Exhibit C, Sheet 2: The oil and gas -constrained plan avoids impacts with existing oil and gas facilities. A number of existing facilities are non -producing andior subject to rights assigned to the Operator/Applicant. Any facility that is controlled by the Operator may be removed or relocated according to applicable agreements and regulations. • Exhibit C, Sheet 3: The full recovery plan shows raining and reclamation scenarios where all current oil and gas facilities are removed or relocated, minimizing the linear run of slideslopes and consequently the surface area of future reservoir banks. It is anticipated that each incremental removal or relocation of oil and gas equipment will reduce reclamation liability, and the Operator may therefore request an associated reduction in financial warranty. Bonding under Exhibit L is based on the higher financial liability amount associated with oil and gas -constrained recovery. (a) Description of the method(s) of mining to be employed in each stage of the operation as related to any surface disturbance on affected lands{ The peen it area includes a significant deposit of sand and gravel located in the alluvium of the Saint Drain River in Weld County. The site is located south of Highway 66, west of Weld County road 19, north of Weld County Road 28 and east of Weld County Road 17. It encompasses 307.2 acres and consists of two cells (cell 2 and 3), a silt pond and a freshwater pond. Site Preparation. Initial disturbance of the property will include: stripping the topsoil and overburden material, constructing the slurry walls. ,Fining'. Scrapers will strip the topsoil and overburden material from a given phase and place stockpiles in the processing area. Any excess material not needed for reclamation may be sold or hauled off -site during the life of the mine. There will be no mining below the grounchtvater table u& the s urrgall is corn fete, tested and aDoroved. Each phase will be dry -mined using scrapers, bulldozers, front-end loaders, excavators, or similar equipment. The mining in the site will progress in 4 stages, Stage 1 will establish the siltation and freshwater ponds in the southwest corner of the site. Stage I will open up approximately 27 acres and will be reclaimed last. Stage 2 though stage 4, ranging in size from 41 to 75 acres, will start in the northeast corner and will proceed southwest ending in Cell 7. The operator will develop and comply with a Stormwater Management Plan and Spill, Prevention, Control and Countermeasures Plan. The operator will notify the Division of Reclamation and Mine Safety and in the event of a reportable spill. Nix — Gravel Mine — MLRB 112 Permit Amendment Exhibit D - 1 Processlr q: The material will be dry screened or not screened at all and transported offsite by truck. The processing area will be located on the south side of the site in cell 2. Import Ma teriat The operator may import material from and export material to other sites. The applicant is aware that in accordance with Rule 3.1,5(9) of the Construction Material Rules and Reguiations, if any offsite material is used as backfill, a notarized letter will be submitted to the Division indicating the materials are inert. The applicant will supply such a letter to the Division if, at the time of Reclamation, the applicant intends to use off -site material as backfll. (b) Eartbrrroving; Topsoil and overburden will be stripped with scrapers or bulldozers and stockpiled in segregated piles at the edge of the active mine phase. Excavators, front-end loaders, and bulldozers will be used to excavate the material. Haul trucks will be utilized to transport the raw material from the active mine phase to the processing area, See Exhibit C for a cross- section of side -slope mining; after recovering to near -vertical at an offset or 1;1 setback to the planned top -of -slope, overburden, recovered silt or other suitable fill will be replaced to establish the final slope profile. (c) Ali grater diversions and impoundments; Storm water will be discharged per a C DPHE discharge permit. There are no planned diversions or impoundments of existing water bodies. A wash cycle for the aggregate processing area will be established using the freshwater pond as a source and the silt pond for return flog, with natural groundwater filtration between the source pond and the return pond. Any water consumed will be provided by the existing water rights associated with the property and/or a groundwater well with associated substitute water supply plan (see Exhibit G). (d) The size of area(s) to be worked at any one time. Excluding the processing area, the maximum area to be worked on at any one time is approximately 30 acres. (e) An approximate timetable to describe the mining operation. The timetable is for the purpose of establishing the relationship between mining and reclamation during the different phases of a mining operation. The Operator anticipates that mining will commence as soon as all permits are in place. The Operator anticipates extracting approximately 1,000,000 tons of aggregate in a typical year, up to 1.7 miklion tons at peak capacity. Production rate will vary based on market demands. Timetable For PolTh ng and Reclamation Stage 1(Freshwater and silt ponds): The Operator will wet mine the freshwater and silt ponds. Mining will begin in the siltation pond and progress west to the freshwater pond. The average rate of mining is expected to be between 1,000,000 tons per year and 1,500,000 tons per year. Given these rates it is expected that mining in Stage I will take approximately 1 to 1 % years. Nix — Gravel mine — MLRB 112 Permit Amendment Exhibit D - 2 Page 12 of 123 The freshwater and siltation ponds will remain open during the life of the mine and will be reclaimed following the cessation of mining at the site. Stage 2(Ceit 3): Mining will begin in the southwest corner of the cell by the Nix house and proceed counter clockwise around the oil and gas facilities. Assuming the same raining rates as Stage 1, Stage 2 is expected to take 4 to 5'/2 years. Stage 3(Ceil 4): lining will begin in the north and progress south. It should take approximately 3 to 4 years. Stage 4(Cells 5, 6, & 7): Mining will start in the north of Cell 5 and will continue clockwise to end at the west end on Cell 7. Mining in this stage should take approximately 3 % to 5 Reclamation will begin after mining is complete. Following the completion of each stage, excepting stage I, reclamation of that stage will begin concurrent with mining of the subsequent stage. Upon completion of Stage 4, Stage I will begin reclamation. Please refer to the dining Plan Map in Exhibit C for phase areas to be mined, locations and areas. Use Mining Plan Map in conjunction with narrative to present: (I.) Nature, depth and thickness of the deposit and thickness and type of overburden to be removed The overburden at the site typically consists of two sub -units; a su rficial brown clayey to silty sand that overlies a buff silty sand. These sub -units are described below. u racial brown clayey to silty sand with local sandy clay: The su rficial brown clayey to silty sand sub -unit is typically approximately 1 to 2 feet in thickness but locally is as thick as 8 feet. This sub -unit is usually slightly moist to moist, medium dense to dense with the top 6 to 8 inches containing significant organics. Of the samples