Scale As Shown C - Sheet: Of: TYPICAL MINING SECTION DEWATERING JT-B1 -MW1 BORING / MONITORING WELL TRENCH SCALE IN FEET2 o N.T.S. 2 N d EXHIBIT D Mining Plan Mining Limits Calven Goza (Goza) proposes to mine the property located in the southwest 1/4 of Section 15, Township 5 North, Range 65 West of the 6th Principal Meridian, in the City of Greeley, Weld County, Colorado. The property is bounded by East 24th Street to the north, private property on the east, Colorado State Department of Highway and private properties to the south, and City of Greeley and private properties to the west. The land uses surrounding the property are agricultural, residential, and river corridor. The permit boundary will encompass approximately 55.77 acres which will all be affected acreage, and approximately 41.87 acres being mined. The remaining area will consist of access roads, and disturbed/undisturbed land. The following table depicts the different affected acreage: Affected Acreage Mining Plan Area (acres) Mined Area 41.87 Access Roads 0.97 Disturbed Land Adjacent to Mining Slopes 12.93 Undisturbed Land 0.00 TOTAL 55.77 Various setbacks from adjacent roads, adjacent structures, and oil and gas infrastructure will be maintained as mining occurs. All setbacks specified in the surface use agreements with the oil/gas companies will be followed. The final executed agreements are expected to be obtained in the near future and will be forwarded to the Division when they are available. A minimum 200- foot setback from any existing oil/gas facility will be maintained until that time. See Exhibit C, Mining Plan Map, and the Slope Stability Report for the mining limit configuration and information on setbacks and their locations. The 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. PDC Energy is the leaseholder and operator of the existing abandoned well that will be plugged and capped on the west side of the proposed mining area. We have also worked with Peterson Energy Operating, Inc. to provide this service at other mining permit locations for other operators. If PDC Energy does not want to perform this work, then Peterson Energy Operating, Inc. would be contacted to do it. They are licensed and bonded to obtain approvals from the Colorado Energy and Carbon Management Commission (ECMC) to do these types of re-plug services on abandoned oil and gas wells. Calven Goza la'Consulting,Inc. Goza Pit DRMS 112 Permit Application Products Sand and gravel will be the primary product produced from the Goza 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 Goza Pit property contains a significant commercial deposit of sand and gravel. The depth of interbedded sandy clays at the surface range from 2 to 8 feet. The thickness of the aggregate material ranges from 21 to 98 feet where bedrock contact occurs. Mining Methods The deposit will be dry mined after a slurry wall is constructed around the perimeter of the mining area. Mining will not expose groundwater prior to the slurry wall being constructed. 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 the 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 bottom of the active mining 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 where it will reach the South Platte River. The equipment and facilities may include, but are not limited to the following: Scaling Equipment A scale house and scale will be used to weigh trucks and product leaving the pit. The dimensions of the scale house are 40' x 12' and the scale will be 70' by 10'. The scale house will be founded on typical trailer type jacks and tiedowns on top of concrete pads with minimal rebar to provide reinforcement. The scale will also be founded on concrete pads with reinforcement where load cells are located for the scale. These foundations would be removed once the pit is fully mined. Processing Equipment Screens, wash plant, crusher, conveyors, stackers, and other miscellaneous processing equipment. All processing equipment will be mobile and temporary without fixed foundations. Washing will occur at the wash plant and excess water from the washing will be recycled to the wash water ponds within the processing area, there will be a sedimentation pond that will receive the excess water first and then and overflow from the sedimentation pond to the clear water pond for re-using the water and pumping back to the wash plant. Earth Moving Equipment Dozers, loaders, scrapers, excavators, and compactors will be used for mining and earth moving operations. Haul Roads and Access Roads Haul roads will be graded and constructed using the existing pit run where needed outside the processing area in order to move material from the mine using haul trucks, loaders, or scrapers. These roads will be mined and removed as the mining is completed. Access roads to the processing plant will be constructed with aggregates made at the site where the entrance to the permit boundary is located to the scale house and through the Calven Goza J&T Consulting,Inc. Goza Pit DRMS 112 Permit Application scaling area until the access reaches the stockpile locations. The roads around the stockpiles will be constructed from the existing pit run similar to the haul roads. 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. Topsoil will be stripped and salvaged from areas where overburden material will be stockpiled. 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. See the attached mining plan in Exhibit C for the stockpile locations. Mining of the aggregate will progress down to the underlying bedrock. Since reclamation will occur concurrently with mining, it is not anticipated that overburden material will be stockpiled long-term prior to use in production of road base. During mining, the mining the face will have a 3H:1V to 4H:1V slope to bedrock or the bottom of the future reclaimed reservoir. The processed aggregate material will be temporarily stockpiled near the portable processing plant. Recommendations for monitoring of slope stability, including, conducting a visual inspection of the excavated slopes on a weekly basis for the duration of mining, conducting a visual inspection after a major precipitation event that has saturated the ground using the same procedures, contacting qualified personnel to evaluate and recommend remediation work to stabilize the area in the event a visual inspection detects signs of potential slope failure, and if no visible signs of slope failure are detected during mining, reducing visual inspections to once every six months after mining completion, or after every major precipitation event. All local, State, and Federal rules and regulations will be followed for the storage and handling of any fuel for the facilities. Topsoil Handling Plan As stated previously the topsoil will be stripped to expose the aggregate product underlying the topsoil. The topsoil will be stripped using scrapers and stockpiled in the topsoil stockpile as depicted in Exhibit C. Topsoil will be stripped and salvaged from areas where overburden material will be stockpiled. The volume of topsoil is approximately 67,548 cubic yards. The depth of the topsoil is approximately twelve inches over the majority of the mining area. The topsoil will be stripped and stockpiled prior to mining operations. The volume of the overburden and clay material is approximately 1,826,336 cubic yards. This will be stockpiled as it is uncovered during the mining process. The height of the topsoil and overburden stockpile will be approximately 20 feet to 25 feet. Mine Phasing Goza anticipates mining and reclaiming 41.87 acres of the 55.77 acres within the permit boundary for the Goza Pit progressing as shown on the Mining Plan Map, there are 12.93 acres outside of the mining area that will be disturbed during the mining. The overall time required to complete the mining and reclamation is estimated to be 1 year and 1 month for phase la and 5 years and 10 months for phase 1 based on an average rate of 650,000 tons per year. The initial production is expected to be 300,000 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 MINI Calven Goza wiiA i J&T Consulting,Inc. Goza Pit DRMS 112 Permit Application could progress slower than anticipated and additional time may be required for mining and reclamation of the site. The mining will progress beginning at the outer edge where material will be moved toward the interior such that the mining slope can be established. The mining slope will be established for the entire perimeter in 3 to 6 feet intervals. Dewatering Dewatering trenches will be placed along the perimeter of each mining area. The dewatering trench around the perimeter of the phase being mined will be placed at the toe of the mining slope. As the phase is mined deeper the dewatering trench will be lowered and moved laterally along the mining slope toward the center of that phase. Slurry walls are anticipated to be installed around the perimeter of prior to exposing groundwater and mining will continue to commence in those phases and it is expected minimal dewatering will be required after the slurry walls are installed due to the slurry walls cutting off groundwater infiltration into the pit. Goza 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. MINI Calven Goza wiiA i J&T Consulting,Inc. Goza Pit DRMS 112 Permit Application EXHIBIT E Reclamation Plan Lined water storage reservoirs will be the final reclaimed use for the Goza Pit. Portions of mining area will be reclaimed as "native" areas, which will be re-seeded with native vegetation. The mining area 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 34.79 Access Roads 2.96 Reclaimed Vegetated Land (Disturbed Land 18.02 and Slopes above Reservoir Water Surface) Undisturbed Land 0.00 TOTAL 55.77 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 to three feet above the reclaimed normal water surface elevation. Design specifications and quality control procedures used during the construction of the slurry wall liner and clay liner will ensure that the reservoir meets the State Engineer's Office (SEO) performance standards for permeability. All reservoir slopes will be reclaimed to at least 3H:1V to 4H:1V final grade. Since reclamation will occur concurrently with mining, it is not anticipated that overburden material will be stockpiled long-term prior to use in production of road base. Scrapers and dozers and compactors will be used to shape the reclaimed slope material along the reservoir perimeters to achieve the final grade. 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. Calven Goza J&T Consulting,Inc. Goza 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 disturbed areas that are not within the reclaimed reservoir foot print. The backfill material will consist of gravel, overburden, clay, and topsoil from on-site materials. 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. The auger holes for the gravel investigation were backfilled with native gravel and soil cuttings from the drilling. The auger holes that were not backfilled were the four monitor wells that were constructed and permitted as permanent monitoring wells to monitor groundwater at the north, east, west, and south sides of the permit boundary. Monitor wells will remain on the property so the end user may continue to monitor levels of the groundwater elevations. 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. Topsoilinq Approximately the top twelve inches of soil on the property is classified as topsoil. This layer includes the root zone of grasses and crops, which will be stripped and stockpiled separately. Topsoil will be re-handled as little as possible and a Technical Revision will be submitted prior to re-locating topsoil stockpiles. 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. Prior to placing topsoil uneven areas and low spots will be graded to subgrade elevation, in addition debris, roots, branches, stones, in excess of 2 inch in size will be removed. Scarify surface to depth of 8 inches where topsoil is to be placed for a roughened condition to assist in eliminating erosion. Scarify/cultivate in areas where equipment used for hauling and spreading topsoil has compacted subsoil. Place topsoil during dry weather and on dry unfrozen subgrade. Remove vegetable matter and foreign non-organic material from topsoil while spreading. Grade topsoil to eliminate rough, low or soft areas. 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. A proper seedbed is firm and free of competing vegetation. Correct firmness is when an adult footprint is only slightly visible on the prepared bed prior to the seeding operation. The seedbed can be firmed, if needed, by pulling a commercial or homemade packer or roller. A firm seedbed is essential for proper seeding depth prior to using the mechanical seeder or broadcasting seed. Apply seed evenly in two MIN Calven Goza wiiA i J&T Consulting,Inc. Goza Pit DRMS 112 Permit Application intersecting directions. Rake in lightly. Apply seed at the vendor's recommended bulk seed rate/acre according to the quantity of PLS contained in their bulk seed to achieve the specified PLS/acre rate utilizing a mechanical seeder. Where access is limited and seed is applied by hand broadcasting, apply the seed mix at twice the PLS rate per acre and rake in once broadcasting in completed. Do not seed areas in excess of that which can be mulched on same day. Do not sow immediately following rain, when ground is too dry, or when winds are over 10 mph. Immediately following seeding, apply mulch to thickness of 1/4 inch. The seed mixture below was selected as recommended by Weld County for "Areas South of County Road 68". Reservoir side slopes below the anticipated reservoir water level will not be seeded. The proposed seed mix is shown in the following table. Reclamation and Temporary Stockpile Seed Mix Seed Species Scientific Name Application Rate* Mix (pls/acre) Western Wheatgrass Arriba, Barton, Rosana 2.50 Blue Grama Hachital, Lovington 1.50 Vaughn, Butte, Niner, El Sideoats Grama Reno, Haskell 2.25 Grasses Sand dropseed 0.25 Calibra or Garibaldi Perennial Ryegrass tetraploid 0.75 Slender Wheatgrass Pryor, Revenue or San Luis 2.50 Alkaligrass Fults II, Salt on Sea 1.25 Switchgrass Bebraska 28, Blackwell 1.00 *Application rate is for drilling the seed. 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. Ideal seeding dates for Colorado are November 1 to May 1, when the soil is not frozen. Grasses should be seeded when soil moisture and temperature are optimum for germination. Grasses are designated either "cool" or "warm" season based on their growth cycle. Cool-season grasses can be planted when temperatures are cooler and day lengths are short. Warm-season grasses need warmer temperatures and longer day lengths to grow. Refer to Weld County's seeding recommendations as a resource for time frames outside of the ideal seeding times at www.weld.gov/Government/Departments/Public-Works/Weed-Management/Controlling- Weeds/Reseeding. 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. See Exhibit J for specifics of the weed control plan. Calven Goza A I la'Consulting,Inc. Goza Pit DRMS 112 Permit Application 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, Goza 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 ditches in necessary areas to maintain groundwater levels during the mining, and a perimeter drain if needed to convey groundwater around the lined reservoir after the pit side liner is installed. A ground water model by McGrane Water Engineering, LLC has also been provided and the results indicate that water levels will be affected by +/-0 to 1 ft and the wells within the predicted water level change are in the mounded area so the overall impact of the slurry wall and clay liner will be insignificant and not noticeable because the depth to groundwater is greater than 30 feet at those well locations. Goza proposes that they monitor groundwater levels through both interior (within phases of the mining) and exterior (outside the slurry wall lining) monitoring wells that they have installed, or have access to before, during, and after the mining and reclamation is complete so that impacts to the groundwater table, from this mining operation, can be identified and addressed. It is the intent of Goza 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 1 year and 1 month for phase la and 5 years and 10 months for phase 1. 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: Phase Acreage Time Frame to Complete and Reclaim 1 a 41.87 acres 1 year and 1 month 1 41.87 acres 5 years and 10 months The assumed annual production rate is 300,000 tons initially to 1,000,000 tons maximum for processed material leaving the mine each year. The size and area of reclamation varies but Calven Goza J&T Consulting,Inc. Goza Pit DRMS 112 Permit Application generally consists of the outside mining slope being reclaimed at a 3H:1V to 4.H:1V slope with the addition of topsoil and revegetation.

