J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application EXHIBIT D Mining Plan Mining Limits J-2 Contracting proposes to mine in the land located in the E 1/2 of NW 1/4, the NE 1/4 of the SW 1/4, the E 1/2 of the SW 1/4 of the NW 1/4, and the E 1/2 of the NW 1/4 of the SW 1/4 of Section 3, Township 5 North, Range 65 West of the 6th Principal Meridian, County of Weld, State of Colorado and that part of the SE 1/4 of the SW 1/4 and the E 1/2 of the SW 1/4 of the SW 1/4 of Section 3, Township 5 North, Range 65 West of the 6th Principal Meridian, County of Weld, State of Colorado lying North of the Eighth Street Road except that portion described in deed recorded September 24, 1982, at reception no. 1904628, Weld County, Colorado. The proposed mining site is located adjacent to the City of Greeley city limits on the north, east, and south property lines, as well as being adjacent to 8th Street on the south property line. The Cache La Poudre River is approximately 700 feet south of the site on the south side of the permit boundary. 8th Street is immediately adjacent to the west side of the permit boundary. Access to the site will be located at the southwest corner of the permit boundary off of 8th Street. The dominant land use surrounding the property is agricultural and industrial. An aggregate processing plant and recycle crushing area will be located in Phase 1, and a future concrete and asphalt batch plant area will be located within the Phase 2 mining area as shown on the Mining Plan Map. These areas will contain stockpiles, portable equipment, storage bins, and silos as necessary to support the plant operations. Concrete truck washout and excess concrete product dumping will be included in the future Phase 2 area to ensure that waste materials are recycled and kept from entering the stormwater flows on the site. The concrete truck washout area will be a 30 -foot by 20 -foot three cell concrete structure. Concrete trucks will wash the residual product from their mixing drums and chutes into the first cell of the structure. The first cell spills into the second cell, which spills into the third cell. This allows the aggregate and suspended fines to settle into the cells over time. The water and settled material in the three cells are then removed as required and recycled into the concrete batch plant. Generally, the cells would be cleaned on a weekly schedule. The excess product dumping area will be approximately 50 feet by 100 feet and have an exterior berm to limit the migration of stormwater flows to and from the surrounding areas. Excess product that is deposited in this area will be allowed to cure for approximately 90 days until it becomes inert. It will then be crushed and recycled. All local, State, and Federal rules and regulations will be followed for the storage and handling of any fuel, asphalt, cement, flyash, and admixtures required for the batching facilities. The permit boundary will encompass approximately 85.17 acres which will all be affected acreage, and approximately 72.10 acres being mined. The remaining area will consist of access roads and disturbed land. The following table depicts the different affected acreage: Jai' Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application Affected Acreage Mining Plan Area (acres) Mined Area 72.10 Access Roads 0.70 Disturbed Land 12.37 TOTAL 85.17 Various setbacks from adjacent roads, adjacent structures, and oil and gas infrastructure will be maintained as mining occurs. All setbacks specified in the surface use agreements with the oil/gas companies will be followed. The final executed agreements are expected to be obtained in the near future and will be forwarded to the Division when they are available. A minimum 200 foot setback from any existing oil/gas facility will be maintained until that time. See Exhibit C, Mining Plan Map, and the Slope Stability Report for the mining limit configuration and information on setbacks and their locations. The mineral deed (attached) also requires that no surface facilities are to be located on this property. The abandoned wells would be cutoff after mining has reached the bedrock surface or the reclaimed slope surface where a new cap and any additional concrete for the existing plug would be needed. McCarty Engineering, LLC has provided this service for J-2 Contracting and at other mining permit locations for other operators. They are licensed and bonded to obtain approvals from the COGCC to do these types of re -plug services on abandoned oil and gas wells. Products Sand and gravel will be the primary product produced from the Sunset Industrial Pit. The principal intended use for the sand and gravel is for road base and construction aggregates. Subsurface drilling and testing have verified that the Sunset Industrial Pit property contains a significant commercial deposit of sand and gravel. The depth of interbedded sandy clays and clayey to silty sands at the surface range from 0 to 14 feet. The thickness of the aggregate material ranges from 40 to 107 feet where bedrock contact occurs. Mining Methods The deposit will be dry mined and slurry walls will be constructed around the perimeter of the mining area for Phases 1 and 2. Mining will not expose groundwater prior to the slurry wall being constructed around each phase. Design specifications for the slurry wall and quality control procedures used during construction will ensure that the reclaimed reservoir meets State Engineer's Office (SEO) performance standards. Dewatering trenches will be excavated around the perimeter of each mining area prior to mining operations commencing. The depth of the ditches will vary as the mining progresses deeper into the alluvium in order to maintain the groundwater level below the active mining bottom surface, and therefore minimize the exposed groundwater surface area. The dewatering ditches will flow to a collection pond, from which the water will be pumped and discharged into recharge areas where overflow will reach a culvert that crosses 8th Street into the Ogilvy Ditch and ultimately reach the Cache La Poudre River. The equipment and facilities may include, but are not limited to the following: L JaT Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application Processing Equipment Screens, wash plant, crusher, conveyors, stackers, and other miscellaneous processing equipment. Earth Moving Equipment Dozers, loaders, scrapers, excavators, and compactors will be used for mining and earth moving operations. Miscellaneous Equipment Dewatering pumps, electrical trailer, generator trailer, small portable generators and watering trucks will be used as needed. As mining progresses, topsoil and overburden will be stripped to expose the aggregate product below. All soil and overburden material will be used on -site for reclamation; so long-term stockpiling of these materials is not anticipated. Overburden stockpiles will be located within the proposed mining area. The stockpiles will be placed parallel to the floodplain to mitigate impacts to the floodplain. Mining of the aggregate will progress down to the underlying bedrock. Since reclamation will occur concurrently with mining, it is not anticipated that overburden material will be stockpiled long-term prior to use in production of road base. During mining the mining face for Phases 1 and 2 will have a 3H:1V slope to bedrock or the bottom of the future reclaimed reservoir. The processed aggregate material will be temporarily stockpiled near the portable processing plant. Recommendations for monitoring of slope stability, including, conducting a visual inspection of the excavated slopes on a weekly basis for the duration of mining, conducting a visual inspection after a major precipitation event that has saturated the ground using the same procedures, contacting qualified personnel to evaluate and recommend remediation work to stabilize the area in the event a visual inspection detects signs of potential slope failure, and if no visible signs of slope failure are detected during mining, reducing visual inspections to once every six months after mining completion, or after every major precipitation event. All local, State, and Federal rules and regulations will be followed for the storage and handling of any fuel for the facilities. Topsoil Handling Plan As stated previously the topsoil will be stripped to expose the aggregate product underlying the topsoil. The topsoil will be stripped using scrapers and stockpiled in the topsoil stockpile as depicted in Exhibit C. The volume of topsoil for all the mining phases is approximately 115,000 cubic yards. The depth of the topsoil is approximately twelve inches over the majority of the mining area. The topsoil will be stripped and stockpiled during each phase of mining where topsoil will only be removed for Phase 1 and Phase 2 as they are going to be mined. The height of the topsoil stockpile will be approximately 15 feet. Mine Phasing J-2 Contracting anticipates mining and reclaiming the Sunset Industrial Pit in 2 phases, progressing through the phases as shown on the Mining Plan Map. The overall time required to complete the mining and reclamation is estimated to be 12 years based on an average rate of L JaT Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application 650,000 tons per year. The initial production is expected to be 300,00 tons per year with the maximum production expected to be 1,000,000 tons per year. However, it is possible that due to demand fluctuations, mining could progress slower than anticipated and additional time may be required for mining and reclamation of the site. The operator is proposing to mine Phase 1 first. Phase 1 is 64.22 acres and the estimated time for mining Phase 1 is approximately 9 years and 6 months.. The operator is proposing to mine Phase 2 second as the area is currently being permitted as an RV storage site so this area will not be mined until after Phase 1. During the mining Phase 2 a slurry wall will be installed around the perimeter of Phase 2 prior to exposing groundwater. Phase 2 is 20.95 acres. The estimated time for mining Phase 2 is approximately 2 years and 6 months. The mining will progress in each phase beginning at the outer edge of the phase where material will be moved toward the interior of the phase such that the mining slope can be established. The mining slope will be established for the entire perimeter of the phase in 3 to 6 feet intervals. Dewateri ng Dewatering trenches will be placed along the perimeter of each mining area in Phases 1 and 2. The dewatering trench around the perimeter of the phase being mined will be placed at the toe of the mining slope. As the phase is mined deeper the dewatering trench will be lowered and moved laterally along the mining slope toward the center of that phase. Slurry walls are anticipated to be installed around the perimeter of Phases 1 and 2 prior to exposing groundwater and mining will continue to commence in those phases and it is expected minimal dewatering will be required after the slurry walls are installed due to the slurry walls cutting off groundwater infiltration into the pit. J-2 Contracting Company will have an approved substitute water supply plan and well permit prior to exposing groundwater. The substitute supply plan will be updated annually to account for water that is consumed due to exposing groundwater by the mining operation. Explosives Explosives will not be used during mining. JaT Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application EXHIBIT E Reclamation Plan Lined water storage reservoirs will be the final reclaimed use for the Sunset Industrial Pit. Portions of mining areas will be reclaimed as "native" areas, which will be re -seeded with native vegetation. The majority of the mining areas will be reclaimed as water storage reservoirs. The remaining area within the proposed permit boundary will consist of reservoir shoreline, unimproved access roads around the reservoirs, and reclaimed vegetated land. Final Land Use Reclamation Plan Area (acres) Reservoir Water Surface 53.60 Access Roads 9.70 Reclaimed and Slopes Vegetated above Reservoir Land (Disturbed Water Surface) Land 21.87 TOTAL 85.17 Water Storage Reservoir In general, the mining limits will be mined down to the shale/claystone/sandstone bedrock. The relatively impermeable bedrock will make the bottom of the reservoir. The reservoir will be separated from the surrounding alluvial aquifer by the slurry wall liner system as detailed in the cross-section shown on the Reclamation Plan Map. The slurry wall liner will be keyed into the bedrock material and extend upward through the height of the alluvium at the bench depicted in the mining plan. A clay liner will be installed above the slurry wall to complete the liner design/construction from the bench elevation to three feet above the reclaimed normal water surface elevation. Design specifications and quality control procedures used during the construction of the slurry wall liner and clay liner will ensure that the reservoir meets the State Engineer's Office (SEO) performance standards for permeability. All reservoir slopes will be reclaimed to at least 3H:1 V final grade Since reclamation will be concurrent with mining, most soil, overburden, and bedrock material excavated during mining will be used almost immediately. Scrapers and dozers and compactors will be used to shape the reclaimed slope material along the reservoir perimeters to achieve the final grade. Upon placing the backfill material, 95 percent compaction will be achieved to ensure adequate integrity of the clay liner above the bench, backfilled areas for haul/access roads and recharge pond areas that are not within the future water storage/reservoir footprint. Final reclamation by capping with topsoil and re -vegetating above the expected reservoir water level will follow grading operations as well as backfilled areas that will not be haul/access roads to minimize the amount of disturbance at any one time. Recommendations for monitoring of slope stability, including, conducting a visual inspection of the excavated slopes on a weekly basis for the duration of mining, conducting a visual inspection after a major precipitation event that has saturated the ground using the same procedures, contacting qualified personnel to evaluate and recommend remediation work to stabilize the area in the event a visual inspection detects signs of potential slope failure, and if L JaT Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application no visible signs of slope failure are detected during mining, reducing visual inspections to once every six months after mining completion, or after every major precipitation event. During reclamation activities, inlet and outlet facilities for the reservoir will be designed and installed once the operational criteria of the proposed reservoir have been identified by an end user. Reclamation Measures/Materials Handling Backfilling will be done to provide stabilized shorelines around the reservoir and to minimize erosion. The backfill material will consist of gravel, overburden, clay, and topsoil. There will not be known toxic or hazardous materials in the backfill material. Additionally, it is not likely that acid forming or toxic materials will be encountered during mining. The mining will not leave high walls on the property. In addition, there will be no auger holes, excavations, or shafts left on the property. Topsoil will be placed to finalize the grading such that seeding can occur. The topsoil will be placed at all disturbed areas and on the mining slope to an elevation matching the expected reservoir water level. Topsoiling Approximately the top six inches of soil on the property is classified as topsoil. This layer includes the root zone of grasses and crops, which will be stripped and stockpiled separately. By using concurrent reclamation techniques, the topsoil is not expected to remain in stockpiles for more than one to five years. If the stockpile remains more than one growing season, it will be seeded with a fast-growing vegetative cover to prevent erosion. All topsoil will be retained on - site to reclaim the reservoir shoreline, and other areas disturbed by mining activities. Where required, topsoil will be replaced to a depth of twelve inches. Revegetation As mining operations are completed, areas for reclamation will be graded and shaped for revegetation. Runoff or excess water from adjacent areas will not be allowed to flow over slopes being graded and seeded. If needed, berms or channels will be constructed to divert excess water and convey it in a safe and non -erosive manner. For disturbed areas, the reclamation plan includes re -vegetating with appropriate seed mixes to minimize erosion and re-establish natural terrain. The seed mixture below was selected to be long lasting and regenerating, as recommended by the Greeley Natural Resource Conservation Service Office (see attached recommendation). The ground will be fine graded prior to seeding and mulch will be applied according to recommendations from the NRCS. Reservoir side slopes below the anticipated reservoir water level will not be seeded. The proposed seed mix is shown in the following table. JaT Consulting, Inc.

If seed is to be broadcast, the application The seed mix for final reclamation as described above does not require fertilizer as recommended by the local NRCS office in Greeley, Colorado. The seeded areas will be covered with dead crop litter from sorghum or milo crop forage, or with straw mulch at a rate of 4,000 pounds per acre. If a significant invasion of noxious weeds occurs after seeding, the weeds will be mowed before they can go to seed. The areas will be mowed periodically for additional control as needed. Mechanical control will be used as a first priority. Chemical methods will only be used if no other alternative produces acceptable results. For temporary earthen stockpiles, the reclamation plan includes re -vegetating with appropriate seed mixes to minimize erosion and establish more rapidly to stabilize the stockpiles. If a temporary earthen stockpile remains more than one growing season, it will be seeded with the seed mix below to prevent erosion. The grass mixture below was selected as recommended by the Greeley NRCS field office. The proposed seed mix is shown in the following table.

Water — General Requirement To minimize the effect on the prevailing hydrologic balance, J-2 Contracting Company will: a. Comply with all applicable Colorado water laws. b. Comply with all applicable Federal and State water quality laws and regulations. c. Comply with all Federal and State requirements for dredge and fill. 64111 JaT Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application d. Re -grade and backfill all sediment and siltation structures after mining is completed. e. Monitor groundwater levels adjacent to the site and mitigate any damage to adjacent wells that dewatering activities may have. (See Exhibit G) Groundwater — Specific Requirements The operation will not affect groundwater quality on or off the site. The operation will comply with State groundwater quality standards. The mining and reclamation may affect the groundwater table surrounding the mine site. The proposed mitigation efforts to minimize these impacts are recharge ponds or ditches in necessary areas to maintain groundwater levels during the mining, and a perimeter drain if needed to convey groundwater around the lined reservoir after the pit side liner is installed. A ground water model by McGrane Water Engineering, LLC has also been provided and the results indicate that water levels will be affected by +1-1 ft and there are not any wells within the predicted water level change so the overall impact of the slurry wall and clay liner will be insignificant. J-2 Contracting Company proposes that they monitor groundwater levels through both interior (within phases of the mining) and exterior (outside the slurry wall lining) monitoring wells that they have installed, or have access to before, during, and after the mining and reclamation is complete so that impacts to the groundwater table, from this mining operation, can be identified and addressed. It is the intent of J-2 Contracting Company to operate responsibly and to mitigate any damage to wells that is directly attributable to the mining and reclamation of this site. Reclamation — Approximate Time Table The initial proposed rate of production for the mine is 300,000 tons per year and the maximum proposed rate of production for the mine is 1,000,000 tons per year. The total time frame to mine all phases assuming an average production rate of 650,000 tons per year is approximately 12 years. The following table shows the approximate time frame to finish each phase of mining assuming an average production rate of 650,000 tons per year: Mine Phase and Acreage Time Frame to Complete and Reclaim Phase Phase 1 — 64.22 acres 9 years and 6 months Phase 2 — 20.95 acres 2 years and 6 months The assumed annual production rate is 300,000 tons initially to 1,000,000 tons maximum for processed material leaving the mine each year. The size and area of reclamation varies for each phase but generally consists of the outside mining slope in phases 1 and 2 being reclaimed at a 3H:1V slope with the addition of clay, overburden, topsoil, and revegetation. For more information on sequencing and size of the reclamation activities refer to Exhibit L financial warranty calculations. sign JaT Consulting, Inc.

J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application EXHIBIT G Water Information Introduction The Sunset Industrial Pit mining site is located in the E 1/2 of NW 1/4, the NE 1/4 of the SW 1/4, the E 1/2 of the SW 1/4 of the NW 1/4, and the E 1/2 of the NW 1/4 of the SW 1/4 of Section 3, Township 5 North, Range 65 West of the 6th Principal Meridian, County of Weld, State of Colorado and that part of the SE 1/4 of the SW 1/4 and the E 1/2 of the SW 1/4 of the SW 1/4 of Section 3, Township 5 North, Range 65 West of the 6th Principal Meridian, County of Weld, State of Colorado lying North of the Eighth Street Road except that portion described in deed recorded September 24, 1982, at reception no. 1904628, Weld County, Colorado. The proposed mining site is adjacent to the City of Greeley city limits, and adjacent to 8th Street. The Cache La Poudre River is approximately 700 feet south of the site on the south side of the permit boundary. 8th Street is immediately adjacent to the west side of the permit boundary. Access to the site will be located at the southwest corner of the permit boundary off of 8th Street. The operation will consist of sand and gravel production and will impact the Cache La Poudre River in the form of depletions due to evaporation and operational losses associated with mining. Mining of the Sunset Industrial Pit mining site will last for approximately 12 years. Once reclamation is complete reservoirs will be created with a total surface area of Reservoir 1 being 41.89 acres and Reservoir 2 11.71 acres. The depth to groundwater ranges from 18 to 40 feet within the permit boundary (measured in MW -1 through MW -5, See the attached piezometer measurements table). The site will be mined down to a depth of 40 to 112 feet thus exposing groundwater to the atmosphere. This exposed groundwater, along with the operational losses associated with the extraction of sand and gravel deposits, will impact the Cache La Poudre alluvial aquifer. These impacts will cause river depletions that must be augmented. Groundwater will be exposed during the mining once the mining depths reach an elevation of approximately 4614. To enable dry mining at the Sunset Industrial Pit mining site, there will be dewatering trenches around the various phases of the site. These dewatering trenches will change in length throughout mining. The maximum length will occur when one phase is completely mined, but before the reclamation has begun on any given phase. The maximum size of dewatering trench will be 3,000 feet long and 5 feet wide, or 0.33 acres of exposed surface area. This water will be collected in a recharge pond totaling 3.5 acres. The water will be pumped into dewatering ditch, which traverses the site, into a recharge pond and ultimately into the Cache La Poudre River. As mining progresses, the dewatering trenches will shift as various cells are reclaimed. The gravel pit will have a slurry wall liner being constructed as mining commences in Phase 1. Water Requirements Water use at the Sunset Industrial Pit mining site will include evaporation from exposed groundwater, dust control of haul roads and stockpiles, and water retained in material removed from the site. J tT Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application Evaporative Loss Evaporative losses are dependent on the exposed water surface area, which may shift throughout the mining operation, but will not exceed the maximum. Exposed surface area at the Sunset Industrial Pit mining site will include groundwater exposed in the dewatering trenches and recharge pond. The maximum exposed surface area at the site during mining is estimated at 3.83 acres. J-2 Contracting Company plans to keep the site dewatered throughout the life of the mine. Evaporation data was taken from NOAA Technical Report NWS 33, Evaporation Atlas for the 48 Contiguous United States. The annual gross evaporation was determined to be 45 inches for this location. Monthly evaporation percentages are established by guidelines set by the State Engineer's Office. To determine precipitation, data from the National Weather Service for Greeley, CO (UNC) (1967-2022) was used. The long-term average precipitation at the Sunset Industrial Pit mining site is estimated at 14.69 inches. Effective precipitation is calculated as 70% of the total precipitation. The net evaporation is the difference between gross annual evaporation and effective precipitation. The resulting net evaporation is 2.52 feet. The maximum evaporative loss from the 3.83 acres is 9.67 ac -ft. Operational Loss The average annual production from the Sunset Industrial Pit mining site is estimated at 650,000 tons. Using 4% moisture content, the total associated consumptive use for water retained in the material mined is 19.95 ac -ft. Dust control use is 10,000 gal/day, 6 days/week, 4 weeks/month for 10 months of the year. This equates to 7.4 ac -ft. Maximum annual operational loss is estimated to be 27.35 ac -ft for Phase 1. Consumptive Use The maximum annual consumptive use (operational loss + evaporation loss) at this site during the mining operation is estimated to be 37.02 ac -ft for Phase 1. Replacement Water The replacement of consumptive uses at the site is will be accounted for in a substitute water supply plan (SWSP) approved by the State Engineer. The SWSP will be obtained prior to any mining activities occurring that expose groundwater. Surrounding Water Rights The attached Figure A-1 Well Permits in the Sunset Industrial Pit — Groundwater Evaluation by McGrane Engineering, LLC shows the permitted wells within 600 feet of the mining limits and permitted wells within the boundaries of the groundwater model/evaluation. The well information and locations were obtained from the Division of Water Resources online mapping well permit locator. This well and water rights information was cross checked with the State's CDSS. J&T Consulting, Inc.

