REMAINDER RETAINED RE: Ogilvy River Farm Pit (Permit No. M-2024-006) ELECTRONICALLY IN TYLER. Adequacy Review #2 Dear Mr. Bowles, Ogilvy River Farm, LLC has received the Division's Adequacy Review #2 letter dated June 28, 2024. Below are the comments and the corresponding responses that we have provided to address the comments. Comments 6.4.4 Exhibit D - Mining Plan 1. Adequate as submitted. Response: Acknowledged. 2. The 1,146,176 cy of backfill material to reclaim the slopes from 2h:1 v to 4.5h:1 v will come from the overburden material. Will a stockpile be set aside containing this volume of material? Will the 2v:1 h slopes be contemporaneously backfilled as the mining highwall advances? Response: The backfill material will come from the overburden and clay that is at the site. Portions of the material will be stockpiled but the stock piled materials will be placed as mining occurs. The maximum linear footage of mining slope will be 1,500 feet and the reclamation will occur on the maximum linear footage prior to mining additional area. The volume of material for this length of slope is 340,350 CY. 6.4.7 Exhibit G - Water Information 5. Adequate as submitted. Response: Acknowledged.

The operator committed to monitoring all wells for inclusion of establishing baseline information in the June 1 adequacy review response. However, the text in Exhibit G was not updated to reflect this change and no additional data was submitted. Response: The revised Exhibit G is attached. The old attachment was included in the last adequacy review response. 8. The results also show that the water tested was not filtered as required by Reg. 41. Benchmark concentrations for metals listed in Reg. 41 are for dissolved metal concentrations, not total metals. Therefore, the results provided from November 17, 2023, are not suitable for comparison to the standards in Reg. 41 and will not contribute to the necessary 5 consecutive quarters of required testing to establish baseline. Response: The SGS samples were filtered for the dissolved metals testing. See updated information from SGS regarding the samples. 9. The Division suggests that to better establish baseline the Operator should sample all four monitoring wells for a minimum of 5 consecutive quarters and have the samples filtered as required before testing for the specified analytes from Tables 1-4 of Reg. 41. Response: The operators plan has been updated and all monitor wells will be included for establishing the baseline information. 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 SGS 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. The plan has been updated to include the process discussed in the response to Comment 10 below for collection of the samples. 10. Adequate as submitted. Response: Acknowledged. 11. Adequate as submitted. Response: Acknowledged. 12. The Operator should clarify if the samples are filtered in the lab by SGS Laboratories.

The operator's plan has been updated where the samples will be filtered in the field prior to delivery of the samples to SGS laboratories. 13. Adequate as submitted. Response: Acknowledged. 6.4.12 Exhibit L — Reclamation Costs 16. A cost estimate was not completed at this time because a significant amount of information needed to complete an estimate was requested in this adequacy review. A cost estimate will be completed when the information is received, and J&T Consulting will have an opportunity to review/comment on it. Response: Acknowledged. Ogilvy River Farm, LLC appreciates your consideration of this adequacy review response. Please feel free to contact me with any questions or comments. Sincerely, J.C. York, P.E. J&T Consulting, Inc.

Updated Groundwater Quality Testing Readings gm V1 305 Denver Avenue — Suite D • Fort Lupton CO 80621 • Ph: 303-857-6222 EXHIBIT G Water Information Introduction The Ogilvy River Farm Pit mining site is located in the Southeast 1/2 of the Southeast 1/4 of Section 5, Township 5 North, Range 64 West of the 6th Principal Meridian and the Northeast 1/4 of the Northeast 1/4 of Section 8, Township 5 North, Range 64 West of the 6th Principal Meridian, in Weld County, Colorado. The proposed mining site is located approximately 1,500 feet south of WCR 60'/2, is adjacent to WCR 53 on the side, and is adjacent to the South Platte River on the south side of the site. WCR 53 is immediately adjacent to the east side of the permit boundary and the South Platte River is immediately adjacent to the south side of the permit boundary. Access to the site will be located at the east side of the permit boundary off of WCR 53. The dominant land use surrounding the property is agricultural and industrial. 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 Ogilvy River Farm Pit site will last for approximately 5 years and 6 months. Once reclamation is complete, the water storage reservoir will be created with a total surface area being 37.63 acres. The depth to groundwater ranges from 3 to 24 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 68 to 85 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 4581 feet. To enable dry mining at the Ogilvy River Farm 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 6,500 feet long and 5 feet wide, or 0.75 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 Ogilvy River Farm 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 Ogilvy River Farm Pit mining site will include groundwater exposed in the dewatering trenches. El1 J&T Consulting, Inc. Ogilvy River Farm, LLC Ogilvy River Farm Pit DRMS 112 Permit Application The maximum exposed surface area at the site during mining is estimated at 0.75 acres. Ogilvy River Farm, LLC 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) (1967-2023) was used. The long-term average precipitation at the Ogilvy River Farm Pit mining site is estimated at 14.26 inches. Effective precipitation is calculated as 70% of the total precipitation. The net evaporation is the difference between gross annual evaporation and effective precipitation. The resulting net evaporation is 35.02 inches or 2.92 feet. The maximum annual evaporative loss from the 0.75 acres is 2.19 ac -ft. Operational Loss The average annual production from the Ogilvy River Farm 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 19.1 ac -ft. Dust control use is 10,000 gal/day, 6 days/week, 4 weeks/month for 10 months of the year. This equates to 7.4 ac -ft. Maximum annual operational loss is estimated to be 26.5 ac -ft. Consumptive Use The maximum annual consumptive use (operational loss + evaporation loss) at this site during the mining operation is estimated to be 28.69 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 Ogilvy River Farm Pit — Groundwater Evaluation by McGrane Engineering, LLC shows the permitted wells within 600 feet of the mining limits and permitted wells within the boundaries of the groundwater model/evaluation. The well information and locations were obtained from the Division of Water Resources online mapping well permit locator. This well and water rights information was cross checked with the State's CDSS. Between the sources, all permitted and decreed wells are included. 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 to 3 foot mounding area on the north and east side of the pit.