The proposed mining site is located approximately 800 feet east of Cherry Avenue, is adjacent to East 24th Street on the north side, and is adjacent to the Madison Lake on the south side of the site. US Business 34 is approximately 2,100 feet to the east of the permit boundary. Access to the site will be located at the northeast corner of the permit boundary off of East 24th Street. The dominant land use surrounding the property is residential, agricultural, and recreational. The operation will consist of sand and gravel production and will not impact the South Platte River in the form of depletions due to a slurry wall that will be installed prior to mining. Mining of the Goza Pit site will last for approximately 6 years and 11 months. Once reclamation is complete, the water storage reservoir will be created with a total surface area being 34.79 acres. The depth to groundwater ranges from 5 to 9 feet within the permit boundary (measured in MW- 1 through MW-4, See the attached piezometer measurements table). The site will be mined down to a depth of 35 to 88 feet thus exposing groundwater to the atmosphere. This exposed groundwater, along with the operational losses associated with the extraction of sand and gravel deposits, will impact the South Platte alluvial aquifer. These impacts will cause river depletions that must be augmented. Groundwater will be exposed during the mining once the mining depths reach an elevation of approximately 4622 feet. To enable dry mining at the Goza Pit mining site, there will be dewatering trenches around the bottom of the mining slope. These dewatering trenches will change in length throughout mining. The maximum length will occur when the cell is completely mined, but before the reclamation has begun. The maximum size of dewatering trench will be 4,900 feet long and 5 feet wide, or 0.56 acres of exposed surface area. The 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 to account for additional groundwater being exposed. The gravel pit will have a slurry wall liner constructed prior to the commencing of mining. Water Requirements Water use at the Goza Pit mining site will include evaporation from exposed groundwater, dust control of haul roads and stockpiles, water for the wash plant (i.e. wash screen for concrete rock and sand) 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 Goza Pit mining site will include groundwater exposed in the dewatering trenches. The Calven Goza J&T Consulting,Inc. Goza Pit DRMS 112 Permit Application maximum exposed surface area at the site during mining is estimated at 0.56 acres. Goza 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 through 2025) was used. The long-term average precipitation at the Ogilvy River Farm Pit mining site is estimated at 14.15 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 35.09 inches or 2.92 feet. The maximum annual evaporative loss from the 0.56 acres is 1.64 ac-ft. Operational Loss The average annual production from the Goza Pit mining site is estimated at 650,000 tons. Using 4% moisture content, (2% for moisture in the product and 2% for water used to wash), the total associated consumptive use for water retained in the material mined and water used for washing is 0.18 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 7.58 ac-ft. Consumptive Use The maximum annual consumptive use (operational loss + evaporation loss) at this site during the mining operation is estimated to be 9.22 ac-ft. Replacement Water The replacement of consumptive uses at the site 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 1 Well Permits in the Goza Pit — Groundwater Evaluation by McGrane Water 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. Table G-1 below is a corresponding list of wells as numbered in the Ogilvy River Farm Pit — Groundwater Evaluation by McGrane Engineering, LLC that is attached that are within 600 or more feet of the mining limits that were within the +/- 1 foot mounding area on the west and east side of the pit. Calven Goza J&T Consulting,Inc. Goza Pit DRMS 112 Permit Application Table G-1 - Permitted and Decreed Wells Within 600 Feet or Area of+/- 1 foot mounding not owned by Goza Map Permit Structure Zip ID No ID Well Name Owner Address City State Code Franklin L 1410 E 24th 1 174821 Domestic Roy Street Greeley CO 80631 Richardson, 1846 Cherry 2 97511-A Domestic B R Ave. Greeley CO 80631 Scheopner, 2101 E 24th 3 275897 Domestic David H Street Greeley CO 80631 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 Goza Pit mining site results in material injury to surrounding wells, Goza 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 Goza 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 Goza will monitor the groundwater levels surrounding the site and provide groundwater recharge, if necessary, via perimeter ditches/ponds. Goza will construct these ditches/ponds in the locations where direct discharge to an existing adjacent irrigation lateral is not available to ensure that stabilized groundwater levels are maintained. They will discharge dewatering flows into existing adjacent irrigation laterals where possible to limit the disturbance to the surrounding land. A slurry wall liner is proposed around the mine and will likely be installed prior to the mining starting. To summarize the mitigation process, as the mining/dewatering occurs, Goza will monitor the groundwater levels adjacent to mine as the mining progresses. If groundwater levels drop to a level that prevents an adjacent well from performing acceptably, according to that well's owner, Goza 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. Calven Goza J&T Consulting,Inc. Goza Pit DRMS 112 Permit Application Groundwater wells that are not owned by Goza 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, Goza will either obtain a well waiver from the owner of the well, or provide an agreement with the well owner that Goza will mitigate and material damage to the well that is directly attributable to the mining and reclamation of the site. All other wells within 600 feet of the mining limits are either owned by Goza, 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 Goza has either installed or has access to, and the groundwater level data that has been collected for each well. The groundwater monitoring data will be provided for what has been done to date with this permit application and then submitted in the annual report for the pit to the DRMS after approval of the permit application. Groundwater Quality Monitoring Plan The majority of the mining operations at this site will be within the slurry wall lined area. The areas outside of the slurry wall will be limited to the scale house and haul roads for trucks coming into and out of the pit, which are not likely to affect groundwater quality. To establish pre-mining groundwater quality at the site Goza will have four monitor wells sampled quarterly. The samples will be taken by a qualified consultant and then tested by Eurofins Laboratories for the analytes listed in Tables 1-4 of the "Basic Standards for Groundwater." Once the baseline has been established, we would recommend annual sampling to monitor the groundwater quality and a technical revision will be submitted to request the change. The quarterly sampling will continue until 5 quarters of data has been established. Once the baseline has been established, we would recommend annual sampling to monitor the groundwater quality and a technical revision will be submitted to request the change. Goza commits to establishing points of compliance following five quarters of baseline monitoring. Monitor Well 1 located on the west side of the permit boundary will be used as a background water quality sampling location and the remaining three monitoring wells as points of compliance (POC), the POCs will be Monitor Wells 2, 3, and 4. When obtaining a monitor well sample typically at least 3 well volumes will be taken from the well to make sure a true groundwater sample is obtained. During the purging time, measuring pH, temperature, EC will occur at different times until stabilization occurs. Then the sample will be collected and placed in the lab provided bottle(s) for unfiltered samples. The sample will then be filtered prior to placement into the lab bottle(s) for Eurofins to run the testing on for the dissolved metals from Table 41. Sampling and collection of the groundwater from the monitor wells will reference the USGS National Field Manual for Collecting Water Quality Data Chapter A.4 Collection of Water Quality Samples and EPA Region 9 Groundwater Sampling Guide. Calven Goza J&T Consulting,Inc. Goza Pit DRMS 112 Permit Application The groundwater quality sampling data will be provided for what has been done to date with this permit application/adequacy review. and then submitted in the quarterly report for the pit to the DRMS after approval of the permit application. Goza will notify the DRMS within 7 days of receiving a lab report that indicates any of the standards set forth in Tables 1-4 have been exceeded. If a lab report shows an exceedance, a new sample will be taken to verify exceedance or discount potential lab contamination. The groundwater quality testing data will be provided for what has been done to date with this permit application/adequacy review and then submitted at the following frequency to the DRMS: First quarter report due by May 1st of every year. Second quarter report due by August 1st of every year. Third quarter report due by November 1st of every year. Fourth quarter report due by February 1st of the following year. The report will include a site map with well locations, tabulated data for all parameters, graphs/plots of selected parameters, a narrative analysis of the data with any trends and/or anomalies identified, and graphs and tables of measured groundwater levels for all locations.

Job ID: 280-212424-1 Project: Quarterly Monitoring Wells- Goza Goldman Property Job ID: 280-212424-1 Eurofins Denver Job Narrative 280-212424-1 4 The analytical test results presented in this report meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary Page, unless otherwise noted. Data qualifiers and/or narrative comments are included to explain any exceptions, if applicable. Regulated compliance samples(e.g. SDWA, NPDES)must comply with associated agency requirements/permits. • Matrix-specific batch QC (e.g., MS, MSD, SD)may not be reported when insufficient sample volume is available or when site- specific QC samples are not submitted. In such cases, a Laboratory Control Sample Duplicate(LCSD)may be analyzed to provide precision data for the batch. • For samples analyzed using surrogate and/or isotope dilution analytes, any recoveries falling outside of established acceptance criteria are re-prepared and/or re-analyzed to confirm results, unless the deviation is due to sample dilution or otherwise explained in the case narrative.

Job ID: 280-215977-1 Project: Quarterly Monitoring Wells- Goza Goldman Property Job ID: 280-215977-1 Eurofins Denver Job Narrative 280-215977-1 4 The analytical test results presented in this report meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary Page, unless otherwise noted. Data qualifiers and/or narrative comments are included to explain any exceptions, if applicable. Regulated compliance samples(e.g. SDWA, NPDES)must comply with associated agency requirements/permits. • Matrix-specific batch QC(e.g., MS, MSD, SD)may not be reported when insufficient sample volume is available or when site- specific QC samples are not submitted. In such cases, a Laboratory Control Sample Duplicate(LCSD)may be analyzed to provide precision data for the batch. • For samples analyzed using surrogate and/or isotope dilution analytes,any recoveries falling outside of established acceptance criteria are re-prepared and/or re-analyzed to confirm results, unless the deviation is due to sample dilution or otherwise explained in the case narrative. Receipt The samples were received on 10/28/2025 11:09 AM. Unless otherwise noted below,the samples arrived in good condition,and, where required, properly preserved and on ice. The temperature of the cooler at receipt time was 0.9°C. Receipt Exceptions For the following sample,the 250 mL amber glass container preserved with Sulfuric acid and the 250 mL plastic container that was unpreserved were received with their lids switched: MW-3(280-215977-4). No corrective action required. Method 200.7 Rev 4.4-Metals(ICP)-Dissolved Samples MW-1 (280-215977-1), MW-2(280-215977-2), MW-4(280-215977-3)and MW-3(280-215977-4)were analyzed for Metals(ICP)-Dissolved. The samples were prepared on 10/29/2025 and analyzed on 10/30/2025. Method 200.8-Metals(ICP/MS)-Dissolved Samples MW-1 (280-215977-1), MW-2(280-215977-2), MW-4(280-215977-3)and MW-3(280-215977-4)were analyzed for Metals(ICP/MS)-Dissolved. The samples were prepared on 10/29/2025 and 11/13/2025 and analyzed on 10/30/2025 and 11/17/2025. The continuing calibration verification (CCV)associated with batch 280-720511 recovered above the upper control limit for Iron. The samples associated with this CCV were non-detects for the affected analyte;therefore,the data have been reported. Associated samples: MW-3(280-215977-4)and (CCV 280-720511/51). The matrix spike/matrix spike duplicate(MS/MSD)recoveries for preparation batch 280-720230 and analytical batch 280-720511 were outside control limits for one or more analytes. See QC Sample Results for detail. Sample matrix interference and/or non- homogeneity are suspected because the associated laboratory control sample(LCS)recovery is within acceptance limits. The matrix spike/matrix spike duplicate(MS/MSD)recoveries for preparation batch 280-720230 and analytical batch 280-720511 appear outside control limits for Arsenic. See QC Sample Results for detail.This is due to carryover from a high sample before the parent sample.The spike amount is 40 ppb Arsenic and the MS and MSD recovered approximately 40 ppb. (280-215977-A-1-F MSD) Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate(MS/MSD)associated with preparation batch 280-722700. The laboratory control sample(LCS)was performed in duplicate(LCSD)to provide precision data for this batch. Method 245.1 -Mercury(CVAA)-Dissolved Samples MW-1 (280-215977-1), MW-2(280-215977-2), MW-4(280-215977-3)and MW-3(280-215977-4)were analyzed for Mercury(CVAA)-Dissolved. The samples were prepared on 10/29/2025 and analyzed on 10/30/2025. Method SM 2540C-Solids,Total Dissolved (TDS) Samples MW-1 (280-215977-1), MW-2(280-215977-2), MW-4(280-215977-3)and MW-3(280-215977-4)were analyzed for Solids, Total Dissolved (TDS). The samples were analyzed on 10/30/2025. Method 300.0-Anions, Ion Chromatography-Dissolved Eurofins Denver Page 5 of 30 11/17/2025 Case Narrative Client: J&T Consulting, Inc.

Lupton, CO 80621 RE: Goza Pit—Groundwater Evaluation Dear Mr. York: The proposed Goza Pit is located approximately 1 mile east of Greeley, Colorado in Section 15, Township 5 North, Range 65 West (6th PM). The site is located on the north side of the South Platte River(SPR) on the northeast corner of E 26th Street and Cherry Avenue. Figure 1 shows the proposed pit boundary, the study area (-24 square miles)where data was collected, and the model area(-10 square miles). The study area includes approximately 260 permitted and constructed water wells with usable well data per the State's well database (CDWR, 2025). The model area extends from the SPR in the center of Section 21 (TSN, R65W)to just north of the Poudre River in Sections 1-5 (T5N, R65W). 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 impact of a clay "liner" or slurry wall around the proposed pit. Impacts typically include a rise in the water table ("mounding") on the up-gradient side of the liner 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 lower well yields if the decline is more than approximately 10 percent of the aquifer saturated thickness. GROUNDWATER INVESTIGATION To evaluate the groundwater level changes in response to the liner installation, we: 1. Reviewed existing published groundwater literature of the area; 2. Compiled well data from the State's Well database (CDWR, 2025) 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 well permits and pit site test hole and monitoring well drilling data; 4. Compiled monitoring well data in Table A2 from monitoring wells drilled by CMT Technical Services in May 2025 and measured by J&T. 5. Created a MODFLOW groundwater model to evaluate changes in groundwater levels resulting from a liner installed around the pit; and Goza Pit Groundwater Evaluation November 2025 Page 2 of 38 6. Documented the data, our assumptions, modeling results, conclusions and a discussion of parameter and model uncertainty in Appendix A- Groundwater Evaluation and Modeling. Results Summary We used the USGS MODFLOW2000 (Harbaugh et al, 2000)modeling program and the Groundwater Vistas (version 8) Groundwater Users Interface (GUI) to prepare model files and evaluate the results. Using reasonable aquifer properties and boundary conditions discussed below, we determined that mounding greater than 0.5 feet(but<1.0 feet) extends approximately 500 feet to the west(up-gradient), and shadowing between-0.5 and-1.0 feet approximately 1,000 feet to the north and 500 feet to the east, as shown on Figure A10. In general, mounding and shadowing impacts are buffered by: i)two unlined ponds located just south of the pit on either side of Hwy 34 and ii) a strong hydraulic connection between the aquifer and SPR. There are three registered domestic wells within modeled shadow area as summarized in Table 1.

We do not believe the predicted change in water table+/- 1 foot will be noticeable to the homeowners listed in Table 1 due because natural fluctuations associated with seasonal river stage and drawdown effects of nearby agricultural and domestic pumping wells. There are no registered wells (and therefore homes) located within the mounding area shown in Figure A10 which means there is no chance that any rising water levels on the upgradient side will threaten any property structures. Recommendations We recommend that the applicant: 1. Confirm the location of the SEO wells show on Figure A10 and listed in Table 1; 2. Confirm there are no vulnerable structures located within the upgradient mounding area shown in Figure A10; 3. Continue to monitor existing monitoring wells; 4. In the future, make note of when the Canal 3 Ditches and Patterson Ditch start and stop diverting and evaluate seasonal water table fluctuations prior to and after pit construction to attempt to discern between changes in water levels caused by the pit verses seasonal changes caused by the South Platte River and nearby ditch recharge.

DATA AVAILABLE 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 • Geologic logs from four monitoring wells and six additional boreholes and installed around the pit in May, 2025. These maps are plotted in Figure Al. The well data compiled in Table Al (at end of report). Registered Wells The main purpose of this study is to evaluate whether there will be any impacts to the 440 registered and constructed(not abandoned)wells within our study area. Well Use Well use is important because some wells can be more impacted by the pit than others. Most of the registered wells shown on Table A2 are used for irrigation, domestic and commercial uses as shown in the table below. "Monitoring and Sampling"wells cannot be "impacted"by the mine because they simply exist to monitor groundwater levels and sample. Table A2-Registered Wells Well Type Amount Well yields are typically not impacted if water levels Commercial 14 rise since an increase in water levels will cause a Domestic 192 slight increase in pumping rates. Well yield will Household use only 29 only significantly drop if there is a significant drop Irrigation 83 in water levels in the magnitude of approximately 10 Industrial 3 percent of the aquifer saturated thickness. The Monitoring/Sampling 99 purpose of defining the change in water levels in the vicinity of the pit is to evaluate this possibility. If Municipal 1 we exclude the 99 monitoring wells, there are Stock 6 approximately 331 (440-99)registered wells that can Fire 1 be potentially impacted in our study area.

Compiled data in Table Al includes: the permit number,well owner, PLSS location, USGS Digital Elevation Model(DEM) elevation, registered use, well depth, depth to bedrock, yield in gallons per minute (gpm), reported static water level (SWL) and McGrane Water Engineering,LLC 1669 Apple Valley Rd. • Lyons,CO 80540 •Phone: (303)917-1247;email:dennis@mcgranewater.com Goza Pit Groundwater Evaluation November 2025 Page 5 of 38 calculated water table elevation. Well statistics including use, depth and yield are shown at the bottom of Table Al and discussed below. Figures la, lb, lc, and ld are zoomed-in versions of each quartile of Figure 1, that show more detailed locations. When evaluating well impacts (report Table 1), we compared modeled water level changes to all registered wells within the two sections (2 square miles)nearest the mine as shown in Figure A9. Monitoring Well Data Table A3 shows monitoring well elevation and depth to bedrock data transcribed from CMT Technical Services drilling logs (CMT, May 2025). The depth to bedrock ranges from 35 feet on the south side of the pit to approximately 95 feet on the north side. Table A3 also shows monthly water level data compiled by J&T. The shallowest depth to water was measured in August 2025 for MW-2 at 4.92 feet from top of ground(ft-tog). The deepest level measured was at 7.35 ft-tog measured at MW-1 in November 2025.