If the proposed use of groundwater at the Sunset Industrial Pit mining site results in material injury to surrounding wells, J-2 Contracting Company will ensure that all necessary measures are taken to address the issues. Water Quality An NPDES permit will be obtained from the Water Quality Control Division at the Colorado Department of Public Health & Environment for the Sunset Industrial Pit mining site prior to discharging any groundwater that is dewatered from the site. This permit will be kept current and amended as necessary to ensure that any water discharged from the site will meet the permitted water quality standards. Impacts to Groundwater/Hydrologic Balance J-2 Contracting Company will monitor the groundwater levels surrounding the site and provide groundwater recharge if necessary via perimeter ditches/ponds. J-2 Contracting Company will construct these ditches/ponds in the locations where direct discharge to an existing adjacent irrigation lateral is not available to ensure that stabilized groundwater levels are maintained. They will discharge dewatering flows into existing adjacent irrigation laterals where possible to limit the disturbance to the surrounding land. Slurry wall liners are proposed around the individual phases and will likely be installed either shortly after mining has begun or prior to mining starting. Ja6T Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application To summarize the mitigation process, as each phase of mining/dewatering occurs, J-2 Contracting Company will monitor the groundwater levels adjacent to mine as each phase progresses. If groundwater levels drop to a level that prevents an adjacent well from performing acceptably, according to that well's owner, J-2 Contracting Company will either implement a groundwater recharge ditch/pond near the well in order to raise the groundwater level in the vicinity of the well and hence return it's operation to acceptable standards, or will negotiate an agreement with that well owner to replace the well or provide replacement water via other means until the mining and reclamation activities are concluded but it is not anticipated that any groundwater levels will drop since the slurry wall for each phase will be installed prior to exposing groundwater. Groundwater wells that are not owned by J-2 Contracting Company or Sunset Industrial, LLC (Table G-1) are potentially located within 600 feet of the mining limits. The exact physical location of these wells will be determined during the SWSP and well permit application processes. If wells are found to be within 600 feet of the mining limits, J-2 Contracting Company will either obtain a well waiver from the owner of the well, or provide an agreement with the well owner that J-2 Contracting Company will mitigate and material damage to the well that is directly attributable to the mining and reclamation of the site. All other wells within 600 feet of the mining limits are either owned by Sunset Industrial, LLC, or are monitoring wells therefore groundwater impacts to these wells do not need to be addressed.

Lupton, CO 80621 RE: Fair Meadows Pit — Groundwater Evaluation Dear Mr. York: McGrane Water Engineering Via email at: jcyorkc�jj-tconsulting.com The proposed Fair Meadows gravel pit mine is located approximately 2 miles east of Hwy 85 in Greeley, Colorado in Section 3, Township 5 North, Range 66 West (6t' PM). The site is located approximately 1000 feet north of the Cache la Poudre (Poudre) River. Figure Al shows the site, and approximately 122 permitted wells located within approximately 1.5 miles of the site. As part of the mine permit application process, the mine consultant, J&T Consulting, Inc. (J&T) requested that McGrane Water Engineers, LLC. (MWE) determine the potential impacts of a slurry wall around the proposed Fair Meadows pit. Impacts typically include a rise in the water table on the up -gradient side of the slurry wall and a decline in the water table on the down gradient side. Water level increases to within 10 feet of the surface on the up -gradient side of the pit could also cause flooding of low lying structures such as basements. A decline in water levels on the down gradient side could reduce the aquifer saturated thickness and well yields if the decline is significant as discussed below. GROUNDWATER INVESTIGATION To evaluate the groundwater impacts, we: 1. Conducted a literature search of existing published groundwater literature in the vicinity of Greeley, Colorado; 2. Compiled well data from the State's Well database (CDWR, 2022) including: well name, permit number, location, well depth, depth to water, and pumping rate (Table Al); 3. Compiled well data from a geotechnical evaluation conducted by CMT Technical Services dated September 23, 2022 (Appendix B) 4. Evaluated compiled monitoring well water levels taken around the pit by J&T which shows the seasonal water level fluctuations are approximately 2-4 feet (Table A-2); 5. Evaluated seasonal water level changes observed in 15 registered wells over the past two years (Table A-3); 6. Created a groundwater model to evaluate potential changes in groundwater levels resulting from a slurry wall around the mine; and 7. Prepared this letter report which includes numerous figures that characterize the aquifer and support the results. Fair Meadows Pit Groundwater Evaluation November 19, 2022 Page 2 of 28 A detailed discussion of the Hydrogeologic analysis, model parameter selection and assumptions, and discussion of the model results and their sensitivity and uncertainty are included in Appendix A - Groundwater Evaluation and Modeling. Results We used the USGS MODFLOW2000 (Harbaugh et al, 2000) modeling program to evaluate the existing and future groundwater conditions at the Fair Meadows pit. Using reasonable boundary conditions and aquifer properties, the model predicts that water levels will rise up to +2.5 feet on the up -gradient (northwest) corner of the pit (Figure A9). Mounding up to 1 ft high can be expected within approximately 1000 feet north and west of the mine property. The downstream shadowing effect is constrained within an approximately 1,000 foot wide zone between the pit and the Poudre River, and shadowing does not exceed approximately -1.5 ft. There are no registered production (non -monitoring) wells that are within the area of +1- 1 foot change. Well permit no. 28964 registered to Robert Davis is located in the northwest corner of the Mine property. However, according to the mine engineer (J&T), the Davis property is now owned by the mine and they intend to abandon the well. To evaluate potential high water caused by the slurry wall, we identified 16 registered wells that have reported water level depths (when drilled) less than 10 feet deep. Of these, only well permit 2020-F, belonging to the Summit Group of Southern Wisconsin, is within the zone of expected water level rise of between +0.5 and +1 ft. There are six registered wells that are currently being monitored by Broken Arrow Investments (BAI) that are within the area of expected mounding of 0.5 to 1.0 ft. None of these wells have measured water levels shallower than 11 ft so no impact is expected. Well 374-WCB (Davis Farms) is the only other up -gradient well with an expected rise in the water table between +0.5 and +1.0 ft. The Davis well is reportedly 86 ft deep, with a measured water level of 31 ft when drilled. It reportedly can pump approximately 1200 gpm, one of the highest within the model area. The expected rise in water level will likely benefit production by increasing the aquifer saturated aquifer thickness and available drawdown. Considering that the seasonal water table fluctuates approximately 2-4 feet, and there are no registered wells located within the predicted water level change of +1- 1 ft, we believe the overall impact of the mine slurry wall will be insignificant.

The site is located approximately 1000 feet north of the South Platte River (SPR). Figure Al is a Google Earth image that shows: the pit property, permitted wells color coded by use, pit monitoring wells MW - 1 through MW -5 and the model/study area boundary. Available Data We compiled hydrogeologic data from: • Existing reports from the US Geological Survey and Colorado Division of Water Resources (see Sources below); • Well completion reports from the State's Well database (SEO wells) within approximately 1.5 miles of the proposed pit; • This includes 15 registered wells that are currently being monitored by J&T to evaluate water level changes in response to other recently constructed Loloff and Derr pits located west of the Fair Meadows pit; and • 5 Fair Meadows Monitoring wells provided by J&T. Table Al includes well data from 122 registered wells extracted from the State's well database (CDWR, 2022). Most of the existing wells are used for domestic water supply and irrigation. Data includes: the well owner, permit number, well type, Colorado State Plane coordinates, registered "use" type, well depth, well yield in gallons per minute (gpm), water level when drilled and depth to bedrock. The reported well depth and depth to bedrock are slightly different but the depth to bedrock is a more accurate indicator of the bottom of the alluvial aquifer. Well statics for all the wells is shown at the bottom of the table. The depth to bedrock ranges from 15 to 134 ft and averages 65 feet. Well yields range from 7 gpm for domestic wells to 1200 gpm for irrigation wells. The depth to water when drilled ranges from 2 to 50 feet and averages 24 feet. Table A2 shows monitoring well data for the five Fair Meadows borehole monitoring wells. The wells were drilled by Cesare, Inc./CMT Technical Services to characterize the site. Details on drilling, materials encountered, well construction and water level information can be found in the report included in Appendix B. The average site depth to bedrock is 85 ft and depth to water is 29 ft which are greater than the model area average. Monitoring Registered Wells Up -Gradient There are two other gravel pits that have been developed in the past 5 years located upgradient from the site. The Loloff Pit was lined in 2017 and the Derr Pit was lined in 2020. Broken Arrow Investments (BAI) is responsible for monitoring 15 neighborhood wells for these projects, and J&T provided us the data to help characterize the aquifer. Monthly water level depth measurements since September, 2019 are shown in Table A3. In summary, the data shows that water levels fluctuate 2- 4 feet due to a combination of: i) general recovery from Loloff and Derr dewatering prior after installing their slurry walls; ii) water level changes caused by the slurry McGrane Water Engineering, LLC 1669 Apple Valley Rd. • Lyons, CO 80540 • Phone: (303) 917-1247 E -Mail: dennis@mcgranewater.com Web: ttp://www.mcgranewaterengineering.corn Fair Meadows Pit Groundwater Evaluation November 19, 2022 Page 5 of 28 walls; and iii) seasonal fluctuations in the water table due to agricultural pumping and irrigation return flows. Hydrogeology The hydrogeology of the SPR alluvial aquifer is described by Lindsay and Others (1998 and 2005), CDM (2006 and 2013) and CSU (2013). Figure A2 shows the site surficial geology (Tweto, 1979). The alluvium within the model areas consists of alluvial sand and gravel (Qa) adjacent to the modern SPR flood plain, and older terrace alluvium (Qg) outside the floodplain. Bedrock consist of the Laramie Formation (K]), which is primarily a black shale that is exposed beyond the northeastern corner of the model. Figure A2 also shows the well data permits and reported well depths. Wells with a less than (<) sign represent wells that did not encounter bedrock based on their driller's logs. The deepest portion of the surficial sand and gravel is over 100 feet deep and extends north from the Fair Meadows and other existing pits (pink triangles). This suggests that the modern alluvium (Qa) mapped by Tweto likely extends further north than what is shown on the Figure A2. Bedrock Elevation Contours Figure A3 shows the calculated bedrock elevation based on the ground elevation minus the reported depth to bedrock from a "driller's" log. The data was used to update the bedrock elevation contours (aka. structure map) published by the USGS (Hurr and Schneider, 1972). The map shows a deep (over 100 foot deep) erosional "paleochannel" extending from the northwest to southeast across the study area. The depression was eroded into the bedrock by the Poudre River thousands of years ago before the river established its current depositional channel and modern floodplain. The bedrock elevation within the paleochannel drops from approximately 4600 ft in the west to approximately 4530 feet in the east. The Fair Meadows pit is located where the elevation of bedrock drops steeply from 40 ft deep in the southwest corner to over 90 ft deep in the east. Water Level Contours We created a water table map (Figure A4) using available data from registered SEO wells (Table Al), Fair Meadows monitoring wells (Table A2), and the September 2022 measurement from the monitored registered wells (Table A3). The water table elevation data from SEO wells was determined by subtracting the reported depth to water when drilled from well site elevations interpreted from US Geological Survey lOm Digital Elevation Model (DEM) data sets. The ground elevations for wells in Tables A2 and A3 were surveyed. The 10 ft elevation contour lines shown on Figure A4 are a manual interpolation of the well data and river elevations. The water table on the western portion of the model is at an elevation of approximately 4630 ft and the water table gradient falls approximately 25 feet to approximately 4605 ft on the east end of the model. Groundwater flows perpendicular to the contours and generally towards the river. The Poudre River gains in the western side of the map between the 4630 ft and 4620 ft contours and loses between the 4620 ft and eastern edge of the model area. The location of the 4610 ft contour is heavily influenced by the Fair Meadows monitoring wells which appear to have water levels several feet below other nearby wells, which likely is the result of late season irrigation and stock well pumping.

Figure AS shows how the saturated aquifer thickens from only 40 feet on the west side of the Fair Meadows pit to over 90 feet on the east side within the paleochannel. Well Yield We plotted reported well yields extracted from the State's well database on Figure A6. All of the high capacity municipal and irrigation wells that produce over 1000 gpm (blue) are located in the northern half of the study area where the aquifer is thickest. Well yield is proportional to the aquifer saturated thickness which is expected to slightly increase up -gradient from the Fair Meadows (after it is installed) which will slightly benefit well production in the area, but not an appreciable amount. Aquifer Transmissivity Figure A7 shows the contoured aquifer transmissivity (T) which is the product of the aquifer hydraulic conductivity (a measure of permeability) multiplied by the saturated thickness (Figure AS). The resulting transmissivity distribution used in the model is consistent with USGS mapped values of 200,000 to 400,000 d/fI) within the paleochannel and across the Fair Meadows pit site. To obtain the contoured transmissivity values shown in Figure A7, we multiplied the saturated thickness shown in Figure AS by the hydraulic conductivity. We assigned a constant hydraulic conductivity of 600 ft/day in the middle of the paleochannel which created modeled transmissivity values that closely match the published transmissivity map by the US Geological Survey (Hurr and Schneider, 1972). We used a lower hydraulic conductivity (K) of 300 ft/day on the north and south sides of the paleochannel to represent older terrace deposits. This resulted in lower transmissivity values (<100,000 gpd/ft). The K values we used (300 - 600 ft/day) is a reasonable range for sand and gravel deposits. The range is also consistent with values used by the Colorado Division of Water Resources (250 to 550 ft/day) for the South Platte Decision Support System (SPDSS) groundwater model for this area (CDM-Smith, December 6, 2006, Figure Sc). Modeling We used the Groundwater Vistas (GV) pre and post processor (version 6.85 Build 11, Rumbaugh, Environmental Solutions, Inc.) to construct and run a MODFLOW2000 (Harbaugh et al, 2000) model, and display the results. We exported processed cell -by -cell flow terms from the model into ArcView GIS software to process prepare report figures. The model area is 11,000 feet high (north to south) and 15,000 feet wide (west to east) centered on the Fair Meadows pit. The model consists of 55 rows and 75 columns using 200 foot square model cells.

We assigned MODFLOW "River" cell stage elevations using lOm DEM data, and interpolating in between. The western -most, up -gradient elevation was 4631 ft (msl) and the eastern -most down gradient elevation was 4605 ft (msl). The water level gradient from west to east is approximately 0.0017 ft/ft [(4631-4605)/15000)]. We modeled the aquifer's connection to the river using the MODFLOW "River" package which uses a streambed conductance term (COND) to calculated flow from one to the other in proportion to the hydraulic gradient of adjacent. A high level of connection mitigates impacts by allowing water to freely flow between the river and aquifer. Therefore, by using the lower end COND value that the data supports, our model creates more conservative (ie. more) modeled impacts. COND is calculated as the product of the streambed unit conductance (Ksb/m) times the wetted river area (length * width). Ksb is the streambed vertical permeability and m is the streambed thickness (m) which we assume is 1 ft so that Ksb/m equals Ksb. CDM-Smith (2006, Figure 9) evaluated the streambed permeability at three sites (SC -8, SC -13, and SC -14) within 10 miles of the FAIR MEADOWS pit, and came up with Ksb values ranging from 362 ft/day to 404 ft/day. We believe these rates are too high because they are too close to horizontal K (kh) values. Tests conducted in 2009 by Leonard Rice Engineers, Inc. (Denver, Co.) in Twn. 2N, Rng. 66W, Sec. 18, arrived at a Ksb value of 36 ft/day (Miller, 2009). We believe 36 ft/day is more accurate because it was determined through rigorous aquifer testing and is approximately 10 times less than the Kh value (300 ft/day in that area). A 10:1 Kh/Kv ratio is a common ratio used for alluvial aquifers. Therefore, to be conservative, we decided to reduce the connection to the river by using a Ksb of 36 ft/day. Using Google Earth imagery taken in September, 2021, we measured the river widths at the 4610, 4620, and 4630 ft elevation contour locations shown on Figure A2, which resulted in an average river width of 61 feet. Representative MODFLOW River cell parameters are shown in the table below. River Length (L) = 200 ft River Width (W) = 61 ft Streambed Conductance (Ksb/m) = 36 day -1 COND = 439,200 ft^2/day I Model Results We conducted two model runs to evaluate groundwater level changes caused by the Fair Meadows pit slurry wall. Pre -Fair Meadows Slurry Wall. Run The initial run <FMpit3> is meant to simulate the water table prior to slurry wall. Figure A8 shows the modeled water table contours compared to "target" contours shown in Figure A3.

This caused the water table to back up (ie. mound) behind the slurry walls as the modeled blue 4630 contour shows (convex east the down -gradient direction). The modeled (blue) 4620 ft and 4610 ft contours are slightly higher than what was observed (white contours) mostly because the observed contours are influenced by late season (September, 2022) irrigation pumping (ie. lower than average). Observed vs. Modeled Heads We compared the observed vs modeled heads at well locations in the figure below. 4670 4660 4650 4640 4630 4620 to 4610 a� 0 4 2 4600 4590 y = 1.0004x R2r- -0.304 4:014 • ••••- •.. • *ran • • • ` •• l• bw - •• • • •s • • • • • • • 4580 4580 4600 4620 4640 4660 4680 Observed Water Table Elevations (ft msl) Residual Mean Residual Standard Derr.

The best fit line shown above has a slope of 1.0004 : 1 which is a very close to perfect when considering all the data. However, observed levels are slightly higher than modeled up - gradient (>4620 ft) values, and observed values are slightly less than the modeled downgradient (<4620 ft) values. We did not spend a considerable time trying to obtain a better match heads because the ultimate objective to estimate potential mounding and shadowing is insensitive to aquifer parameters (discussed below in "Model Sensitivity" section). The "calibration" statistics are shown next to the figure above. The Root Mean Squared (RMS) error (9.64 ft) is the square of the difference between the observed and modeled values (aka "residual"). We feel this value is reasonable considering the data covers over approximately a 60 - year period and recent observations have been effected by pit dewatering, slurry walls and seasonal pumping and return flows. Mass Balance Table A4 shows the model mass balance results which shows the inflow and outflow components that include alluvial aquifer inflow and outflow and river leakages in and out of the Poudre River.

The Poudre river gains approximately 12.8 cfs (17.7- 4.9) within the model area. The mass balance error is 0.0% based on the difference between inflows and outflows. This indicates that the model has a high level of precision as well as accuracy as shown in the calibration statistics. Water Level Changes Caused by the Fair Meadows Slurry Wall In model run <FMpit4>, we turned off the model cells within the Fair Meadows pit to simulate the effect of the slurry wall. Figure A9 is the contoured "difference" in model output heads between the post -pit run minus pre -pit run determined using GIS grid -math techniques. Positive values on the north and west sides of the pit reflect mounding and negative values on the south and east side of the pit reflect lower water levels in the "shadow" of the pit. The maximum change in water level is approximately +2.5 ft in the northwest corner and slightly more than -1.5 ft of decline (shadowing) between the south side of the pit and the Poudre River. There are no registered production (non -monitoring) wells that are within the area where we predict over +1- 1 foot change. Well permit no. 28964 registered to Robert Davis is located in the northwest corner of the Mine property. According to J&T, Mr. Davis' property is now owned by the mine and they intend to abandon it. There are 16 registered wells that have reported water level depths (when drilled) to be less than 10 feet deep. Of these, only well permit 2020-F, belonging to the Summit Group of Southern Wisconsin, is within the zone of expected water level rise of between 0.5 and 1 ft. There are six registered wells that are currently being monitored by BAI that are within the area of expected mounding of 0.5 to 1.0 ft. None of these wells have measured water levels above 10 ft so no impact is expected. Well 374-WCB (Davis Farms) is the only other up -gradient well with an expected rise between 0.5 and 1.0 ft. The Davis well is reportedly 86 ft deep, with a measured water level of 31 ft when drilled. It reportedly can pump approximately 1200 gpm, one of the highest within the model area. The expected rise in water level will likely increase the yield in this well by increasing the saturated aquifer thickness and available drawdown. Considering that the seasonal water table fluctuates approximately 2-4 feet, and there are no registered wells located within the predicted water level change of +1- 1 ft, we believe the overall impact of the mine slurry wall will be insignificant. Model Sensitivity The modeled mound and "shadow" impacts are insensitive to the hydraulic conductivity (K) of the aquifer. An increase in K causes a proportional increase in model inflows, but also increases the hydraulic connection with the Poudre River which offsets any additional mounding or shadow effects. Therefore, we did not spend excessive time trying to match modeled verses observed heads by changing K values. The model results are very sensitive to the presence of surface water, but there is no realistic chance that the Poudre River is going away. Model results are also insensitive to streambed leakance. Even using a c onservatively low Ksb value of 36 ft/day, the Poudre River is large enough and the McGrane Water Engineering, LLC 1669 Apple Valley Rd. • Lyons, CO 80540 • Phone: (303) 917-1247 E -Mail: dennis@mcgranewater.com Web: ttp://www.mcgranewaterengineering.corn Fair Meadows Pit Groundwater Evaluation November 19, 2022 Page 10 of 28 aquifer is permeable enough to quickly respond to changes in groundwater levels caused by the slurry wall. Model Uncertainty There is uncertainty in our predictions related to measurement and modeling error. USGS 10m DEM Data was used to assign ground elevations to off -site wells. The overall accuracy of expressed as the root mean square error (RMSE) for 10m DEM data for one study in (Haneberg, 2006) is 1.87 m or approximately +1- 6 ft. The accuracy of surveyed site well elevations data is much higher, probably within a tenth of a foot, and the accuracy of hand -measured water levels can vary several inches. Our modeled predictions (Figure A9) include three types of error: 1) conceptual error (how the model is set up and what boundary conditions are used); 2) parametric error (how aquifer properties are measured and calculated); and 3) predictive error (which includes other influences such as seasonal recharge or climate change variations). It was beyond the scope of this project to quantitatively evaluate the sum of these errors. However, based on our professional opinion, we believe our results are reasonably accurate.

J&T Consulting, Inc. 305 Denver Avenue, Suite D Fort Lupton, CO 80621 Subject: Groundwater Monitoring Well Installation Mining Property Highway 263 Greeley, Colorado Project No. 22.3050 Dear Mr. York: CMT Technical Services - Colorado (CMTTS) performed drilling and groundwater monitoring well installation at the site of the proposed aggregate mine on Highway 263 in Greeley, Colorado. Figure 1 shows the location of the project site. Five borings were drilled on September 8, 9, and 12, 2022 using a truck mounted CME-55 drill rig equipped with 3-3/4 inch inside diameter hollow stem auger. A representative from CMTTS was onsite to log the borings and observe monitoring well installation. Figure 2 shows the project site with locations of the boring/monitoring wells. Subsurface conditions varied, but consisted of gravelly sands to sandy gravels, with localized layers of sandy clay. Claystone to sandstone bedrock was encountered in all five borings at depths ranging from 40 feet to 112 feet below ground surface. Groundwater was encountered in the five borings at depths ranging from 15 to 40 feet below ground surface. A PVC pipe monitoring well was constructed in each boring. The monitoring wells were constructed with 2 inch diameter PVC factory slotted and threaded pipe. Natural/native sands and gravels, 10/20 silica sand and bentonite chips were used at appropriate intervals as backfill material. The monitoring well riser pipe was completed at a height of approximately 2.5 to 3 feet above existing ground surface and protected with a steel stickup type monument embedded in a 2 by 2 foot concrete pad. A graphic log of the subsurface conditions encountered, locations of sampling, monitoring well construction details, and further explanation of the exploration are presented in the boring logs in Appendix A. Prior to its site visit, CMTTS filed the appropriate "Notice of Intent" form (GWS-51) with the Colorado Department of Water Resources (DWR). After completion of site services, CMTTS filed the appropriate "Well Construction Report" forms (GWS-31) with the DWR. The DWR acknowledged receipt of the GWS-31 forms. CMTTS also filed the well permit document (GWS-46) and paid the well permitting fees. The GWS-51, GWS-31 and GWS-46 forms are found in Appendix B.