If the proposed use of groundwater at the Ogilvy River Farm Pit mining site results in material injury to surrounding wells, Ogilvy River Farm, LLC 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 Ogilvy River Farm 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. -� J&T Consulting, Inc. Ogilvy River Farm, LLC Ogilvy River Farm Pit DRMS 112 Permit Application Impacts to Groundwater/Hydrologic Balance Ogilvy River Farm, LLC will monitor the groundwater levels surrounding the site and provide groundwater recharge if necessary via perimeter ditches/ponds. Ogilvy River Farm, LLC 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, Ogilvy River Farm, LLC 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, Ogilvy River Farm, LLC will either implement a groundwater recharge ditch/pond near the well in order to raise the groundwater level in the vicinity of the well and hence return it's operation to acceptable standards, or will negotiate an agreement with that well owner to replace the well or provide replacement water via other means until the mining and reclamation activities are concluded but it is not anticipated that any groundwater levels will drop since the slurry wall will be installed prior to exposing groundwater. Groundwater wells that are not owned by Ogilvy River Farm, LLC 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, Ogilvy River Farm, LLC will either obtain a well waiver from the owner of the well, or provide an agreement with the well owner that Ogilvy River Farm, LLC 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 Ogilvy River Farm, LLC, or are monitoring wells therefore groundwater impacts to these wells do not need to be addressed. See the attached Piezometer Location Map, and Piezometer Data Summary, which show the locations of monitoring wells around the perimeter of the site that Ogilvy River Farm, LLC 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 Ogilvy River Farm, LLC will have four monitor wells sampled quarterly. The samples will be taken by a qualified consultant and then tested by SGS Laboratories for the analytes listed in Tables 1-4 of the "Basic Standards for Groundwater." El1 J&T Consulting, Inc. Ogilvy River Farm, LLC Ogilvy River Farm Pit DRMS 112 Permit Application 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. Ogilvy River Farm, LLC 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 SGS 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. 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. Ogilvy River Farm, LLC 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. The field sheets will be included in an appendix that demonstrates monitoring wells were purged and sampled according to the approved plan. El1 J&T Consulting, Inc.

REMAINDER RETAINED ELECTRONICALLY IN TYLER. Ogilvy River Farm, LLC has received the Division's Adequacy Review #1 letter dated April 26, 2024. Below are the comments and the corresponding responses that we have provided to address the comments. Comments 6.4.4 Exhibit D - Mining Plan 1. The chart on page D1 shows that 45.06 acres will be mined, 2.34 acres as roads the remaining 24.51 acres as disturbed. Can you describe how the 24.51 acres will be disturbed? The type of disturbance in this area needs to be described in clear detail because of its proximity to the South Platte River. Response: The chart on page D1 has been updated to show where disturbed acres are located. The disturbed areas will be adjacent to the mining slopes, and the area where the scale/scale house will be located adjacent to the access road. The majority of the area south of the existing road will not be disturbed adjacent to the South Platte River. 2. The mining plan shows that the mining faces will be mined to 2h:1 v. After mining is complete, the mining faces will be backfilled to 4.5h:1 v. Where is the backfill material coming from? What is the volume of the backfill material? Response: The backfill material will come from the overburden and clay that is at the site. Per the soil boring logs and volume calculations there is enough material on -site that can be used for the construction of the reclaimed slopes. The total volume of the backfill material is 1,146,176 cubic yards. }�hl 16RQeQ 1131 ai4 eze vw(CµjcKlvDpiIRulst�>) Uligitt4 2024-1726 RE: Ogilvy River Farm Pit, (Permit No. M-2024-006) Adequacy Review #1 June 21, 2024 -2- 6.4.6 Exhibit F - Reclamation Plan Map 3. The area south of the access road is shown as being topsoiled and seeded, although no mine related disturbance is proposed in this area. Please clarify why this area is being topsoiled and seeded. Response: The acreage has been updated to show where disturbed acres are located and the majority of the area south of the existing road will not be disturbed adjacent to the South Platte River. Exhibit Fl - Reclamation Plan Map and Exhibit F2 - Reclamation Plan Seeding Map have been updated to reflect the updated area to be topsoiled and seeded. The Final Land Use table in Exhibit E has also been updated to reflect this change. 