(LRM) is applying to Weld County for Use by Special Review (USR) of their proposed Dunn Pit aggregate mine (Project), located in the northwest corner of Colorado Highway 257 (Hwy 257) and Weld County Road 481/2 (WCR 48 1/2) (Site). This letter contains the answers to the USR Procedural Guide — Planning Questionnaire. Included with this questionnaire are the other application components listed in the Planning Requirements Checklist. PLANNING QUESTIONNAIRE Question 1 Explain the proposed use and business name. Response 1 LRM proposes to mine alluvial materials from the Dunn Pit. LRM plans to: • Mine the aggregate materials "wet" (i.e., no dewatering) • Stockpile mined material adjacent to the active mining area • Load drained material onto 15 -ton tandem haul trucks • Truck aggregate material to the LRM's Johnstown Concrete -Batch Plant located at the corner of Colorado Hwy 402 and Weld County Road 13 Question 2 Explain the need for the proposed use. Colorado Office (Corporate) New Mexico Office 750 14th Street SW Loveland, Colorado 80537 970-484-7704 / 970-484-7789 (FAX) 1303 Pope Street Silver City, New Mexico 88061 575-538-5620 / 575-538-5625 (FAX) To: Weld County Department of Planning Services Date: May 17. 2022 Page 2 Response 2 LRM is proposing this Project because of the large demand, reduced supply, and increasing costs for sand and gravel within the Front Range community. The materials will be used in concrete production at the existing Johnstown Ready -Mix concrete plant for construction of housing, commercial projects, and other civil infrastructure. Question 3 Describe the current and previous use of the land. Response 3 LRM has owned the land since 1998 and currently leases the property out for pasture. Question 4 Describe the proximity of the proposed use to residences. Response 4 As shown on the USR Map, included with this submittal, and the attached Zoning Map (Figure 1), a number of residences are within the vicinity of the Site. One residential property is directly adjacent to the southwestern corner of the property. The Mad Russian residential development and golf course is located to the north of the Project Site, separated by the railroad easement. There are four residential lots on the south side of WCR 48 '/z, and one residential property east of Hwy 257 directly across from the Site. Question 5 Describe the surrounding land uses of the site and how the proposed use is compatible with them. Response 5 Properties immediately adjacent to the Project Site include the following: • One lot zoned residential (David Dunn) • Two lots zoned agricultural (Coulson Excavating Company Inc., Nelson Family LLC) Properties immediately south of WCR 48 '/z Right -of -Way (ROW) include the following: 20220517 PlanningQuestionnaire TT TELESTQ To: Weld County Department of Planning Services Date: May 17. 2022 Page 3 • Four lots zoned residential (Knaub, Stickler -Martin, Steffen, Vanwormer) • Two lots zoned agricultural (Terrell, Martin Del Campo) The Mad Russian Subdivision, north of the railway easement, include lots zoned commercial, residential, and vacant. The area's geology makes it ideal for sand and gravel mining, and a number of other sand and gravel mining operations exist in Weld County in the Big Thompson River corridor. LRM is committed to limiting disruption to surrounding lots and has prepared a traffic study, noise study, dust abatement plan, property values study, groundwater study, and groundwater sampling and analysis plan to assess potential impacts and to determine potential mitigation strategies for any identified impacts. Each of these studies is submitted with this USR application. The primary roads on the haul route from the Dunn Pit Site are WCR48 '/z, WCR17, WCR50, and WCR13. The Transportation Impact Study is included with the Development Review Submittal Requirements and predicts that none of the key intersections impacted by the Dunn Pit will warrant signalization in the short range (2026) and long range (2040) futures. However, several of the key intersections require auxiliary lanes, with existing traffic and before considering Dunn Pit haul route traffic, according to the criteria in the Weld County Engineering and Construction Criteria manual. Details on operations of specific intersections are included in the study. The Noise Evaluation Study predicts that sound levels will be below Weld County noise limits for both construction activity noise limits and residential noise limits and at the residential and commercial property lines. The Dust Abatement Plan identifies potential dust sources and measures to control dust emissions from those potential sources. Additionally, the Colorado Department of Public Health and Environment (CDPHE) requires the submission of an Air Pollution Emission Notice (APEN) for the operation of the construction and operation of the sand and gravel mine itself. In accordance with the standards set out by the CDPHE, the sand and gravel mine is classified as a minor facility and as a minor emission source. LRM has submitted the APEN for the Project and received a draft Construction Permit. The Property Values Study identifies a number of locations within Northern Colorado where residents choose to live in neighborhoods in close proximity to aggregate operations, either ongoing or reclaimed. Five neighborhoods were identified as examples of this situation. That many Larimer and Weld County residents choose to live adjacent to active aggregate operations is an indication that residential neighborhoods and aggregate operations can be compatible land uses. 20220517 PlanningQuestionnaire TT TELESTO To: Weld County Department of Planning Services Date: May 17. 2022 Page 4 The Groundwater Baseline Study predicts that the unlined mine cells will flatten gradients immediately adjacent to the pits and have a drawdown upgradient and a small mounding downgradient. No significant injury to any registered well owner is anticipated. The Groundwater Sampling and Analysis Plan, Appendix D of the Groundwater Baseline Study, summarizes LRM's plan to collect baseline water quality samples prior to mining activities. During active mining operations and reclamation, LRM will work with DRMS to develop a meaningful program to continue groundwater monitoring on a regular basis. Question 6 Describe the hours and days of operation (i.e. Monday thru Friday 8:00 a.m. to 5:00 p.m.). Response 6 LRM plans operation to be between the hours of 7:00 am and 5:00 pm Monday through Friday, which includes'/z hour at the beginning and end of the day for startup, maintenance, and shutdown. The Project hauling and mining hours are from 7:30 am to 4:30 pm Monday through Friday. Question 7 Describe the number of employees including full-time, part-time and contractors. If shift work is proposed, detail number of employees, schedule and duration of shifts. Response 7 LRM will employ two full time equipment operators and four truck drivers to work the Project. Question 8 Describe the maximum number of users, patrons, members, buyers or other visitors that the site will accommodate at any one time. Response 8 The aforementioned operators and truck drivers will access the Site daily (i.e., a total of 74 trip -ends daily). Engineering consultants will access the Site occasionally for permit monitoring purposes. Equipment maintenance personnel may access the Site as needed to work on equipment. 20220517 PlanningQuestionnaire TT TELESTQ To: Weld County Department of Planning Services Date: May 17. 2022 Page 5 Question 9 List the types and maximum numbers of animals to be on the site at any one time (for dairies, livestock confinement operations, kennels, etc.). Response 9 No animals will be kept on Site as part of the Project. The Site is currently used for grazing and areas of the Site may still be occupied by cattle before they are mined. Question 10 List the types and number of operating and processing equipment. Response 10 LRM will store an excavator, front-end loader, and small water truck on Site. Operator's personal or company vehicles, four -15 -ton haul trucks, and a service truck are the only other regular vehicles accessing the Site. Question 11 List the types, number and uses of the existing and proposed structures. Response 11 There are no existing structures on Site besides the oil and gas infrastructure currently installed. Oil and gas infrastructure includes a tank battery and associated well heads (4). The only permanent structure proposed for Project is the 60 -foot bridge over the Big Thompson River. Question 12 Describe the size of any stockpile, storage or waste areas. Response 12 The maximum topsoil stockpile size on Site will be 18,000 tons. The maximum aggregate stockpile on Site will be 5,000 tons. There will be no waste areas or waste storage. 20220517 PlanningQuestionnaire TT TELESTQ To: Weld County Department of Planning Services Date: May 17. 2022 Page 6 Question 13 Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. Response 13 The old fencing and cattle chutes will be hauled to the landfill. There will be no debris, junk, or other wastes produced from the Project. However, LRM regularly removes trash collected on its properties. Question 14 Include a timetable showing the periods of time required for the construction of the operation. Response 14 The Site will be mined in 5 -ac increments. Each increment will be reclaimed once mining is completed at that increment. The mine schedule is shown: ACTIVE MINING CELL INCREMENTAL MINED AREA (AC) TOTAL MINED AREA (AC) INCREMENTAL OVERBURDEN VOLUME (�3) 177'2 INCREMENTAL GRAVEL VOLUME (VD) INCREMENTAL GRAVEL WEIGHT CUMULATIVE GRAVEL WEIGHT (TONS) PRODUCTION YEARS AT END OF OF INCREMENT C1 0-5 5.0 157,020 251,232 251,232 1.26 C1 5-10 10.0 13,017 130,178 208,284 459,516 2.30 C1 10-15 15.0 11,811 145,593 232,949 692,465 3.46 C1 15-20 20.0 6,524 205,573 328,917 1,021,382 5.11 C1 20-25 25.0 4,153 206,724 330,759 1,352,141 6.76 C1 25-30 30.0 5,594 209,830 335,728 1,687,868 8.44 C1 30-35 35.0 7,956 224,537 359,259 2,047,127 10.24 C1/C3 35-40 40.0 2,991 174,586 279,338 2,326,465 11.63 C3 40-45 45.0 4,453 180,542 288,867 2,615,331 13.08 C3 45-50 50.0 4,640 186,147 297,835 2,913,166 14.57 C3 50-55 55.0 5,434 200,906 321,449 3,234,615 16.17 C3/C2 55-60 60.0 3,727 189,131 302,610 3,537,226 17.69 C2 60-65 65.0 313 181,780 290,849 3,828,074 19.14 C2 65-70 70.0 1,079 208,974 334,358 4,162,432 20.81 C3 70-75.9 75.9 7,594 239,323 382,916 4,545,348 22.73 20220517 PlanningQuestionnaire TT TELESTQ To: Weld County Department of Planning Services Date: May 17. 2022 Page 7 Question 15 Describe the proposed and existing lot surface type and the square footage of each type (i.e. asphalt, gravel, landscaping, dirt, grass, buildings). Response 15 The Site consists of approximately 114 acres of which —76 acres will be utilized for mining. The remaining —38 acres will consist of boundary offsets and the Big Thompson River corridor. The existing Site, with the exception of oil and gas access agreements and easements, is entirely pasture and used for grazing. Oil and gas wells are actively maintained via access agreements and easements (LRM does not own the oil and gas rights). Proposed Site improvements will include an additional access drive off WCR 48 1, a gravel Site access road extending from the drive, across the Big Thompson River to the northern side of the property, and a 60 -foot river bridge. The average access road length is 1,800 feet, from the access drive to mining cells, and 16 feet wide from shoulder to shoulder (28,800 sq. ft. of gravel). Question 16 How many parking spaces are proposed? How many handicap -accessible parking spaces are proposed? Response 16 No permanent parking spaces are proposed because the mining location will gradually progress across the Site. Mining equipment and employee parking will be located near the active mining location. Question 17 Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. Response 17 The Site is currently fenced with barbed wire. No additional fencing is proposed with the Project. Trees will be planted to provide some visual screening as shown on Figures 1 & 2 of the Landscaping Plan, included with this submittal. 20220517 PlanningQuestionnaire TT TELESTQ To: Weld County Department of Planning Services Date: May 17. 2022 Page 8 Question 18 Describe the existing and proposed landscaping for the site. Response 18 Existing vegetation within the project area consists largely of native grasses including Blue Gramma, Buffalo Grass, Needle and Thread grasses, and Western Wheat Grass. Minor noxious weeds (such as Thistle and Cheat Grass) are scattered or isolated on the property. Large Plains Cottonwood, Peach -Leaf Willow, Alder, and other short-lived trees such as Elm are located primarily along the Big Thompson River corridor. Figure 1 of the Landscaping Plan shows the areas to be reseeded in natural grasses as well as the shrubbery and trees to be planted. Some of the plantings will take place prior to mining, and some will occur as mining cells are reclaimed. The plantings along WCR 48 1, Hwy 257, and the railroad tracks will allow for visual screening along the perimeter of the property. Figure 2 of the Landscaping Plan provides a schematic of the final reclamation vegetation distribution, which also includes reclaimed ponds and wetland grasses. Question 19 Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity. Response 19 The Dunn Pit will be returned to wildlife habitat with groundwater sourced ponds as each of the three phases is completed. Mining and reclamation are planned in five -acre increments. Prior to the mining of each increment, topsoil, if present, will be stripped from the first mining increment and stockpiled adjacent to the active mining area. Topsoil stockpiles, ditches and grading may be used to direct stormwater into the mining cells. As soon as practicable after an area is mined, topsoil will be pushed into place to cover disturbed areas slopes. Slopes of 3H:1V or flatter will be established from 10 feet below the expected water line up to the existing ground surface. Slopes of 2H:1 V will be established from 10 feet below the expected water line down to bedrock. All disturbed areas above the water line will be seeded. Service roads and the bridge crossing will remain in place so that rangeland maintenance equipment may access the Site. Trees and shrubs adjacent to the mining cells will be planted in conjunction with corresponding slope reclamation. Based upon the mining and reclamation plans (see Exhibits C and F of the Dunn Pit Construction Materials Application, DRMS 112 20220517 PlanningQuestionnaire TT TELESTQ To: Weld County Department of Planning Services Date: May 17. 2022 Page 9 Reclamation Permit, included with this submittal), the maximum amount of reclamation to be completed at any one time is approximately one -to -two -acre average. Question 20 Describe the proposed fire protection measures. Response 20 Employees will receive a minimum of 4 hours of training in Mining Safety Health Administration (MSHA) Title 30 Code of Federal Regulations (30CFR), Part 46. Part 46 training will address the following subjects in addition to site -specific hazards. 1. Introduction to work environment, the method of mining and operation utilized. 2. Instruction on the recognition and avoidance of fire hazards, electrical hazards and other hazards present at the mine, such as traffic patterns and control, mobile equipment, and loose or unstable ground conditions. 3. A review of the emergency medical procedures, escape and emergency evacuation plans, instruction on the fire warning signals and firefighting procedures. 4. Instruction on health and safety aspects of the tasks to be assigned, including safe work procedures and mandatory health and safety standards pertinent to such tasks. 5. A review and description of the line of authority of supervisors and responsibilities of supervisors. 6. An introduction to rules and procedures for reporting hazards on site. 7. A review of first aid methods. MSHA will conduct a minimum of two site inspections a year to insure a safe and healthy workplace is provided. A regular safety and health inspection will include: 1. Inspection of active mine, shops, pump houses, electrical transmission facilities, flammable and combustible storage areas, all operating mobile and fixed equipment. 2. Inspection of active haulage and service roads, stockpiles, ponds, impoundments, pipelines, storage tanks, and offices. 3. Review of work practices and procedures. Fire extinguishers, and any water pipes, valves, outlets, hydrants, and hoses that are part of the mine's firefighting system shall meet all Mining Safety Health Administration (MSHA) regulations. This equipment will be inspected during MSHA and OSHA regular safety and health inspections. 20220517 PlanningQuestionnaire TT TELESTO To: Weld County Department of Planning Services Date: May 17. 2022 Page 10 Question 21 Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. Response 21 The Comprehensive Plan, as adopted, establishes policy guidelines for land use decisions and the foundation of all land use and development regulations. The Guiding Principles, Goals, and Objectives in the Comprehensive Plan Chapter 22 were used to develop this land use application along with the applicable Goals and Objectives in Chapters 8, 19, 21, 23, 24, and 27. The Weld County Transportation Plan provided in Chapter 8 was considered as part of the Traffic Impact Study provided with this application. Chapter 19, Coordinated Planning Agreements, was reviewed for Coordinated Planning Agreements between the County and adjacent municipalities. Articles VIII and XXI require that the County shall refer all proposals for development within the Three (3) Mile Area to the Towns of Milliken and Johnstown for review and recommendation. Chapter 21 was reviewed for regulations concerning activities of state interest; unless otherwise determined by the County, this project does not fall under 1041 Regulations. Chapter 23 was reviewed for compliance with the Zoning Ordinance and is addressed in Question 22 that follows. Chapter 24 concerns the Subdivision Ordinance and unless otherwise determined by Weld County Planning does not apply to this project. Chapter 27 provides specific requirements for Planned Unit Development and does not apply to this project. This Project complies with the Weld County Guiding Principles (Sec. 22-2-10) as follows: • Respecting Our Agricultural Heritage: The Project will not infringe on agricultural production in the area. The Site is currently used for grazing. • Respecting Private Property Rights: LRM has a right to mine the aggregate on its property for use in the community. The mining operations have taken into consideration the rights of all neighboring properties with the intent of minimizing impacts. 20220517 PlanningQuestionnaire TT TELESTO To: Weld County Department of Planning Services Date: May 17. 2022 Page 11 • Promoting Economic Growth and Stability: Allowing local aggregate mining will help provide construction material that is in high demand, without increased costs of transportation. • Protecting Health, Safety, and General Welfare: LRM is studying groundwater impacts, water quality impacts, changes to the flood zone, noise impacts, and air quality impacts associated with the project in order to implement the proper best management practices for minimizing effects to community. Additionally, LRM is going beyond the requirements of DRMS, CDPHE, and other regulatory agencies by taking into consideration concerns from the community through actions such as voluntary community meetings. The Goals of the Comprehensive Plan are divided into categories of Land Use, Economic Development, Environmental, and Natural Resource. Each Goal is included and addressed as follows. Sec. 22-2-30 Land use goals and objectives A. Commit to the economic future of agriculture. 1. As shown on the USR Map, included with this submittal, this Project does not inhibit agriculture production or operations on any of the adjacent properties. Access to neighboring agriculture properties is not impacted. There are no irrigation ditches, tailwater ditches or irrigation easements that cross to neighboring properties. 2. No neighboring irrigation or water rights are impacted as shown on the Vicinity Map and documented in the Stormwater Detention Exemption Drainage Narrative, submitted with the Development Review requirements. 3. This property has been historically used for limited grazing pasture. The vegetation within the Site is subject to disturbance from cattle and horse grazing and mowing activities year-round. No agricultural crop production is being removed from service. 4. By reclaiming the Site to wildlife habitat and groundwater fed ponds, the density and intensity of future development will be restricted. 5. Because the Project is in an unincorporated area, it complies with the County's objective discouraging large residential developments in unincorporated areas (locate urban development in urban areas). B. Locate urban development in urban areas. 1. This Project does not propose a change in zoning nor a subdivision within one - quarter mile of a municipal limit. 2. This Project does not include any urban -scale development that impacts urban services such as public water, sanitation, other utilities, or fire department. 20220517 PlanningQuestionnaire TT TELESTO To: Weld County Department of Planning Services Date: May 17. 2022 Page 12 3. There is no residential development as a part of this Project. 4. The Towns of Milliken and Johnstown have been notified in accordance with Chapter 19 and any requirements needed for Coordinated Planning Agreements will be met. LRM has met with the Town of Milliken to share plans for this application prior to submittal. C. Harmonize development with surrounding land uses. 1. The USR Map shows that mining offsets have been provided along W CR 48 '/2 and the neighbors to the south, along Hwy 257, along the railroad tracks adjacent to the Mad Russian Golf Course, and along the Big Thompson River Corridor. In addition to these physical buffers, LRM has taken the following steps to mitigate conflicts during mining: a. The Dust Abatement Plan, with the Environmental Health submittal, calls for standard operating procedures that will minimize dust impacts to surrounding homeowners. Neighbors communicated that dust was an important issue at several informal meetings. b. The Noise Evaluation Study, with the Environmental Health submittal, provides a baseline for existing noise background levels. Sound levels generated from project activities area predicted to be below Weld County noise limits at adjacent residential and commercial properties. Neighbors communicated that noise was an important issue at several informal meetings. c. The Property Values Study predicts no adverse impacts to property values d. The proposed operating hours ensure operations and associated noise, dust, and traffic occur during normal working hours. e. The post -mining land use is consistent with the "Greenbelt" designation shown along the Big Thompson River corridor on the Town of Milliken Framework Plan Map and therefore provides a permanent post -mining land use buffer. 2. This project does not include residential development. 3. As can be seen on the Landscaping Plan, submitted with this application, the post -mining Site plan permanently preserves both wetlands and wildlife habitat. 4. Access easements for existing oil and gas production on the property have already been established and will be maintained throughout the Project. 5. There are no known nonconforming lots associated with the Site. 6. No historical structures or landmarks were found on this property as documented in the attached correspondence from History Colorado. 7. This Site does not fall within the Johnstown Growth Management Area. However, the final reclamation is consistent with the "Greenbelt" designation shown on the Town of Milliken Framework Plan Map. 20220517 PlanningQuestionnaire TT TELESTO To: Weld County Department of Planning Services Date: May 17. 2022 Page 13 D. Collaborate on County -wide transportation and land use plans. 1. The Traffic Impact Study prepared for this project shows that all truck traffic between the Project Site and the existing Johnstown Ready -Mix batch plant falls well within the allowable levels the road service levels designated in the Weld County Functional Classification Map. 2. The final reclamation is consistent with the "Greenbelt" designation shown along the Big Thompson River corridor on the Town of Milliken Framework Plan Map. Sec. 22-2-40. Economic development goals and objectives A. Support compatible economic development opportunities. 1. The site will produce a total of 4.5 million tons of sand and gravel over the life of the mine. 2. The mining plan will produce up to 200,000 tons of sand and gravel a year, which will provide up to 130,000 yards of concrete for local construction proj ects. 3. The mine site will directly employ 6 workers on Site, and indirectly employ a minimum of 25 employees at the Johnstown Ready Mix site, along with associated contractors and subcontractors. LRM is a small, locally owned business, employing 95 employees in the front range. 4. The close proximity of the site to the existing Johnstown Ready Mix site will prevent the need to haul in aggregates from outside the County and avert extra the costs associated with outside sourcing. Sec. 22-2-50. Environmental goals and objectives A. Encourage responsible and sustainable water usage. 1. The Mine Plan allows for the mined materials to sit directly adjacent to the mining cells so it can efficiently drain back to the mining cells. 2. Loveland Ready -Mix has already has a Court approved plan that has allocated the water needed for exposed water surfaces created in the reclamation plan. 3. The Project does not include connecting the Site to any municipal water systems. B. Protect water quality within the County. 1. The Drainage Narrative and the Stormwater Management Plan show that adequate protection will be provided to ensure stormwater and process water from mining operations will not impact the Big Thompson River or any other drainage. 20220517 PlanningQuestionnaire TT TELESTO To: Weld County Department of Planning Services Date: May 17. 2022 Page 14 2. The mining operations have been designed to drain and capture all process water in the mining cells. Post -reclamation, surface water will continue to report to the interior of the Site. C. Minimize flood losses. 1. The project is located in the regulatory Floodway, where development is discouraged. 2. The Hydraulics Report submitted with the Flood Hazard Development Permit (FHDP) application, dated 9/13/21, shows that adequate spillways, armoring and setbacks are provided to minimize flood losses post -mining. 3. The Hydraulics Report shows that the ponds created as part of final reclamation actually decrease the effective 100 -year Base Flood Elevation (BFE) by 1.32 feet in the vicinity of the Site. 4. The County approved Floodplain Development Permit FHDP21-0024 (dated 11/30/21 and received on 1/18/22), conditional upon approval of the mining permit with the State and the County USR permit. Sec. 22-2-60. Natural resource goals and objectives A. Preserve wetlands and critical habitats. 1. The USR Map documents that no mining will take place within 100 feet of either side of the Big Thompson River. This will ensure that a wildlife corridor that includes existing cover in the way of trees and shrubs will remain throughout the project. 2. Mining the Site in phases with concurrent reclamation will minimize disruption to and provide for pockets of cover and access for wildlife throughout the duration of the project. 3. Reclamation includes the creation of permanent ponds and replacement of wetlands. 4. Reclamation includes the planting of willows and trees along the edges of the ponds providing additional vegetation and pockets of habitat cover. B. Support responsible energy and mineral development. 1. This project allows for extraction of a valuable construction material. 2. This project allows for responsible mining as the batch plant utilizing this product is close to the mining operation thus reducing impacts from hauling. 3. All practicable considerations have been taken into account during the design of this Project to minimize impacts on surrounding land uses during mining and to permanently conserve the land under the proposed post -mining plan. Sec. 22-3-10. Recreation and Tourism Element This section does not apply to the project. 20220517 PlanningQuestionnaire TT TELESTQ To: Weld County Department of Planning Services Date: May 17. 2022 Page 15 Sec. 22-4-10. Comprehensive Plan Map No rezoning requested as part of this project. This project does not fall within the Town of Milliken boundary and no annexation is requested with this project. On the County Comprehensive Plan Map, the Project falls within the Urban classification (orange) and limited Annexation classification (red) along the northeast edge of the property which includes the railroad tracks and Hwy 257. The checkered black overlay classifies Weld County Opportunity Zones and the blue hatch overlay classifies Floodplain Constraints. Weld County Comprehensive Plan Map Though not a Goal or Objective, the following Appendix 22-C response further supports that this proposal is consistent with the Weld County Comprehensive Plan. 20220517 PlanningQuestionnaire TT TELESTO To: Weld County Department of Planning Services Date: May 17. 2022 Page 16 Appendix 22-C — Right to Extract Mineral Resources Statement Weld County has some of the most abundant mineral resources, including, but not limited to sand and gravel, oil, natural gas, and coal. Under Title 34 of the Colorado Revised Statutes, minerals are vital resources because (a) the state's commercial mineral deposits are essential to the state's economy; (b) the populous counties of the state face a critical shortage of such deposits; and (c) such deposits should be extracted according to a rational plan, calculate to avoid waste of such deposits and cause the least practicable disruption of the ecology and quality of life of the citizens of the populous counties of the state. Mineral resource locations are widespread throughout the County and people moving into these areas must recognize the various impacts associated with this development. Often, mineral resource sites are fixed to their geographical and geophysical locations. Moreover, these resources are protected property rights and mineral owners should be afforded the opportunity to extract the mineral resource. Question 22 Explain how this proposal is consistent with the intent of the zone district in which it is located. (Intent statements can be found at the beginning of each zone district section in Article III of Chapter 23 of the Weld County Code.) Response 22 The Project Site is currently zoned Agricultural. The intent of this zone is stated in Section 23-3-10 of Weld County Code as follows: Agriculture in the COUNTY is considered a valuable resource which must be protected from adverse impacts resulting from uncontrolled and undirected business, industrial and residential land USES. The A (Agricultural) Zone District is established to maintain and promote agriculture as an essential feature of the COUNTY. The A (Agricultural) Zone District is intended to provide areas for the conduct of agricultural activities and activities related to agriculture and agricultural production, and for areas for natural resource extraction and energy development, without the interference of other, incompatible land USES. (Weld County Codification Ordinance 2000-1; Weld County Code Ordinance 2019-02) 20220517 PlanningQuestionnaire TT TELESTQ To: Weld County Department of Planning Services Date: May 17. 2022 Page 17 Question 23 Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. Response 23 The historic land use in the vicinity of the Dunn Pit is agricultural, rural residential, commercial (recreational golf course), and oil and gas production. The pre -mining use of the affected lands is pasture. The post -mining land use of wildlife habitat, groundwater sourced ponds, mitigated wetlands, and open space will be compatible with the Comprehensive Plan for the Town of Milliken as a Greenway and the existing uses in the surrounding area. Question 24 Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. Response 24 Prior to initiating the permitting process, LRM went beyond agency requirements and held voluntary meetings with neighbors to gather their questions and concerns to ensure they are addressed during the permitting process. LRM is taking specific actions to protect the health, safety, and welfare of inhabitants of the neighborhood and the County: Health: The proposed Project protects the health of neighbors and County inhabitants by: A. Containing stormwater runoff and reducing the risk of contributing sediment to the Big Thompson River 1.