Polis, Governor I Dan Gibbs, Executive Director I Kevin G. Rein, State Engineer/Director EXHIBIT H Wildlife Information The project area was surveyed for general wildlife habitat by Ecological Resource Consultants (ERC). The Screening Report for Federal and State Listed Threatened and Endangered Species from ERC is attached which describes the wildlife habitat present on the site and the common species that may be found in the habitat area. ERC conducted this screening for federal and state threatened, endangered and species of concern for the approximately 86 -acre survey area. The following provides key items identified as part of the report: 1. Two primary land use class/vegetation cover type exists within the survey area. Habitat within the survey area is characterized as Ruderal Crested Wheatgrass Grassland and Cropland Fallow Field. Historic land use for agricultural practices has led to degradation of the native vegetation community. 2. Generally, there are features on the survey area and the surrounding area that provide general habitat for local songbirds, raptors, and small to mid -size mammals. However, habitat within the survey area is somewhat degraded and of lower ecological value from a wildlife perspective due to historic and current land use for agriculture, which has restricted overall growth and establishment of vegetation. 3. Five (5) inactive non -raptor migratory birds and three (3) inactive non -eagle raptor nests were observed within the survey area. No eagle nests were observed within the survey area or the ¶6 mile surrounding buffer during the field inspection. No mapped CPW SAM protected areas were identified within the survey area. Any future land use changes that may occur within the survey area that remove vegetation during the active nesting season should first ensure that active nests are not disturbed. 4. No federally listed threatened and endangered species and/or habitat protected under the ESA were identified within the survey area. The survey area is not within designated critical habitat of any federally listed species. The vegetation community and features within the survey area were investigated as potential habitat for federally listed species. Any future land use changes will result in No Take on any federal listed species, their habitats, or proposed or designated critical habitat. 5. No State listed threatened or endangered species and/or habitat protected by CPW under Colorado Statute Title 33 were identified within the survey area. The vegetation communities within the survey area were investigated as potential habitat for state listed species. Any future land use changes will have no effect on any state listed species, their habitats, or proposed or designated critical habitat. The Screening Report for Federal and State Listed Threatened and Endangered Species prepared by Ecological Resource Consultants, Inc. includes the following recommendations regarding migratory birds and raptor nest sites in the survey area: a. Based- upon literature review and an onsite assessment of the survey area, ERC has determined that some migratory birds likely utilize the survey area. These birds, their eggs, and active nests are protected under the MBTA and take or possession of these resources is prohibited. Active nests must become inactive prior to destruction of the nest without a USFWS permit. Five (5) inactive non -raptor migratory bird nests were J tT Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application observed within the survey area. The nesting season in Colorado for non -raptor migratory birds occurs between April 1 and August 31 (CPW 2020). Seasonal MBTA non -raptor bird nesting activity status can vary seasonally and from year to year, therefore nesting surveys should be conducted no more than 7-10 days prior any future land use changes to ensure active nests are not disturbed during nesting season. b. Raptor (non -eagle) migratory bird nest sites are further protected by CPW guidelines. CPW has established recommended buffer zones and seasonal activity restrictions for a variety of Colorado raptors. Three (3) inactive raptor nests were observed and no CPW mapped raptor nest protection zones are located within the survey area (CPW 2022a). Inactive raptor nest sites have no regulatory restriction and do not require further agency coordination; however nest activity status can vary seasonally and from year-to-year. Future land use changes may require additional nest surveys (generally between February 1 and September 15 (CPW 2020)) to determine activity status within 1/2 to'/4 mile of the survey area to ensure compliance with CPW recommendations. c. Eagle nest sites are protected under Bald and Golden Eagle Act, further restricting destruction of any nest without a permit. No eagle nests sites were observed and no CPW nest sites eagle nests sites, communal roost sites, or winter roost sites are mapped on or within the vicinity of the survey area. Inactive eagle nest sites require further agency coordination even when nests are unoccupied as nest activity status can vary seasonally and from year-to-year. Future land use changes may require additional nest surveys (generally to be conducted between December 1 and July 31 (CPW 2020)) to determine activity status within 1/2 to '/4 mile of the survey area to ensure compliance with CPW recommendations.

(ERC) has prepared this report at the request of the property representative, J&T Consulting, Inc. The approximately 86.0 -acre property referred to herein as the Fairmeadows Site (survey area) is located in Greeley, Weld County, Colorado. The survey area is under consideration for potential future land use changes which will likely alter a majority of the current survey area landscape; therefore, this report has been prepared to specifically identify potential federal and state listed threatened and endangered species and/or habitat that could exist on or immediately surrounding the survey area. In addition, this report provides a cursory screening of general wildlife use characteristics and existing vegetation community types. This report has been prepared in accordance with the Migratory Bird Treaty Act (MBTA), Endangered Species Act (ESA) and Colorado Parks and Wildlife (CPW) Colorado Statute Title 33. GFM,M =.RAL_. CI....IRVFY .AREA. M ►FSCRIPTION The survey area is located approximately 0.13 miles east of the intersection of East 8th Street and Weld County Road 43 in Greeley, Weld County, Colorado in the Outlet Cache la Poudre River watershed (HUC 101900071008). More specifically, the survey area is located in Section 3, Township 5 North, Range 65 West, in Weld County (latitude 40.426512° north, longitude -104.652948° west). From the intersection of Interstate 25 and US -34, the survey area can be accessed by heading east on US -34 E for approximately 16.0 miles until reaching US -85 N. Turn on to US -85 N and continue for 2.3 miles until reaching East 8th Street. Take East 8th Street east for 1.2 mile until reaching the survey area to the northeast. The survey area is predominately upland agricultural land and home sites. Refer to Figure 1 and Figure 2 for a location map and a US Geological Survey (USGS) topographic map of the survey area. The survey area is situated within the Great Plains ecoregion (Bailey 1976) at an approximate elevation of 4,630 feet above mean sea level (AMSL). The survey area is comprised mainly of an agricultural field, previously disturbed ruderal herbaceous uplands, and home sites in the northern portion of the survey area. The vicinity of the survey area is comprised of agricultural land to the north, west, and east, and industrial development to the south. A dirt road follows the western, northern, and eastern boundary of the agricultural field and leads to the home sites in the northern portion of the survey area. A small patch of reed canarygrass (Phalaris arundinacea), occurs in a depression in the northwest corner of the survey area. The landscape within the survey area is predominantly characterized as the Ruderal Smooth Brome Grassland and Cropland Fallow Field ecological systems (NatureServe 2022). Ruderal Crested Wheatgrass Grassland The Ruderal Crested Wheatgrass Grassland occurs in a wide variety of human -disturbed habitats, including highway rights -of -way, jeep trails, etc. The type is also widely planted for revegetating disturbed land, pasture and hay fields, and has escaped into a variety of habitats, including prairie, riparian grasslands, and mesic mountain meadows (NatureServe 2022). This vegetation community across the survey area is dominated by non-native ruderal herbaceous species such as cheatgrass (Bromus tectorum), crested wheatgrass (Agropyron cristaum), and slender wheatgrass (Elymus trachycaulus), intermixed with a variety of other ruderal herbaceous species. Vegetative cover across this community generally comprises 25-65% of the ground cover. Cropland Fallow Field The Cropland Fallow Field community is broadly characterized as agricultural and developed vegetation. Agricultural vegetation includes a wide variety of growth forms, often with distinctive cultural forms (e.g., 1 Fairmeadows Site Threatened -Endangered Species and General Wildlife Screening orchards, vineyards, row crops, rice paddies) or structure (e.g., linear spacing, regular mowing, plowing), often to facilitate harvesting. "Agro-mesomorphic" tree, shrub, and herb growth forms are most typical. There is typically regular human management, such as plowing, mowing, or pruning that determines the structure and growth forms that are present. (NatureServe 2022). Within the survey area, this vegetation community is devoid of vegetative cover and has been recently tilled. 2 Fairmeadows Site Threatened -Endangered Species and General Wildlife Screening Legend Approximate Location Survey Area.

VEGETATION COMMUNITY AND WILDLIFE MAP FAIRMEADOWS SITE WELD COUNTY, COLORADO 4 375 750 (Feet 7 ERC Fairmeadows Site Threatened -Endangered Species and General Wildlife Screening 3.0 SCREENING METHODOLOGY ERC conducted a literature review as part of initial data collection for preparation of this report. ERC reviewed available literature sources including: CPW information and the US Fish and Wildlife Service (USFWS) Federal Register. A field inspection was subsequently conducted on September 14, 2022, to identify and document the presence of natural vegetation communities, general wildlife use and potential for threatened and endangered species/habitat. Upon review of all available resources, including literature and field inspections, ERC provides the following determination for the survey area. 4.0 GENERAL WILDLIFE HABITAT (NON -REGULATED) Wildlife utilizes the general landscape in a multitude of ways and uses a variety of habitats as areas of permanent inhabitance, seasonal inhabitance, breeding grounds, migratory routes, for foraging purposes, or as temporary shelter. Potential wildlife habitat includes the entire survey area. Historic and current land use associated with agricultural practices have restricted and/or degraded the development of any significant natural vegetation communities within a majority the survey area, which limits the overall quality of potential wildlife habitat. Two habitat types were observed within the survey area and are characterized by the Ruderal Crested Wheatgrass Grassland and Cropland Fallow Field communities which comprises the agricultural land and area around the home sites. These vegetation types comprise all of the vegetative cover and is dominated by non-native or weedy species is not typically considered of high ecological value to wildlife; however, agricultural lands can have beneficial values to certain wildlife species. These areas at a minimum are considered "open space" providing limited foraging and hunting grounds, refuge and limited areas for nesting (Kingery 1998). Such lands often serve as a buffer between natural areas, providing food, cover, nesting and open -space habitat which allow movement and exchange of plant and animal populations The pastureland which is present across the survey area has largely replaced the native shortgrass prairie habitat which would have been present in this region. Herbaceous non-native species and ruderal native species which permeate the vegetation community generally do not provide quality habitat for most wildlife. In general, although agriculture practices have altered the structure, function, community composition, and habitat value of land within a majority of the survey area, some areas do provide a variety of wildlife habitat values in an otherwise agricultural landscape. Within the survey area, significant limitations for wildlife use exist due to land use activities such as regular mowing, habitat fragmentation from fences, overgrazing, and noise disturbances from roadways and agricultural practices within the survey area and in areas adjacent to the survey area. Some other local wildlife species that may use this habitat within the survey area include coyote (Canis latrans), red fox (Vulpes vulpes), rabbit (Lepus sp.), cottontail (Sylvilagus sp.), black tailed prairie dog (Cynomys ludovicianus), white-tailed deer (Odocoileus virginianus), deer mouse (Peromyscus maniculatus), meadow vole (Microtus pennsylvanicus), red -winged blackbird (Agelaius phoeniceus), mourning dove (Zenaida macroura), killdeer (Charadrius vociferous), western meadowlark (Sturnella neglecta), barn owl (Tyto alba), hawks (Bute° sp.), and garter snake (Thamnophis sp.). These types of species may utilize the survey area; however, have not specifically been identified within the survey area. • Generally, there are features within the survey area and the surrounding area that provide general habitat for local songbirds, raptors, and small to mid -size mammals; however, the habitat within the survey area is characterized as Ruderal Crested Wheatgrass Grassland and Cropland Fallow Field, which are degraded from a wildlife perspective by historic and current land use practices. 8 Ak ERC Fairmeadows Site Threatened -Endangered Species and General Wildlife Screening 5.0 MIGRATORY BIRD TREATY ACT Migratory birds are protected under the Migratory Bird Treaty Act (MBTA) (16 U.S.C. 730-712). The MBTA makes it illegal for anyone to take, possess, import, export, transport, sell, purchase barter, or offer for sale, purchase, or barter any migratory bird, or the parts, nests, or eggs of such a bird except under the terms of a valid permit issued pursuant to Federal regulations. In Colorado, all birds except for the European starling (Sturnus vulgaris), house sparrow (Passer domesticus) and rock pigeon (Columba livia) are protected under the MBTA. A total of 523 migratory bird species are known to occur in the Mountain - Prairie Region (USFWS Region 6, Montana, Wyoming, Utah, North Dakota, South Dakota, Nebraska, Kansas and Colorado); 320 of the 523 migratory bird species are known to breed in USFWS Region 6. Migratory birds likely exist within the survey area. The vegetation communities in the survey area provide at the very least, potential nesting and foraging habitat for migratory birds. Northern flicker (Colaptes auratus), black -billed magpie (Pica hudsonious), mourning dove, Eurasian collared -dove (Streptopelia decaocto), and horned lark (Eremophila alpestris)were directly observed on the survey area during the field inspection. Such birds are protected under the MBTA and killing or possession of these birds (or their parts and nests) is prohibited under the MBTA. The migratory birds observed likely utilize the survey area primarily for foraging and limited seasonal nesting. • Based- upon literature review and an onsite assessment of the survey area, ERC has determined that some migratory birds likely utilize the survey area. These birds, their eggs, and active nests are protected under the MBTA and take or possession of these resources is prohibited. Active nests must become inactive prior to destruction of the nest without a USFWS permit. Five (5) inactive non -raptor migratory bird nests were observed within the survey area. The nesting season in Colorado for non - raptor migratory birds occurs between April 1 and August 31 (CPW 2020). Seasonal MBTA non -raptor bird nesting activity status can vary seasonally and from year to year, therefore nesting surveys should be conducted no more than 7-10 days prior any future land use changes to ensure active nests are not disturbed during nesting season. • Raptor (non -eagle) migratory bird nest sites are further protected by CPW guidelines. CPW has established recommended buffer zones and seasonal activity restrictions for a variety of Colorado raptors. Three (3) inactive raptor nests were observed and no CPW mapped raptor nest protection zones are located within the survey area (CPW 2022a). Inactive raptor nest sites have no regulatory restriction and do not require further agency coordination; however nest activity status can vary seasonally and from year-to-year. Future land use changes may require additional nest surveys (generally between February 1 and September 15 (CPW 2020)) to determine activity status within %2 to % mile of the survey area to ensure compliance with CPW recommendations. • Eagle nest sites are protected under Bald and Golden Eagle Act, further restricting destruction of any nest without a permit. No eagle nests sites were observed and no CPW nest sites eagle nests sites, communal roost sites, or winter roost sites are mapped on or within the vicinity of the survey area. Inactive eagle nest sites require further agency coordination even when nests are unoccupied as nest activity status can vary seasonally and from year-to-year. Future land use changes may require additional nest surveys (generally to be conducted between December 1 and July 31 (CPW 2020)) to determine activity status within 1/2 to % mile of the survey area to ensure compliance with CPW recommendations. 9 A ERC Fairmeadows Site Threatened -Endangered Species and General Wildlife Screening 6.0 SPECIES PROTECTED UNDER THE ENDANGERED SPECIES ACT OF 1973 The ESA of 1973 was enacted by the United States to conserve endangered and threatened species and the ecosystems that they depend on. Under the ESA, species may be listed as either "endangered" or "threatened"; both designations are protected by law. The ESA is administered by the USFWS. The USFWS has developed project specific species lists, available online by request, identifying threatened, endangered, and proposed species, designated critical habitat, and candidate species protected under the ESA that may occur within the boundary of a proposed project and/or may be affected by a proposed project (USFWS 2022) (Project Code: 2022-0088046). The species list for the survey area has identified potential for a total of 8 threatened or endangered species within the survey area. Species Not Present The following federally listed threatened and endangered species are identified to occur within Weld County. However, these species are not known to exist within the specific vicinity of the survey area and/or have specific habitat requirements (i.e., elevation range) that are not common in the vicinity of the survey area. Common Name Scientific Name Status* Determination Gray Wolf Canis lupus FE NO TAKE *Status key: FT— Federally listed as threatened • The survey area does not contain the specific habitat characteristics necessary to support this species listed above. This species and/or critical habitat is not present within the survey area. Therefore, future land use will result in No Take of the species, their habitats, or proposed or designated critical habitat. Water Depletions Species The USFWS under the ESA has determined that water depletions in the South Platte River Basin are considered an adverse effect to the listed species identified below. The survey area is considered to be located within the South Platte River Basin. Common Name Scientific Name Status* Determination Pallid sturgeon Scaphirhycchus albus FE NOT PRESENT, NO TAKE^ Piping plover Charadrius melodus FT NOT PRESENT, NO TAKE ^ Western prairie fringed orchid Platanthera praeclara FT NOT PRESENT, NO TAKE^ Whooping crane Grus Americana FE NOT PRESENT, NO TAKE^ *Status key: FT— Federally listed as threatened FE — Federally listed as endangered ^The project is assumed to be mixed -use commercial and residential development supplied by existing municipal water supply; therefore, the project would not be considered a water depletion. Any water related project conducted in the Platte River Basin that has a federal nexus; such as federal funding or a federal permit (i.e., Clean Water Act (CWA) Section 404 Permit), is subject to ESA Section 7 Consultation with the USFWS. The consultation is a mandate for water depletion projects that may affect threatened and endangered species that rely on the South Platte River. 10 Fairmeadows Site Threatened -Endangered Species and General Wildlife Screening • The survey area does not contain the specific habitat characteristics necessary to support the species listed above. These species and/or critical habitat is not present within the survey area. It is assumed herein that future land use changes would not be considered a new water depletion. Therefore, the project would result in No Take to these species. Species Potentially within Range The following federally listed threatened and endangered species are identified to occur or historically occur within Weld County (USFWS 2022). The survey area is located within the potential known range for these species to occur. Further analysis was conducted to determine if the species or habitat has the potential to exist within the survey area considering site -specific conditions and characteristics. A brief explanation is provided as to the species life cycle, habitat requirements and potential occurrence within the survey area. The survey area is not within designated critical habitat of any federally listed species. Common Name Scientific Name Status* Determination Eastern Black rail Laterallus jamaicensis ssp. jamaicensis FT NO TAKE Preble's meadow jumping mouse Zapus hudsonius preblei FT NO TAKE Ute Ladies' -tresses orchid Spiranthes diluvialis FT NO TAKE *Status key: FT— Federally listed as threatened EASTERN BLACK RAIL (LATERALLUS JAMAICENSIS SSP. JAMAICENSIS) Eastern black rail (rail) is a member of the family Rallidae that includes rails, coots, and gallinules. It is one of five recognized subspecies of black rail, two of which, L. j. jamaicensis and L. j. coturniculus, are found in North America, but do not co-occur (Clements et al 2021). On November 9, 2020, the US Fish and Wildlife Service issued a final rule to list the rail as a federally threatened species under the ESA. The rail are gray -black in coloration, with white speckled upperparts, and has a grayish crown, a chestnut -colored nape of the neck, and a short tail. Within the interior United States, rail are reliably located within the Arkansas River Valley of Colorado and the northern portion of the Front Range. Rail require dense vegetative cover that allows movement underneath the canopy. Because these birds are found in a variety of salt, brackish, and freshwater marsh habitats that can be tidally or non -tidally influenced, plant structure is considered more important than plant species composition in predicting habitat suitability (Flores and Eddleman 1995). Vegetation height is generally less than or equal to 1 meter in coastal habitats, but taller in occupied cattail and bulrush marshes (Davidson 1992). A 2019 species status assessment noted that when shrub densities become too high, the habitat becomes less suitable for eastern black rails. Soils are moist to saturated, occasionally dry, and interspersed with, or adjacent to, very shallow water of 1 to 6 centimeters, (Legare and Eddleman 2001). In Colorado, eastern black rails use habitat with shallow wetlands dominated by cattails (Typha spp.), hardstem bulrush (Scirpus acutus var. acutus) and soft -stemmed bulrush (Schoenoplectus tabernaemontani), with willow (Salix spp.) in the overstory (Griese 1980). Nests are constructed of live and dead emergent, herbaceous plants, like fine grasses, rushes or sedges, often with a dense clump of vegetation that conceals the nest from above. These nests may be dome shaped and have a ramp of dead vegetation on one side (Harlow 1913) (Todd 1977). • Rail are known to occur in herbaceous riparian areas in Weld County. The soils in and around the depression with the small patch of reed canarygrass are dry and devoid of an adjacent water source. Due to the absence of suitable riparian habitat, it is unlikely that the rail exists within the survey area. Any future land use changes on the survey area would result in No Take of this species or potential habitat of this species. 11 Fairmeadows Site Threatened -Endangered Species and General Wildlife Screening PREBLE'S MEADOW JUMPING MOUSE (ZAPUS HUDSONIUS PREBLEI) On May 13, 1998 the US Fish and Wildlife Service issued a final rule to list the Preble's meadow jumping mouse (PMJM) as a federally threatened species under the ESA. PMJM range extends from southwestern Wyoming through eastern Colorado generally below 7,600 feet. Armstrong et al. (1997) described typical PMJM habitats as "well -developed plains riparian vegetation with relatively undisturbed grassland and a water source in close proximity." Also noted was a preference for "dense herbaceous vegetation consisting of a variety of grasses, forbs and thick shrubs" (USFWS 1999). This species is known to regularly travel into adjacent uplands to feed and hibernate. The PMJM hibernates in an underground burrow from September to May. PMJM bears two to three litters per year, averaging five young per litter, in a grass - lined nest. In general, PMJM surveys are recommended for areas with suitable habitat in Weld County below 7,600 feet and within 300 feet of vegetated irrigation canals, ditches, and wetlands. Areas that are highly disturbed or modified (including landscaped lots and paved areas) or wetland areas dominated by cattails are excluded from this recommendation. • PMJM is known to occur in riparian habitat within Weld County (ERO Resources 2006). The survey area and immediate vicinity is not designated as Critical Mouse Habitat by the USFWS (CPW 2014). The USFWS Mouse Block Clearance Map for the Denver Metro Area (ERO 2010) which identifies areas exempt from further review for PMJM habitat, shows the survey area does not occur within the Block Clearance Zone. • Vegetation communities in the survey area are not typical habitat for the PMJM consisting primarily of herbaceous cover and lack well -developed shrub and tree cover. Due to the absence of suitable riparian habitat, it is unlikely that the PMJM exists within the survey. Any future land use changes on the survey area would result in No Take of this species or potential habitat of this species. UTE LADIES' -TRESSES (SPIRANTHES DILUVIALIS) The Ute ladies' -tresses (ULT) is listed as federally threatened under the ESA. The ULT occurs in seasonally moist soils and wet meadows near springs, lakes, or perennial streams and their associated floodplains below 6,500 feet in elevation in certain areas of Utah, Colorado, Idaho, Wyoming, and Nevada. Typical sites include early successional riparian habitats such as point bars, sand bars, and low lying gravelly, sandy, or cobbly edges. They seem to require "permanent subirrigation", conditions where the water table is close to the surface, but they are not tolerant of permanent standing water. Typical habitat is open and sparsely vegetated, populations decline if trees and shrubs invade the habitat. They do not compete well with aggressive species such as reed canary grass or monocultures of cattails. • There are known population occurrences of ULT in Weld County. A total of 21 historic and extant populations have been recorded in Colorado in 6 watersheds, none of which have occurred in the Outlet Cache la Poudre River Watershed. The USFWS ULT Block Clearance Zone for the Denver Metro Area (USFWS 2008) which identifies areas exempt from further review for ULT habitat, shows the survey area does not occur within the Block Clearance Zone. • The upland agricultural land within the survey area are not typical habitat conducive to the Ute ladies' - tresses. No Ute ladies' -tresses or suitable habitat was identified within the survey area. Any future land use changes on the survey area would result in No Take of this species or potential habitat of this species. 12 ERC Fairmeadows Site Threatened -Endangered Species and General Wildlife Screening 7.0 STATE THREATENED AND ENDANGERED SPECIES Species identified as state threatened or endangered are protected by the CPW under Colorado Statute Title 33. State regulations prohibit "any person to take, possess, transport, export, process, sell or offer for sale, or ship and for any common or contract carrier to knowingly transport or receive for shipment" any species or subspecies listed as state endangered or threatened. The CPW also has identified State Species of Special Concern, which are species or subspecies of native wildlife that are currently vulnerable in their Colorado range and have the potential to become threatened or endangered. Species of Special Concern are not protected under State regulations but the `take' of individuals and disturbance of their habitat is strongly discouraged. All state listed species were screened as potential inhabitants of the survey area based on general habitat requirements and CPW Species Profiles (CPW 2022b). ERC evaluated the species listed by CPW as threatened or endangered that could potentially exist within the survey area. All animal species listed above as threatened or endangered by the USFWS are also listed by the CPW as threatened or endangered, respectively, therefore were not duplicated below. Species Not Present The following listed threatened and endangered species are identified to occur within the state (CPW 2022b). However, these species are not known to exist within the specific vicinity of the survey area and/or have specific habitat requirements (i.e., elevation range) that are not common in the vicinity of the survey area (CPW 2020b and USFWS 2020).

