REMAINDER RETAINED ELECTRONICALLY IN TYLER. Dear Mr. Bowles, Central Colorado Water Conservancy District (CCWCD) has received the Division's Adequacy Review #1 letter dated June 1, 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. Exhibits C2 and C3 show screening berms at various locations around the North and South Cells. What are the purposes of the berms, what are they constructed of, will they have erosion control structures in the areas where they are adjacent to the permit boundary, are they permanent, are they required by another agency, and will they have vegetation? Response: The purposes of the berms are to screen the proposed mining operation from adjacent properties. These were discussed with several of the neighbors at the first neighborhood meeting that was held in February 2024. The berms will be constructed of overburden and clay materials and topsoil will be added so the berms can be seeded with native grasses for the duration of the mining. The berms will be installed after slurry wall construction and prior to mining operations starting. There will be erosion control measures to control sediment transport per our approved grading plan permit with Weld County. 6.4.5 Exhibit E - Reclamation Plan 2. What is the intended use of the 12" inches of topsoil that was salvaged from the North and South Cells? These two cells combined are 72.3 aces which equates to an excess of -116,160 cy3 of topsoil. erlAbkiGgGUI.Ck) et: FL CITI � I5I Z�f 1J3i(L4 2024-2067 RE: Sweet Valley Pit, (Permit No. M-2024-015) Adequacy Review #1 July 30, 2024 -2- Response: The topsoil that is needed for the reclamation will be kept on site and used as reclamation occurs during the mining operations. The topsoil that is excess will be sold as a product during the mining operations. 6.4.7 Exhibit G - Water Information 3. 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. 4. 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 operator's 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 5 below for collection of the samples. 5. 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: CCWCD 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. 6. The Operator should provide graphs to accompany a data table showing the depth of water versus time. Response: CCWCD commits to providing graphs to accompany the data table showing the depth of groundwater versus time. 305 Denver Avenue — Suite D • Fort Lupton CO 80621 • Ph: 303-857-6222 RE: Sweet Valley Pit, (Permit No. M-2024-015) Adequacy Review #1 July 30, 2024 -3- 7. 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. 8. The Division suggests that the Operator uses the southeast monitoring well as a background water quality sampling location and the remaining three monitoring wells as points of compliance (POC) 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: CCWCD commits to using the southeast monitoring well as a background water quality sampling location after the baseline data is established. CCWCD commits to using the remaining three monitoring wells as points of compliance for the long-term monitoring plan. 6.4.12 Exhibit L — Reclamation Costs 9. 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. 6.4.19 Exhibit S — Permanent Man-made Structures 10. Please submit structure agreements with all landowners that have a structure within 200 feet of the permit boundary. Response: Structure agreements were sent out on July 29, 2024 and July 30, 2024 by e-mail and certified mail. The e -mails and certified mail receipts are attached as well as the letters that were sent out. CCWCD appreciates your consideration of this adequacy review response. 305 Denver Avenue — Suite D • Fort Lupton CO 80621 • Ph: 303-857-6222 RE: Sweet Valley Pit, (Permit No. M-2024-015) Adequacy Review #1 July 30, 2024 -4- Please feel free to contact me with any questions or comments.