All water levels then dropped between August and November. The maximum decline was between August and November occurred in MW-2 (-2.42 ft). We expect the maximum fluctuations to be approximately 3-feet between the seasonal high in August and the seasonal low in approximately March or April the following year when the SPR stage is lowest. HYDROGEOLOGY We relied heavily on the Keller and Morgan (2020) surficial geologic mapping and aquifer parameters from the South Platte Decision Support System (SPDSS)project(CDM, 2006 and 2013) conducted by the Colorado Water Conservation Board. The hydrogeology of the SPR alluvial aquifer is also described by the US Geological Survey, Smith and Others (1964), Hurr and Schneider(1972), Robson (2000) and Lindsay and Others (1998 and 2005). Surficial Geology Figure A2 shows 1:24,000 scale surficial geology prepared by the Colorado Geological Survey (Keller and Morgan, 2020). The alluvium within the study areas consists of sand and gravel alluvial deposits (geologic map symbols Qal -Qa3 youngest to oldest). The pit will be located McGrane Water Engineering,LLC 1669 Apple Valley Rd. • Lyons,CO 80540 •Phone: (303)917-1247;email:dennis@mcgranewater.com Goza Pit Groundwater Evaluation November 2025 Page 6 of 38 primarily within the Qa2 and Qa3 which are described as containing stratified beds of sand and gravel exposed in both the Cache la Poudre (CLP) and South Platte River(SPR)valleys. Wind-blow dune sand and loess (fine silt and sand) deposits (Qe and Qes) are in contact, and sometimes overlay the floodplain alluvium. Collectively, multiple terrace levels of unconsolidated sediment occur over bedrock. The underlying bedrock surface represents a palechannel incised into gray claystone (CMT, 2025) which is likely the Laramie Shale Formation (Kb). Decomposed shale in the form of"clay" is often logged above shale bedrock in drilling logs. The link on right side of Table Al can be used to access well permit and completion data, including drillers' logs. Well Depth Well depths are deeper within a paleo-channel that extends from the southwest to northeast model areas. The depth to bedrock from 130 wells within the study area ranges from 10 to 118 ft (Table Al). The depth to bedrock within the pit ranges from 35 to 95 ft(Table A3). Figure A2 shows the spatial distributions of wells and their depths. Bedrock Elevation Contours Figure A3 shows combined elevation contours of the top of bedrock digitized from the SPDSS bedrock surface (CDM, 2013). The SPDSS maps were made based on Robson and Others (2000) and Hurr and Scheider(1972). We modified the contours based on wells drilled after 2007 (colored red) and the Goza pit boring and monitoring wells (Table A2). The map shows that the SPR paleochannel enters the model study area from the southwest and extends under the CLP river in the northeast. The southeast side of the pit has shallower bedrock elevations based on the boring logs (Tables Al, A3 and CMT, 2025)which creates a structural bedrock high southeast of the pit. We are uncertain whether the high bedrock significantly affects groundwater levels in the vicinity of the pit. Water Level Contours We created a water table map (Figure A4) that reflects average water table conditions using available data from registered SEO wells (Table Al) and Goza monitoring wells measured on July 7, 2023 (Table A2). The reported static water level depths for 153 wells ranges from 2 to 55 feet and averages 23 ft(Table Al). We calculated the contoured water table elevations by subtracting the reported depth to water from well site elevations interpreted from US Geological Survey l Om Digital Elevation Model (DEM) data sets and then contoured the resulting data set. The pit monitoring well elevations were surveyed by J&T. The water table map was imported into the model and used to evaluate modeled contours. We will discuss this comparison in greater detail under the "Model Boundary Conditions" section below and under"Model Results." Water Level Fluctuations The water table within the South Platte and Poudre River alluvial aquifers can fluctuates up to 7 feet in response to seasonal recharge and agricultural pumping and return flows (Arnold and Others, 2010, p. 12 and Barkmann and Others, 2014). The water table is highest in the summer and early fall, likely as the result of increased aquifer recharge from irrigation, seepage from unlined ditches, and greater precipitation. J&T began monthly monitoring of the four Goza monitoring wells in July 2023 so the data set is still incomplete. However, over the past 5 years, J&T has been monitoring seasonal fluctuations in the vicinity of the Derr and DPG pits located approximately 4-5 miles east of the pit. There, seasonal water level fluctuations range from 0 to 3 feet which we believe is likely also characteristic of this location.

When flowing, ditch leakage likely causes a seasonal rise in the water table. We do not know whether there is simply a vertical seepage gradient that won't be affected by the lined pit, or whether mounding could reduce ditch seepage or potentially mitigate mounding by absorbing the rise in the water table as a gain to the ditch. For this groundwater modeling exercise, we ignored the ditch's potentially mitigating effects to provide a worst-case simulation for evaluating impacts to well users. However, we recommend that the operator monitor ditch start and stop dates in the spring and fall and attempt to differentiate water level fluctuations caused by ditch seepage verses pit mounding and shadowing. Saturated Aquifer Thickness We calculated the aquifer saturated thickness as the difference between the water table (Figure A4) and the top of bedrock(Figure A3). Figure A5 shows how the saturated thickness is thickest(50 to greater than 80 feet)within the SPR paleochannel. Away from the SPR paleochannel, the aquifer saturated thickness thins to 20 to 40 feet. 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 168 wells range from 1 gpm(domestic well)to 1,500 gpm for irrigation. Well yields from domestic wells are less than 15 gpm. Agricultural irrigation wells (yellow and blue squares) are scattered throughout the study area and typically range from 250 gpm to up to 1500 gpm. 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 State used 650 ft/day for this area of the SPDSS model (CDM, 2006, Fig. 7a). By selecting a constant hydraulic conductivity value of 650 ft/day for the model, the computed transmissivity (gpd/ft) within the SPR paleochannel ranges from 300,000 to 488,000 gpd/ft. Where the aquifer thins away from the paleochannel, the transmissivity drops to below 100,000 gpd/ft. Unlined Ponds There are two unlined ponds located immediately south of the Goza pit, one on either side of Hwy 34. Since they are unlined, they are likely in hydraulic connection with the aquifer and SPR. As such, the ponds could: 1)mitigate the effects of mounding by allowing water to enter the ponds instead of raising the water table; and 2)buffer downgradient affects by increasing the gradient and therefor flowing into the "shadow" area. In effect, the pond will act like a drain that moves mounding water around the lined pit to mitigate mounding and shadowing affects. We therefore will include the unlined ponds as features in the groundwater impact model. MODELING We used the Groundwater Vistas pre- and post-processor(version 8.30 Build 87, Rumbaugh, Environmental Solutions, Inc.) to construct and run a MODFLOW2000 (Harbaugh et al, 2000) model and display the results. We then exported head and drawdown values to create water level and mounding maps and cell-by-cell flow terms to evaluate the mass balances (breakdown McGrane Water Engineering,LLC 1669 Apple Valley Rd. • Lyons,CO 80540 •Phone: (303)917-1247;email:dennis@mcgranewater.com Goza Pit Groundwater Evaluation November 2025 Page 8 of 38 of inflow and outflow components) of each model run. We utilized ESRI ArcView GIS software to process and prepare report figures. Model Boundary Conditions The model boundaries include the model sides, top and bottom. The entire model sits within the SPR and CLP alluvial aquifer on all sides. The model extends south of the SPR and north of the CLP river. The model area is 13,800 feet from north to south and 21,200 feet wide (west to east). The model consists of one layer, 69 rows and 106 columns, and has 200-foot square model cells. The bottom bedrock elevation surface (Figure A4) was digitized in ESRI GIS software and imported into the model on a 200 ft grid. Aquifer inflow and outflow occur through Constant Head(CH) cells that establish a fixed gradient. Due to the large data set of wells drilled over many decades, we believe this represents "average" aquifer water level conditions. We assigned CH elevations around the model perimeter using the water table contour map Figure A3. The highest groundwater elevation(4710 ft) is in the western-central portion of the model (near central Greeley)between the SPR and the CLP river, and the lowest elevation (4600 ft) is in the southeast corner. Therefore, the water table drops 110 feet from west to east which represents an average 0.005 gradient. The model boundaries are far enough away from the pit so that the mounding does not significantly affect alluvial aquifer inflows and outflows as discussed in the Mass Balance section below. River Simulation MODFLOW"River" cell stage elevations were assigned to all model cells along the SPR and CLP rivers. River cell elevations were assigned using the point at which the 10-ft water table contours crossed the stream and were interpolated and assigned in between by the model software. The western-most and eastern-most SPR river cells were assigned elevations of 4630 ft(ms1) and 4609 ft, thereby dropping 21 feet, a 0.0016 gradient(ft/ft). The CLP "River" cells were assigned an elevations of 4632 ft(ms1) and 4600 ft thereby dropping 32 feet which is a gradient of approximately 0.0019 ft/ft. 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 vertical hydraulic gradient. A high level of connection between the rivers and aquifer mitigates impacts by allowing water to freely flow between the river and aquifer. 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) determined the streambed permeability on either side of the Goza pit(sites SC-08 and SC-14) have a vertical hydraulic conductivities (Ksb)ranging from 137 ft/day to 506 ft/day. We believe this rate is too high and too close to the horizontal K(Kh) value of 650 ft/day reported for the area and used in the SPDSS model in this area. Pumping 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 used a Ksb of 36 ft/day to reduce the connection to the river. This assumption creates a conservative "worst case" scenario for evaluating pit impacts.

This resulted in a COND value of 1,128,000 ft^2/day in the model as shown in the table below. MODFLOW River Cell Parameters Streambed COND *Width (ft) Length (ft) Conductance Ksb/m (ft^2/day) (day^-1) 157 200 36 1128000 The flow from the river in or out of river cells 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 river and the aquifer. Unlined Ponds We simulated the unlined ponds located immediately south of the Goza pit(on either side of Hwy 34) using Constant Head(CH) cells. Based on USGS DEM data, we assigned the south pond an elevation of 4625 feet and north pond 4624 feet. We believe the hydraulic connection to the aquifer is much less than the SPR due to silt buildup on the pond bottoms. To simulate this, we reduced the hydraulic conductivity of the cells containing the ponds to 5 ft/day(representative of silt). We feel this is a reasonable approach to modeling the ponds which create a limited connection at a constant level. We do not know what month the DEM elevations were determined, so we do not know whether they represent "average" levels, However, the DEM elevations are very close to the average measured elevations of MW-1 (elev. 4624 ft) on the west side of the pit and an elevation of 4622 ft at MW-4 located on the east side of the pit. Model Results We conducted two model runs to evaluate groundwater level changes caused by the Goza pit liner. Pre-liner Run The initial run(Goza_SS7) represents the pre-liner conditions. Figure A8 shows the modeled water table contours (blue) compared to "target" contours (white). In this run the pit cells are "on"which allows water to flow through them. The contours show close agreement in the western half of the model, but the modeled blue contours plot more east in the pit vicinity. This implies modeled water levels are slightly higher than observed levels in the middle of the model in the vicinity of the Goza pit. To look at this more quantitatively, we compared measured verses modeled water levels graphically and statistically in the section below. Observed vs. Modeled Heads and Residuals Calibration is the process where we compare measured water levels to modeled water levels in terms of their elevation in feet above mean sea level (ft-msl). We then modified model boundary conditions and parameters (inflow and outflow constant head elevations and aquifer permeability(hydraulic conductivity) to achieve a closer match. In the figure and table below, we compare observed and modeled(pre-pit run"Goza_SS7")water levels from Table A2 (311 observations).

The best fit dashed line shown above has an RA2 of 0.70 due to the generally higher modeled levels. The highlighted Root Mean Squared(RMS) error is 8.22 ft. The Root Mean Squared(RMS) error is the square of the difference between the observed and modeled values (aka"residual"). We removed approximately 12 data points highlighted in red in Table Al where the difference between measured and modeled levels were greater than+/- 30 feet with the assumption that the measurements or DEM ground elevations were spurious. We feel any RMS less than 10 ft is reasonable considering the well data is from over a 50-year time period and seasonally variable (ie. will likely fluctuate over 3 feet just based on the season). If we focus on just residuals of the 8 monitoring wells around the pit, the RMS drops to approximately 3.6 ft. We did not attempt to change the lined pond elevations or hydraulic conductivity to improve the calibration statistics. The residual distribution is shown on Figure A8. There appears to be a random distribution of higher and lower values throughout the model area which suggests that our modeled heads are reasonable throughout the model despite apparent differences in the contour lines. Mass Balance Table A3 (end of report) shows the model mass balance results(Run: Goza_SS7)which compares inflow and outflow components. The total aquifer inflow across the north, south and west sides of the model is 18.12 cfs while aquifer outflow to the east is approximately 5.94 cfs, resulting in river gains for both the SPR and CLP of approximately 12.18 cfs (18.12-5.94). The gain of approximately 12 cfs over approximately 6 miles (including both rivers) is approximately 2 cfs per mile. The mass balance error is 0.0001% 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. Water Level Changes Caused by the Goza Liner In run<Goza_SS8>, we turned the pit model cells off and used the output heads from the pre-pit run<Goza_SS7>run as starting heads. Figure A9 is the contoured"difference" in model output heads between the post-pit run minus pre-pit run determined using GIS grid-math techniques.

The maximum mounding on the upstream side and shadowing on the downgradient side is less than +/-1.0 feet. The +/- 0.5 ft contour extends approximately 500 feet upgradient and 1,000 feet downgradient. Table A3 (end of report) also shows the model mass balance result of run Goza_SS8). With the pit cells off, the total river gain is 11.98 cfs which is 0.2 cfs less than the pre-pit run (Goza_SS7) discussed above. Therefore, the pit's effect on surface water gains at this location is minimal.

We do not believe the predicted change in water table+/- 1 foot will be noticeable to the homeowners listed in Table 1 due because natural fluctuations associated with seasonal river stage and drawdown effects of nearby agricultural and domestic pumping wells. There are no registered wells (and therefore homes) located within the mounding area shown in Figure Al which means there is no chance that any rising water levels on the upgradient side will threaten any property structures. Model Sensitivity The modeled effects of the lined Goza pit are insensitive to the hydraulic conductivity (K) of the aquifer. A decrease in K causes a proportional decrease in model inflows, but the mounding and shadowing effect remains the same due to the lower permeability connection to the SPR. The opposite relationship occurs if the aquifer K is increased which results in additional aquifer inflow but the mound remains the same due to the higher permeability connection with the SPR. Therefore, we did not spend excessive time trying to match modeled verses observed heads by changing K values. For this reason, we also believe that the model results are insensitive to the unlined pond model cell permeability. 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 proposed mine liner. We also do not believe the model results are sensitive to the existence of Lone Tree Creek because the shape of the mounding appears symmetrical west and east of the area of influence shown on Figure A9.

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 prediction (Figure A9) includes 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. CONCLUSIONS AND RECOMMENDATIONS We do not believe that the modeled+/- 1.0 foot rise on either side of the Goza pit will be noticeable to the homeowners listed in Table 1 because the amount is much less than natural fluctuations resulting from seasonal stage changes in the SPR and those caused by nearby ditch seepage. Recommendations We recommend that the applicant: 1. Confirm the locations of the SEO wells show on Figure Al and listed in Table 1; 2. Confirm there are no vulnerable structures located within the upgradient mounding area shown in Figure A10; 3. Continue to monitor existing monitoring wells; 4. In the future, make note of when the Canal 3 Ditches and Patterson Ditch start and stop diverting and evaluate seasonal water table fluctuations prior to and after pit construction to attempt to discern between changes in water levels caused by the pit verses seasonal changes caused by the South Platte River and nearby ditch recharge.