Excavation will create little to no dust as the project is using wet -mining techniques 2. No aggregate processing will be conducted on Site 3. A Dust Abatement Plan is included with this submittal and a Mining Operations APEN (Form APCD-222) was submitted to CDPHE (dated 10/21/21). Construction Permit number 22WE0047F draft was issued 5/3/22 Safety: The proposal protects the safety of neighbors and County inhabitants by: A. Maintaining safe traffic patterns 1. The Transportation Impact Study (Delich Associates, 2021), submitted with the Development Review requirements, concludes the feasibility of the project from a traffic engineering standpoint and that traffic between the Project Site and the existing Johnstown Ready -Mix batch plant falls well within the allowable levels the road service levels designated in the Weld County Functional Classification Map 2. LRM is proposing a new access road, further east of the adjacent residence than the existing oil and gas access road B. Lowering flood risks 1. The Hydraulics Report submitted with the Flood Hazard Development Permit (FHDP) application, dated 9/13/21, shows that the ponds created as part of final reclamation decrease the effective 100 -year Base Flood Elevation (BFE) by 1.32 feet near the Site, lowering our neighbor's flooding risk C. Limiting public access to active mining areas 1. The permit area will be marked by existing fencing with signage. Once reclamation is established, signage will be replaced with appropriate "No Trespassing" signs 2. All entrances to the Site will be secured during nonworking hours with metal swing gates and a chain with company lock Welfare The proposal protects the welfare of neighbors and County inhabitants by: 20220517 PlanningQuestionnaire TT TELESTO To: Weld County Department of Planning Services Date: May 17. 2022 Page 19 A. Continuing employment of approximately 25 workers at Johnstown Ready -Mix and directly employing 6 workers at Dunn Pit B. Ensuring no harm to water rights holders 1. The SWSP request, submitted to the Division of Water Resources State Engineers Office and included with this submittal, addresses the exposure of groundwater, related evaporative depletions, and water consumed with the mining process. This process protects other water rights holders. C. Ensuring minimal impact to groundwater levels 1. Because of the wet mining operation, there will be no dewatering, and therefore, less impact to neighbor's groundwater levels 2. LRM will actively monitor Site groundwater levels and work to mitigate unacceptable changes caused by mining activity or reclamation D. Ensuring noise levels are within acceptable limits 1. The Noise Evaluation Study, submitted with the Environmental Health requirements, provides a baseline for existing noise background levels. Sound levels generated from project activities area predicted to be below Weld County noise limits at adjacent residential and commercial properties without mitigation E. Not contributing light pollution 1. LRM will only operate during daylight hours and will not add on -site lighting Question 25 Describe any irrigation features. If the proposed use is to be located in the A (Agricultural) Zone District, explain your efforts to conserve prime agricultural land in the locational decision for the proposed use. Response 25 There are no irrigation ditches located on Site. The Project will not infringe on existing agricultural production in the area. Question 26 Explain how this proposal complies with Article V and Article XI of Chapter 23 if the proposal is located within any Overlay Zoning District (Airport, Geologic Hazard, or 20220517 PlanningQuestionnaire TT TELESTQ To: Weld County Department of Planning Services Date: May 17. 2022 Page 20 Historic Townsites Overlay Districts) or a Special Flood Hazard Area identified by maps officially adopted by the County.

May 2022 1.0 BACKGROUND 1.1 Project Overview Loveland Ready Mix (LRM) proposes the development of a new sand and gravel mine (Dunn Pit; Project) at the northwest corner of Colorado Highway 257 and Weld County Road 48 '/2 in Weld County (Site, Figure 1). LRM is applying to Weld County for Use by Special Review (USR) for the Dunn Pit aggregate mine. The approximately 114 -acre Site is currently undeveloped and is used for cattle grazing and oil extraction. The Site is Zone A — agricultural. Specific proposed development activities include: • Constructing a Site access road and bridge from the proposed Site entrance northward across the Big Thompson River • Excavating three aggregate mine cells to a depth of approximately 30 feet, which will become unlined, groundwater -fed lakes • Hauling the mined aggregate to LRM's permitted Johnstown concrete, batch plant for processing • Reclaiming the mined slopes above the groundwater table and establishing new wetlands in and around the mined cells During mining, LRM will temporarily stockpile mined aggregate to allow the material to drain before hauling. LRM will conduct reclamation concurrent to mining and anticipates no long-term storage of reclamation materials in the floodplain. Figure 2 shows the ultimate mine plan and estimated timing for the Project. Reclamation will occur concurrently with mining. No permanent structures will be erected during the Project besides the Big Thompson River bridge. The bridge will remain in place after mining is complete. 2.0 OBJECTIVES Weld County USR Planning Questionnaire question 5 asks the applicant to "Describe the surrounding land uses of the site and how the proposed use is compatible with them." Loveland Ready -Mix 1 20220516_properlyvaluesstudy. docx May 2022 TELESTO The straight -forward study included herein will show that the proposed Project is compatible with surrounding land uses, and will address concerns expressed by the nearby Mad Russian residential development, and other similar neighborhoods in Northern Colorado, that gravel mines have an adverse impact on residential neighborhoods by answering the following two questions: • Are aggregate mining operations compatible with residential neighborhoods? and • Does the presence of aggregate mining operations result in a substantial negative impact on neighboring property values? Recognizing that compatibility is, in part, a subjective term, and that property values are influenced by a large number of factors, this study does not aim for mathematical precision. Rather, it pursues a common sense or general and representative answer to these two questions. 3.0 EXISTING CONDITIONS The Project Site is generally surrounded by grazing and agricultural lands on the east, south and west. A number of rural residential properties are interspersed within the agricultural lands with a majority being along Weld County Road 48 '/2. A residential development and golf course is located across a rail line to the north of the Site (Mad Russian Golf Course). The Project Site is generally flat, with gentle slopes toward the Big Thompson River. The river flows from west to east and generally bisects the Site. Several oil and gas wells, a tank battery and associated roads and pipelines are located on Site. However, the bulk of the approximately 114 acres is currently being used for cattle grazing. 4.0 DEVELOPMENT ADJACENT TO AGGREGTE MINING Development of lands as residential neighborhoods in Northern Colorado happens through infill development, at the perimeter of existing communities, or through the conversion of existing open land to residential use. At a number of locations within Northern Colorado, residents have the opportunity to live in neighborhoods in close Loveland Ready -Mix 2 20220516_properlyvaluesstudy. docx May 2022 TELESTO proximity to aggregate operations, either ongoing or reclaimed. That Larimer and Weld County residents often choose to live adjacent to active aggregate operations is an indication that residential neighborhoods and aggregate operations can be compatible land uses. Sand and gravel mining, almost always located in alluvial valleys, creates open space around residential neighborhoods, which is preserved after mining is complete through reclamation practices. Several examples of residential neighborhoods adjacent to aggregate mining and batch plant operations exist in Larimer and Weld Counties. Aerial images showing five representative neighborhoods are provided in Appendix A: 1. Bucking Horse Neighborhood in east Fort Collins is located adjacent to an Aggregate Industries batch plant. This neighborhood consists of residential houses, commercial lots, and an organic farm. The batch plant was running before construction started in this recently developed neighborhood. 2. Mariana Butte Planned Unit Development (PUD) in southwest Loveland is located adjacent to some of the Loveland Ready -Mix gravel pits in Loveland and within 0.1 mile from the batch plant. Many of these homes were put in place after the Loveland Ready -Mix batch plant and mining operations were underway in Loveland. 3. The Millennium SW Neighborhood in southeast Loveland is adjacent to Kauffman MRD, and within 0.5 mile of the Front Range Ready -Mix batch plant and within 0.6 mile of the Kauffman & Son batch plant. Many of these homes were constructed after the aggregate mining and batch plants. 4. The River West PUD and Ridge West PUD in west Windsor are located adjacent to Connell resources. 5. The Poudre River Ranch Neighborhood in Greeley is located within 0.5 mile of Camas Colorado/Aggregate Industries. The Millennium SW and Kauffman MRD neighborhoods in southeast Loveland are a typical example, shown at right. These two neighborhoods include a larger single- and multi- family community, and an estate lot 1 subdivision. The Big Thompson River is to the south, the east Loveland shopping district lies to the north, and 3 "u!!?=4 MILLENNIUM SW Loveland Ready -Mix 20220516_properlyvaluesstudy. docx May 2022 TELESTO downtown Loveland to the west. Significant gravel mining has occurred in the Big Thompson alluvium south of these neighborhoods, and current operations by Kauffman and Son and by Front Range Ready -Mix are located proximate to these neighborhoods. It is clear that these neighborhoods have become attractive to residents for a variety of reasons, and that the aggregate mining operations, historical and existing, are compatible with the range of residential opportunities that exist in these neighborhoods. Similar observations can be made for the Bucking Horse neighborhood in east Fort Collins, the River West PUD and Ridge West PUD neighborhoods in west Windsor, and the Poudre River Ranch neighborhood in west Greeley, all adjacent to active aggregate operations within the Poudre River alluvium. A multi -use neighborhood near Mariana Butte and the Big Thompson River has grown up around historical and current operations of Loveland Ready -Mix, south of Highway 34 and west of Namaqua Road in southwest Loveland. This neighborhood includes an elementary school, commercial property, recreation, multi -family housing, and single-family homes, all proximate to reclaimed and active aggregate mining. 5.0 PROPERTY VALUES COMPARISON STUDY Telesto conducted a general study evaluating assessed property values for homes next to the Overland Trail Ponds aggregate mining operations adjacent to the Poudre River just south of LaPorte, Colorado in Larimer County. The Overland Trail Ponds region was chosen for this study because of the large number of homes in close proximity to the extensive mining operations along this reach of the Poudre River. Three neighborhoods adjacent to aggregate mining were selected for study: Stagecoach, Solar Ridge, and Saddleback. All three neighborhoods existed prior to the beginning of operations at Overland Trail Ponds. The study compared home values for lots with views of the Loveland Ready -Mix 4 20220516_properlyvaluesstudy. docx May 2022 TELESTO Overland Trail Ponds aggregate mining to home values in the same neighborhood for lots without direct views of the aggregate mining. Additionally, annual increases in property values for 45 view lots from these three test neighborhoods were compared to homes in similar neighborhoods not adjacent to aggregate mining operations. The two selected control neighborhoods were the Ponds at Overland Trail and Poudre Overlook. It is believed that the Overland Trail Ponds region is a good analog for the changes in property values that may be expected for the Mad Russian Golf Course neighborhood upon the development of the proposed Project because: • The homes on the south side of the Mad Russian Golf Course overlook the proposed Project in a similar manner to those of the Stagecoach, Solar Ridge, and Saddleback neighborhoods • The residential developments are of similar kind, age, and value • Both regions are analogous of typical semi -rural residential developments near riparian areas of Northern Colorado 5.1 Approach Figures 3 and 4 show the location of the neighborhoods compared in this study. Saddleback, Solar Ridge, and Stagecoach neighborhoods contain houses that have a direct view to the north of the aggregate mining features. The two control neighborhoods are both in west Fort Collins and are very close or relatively close to the three test neighborhoods. The Ponds at Overland Trail neighborhood is approximately two miles south of Poudre Overlook, and Poudre Overlook is immediately to the south of Stagecoach and west of Solar Ridge. Relatively large neighborhoods were selected as control samples to minimize the number of variables that affect value: same builder, similar home and neighborhood amenities, and similar construction timeframe. Home values were determined from the Larimer County Assessor's Real Property Records online database. This allowed a consistent valuing methodology for all neighborhoods, provided a sufficient sample size with which to test the hypothesis, and readily available data that span the timeframe of interest. Annualized rates of increase were calculated with the formula, P2 = Pi(1+i)", where P2 is the home value as of the Loveland Ready -Mix 5 20220516_properlyvaluesstudy. docx May 2022 TELESTO 2021 property assessment date, Pi is the home value at the beginning date (chosen to be the 2000 biennial property assessment date, or later date depending on the date of home construction), i is the annualized rate of increase, and n is the number of years in the calculation. A total of 15 view lots were selected in each of the Solar Ridge, Stagecoach and Saddleback neighborhoods, 15 non -view lots were selected in each of these three neighborhoods, and 30 lots were selected from each of the Ponds at Overland Trail and Poudre Overlook neighborhoods. Lots were selected across a geographic spread in each neighborhood. A total of 120 homes/lots were selected and included in the comparison tables. 5.2 Results A spreadsheet was used to calculate the annualized rate of lot value increase for each of the 120 lots in the study. A description of the calculation and results is included in Appendix B. The home values for each of the 15 view lots selected in the study for each of the three test neighborhoods were compared to the home values for each of the 15 non - view lots in the three test neighborhoods. Table 4-1 presents the results of this comparison. Table 4-1 Comparison of Home Values, Lots With Direct Views of Aaareaate Mining Versus Lots Without Direct Views Neighborhood Name Average Home Value (2021), 15 lots WITH direct Average Home Value (2021), 15 lots WITHOUT views direct views Saddleback $597,160 $559,800 Solar Ridge $700,400 $747,713 Stagecoach $339,817 $342,650 Many variables affect home values and definitive conclusions cannot be made; however, general conclusions regarding compatibility and substantial impact can be discussed. For the Saddleback neighborhood, lots with views of the Overland Trail Ponds aggregate mining were greater in value than lots without those views. For Solar Ridge, this Loveland Ready -Mix 6 20220516_properlyvaluesstudy. docx May 2022 TELESTO relationship was reversed. Lots in the Stagecoach neighborhood were essentially the same value regardless of whether they overlooked the Overland Train Ponds or not. Table 4-2 compares the annualized rate of increase in home value, almost in every case from the 2000 property assessment date through 2021, for lots with direct views of the aggregate mining to lots without those direct views, within the same neighborhoods. Table 4-2 Comparison of Annualized Rates of Increase (ARI) for Lots With Direct Views of Aggregate Mining Versus Lots Without Direct Views Neighborhood Name ARI, View Lots ARI, Non -View Lots Difference, in % Points Saddleback 3.5% 3.9% -0.4 Solar Ridge 4.3% 4.2% +0.1 Stagecoach 5.6% 5.6% 0.0 Average 4.6% 4.7% -0.1 The net result from comparing the annualized rate of increase of property values for the 45 lots with direct views of aggregate mining to 45 lots in the same neighborhoods without those direct views was -0.1%; each subset experienced a 4.6% to 4.7% per year increase in property value over the 21 -year pre -mining to present time period. Table 4-3 compares the annualized rate of increase in home value for the 45 view lots in the test neighborhoods with the annualized rate of increase in home value for 60 lots in the control neighborhoods over generally the same time period. Table 4-3 Comparison of Annualized Rates of Increase (ARI) for Lots With Direct Views of Aggregate Mining Versus Lots in Control Neighborhoods Neighborhood Name ARI Average Property Value Saddleback (view lots) 3.5% $597,160 Solar Ridge (view lots) 4.3% $700,400 Stagecoach (view lots) 5.6% $339,817 Average 4.6% Ponds at Overland Trail 4.2% $539,047 Poudre Overlook 4.3% $583,650 Average 4.3% Loveland Ready -Mix 20220516_properlyvaluesstudy. docx 7 May 2022 TELESTO The net result from comparing the annualized rate of increase of property values for the 45 lots with direct views of aggregate mining to 60 lots in the two control neighborhoods was a 0.3% higher value for the view lots in the three test neighborhoods. 6.0 CONCLUSIONS We are cautionary about overstating conclusions from this general study. Many variables affect property values that are very difficult to adequately address in a property values survey. However, general conclusions regarding compatibility and substantial impact can be discussed. In a number of locations within Northern Colorado, residents have opportunity to live in neighborhoods in close proximity to aggregate operations, either ongoing or reclaimed. Five neighborhoods were identified as examples of this situation. That many Larimer and Weld County residents choose to live adjacent to active aggregate operations is an indication that residential neighborhoods and aggregate operations can be compatible land uses. Our comparison of assessed property values for 45 properties with direct views of the Overland Trail Ponds aggregate operations to properties without direct views of aggregate operations indicated little to no substantial negative impact on absolute property value or on annualized increases in property values. Comparison of property values for homes in the same neighborhoods, both with and without views of aggregate mining, indicated no clear trend. In one of the three test neighborhoods, view properties had higher values than non -view properties; in the other neighborhoods the trend was reversed. Comparison of annualized increases in property values for lots with direct views of aggregate mining operations to non -view lots in the same neighborhoods, and to lots in control neighborhoods, showed little to no difference. That no change or small changes were observed is an indication that substantial adverse impact in property values was not Loveland Ready -Mix 8 20220516_properlyvaluesstudy. docx May 2022 TELESTO seen for properties that are in a comparable situation as the neighboring properties to the proposed Dunn Pit aggregate mining project.