tested, the percent passing the No. 200 sieve ranged from 16.6% to 74.7/0. Atterberg Limits testing resulted in Liquid Limits of 19 to 31 and Plasticity Indices of 3 to 11. Buff silty sand: The brown surficial sub -unit is underlain by the buff silty sand sub -unit. The buff silty sand sub -unit ranges from approximately 4 to 14 feet thick and is slightly moist to moist becoming wet at the water table. The silty sand is very loose to medium dense and locally becomes clayey with depth. Of the samples tested, the percent passing the No. 200 siege ranged from 10.9% to 39.1%. Atterbe rg Limits testing indicated the material was granular non -plastic. The sand and gravel is present throughout the site underlying the overburden and overlying the bedrock. This unit typically consists of gravelly, f n e to coarse grained sand locally grading to sandy gravel. Where gravels were encountered, the size was typically 1/4 to 2 inches. This unit is typically medium dense to dense, but is also locally very loose to loose. This deposit ranges in thickness from approximately 26 feet to 60 feet. The sands are clean with fines content (silt and clay) generally ranging from approximately 2.0 to 4,1 percent averaging 3.0 percent (Big Rock Exploration, 2019). Local clay lenses were reported within the deposit by Big Rock Exploration (2019). (ii.) {nature of the stratum immediately beneath the material to be mired in sedimentary deposits Nix — Gravel Mine — MLRB 112 Permit Amendment Exhibit a- 3 Page 13 of 123 The bedrock encountered in the exploratory borings was generally weathered in the upper one to two feet typically became harder in unweathered bones. The bedrock consisted of silty: fine to medium grained, sandstone with local claystone seams. For the sandstone samples, the percent passing the minus No. 200 siege ranges from approximately 13.4% to 26.7% averaging 21.6%. For the cl aystone seams, the percent passing the No. Zoo siege ranges from approximately 53.3% to 74.1% averaging 64.5%. Identify the primary and secondaty commodities to be mined/extracted and describe the intended use. The primary commodities are sand, gravel and fill; intended for construction materials. Marne and describe the intended use of all expected incidental products to be mimed/extracted by the proposed operation. Gold may be extracted as an adjunct component of any wash equipment installed at the site. Specify if explosives will be used in conjunction with the mining (or reclamation) No explosive material will be used on -site. Specify the dimensions of any existing or proposed roads that will be used for the mining operation. Describe any improvements necessary on existing roads and the specifications to be used in the construction of new roads. New or improved roads must be included as part of the affected lands and permitted acreage. Affected land shall not include offnsile roads which existed prior to the date on which notice was given or permit application was made to the office and which were constructed for purposes unrelated to the proposed mining operation and which will not be substantially upgrades to support the mining operation. Describe any assocated drainage and runoff conveyance structures to include sufficient information to evaluate structure sizing. The affected land and permitted acreage is inclusive of over one and one-half miles of land directly abutting public roadways; there is no need for any additional driveways, and ors -site haul roads will be incidential to mining areas depicted on the dining Flan iVIap. No roadways are affected by the mining operation other than access roads within the permit boundary and existing public roads to the site. The Operator updated in the Weld County Access permit for the site (AP21-00023) in January 2021, Nix — Gravel Mine — M LIMB 112 Permit Amendment Exhibit a - 4 Page 14 of 123 EXHIBIT E - RECLAMATION PLAN This information provided in this Exhibit is intended to satisfy the requirements outlined in Section 6 . 4. 5 of the Colorado Mined Land Reclamation Board Construction Material Rules and Regulations: The proposed mining and reclamation plan focuses on minimizing the ecological impacts of mining , minimizing the length of time of impact, and maximizing long -term benefits . (a) A description of the type(s) of reclamation the operator proposes to achieve in the reclamation of the affected land, why each was chosen, the amount of acreage accorded to each, and a general discussion of methods of reclamation as related to the mechanics of earthmoving; The mined area in Cell 2 and 3 will be reclaimed to a lined water storage reservoir due to a need within the state for water storage facilities. The mined area in the silt and freshwater ponds may be backfilled and used in support of the reservoir facility or may be converted to a water storage facility if sufficient void space exists at the completion of mining . Refer to Exhibit F for the acreages and additional details . Earthrnovinci The topsoil may be replaced by a scraper or haul truck, excavator and dozer and generally graded with a blade. All grading will be done in a manner that controls erosion and siltation of the affected lands, to protect areas outside the affected land from slides and other damage . In addition , all backfilling and grading will be completed as soon as feasible after the mining process . All disturbed areas will be regraded and smoothed to a finished grade that is suitable for revegetation or the final land use . As noted previously, the area will be reclaimed as mining proceeds . Finish grading , topsoil placement and seeding will occur throughout the life of the mine. Once the resource is completely removed , final grading and vegetation of the slopes will be completed . The empty vessel will be available for water storage . A typical cross-section of the shoreline is included on the Reclamation Plan Map . (b) A comparison of the proposed post-mining land use to other land uses in the vicinity and to adopted state and local land use plans and programs. The water storage reservoirs will be compatible with the other land uses in the vicinity, which includes farmland , industrial land , and rural residential . Municipal boundaries have approached the vicinity of the site and represent a growing need for both construction materials and water storage facilities. (c) A description of how the Reclamation Plan will be implemented to meet each applicable requirement of Section 3. 1. The Operator will carry reclamation to completion with reasonable diligence . Each phase of reclamation will be generally completed within one to two years from completion of Nix - Gravel Mine - MLRB 112 Permit Application Exhibit E - 1 Page 15 of 123 mining , but not more than five years from the date the operator informs the Board or Office that final reclamation has commenced . Section 3. 