4. The area south of the access road is shown as being completely covered with topsoil and seeded. Exhibit Cl shows that a large portion of the area contains buildings, paddocks, driveways, and easements. Are all these areas intended to be topsoiled also? Response: The acreage has been updated to show where disturbed acres are located and the majority of the area south of the existing road will not be disturbed. The area adjacent to the existing paddocks, driveway, and easements will not be topsoiled and seeded. Exhibit Fl - Reclamation Plan Map and Exhibit F2 - Reclamation Plan Seeding Map have been updated to reflect the updated area to be topsoiled and seeded. 6.4.7 Exhibit G - Water Information 5. The text on page G-1 states that the reservoir surface area will be 44.71 once reclamation is complete. The chart on page E-1 shows that the water surface area will be 37.63 for final land use. Please clarify the final surface water area of the reservoir. Response: The final surface water area of the reservoir will be 37.63 acres. The text on page G -1 has been updated to match the chart on page E-1. 6. The Piezometer Location Map was not included with the application. Please submit the Piezometer Location Map for review. Response: The piezometer location map has been included with the attachments to this letter. 7. The baseline data provided from SGS Laboratories test results are for MW -1 and MW - 3, not MW -1 and MW -4 as suggested in the Operators plan for establishing baseline. Please clarify as needed. Response: The operator's plan has been updated and all monitor wells will be included for establishing the baseline information. 8. The results also show that the water tested was not filtered as required by Reg. 41. Benchmark concentrations for metals listed in Reg. 41 are for dissolved metal concentrations, not total metals. Therefore, the results provided from November 17, VI 305 Denver Avenue — Suite D • Fort Lupton CO 80621 • Ph: 303-857-6222 RE: Ogilvy River Farm Pit, (Permit No. M-2024-006) Adequacy Review #1 June 21, 2024 -3- 2023, are not suitable for comparison to the standards in Reg. 41 and will not contribute to the necessary 5 consecutive quarters of required testing to establish baseline. Response: The SGS samples were filtered for the dissolved metals testing. See updated information from SGS regarding the samples. 9. The Division suggests that to better establish baseline the Operator should sample all four monitoring wells for a minimum of 5 consecutive quarters and have the samples filtered as required before testing for the specified analytes from Tables 1-4 of Reg. 41. Response: The operators plan has been updated and all monitor wells will be included for establishing the baseline information. 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 SGS 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. The plan has been updated to include the process discussed in the response to Comment 10 below for collection of the samples. 10. The Operator should be required to collect water levels of the monitoring wells monthly and collect analytical data quarterly before and after establishing the baseline. This plan should be maintained until baseline data is provided and approved by DRMS and any proposed modifications to this sampling plan are approved by DRMS Response: Ogilvy River Farm, LLC commits to collect water levels in the monitoring wells monthly and collecting analytical data quarterly for the water quality baseline information. This plan will be maintained to establish baseline data and submit to the DRMS for approval as well as during the operation of the mine. 11. The Operator should provide graphs to accompany a data table showing the depth of water versus time. Response: Ogilvy River Farm, LLC commits to providing graphs to accompany the data table showing the depth of groundwater versus time. 12. The Operator should clarify if the samples are filtered in the lab by SGS Laboratories. Response: The updated information is included from SGS clarifying the samples thus far were filtered for the dissolved metals testing. The operator's plan has been updated where the samples will be filtered in the field prior to delivery of the samples to SGS laboratories.

The Division suggests that the Operator uses the northwest monitoring well as a background water quality sampling location and the remaining three monitoring wells as points of compliance (PO0) for the long-term groundwater monitoring plan. The Division is open to reducing the number of POC wells for the operation over time if a subsequent request, submitted as a Technical Revision, and supported by the provided data is approved by the Division. Response: Ogilvy River Farm, LLC commits to using the northwest monitoring well as a background water quality sampling location after the baseline data is established. Ogilvy River Farm, LLC commits to using the remaining three monitoring wells as points of compliance for the long-term monitoring plan. 6.4.8 Exhibit H - Wildlife Information 14. The very western portion of the pit area is within 1/2 mile radius of a bald eagle's nest. The text states that no activity should occur in this area from December 1 through July 31. Activity proposed during this time requires prior consultation with CPW and/or USFWS. Will slurry wall construction and mine development take place outside of this timeframe to protect the bald eagle's nest?

