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.nrcs.usda.gov/wps/ portal/nrcs/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=nrcs) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nrcs142p2_053951). 142p2_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 5 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 6 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 Custom Soil Resource Report MAP LEGEND Area of Interest (AO!)

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 11 Custom Soil Resource Report 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 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.

A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each interpretation. Land Classifications Land Classifications are specified land use and management groupings that are assigned to soil areas because combinations of soil have similar behavior for specified practices. Most are based on soil properties and other factors that directly influence the specific use of the soil. Example classifications include ecological site classification, farmland classification, irrigated and nonirrigated land capability classification, and hydric rating. Ecological Classification Name: NRCS Rangeland Site (Cogburn Area Soils) Ecological classifications consist of a series of vegetative classification systems developed by various partners in the National Cooperative Soil Survey. The classifications include, but are not limited to, systematic vegetative groupings. Examples include NRCS ecological sites, United States Forest Service plant associations, and forage suitability groups. The classifications systems are identified by the Ecological Classification Type Name field, which is in the Component Ecological Classification table. 25 Custom Soil Resource Report Map Ecological Classification Name: NRCS Rangeland Site (Cogburn Area Soils) Feet 0 450 900 1800 2700 Map projection: Web Mercator Corner coordinates: WGS84 Edge tics: UTM Zone 13N WGS84 26 Custom Soil Resource Report MAP LEGEND Area of Interest (AO!)

The Ecological Site Assessment section includes ecological site descriptions, plant growth curves, state and transition models, and selected National Plants database information. All Ecological Sites — (Cogburn Area Soils) An "ecological site" is the product of all the environmental factors responsible for its development. It has characteristic soils that have developed over time; a characteristic hydrology, particularly infiltration and runoff, that has developed over time; and a characteristic plant community (kind and amount of vegetation). The vegetation, soils, and hydrology are all interrelated. Each is influenced by the others and influences the development of the others. For example, the hydrology of the site is influenced by development of the soil and plant community. The plant community on an ecological site is typified by an association of species that differs from that of other ecological sites in the kind and/or proportion of species or in total production. An ecological site name provides a general description of a particular ecological site. For example, "Loamy Upland" is the name of a rangeland ecological site. An "ecological site ID" is the symbol assigned to a particular ecological site. The map identifies the dominant ecological site for each map unit, aggregated by dominant condition. Other ecological sites may occur within each map unit. Each map unit typically consists of one or more components (soils and/or miscellaneous areas). Each soil component is associated with an ecological site. Miscellaneous areas, such as rock outcrop, sand dunes, and badlands, have little or no soil material and support little or no vegetation and therefore are not linked to an ecological site. The table below the map lists all of the ecological sites for each map unit component in your area of interest. 34 Feet 0 450 900 1800 2700 Map projection: Web Mercator Corner coordinates: WGS84 Edge tics: UTM Zone 13N WGS84 35 p Custom Soil Resource Report MAP LEGEND Area of Interest (AO!)

An Approved Jurisdictional Determination (AJD) is a Corps document stating the presence or absence of waters of the United States on a parcel or a written statement and map identifying the limits of waters of the United States on a parcel. AJDs are clearly designated appealable actions and will include a basis of JD with the document.2 AJDs are case -specific and are typically made in response to a request. AJDs are valid for a period of five years unless new information warrants revision of the determination before the expiration date or a District Engineer has identified, after public notice and comment, that specific geographic areas with rapidly changing environmental conditions merit re -verification on a more frequent basis.3 On January 18, 2023, the Environmental Protection Agency (EPA) and the Department of the Army ("the agencies") published the "Revised Definition of `Waters of the United States," 88 FR 3004 (January 18, 2023) ("2023 Rule"). On September 8, 2023, the agencies published the "Revised Definition of `Waters of the United States'; Conforming", which amended the 2023 Rule to conform to the 2023 Supreme Court decision in Sackett v. EPA, 598 U.S., 143 S. Ct. 1322 (2023) ("Sackett"). This Memorandum for Record (MFR) constitutes the basis of jurisdiction for a Corps AJD as defined in 33 CFR §331.2. For the purposes of this AJD, we have relied on Section 10 of the Rivers and Harbors Act of 1899 (RHA),4 the 2023 Rule as amended, as well as other applicable guidance, relevant case law, and longstanding practice in evaluating jurisdiction. 1. SUMMARY OF CONCLUSIONS. I While the Revised Definition of "Waters of the United States"; Conforming had no effect on some categories of waters covered under the CWA, and no effect on any waters covered under RHA, all categories are included in this Memorandum for Record for efficiency. 233 CFR 331.2. 3 Regulatory Guidance Letter 05-02. 4 USACE has authority under both Section 9 and Section 10 of the Rivers and Harbors Act of 1899 but for convenience, in this MFR, jurisdiction under RHA will be referred to as Section 10.