Tigges Date: 05/13/22 Calculation Documentation Problem Statement: Assertions have been made that the operation of sand and gravel mines and concrete batch plants have a negative impact on adjacent property values. Loveland Ready -Mix Concrete, Inc. (LRM) proposes the construction and operation of a new sand and gravel mine (Dunn Pit) at the northwest corner of Colorado Highway 257 and Weld County Road 48 % in Weld County. The proposed mining operations will include the recovery of sand and gravel to produce concrete. The property proposed for the aggregate mine is depicted in the figure at right. Existing homes and a golf course are located to the north of the 114 -acre property. Objectives: 1. Compare the property values for northern Colorado homes located adjacent to aggregate mining (test populations) against comparison homes not located adjacent to aggregate mining (control populations). 2. Determine whether, in general, a substantial adverse impact in home values can be attributable to home location proximate to aggregate mining. Approach: 1. Identify a residential neighborhood that overlooks a gravel mine and was constructed prior to mining. 2. Identify homes to be used in the analysis (approximately 30 in each test neighborhood). Both homes that are adjacent to mining and not adjacent to mining will be selected. 3. Estimate home values from county assessor's real property records. This will allow a consistent valuing methodology, sufficient sample size to test the hypothesis, and readily available data that span the timeframe of interest. 4. Calculate the annualized rate of increase in property value using P2=P1(1+i)n, where P1=beginning property value, P2=2021 property value, n=number of years between property values, i=annualized rate of increase 5. Compare the annualized rates of property value increase for homes adjacent to mining to those not adjacent to mining and between neighborhoods adjacent to mining to control neighborhoods. Data and Assumptions: 1. Assessor's office records provide a reasonable estimate of true market property values adequate for the purposes of the comparison. 2. The test populations chosen will be adjacent to the Overland Trail Ponds gravel pits and the Poudre River in Larimer County, approximately 23 miles to the NW of the Dunn Pit. 3. Suitable control neighborhoods include the Ponds at Overland Trail and Poudre Overlook. These control neighborhoods are believed to be comparable to the test neighborhoods since they are of similar age, region, and have comparable home values.

This set of calculations is not intended to results in precise conclusions, but is a simple approach to answering the question "do homes with views of gravel pits see a pre -mining to post -mining substantial decrease in home values relative to comparable homes?" The comparisons of home values and of annualized rates of increase within the 3 test neighborhoods, and the comparison of ARIs for view lots within the test neighborhoods to lots in comparison/control neighborhoods are summarized as follows: • View lots are more valuable than non -view lots in 1 of the 3 test neighborhoods • 45 view lots in the test neighborhoods had an ARI of 4.6% from 2000 (pre -mining) to 2021 (current) and 45 non -view lots had an ARI of 4.7% from 2000 to 2021 • 45 view lots in the test neighborhoods had an ARI of 4.6% from 2000 to 2021, compared to 30 lots in the Ponds at Overland Trail with an ARI of 4.2% and to 30 lots in Poudre Overlook at 4.3% We conclude that lots with direct views of gravel pits do not experience a substantial negative impact in home values from pre -mining to current conditions compared both to non -view lots in the same neighborhoods and to lots in comparable/control neighborhoods.

(Telesto) conducted a baseline groundwater assessment to: • Support geotechnical analyses associated with bank stability during sub- aqueous mining and closure • Support wetland mitigation designs • Assess potential impacts associated with the proposed Loveland Read - Mix's Dunn Pit (Pit) sand and gravel mine. The proposed sand and gravel mine has the potential to modify groundwater flow patterns and affect surrounding groundwater levels. Telesto developed a groundwater conceptual site model (CSM) to quantify and summarize the available data and mechanics of the existing groundwater system. The CSM formed the basis of a numerical representation (i.e., numerical model), which Telesto calibrated using measured groundwater level data and area features such as levels of the Big Thompson River and surrounding irrigation ditches. The calibrated numerical model then simulated mining impacts to surrounding groundwater levels, flows through wetlands and the piezometric surface used in geotechnical stability analyses. The numerical model simulates that the unlined mine cells will "flatten" gradients immediately adjacent to the pits, and have a drawdown upgradient and a small mounding downgradient. No significant injury to any registered well owner is anticipated. The Dunn domestic well will incur the largest drawdown (predicted at 3.8 feet, slightly over 10% of its completed depth). However, resulting gravel pit lakes will serve to enhance the wells' production efficiency.

(Telesto) conducted a groundwater study to assess potential impacts associated with the proposed Loveland Read -Mix's Dunn Pit, a proposed aggregate mine. Although LRM will mine the resource sub-aqueously and will not dewater pits, there is a potential to change the groundwater flow regime. To gain a thorough understanding of potential outcomes of the proposed mining project, Telesto developed conceptual models to summarize the available data, and hydraulics of the Big Thompson alluvial groundwater system. From the conceptual model, Telesto formulated a numerical representation (i.e., numerical model) which they calibrated to local groundwater level data. They utilized the numerical model to predict potential impacts on the groundwater system. The groundwater model formed a basis for assessing the needs for mitigation plans and management techniques to protect neighboring groundwater resources. 1.1 Project Description LRM proposes a new aggregate mine adjacent to Weld County Road (WCR) 481/2, immediately west of Colorado Highway 257 near Milliken, Colorado. LRM seeks approval for the Project through the Colorado Natural Resources Department, Division of Reclamation, Mining, and Safety (DRMS), and Weld County's Use by Special Review process. LRM currently leases the site for cattle pasture as it has since purchasing the property in the early 1980s. LRM owns approximately 114 acres of which approximately 75 acres encompasses the proposed mining area. LRM will reclaim mined slopes above the water table soon after mining pit areas and will establish new wetland areas in select portions of the pits. The proposed Dunn Pit straddles the Big Thompson River (River), which is responsible for the deposition of the alluvial materials sourcing aggregate. Current and historical aggregate mining is prevalent along the River as seen in Figure 1. The site is relatively flat with topography generally mimicking the Big Thompson River. As seen in Figure 2, surrounding properties include to the: LRM 20220128_revlgw_report tg January 2022 TELESTO • North A railroad right of way Golf course community • East • South • West Highway 257 right-of-way Agricultural properties and home Weld County Road 48 '/2 right-of-way Six homes and outbuildings on agricultural properties Home and outbuildings on agricultural property Large agricultural fields Big Thompson River floodplain Also shown in Figure 2 are key features affecting groundwater flow in the area including: • The Big Thompson River • Hill and Brush Ditch • Big T and Platte Ditch • Historical aggregate pit lakes • Permitted and suspected water wells 1.2 Objectives The objectives of this report are to: • Describe the groundwater system associated with the Project • Predict potential impacts to groundwater and its users, including: Changes in groundwater elevations that would affect residents or well users Changes in flow paths for potential migration of impacted water • Provide mitigation strategies should impacts (predicted or realized) be unacceptable 1.3 Approach This report consolidates available information on climate, geology, surface water, and groundwater to develop a conceptual hydrogeologic model for the proposed Project and adjacent area. A two-dimensional numerical groundwater flow model quantifies the conceptual model incorporating relevant aspects of the hydrologic system. To improve its LRM 20220128_revlgw_report tg 2 January 2022 TELESTO predictive capabilities, the numerical model is calibrated to known hydraulic heads measured in on -site monitoring wells. The focus of this effort is to provide a defensible technical basis for predicting groundwater -related impacts associated with commencement of mining, on -going operation, and future closure of the Pit, and to provide an evaluation tool for developing mitigation strategies if required. 2.0 BACKGROUND Aggregate mining is currently and historically prevalent along the Big Thompson River corridor. As entities extracted and processed the alluvial deposits into construction materials, the sites were reclaimed for residential, agricultural, wildlife habitat, or water storage uses. In the reclamation processes, groundwater conditions reverted to conditions similar to the pre -mining status. Figure 1 shows the locations of local aggregate mines that beneficiated Big Thompson River alluvium; the Colorado Department of Natural Resources, Division of Reclamation, Mining, and Safety (DRMS) maintains a map of aggregate mines (i.e., construction material sites) (CDRMS, 2021). Following cessation of mining, many pits were reclaimed as lakes, or reverted to open space used for grazing or wildlife habitat. 2.1 Geologic Setting The Project lies in the Colorado Piedmont physiographic province (Palkovic, et al., 2018), at the northwester margin of the Denver sub -basin within the Denver-Julesburg basin, with the Northern Rocky Mountain Front Range uplift to the west (Kirkham & Ladwig, 1980). The Project terrain is characterized by the Big Thompson River floodplain, and heavily influenced by the Little Thompson and South Platte River confluences to the east. To the north, outcrop of the transitional Pierre Shale formation underlies the sandstones of the Fox -Hills formation, exposed in the bluffs bordering the Big Thompson River. Both are topped by eolian deposits of the upper Holocene and Pleistocene. On -site alluvial deposits consist of Holocene and upper Holocene deposits as shown in Figure 3. Terrace gravel deposits are prevalent on the upper topography to the south of the Big T and Platte Ditch. LRM 20220128_revlgw_report tg 3 January 2022 TELESTO The Project overlies unconsolidated alluvial deposits of Quaternary age deposited during natural meandering of the ancestral Big Thompson River system. The alluvial sands and gravel were eroded from the Rocky Mountains to the west and deposited along broad areas of the river valley. Alluvial deposits underlying the Project care poorly sorted (well graded) granite -sourced clays, silts, sands, and gravel with very few cobbles. The Big Thompson alluvial deposits lie on an erosional contact with the transitional member of the Cretaceous Pierre Shale. The Pierre Shale is relatively impermeable and considered a bedrock aquiclude when evaluating alluvial -bedrock groundwater interactions. 2.2 Hydrologic Setting 2.2.1 Climate The Site is in a semi -arid region of the northern Front Range area of Colorado. The regional climate is summarized by data obtained from the Western Regional Climate Center web site (WRCC, 2017). 2.2.2 Surface Water Regional Drainage The Site is located within the 835 square -mile Big Thompson river basin, a tributary to the South Platte River that generally drains to the east. Within Weld County, the River drains a total area of approximately 86 square miles. Perennial flow exists in the River from the mouth of the Big Thompson canyon downstream through Loveland on through the town of Milliken. In the spring and early summer, the Big Thompson recharges an extensive valley -fill alluvial aquifer. Infiltration from irrigation diversions and roadside swales adds to the alluvial aquifer recharge from mid -summer through early fall. Dry season river flows are minimal and consist primarily of municipal wastewater plant discharges, and irrigation sourced groundwater return flows from the extensive valley -fill alluvial aquifer. LRM 20220128_revlgw_report tg 4 January 2022 TELESTO Local Drainage Site ground surface elevations range from 4,754 feet in the northwest corner of the property to 4,735 feet near the railroad bridge over the Big Thompson river. It lies entirely in the 100 -year Big Thompson river regulatory floodplain as defined by FEMA. Surface runoff from the site and surrounding area occurs as sheet flow off pasture lands or is captured locally in the few small interior wetlands. Offsite storm water runoff is diverted by the railroad to the north and Weld County Road 48 '/2 to the south. The Big Thompson river serves as the main conduit for the removal of stormwater. Once mining operations begin, on -site runoff that historically flowed across the Site will be directed to and retained in the Pits, which will be excavated to 25 -to -30 -foot depths below the current ground surface. Because LRM will mine the pits wet, and plans to leave the pits unlined after mining, captured stormwater will return to the Big Thompson river via groundwater return flows. 2.2.3 Groundwater Regional Groundwater is a source of water for municipal, domestic, agricultural, and industrial uses within Weld County, especially east of Greeley and outside of the South Platte River basin; however, diverted river flows and trans -mountain diversions form the bulk of the water sources for uses in urban areas along the Front Range. The viability of the groundwater resource is dependent on characteristics of the geologic unit from which groundwater is extracted. Well yields (flow rates expressed in gallons per minute) of groundwater wells are controlled by the permeability of the host rocks. • Metamorphic and igneous rocks have relatively small well yields [1 and 15 gallons per minute (gpm)], except in highly weathered granitic rocks that can produce higher yields. Metamorphic and igneous rocks do not provide groundwater in the Project area and will not be penetrated by any proposed mining activities • Marine sedimentary rocks are generally poor aquifers in Weld County. However, fractured carbonate rocks, which most commonly occur near LRM 20220128_revlgw_report tg 5 January 2022 TELESTO major fault structures, can locally provide significant well yields. Marine sedimentary rocks do not provide groundwater in the Project area and will not be penetrated by any proposed mining activities • Wells completed in consolidated and semi -consolidated Tertiary and Cretaceous clastic deposits can yield up to several hundred gpm. These deposits will not be penetrated by any proposed mining activities and do not provide groundwater in the Project area • Unconsolidated stream alluvium along major stream channels range in thickness from 5 to 30 feet thick and can locally provide well yields up to several hundred gpm (Topper, 2003). Properties adjacent to the Site have shallow groundwater wells completed in alluvium. Local Local groundwater flow and levels are strongly influenced by the Big Thompson river, historical aggregate pits that are now unlined lakes or small wetlands. Telesto installed 10 monitoring wells on the site as described in Appendix A. Early summer 2021 depth -to - groundwater measurements are summarized in Figure 4, which depicts the resulting groundwater elevations. LRM plans to monitor these wells monthly for a full year after installation and quarterly thereafter. Also shown in Figure 4 are four permitted wells (CDWR, 2021). The Wagner and Dunn wells are registered as domestic use. The Nelson well is registered for irrigation use. Alluvial groundwater generally follows the flow direction of the Big Thompson river. The Big T and Platte River and the Hill and Brush ditches contribute to groundwater flow during the irrigation season. Neary by historical gravel pits and wetland areas function as evaporative sinks. Water Quality Telesto collected initial samples from the site monitoring wells south of the Big Thompson River on June 8 and 9, 2021. Samples north of the river were thwarted by high flows until August 5, 2021. Laboratory reports are provided in Appendix B. Groundwater is slightly alkaline with a pH ranging between 8.01 to 8.24. The dominant anion is sulfate, while cations are balanced towards calcium and magnesium (Figure 5). Baseline groundwater quality in MW -04 and MW -08 meets Colorado's Water Quality Control Commission (WQCC) Regulation No. 41 standards. The baseline water quality in remaining wells had LRM 20220128_revlgw_report tg 6 January 2022 TELESTO select exceedances of iron, manganese, and uranium (see Appendix B). Iron and manganese are roughly an order of magnitude higher than the standard, while uranium hovers around the standard. This is common along Colorado's Front Range, especially where alluvial aquifers overlie the Pierre Shale formation. Telesto collected samples from select monitoring wells and requested analyses for benzene, toluene, ethylbenzene, xylenes (BTEX) and total petroleum hydrocarbons (TPH). All samples were non -detect. 2.3 Conceptual Model A conceptual groundwater flow model is a graphical, semi -quantitative description of the parameters and conditions that control groundwater flow. Figure 6 displays the conceptual groundwater flow model associated with the Site as limited to the model boundary shown. Components of the conceptual model are represented in the numerical flow model as various boundary conditions and variables. 2.3.1 Boundary Conditions Model Top The top of the conceptual model is defined by the topography (represented by the most recent LiDAR topography), and a variable flux boundary. The flux represents natural recharge on non -irrigated areas, and excess irrigation that percolates below the rooting zone in irrigated areas. The bounding condition is assumed to be relatively constant throughout the year as irrigation induced percolation will be attenuated on its vertical path to the groundwater table. Likewise, naturally occurring precipitation driven percolation is assumed to be constant throughout the year. Model Bottom The bottom of the conceptual model is the Pierre Shale. As described previously, the Pierre shale acts as an aquitard and is therefore represented as a no -flow (i.e., zero flux) boundary. LRM 20220128_revlgw_report tg 7 January 2022 TELESTO Perimeter The southern perimeter of the model is an assumed flow line and is defined by the contact of the Big Thompson River alluvium and the terrace gravels (Qa3 in Figure 3) to the south, which is represented as a no -flow boundary. The northern boundary is a no -flow boundary defined by the contact with bedrock. The eastern and western boundaries of the model are flux boundaries. To represent this flux, constant head boundaries are used that are related to the stage in the river. Internal Boundaries Within the area of interest, several types of hydrologic boundaries exist related to groundwater flow. Area ditches provide recharge and discharge opportunities for groundwater. Leakage rates can range from 10 to 25% of the flow in the ditch. Un-sealed gravel lakes and active mining pits become discharge points for the alluvial aquifer. Evaporation can be a significant sink in the summer when evaporation rates can reach up to 5.74 inches in the month of July (CDWR, 2011). One irrigation well is known to exist west (and upgradient) of the site. 2.3.2 Hydraulic Parameters Porosity/Storage Coefficient The storage coefficient dictates the amount of groundwater that moves in and out of the pore space as aquifer conditions change (e.g., pumping from a well or cessation of irrigation returns). Storage coefficients for the Big Thompson alluvium range from 15 to 25%. A typical value used in the Milliken area is 20% (CDWR, 2017). Saturated Hydraulic Conductivity The saturated hydraulic conductivity dictates how easily groundwater moves through porous media (i.e., alluvium in this case). Transmissivity is a product of the saturated aquifer thickness and hydraulic conductivity. The CDSS (CDWR, 2017) indicates that the hydraulic conductivity in the Milliken area is around 250 feet/day. LRM 20220128_revlgw_report tg 8 January 2022 TELESTO Telesto performed aquifer pumping test analyses on two of monitoring wells installed at the Dunn site. Saturated hydraulic conductivity from testing ranged from approximately 81 to 95 ft/day (0.028 to 0.034 cm/sec). Appendix C documents the monitoring well aquifer tests. 3.0 NUMERICAL MODEL FRAMEWORK 3.1 Numerical Modeling Code Telesto chose the widely accepted groundwater flow model, MODFLOW 2005 (Harbaugh, 2017). Groundwater flow is mathematically simulated utilizing a block -centered, finite difference approach to solve the corresponding governing differential equations. MODFLOW 2005 is a series of modular subroutines that are highly independent of one another that allows flexibility in simulating a multitude of boundary and geometric conditions. Modeling input was accomplished with a variety of tools including Model Muse (Winston, 2009), Global Mapper 16 (Blue Marble Geographics, 2015) and internal codes developed by Telesto. 3.2 Numerical Modeling Domain The modeling domain is best described as a rectangular grid oriented parallel to the main direction of groundwater flow. It is two-dimensional, variable thickness, unconfined model. In MODFLOW, the modeling coordinates start in the upper left corner and are defined by rows and columns. The upper left corner of the model is located at geographical northing of 40° 21' 59.9324" N and easting of, 104° 53' 58.5849" W. The modeling grid is oriented clockwise around the upper left corner at 105° 31' 59.3" from true north. The model domain is 18,105 feet (3.429 miles) in the x -dimension and 11,500 feet (2.178 miles) in the y -dimension. The model domain is gridded in the x -dimension by 195 columns ranging from 25 to 500 feet in width, and in the y -dimension by 143 rows ranging from 25 to 500 feet. The extents of the model are sufficiently large as to avoid unduly influencing the hydraulics near the Site and areas of concern. Figure 7 displays the model domain oriented against Colorado State Plane North coordinates. LRM 20220128_revlgw_report tg 9 January 2022 TELESTO 3.3 Numerical Model Boundaries Model boundaries define the hydrologic conditions of the aquifer throughout the model domain. As described in Section 2.3.1, various boundary conditions exist. Where bedrock outcrops or sub -crops, the model is inactive or has a zero -flux boundary. Two rivers exist within the model domain: the Big Thompson and the Little Thompson rivers. The two main ditches influencing groundwater near the Site are the Hill and Brush ditch and the Big T and Platte. Rivers and ditches are treated as general head boundaries using the MODFLOW river package. 3.4 Model Parameters Aside from geometry, the main model parameters include: • Hydraulic conductivity — 8 to 250 ft/day • Aerial recharge — estimated at 5 to 10% of precipitation • Lake surface evaporation — (NOAA, 2015) • River Elevation — USGS topography, site survey topography 3.5 Model Timeframe For this effort, Telesto chose to utilize a steady-state model representing the spring -season groundwater levels (highest levels). The steady-state model provides the basis for a series of predictive models that simulate groundwater behavior as the ground water is exposed in the mining cells as mining progress. Each phase of the three cells is modeled as a constant head boundary. 4.0 MODEL CALIBRATION Calibration is the process by which model parameters are adjusted within the range of measured/known values until a set of "targets" is matched. For a groundwater model, targets are drainage discharge rates, increases or losses to surface water features, but most commonly groundwater elevations measured in wells. LRM 20220128_revlgw_report tg 10 January 2022 TELESTO 4.1 Calibration Targets For this modeling effort, the calibration targets are the spring groundwater elevation measurements from the Site monitoring wells. Table 1 lists the information for Site monitoring wells, including the targets (groundwater elevations) used in the model calibration effort Table 1 Monitoring Well Information Well Name Easting1 Northing Stickup (ft) Ground Surface Elevation (ft) Depth to Water Measured 5/7/21 (ft) Groundwater Elevation (ft) MW -01 3173581 1368879 3.27 4746.348 9.25 4740.37 MW -02 3173544 1370047 3.32 4748.483 8.52 4743.28 MW -03 3173028 1370961 3.2 4752.183 9.05 4746.33 MW -04 3174494 1369669 3.54 4747.495 9.55 4741.49 MW -05 3174587 1369091 3.74 4742.581 10.21 4736.11 MW -06 3175284 1367834 3.05 4740.507 7.87 4735.69 MW -07 3176101 1367902 2.76 4737.311 6.90 4733.17 MW -08 3175991 1368476 2.83 4739.284 8.30 4733.81 MW -09 3174529 1368109 3.33 4741.733 7.62 4737.44 MW -10 3174626 1369928 3.53 4747.935 11.21 4740.26 4.2 Calibration Results Telesto built the model in a step -wise fashion, adding boundaries (ditches, drains, ponds) one model -run at a time. Once the model was running, we adjusted boundary conditions and hydraulic conductivity within reasonable ranges until the model represented the distribution of measured groundwater elevations in the monitoring and neighborhood wells. Simulated groundwater elevations from the model cells representing wells on the date measurements are compared against measured elevations in Figure 8. Also, shown in Figure 8 are results of regression analyses (coefficient of determination -r2, regression line slope and intercept) and the sum of the difference squared between simulated and measured groundwater elevations indicating the capacity of the model to accurately simulate groundwater levels in the wells. The model simulations of MW -04 and MW -10 are suspect 1 Colorado State Plane Coordinate System — Feet — NAD83(2011NRS) Datum LRM 20220128_revlgw_report tg 11 January 2022 TELESTO as the measured water levels are quite different than simulated. This could be due to the method of surveying ground surface (i.e., general topography instead of point survey at the well location). To evaluate these two wells on model results, we removed their values from the statistics (shown in Figure 8). The model statistics are acceptable without including the MW -04 and MW -10 lending confidence to the model's ability to simulate overall groundwater conditions. Figure 9 is a contour plot of the simulated groundwater elevations representative of the spring season. Comparison of Figures 4 and 9 shows good correlation between model simulated groundwater elevations and flow directions and those measured in the field. 4.3 Parameter/Boundary Sensitivity A sensitivity analysis examines how changing variables within their acceptable range affects the calibration results. Because the model domain contains so many internal boundaries (i.e., Big Thompson River, irrigation ditches, ponds to the south), the model is relatively insensitive to hydraulic parameters. It is very sensitive to the physical construct of the internal boundaries. For example, changing the elevation of the bottom of the ditch near the nearby wells has a direct correlation to the simulated water elevation in the well. Because the physical nature of the internal boundaries are limited by topography, the model sensitivity is less critical. 4.4 Discussion The statistics and plot shown in Figures 8 and 9 indicate that the model successfully mimicked groundwater elevation distributions near the Site for the existing conditions. Visual examination of the scatter around the best fit line, calculated best fit line slope of nearly 1.0, and intercept bordering zero indicates that the model has acceptable bias in the groundwater level predictions and the groundwater flow direction. 5.0 MODEL PREDICTIONS The previous four sections of this report describe the building of the numerical model to provide a base upon which to evaluate potential impacts from LRM's proposed operations. LRM 20220128_revlgw_report tg 12 January 2022 TELESTO The good calibration provides a high level of comfort that the model can accurately identify problematic areas that might produce impacts from the operational scenarios. The overall mine plan related to groundwater is to excavate the pits in a sequential fashion, in roughly 5 -acre increments. LRM will construct an outlet weir on Cell 1 to control the surface water elevation of the resulting lake at elevation 4,737.5 feet. There are no other groundwater controls planned for the cells as LRM will excavate them sub-aqueously (i.e., no dewatering) with no lining. Cells 2 and 3 will connect via an underground pipe to maintain water levels in the completed cells at roughly 4,735 feet elevation. The depths of the four neighboring wells are 32, 45, 56, and 100 feet (shown in Figure 4 as Dunn, Wagner, Wagner 2, and Nelson, respectively). Thus, for the purposes of describing modeling predictions, we considered predicted drawdowns greater than 10% of the well depth as a well needing monitoring for potential impacts. Similarly, we considered a mound (shown as negative value contours on the figures) of two feet or more to indicate areas where a potential may exist for increases in groundwater levels that could pose an issue to homes with basements. The standard deviation of the model residuals is 1.2 feet, thus, the drawdown of 10% of the well depth and two feet mounding are within the model's predictive capacity. 5.1 Mining Plan —Mining Figures 10, through 13 display predicted groundwater elevation and drawdowns at select phases of the mining process. The names of the mining phase match those in Exhibit F of the DRMS mining application. The figures show that subaqueous mining and no lining of the cells tends to flatten the water table near the cell. The maximum drawdown occurs on the upgradient side of the mined cells, with a maximum "mound" at the downgradient end. A predicted drawdown of over 1.2 feet or a predicted mounding of 1.2 feet is considered more than model error. LRM 20220128_revlgw_report tg 13 January 2022 TELESTO 5.2 Mine Plan —Reclamation Figure 15 shows the model -predicted drawdowns after reclamation is complete. Off -site drawdowns near the Dunn well is approaching the 10% monitoring threshold, while mounding is not significant at any off -site location. 5.3 Results Discussion 5.3.1 Drawdown/Mounding Figure 16 summarizes the anticipated changes in groundwater levels associated with neighboring wells. Nelson shows approximately two feet of drawdown well within a range that will not negatively change their ability to withdraw irrigation water from the well. The two Wagner wells will likely experience around a foot of mounding, affecting their wells in a positive manner. The largest potential impact shown is to the Dunn well, where it approaches the 10% of well depth criteria. Drawdown is only one component of a well's ability to extract water. The lakes in Cell 2 and Cell 3 will effectively enhance the production of the well by developing a constant groundwater level nearer to the well. Thus, for the same amount of pumping, the required drawdown in the well will be much less and the well will operate more efficiently. 5.3.2 Water Quality The source of uranium and manganese in groundwater (Appendix B) is likely the underlying Pierre Shale formation. Multiple studies and reports (Sares, 2000; Tourtelot, 1955; Tourtelot, 1962; Carpenter, et al., 1978; Carpenter, et al., 1978) on this phenomena report low levels of both constituents in the sediments, mainly in the form of sulfide (i.e., minerals in reduced forms). They can become even higher concentrations when exposed to the atmosphere and oxygen. One of the large benefits to the sub -aqueous mining proposed for the Dunn Pit is that bedrock will always be under water, reducing even further the chance of exposing the bedrock to oxygen. LRM 20220128_revlgw_report tg 14 January 2022 TELESTO 5.4 Discussion 5.4.1 Model Stability The model converged to a solution during every iteration for the calibration and predictive scenarios, meeting the minimum error criteria in the heads of 0.001 foot. No other significant errors were reported in the model runs. These statistics provide confidence that the model runs were numerically accurate and that the results are numerically sound. 5.4.2 Predictive Results Based on the good correlation and numerical stability of the model, confidence can be placed in the predictive results. The predictions provide a good indicator of areas that will require special attention as mining progresses and gives the opportunity for LRM and neighbors to be pro -active. 6.0 MONITORING PLAN Telesto completed this modeling effort prior to mining. It is calibrated to the spring/early summer timeframe. As time goes by and we collect more data, Telesto will evaluate the model assumptions, and if necessary, update the model for differing conditions. The updated model will provide more accurate predictions and therefore will provide more confidence in the predictive results. The model can be used as a tool to evaluate water supply and other groundwater related issues during operations. The model, however, is only as good as the data on which it is based. Thus, ongoing monitoring of the groundwater is essential. 6.1 Monitoring Plan The mining plan for the Pit assumes a thirty-year mine life. LRM has initiated a pre -mining groundwater monitoring program. The monitoring program consists of monthly depth to ground water measurements of the 10 on -site monitoring wells. Depth monitoring of on - site monitoring wells will shift to quarterly schedule after LRM collects one -years' worth of data are collected and until active operations are completed. LRM 20220128_revlgw_report tg 15 January 2022 TELESTO LRM initiated quarterly water quality sampling from all wells (Appendix B). After LRM obtains one year's worth of quarterly data, we will evaluate the necessity of collecting water quality from all wells on a quarterly basis and propose a modified plan, with justification, to DRMS. 6.1.1 Monitoring Locations To facilitate monitoring groundwater immediately adjacent to the Site, LRM constructed 10 new monitoring wells on the Site properties in May 2021 under State Engineering Office approved monitoring well permits. Monitoring well locations are shown in Figure 4 and well construction permits are included in Appendix A. 6.1.2 Purpose of Monitoring Locations The proposed monitoring locations can be easily accessed by LRM to provide real-time groundwater elevation data. These monitoring locations are intended to provide baseline data representative of pre -mining groundwater levels for the area. Once mining commences, the monitoring locations will capture potential impacts, and provide a base upon which we can review, and update model predicted impacts. 6.1.3 Potential Impacts from Mining Operations As described previously, we do not anticipate large drawdowns or mounding from this project due the sub -aqueous mining approach. We anticipate the largest drawdowns and mounding will occur at the up and down -gradient ends of the pit, respectively. Water quality impacts from exposing the Pierre shale are highly unlikely in LRM's dewatered operations, and improbable under the sub -aqueous mining method. 6.1.4 Water Quality We do not expect mining to impact groundwater quality as previously discussed. However, LRM commits monitoring for metals in groundwater, plus oil sheens in the mined cells. These are the typical sector -specific benchmarks tested in CDPHS discharge permits for sand and gravel pits and batch plants. The water quality monitoring plan is attached as Appendix D. LRM 20220128_revlgw_report tg 16 January 2022 TELESTO 6.1.5 Proposed Trigger Levels and Corrective Actions LRM proposes use of a five-foot drawdown in on -site monitoring wells as a trigger that would initiate more intensive monitoring and discussions of potential mitigation measures with neighbors. If required, LRM will negotiate in good faith to implement corrective actions that are amenable all parties. Corrective actions could include: 1) providing extra augmentation water and supplying water from the mined cells, 2) deepening wells (there is typically an extra 10 feet to bedrock in most domestic wells surveyed) to ensure there is still adequate saturated thickness from which groundwater can be extracted, and 3) re- introducing pumped groundwater through a leach field or injection well back into the aquifer near the impacted well. 7.0 CONCLUSIONS In addition to the objectives summarized in this section, this study describes just a few of the potential mitigation measures available and emphasizes the collaborative strategies that LRM would implement toward neighbors if needed. LRM will work with neighbors to ensure that they have access to and are able to interpret the well monitoring results available on the DRMS website and will continue to collaborate directly with individual landowners as requested. LRM is committed to maintaining communication with neighbors and has taken steps to share the results of this study with adjacent well owners as practical. The modeling efforts met the objectives as outlined in Section 1.2 as follows: • The conceptual model described in detail the groundwater system associated with LRM's Site • The numerical model mimicked existing conditions and then was used to predict impacts. It showed: Changes in groundwater elevations affecting known well users, and provided maps of zones of potential drawdown impacts • Potential mitigation strategies were discussed and evaluated and a plan to monitor and implement corrective actions was provided. As with all models, this model is a numerical representation of the physical system that mimics trends and magnitudes of physical values. While great effort is taken to ensure the LRM 20220128_revlgw_report tg 17 January 2022 TELESTO most accurate representation of the groundwater system, there are still uncertainties resulting from the required assumptions used during the modeling effort. Thus, the model is most useful in identifying areas of potential concern so that management plans can be made to mitigate any potential issues. Again, these areas are where groundwater is predicted to drawdown more than 10% of a neighbors' well depth, or mound higher than 2 feet. 8.0 REFERENCES Blue Marble Geographics, 2015.

