Principal Meridian, in Weld County, Colorado. The proposed mining site is located within the Town of Milliken. CR 46 is north of the property and an access road from the property connects to CR 46 near the intersection of CR 46 and CR 25. The South Platte River is adjacent to the property and approximately 880 feet south of the site on the south side of the permit boundary and 140 feet from the east side of the permit boundary. The dominant land use surrounding the property is agricultural use and industrial use. An aggregate processing plant will be located in Phase 1. These areas will contain stockpiles, portable equipment, storage bins, and silos as necessary to support the plant operations. Mining will start from the northeast corner of the mining limit then moving south approximately to one third of the property then west, then moving south to another third of the property back to the east, then moving south to the final third of the property to the west to complete mining and reclamation. All local, State, and Federal rules and regulations will be followed for the storage and handling of any petroleum products. The permit boundary will encompass approximately 111.01 acres which will all be affected acreage, and approximately 98.24 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) 98.24 Mined Area Access Roads 2.36 Disturbed Land 10.41 TOTAL 111.01 Various setbacks from adjacent roads, adjacent structures, and oil and gas infrastructure will be maintained as mining occurs. 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 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. Petroleum Development Corporation (PDC) is the leaseholder and operator of the existing abandoned wells. Discussions with PDC have indicated they would cut down the existing casings as mining occurs. We have also worked with McCarty Engineering, LLC to provide this service at other mining permit locations for other operators. If PDC does not want to perform this work then McCarty Engineering, LLC would be contacted to do it. They are 41.1 JET Consulting, Inc. IHC Sc* Inc. Bernhardt Sand and Gravel Pit DRMS 112 Permit Application 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 Bernhardt Sand and Gravel 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 Bernhardt Sand and Gravel Pit property contains a significant commercial deposit of sand and gravel. The depth of clay, interbedded sandy clays and clayey to silty sands at the surface range from 1 to 8 feet. The thickness of the aggregate material ranges from 4 to 37 feet where bedrock contact occurs. Mining Methods The deposit will be dry mined and a slurry wall will be constructed around the perimeter of the mining area for Phase 1. Mining will not expose groundwater prior to the slurry wall being constructed around the perimeter of Phase 1. 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 ditch that flows to the South Platte 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 the slope reclamation and also the production of road base. During mining the mining face for Phase 1 will have a 2H:1V slope to bedrock or the bottom of the future reclaimed 41. J&T Consulting, Inc. 1HC Scott, Inc. Bernhardt Sand and Gravel Pit DRMS 112 Permit Application reservoir and the reclamation slope will be constructed using the excess overburden to a 4.5H:1 V slope. 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 failures 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 13,000 cubic yards. The depth of the topsoil is approximately six 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 as Phase 1 is mined. Mining will start from the northeast corner then moving south approximately to one third of the property then west, then moving south to another third of the property back to the east, then moving south to the final third of the property to the west to complete mining and reclamation. The height of the topsoil stockpile will be approximately 15 feet to 20 feet. Mine Phasing IHC Scott, Inc. anticipates mining and reclaiming the Bernhardt Sand and Gravel Pit in 1 phase, progressing through this phase as shown on the Mining Plan Map. The overall time required to complete the mining and reclamation is estimated to be 11 years 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. Phase 1 is 98.24 acres and the estimated time for mining Phase 1 is approximately 11 years. The mining will progress 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. Dewaterinq Dewatering trenches will be placed along the perimeter of Phase 1. 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. A slurry wall is anticipated to be installed around the perimeter of Phase 1 prior to exposing groundwater and mining will continue to commence and it is expected minimal dewatering will be required after the slurry wall is installed due to the slurry wall cutting EnJ&T Consulting, Inc. IHC Scott, Inc. Bernhardt Sand and Gravel Pit DRMS 112 Permit Application off groundwater infiltration into the pit. IHC Scott, Inc. 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. J&T Consulting, Inc. IHC Scott, Inc. Bernhardt Sand and Gravel Pit DRMS 112 Permit Application EXHIBIT E Reclamation Plan A lined water storage reservoir will be the final reclaimed use for the Bernhardt Sand and Gravel Pit. Portions of mining area will be reclaimed as "native" areas, which will be re -seeded with native vegetation. The majority of the mining areas will be reclaimed as a water storage reservoir. 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 92.35 Access Roads 3.59 Reclaimed Vegetated Land (Disturbed Land and Slopes above Reservoir Water Surface) 15.07 TOTAL 111.01 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 as depicted in the mining plan. Design specifications and quality control procedures used during the construction of the slurry wall 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 4.5H:1V 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 reclaimed slope, 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 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. jJ&T Consulting, Inc. NC Scott, Inc. Bernhardt Sand and Gravel Pit DRMS 112 Permit Application 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 as recommended by the DRMS for this climate zone (Dryland Quick Establishment, elevation less than 8,000 feet). Reservoir side slopes below the anticipated reservoir water level will not be seeded. The proposed seed mix is shown in the following table. jJ&T Consulting, Inc. IHC Scott, Inc.

If seed is to be broadcast, the application rate will be doubled. The seed mix for final reclamation as described above does not require fertilizer per the information provided by the DRMS. The seeded areas will be covered with dead crop litter from sorghum or milo crop forage, or with straw mulch at a rate of 2,000 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 above to prevent erosion. Water — General Requirement To minimize the effect on the prevailing hydrologic balance, IHC Scott, Inc. 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. 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 41.1 JET Consulting, Inc. IHC Scott, Inc. Bernhardt Sand and Gravel Pit DRMS 112 Permit Application 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 +/-0.5 to +/-1 ft and there are 5 wells (2 are owned by IHC Scott, Inc.) within the predicted water level change so the overall impact of the slurry wall and clay liner will be insignificant. IHC Scott, Inc. proposes that they monitor groundwater levels through both interior (within 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 IHC Scott, Inc. 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 — 98.24 acres 11 years 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 generally consists of the outside mining slope (mined at a 2H:1 V slope) in in Phase 1 being reclaimed at a 4.5H:1 V slope with the addition of clay, overburden, topsoil, and revegetation.

The proposed mining site is located within the Town of Milliken town limits. CR 46 is north of the property and an access road from the property connects to CR 46 near the intersection of CR 46 and CR 25. The South Platte River is adjacent to the property and approximately 880 feet south of the site on the south side of the permit boundary and 180 feet from the east side of the permit boundary. The operation will consist of sand and gravel production and will impact the South Platte River in the form of depletions due to evaporation and operational losses associated with mining. Mining of the Bernhardt Sand and Gravel Pit mining site will last for approximately 11 years. Once reclamation is complete a reservoir will be created with a total surface area being 92.35 acres. The depth to groundwater ranges from 3 to 7 feet seasonally 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 37 feet at the deepest depth 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 South Platte alluvial aquifer. These impacts will cause river depletions that must be augmented. Groundwater will be exposed during the mining once the miring depths reach an elevation of approximately 4713.8. To enable dry mining at the Bernhardt Sand and Gravel Pit mining site, there will be dewatering trenches around the perimeter of Phase 1. These dewatering trenches will change in length throughout mining. The maximum length will occur when Phase 1 is completely mined. The maximum size of dewatering trench will be 5,430 feet long and 5 feet wide, or 0.62 acres of exposed surface area. water will be pumped into dewatering ditch, which traverses the site, and ultimately into the South Platte River. As mining progresses, the dewatering trenches will shift as mining slopes 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 Bernhardt Sand and Gravel 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. 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 Bernhardt Sand and Gravel mining site will include groundwater exposed in the dewatering trenches. The VIII; UT Consulting, Inc. IHC Scott, Inc. Bernhardt Sand and Gravel Pit DRMS 112 Permit Application maximum exposed surface area at the site during mining is estimated at 1.80 acres. IHC Scott 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 Bernhardt Sand and Gravel Pit mining site is estimated at 14.26 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 2.56 feet. The maximum evaporative loss from the 1.80 acres is 4.61 ac -ft. Operational Loss The average annual production from the Bernhardt Sand and Gravel 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 19.13 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 26.53 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 31.14 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 Bernhardt Sand and Gravel 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. Between the sources, all permitted and decreed wells are included.

Bernhardt 500 Broad Street Milliken CO 80543 At the time of SWSP application/approval, a new gravel pit well permit will be applied for/obtained to include the evaporative and operational losses from the property. If the proposed use of groundwater at the Bernhardt Sand and Gravel Pit mining site results in material injury to surrounding wells, IHC Scott, Inc. 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 Bernhardt Sand and Gravel 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 IHC Scott, Inc. will monitor the groundwater levels surrounding the site and provide groundwater recharge if necessary via perimeter ditches/ponds. IHC Scott, Inc. will construct these J&T Consulting, Inc. IHC Scott, Inc. Bernhardt Sand and Gravel Pit DRMS 112 Permit Application 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. A slurry wall liner is proposed around the individual phase and will likely be installed prior to mining starting. To summarize the mitigation process, as each phase of mining/dewatering occurs, IHC Scott, Inc. 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, IHC Scott, Inc. 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 will be installed prior to exposing groundwater. Groundwater wells that are not owned by IHC Scott, Inc. (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, IHC Scott, Inc. will either obtain a well waiver from the owner of the well, or provide an agreement with the well owner that IHC Scott, Inc. will mitigate any 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 IHC Scott, Inc., 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 IHC Scott, Inc. has either installed or has access to, and the groundwater level data that has been collected for each well.

