// PAGE 7 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 Lands not otherwise occupied for developed water resources will be later developed to the highest possible end-use, and will likely comprise a mixed use which may include other general agricultural uses as well as light residential, commercial or industrial uses. Seeding - specify types, mixtures, quantities, and expected time(s) of seeding and planting; The balance of unoccupied affected lands above the anticipated static water level will be stabilized where necessary utilizing the seed mixture as shown as an addendum to Exhibit L – Reclamation Costs: Table L – Preferred/Primary Revegetation Seed Mixture. The Primary Revegetation Seed Mixture combines a thoughtful mingling of predominantly native grasses of diverse height, form, color and function, to assure that the reclaimed site can provide for a multiple-use benefit. Should post resource recovery land development be deferred, or even negated, all affected land remaining above the anticipated final water level of the resulting ponds will be stabilized with a diverse and durable cover of predominantly native grasses. This is compatible with, and an improvement over the diminished lands located in the floodplain of the two rivers, and area monocultures of residential bluegrass lawns and surrounding cropped land. Generally, warm and cool seed mixtures can be treated in a myriad of ways. In Table L this distinction is indicated in the column labelled “C/W”. Cool season mixtures are often planted in the fall and warm in the spring, however, exceptions may apply. Some argue warm season grasses are better broadcast, while others like them drilled with the cool season grasses. Resoiled areas will be allowed sufficient time to settle prior to seeding, which will commonly follow in the fall or spring. Resoiling will occur when soil moisture is adequate to prevent blowing, yet dry enough to prevent compaction. Part of the soil rebuilding process on the reconstituted soils will be in establishing structure to the soils to facilitate plant-soil-water relationships. Overly compacted soils will tend to limit soil structure development and create a poor seedbed for later establishment, so revegetation may be deferred if soils to be reclaimed are manipulated while wet, instead of moist. Fertilization - if applicable, specify types, mixtures, quantities and time of application; Fertilizer may be used as part of revegetation efforts. The need for fertilization and any subsequent fertilizer rates will be determined based upon soil tests taken at the time of reapplication of salvaged soil to affected lands remaining above water level. Status of fertilization and soil test results can be included in OMLR Annual Reports, as warranted. Sampling will utilize a hand auger and approved NRCS soil sample bags, and utilizing recommended procedures. Any soil testing will be conducted by the CSU Soil Laboratory in Ft. Collins, Colorado. The tests will be used to monitor soil quality and suitability of any amendments. Fertilizer may be withheld until after emergence to deter the encouragement of weed species. The use, composition and rates of fertilization will be determined prior to the time of seeding where appropriate, and may be reported in the OMLR Annual Reports, as appropriate. Revegetation - specify types of trees, shrubs, etc., quantities, size and location; and
