They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/ portal/nres/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil Custom Soil Resource Report scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil -landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 8 _ 30 30 11 Custom Soil Resource Report MAP LEGEND MAP INFORMATION Area of Interest (Aol) Spoil Area The soil surveys that comprise your AOI were mapped at Area of Interest (A0l) Stony Spot 1:24,000.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it 11 Custom Soil Resource Report was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Weld County, Colorado, Southern Part 1—Altvan loam, 0 to 1 percent slopes Map Unit Setting National map unit symbol: 361j Elevation: 4,500 to 4,900 feet Mean annual precipitation: 14 to 16 inches Mean annual air temperature: 46 to 48 degrees F Frost -free period: 130 to 150 days Farmland classification: Not prime farmland Map Unit Composition Altvan and similar soils: 90 percent Minor components: 10 percent Estimates are based on observations, descriptions, and transects of the mapunit.

The project site is comprised of an approximately 650 acre site within Section 20 of Township 4 North, Range 66 West of the 6th PM, Weld County, Colorado. The center of the project site is located at 40.297143° latitude and -104.801470° longitude. The property is located west of Gilcrest, Colorado between Colorado Highway 60 on the west, Weld County Road 44 on the north, Weld County Road 29 on the east, and Weld County Road 42 on the south (Figure 1.). The project site is accessed from any of the above roads. Weather during the site investigation was warm, dry, and clear with a temperature in the mid -60's (°F). The topography of the site is dominated by the primary alluvial terrace of the South Platte River. The elevation of the center of the project area is 4760 feet and slopes gently to the west toward the river. The soils that dominate the site are formed from alluvium, with the predominant soils being sandy loams (Julesburg and Bresser map units) and loam (Nunn map unit) and are underlain by aggregate with varying groundwater levels. The significant hydrologic feature near the site is the South Platte River. The project site has been developed for irrigated agriculture, oil and gas production, and a solar energy array, with very little native vegetation remaining. The project site has no tree canopy or shrub understory, with the only trees and shrubs located within the yards of homesteads at the edge of the agricultural fields. Agriculture within the project site is irrigated by pivot and flood irrigation methods. Only one vegetation community or type is found within the proposed Red Tierra Equity project site: irrigated agriculture, either flood or pivot -irrigated. Vegetation Community Irrigated Agriculture Agricultural fields within the project area were in various states of production during the on -site evaluation. The majority of the fields had been harvested for the season, and disked or tilled and left fallow, or replanted. The exception was the northwest quarter section which has been planted to specialty lettuce crops and was in the process of being harvested by variety (Figure 2.). Several fields within the project site have been planted to winter wheat, and germination of the crop was noted (Figure 3.) . Additional fields were noted to have been planted to corn during the 2021 season which has been harvested and the fields disked and tilled prior to anticipated planting. Several irrigation tailwater ponds are located within the project area. These ponds did not contain any native vegetation communities. One irrigation canal and a number of secondary irrigation ditches traverse the project site. None contain areas of native vegetation. Exhibit J Page 1 The Natural Resource Conservation Service soil survey reports yields for common crops (1980) as follows for the Julesburg, Bresser, and Nunn map units; alfalfa hay (5.5 tons/acre), sugar beets (23-24 tons/acre), corn (150-180 bushels/acre), corn silage (33-35 tons/acre), dry pinto beans (2400-2700 pounds/acre), onions (525-550 sacks/acre), and potatoes (325-350 hundredweight/acre). Threatened and Endangered Species and Critical Habitat Potential habitat for the Ute ladies' -tresses orchid (Spiranthes diluvialis), the sole threatened or endangered plant species known in the area, is not present within the project site. There are no subirrigated hay fields with native vegetation containing typical plant associates of the orchid. The current proposed project site does not include disturbance to Ute ladies' -tresses orchid potential critical habitat; therefore, no further evaluation was undertaken. Exhibit J Page 2 Figure 1.