I I 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 has conducted this screening for federal and state listed threatened and endangered species and general wildlife for the approximately 67-acre survey area. The following provides key items identified as part of this report: 1. Four (4) primary land use class/vegetation cover types exist within the survey area. Habitat within the survey area is characterized as Western North American Cool Semi- Desert Ruderal Scrub and Grassland (82.9%); Great Plains Cottonwood-Willow Floodplain Forest (14.3%); Water (<1%); and Disturbed (1.8%; [NatureServe 2025]). Historic land uses associated with oil and gas activities and farming practices followed by vacancy have led to degradation of the native vegetation community. 2. Generally, there are features within the survey area and the surrounding properties that provide habitat for migratory birds, raptors, amphibians, and small to large-sized mammals. 3. Non-raptor birds: No active non-raptor bird nests were observed within the survey area. A nest survey should be completed no more than 7-10 days prior to vegetation removal to ensure that active nests are not disturbed and that no new nests have become established within the survey area. Non-eagle Raptors: No non-eagle raptor nests were observed within the survey area. Nest activity status can vary seasonally and from year-to-year. Future land use changes may require additional nest surveys (generally between February 1 and September 15 [CPW 2020]) to determine activity status within '/2 mile of the survey area to ensure compliance with CPW recommendations. Eagles: Two bald eagle nests are located within ' -mile of the survey area. One of the two bald eagles' nests is mapped within the survey area in the southeastern corner. During the site visit, one bald eagle was observed perching in mature trees within the riparian habitat. If impacts are expected to occur within 660 feet of Nest 04654B, then permitting through USFWS may be required (USFWS 2007); if impacts are expected to occur within ' -mile of either nest, CPW coordination is recommended (CPW 2023). 4. No federally listed T&E species were observed within the survey area during the site visit. The survey area is not within USFWS designated critical habitat of any federally listed species (USFWS 2025a). Preble's meadow jumping mouse is considered to have a "High" potential to occur; Ute ladies'-tresses are considered to have a "Low" potential to occur. Should any future land use changes occur, a ULT survey should be conducted to avoid adverse impacts. Due to the presence of suitable PMJM habitat, consultation with USFWS is recommended prior to disturbance to determine if PMJM trapping surveys are required within 300-feet of the mapped 100-year floodplains. Calven Goza galJ&T Consulting,Inc. Goza Pit DRMS 112 Permit Application 5. No state listed T&E species were observed within the survey area during the site visit. Burrowing owls are considered to have "High" potential to occur due to a prairie dog colony occupying a large portion of the survey area; the river otter has a "Low" potential to occur due to the riparian habitat adjacent to the South Platte River in the southeast portion of the survey area. Prior to any future land use changes, a burrowing owl survey should be conducted during the nesting season, March 15th through October 31st , to verify the presence/absence of burrowing owls. Any anticipated construction should take place outside of the burrowing owl nesting season. Potential impacts to river otters should be assessed prior to any disturbance of the riparian habitat within the survey area. 6. CPW-designated aquatic and terrestrial HPH overlaps the survey area. A 500-foot buffer from the ordinary high watermark of an aquatic native species conservation water (South Platte River) overlaps the southeastern portion of the survey area. Additionally, four terrestrial HPH's overlap the survey area: mule deer severe winter range; mule deer winter concentration area; and two bald eagle nest 1/2-mile buffers. CPW recommends no permitted or authorized human activities between December 1st and April 30th for mule deer severe winter range and mule deer winter concentration area. Recommendations for the aquatic native species conservation water includes no surface disturbance year-round within 500-feet of the ordinary high water mark of streams and coordination with a CPW aquatic biologist. Bald eagle nest recommendations include no surface disturbance year-round within '/4-mile of an active nest and a timing limitation which recommends no permitting or authorized human activities within 1/2-mile of an active nest from December 1st - July 31 st Attached is ERC's Screening Report for Federal and State Listed Threatened and Endangered Species.

The Western North American Cool Semi-Desert Ruderal Scrub and Grassland and Disturbed communities are dominated by weedy and invasive species including cheatgrass (Bromus tectorum), kochia (Bassia scoparia), Scotch cottonthistle (Onopordum acanthium), perennial pepperweed (Ledpidium latifolium), field bindweed (Convolvulus arvensis), and other ruderal grasses and forbs. These communities are associated with historically disturbed features of the Site, including former cropland, access roads, and oil and gas locations, that have since been abandoned or unused and colonized by rapidly growing species. These portions of the survey area provide food, cover, and open-space habitat for a variety of wildlife, including migratory birds, as well as small mammals, such as prairie dogs, rodents, skunks or rabbits. The Great Plains Cottonwood- Willow Floodplain Forest community, located in the southeast portion of the Site, provides high ecological value to wildlife. Two irrigation ditches, riparian habitat, and wetlands, are within the floodplain of the South Platte River and provide water sources and foraging areas for mammals and birds, as well as habitat for amphibians, and reptile species. This area has not been degraded as the surrounding vacant fields have, and shows signs of a healthy ecosystem, including dominant native vegetation, and frequent wildlife use. Wildlife resources within and adjacent to the Site were evaluated through desktop review and field reconnaissance,as documented in the Screening Report (Exhibit H, ERC 2025). Consistent with DRMS Rule 6.4.8(1)(a)-(c), wildlife resources identified in or near the Site include: • Migratory birds and non-eagle raptors utilizing available shrub and riparian vegetation • Bald eagle nesting territories within % mile of the Site • Prairie dog colonies providing potential habitat for burrowing owls • Mule deer severe winter range and winter concentration High Priority Habitat • Potential habitat for Preble's meadow jumping mouse within mapped floodplain areas No federally or state-listed threatened or endangered species were observed during field surveys; however, species-specific potential to occur is addressed in Exhibit H. 4.0 Project Impacts and Wildlife Protection Measures In accordance with DRMS Rule 6.4.8(1)(d)and Rule 6.3.1(8)(a),the proposed mining and reclamation plan will consider wildlife protection during construction, operation, and reclamation of the mine. The 1 ABC following measures are based on the findings and recommendations presented in the Wildlife Information Report (Exhibit H, ERC 2025). 4.1 Migratory Birds and Non-Eagle Raptors No non-raptor migratory bird nests were observed within the Site and no non-eagle raptor nests sites were observed. However, vegetation clearing activities conducted during the migratory bird nesting season (April 1' and August 31st) will be preceded by nest surveys to ensure active nests, if present, are not disturbed. 4.2 Eagles Eagle nests, including both bald eagles and golden eagles, are regulated by the U.S. Fish and Wildlife Service (USFWS) under the Bald and Golden Eagle Protection Act (BGEPA), with local review provided by CPW. However, USFWS, which has ultimate authority over species protected under both the MBTA and BGEPA. The USFWS recommends a 660-foot buffer around bald eagle nests to avoid and minimize disturbance to nesting eagles (USFWS 2007). CPW provides additional buffer and seasonal activity recommendations for bald and golden eagles, including no surface occupancy within a %-mile radius of active nests and no human encroachment activities within al/2-mile radius during the nesting season (CPW 2020, 2023). Two CPW-mapped active bald eagle nests (Nest 04654B and Nest 04654A) occur within%2 mile of the Site, with Nest 04654B mapped within the southeastern portion of the survey area. If project activities are proposed within 660 feet of Nest 04654B,consultation with USFWS will be initiated to determine whether a Bald Eagle Incidental Disturbance Take Permit is required under the BGEPA. 4.3 Burrowing Owl If disturbance to prairie dog colony areas is proposed during the burrowing owl nesting season (March 15—October 31), burrowing owl surveys and CPW coordination will be conducted as recommended to determine appropriate avoidance measures. If burrowing owls are identified nesting within active construction areas, avoidance buffers will be implemented and CPW will be consulted to determine appropriate protective measures, which may include temporary work restrictions. 4.4 Preble's Meadow Jumping Mouse If project activities are proposed within 300 feet of mapped 100-year floodplain areas containing potential suitable habitat, coordination with USFWS will be conducted to determine whether trapping surveys or consultation are required. 4.5 Mule Deer High Priority Habitat The Site occurs within CPW-designated mule deer severe winter range and winter concentration High Priority Habitat. Mining and reclamation scheduling will consider CPW timing recommendations for these habitats (December 1—April 30). If disturbance is proposed during this period, coordination with CPW will occur to identify appropriate avoidance or minimization measures. 5.0 Reclamation and Habitat Restoration Reclamation of disturbed areas will be conducted in accordance with the attached Reclamation Plan (Attachment A)and will include re-establishment of native vegetation communities.The final reclamation plan includes the creation of a slurry wall lined water storage reservoir. Side slopes will be constructed at 2 A ERC 3:1 and/or 4:1 gradient to allow wildlife that may enter the waterbody to safely exit, minimizing wildlife entrapment risk. 6.0 Summary This memo has been prepared in accordance with DRMS Rule 6.4.8, Exhibit H,to describe existing wildlife resources, seasonal use, the presence of sensitive species, and the anticipated effects of the proposed mining and reclamation activities. Based on available data, field observations, impacts to wildlife resources are not anticipated to result in adverse effects to wildlife species within or near the Site. The proposed project will implement avoidance, timing, surveys, and coordination measures described herein to minimize potential impacts to wildlife during construction, operation,and reclamation. 3 ERC REFERENCES CPW.

The approximately 67-acre property is located within the City of Greeley in Weld County,Colorado(herein referred to as survey area). The survey area is primarily undeveloped and comprised of vacant land, with the exception of an oil and gas well located along the eastern boundary.This report specifically documents and identifies potential federal and state-listed threatened and endangered (T&E) species and/or habitat that could exist on, or immediately surrounding, the survey area. In addition, this report also 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 Revised Statute Title 33, and Rule 6.4.8 of the Construction Materials Rules of the Colorado Mined Land Reclamation Board Exhibit H - Wildlife Information.This report provides documentation of findings related to federal and state listed T&E species and may serve as a resource for permitting or review by the U.S. Fish and Wildlife Service(USFWS)and/or CPW. 2.0 GENERAL SURVEY AREA DESCRIPTION State/County Colorado/Weld County Parcel#s 096115300021 and 096115300022 Nearest Town Greeley Property Size(ac) 67.6 Elevation (ft) 4,632 Street Address/ 0.4 mile west of the intersection of CR US-34 W Bus and E 24t"St Nearest Intersection Latitude, Longitude 40.397283° N, -104.65342°W (Center of survey area) Section/Township/ Section 15,Township 5 North, Range 65 West Range Watershed HUC City of Evans-South Platte River watershed -101900030606 The survey area can be accessed from the intersection of Highway 34 and General Directions East 24th Street by turning west on East 24th Street and,after 0.38 mile,taking from Nearest a left onto the dirt access road that runs along the northern boundary of the Intersection survey area. Survey Area Western North American Cool Semi-Desert Ruderal Scrub&Grassland;Great Vegetation Plains Cottonwood -Willow Floodplain Forest; Disturbed; Water 1 ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report Western North American Cool Semi-Desert Ruderal Scrub& Grassland This macro group contains disturbed grasslands and scrub found in semi- desert basins, piedmonts, and foothills throughout the western U.S. and Canada. Dominant graminoids include crested wheatgrass (Agropyron cristatum; which has been purposefully seeded for forage or to prevent soil erosion but has become naturalized) and cheatgrass (Bromus tectorum; an annual prolific seed-producer and highly invasive grass species). Numerous other non-native herbaceous species may be present to dominant.These are dry grasslands, forb-dominated meadows, or shrublands that occur in cool semi-arid climates. Stands occur on flat to moderately steep ground that can be large areas or narrow strips adjacent to roadsides or under powerlines and other disturbed areas. Soil is mostly mineral and well-drained. Soils may be compacted (NatureServe 2025). Vegetation Community Great Plains Cottonwood- Willow Floodplain Forest Description(s) This group is composed of woodlands and forests found along medium and small rivers in the western and central Great Plains from southern Canada to the Texas panhandle (NatureServe 2025). Plains cottonwood (Populus deltoides)is the most common tree and may be nearly the only species in the overstory in some stands. Other common trees are green ash (Fraxinus pennsylvanica), black willow (Salix nigra), and peachleaf willow (Salix amygdaloides). Disturbed These areas are defined by some form of human alteration or management, including barren grounds associated with oil and gas related activities,closely cropped vegetation such as lawns and landscaping,and urban materials such as buildings and pavement(NatureServe 2025).Tree canopy varies from 0 to 50% (e.g., open to shaded lawns and gardens). Notable features Patterson Ditch; unnamed irrigation ditch Refer to Figure 1 for a vicinity and U.S. Geological Survey (USGS) topographic map of the survey area and Figure 2 for field-verified vegetation communities.