Lupton, CO 80621 RE: Bernhardt Pit — Groundwater Evaluation Dear Mr. York: Via email at: icyork@j-tconsulting.com The proposed Bernhardt gravel pit mine is located approximately 1 mile southeast of Milliken, Colorado in Section 24, Township 4 North, Range 67 West (6th PM). The site is located on the west bank of the South Platte River (SPR) which flows north at this location. Figure 1 shows the proposed pit boundary, groundwater model boundary and study area boundary that covers approximately 13 square miles. The model area is approximately 7 square miles. The study area includes approximately 224 permitted water wells per the State's well database (CDWR, 2023). Figures la, lb, lc, and ld include the well permits we used to help characterize the aquifer and identify wells that may be impacted. 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 Bernhardt pit. Impacts typically include a rise in the water table ("mounding") on the up -gradient side of the slurry wall and a decline in the water table ("shadowing") 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 home basements. A decline in water levels on the down gradient side could reduce the aquifer saturated thickness and well yields if the decline is more than approximately 10 percent of the saturated aquifer thickness. GROUNDWATER INVESTIGATION To evaluate the groundwater level changes in response to the slurry wall installation, we: 1. Conducted a literature search of existing published groundwater literature in the vicinity Milliken and Gilcrest, Colorado; 2. Compiled well data from the State's Well database (CDWR, 2023) including: well name, permit number, location, well depth, depth to water, and pumping rate (Table Al); 3. Updated maps prepared by the US Geological survey depicting the water table and alluvial aquifer bottom surfaces (aka bedrock structural elevation map) using more recent drilling data; 4. Compiled monitoring well data in Table A2 from monitoring wells drilled by Cesare, Inc during April 2023. 5. Created a MODFLOW groundwater model to evaluate changes in groundwater levels resulting from a slurry wall installed around the pit; and Bernhardt Pit Groundwater Evaluation May 2023 Page 2 of 31 6. Documented the data, our assumptions, results, a discussion of parameter uncertainty and model sensitivity and conclusions in Appendix A - Groundwater Evaluation and Modeling. Results Summary We used the USGS MODFLOW2000 (Harbaugh et al, 2000) modeling program to evaluate the existing and future groundwater conditions at the Bernhardt pit and the Groundwater Vistas (version 8) Groundwater Users Interface (GUI) to prepare model files and evaluate the results. Using reasonable boundary conditions and aquifer properties, the model predicts that water level changes of approximately +- 2.5 feet (Figure A10). Mounding greater than 0.5 feet extends approximately 1,500 feet up -gradient (south), and shadowing less than -0.5 feet can be expected approximately 2000 feet downgradient (north). There are five registered wells located within modeled change between +1- 0.5 to 1.0 ft as summarized in Table 1. Four of the wells are located in the mounding area on the up -gradient side of the pit and one well (13701-F) is located on the downgradient (shadow) side. Two of the four up -gradient wells belong to the Bernhardt's which are now owned by the applicant.

However, none of these wells none are located with the modeled mounding area. Conclusions and Recommendations We do not believe the Bernhardt Pit slurry wall will have any adverse effect on the wells identified in Table 1 because the modeled impacts are less than 1 foot, which is less than the seasonal groundwater change. Therefore, we do not expect any of the well owners within the area of change will notice any impacts. If they do, we recommend that ongoing monitoring occur to quantify those impacts.

The proposed pit and surrounding slurry wall are located approximately 200 feet west of the South Platte River (SPR). Figure 1 and la ld (located before Appendix A) show: the overall study area, model area, pit property, permitted wells color coded by use, well permit numbers and the Bernhardt pit private monitoring wells. Available Data We compiled hydrogeologic data from: • Existing reports from the US Geological Survey, Colorado Geological Survey and Colorado Division of Water Resources (see Sources below); • Permitted well "completion reports" filed with the State Engineer's Office ("SEO" wells) located within approximately 1.5 miles of the proposed pit; and • Four monitoring wells installed around the Bernhardt pit that were provided by J&T. Table Al includes well data from 224 registered wells extracted from the State's well database (CDWR, 2023). This includes 25 monitoring wells and 28 production wells that have been abandoned but still have useful information in the permit well completion report such depth to bedrock or well yield (these wells were not included in the impact evaluation). Most of the existing wells are used for domestic water supply, irrigation, monitoring or as stock wells. Compiled data includes: the permit number, well owner, Colorado State Plane coordinate, USGS Digital Elevation Model (DEM) elevation, registered use, well depth, depth to bedrock, yield in gallons per minute (gpm) and reported static water level (SWL). The depth to bedrock was documented if bedrock was identified in the well driller's "geologic" log. Well statistics are shown at the bottom Table Al. The well depth from 200 wells ranged from 5 to 98 ft and averaged 54 ft. The observed depth to bedrock from 92 wells ranges from 19 to 95 ft and averages 50 feet, 4 feet less than the average well depth. Well yields from 109 wells range from 5 gpm (domestic well) to 2,150 gpm for irrigation. The reported static water level depths for 134 wells ranges from 4 to 39 feet and averages 21 ft. Seasonal water level variability is discussed below. Table A2 shows monitoring well data for the four Bernhardt borehole monitoring wells. The wells were drilled by Cesare, Inc./CMT Technical Services in March, 2023. The depth to bedrock ranges from 33 to 40 ft which is approximately 10 feet less than the average (50 ft). This is because the pit is located along the western edge of the SPR alluvial aquifer at the bedrock contact with the Fox -Hills sandstone. The depth to water ranges from 4.42 ft to 8.0 ft which is much shallower than average (21 ft) due to the wells close proximity to the SPR. HYDROGEOLOGY The hydrogeology of the SPR alluvial aquifer is described in detail by the US Geological Survey (Smith and Others, 1964, Hurr and Schneider, 1972, Robson, 2000, Lindsay and Others, 1998 and 2005). More recently, the Colorado State University, (CSU, 2013) updated the surface water and groundwater hydrology, while the Colorado Water Conservation Board prepared an extensive McGrane Water Engineering, LLC 1669 Apple Valley Rd. • Lyons, CO 80540 • Phone: (303) 917-1247; email: dennis@mcgranewater.com Bernhardt Pit Groundwater Evaluation May 2023 Page 11 of 31 study on the SPR as part of the South Platte River Decision Support System project (CDM, 2006 and 2013). In 2014, in response to observed evaluated water levels around Gilcrest (4 miles to the east), and LaSalle, the Colorado Geological Survey (CGS) conducted a study (Barkmann and Others, 2014) focusing on groundwater level trends. Barkmann reported using the SPDSS data as the basis for their analysis. The most recent geologic mapping was also prepared by the Colorado Geological Survey (Palkovic and Others, 2018), which we used to better refine the western edge of the alluvial aquifer. Surficial Geology Figure A2 shows the site surficial geology mapped by the CGS (Palkovic and Others, 2018). The alluvium within the model areas consists of alluvial (Qa) sand and gravel (geologic map symbols: Qa, Qal, Qa2, and Qa3 based on their age (recent to older). The western alluvial aquifer boundary is in contact with the Fox -Hills sandstone (geologic symbol Klf) at the western edge of the Bernhardt pit. The floodplain extends approximately four miles east of the proposed pit to near the Town of Gilcrest where it becomes overlain by wind blow dune sand and loess (fine silt and sand) deposits (Qe). Well Depth Figure A2 also shows the reported well depths from 200 wells within the study area. For this map to be meaningful, we assume that the depth of the wells is at the base of the alluvial aquifer (ie. top of bedrock). Assuming this, the alluvium appears to deepen to approximately 60 feet on the eastern side of the model and be >70 feet by the eastern edge of the study area. Water Level Contours We created a water table map (Figure A3) using available data from registered SEO wells (Table Al) and the Bernhardt monitoring wells (Table A2) using the March 31, 2023 measurements. The water table elevations from SEO wells were determined by subtracting the reported depth to water when drilled from well site elevations interpreted from US Geological Survey 10m Digital Elevation Model (DEM) data sets. The white 10 ft elevation contour lines shown on Figure A3 are best drawn approximately 500 feet upgradient from the river elevation based on USGS DEM data which reflects the slight imprecision of the DEM elevations (Haneberg, 2006). Groundwater flows perpendicular to the water level contours. The water table elevation at the west end of the model is at approximately 4630 ft (msl) and the water table gradient falls approximately 25 feet to approximately 4605 ft (msl) on the east end of the model. Most of the water coming into the model area is from the south and southeast. The contours show that the SPR is a gaining stream throughout the reach. Bedrock Elevation Contours Figure A4 shows the elevation contours of the structural top of bedrock digitized from Robson and Others (2000) based on the ground surface topography above the floodplain combined with the elevation of bedrock determined from drilling data. West of the pit, the bedrock rises abruptly to a large hill known locally as the Wildcat Mound (within 4900 ft contour) which extends over 200 feet above the floodplain. Although the Robson contours match very well with the SEO well data, we did need to modify the contours slightly to reflect the Bernhardt monitoring wells (Table McGrane Water Engineering, LLC 1669 Apple Valley Rd. • Lyons, CO 80540 • Phone: (303) 917-1247; email: dennis@mcgranewater.com Bernhardt Pit Groundwater Evaluation May 2023 Page 12 of 31 A2). This effectively widened the alluvium approximately 400 ft (two model cells) further west than Robson. Water Level Fluctuations In 2014, at the request of the State legislature, the Colorado Geologic Survey conducted a study to evaluate observed increases in water levels in the Gilcrest/LaSalle area. The nearest well (SB00406619CBS) that was part of the study is located approximately %2 mile east of the pit, across the SPR river, in Section 19, T4N, R66W (Barkmann and Others, 2014, Fig. E4). The published data only extends from 1966 to 1975 and it shows a seasonal fluctuation of approximately 1 to 2 feet. The purpose of J&T's routine measurements of Bernhardt pit monitoring wells is to evaluate site specific seasonal fluctuations to determine if there will be any future issue. Saturated Aquifer Thickness We calculated the aquifer saturated thickness as the difference between the water table (Figure A3) and the top of bedrock (Figure A4). Figure A5 shows how the saturated aquifer thickens from zero on the west side of the alluvium (at the Pit boundary) to approximately 25 - 30 feet at the SPR. The saturated aquifer thickness increases to over 50 feet in the eastern portion of the study area. Well Yield Well yield is proportional to the aquifer saturated thickness. We plotted reported well yields extracted from the State's well database on Figure A6. Well yields from domestic wells are less than 15 gpm. Agricultural wells are scattered throughout the study area and typically range from 800 (yellow squares) to over 2000 gpm @ink squares). There is one 800 gpm agricultural well located on the south side of the Bernhardt pit (permit 85-RF) that will likely see some effect of pit mounding (See Figure A10). The yield of the well will likely not be effected because of the slight increase in water level. 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 A5). The resulting transmissivity distribution used in the model is consistent with Barkmann (2014, Fig. E9) who used refined aquifer properties from the SPDSS model (CDM, 2006, Fig. 7a). The computed transmissivity ranges from 0 to 150,000 gpd/ft west to east across the pit area (in the S24, T5N R67W), and up to 250,000 gpd/ft in the southeastern corner of the model. Since the transmissivity is equal to the hydraulic conductivity (a measure of permeability) multiplied by the saturated thickness (Figure A5), we used a constant hydraulic conductivity value of 600 ft/day to best duplicate Barkmann's transmissivity distribution (note: 600 ft/day x 33 ft thick x 7.48 gal/fr3 -150,000 gpd/ft' 2). A hydraulic conductivity of 600 ft/day his consistent with other models we constructed for gravel pit impact analyses along the SPR (MWE, 2015, 2019, 2020, and 2022). 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) McGrane Water Engineering, LLC 1669 Apple Valley Rd. • Lyons, CO 80540 • Phone: (303) 917-1247; email: dennis@mcgranewater.com Bernhardt Pit Groundwater Evaluation May 2023 Page 13 of 31 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 Bernhardt pit. The model consists of one layer, 55 rows and 75 columns using 200 foot square model cells. Model Boundary Conditions Bedrock outcropping on the west side of the model is modeled using no -flow model cell boundaries. The bottom bedrock surface was digitized in ESRI GIS software and imported into the model on a 200 ft grid. The south, north and east sides of the model consist of MODFLOW Constant Head (CH) cells that establish a fixed gradient within the stream alluvium. We assigned MODFLOW "River" cell stage elevations using 10m DEM data, and interpolating in between. The southern -most, up -gradient River cell elevation was 4750 ft (msl) and the northern most down gradient elevation was 4705 ft (msl). 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, our model creates more conservative (ie. more) modeled "change." 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, Task 34.3 Streambed Conductance Figure 9) evaluated the streambed permeability at two sites (SC -O7 and SC -08 within 10 upstream and downstream of Bernhardt pit, and came up with Kh values ranging from 137 ft/day to 377 ft/day. We believe these rates are too high because they are too close to our horizontal K (Kh) value (600 ft/day). 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). 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 October 2017, we measured the river widths at the south (140 ft), middle (113 ft) an northwest (195 ft) corners of the model area (average = 149 ft). Representative MODFLOW River cell parameters are shown in the table below. MODFLOW River Cell Parameters *Width (ft) Length (ft) Streambed Conductance Ksb/m (day^ -1) COND (ft^2/day) 150 200 36 1080000 All River cells were assigned a COND value of 1,080,000 ft^2/day. The flow from the river into the aquifer is determined by multiplying COND by the head difference in the river and the underlying model cell. With such a high COND value, water freely flows between the SPR and the aquifer.