These species and/or critical habitat is not present within the survey area. Therefore, any future land use changes will have no effect on the species, their habitats, or proposed or designated critical habitat. Species Potentially within Range The following state listed threatened and endangered species are identified to occur or historically occur within Weld County. The survey area is located within the potential known range for these species. Further analysis was conducted to determine if the species or habitat has the potential to exist on the survey area considering site -specific conditions and characteristics. A brief explanation is provided as to the species life cycle, habitat requirements and potential occurrence within the survey area. Common Name Scientific Name Status* Black -footed ferret Mustela nigripes SE *Status key: ST - State listed as threatened SE — State listed as endangered BLACK -FOOTED FERRET (MUSTELA NIGRIPES) The black -footed ferret (BFF) (Mustela nigripes) is a medium-sized mustelid (a member of the weasel family). The BFF is the only ferret species native to the Americas. Its historical range spanned much of western North America's intermountain and prairie grasslands, extending from Canada to Mexico. Historically, BFF habitat coincided with habitats of black -tailed prairie dog (C. ludovicianus), Gunnison's prairie dog (C. gunnisoni), and white-tailed prairie dog (C. leucurus). Prairie dogs make up more than 90% of the BFF's diet. BFF's are limited to open habitat, the same habitat used by prairie dogs: grasslands, steppe, and shrub steppe. It depends largely on prairie dogs: ferrets prey on prairie dogs and utilize their burrows for shelter and denning (Hillman and Clark, 1980). It has been estimated that about 40-60 hectares of prairie dog colony are needed to support one ferret (Belant and Biggins 2008). BFF's once numbered in the tens of thousands, but due to a combination of human -induced threats they were believed to be extinct twice in the 20th century. As of 2015, BFFs have been reintroduced in the wild at 24 sites across 8 states, Canada, and Mexico. • No BFF individuals were observed on or surrounding the survey area. The survey area is located within the overall range of the black -tailed prairie dog; however, no colonies were observed within the survey area. Further, the survey area occurs within the block clearance zone for black -footed ferret surveys (USFWS 2009). Any future land use changes within the survey area should have no effect on the continued existence or potential habitat of this species. 8.0 SUMMARY ERC has conducted this screening for federal and state listed threatened and endangered species and general wildlife for the approximately 86.0 -acre survey area. The following summarizes key items identified as part of this report: 1. Two primary land use class/vegetation cover type exists within the survey area. Habitat within the survey area is characterized as Ruderal Crested Wheatgrass Grassland and Cropland Fallow Field. Historic land use for agricultural practices has led to degradation of the native vegetation community. 14 Fairmeadows Site Threatened -Endangered Species and General Wildlife Screening 2. Generally, there are features on the survey area and the surrounding area that provide general habitat for local songbirds, raptors, and small to mid -size mammals. However, habitat within the survey area is somewhat degraded and of lower ecological value from a wildlife perspective due to historic and current land use for agriculture, which has restricted overall growth and establishment of vegetation. 3. Five (5) inactive non -raptor migratory birds and three (3) inactive non -eagle raptor nests were observed within the survey area. No eagle nests were observed within the survey area or the %2 mile surrounding buffer during the field inspection. No mapped CPW SAM protected areas were identified within the survey area. Any future land use changes that may occur within the survey area that remove vegetation during the active nesting season should first ensure that active nests are not disturbed. 4. No federally listed threatened and endangered species and/or habitat protected under the ESA were identified within the survey area. The survey area is not within designated critical habitat of any federally listed species. The vegetation community and features within the survey area were investigated as potential habitat for federally listed species. Any future land use changes will result in No Take on any federal listed species, their habitats, or proposed or designated critical habitat. 5. No State listed threatened or endangered species and/or habitat protected by CPW under Colorado Statute Title 33 were identified within the survey area. The vegetation communities within the survey area were investigated as potential habitat for state listed species. Any future land use changes will have no effect on any state listed species, their habitats, or proposed or designated critical habitat.

Warning: Soil Map may not be valid at this scale. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for map measurements. Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

The map unit descriptions in this report, along with the maps, provide information on the composition of map units and properties of their components. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. The Map Unit Description (Brief, Generated) report displays a generated description of the major soils that occur in a map unit. Descriptions of non -soil (miscellaneous areas) and minor map unit components are not included. This description is generated from the underlying soil attribute data. Additional information about the map units described in this report is available in other Soil Data Mart reports, which give properties of the soils and the limitations, capabilities, and potentials for many uses. Also, the narratives that accompany the Soil Data Mart reports define some of the properties included in the map unit descriptions.

We received a request for an Approved Jurisdictional Determination (JD) for the above project area. The project area has been reviewed in accordance with Section 404 of the Clean Water Act under which the U.S. Army Corps of Engineers regulates the discharge of dredged and fill material, and any excavation activity associated with a dredge and fill project in waters of the United States. At your request, a JD has been prepared for the subject area. Based on a review of available documentation, we have determined that the resources labeled Ditch 1 on the attached Figure 1: Project Area Features is not a water of the United States. The attached JD form provides rationale for why no resources on the property meet the definition of waters of the United States. Therefore, a Department of the Army permit is not required for the discharge of fill material into this site under Section 404. The JD is attached to this letter. If you are not in agreement with the JD decision, you may request an administrative appeal under regulation 33 CFR 331, by using the attached Appeal Form and Administrative Appeal Process form. The request for appeal must be received within 60 days from the date of this letter. It is not necessary to submit a Request for Appeal if you do not object to the JD. This JD is valid for a period of five years from the date of this letter, unless new information warrants revisions of the JDs before the expiration date, or unless the Corps has identified, after a possible public notice and comment, that specific geographic areas with rapidly changing environmental conditions merit re -verification on a more frequent basis.

Identify (estimate) size of waters of the U.S. in the review area: Non -wetland waters: linear feet: Wetlands: c. Limits (boundaries) of jurisdiction based on: Elevation of established OHWM (if known): 2. Non -regulated waters/wetlands (check if applicable):3 1 Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). 3 Supporting documentation is presented in Section III.F. Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: Ditch 1. See reference below in Section III.F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below. 1.

Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break. ibid. 3 Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.).

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: 2.

ERC Project #420-2204 � ERC Fairmeadows Site Aquatic Resource Delineation Report EXECUTIVE SUMMARY This report summarizes the delineation of aquatic resources completed by Ecological Resource Consultants, Inc. (ERC) for the Fairmeadows site (survey area). ERC conducted a formal routine onsite delineation of aquatic resources within the approximately 86.0 -acre survey area located in the City of Greeley, Weld County, Colorado on September 14, 2022. No aquatic resources were identified within the survey area. A small depression in the northwest corner of the survey area was vegetated with hydrophytic species but lacked hydric soil or hydrology indicators. The USGS topographic map depicts an intermittent stream and wetlands in the southeastern portion of the survey area. This area was investigated during the site visit and was determined to be comprised of a dry, upland agricultural field. All areas that have been investigated in the field are mapped on the enclosed Aquatic Resource Delineation Map (Appendix A).

(ERC) for the Fairmeadows Site (survey area). The purpose of this report is to provide a formal delineation of aquatic resources within the approximately 86.0 -acre survey area established for this site. This report documents aquatic resource boundaries for verification and jurisdictional review by the US Army Corps of Engineers (USACE). 2.0 LOCATION The survey area is located approximately 0.13 miles east of the intersection of East 8th Street and Weld County Road 43 in Greeley, Weld County, Colorado in the Outlet Cache la Poudre River watershed (HUC 101900071008). More specifically, the survey area is located in Section 3, Township 5 North, Range 65 West, in Weld County (latitude 40.426512° north, longitude -104.652948° west). From the intersection of Interstate 25 and US -34, the survey area can be accessed by heading east on US -34 E for approximately 16.0 miles until reaching US -85 N. Turn on to US -85 N and continue for 2.3 miles until reaching East 8th Street. Take East 8th Street east for 1.2 mile until reaching the survey area to the northeast. The survey area is predominately upland agricultural land and home sites. Refer to Figure 1 and Figure 2 for a location map and a US Geological Survey (USGS) topographic map of the survey area. 1 Legend t Fort Collins 1 weiey ti S Approximate Location Survey Area , N eft a I Prepared By: se\ ERC 2820 Wilderness Place Suite A Boulder, CO 80301 (303) 679-4820 ERC #420-2204 FIGURE 1.

During the field inspection, dominant vegetation was recorded, representative hydrologic indicators were noted, and soil samples were examined for hydric indicators. Delineation field work for the survey area was completed on September 14, 2022. The weather during the delineation was sunny and windy at approximately 80 degrees Fahrenheit. At the time of the field evaluation, the conditions observed within the survey area were typical for the region and sufficient indicators of vegetation, soils and hydrology were observed to make a wetland determination. The USACE and the Environmental Protection Agency (USEPA) jointly define wetlands as: "those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" [40 CFR 230.3(t)]. Three general environmental parameters define a wetland. These parameters must include the presence of hydrophytic vegetation, hydric soils, and wetland hydrology. Except under certain situations, evidence of a minimum of one positive wetland indicator from each of the above parameters must be identified in order to make a positive wetland determination. In addition, waters of the U.S. are also defined as areas that "include essentially all surface waters such as rivers, streams and their tributaries, all wetlands adjacent to these waters, and all ponds, lakes and reservoirs". The boundaries of some waters of the U.S. (i.e., such as streams or lakes) are further defined by the ordinary high water mark (OHWM). The OHWM is characterized as "the line on the shores established by the fluctuations of water and indicated by physical characteristics such as: a clear natural line impressed on the bank, shelving, changes in the character of the soil, wetland vegetation, the presence of litter and debris, and other appropriate means that consider the characteristics of the surrounding areas" (USACE 2005). Areas that do not meet any one of the wetland parameters (hydrophytic vegetation, hydric soils and/or wetland hydrology) or non -vegetated stream channel/open water (OHWM) were classified as a non -wetland (upland) and mapped as such. Each wetland determination point was recorded using a hand-held Trimble GeoXH global positioning system (GPS) receiver. The resulting GPS data were post processed using GPS Pathfinder Office 5.85 software. Post processing differential correction provided an average horizontal mapping accuracy of +/- 2 feet. Post -processed GPS data were imported into ArcMap Geographic Information Systems (GIS) (Version 10.6) for spatial analysis and mapping. Any aquatic resources delineated within the survey area are depicted on the Aquatic Resource Delineation Maps are provided as Appendix A. Wetland Determination data sheets are provided in Appendix B. 4 A ERC Fairmeadows Site Aquatic Resource Delineation Report 4.0 EXISTING CONDITIONS 4.1 LANDSCAPE SETTING The survey area is situated within the Great Plains ecoregion (Bailey 1976) at an approximate elevation of 4,630 feet above mean sea level (AMSL). The survey area is comprised mainly of an agricultural field, previously disturbed ruderal herbaceous uplands, and home sites in the northern portion of the survey area. The vicinity of the survey area is comprised of agricultural land to the north, west, and east, and industrial development to the south. A dirt road follows the western, northern, and eastern boundary of the agricultural field and leads to the home sites in the northern portion of the survey area. The landscape within the survey area is predominantly characterized as the Ruderal Smooth Brome Grassland and Cropland Fallow Field ecological systems (NatureServe 2022). The Ruderal Crested Wheatgrass Grassland occurs in a wide variety of human -disturbed habitats, including highway rights -of -way, jeep trails, etc. The type is also widely planted for revegetating disturbed land, pasture and hay fields, and has escaped into a variety of habitats, including prairie, riparian grasslands, and mesic mountain meadows (NatureServe 2022). The Cropland Fallow Field community is broadly characterized as agricultural and developed vegetation. Agricultural vegetation includes a wide variety of growth forms, often with distinctive cultural forms (e.g., orchards, vineyards, row crops, rice paddies) or structure (e.g., linear spacing, regular mowing, plowing), often to facilitate harvesting. "Agro-mesomorphic" tree, shrub, and herb growth forms are most typical. There is typically regular human management, such as plowing, mowing, or pruning that determines the structure and growth forms that are present. (NatureServe 2022). 4.2 AQUATIC RESOURCES No aquatic resources were delineated by ERC within the survey area. Six wetland determination data points were taken within the survey area to verify the lack of any aquatic resource habitat. A small area within a depression in the northwestern portion of the survey area contained a dominance of hydrophytic vegetation (reed canarygrass (Phalaris arundinacea)) but lacked indicators for hydrology or hydric soils (data point DP -U6 in Appendices A and B). The USDA Web -Soil Survey mapping identifies the soils within the survey area as Aquolls and Aquents gravelly substratum, Ellicott -Ellicott sandy -skeletal complex, Dacono clay loam, and Ustic Torriorthents moderately steep (NRCS 2022). Of the mapped soils, Aquolls and Aquents gravelly substratum is listed as hydric soils on the USDA NRCS Soil Data Access Hydric Soils List (NRCS 2022). Refer to Table 2 for a list of vegetation identified within the survey area (Lichvar et al. 2016). The Aquatic Resource Delineation Map is provided as Appendix A.

Topography across the survey area is gently sloping to the southern boundary of the survey area. Uplands within the survey area are predominantly characterized by the Ruderal Crested Wheatgrass Grassland and Cropland Fallow Field communities (NatureServe 2022). The Ruderal Crested Wheatgrass vegetation community characterized within the survey area is somewhat based on natural vegetation associations in the region; however, have been disturbed by historic and current land use practices thus represent somewhat degraded forms of these communities. A summary of upland habitat within the survey area is provided as follows. Ruderal Crested Wheatgrass Grassland Community The Ruderal Crested Wheatgrass Grassland community within the survey area includes lands within the survey area that can generally be described as open space with exotic grasses dominating the vegetated areas including the areas around the home sites. These areas are generally dominated by herbaceous species such as crested wheatgrass (Agropyron cristatum), kochia (Bassia scoparium), and sand dropseed (Sporobolus cryptandrus). Cropland Fallow Field Community The Cropland Fallow Field community within the survey area includes lands within the survey area that can generally be described as a fallow agricultural field within an unvegetated area. These areas appear to currently be in agricultural use as it has been recently tilled and have sparse -to -no vegetive cover.

J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application EXHIBIT L Reclamation Cost A phased and cumulative bonding approach is proposed for the Sunset Industrial Pit mining site operation. The financial warranty required for each phase is the warranty required to completely reclaim that phase. The financial warranty required for each phase of mining includes a cost component for the slurry wall liner required to close the current mined area should project be stopped and the operator defaulted. Because the slurry wall liner required to close the current mined area for each phase of mining is replaced with a new slurry wall liner required to close the current mined area component as the next phase of mining occurs, the financial warranty required for this component for the previous phase is credited back in each phase's required financial warranty calculation. This accurately calculates the additional financial warranty required for any given phase of mining and for the current limit of disturbance as well as accounting for the financial warranty that has already been posted to ensure that the Division has sufficient cumulative financial warranty to complete the reclamation. Direct costs related to the construction of the reclamation components that have been included in the financial warranty calculations include: Scarifying disturbed ground surfaces, re -applying topsoil over disturbed areas, revegetating disturbed areas, dewatering the full pit, slurry wall liner construction, and contractor mobilization. The slurry wall liner construction costs have been broken down further to include costs for different depths to bedrock as provided from the DRMS on previous 112 applications. Overhead, profit, and project management costs were then calculated and added to the direct construction costs to arrive at the required financial warranty for each phase. As each new phase is started, the financial warranty for that phase will be posted with the Division. When a phase has been reclaimed, inspected, and accepted by the Division, the associated financial warranty for that phase can then be reduced/released to 20% of the financial warranty required for that phase. Please see the attached calculations for details of the costs and quantities used to determine the financial warranty required for each phase of mining. The following table summarizes the financial warranty required for each phase, and the cumulative financial warranty that will be provided during any given phase.

Water and Sewer Pipelines J-2 Contracting Company believes that the mining operation, as proposed, will not adversely affect any of the permanent, man-made structures located within 200 ft of the affected area. However, the applicant still anticipates providing evidence of agreements for compensation with the appropriate structure owners or an engineering evaluation (see attached slope stability report) that adequately demonstrates that the proposed mining and reclamation operations will not result in damage to the structures. There are oil/gas wells and processing equipment located on the site or within 200 feet of the permit boundary.

J-2 Contracting Company — Sunset Industrial Pit Slope Stability Analysis Page ii INTRODUCTION J-2 Contracting Company proposes to mine the property located in the west half of Section 3, Township 5 North, Range 65 West of the 6th Principal Meridian, in Weld County, Colorado. The property is bounded by the private property on the west, the Greeley -Weld County Airport on the north and east, private property on the east, and East 8th Street on the south. The proposed mining operation will extract gravel reserves from locations adjacent to man-made structures. The rules and regulations of the Division of Reclamation, Mining, and Safety (DRMS) require that any mining within a 200 -foot setback of a man-made structure show thorough engineering analysis that the proposed mining will not cause damage to the structure. The accepted method of demonstrating this is through a slope stability analysis. This report contains an overview of the methodology used in the analysis of the mining slopes and their estimated affects on all man-made structures. Recommendations regarding acceptable setbacks from man-made structures have also been included. OVERVIEW The DRMS mining plan proposes that the property will be mined in 2 pits, and reclaimed as a water storage reservoir. The mining will occur at 3H:1V slopes. A bench will be constructed during mining to allow a slurry wall to be installed around the perimeter of each pit. Clay soils will be placed above the bench to complete the reclamation of the site. The reservoir (including both cells) will cover an estimated 54 surface acres when full. The actual surface area of the cells will depend on the final configuration of the reservoir after reclamation is complete. GEOTECHNICAL DATA Exploratory borings and monitoring wells were done on the site by Drilling Engineers. Logs of the borings and monitoring well used to estimate the soil types and thicknesses for this study are included in Appendix D. J&T Consulting, Inc. (JT) estimated soil strength parameters based on the information from the boring and monitor well logs and other stability analyses that have been performed on gravel mining operations along the Front Range. Table 1, on the following page, represents a summary of the soil strength parameters that were used in this stability analysis.

