// PAGE 2 EXHIBIT I 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 Soil Unit #47. Olney fine sandy loam, 1-3% slopes; capability subclass IIIE irrigated & IVC non- irrigated; sandy plains range site description [H1 horizon = 0-10”] Soil Unit #51. Otero sandy loam, 1-3% slopes; capability subclass IIIE irrigated & IVE non- irrigated; sandy plains range site description [H1 horizon = 0-12”] The attending narrative descriptions in the included Soil Survey addendums and extracts, detail the native soils, vegetations, and associated ecological conditions likely prevalent over unaltered lands of like kind, and as they might present themselves over the identified parcels. The identified vegetation is an indicator of what did, or may, grow on the represented soils under native undisturbed soil conditions. This information is utilized to create the seed mixture(s) proposed under Exhibit L - Table L-1: Primary/Preferred Revegetation Seed Mixture. The species selected for reseeding are selected as offering the best genetic potential for establishment of a diverse and enduring stabilizing cover in the reclamation and restoration of the affected lands. The affected soils in the proposed extraction areas are designated under the soil survey to fall predominantly under Unit 3: Aquolls and Aquents, gravelly substratum; and Unit 41: Nunn clay loam, and minor components of Unit 1: Altvan Loam. Unit 3 and Unit 41 soils are considered as having potential with appropriate water management as being prime farmland and so well suited to the establishment and maintenance of plant growth in reclamation. While Unit 1 soils are not considered potentially as prime farmland, this unit occupies a lesser portion of the proposed extraction area however of note, the area has been demonstrated to adequately support agriculture. Soil salvage will commence with the removal of the surface layer of soil to a mean depth of 6.0± inches, depending upon equipment and equipment operator limitations. Additional depths of soil (to the extent it occurs) will be removed in a like manner until commercially viable overburden and aggregate are reached, unless already exposed as a result of poor soil development or flood based deposition. Soil salvage will be conducted primarily with excavators, but may include other heavy equipment such as bulldozers as warranted. To minimize the undesirable effects of soil blowing and loss, and to avoid damage to the soil resource via compaction, soil will be stripped wherever possible when soil is moist, and not dry or wet. Any portion of the salvaged soil suitable for plant regrowth will be utilized to meet the minimum depth of soil replacement for reclamation, with the excess made commercially available for export from the property. Generally, soil will be retained in sufficient volume to reclaim all lands remaining between the anticipated static water level of the basins and existing access roads which surround them at any given point in time during resource recovery operations. Once removed from its native location, soil retained for reclamation will be stockpiled over the northern corner of Pit P125A, in areas above the floodplain; or otherwise windrowed along the perimeter of the basin area of extraction or area to be resoiled and seeded with the reclamation seed mixture specified under Exhibit L - Table L-1: Primary/Preferred Revegetation Seed Mixture, or as otherwise determined under an approved revision. Stabilization of inactive soil stockpiles will provide an opportunity to gauge the performance of the seed mixture while attempting to provide a stabilizing cover of vegetation over the stockpiled soil until it is ready for replacement on finished slopes and affected lands remaining above the anticipated static water level of the completed reservoir basins.