Pre -slurry Wall Run The initial run pre -slurry wall run (Bernhardt_SS7) represents the pre -slurry wall conditions. Figure A8 shows the modeled water table contours (blue) compared to "target" contours shown. in Figure A3. Figure A8 also shows the locations of "Constant Head" cells which establish the overall model gradient and the model grid. In this run the Bernhadt pit cells are "on" which allows water to flow through them. The purple "dry" cells are where the modeled water level are below the bottom of the aquifer. This makes sense because there are not wells (yellow dots) within the dry cell area. Observed vs. Modeled Heads We compared the predevelopment observed well water levels and their corresponding modeled cell value in the figure below and the calibration statistics are included in the table to the right.

The best fit line shown above has a slope of 0.9998:1 which is a very close to perfect when considering all the data (no SEO well data was excluded). The Root Mean Squared (RMS) error (6.73 ft) is the square of the difference between the observed and modeled values (aka "residual"). We feel this value is reasonable considering the data used covers a 60 -year period that includes fluctuations caused by well pumping, river fluctuations and agricultural return flows. We did not spend a considerable time trying to obtain a better match heads because the model results (Figure A9) are insensitive to aquifer parameters as discussed below in "Model Sensitivity" section. Residuals McGrane Water Engineering, LLC 1669 Apple Valley Rd. • Lyons, CO 80540 • Phone: (303) 917-1247; email: dennis@mcgranewater.com Bernhardt Pit Groundwater Evaluation May 2023 Page 15 of 31 A residual is the difference between observed and modeled values. The GWV8 program calculated residuals as the difference between modeled and observed values (the modeled value is determined based on the observed point location within the modeled cell). The distribution of residuals are shown on Figure A9. Residuals for the Bernhardt pit monitoring wells range from +0.2 ft to -1.6 ft which is less than the expected seasonal fluctuation. In general, modeled water levels are higher (blue positive values) east of the SPR and less than observed values (red negative values) west of the SPR. We believe this suggests that agricultural pumping east of the SPR may have suppressed measured water levels and the modeled levels better reflect predevelopment conditions. We simply believe that the small range of residuals around the Bernhardt pit supports our belief that the model results are accurate. Mass Balance Table A3 shows the model mass balance results (Run: Bernhardt_SS7) which shows the inflow and outflow components that include alluvial aquifer inflow and outflow and river leakages in and out of the SPR. The total aquifer inflow and outflow balance at 17.98 cfs. The SPR river gains approximately 8.18 cfs (13.56 — 5.38) which is approximately 2.7 cfs per mile. The mass balance error is 0.01% based on the difference between inflows and outflows. This low RMS and low model error support our conclusion that the model has a high level of accuracy. Table A3 also shows the model mass balance result (Run: Bernhardt_SS8) which shows the inflow and outflow components when the pit cells are turned off. The total aquifer inflow and outflow balance is 18.05 cfs. We do not believe the small difference between the total mass balances (.07 cfs) reflects any significant source of model error. Water Level Changes Caused by the Bernhardt Slurry Wall In run <Bernhardt_SS8>, we turned the pit model cells off and used the output heads from the initial run as starting heads. Figure A10 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 south and east sides of the pit (left side of model) reflect mounding. Negative values on the north and east sides of the pit reflect lower water levels in the "shadow" of the pit. The maximum mounding on the upstream side is approximately + 2.5 ft and the maximum shadowing is approximately -2.5 ft on the north side (right side of the figure). Mounding greater than 0.5 feet extends approximately 1,500 feet up -gradient (south), and shadowing less than -0.5 feet can be expected approximately 2000 feet downgradient (north). There are five registered wells located within modeled change between 0.5 and 1.0 ft as summarized in Table 1. Four of the wells are located in the mounding area on the up -gradient side of the pit and one well (13701-F) is located on the downgradient shadow side. Two of the four up -gradient wells belong to the I3ernhardt's which are now owned by the applicant.

However, none of these wells none are located with the modeled mounding area. Conclusions and Recommendations We do not believe the Bernhardt Pit slurry wall will have any adverse effect on the wells identified in Table 1 because the modeled impacts are small and less than the seasonal groundwater change. Therefore, we do not expect any of the well owners within the area of change will notice any impacts. If they do, we recommend that ongoing monitoring occur to quantify those impacts. Model Sensitivity The modeled mound and "shadow" impacts are insensitive to the hydraulic conductivity (K) of the aquifer. A decrease in K causes a proportional increase in model inflows, but also decreases the hydraulic connection with the SPR which offsets less mounding or shadow effects. Therefore, we did not spend excessive time trying to match modeled verses observed heads by changing K values. We did conduct a model run where we dropped the K from 600 ft/day to 300 ft/day which did not significantly change the head residuals. The model results are very sensitive to the presence of the SPR, but there is no realistic chance that the river is going away any time soon. Model results are also insensitive to streambed leakance. Even using a conservatively low Ksb value of 36 ft/day, the SPR is still wide enough and the aquifer is permeable enough to rapidly 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 +/- 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 10) 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 model results are reasonably accurate for the purpose of this study.

Date: Mat 2023 Datum/Projection: NAD83/Colorado State Plane North, feet E.;M9� Wafl Engineering, LLC 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 134 -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 the Great Plains Ruderal Grassland and Shrubland (98%) and disturbed (2%). 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. The South Platte River and adjacent eastern cottonwood floodplain and woodland, provides suitable habitat for wildlife species and MBTA species. The South Platte River and associated vegetative community will not be impacted by the proposed project. Non -raptor birds No non -raptor migratory bird nests were observed within the survey area. However, prior to vegetation removal a nest survey should be completed to ensure that no nests have become established within the survey area and active nests, if any, are not disturbed. Non -eagle Raptors No non -eagle raptor nests were observed and no CPW mapped non -eagle raptor nest protection zones are located within the survey area (CPW 2023a). 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 '/ to % mile of the survey area to ensure compliance with CPW recommendations. Eagles CPW SAM data identifies a bald eagle nest listed as "destroyed" being directly northeast of the survey area. Per CPW monitoring logs, the eagle nest has been inactive from 2019-2021, and destroyed in 2022. A field visit by ERC on January 25, 2023 confirmed the identified nest no longer exists and the nest area is no longer being utilized with no efforts by eagles to rebuild the nest. Therefore, the nest site and the survey area is not subject to any restriction per CPW protective buffer zone recommendations or USFWS Bald Eagle Protection Act. 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 r JUT Consulting, Inc. IHC Scott, Inc. Bernhardt Sand and Gravel Pit DRMS 112 Permit Application 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.