If the operation is intended to be an intermitted operation as defined in C.R.S 34-32.5-103(11)(b), the Applicant should include in this exhibit a statement that conforms to the provisions of Section 31-32.5- 103(11)(b), C.R.S; Mining will commence as soon as possible after the approval of this application which is estimated to be in February. The owner of the property is concurrently applying for a DRMS 112 permit and mining under this DRMS 111 permit will end after approval of the 112 permit or once the permittee has reached the grade shown on the mining plan map. The expected end date for the project is December 2023 or earlier if the above conditions are met. (b) the estimated depth to which soil, suitable as a plant growth medium, will be salvaged for use in the reclamation process. This description must be consistent with information provided in Exhibit B. Sufficient soil must be salvaged to meet the vegetation establishment criteria of Rule 3.1.10. If plant growth medium is not reapplied on a graded area immediately after salvage, then the Operator/Applicant must specify how the topsoil will be stockpiled and stabilized with a vegetative cover or other means until used in reclamation. Plant growth medium stockpiles must be located separate from other stockpiles, out of the way of mine traffic and out of stream channels or drainageways. The location of plant growth medium stockpiles must be shown on Exhibit E - Map; From the exploratory borings that were drilled at the site in 2021, the estimated suitable soil for plant growth is approximately 12 inches. The top 12 inches of soil will be stockpiled to the southern side of the affected area as shown on the Mining Plan Map in Exhibit E. In the event that the topsoil is not utilized within 1 year vegetative cover will be planted. (c) specify the thickness of overburden or quantity of waste rock, if any, to be removed to reach the deposit. The location of any overburden stockpiles or waste rock fills must be shown on Exhibit E - Map; Exploratory borings drilled on the site show that overburden is approximately 5 feet deep in the affected area. The permittee is expecting to utilize overburden for the highway project. Any overburden material not suitable for the permitted end use will be stockpiled in the southern end of the affected area adjacent to the topsoil stockpile. (d) specify the thickness of the deposit to be mined; Bedrock in the affected area is approximately 48 feet deep and groundwater levels in the area are approximately 24.4 to 26.0 feet deep. The pit is expected to be mined to a depth of 20 feet or shallower to avoid exposing groundwater. No groundwater will be exposed during mining under this permit. (e) describe the major components of the mining operation such as: roads and access routes, Section 20 — Gravel Mine — MLRB 111 Permit Amendment Exhibit C pit, office, shop/maintenance buildings, plant, processing facilities, and any underground openings such as adits or ventilation facilities. These components must be located on Exhibit E - Map; The access route to the site will be located to the north side of the site and will enter the site off of Weld County Road 44. There will be one pit at the site which will be contained by the access road to the east and an existing dirt farm road to the west. The pit will be approximately 22.45 acres. The location of the access route and pit are shown on Exhibit E. (f) specify the dimensions of any significant disturbances to the land surface such as pit excavations, mine benches, impoundments, stockpiles, waste rock disposal areas, etc; The pit will be approximately 22.45 acres and the stockpile area will be approximately 1.87 acres. (g) 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 permitted acreage. Describe any associated drainage and runoff conveyance structures to include sufficient information to evaluate structure sizing; An existing 30 feet by 1434 feet farm access road will be utilized for the mining operation. No improvements will be made to the existing road. (h) specify how much water will be used in conjunction with the operation, and the source of this water; There will be no onsite processing. The only water used will be for dust suppression at the site. (i) if groundwater will be encountered and/or surface water intercepted or disturbed, describe how mining will affect the quantity and quality of the surface or groundwater and the methods to be used to minimize disturbance to the surface and groundwater systems including proposed dewatering, sediment -containment or chemical treatment systems, storm water run-off controls, and groundwater