The mined material will be Big Thompson River alluvium. LRM retained Telesto Solutions, Inc. (Telesto) to provide oversight for drilling and installing 10 monitoring wells throughout the Site. This drilling summary report presents the drilling, well construction, sampling, and data collection from the 10 monitoring wells installed on Site. The Colorado Division of Reclamation and Mining Safety (DMRS) requires a full year of quarterly groundwater quality and elevation monitoring data prior to the start of mining operations to establish a baseline. The water quality data is analyzed and compared to the Water Quality Control Commission (WQCC) Regulation 41: Basic Standards for Groundwater [i.e., Regulation 41 Standards, (WQCC, 2016)]. Water level data and associated analyses is collected to ensure the hydrologic balance is maintained during and after mining. Thus, Telesto installed the monitoring wells to meet the DRMS requirements. The groundwater monitoring plan (GWMP) consists of installing groundwater monitoring wells, sampling formational materials for potential source identification, and ongoing groundwater quality and level measurements. 1.1 Site Conditions The Site is located within the Northeast 1/4 of Section 3, Township 4 North, Range 67 West of the Sixth Principal Meridian, Weld County, Colorado. The furthermost northwest portion of the site is within the SE 1/4 of Section 34. Township 5 North, Range 67 West of the Sixth Principal Meridian. The site lies south of the Union Pacific Railroad Easement (Figure 1). The topography is generally flat with rolling areas. The surface drainage is parallel with the Big Thompson River in a southeasterly direction. The parcel of land is divided by the Big Thompson River. LRM completed a geotechnical/subsoil investigation on the Site in 1978 (Attachment 1). The purpose of the investigation was to determine the extent and quality of the gravel aggregates found on the Site. Loveland Ready -Mix Concrete 20210909_dunnp it_dri llingswnnaryrep ort. docx July 2021 TELESTO Currently, there are four (three active, one plugged and abandoned) oil and gas wells on the Site, owned and operated by Kerr McGee Oil & Gas Onshore LP. An associated separator and tank battery is also located on the property. According to the Colorado Division of Water Resources' (CDWR's) well permit database, there is 1 permitted water wells on Site and eight permitted water wells located within t/2 mile. 1.1.1 Subsurface Material The subsurface materials encountered during drilling are fairly uniform throughout the Site. They consist of a sandy clay topsoil ranging up to a depth of 4 feet with an average thickness of 2 feet. Beneath the layer of topsoil, clayey sand and gravel was encountered from 6 -inches to 10 feet BGS. Below this layer, intermittent layers of clean sand, pebbles, gravels and cobbles were encountered ranging in depths from 6" to 32 feet BGS. The size of the gravel/cobbles ranged from 1 inch to 4 inches. Beneath the sand and gravel was a weathered claystone/shale which overlaid a harder claystone/shale bedrock. The depth to bedrock ranged from 23.5 feet to 33 feet. 2.0 DRILLING Prior to drilling, Telesto submitted notice of intent to drill form GWS-51, in accordance with Water Well Construction Rules, 2 CCR-402-2 Rule 6.3 with the Colorado State Engineer's Office (Attachment 2). Authentic Drilling Company (License #: 1510) drilled and installed all 10 monitoring wells on Site. The drilling activities occurred from May 4th, to May 7th, 2021. All boreholes were advanced using a hollow stem auger methodology. The drilling depths ranged from 25 feet to 34 feet below ground surface (BGS). Table 1 below summaries the drilling locations, total depth and depth to groundwater.

All borehole geologic logs and well construction logs are presented in Attachment 3. While drilling the boreholes for the monitoring wells, Telesto collected sediment samples from the alluvium and underlying bedrock for each borehole. The samples were prepared and sent to Analytical Laboratory Services —Fort Collins, Colorado (ALS) to analyze selected samples for the Environmental Protection Agency's Synthetic Precipitation Leaching Procedure (SPLP) and whole -rock chemical analysis. 2.2 Well Construction Telesto submitted monitoring/observation water well permits (CDWR Form GWS-46), which included lithology logs and well construction reports (GWS-31), to the CDWR (Attachment 4). The following well completion design was used for all the monitoring wells: • Boreholes advanced using a hollow stem auger methodology • Backfill hole below bedrock to 1' above alluvium -bedrock contact with silica sand Loveland Ready -Mix Concrete 20210909_dunnp it_dri llingswnnaryrep ort. docx 3 July 2021 TELESTO • Two-inch diameter schedule 40 PVC casing • Two-inch diameter 0.01 slot PVC well screen throughout the entire alluvium gravel deposit (20 to 35 feet) to approximately 1 -foot above the water table • 10/20 Silica Sand used a filter pack from the bottom of well to two -feet above the screened interval • Bentonite chips, grout or neat cement added above filter pack to ground surface • Two -foot by two -foot concrete pad and well monument installed at the ground surface • Three foot steel protective stickup surface completion set 2.3 Well Development All monitoring wells were developed following well completion. The wells were purged long enough to remove as much excess sediment as possible from the groundwater and allow for the collection of an accurate representative groundwater sample.

Project Director AFU:mf SCOPE This report presents the results of a gravel resource evaluation prepared for the parcel of land as shown on Exhibit No. 1. The objective of this investi- gation was to determine the extent and quality of the gravel aggregates found on the site. Data gathered through field and laboratory work are summarized in Exhibit Nos. 1 through 7. FIELD INVESTIGATION The field investigation included both test borings and aggregate sampling from caisson holes. The test borings were made between the sixth and eighth of March, 1978 at the locations shown on Exhibit No. 1. The thirty-seven test borings were made with a CME - Model 55 mounted with a four -inch continuous flight auger. As each boring proceeded, a log was kept on which was recorded such information as a description of materials encountered, their respective depths, depth to the groundwater table and any other pertinent data. These logs are reproduced in Exhibit No. 2. The caisson holes were made on the 20, 21, 24 and 25 of April, 1978 at the locations shown on Exhibit No. 1. The four holes were drilled with a 30 - inch power auger to the approximate depth of the water table and the remaining depth of the hole with a 30 -inch diameter mud bucket. Samples of aggregate were taken at various depths throughout the depths of the hole for use in laboratory tests. SITE CONDITIONS .The site under investigation is located in the Northeast Quarter of Section 3, Township 4 North, Range 67 West and lies south of the Union Pacific Railroad (refer to Exhibit No. 1). Presently the site is being utilized as a pasture for cattle and horses. The topography is generally flat with some rolling areas. The surface drainage is in a southeasterly direction. The parcel of land is divided by the Big Thompson River. GROUNDWATER Groundwater was encountered throughout the site as evidenced by the boring logs. The average depth to groundwater from all the test borings was 5.9 -feet. The average elevation of the water table as determined from the boring logs was 4,735. SUBSURFACE MATERIALS The field investigation and laboratory tests for this site indicate the materials encountered are fairly uniform over the area. They consist of a layer of topsoil ranging up to a depth of three feet with an average thick- ness of slightly over 11 inches. Beneath this layer of topsoil, silty or clayey sand and gravel was recorded from one-half foot to ten and a half feet below the surface with an average thickness of this layer being approx- imately four feet. Below this layer, intermittent layers of clean sand, gravel and cobbles were encountered ranging in depth from eight to 31 feet with a total average thickness of 22 feet. A firm clay was then encountered which overlaid a hard claystone bedrock. LABORATORY INVESTIGATIONS The intent of the laboratory investigations was to determine the proportions of sand and gravel at the site and their respective qualities as they relate to construction material standards. The materials used in the laboratory tests were. obtained from the caisson holes and taken from depths which re- flected approximate changes in the various layers of materials. The five tests which were conducted on the aggregate samples with their accompanying ASTM designation are: (1) Sieve Analysis of Fine and Coarse Aggregate, ASTM C 136-76; (2) Specific Gravity and Absorption of Coarse and Fine Aggregate, ASTM C 127-77 and ASTM C 128-73; (3) Soundness of Aggregates by Use of Magnesium Sulfate, ASTM C88-76; (4) Abrasion Resistance of Large and Small Coarse Aggregate by Use of the Los Angeles Machine, ASTM C 535-69 (1975) and ASTM C 131-76, and (5) the Potential Reactivity of Aggregates by the Chemical Method, ASTM C 289-71 (1976). The objective of the sieve analysis is to determine the particle size dis- tribution of fine and coarse aggregates by screening a weighed sample of dry aggregate through a series of sieves of progressively smaller openings. From this information the percentages of material retained on each sieve can be calculated on the basis of total sample weight. The purpose of the specific gravity test is to determine the ratio of ag- gregate weight to the weight of an equal volume of water. It should be noted that specific gravity is not a measure of aggregate quality but rather necessary in certain, design and control calculations. The basic procedure for determining aggregate specific gravity is to take the ratio of the aggregate sample's saturated surface - dry weight to its weight in water. The absorption test determines the quantity of water that a given amount of aggregate will absorb when submerged. It is found by taking the dif- ference between a sample's saturated surface - dry weight and its oven -dry weight as a percentage. The soundness test provides an indication as to structural weaknesses which may be present in an aggregate. It is used to measure the potential freeze - thaw resistance of the aggregate by subjecting it to several cycles of immersion in magnesium sulfate after which the sample is oven -dried. Salt Crystal growth within the aggregate's pores is used to simulate the pres- sures exerted on the aggregate when water freezes and expands within the pores. The soundness is obtained by finding the percentage weight loss of the aggregate after five cycles. The Los Angeles Abrasion Test provides important information concerning the toughness and hardness of an aggregate. It can be used in estimating the breakdown that will occur when aggregates are handled, stockpiled and trans- ported. The basic test calls for putting an aggregate sample into a steel drum with an abrasive charge (12 steel spheres). The drum is then rotated a certain number of revolutions after which the percentage of material worn away during the test is determined. The final test considered within this report is the potential chemical re- activity. Aggregates with certain chemical constituents will react with the alkalies in Portland cement to cause abnormal expansion and hair -line crack- ing of the concrete. Potentially reactive siliceous aggregates are identi- fied by their degree of reaction with a sodium hydroxide solution. AGGREGATE QUANTITIES A topographical survey was made of the subject site by means of aerial photo- graphy. The purpose of this survey was to obtain existing ground elevations in order to plot cross sections for quantity calculations. By using these cross sections and through interpolation of the Test Hole Logs, the total amount of coarse and fine aggregate was found to be in the'order of 2.8 million cubic yards. Of this total approximately 1.25 million cubic yards is coarse aggregate. It should be pointed out that these numbers are approximate and more extensive drilling would have to be performed in order to achieve more accuracy. The aggregate size distribution has been tabulated on Exhibit No. 3. LIMITATIONS Test Borings for this investigation were spaced to obtain a reasonably accurate representation of subsurface conditions. Variations from the conditions disclosed which were not indicated by the test explorations frequently occur and quite often these variations are sufficient to neces- sitate additional testing. The judgements and results in this report are based upon our evaluation of actual physical conditions encountered at the location indicated herein, and upon our extrapolations thereof. We do not warrant the accuracy of such extrapolations beyond the limits of the tests performed or where actual physical conditions were not observed. Under the above conditions, it is important that we inspect the subsurface materials exposed in excavations to take advantage of all opportunities to recognize differing conditions and minizing the risk of having undetected conditions which would affect the performance of the facility. Should you have any questions or are in need of further information re- garding this report, please feel free to contact us. Respectfully, C -E MAGUIRE, INC.