Galena was designed to analyze the slope stability of earth embankments subjected to several critical situations that may occur during the life of the embankment. For this project, eleven cases were identified as critical during the mining operation. Static and pseudo -static conditions were analyzed in each case. Pseudo -static peak acceleration factors (peak horizontal acceleration, or PHA) were taken from USGS information for the western United States. The 2% probability of exceedance in 50 years (the most conservative) was used. The USGS peak acceleration map is included in Appendix E. A peak acceleration factor of 0.10 x gravity was taken from this data. A conservative earthquake loading coefficient of 0.50 x PHA is often used for slope stability analyses (50% of PHA). We used an even more conservative approach and used 70% of the PHA for this area for our earthquake loading coefficient. Hence, 0.70 x 0.10 = 0.07. All mining side slopes will be 3H:1 V. Six cases were analyzed where the mining is adjacent to man-made structures. The locations of the cases are shown on the case location map included in Appendix A. Case 1 — Fence West of Pit. The mining operation is adjacent to a fence near the west property line of the site. The proposed setback for mining is 20 feet from the fence. The mining depth was assumed to be 90 feet in this area based on bore log information. Case 2 — Fence North of Pit. The mining operation is adjacent to a fence near the north property line of the site. The proposed setback for mining is 11 feet from the fence. The mining depth was assumed to be 108 feet in this area based on bore log information. UT Consulting, Inc. J-2 Contracting Company — Sunset Industrial Pit Slope Stability Analysis Page 2 Case 3 — Fence East of Pit. The mining operation is adjacent to a fence near the east property line of the site. The proposed setback for mining is 50 feet from the fence. The mining depth was assumed to be 112 feet in this area based on bore log information. Case 4 — Fence and Lift Station South of Pit. The mining operation is adjacent to a fence and lift station south of the pit. The proposed setback for mining is 40 feet from the fence and lift station. The mining depth was assumed to be 81 feet in this area based on bore log information. Case 5 — Sanitary Sewer, Water Line, Fence, Fiber Line, Roadway, Bridge/Ditch, Structure, Power Poles and Lines, and Building South of Pit. The mining operation is adjacent to sanitary sewer, water line, fence, fiber line, roadway, bridge/ditch, structure, power poles and lines, and building adjacent to the south side of the pit. The proposed setback for mining is 28 feet from the sanitary sewer, the closest structure. The mining depth was assumed to be 79 feet in this area based on bore log information. Case 6 — Water Line, Power Poles and Lines, Fence, Telephone Line, and Oil/Gas Equipment West of Pit. The mining operation is adjacent water line, power poles and lines, fence, telephone line, and oil/gas equipment adjacent to the west side of the pit. The proposed setback for mining is 31 feet from the water line, the closest structure. The mining depth was assumed to be 51 feet in this area based on bore log. The cross -sections located in Appendix B show the estimated phreatic surface associated with each case, the geometry used in the mining, and the locations of the man-made structures adjacent to the mining slopes. METHODOLOGY The mining embankment configuration shown in the computer analysis represents the estimated conditions for this site. If mining conditions differ from the estimated conditions, the slope stability will need to be re-evaluated on a case -by -case basis. The Bishop Method was used in the computer analysis for determining safety factors. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 20,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the policy of the Mined Land Reclamation Board (MLRD) for Factors of Safety for Slope Stability / Geotechnical Analyses. .J&T Consulting, Inc. J-2 Contracting Company — Sunset Industrial Pit Slope Stability Analysis Page 3 SLOPE STABILITY RESULTS The MLRB requires minimum safety factors of 1.50 for static condition analyses and 1.30 for pseudo -static (earthquake loading) condition analyses for embankments adjacent to critical structures. The calculated factors of safety are within the design criteria specified for this project and can be considered indicators of the mining slope performance under the various conditions. The slopes were analyzed using full and empty reservoir conditions. The results of the static condition and pseudo -static condition slope stability analyses are shown in Table 2 and Table 3.

J-2 Contracting Company — Sunset Industrial Pit Slope Stability Analysis Page 6 The following recommendations for monitoring of slope stability should be followed: 1. A visual inspection of the excavated slopes should be done on a weekly basis for the duration of mining. This inspection should consist of walking the existing ground and looking for any signs of stress cracks or other potential signs of slope failure. Some minor sloughing of slopes is expected on any mine site. The intent of this inspection is to locate potential major slope failures that could potentially extend back into a structure. 2 A visual inspection should be done after a major precipitation event that has saturated the ground using the same procedures. A major precipitation event would be defined as a storm that produces an intensity level reached once in 50 years on the average. 3 If a visual inspection detects signs of a potential slope failure, qualified personnel should be contacted to evaluate and recommend remediation work to stabilize the area. 4 If no visible signs of slope failure are detected during mining, then the inspection period could be reduced to once per 6 months after mining completion, or after every major precipitation event.

York J&T Consulting, Inc. 305 Denver Avenue, Suite D Fort Lupton, Colorado 80621 From: Laura MacDonald, M.A., SWCA Project Architectural Historian Scott Phillips, M.A., RPA, SWCA Cultural Resources Technical Director Melanie Medeiros, M.A., RPA, SWCA Cultural Resources Principal Investigator Date: October 25, 2022 Re: Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado / SWCA Project No. 76147 J&T Consulting, Inc. (J&T Consulting) contracted SWCA Environmental Consultants (SWCA) to conduct a cultural resource review and reconnaissance survey to support the proposed Fairmeadows RV Storage Facility and Gravel Mining Pit Project (project). The project consists of the new construction of a recreational vehicle (RV) storage yard and gravel mining pit on an approximately 86 -acre lot (Parcel No. 096103300067), hereafter referred to as the project area, in Greeley, Colorado, on mostly undeveloped farmland owned by Sunset Industrial, LLC (Sunset Industrial) (Figures 1 and 2). Development of the RV storage facility, which will cover approximately 25 percent of the parcel, will be subject to permitting through Weld County, and development of the gravel mining pit, which will cover the remaining 75 percent of the parcel, will be subject to permitting with both Weld County and the State of Colorado. The purpose of the review and reconaissance survey is to assess the project area for the presence of archaeologically and potentially sensitive cultural areas to assist J&T Consulting and the project proponent in determining if any pre-existing cultural resource issues may impact the project and to support both the county -level and state -level project permitting. This technical memorandum provides a description of the project area and land use, the methods used by SWCA cultural resources specialists to complete the review and reconnaissance survey, a summary of the results of the review and the reconnaissance survey, and recommendations as they relate to the proposed project. PROJECT AREA AND LAND USE The project area is located northeast of the East 8th Street / Colorado State Highway 263 and Weld County Road 43 intersection at 1507 East 8th Street in Greeley, Weld County, Colorado, on the west side of Section 3 of Township (T) 5 North (N), Range 65 West (W), as depicted on the 1950, 1980 photorevised, U.S. Geological Survey (USGS) Greeley, Colorado, 7.5 -minute quadrangle (see Figures 1 and 2). Aerial imagery of the project area depicts the parcel as an approximately 50 -percent -disturbed (mechanically graded) open farm field within the irregularly shaped parcel, surrounded on the north and east by low-rise hills covered in open grasslands and sparse tree clusters. A series of four building clusters are at the base of the low hills.

Project area, showing the proposed RV storage and mining pit areas, overlaid on aerial imagery. 3 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado The southern portion of the property, where the gravel mining operation is to be located, is an open agricultural field that is currently fallow and bare. That field is on a lowland terrace of the Cache la Poudre River, the channel of which is 0.2 mile south of the property, across East 8th Street. Soils in the project area are characterized as Aquolls and Aquents, gravelly substratum; Ellicott -Ellicott sandy - skeletal complex, 0 to 3 percent slopes, rarely flooded; and Ustic Torriorthents, moderately steep (Natural Resource Conservation Service 2019). All of these soils consist of alluvial deposits of sand overlying gravelly sand. The reconnaissance survey confirms that the field lacks topsoil and has been affected by plowing into alluvial sediments consisting of cobbles, gravels, and sand. No soil horizon remains able to support subsurface archaeological materials. A few cornfields stand on the margins of adjacent properties; however, this portion of East 8th Street, on the east exurban edge of the City of Greeley, is primarily mixed industrial. Industrial complexes, including a multi -head oil/gas well, are across East 8th Street to the immediate southwest and southeast of the project area and on its west side. An oil/gas well is located in the southeast corner of the project area at East 8th Street. One oil well was on the northwestern edge of the property until between 2006 and 2010, and another oil well was on the northeastern edge of the field until between 2016 and 2017, based on Google aerial images (Google Earth 2022); these wells have since been reclaimed. The Greeley -Weld County Airport is immediately to the east and northeast of the project area. And an existing gravel mining complex is on the immediate south side of the Cache la Poudre River, south of the project area. PREVIOUS WORK On September 29, 2022, SWCA conducted a file search and literature review through the Colorado Office of Archaeology and Historic Preservation (OAHP) online database (COMPASS) to identify all previously conducted cultural resource inventories and all previously identified cultural resources within the Public Land Survey System section containing the project area. File Search Results of the OAHP file search indicate that three cultural resource inventories have been previously conducted in Section 3, TSN, R65W (Table 1). Two of these inventories were conducted for the nearby Greeley -Weld County Airport and the third was conducted for a large-scale fiber-optic project. None of the previous inventories intersect the proposed project location, although one of the surveys conducted for the airport (WL.FA.NRS) discusses the historic buildings located in the project area (see discussion below). The closest previous inventory (MC.CH.R88), conducted in 1999, is adjacent to the southern border of the proposed project location; spatial data for this project is not available for review on COMPASS. WL.FA.NRS, conducted in 1980, identified the project area as having been previously owned by Robert Davis, with original structures dating from 1900 having been demolished. In 1980 the project area was owned by the Fair Meadows Land Company and contained several structures. According to WL.FA.NRS report author Kathleen A. Engels, "A ranch style dwelling with wood windows and a brick exterior on a concrete foundation was built in 1900. Other structures include a grain elevator which was constructed during 1948. Sheds, a stable, and other outbuildings typically associated with a farm were built during the 1930's" (Engels 1980:13). Engels concluded the Davis Farm should not be considered eligible for the National Register of Historic Places (NRHP) because it represents a style of architecture that is common to the area, and because the buildings are not integrally associated with any defined districts and do not represent a district when grouped together (Engels 1980:15). 4 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Table 1.

Wolff Garden Associates, Resource Survey Ltd. As a result of these previous inventories, one cultural resource has been recorded and assigned a Smithsonian trinomial number, a segment of the historic Ogilvy Ditch (Table 2). Ogilvy Ditch (5WL2944) was built in 1881 and was recommended as eligible for both the NRHP and the State Register of Historic Places (SRHP). The recorded segment of the ditch, SWL2944.1, is located 80 feet south of the project area as it runs parallel to East 8th Street / Colorado State Highway 263 (Highway 263). No archaeological sites have been previously recorded within the project area. Of note and as discussed above, the Davis Farm was identified as being located in the project area in inventory report WL.FA.NR5. Although the farm was superficially assessed for historical significance in that report, the farm has not been formally recorded nor has it been assigned a Smithsonian trinomial number. Table 2.

The 1902 USGS Greeley, Colorado, 1:125,000 -scale quadrangle shows the project area to be 2 miles east of the developed part of the town of Greeley in the area of Pleasant Valley, with no buildings or other built features present. Just outside the project area is a robust network of irrigation canals and one building located 350 feet southwest of the southwest corner of the project area. The 1950 USGS Greeley, Colorado, 1:24,000- 5 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado scale quadrangle shows the project area with many of its current features (see Figure 1), with a few variations. First, the access road branches off of Highway 263 and proceeds north to pass the houses and outbuilding, but instead of curving around the field and back into Highway 263, as it does today, the road continues north for half a mile to connect to Bliss Road. Second, a residence is shown within the project area northeast of the field, where the gravel pit is proposed, where none exists today. And third, the house at 1515 East 8th Street is not shown despite having been built in 1938, indicating that house may have been moved to its current location from within the project area. General Area History Greeley began as the Union Colony of Colorado (Union Colony), an experimental utopian farming community founded in 1869 by Nathan Cook Meeker, an agricultural reporter for the New York Tribune. Meeker and former Union Civil War General Robert Alexander Cameron were part of a committee that traveled to Colorado to find a location for their colony. They purchased 12,000 acres at the confluence of the Cache la Poudre and South Platte Rivers. The colony successfully attracted investors and settlers to buy lots that would then fund civic improvement. Union Colony leadership then established the town of Greeley in 1870. Greeley was named after Horace Greeley, the editor of the New York Tribune, who supported Meeker in creating the Union Colony and who popularized the phrase "Go West, young man." As the town grew, the farming community compensated for the arid climate by creating an extensive network of reservoirs and irrigation channels (Ely 1902; Kroepsch 2020; Worster 1985:83-84). The project parcel (Parcel No. 096103300067) is currently zoned industrial and owned by Sunset Industrial. In 2022, Sunset Industrial acquired the property through Fairmeadows Liquidation Trust, which had transacted the property previously with Stanley F. Davis (or his estate), according to Weld County Clerk and Recorder records online (Weld County 2022a). The portions of the southwest quarter of Section 3 and adjacent lands in TSN, R65W containing the project area were originally patented in 1894 through cash entry by Joel E. Davis, according to online GLO records (BLM 2022). Joel Edwin Davis (1831-1899) of Greeley should not be confused with another J. E. Davis who lived and farmed south of Greeley at Big Bend/Peckham, in the late 1800s and early 1900s. Joel Edwin Davis (Figure 3) was investing in lands around Greeley prior to 1894, according to the A History: Greeley and the Union Colony (Boyd 1890). J. E. Davis, originally a confederate of the South, arrived in Greeley in 1873 and became a farmer and financier. He was primarily an investor and rented out his properties, according to Boyd (1890:413-414). Therefore, the Davis family does not appear to have resided on the land within the project area but was the landlord of a property that was rented from the beginning of its development. The Greeley Tribune, on August 10, 1899, noted Joel Edwin Davis's funeral and that "[h]e was known as one who treated his neighbors and tenants well." Various articles in the Greeley Tribune in the 1890s indicate J.E. Davis lived locally and that he held properties deeded from the Union Colony, although the proposed project area is outside the sited colony lands. At the time of his death, Joel Edwin Davis's home is noted by the Greeley Tribune to be at 7th Avenue and 10th Street. He died from the effects of a stroke suffered in 1896. Based on a Greeley Tribune article on April 14, 1898, this was his son Stanley's house (built in 1898). In 1908, his wife. Ella (age 78, n�e Northcross) is noted by the Greeley Tribune (January 16, 1908) as passing away at 828 Tenth Street, Greeley. Davis had one son, Mr. Stanley Davis of Greeley, and three daughters: Mrs. Lulu Burr of Greeley, Mrs. Nellie Patton of Boulder, and Mrs. Daisy Carney of Denver, according to his Greeley Tribune obituary. Stanley Davis and wife (n�e Harrington) had a son, Franklin (Colorado Historic Newspapers Collection [CHNC] 2022). Stanley continued to rent out farms and ranches in the area, as apparent from the Greeley Tribune in the early 1900s. According to FamilySearch, which compiles census and related data, this was Edwin Stanley Davis (1868-1925), and he and his wife, Lida Harrington Davis (1872-1963), had one son, Franklin Burr Davis (1898-1951); Franklin had a son, Robert Stanley Davis (1929-1974), as well as two daughters (Intellectual Reserve, Inc. 2022). 6 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 3. Joel Edwin Davis, born 1831, died 1899 (Intellectual Reserve, Inc. 2022). Reconnaissance Survey On September 14, 2022, SWCA Cultural Resource Technical Director Scott Phillips completed a reconnaissance survey of the project area to identify cultural resources and potential impacts the project may have on those resources. As a result of this survey, four historic farmsteads 5WL9410, 5WL9411, 5WL9412, and 5WL9413 were recorded (Figure 4). 7 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado 0 Cultural Resource Project Area Proposed Mining and Water Storage Cell RV Storage Section Boundary Weld County, CO USGS 7.5' Quadrangle: Greeley, CO, 40104-D6 5N 65W Section 03 NAD 1983 UTM Zone 13N 40.4267°N 104.6535°W Base Map: ESR!ArcGIS Online. accessed October 2022 Updated: 10125/2022 Protect No. 76147 Layout: 76147 _Fai rm e a d ows_CR_Reso u rc es Aprx. 76147_F a i rme ad aws 0 N A 1:5,000 200 400 !• IFeel Meters 50 100 ENVIRONMENTAL CONSULTANTS Figure 4.

These houses are on the north edge of the terrace where it meets a fallow field (Figure 6) and on the low rise of the next terrace north. Soils are poorly sorted alluvial sediments consisting of cobbles, gravels, and sand (Figure 7). Topsoil is generally absent in the project area and specifically at the buildings. The residential area has been used as rental housing into recent times and the area kept clean and free of trash and debris. No historic dumps or artifacts (no purple or other glass, ceramic, or metal debris, or miscellaneous building materials) are on -site. Storage piles on - site contain only cut cottonwoods from recent drought die -off events that intensified after 2012, based on Google Earth (2022) historic aerial imagery. The property currently has four residences with the addresses of 1507, 1515, 1519, and 1539 East 8th Street, with the address numbers increasing from southwest to northeast following the terrace edge. The brick house at 1539 East 8th Street appears to be the oldest and is likely the original farmhouse built around the turn of the twentieth century. This house is outside the gravel mining pit area but is adjacent to the proposed RV storage area. Its outbuildings and enclosed porch addition are wood -framed in a manner similar to the house immediately to the southwest. The house at 1519 East 8th Street likely represents a later expansion of the original farm complex, ca. 1938, according to Weld County Assessor records (Weld County 2022b), which is consistent with the building style.

The Weld County property assessment indicates that this house was built in 1905, and that date is supported based on the style of its original siding and framing apparent in the 2001 assessment photograph (Weld County 2022b). However, its foundation appears to be a robust concrete that may have been added or replaced later; it is possible, but unknown whether the house was moved to the property at a later date. The rear addition is obviously from after the original construction of the house; its east- northeast extent appears to have allowed for the introduction of an indoor bathroom. The back steps are wood replacement steps; the front porch is weathered concrete with a newer concrete sidewalk curving outward from it. Its siding has recently been replaced along with all windows and doors, a recurring trend for wood -framed houses on the property. The roof has been recently re -shingled in gray asphalt tiles, another recurring trend for houses on the property. Under the overhanging eaves of the roof, the exposed rafter ends are braced on the gable ends of the house. The front (south) and east side yards are fenced in a low chain link fence without a top rail, and the backyard has a higher chain link dog run. A propane tank is behind the house to the northwest. A multi -head gas well facility is a recent addition on the neighboring property to the northwest of the house. The house has no outbuildings associated with it. Figure 8. Site 5WL9410, Feature 1, house, view to the northeast. 11 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 9. Site 5WL9410, Feature 1, house, view to the southwest. Although the house is on a property owned by a Union Colonist and early Greeley settler Joel Edwin Davis, he acquired the property later in life as an investment rather than it being directly tied to the family's historical prominence in the region. The property has remained investment/rental property ever since. The house does not present significant or masterful architectural elements of design or materials. The house has had incongruous changes and additions made, including additions that distort its shape and mass, replacement window openings, and changes to the siding and entry openings. The property lacks significance and integrity under any NRHP criteria. 5WL9411 -1515 East 8th Street SWCA newly recorded SWL9411, a historic farmstead at 1515 East 8th Street, consisting of a house (Feature 1) and garage (Feature 2). The house is wood -framed and on an irregular footprint. Based on Weld County records, the house was built in 1938, the same year as the house at 1519 East 8th Street (5WL9412), which is consistent with its construction style (Figures 10 and 11). Overall, the building has had additions through time, including a shed roof extension of the back (north) and a shed -roofed entry room on the northeast corner. The main, original house has a cross -gabled roof, and the original footprint would have been T-shaped. The eaves are enclosed, with no rafters exposed. Roof shingles are new gray asphalt tiles. Like the house discussed previously (1507 East 8th Street/SWL9410), it is apparent from Weld County Assessor photographs from 2001 that earlier horizontal wood siding on this house has been replaced. The window openings have been refit with smaller aluminum -framed windows and the front door has been refit with a non -period door. The foundation is concrete as are the porches. Feature 2 is a concrete block garage that sits northeast of the house (see Figures 10 and 11). The garage has a double door (plywood) single entry in its south end. The Weld County Assessor photograph from 2001 shows this building as having a metal roll -up garage door. Several extensions have been added to the rear of this shed -roofed building, which has a corrugated sheet -steel roof. The yard of the house is fenced with low chain link fencing that connects from the garage to the house. 12 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 10.

Site 5WL9411, Feature 1 (house) on left, Feature 2 (garage) on right, view to the west. Although the house and garage are on a property owned by a Union Colonist and early Greeley settler Joel Edwin Davis, he acquired this property later in life as an investment rather than it being directly tied to the family's historical prominence in the region. The property has remained investment/rental property 13 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado ever since. The house does not present significant or masterful architectural elements of design or materials. The house has had incongruous changes and additions made, including additions that distort its shape and mass, replacement window openings, and changes to the siding and entry openings. The property lacks significance and integrity under any NRHP criteria. 5WL9412 -1519 East 8th Street SWCA newly recorded 5WL9412, a historic farmstead at 1519 East 8th Street, consisting of a house (Feature 1), garage (Feature 2), concrete block outbuilding (Feature 3), Quonset hut (Feature 4), worker's cottage (Feature 5), and concrete building foundation (Feature 6). The house at 1519 East 8th Street will be left in place and kept as an employee residence for the project; however, the outbuildings on the property may be removed. Feature 1 is currently the only occupied residence in the series of houses on the project property (Figures 12 and 13). Based on Weld County records, the house was built in 1938, and its construction is consistent with that assessment. The house at 1515 East 8th Street (5WL94 11) was also built in 1938. The house is now on an L-shaped footprint but appears to originally have been built rectangularly. An entryway wing on the southeast corner appears to be a later addition, as does a westward extension on the front of the main body of the house. The horizontal wood siding on the exterior walls appears to have been replaced throughout the building. The front (south) windows have all been replaced with more recent casement windows, whereas the side and rear fa�ades retain double sash wood -framed windows. The roof is hipped on the east side, front -gabled over the entry wing, and end -gabled over the west fa�ade. Roof shingles are new gray asphalt; however, the adjacent garage (Feature 2) has older wood singles. A single brick chimney is centered on the roof. The eaves have exposed rafters. The foundation and porches are concrete. A crawl space opening is apparent at the front of the building. The door at the original front entry appears to be a recent replacement, although the door in the added entry wing appears to be older and original. Feature 2 is a garage immediately on the west side of the house (see Figures 12 and 13). The rectangular end -gabled single -bay garage is wood framed, like the house. However, its siding appears to be the original wood planks, and its wood roof shingles also remain. It has a double -entry door of vertical wood planks on its front fa�ade (south). The rear (north) of the garage is composed of concrete blocks where it is built into the earth slope behind it. The concrete blocks have triangular support sections flaring from the base where the garage faces the slope. In front of the garage is a new, prefabricated garden shed, constructed to look like a small red barn. Similarly, a new small red barn —style chicken coop is located on the east side of the house. 14 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 12. Site 5WL9412, Feature 2 (garage) on left, Feature 1 (house) on right, view to the north. Figure 13. Site 5WL9412, Feature 1 (house), with Feature 2 (garage) on the far right, view to the southwest. Three farm outbuildings are located on the entry drive to the house: a full concrete block building (Feature 3), a large corrugated steel Quonset hut (Feature 4), and a small modular worker's cottage (Feature 5). All three outbuildings are oriented at a 45 -degree angle off of north, with roof ridgelines 15 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado running southeast to northwest. This contrasts with all the house and garage buildings on the property that are oriented south and generally align to the cardinal compass directions. Feature 3 is a concrete block building that was likely used as a garage, shop, or equipment shed (Figures 14-17). Feature 3 is located approximately 300 feet southwest of the house (Feature 1), is aligned parallel and adjacent to the larger Quonset hut (Feature 4), and is the second concrete block building at the site besides the garage (Feature 2). The rectangular building has an end -gabled roof with horizontal wood siding under the gables between the roofline and concrete block wall. The roof is covered in corrugated steel roofing panels and the rafters are exposed at the eaves. The building has a double -bay set of roll -up garage doors on the southwest facade. On the northwest and northeast facades, it has paired, multi-lite double sash wood -framed windows with brick sills that have hardware mesh exterior screens bolted to the building's exterior.