points of compliance; No groundwater will be encountered, and stormwater run-off will be directed into the pit. No other surface water features will be intercepted or disturbed. (/) specify how you will comply with applicable Colorado water laws and regulations governing injury to existing water rights; No groundwater will be exposed during the operation under this permit and no existing surface water conveyances will be disturbed. (k) if refuse and acid or toxic producing materials are exposed during mining, describe how they shall be handled and disposed of in a manner that will control unsightliness and protect the drainage system from pollution; Section 20 — Gravel Mine — MLRB 111 Permit Amendment Exhibit C No refuse or acid or toxic producing materials are expected to be exposed during mining. If any of these materials are exposed during mining they will be segregated and loaded in the pit to control for unsightliness and to protect the drainage system from pollution. These materials will be disposed of at the appropriate disposal facility. (1) describe what measures will be taken to minimize disturbance to the hydrologic balance, prevent off -site damage, and provide for a stable configuration of the reclaimed area consistent with the proposed future land use; The permittee will not expose groundwater at the site and will direct stormwater from disturbed areas back into the pit. The site is concurrently applying for a DRMS 112 permit along with this DRMS 111 permit. The pit covered in this permit application will ultimately be incorporated into a larger soil-bentonite lined cell that is covered in the DRMS 112 permit. The ultimate final land use for this area is a below grade soil-bentonite lined reservoir. In the event that the DRMS 112 permit application is postponed or denied, the mining pit will be reclaimed as an infiltration pond. (m) specify whether the deposit will be processed on -site. If the deposit will be processed, then describe the nature of the process, facilities and chemicals utilized. The process area and any structures must be described on Exhibit E - Map; There will be no on -site processing. (n) identify the primary and secondary commodities to be mined/extracted and describe the intended use; and The primary commodities to be mined are overburden, sand, and gravel for use as construction aggregates. There will be no secondary commodities mined. (o) name and describe the intended use of all expected incidental products to be mined/extracted by the proposed operation. Topsoil will be stockpiled to the south of the affected area. All other materials that are mined are expected to be utilized by the roadway project. (p) Specify if explosives will be used in conjunction with the mining or reclamation. In consultation with the Office, the Applicant must demonstrate, pursuant to Subsection 6.5(4), Geotechnical Stability Exhibit, that off site areas will not be adversely affected by blasting during mining or reclamation operations. No explosives will be used in conjunction with the mining or reclamation. Section 20 — Gravel Mine — MLRB 111 Permit Amendment Exhibit C EXHIBIT D EXHIBIT D - RECLAMATION PLAN The information provided in this Exhibit is intended to satisfy the requirements outlined in Section 6.3.4 of the Colorado Mined Land Reclamation Board Construction Material Rules and Regulations: (1) The purpose of the Reclamation Plan is to describe the timing, procedures, criteria and materials that will be used to reclaim the affected land to the proposed future land use. This plan must be correlated to Exhibit E - Map. The description of the Reclamation Plan must be adequate to satisfy the requirements of Section 3.1 and demonstrate compliance with Rule 3. At a minimum, the Application shall include the following information: (a) specify at what point in the mining plan and to what depth(s) overburden will be replaced in relation to ongoing extraction. Overburden will be utilized offsite as a primary commodity and will not be replaced in the mine pit. The pit will be located within the future mine limit of a soil-bentonite lined mine cell under a DRMS 112 permit which has been submitted to the DRMS and is currently under review. In the case that the DRMS 112 permit is delayed or not approved, the mine pit will be reclaimed to an infiltration pond and no overburden will be utilized. (b) specify the maximum gradient of reclaimed slopes (horizontal: vertical). If the Application proposes slopes steeper than 3:1, the Operator/Applicant must include a justification that supports steeper slopes for the proposed post -mining land use, and demonstrates