(Telesto) oversight in May of 2021 to provide robust hydraulic conductivity data for the aggregate resource (alluvium) for the site. Objective : The main objective of the short-term aquifer testing program was to obtain reasonable estimates of the hydraulic conductivity of the alluvium at the Proposed Dunn Pit. Given this objective, several simplifying assumptions were used in analyzing the aquifer test data: Assumptions and Approach : 1. Groundwater flow to the wells is horizontal and vertical components of flow are negligible 2. The bottom of the well screen represents the bottom of the aquifer 3. Flow to the well is radial and the aquifer is of "seemingly" infinite lateral extent 4. The aquifer is homogeneous and isotropic 5. The drainable porosity of the well sandpack material is 0.25 6. Due to water table drawdown near the well, the appropriate aquifer thickness is given by: b = hw + hi12 where: b = The representative aquifer thickness hw = The height of water in the well at the end of the test h; = The initial height of water in the well. Analysis: Based on the assumptions above, Telesto used methods to analyze aquifer tests that were based, on the Theis solution of radial flow to a well in an infinite aquifer: s = Q/4rrT * W(u) (1) where: s = drawdown at an observation point (L) Q = pumping rate of the well (L3/T) T = aquifer transmissivity (L2/T) W(u) = Theis well function u = variable defined by: u = r2S/4Tt where: r = radius of interest (L) S = storage coefficient of the aquifer t = time (T) (2) TELESTO 5 O L U T I O N 5• I r, C n K p .

Thus, if drawdown (s) data are plotted against log time (t) on semi -log paper, and the pumping test has been performed for an adequate amount of time, the data should approximate a straight line. Through either a linear regression analysis or visual fitting of a straight line to this data, the aquifer transmissivity can then be calculated from the following equation: where: 2.303 Q T- 4TcOs As is the change in drawdown over 1 log cycle of time. (5) By definition, the transmissivity is a product of the aquifer thickness (b) and the hydraulic conductivity (K). Thus, the hydraulic conductivity can be estimated by: _T K b (6) McWhorter and Sunada (1977) describe this procedure, called the Jacob method, in more detail. This type of analysis was applicable to the 2 tests performed at Dunn Pit . Figures 1 and 2 and Table 1 display the semi -log plots and results of this method used on the Dunn Pit wells.

Assumptions 2 and 3 are appropriate due to the short-term nature of the aquifer tests performed at the Proposed Dunn Site. Assumption 5 is based on porosity values cited in the literature for a clean sand (McWhorter and Sunada [1977], Freeze and Cherry [1979], and Spitz and Moreno [1996]). Assumption 6 is based on the Dupuit-Forcheimer assumption and is explained in McWhorter and Sunada (1977). Conclusions: The calculation set achieved the objectives set forth through robust use of the available data and design information. The short-term aquifer tests provided a quick and acceptably accurate method to gain insight into hydraulic properties of the alluvium at the Dunn Pit. These properties can be used to estimate groundwater flow in the groundwater model for the Proposed Dunn Pit. References: Freeze, R. Allan and John A. Cherry. 1979. Groundwater. Prentice Hall, Inc.

January 2022 — Rev I 1.0 INTRODUCTION In September 2021, Loveland Ready Mix (LRM) submitted an application to the Colorado Division of Reclamation Mining and Safety (DRMS) to permit the proposed Dunn Pit. As part of the approval process the Division requires LRM submit a groundwater quality monitoring plan and sufficient data to determine baseline groundwater quality and demonstrate the site will be in compliance with CDPHE Water Quality Control Commission (WQCC) Regulation 41: Basic Standards for Groundwater during the tenure of the mine and reclamation. This Sampling and Analysis Plan (SAP) describes the sampling and analysis methods and monitoring schedule that will be employed for the collection of groundwater quality samples at the Dunn Pit (Site). The site and monitoring well locations are shown in Figure 1. Groundwater elevation contours for the area are also included in Figure 1. 2.0 OBJECTIVE The objective of this SAP is to characterize baseline groundwater quality in the aquifer underlying the proposed Site (Big Thompson Alluvial Aquifer), ensure mining and reclamation activities at the Site do not degrade existing groundwater quality/uses and that the water quality collection methods guarantee data quality. The SAP includes: • Collection of ground water samples • Collection of ground water quality data • Documentation of data collection activities • Analytical methods and detection levels • Sampling protocols • Quality Assurance and Quality Control (QA/QC) 3.0 STANDARD OPERATING PROCEDURES Standard Operating Procedures (SOPs) for activities performed during this investigation are included in Attachment 1. These SOPs include: Loveland Ready -Mix Concrete, Inc. appd_30330138_updated_Inn_dunngw_sap_rev1 1 Telesto Solutions, Inc. January 2022 — Rev I • SOP #1 Equipment Decontamination • SOP #2 Monitoring Well Water Level Measurement • SOP #5 Ground Water Sample Collection • SOP #7 Sample Documentation, Handling, Packaging, and Chain of Custody • SOP #9 Field Parameter Instrument Calibration and Measurement 4.0 DECONTAMINATION PROCEDURES The overall objective of ground water sampling programs is to obtain water samples that accurately depict the chemical and/or physical conditions at a site. Extraneous materials can contaminate water samples during a sampling program. While well development and purging procedures may help to remove contaminants, these procedures may not be completely adequate, therefore laboratory test results of the collected water samples maybe inaccurate due to outside contamination. General decontamination procedures are presented in SOP #1. All equipment that will contact sampled media will be decontaminated. General procedures that apply to decontamination are listed below. • Dress in suitable safety equipment to reduce personal exposure. • Wear clean or new rubber or nitrile gloves during decontamination activities and when handling decontaminated equipment. • Use new equipment, such as disposable filters and silicon tubing that is certified clean by the manufacturer. • Decontaminate all wash/rinse tubs before initial use. • Replace rinse and detergent waters, unless in garden sprayers, with new solutions between sample locations. In some cases, new solutions may be needed between samples in the same location. • Following decontamination, place equipment in a clean area or on clean plastic sheeting to prevent contact with contaminated soil. If the equipment will not be used immediately, cover the equipment or wrap it in plastic sheeting or heavy duty trash bags to minimize potential airborne contamination. 5.0 GROUND WATER SAMPLE COLLECTION Ground water samples will be collected from the selected monitoring well locations identified on Figure 1 and listed in Table 1. Initially, ground water samples were collected from all monitoring wells to monitor overall background ground water quality. Attachment 2 includes the completed ground water data sheet for each monitoring well sampled. The Loveland Ready -Mix Concrete, Inc. appd_30330138_updated_Inn_dunngw_sap_rev1 2 Telesto Solutions, Inc. January 2022 — Rev I five monitoring wells shown in Figure 1 will be sampling locations for future ground water samples to establish baseline ground water data . Well completion logs for all monitoring well are included in the well monitoring report (Appendix A of the Groundwater Baseline Report). All ground water sampling equipment which will contact the ground water sample will either be decontaminated following the procedures specified in SOP #1 or be new and certified clean by the manufacturer. Prior to sample collection, sampler will collect a water well level measurement per the procedures outlined in SOP #2. Depending on the monitoring well characteristics, a minimum of three casing volumes will be purged from each well. Field water quality parameters will be measured during purging, and purging will continue until the parameters have stabilized. In instances where it may not be practical to purge three casing volumes, field water quality parameters will be monitored for stability before the three casing volumes are purged. In general, the monitoring wells listed in Table 1 are expected to yield sufficient water to allow for three casing volumes before sampling. Once field parameters have stabilized and or three well volumes have been removed, groundwater samples will be collected. Well purging, monitoring of field parameters and sample collection will be performed in accordance with the SOPs listed above. Field analytical parameters (which include pH, specific conductivity, temperature) and groundwater quality parameters to be analyzed are listed in Table 2. 6.0 SAMPLE DOCUMENTATION, HANDLING, PACKAGING, AND CHAIN OF CUSTODY The standard operating procedures for sample documentation, handling, packaging, and chain of custody are presented in SOP #7. Sample custody procedures are to be followed to ensure that sample integrity is maintained during collection, transportation, and storage prior to analysis. A minimum number of individuals will handle the samples. The field sampler is personally responsible for collection and custody of the samples until they are transferred to the lab. Loveland Ready -Mix Concrete, Inc. appd_30330138_updated_Inn_dunngw_sap_rev1 3 Telesto Solutions, Inc. January 2022 — Rev I 7.0 FIELD QUALITY ASSURANCE AND QUALITY CONTROL PROCEDURES 7.1 Field Parameter Instrument Calibration and Measurement Field parameter instruments and calibration/measurement procedures are presented in SOP #9. Ground water field parameters include pH, conductivity and temperature. Field parameter instruments will be calibrated before initial measurements and as needed throughout the day as required to maintain instrument accuracy. 7.2 Field Quality Assurance/Quality Control Samples The primary sample and field quality control samples are listed in Table 2. Quality control samples will include field duplicates, field blanks and rinsate samples. QA/QC samples help identify potential sources of sample contamination and help evaluate potential error introduced by sample collection and handling. All QA/QC samples will be labeled with QA/QC identification numbers (i.e., "02" for duplicate samples, "03" for field blanks, "04" for rinsate) and sent to the laboratory with the other samples for analyses. 7.2.1 Duplicate Samples Duplicate samples are collected to check for the natural sample variance and the consistency of field techniques and laboratory analysis. Duplicate samples are collected side -by -side with primary samples. For groundwater sampling, a duplicate sample will be collected when collecting the primary sample. Primary sample bottles will be collected first and then the duplicate sample bottles for the same analysis will be collected until all necessary sample bottles for both the primary and duplicate samples are filled. Different filter and tubing will be used for the primary and duplicate samples. The duplicate water sample will be handled in the same manner and analyzed for the same parameters as the primary sample. The duplicate sample will be assigned the QA/QC identification number "02," stored in an iced cooler, and shipped promptly to the laboratory so that analyses can be performed within required holding times. One duplicate sample will be collected per sampling episode. Loveland Ready -Mix Concrete, Inc. appd_30330138_updated_Inn_dunngw_sap_rev1 4 Telesto Solutions, Inc. January 2022 — Rev I 7.2.2 Field Blanks Field blanks will be collected by filling sample containers in the field with deionized water. The sample will be assigned the QA/QC identification number "03," stored in an iced cooler, and shipped to the laboratory with the other samples. One field blank will be collected per sampling event. 7.2.3 Rinsate Samples An equipment rinsate sample of sampling equipment will be collected to check if decontamination procedures have been effective. For the well sampling operation, a rinsate sample will be collected from the decontaminated sampling equipment (bailer or pump) and filter equipment before using it to obtain the sample. A rinsate sample will be collected for ground water sampling by transferring the final deionized water rinse that is pumped through the discharge hose into sample bottles. The same parameters that will be analyzed in the ground will be analyzed in the rinsate samples. The rinsate sample will be assigned the QA/QC sample identification number "04," stored it in an iced cooler, and shipped promptly to the laboratory so that analyses can be performed within the holding times. One rinsate sample will be collected per sampling event. If disposal bailers or sampling equipment is used during sampling events, rinsate samples will not be collected. 7.3 Laboratory Quality Assurance/Quality Control 7.3.1 Matrix Spike Samples Matrix spike (MS) samples will be analyzed to evaluate potential matrix effects on sample analyses for all inorganic parameters. The laboratory will analyze matrix spike samples for the inorganic parameters. The matrix spike samples will be split from an existing sample by the laboratory. 7.3.2 Laboratory Replicate Laboratory replicate samples will be split from the primary sample in the laboratory and analyzed as part of the laboratory's QA/QC program. The laboratory replicate will not require a separate sample volume. Loveland Ready -Mix Concrete, Inc. appd_30330138_updated_Inn_dunngw_sap_rev1 5 Telesto Solutions, Inc. January 2022 — Rev I 8.0 SAMPLING SCHEDULE AND DATA MANAGEMENT Prior to any mining activities exposing groundwater or initiating dewatering operations at the Site, LRM will collect, and submit, quarterly baseline water quality samples for a period of four quarters to confirm the baseline water quality of the underlying aquifer (Big Thompson Alluvial Aquifer). If after four quarters of sampling, water quality data indicates no reportable differences to analyte detection levels, LRM will submit documentation to the Division demonstrating the consistency in water quality results provides rational and compelling evidence sufficient to establish baseline conditions. With document submittal, LRM will request a sample reduction through a submittal of a Technical Revision with the Division approval to begin mining and/or dewatering operations without additional background monitoring. During active mining operations and reclamation, LRM will work with DRMS to develop a meaningful program to continue groundwater monitoring on a regular basis and with an annual report submitted each year. Active mining and reclamation are expected to last 30 - years. Loveland Ready -Mix Concrete, Inc. appd_30330138_updated_Inn_dunngw_sap_rev1 6 Telesto Solutions, Inc.

September, 2009 1 Equipment Decontamination Standard Operating Procedure No. I 1.0 PURPOSE AND SCOPE The purpose of this document is to define the standard procedure for decontamination. The American Society for Testing and Materials (ASTM) Standard Practice for Decontamination of Field Equipment Used at Nonradioactive Waste Sites (D 5088-90) was used as a guide in preparing this Standard Operating Procedure (SOP). The overall objective of multimedia sampling programs is to obtain samples that accurately depict the chemical, physical, and/or biological conditions at the sampling site. Extraneous contaminants can be brought onto the sampling location and/or be introduced into the medium of interest during the sampling program (e.g., by bailing or pumping ground water with equipment that was previously contaminated at another site). Trace quantities of these contaminants can thus infect a sample and lead to false positive analytical results and, ultimately, to an incorrect assessment of the contaminant conditions at the site. Decontamination of sampling equipment (e.g., bailers, pumps, tubing, and soil and sediment sampling equipment) and field support equipment (e.g., drill rigs and vehicles) is therefore required to ensure that sampling cross - contamination is prevented and that on -site contaminants are not carried off -site. 2.0 RELATED STANDARD OPERATING PROCEDURES This procedure is intended to be used with the following SOP: SOP # Title 7 Sample Documentation, Handling, Packaging, and Chain of Custody 3.0 EQUIPMENT NECESSARY FOR DECONTAMINATION The following equipment may be needed to perform decontamination: Telesto Solutions, Inc. September, 2009 1 Equipment Decontamination Standard Operating Procedure No. I • Brushes • Wash tubs (plastic) • Buckets (plastic) • Scrapers • Steam cleaner or hot water washer • Paper towels • Liquinox detergent (or equivalent) • Potable water • Deionized water • Garden type water sprayers • Laboratory wash bottles • Clean plastic sheeting and/or trash bags. 4.0 DECONTAMINATION PROCEDURES 4.1 General Decontamination Procedures for All Equipment Decontaminate all equipment that will contact a sampled media. General procedures that apply to most specific decontamination procedures are listed below. • Dress in suitable safety equipment to reduce personal exposure. • Wear clean or new rubber or latex gloves during decontamination activities and when handling decontaminated equipment. • Do not decontaminate new equipment, such as disposable filters and silicon tubing, that is certified clean by the manufacturer. Telesto Solutions, Inc. September, 2009 2 Equipment Decontamination Standard Operating Procedure No. I • Decontaminate all wash/rinse tubs before intial use and between boreholes. • Replace rinse and detergent waters, unless in garden sprayers, with new solutions between borings or sample locations. In some cases, new solutions may be needed between samples in the same location. • Following decontamination, place equipment in a clean area or on clean plastic sheeting to prevent contact with contaminated soil. If the equipment will not be used immediately, cover the equipment or wrap it in plastic sheeting or heavy duty trash bags to minimize potential airborne contamination. 4.2 Decontaminating Sampling Equipment Decontaminate sampling equipment as follows: 1. Scrape off gross contamination from equipment at the sampling or construction site. 2. For equipment that water will not damage, place the equipment in a wash tub containing Liquinox and potable water or spray the equipment with a Liquinox/potable water solution contained within a garden type sprayer, and scrub the equipment with a bristle brush or similar utensil (if possible). 3. In a second wash tub or using a second garden sprayer, triple rinse equipment with potable water to remove the Liquinox solution. 4. Triple rinse the equipment with deionized water from a garden sprayer laboratory wash bottles, and let the equipment air dry (if possible). 4.3 Decontaminating Submersible Pumps Decontaminate the insides of an electric submersible pump and discharge hose (e.g., a Redi-Flo 2 pump) as follows: or 1. Before performing internal decontamination, remove the Redi-Flo2 internal pump fluid and replace it with deionized water (see the Red-Flo2 owners manual). 2. Pump Liquinox/potable water solution through the pump and hose. Be sure that the volume of solution used is not less than one volume of fluid contained in the Telesto Solutions, Inc. September, 2009 3 Equipment Decontamination Standard Operating Procedure No. I pump and hose. (Note that a Redi-Flo2 pump with 250 feet of 0.5 -inch inner - diameter hose contains 2.55 gallons of fluid.) 3. Pump potable rinse water through the pump and hose. Be sure that the volume of solution used is not less than three times the volume of fluid contained in the pump and hose. 4. Pump deionized rinse water through the pump and hose. Be sure that the volume of solution used is not less than three times the volume of fluid contained in the pump and hose. Decontaminate the outside of the pump and discharge hose as follows: 1. When removing the pump and hose from the well, place the hose reel 10 to 20 feet away from the well to allow the hose to be decontaminated before placing it on the reel. Do not let decontamination fluids enter the well. 2. While removing the pump from the well, wash the outside of the pump and hose with Liquinox/potable water solution and triple rinse it with potable water. 3. Triple rinse the hose with deionized water before placing the hose on the reel and/or triple rinse the hose with deionized water while lowering the pump into the next well. If the pump and hose are exposed to airborn contaminants (e.g., dust and mud), rinse the pump and hose while lowering the pump down the next well. 4.4 Decontaminating Water Level Probes Decontaminate water level probes by using the general decontamination procedures for sampling equipment (Section 4.2) or by wiping them successively with paper towels wetted with Liquinox solution, potable water, and deionized water. Rinse the water level probe with deionized water before use. Store the water level probe in a plastic bag after decontamination. 4.5 Decontaminating Delicate Equipment Telesto Solutions, Inc. September, 2009 4 Equipment Decontamination Standard Operating Procedure No. I Carefully wipe clean equipment that water will damage successively with paper towels wetted with Liquinox solution, potable water, and deionized water. Be sure to avoid damaging the equipment. 4.6 Decontaminating Drilling and Heavy Equipment Decontaminate drilling and heavy equipment as follows: • Dress in suitable safety equipment to reduce personal exposure. • With a flat -bladed scraper, scrape gross contamination or drill cuttings off equipment at the sampling or construction site. • Spray equipment, such as drill rigs, augers, drill bits, and shovels, with a Liquinox/potable water solution using a hot water washer. Be sure to adequately clean the insides of the hollow -stem augers and backhoe buckets. • Rinse the equipment with potable water. • Place drilling equipment on the clean drill rig and move it to a clean area. If the equipment will not be re -used immediately, store it in a designated clean area. 4.7 Disposing of Decontamination Solution Dispose of used wash and rinse solutions at a location that will not bias subsequent samples. 5.0 DOCUMENTATION Be sure to document the decontamination of sampling and drilling equipment. Record the documentation with black waterproof ink in the sampler's field notebook with consecutively numbered pages. This documentation should include the following: Telesto Solutions, Inc. September, 2009 5 Equipment Decontamination Standard Operating Procedure No. I • The personnel who performed the decontamination • Date • Decontamination procedures and observations • Rinsate sample collection procedure (if collected). 6.0 QUALITY ASSURANCE REQUIREMENTS To verify the effectiveness of the decontamination procedures, collect equipment rinsate samples from the decontaminated sampling equipment as follows: • Run deionized water through or over a representative decontaminated sampling tool (such as a split spoon sampler or bailer) and collect the rinsate water in sample bottles. • Filter, preserve, handle, and analyze rinsate samples for the same parameters as primary samples collected at the site. Refer to SOP #7 for sample documentation, handling, packaging, and chain -of -custody procedures. • Record the rinsate procedure, including the sample number, in the field notebook. • Send the bottles to the laboratory for analysis. Collect equipment rinsate samples at the following frequencies: • If more than 20 field samples were collected, collect one rinsate sample per 20 field samples collected. • If less than 20 field samples were collected in the sampling event, collect at least one rinsate sample per sampling method used. • When using more than one sampling method or type of equipment, collect at least one rinsate sample from each type of device that was used to obtain samples (e.g., if both a bailer and a electric submersible pump were used to collect ground water samples, collect a rinsate sample from both devices at a minimum frequency of 1 each per 20 samples).