(ERC) has prepared this report at the request of the property representative, J&T Consulting, Inc. The 134 +/- acre property referred to herein as the Bernhardt Site (survey area) is located near Milliken, 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), Colorado Parks and Wildlife (CPW) Colorado Statute Title 33 and Rule 6.4.8 of the Construction Materials Rules of the Colorado Mined Land Reclamation Board Exhibit H Wildlife Information. 2.0 GENERAL SURVEY AREA DESCRIPTION The survey area is located approximately 1 mile south of the intersection of Weld County Road 46 and Weld County Road 25 near Milliken in the Wildcat Mound -South Platte River watershed (HUC 101900030604). More specifically, the survey area is located in Section 24, Township 4 North, Range 67 West, in Weld County. Approximate center point of survey area is latitude 40.300711° north, longitude - 104.834787° west. From the intersection of Weld County Road 46 and Weld County Road 25, south of Milliken, the survey area can be accessed by heading south on Weld County Road 25 for approximately 1.15 miles until reachieg the survey area from the north. The survey area is comprised of ruderal grasslands with fringes of cottonwood trees and American elm trees along the southern border and adjacent cottonwood trees to the east. Refer to Figure 1 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 4,722 feet above mean sea level (AMSL). The vicinity of the survey area is comprised of agricultural land to the north, the South Platte River to the east, ruderal grassland and shrubland the south and to the west. The landscape within the survey area is predominantly characterized as the Great Plains Ruderal Grassland and Shrubland (NatureServe 2023). Great Plains Ruderal Grassland and Shrubland The Great Plains Ruderal Grassland and Shrubland is dominated by exotic, invasive grasses and forbs. These species can become abundant after significant disturbance, often associated with agricultural activities, or a disruption of natural disturbance regimes including long-term, heavy grazing, planting exotic species for livestock forage, plowing land and then abandoning it, and a disruption of the natural fire regime. Vegetation cover varies from low to very high. Abundant species vary greatly depending on the geographic location, seed sources, and nature of land use. Within the survey area, the vegetative community generally comprises approximately 50% ground cover mainly consisting of ruderal species including Russian thistle ISalsola kali) intermixed with cheatgrass (Bromus tectorum), smooth brome (Bromus inermis), kochia (Bassia scoparia), prickly lettuce (Lactuca serriola), field bindweed (Convolvulus arvensis), diffuse knapweed (Centaurea diffuse!) and pepper weed (Lepidium latifolium). Disturbed The Disturbed communityincludes gravel roads, railroads, and barren grounds associated with oil and gas related activities and contains closely cropped vegetation such as well as vegetation growing in urban ERC Bernhardt Site Threatened -Endangered Species and General Wildlife Screening materials, such as pavement, from dry lands to emergent wetlands. Tree canopy varies from 0 to 100% (e.g., open to shaded lawns and gardens) (NatureServe 2023). This community is found along the survey area boundaries and is comprised primarily of two -track roads dominated by Russian thistle and kochia. Eastern Cottonwood Floodplain Woodland Land east and abutting the survey area contains the South Platte River corridor and is comprised Eastern Cottonwood Floodplain Woodland. This vegetative community occurs near rivers and large streams throughout the Great Plains of the U.S. and Canada and extends west into Wyoming and New Mexico. It is dominated by eastern cottonwood (Populus deltoides) throughout its range. The understory composition and structure are variable. A shrub layer may be present, with species such as Salix spp., Symphoricarpos occidentalis, and Prunus virginiana predominating. Sites experience seasonal floods, which, after receding, leave areas available for colonization. Woodland floodplains in the Great Plains, nearly always dominated by Populus deltoides. The understory often has mid- and tallgrass components from the surrounding prairie, though recently scoured sites can be barren or dominated by early successional species. This vegetative community is outside of the survey area and will not be impacted by the proposed project. 2 A ERC Bernhardt Site Threatened -Endangered Species and General Wildlife Screening !►1�Mikt+� Atom I .; a Amy 4 7� • - • Prepared By: � ERC 2820 Wilderness Place, Suite A Boutdet CO 80301 (303) 679.4820 = RC 1: 4 20 -2 301 • • • ,M -.,- • s • CO 40 AD • • • • - • Map Legend Survey Area Boundary * Approximate Location FIGURE 1 LOCATION AND USGS TOPOGRAPHIC MAP BERNHARDT PROPERTY WELD COUNTY, COLORADO frtk et, rr %.er tai I I 3 r ' ,74•AtiOciftrer.P., '61 • r F A ERC Bernhardt Site Threatened -Endangered Species and General Wildlife Screening Refer to Photos 1-8 below for typical characteristics within the survey area.

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 January 25, 2023, 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 s"gnificant natural vegetation communities within a majority the survey area, which limits the overall quality of potential wildlife habitat. As discussed in Section 2.0, two habitat types were observed within the survey area and are characterized as Great Plains Ruderal Grassland and Shrubland, and Disturbed. Both vegetative communities, the Great Plains ruderal grassland and shrubland (98%) and disturbed (2%) are dominated by non-native or weedy species and are 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 vacant, agricultural land 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 dominate 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 general agricultural practices within 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 (Buteo 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 primarily as Great Plains Ruderal Grassland and Shrubland, which is degraded from a wildlife perspective by historic and current land use practices. • The adjacent and abutting Eastern Cottonwood Floodplain and Woodland vegetative community contains stands of mature and dead cottonwood trees that provide relatively high ecological value to 6 A ERC Bernhardt Site Threatened -Endangered Species and General Wildlife Screening wildlife, migratory birds and raptors. These species may use the floodplain as cover, hunting grounds, and potential nesting habitat. Other wildlife may use the South Platte River as a travel corridor and/or for foraging. The Eastern Cottonwood Floodplain and Woodland vegetative community is outside of the survey area and will not be impacted. However, since the Eastern Cottonwood Floodplain and Woodland community does provide the most important habitat near the survey area, it should be protected to ensure that it remains as a natural buffer between the South Platte River and the survey area 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 bids 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. These migratory birds are protected under the MBTA and killing or possession of these birds (or their parts and nests) is prohibited under the MBTA. The following migratory birds were directly observed and likely utilize the survey area primarily for foraging and limited seasonal nesting. Scientific Name Common Name Anas platyhychos Mallard Branta candadensis Canadian goose Circus hudsonius Northern harrier Melospiza melodia Song sparrow Pica hudsonious black -billed magpie N on -Raptor Migratory Birds N on -raptor migratory birds likely utilize the survey area for nesting on a seasonal basis. These birds, their eggs, and active nests are protected under the MBTA and take or possession of these resources is prohibited. For these non -raptor migratory birds, only the active nest is protected and no buffers or restricted surrounding areas are required. Once the nest becomes inactive, disturbances can occur to the nest and no further agency authorization or coordination is required. Generally, the active nesting season for most non -raptor migratory birds in this region of Colorado occurs between April 1 and August 31. • No non -raptor nests were observed within the survey area. However, seasonal MBTA non -raptor bird nesting activity status can vary seasonally and from year to year. Prior to vegetation removal, a nest survey should be conducted no more than 7-10 days prior any future land use changes to ensure that active nests are not disturbed during the nesting season. Non -eagle Raptors Non -eagle raptor nest sites are regulated by the USFWS under the MBTA with local review from the CPW. The CPW has established recommended protective buffer zones and seasonal activity restrictions for a variety of Colorado raptors (CPW 2020). The CPW species -recommended buffer zones are such that if implemented, should assure that the majority of the individual species will continue to occupy the area. CPW considers a nest to be active when it is frequented or occupied by a raptor during the breeding 7 � ERC Bernhardt Site Threatened -Endangered Species and General Wildlife Screening season, or which has been occupied in any of the five previous breeding seasons. Many raptors use alternate nests in various years. Thus, a nest site may be active even if a particular nest is not occupied in a given year. The CPW also maintains Species Activity Mapping (CPW SAM) data which is an online database that lists the known occurrences, status and recorded nest sites of select raptors and other species within the state of Colorado. • No non -eagle raptor nests were observed and no CPW mapped non -eagle raptor nest protection buffer zones are ocated within the survey area (CPW 2023a). 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 Y2 to 1/4 mile of the survey area to ensure compliance with CPW recommendations. Eagles A bald eagle nest site is identified by CPW SAM data and lists the nest site as "destroyed". Personal email communication with CPW GIS Database Specialist, Robert Sacco stated that the nest was documented as destroyed in February 2022 with no known cause. A field visit was conducted on January 25, 2023 and January 31, 2023 to document the presence and/or absence of the nest and/or any nest remnants. During the field visit, the last known location of the nest site was traversed, and ERC observed a large broken branch and possible remnants of the previously documented nest site. No other nests were observed within the area and no eagles were observed. The second field visit on January 31, 2023 was conducted to determine nest area activity and to determine if any eagles were attempting to rebuild the nest. A two-hour field investigation was completed on the morning of January 31 and began approximately a 1/2 hour before sunrise and continued for 1 %2 hours after sunrise. The field observation was performed through direct visual observations (aided by binocular) while stationed at an appropriate vantage point within the survey area. During the observation, no eagles were observed within the nest area and no eagles were observed attempting to rebuild the nest. Refer to Photos 9-12 below for documentation of the potential eagle nest remnants. Photo 9.