compliance with the applicable performance standards of Section 3.1. The maximum gradient of the mined and reclaimed slope will be at a 3:1. (c) specify the measures that will be taken to revegetate the site, if applicable, including: The site is currently utilized as flood irrigated farmland. The final end use for this area is planned to be water storage or as an infiltration pond. In disturbed areas above the highwater line and outside of the pit the land will be revegetated with the Weld County upland seed mix utilizing the stockpiled topsoil. (i) state the thickness of plant growth medium to be replaced. Sample and analyze available soils sufficiently to establish quantity and quality; The affected area is currently flood irrigated cropland that is tilled yearly and left fallow in the winter. The permittee will reseed disturbed areas outside of the pit with the Weld County Upland Seed Mix, attached to this Exhibit. (ii) state at what point in the mining plan the site will be seeded. Explain how the seedbed will be prepared to eliminate compacted conditions (e.g., plowed, chiseled, disced). State the type, application rate, and soil incorporation methods of fertilizer application, if any. NOTE: Soil amendments shall only be applied where soil tests indicate nutrient deficiencies for the plant species to be established; The pit will be located in the future mine limit of what will be Phase 1 of a DRMS 112 permit which is currently under review. In the event that mining under this permit is complete prior to Section 20 — Gravel Mine — MLRB 111 Permit Application Exhibit D- 1 approval of the DRMS 112 permit or the DRMS 112 permit is not approved, reclamation will begin and the disturbed areas above the high water level and outside of the pond will be reseeded. (iii) state the grass, forb, shrub and tree species to be planted and the applicable quantities. Specify the quantity of each grass and forb species as pounds of pure live seed per acre; Areas South of County Road 68 • Mix Western Wheatgrass (Arriba, Barton, Rosana) 2.50 lbs pls/acre • Blue Grama (Hachital, Lovington) 1.50 lbs pis/acre • Sideoats Grama (Vaughn, Butte, Niner, El Reno, Haskell) 2.25 lbs pis/acre • Smooth Brome (Lincoln, Manchar) 2.00 lbs pls/acre • Sand dropseed 0.25 lbs pls/acre • Perennial Ryegrass (Calibra or Garibaldi tetraploid) 0.75 lbs pls/acre • Slender Wheatgrass (Pryor, Revenue or San Luis) 2.50 lbs pls/acre • Alkaligrass (Fults II, Salt on Sea) 1.25 lbs pis/acre • Switchgrass (Nebraska 28, Blackwell) 1.00 lbs pls/acre Total: 14.00 pound pls/acre (iv) specify the application method for grass and forb seeding. If the seed is to be broadcast, the application rate shall be twice the rate required for seed drilling. If the seedbed has not been adequately roughened prior to seeding, the seed shall be raked or harrowed after broadcast application; The seed mixture will be drilled and mulched. (v) if a mulch is needed, specify the kind to be used, the crimping method, and rate of application; and Straw mulch will be at 2 tons/acres and will be incorporated into the soil with a studded roller or crimper. (vi) explain the establishment methods for each species of shrub and/or tree, and state the number of each to be established per acre. Not Applicable (d) Specify which ponds, streams, roads and buildings, if any, will remain after reclamation. These features must be shown on the Exhibit E - Map. If ponds are part of the Reclamation Plan, slopes from 5 vertical feet above to 10 vertical feet below the expected average water level cannot be steeper than 3H:1 V; remaining slope lengths may not be steeper than 2H:1V. Where wildlife habitat is the proposed future land use, shorelines should be irregularly shaped to promote a diverse wildlife habitat. The Colorado Division of Wildlife (DOW) must be consulted where wildlife use is the proposed future land use. The main pit will remain after reclamation and will either be water storage or a infiltration pond. The whole reclamation slope will be reclaimed at a 3:1 slope. Section 20 — Gravel Mine — MLRB 111 Permit Application ExhibitD-2 - 2 (e) Specify the reclamation treatment of any waste rock dumps, underground mine openings, ditches, sediment control facilities, buildings and other features specified in your mine plan but not previously addressed in the Reclamation Plan narrative. These features must be shown on Exhibit E - Map. This should describe the measures taken to minimize disturbance to the hydrologic balance, prevent off -site damage, and provide for a stable configuration consistent with the proposed future land use. All features have been addressed.