This Standard Operating Procedure (SOP) describes equipment and field procedures necessary to collect water level measurements. 2.0 RELATED STANDARD OPERATING PROCEDURES This procedure is intended to be used with the following SOP: SOP # Title 1 Equipment Decontamination 3.0 NECESSARY EQUIPMENT The equipment necessary to measure water levels includes: • Electric water level probe capable of producing measurements to the nearest 0.01 foot • Replacement batteries for water level probe • Field logbook, field data sheets, and black pen • Engineers tape (marked in increments of 10ths and 100ths of a foot) • Additional stainless steel weight • Paper cups and/or turkey baster • Paper towels • Liquinox soap • Potable water • Sprayer filled with deionized water Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a_sop02_wl measure.doc 1 January 20 Monitoring Well Water Level Measurement Standard Operating Procedure # 2 • Appropriate health and safety equipment, including at least safety glasses and latex gloves. 4.0 WATER LEVEL MEASUREMENT PROCEDURES This section gives the sequence of events to follow when measuring water levels. • Before mobilization to the site, obtain the following: previous water level data and survey data if available (data should include description of measurement point location and survey point description) well completion data, including total depth, well casing stickup, and protective casing stickup if wells are locked, obtain the appropriate key. • Wear appropriate health and safety equipment, as described in the Health and Safety Plan when opening and measuring wells and performing decontamination. At a minimum, wear safety glasses and latex gloves. (Latex gloves are required to prevent cross contamination.) • To minimize potential cross contamination, measure the wells in order of cleanest to most contaminated. • Before taking measurements, decontaminate the water level probe according to SOP #1 and Section 5 of this SOP. • Unlock and open the well. If the water level is above the top of the well and cap, evacuate the water with a paper cup or a turkey baster. Follow all health and safety procedures and if necessary, let the well vent any gasses that may be present in the well casing. If you observe either a negative or positive pressure when opening the well, let the well stabilize before measuring the water level. Stabilization could take several minutes, hours, or days, depending on well characteristics. • Test the water level probe to verify that it is working properly. Push the circuit test button to verify that the light/buzzer is working. This button tests only the light/buzzer and does not test the other parts of the water level probe. Dip the tip of the water level probe into water to verify that the water level probe is working properly. Note that deionized water, due to its low conductivity, will not trigger a response. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a_sop02_wl measure.doc 2 January 20 Monitoring Well Water Level Measurement Standard Operating Procedure # 2 • After opening the well cover, locate the measuring point for water level measurements. The measuring point for the water level is usually the top of the well casing, not the protective casing, but it can vary between wells and programs. Some programs will specify on which side of the well casing (i.e., the north side) to locate the measuring point or will specify the highest point of the casing if it is not cut evenly. If not already marked and described, the measuring point should be marked and described for easy identification. If possible, the measuring point should be the same as the survey point. • To measure the static water level, lower the water level probe into the well until the buzzer/light indicates that the probe tip has contacted water. By raising and lowering the water level probe and adjusting the sensitivity to indicate when the probe is contacting the water, the depth to water should be measured to the nearest 0.01 foot. Record the water level depth below the measuring point in the field book or data sheet. Then recheck the measurement before removing the water level probe from the well. Compare the most recent measurement with past measurements and verify that the new measurement is reasonable before leaving the well. If the measurement does not seem reasonable, measure the water level again. • If the well is dry, record the maximum depth measured (e.g., dry to 44.34 feet). • Measuring the total well depth will help identify the well, indicate if there is well damage or accumulated sediment in the well, and provide data to calculate saturated borehole volume prior to purging the well. If water contacts cuts or nicks in the line and causes a "short" in the line, you may need to repair and/or clean and dry the line before reuse. (Note: Because measuring total depth in deep wells with high water levels can force water around seals in tips and may cause shorting, the tip may need to be disassembled and dried.) The total well depth should be measured unless a recent total depth measurement has been fully documented. If the measuring point on the well probe is not at the tip of the probe, adjust the total depth measurement to account for the distance between the water measurement point and the tip of the probe. • When raising or lowering the water level probe from the well, exercise great care to avoid pulling the probe wire over the well casing or the protective casing. Even PVC pipe can damage the water level probe if it is not handled properly. • Especially on deep wells, you may need an additional weight to lower the water level probe to the water level. A non -contaminating, long, narrow weight (e.g., a stainless steel rod) should be used. Tape the weight to the water level probe line with plastic electrical tape only when not measuring organics, and remove the weight prior to decontamination. Excessive weight could damage the water level probe by stretching or even breaking the line. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a_sop02_wl measure.doc 3 January 20 Monitoring Well Water Level Measurement Standard Operating Procedure # 2 • Measure the distance that the protective casing sticks up above ground level and the distance from the measuring point on the top of the well casing to the top of the protective casing. • Wells with submersible pumps or other installed equipment probably should not be measured unless a tube specifically designed for water level measurements is present. The risk of losing the water level probe and/or damaging equipment installed in the well is considerable. Before attempting to measure a water level in a well with any installed equipment, obtain the project manager's approval. 5.0 DECONTAMINATION Decontaminate the water level indicator before measuring the water level in the first well and after measuring the levels in all wells. Decontaminate the probe according to SOP #1. Decontamination requirements will vary depending on the contaminants present and their concentrations, and some sites may require decontamination of the probe between measurements at each well. At mining sites where low-level inorganic background parameters are being monitored, the decontamination procedure may consist of the following: (1) wiping the well probe line, as it is removed from the well, successively with paper towels that have been wetted with Liquinox solution, potable water, and deionized water and (2) rinsing the entire reel with deionized water before use. Although this method is efficient, it may not be acceptable at all sites. Other acceptable decontamination procedures are specified in SOP #1. The decontamination procedure used should be approved by the project manager before use. Once decontaminated, the water level probe should be either placed in a clean plastic bag or used immediately. If the water level probe has contacted especially corrosive fluids (e.g., water with high or low pH values, high chlorides concentrations, or high TDS concentrations), at a minimum, thoroughly rinse the water level probe immediately after use to protect the water level probe from damage. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a_sop02_wl measure.doc 4 January 20 Monitoring Well Water Level Measurement Standard Operating Procedure # 2 6.0 DOCUMENTATION This section describes the documentation necessary for water level monitoring. Record at least the following information in the field book or on the ground water data sheets for each well: • Personnel who performed the measurement • Date • Time • Well number • Depth to water from measurement point • Depth to well bottom from measurement point • Distance from the well probe's water level measurement point to the well probe tip to correct total depth measurements • Distance from top of protective casing to ground surface • Distance from measuring point on top of the well casing to the top of protective casing • Description of the measurement point location • Description of the decontamination procedure • Well probe's identification number • All calculations performed. The field notebook used during water level measurement activities will include any other observations made while measuring water levels. 7.0 CALIBRATION The water level measurement probe cord should be calibrated at least annually or more often as needed to ensure the desired accuracy. The calibration check consists of laying out 100 feet of steel Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a_sop02_wl measure.doc 5 January 20 Monitoring Well Water Level Measurement Standard Operating Procedure # 2 tape next to 100 feet of the probe cord. At 2 -foot intervals, note any measurement discrepancies between the two. The probe cord shall be rechecked if it may have been stretched or damaged during water level measurements.

The amount of water that that needs to be purged and how to determine that the resulting sample will be representative of the formation is a frequently debated issue. The two most common methods are purging a set number of saturated borehole volumes and/or casing volumes, usually between 3 and 10, and demonstrating the stability of field parameters (e.g., pH, conductivity, temperature, and turbidity) over a specified volume. Although this SOP discusses a minimum purge volume and stability of field parameters, the best procedure to help collect a representative sample requires on -site evaluation of all field conditions, which includes purge volume, stabilization of field parameters, well construction, hydrologic properties of the formation, and parameters of interest. Due to the variability of site conditions, no one procedure can ensure that a representative sample will be collected without the possibility of over- or under -purging some wells. 4.2 Calculating Saturated Borehole Volume Monitoring wells should be purged before sampling so that representative ground water is sampled, not the potentially biased water stored in the well casing and filterpack. Because the representativeness of stored water is questionable, stored water should be purged from the monitoring well before collecting samples. Removing all stored water in most cases is not feasible or practical. Therefore, before collecting ground water samples, purge an undetermined amount of water from the monitoring well until representative formation water can be sampled. The amount of water to purge will vary from well to well based on specific well characteristics. No one method of calculating the required purge volume will always work. The usual method to estimate purge volumes is to calculate a number of casing volumes or saturated borehole volumes. Casing volumes account for only the water in the well casing and does not account for the water in Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 6 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 the annular borehole space, which is independent of the casing size. Calculating the saturated borehole volume accounts for all the water within the borehole and casing. If purging procedures were completely efficient, the saturated borehole volume would be the minimum volume of water to purge to remove the potentially biased water from the borehole. Because mixing does occur, the minimum purge volume must be greater than one saturated borehole volume. The degree of mixing within the borehole during purging is difficult to estimate and, therefore, the range of recommended purge volumes varies from 3 to 10 saturated borehole volumes. Three saturated borehole volumes has been selected as the best way to estimate purge volumes. Some wells will require purging more than three saturated borehole volumes and some less. The saturated borehole volume calculation formula is presented in Figure 1. Figure 2 presents a sample saturated borehole volume calculation and a blank form to calculate specific saturated borehole volume. The basic formula is volume equals pi times the radius squared times depth (V=mr2d). To calculate saturated borehole volume, the casing and borehole radii and the height of water in the casing and the filter pack must be known. Measure the water level in the field, and obtain the borehole and casing radii from the well completion data. Figure 2 presents a sample saturated borehole volume calculation, as described below: • Equation (a) shows how to calculate the casing radius in feet by dividing the nominal casing diameter in inches by 2 (to convert the diameter to a radius) and dividing the result by 12 (to convert inches to feet). • Equation (b) shows how to calculate the borehole radius in feet by dividing the nominal borehole diameter in inches by 2 (to convert the diameter to a radius) and dividing the result by 12 (to convert inches to feet). • Equation (c) shows how to calculate the casing volume, given the casing radius and height of water in the casing. • Equation (d) shows how to calculate the annular volume, given the annular radius and the height of water in the filter pack. • Equation (e) shows how to calculate the saturated annulus volume by subtracting the casing volume from the borehole volume and multiplying the result by the assumed effective porosity of the annulus. • Equation (f) shows how to calculate the saturated borehole volume by adding the casing volume to the saturated annulus volume and converting cubic feet to gallons. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 7 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 In confined wells and unconfined wells that are screened and filter packed below the water table, the height of water in the casing will exceed the height of water in the filter pack (i.e., hi>h2). In these cases, calculate the height of water in the filter pack based on the top of the filter pack interval, and not the top of the screen interval. To calculate the saturated borehole volume in these cases, substitute the appropriate height of water in feet into Equations C and D. Note that wells have variable amounts of filter pack below the bottom of the screen. The volume of water below the bottom of the screen may be a significant portion of the total saturated borehole volume if there is only a few feet of measurable water in the screen and several feet of filter pack below the bottom of the screen. The saturated borehole volume calculation presented in Figures 1 and 2 does not account for the volume of water in the borehole below the screen. For wells with only minimal amounts of water in the screen, evaluate the amount of water within the borehole below the screen and consider it when purging the well. 4.3 Stability of Field Parameters To demonstrate that you have collected a representative ground water sample, measure field parameters during purging and purge the well until these parameters stabilize. The field parameters measured may include pH, conductivity, temperature, turbidity, Eh, and dissolved oxygen. However, these parameters tend to stabilize at different rates, and field parameters generally stabilize before the chemical parameters that are being sampled. Therefore, the purge volume required for field parameters to stabilize should be considered a minimum purge volume, and laboratory parameters may stabilize only with continued purging. In order to demonstrate that parameters have stabilized, establish the acceptable range of field parameter values and the volume of water between field parameter measurements. The acceptable range for most field parameter measurements is generally 10 percent of the value for conductivity, temperature, turbidity, Eh, and dissolved oxygen, and 0.1 units for pH. Demonstrate stabilization over a minimum volume of one saturated borehole volume. Document that the measurements do Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 8 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 not fluctuate more than 10 percent or 0.1 pH units between the end points. Collect as many field parameter readings as practical between the end points (i.e., one reading at every 1/4 to 1/2 saturated borehole volume). Calibrate the pH and conductivity meters before use every day. Record calibration times and appropriate readings in the field notebook. Refer to SOP #9 for specific instructions on calibrating the pH and conductivity meters. 4.4 Purge Rates and Pump Placement Do not let the purge rate exceed the development rate. If possible, purge wells at or below their recovery rates in order to minimize turbidity and drawdowns. The purge rate should not result in excessive drawdown. Excessive drawdowns can cause water to cascade into the well, resulting in a significant sample bias, excessive turbidity, and entrapment of air in the filter pack, which will cause long-term sample bias. When purging wells in shallow water tables, locate the pump intake near the top of the water table. Water will enter throughout the screen interval and move toward the pump, flushing all stagnant water from the borehole. If bailers are used, remove the water from the top of the water level. 4.5 Purging Low -Yielding Wells Monitoring wells incapable of yielding three saturated borehole volumes within 24 hours are considered low -yielding wells. Low -yielding wells may be pumped at or below their recovery rates or purged to practical dryness. Purging the well to practical dryness will evacuate the stagnant water in the borehole, but cascading water and exposing the filter pack to air may bias subsequent samples. Preferably, purge low -yielding wells at or below the recovery rate so that the saturated filter pack is not exposed to air. Purging at or below the recovery rate can take a considerable amount of time and may not be practical in some cases. Purge volume requirements and stabilization of field Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 9 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 parameters criteria cannot always be applied to low -yielding wells. However, you should still perform saturated borehole volume calculations and field parameter measurement. Purging low - yielding wells can be time-consuming. Identify low -yielding wells during well development so that careful planning and scheduling may be performed to increase efficiency in the field. Based on site - specific conditions and project objectives, evaluate whether to purge a well over an extended period of time or to purge it to dryness and collect a sample when there is sufficient recovery. Purging over time is preferred over dryness if at all practical. Development should provide enough site - specific information to allow the best method to purge a well to be assessed and to acquire representative samples before mobilizing to the field. 5.0 SAMPLING PROCEDURES This section gives the step-by-step procedures for collecting samples in the field. Record observations made during sample collection in the field notebook and field data sheet, as specified in Section 6 of this SOP. 5.1 Evacuating Well As stated previously, the purpose of well purging is to (1) remove stagnant water from the well and (2) obtain representative water samples from the geologic formation while minimizing disturbance to the collected samples. In most cases, purge the well three saturated borehole volumes and until field parameters stabilize. If the well has been pumped or bailed dry twice, it has been completely purged. Before purging a well, perform the following procedures: • Before evacuating or sampling, decontaminate all well probes, bailers, and other sampling devices as specified in SOP #1. Do not decontaminate dedicated downhole pumps. • Place clean plastic sheeting around the well. • Open the well and measure static water level following SOP #2. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 10 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 • Calculate the saturated borehole volume as specified in Section 4.2. • Calibrate field parameter measurement equipment as specified in SOP #9. • Obtain an initial sample from the bailer or purge pump for field measurements (e.g., temperature, conductivity, and pH measurements) and observation of water quality. • Begin purging three saturated borehole volumes of water with a bailer or pump. Take temperature, specific conductance, and pH measurements after evacuating each 1/4 to 1/2 (if practical) saturated borehole volume. Generally, pH values within ±0.1 pH unit and conductivity within ±10 percent throughout one saturated borehole volume indicate good stability of the water chemistry. If the chemistry is not stable, continue purging. • When evacuating a well using a pump, place the pump intake as follows: for low recovery wells (wells that pump dry at low rates), place the pump intake at the bottom of the screened interval for high recovery wells (wells that experience little drawdown with pumping), place the pump near the top of the water level to ensure the removal of stagnant water from the well bore. Purge the well at a rate that will not significantly draw down the well. • Bail or pump dry low -yielding wells during evacuation. If possible, let low - yielding wells recover before purging them dry again. If recovery is very slow, obtain samples as soon as sufficient water is available, but samples must be collected within 24 hours. 5.2 Obtaining Water Samples Ground water sample documentation, preservation, handling, packaging, and chain -of -custody procedures are specified in SOP #7. Collect ground water samples as follows: 1. Obtain samples for chemical analysis within two hours after purging is completed, if possible. For slow recovering wells, collect the sample immediately after a sufficient volume of water is available. Collect the water quality samples from within the well screen interval. 2. Assemble decontaminated sampling equipment. If bailers are used, use new nylon rope for each well for each sampling episode. Assemble the filtering apparatus. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 11 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 3. Make sure that sample labels have been filled out for each sample bottle as specified in SOP #7. 4. Place labels on bottle and tape over. 5. Lower the bailer slowly and gently into contact with the water in the well. Lower the bailer to the same depth in the well each time, within the screened interval. If submersible or bladder pumps are used to collect samples, reduce the discharge rate to about 100 milliliters per minute or as low as possible (Note: Some pumps may overheat at 100 milliliters per minute). Before collecting samples, pump the well at the reduced rate until the volume of water in the discharge hose has been purged. 6. Retrieve the bailer smoothly and empty the water in a slow, steady stream into the sample containers or direct the pump discharge into the sample containers. 7. Retrieve additional samples and slowly fill the sample bottles for all other analyses and QA/QC samples. Cap the sample bottles quickly. 8. Filter samples that require filtration with a disposable filter apparatus and peristaltic pump or electric submersible pump, as specified in SOP #7. 9. Slowly pour an unfiltered portion into the sample container for field parameter (e.g., pH, specific conductance, and temperature) analyses, perform the in -field analyses, and record the results. 1. Preserve samples as specified in SOP #7. 2. Place samples in baggies. 3. Place samples on ice in a cooler. 4. Record time of sampling. 5. Replace and lock well cap. 6. Complete field documentation and chain of custody record. 5.3 Field Quality Assurance/Quality Control Procedures and Samples Collect QA/QC samples during ground water sampling, as specified in the project planning documents. All QA/QC samples should be analyzed at the same time and in the same batches as the primary samples. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 12 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 QA/QC samples help identify potential sources of sample contamination and help evaluate potential error introduced by sample collection and handling. Label all field QA/QC samples with QA/QC identification numbers (i.e., "02" for duplicate samples, "03" for field blanks, "04" for rinsate samples, and "MS" for matrix spike samples) and send them to the laboratory with the other samples for analyses. Duplicate Samples To check for the natural sample variance and the consistency of field techniques and laboratory analysis, collect duplicate samples side -by -side with primary samples. For ground water sampling, collect a duplicate sample while collecting the primary sample. Fill the primary sample bottle(s) first and the duplicate sample bottle(s) for the same analysis second until all necessary sample bottles for both the primary and duplicate samples have been filled. Use different filter and tubing for the primary and duplicate samples. Handle the duplicate ground water sample in the same manner as the primary sample. Assign the duplicate sample the QA/QC identification number "02"; follow SOP #7 for documentation, preservation, handling, packaging, and chain -of -custody procedures; store the sample in an iced cooler; and ship it promptly to the laboratory so that analyses can be performed within required holding times. Collect one duplicate sample for every 20 primary samples collected so that a rate of at least 5 percent of primary samples collected is achieved. For example, if you collect from 1 to 20 primary samples during a sampling event, collect one duplicate sample, and if you collect from 21 to 40 primary samples during a sampling event, collect two duplicate QA/QC samples. Collect duplicate QA/QC samples so that they represent the time of collection, different sampling teams, field conditions, and sampling equipment variability. For example, if ambient conditions are altered that could impact sample quality, the QA/QC sampling frequency may be increased. Collect duplicate samples throughout the sampling event, not just at the end. Field Blanks Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 13 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 Collect field blanks by filling sample containers in the field with deionized water from the same source that is used for decontamination. Assign the sample the QA/QC identification number "03"; follow SOP #7 for documentation, preservation, handling, packaging, and chain -of -custody procedures; store the sample in an iced cooler; and ship it promptly to the laboratory so that analyses can be performed within required holding times. Collect one field blank sample for every 20 samples primary collected, so that a rate of at least 5 percent of primary samples collected is achieved. For example, if you collect from 1 to 20 primary samples during a sampling event, collect one field blank sample; and if you collect from 21 to 40 primary samples during a sampling event, collect two field blank samples. Rinsate Samples An equipment rinsate sample of sampling equipment is intended to be used to check if decontamination procedures have been effective. For the well sampling operation, collect a rinsate sample from the decontaminated sampling equipment (bailer or pump) and filter equipment before using it to obtain the sample. To collect a rinsate sample from a bailer, rinse deionized water over the decontaminated bailer and transfer it to the sample bottles. To collect a rinsate sample from an electric submersible pump, transfer the final deionized water rinse that is pumped through the discharge hose to sample bottles. The same parameters that will be analyzed in the ground water samples will be analyzed in the rinsate samples. Assign the rinsate sample the QA/QC sample identification number "04"; follow SOP #7 for documentation, preservation, handling, packaging, and chain -of -custody procedures; store the sample in an iced cooler; and ship it promptly to the laboratory so that analyses can be performed within required holding times. Collect one rinsate sample for every 20 primary water samples collected so that a rate for rinsate samples of at least 5 percent of primary samples collected is achieved. For example, if you collect from 1 to 20 primary samples during a sampling event, collect one rinsate blank sample, and if you collect from 21 to 40 samples during a sampling event, collect two rinsate blank samples. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 14 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 Collect rinsate blank samples so that they represent the time of collection, different sampling teams, field conditions, and sampling equipment variability. For example, if ambient conditions are altered that could impact sample quality, the QA/QC sampling frequency may be increased. Collect rinsate blank samples throughout the sampling event, not just at the end. Collect one rinsate blank sample for each type of sampling equipment used if less than 20 samples are collected (e.g., if 10 samples are collected by a bailer and 10 samples are collected by a submersible pump, you would collect two rinsate samples —one from the bailer and one from the pump). Matrix Spike Samples Matrix spike (MS) samples are required to evaluate potential matrix effects on sample analyses for all inorganic parameters. The laboratory will spike matrix spike samples for the inorganic parameters. Depending on the specific laboratory and sample volume collected, the matrix spike samples may be split from an existing sample or may require a separate sample. To samples that you collect specifically for matrix spike analysis, assign the QA/QC identification "MS"; follow SOP #7 for documentation, preservation, handling, packaging, and chain -of -custody procedures; store the sample in an iced cooler; and ship it promptly to the laboratory so that analyses can be performed within required holding times. The samplers will identify all samples selected for matrix spike split analysis on the Chain of Custody Form. Specify one matrix spike sample for each sample shipment group of 20 samples or less. Laboratory Replicate Depending on the laboratory conducting the analysis, laboratory replicate samples may be required. Laboratory replicate samples are split from the primary sample in the laboratory and analyzed as part of the laboratory's QA/QC program. The laboratory replicate does not require a separate sample volume. The sample that the laboratory splits must be identified by the samplers on the Chain of Custody Form. One laboratory replicate sample will be specified for each sample shipment group of 20 samples or less.