ERC reviewed the following publicly available data resources: • Aerial imagery(Google Earth 2025) • USFWS Information for Planning and Consultation (IPaC) tool (USFWS 2025b) • Federal Emergency Management Agency(FEMA) National Flood Hazard Layer(NFHL; [FEMA • 2025]) • CPW High Priority Habitat(HPH)and Species Activity Mapping ([SAM]; CPW 2024; CPW 2025a) • NatureServe Explorer(NatureServe 2025) ERC completed a site visit on July 1, 2025,to identify, map,and evaluate natural vegetation communities, general wildlife use, and potential for T&E 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, foraging purposes, or as temporary shelter. Potential wildlife habitat includes the entire survey area. Historic and current oil and gas activities and land use practices have altered the native habitat for wildlife and the survey area is considered somewhat degraded, which can limit the overall quality of potential wildlife habitat. As discussed in Section 2.0,four habitat types were observed within the survey area and are characterized as Water (< 1%); Western North American Cool Semi-Desert Ruderal Scrub and Grassland (82.9%); Great Plains Cottonwood-Willow Floodplain Forest (14.3%); and Disturbed (1.8%; [NatureServe 2025]). The Western North American Cool Semi-Desert Ruderal Scrub and Grassland and Disturbed communities are dominated by weedy and invasive species including cheatgrass (Bromus tectorum), kochia (Bassia scoparia), Scotch cottonthistle (Onopordum acanthium), perennial pepperweed (Ledpidium latifolium), field bindweed (Convolvulus arvensis), and other ruderal grasses and forbs. These communities are associated with historically disturbed features of the site, including former cropland, access roads, and oil and gas locations, that have since been abandoned or unused and colonized by rapidly growing species. These portions of the survey area provide food, cover, and open-space habitat for a variety of wildlife, including migratory birds, as well as small mammals, such as prairie dogs, rodents, skunks or rabbits. The Great Plains Cottonwood- Willow Floodplain Forest community, located in the southeast portion of the survey area, provides high ecological value to wildlife. Two irrigation ditches, riparian habitat, and wetlands,are within the floodplain of the South Platte River and provide water sources and foraging areas for mammals and birds, as well as habitat for amphibians, and reptile species. This area has not been degraded as the surrounding vacant fields have, and shows signs of a healthy ecosystem, including dominant native vegetation, and frequent wildlife use. 6 ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report Other local wildlife species that may use this habitat within the survey area include bald eagles(Haliaeetus leucocephalus), mule deer (Odocoileus hemionus), red fox (Vulpes vulpes), coyote (Canis latrans), rabbit (Lepus spp.), fox squirrel (Sciurus niger), deer mouse (Peromyscus maniculatus), striped skunk (Mephitis mephitis), western meadowlark (Sturnella neglecta), hawks (Buteo spp.), frogs (Lithobates spp.), toads (Anaxyrus spp.), and garter snake (Thamnophis spp.).These types of species may utilize the survey area; however, have not all have been directly 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 large-sized mammals; however, the majority of habitat within the survey area is characterized primarily as weedy forblands, which is degraded from a wildlife perspective by historic land use practices. • The southeast portion of the survey area, comprised of Great Plains Cottonwood - Willow Floodplain Forest community, provides relatively high ecological value to wildlife, migratory birds, and raptors. The water sources and riparian area within the survey area provide wildlife species with cover and foraging areas. 5.0 MIGRATORY BIRD TREATY ACT Migratory birds are protected under the 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, nearly all bird species are protected under the MBTA, with the exception of non-native species, including the European starling (Sturnus vulgaris), house sparrow (Passer domesticus), Eurasian collared dove (Streptopelia decaocto), and rock pigeon (Columba livia; [USFWS 2020]). These species are not included in the list of protected birds under 50 Code of Federal Regulations § 10.13. Most of Colorado's commonly encountered bird species—whether nesting, migrating, or overwintering—fall under MBTA protections. Migratory birds exist within the survey area. The vegetation communities in the survey area provides potential nesting and foraging habitat for migratory birds. These migratory birds are protected under the MBTA, and the killing or possession of these birds(or their parts and nests) is prohibited under the MBTA. The following migratory birds were observed during the site visit and utilize the survey area for nesting, foraging, and migration corridors. Scientific Name Common Name Ardea herodias Great blue heron Corvus brachyrhynchos American crow Cyanocitta cristata Blue jay Haliaeetus leucocephalus Bald eagle Nycticorax nycticorax Black crowned night heron Pipilo maculatus Spotted towhee Riparia riparia Bank swallow Zenaida macroura Mourning dove 7 fol. ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report Non-Raptor Migratory Birds Non-raptor migratory birds likely utilize the survey area for foraging and nesting on a seasonal basis.These birds, their eggs, and active nests are protected under the MBTA, and the take or possession of these resources is prohibited. For 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 1st and August 315t. • No non-raptor migratory bird nests were observed within the survey area. Seasonal non-raptor MBTA bird nesting activity status can vary seasonally and from year to year. A nest survey should be conducted no more than 7-10 days prior to any future land use changes to ensure that any nests that have become established 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 by CPW. CPW has established raptor buffer guidelines, Recommended Buffer Zones and Seasonal Activity Restrictions for Colorado Raptors(CPW 2020). CPW considers a nest to be active when it is frequented or occupied by a raptor during the breeding season, or when it 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. CPW also maintains SAM data, an online database that lists the known occurrences, status, and recorded nest sites of raptors and other species within the state of Colorado (CPW 2025a). • No non-eagle raptors or nests were identified within the survey area during the site visit. There are trees within the survey area that provide suitable nesting substrates for raptors; however, due to leaf out conditions and public access limitation off-site, visibility of potential nests within suitable nesting trees was limited. Nest activity status can vary seasonally and from year-to-year. Therefore, future land use changes may require additional nest surveys to determine nest presence and activity status within 1/2-mile of the survey area to ensure compliance with CPW recommendations. Eagles Eagle nests are regulated by USFWS under the Bald and Golden Eagle Protection Act (BGEPA) with local review from CPW. USFWS,which has ultimate authority over species protected under both the MBTA and BGEPA, recommends a 660-foot buffer zone around bald eagle nests to avoid and minimize impacts to nesting bald eagles (USFWS 2007). Furthermore, CPW provides seasonal and buffer zone restriction recommendations for bald eagles and golden eagles(Aquila chrysaetos)in the Recommended Buffer Zones and Seasonal Activity Restrictions for Colorado Raptors (CPW 2020). For active bald eagle nests, CPW recommends "no surface occupancy"within X-mile radius, beyond that which historically occurred (CPW 2023). CPW also recommends "no human encroachment activities" within 1/2-mile radius of active nest sites from December 1st through July 31'(CPW 2023). For golden eagles,the same buffer zone restrictions 8 ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report as bald eagles apply, but seasonal restrictions are from December 15th through July 15th for this species (CPW 2023). • One (1) bald eagle was observed perched within the survey area during the site visit. Two CPW- mapped active bald eagle nests, Nest 04654E and Nest 04654A, are located within 1/2 mile of the survey area (CPW 2024). One of the nests is mapped within the southeast corner of the survey area (Nest 04654B). Due to leaf-out conditions and access limitations, direct visibility of either nest was limited. Coordination with CPW is recommended for both nests if ground-disturbing activities are proposed within the%mile protective buffer. If project activities are proposed within 660 feet of Nest 04654B, consultation with USFWS may be required and could result in the need for a Bald Eagle Incidental Disturbance Take Permit under the BGEPA. 6.0 SPECIES PROTECTED UNDER THE ENDANGERED SPECIES ACT OF 1973 The ESA of 1973 was enacted by the United States to conserve T&E species and the ecosystems that they depend on. Under the ESA administered by USFWS, species may be listed as either "endangered" or "threatened";both designations are protected by law.The USFWS has developed the IPaC tool,identifying T&E species, along with designated critical habitat, protected under the ESA that may occur within the boundary of a proposed project and/or may be affected by a proposed project (Appendix A; [USFWS 2025b]).Although the IPaC also identifies proposed or candidate species that may occur within the Survey Area, these species are not afforded protection under the ESA, and therefore, are not assessed in this report. The species list has identified potential for a total of 7 T&E species within the survey area. Common Name Scientific Name Status* Potential to Occur Ute Ladies'-tresses Sprianthes diluvialis FT Low Western Prairie Fringed Orchid Platanthera praeclara FT None Laterallus jamaicensis Eastern Black Rail FT None ssp.jamaicensis Preble's Meadow Jumping Zapus hudsonius preblei FT High Mouse Whooping Crane Grus americana FE None Water Depletion Species Pallid Sturgeon Scaphirhycchus albus FE None Piping Plover Charadrius melodus FT None *Status key:FT—Federally listed as threatened; FE—Federally listed as endangered Species Not Present The species with the "Potential to Occur" indicated as "None" 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. Water Depletion Species The USFWS under the ESA has determined that water depletions in the South Platte River Basin are considered an adverse effect to the species listed.The survey area is located within the South Platte River 9 ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report Basin. Any water related project conducted in the Platte River Basin that has a federal nexus, such as federal funding or a federal permit (i.e., Clean Water Act (CWA) Section 404 Permit), is subject to ESA Section 7 Consultation with the USFWS. The consultation is a mandate for water depletion projects that may affect threatened and endangered species that rely on the South Platte River. • The proposed Project is assumed to be industrial development that is supplied by an existing municipal water source, and therefore, would have no effect on the listed species, or their critical habitat. Species Potentially Within Range For the federally listed T&E species that have"Low"or"High" potential to occur,the survey area is located within the potential known range of these species and habitat is potentially present. 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 the designated critical habitat of any federally listed species (USFWS 2025a). UTE LADIES'-TRESSES(SPIRANTHES DILUVIALIS) The Ute ladies'-tresses([ULT];Spiranthes diluvialis)is a federally threatened plant species protected under the ESA. ULT occurs in seasonally moist soils and wet meadows near springs, lakes, or perennial streams and their associated floodplains. Populations have also been identified along irrigation canals, berms, irrigated meadows, excavated gravel pits, and other human modified wetlands (USFWS 2025c). ULT requires a habitat maintained in an early to mid- seral successional stage with an open canopy (USFWS 2025d). While certain invasive plants have the potential to directly compete with ULT, there are species that adapted to the same habitats as ULT and can commonly occur with ULT,these species include thistles (Cirsium spp.) and reed canary grass (Phalaris arundinacea), along with woody invasives such as Russian olives (Elaeagnus angustifolia; [USFWS 2025]). • The riparian floodplain associated with the South Platte River, along with the irrigation ditches, in the southeast portion of the survey area presents marginally suitable habitat for ULT. However, no Element Occurrence records of ULT are documented within the Greeley Quadrangle where the survey area is located (CNHP 2024). Therefore, ULT has a "Low" potential to occur, based on the presence of marginally suitable habitat and absence of documented observations surrounding the survey area.Should any future land use changes occur in the southeast portion of the survey area, a ULT survey should be completed to verify the presence/absence of ULT species and to avoid potential adverse impacts. PREBLE'S MEADOW JUMPING MOUSE (ZAPUS HUDSONIUS PREBLEI) On May 13, 1998, USFWS issued a final rule to list the Preble's meadow jumping mouse ([PMJM];Zapus hudsonius preblei) as a federally threatened species under the ESA. PMJM range extends from southwestern Wyoming through eastern Colorado. In Colorado, PMJM are associated with riparian ecosystems and can be found in areas of dense herbaceous and shrub cover. PMJM bears two to three litters per year, averaging five young per litter, in a grass-lined nest (CPW 2025c). USFWS provides 10 ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report recommendations and guidelines to determine the presence/absence of PMJM and PMJM habitat in Preble's Meadow Jumping Mouse Survey Guidelines Revised April 2004 (USFWS 2004). USFWS recommends that projects within 300 feet of the 100-year floodplains associated with rivers, creeks, and their tributaries be assessed as to the potential impacts on PMJM and their habitat (USFWS 2004). • According to USFWS survey data,three (3)trap sites are located east of the survey area along the South Platte River from 2001, 2003, and 2005 (USFWS 2018). The survey conducted in 2005, located approximately 0.47 miles east of the survey area, identified the presence of PMJM (USFWS 2018).The remaining two surveys conducted in 2001 and 2003 did not capture PMJM at their locations,approximately 1.3 miles and 0.06 mile east of the survey area,respectively(USFWS 2018). No USFWS designated critical habitat for PMJM occurs within the survey area (USFWS 2025a). The two irrigation ditches and their associated Great Plains Cottonwood Willow Floodplain Forest vegetation community along the floodplain of the South Platte River provides suitable habitat for PMJM. Dominant overstory consists of eastern cottonwood (Populus deltoides), green ash (Fraxinus pennsylvanica), peachleaf willow (Salix amygdaliodes), and crack willow (Salix x fragilis). The dominant understory consists of dense shrub and herbaceous coverage along the riparian area of Patterson Ditch and the unnamed ditch.The shrub community is dominated by Siberian elm (Ulmus pumila) and Russian olive (Elaeagnus angustifolia). Herbaceous vegetation is comprised of fowl mannagrass (Glyceria striata), reed canary grass (Phalaris arundinacea), and broadfruit bur-reed (Sparganium eurycarpum). The majority of the survey area is located within the 100-year floodplains associated with the South Platte River; FEMA NFHL shows Flood Zone AE extending into the northern and eastern portion of the survey area as well as a Regulatory Floodway in the southeastern corner of the survey area (FEMA 2025). • Based on the presence of suitable habitat and presence of positive trapping results located approximately 0.47 mile east of the survey area, PMJM has a "High" potential to occur. Should any future land use changes occur within 300 feet of the mapped floodplains, coordination with USFWS is recommended prior to disturbance to determine if PMJM trapping surveys are required within 300-feet of the mapped 100-year floodplain. 7.0 STATE THREATENED AND ENDANGERED SPECIES Species identified as state T&E are protected by the CPW under Colorado Statute Title 33-2-105. 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 (C.R.S. 2024). CPW also has identified State Species of Special Concern,which are species or subspecies of native wildlife that are currently vulnerable in their Colorado range and have the potential to become threatened or endangered. Species of Special Concern are not protected under State regulations but the 'take' of individuals and disturbance of their habitat is strongly discouraged. All state listed species were screened as potential inhabitants of the survey area based on general habitat requirements and CPW Species Profiles and CPW SAM data (CPW 2025a, 2025c). ERC evaluated the 11 ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report species listed by CPW as T&E that could potentially exist within the survey area. State listed species that also have a federal status (threatened, endangered, proposed, or candidate), were not duplicated below.

The survey area does not contain the specific habitat characteristics necessary to support the species listed above. These species and/or habitat are not present within the survey area. Therefore, any future land use changes will have no effect on the species, their habitats, or proposed or designated critical habitat. Species Potentially within Range For the state listed T&E species indicated as "Low" or "High" potential to occur suggests that the survey area is located within the potential known range of these species and habitat is potentially present. 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. BURROWING OWL(ATHENE CUNICULARIA) The burrowing owl (Athene cunicularia) is a small, diurnal owl, and is listed as a state threatened species in Colorado.This species breeds throughout the western U.S.; however, it rarely overwinters in Colorado (CPW 2021). Nesting occurs from late March through October (CPW 2021). Burrowing owls nest in 12 ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report mammal burrows and in both active and inactive prairie dog colonies, located in grasslands, mountain parks, well-drained steppes, deserts, prairies, and agricultural lands. Burrowing owls can usually be observed on low perches such as fence posts or dirt mounds. The clutch size can average six to twelve eggs and incubation lasts up to 30 days (CPW 2025c). The owlets usually run and forage at 4 weeks and fly at 6 weeks. Primary threats to this species are habitat loss due to intensive agriculture, as well as habitat degradation and fragmentation due to control of burrowing mammals. • No burrowing owl individuals were observed during the site visit. However,the Western North American Cool Semi-Desert Ruderal Scrub &Grassland vegetation community contains a large prairie dog colony that extends throughout the survey area (Figure 3).Therefore, burrowing owls have a "High" potential to occur, based on the presence of prairie dog colonies,which comprises suitable habitat for this species. • CPW recommends three burrowing owl surveys prior to any activities resulting in ground disturbance between March 15th and October 315T. If a nest is identified, CPW recommends no surface disturbance within 1/4 mile of the nest burrow. Prior to any future land use changes, presence/absence burrowing owl surveys are recommended within 1/4 mile of the survey area, in accordance with Recommended Survey Protocol and Actions to Protect Burrowing Owls (CPW 2021). RIVER OTTER (LONTRA CANADENSIS) The river otter (Lontra canadensis) is a State of Colorado threatened species. The primary habitat requirement for river otters is permanent water with abundant fish or crustacean prey and relatively high water quality(CPW 2025c). In Colorado, river otters often inhabit stream associated habitats(CPW 2025c). Lakes, reservoirs, beaver ponds, and floodplain wetlands also occur frequently within seasonal home ranges. Fish represent the vast majority of river otter diets range wide,and the presence of fish in suitable quantity typically constitutes an essential habitat component. Populations of this species were extirpated from Colorado in the 20th Century; however,since the 1970's, CPW has focused on reintroduction efforts (CPW 2025c). Based on the numbers of sightings over long periods of time post-release as well as on recent surveys, CPW reports that river otters have established breeding populations in several drainages, including the upper South Platte River. • CPW maps the overall river otter range approximately 3 miles downstream along the South Platte River; however, suitable riparian habitat along the segment of the South Platte River adjacent to the survey area is present (CPW 2025a). Potential suitable riparian habitat extends into the southeast portion of the survey area. Due to the survey area's proximity to the South Platte River that likely contains suitable habitat and the riparian areas within the survey area, there is "Low" potential for this species to occur. Therefore, prior to any future land use changes within the survey area, potential project impacts to river otters should be assessed and coordination with CPW is recommended. 13 ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report 8.0 HIGH PRIORITY HABITAT AREAS CPW has developed Recommendations to Avoid and Minimize Impacts to Wildlife from Land Use Development in Colorado which identifies HPH by species and provides general recommendations related to disturbances (CPW 2023). Although CPW has provided these recommendations for general land development, CPW is a recommending agency and does not have regulatory authority regarding HPH. • According to CPW data, a 500-foot buffer from the ordinary high watermark of an aquatic native species conservation water (South Platte River) overlaps the southeastern portion of the survey area (CPW 2024). Additionally, four terrestrial HPH's overlap the survey area: mule deer severe winter range; mule deer winter concentration area; and two bald eagle nest%z-mile buffers (CPW 2024; [Figure 4]). • Per CPW recommendations,the mule deer severe winter range and the winter concentration area HPH recommendations consist of timing limitations (CPW 2023). CPW recommends no permitted or authorized human activities between December 15t and April 30th (CPW 2023). Recommendations for the aquatic native species conservation water includes no surface disturbance year-round within 500-feet of the ordinary high water mark of streams and coordination with a CPW aquatic biologist(CPW 2023). Bald eagle nest recommendations include no surface disturbance year-round within %-mile of an active nest and a timing limitation which recommends no permitting or authorized human activities within %-mile of an active nest from December 1st-July 31st (CPW 2023). If activities are anticipated to occur within timing limitations or within specified distances to HPH,then consultation with CPW is recommended. 14 Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report rt "' f `e' 4• WI' LEGEND IN M. • P ❑ Sur;ey Are a • ... ;_ Prairie Dog Colontiy • `j - -�� -.j` Lei: .