No bald The nest has been documented as unoccupied in 2019, 2020, and 2021. Per the CPW monitoring data, the nest was documented ' gone/destroyed" on February 6, 2022. ERC observation in January 2023 also confirmed the nest has been destroyed and the nest area remains unoccupied. A second nest is depicted 0.68 -mile northeast of the destroyed nest (Figure 3). This second nest is outside the survey area boundary and both the %-mile and %2 -mile protective buffer zones do not encroach upon the survey area and will not be impacted due to the proposed project. The CPW recommended guidelines (CPW 2020) only consider a nest active when it is "frequented or occupied by a raptor during the breeding season, or which has been occupied in any of the five previous breeding seasons." Information regarding destroyed nests is not available within the CPW recommended guidelines. The nest site adjacent to the survey area is considered destroyed and inactive as there has been no nesting activity for 5 consecutive breeding seasons (2019, 2020, 2021, 2022, 2023). Therefore the nest site and survey area is not subject to CPW recommended protective buffer zones. Figure 3 below depicts CPW-provided nest location and status as of February 6, 2022. 9 ERC Bernhardt Site Threatened -Endangered Species and General Wildlife Screening • sty►• mast •atsta•v•a:w The USFWS ultimately has the regulatory authority of bald eagles and has established the National Bald Eagle Guidelines (USFWS 2007). The guidelines state that a bald eagle nest site is also considered not active if not used or occupied during the 5 previous breeding seasons. In addition, the guidelines state where "nests are blown from trees or are otherwise destroyed by the elements, a nest site should be continually protected in the absence of a nest for up to 3 complete breeding seasons to ensure that eagles do not rebuild and reoccupy a nest site". Taking into consideration that the nest site has not been active for the past 5 breeding seasons and has recently been destroyed, these additional monitoring years do not apply. Therefore, the nest site and the survey area are not subject to USFWS restrictions for activities within the survey area. 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 10 Bernhardt Site Threatened -Endangered Species and General Wildlife Screening project (USFWS 2023 ) (Project Code: 2023-0036832). The species list for the survey area has identified potential for a total of 9 threatened or endangered species within the survey area. Species Not Present The following federal y 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 f abitat 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 Eastern black rail Laterallus jamaicensis FT NO TAKE * Status key: FT— Federally listed as threatened • The survey area does not contain the specific habitat characteristics necessary to support the 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 A 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 associated with a proposed gravel pit mine and a proposed water supply is not known at this time 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 US=WS. The consultation is a mandate for water depletion projects that may affect threatened and endangered species that rely on the South Platte River. • 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 lard use changes would not be considered a new water depletion. Therefore, the project would result i-i No Take to these species. • Depletions to the South Platte River may adversely affect the species listed above. Depletions to the South Platte River include pumping for municipal, industrial, or commercial purposes. As such, consultation with USFWS under Section 7 of the ESA would be required if the project contains a federal nexus; such as federal funding or a federal permit. The project is assumed to be an industrial development suppliec by an existing municipal water supply and therefore, would have no effect on these listed species, their habitats, or proposed or designated critical habitat. 11 A ERC Bernhardt Site Threatened -Endangered Species and General Wildlife Screening Species Potentially within Range The following federally listed threatened and endangered species are identified to occur or historically occur within Weld Cointy (USFWS 2023). 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 Preble's meadow jumping mouse Zapus hudsonius preblei FT NO TAKE Ute Ladies' -tresses orchid Spiranthes diluvialis FT NO TAKE Monarch Butterfly Danaus plexippus C NO TAKE * Status key: FT - Federally listed as threatened C— Candidate listed species 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. In Colorado, PMJM populations are generally restricted to locations along the Front Range foothills and adjacent riparian areas. Schorr and Mihlbachler (2018) describe typical PMJM habitat being restricted to dense shrub cover and dense herbaceous vegetation along wetland and riverine systems. Armstrong et al. (1997) characterize PMJM habitat as `well -developed plains riparian vegetation with relatively undisturbed grassland and a water source in close proximity: Also noted in Armstrong et al. (1997) was a preference for "dense herbaceous vegetation consisting of a variety of grasses, forbs and thick shrubs" . 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. Areas that are highly disturbed or modified (including landscaped lots and paved areas) or wetland areas dominated by cattails are excluded from this recommendation. • Two trap sites are recorded in the vicinity of the survey area along the South Platte River. The nearest trap site is located 0.9 mile southwest, and the furthest is 3.14 miles northeast of the survey area. No PMJM individuals were present during either of the surveys (USFWS 2018). No critical habitat occurs within the survey area (USFWS 2023). The nearest critical habitat, Critical Habitat Unit 3- Buckhorn Creek, is located approximately 25 miles to the northwest. The USFWS Block Clearance Map for the Denver Metro Area (ERO 2010) which identifies areas exempt from further review for PMJM habitat, shows the survey area occurring outside of the Block Clearance Zone. • Vegetation communities within the survey area are not typical habitat for the PMJM. The Great Plains Ruderal Grasslanc and Shrubland along the agricultural field fringes are not conducive to PMJM and the surface water from the South Platte River is defined by steep and well defined banks. The agricultural field which makes up the majority of the survey area contains primarily of upland herbaceous cover that is repeatedly disturbed due to agricultural practices 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. 12 ERC Bernhardt Site Threatened -Endangered Species and General Wildlife Screening 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 Wildcat Mound -South Platte 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 is 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. MONARCH BUTTERFLY (DANAUS PLEXIPPUS) The monarch butterfly is listed as candidate species under the ESA. Adult monarch butterflies are large and conspicuous, with bright orange wings surrounded by a black border and covered with black veins. The black border has a double row of white spots, present on the upper side of the wings. Adult monarchs are sexually dimorphic, with males having narrower wing venation and scent patches. The bright coloring of a monarch serves as a warning to predators that eating them can be toxic. Asa candidate species, the monarch butterfly has no statutory protection under the ESA, however the USFWS encourages cooperative conservation efforts because they are species that may warrant future protection under the ESA (USFWS 2017). No monarch butterflies or milkweed species were observed within or surrounding the survey area. The survey area historically has been highly modified with agricultural practices. However, future land use changes should consider and describe any planned conservation measures for the monarch butterfly. Conservation measures can include habitat management such as the inclusion of native milkweed plant species in restoration efforts, reducing herbicide and pesticide use within the survey area, and/or creating a conservation easement for habitat protection. Such best management practices will aid in maintaining and/or enhancing the future survival of the monarch butterfly survival. However, these are not regulatory requirements. 13 � ERC Bernhardt 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 uncer 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 2023b). 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 2023b). 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 2023b and USFWS 2023).

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.

Common Name Scientific Name Status* Black -footed ferret Mustela nigripes SE Burrowing owl Athene cunicularia ST `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. gunnisovii), 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 2039). Any future land use changes within the survey area should have no effect on the continued existence or potential habitat of this species. BLACK -FOOTED FERRET (MUSTELA NIGRIPES) The burrowing owl (Owl) is listed as a state threatened species in Colorado. The Owl is small (length of 24 centimeters), long-legged, boldly spotted, and barred with brown and white. The Owl is a breeding species across the plains of eastern Colorado however rarely winters in the state. Nesting habitat is in burrows, especially in both active and inactive prairie dog colonies, located in grasslands, mountain parks, well - drained steppes, deserts, prairies and agricultural lands from late March through October. The Owl can usually be observed on low perches such as fence posts, dirt mounds or the ground. Clutch size of this Owl averages six to seven and incubation lasts up to 30 days. The owlets usually run and forage at 4 weeks 15 ERC Bernhardt Site Threatened -Endangered Species and General Wildlife Screening and fly at 6 weeks. Primary threats to existence of this species are habitat loss due to intensive agriculture, habitat degradation and fragmentation due to control of burrowing mammals and predation by cats and dogs. No Owl 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 black -tailed prairie dog colonies are located within the survey area. Much of the land within the survey area is regularly grazed which further limits the potential use of the survey area by 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 134 -acre survey area. The following provides 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 the Great Plains Ruderal Grassland and Shrubland (98%) and disturbed (2%). 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. The South Platte River and adjacent eastern cottonwood floodplain and woodland, provides suitable habitat for wildlife species and MBTA species. The South Platte River and associated vegetative community will not be impacted by the proposed project. 3. Non -raptor birds No non -raptor migratory bird nests were observed within the survey area. However prior to vegetation removal a nest survey should be completed to ensure that no nests have become established within the survey area and active nests, if any, are not disturbed. Non -eagle Raptors No non -eagle raptor nests were observed and no CPW mapped non -eagle raptor nest protection zones are located within the survey area (CPW 2023a). 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 to 'A mile of the survey area to ensure compliance with CPW recommendations. Eagles CPW SAM data identifies a bald eagle nest listed as "destroyed" being directly northeast of the survey area. Per CPW monitoring logs, the eagle nest has been inactive from 2019-2021, and destroyed in 2022. A field visit by ERC on January 25, 2023 confirmed the identified nest no longer exists and the nest area is no longer being utilized with no efforts by eagles to rebuild the nest. Therefore, the nest site and the survey area is not subject to any restriction per CPW protective buffer zone recommendations or USFWS Bald Eagle Protection Act. 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 16 ERC Bernhardt Site Threatened -Endangered Species and General Wildlife Screening 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.

(ERC) provides the following Technical Memorandum which summarizes the findings of a bald eagle (Haliaeetus leucocephalus) nest site (nest site) evaluation and the interpreted applicable regulations, enforcements and potential restrictions that may be subject to the proposed Bernhardt Property (project site) due to the nest site. The project area is under consideration for future land use changes, however the nest site which is located outside and adjacent to the project area may impose restrictions within the project area due to its close proximity. 2.0 Location The nest site is located near Milliken, Weld County, Colorado. More specifically, the nest site is located in Section 19, Township 4N, Range 66 West, (latitude 40.302937° N, -104.828829° W). The immediate land use within the nest site area is a cottonwood floodplain adjacent to the South Platte River. Land use in the vicinity of the nest site has historically been subject to agricultural use and past oil and gas operations. A site vicinity map depicting the nest location is provided in Figure 1. The project area, southwest of the nest site, is —134 acres and was used historically as agricultural land. The project area is now vacant and consists of ruderal grassland. 2.0 Background The nest site is been identified by the Colorado Division of Parks and Wildlife (CPW) as a documented bald eagle nest site (CPW 2022). Bald eagles and their nests are federally protected by the USFWS under the Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (Eagle Act) with additional protections from the CPW. Both USFWS laws prohibit "take" and possession of eagles, their parts, nests, and eggs. Under the Eagle Act, "take" includes to pursue, shoot, shoot at, poison, wound, kill, capture, trap, collect, molest or disturb (50 CFR 22.6). Locally, the USFWS relies on the CPW for determination of a "take", especially in more indirect situations that only result in land disturbance within the recommended protective buffer zone and not direct physical impact to the birds, nests or nest trees. CPW maintains a leadership role with respect to raptor management in Colorado; however, it is important to keep in mind that the primary authority for the regulation of "take" and the ultimate jurisdiction for bald eagles rests with the USFWS under the Migratory Bird Treaty Act (16 U.S.C. 703-712) and the Bald and Golden Eagle Protection Act (16 U.S.C. 668-668e). The CPW has developed the 2020 Guidance: "Recommended Buffer Zones and Seasonal Restrictions for Colorado Raptors" which provides recommended tolerance limits or protective buffer zones for various species of raptors in addition to seasonal restrictions in response to human activity. The CPW guidelines recommend a No Surface Occupancy (NSO) within 'A -mile (1,320 -feet) of an active bald eagle nest and "no permitted, authorized, or human encroachment activities within A -mile (2,640 -feet) of an active bald eagle nest from December 1 through July 31". Note, the CPW recommended buffer is more extensive than ERC Bald Eagle Nest Evaluation — Bernhardt Property Project the USFWS 2007 Bald Eagle Guidelines which recommend a buffer of only 660 feet. In Colorado, eagle nesting typically occurs November 15 to February 15 with egg laying beginning in February (Kingery 1998). Hatching of young occurs on different days with eaglets making their first flights about 10 to 12 weeks after hatching and fledge (leave their nests). The time between egg -laying and fledging is approximately four months (USFWS 2007a). Colorado eagles frequently fledge two and sometimes three young (Kingery 1998). 3.0 Nest Evaluation As part of the eagle lest evaluation, ERC reviewed publicly available information including the CPW Species Activity Mapp ng (SAM) Data. The CPW SAM Data, which is available in Geographic Information Source (GIS) format from the CPW website, shows protective buffer zones for raptors and other wildlife distribution data for wildlife species within the State of Colorado. The specific nest site in question is documented as Nest 02495B which can be seen in Figure 2 below. Figure 2 is a screen shot of the CPW SAM data. A second nest can be seen on Figure 2 and is noted as Nest 02495A. Nest 02495A is located to the northeast and is listed as active. Nest 02495A is well outside of the project area boundary and both the %-mile and %-mile protective buffer zones do not encroach upon the project area and Nest 02495A will not be impacted as part of the project. Nest 02495B is the nest site being evaluated as part of this Technical Memorandum and is located approximately 300 -feet outside and northeast of the project area boundary per the CPW data In further review of the CPW SAM data, and in communication with CPW, the eagle nest site has been documented as "destroyed" on February 6, 2022. CPW also provided monitoring data (included in Appendix A). According to the CPW-provided monitoring data, the nest has been monitored since April 5, 2019 and includes eight monitoring event entries. The table below summarizes the CPW monitoring data and states whether the iest was occupied or not.