A setback of 36 feet from the mining limit to the gravel road was demonstrated as meeting the MLRB requirements for Case SS -4. Can you clarify the distance from the mining limit to the fence line? Response: Yes, the distance from the mining limit to the fence line is 54 feet. 20. A setback of 59 feet from the mining limit to the gravel road was demonstrated as meeting the MLRB requirements for Case SS -2 during mining conditions. The reclaimed condition proposes a 45 -foot setback. How will a 45 -foot setback be achieved if a 59 -foot setback is required for mining? Response: The setback should be 59 feet for both the mining and reclamation conditions. The proposed setback shown in the report text for the reclaimed condition should have stated 59 feet to match the mining setback. The stability analysis used a setback of 59 feet at this location for both mining and reclamation conditions. The report has been updated.

The proposed mining site is located approximately 1,500 feet south of WCR 60%, is adjacent to WCR 53 on the side, and is adjacent to the South Platte River on the south side of the site. WCR 53 is immediately adjacent to the east side of the permit boundary and the South Platte River is immediately adjacent to the south side of the permit boundary. Access to the site will be located at the east side of the permit boundary off of WCR 53. The dominant land use surrounding the property is agricultural and industrial. The permit boundary will encompass approximately 71.91 acres which will all be affected acreage, and approximately 45.06 acres being mined. The remaining area will consist of access roads/scale/scale house, and disturbed/undisturbed land. The following table depicts the different affected acreage: Affected Acreage Mining Area (acres) Plan Mined Area 45.06 3.29 Access Roads / Scale / Scale House Disturbed Land Adjacent to Mining Slopes and 7.78 Scale/Scale House Undisturbed Land 15.78 71.91 TOTAL 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. Petroleum Development Corporation (PDC) is the leaseholder and operator of the existing abandoned wells. Discussions with PDC have indicated they would cut down the existing casings as mining occurs. We have also worked with McCarty Engineering, LLC to provide this service at other mining permit locations for other operators. If PDC does not want to perform this work then McCarty Engineering, LLC JET Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application would be contacted to do it. They are licensed and bonded to obtain approvals from the COGCC to do these types of re -plug services on abandoned oil and gas wells. Products Sand and gravel will be the primary product produced from the Ogilvy River Farm 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 Ogilvy River Farm Pit property contains a significant commercial deposit of sand and gravel. The depth of interbedded sandy clays at the surface range from 1 to 11 feet. The thickness of the aggregate material ranges from 46 to 81.5 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 (SFO) 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. iii' JET Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application 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 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 2H:1 V 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 90,000 cubic yards. The depth of the topsoil is approximately twelve inches over the majority of the mining area. The topsoil will be stripped and stockpiled prior to mining operations. The height of the topsoil stockpile will be approximately 15 feet. Mine Phasing Ogilvy River Farm, LLC anticipates mining and reclaiming the 55.78 -acre Ogilvy River Farm Pit progressing as shown on the Mining Plan Map. The overall time required to complete the mining and reclamation is estimated to be 5 years 6 months 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 could progress slower than anticipated and additional time may be required for mining and reclamation of the site. JET Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application 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. Dewateri ng 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. Ogilvy River Farm, LLC 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. iii' JET Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application EXHIBIT E Reclamation Plan Lined water storage reservoirs will be the final reclaimed use for the Ogilvy River Farm 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. Reclamation Plan (acres) Area Final Land Use Reservoir Water Surface 37.63 Access Roads 3.15 Reclaimed and Slopes Vegetated above Reservoir Land (Disturbed Water Surface) Land 15.35 Undisturbed Land 15.78 TOTAL 71.91 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 (SEC)) performance standards for permeability. All reservoir slopes will be reclaimed to at least 4.5H:1V final grade. Since reclamation will be concurrent with mining, most soil, overburden, and bedrock material excavated during mining will be used almost immediately. Scrapers and dozers and compactors will be used to shape the reclaimed slope material along the reservoir perimeters to achieve the final grade. Upon placing the backfill material, 95 percent compaction will be achieved to ensure adequate integrity of the liner, backfilled areas for haul/access roads and recharge pond areas that are not within the future water storage/reservoir footprint. Final reclamation by capping with topsoil and re - vegetating above the expected reservoir water level will follow grading operations as well as backfilled areas that will not be haul/access roads to minimize the amount of disturbance at any one time. Recommendations for monitoring of slope stability, including, conducting a visual inspection of the excavated slopes on a weekly basis for the duration of mining, conducting a visual inspection after a major precipitation event that has saturated the ground using the same procedures, contacting qualified personnel to evaluate and recommend remediation work to stabilize the area in the event a visual inspection detects signs of