Four(4) primary land use class/vegetation cover types exist within the survey area. Habitat within the survey area is characterized as Western North American Cool Semi-Desert Ruderal Scrub and Grassland (82.9%); Great Plains Cottonwood-Willow Floodplain Forest (14.3%); Water (<1%); and Disturbed (1.8%; [NatureServe 2025]). Historic land uses associated with oil and gas activities and farming practices followed by vacancy have led to degradation of the native vegetation community. 2. Generally, there are features within the survey area and the surrounding properties that provide habitat for migratory birds, raptors, amphibians, and small to large-sized mammals. 3. Non-raptor birds: No active non-raptor bird nests were observed within the survey area.A nest survey should be completed no more than 7-10 days prior to vegetation removal to ensure that active nests are not disturbed and that no new nests have become established within the survey area. Non-eagle Raptors: No non-eagle raptor nests were observed within the survey area. 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 % mile of the survey area to ensure compliance with CPW recommendations. Eagles:Two bald eagle nests are located within%-mile of the survey area. One of the two bald eagles' nests is mapped within the survey area in the southeastern corner. During the site visit,one bald eagle was observed perching in mature trees within the riparian habitat. If impacts are expected to occur within 660 feet of Nest 04654B, then permitting through USFWS may be required (USFWS 2007); if impacts are expected to occur within %2-mile of either nest, CPW coordination is recommended (CPW 2023). 4. No federally listed T&E species were observed within the survey area during the site visit.The survey area is not within USFWS designated critical habitat of any federally listed species (USFWS 2025a). Preble's meadow jumping mouse is considered to have a "High" potential to occur; Ute ladies'-tresses are considered to have a "Low" potential to occur. Should any future land use changes occur, a ULT survey should be conducted to avoid adverse impacts. Due to the presence of suitable PMJM habitat, consultation with USFWS is recommended prior to disturbance to determine if PMJM trapping surveys are required within 300-feet of the mapped 100-year floodplains. 5. No state listed T&E species were observed within the survey area during the site visit. Burrowing owls are considered to have"High" potential to occur due to a prairie dog colony occupying a large portion of the survey area; the river otter has a "Low" potential to occur due to the riparian habitat adjacent to the South Platte River in the southeast portion of the survey area. Prior to any future land use changes, a burrowing owl survey should be conducted during the nesting season, March 15th through October 31',to verify the presence/absence of burrowing owls. Any anticipated construction should take place outside of the burrowing owl nesting season. Potential impacts to river otters should be assessed prior to any disturbance of the riparian habitat within the survey area. 17 Altik ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report 6. CPW-designated aquatic and terrestrial HPH overlaps the survey area. A 500-foot buffer from the ordinary high watermark of an aquatic native species conservation water(South Platte River)overlaps the southeastern portion of the survey area. Additionally, four terrestrial HPH's overlap the survey area: mule deer severe winter range; mule deer winter concentration area; and two bald eagle nest -mile buffers. CPW recommends no permitted or authorized human activities between December 1st and April 30th for mule deer severe winter range and mule deer winter concentration area. Recommendations for the aquatic native species conservation water includes no surface disturbance year-round within 500-feet of the ordinary high water mark of streams and coordination with a CPW aquatic biologist. Bald eagle nest recommendations include no surface disturbance year-round within -mile of an active nest and a timing limitation which recommends no permitting or authorized human activities within 1/2-mile of an active nest from December 1st-July 315t This report has been prepared by: ECOLOGICAL RESOURCE CONSULTANTS, LLC 4/2/0— t/21/1 Morgan Colacone, Project Ecologist, PWS (303) 679-4820 x 112/mcolacone@erccolorado.net Tyler Worley, Sen logist, Certified Ecologist (303) 679-4820 x 105/tyler@erccolorado.net 18 ERC Goldman Goza Property Threatened & Endangered Species and General Wildlife Screening Report 10.0 REFERENCES C.R.S Colorado Revised Statutes. 2024.

New information based on updated surveys,changes in the abundance and distribution of species,changed habitat conditions,or other factors could change this list.Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed,listed,and candidate species and federally designated and proposed critical habitat (Colorado Ecological Services Field Office).Please note that under 50 CFR 402.12(e)of the regulations implementing section 7 of the ESA,the accuracy of this species list should be verified after 90 days.This verification can be completed formally or informally as desired.The Service recommends that verification be completed by visiting the IPaC website at regular intervals during project planning and implementation for updates to species lists and information.An updated list may be requested through the IPaC system by completing the same process used to receive the enclosed list. The purpose of the ESA is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved.Under sections 7(a)(1)and 7(a)(2)of the ESA and its implementing regulations(50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A Biological Assessment is required for construction projects(or other undertakings having similar physical impacts)that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act(42 U.S.C.4332(2)(c)).For projects other than major construction activities,the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat.Recommended contents of a Biological Assessment are described at 50 CFR 402.12. Project code: 2025-0115908 06/30/2025 19:28:16 UTC If a Federal agency determines,based on the Biological Assessment or biological evaluation,that listed species and/or designated critical habitat may be affected by the proposed project,the agency is required to consult with the Service pursuant to 50 CFR 402.In addition,the Service recommends that candidate species,proposed species and proposed critical habitat be addressed within the consultation.More information on the regulations and procedures for section 7 consultation,including the role of permit or license applicants,can be found in the"Endangered Species Consultation Handbook"at:https://www.fws.gov/sites/ default/files/documents/endangered-species-consultation-handbook.pdf. Projects and activities without a Federal nexus(e.g.,without Federal funding,permit,or authorization)should be evaluated for the potential to"take"listed wildlife.Take does not apply to listed plants and to designated critical habitat.The term"take"means to harass,harm,pursue,hunt,shoot,wound,kill,trap,capture,or collect,or to attempt to engage in any such conduct(ESA Section 3,Definitions).Harm in the definition of"take"in the ESA means an act which actually kills or injures wildlife.Such act may include significant habitat modification or degradation where it actually kills or injures wildlife by significantly impairing essential behavioral patterns,including breeding,feeding or sheltering(50 CFR 17.3). Gray Wolf: On November 8,2023,the Service promulgated an ESA section 10(j)(i.e.,experimental population)rule(10(j)rule) for gray wolf(Canis lupus)within the State of Colorado(88 FR 77014).For purposes of ESA section 7 consultation,we treat experimental populations as if they are proposed for listing,except on National Park Service and U.S.Fish and Wildlife Service lands,where they are treated as threatened.Evaluations for proposed species are completed under the regulations for conferencing(50 CFR 402.10).Conferencing for species that are proposed for Federal listing,or for proposed critical habitat,is only required if a proposed action is likely to jeopardize the continued existence of a species or will result in destruction or adverse modification of proposed critical habitat.If an action agency determines that their action would not jeopardize the continued existence of the species,and/or would not result in the destruction or adverse modification of critical habitat,and the Service concurs,the conferencing requirement is fulfilled. Suckley's Cuckoo Bumble Bee:On December 17,2024,Suckley's cuckoo bumble bee(Bombus suckleyi)(Suckley's)was proposed for listing as an endangered species(89 FR 102074).Suckley's is an obligate social parasite of social bumble bees in the genus Bombus.Suckley's cannot successfully reproduce without the availability of suitable host colonies.It is a semi- specialist parasite and confirmed to usurp nests of Western bumble bee(Bombus occiddentalis)and Nevada bumble bees (Bombus nevadensis)(Service 2024). Based on the best available information,no Suckley's have been observed in Colorado since 2014 despite ongoing surveys.The Species Status Assessment(SSA)shows observations since 2018 occur only in northern latitudes,primarily in Canada(Service 2024),but the species may persist in high quality upper elevation habitats in western States.While Suckley's is proposed for listing,there is no prohibition of"take"under Section 9 of the ESA;therefore,projects without a federal nexus,do not need to engage with the Service to exempt take under the ESA.However,we encourage including conservation measures benefiting pollinators and pollinator habitat into projects.Examples include retaining suitable foraging(diversity and abundance of native floral resources),nesting(suitable host colony above or below ground),and overwintering habitat(loose substrates such as leaf litter,duff,rotting logs);maintaining habitat for host bumble bees by avoiding impacts to abandoned underground holes(rodent burrows);and revegetation efforts that include native seed mixes to promote an abundance and diversity of native floral resources.Additionally,we recommend supporting and conducting general bumble bee and pollinator surveys. While the species is not currently known to occur in Colorado,we encourage proactive conservation actions to protect and conserve pollinators and pollinator habitat.Examples include retaining suitable foraging(diversity and abundance of native floral resources),nesting(suitable host colony above or below ground),and overwintering habitat(loose substrates such as leaf litter, duff,rotting logs);maintaining habitat for host bumble bees by avoiding impacts to abandoned underground holes(rodent 2 of 15 Project code: 2025-0115908 06/30/2025 19:28:16 UTC burrows);and revegetation efforts that include native seed mixes to promote an abundance and diversity of native floral resources.Additionally,we recommend supporting and conducting general bumble bee and pollinator surveys. Migratory Birds:In addition to responsibilities to protect threatened and endangered species under the Endangered Species Act(ESA),there are additional responsibilities under the Migratory Bird Treaty Act(MBTA)and the Bald and Golden Eagle Protection Act(BGEPA)to protect native birds from project-related impacts.Any activity resulting in take of migratory birds,including eagles,is prohibited unless otherwise permitted by the U.S.Fish and Wildlife Service(50 C.F.R.Sec.10.12 and 16 U.S.C.Sec.668(a)).For more information regarding these Acts,see https://www.fws.gov/program/migratory-bird-permit/ what-we-do. It is the responsibility of the project proponent to comply with these Acts by identifying potential impacts to migratory birds and eagles within applicable NEPA documents(when there is a federal nexus)or a Bird/Eagle Conservation Plan(when there is no federal nexus).Proponents should implement conservation measures to avoid or minimize the production of project-related stressors or minimize the exposure of birds and their resources to the project-related stressors.For more information on avian stressors and recommended conservation measures,see https://www.fws.gov/library/collections/threats-birds. In addition to MBTA and BGEPA,Executive Order 13186:Responsibilities of Federal Agencies to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities that might affect migratory birds,to minimize those effects and encourage conservation measures that will improve bird populations.Executive Order 13186 provides for the protection of both migratory birds and migratory bird habitat.For information regarding the implementation of Executive Order 13186,please visit https://www.fws.gov/partner/council-conservation-migratory-birds. We appreciate your concern for threatened and endangered species.The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act.Please include the Consultation Code in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

Measures for Proactively Minimizing Eagle Impacts For information on how to best avoid and minimize disturbance to nesting bald eagles, please review the National Bald Eagle Management Guidelines.You may employ the timing and activity-specific distance recommendations in this document when designing your project/ activity to avoid and minimize eagle impacts. For bald eagle information specific to Alaska, please refer to Bald Eagle Nesting and Sensitivity to Human Activity. The FWS does not currently have guidelines for avoiding and minimizing disturbance to nesting Golden Eagles. For site-specific recommendations regarding nesting Golden Eagles, please consult with the appropriate Regional Migratory Bird Office or Ecological Services Field Office. If disturbance or take of eagles cannot be avoided, an incidental take permit may be available to authorize any take that results from, but is not the purpose of, an otherwise lawful activity. For assistance making this determination for Bald Eagles, visit the Do I Need A Permit Tool. For assistance making this determination for golden eagles, please consult with the appropriate Regional Migratory Bird Office or Ecological Services Field Office. Ensure Your Eagle List is Accurate and Complete If your project area is in a poorly surveyed area in IPaC, your list may not be complete and you may need to rely on other resources to determine what species may be present(e.g. your local FWS field office, state surveys, your own surveys). Please review the Supplemental Information on Migratory Birds and Eagles, to help you properly interpret the report for your specified location, including determining if there is sufficient data to ensure your list is accurate.

The map unit descriptions, 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 and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils 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. Other minor components, however, have properties and behavioral 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 11 Custom Soil Resource Report 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. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one 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. 12 Custom Soil Resource Report Weld County, Colorado, Southern Part 3—Aquolls and Aquents, gravelly substratum Map Unit Setting National map unit symbol: 3627 Elevation: 4,000 to 7,200 feet Mean annual precipitation: 12 to 18 inches Mean annual air temperature: 45 to 55 degrees F Frost-free period: 80 to 155 days Farmland classification: Prime farmland if drained and either protected from flooding or not frequently flooded during the growing season Map Unit Composition Aquolls and similar soils: 55 percent Aquents, gravelly substratum, and similar soils: 30 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

The site has approximately 66.8 acres of upland habitat within the survey area consisting predominantly of ruderal Western North American Cool Semi-Desert Ruderal Scrub & Grassland. Topography across the survey area is generally flat with a lower elevation area in the southeast portion and a topographic high point of 4,630 feet in the southeast portion of the survey area. The vegetation community characterized within the survey area has been affected by historic and current disturbance associated with agriculture and oil and gas. Therefore, existing upland vegetation within the survey area represents somewhat degraded forms of these natural vegetation associations, dominated by non-native or invasive grass and forb species such as cheatgrass, Onopordum acanthium (Scotch cotton thistle), Rumex crispus (curly dock), and Bessie scoparia (kochia). Hydric soils, a dominance of hydrophytic vegetation, and/or wetland hydrology were not present in the upland habitats within the survey area. ERC's wetland delineation report is attached which includes descriptions of the general vegetation found on the site and wetlands found in the area. Note that none of the wetlands found on the site per the ERC report will be disturbed with the proposed mining for the site. The weed control plan for the site will be as follows and will be discussed and revised if needed by meeting with Tina Booton who is with Weld County's Weed Division: Mechanical and Chemical Control — Mowing will occur throughout the growing season in order to keep the plants from going to seed. Mowing will be terminated in late August followed by a herbicide treatment during late September through October — before a hard frost. Where controls cause vegetation to be removed, re-seeding will occur with native grass specified for the area per Weld County's recommendations and the re-seeding will occur the season after the weed control measures have been implemented. Chemical Control Only — A herbicide application will be applied from rosette to bud stage. This will be followed up with a fall application, if needed. The applicator (licensed if required by law for the type of herbicide) must read the label and use a herbicide labeled for the weeds present at the site. Noxious weed species to be managed are defined as those plant species currently identified by the Colorado State Department of Agriculture (CDA) as noxious under the Colorado Noxious Weed Act. The list is often updated and available at: https://www.colorado.gov/pacific/agconservation/noxious-weed-species Management efforts will be directed to those species identified under List A or List B by the CDA. List A species are required to be eradicated, while List B species will be controlled. Efforts to address List C species will follow guidelines of the Weld County Public Works Weed Management Division. Calven Goza 64' ICU Consulting,Inc.

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 (EPA)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, non-wetland aquatic resources can 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. (WOTUS) (i.e., such as streams or lakes) are further defined by the ordinary high-water mark(OHWM).The OHWM is characterized as"that line on the shore 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 soil,destruction of terrestrial vegetation,the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas" (USACE 2025a). These definitions are the basis of this delineation. ERC followed the methodology in the National Ordinary High Water Mark Field Delineation for Rivers and Streams: Final Version and recorded OHWM indicators at discrete locations using the Rapid Ordinary High Water Mark Field Identification Data Sheet (USACE 2025a). Additionally, ERC assessed wetland hydrology within the survey area with respect to rainfall normalcy using the Antecedent Precipitation Tool, Version 2.9.0 ([APT]; USACE 2025b). The APT is an automated software developed by USACE to standardize the methodology for evaluation normal precipitation conditions(USACE 2025b). Areas that do not meet any one of the wetland parameters (hydrophytic vegetation, hydric soils and/or wetland hydrology) or non-vegetated stream channel/open water (OHWM) were classified as a non- wetland (upland) and mapped as such. Any area determined to be potential WOTUS was delineated in the field pink flags identified with 'WETLAND BOUNDARY' printed on it and sequentially labeled alpha-numerically (i.e., Al, A2...). Wetland determination points and OHWM points were recorded using a hand-held Trimble Geo7X 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]; 4 ERC Goldman Goza Property Aquatic Resource Delineation Report Version 10.6)for spatial analysis and mapping.All aquatic resources delineated within the survey area are depicted on the Aquatic Resource Delineation Map in Appendix A. Wetland Determination data sheets are provided in Appendix B, OHWM sheets are in Appendix C,and the APT results are shown in Appendix D. 4.0 EXISTING CONDITIONS 4.1 LANDSCAPE SETTING Average Elevation 1 4,627 (Feet AMSL) Topography Generally flat Subregion (LRR) LRR G 67B, Western Great Plains Range and Irrigation Region Watershed HUC City of Evans-South Platte River watershed -101900030606 Nearest Waterbody Patterson Ditch Current Landuse Oil and gas facilities and vacant land Historic Landuse Agriculture and oil and gas facilities Dominant Vegetation Western North American Cool Semi-Desert Ruderal Scrub &Grassland; Communities Great Plains Cottonwood -Willow Floodplain Forest; Disturbed Reference (NatureServe 2025) General Vegetation The majority of the survey area is Western North American Cool Semi-Desert Description Ruderal Scrub & Grassland, dominated by invasive grasses and forbs as a result of current and past disturbances associated with agricultural practices and oil and gas activities. The southeastern portion of the survey area, within the South Platte River floodplain, is predominantly Great Plains Cottonwood - Willow Floodplain Forest vegetation community. This area is primarily upland, assumed to be infrequently and temporarily flooded, with riparian vegetation along the irrigation ditches. The disturbed areas include the oil and gas facility and the access roads across the survey area. Vegetation Community Western North American Cool Semi-Desert Ruderal Scrub& Grassland Description(s) This macrogroup contains disturbed grasslands and scrub found in semi- desert basins, piedmonts, and foothills throughout the western U.S. and Canada. Dominant graminoids include crested wheatgrass (Agropyron cristatum) (which has been purposefully seeded for forage or to prevent soil erosion but has become naturalized) and cheatgrass (Bromus tectorum) (an annual prolific seed-producer and highly invasive grass species). Numerous other non-native herbaceous species may be present to dominant.These are dry grasslands, forb-dominated meadows or shrublands that occur in cool semi-arid climates. Stands occur on flat to moderately steep ground that can be large areas or narrow strips adjacent to roadsides or under powerlines and other disturbed areas. Soils are mostly mineral and well-drained. Soils may be compacted. 5 Goldman Goza Property Aquatic Resource Delineation Report Great Plains Cottonwood- Willow Floodplain Forest This group is composed of woodlands and forests found along medium and small rivers in the western and central Great Plains from southern Canada to the Texas panhandle. Plains cottonwood (Populus deltoides) is the most common tree and may be nearly the only species in the overstory in some stands. Other common trees are green ash (Fraxinus pennsylvanica), black willow (Salix nigra), and peachleaf willow(Salix amygdaloides). Disturbed These areas are defined by some form of human alteration or management, including barren grounds associated with oil and gas related activities,closely cropped vegetation such as lawns and landscaping, and urban materials such as buildings and pavement. Tree canopy varies from 0 to 50% (e.g., open to shaded lawns and gardens). Notable Features Patterson Ditch; unnamed irrigation ditch Dates of Field Work July 1 and 16, 2025 Weather Partly cloudy, 55-90°F Typical The delineation was completed during the region's dry season.