Site 5WL9412, Feature 3 (concrete block building) north corner with back (northeast) fa�ade on left, and partial northwest fa�ade on right, view to the south. Feature 4 is a Quonset hut utility shed, a long rectangular building with an arched roof that continues downward to function as walls, creating a half -cylinder building volume (Figures 18-20; see Figures 14- 16). The Quonset hut is clad in corrugated steel with a two -door single bay entry centered on the southwest end. Two pairs of six-lite windows are set on either side of the entry bay, and a louvered air vent is set above the entry bay. On the east half of the southeast side of the outbuilding are six additional six-lite windows. The semicircular northeast facade of the outbuilding has a similar bay opening and windows as the southwest end; however, the northeast facade also has a corrugated steel —sided (shed - roofed) entry room added on its north corner. The entry room has the same six-lite windows as the main Quonset hut as well as a small cement -surfaced chimney on its northeast side (see Figures 16 and 18). The Quonset hut is consistent with Stran-Steel models (prefabricated kits) dating to World War II and after (Thomas 2003). Weld County's assessed date of 1950 for this building is likely accurate. 18 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 18.

Site 5WL9412, Feature 5 (worker's cottage) south corner, with Feature 4 (Quonset hut) on left, view to the north. Feature 5 is a small worker's cottage located south and across the dirt driveway from the Quonset hut (Figures 21 and 22; see Figures 14, 18, and 20). It is a modular unit on a rectangular concrete footprint. It appears to have been prefabricated at its current position to take advantage of electricity from the power pole, located off its northeast side. Another building was previously set in parallel to the northwestern side of the cottage; however, only a concrete foundation remains, including a covered well opening centered near the south side and abutting the cottage. The wood -framed cottage is clad in horizontal lapboard siding. It has an end -gabled roof and opens to the southwest through a wood doorway set in the west side of the southwest facade, which has a double sash wood -framed window opening beside it. Double sash window openings are spaced along the other facades as well; however, only one doorway exists. The cottage is for temporary housing only, with a sitting room and gas stove at the front and a bedroom at the rear. A single brick chimney is centered on the roof peak. A propane tank is located behind (northeast of) the cottage. 20 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 21. Site 5WL9412, Feature 5 (worker's cottage) at center, with Feature 6 (concrete building foundation) at far left, view to the east. Feature 6 is the remains of a concrete building foundation set parallel to the northwest side of the worker's cottage and adjacent to the dirt driveway road (see Figure 22). A covered well opening is centered near the feature's south side and abutting the cottage. Although the house and its outbuildings are on a property owned by a Union Colonist and early Greeley settler Joel Edwin Davis, he acquired this property later in life as an investment rather than it being directly tied to the family's historical prominence in the region. The property has remained investment/rental property ever since. The house does not present significant or masterful architectural elements of design or materials. The house has had incongruous changes and additions made, including additions that distort its shape and mass, replacement window openings, and changes to the siding and entry openings. The property lacks significance and integrity under any NRHP criteria. 21 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 22. 5WL9412, Feature 6 (concrete building foundation) at center, with Feature 5 (worker's cottage) at far left, and site 5WL9411 at in the center background, view to the southwest. 5WL9413 -1539 East 8th Street SWCA newly recorded 5WL9413, a historic farmstead at 1539 East 8th Street, consisting of a house (Feature 1), garage/shed outbuilding (Feature 2), outhouse (Feature 3), and well/pumphouse (Feature 4) (Figure 23). The buildings at 1539 East 8th Street are outside the planned mining permit area and are not planned for demolition as part of the gravel mining operations. However, according to the current owner, the viability of the house was challenged by a storm and treefall onto its roof sometime between 2019 and 2021; the former owner had been refurbishing the house for occupation until a treefall and resulting water damage destroyed that effort. It is apparent that roofing tiles were replaced between 2016 and 2017 based on aerial imagery available from Google Earth (2022). As can be seen in the aerial imagery, four to five dead trees stand around the house in July 2019, and in June 2021, aerial imagery shows these trees have been removed. The building stands derelict. 22 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 23. Site 5WL9413, Feature 4 (well/pumphouse) on left, Feature 1 (house) at center, and Feature 2 (garage/shed outbuilding) on right, view to the northeast. Feature 1 is a single -story brick house on an L-shaped footprint, with a late addition enclosing the front porch on the south fa�ade with a shed roof and wood cladding (Figures 24-27; see Figure 23). Weld County Assessor records indicate it was built in 1900 (Weld County 2022b). The house lacks a distinct style, borrowing elements from the time of its construction, including a square main mass with hipped roof, and most original window openings are crowned with a lintel of vertically set bricks with shaped Dakota sandstone windowsills. None of the windows in the brick walls appear to be original; all have added double sash window lites with added framing to center them in the opening. Only the enclosed wood front porch may have original six-lite casement windows (a connected row of three on front); however, the porch's side windows may also have been replaced. Each building fa�ade has one to three windows. The front door and porch are centered on the south fa�ade and the back door is centered in front of a (later addition) plank deck on the north elevation. The house appears to have a coal cellar opening on the western edge of the south fa�ade. The building sits either on a concrete foundation or on a stone or block foundation that is surfaced with cement. The hipped roof is currently and recently tiled with basic brown asphalt shingles, matching the adjacent outbuildings. The main north mass of the building has a square -hipped roof rising to a small square flat top. The south leg of the L-shaped house is rectangular and covered with a cross -hipped roof. A rear dormer, also hipped, is centered on the north side and serves as an attic vent. Plumbing vents made of recently added polyvinyl chloride pipes protrude from the west side of the roof. A propane tank on the east side of the house suggests propane heating. 23 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado .34.I_ First Floor 121'7.7' 44 7' 11 5 14.0' i' I: I r , I I 1 1 Ill 1 1.1 - a._ 14.ii' Er-i I Solid ".u'"."aII Figure 26.

Feature 2 is a wood -framed and wood -clad outbuilding, which may have served as a garage and shed, has horizontal lapboard siding that matches the front porch addition on the house (Figure 28; see Figures 23 and 27). The wood siding at both buildings is similar to and likely contemporaneous to the wood -framed farmhouse adjacent to it at 1519 East 8th Street (5WL9412). The end -gabled rectangular garage building 25 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado has an end -gabled shed added on its east end. The outbuilding appears to have been converted to a two - bay garage, with the bay doors (currently off the building) made of plywood. Based on vertical siding placed between the two bays, this west end of the outbuilding may have been entirely open on the front (south side) before renovations in recent years. The attached shed has a separate two -door entry set on the west end of its south side. A nine-lite window is adjacent to the entry and centered in the south fa�ade of the shed. The east end of the shed has been reclad and repaired recently. The roof has also recently been reclad with brown asphalt shingles matching those of the house. The roof of the shed is asymmetrical, and more sloped at the rear (north side) of the building. Unlike the adjacent house, the shed and garage have exposed rafters at the eaves. Figure 28. Site 5WL9413, Feature 2 (garage/shed outbuilding), view to the north. Feature 3 is a small outhouse structure southeast of the garage/shed outbuilding (Figure 29). It is constructed the same as the garage/shed outbuilding, clad in horizontal wood siding (abutted rather than lapped or joined planks). In contrast, the off -center door, facing the farm complex, is made of vertical planks. The north fa�ade has a tiny square unglazed vent window centered in its upper portion. The shed roof on the outhouse appears to have been replaced. The outhouse is set over an open, oversized hole that appears to have been dug in recent years and the structure moved over it and, without deposition, would not have further archaeological potential. 26 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 29. Site 5WL9413, Feature 3 (outhouse), view to the southeast. Feature 4 is a well/pumphouse located southwest of the house (see Figure 23). It is covered in a front - gabled roof clad in brown asphalt tiles that are older and do not match the roofing material on the house and garage/shed outbuilding. The small structure's sides are covered in overlapping horizontal wood cladding that matches the enclosed porch on the house. It sits on a rectangular cement foundation. An undersized plywood door is centered on the south -facing fa�ade, under the gable of the roof. Although the house and its outbuildings are on a property owned by a Union Colonist and early Greeley settler Joel Edwin Davis, he acquired this property later in life as an investment rather than it being directly tied to the family's historical prominence in the region. The property has remained investment/rental property ever since. The house does not present significant or masterful architectural elements of design or materials. The house and outbuildings have had incongruous changes and additions made to them, including the mismatched porch and replaced window openings on the house and changes/repairs to the siding and entry openings on the outbuildings. The property lacks significance and integrity under any NRHP criteria. CONCLUSIONS AND RECOMMENDATIONS Given the level of heavy agricultural use occurring on this parcel, confirmed by the reconnaissance survey, no native sediments that could have harbored precontact or early historic archaeological sites remain in the project area. Therefore, no additional archaeological assessment is recommended. The project area holds four historic farmsteads (5WL9410-5WL94l3) with houses dating between 1900 to 1938; however, all buildings and structures have been heavily modified from their original historic look, do not represent masterful architectural works, and are not closely associated with notable historical figures. All the buildings and outbuildings lack significance and integrity under any NRHP or SRHP criteria. Therefore, SWCA recommends that 5 WL9410, 5 WL9411, 5WL9412, and 5WL9413 are not 27 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado eligible for the NRHP or the SRHP and that no historic properties will be affected by the development of the Fairmeadows RV Storage and Gravel Mining Pit Project. No additional work related to historic architectural resources is recommended. 28 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado REFERENCES CITED Boyd, David 1890 A History: Greeley and the Union Colony.

The Weld County property assessment indicates that this house was built in 1905, and that date is supported based on the style of its original siding and framing apparent in the 2001 assessment photograph (Weld County 2022). However, its foundation appears to be a robust concrete that may have been added or replaced later; it is possible, but unknown whether the house was moved to the property at a later date. The rear addition is obviously from after the original construction of the house; its east-northeast extent appears to have allowed for the introduction of an indoor bathroom. The back steps are wood replacement steps; the front porch is weathered concrete with a newer concrete sidewalk curving OAHP Site #: 5WL9410 OAHP Form #1417 outward from it. Its siding has recently been replaced along with all windows and doors, a recurring trend for wood -framed houses on the property. The roof has been recently re -shingled in gray asphalt tiles, another recurring trend for houses on the property.

Based on Weld County records, the house was built in 1938, the same year as the house at 1519 East 8th Street (5WL9412), which is consistent with its construction style. Overall, the building has had additions through time, including a shed roof extension of the back (north) and a shed -roofed entry room on the northeast corner. The main, original house has a cross -gabled roof, and the original footprint would have been T-shaped. The eaves are enclosed, with no rafters exposed. Roof shingles are new gray asphalt tiles. Like the house discussed previously (1507 East 8th Street/5WL9410), it is apparent from Weld County Assessor photographs from 2001 that earlier horizontal wood siding on this OAHP Site #: 5WL9411 OAHP Form #1417 house has been replaced. The window openings have been refit with smaller aluminum -framed windows and the front door has been refit with a non -period door. The foundation is concrete as are the porches. 14.

Feature 1 is currently the only occupied residence in the series of houses on the project property. Based on Weld County records, the house was built in 1938, and its construction is consistent with that assessment. The house at 1515 East 8th Street (5WL9411) was also built in 1938. The house is now on an L-shaped footprint but appears to originally have been built OAHP Site #: 5WL9412 OAHP Form #1417 rectangularly. An entryway wing on the southeast corner appears to be a later addition, as does a westward extension on the front of the main body of the house. The horizontal wood siding on the exterior walls appears to have been replaced throughout the building. The front (south) windows have all been replaced with more recent casement windows, whereas the side and rear fa�ades retain double sash wood -framed windows. The roof is hipped on the east side, front -gabled over the entry wing, and end - gabled over the west fa�ade. Roof shingles are new gray asphalt; however, the adjacent garage (Feature 2) has older wood singles. A single brick chimney is centered on the roof. The eaves have exposed rafters. The foundation and porches are concrete. A crawl space opening is apparent at the front of the building. The door at the original front entry appears to be a recent replacement, although the door in the added entry wing appears to be older and original. 14.

The Quonset hut is clad in corrugated steel with a two -door single bay entry centered on the southwest end. Two pairs of six-lite windows are set on either side of the entry bay, and a louvered air vent is set above the entry bay. On the east half of the southeast side of the outbuilding are six additional six-lite windows. The semicircular northeast fa�ade of the outbuilding has a similar bay opening and windows as the southwest end; however, the northeast fa�ade also has a corrugated steel —sided (shed -roofed) entry room added on its north corner. The entry room has the same six-lite windows as the main Quonset hut as well as a small cement -surfaced chimney on its northeast side. The Quonset hut is consistent with Stran-Steel models (prefabricated kits) dating to World War II and after (Thomas 2003). Weld County's assessed date of 1950 for this building is likely accurate.

It is a modular unit on a rectangular concrete footprint. It appears to have been prefabricated at its current position to take advantage of electricity from the power pole, located off its northeast side. Another building was previously set in parallel to the northwestern side of the cottage; however, only a concrete foundation remains, including a covered well opening centered near the south side and abutting the cottage. The wood -framed cottage is clad in horizontal lapboard siding. It has an end -gabled roof and opens to the southwest through a wood doorway set in the west side of the southwest facade, which has a double sash wood -framed window opening beside it. Double sash window openings are spaced along the other facades as well; however, only one doorway exists. The cottage is for temporary housing only, with a sitting room and gas stove at the front and a bedroom at the rear. A single brick chimney is centered on the roof peak.

Stories Style/Type Foundation Walls 1 No style Poured concrete Brick Windows Roof Chimney Porch 14 sash windows, and double casement hung Complex dormers, hipped, asphalt tile with Brick, interior Front roof, deck is enclosed back is open with wood shed Optional: additional description (plan/footprint, dimensions, character -defining and decorative elements of exterior and interior; alterations, additions, etc.): Feature 1 is a single -story brick house on an L-shaped footprint, with a late addition enclosing the front porch on the south facade with a shed roof and wood cladding. Weld County Assessor records indicate it was built in 1900 (Weld County 2022). The house lacks a distinct style, borrowing elements from the time of its construction, including a square main mass with hipped roof, and most original window openings are crowned with a lintel of vertically set bricks with shaped Dakota sandstone windowsills. None of the windows in the brick walls appear to be original; all have added double sash window lites with added framing to center them in the opening. Only the enclosed wood front porch may have original six-lite casement windows (a connected row of three on OAHP Site #: 5WL9413 OAHP Form #1417 front); however, the porch's side windows may also have been replaced. Each building fa�ade has one to three windows. The front door and porch are centered on the south facade and the back door is centered in front of a (later addition) plank deck on the north elevation. The house appears to have a coal cellar opening on the western edge of the south facade. The building sits either on a concrete foundation or on a stone or block foundation that is surfaced with cement. The hipped roof is currently and recently tiled with basic brown asphalt shingles, matching the adjacent outbuildings. The main north mass of the building has a square - hipped roof rising to a small square flat top. The south leg of the L-shaped house is rectangular and covered with a cross -hipped roof. A rear dormer, also hipped, is centered on the north side and serves as an attic vent. Plumbing vents made of recently added polyvinyl chloride pipes protrude from the west side of the roof. A propane tank on the east side of the house suggests propane heating 14.

The property has remained investment/rental property ever since. The house does not present significant or masterful architectural elements of design or materials. The house and outbuildings have had incongruous changes and additions made to them, including the mismatched porch and replaced window openings on the house and changes/repairs to the siding and entry openings on the outbuildings. The property lacks significance and integrity under any NRHP criteria. 22. Sources: Weld County 2022 Weld County Property Portal. Available at: https://propertyreport.co.weld.co.us/?account=R2581503.

The wood siding at both buildings is similar to and likely contemporaneous to the wood -framed farmhouse adjacent to it at 1519 East 8th Street (5WL9412). The end -gabled rectangular garage building has an end -gabled shed added on its east end. The outbuilding appears to have been converted to a two -bay garage, with the bay doors (currently off the building) made of plywood. Based on vertical siding placed between the two bays, this west end of the outbuilding may have been entirely open on the front (south side) before renovations in recent years. The attached shed has a separate two -door entry set on the west end of its south side. A nine-lite window is adjacent to the entry and centered in the south fa�ade of the shed. The east end of the shed has been reclad and repaired recently. The roof has also recently been reclad with brown asphalt shingles matching those of the house. The roof of the shed is asymmetrical, and more sloped at the rear (north side) of the building. Unlike the adjacent house, the shed and garage have exposed rafters at the eaves.

In contrast, the off -center door, facing the farm complex, is made of vertical planks. The north facade has a tiny square unglazed vent window centered in its upper portion. The shed roof on the outhouse appears to have been replaced. The outhouse is set over an open, oversized hole that appears to have been dug in recent years and the structure moved over it and, without deposition, would not have further archaeological potential.

Mr. Peter Hays Environmental Protection Specialist State of Colorado Division of Reclamation, Mining, & Safety 1313 Sherman Street — Room 215 Denver, CO 80203 RE: J-2 Contracting Company, Sunset Industrial Pit, File No. M-2023-001, 112c Permit Application Adequacy Review Response Dear Mr. Hays, J-2 Contracting Company (J-2) has received the Division's Adequacy Review of the 112 Construction Materials Reclamation Permit Application letter dated April 6, 2023. Below are the comments and the corresponding responses that we have provided to address the comments. Comments 1. The Division received state agency comments from History Colorado, Colorado Parks and Wildlife, Division of Water Resources and public comments from Anderson's Sales & Salvage, Inc. Copies of the comment letters were emailed to the Applicant as they were received by the Division and are attached. Please address the comments in the letters and revise the permit application accordingly. No objections to the permit application were received by the Division during the public comment period. Response: We provided information back to History Colorado on February 23, 2023, regarding the cultural resources survey that was conducted by SWCA and included in the application package to the DRMS. History Colorado responded back via e-mail thanking us for sending over and would reach out if they had any questions. We have not received any questions from them since they provided the response on February 23, 2023. We have met with CPW along with our environmental consultant, ERC. We provided responses back to CPW through ERC regarding their comments. The response ERC provided back to CPW and CPW's e-mail response are attached dated April 3, 2023. The comments from DWR will be addressed once approval is received from the DRMS as J-2 Contracting Company will obtain a well permit, substitute water supply plan approval, document all wells within 600 feet of the proposed well permit and obtain waivers, if possible, from well owners within 600 feet of the proposed well permit. All of these items will be pursued and obtained prior to exposing groundwater at the pit. J-2 Contracting Company commits to providing these approvals prior to exposing groundwater. The groundwater model provided to the DRMS indicates that mounding will be minimal for the proposed slurry wall and not 305 Denver Avenue — Suite D • Fort Lupton CO 80621 • Ph: 303-857-6222 RE: J-2 Contracting Company, Sunset Industrial Pit, File No. M-2023-001, 112c Permit Application Adequacy Review Response 4/19/23 -2- affect the existing aquifer. Monitoring wells have been installed to monitor groundwater levels before and after the slurry wall is installed. These will be monitored monthly for the life of the mine and can determine if mitigation is necessary to mitigate effects from mounding or shadowing from the slurry wall. Based on information in the groundwater model we don't anticipate the slurry wall will have effects that would require mitigation. The comments from Anderson's Sales and Salvage, Inc. will be addressed during the Weld County Use by Special Review permit process. J-2 Contracting Company has a traffic consultant preparing a traffic study to determine the warranted traffic improvements based on the impact of the proposed traffic from the Sunset Industrial Pit. The City of Greeley controls the access and improvements that can be made for 8th Street. The City of Greeley will be providing comments in regard to any future traffic improvements and where they should be placed based on their review of the traffic study provided by J-2 Contracting Company to Weld County for the Use by Special Review Permit. 1.6 Public Notice 2.

(ERC) provides this response to Colorado Parks and Wildlife (CPW) comment letter dated February 7, 2023 (CPW letter -Attached) for the Sunset Industrial Pit project (Project Site), located in Weld County, Colorado. This response specifically addresses concerns/recommendation: 2. Bald Eagle Roosting Area. CPW provided this comment as part of the Colorado Division of Reclamation, Mining & Safety review for M-2023-001 application. The CPW letter states that "Within the proposed mining project, there is overlap with Bald Eagle roosting habitat, a high priority habitat identified by CPW." ERC met with Jackson Davis, CPW District Wildlife Manager Area 4/Greeley North on March 16, 2023 near the Project Site to address the CPW letter concerns related to the potential eagle roost site (roost site) and project, evaluate site specific characteristics and discuss potential discrepancies on the available CPW mapping. It was determined that two different CPW mapping layers are available that relate to the potential roost site. First, ERC originally used the most recent downloadable CPW Species Activity Mapping (SAM) that was determined to depict the extents of a Bald Eagle Roost Site (FID 72) with a 1/4 -mile protective buffer (Refer to Figure 1). This 1/4 -mile protective buffer ends to the southwest outside of the Project Site by approximately 25 feet. ERC was then provided CPW mapping of the same area that assumed to depict a 1/2 -mile protective buffer around the potential roost site which does overlap a portion of the Project Site (Refer to Figure 2). Per CPW Recommended Buffer Zones and Seasonal Restrictions for Colorado Raptors (2020), no permitted, authorized or human encroachment activities should occur within 1/4 -mile radius of an active night and communal roost sites from November 15 through March 15 if there is no direct line of site and 1/2 -mile if there is a direct line of site between the roost and the activity. It should also be noted in areas determined "Highly Developed Area", these protective buffers are reduced to 1/8 -mile and 1/4 -mile respectively. The roost site and the Project Site would be considered a "Highly Developed Area" per CPW definitions as there are 10 or more daily occupied facilities within 1/4 -mile of the roost site. The active status of the roost site has not been confirmed herein. 1. Per CPW recommendations the Project Site is considered to be within a "Highly Developed Area" with no direct line of sight, therefore the 1/8 -mile recommended protective buffer should be considered for the Project Site. The 1/8 -mile protective buffer does not extend onto the Project Site. 2. Based on site specific conditions and CPW site meeting on March 16, 2023, a 1/4 -mile recommended protective buffer could be maintained without any restricts to proposed activities within the Project Site. A ERC CPW Bald Eagle Roost Site Comment Response Sunset Industrial Pit Project Figure 1. CWP Eagle Roost Site %-mile Recommended Protective Buffer (shaded area). Project Site depicted by red outline. ' Figure 2. CWP Eagle Roost Site 1/2 -mile Recommended Protective Buffer (shaded area).

