// PAGE 5 EXHIBIT D 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 Of the total 70.8 acres of potential extraction (e.g., the full eventual extents of P125_S1, P125A, and P125B), the resulting basins will function as multiple-use reservoirs with a slightly fluctuating combined water surface area covering 45.5 acres. Of the remaining balance of 25.3± acres of land above the anticipated high-water mark of the reservoirs, 10.4 acres of disturbed at-grade backfill, not otherwise committed to existing or planned structures or infrastructure over Pit P125_S1, will be stabilized with vegetation; the remaining 14.9 acres of basin slopes in Pits P125A and P125B will be stabilized with vegetation. Extraction will form a depression (basin) within the floodplain as shown in Exhibit C-2: Extraction Plan Map. Temporary above ground fill will be avoided but may occur within the floodplain, and as part of this permitted activity, provided the above ground volume does not exceed the below ground volume created by extraction. Such temporary fill could include topsoil, backfill or liner material placed for short durations pending placement in a final location. The floodplain extent will be visually marked in the field to better assure the integrity of the floodplain. Section (d) (d) the size of area(s) to be worked at any one time. The 196.4-acre parcel boundary forms the permit boundary, as reflected on exhibit maps. All lands under its direct control within the 196.4-acre permit area, are affected lands under C.R.S. 34-32.5-103(1), respective of this permit application. As a result, any changes required in the nature of planned extraction or reclamation will be made only through the Division of Reclamation, Mining and Safety (DRMS), by Technical Revision only. If lands are needed beyond the designated permit boundary, those lands will be secured for the active OMLR permit by Amendment. Within the permit boundary, there are three* (3) identifiable areas designated for primary extraction, the description of which will help to explain the nature of planned extraction and reclamation. The Primary Areas of Extraction are as follows: 10.4 Acres = Primary Extraction Pit P125_S1 – South Pit 22.1 Acres = Primary Extraction Pit P125A – Eastern Pit 28.2 Acres = Primary Extraction Pit P125B – Central Pit 60.7 Acres = Total Primary Extraction 135.7 Acres = Affected Lands beyond planned extraction limits 196.4 Acres TOTAL Of the outlying 135.7 Acres: 41.3Acres = Mineral Reserve Area The extraction limits assure through the use of setbacks that other interests are not affected by planned extraction. Extraction is set back uniformly at a minimum 10.0± feet from the edge of property lines; easements and rights-of-way; underground gas lines or other underground facilities, irrigation ditches and seep ditch, wells and other structures. Minor variations may occur in the field over time from those represented on Exhibit Maps. The plans detailed in this application are based upon future events for which minor or temporary departures at any point in time may be evident. To the extent any significant departure in the field occurs in a time and manner not otherwise anticipated in these exhibits, the operator may cure by self-inspection, by observation from DRMS inspection in a timely manner, or by operator-initiated Revision to the Permit or otherwise via clarification in attending required OMLR Annual Reports.