During the field visit, the last known location of the nest site was traversed, and ERC observed a large broken branch and possible remnants of the previously documented nest site. No other nests were observed within the area and no eagles were observed. The second field visit on January 31, 2023 was conducted to determine nest area activity and to determine if any eagles were attempting to rebuild the nest. A two-hour field investigation was completed on the morning of January 31 and began approximately a Y2 hour before sunrise and continued for 1 1/2 hours after sunrise. The field observation was performed through direct visual observations (aided by binocular) while stationed at an appropriate vantage point within the project area. During the observation, no eagles were observed within the nest area and no eagles were observed attempting to rebuild the nest. 4 � ERC Bald Eagle Nest Evaluation — Bernhardt Property Project Refer to photos 1-4 below for documentation of the potential eagle nest remnants.

View east of the Eastern Cottonwood Floodplain and Woodland which is adjacent to the nest area. The nest has been documented as unoccupied in 2019, 2020 and 2021. Per the CPW monitoring data, the nest was documented "gone/destroyed" on February 6, 2022. ERC observation in January 2023 also confirmed the nest has been destroyed and the nest area remains unoccupied. 4.0 Conclusion The CPW recommenced guidelines (CPW 2020) only consider a nest active when it is "frequented or occupied by a raptor during the breeding season, or which has been occupied in any of the five previous breeding seasons." Information regarding destroyed nests is not available within the CPW recommended guidelines. The nest s to adjacent to the project area is considered destroyed and inactive as there has been no nesting activity for 5 consecutive breeding seasons (2019, 2020, 2021, 2022, 2023). Therefore, the nest site nor the project area is subject to CPW recommended protective buffer zones. In review of the USFVJS 2007 Bald Eagle Guidelines, guidelines state that a bald eagle nest site is also considered not active if not used or occupied during the 5 previous breeding seasons. In addition, the guidelines state where "nests are blown from trees or are otherwise destroyed by the elements, a nest site should be continually protected in the absence of a nest for up to 3 complete breeding seasons to ensure that eagles do not rebuild and reoccupy a nest site". Taking into consideration that the nest site has not been active for the past 5 breeding seasons and has recently been destroyed, these additional monitoring years do not apply. Therefore, the nest site and the project area are not subject to USFWS restrictions for activities within the project area. 5 ERC Bald Eagle Nest Evaluation — Bernhardt Property Project In conclusion, based on this evaluation the nest site (02495B) is considered inactive and destroyed and therefore, the project area is not subject to any bald eagle related restrictions from the USFWS or the CPW.

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. usDA Natural Resources Web Soil Survey Conservation Service National Cooperative Soil Survey 5/15/2023 Page 1 of 5 Map Unit Description --Weld County, Colorado, Southern Part 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.

During the field inspection, dominant vegetation was recorded, representative hydrologic indicators were noted, and soil samples were examined for hydric indicators. 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). These definitions are the basis of this delineation method. 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 (0HWM) were classified as a non - wetland (upland) and mapped as such. Any area determined to be potential waters of the U.S. was delineated in the field with pink flagging identified with 'WETLAND BOUNDARY' printed on it and sequentially labeled alpha -numerically (i.e., Al, A2...). 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. All aquatic resources delineated within the survey area are depicted on the Aquatic Resource Delineation Map (Appendix A). Wetland Determination data sheets are provided in Appendix B.

Wetland Determination data sheets are provided in Appendix B. Refer to Table 3 for a list of plant species identified within the survey area (Lichvar et al. 2016). AQUATIC RESOURCE A ;0.005 ACRES) Aquatic Resources A is a topographical depression within the southwestern corner of the survey area. The depression contains a FEM1A wetland habitat. Hydrology within the topographical depression appears to be supported by surface water run-off as well as irrigation run-off from the agricultural field during the growing season. A direct surface water connection to other Waters of the U.S. was not observed. The topographical depression was delineated based on the presence of hydrophytic vegetation, hydric soils and hydrology. 4 Habitat Type based on Cow9rdin et al. 1979. A ERC Bernhardt Pit Project Site Aquatic Resource Delineation Report February 17, 2023 The vegetation within the topographical depression contains narrow leaf willow, broad leaf cattail and smooth brome.

Overview facing east of Aquatic Resource B, a topographical depression within the southwest corner of the survey area. Broad leaf cattail present with a ruderal upland herbaceous understory. Aquatic Resources C is a topographical depression within a ditch along the southern boundary of the survey area. The depression contains a PEM1A wetland habitat. The topographical depression is situated in a ditch which is located between the survey area agricultural field, and a separate agricultural field to the south. Both agricultural fields bound Aquatic Resource C to the north and south. The topographical depression appears to be the lowest spot contained within the ditch and appears hydrology is primarily supported by surface water run-off as well as irrigation run-off from both surrounding agricultural fields. A direct surface water connection to other Waters of the U.S. was not observed. The topographical depression was delineated based on the presence of hydrophytic vegetation, hydric soils and hydrology. The vegetation within the topographical depression contains primarily broad leaf cattail and cheatgrass. The dominate species within the topographical depression consist of hydrophytic species (FAC-FACW).

Overview facing east of Aquatic Resource C, a topographical depression within a ditch in the southern portion of the survey area. Broad leaf cattail dominates with a ruderal upland herbaceous understory. Aquatic Resources D is a topographical depression in the southeast corner of the survey area. The topographical depression contains a palustrine emergent nonpersistent seasonally flooded (PEM1A) wetland habitat. The topographical depression is surrounded by higher elevation upland habitat and bound to the north, east, south and west. It appears hydrology within the topographical depression is primarily supported by surface water run-off as well as irrigation run-off from the agricultural field within the survey area. A direct surface water connection to other Waters of the U.S. was not observed. The topographical depression was delineated based on the presence of hydrophytic vegetation, hydric soils, and indicators of iydrology. The vegetation within the topographical depression contains broad leaf cattail (Typha latifolia), reed canary grass (Phalaris arundinacea) and smooth brome. The dominate species within the topographical depression consist of hydrophytic species (FAC-FACW). Soils within the topographical depression are generally sandy loam in texture, meeting the criteria for hydric soil indicator F8 (Redox Depressions).

AQUATIC RESOURCE E (SOUTH PLATTE RIVER) OUTSIDE OF THE SURVEY AREA Aquatic Resources E (South Platte River), a known TNW, consists of riverine lower perennial stream bed (R2SB). The South Platte River is situated immediately adjacent and outside of the survey area to the east. The South Platte River flows south to north. The South Platte River was delineated based the ordinary high water mark (OHWM) and consisted of a well-defined bed and bank with flowing water. The riverbanks are steep and incised with various rip -rap (cement blocks, vehicle parts, boulders). Within the channel, vegetation has been stripped due to river flows. Above the channel, adjacent to the survey area, vegetation consists of eastern cottonwood (Populus deltoides) overstory tees with narrowleaf willow (Salix exigua) shrubs scattered throughout. The herbaceous understory is primarily ruderal grassland with smooth brome (Bromus inermis), woods rose (Rosa woodsii), common wild oat (Avena fatua), cheatgrass (bromus tectorum), perennial pepperweed (Lepidium latifolium), and field pennycress (Thlaspi arvense). The dominate species within the floodplain consists of upland plant species (FAC-UPL). The channel containing the South Platte River contains a sandy gravel substrate with primary hydrology indicators of Al (Surface Water) and A3 (Saturation). Secondary indicators include B8 (Sparsely Vegetated Concave Surface), B10 (Drainage Pattern), C9 (Saturation Visible on Aerial Imagery) and D2 (Geomorphic Position). The South Platte River meets the criteria for a wetland based on the presence of an OHWM. Refer to Photos 15-20 below for characteristics within Aquatic Resource E.

Overview south of the South Platte River and the associated OHWM. The survey area cannot be seen from this photo, however the survey area would be located in the background; if it was visible. Photo 20. Overview east of the of the floodplain adjacent to the South Platte River. Some areas exhibit a midstory with narrowleaf willow, however these areas contain an upland herbaceous understory which lack both hydric soils and hydrology. The wetland delineation identified approximately 133.97 acres of upland habitat within the survey area consisting predominantly of ruderal grassland and shrubland with fringes of ruderal grasses, forbs and bare ground. Topography across the survey area is generally flat with a topographic high point of 4,735 feet at the northwestern extent of the survey area. The vegetation community characterized within the survey area has been disturbed by historic and current land use practices associated with agriculture. ERC Bernhardt Pit Project Site Aquatic Resource Delineation Report February 17, 2023 Therefore, existing upland vegetation within the survey area represents somewhat degraded forms of these natural vegetation associations. The upland habitats ac-oss the survey area are dominated by FACU- UPL species with dry and light-colored soils throughout. Hydric soils, a dominance of hydrophytic vegetation, and/or wetland hydrology were not present in the upland habitats within the survey area.

IHG Scott, Inc. Bernhardt Sand and Gravel Pit DRMS 112 Permit Application EXHIBIT L Reclamation Cost A phased and cumulative bonding approach is proposed for the Bernhardt Sand and Gravel Pit mining site operation. The financial warranty required for each phase is the warranty required to completely reclaim that phase. 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.