Divide sample identification numbers that are assigned into three fields, as shown in the following examples: Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 2 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 • Telesto1-01-01-011705 (primary sample at Telesto-01) • CCS-03-02-950318 (duplicate sample at Cottonwood Creek Station 03) • MW -01-3.5-4.0-01-960216 (primary sample at MW -01 from 3.5 to 4.0 feet). The first field (e.g., Telesto-01, CCS-03, or MW -01-3.5-4.0) uniquely identifies the specific sample and is usually tied to the location, matrix sampled, and/or specific sample depths. If required, any additional site -specific identification can be encoded within the sample location field. The second field identifies whether the sample is a primary (01), a field duplicate (02), field blank (03), equipment rinsate (04), or matrix spike (MS) sample. The third and final field contains the date in a day month year format to allow data in the analytical database to be sorted easily. For example, the first sample identified above was collected on January 17, 2005 4.2 Sample Labeling Label each sample that is collected in the field for future identification. Before collecting the sample, a member of the sampling team will fill out sample labels as completely as possible with black waterproof ink. In most cases, sample labels need to be obtained from the analytical company. Each label will contain at least the following information: • Sampler's company affiliation • Unique identification number • Date and time of sample collection • Analyses required • Method of preservation used • Sampler's signature. After the label is completed and attached to the sample container, place clear tape over the label to protect and secure it to the bottle. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 3 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 4.3 Sample Containers, Preservatives, Filtration, and Holding Times 4.3.1 Sample Containers Observe proper sample preparation practices (Section 4.5) to minimize sample contamination and potential repeat analyses due to anomalous analytical results. Before sampling, obtain commercially -cleaned sample containers from the analytical laboratory. Keep all documentation regarding sample bottle decontamination. Label the bottles as described in the Section 4.2. If sample bottles have not been pre -preserved from the laboratory, add preservatives in the field after sample collection. 4.3.2 Sample Preservation Samples are preserved to prevent or minimize chemical changes that could occur during transit and storage. Preservation methods include placing samples on ice and adding certain chemicals. If sample bottles are not pre -preserved, preserve samples immediately after collecting them to ensure that laboratory results are not compromised by improper coordination of preservation requirements and holding times. If sample bottles are pre -preserved, allow the sample to free fall into the container and do not allow it to overflow. Store samples on ice in coolers before and during shipping. Specific sample preservation requirements will be specified in the project work plan or sample plan and should be discussed with the laboratory before performing the sampling episode. Verify the proper pH of the sample after preservation. Use disposable pH test strips to quickly and conveniently verify proper preservation. Do not immerse the pH test strips directly into the sample bottle; instead, wet the strips with a small aliquot of the sample. 4.3.3 Sample Filtration Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 4 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 Filter samples that will be tested for dissolved cations and metals through a 0.45 -micron filter. Two common filtration methods use either disposable filter cartridges or disposable filters in a reusable filter holder. If possible, use disposable filter cartridges, because these will eliminate both decontamination and the possibility of cross -contamination. Attach the disposable filter cartridge to disposable silicon or Tygon® tubing and connect the combination to a peristaltic pump or directly to the electric submersible pump discharge. If reusable filter holders are used, be sure to decontaminate the filtration apparatus to avoid cross - contamination. Decontaminate filter holders as specified in SOP #1. Follow manufacturer's operating directions when operating filter holders and/or peristaltic pumps. Regardless of the filtration method used, flush the filter and tubing with at least 100 milliliters of sample water before collecting samples. An intermediate container may be required to hold the unfiltered sample. For the intermediate container, use a new, unused sample bottle or a container that has been decontaminated before use as specified in SOP #1. Filter samples that require chemical preservation before preserving them. 4.3.4 Sample Holding Times and Analyses Sample holding times are established to minimize chemical changes in a sample before analysis and/or extraction. A holding time is defined as the maximum allowable time between sample collection and analysis and/or extraction, based on the nature of the analyte of interest and chemical stability factors. Holding times will be specified in the project work plan or sample plan and should be discussed with the laboratory before performing the sampling episode. To minimize the possibility of exceeding holding times, send samples to the laboratory as soon as possible after collection by hand delivery or an overnight courier service. The chemical constituents, preservation, and holding times for samples will be summarized in the project work plan or sample plan. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 5 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 4.4 Sample Packaging for Shipping To maintain the required storage temperature, ship the samples by the quickest route. Do not allow travel time to exceed 24 hours. Inform the analyzing laboratory of the shipment and of the carrier handling the shipment. Ship the samples in a sealed, ice -filled cooler of good quality. Place the appropriate completed chain -of -custody (COC) forms in each cooler. The field sampling team shall pack non -hazardous samples for shipment as follows: 1. Obtain an appropriately sized cooler of good quality to pack the samples. 2. Line the cooler with a large plastic trash bag. 3. Place each sample bottle in a appropriately sized freezer zip -lock plastic bag, and place the bottle upright in the large plastic trash bag lining the cooler. 4. Double -bag ice in 1 -gallon freezer zip -lock plastic bags. Use enough ice to keep the samples cool until they are received by the laboratory. Use more ice in the summer time. 5. If required, use vermiculite or a similar absorbent material to fill voids in the cooler. 6. Verify that all samples in the cooler have been documented on the COC form. Record the number of the Federal Express Air Bill or other shipping record document on the COC form. Sign and date the COC form and retain a copy of it. Place the COC form in a 1 -gallon zip -lock plastic bag and tape the COC form to the inside lid of the shipping cooler. 7. Seal the plastic trash bag liner with a signed custody seal. This will maintain the chain -of -custody if the cooler is inadvertently opened during shipment. 8. Seal the cooler and drainhole with plastic or fiber tape. 9. Attach signed custody seals across two sides of the cooler top. 10. Attach an address label with the laboratory address and phone number and with a return address and phone number.

Attach a Federal Express Air Bill or another shipping document. Retain a copy of shipping documents with the COC form. 12. Notify the laboratory of the sample shipment. 13. Verify that the laboratory receives the samples and that the samples were received in good condition and were sufficiently cool. Transfer the samples in a timely fashion. Holding times and instructions for preservation for the parameters to be analyzed will be specified in the work plan. The laboratory must receive the samples as soon as possible to ensure that analysis and, if the need arises, re -analysis can be performed within the required holding time. Carefully evaluate samples collected at hazardous waste sites to determine if they should be classified as dangerous goods. If they are hazardous, contact the shipping company to determine the proper shipping procedure. In some cases, state department of transportation laws may apply and should be considered. 4.5 Sample Handling General sample handling procedures will include the following: • Always make field measurements on a separate sub -sample, not on the sample that is sent to the laboratory for analysis, and discard it after the measurements have been made. • Sample bottles shall be properly decontaminated if they are not certified clean by the manufacturer or have not been pre -preserved by the laboratory. • Do not use bottles that have been used in the laboratory to store concentrated reagents as sample bottles. • Do not allow the inner portion of sample containers and caps to come into contact with bare hands, gloves, or other objects. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 7 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 • If contact with air would change the concentration or characteristics of a constituent to be determined, secure the sample without contacting it with air and completely fill the container. • Keep sample containers in a clean environment away from dust, dirt, fumes, and grime. Keep vehicles clean to help eliminate contamination problems. • Field personnel shall wear disposable latex or nitril gloves when collecting samples. • Do not let foreign and metal objects contact acids and water samples. • Do not measure electrical conductivity on a sample that was first used to measure pH. Potassium chloride that diffuses from the pH probe can alter the conductivity of the sample. • Do not let samples stand in the sun. Store them in a cool place, preferably in ice chests with ice. • Ship samples to the laboratory without delay. 5.0 SAMPLE DOCUMENTATION AND CHAIN OF CUSTODY Documentation of the conditions and procedures used to collect, calibrate, treat, and handle samples and field data is one of the most important aspects of any monitoring program. Proper documentation provides sources to determine the integrity and applicability of the data. Carefully document all field activities in a logbook or on data sheets. Logbooks shall be bound with numbered pages and shall be written in with permanent black ink only. Record field activities in sufficient detail so that field activities can later be reconstructed from the notes. Any changes to the notes in the field book shall be made by drawing a single line through the incorrect material and initialing the markout. The following sections provide procedures and formats for documenting the field data and conditions at the time of sample collection, shipment to the laboratory, and laboratory analysis. While forms are provided to document specific tasks, the field sampling team shall maintain a field book for recording all other events, conditions, and observations during sampling. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 8 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 5.1 Field Notes Documentation of observations and data acquired in the field provide information on sample acquisition, field conditions at the time of sampling, and a permanent record of field activities. Record field observations and data collected during routine monitoring activities with waterproof ink in a permanently bound weatherproof field log book with consecutively numbered pages or on field data sheets. Field notebook and data sheet entries will include at least the following information. Consult relevant sampling and decontamination SOPs to supplement this list. • Project name • Location of sample • Sampler's printed name and signature • Data and time of sample collection • Sample identification numbers • Description of sample (matrix sampled) • Sample depth (if applicable) • Number and volume of samples • Sample methods, or reference to the appropriate SOP • Sample handling including filtration and preservation, as appropriate for separate sample aliquots • Field observations • Results of any field measurements, such as depth to water, pH, temperature, specific conductance • Personnel present Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 9 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 • Decontamination procedures. Strike out changes or deletions in the field book or on the data sheets with a single strike mark and be sure that the original information remains legible. Record enough information to allow the sampling event to be reconstructed from the notes alone. Completely fill out field data sheets and do not leave blank lines. Write "Not Applicable" or "NA" on blank lines. All field books will be signed daily by the person who made the entries. 5.2 Chain Of Custody Procedures The custody of all samples shall be documented on COC forms provided by the laboratory. The COC forms will document possession of the sample from collection through laboratory analysis. Follow appropriate sample custody and documentation procedures precisely to preserve sample integrity and to ensure the validity of field and laboratory data. As a result, all sample data will be traceable from the time and location of sample collection through chemical analyses and to the time when data are used. As described above, record initial information concerning sample collection in the field log book or on data sheets. Information on the custody, transfer, handling, and shipping of samples will be recorded on a Chain -of -Custody (COC) Form. The objective of the custody identification and control system for the samples is to ensure, to the extent practicable, that the following occur: • All samples scheduled for collection are uniquely identified. • The correct samples are analyzed and are traceable to their records. • Important sample characteristics are preserved. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 10 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 • Samples are protected from loss or damage. • Any alteration of samples (e.g., filtration, preservation, and dilution) is documented. • A forensic record of sample integrity is established. • Legally traceable custody and possession records are maintained. For this project, a sample is defined as being in an individual's custody if the following conditions occur: • The sample is in that individual's actual physical possession. • The sample is in that individual's view after being in their physical possession. • The sample is in that individual's physical possession and then locked or otherwise sealed so that tampering will be evident. • The sample is maintained in a secure area that is restricted to authorized personnel only. General field custody procedures include the following: • As few people as possible should handle samples. • The field sampler is personally responsible for the care and custody of the samples collected until they are properly transferred. • When transferring the samples, the individuals relinquishing and receiving the samples will document the transfer by signing, dating, and writing the time of the transfer on the COC form. • The person responsible for delivering the samples to the laboratory or to the shipping carrier will sign the COC form, retain the third copy of the form, document the method of shipment, and send the original and the second copy of the form with the samples. Upon arrival at the laboratory, the person receiving the samples will sign the COC form and return the second copy to the Project Manager. • Custody seals must be attached so that it is necessary to break the seal to open the shipping container. The person affixing the custody seal will sign and date the seal.

This SOP describes the equipment and field procedures necessary to measure field parameters. Whenever water samples are collected, measure field parameters on a separate aliquot of the sample immediately after collecting the sample. This SOP describes how to properly calibrate instruments and measure pH, temperature, conductivity, and turbidity in the field. Many types of meters and methods are used to measure field parameters. The following sections: (1) list specific equipment requirements, (2) clarify the objectives of measuring field parameters to help the samplers obtain the proper equipment, and (3) describe the required apparatus for performing the measurements. 2.0 RELATED STANDARD OPERATING PROCEDURES This procedure is intended to be used with the following SOPs: SOP # Title 1 Equipment Decontamination 3.0 pH METER CALIBRATION AND MEASUREMENT 3.1 Required pH Measurement Equipment Use the following apparatus and supplies for measuring pH in the field: • Portable Hach One pH Meter Model 43800-00 with Hach One Combination pH Electrode Model 48600 or the EC10 Portable pH/mV/Temperature Meter Model 50050 with the Combination pH Electrode with Temperature (Gel -filled) Model 50200 • Spare electrolyte cartridge, if required Shepherd Miller, Inc. r:Iweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendixa_sop09 inst calib and measurement.doc1 Januaty 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 • Hach pH Electrode Storage Solution, Catalog No. 50301-49 • Extra batteries • Beakers • Buffer solutions of pH 4, 7, and 10 • Deionized or distilled water and wash bottle • Kimwipes or equivalent. Many chemical reactions are pH -dependent; therefore, pH is an important indicator of the state of the water. If possible, determine the pH in situ; if this is not possible, determine the pH from a water sample as soon as possible. Determine the pH by the electrometric method using standard buffer solutions. The electrometric method is the preferred method because of its greater accuracy and ease of measurement. A combination electrode, which combines the glass membrane electrode and the reference electrode, may also be used. Many portable battery -powered pH meters are available with a variety of features and abilities. The meter selected for field use should be rugged and it should be carried and stored in a foam -lined, water-resistant carrying case. The carrying case should have sufficient room to store extra pH buffers, electrode filling solution, spare electrodes, cables, and batteries. Meters recommended should automatically compensate for temperature and be capable of calibration with a two -point (two buffers) slope adjustment method. The meter should have a precision of +0.05 units. 3.2 pH Meter Calibration Procedures Before collecting samples, calibrate the pH meter in accordance with the manufacturer's instructions using calibration solutions. The field sampling team shall record all pH measurement data, including calibration dates, readings, SMI meter number, and temperatures, on a data sheet or in a Shepherd Miller, Inc. r:lweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc2 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 field notebook. The field sampling team shall be familiar with the meter and shall follow the manufacturer's instructions for calibrating and using the meter. Appendix A presents the manufacturer's manual for the Portable Hach One pH Meter Model 43800-00, Hach One Combination pH Electrode Model 48600, the EC10 Portable pH/mV/Temperature Meter Model 50050, and the Combination pH Electrode with Temperature (Gel -filled) Model 50200. Calibrate the pH meter at the start of each sampling day and, as needed, when measuring waters with different pH values. Thoroughly document all calibrations, including the buffer readings and temperatures in the field book or data sheets. The field sampling team shall do the following when calibrating the meter according to the manufacturer's procedures: • Condition new pH electrodes by soaking them for one hour in Hach pH Electrode Storage Solution. Do not condition pH electrodes that have been properly stored in Hach pH Electrode Storage Solution. • One of the buffer solutions used for the slope adjustment should bracket the anticipated pH of the sample, and the other buffer should always have a pH of 7. Ensure that the buffer solutions are at the same temperature and are as close as practical to the temperature of the water to be measured. Use buffer solutions once and then discarded them. • Before immersing the probe into the buffer or sample, rinse the probe with deionized or distilled water and blot it dry with a clean wipe. Protect the glass tip of the probe from abrasion and scratching. • Adjust the slope of the meter with two buffer solutions (2 -point slope adjustment) at least daily, and preferably twice per day to account for changes in conditions of the probe and meter and, as needed, when measuring waters with different pH values. • If the slope deviates significantly from its theoretical value, search for a potentially defective electrode or contaminated buffer solution. Shepherd Miller, Inc. r:lweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc3 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 3.3 pH Measurement The sampler shall measure pH in the field as follows: 1. Thoroughly check the pH meter, including the battery, and then calibrate the meter in the laboratory before taking it to the field. The buffers used for calibration should bracket the anticipated pH values to be measured. 2. Recalibrate the meter in the field before use. 3. If the pH is measured in a container, rinse the sample container with deionized water and then rinse it three times with the sample water prior to measurement. Rinse the pH probe with deionized water and, if possible, blot the probe dry with a clean wipe. Be sure to protect the fragile glass bulb at the end of the probe from damage. 4. Immerse the electrode into the water, allow the pH reading to stabilize, and monitor the drift of the instrument. Do not immerse the electrode above the top of the pH probe. When the pH reading stabilizes, record the temperature and the pH reading to the nearest 0.01 unit. 5. Between measurements, store the electrode in pH Electrode Storage Solution. 6. Measure samples within a short period of time after sampling and on a separate aliquot of the sample. 7. For the Hach One Combination pH Electrode Model 48600, dispense electrolyte if the reading becomes unstable, erratic, or if stabilization takes too long. An unstable reading may also indicate an air bubble in the reference line. Depress the dispenser button repeatedly until the bubble is expelled (5 to 10 clicks should be sufficient). Note that it is not necessary to refresh the electrolyte gel at the reference outlet between readings unless the reading is not stable. 8. Short-term electrode storage (between measurements/up to one week) will be in the Hach pH Electrode Storage Solution or cotton soaked in the Hach pH Electrode Storage Solution. Do not store in deionized water, as this will shorten the electrode life. 4.0 CONDUCTIVITY METER CALIBRATION AND MEASUREMENT Electrical conductivity, or specific conductance, is the ability of water to conduct an electric current and depends on the concentration of ions in solution. The relationship between conductivity and the concentration of dissolved solids is approximately linear for most natural waters. Changes in this Shepherd Miller, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc4 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 relationship indicate changes in the proportions of different salts and, therefore, changes in the sources of dissolved substances that enter the water body. Conductivity is usually measured in the field with a hand-held meter that is equipped with a conductivity cell and temperature probe. The meter measures the ability of water to conduct electricity across a specified distance and cross-sectional area. Numerous types of conductivity meters are available with various features and accessories. For measuring conductivity in the field, use a meter that can also measure temperature, has either a manual or automatic temperature compensator, and that displays conductivity directly in units of microsiemens per centimeter (µS/cm), corrected to a temperature of 25 degrees Centigrade (°C). Carry and store the meter in a foam -lined, water-resistant carrying case. The carrying case should have sufficient room to store extra calibration solution, spare probes, and batteries. 4.1 Conductivity Measurement Equipment Use the following apparatus and supplies for measuring conductivity in the field: • Hach CO150 Conductivity Meter Model 50150, Hach Conductivity/TDS Meter Model 44600, or Oakton® WD -35607-10 Hand -Held Conductivity Meter • Extra battery • Calibration solutions which bracket expected range of measurements • Deionized water • Wash bottle • Kimwipes • Beakers. 4.2 Conductivity Meter Calibration Shepherd Miller, Inc. r:lweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc5 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 Before collecting samples, calibrate the conductivity meter using calibration solutions in accordance with the manufacturer's instructions (Appendix B). The sampler shall record all conductivity measurement data, including calibration dates, readings, SMI meter number, and temperatures, on a data sheet or in a field notebook. Reagent -grade potassium chloride (KC1) or other equivalent solutions are universally used as reference solutions to calibrate conductivity (specific conductance) equipment. The reference solutions are also used to check the accuracy of the meter, usually on a daily basis or, as necessary, at more frequent intervals. The conductivity of the reference solutions that are used to calibrate the meter should bracket the expected range of the conductivity of the water samples. Commercially prepared calibration standards are available from laboratory suppliers at many standard concentrations. The sampler shall calibrate the meter as follows: 1. Calibrate the meter according to the manufacturer's instructions. 2. Prepare or obtain standard reference solutions of a known value at a known temperature. Adjust the meter or the calibration solution to the correct temperature. 3. Adjust the meter to read the reference conductivity. Rinse the probe with deionized water and blot the probe dry. Re -immerse the probe in the reference solution and read the measured value to validate the corrected conductivity. 4.3 Conductivity Measurement Whenever possible, measure conductivity in situ or immediately after a sample is collected. If conductivity is measured within 24 hours, do not filter the conductivity sample beforehand. Record conductivity readings to the nearest 0.1 µS/cm, corrected to 25°C . The sampler shall measure conductivity as follows: Shepherd Miller, Inc. r:lweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc6 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 1. Check the meter, including the battery, and calibrate the meter before taking it to the field. Buffer solutions used for calibration should bracket the expected conductivity values to be measured. 2. Recalibrate the meter in the field before use. 3. Rinse the probe with deionized water and blot the probe dry with a clean wipe, without wiping the plating on the cell. 4. Insert the probe into the sample solution. Immerse the tip to or beyond the vent holes and agitate the probe vertically. Make sure that air bubbles are not trapped near the temperature sensor. Allow the reading to stabilize before recording measurements. Measure and record the temperature of the sample. 5. During normal use, rinse the probe thoroughly with deionized water between measurements to minimize the buildup of interfering substances on the probe element. 6. Because the Model 44600 Conductivity Meter does not automatically turn itself off, verify that the unit is off before storing it. 5.0 TURBIDITY METER CALIBRATION AND MEASUREMENT One of the most sensitive and, therefore, the most representative field parameter measured during ground water sample collection is turbidity. Measure turbidity in the field with the Hach Portable Turbidimeter Model 2100P. The Hach Portable Turbidimeter Model 2100P manual is presented in Appendix C. 5.1 Turbidity Measurement Equipment Use the following apparatus and supplies for measuring turbidity in the field: • Hach Portable Turbidimeter Model 2100P • Extra battery • Calibration solutions which bracket expected range of measurements • Silicone oil • Deionized water Shepherd Miller, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc7 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 • Wash bottle • Liquinox solution • Kimwipes • Beakers. 5.2 Turbidity Meter Calibration and Measurements Calibrate the turbidimeter before mobilizing to the field. Once in the field, check the calibration by measuring standards of known turbidity as specified in the calibration and measurement procedures presented in Appendix C. The field sampling team shall record calibration checks, dates, and the SMI meter number on a field data sheet or in the field book. Note the following operational considerations: • Avoid prolonged exposure to ultraviolet light and sunlight. • Do not hold the instrument during measurements; place the instrument on a flat, steady surface. • Measure samples immediately to prevent temperature changes and settling. Avoid sample dilution when possible. Particles suspended in the original sample may dissolve or otherwise change characteristics when the sample temperature changes or when the sample is diluted, resulting in a non -representative sample measurement. • Handle measurement cells only by the top to minimize dirt, scratches, and fingerprints in the light path. • Always cap the sample cell to prevent spillage of sample into the instrument. • Always close the sample compartment lid during measurement and storage. • When oiling the sample cells, use only a thin coat of oil. Do not use excessive amounts of oil. The sampler shall measure turbidity as follows: Shepherd Miller, Inc. r:lweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc8 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 1. Thoroughly check the meter, including the battery, and then calibrate the meter in the laboratory before taking it to the field. 2. Measure the turbidity of the standard and compare it to its certified value. 3. Clean the sample cell. 4. Fill the sample cell with sample. 5. Clean and oil the sample cell. 6.