potential slope failure, and if no visible signs of slope failure are detected during mining, reducing visual inspections to once every six months after mining completion, or after every major precipitation event. JET Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application During reclamation activities, inlet and outlet facilities for the reservoir will be designed and installed once the operational criteria of the proposed reservoir have been identified by an end user. Reclamation Measures/Materials Handling Backfilling will be done to provide stabilized shorelines around the reservoir and to minimize erosion. The backfill material will consist of gravel, overburden, clay, and topsoil 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. Topsoiling Approximately the top twelve inches of soil on the property is classified as topsoil. This layer includes the root zone of grasses and crops, which will be stripped and stockpiled separately. 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 iii' JET Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application prior to using the mechanical seeder or broadcasting seed. Apply seed evenly in two 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 the DRMS for this climate zone (Dryland Quick Establishment, elevation less than 8,000 feet). Reservoir side slopes below the anticipated reservoir water level will not be seeded. The proposed seed mix is shown in the following table. Reclamation and Temporary Stockpile Seed Mix Seed Application Rate* Mix Species Scientific Name (#PLS/acre) Grasses Intermediate Wheatgrass Thinopyrum intermedium 2.50 Slender Wheatgrass Elymus trachycaulus, 2.00 Pubescent Wheatgrass Thinopyrum intermedium 3.00 Russian Wildrye Psathyrostachys juncea 3.00 Western Wheatgrass Pascoprum smithii 2.00 Sand Dropseed Sporobolus cryptandrus 0.25 *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- Weed s/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. 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 iii' JET Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application 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, Ogilvy River Farm, LLC 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 +/-1 to 3 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. Ogilvy River Farm, LLC 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 Ogilvy River Farm, LLC 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 5 years and 6 months. The following table shows the approximate time frame to finish each phase of mining assuming an average production rate of 650,000 tons per year: Acreage Time Frame to Complete and Reclaim Phase la and Phase 1 71.91 acres 5 years and 6 months The assumed annual production rate is 300,000 tons initially to 1,000,000 tons maximum for processed material leaving the mine each year. The size and area of reclamation varies but generally consists of the outside mining slope being reclaimed at a 4.5H:1V slope with the addition of clay, overburden, topsoil, and revegetation.

The proposed mining site is located approximately 1,500 feet south of WCR 60%, is adjacent to WCR 53 on the side, and is adjacent to the South Platte River on the south side of the site. WCR 53 is immediately adjacent to the east side of the permit boundary and the South Platte River is immediately adjacent to the south side of the permit boundary. Access to the site will be located at the east side of the permit boundary off of WCR 53. The dominant land use surrounding the property is agricultural and industrial. 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 Ogilvy River Farm Pit site will last for approximately 5 years and 6 months. Once reclamation is complete, the water storage reservoir will be created with a total surface area being 37.63 acres. The depth to groundwater ranges from 3 to 24 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 68 to 85 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 4581 feet. To enable dry mining at the Ogilvy River Farm 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 6,500 feet long and 5 feet wide, or 0.75 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 Ogilvy River Farm 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 Ogilvy River Farm Pit mining site will include groundwater exposed in the dewatering trenches. JET Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application The maximum exposed surface area at the site during mining is estimated at 0.75 acres. Ogilvy River Farm, LLC 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) (1967-2023) was used. The long-term average precipitation at the Ogilvy River Farm Pit mining site is estimated at 14.26 inches. Effective precipitation is calculated as 70% of the total precipitation. The net evaporation is the difference between gross annual evaporation and effective precipitation. The resulting net evaporation is 35.02 inches or 2.92 feet. The maximum annual evaporative loss from the 0.75 acres is 2.19 ac -ft. Operational Loss The average annual production from the Ogilvy River Farm 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 19.1 ac -ft. Dust control use is 10,000 gal/day, 6 days/week, 4 weeks/month for 10 months of the year. This equates to 7.4 ac -ft. Maximum annual operational loss is estimated to be 26.5 ac -ft. Consumptive Use The maximum annual consumptive use (operational loss + evaporation loss) at this site during the mining operation is estimated to be 28.69 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 Ogilvy River Farm Pit — Groundwater Evaluation by McGrane Engineering, LLC shows the permitted wells within 600 feet of the mining limits and permitted wells within the boundaries of the groundwater model/evaluation. The well information and locations were obtained from the Division of Water Resources online mapping well permit locator. This well and water rights information was cross checked with the State's CDSS. Between the sources, all permitted and decreed wells are included. 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 to 3 foot mounding area on the north and east side of the pit. iii' JET Consulting, Inc.