A description of aquatic resource habitat types is provided below. The Aquatic Resource Delineation Map is provided in Appendix A. Wetland Determination data sheets are provided in Appendix B. Refer to Table 3 for a list of plant species identified within the survey area (USACE 2023). AQUATIC RESOURCE A (0.13 ACRE) (280 LINEAR FEET) Aquatic Resource A is an irrigation ditch in the southeastern portion of the survey area. Aquatic Resource A conveys irrigation flows from an upstream source during the growing season. Surface water was observed at the time of the delineation. Aquatic Resource A has a direct downstream continuous surface connection to Patterson Ditch (Aquatic Resource B) and the South Platte River, a traditional navigable waterway (TNW). Aquatic Resource A was delineated according to the OHWM, evident by the clear break in slope,transition from unvegetated to graminoids at the OHWM,and vegetation overhanging below the OHWM was matted down and bent downstream. Refer to form OHWM A-1 in Appendix C for indicators documented along Aquatic Resource A. Aquatic Resource A comprises a total of 0.13 acre (280 linear feet) of irrigation ditch within the survey area (Appendix A).

(depicted by yellow arrow).The OHWM is depicted by the blue line. AQUATIC RESOURCE B (0.69 ACRE) (909 LINEAR FEET) Aquatic Resource B, also known as Patterson Ditch, is an irrigation ditch with emergent riparian fringe wetlands (Rp1EM) habitat in the southeastern portion of the survey area. Aquatic Resource B conveys irrigation flow from Aquatic Resource A and the South Platte River via a headgate located downstream and outside of the survey area. Irrigation flows occur during the growing season. Surface water was observed at the time of the delineation. Aquatic Resource B has a direct downstream surface connection to the South Platte River, a TNW. Aquatic Resource B was delineated according to the OHWM and observed wetland criteria -the presence hydrology, hydrophytic vegetation and hydric soils. Overall, the vegetation community within Aquatic Resource B is dominated by species such as broadfruit bur-reed (Sparganium eurycarpum), plains cottonwood (Populus deltoides), and fowl mannagrass (Glyceria striata).The dominant species within the wetland fringe habitat consist primarily of hydrophytic species (OBL-FAC). Soils within Aquatic Resource B are mucky clay/loam in texture, exhibiting hydric soil indicators F1 (Loamy Mucky Mineral), F3(Depleted Matrix),and F6(Redox Dark Surface).At the time of the delineation, primary wetland hydrology indicators A2 (High Water Table between 0 and 3 inches below surface),A3 (Saturation at 0 inches), C2 (Dry-Season Water Table), and C7 (Thin Muck Surface) were observed. Secondary indicators B10 (Drainage Patterns), C9 (Saturation in Aerial Imagery), D2 (Geomorphic Position), and D5 (FAC-Neutral Test) were also observed. Aquatic Resource B meets the criteria for a wetland based on the presence of hydrophytic vegetation, hydric soils, and wetland hydrology. Aquatic Resource B comprises a total of 0.69 acre (909 linear feet) of irrigation ditch with emergent riparian fringe wetlands(Rp1EM) habitat within the survey area (Appendix A).

Step 2 Site conditions during field assessment First look for changes in channel shape,depositional and erosional features,and changes in vegetation and sediment type,size,density,and distribution.Make note of natural or man-made disturbances that would affect flow and channel form,such as bridges,riprap,landslides, rockfalls etc. The irrigation ditch is channelized with steep,incised banks that do not allow for riparian fringes. There appears to have been an outlet structure which allows for water to flow into Patterson Ditch(Aquatic Resource B);however,the structure appears dilapidated and to be no longer in use. Step 3 Check the boxes next to the indicators used to identify the location of the OHWM. OHWM is at a transition point,therefore some indicators that are used to determine location may be just below and above the OHWM.From the drop-down menu next to each indicator,select the appropriate location of the indicator by selecting either just below'b',at 'x',or just above'a'the OHWM.

Calven Goza J&T Consulting,Inc. Goza Pit DRMS 112 Permit Application EXHIBIT L Reclamation Cost A phased and cumulative bonding approach is proposed for the Goza 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.

Slope Stability Analysis Page ii I, INTRODUCTION Calven Goza proposes to mine the property located in the southwest 1/4 of Section 15, Township 5 North, Range 65 West of the 6th Principal Meridian, in the City of Greeley, Weld County, Colorado. The property is bounded by East 24th Street to the north, private property on the east, Colorado State Department of Highway and private properties to the south, and City of Greeley and private properties to the west. 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 effect on all man-made structures. Recommendations regarding acceptable setbacks from man-made structures have also been included. II. OVERVIEW The DRMS mining plan proposes that the property will be mined in a single cell. The cell will have a slurry wall liner constructed around it before it is mined, and will be reclaimed as a water storage reservoir. The mining will occur at 3H:1V to 4H:1V slopes. The reservoir will remain at the mined slopes, and will cover an estimated 24.35 surface acres when full at normal operating water level. The actual surface area will depend on the final configuration of the reservoir after mining/reclamation is complete. III. GEOTECHNICAL DATA Exploratory drilling and monitoring well installation were done on the site by CMT Technical Services. Logs of the borings/wells from this drilling that were 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 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. LICalven Goza-Goza Pit J&T Consulting, Inc.

DESIGN ANALYSIS AND CRITERIA The proposed mining slopes were analyzed using Clover Technologies Galena Slope Stability Analysis System, version 7.2. 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, twelve cases were identified as critical during the mining operation. Static and pseudo-static conditions were analyzed for 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 0.093 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, 0.7 x 0.093 = 0.065. The locations of the cases are shown on the case location map included in Appendix A. Case SS-1 — Sanitary sewer line west of the pit. The mining operation is adjacent to a sanitary sewer line on the west side of the pit. The proposed setback for mining is 72 feet from the sewer line. The mining depth was assumed to be 47 feet in this area based on bore log information. The mining/reclamation slope at this location is 3H:1V. Case SS-2 — Oil/gas line north of the pit. The mining operation is adjacent to an oil/gas line on the north side of the pit. The proposed setback for mining is 35 feet from the oil/gas line. The mining depth was assumed to be 42 feet in this area based on bore log information. The mining/reclamation slope at this location is 3H:1V. LICalven Goza-Goza Pit J&T Consulting, Inc. Slope Stability Analysis Page 2 Case SS-3 — Oil/gas line east of the pit. The mining operation is adjacent to an oil/gas line on the east side of the pit. The proposed setback for mining is 50 feet from the oil/gas line. The mining depth was assumed to be 18 feet in this area based on bore log information. The mining/reclamation slope at this location is 3H:1V. Case SS-4 — Oil/gas line east of the pit. The mining operation is adjacent to an oil/gas line on the east side of the pit. The proposed setback for mining is 40 feet from the oil/gas line. The mining depth was assumed to be 42 feet in this area based on bore log information. The mining/reclamation slope at this location is 4H:1V. Case SS-5 — Irrigation ditch south of the pit. The mining operation is adjacent to an irrigation ditch on the south side of the pit. The proposed setback for mining is 56 feet from the irrigation ditch. The mining depth was assumed to be 48 feet in this area based on bore log information. The mining/reclamation slope at this location is 3H:1V. 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/reclamation slopes. V. 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 (MLRB) for Factors of Safety for Slope Stability / Geotechnical Analyses. VI. 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 through 5 below. Calven Goza—Goza Pit ' J&T Consulting, Inc.

Slope Stability APa/ye'7 9 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. 1.1 Calven Goza-Goza Pit ' J&T Consulting, Inc.

Our office has reviewed the submitted materials,which were provided on behalf of the Colorado Division of Reclamation,Mining, and Safety(DRMS), and we offer the following comment that considers only the state action. Identification of Properties of Historical Significance Pursuant to CRS 24-80.1-104(3)water supply structures are exempt from the Colorado State Register Act. The proposed action will have no effect on any properties of historical significance,CRS 24-80.1-104(1). Please note that our comments should not be interpreted as concurrence under the National Historic Preservation Act or any other environmental law or regulation. Should the subject action change,we request that you contact our office for continued consultation under CRS 24-80.1. If human remains are discovered during ground disturbing activities,the requirements under CRS 24-80 part 13 apply and must be followed. In the event that there is federal agency involvement,please note that it is the responsibility of the federal agency to meet the requirements of Section 106 as set forth in 36 CFR Part 800 titled"Protection of Historic Properties." Section 106 consultation includes not only reasonable and good faith identification efforts of any historic properties located within the area of potential effects,but determining whether the undertaking will have an effect upon such properties. The State Historic Preservation Office,Native American tribes, representatives of local governments,and applicants for federal permits are entitled to consultative roles in this process.

TECHNICAL MEMORANDUM To: J. C.York J-T Consulting, Inc. 305 Denver Avenue, Suite D Fort Lupton, Colorado 80621 From: Meghan Dudley, M.A., SWCA Cultural Resources Project Manager Melanie Medeiros, M.A., RPA, SWCA Cultural Resources Principal Investigator Date: October 14, 2025 Re: Cultural Resource Support for the Goza Goldman Property Investigation Project in Weld County, Colorado I SWCA Project No. 99162 J-T Consulting, Inc. (J-T Consulting)contracted SWCA Environmental Consultants (SWCA)to conduct a cultural resource review and survey to support the proposed Goza Goldman Property Investigation Project(project). The project consists of investigating the Goldman property for a new gravel mine through borings on approximately 59.2 acres of agricultural land(Parcel Nos. 096115300021)(hereafter referred to as the project area) immediately east of Greeley, Colorado, on private land owned by Goza Goldman(Figures 1 and 2). Development of the proposed gravel mining pit investigation will be subject to permitting through both Weld County and the State of Colorado Division of Reclamation,Mining, and Safety. The purpose of the review and survey is to assess the project area for the presence of archaeologically and potentially sensitive cultural areas to assist J-T Consulting(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 survey, a summary of the results of the review and the survey, and recommendations as they relate to the project. PROJECT AREA AND LAND USE The project area is 2.1 miles east of Greeley,Weld County, Colorado, in the southwest quadrant of Section 15 of Township(T) 5 North(N),Range(R) 65 West(W), as depicted on the 1950 U.S. Geological Survey(USGS)Greeley, Colorado, 7.5-minute quadrangle(see Figures 1 and 2). The parcel is rectangularly shaped and is composed of formerly tilled land on a terrace of the South Platte River. The project area is bounded by East 24th Street to the north,residential developments to the west, agricultural fields and buildings to the east, and U.S. Highway 34 and the South Platte River to the south(Figures 3 and 4). The project parcel(Parcel No. 096115300021)is zoned as agricultural and owned by Calven T. Goza(Weld County 2025b).

The High Plains Level III ecoregion is a region of smooth to slightly irregular plains with a high percentage of cropland;natural vegetation in this Level III ecoregion is largely grama-buffalo grass (Chapman et al. 2006). Within the High Plains,the Flat to Rolling Plains Level IV ecoregion consists of a more level and less dissected landscape than the adjacent ecoregions and silty soils with a veneer of loess.Dryland farming— of primarily winter wheat and forage crops to a lesser extent—is widespread in this ecoregion,with some areas of irrigated cropland(Chapman et al. 2006). The project area is within the Platte River Basin, which is fed by the north-and west-flowing South Platte River 285 feet to the south of the project area(National Resource Conservation Service [NRCS] 2025). The underlying geology of the project area consists of modem alluvium, including Piney Creek Alluvium and younger deposits(Tweto 1979). Locally, one of highest terraces in the Platte River system is termed "T3"by geomorphologists because it is the third terrace above the modem 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-era agricultural activities. On the north side of the river north of Kersey,there is the modem floodplain alluvium and a strip of what is called the Hardin alluvium below the level of the T3,Kersey alluvium (Holliday 1987). The Hardin fill is characterized by bedded channel sands and finer-grained overbank alluvium and dates to less than 1,000 years BP(Holliday 1987; McFaul et al. 1994). Much of this landscape has been flattened by historic-era agricultural activities. Although soil series are mapped at too small a scale for fine-grained detail at archaeological sites, information from soil series can inform the nature of soil deposition and development; depth of those deposits; and,by extension,the potential for archaeological deposits. According to the NRCS (2025), there are two soil units mapped within the project area: an Ellicott-Ellicott sandy-skeletal complex, 0 to 3 percent slopes (an entisol), and aquolls and aquents gravelly substratum(mollisols) (Table 1 and Figure 5). The bulk of the project area(59.2%) is mapped as aquolls and aquents, a gravelly substratum with low potential for buried archaeological deposits.An Ellicott soil series,mapped for 21.9%of the project area, is formed from alluvium with poorly developed soil horizons and moderate depth(National Soil Survey 2007).As a result, it has low potential for buried deposits beneath the plow zone within the southeastern portion of the project area. 5 Cultural Resource Support for the Goza Goldman Property Investigation Project in Weld County, Colorado Table 1.

Mapped soil units within the project area. 7 Cultural Resource Support for the Goza Goldman Property Investigation Project in Weld County, Colorado METHODS In June 2025 and prior to fieldwork, SWCA requested a file search and literature review for the project area through the Colorado Office of Archaeology and Historic Preservation(OAHP)to identify records for all previously conducted cultural resource surveys and all previously identified cultural resources within the project area and within 1 mile of the project area;those results were received on July 18,2025. In addition, SWCA conducted background research,which included examination of historical topographic maps;historical and modern 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 or cultural resources. Following completion of this background research, on August 6,2025, SWCA archaeologists Meghan Dudley and Spencer Little completed a survey of the project area following OAHP guidelines(OAHP 2007)to identify cultural resources and potential impacts the project may have on those resources. Additionally, linear resources were recorded following Horn and Norton(2021). SWCA also excavated three shovel tests (ST1—ST3)to evaluate the subsurface depositional setting and assess the project area for the potential to contain buried cultural material. RESULTS File Search and Literature Review The results of the file search and literature review indicate that there have been 10 previous surveys conducted in the Public Land Survey System(PLSS) sections within 1 mile of the project area(Table 2). Only one of these surveys, WL.PA.NR2,overlaps with project area along its northern border. This survey was conducted for a wastewater outfall sewer project in 2002. The remaining nine surveys include a survey for the Weld County Municipal Airport, a fiber project,two road projects,two energy-related projects,one survey for historic-era barns, one NRCS survey, and one project that was undescribed.