14 Reclamation Measures Material Handling: Grading will be performed to help control erosion and siltation of the affected lands through phased mining , implementing good operation techniques to handle material as little as possible , and vegetation of stockpiles remaining in place for more than one growing season . Although the use of erosion protection devices is not anticipated , if deemed necessary by the operator at the time of excavation , silt fence, haybale e dams or other erosion control devices will be installed . Backfilling and grading will be completed as soon as feasible after the mining process is complete for each phase. Maximum slopes and slope combinations will be compatible with the configuration of surrounding conditions and selected land use . Mining will occur at a slope that is stable. Reclaimed slopes in the water storage reservoir will not be steeper than a 3 : 1 ratio. The upland area will be reclaimed to grades consistent with pre-mining drainage patterns. The operator will backfill using fill material generated on-site , or imported inert fill generated outside the permit area . If any inert off-sae material is used as backfill , a notarized letter will be submitted to the Division as required by Section 3 . 1 .5(9) of the MLRB Construction Material Rules and Regulations . It is not anticipated that mining will uncover any refuse or acid-forming or toxic producing materials, however if any such materials are encountered the operator will take precaution to handle the materials in a manner that will control unsightliness and protect the drainage system . Drill or auger holes that are part of the mining operation shall be plugged with non- combustible material , which shall prevent harmful or polluting drainage . Any test pits, soils boring holes , or monitoring wells not located within the mine excavation limits will be plugged as soon as it can be confirmed that they are no longer needed for the operation . Mined material to be disposed of within the affected area will be handled in such a manner so as to prevent any unauthorized release of pollutants to the surface drainage system . No unauthorized release of pollutants to groundwater shall occur from any materials mined , handled or disposed of within the permit area Section 3. 1. 6 Water-General Requirements : The Operator will comply with applicable Colorado water laws governing injury to existing water rights and with applicable state and federal water quality and dredge and fill laws and regulations . The operator will develop and comply with a stormwater management plan and will use best management practices (BMPs) to ensure groundwater and surface water are protected to the greatest possible extent. BMPs include schedules of activities , Nix - Gravel Mine — MLRB 112 Permit Application Exhibit E - 2 Page 15 of 123 prohibitions of practices, maintenance procedures and other management practices to prevent or reduce the pollution in runoff from the site. Section 3.1.7 Groundwater ! Specific Requirements: The Operator will comply with the applicable standards and conditions for classified and unclassified groundwater. Section 3.1.8 Wildlife: The miring and reclamation plans have been designed to account for the safety and protection of wildlife on the mine site. The Operator will mine the site in phases and use concurrent reclamation methods to minimize the impact on wildlife, The proposed reclamation plan may improve wildlife habitat, The proposed seed mix and plantings will create improved carer, foraging, roosting, and nesting areas for wildlife. The water area within the reservoir will serve as habitat for waterfowl and other bird species and the fringes of the reservoir will be used by mammal, bird, reptile and amphibian species. Control and/or removal of noxious and weedy species during the project and the introduction of desirable gram i not d a forb and potential goody species during reclamation will result in enhancement of wildlife habitat on the project site. Section 3. 1.9 . 9 Topsoilirrg: Topsoil shall be removed and segregated from other spoil. Topsoil stockpiles shall be stored in places and configurations to minimize erosion and located in areas where disturbance by ongoing mining operations will be minimized, Once stockpiled, topsoil shall be re -handled as little as possible. Stockpiles that will remain in place for more than one growing season will receive vegetative corer. Section 3.1.10 Revege tabor : In those areas where revegetation is part of the reclamation plan, the land shall be revegetated in a manner that establishes a diverse, effective, and long-lasting vegetative corer that is capable of self -regeneration without continued dependence on irrigation or fertilizer and is at least equal in extent of cover to the natural vegetation of the surrounding area. These areas are relatively minimal given the water development reclamation plan for the site. The proposed seed -mix and plantings for reclamation are outlined on the Reclamation Plan included in Exhibit F of this application. Section 3.1.11 Buildings and Structures: : Please refer to the enclosed Reclamation Plan included in Exhibit F. Section 3,1.12 Signs and Markers The Operator will past appropriate signage at the entrance to the mine site. The permit area will be marked by existing fencing, or proximity to existing County roads. Nix - Gravel Mine = M LRB 112 Permit Application Exhibit E - 3 Page 17 of 123 (d) Plans for topsoil segregation, preservation and replacement; for stabilization, compaction and grading of spoil and for revegetation. Topsoil will be removed and segregated from other spoil. Topsoil not needed for reclamation may be sold or removed from the site. For reclamation, topsoil will be replaced by a scraper and generally graded with a blade. Grading shall be done in a manner that controls erasion and siltation of the affected land and protects areas outside the affected land from slides and other damage. In addition, backfilling and grading shall be completed as soon as feasible after the mining process. Final grading vwrill create a final topography that is appropriate for the final land use. For example, final grading of the reservoir above the high grater line will replace material no steeper than 3:1 slope to meet the grade at the top of the banks. Topsoil will be uniformly placed and spread an areas disturbed by the mining, above the anticipated high grater line. The minimum thickness shall be 6 inches above the surrounding finished grade. The topsoil shall be keyed to the underlying and surrounding material by the use of harrows, rollers or other equipment suitable for the purpose, In those areas where revegetation is part of the reclamation plan, the Operator will revegetate the land in such a manner so as to establish a diverse, effective, and long- lasting vegetative cover that is capable of self -regeneration without continued dependence on irrigation or fertilizer and is at least equal in extent of cover to the natural vegetation of the surrounding area. Seed will be drilled and mulched. The revegetation seeding and plant list on the Declamation Plan Map contains the preferred species of grasses, shrubs and trees to be planted. Seeding will tape place once final grading and replacement of topsoil have been completed for each phase. Timing of seeding will be consistent with standard horticultural practice for dryland applications - generally between late September and the middle of April to ensure there is adequate moisture for germination. fie) A plan or schedule indicating how and when reclamation will be implemented. include: I. An estimate of the periods of time which will be required for the various stages or phases of reclamation. Reclamation for any given stage of mining may take up to five years to allow for successful revegetation. Please refer to the Timetable for {dining and Declamation in Section (e) of Exhibit D. H.