SECTION 10 JURISDICTIONAL WATERS6: Describe aquatic resources or other features within the review area determined to be jurisdictional in accordance with Section 10 of the Rivers and Harbors Act of 1899. Include the size of each aquatic 5 This MFR should not be used to complete a new stand-alone TNW determination. A stand-alone TNW determination for a water that is not subject to Section 9 or 10 of the Rivers and Harbors Act of 1899 (RHA) is completed independently of a request for an AJD. A stand-alone TNW determination is conducted for a specific segment of river or stream or other type of waterbody, such as a lake, where upstream or downstream limits or lake borders are established. 6 33 CFR 329.9(a) A waterbody which was navigable in its natural or improved state, or which was susceptible of reasonable improvement (as discussed in § 329.8(b) of this part) retains its character as "navigable in law" even though it is not presently used for commerce, or is presently incapable of such use because of changed conditions or the presence of obstructions. 2 CENWO SUBJECT: 2023 Rule, as amended, Approved Jurisdictional Determination in Light of Sackett v.

SECTION 404 JURISDICTIONAL WATERS: Describe the aquatic resources within the review area that were found to meet the definition of waters of the United States in accordance with the 2023 Rule as amended, consistent with the Supreme Court's decision in Sackett. List each aquatic resource separately, by name, consistent with the naming convention used in section 1, above. Include a rationale for each aquatic resource, supporting that the aquatic resource meets the relevant category of "waters of the United States" in the 2023 Rule as amended. The rationale should also include a written description of, or reference to a map in the administrative record that shows, the lateral limits of jurisdiction for each aquatic resource, including how that limit was determined, and incorporate relevant references used. Include the size of each aquatic resource in acres or linear feet and attach and reference related figures as needed. a. Traditional Navigable Waters (TNWs) (a)(1)(i): N/A b.

Include the type of excluded aquatic resource or feature, the size of the aquatic resource or feature 7 This MFR is not to be used to make a report of findings to support a determination that the water is a navigable water of the United States. The district must follow the procedures outlined in 33 CFR part 329.14 to make a determination that water is a navigable water of the United States subject to Section 10 of the RHA. 3 CENWO SUBJECT: 2023 Rule, as amended, Approved Jurisdictional Determination in Light of Sackett v.

Based on the site visit, these ditches lack physical indicators of relatively permanent flow. In addition, the USGS topographic map and historic arial do not show that these ditches were constructed in aquatic resources. Therefore, AgDitch 1-27 are excluded under (b)(3), ditches (including roadside ditches) excavated wholly in and draining only dry land and that do not carry a relatively permanent flow of water. These ditches are not waters of the United States. b. Describe aquatic resources and features within the review area that were determined to be non jurisdictional because they do not meet one or more categories of waters of the United States under the 2023 Rule as amended (e.g., tributaries that are non -relatively permanent waters; non -tidal wetlands that do not have a continuous surface connection to a jurisdictional water).