Blue Circle = is the %-mile CPW recommended protective buffer = is the recommended %2 -mile CPW recommended protective buffer Red numbers = areas considered as part of Highly Developed Area Orange arrow = general obstructed line of sight from Project Site to potential eagle roost site Red outline = Project Site In conclusion, based on this evaluation and coordination with the CPW, the Project Site and proposed activities should not be restricted for protection of the potential eagle roost site. The Project Site will maintain a %-mile protective buffer which given site specific characteristics is larger than the CPW recommended guidelines. For additional consideration, gravel operations are not anticipated to occur within the 1/2 —mile protective buffer after sunset and before sunrise, during the most critical periods of roosting, between November 15 through March 15, therefore pMoving additional protections to the potential roost site. CPW concurred with the findings herein in an email response dated March 29, 2023 as attached. Ecological Resource Consultants, Inc. David J.

It is our understanding that the proposed mining operating will take place at or near Section 3, Township 5N, Range 65W in Weld County, just east of the Greeley city limits. It is also our understanding that the property will be mined in 2 pits and later reclaimed as a water storage reservoir, with a total finished footprint of approximately 54 surface acres. The mission of CPW is to perpetuate the wildlife resources of the state, to provide a quality state parks system, and to provide enjoyable and sustainable outdoor recreation opportunities that educate and inspire current and future generations to serve as active stewards of Colorado's natural resources. CPW has a statutory responsibility to manage al I wildlife species in Colorado, and to promote a variety of recreational opportunities throughout Colorado. The protection of wildlife habitats, wildlife, and access to hunting recreation are of extreme importance to CPW. CPW recommends that all proposed projects be assessed to avoid, minimize, or mitigate impacts to sensitive wildlife habitats and species. That includes species of concern, big game winter concentration areas, breeding and nesting habitats for sensitive ground -nesting birds, and nests of raptors sensitive to development to prevent the loss of habitat or fragmentation of habitat. One way we achieve this goal is by responding to referral comment requests, as is the case for this project. Heather Dugan.

Wildlife Conflict and Collisions with Adjacent Properties Please refer to CPW's Living with Wildlife -Canada Goose' Weld County and the Cache la Poudre River are important migration corridors for migratory birds, such as Canada Geese, Mallards, Sandh i I I Cranes, Bald Eagles, and a variety of other species. During the spring and fall migration, large flocks of waterfowl migrate throughout Weld County, frequently stopping at open fields and reservoirs to rest for the physically demanding conditions and distances they fly. It is common behavior for migrating avian species to stop at productive agriculture fields and open bodies of water, where predators are relatively scarce, and crucial habitat is available for resting. Many migratory birds, especially Ducks and Geese, require open bodies of water during all stages of their life cycles. By creating open bodies of water, waterfowl will be attracted year-round to this site to rest, rear young, and forage on available vegetation within the body of water and immediate surrounding area. While providing resting and feeding grounds to wildlife is important for conservation, placing an open water pit directly next to a municipal airport may increase collisions with landing aircraft, placing pilots and the airport in danger. CPW recommends that landscape modifications and/ or exclusions and barriers be put in place to discourage Canada Geese and other waterfowl species from selecting this site. Where possible, CPW recommends creating barriers on the shorelines (such as introducing hedges or fencing) to create a physical and visual barrier between the proposed water reservoir and the shoreline. By dissuading waterfowl from utilizing the banks of the water storage facility, waterfowl may avoid selecting the site, thereby decreasing the likelihood of collisions. Keeping in mind that creating natural vegetation takes time, it is advisable that temporary fencing be erected. If fencing is created, the fencing should be at least two (2) feet high and with openings no larger than three by three (3x3) inches. Sunset Industrial Pit — CPW Comments (02/07/2023) Page 3 of 3 No singular method to discourage waterfowl will prevent habitat selection by determined wildlife. Utilizing multiple methods, such as hazing with noisemakers, scare tape, and/or trained dogs in conjunction with landscape modifications may discourage waterfowl and other migratory birds from selecting open water, but these efforts must be done consistently and preferably each time Canada Geese and other species arrive on site. 2. Bald Eagle Roosting Area Please refer to CPW's Recommended Buffer Zones and Seasonal Restrictions.2 Within the proposed mining project, there is overlap with Bald Eagle roosting habitat, a high priority habitat identified by CPW. Due to the unique development landscape, and due to the high density of structures within the immediate roost site buffer, CPW recommends that no permitted or authorized human activities occur between November 15th to March 15th within one quarter mile, if line of site is present; or within 660 feet if the winter roost has no line of site. CPW also highly recommends pre -construction surveys to assess for other raptor species and nesting activity before construction begins.

EXHIBIT D Mining Plan Mining Limits J-2 Contracting proposes to mine in the land located in the E 1/2 of NW 1/4, the NE 1/4 of the SW 1/4, the E 1/2 of the SW 1/4 of the NW 1/4, and the E 1/2 of the NW 1/4 of the SW 1/4 of Section 3, Township 5 North, Range 65 West of the 6t" Principal Meridian, County of Weld, State of Colorado and that part of the SE 1/4 of the SW 1/4 and the E 1/2 of the SW 1/4 of the SW 1/4 of Section 3, Township 5 North, Range 65 West of the 6th Principal Meridian, County of Weld, State of Colorado lying North of the Eighth Street Road except that portion described in deed recorded September 24, 1982, at reception no. 1904628, Weld County, Colorado. The proposed mining site is located adjacent to the City of Greeley city limits on the north, east, and south property lines, as well as being adjacent to 8t" Street on the south property line. The Cache La Poudre River is approximately 700 feet south of the site on the south side of the permit boundary. 8t" Street is immediately adjacent to the south side of the permit boundary. Access to the site will be located at the southwest corner of the permit boundary off of 8th Street. The dominant land use surrounding the property is agricultural and industrial. An aggregate processing plant and recycle crushing area will be located in Phase 1 along the eastern boundary of Phase 1 including stockpiles of pit run and processed aggregates. Overburden/topsoil will be temporarily stored in this area prior to being used for reclamation. Overburden/topsoil will also be temporarily stored in the east side of Phase 2 prior to being used for reclamation, as well as stockpiles of pit run and processed aggregates. A future concrete and asphalt batch plant area will be located within the Phase 2 mining area as shown on the Mining Plan Maps. Additionally, these areas will contain portable equipment, storage bins, and silos as necessary to support the plant operations. Concrete truck washout and excess concrete product dumping will be included in the future Phase 2 area to ensure that waste materials are recycled and kept from entering the stormwater flows on the site. The concrete truck washout area will be a 30 -foot by 20 -foot three cell concrete structure. Concrete trucks will wash the residual product from their mixing drums and chutes into the first cell of the structure. The first cell spills into the second cell, which spills into the third cell. This allows the aggregate and suspended fines to settle into the cells over time. The water and settled material in the three cells are then removed as required and recycled into the concrete batch plant. Generally, the cells would be cleaned on a weekly schedule. The excess product dumping area will be approximately 50 feet by 100 feet and have an exterior berm to limit the migration of stormwater flows to and from the surrounding areas. Excess product that is deposited in this area will be allowed to cure for approximately 90 days until it becomes inert. It will then be crushed and recycled. All local, State, and Federal rules and regulations will be followed for the storage and handling of any fuel, asphalt, cement, flyash, and admixtures required for the batching facilities. hid I J .T Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application The permit boundary will encompass approximately 85.17 acres which will all be affected acreage, and approximately 72.10 acres being mined. The remaining area will consist of access roads and disturbed land. The following table depicts the different affected acreage: Affected Acreage Mining Plan Area (acres) Mined Area 72.10 Access Roads 0.70 Disturbed Land 12.37 TOTAL 85.17 Various setbacks from adjacent roads, adjacent structures, and oil and gas infrastructure will be maintained as mining occurs. All setbacks specified in the surface use agreements with the oil/gas companies will be followed. The final executed agreements are expected to be obtained in the near future and will be forwarded to the Division when they are available. A minimum 200 - foot setback from any existing oil/gas facility will be maintained until that time. See Exhibit C, Mining Plan Map, and the Slope Stability Report for the mining limit configuration and information on setbacks and their locations. The mineral deed (attached) also requires that no surface facilities are to be located on this property. The deed states "This deed is subject to "No Surface Occupancy" and it is agreed and understood that Grantee, its successors or assigns shall not be allowed access to the surface, nor shall Grantee conduct any operations or locate any facilities on the surface of the subject lands. Grantee shall be entitled to all other mineral rights associated with oil and gas development, including the ability to participate in and receive royalty payments from the drilling of directional or horizontal wellbores." The abandoned wells would be cutoff after mining has reached the bedrock surface or the reclaimed slope surface where a new cap and any additional concrete for the existing plug would be needed. McCarty Engineering, LLC has provided this service for J-2 Contracting and at other mining permit locations for other operators. They are licensed and bonded to obtain approvals from the COGCC to do these types of re -plug services on abandoned oil and gas wells. Products Sand and gravel will be the primary product produced from the Sunset Industrial Pit. The principal intended use for the sand and gravel is for road base and construction aggregates. Subsurface drilling and testing have verified that the Sunset Industrial Pit property contains a significant commercial deposit of sand and gravel. The depth of interbedded sandy clays and clayey to silty sands at the surface range from 0 to 14 feet. The thickness of the aggregate material ranges from 40 to 107 feet where bedrock contact occurs. Mining Methods The deposit will be dry mined and slurry walls will be constructed around the perimeter of the mining area for Phases 1 and 2. The intent is to mine the upper portion of the phases within 3 to 4 feet of the anticipated high groundwater prior to installation of the slurry walls. Mining will not expose groundwater prior to the slurry wall being constructed around each phase. Design specifications for the slurry wall and quality control procedures used during construction will ensure that the reclaimed reservoir meets State Engineer's Office (SEO) performance standards. Dewatering trenches will be excavated around the perimeter of each mining area prior to mining operations commencing. The depth of the ditches will vary as the mining progresses deeper into the alluvium in order to maintain the groundwater level below the active sillJ&T Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application mining bottom surface, and therefore minimize the exposed groundwater surface area. The dewatering ditches will flow to a collection pond, from which the water will be pumped and discharged into recharge areas where overflow will reach a culvert that crosses 8th Street into the Ogilvy Ditch and ultimately reach the Cache La Poudre River. The equipment and facilities may include, but are not limited to the following: Processing Equipment Screens, wash plant, crusher, conveyors, stackers, and other miscellaneous processing equipment. Earth Moving Equipment Dozers, loaders, scrapers, excavators, and compactors will be used for mining and earth moving operations. Miscellaneous Equipment Dewatering pumps, electrical trailer, generator trailer, small portable generators and watering trucks will be used as needed. As mining progresses, topsoil and overburden will be stripped to expose the aggregate product below. All soil and overburden material will be used on -site for reclamation; so long-term stockpiling of these materials is not anticipated. Overburden stockpiles will be located within the proposed mining area. The stockpiles will be placed parallel to the floodplain to mitigate impacts to the floodplain. Mining of the aggregate will progress down to the underlying bedrock. Since reclamation will occur concurrently with mining, it is not anticipated that overburden material will be stockpiled long-term prior to use in production of road base. During mining the mining face for Phases 1 and 2 will have a 3H:1V slope to bedrock or the bottom of the future reclaimed reservoir. The processed aggregate material will be temporarily stockpiled near the portable processing plant. Recommendations for monitoring of slope stability, including, conducting a visual inspection of the excavated slopes on a weekly basis for the duration of mining, conducting a visual inspection after a major precipitation event that has saturated the ground using the same procedures, contacting qualified personnel to evaluate and recommend remediation work to stabilize the area in the event a visual inspection detects signs of potential slope failure, and if no visible signs of slope failure are detected during mining, reducing visual inspections to once every six months after mining completion, or after every major precipitation event. All local, State, and Federal rules and regulations will be followed for the storage and handling of any fuel for the facilities. Topsoil Handling Plan As stated previously the topsoil will be stripped to expose the aggregate product underlying the topsoil. The topsoil will be stripped using scrapers and stockpiled in the topsoil stockpile as depicted in Exhibit C. The volume of topsoil for all the mining phases is approximately 115,000 cubic yards. The depth of the topsoil is approximately twelve inches over the majority of the mining area. The topsoil will be stripped and stockpiled during each phase of mining where topsoil will only be removed for Phase 1 and Phase 2 as they are going to be mined. The height of the topsoil stockpile will be approximately 15 feet. J tT Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application Mine Phasing J-2 Contracting anticipates mining and reclaiming the Sunset Industrial Pit in 4 phases, progressing through the phases starting with Phase la, Phase 1, Phase 2a, and then Phase 2 as shown on the Mining Plan Map. The overall time required to complete the mining and reclamation is estimated to be 12 years 10.5 months based on an average rate of 650,000 tons per year. The initial production is expected to be 300,00 tons per year with the maximum production expected to be 1,000,000 tons per year. However, it is possible that due to demand fluctuations, mining could progress slower than anticipated and additional time may be required for mining and reclamation of the site. The operator is proposing to mine Phase la first. Phase la is 64.22 acres and the estimated time for mining Phase la is approximately 2 years and 11 months. After completion of Phase la, and prior to the mining Phase 1, a slurry wall will be installed around the perimeter of Phase 1 prior to exposing groundwater. Phase 1 is 64.22 acres. The estimated time for mining Phase 1 is approximately 7 years and 2 months. The operator is proposing to mine Phase 2a third as the area is currently being permitted as an RV storage site so this area will not be mined until after Phase 1. The estimated timing for mining Phase 2a is approximately 1 year and 7.5 months. After completion of Phase 2a and prior to the mining Phase 2 a slurry wall will be installed around the perimeter of Phase 2 prior to exposing groundwater. Phase 2 is 20.95 acres. The estimated time for mining Phase 2 is approximately 1 year and 2 months. The mining will progress in each phase beginning at the outer edge of the phase where material will be moved toward the interior of the phase such that the mining slope can be established. The mining slope will be established for the entire perimeter of the phase in 3 to 6 feet intervals. Dewateri ng Dewatering trenches will be placed along the perimeter of each mining area in Phases 1 and 2. The dewatering trench around the perimeter of the phase being mined will be placed at the toe of the mining slope. As the phase is mined deeper the dewatering trench will be lowered and moved laterally along the mining slope toward the center of that phase. Slurry walls are anticipated to be installed around the perimeter of Phases 1 and 2 prior to exposing groundwater and mining will continue to commence in those phases and it is expected minimal dewatering will be required after the slurry walls are installed due to the slurry walls cutting off groundwater infiltration into the pit. J-2 Contracting Company will have an approved substitute water supply plan and well permit prior to exposing groundwater. The substitute supply plan will be updated annually to account for water that is consumed due to exposing groundwater by the mining operation. Explosives Explosives will not be used during mining. hid I J .T Consulting, Inc.

Further west is the Arc Industrial Business Park Subdivision, zoned 1-3 (Heavy Industrial), and lands to the north and east have been annexed into the City of Greeley and are associated with the Greeley -Weld County Airport Authority operations. Lands located south of East 8th Street are zoned 1-3 (Heavy Industrial) and utilized as a residence with lands surrounding a five (5) -acre parcel, annexed into the City of Greeley and utilized by the Bliss Produce Company. Industrial use of this property is in harmony with the majority of the surrounding land uses. c. Section 22-2-40.A states: "Support compatible economic development opportunities." The site is located within a Weld County Opportunity Zone on the Comprehensive Plan Map and is in an industrial area, thus encouraging the agglomeration of synergistic businesses. B. Section 23-2-40.6.2 — The uses which will be allowed on the subject property by granting the Change Of Zone will be compatible with the surrounding land uses. Surrounding land is being used commercially. Notice was sent to 112 surrounding properties and no responses were received. The City of Greeley referral, dated November 22, 2022, contained o nly advisory comments for future development and no concerns with the present request. Per the referral, the subject site is located within the City of Greeley's Long Range Expected Growth Area (LREGA) and if annexed into the City of Greeley, any development would be required to follow the Municipal Code criteria. The Greeley Land Use Guidance Map (2017) designates the area as the Northeast Industrial Area for future industrial development land uses. The City of Evans expressed no concerns in the November 8, 2022, referral as it is outside the City of Evans Future Land Use Map area, and the Town of Kersey expressed no concerns in their referral, dated November 8, 2022. The Town of Garden City did not respond to the referral, and the City of Greeley Fire Department also expressed no concerns in their referral, dated November 8, 2022. Future industrial uses will have to be approved through a Site Plan Review o r Use by Special Review process. Site Plan Review and Use by Special Review applications are sent to referral agencies for comments. The Conditions of Approval and Development Standards applied to both this Change of Zone and any future Site Plan Reviews will adequately address and mitigate potential impacts. Due to the proximity of other industrial o perations in the vicinity, a Change of Zone to 1-3 (Heavy Industrial) is compatible with the surrounding land uses. 4889183 Pages: 2 of 10 03/29/2023 10:15 AM R Fee:$0.0® Carly Koppes, Clerk and Recorder, Weld County , CO �IIIkI�1R�1N�+l�h'hail'�VL+l�{t16+�{R�tflYi�h��YY4� �IIII 2023-0614 PL2860 CHANGE OF ZONE (COZ22-0012) - SUNSET INDUSTRIAL, LLC PAGE 3 C. Section 23-2-40.B.3 -- Adequate water and sewer service can be made available to the site to serve the uses permitted within the proposed zone district. The existing residence is currently served with domestic water from the NWCWD, via account #2184003 and an On -site Wastewater Treatment System (OWTS). The existing OVVTS, which is not currently permitted/documented through the Weld County Department of Public Health and Environment, will require an OWTS Evaluation prior to the issuance of the required permit/documentation. In the event the system is found to be inadequate, the system must be brought into compliance with current OWTS regulations, as expressed by the Department of Public Health and Environment in the November 20, 2022, referral response. The City of Greeley in their November 22, 2022, referral stated if in the future, water and sanitary sewer services are requested to serve the property, annexation into the City of Greeley will be required prior to the City of Greeley providing those utility services, as the City of Greeley does not currently provide utility services to the subject property. The NWCWD did not respond to the referral request. Section 24-1-40 of the Weld County Code states "Urban -scale commercial and industrial developments require public or private sewer systems (On -site Wastewater Treatment Systems)." D Section 23-2-40.B.4 — Street or highway facilities providing access to the property are adequate in size to meet the requirements of the proposed zone districts. 1) Section 23-3-330 of the Weld County Code states: "Properties zoned 1-3 should be located near transportation infrastructure such as highways, railroads, or airports." East 8th Street is designated on the 2011 Greeley Transportation Plan as a minor arterial and a collector road on the Weld County Functional Classification Map (2020). The Weld County Development Review referral, dated November 15, 2022, indicated, per Section 23-2-30.A.4 of the Weld County Code, paved roadways are considered adequate in functional classification, width and structural capacity to meet the traffic requirements of the Change of Zone. The City of Greeley Real Estate Management Department commented on a parcel acquired for right-of-way that is adjacent to the property in review here. The City of Greeley is currently working with a surveyor to obtain the necessary legal descriptions and recording the documents to create future right-of-way and not a separate legal parcel. E. Section 23-2-40.B.5 — In those instances where the following characteristics are applicable to the rezoning request, the applicant has demonstrated compliance with the applicable standards: 1) Section 23-2-40.B.5.a — If the proposed Change of Zone is located within any Overlay District identified by maps officially adopted by the County, that the applicant has demonstrated compliance with 4889183 Pages: 3 of 10 03/29/2023 10:15 AM R Fee:$0.00 Carly Koppes, Clerk and Recorder, Weld County , CO 11111 111 2023-0614 PL2860 CHANGE OF ZONE (COZ22-0012) -- SUNSET INDUSTRIAL, LLC PAGE 4 the County regulations concerning Overlay Districts. Compliance may be demonstrated in a previous public hearing or in the hearing concerning the rezoning application. The site is located within the A -P (Airport) Overlay District. Development of the site will be required to comply with applicable requirements in Chapter 23, Article V, Division 1, of the Weld County Code. The Greeley -Weld County Airport Authority did not respond to the request for comment. Future development applications will be sent to the airport for review. The site is also located in the Floodplain Management Overlay District. Development of the site will be required to comply with applicable requirements in Chapter 23, Article XI of the Weld County Code.