Seeding — types, mixtures, quantities and time of application; Please refer to the Reclamation Plan Map for the list of plant materials and seeds to be utilized. The operator will seed during the appropriate season to ensure adequate moisture for germination and implement geed controls to allow the gasses to successfully establish. Additional plantings may be installed once the reservoirs are full of grater and the gasses are established. iii. Fertilization - types, mixtures, quantities, and time of application; The type and application rate of fertilizer shall be determined based on a soil test at the time of final reclamation. iv. Revegetotion - types of trees, shrubs, etc.; Please refer to the Reclamation Plan daps for the types, quantities and location of plantings. Trees and shrubs are generally avoided in the design of reservoir facilities to avoid root system breach of slurry walls. Moody plantings during the life of mine will be determined in review of the local zoning permit. v. Topsoiling - specify anticipated minimum depth or range of depths for those areas where topsoil will be replaced, Topsoil will be uniformly placed and spread on all areas disturbed by the mining above the anticipated high water line. The minimum thickness shall be 6 inches above the surrounding finished grade, WEED MANAGEMENT PLAN The Operator will monitor and control noxious greeds as they appear. The Operator typically prefers to control weeds mechanically, by mooring and/or disoing. If necessary, weeds will be killed with a contact herbicide.

Please refer to Exhibit C for locations of water courses in close proximity to the site, including wells, springs , stock water ponds, reservoirs and ditches. (b) identify all known aquifers The site is underlain by a shallow alluvial aquifer, typical of its position upgradient of the St. Vrain River. (c) Show how water from dewatering operations or runoff from disturbed areas, piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater both during and after the operation. Please refer to the Mining Plan Map in Exhibit C of this application . Dewatering operations will run continuously during the mining of the freshwater and silt ponds , then intermittently during mining within the slurry walled cells. Dewatering water will be pumped to the discharge pits shown on Exhibit C . Mine areas will drain internally. Uncontrolled releases of surface water in disturbed areas will not occur. Stormwater collected in the active mine area will be managed through the dewatering system . The operator will apply for a Colorado Department of Public Health and Environment Discharge permit and will maintain a Storrnwater Management Plan and Spill Prevention Control and Countermeasure Plan . (d) Estimate project water requirements including flow rates and annual volumes for the development, mining and reclamation phases of the project. Water needs estimated below provide for sustained production as detailed in the Mining Plan . The Operator will adjust water supplies to account for actual demand , avoid waste, and continuously comply with laws and regulations of the Division of Water Resources and any other water agency having jurisdiction over the operation . Projected Use And Consumption: Annual evaporative depletions will be the evaporation from up to 5000 feet of 4-foot wide de-watering trench , located inside of the slurry wall . The total area of exposed water is 0 . 5 acres. The gross annual evaporation at the Nix Gravel Mine aggregate mine is 42 inches according to NOAA Technical Report NVVS 33 , EvaDoratior Atlas for the Contiguous 8 United States. Monthly evaporative losses are determined using percentages specified by the State Engineer's Office for locations below 6 , 300 feet. The nearest weather station is in Longmont where the average annual precipitation is 15 . 08 . Effective precipitation , that part of historical precipitation which was consumed by native vegetation on land to be covered by water surface , is conservatively estimated to be 70 percent of the total precipitation . The annual average effective Ready Mixed Concrete Company - Nix Gravel Mine — MLRB 112 Permit Application Exhibit G - 1 Page 23 of 123 precipitation at the property is estimated to be 9.09 inches. When subtracting the effective precipitation from the gross evaporation yields, the net annual evaporation is 32.13 inches, or 2.68 acre-feet per acre. The annual amount of evaporation from open water surfaces is 1.34 acre-feet. Mining Production & Operations: The operator expects to extract up to 1.7 million tons annually of aggregate material from the site. All water retained in the recovered material will be replaced pursuant to the Substitute Water Suppler Plan (SWSP). The total annual amount of crater retained in the gravel product from alining activities totals in a maximum of 23.1 acre-feet. The SWSP is renewed annually and will reflect analysis of production and depletion anticipated in each year of operation. In addition, an estimated 4.0 acre-feet of water per year will be used for dust control based (approximately) on 5,900 gallons per day, 5 days a week for 10 months. Annually the total evaporative and operational losses from mining activities (open grater surface evaporation, water retained in the aggregate product, dust suppression) totals 28.4 cre-feet of depletion which must be augmented. All depletions were lagged to the Saint Vrain River using the lagging factors approved by the State Engineer pursuant to on -going Substitute Water Supply (SWSP) approvals. (e) Indicate the projected amounts of the grater sources to supply project water requirements Replacement Water The source of replacement water for depletions will be that portion of the operator's Last Chance Ditch Company shares, to compensate for depletions, or the operator may lease available water in the St. Vrain River system, The State Engineer must approve a SWSP every year, providing annually or more frequently the opportunity to review the sufficiency of grater supplies. These approvals require that the applicant provide a detailed explanation of the mining operations, a quantification of all mining activities and subsequent depletions and all legally available replacement sources. (t) Affirmatively stale that the Applicant has acquired or applied for a National Pollutant Discharge Elimination System permit from the water Quality Control Division The operator will apply for a National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division of the Colorado Department of Public Health and Environment prior to discharging grater from the site, Ready Mixed Concrete Company - Nix Gravel Mine Exhibit G - 2 MLRB 112 Permit Application Page 24 of 123 EXHIBIT H - WILDLIFE INFORMATION The information provided in this Exhibit is intended to satisfy the requirements outlined in Section 6.4 .8 8 of the Colorado Mined Lend Reclamation Board Construction Material Rules and Regulations: (?)