If the proposed use of groundwater at the Ogilvy River Farm Pit mining site results in material injury to surrounding wells, Ogilvy River Farm, LLC 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 Ogilvy River Farm 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. iii' JET Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application Impacts to Groundwater/Hydrologic Balance Ogilvy River Farm, LLC will monitor the groundwater levels surrounding the site and provide groundwater recharge if necessary via perimeter ditches/ponds. Ogilvy River Farm, LLC 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, Ogilvy River Farm, LLC 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, Ogilvy River Farm, LLC will either implement a groundwater recharge ditch/pond near the well in order to raise the groundwater level in the vicinity of the well and hence return it's operation to acceptable standards, or will negotiate an agreement with that well owner to replace the well or provide replacement water via other means until the mining and reclamation activities are concluded but it is not anticipated that any groundwater levels will drop since the slurry wall will be installed prior to exposing groundwater. Groundwater wells that are not owned by Ogilvy River Farm, LLC 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, Ogilvy River Farm, LLC will either obtain a well waiver from the owner of the well, or provide an agreement with the well owner that Ogilvy River Farm, LLC 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 Ogilvy River Farm, LLC, or are monitoring wells therefore groundwater impacts to these wells do not need to be addressed. See the attached Piezometer Location Map, and Piezometer Data Summary, which show the locations of monitoring wells around the perimeter of the site that Ogilvy River Farm, LLC 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 Ogilvy River Farm, LLC will have two monitor wells sampled quarterly. The upgradient monitor well that will be sampled is MW -1 and the downgradient monitor well that will be sampled is MW -4. The samples will be taken by a qualified consultant and then tested by SGS Laboratories for the analytes listed in Tables 1-4 of the "Basic Standards for Groundwater." iii' JET Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application 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. 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 annual report for the pit to the DRMS after approval of the permit application. Ogilvy River Farm, LLC 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. iii' JET Consulting, Inc.

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 98.2 -acre survey area. The following provides key items identified as part of this report: 1. Three primary land use class/vegetation cover types exist within the survey area. Habitat within the survey area is characterized as the Ruderal Smooth Brome Grassland (24%), Plains Cottonwood / Narrowleaf Willow Riparian Woodland (14%), and Row Crop Cultural Formation. Open water habitat within the South Platte River channel accounts for the remaining 8% of the total cover. Historic land use for agricultural practices has led to degradation of the native vegetation community. 2. Generally, there are features on the survey area and the surrounding area that provide general habitat for local songbirds, raptors, and small to mid -size mammals. However, habitat within the survey area is somewhat degraded and of lower ecological value from a wildlife perspective due to historic and current land use for agriculture, which has restricted overall growth and establishment of vegetation. The South Platte River and adjacent cottonwood riparian community provides suitable habitat for wildlife species and MBTA species. Although the South Platte River riparian corridor is not protected within the survey area, ERC recommends taking measures to avoid impacting these areas. 3. No non -raptor migratory bird nests were observed within the survey area. However, prior to vegetation removal a nest survey should be completed to ensure that no nests have become established within the survey area and active nests, if any, are not disturbed. 4. One active red-tailed hawk nest was identified approximately 200 feet south of the survey area. The survey area is subject to CPW red-tailed hawk nesting site recommended restricted use. The active nest site buffer creates a 1/3 -mile radius that extends across a majority of the southern end of the survey area in which no activity should occur from February 15 through July 15. Construction activities and surface occupancy may begin after the nest is no longer occupied. CPW recommends beginning any ongoing operation as close to the active nest site as practicable to allow raptors returning to the nest site to assess their level of tolerance to the continuing operations. Nest site trees may also be removed outside of breeding season while the nest is unoccupied and with the permission of the landowner. Activities proposed during the active breeding season while the nest is occupied will require consultation with CPW prior to beginning. 5. One bald eagle nest site was identified approximately 2,000 feet west of the survey area. The survey area is subject to CPW and USFWS bald eagle nesting site recommended restrictions. The active nest site creates a 1/2 -mile radius that extends across the far L' J&T Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application western portion of the survey area in which no activity should occur from December 1 through July 31; however, the survey area is outside of the 1/4 -mile surface occupancy restriction and features (pits, well, dwellings, etc.) are permitted to be constructed this area if they are placed there outside of the December 1 to July 31 timeframe. Activity proposed during this time frame will require prior consultation with CPW and possibly USFWS. 6. No federally listed threatened and endangered species and/or habitat protected under the ESA were identified within the survey area. The survey area is not within designated critical habitat of any federally listed species. The vegetation community and features within the survey area were investigated as potential habitat for federally listed species. Any future land use changes will result in No Take on any federal listed species, their habitats, or proposed or designated critical habitat. 