The proposed mining site is located adjacent to WCR 42 on the north side, WCR 25.5 on the west side, and CO Hwy 60 on the east side. WCR 40 is approximately 2,630 feet to the south of the permit boundary. Access to the site will be located on the south side of the permit boundary and approximately 1,311 feet west of CO Hwy 60 and 1,285 feet east of WCR 25.5. The dominant land use surrounding the property is agricultural. 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 below exposed groundwater. Mining of the Sweet Valley Pit site will last for approximately 11 years and 8 months. Once reclamation is complete, the water storage reservoirs will be called the Sweet Valley Reservoir Complex with a total of two reservoirs. The north reservoir will have a water surface area of 32.42 acres and the south reservoir will have a water surface area of 40.10 acres. The depth to groundwater ranges from 13 to 18 feet seasonally within the permit boundary (measured in Existing MW, and MW -1 through MW -3, See the attached piezometer measurements table). The site will be mined down to a depth of 49 to 68 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 4749 feet on the south side of the property and an elevation of approximately 4739 feet on the north side. To enable dry mining at the Sweet Valley 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 north or south cell is completely mined, concurrently with reclamation since the mining slope is the same as the reclaimed slope. The maximum size of dewatering trench will be 0.75 acres of exposed surface area. The water will flow from the dewatering ditch to a small pond at the end of the dewatering ditch from which the water will be pumped where it will either be used for processing and dust control water or where it will be discharged to eventually reach the South Platte River. As mining progresses, the dewatering trenches will shift to account for additional groundwater being exposed. The gravel pit will have slurry wall liners for Phase 1 and Phase 2 constructed prior to exposing groundwater. Water Requirements Water use at the Sweet Valley 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 Sweet Valley Pit mining site will include groundwater exposed in the dewatering trenches. The maximum exposed surface area at the site during mining is estimated at 0.75 acres. CCWCD 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 Sweet Valley 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 Sweet Valley 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 the total associated consumptive use for water retained in the material mined 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 A-1 Well Permits in the Sweet Valley 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 Sweet Valley Pit — Groundwater Evaluation by McGrane Engineering, LLC that is attached that are within 600 feet of the mining limits and that were within the 1 to 3.5 feet mounding area on the north and south side of the pit.

If the proposed use of groundwater at the Sweet Valley Pit mining site results in material injury to surrounding wells, CCWCD 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 Sweet Valley 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 CCWCD will monitor the groundwater levels surrounding the site and provide groundwater mitigation via a groundwater drain or dewatering wells as described in the Groundwater Evaluation. The mitigation measures are provided with the Groundwater Evaluation. Design plans will be provided to the DRMS for the mitigation measures. CCWCD will discharge dewatering flows into existing adjacent irrigation laterals where possible to limit the disturbance to the surrounding land or discharge the dewatering flows via CCWCD's proposed pipeline that discharges directly to the South Platte River. A slurry wall liner is proposed around the Phase 1 and Phase 2 cells. To summarize the mitigation process, as the mining/dewatering occurs, CCWCD 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, CCWCD 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 and that mitigation measures to keep groundwater from mounding on the south side of the Phase 2 slurry wall will be in place such that baseline groundwater levels will be maintained to within plus or minus 2 feet. The north side of the Phase 1 slurry wall will be in a shadow area but all of the impacted wells are within the foot print of the approved permit boundaries of the Monarch Mine and the Section 20 Mine. Groundwater wells that are not owned by CCWCD 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, CCWCD will either obtain a well waiver from the owner of the well, or provide an agreement with the well owner that CCWCD 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 CCWCD 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 CCWCD 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, and stockpiles, which are not likely to affect groundwater quality. To establish pre -mining groundwater quality at the site CCWCD 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." 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. CCWCD commits to establishing points of compliance following five quarters of baseline monitoring. Monitor Well 3 located on the southeast 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 (POO), the POCs will be the Existing Monitor Well and Monitor Wells 1, and 2. 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. CCWCD 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.

The structure agreement is with Central Colorado Water Conservancy District (CCWCD) for the CR 25.5 and CR 42 ROW that are adjacent to CCWCD's property and are within 200 feet of the mine permit boundary. I have also included the maps showing the mining plan and the locations of the slope stability sections. Let me know if you have any questions and if you want to sign the agreement please send a scan of the signature page back to us. If not that is ok as well because we have performed a slope stability analysis that shows the mining slopes proposed are within the required factors of safety that the DRMS requires.

Prentice Avenue, Suite 100 Greenwood Village, CO 80111-2904 Re: Structure Agreement for Compensation for Damage to Structures within 200 feet of mining activities To Whom it May Concern: Central Colorado Water Conservancy District (CCWCD) is reaching out to you with a structure agreement because the proposed permit boundary for the Sweet Valley Pit is within 200 feet of your property or utility. The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the United States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. Please review the attached structure agreement; and if acceptable please sign and return.

The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the United States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. Please review the attached structure agreement; and if acceptable please sign and return.

CTW Properties, LLC 13434 County Road 42 P latteville, CO 80651-8715 Re: Structure Agreement for Compensation for Damage to Structures within 200 feet of mining activities To Whom it May Concern: Central Colorado Water Conservancy District (CCWCD) is reaching out to you with a structure agreement because the proposed permit boundary for the Sweet Valley Pit is within 200 feet of your property or utility. The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the U nited States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. P lease review the attached structure agreement; and if acceptable please sign and return.