Nix - Gravel Mire — MLRB 112 Permit Amendment Application Exhibit H - 1 Page 25 of 123 6.4.$ Exhibit H - Wildlife Information Wildlife Assessment Site Description Savage and Savage conducted an on -site wildlife assessment for the Ready Mixed Concrete Nix arnnendment project site on March 1, 2020. The Nix amendment site is comprised of approximately 307 acres within portions of Section 28 within Township 3 North, Range 67 West of the 6th 'rime Meridian, 'field County, Colorado. The center of the project site is located at 40.196699' latitude and -104.893068° longitude. The property is located west of Platteville between Weld County Roads 19 and 17, immediately south ofColorado State Highway 6. The property is accessed from Weld County Road 19. Weather during our site investigation was cool, and overcast with a temperature in the mid - 401s (`gyp'). The topography of the site is dominated by the primary alluvial terrace of the St, rain River. The elevation of the project area. averages 4805 feet and slopes gently to the northwest toward the St. Vrain River, Topography and Geomorphic .features The Nix amendment site is located on the primary alluvial terrace of the St, Frain River, approximately 2300 feet east-southeast of the current river channel. The topography of the property is largely flat and dominated by flood irrigated agricultural fields and associated irrigation canals and ditches. Hydrology The most significant regional hydrologic feature is the St. Vrain leer to the northwest of the site. The Seep Drainage Ditch flows from south to north along west boundary of the site. A number of inigation lateral ditches and several tailwater drainage ditches distribute irrigation water and drain the agricultural fields within the Nix amendment site as well as agricultural fields to the south and. east. Tailwater eventually exits the site under Colorado Highway 6 and drains to the St. Vrain River. Soils The soils that dominate the site are formed from alluvium and consist ofloams, clays, and. sands (USDA, 1981). Vegetation Vegetation of the project site can be divided into native and agricultural communities. Native vegetation is restricted to the tailwater ditches that adjoin the agricultural fields. This vegetation community contains stands of cattail (Typha la ti a li a), reed. canarygrass (Phalaris arundinace ), inland saltgrass (Distichlis spicata), rushes Gruncus sp.), and Exhibit H Page 1 Page 26 of 123 scattered coyote willows (Salty exi a). The remainder of the site contains seasonal fled irrigated agricultural cropland. Land Uses Adjacent land uses include aggregate mining, livestock grazing, and agriculture. Significant Wildlife Resources Tables 1, 2, and 3 list wildlife species that potentially occur on -site according to the Colorado Distribution Latilong Studies (CDOW, 1981, 1990, 1998). The latilong studies address vertebrates in the categories of mammals, birds, and reptiles and amphibians.. During the site investigation few wildlife species were observed. No mamm.al species were directly observed during the site investigation, though deer and raccoon tracks were observed alongside irrigation. ditches during our inspection. Canada geese (Branta canadensis) were observed flying over adjacent fields. No reptiles or amphibians were observed during the on -site investigation. further review of wildlife species for which the Colorado Division of larks and Wildlife has distribution maps on the Colorado Oil and Gas Conservation Commission web site 014 ://cogcc. state.o.use'infos siMapsi ildlif'emap.cfm) identified sensitive wildlife .habitat and surface restricted occupancy areas related to bald eagle nests northwest of the project site along the St. Vrain River (see appended map). Seasonal Use The open nature of ` the site (agricultural crops) with the attendant lack of cover limits the uses of the site by the majority of wildlife species. Opportunistic use by rodents, raccoons, coyotes, foxes, and deer likely occurs when agricultural crops are tall during the summer growing season, and wildlife species opportunistically utilize the irrigation and tailwater ditches within the site, with the exception of bats (identified from the list of potentially occurring species), the mammals species encountered during the site inspection or that potentially occur on -site are expected to be year-round residents or users of the site. The carnivore and ungulate species are not restricted to this site and tend to have relatively large home ranges up to several square miles). The majority of rodent and insectivore species can be expected to reside on -site throughout the year, though many may hibernate during the cold months. Avian species may be year-round, temporary migrants, or summer residents of the site. Year-round residents would include