Fort Collins, CO 80524 ,,L*wEs 48IDJ Four Star Court, Fort Collins, CO 8524 Introduction The following report presents the results of a slope stability analysis for a proposed open cut gravel extraction operations at the Raptor Materials, LLC (Raptor) Pit 125 operations located near Platteville, Colorado. This analysis was performed at the request of Raptor. This report is being submitted in partial fulfillment of an OMLR 112 Mine Permit Application. Background Information The proposed gravel quarry is located in portions of section 29, Township 3 North, Range 67 West of the 6th principal meridian. The surrounding land use consists of agricultural, rural residential and natural gas and oil gathering operations. The proposed mine occupies an estimated 197 acres. The water table at the site is located in unconsolidated alluvial deposits with the depth to water varying between seven and 28 feet below ground surface. Soil conditions generally consist of varying thicknesses of top soil underlain by sand and gravel deposits, which in turn are underlain by claystone and sandstone bedrock. Over the entire area the average saturated thickness of the sand and gravel deposits (prior to mining) is estimated at about 35 feet. It is our understanding that the sand and gravel will be dewatered during aggregate extraction. The site location is presented on Figure 1. Previous Investigations Raptor conducted a sand and gravel study in August 2023. The study consisted of drilling six soil borings from ground surface to bedrock to determine the potential aggregate mass within the proposed mine boundary. Selected sand and gravel samples were obtained for direct shear testing. The depth to bedrock over the site varied between 23 and 50 feet below ground surface. The geotechnical laboratory report is presented as Attachment A. Soil boring logs are presented in Attachment B. Overview of Stability Analyses Soil strength testing for the sand and gravel deposits was performed as part of the Raptor study. Density testing was not performed on field samples and unit weights used by the Division of Reclamation and Mining Safety were used for bedrock and overburden clay. Unit weight values reported by Engineering Analytics, Inc., of Fort Collins, CO for were used for the sand and gravel deposits.

The software package PC-STABL was used to evaluate slope stability. Simulations using Spencer, and Modified Bishop methods were ran to determine the most conservative safety factor. The soil strength properties used in the analysis are presented on computer generated data sheets which are presented in Attachment B. Stability analyses were ran for the following scenarios: a 23 foot mine depth with a bank cut of 1.25H:1V, and a 50 foot mine depth with a bank cut of 3H:1V for the bottom 20 feet and 1.25H:1V for the remaining slope. It was assumed that a safety factor of 1.3 or greater will meet regulatory approval. Discussion As the stratigraphy, other than depth to bedrock, did not vary greatly across the study area two model runs were made to simulate the conditions encountered during drilling. A review of the model results indicate that a safety factor of slightly greater than 1.3 is Slope Stability Analysis Raptor Pit 125 Weld County, Colorado Page 3 achieved for a uniform slope of 1.25H:1V at a bank height of 23 feet — this safety factor is contingent on the lower sand and gravel deposits having a friction angle of 38 degrees. This scenario is depicted on Plate 1 in Attachment C. Model results indicate that using a lower bank slope (20 feet) of 3H:1V will result in safety factors of greater than 1.3 at a bank height of 50 feet. This scenario is depicted on Plate 2. Using the different wet unit weights reported in Table 1, resulted in safety factor differences of less than 2 percent. If any significant modifications to proposed pit wall slopes occur this analysis may not be representative of site conditions and additional simulations are recommended.

All samples were obtained by AWES, LLC. The samples tested and tests conducted were assigned by personnel from AWES, LLC. All of the testing was performed by Engineering Analytics under the direct supervision of a licensed Professional Engineer in the State of Colorado. All of the tests were performed in general accordance with the American Society of Testing and Materials (ASTM) procedures unless noted otherwise. Where ASTM procedures were not applicable, the testing was performed in general accordance with acceptable industry standards and the deviations were noted in the report. No major problems were encountered with the laboratory testing. Presented in this report are all of the test results and relevant graphs. 2.0 Direct Shear The Direct shear tests were performed in general accordance with ASTM D3080. The test is performed by deforming a specimen at a controlled strain rate on or near a single shear plane determined by the configuration of the apparatus. Generally, three or more specimens are tested, each under a different normal load, to determine the effects upon shear resistance and displacement, and strength properties such as Mohr strength envelopes. t4 - a) co w Shear Stress, psf 9000 6000 3000 9000 7500 6000 4500 3000 1500 0 0 3000 6000 /+ 1 / 1 ft I r 5 10 15 Strain, % 20 3 2 1 9000 12000 Normal Stress, psf 15000 18000 S ample No. 1 2 3 ca C Water Content, % Dry Density, pcf Saturation, % Void Ratio Diameter, in.