All 22 resources are historic in age and include two historical markers, one canal and related segment, three ditches and related segments, one water outlet, two Centennial Farms,two agricultural complexes, one building, and one transmission line; three sites were also identified in the file search but no information was given for them. Eight of these resources are identified as eligible or supporting the eligibility of an entire linear resource: 5WL843 and 5WL843.16, Greeley No. 3 Canal and segment; four segments of the Lower Latham Ditch(5WL2948.10, 5WL2948.11, 5WL2948.12, and 5WL2948.14); and two Centennial Farms,the H.N. Bickling Farm(5WL2881) and Magnuson's Enzup Farm(5WL6723). Although H.N. Bickling Farm was returned in the file search data from the OAHP, it was misplotted in the system, and its actual location is northeast of Greeley beyond the file search area. Table 3.

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(Mehls and Mehls 2006;Weld County 2025a). Greeley, Colorado,was established by settlers in the Colorado Territory in 1869 as a utopian community built on the principles of faith, family, education,irrigation,temperance, agriculture, and home. Because agriculture was foundational to the new community,many ditches and canals were constructed to bring water from the Cache la Poudre and South Platte Rivers to cropland(Brooks 2013).As agriculture became more prevalent and additional people moved to the area,roads were established to connect local farmers to larger markets (Lynch 2015). The small outlying community of Garden City, southeast of Greeley and northwest of the project area,was established in 1938 as a home for liquor stores and bars after Greeley residents voted to continue prohibition after the national ban on alcohol was lifted(Garden City, Colorado 2025). Greeley quickly grew into a city and,by 1877,was the permanent county seat of Weld County. As Weld County's population grew, so did the roadways,infrastructure networks, and industry,which helped drive the local economy. Center pivot irrigation was invented after World War II and introduced into Colorado in the 1950s(Mader 2010). The agricultural infrastructure,new forms of transportation, and growing population of Greeley made the area around the project area ever changing in land use. In addition to cultivation, the oil and gas industry has been an integral activity in the region.Although many of the farms in the surrounding area were established by 1900,the oil and gas development started in the 1930s. Adding well pads to fields for the lease money was common at the time, as it is now, and provided another revenue stream for many of the family farms. This activity continued into the 1970s oil and gas boom and into the present. 10 Cultural Resource Support for the Goza Goldman Property Investigation Project in Weld County, Colorado General Land Office Land Patent Search A General Land Office(GLO)patent search was conducted through the BLM land patent database for Section 15 of T5N, R65W(Bureau of Land Management [BLM] 2025). One patent was issued for the project area to George T. Stone in 1896 under the Land Act of 1820(also referred to as the Sale-Cash Entry)(Document# 16471). Historical Map and Aerial Images Review SWCA also reviewed historical maps and historical and modern aerial imagery for features that may be present within the project area. Sources reviewed include 1865 GLO plat map for T5N,R65W(BLM 2025),USGS quadrangles(USGS 2025), and historical and modern aerial imagery(NETROnline 2025). During the late nineteenth century,the project area was undeveloped. The 1865 GLO plat for TSN,R65W depicts no potential cultural resources in the project area(BLM 2025). The only natural feature mapped is the South Platte River, south of the project area. The river's channel, instead of being east of the project area, is depicted as flowing roughly southwest-northeast south of the project area. A review of the historical topographic maps for the project area indicate that the project area continued to be largely undeveloped during the first half of the twentieth century. By the start of the twentieth century, the South Platte River channel was mapped in its current alignment(USGS 1902). Two unnamed ditches are depicted approaching the project area, one from the northwest and the other from the south. However, neither actually crosses the project area, and the land of and around the project area remains undeveloped. By the mid-twentieth century,the project area was still largely undeveloped. On the 1950 Greeley 1:24,000-scale quadrangle, a structure is depicted in the northwestern corner of the project area adjacent to East 24th Street,which is depicted in its modern alignment bounding the northern edge of the project area. Additionally,the quadrangle depicts northeast flowing Patterson Ditch crossing through the southeast corner of the project area. The 1954 Greeley 1:250,000-scale quadrangle is at such a small scale that no features are depicted within the project area, although a road collocated with East 24th Street is depicted bounding the project area to the north.No other cultural resources are depicted within the project area during the mid-twentieth century.

Greeley 1:250,000 1954(1951 No cultural resources are mapped in the project area at this time. aerial photograph, survey year 1954) 11 Cultural Resource Support for the Goza Goldman Property Investigation Project in Weld County, Colorado Available aerial imagery covering the project area dates between 1948 and 2021 (NETROnline 2025), with historical aerial photographs from 1948, 1949, 1957, and 1969. The earliest historical aerial photographs (i.e., 1948 and onward) show a structure in the northwest corner of the project area,with most of the remaining area covered by cultivated fields. Based on the larger farmstead visible to the west of the project area, it seems likely that this structure was an outbuilding or shed associated with that larger property outside the project area. An unnamed access road oriented north-northeast to south-southwest is shown transecting between plowed fields near the middle of the project area. Patterson Ditch is also visible transecting northeast-southwest through the southeast corner of the project area beginning in 1948 and on all subsequent aerial photographs. Modern aerial photographs between 1978 and 2021 depict a trend away from agriculture. The outbuilding visible in the 1948 imagery has been removed by 1978. The plowed fields are still visible through 1999, where a secondary north-south-oriented access road is visible,but,beginning in 2004,the land is no longer cultivated, and the access roads begin fading into natural prairie, disappearing by 2009. During the 2000s, substantial disturbance occurs in the project area, coinciding with oil and gas infrastructure construction at the site. In the south-central portion of the project area in 2005, several structures and a graded area are present;by the end of 2006,these structures are gone, and large debris piles are present in this portion of the project area. The Patterson Ditch continues to be visible in imagery through 2021. Imagery from 2019 and 2021 depicts the installation of a pipeline along the northern and eastern edges of the project area,with an aboveground pipeline access point visible north of Patterson Ditch. Overall,both the historical and modern aerial imagery show little development in the project area and surrounding landscape beyond agricultural development and the oil and gas development within the project area. SURVEY On August 6,2025, SWCA completed a survey of the project area to identify cultural resources and potential impacts the project may have on those resources.At the time of the August survey,the entire project area was a heavily disturbed, as a former agricultural field,with dense invasive disturbance-loving plants with very low visibility(less than 50%across majority of project area). One small portion(4.25 acres)of the southeastern portion of the project area across the Patterson Ditch was not surveyed due to the density of vegetation, including poison ivy, and the poor condition of the bridge that crossed the ditch (see Figures 1 and 2).Near the river, ground surface visibility was effectively 0%. No cultural material was observed on the ground surface during the survey. Three shovel tests (ST1—ST3)were placed in different environments of the project area to assess the deposition.Additionally,modern intrusions and modifications were clearly noted by the field crew. These included gas infrastructure as well as several push piles of modern construction debris in the southern portion of the project area, likely relating to construction on the modern gas pipeline infrastructure within the project area. This evidence of heavy disturbance is present across the project area, excluding wooded areas in the southeastern portion of the project area. SITE NARRATIVES REDACTED UNDER 54 UNITED STATES CODE 307103 AND 36 CODE OF FEDERAL REGULATIONS 800.11(C)(1). Shovel Test Results Because the project area is located on a secondary terrace on the north side of the South Platte River, SWCA personnel excavated three shovel tests (ST1—ST3)to evaluate the subsurface strata in different areas of the site and assess the potential for subsurface archaeological deposits (Table 5 and Figure 13). ST1 was placed in the southeast corner of the project area in the riparian environment along Patterson Ditch and the South Platte River. ST2 was placed just north of this riparian environment within the 12 Cultural Resource Support for the Goza Goldman Property Investigation Project in Weld County, Colorado disturbed field. ST3 was placed in the north-central portion of the project area within the northern extent of the disturbed field near the location of an old road visible on early aerial images. The three shovel tests revealed seven strata: • Stratum I is brown sandy loam with common rounded gravels present. • Stratum II is brown sandy loam with many rounded gravels to stones. • Stratum III is brown sandy clay loam with few rounded gravels. • Stratum IV is brown sandy loam with some dark gray mottling. • Stratum V is dark brown sandy clay with few gravels. • Stratum VI is dark brown sandy clay loam with increasing gravels. • Stratum VII is brown sandy loam with few subrounded gravels. Tests revealed similar matrices,particularly in the northern agricultural field;however,variations in the amount and size of pebble inclusions are representative of different alluvial deposition in these different areas. Shovel tests were terminated within gravel impasses or sterile B horizons of heavily compacted sediments. These observations from shovel tests are consistent with Ellicott soil units from recent alluvium and aquolls and Aquents gravelly substrata mapped in the project area(NRCS 2025). These tests confirm that the project area consists of relatively disturbed alluviums,which have low potential for buried archaeological materials. These shovel tests indicate shallow gravelly substratum soils,with no buried archaeological deposits. Although the strata revealed in the tests were all distinct,in terms of deposition they display evidence of active alluvial deposition disturbed by agricultural and industrial activity.No cultural materials were observed in the three excavated shovel tests.

Given the known historic-era agricultural tilling,modern construction disturbance evidenced by debris push piles in the southern portion of the project area, and the gas infrastructure present in the project area,this result was to be expected. Shovel testing confirmed that the project area retains minimal potential for intact buried deposits. 13 Cultural Resource Support for the Goza Goldman Property Investigation Project in Weld County, Colorado ly k kl I -- zdth st- -ST3, '... - _ . � . tr. 4 _ ibi 1r r U i r • 1 A. r OP 1 Ili - Aril , ,b ' 1116 ' r - V I. 41i Atk 'T I'- ' • 1Ighway,34_pyp S - - _High`wav 34�Byp' ` L J - _ -- - _, -' rlior , El Shovel Test Yield County.CO G LIsc, I5`Quadrangle: Project Area IS Nan 1983 UMW Zone 19N UnsUrvey€ci 40.5SJ4°N14E-6532•V4 N EIVM Area A iiri. .

Historic properties for which setting and feeling contribute to the overall eligibility of the resource were assessed for potential visual and cumulative effects due to the project. The landscape surrounding the project has been historically used and modified by agriculture since the 1860s. Settlement around what is now Greeley, Colorado,began in 1869. This settlement and agricultural development are most evident today in the various historic-era ditches and scattered farmsteads in the project area. This area expanded during the Depression era,with Garden City being established in the 1930s. Oil and gas development of Weld County expanded in the 1930s, and evidence of this industry can be seen across the landscape surrounding the project area. These systems of extraction, storage, and conveyance are continuously maintained and upgraded,with the infrastructure scattered across the fields surrounding the project area. In addition to these commercial developments, suburban residential development has been encroaching on the project area since the 1980s. Much of the residential agricultural and suburban properties have regular maintenance conducted on their properties, altering,upgrading, and destroying historic-era structures in the region. Though some of the farms do retain their original houses and sometimes their mature shade trees,many more farms have heavily modified or replaced the original buildings. These developments in the area's landscape history have altered the feeling of the original historic setting of Weld County. Additionally,gravel mines, consistent with this project, are relatively common development features on this landscape surrounding the South Platte River. In summary,the landscape surrounding the project area consists primarily of working farms to the south of the South Platte River and suburban residential development to the northwest. The oil and gas infrastructure are intertwined with agricultural use of the landscape,with the tanks at the associated well pads appearing similar to smaller silos and the pipe ducts on the pads appearing similar to irrigation pipes. Modern development in the form of new buildings on historic-era agricultural lands,newer small neighborhoods on the margins of former agricultural fields, and suburban residential and commercial properties are common, especially closer to the towns of Garden City and Greeley to the northwest. Because of the dense stands of trees and vegetation along the South Platte River,the viewshed from areas south of the river toward the project area was entirely obscured at the time of recording and it is expected to remain so even in the winter where the trees have lost their leaves. In addition, across East 24th Street, approximately 500 feet north of the project area,the landscape rises into a modified terrace shoulder, where Greeley Ditch Number 3 is routed. The area on this terrace contains gas infrastructure(not visible from the northern part of the project area), and the natural and modified features together obscure many line-of-sight from areas to the north of the project area, as well. As a result, although there are several historic-era resources in the surrounding landscape(both recorded and not),very few of them have direct viewshed from the project area. Similarly,view from the properties to the project area are also lacking. The file search results indicate that 22 previously recorded resources are within the PLSS sections within 1 mile of the project area. As described above, one of these was misplotted(5WL2881 [H.N. Bickling Farm]). Of the resources within this area, eight are eligible or support the eligibility of an entire linear resource. Six of these sites are ditches or ditch segments,representing the Latham and the Greeley Canal No. 3 ditches.Resources a the PLSS sections within a 1-mile buffer around the project area whose setting and feeling could be character-defining elements are described in Table 6. The historical map and aerial review indicate that numerous potential undocumented historic-era properties are present within the review area.All of these resources are of historic age.No other types of 15 Cultural Resource Support for the Goza Goldman Property Investigation Project in Weld County, Colorado resources beyond roads, farms, or irrigation infrastructure, such as ditches,were identified during the historical map and aerial review. Two of the previously recorded resources,Lower Latham Ditch (5WL2948)and Greeley Ditch No. 3 Canal(5WL843),have both recorded and unrecorded segments within the 1 mile of the project area.At least two other resources are linear roadways,East U.S. Highway 34 and East 24th Street. East 24th Street is the only resource visited by SWCA field staff that had good visibility to the project area. However,roads are generally assessed under Criterion A or Criterion C, and irrigation structures, such as ditches, are generally assessed under Criteria A,B,or C. Given this, setting and feeling are not character-defining elements of a county road or ditch; therefore,there will be no visual effect to the roads and ditches from the project. The project will consist of short-term, ground-disturbing activities, including subsurface borings. The surrounding landscape is characterized by modern intrusions that already impact the viewshed, and the river and terrace, to the south and north,respectively,both obscure the view into the project area. Existing pipelines and aboveground oil and gas infrastructure and transmission lines surrounding the project area are generally visible across the landscape. Therefore,the temporary visual impacts of subsurface borings will not result in a significant change to the potential eligibility or integrity of any resources in the vicinity of the project area.

Given the cumulative visual impacts already present in the area,including oil and gas infrastructure, agricultural infrastructure, and modern developments, SWCA recommends that the project will result in no effects to historic properties. 16 Cultural Resource Support for the Goza Goldman Property Investigation Project in Weld County, Colorado CONCLUSIONS AND RECOMMENDATIONS SWCA conducted a cultural resource inventory for the project in Weld County, Colorado. J-T Consulting is proposing ground-disturbing activities for investigating potential gravel mining,including subsurface boring. The project is on privately owned surface land. Overall,the project area encompasses 59.2 acres; 54.9 acres were surveyed for the undertaking, and 4.25 acres were excluded from the survey due to environmental hazards and lack of safe access. SWCA newly recorded two new cultural resources,both historic-era ditches(5WL2945.4 and 5WL10392). 5WL2945.4 is a newly recorded segment of the NRHP-eligible Patterson Ditch in the southeastern portion of the project area. Due to erosion and modem modifications, SWCA recommends that this segment does not support the eligibility of the entire linear resource. As the project would avoid this segment, SWCA recommends the project will result in no effect to historic properties;no further work is recommended. 5WL10392 is a newly recorded segment of an unrecorded,unnamed ditch. This ditch is recommended not eligible for the NRHP; no further work is recommended. Proximity(e.g.,visual)effects were considered within a 1-mile buffer around the project area on several previously recorded and potential,but unrecorded,historic properties,where setting and feeling are considered character-defining aspects of significance or on Native American sites of cultural and religious significance. The project is within a landscape already containing a modern built environment,where many of these modem intrusions are aboveground facilities more visible to the resources and closer than the current project. Additionally,the current project disturbance is ground-level, subsurface, and temporary in nature. SWCA recommends that this project will have no nonphysical effects to historic properties. Given the level of depositional disturbance caused by the modern agricultural use on this parcel and the disturbance associated with oil and gas infrastructure construction,which was confirmed by the survey and shovel tests,neither shallow nor native sediments that could retain precontact or early historic-era archaeological sites are likely to remain in the project area. The two historic-era resources recorded within the project area are both ditches, one which is a non-supporting segment of an eligible ditch and the other of which is not eligible for the NRHP. As a result,the project will result in no effect to historic properties, and no additional archaeological assessment is recommended in the project area. 17 Cultural Resource Support for the Goza Goldman Property Investigation Project in Weld County, Colorado REFERENCES CITED Ancestry.com. 2025a.