raptors, ,gallina.ceous birds, pigeons, owls, and woodpeckers. The majority of the passerines would use the site during the spring, summer, and fall for feeding or resting during migration. Amphibian and reptile species of the site are summer residents within the tailwater ditches when water is present. Exhibit H Page 2 Page 27 of 123 Threatened .and Enda►ngere-d Species and Critical Habitat Of the federally listed threatened or endangered species for the State of Colorado, the U.S. Fish and Wildlife Service (USFWS) has expressed an interest in two that may potentially be present in the project site or adjacent area; the Preble's meadow jumping mouse (Zapus u son spreblei), and the lite Ladies -tresses orchid s irant es d'iluvialis). Additionally, while not listed under the Endangered Species Act, bald. eagle (Haliaeetus leucocephalus) nesting and winter roosting sites are of concern, and regulated b, the UFW. Preble's meadow jumping mouse Characteristic habitat for the Preble's meadow jumping mouse occurs below 7400 feet elevation within the South Platte River 100 -year floodplain, tributes, and associated wet meadow complexes (from the Front Range to Ft. Morgan, Colorado) in Adams, Arapahoe, Denver, Elbert, Larim er, Morgan, and weld counties. The USFWS has described the characteristic habitat of the mouse as areas with the following features; low undergrowth with ,grasses and forb s, in open wet meadows and riparian corridors or where tall shrubs and low trees provide cover. The mouse prefers mesic to h dric lowlands, and has been found in agricultural and native landscapes, along irrigation canals, and natural drainages, as well as yeas dominated by both introduced and native plant species. Preble's meadow jumping mouse characteristic habitat is net present at the Nix amendment site, as the site lacks the stratified vegetation of mouse habitat and contains monocultures of reed eanarygrass and cattails. Savage and Savage conducted a Preble's meadow jumping mouse survey immediately north of the Nix amendment site adjacent to the St. rain liver in 1999 and found 11O Preble's individuals. Additionally, in 2001, U FWS concurred with a Savage and Savage request for disqualification of the Nix site (USDI, 2001), agreeing that "Preble's habitat is not present in the subject area.. to Ladies -tresses orchid The The ladies -tresses orchid (Spiranthes diluvialis) is a federally listed threatened plant species characteristically found in wet meadows and alluvial flood plains below 6500 feet in northern Colorado, southwestern Wyoming, and the Uintah Basin of Utah. Characteristic orchid habitat is described as relatively low ,elevation riparian, spring, and lakeside wetland meadows. The Nix amendment site does not contain characteristic Ute ladies' -tresses orchid habitat. In 2002, USFWS concurred with a Savage and Savage request for disqualification of the Nix site (USDI, 2002), agreeing that "suitable habitat for S. diluvialis is not present in the areas assessed." Exhibit H Page 3 Page 28 of 123 Bald Eagles The Colorado Oil and Gas Conservation Commission through the Colorado Division of Parrs and Wildlife has compiled bald eagle nests and winter night roost locations on their state mapping application (COGCC, 020). Based on a review of this resource (map attached), there are two bald eagle nests (comprising restricted surface occupancy and sensitive Wildlife habitat) .northwest of the Nix amendment site. Operations at the site are outside setbacks established by the Colorado Division of Parks and. Wildlife, therefore, there should be no impacts to nesting eagles from the project. Project Effects to Wildlife The Nix amendment site is proposed for mineral (sand and gravel) extraction activities. Noise and air emissions during mining gill cause a temporary disturbance to wildlife. Species such as raccoons, coyotes, beaver, deer, and raptors will continue to use the riparian conidor during mining operations and the site itself when operations are not active. Bird species will use the p+el.phery of the site and the site itself opportunistically, if prey or food species are present. The proposed project will extract material and leave two slum wall lined water storage cells within the site. The mining and reclamation plan will create open water wildlife habitat that is currently not present.Areas of open water will sustain additional species of reptiles and amphibians as well as shorebirds and waterfowl. The addition of the water will create fringe environments favorable to predatory mammals and raptors, as well as food and water sources for herbivores, with revegetation of the borders around the water storage cells, additional strata and vegetation layers will be added to the site,, creating improved cover, foraging, roosting, and nesting areas for wildlife.