Chad & Kelly Doolittle 19729 County Road 25.5 P latteville, CO 80651-8908 Re: Structure Agreement for Compensation for Damage to Structures within 200 feet of mining activities To Whom it May Concern: Central Colorado Water Conservancy District (CCWCD) is reaching out to you with a structure agreement because the proposed permit boundary for the Sweet Valley Pit is within 200 feet of your property or utility. The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the U nited States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. P lease review the attached structure agreement; and if acceptable please sign and return.

The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities.

The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the U nited States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. P lease review the attached structure agreement; and if acceptable please sign and return.

The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the United States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. ml sii 305 Denver Avenue — Suite D • Fort Lupton CO 80621 • Ph: 303-857-6222 Gerald & Teresa Moran and Sarah Drinkwine RE: Structure Agreement for Compensation for Damage to Structures within 200 feet of mining activities 2 Please review the attached structure agreement; and if acceptable please sign and return.

Box 37 Milliken, CO 80543-0037 Re: Structure Agreement for Compensation for Damage to Structures within 200 feet of mining activities To Whom it May Concern: Central Colorado Water Conservancy District (CCWCD) is reaching out to you with a structure agreement because the proposed permit boundary for the Sweet Valley Pit is within 200 feet of your property or utility. The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the U nited States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. P lease review the attached structure agreement; and if acceptable please sign and return.

Red Tierra Equities, LLC 8301 E. Prentice Avenue, Suite 100 Greenwood Village, CO 80111-2904 Re: Structure Agreement for Compensation for Damage to Structures within 200 feet of mining activities To Whom it May Concern: Central Colorado Water Conservancy District (CCWCD) is reaching out to you with a structure agreement because the proposed permit boundary for the Sweet Valley Pit is within 200 feet of your property or utility. The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the United States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. Please review the attached structure agreement; and if acceptable please sign and return.

Terry and Janice Weideman 13434 County Road 42 P latteville, CO 80651-8715 Re: Structure Agreement for Compensation for Damage to Structures within 200 feet of mining activities To Whom it May Concern: Central Colorado Water Conservancy District (CCWCD) is reaching out to you with a structure agreement because the proposed permit boundary for the Sweet Valley Pit is within 200 feet of your property or utility. The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the U nited States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. P lease review the attached structure agreement; and if acceptable please sign and return.

The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the United States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present.

Division Blvd. P latteville, CO 80651 Re: Structure Agreement for Compensation for Damage to Structures within 200 feet of mining activities To Whom it May Concern: Central Colorado Water Conservancy District (CCWCD) is reaching out to you with a structure agreement because the proposed permit boundary for the Sweet Valley Pit is within 200 feet of your property or utility. The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the U nited States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. P lease review the attached structure agreement; and if acceptable please sign and return.

The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the United States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. Please review the attached structure agreement; and if acceptable please sign and return.

The Colorado Mined Land Reclamation Act provides protection for your property, and specific protection for your structures located within 200 feet of the mining activities. Your property is adjacent to the mine property and within 200 feet of the mining activities. DRMS permit approval requires a notarized agreement between the applicant and owners of structures within 200 feet of the mining activities, providing compensation for any damage to the structure; or preparation of an engineering evaluation acceptable to the DRMS, demonstrating that such structure(s) shall not be damaged by the mining activities if an agreement cannot be reached. CCWCD has had an engineering evaluation performed to determine acceptable setbacks from their mining permit boundary and mining limit to structures adjacent to the mining. The proposed mining slopes and setbacks were analyzed using the Galena v7.1 computer program. 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. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 5,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the DRMS. The safety factors attained using the setbacks shown on the Mining Plan are greater than the required safety factors specified by the DRMS for an earth embankment during construction, and an earth embankment subjected to earthquake loading, based on the United States Geological Survey earthquake peak acceleration factors for the area. This evaluation indicated that damage to structures adjacent to the mining should not occur, even during earthquake conditions, which are unlikely to be present. Please review the attached structure agreement; and if acceptable please sign and return.