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 approximately '/4 of a mile west of the town of Gilcrest. More specifically, the site occupies nearly all of Section 20, Township 4 North, Range 66 West of the 6th Principal Meridian. The mine is in an area of irrigated agricultural land with common oil and gas wells and related infrastructure and is bound by Weld County Road (WCR) 42 on the south, State Highway 60 on the west, WCR 44 on the north, and WCR 29 on the east. The mine will consist of eight (8) cells. One (1) of the cells will be wet mined at a mine slope of 2 horizontal to 1 vertical (2h:1 v) and backfilled with the silt byproduct of the wash plant operation. The other seven (7) cells will be lined with slurry walls and will be dry mined at slopes of 1.5h:1. 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 21 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 beneath the site is most likely the Laramie Formation. Colton (1978) describes the Laramie as mostly claystone, shale, sandy shale, and lenticular sandstone. The Lower Laramie is described as sandstone, sandy shale, and claystone with several coal beds. The regional mapping indicates the bedrock is overlain by the Broadway Alluvium. Colton (1978) describes the Broadway as sand and gravel deposited by the South Platte River and its tributaries that is terraced typically lying about 40 feet above major streams. Along the South Platte River, the Broadway is typically on the order of 35 feet thick but can range up to 125 feet thick. GEOTECHNICAL CONDITIONS Based on the site investigations, the natural site stratigraphy generally consists of four main units: 1) Overburden: generally consisting of near surface fine to medium grained sand locally grading to silty or clayey sand; 2) Sand and Gravel: alluvial deposits that underlie the overburden and overlie the bedrock; 3) Mud Lens: silty to clayey sand Mr. Peter Kubiak December 30, 2021 Page 2 commonly interbedded within the sand and gravel unit; and 4) bedrock usually consisting of sandy claystone and sandstone that is commonly weathered in the top 1 foot and is commonly interbedded and interlaminated. Overburden The overburden is typically a fine to medium grained sand that locally grades to silty or clayey sand typically ranging from 0 to 7 feet in thickness. This unit is usually slightly moist to moist, loose to medium dense with the top 6 to 8 inches containing significant organics. Of the overburden samples tested, the range of percent passing the No. 200 sieve ranged from 4.1 % to 31.9%. Atterberg Limits testing ranged from granular non -plastic to Liquid Limits of 26 and Plasticity Indices of 9. Sand & Gravel The sand and gravel is present throughout the site locally occurring at the surface, but typically underlying the overburden and overlying the bedrock. This unit typically consists of slightly silty, fine to medium grained sand overlying or grading to a a fine to coarse grained sand and/or gravelly sand. This unit is typically medium dense but locally dense. This unit is commonly fifty (50) feet thick but is locally as thick as eighty-five (85) feet. Mud Lens The mud lens unit is locally interlensed within the sand and gravel unit. This unit typically consists of clayey to silty sand. Thickness varies from one (1) foot to as much as fifteen (15) feet. This unit tends to be thicker on the south part of the site. Bedrock The bedrock encountered in the exploratory borings was generally weathered in the upper foot typically became harder in unweathered zones. The bedrock consisted of sandy claystone. Groundwater Groundwater was encountered in all of the borings at approximately 15 to 25 feet below ground surface. The groundwater levels will vary seasonally and will typically rise during the irrigation season and when recharge is applied. Groundwater will be controlled with the proposed below grade slurry wall and by pumping down the water level on the interior of the slurry wall. After slurry wall construction, groundwater mounding is anticipated on the upgradient (south and southeast) side of the site and a groundwater shadow (deeper water table) is anticipated on the downgradient (north and northwest) 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. With the exception of the silt pond, dry mining is planned in the cells as the slurry wall will control water level in the main cell and mining will be above the water table in the other cell. STRUCTURES WITH 200 FEET OF DISTURBED AREAS The known, permanent, man-made structures within 200 feet of the proposed mine areas that are not owned by the miner are listed below: • PDC Energy- Flowline, Flare Stack, Tanks, Oil/Gas Well • DCP Energy- Gas Line • Weld County Public Works- Weld County Road 44 STABILITY ANALYSES 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 Section 20 mine are, for the most part, considered critical structures. The FOS are for both static and seismic Mr. Peter Kubiak December 30, 2021 Page 3 (from an earthquake) stability analyses. For generalized strength assumptions and critical structures, an FOS of 1.5 is considered sufficient for static conditions and an 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 representative sections 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 line segments