7 No State listed threatened or endangered species and/or habitat protected by CPW under Colorado Statute Title 33 were identified within the survey area. The vegetation communities within the survey area were investigated as potential habitat for state listed species. Any future land use changes will have no effect on any state listed species, their habitats, or proposed or designated critical habitat. The Screening Report for Federal and State Listed Threatened and Endangered Species prepared by Ecological Resource Consultants, Inc. includes the following recommendations regarding migratory birds and raptor nest sites in the survey area: a. Based- upon literature review and an onsite assessment of the survey area, ERC has determined that some migratory birds likely utilize the survey area. These birds, their eggs, and active nests are protected under the MBTA and take or possession of these resources is prohibited. Active nests must become inactive prior to destruction of the nest without a USFWS permit. Five (5) inactive non -raptor migratory bird nests were observed within the survey area. The nesting season in Colorado for non -raptor migratory birds occurs between April 1 and August 31 (CPW 2020). Seasonal MBTA non -raptor bird nesting activity status can vary seasonally and from year to year, therefore nesting surveys should be conducted no more than 7-10 days prior any future land use changes to ensure active nests are not disturbed during nesting season. b. Raptor (non -eagle) migratory bird nest sites are further protected by CPW guidelines. CPW has established recommended buffer zones and seasonal activity restrictions for a variety of Colorado raptors. Three (3) inactive raptor nests were observed and no CPW mapped raptor nest protection zones are located within the survey area (CPW 2022a). Inactive raptor nest sites have no regulatory restriction and do not require further agency coordination; however nest activity status can vary seasonally and from year-to-year. Future land use changes may require additional nest surveys (generally between February 1 and September 15 (CPW 2020)) to determine activity status within 1/2 to 1/4 mile of the survey area to ensure compliance with CPW recommendations. c. Eagle nest sites are protected under Bald and Golden Eagle Act, further restricting destruction of any nest without a permit. No eagle nests sites were observed and no CPW nest sites eagle nests sites, communal roost sites, or winter roost sites are mapped on or within the vicinity of the survey area. Inactive eagle nest sites require further agency coordination even when nests are unoccupied as nest activity status can L' J&T Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application vary seasonally and from year-to-year. Future land use changes may require additional nest surveys (generally to be conducted between December 1 and July 31 (CPW 2020)) to determine activity status within 1/2 to'/4 mile of the survey area to ensure compliance with CPW recommendations. Regarding construction activities within the 1/2 -mile radius of a bald eagle's nesting site, consultation with CPW and/or USFWS will occur prior to slurry wall construction and mine development if those activities are contemplated to take place within the December 1st through July 31st timeframe. ERC would assist with consultation with CPW and/or USFWS. Regarding construction activities within the 1/3 -mile radius of a red-tailed hawk's nesting site, consultation with CPW will occur prior to slurry wall construction and mine development if those activities are contemplated to take place within the February 15th through July 15th timeframe. ERC would assist with consultation with CPW. Attached is ERC's Screening Report for Federal and State Listed Threatened and Endangered Species. L' J&T Consulting, Inc. Ogilvy River Farm, LL C Ogilvy River Farm Pit DRMS 112 Permit Application EXHIBIT L Reclamation Cost A phased and cumulative bonding approach is proposed for the Ogilvy River Farm 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.

The property is bounded by private property on the south, west, and north sides, and Weld County Road 53 on the east site. The South Platte River runs through the southern portion of the property. The proposed mining operation will extract gravel reserves from locations adjacent to man-made structures. The rules and regulations of the Division of Reclamation, Mining, and Safety (DRMS) require that any mining within a 200 -foot setback of a man-made structure show thorough engineering analysis that the proposed mining will not cause damage to the structure. The accepted method of demonstrating this is through a slope stability analysis. This report contains an overview of the methodology used in the analysis of the mining slopes and their estimated effect on all man-made structures. Recommendations regarding acceptable setbacks from man- made structures have also been included. OVERVIEW The DRMS mining plan proposes that the property will be mined in a single pit, and reclaimed as a water storage reservoir. The mining will occur at 2H:1 V slopes. The reservoir will be reclaimed by backfilling the mining slopes with overburden/clay soils at 4.5H:1 V slopes, and will cover an estimated 37.63 surface acres when full. The actual surface area will depend on the final configuration of the reservoir after reclamation is complete. GEOTECHNICAL DATA Exploratory borings and monitoring wells were done on the site by Cesare, Inc. / CMT Technical Services. Logs of the borings and monitoring wells used to estimate the soil types and thicknesses for this study are included in Appendix D. J&T Consulting, Inc. (JT) estimated soil strength parameters based on the information from the boring and monitor well logs and other stability analyses that have been performed on gravel mining operations along the Front Range. Table 1, on the following page, represents a summary of the soil strength parameters that were used in this stability analysis. id 1 J&T Consulting, Inc.