A search of our database indicates that two sites (5WL.10 and 5WL.841) are located within or adjacent to the permit area. Site 5WL.10 did not have an assessment provided on the form, and site 5WL.841 is a segment of the officially eligible Great Western Railroad. As there are no properties of historical significance included or nominated for inclusion in the state register currently documented within the proposed permit area, a finding of no adverse effect to significant properties is appropriate. As most of Colorado has not been inventoried for cultural resources, our files contain incomplete information. Consequently, there is the possibility that as yet unidentified cultural resources exist within the proposed permit area. The requirements under CRS 24-80 part 13 apply and must be followed if human remains are discovered during ground disturbing activities. Please note that if the fill or disposal site location is associated with a Federal undertaking, it is the responsibility of the federal agency to meet the requirements of Section 106 as set forth in 36 CFR Part 800 titled "Protection of Historic Properties". This includes not only reasonable and good faith identification efforts of any historic properties located within the area of potential effects, but determining whether the undertaking will have an effect upon such properties. The State Historic Preservation Office, Native American tribes, representatives of local governments, and applicants for federal permits are entitled to consultative roles in this process. We thank you for the opportunity to comment. If we may be of further assistance, please contact Holly McKee -Huth, Cultural Resource Information/Section 106 Compliance at (303) 866- 4670/hollv.mckeela,state.co.us.

Structures to be Augmented: 33.1 Walters and Bokelman Pits. Located in the SW1 of the NE1, the SE'. and the EY2SW'ia. Section 24, T5N, R6#W, 611 P.M., Larinicr County, Colorado, as shown on the attached Exhibit B. 33.1.1 Gravel pits located in Walters Cells 1, 2 and 3 will be inside a shiny wall that does not intercept ground water, and therefore, these gravel pits shall be lined pits that do not require augmentation. Gravel pits located in Waiters Cell 4 will be unlined and therefore evaporative depletions from ground water exposed in these gravel pits shall be augmented pursuant to the plan for augmentation decreed herein. Gravel pits located in Bokelman Cells 1, 2 and 3 will be inside a slurry wall that does not intercept ground water, and therefore, these gravel pits shall be lined pits that do not require augmentation. LRM shall replace out of priority evaporative depletions at each gravel pit until the State or Division Engineer approves the liner for each pit. 33.2 Green and Croissant Pits. Located in the NW'/, and the W1/4 of the NE1, Section 30, T5N, R67W, 6th P.M., Weld County, Colorado, as shown on the attached Exhibit B, 33.2.1 Gravel pits located in all four cells at the Green and Croissant Pits site will be unlined and therefore evaporative depletions from ground water exposed in these gravel pits will be augmented pursuant to the plan for augmentation decreed herein. 34. Uses: Unlined gravel pits at the Walters and Bokelman Pits site and the Green and Croissant Pits site ("Gravel Pits") expose tributary ground water. Out of priority evaporation losses from the unlined Gravel Pits must be replaced. In addition, water from the Gravel Pits is used for mining, product washing and processing, concrete production Case No. 09C WI fly Fmehngs a/Fret, Canchcs/(err.+ Judgment and Decree Page IN of S and dust suppression. Water contained within the mined products removed from the Gravel Pits must also be replaced. The additional uses described in paragraphs 35.5 and 35.6 must also be replaced. As of the date of this decree, the above described uses continue at the Walters and Bokelman Pits site and the Green and Croissant Pits site. After mining ceases at the Gravel Pits, washing and processing operations for products mined from other sites, concrete production and dust suppression may continue. To the extent that these depletions are out of priority, the purpose of this plan is to provide for replacement of such out of priority depletions in time, location and amount, under the teniis of this decree. to the extent necessary to prevent material injury to senior vested water rights and decreed conditional water rights. The Court approves the plan for augmentation subject to the terms and conditions of this decree. 35. Description of Depletions to be Augmented: 35.1 Mining and Production Losses. 35 acre-feet per year of consumption from gravel and rock mining uses. which include product washing, concrete production and other processing of mined rock products, water incorporated in or adhering to rock products and dust suppression. Consumption from product washing and processing shall be calculated as 9.6 gallons of water per ton of aggregate sold, or 4% of the total mined volume. Consumption from concrete production shall be calculated based on the volume of concrete produced times 30 gallons of water per cubic yard of concrete. Consumption from dust suppression shall be measured and is fully consumptive. For planning purposes, LRM estimates maximum dust suppression use of approximately 352,667 gallons per month during peak use months of July through September, with minimum dust suppression use of approximately 46,000 gallons per month occurring in December through February. After completion of mining at the sites, LRM will continue to use the processing plant to process material mined from other properties, and such use at the sites shall not exceed 25.5 acre-feet per year. 35.2 Evaporation. Pursuant to CRS §37-92-305(12), LRM is not required to replace evaporation from ground water exposed to the atmosphere from mining the Gravel Pits in an amount equal to the amount of historical natural depletions caused by the preexisting natural vegetative cover on the surface of the area which will be, or which has been, permanently replaced by the open water surface of the Gravel Pits. Accordingly, LRM is only required to augment the net evaporation from ground water exposed to the atmosphere by mining the Gravel Pits. Net evaporation is equal to the gross evaporation from the Gravel Pits that results from ground water exposed to the atmosphere from mining less the historical natural depletions. During mining, the exposed surface area at each site will vary, and at times exposure at the Walters and Bokelman Pits site or the Green and Croissant Pits site may exceed the exposed surface area for each site identified in Paragraphs 35.3 and 35.4. LRM shall also augment gross evaporative depletions from stock ponds located at the Green and Croissant Pits Site. As mining is completed in certain gravel pits and commences or continues in other gravel pits, backfilling of portions of CL7,1f' No. 09C U l0} Frne..h i s• g/'l i ei, Conches/On.Conches/0ns of Lair. Judgment and Dec -lye Page 19u1'28 completed gravel pits shall occur to hunt the total exposed surface area of unlined gravel pits at the Walters and Bokelman Pits site and the Green and Croissant Pits site and the stock ponds to 65 acres. Total net evaporation at the Gravel Pits and gross evaporation at the stock ponds will consume 166 acre-feet per year. 35.2.! Depletions caused by the gross evaporation from the Gravel Pits and stock ponds were estimated using the gross lake evaporation rates obtained from the National Oceanic and Atmospheric Administration Evaporation Atlas (NOAA Technical Report N WS 33), which averages 3.35 acre-feet per acre per year. 35.2.2 Historical natural depletions occurred due to consumption by grasses and irrigated crops, and natural non -irrigated vegetation on the land which is now, or will be, permanently replaced by an open water surface at the Gravel Pits. The historical natural depletions associated with the lands covered bv irrigated crops is equal to the effective precipitation for irrigated land, which is equal to 70% of total precipitation. 35.2.3 As of the date of this decree there are three stock ponds at the Green and Croissant Pits Site with 6.3 acres of ground water surface area exposed to the atmosphere resulting in gross evaporative depletions averaging 21.11 acre-feet per year. In the event LRM eliminates one or more stock ponds in the future. LRM shall notify the Division Engineer and the parties and LRM shall modify the accounting to revise the calculation of evaporative depletions. Gross evaporative stock pond depletions shall be lagged to the Big Thompson River with the net evaporative depletions for the Green and Croissant Pits pursuant to Paragraph 36. I , 35.3 Walters and Bokelman Pits Evaporation. Upon completion of mining, up to 11.5 acres of ground water surface area will be exposed to the atmosphere by mining the unlined gravel pit at the Walters and Bokelman Pits site resulting in net evaporation averaging 28.37 acre-feet per year (gross evaporation less historical natural depletions). 35.4 Green and Croissant Pits Evaporation. Upon completion of mining, up to 47.2 acres of ground water surface area will be exposed to the atmosphere by milling the unlined gravel pits at the Green and Croissant Pits site resulting in net evaporation averaging 116.44 acre-feet per year (gross evaporation less historical natural depletions). 35.5 Additional uses: in-igation, piscatorial, fishing, fish culture and propagation, stock watering, wildlife, aesthetic, recreation, and fire protection uses. Irrigation consists of agricultural irrigation, which continues on portions of the sites as mining expands, and irrigation which may be part of the reclamation plans. Up to 100 acres of irrigation at the Walters and Bokelman Pits site and the Green and Croissant Pits site will result in an augmentation requirement of up to 170.79 acre-feet per year. LRM is not precluded from amending this plan for augmentation to seek credit for the irrigation CL7,1f' No. 09C Hi/ 05 F1nr.lnip' a/ lOC!, COM:hIS/ou. c1/ LuiL. Judgment and Decree Page y0ut r return flows in the future but may only take credit for the irrigation return flows upon approval of a substitute water supply plan or entry of an amended decree, as applicable, and such credit shall be subject to the terms and conditions of such SWSP or amended decree. Depletions for all additional uses will consume up to 171.79 acre-feet per year. 35.6 Once mining commences at Walters Cell 4 and Green and Croissant Cell 4, dewatering operations at the unlined gravel pits located at these sites will result in out of priority depletions to he replaced pursuant to this plan for augmentation. Dewatering water will be pumped from the unlined gravel pits located within Walters Cell 4 and Green and Croissant Cell 4 and delivered to the Big Thompson River and may be used for augmentation so long as all depletions attributable to dewatering are replaced. LRM estimates that it will dewater up to approximately 40.33 acre-feet per month at a rate of 300 gpm. However, the dewatering rate may fluctuate and at times be higher or lower than the currently estimated rate of 300 gpm. The augmentation credit resulting from dewatering is equal to the amount of water delivered to the Big Thompson River. Depletions resulting from dewatering shall be lagged to the Big Thompson River using the Glover Method and the AWAS Glover alluvial aquifer model or similar tool described in Paragraph 36 and using the aquifer parameters shown in the following table: Gravel Pit Y(ft] ys/0-0 S T(GPD/ft) Walters and Bokelman Pits Cell 4 661,0 981.0 0.2 50,000 Green and Croissant Pits Cell 4 738.0 2,280.0 0.2 50.000 The amount of water delivered to the Big Thompson River during dewatering operations shall be metered daily and accounted for monthly. 35.7 The maximum net amount of depletion that, to the extent it is out of priority, is required to be replaced pursuant to this plan for augmentation (net evaporation depletions + consumption m production washing and processing and concrete production and dust suppression + depletions from additional uses) is estimated to be up to approximately 361 acre-feet per year. Depletions are to a reach of the Big Thompson River downstream of the headgate of the Hill and Brush Ditch including the E1/2 of Section 24, Township SN. Range 68 W, Or' PM, Larimer County, Colorado and Sections 19 and 30. Township 5N, Range 67 W, 6th PM, Weld County, Colorado. 36. Timing of depletions: Due to the timing of evaporation and mining depletions, and the lagging effects of the aquifer, the net evaporation depletions to the river shall be distributed through the year using the following method and parameters: 36.1 The monthly net evaporative depletions from each Gravel Pit shall be lagged to the Big Thompson River using the Glover Method and the AWAS Glover alluvial aquifer model or similar tool. The AWAS model is based on the Glover Stream Depletion Method, and requires the definition of several aquifer and stream parameters.

LRM shall replace historical return flows for the changed Hillsborough Shares pursuant to the requirements of Paragraph 7.4.3. 39. Terms and conditions to prevent injury: 39.1 "First fill" is the water that fills an unlined gravel pit and occupies the volume previously occupied by the removed sand, gravel or other solid material. To prevent wireplaced out of priority depletions that may result from the "first fill" of the unlined Gravel Pits, LRM shall dewater the Gravel Pits except at times when in priority diversions may be made to fill all or some portion of the Gravel Pits or until LRM obtains Case No. 09Cit 70} Frnr.liugs a/ Fuet, Cuncln,+ron.+ Jurl mciN and Decree Page 23 o/'28 a substitute water supply plan approved by the State Engineer or plan for augmentation approved by the Water Court to augment out of priority depletions from the "first fill" of the Gravel Pits. In the event any diversion made in priority only fills a portion of an unlined gravel pit. LRM shall either re -commence dewatering to maintain the water level in such pit until additional in priority diversions can be made or LRM may continue out of priority diversions to fill such pit pursuant to an approved substitute water supply plan or Court approved augmentation plan that replaces out of priority depletions from the "first fill" for such pit. If pumps are used to make in priority diversions directly from the Big Thompson River to fill all or sonic portion of the Gravel Pits, there will be no lagged depletions. All out of priority depletions resulting from dewatering operations at the unlined Gravel Pits shall be replaced pursuant to Paragraph 35.6 of this augmentation plan. 39.2 After completion of mining at the Walters and Bokelman Pits site and Green and Croissant Pits site, LRM shall make a final determination of the total exposed surface acres at each site, and provide such determination to the Division Engineer for approval with notice to all parties of such determination and submittal to the Division Engineer, If no decision is rendered by the Division Engineer within 60 days of submittal, the determination shall be considered accepted by the Division Engineer. LRM shall also provide such determination to Central and all other parties upon request.

The Application herein is contemplated by law and this Court has jurisdiction over the subject matter of this proceeding and all persons affected thereby, whether they appeared or not. 43. Timely and adequate notice of the pendency of this action was given in the manner provided by law. 44. The plan for augmentation, the conditional water rights and change of water rights decreed herein are. as a matter of law, permissible and come within the definitions authorized by statute. 45. Well permit and plan for augmentation required: Pursuant to CRS §37-92-103(14), 437-90-137(1 1)(a) and Three Bells Ranch v. Cache la Porrdre PV -Wei -Users Assn.. 758 P.2d I 64 (Colo. 1988), a gravel pit that exposes ground water to the atmosphere, where application of the ground water to a beneficial use is part of an approved reclamation plan, is a "well." A well permit and plan for augmentation are required. 46. Approval of change of water rights. The change of water rights decreed herein meet all statutory and case law requirements for approval. 47. Approval of conditional water rights: The conditional water rights decreed herein meet all statutory and case law requirements for approval. 48. Approval of plan for augmentation: The plan for augmentation decreed herein meets all statutory and case law requirements for approval. 49. Pre-existing natural depletions: Pursuant to CRS 437-92-305(12), an augmentation plan for a gravel pit that exposes ground water to the atmosphere need not replace the amount of historic natural depletion to the waters of the state caused by the preexisting natural vegetative cover on the surface of the area which will be, or which has been, permanently replaced by an open water surface. Loveland Ready Mix has proven the historic natural depletion. 50. This Decree is administrable by the water officials of the State of Colorado provided that LRM furnishes to the Division Engineer or his representative upon request, appropriate accounting records. Case No. 09CWI Funliugs• o/ FiuY, Cunchc+/ou.+' Judgment crud Decree Page 26 01'28 51. No injury: This plan for augmentation will not injuriously affect the owner of or persons entitled to use water under any vested water right or decreed conditional water right. CRS §37-92-305(3). 52. Substitute water: The substituted water shall be of a quality and quantity so as to meet the requirements for which the water of senior appropriators has normally been used, and such substituted water shall be accepted by senior appropriators in substitution for water derived by the exercise of their decreed rights pursuant to CRS §37-92-305(5). 53. The change of water right described above will not result in any material injurious affect to the owner or user of any vested water right or decreed conditional water right. 54. Loveland Ready Mix has completed the "first step" necessary to initiate the claimed conditional water rights, has been reasonably diligent since the priority date awarded, and has met all other requirements. The "first step" requires formation of the intent to appropriate, and overt acts that manifest the necessary intent, demonstrate the taking of a substantial step toward application of the water to beneficial use, and provide notice to others of the nature and extent of the claimed appropriation. Criv of Thornton r. City oJ'Fort Collins, 830 P.2d 915 (Colo. 1992). Loveland Ready Mix is thus entitled to the claimed conditional water rights with the priority dates set forth herein. 55. Loveland Ready Mix has established that the claimed conditional water rights, which are the subject of this decree, can be and will be diverted, stored, captured, possessed, and controlled and will be beneficially used and that the subject water rights can and will be completed with diligence and within a reasonable time pursuant to CRS §37- 92-305(9)(b).

Response 8 The deposit to be mined is the Big Thompson River alluvium, which consist of unconsolidated silt, sand, and gravels. The deposit ranges from approximately 25 to 28 feet thick and is overlain by approximately 1 to 2 feet of sandy to clay loam topsoil. Question 9 Describe the proposed use of reclaimed lands and an explanation of the reclamation process, including if any water storage is proposed post -reclamation. Response 9 LRM plans to conduct concurrent reclamation as mining progresses. The reclamation plan includes: • Establishment of a natural/pasture offset along the property boundary • Seeding/vegetating overburden and topsoil stockpiles that will be exposed longer than one year • Implementation of stormwater diversion into mine cells • Backfilling and sloping sides of mining cells with excess topsoil, replacing topsoil • Seeding/vegetating final reclamation areas immediately subsequent to the establishment of reclamation grades • Mitigating impacted wetlands Mining and reclamation are planned in five -acre increments. As soon as practicable after an area is mined, topsoil will be pushed into place to cover disturbed areas slopes. Slopes of 3H:1 V or flatter will be established from 10 feet below the expected water line up to the existing ground surface. Slopes of 2H:1V will be established from 10 feet below the expected water line down to bedrock. Topsoil will be placed over disturbed areas and seeded. The Dunn Pit will be returned to wildlife habitat with groundwater sourced ponds once each of the three phases is completed. 20220509 Mining Questionnaire TELESTO To: Weld County Department of Planning Services Date: May 13, 2022 Page 5 Question 10 Explain and justify any request to operate beyond the standard Mining Operations Policies per Section 23-4-290.A and/or B of the Weld County Code.

What type of sewage disposal system is on the property? If utilizing an existing on -site wastewater treatment system, provide the on -site wastewater treatment permit number. (If there is no on -site wastewater treatment permit due to the age of the existing on -site wastewater treatment system, apply for a on -site wastewater treatment permit through the Department of Public Health and Colorado Office (Corporate) New Mexico Office 750 14th Street SW Loveland, Colorado 80537 970-484-7704 / 970-484-7789 (FAX) 1303 Pope Street Silver City, New Mexico 88061 575-538-5620/575-538-5625 (FAX) To: Lauren Light Date: May 9 2022 Page 2 Environment prior to submitting this application.) If a new on -site wastewater treatment system will be installed, please state "a new on -site wastewater treatment system is proposed." (Only propose portable toilets if the use is consistent with the Department of Public Health and Environment's portable toilet policy.). Response 2 No existing sewage disposal system exists on site. LRM will provide a contracted port -a - john for use by its equipment operators and truck drivers. Question 3 If storage or warehousing is proposed, what type of items will be stored? Response 3 No storage or warehousing is proposed with the project. Question 4 Describe where and how storage and/or stockpile of wastes, chemicals, and/or petroleum will occur on this site. Response 4 Wastes, chemicals, or petroleum will not be stored on -site. Question 5 If there will be fuel storage on site, indicate the gallons and the secondary containment. State the number of tanks and gallons per tank. Response 5 There will be no fuel storage on -site. However, LRM will store an excavator, front end loader and small water truck on site. Question 6 If there will be washing of vehicles or equipment on site, indicate how the wash water will be contained. 20220509 EnvironmentalHealthQuestionnaire TELESTO To: Lauren Light Date: May 9 2022 Page 3 Response 6 There will be no washing of vehicles or equipment on -site. Question 7 If there will be floor drains, indicate how the fluids will be contained. Response 7 There will not be any floor drains. Question 8 Indicate if there will be any air emissions (e.g. painting, oil storage, etc.). Response 8 Possible air emissions include dust from the gravel haul roads and exhaust from the excavator or haul trucks. A Dust Abatement Plan is included with submittal and a Mining Operations APEN (Form APCD-222) has been submitted to CDPHE (dated 10/21/21). Excavation will create little to no dust as the project is using wet -mining techniques. No processing will be conducted on site. Question 9 Provide a design and operations plan if applicable (e.g. composting, landfills, etc.). Response 9 A design and operations plan is not applicable to this project. Question 10 Provide a nuisance management plan if applicable (e.g. dairies, feedlots, etc.). Response 10 Because LRM will mine the site wet, they expect dust to be minimal. They will institute watering of the internal haul roads to also limit dust generation from hauling of materials. Noise is always a potential nuisance to neighbors. LRM performed a baseline noise study to project potential impacts and devise mitigation measures if necessary. 20220509 EnvironmentalHealthQuestionnaire TELESTO To: Lauren Light Date: May 9 2022 Page 4 A separate nuisance management plan is not applicable to this project. Question 11 Additional information may be requested depending on type of land use requested. Response 11 LRM notes this comment and looks forward to working with the County.
