripped topsoil that is not immediately used for reclamation will be stockpiled and stabilized with a cover of native vegetation as an erosion control measure. The topsoil stockpile location at the north end of Pit P125A is intended to allow for the complete extraction of Pit P125_S1 and the near-complete extraction of Pit P125A before relocation and/or application to reclaimed exposed surfaces. The quality of the on-site topsoil is detailed in Exhibits I and J – Soils and Vegetation. Section 2.D Where applicable, plans for topsoil segregation, preservation, and replacement; for stabilization, compaction, and grading of spoil; and for revegetation. The revegetation plan shall contain a list of the preferred species of grass, legumes, forbs, shrubs or trees to be planted, the method and rates of seeding and planting, the estimated availability of viable seeds in sufficient quantities of the species proposed to be used, and the proposed time of seeding and planting; Topsoil stockpiling, stabilization, and application is addressed in this Exhibit E – Reclamation Plan Sections 2.A, 2.C, and 2.F. Spoil stabilization, compaction, and grading is addressed in this Exhibit E – Reclamation Plan Sections 2.C and 2.F. A list of preferred seed mixes, application rates, and methods for revegetation is included as an addendum to Exhibit L – Reclamation Costs. The proposed time of seeding and planting is addressed in Section2.F. Section 2.E A plan or schedule indicating how and when reclamation will be implemented. Such plan or schedule shall not be tied to any specific date but shall be tied to implementation or completion of different stages of the mining operation as described in Rule 6.4.4(1)(e). The plan or schedule shall include: (The schedule need not be separate and distinct from the Reclamation Plan, but may be incorporated therein.) i. An estimate of the periods of time which will be required for the various stages or phases of reclamation;