Galena was designed to analyze the slope stability of earth embankments subjected to several critical situations that may occur during the life of the embankment. For this project, six cases were identified as critical during the mining operation. Static and pseudo -static conditions were analyzed in each case. Pseudo -static peak acceleration factors (peak horizontal acceleration, or PHA) were taken from USGS information for the western United States. The 2% probability of exceedance in 50 years (the most conservative) was used. The USGS peak acceleration map is included in Appendix E. A peak acceleration factor of 0.09 x gravity was taken from this data. A conservative earthquake loading coefficient of 0.50 x PHA is often used for slope stability analyses (50% of PHA). We used an even more conservative approach and used 70% of the PHA for this area for our earthquake loading coefficient. Hence, 0.70 x 0.09 = 0.063. All mining side slopes will be 2H:1 V, and all reclaimed slopes will be 4.5H:1 V. The locations of the cases are shown on the case location map included in Appendix A. Case SS -1 — Gravel Road and Irrigation Ditch West of Pit. The mining operation is adjacent to an irrigation ditch and gravel road on the west side of the pit. The proposed setback for mining is 35 feet from the gravel road. The mining depth was assumed to be 79 feet in this area based on bore log information. Case SS -2 — Gravel Road and Irrigation Ditch North of Pit. The mining operation is adjacent to a gravel road and irrigation ditch on the north side of the pit. The proposed setback for mining is 59 feet from the gravel road. The mining depth was assumed to be 77 feet in this area based on bore log information. L1 J&T Consulting, Inc. Ogilvy River Farm, LLC. - Ogilvy River Farm Pit Slope Stability Analysis Page 2 Case SS -3 — Gravel Road, Fence, Buildings, Propane Tank, Irrigation Well, and Septic System South of Pit. The mining operation is adjacent to a gravel road, fence, buildings, propane tank, irrigation well, and septic system on the south side of the pit. The mining depth was assumed to be 74 feet in this area based on bore log information. 2 sub -cases were analyzed at this location: • Case SS -3A — Gravel Road o A proposed setback for mining of 39 feet from the gravel road. This case analyzed the factors of safety (static & pseudo static) for failure slices that affected the gravel road (the closest man-made structure). • Case SS -3B - Shop Building o A proposed setback for mining of 67 feet from the shop building. This case analyzed the factors of safety for failure slices that affected the shop building on the property to the south. This is the closest building south of the mining limit, and was considered as the maximum loading present south of the mining limit. The other buildings, propane tank, irrigation well, and septic system are the same distance or further away from the mining limit. The shop building was assumed to have dimensions of 90 feet long by 50 feet wide with a total maximum weight of 200,000 pounds when farm equipment is parked in the building, per information supplied by the land owner Roberta Smith. This information was used to determine a soil bearing pressure of 45 pounds per square -foot over the footprint of the building. This bearing pressure was included in the model as a distributed load over the floor of the building. • In both sub -cases wheel loads for a fully loaded Volvo A45G (45 -ton capacity) haul truck were placed on the gravel road. The maximum loaded wheel loads were determined to be at the rear axle, and were calculated to be 56,500 pounds per the manufacturer's information for the haul truck. The manufacturer's product information sheets showing the haul truck dimension and fully loaded weight information are included in Appendix F. Case SS -4 — Gravel Road and Fence West of Pit. The mining operation is adjacent to a gravel road and fence on the west side of the pit. The proposed setback for mining is 36 feet from the gravel road. The mining depth was assumed to be 66 feet in this area based on bore log information. Case SS -5 — Fence, Power Pole, Road, and Buildings East of Pit The mining operation is adjacent to a fence, power pole, road, and buildings on the east side of the pit. The proposed setback for mining is 39 feet from the fence/power pole. The mining depth was assumed to be 56 feet in this area based on bore log information. Case SS -6 — Access Road Easement, Gravel Road, Water Line, Telephone Line, Power Poles, Gas Line, Water Meter, and Mail Box South of Pit L1 J&T Consulting, Inc, Ogilvy River Farm, LLC. - Ogilvy River Farm Pit Slope Stability Analysis Page 3 The mining operation is adjacent to an access road easement, gravel road, water line, telephone line, power poles, gas line, water meter, and mail box, on the south side of the pit. The proposed setback for mining is 35 feet from the access road easement. The water meter and mail box are more than 100 feet away from the mining limit so the failure surfaces were calculated to the access road easement since it is closer to the mining limits, and as such lower factors of safety are present there. The other man-made structures are also further away from the mining limits and are shown on the cross-section located in Appendix B. The mining depth was assumed to be 51 feet in this area based on bore log information. The cross -sections located in Appendix B show the soil strata, soil properties, the phreatic surface associated with each case (blue line), the geometry used in the mining/reclamation, the locations of the man-made structures adjacent to the mining slopes, and the most critical failure surface calculated by the model (red line). 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. All cases were analyzed using mining condition geometry to determine the factor of safety for each case with the steeper mining slopes. Case SS -2, which is the deepest location that is adjacent to a critical structure (80 feet depth of reclamation slope), was analyzed to determine the minimum factor of safety for all reclaimed slopes. SLOPE STABILITY RESULTS When estimated soil strength parameters are used, the MLRB requires minimum safety factors of 1.50 for static condition analyses and 1.30 for pseudo -static (earthquake loading) condition analyses for embankments adjacent to critical structures. The calculated factors of safety are within the design criteria specified for this project and can be considered indicators of the mining slope performance under the various conditions. The results of the static condition and pseudo -static condition slope stability analyses are shown in Tables 2, 3, & 4 below. sI J&T Consulting, Inc.

Ogilvy River Farm, LLC. - Ogilvy River Farm Pit Slope Stability Analysis Page 7 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. id 1 J&T Consulting, Inc.