This letter describes the project and slope stability analyses utilized to evaluate the minimum distance between the edge of mining and adjacent structures to avoid damage to the structure. The site is located at the southwest corner of the intersection of State Highway 66 and Weld County Road 19 , approximately 3.3 miles west of the town of Platteville , Colorado . More specifically , the mine is within part of Section 28 , Township 3 North , Range 67 West of the 6th, Principal Meridian . The site is 0 . 6 miles east of the Saint Vrain River in an area of agricultural land with common oil and gas wells and related infrastructure. The mine plan is shown on Figure 1 . The site will be mined in three cells located on the southwest (Cell 1 ), south central (Cell 2) and the northeast (Cell 3) parts of the site. The Cells 2 and 3 will be lined with soil-bentonite slurry walls and will be reclaimed as below grade reservoirs. Cell 1 will receive wash fines from the processing of mined sand and gravel. Based on the stability analyses, this report indicates that the setbacks and perimeter slopes in the mining plan are sufficient to protect structures within 200 feet of the permitted mining boundary. Actual setbacks may be greater due to permit limitations, zoning requirements , construction issues, agreements with owners, and extent of economically mineable aggregate or other issues . GEOLOGY The Site is located approximately 20 miles east of the eastern flank of the Rocky Mountain Front Range. Younger sedimentary strata dip eastward off the Pre-Cambrian igneous and metamorphic rocks that form the core of the Front Range into the Denver Structural Basin . The Denver Basin is an asymmetrical downwarp of sedimentary strata with a steeply dipping west limb and a gently dipping east limb. Bedrock does not crop out at the site , however regional geologic mapping of the area (Colton , 1978) indicates the near surface bedrock at the site is most likely either the Fox Hills Sandstone and/or the Laramie Formation . Colton (1978) describes the Fox Hills Sandstone as cross bedded sandstone that grades downward to a fine grained silty sandstone interbedded with gray fissle shale. Colton (1978) describes the Laramie as mostly claystone, shale , sandy shale , and lenticular sandstone with common coal beds in its lower section . The regional mapping indicates the bedrock is overlain by the Piney Creek and Broadway Alluviums . The Piney Creek is mapped over most of the site . The Broadway is mapped on the southeast part of the site . Colton (1978) describes these alluvial deposits as sandy to gravelly alluvium. The Piney Creek Alluvium is usually covered in flood waters . The Broadway Alluvium forms the adjacent higher terrace that is typically 20 to 40 feet above major streams. GEOTECHNICAL CONDITIONS Based on the site investigations , the natural site stratigraphy phy generally consists of three main units: 1 ) Overburden generally consisting of clayey and silty sands; 2) sand and gravel alluvial deposits that underlie the overburden and Page 62 of 123 Mr. Joe Lamanrra January 14, 2020 Page 2 overlie the bedrock; and 3) bedrock usually consisting of sandstone with local areas of claystone , These units are described in more detail below. 3. 5. 1 Overburden Unit The overburden at the site typically consists of two sub-units; a surficial brown clayey to silty sand that overlies a buff silty sand . These sub-units are described below. Svrficfal brown clayey to silty sand with local sandy clay. The surficial brown clayey to silty sand sub-unit is typically approximately I to 2 feet in thickness but locally is as thick as 8 feet. This sub-unit is usually slightly moist to moist, medium dense to dense with the top 6 to 8 inches containing significant organics . Of the samples tested , the percent passing the No. 200 sieve ranged from 16 , 6% to 74.7% . Atterberg Limits testing resulted in Liquid Limits of 19 to 31 and Plasticity Indices of 3 to 11 . Buff silty sand: The brown surficial sub-unit is underlain by the buff silty sand sub-unit. The buff silty sand sub- unit ranges from approximately 4 to 14 feet thick and is slightly moist to moist becoming wet at the water table. The silty sand is very loose to medium dense and locally becomes clayey with depth , of the samples tested , the percent passing the No. 200 sieve ranged from 10.9 % to 39. 1 % . Atterberg Limits testing indicated the material was granular non-plastic. 3. 5. 2 Sand & Grave/ Unit The sand and gravel is present throughout the site underlying the overburden and overlying the bedrock. This unit typically consists of gravelly, fine to coarse grained sand locally grading to sandy gravel . Where gravels were encountered , the size was typically 1/4 to 2 inches. This unit is typically medium dense to dense, but is also locally very loose to loose . This deposit ranges in thickness from approximately 26 feet to 60 feet. The sands are clean with fines content (silt and clay) generally ranging from approximately 2.0 to 4. 1 percent averaging 3 .0 percent (Big Rock Exploration , 2019) . Local clay lenses were reported within the deposit by Big Rock Exploration (2019). 3. 5. 3 Bedrock The bedrock encountered in the exploratory borings was generally weathered in the upper one to two feet typically became harder in unweathered zones , The bedrock consisted of silty, fine to medium grained , sandstone with local claystone seams. For the sandstone samples, the percent passing the minus No. 200 sieve ranges from approximately 13 .4% to 2647% averaging 21 .6 %. For the claystone seams, the percent passing the No. 200 sieve ranges from approximately 53.3% to 74. 1 % averaging 64, 5%. The approximate top of bedrock contours are presented on Sheet 4 of the plans. 3.5. 4 Groundwater Groundwater was encountered in all of the borings at approximately 7 to 12 feet below ground surface . The groundwater levels will vary seasonally and will typically rise during the irrigation season . Groundwater will be controlled with the proposed below grade slurry wall . After slurry wall construction , groundwater mounding is anticipated on the upgradient (west and south) side of the site and a groundwater shadow (deeper water table) is anticipated on the downgradient (north and east) side the site. From a geotechnical standpoint, the sand and gravel will form the majority of the mine slopes. These soils are generally strong and stable , particularly when dewatered. Dry mining is planned as the slurry wall will control water revel in the main cell and mining will be above the water table in the other cell .