INC Scott, Inc. — Bemhardt Sand and Gravel Pit Slope Stability Analysis Page ii INTRODUCTION IHC Scott Inc., proposes to mine the property located in the northeast 1/4 of Section 24, Township 4 North, Range 67 West of the 6th Principal Meridian, in Weld County, Colorado. The property is bounded by the private property on all sides, with the South Platte River being adjacent to the southeast boundary of the property. 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 a single pit, and reclaimed as a water storage reservoir. The mining will occur at 2H:1 V slopes. The reservoir will be reclaimed by backfilling the mining slopes with overburden/clay soils at 4.5H:1 V slopes, and will cover an estimated 93 surface acres when full. The actual surface area 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 Cesare Inc./CMT Technical Services. Logs of the borings and monitoring wells 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. J&T Consulting, Inc.

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, five 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 x0.10=0.07. All mining side slopes will be 2H:1 V, and all reclaimed slopes will be 4.5H:1 V. The locations of the cases are shown on the case location map included in Appendix A. Case SS -1 — Gas Line West of Pit. The mining operation is adjacent to a gas line on the west side of the pit. The proposed setback for mining is 53 feet from the gas line. The mining depth was assumed to be 38 feet in this area based on bore log information. Case SS -2 — Gas Line North of Pit. The mining operation is adjacent to a gas line on the north side of the pit. The proposed setback for mining is 91 feet from the power poles/lines. The mining depth was assumed to be 34 feet in this area based on bore log information. J&T Consulting, Inc. IHC Scott, Inc. — Bemhardt Sand and Gravel Pit Slope Stability Analysis Page 2 Case SS -3 — Gas Line Northeast of Pit. The mining operation is adjacent to a gas line on the northeast side of the pit. The proposed setback for mining is 61 feet from the gas line. The mining depth was assumed to be 34 feet in this area based on bore log information. Case SS -4 — Gas Line East of Pit. The mining operation is adjacent to a gas line on the east side of the pit. The proposed setback for mining is 46 feet from the gas line. The mining depth was assumed to be 35 feet in this area based on bore log information. Case SS -5 — Gas Line South of Pit The mining operation is adjacent to a gas line on the south side of the pit. The proposed setback for mining is 45 feet from the irrigation ditch bank. The mining depth was assumed to be 36 feet in this area based on bore log information. The cross -sections located in Appendix B show the estimated phreatic surface associated with each case, the geometry used in the mining/reclamation, 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. All cases were analyzed using mining condition geometry to determine the factor of safety for each case with the steeper mining slopes. Case SS -5, which is the location that is closest to a critical structure (45 feet from the gas line), was analyzed to determine the minimum factor of safety for all reclaimed slopes. J&T Consulting, Inc. INC Scott, Inc. — Bemhardt Sand and Gravel Pit Slope Stability Analysis Page 3 SLOPE STABILITY RESULTS When estimated soil strength parameters are used, 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 results of the static condition and pseudo -static condition slope stability analyses are shown in Tables 2, 3, & 4 below.

INC Scott, Inc. — Bernhardt Sand and Gravel 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.

C. York J -T Consulting, Inc. 305 Denver Avenue, Suite D Fort Lupton, Colorado 80621 From: Mindy Burkitt, SWCA Cultural Resources Specialist Melanie Medeiros, M.A., RPA, SWCA Cultural Resources Principal Investigator Date: March 29, 2023 Re: Cultural Resource Support for the IHC Scott Proposed Bernhardt Gravel Mining Pit in Weld County, Colorado / SWCA Project No. 78991 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 Bernhardt Gravel Mining Pit project (project). The project consists of the new construction of a gravel mining pit on an approximately 132 -acre lot (Parcel No. 105924000023, hereafter referred to as the project area), southeast of Milliken, Colorado, on agricultural land owned by IHC Scott (IHC) (Figures 1 and 2). Development of the proposed gravel mining pit will be subject to permitting through 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 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 2 miles southeast of Milliken, Weld County, Colorado, in the northeast quadrant of Section 24 of Township (T) 4 North (N), Range 67 West (W), as depicted on the 1970 U.S. Geological Survey (USGS) Milliken, Colorado, 7.5 -minute quadrangle (see Figures 1 and 2). The majority of the parcel is a roughly circular, tilled and fallow agricultural field on the T3 terrace of the South Platte River (Figure 3). An earthen levee system surrounds the eastern, southern, and half of the western edges of the agricultural field and a prominent, dissected, northeast -trending terrace or ridge system is northwest of the project area. Additional fallow agricultural fields and reclaimed well pads are north of the project area. The southwest corner of the project area is characterized by a graded lot that is currently being used to store a variety of modern industrial and farming materials; this area, particularly the southwest corner of the project area, is heavily disturbed and has clearly been impacted by modern mechanical excavations and tree removal. Numerous pipelines cross through and border the project area. Vegetation is entirely invasive and noxious weeds, allowing for between 0 and 90 percent bare ground visibility, averaging 70 percent.

Project area, showing the shovel tests excavated to examine deposition. 3 Cultural Resource Support for the IHC Scott Proposed Bernhardt Gravel Mining Pit in Weld County, Colorado One of highest terraces in the Platte River system is termed T3 by geomorphologists because it is the third terrace above the modern level of the river. This terrace is known as the Kersey Terrace on the south side of the river and as the Pleasant Valley Terrace on the north side. This terrace is notable for the high level of glacial gravels mixed with the alluvial sediments deposited during the Pleistocene Pinedale Monarch Glaciation, about 12,000 years before present (McFaul et al. 1994). According to Holliday (1987) and McFaul et al. (1994), among others, the surface of the T3 is characterized by gravel ridges and channels, a result of braided channels of the South Platte River as it deposited glacial outwash materials. Much of this landscape has been flattened by historic agricultural activities. Soils in the project area are predominantly (99 percent) Aquolls and Aquents, gravelly substratum. This map unit is common on swales, floodplains, and streams; consists of loam overlying gravelly sand; and is poorly drained, deep, and derived from recent alluvium (NRCS 2019). Figure 3. Overview of the project area taken from the northwest corner with gallery forest around the South Platte River in the background; view to the southeast. METHODS In February 2023 and prior to fieldwork, SWCA requested a file search and literature review of the project area through the Colorado Office of Archaeology and Historic Preservation to identify records for all previously conducted cultural resource surveys and all previously identified cultural resources within the project area and the Public Land Survey System (PLSS) sections bordering the project area. In addition, SWCA conducted background research that included examination of historical topographic maps, aerial imagery, and geological and soils data for the project area to identify land use patterns and natural features that may signify areas with the potential for archaeological/cultural resources. Following completion of this background research, on March 6 and 7, 2023, SWCA archaeologists Mindy Burkitt and Nick Simpson completed a reconnaissance survey of the project area to identify cultural resources and potential impacts the project may have on those resources. SWCA also excavated three shovel tests to evaluate the subsurface depositional setting and assess the project area for the potential to contain buried cultural material. 4 Cultural Resource Support for the IHC Scott Proposed Bernhardt Gravel Mining Pit in Weld County, Colorado RESULTS File Search and Literature Review Results of the file search and literature review indicate that five cultural resource inventories have been previously conducted in the PLSS sections within 1 mile of the project area. No previous inventories intersect the project area; however, one inventory (WL.E.R10) borders the project area on its north side. Two of these inventories were conducted for pipeline projects; one was conducted for a transportation project; and two were conducted for projects of miscellaneous type (Table 1). Table 1.

The precontact resources consist of a mammoth kill site, two open camps with burials, six open camps, and one isolated find (IF). The Dent Site (5WL269), the mammoth kill site, is officially eligible for the National Register of Historic Places (NRHP) and, like the project area, is located on the T3 of the South Platte River; the Dent Site is approximately 0.25 mile north of the current project area. Of the remaining nine precontact resources, one is officially not eligible, one officially needs data before an NRHP evaluation can be made, one is recommended eligible, and six are recommended not eligible for the NRHP. The 15 historic resources consist of seven railroad -related sites, including one segment each of the Denver, Laramie & Northwestern Railroad and the Union Pacific Railroad —Dent Branch, three sidings, one station, and one unnamed railroad segment; one segment each of Union Ditch and Western Mutual Ditch; one segment of State Highway 60; one bridge; one fort; one school; one trash scatter; and two IFs. One of these resources, the Fort St. Vrain Monument — Fort St. Vrain Site — Fort Lookout (5WL814) is listed on the State Register of Historic Places. The Union Pacific Railroad —Dent Branch is officially eligible for the NRHP. Union Ditch, Western Mutual Ditch, and State Highway 60 are recommended eligible for the NRHP in their entirety, but the segments within the file search area are non -supporting of each resource's overall eligibility. The Fort St. Vrain Siding of the Denver, Laramie & Northern Railroad and Great Western Railroad is recommended to need more data before an eligibility assessment can be made, and no information regarding NRHP eligibility is provided for one resource, the Big Bend School. The remaining historic -age resources are recommended or officially not eligible for the NRHP. 5 Cultural Resource Support for the IHC Scott Proposed Bernhardt Gravel Mining Pit in Weld County, Colorado The single multicomponent resource consists of precontact petroglyph panels and historic graffiti and is officially eligible for the NRHP. None of these previously recorded resources are located in the project area, although 5WL2906, a precontact IF, is located immediately north of the project area. This IF, which is documented as a quartz ground stone fragment, may be related to newly recorded IF 5WL9626 (see Reconnaissance Survey section, below), as the resources are located very close to one another. Of note, the Kersey Terrace has also yielded several of the earliest sites in Weld County, including the Frazier Site (Agate Basin) (5WL268), the Klein site (Clovis) (5WL1368), the Jurgens Site (Cody complex) (5WL53), and the Powars site (Folsom) (5 WL 1369), all of which are within 0.75 mile of the proposed project area.