over a broad range of the slope surface and at the structure in question. This procedure is repeated over different initiation and termination locations until the most critical factor of safety failure surface is identified. The range is narrowed and 20 initiation points and 20 termination points (400 failure circles) with 7 -foot line segments for the final run of 400 circles to determine the lowest factor of safety. Therefore, prior io submitting the final stability run, at least 800 failure surfaces were analyzed 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 attached to this report. Review of the Hazard Tool indicated a maximum horizontal acceleration of 0.082g with a return period of 2,475 years for the site. The three cross section locations were selected and analyzed as described below. ► Section 1: This section is in the northwest corner of the site in an area that will be wet mined prior to being backfilled with silt. This section considers a 50 -foot tall highwall at a point where the mine limit is 40 feet from a gas line. The overburden is modelled at 5 -feet thick and a 2 -foot thick mud lens is modeled within the sand and gravel. This is the most critical section to be wet mined as it marks the point where a tall highwall (deepest bedrock) and closest structure coincide. Section 2: This section is the most typical section at the site. This section considers a 50 -foot tall highwall at a point where the mine limit is 30 feet from the slurry wall. The nearest structure is a gas line located 20 feet beyond the slurry wall (total distance 50 feet from the highwall). The overburden is modelled at 5 -feet thick and a 5 -foot -thick mud lens is modeled within the sand and gravel. The analysis was run with failure circles starting at 40 -feet from the highwall. Because the FOS meets DRMS standards, structures can be as close as 40 -feet from the highwall. The nearest structure is actually 50 -feet from the highwall. Section 3: This section is on the southeast part of the site and is the section with the greatest highwall. This section considers an 85 -foot tall highwall at a point where the mine limit is 73 -feet from the slurry wall. The nearest structure is a gas line located 20 feet beyond the slurry wall (total distance 93 -feet from the highwall). The overburden is modelled at 5 -feet thick and a 15 -foot -thick mud lens is modeled within the sand and gravel. The analysis was run with failure circles starting at the slurry wall. Because the FOS at the slurry wall meets DRMS standards and all structures are further from the highwall than the slurry wall, all structures in this area will be stable. MATERIAL PROPERTIES The material index and engineering strengths assumed in this slope stability report are discussed below. Overburden and Mud Lens The strength properties for the in situ silty to clayey sand overburden and mud lens were based on field testing data and on our engineering judgment; the following parameters have been used to model the overburden.

The alluvial sand and gravel unit was modeled as follows: Dry Unit Weight c Moist Unit Weight(pct) Saturated Unit Weight c I Cohesion C' psfI Friction Angle ' ° 115 119 129 0 35 Bedrock Bedrock below the alluvium is sandy claystone, sandstone 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 claystone, peak strength governs behavior. If a sheared surface or sheared zone is present within sandy claystone because of faulting, slippage between beds due to folding, past shrink -swell behavior, stress relief, weathering, or from a landslide, the cohesion along 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. Under 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 site investigations, the residual strength claystone was modeled in a 3/4 -foot thick, weathered layer overlying the peak strength bedrock as follows: Dry Unit I Moist Unit I Saturated Unit Weight (pcfl I Weight (pct) I Weight (pci) I Cohesion C' psf I Friction Angle 0' ° 116 Peak =126 I Peak =135 I Peak =100 I Peak = 29 Residual = 110 I Residual =133 I Residual = 0 I Residual = 18 Soil-Bentonite Slurry Wall The proposed slurry wall will consist of a mix of the overburden clayey to silty sand, alluvial sand, and imported bentonite. 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 wall as follows: Dry Unit Weight (pct) I Moist Unit Weight (pct) I Saturated Unit Weight (pct) Cohesion C' psf Friction Angle '1" ° NA I 112 115 I 0 I 0 STABILITY ANALYSES RESULTS The stability analyses assumed the mining will be per the mine plan. The plan includes wet mining in the cell to receive silt and dry mining in the other seven (7) cells as the water level in these cells will be controlled by slurry walls. The mine slopes in the wet mined cell will not exceed 2h:1v. Mine slopes in the slurry wall lined cells will not exceed 1.5h: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. The factor of safety shown below is the minimum factor of safety of the three conditions listed above.

LIMITATIONS Our review is based on regional geologic mapping, present mining plans, and in part borehole data by Civil Resources. 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 those 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 highwall. 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.