STABILITY ANALYSES Recently, Division of Reclamation and Mining Safety (DRMS) staff drafted a policy regarding stability analyses of neighboring structures. The draft summarizes adequate factors of safety (FOS ) for non-critical and critical structures . The structures around the Nix mine are, for the most part, considered critical structures. Discussions with the author of the memo , Mr. Tim Cazier, indicate the FOS will be adopted by the MLRB. The FOS are for both static and seismic (from an earthquake) stability analyses. For generalized strength assumptions and critical structures, a FOS of 1 .5 is considered sufficient for static conditions and a FOS of 1 .3 is considered suitable for seismic conditions . The stability of structures within 200 feet of the proposed mining limits was evaluated at three sections. The sections evaluated were at the tallest high wall in each mine cell under anticipated loading conditions around the perimeter of the site as discussed below. The computer program XSTABL was used for the analysis. The method for selecting the critical failure surface for each analyzed loading condition is the following . The Modified Bishop' s Method of Analysis is used to find the critical failure surface by randomly searching with 20 termination points and 20 initiation points (400 failure circles) with 7 foot fine segments over the slope surface and at the structure in question to determine the lowest factor of safety. Both static stability under anticipated mining conditions and seismic stability under peak ground acceleration loads were performed . Seismic loading was obtained from the U .S.G .S. Unified Hazard Tool. Review of the Hazard Tool indicated a maximum horizontal acceleration of 0 .091g with a return period of 2 ,475 years for the site. Page 64 of 123 Mr. Joe Lamanna January 14 , 2020 Page 4 The three cross section locations were selected and analyzed as described below. The locations are shown on Figure 1 . ► Cell 1 : This section is on the northwest side of Cell 1 and considers the tallest mine highwall of this cell . The stability analysis for this section assumes a mine highwall sloped at 2 horizontal toil vertical (2H : IV). The nearest structure is a gas line located approximately 30 feet to the west, The stability analysis on this section was run with potential failure circles initiating at the gas line and terminating in the area near the base of the mine highwall . ► Cell 2: This section is on the south side of cell 2 and considers the tallest highwall in this cell . The stability analysis for this section assumed a 30 foot offset from the sl u rryr wall and a mine slope of 2 horizontal to 'I vertical (2H: IV). The stability analysis on this section was run with potential failure circles initiating at the slurry wall and terminating in the area near the base of the mine highwall. ► Cell 3 ; This section is on the north side of cell 3 and is the tallest highwall in the cell . This section will be capped with approximately 2-feet of compacted overburden fill. The stability analysis for this section assumed a 30 foot offset from the slurry wall and a mine slope of 2 horizontal to Al vertical (2H: IV). State Highway 66 is approximately 100 feet to the north . The stability analysis on this section was run with potential failure circles initiating at the slurry wall and terminating in the area near the base of the mine highwall . MATERIAL PROPERTIES The material index and engineering strengths assumed in this slope stability report are discussed below . Overburden The strength properties for the insitu situ silty to clayey sand overburden were based on field testing data and on our engineering judgment; the following parameters have been used to model the overburden.

Fill 108 118 128 70 30 Alluvial Sand and Gravel The sand and gravel is generally a medium to coarse-grained sand that is medium dense to dense and locally gravelly . The alluvial sand and gravel was modeled as follows : Dry Unit Moist Unit Saturated Unit , WeightOct) Weight o Weight (pct) Cohesion C psf Friction Angle 0 119 129 130 0 35 Bedrock Bedrock below the alluvium is predominately sandstone with local claystone and interlaminated to interbedded claystone and sandstone bedrock. Sandstone is typically stronger than claystone. Claystone is generally a weak bedrock. To be conservative, we modeled the bedrock as claystone. For the claystone bedrock, two potential strength conditions were considered . These strength conditions are referred to as; 1 ) peak strength, and 2) residual strength . Peak strength is the maximum shear strength the claystone bedrock exhibits. The shear strength is made up of both cohesion (diagenetic bonding) and internal friction . Under short-term conditions for unsheared eared claystone, peak strength governs behavior. If a sheared surface or sheared zone is present within claystone as a result of faulting , slippage between beds due to folding, past shrink-swell behavior, stress relief, weathering , or from a landslide, the cohesion along Page 65 of 123 Mfr. Joe Lamanna January 14, 2020 Page b the sheared surface is reduced to zero, and the angle of internal friction is decreased, due to alignment of clay minerals parallel to the shear plane. Linder these conditions a claystone exhibits its lowest strength known as residual strength. Residual strength bedrock occurs in discrete zones, parallel with the sheared surface or zone, whereas fully softened strength occurs over a broader area (not used in this modeling). Based on data from other recent projects and engineering judgment, the residual strength claystone was modeled in a one -foot thick layer overlying the peek strength bedrock as follows: Weight(pct)Weight(pct)Weight(pc0FrictionA� Dry Unit Saturated Unit Moist Unit � 0 Cohesion c1 psiAngie 11 _.

The resulting mix will produce a non -Newtonian fluid with some shear strength characteristics based on a reduced friction angle of the overlying overburden. Based on engineering judgment, we modeled the slurry wail as follows: My Unit Weight Oct) Moist Weight Unit (pct) Saturated Weight Unit Oct) Cohesion Cf Psf Friction Angie 0' � NA 112 115 w 0 STABILITY ANSI L YSES RESULTS The stability analyses assumed the mining will be per the mine plan. The plan includes dewatering with a series of perimeter drains to in Cell +1. Dry mining will occur in cells 2 and 3 as the water level in these cells will be controlled by slurry walls. The perimeter mine slopes of both cells will be no steeper than 2H:1V. Setbacks listed in Table 1 (below) indicate the setback from the structure to the mining limits. The setback distance can be increased as needed to address other restrictions such as weaker than anticipated soils, deeper mining, or unanticipated groundwater. The factor of safety shown below is the minimum factor of safety of the three conditions listed above.

Based on the Factors of Safety listed in the table above, the mine will net be a hazard to neighboring structures provided the structure and slurry gall offsets, as well as the perimeter mine slopes, follow the mine plan. LIMITATIONS Our reviewer is based on regional geologic mapping, present mining plans, and in part borehole data by Civil Resources and others. Stability analyses were performed using typical strength parameters for the various strata in the critical sections. Should the mining plans change or subsurface conditions vary from these portrayed in this letter, we should be contacted in order to re-evaluate the potential affects on permanent man-made structures. Stability analyses were run at the structure in question and were not run on failure surfaces closer to the hig hwa Il. Note also that surcharge loads due to temporary material stockpiles and overburden berms were not considered in the analysis. Please call with any questions or comments.