Sources reviewed include the General Land Office (GLO) plats through the Bureau of Land Management (BLM) website (BLM 2023), USGS quadrangles using the National Geologic Map Database (USGS 2023), and historic aerial imagery available through the Nationwide Environmental Title Research website (NETROnline 2023). Table 3. Historic Maps Reviewed Map Name Map Type/Preparer Date T4N, R67W GLO/Original survey plat 1863 Greeley, Colorado USGS 1:125,000 -scale quadrangle 1902 Milliken, Colorado USGS 1:24,000 -scale quadrangle 1950 Miliken, Colorado USGS 1:24,000 -scale quadrangle 1951 No historic features are present in Section 24 of the 1863 survey plat for T4N, R67W; however, the course of the South Platte River is different, flowing east across the entirety of the section. The 1902 USGS Greeley, Colorado, 1:125,000 -scale quadrangle shows a two -track road west of the project area, traversing the higher elevation terrace system. The 1950 USGS Milliken, Colorado, 1:24,000 -scale quadrangle shows increased settlement in the broader area, including the town of Dent; however, the project area is still undeveloped. The Union Pacific Railroad traverses northeast -southwest through Section 24, west of the project area. The road depicted in the 1902 quadrangle is absent from this map. While there are historic quadrangles from 1954, 1957, 1958, 1961, 1964, and 1965, they are all 1:250,000 -scale quadrangles and lack the detail needed to assess land use and development in and around the project area. Historic imagery available on NETROnline (2023) shows two fence lines along the southern and western extents of the project area in 1948 and 1949, but no further historic features. The marbled nature of the sediment also suggests that this area was highly prone to flooding. By 1956, a small portion of the project area is being tilled and is surrounded by two -track roads; the surrounding area still appears to be flood - prone. By 1969, the levee system surrounding the project area has been constructed, and by 1984, half of 7 Cultural Resource Support for the IHC Scott Proposed Bernhardt Gravel Mining Pit in Weld County, Colorado the project area is a tilled agricultural field; the two -track roads visible in the 1956 imagery have been replaced by the cultivated field and are no longer present. The cultivated field continues to expand, reaching its current shape in 1999, and the storage area on the southwestern margin of the project area is established by 2015. General Area History Weld County was first established in 1861, under the Territory of Colorado (Weld County 2023a). A majority of the county came to be settled by people of German descent who migrated from Russia in the early 1900s. These immigrants largely first worked on the railroad and in the sugar beet fields. The sugar beet industry began in 1902 with the establishment of sugar factories in Greeley and Eaton, and later in Windsor, Fort Lupton, and Johnstown. Weld County is currently the leading area for agricultural products in the state of Colorado and ninth in the United States; it is also the number -one -ranked county in the state of Colorado for cattle, grain, and sugar beet production (Weld County 2023a). Milliken, Colorado, began as a trading post in the 1860s and was recognized in 1905 as a railroad and agricultural community known as Hillsboro; by 1909, the Hillsboro community would begin to be overtaken by neighboring Milliken. The agricultural town has historically relied on sugar beets, alfalfa, potatoes, and ranching, as well as continued importing and exporting via the nearby railroad lines (Town of Milliken 2015). The project parcel (Parcel No. 105924000023) is zoned agricultural and owned by IHC. In 2022, Sunset Industrial acquired the property through Platte Land and Water LLC, which had transacted the property previously with Bernhardt Farms LLC, according to Weld County Clerk and Recorder records online (Weld County 2023b). One patent for the land containing the project area was filed by Henry Stevens and Jose Maria Saldano in 1867 under the Scrip Warrant Ad of 1855 (Accession number MW -0359-039) (BLM 2023). General research on Ancestry and other websites did not find any additional information pertaining to Henry Stevens or Jose Maria Saldano. RECONNAISSANCE SURVEY On March 6 and 7, 2023, SWCA 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, three cultural resources were newly recorded: one segment of a historic levee system (5WL9625.1), one prehistoric IF (5WL9626), and one historic IF (5WL9627). 5WL9625.1 SWCA newly recorded 5WL9625.1, a portion of a historic levee system, on March 7, 2023. The levee consists of a generally U-shaped earthen berm that bounds the eastern, southern, and half of the western margins of the cultivated field and project area. The berm averages 10 feet wide at the top, 20 feet wide at the base, and 5 feet high (Figure 4). There are several areas near the southeast and southwest corners, on the field -facing sides of the berm, with piles of concrete rubble. An unconnected portion of levee south and outside the project area has visibly been lined with concrete rubble, similar to riprap. 8 Cultural Resource Support for the lHC Scott Proposed Bernhardt Gravel Mining Pit in Weld County, Colorado Figure 4. 5WL9625.1, overview of levee from northeastern extent with South Platte River on left; view to the south. The levee first appears on aerial imagery from 1969 (NETROnline 2023). The adjacent levee appears between 1984 and 1999 and may correlate to the time period when the concrete rubble was added to the documented levee segment, perhaps with the intention of increasing or maintaining its structural integrity. No additional information was found pertaining to this resource. The site is not associated with significant events or people (NRHP Criteria A and B), nor does it represent significant or masterful architectural elements of design or materials (NRHP Criterion C). As an earthen berm built in the 1950s and 1960s, it is unlikely that the physical structure itself or historical research into the levee system will yield any additional and important information regarding the history of the region (NRHP Criterion D). The property lacks significance under any NRHP criteria. 5WL9626 SWCA newly recorded 5WL9626 on March 7, 2023. The prehistoric IF is on the shoulder and crest of a small rise at the foot of a prominent ridge system or upper terrace. Slopes range from 0 to 8 degrees with an east aspect. Vegetation is invasive and noxious weeds in the fallow tilled field, including Russian thistle and goatheads, allowing for 65 percent bare ground visibility. Surface sediment is alluvial and colluvial light brown sandy loam with some subrounded gravels. ST2 was excavated in the center of the IF (Table 4); one additional piece of quartzite fire -altered rock (FAR) less than 5 cm was recovered from the till zone in the top 13 cm of the shovel test. Impacts include erosion, tilling, and fence line construction. The IF consists of four artifacts in an area measuring 25 x 10 m: two refittable pieces of a metate (P1), one size class 5 tan chert primary flake, and two pieces of quartzite FAR less than 5 cm in size. P1 is 75 percent of a tannish -gray sandstone metate measuring 315 x 154 x 36 mm when refit (Figure 5). The metate is unifacially ground in a basin shape and gently U-shaped via flaked sides and dense pecking 9 Cultural Resource Support for the IHC Scott Proposed Bernhardt Gravel Mining Pit in Weld County, Colorado along all unground surfaces. The ground surface exhibits light pecking and faint unilateral striations along the long axis. Figure 5. 5WL9626, P1, metate, with tape at 30 cm. The IF does not meet any of the NRHP criteria. It is not associated with a significant individual or event, does not retain unique or significant characteristics, and does not have potential to retain significant subsurface deposits or to provide significant information on the history of the area. 5WL9627 SWCA newly recorded 5WL9627 on March 7, 2023. The historic IF is in the generally flat to slightly east sloping west -central portion of the fallow cultivated field. Vegetation consists of invasive and noxious weeds, including Russian thistle and goatheads, and allows for 65 percent bare ground visibility. Surface sediment is alluvial brown sandy loam with dense, coarse, poorly sorted gravels and some small cobbles. The IF consists of the bead of one aqua glass bottle finish. The finish is patinated and measures 1.5 inches in diameter. The IF does not meet any of the NRHP criteria. It is not associated with a significant individual or event, does not retain unique or significant characteristics, and does not have potential to retain significant subsurface deposits or to provide significant information on the history of the area. Shovel Tests Given the location of the project area on the Pleasant View Terrace, three shovel tests were excavated across the project area as part of the reconnaissance survey to assess the deposition and the potential for buried cultural material (see Table 4). Shovel Test 1 (ST 1) was placed in the northwest corner of the project area, outside the tilled agricultural field and nearest the river and levee. Shovel Test 2 (ST2) was placed in the northwestern portion of the project area, near the center of newly recorded prehistoric IF 5WL9626; more specifically, the test was placed upslope of a metate, near the transition from T3 to T4. 10 Cultural Resource Support for the /HC Scott Proposed Bernhardt Gravel Mining Pit in Weld County, Colorado Shovel Test 3 was placed in the south-central portion of the project area, in sediment representative of the majority of the matrix observed across the project area. Table 4. Shovel Test Results ST No. Depth Soil Profile Artifacts 1 Shovel 0-86 centimeters below surface (cmbs) 0-9 cobs: semicompact brown fine sandy loam with rootlets and poorly sorted subrounded gravels 9-15 cobs: semicompact brownish -yellow sand with small subrounded gravels 15-24 cmbs: semicompact brown sandy clay loam mottled with 20 percent pale yellow sandy loam; small subrounded gravels throughout 24-29 cobs: loose pale yellow sand with small subrounded gravels 29-55 cmbs: loose pale brown sandy loam with small subrounded gravels 55-86 cmbs: loose, coarse, pale yellow river bed sand with ample subrounded gravels None 2 Shovel 0-55 cmbs 0-32 cmbs: semicompact pale brown sandy loam with few small subrounded gravels 32-45 cmbs: compact pale yellowish -brown silty loam with 20% subrounded to subangular gravels 45-55 cmbs: compact pale gray silty loam with 20% small, subrounded gravels and calcium carbonates 0-13 cmbs: 1 quartzite FAR less than 5 cm (in plow zone) 3 Shovel 0-40 cmbs 0-22 cmbs: semicompact dark brown sandy loam with 30 percent poorly sorted, subrounded gravels 22-40 cmbs: very compact dark grayish -brown clay loam with 20 percent poorly sorted, subrounded gravels and some calcium carbonate lacing on peds None The reconnaissance survey and associated shovel tests confirm the field has been affected by plowing into the gravelly alluvium, effectively removing stable topsoil. No to few soil horizons remain within the cultivated field could support intact subsurface archaeological materials. The corners of the project area outside the agricultural field and disturbance areas exhibit clear alluvial bedding and have the potential to retain cultural horizons. CONCLUSIONS AND RECOMMENDATIONS Given the level of higher energy flooding and modern agricultural use occurring on this parcel, confirmed by the reconnaissance survey and shovel tests, either shallow or no native sediments that could retain precontact or early historic archaeological sites remain in the project area. Therefore, no additional archaeological assessment is recommended in the cultivated field. The northeastern portion of the project area, outside the cultivated field, is relatively undisturbed and has potential to retain buried archaeological material. One segment of a historic levee (5WL9625.t) and two IFs (5WL9626 and 5WL9627) were newly recorded within the project area. The three resources do not meet any NRHP criteria and are recommended not eligible for the NRHP. Therefore, work within the cultivated field will result in no historic properties affected, and no additional work is recommended. SWCA recommends that the undisturbed northeast corner of the project area is either avoided or monitored during initial excavations.