Ross Lori Saine 2023-0614 PL2860 EXHIBIT E Reclamation Plan Lined water storage reservoirs will be the final reclaimed use for the Sunset Industrial Pit. Portions of mining areas will be reclaimed as "native" areas, which will be re -seeded with native vegetation. The majority of the mining areas will be reclaimed as water storage reservoirs. The remaining area within the proposed permit boundary will consist of reservoir shoreline, unimproved access roads around the reservoirs, and reclaimed vegetated land. Final Land Use Reclamation Plan Area (acres) Reservoir Water Surface 53.60 Access Roads 9.70 Reclaimed and Slopes Vegetated above Reservoir Land (Disturbed Water Surface) Land 21.87 TOTAL 85.17 Water Storage Reservoir In general, the mining limits will be mined down to the shale/claystone/sandstone bedrock. The relatively impermeable bedrock will make the bottom of the reservoir. The reservoir will be separated from the surrounding alluvial aquifer by the slurry wall liner system as detailed in the cross-section shown on the Reclamation Plan Map. The slurry wall liner will be keyed into the bedrock material and extend upward through the height of the alluvium at the bench depicted in the mining plan. A clay liner will be installed above the slurry wall to complete the liner design/construction from the bench elevation to three feet above the reclaimed normal water surface elevation. Design specifications and quality control procedures used during the construction of the slurry wall liner and clay liner will ensure that the reservoir meets the State Engineer's Office (SEO) performance standards for permeability. All reservoir slopes will be reclaimed to at least 3H:1 V final grade Since reclamation will be concurrent with mining, most soil, overburden, and bedrock material excavated during mining will be used almost immediately. Scrapers and dozers and compactors will be used to shape the reclaimed slope material along the reservoir perimeters to achieve the final grade. Upon placing the backfill material, 95 percent compaction will be achieved to ensure adequate integrity of the clay liner above the bench, backfilled areas for haul/access roads and recharge pond areas that are not within the future water storage/reservoir footprint. Final reclamation by capping with topsoil and re -vegetating above the expected reservoir water level will follow grading operations as well as backfilled areas that will not be haul/access roads to minimize the amount of disturbance at any one time. Recommendations for monitoring of slope stability, including, conducting a visual inspection of the excavated slopes on a weekly basis for the duration of mining, conducting a visual inspection after a major precipitation event that has saturated the ground using the same procedures, contacting qualified personnel to evaluate and recommend remediation work to stabilize the area in the event a visual inspection detects signs of potential slope failure, and if sill J T Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application no visible signs of slope failure are detected during mining, reducing visual inspections to once every six months after mining completion, or after every major precipitation event. During reclamation activities, inlet and outlet facilities for the reservoir will be designed and installed once the operational criteria of the proposed reservoir have been identified by an end user. Reclamation Measures/Materials Handling Backfilling will be done to provide stabilized shorelines around the reservoir and to minimize erosion. The backfill material will consist of gravel, overburden, clay, and topsoil. There will not be known toxic or hazardous materials in the backfill material. Additionally, it is not likely that acid forming or toxic materials will be encountered during mining. The mining will not leave high walls on the property. In addition, there will be no auger holes, excavations, or shafts left on the property. Topsoil will be placed to finalize the grading such that seeding can occur. The topsoil will be placed at all disturbed areas and on the mining slope to an elevation matching the expected reservoir water level. Topsoiling Approximately the top twelve inches of soil on the property is classified as topsoil. This layer includes the root zone of grasses and crops, which will be stripped and stockpiled separately. By using concurrent reclamation techniques, the topsoil is not expected to remain in stockpiles for more than one to five years. If the stockpile remains more than one growing season, it will be seeded with a fast-growing vegetative cover to prevent erosion. All topsoil will be retained on - site to reclaim the reservoir shoreline, and other areas disturbed by mining activities. Where required, topsoil will be replaced to a depth of twelve inches. Revegetation As mining operations are completed, areas for reclamation will be graded and shaped for revegetation. Runoff or excess water from adjacent areas will not be allowed to flow over slopes being graded and seeded. If needed, berms or channels will be constructed to divert excess water and convey it in a safe and non -erosive manner. For disturbed areas, the reclamation plan includes re -vegetating with appropriate seed mixes to minimize erosion and re-establish natural terrain. The seed mixture below was selected to be long lasting and regenerating, as recommended by the Greeley Natural Resource Conservation Service Office (see attached recommendation). The ground will be fine graded prior to seeding and mulch will be applied according to recommendations from the NRCS. Reservoir side slopes below the anticipated reservoir water level will not be seeded. The proposed seed mix is shown in the following table. LinJa6T Consulting, Inc.

The seeded areas will be covered with dead crop litter from sorghum or milo crop forage, or with straw mulch at a rate of 4,000 pounds per acre. If a significant invasion of noxious weeds occurs after seeding, the weeds will be mowed before they can go to seed. The areas will be mowed periodically for additional control as needed. Mechanical control will be used as a first priority. Chemical methods will only be used if no other alternative produces acceptable results. For temporary earthen stockpiles, the reclamation plan includes re -vegetating with appropriate seed mixes to minimize erosion and establish more rapidly to stabilize the stockpiles. If a temporary earthen stockpile remains more than one growing season, it will be seeded with the seed mix below to prevent erosion.

The proposed mitigation efforts to minimize these impacts are recharge ponds or ditches in necessary areas to maintain groundwater levels during the mining, and a perimeter drain if needed to convey groundwater around the lined reservoir after the pit side liner is installed. A ground water model by McGrane Water Engineering, LLC has also been provided and the results indicate that water levels will be affected by +1-1 ft and there are not any wells within the predicted water level change so the overall impact of the slurry wall and clay liner will be insignificant. J-2 Contracting Company proposes that they monitor groundwater levels through both interior (within phases of the mining) and exterior (outside the slurry wall lining) monitoring wells that they have installed, or have access to before, during, and after the mining and reclamation is complete so that impacts to the groundwater table, from this mining operation, can be identified and addressed. It is the intent of J-2 Contracting Company to operate responsibly and to mitigate any damage to wells that is directly attributable to the mining and reclamation of this site. Reclamation — Approximate Time Table The initial proposed rate of production for the mine is 300,000 tons per year and the maximum proposed rate of production for the mine is 1,000,000 tons per year. The total time frame to mine all phases assuming an average production rate of 650,000 tons per year is approximately 12 years and 10.5 months. The following table shows the approximate time frame to finish each phase of mining assuming an average production rate of 650,000 tons per year: Mine Phase and Acrea a g Time Frame Reclaim to Complete Phase and Phase la — 64.22 acres 2 years and 11 months Phase 1 — 64.22 acres 7 years and 2 months Phase 2a — 20.95 acres 1 year and 7.5 months Phase 2 — 20.95 acres 1 year and 2 months The assumed annual production rate is 300,000 tons initially to 1,000,000 tons maximum for processed material leaving the mine each year. The size and area of reclamation varies for each phase but generally consists of the outside mining slope in phases 1 a, 1, 2a, and 2 being reclaimed at a 3H:1V slope with the addition of clay, overburden, topsoil, and revegetation. For more information on sequencing and size of the reclamation activities refer to Exhibit L financial warranty calculations. J&T Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application EXHIBIT G Water Information Introduction The Sunset Industrial Pit mining site is located in the E 1/2 of NW 1/4, the NE 1/4 of the SW 1/4, the E 1/2 of the SW 1/4 of the NW 1/4, and the E 1/2 of the NW 1/4 of the SW 1/4 of Section 3, Township 5 North, Range 65 West of the 6th Principal Meridian, County of Weld, State of Colorado and that part of the SE 1/4 of the SW 1/4 and the E 1/2 of the SW 1/4 of the SW 1/4 of Section 3, Township 5 North, Range 65 West of the 6th Principal Meridian, County of Weld, State of Colorado lying North of the Eighth Street Road except that portion described in deed recorded September 24, 1982, at reception no. 1904628, Weld County, Colorado. The proposed mining site is adjacent to the City of Greeley city limits, and adjacent to 8th Street. The Cache La Poudre River is approximately 700 feet south of the site on the south side of the permit boundary. 8th Street is immediately adjacent to the south side of the permit boundary. Access to the site will be located at the southwest corner of the permit boundary off of 8th Street. The operation will consist of sand and gravel production and will impact the Cache La Poudre River in the form of depletions due to evaporation and operational losses associated with mining. Mining of the Sunset Industrial Pit mining site will last for approximately 12 years. Once reclamation is complete reservoirs will be created with a total surface area of Reservoir 1 being 41.89 acres and Reservoir 2 11.71 acres. The depth to groundwater ranges from 18 to 40 feet within the permit boundary (measured in MW -1 through MW -5, See the attached piezometer measurements table). The site will be mined down to a depth of 40 to 112 feet thus exposing groundwater to the atmosphere. This exposed groundwater, along with the operational losses associated with the extraction of sand and gravel deposits, will impact the Cache La Poudre alluvial aquifer. These impacts will cause river depletions that must be augmented. Groundwater will be exposed during the mining once the mining depths reach an elevation of approximately 4614. To enable dry mining at the Sunset Industrial Pit mining site, there will be dewatering trenches around the various phases of the site. These dewatering trenches will change in length throughout mining. The maximum length will occur when one phase is completely mined, but before the reclamation has begun on any given phase. The maximum size of dewatering trench will be 3,000 feet long and 5 feet wide, or 0.33 acres of exposed surface area. This water will be collected in a recharge pond totaling 3.5 acres. The water will be pumped into dewatering ditch, which traverses the site, into a recharge pond and ultimately into the Cache La Poudre River. As mining progresses, the dewatering trenches will shift as various cells are reclaimed. The gravel pit will have a slurry wall liner being constructed as mining commences in Phase 1. Water Requirements Water use at the Sunset Industrial Pit mining site will include evaporation from exposed groundwater, dust control of haul roads and stockpiles, and water retained in material removed from the site. J tT Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application Evaporative Loss Evaporative losses are dependent on the exposed water surface area, which may shift throughout the mining operation, but will not exceed the maximum. Exposed surface area at the Sunset Industrial Pit mining site will include groundwater exposed in the dewatering trenches and recharge pond. The maximum exposed surface area at the site during mining is estimated at 3.83 acres. J-2 Contracting Company plans to keep the site dewatered throughout the life of the mine. Evaporation data was taken from NOAA Technical Report NWS 33, Evaporation Atlas for the 48 Contiguous United States. The annual gross evaporation was determined to be 45 inches for this location. Monthly evaporation percentages are established by guidelines set by the State Engineer's Office. To determine precipitation, data from the National Weather Service for Greeley, CO (UNC) (1967-2022) was used. The long-term average precipitation at the Sunset Industrial Pit mining site is estimated at 14.69 inches. Effective precipitation is calculated as 70% of the total precipitation. The net evaporation is the difference between gross annual evaporation and effective precipitation. The resulting net evaporation is 2.52 feet. The maximum evaporative loss from the 3.83 acres is 9.67 ac -ft. Operational Loss The average annual production from the Sunset Industrial Pit mining site is estimated at 650,000 tons. Using 4% moisture content, the total associated consumptive use for water retained in the material mined is 19.95 ac -ft. Dust control use is 10,000 gal/day, 6 days/week, 4 weeks/month for 10 months of the year. This equates to 7.4 ac -ft. Maximum annual operational loss is estimated to be 27.35 ac -ft for Phase 1. Consumptive Use The maximum annual consumptive use (operational loss + evaporation loss) at this site during the mining operation is estimated to be 37.02 ac -ft for Phase 1. Replacement Water The replacement of consumptive uses at the site is will be accounted for in a substitute water supply plan (SWSP) approved by the State Engineer. The SWSP will be obtained prior to any mining activities occurring that expose groundwater. Surrounding Water Rights The attached Figure A-1 Well Permits in the Sunset Industrial Pit — Groundwater Evaluation by McGrane Engineering, LLC shows the permitted wells within 600 feet of the mining limits and permitted wells within the boundaries of the groundwater model/evaluation. The well information and locations were obtained from the Division of Water Resources online mapping well permit locator. This well and water rights information was cross checked with the State's CDSS. J&T Consulting, Inc.

If the proposed use of groundwater at the Sunset Industrial Pit mining site results in material injury to surrounding wells, J-2 Contracting Company will ensure that all necessary measures are taken to address the issues. Water Quality An NPDES permit will be obtained from the Water Quality Control Division at the Colorado Department of Public Health & Environment for the Sunset Industrial Pit mining site prior to discharging any groundwater that is dewatered from the site. This permit will be kept current and amended as necessary to ensure that any water discharged from the site will meet the permitted water quality standards. Impacts to Groundwater/Hydrologic Balance J-2 Contracting Company will monitor the groundwater levels surrounding the site and provide groundwater recharge if necessary via perimeter ditches/ponds. J-2 Contracting Company will construct these ditches/ponds in the locations where direct discharge to an existing adjacent irrigation lateral is not available to ensure that stabilized groundwater levels are maintained. They will discharge dewatering flows into existing adjacent irrigation laterals where possible to limit the disturbance to the surrounding land. Slurry wall liners are proposed around the individual phases and will likely be installed either shortly after mining has begun or prior to mining starting. Ja6T Consulting, Inc. J-2 Contracting Company Sunset Industrial Pit DRMS 112 Permit Application To summarize the mitigation process, as each phase of mining/dewatering occurs, J-2 Contracting Company will monitor the groundwater levels adjacent to mine as each phase progresses. If groundwater levels drop to a level that prevents an adjacent well from performing acceptably, according to that well's owner, J-2 Contracting Company will either implement a groundwater recharge ditch/pond near the well in order to raise the groundwater level in the vicinity of the well and hence return it's operation to acceptable standards, or will negotiate an agreement with that well owner to replace the well or provide replacement water via other means until the mining and reclamation activities are concluded but it is not anticipated that any groundwater levels will drop since the slurry wall for each phase will be installed prior to exposing groundwater. Groundwater wells that are not owned by J-2 Contracting Company or Sunset Industrial, LLC (Table G-1) are potentially located within 600 feet of the mining limits. The exact physical location of these wells will be determined during the SWSP and well permit application processes. If wells are found to be within 600 feet of the mining limits, J-2 Contracting Company will either obtain a well waiver from the owner of the well, or provide an agreement with the well owner that J-2 Contracting Company will mitigate and material damage to the well that is directly attributable to the mining and reclamation of the site. All other wells within 600 feet of the mining limits are either owned by Sunset Industrial, LLC, or are monitoring wells therefore groundwater impacts to these wells do not need to be addressed. See the attached Piezometer Location Map, and Piezometer Data Summary, which show the locations of monitoring wells around the perimeter of the site that J-2 Contracting Company/Sunset Industrial, LLC has either installed or has access to, and the groundwater level data that has been collected for each well.

The map unit descriptions in this report, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named, soils that are similar to the named components, and some minor components that differ in use and management from the major soils. Most of the soils similar to the major components have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Some minor components, however, have properties and behavior characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. __ Natural Resources Web Soil Survey Conservation Service National Cooperative Soil Survey 4/17/2023 Page 1 of 9 Map Unit Description ---Weld County, Colorado, Southern Part Sunset Undustrial Soils that have profiles that are almost alike make up a soil series. All the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of a given series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. Additional information about the map units described in this report is available in other soil reports, which give properties of the soils and the limitations, capabilities, and potentials for many uses. Also, the narratives that accompany the soil reports define some of the properties included in the map unit descriptions.

Any alteration or modification of this form, without approval by the Board shall result in the financial warranty being invalid and result in the voiding of any permit issued in conjunction with such invalid financial warranty and subject the operator to cease and desist orders and civil penalties for operating without a permit pursuant to sections 34-32-123, C.R.S., of the Mined Land Reclamation Act and 34- 32.5423, CRS., of the Colorado Land Reclamation Act for the Extraction of Construction Materials. KNOW ALL MEN BY THESE PRESENTS, THAT: WHEREAS, the Colorado Mined Land Reclamation Act, C.R.S. 1973, 34-32-101 et seq. (the "Act"), as amended, provides that no permit may be issued under the Act until the Mined Land Reclamation Board (the "Board") receives a Financial Warranty (or Warranties) as described in the Act. WHEREAS, J-2 Contracting Company (the "Operator"), a Colorado corporation, has applied for a permit to conduct a mining operation known as Sunset Industrial Pit (the "Operation"), on certain lands in Weld County, Colorado. These lands are described in the permit application, as amended and supplemented, and are referred to herein as the "Affected Lands". 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us John W. Hickenlooper, Governor I Robert W. Randall, Executive Director w Virginia Brannon, Director 'A 7'{ WHEREAS, in the application for the permit, the Operator has agreed to be bound by all requirements of the Act and all applicable rules and regulations of the Board, as amended from time to time. WHEREAS, in the application for the permit, the Operator has agreed with the Board to provide for reclamation of the Affected Lands that are now, or may become, subject to the permit, as required by law. WHEREAS, the Operator and Amerisure Mutual Insurance Company (the "Warrantor"), a corporation organized and existing under the laws of the State of Michigan and duly authorized to transact a bonding and surety business in the State of Colorado are hereby and firmly bound unto the State in the sum of Two Hundred Fifty -Tv Tl Tareun Hundred Seventy Nine WA N&loofl Dollars ($ $252,379.00 ) for the life of mine or until such time as replacement is received, for the payment of which sum, well and truly made, we hereby bind ourselves and our personal representatives, successors and assigns, jointly and severally, firmly by these presents. WHEREAS, the Board has determined, in accordance with the Act, that the estimated costs of reclamation of the Affected Lands are those amounts for the stated periods of time as set forth herein. Said amount may be amended from time to time to reflect revised estimates of said costs of reclamation. WHEREAS, the Operator and the Warrantor, in accordance with the Act, has promised and hereby promises the Board that it will be responsible for all the estimated costs of reclamation with regard to the Affected Lands. WHEREAS, the Board has determined that this Financial Warranty by the Warrantor equals the estimated costs of reclamation, as approved by the Board, with regard to the Affected Lands. NOW, THEREFORE, the Operator and the Warrantor are held hereby firmly unto the State of Colorado in the amount of those sums for those periods of time as set forth herein, until this Financial Warranty is amended or released in accordance with applicable law. The Board may, for good cause shown, increase or decrease the amount and duration of this Financial Warranty. The Operator shall have sixty (60) days after the date of notice of any such adjustment to increase the surety amount, but no such increase shall bind the Warrantor unless and until it shall have consented thereto in writing by the issuance of an additional Financial Warranty or by an endorsement to this Financial Warranty. The Operator and the Warrantor shall notify the Board immediately of any event which may impair this Financial Warranty. If the Board receives such notice, or otherwise has reason to believe that this Financial Warranty has been materially impaired, it may convene a hearing in accordance with the Act for the purpose of determining whether impairment has occurred. The obligation of the Operator and the Warrantor shall continue until the Board has released this Financial Warranty or has ordered it forfeited in accordance with applicable provisions of the Act. It is understood that periods of years may necessarily be required before determination can be made that reclamation of the Affected Lands has been satisfactorily completed. It is also recognized that, as reclamation is accomplished, the amount of this Financial Warranty may be reduced with the approval of the Board so that it reflects the then current estimated cost of the remaining reclamation of the Affected Lands. No revision, extension, or renewal of the permit, or of the time allowed to complete reclamation, shall diminish the operator's or Warrantor's obligation under this Financial Warranty. No misrepresentation by the Operator which may have induced the Warrantor to execute this Financial Warranty shall be any defense to demand by the State under this agreement. Page 2 of 6 In any single year during the life of the permit, the amount of the Financial Warranty shall not exceed the estimated cost of fully reclaiming all lands to be affected in said year, plus all lands affected in previous permit years and not yet fully reclaimed. Reclamation costs shall be computed with reference to current reclamation costs. The amount of this Financial Warranty is based upon estimates as to the cost of reclamation, and does not operate to liquidate, limit, enlarge or restrict the Operator's obligations to complete reclamation and to comply in all respects with the permit and with applicable laws and regulations governing reclamation, even though the actual cost thereof may substantially exceed the amount of this Financial Warranty. The Mined Land Reclamation Board or the Office of Mined Land Reclamation may recover the necessary costs, including attorney's fees or fees incurred in foreclosing on or realizing the collateral used in the event this Financial Warranty is forfeited. The face amount ofthis Financial Warranty shall be increased by five hundred dollars ($500.00) to cover these costs. The Warrantor shall not be liable under this Financial Warranty for an amount greater than the sum designated herein, unless increased by a later amendment to this Financial Warranty. This Financial Warranty shall be reviewed by the Board from time to time, and the Board may require an increase in the principal sum of this Financial Warranty (and a corresponding increase in the surety amount) to cover increases in the estimated costs of reclamation, but no such increase shall bind the Warrantor unless and until it shall have consented thereto in writing by the issuance of an additional Financial Warranty or by an endorsement to this Financial Warranty. The Warrantor reserves the right to cancel this Financial Warranty, effective only upon an anniversary date, and only by giving written notice to that effect, mailed by Certified Mail, at least ninety (90) days prior to such anniversary date, addressed to both the Operator at its address herein stated, and to the Board at the address herein stated. In the event of such cancellation, this Financial Warranty shall nevertheless remain in full force and effect as respects the reclamation of all areas disturbed prior to the effective date of such cancellation, unless and until the Operator shall file a substitute Financial Warranty which: (1) assumes liability for all reclamation obligations which shall have arisen at any time while this Financial Warranty is in force; and (2) is accepted in writing by the Board. In the event of such cancellation, if the Financial Warranty is not fully released, the amount of the continuing Financial Warranty available for the reclamation of areas disturbed and unreclaimed at the date of cancellation shall be fixed by the Board at the amount it determines necessary to complete such reclamation (which amount may not exceed the sum designated herein) and the Board shall concurrently identify such areas in writing, and notify the Warrantor and the Operator thereof. Thereafter, the obligation of the Warrantor shall be limited to reclamation of the areas so identified. The consideration for the Warrantor's execution of this agreement is the promise of the Operator to pay the premiums, but failure by the Operator to pay such premiums shall not invalidate or diminish the Warrantor's obligation hereunder. The Board may make demand upon the Warrantor for payment hereunder if the Board determines that reclamation which ought to have been performed by the Operator, or its successors or assigns, remains unperformed, and if Financial Warranty forfeiture procedures required by law have been initiated. No other condition precedent need be fulfilled to entitle the State to receive the amount so demanded. However, if, upon completion of reclamation by the State, the amounts expended for reclamation shall be less than the amount received from the Warrantor, the excess shall be promptly refunded to the Warrantor. If demand is made upon the Warrantor for payment of an amount due to the Board hereunder, and if the Warrantor fails to make payment of such amount within ninety (90) days after the date of receipt of such demand, or if it should thereafter be determined, by agreement of the Warrantor or by final judgment of court, that the amount demanded was properly payable, the Warrantor agrees to pay to the Board, in addition to the amount demanded, interest at the Page 3 of 6 current published Wall Street Journal Prime Rate for the period commencing at the end of such ninety -day period and ending on the date of actual payment. If the Board shall notify the Warrantor that the Operator is in default, and if the Board shall initiate any Financial Warranty forfeiture procedures required by law or regulation, the Warrantor may, in lieu of making payment to the Board of the amount due hereunder, cause the reclamation to be timely performed in accordance with all requirements of the Act and all applicable rules and regulations. In such event, when and if the reclamation has been timely performed to the satisfaction of the Board or Division, this Financial Warranty shall be released. If the reclamation shall not be so performed to the satisfaction of the Board or Division, this Financial Warranty shall remain in full force and effect. This Financial Warranty shall be subject to forfeiture whenever the Board determines that any one or more of the following circumstances exist: I. A Cease and Desist Order entered pursuant to Section 34-32-124 of the Act has been violated, and the corrective action proposed in such Order has not been completed, although ample time to have done so has elapsed; or 2. The Operator is in default under its Performance Warranty, and such default has not been cured, although written notice and ample time to cure such default has been given; or 3.