Prior to initiation of these uses of groundwater, the Applicant will need to obtain either a gravel pit or other type of well permit, as applicable. 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 https://dwr.colorado.gov Jared S. Polis, Governor I Dan Gibbs, Executive Director I Jason T. Ullmann, State Engineer/Director Cogburn Pit, DRMS File No. M-2025-016 Page 2 of 3 April 16, 2025 ei Prior to obtaining a welt permit, an approved substitute water supply plan or decreed plan for augmentation is required. Prior to approving a welt permit, the Applicant must conduct a field inspection of the site and document the locations of all wells within 600 feet of the permit area. The Applicant must then obtain a waiver of objection from all well owners with wells within 600 feet of the permit area or request a hearing before the State Engineer. COMMENTS: The subject application is for a surface mining and processing operation on approximately 196.4 acres, generally located in Sec. 29, Twp. 3 North, Rng. 67 West, 6th P.M., Weld County. The mining operation consists of mining and processing sand and gravel to produce construction materials. The area will be revegetated and reclaimed as lined groundwater storage reservoirs (approximately 22.1 acres identified as P125A and 28.2 acres identified as P125B) and a portion of the exposed area (approximately 10.4 acres identified P125_S1) will be backfilled with overburden from the adjacent sites Kurtz Pit (M1999-006) and Bearson Pit (M2015-003). The mining plan is estimated for 8 to 9 years following an additional five years to complete reclamation. The primary materials to be mined at the site are sand and gravel. Mining will occur in the alluvium of the St. Vrain River. Estimated depth to groundwater is 14 to 16 feet in the norther corner of P125A and between 7 to 9 feet in the eastern boundary of P125B. Groundwater will be consumed by evaporation, dust control, dewatering, water removed in the mined product, washing, and reclamation. Prior to the use or exposure of any groundwater, the Applicant must first obtain a well permit and a substitute water supply plan ("SWSP") or decreed plan for augmentation to replace depletions caused by groundwater consumption. The site must continue to be operated under a SWSP or plan for augmentation until such time as the proposed reservoirs are lined (lining approved by this office, backfilling is completed, and replacement of lagged depletions shall continue until there is no longer an effect on stream). The application Cogburn Pit, DRMS File No. M-2025-016 Page 3 of 3 April 16, 2025 indicates that the Applicant wilt apply for a gravel pit well permit, subject to the 600 -foot spacing requirement, and an SWSP to augment river depletions. Additionally, according to our records, there are several wells located on the subject property. Such wells must be operated in accordance with their permitted conditions and applicable statutes. Such wells cannot be used for the mining operation unless they are permitted for such use. If any wells will be plugged and abandoned, they must be plugged and abandoned in accordance with the Well Construction Rules 2 CCR 402-2 and a Welt Abandonment Report must be filed with this office. Additionally, in certain areas of the South Platte River Basin, SEO staff have observed groundwater problems that appear to be related to the lining of gravel pits located near streams, and in particular, these problems occur when multiple liners are located adjacent to each other. DRMS should consider the siting and design of lined gravel pits to ensure that they will not individually or cumulatively result in impacts to the timing and quantity of groundwater flow from upgradient locations back to the stream system. In addition to impacts to property, such as flooding upgradient and reduced water levels downgradient of the liner, there are decrees of the court that specify the timing, quantity, and amount of water depleted from the streams by wells and accreted to the stream through recharge operations. The installation of a gravel pit liner should not result in changes to the timing, location, and amount of such groundwater flows. In anticipation of this concern, the application indicates that mitigation measures such as dewatering wells or a perimeter drain will mitigate any mounding. Any stormwater runoff intercepted by this operation that is not diverted or captured in priority must infiltrate into the ground or be released to the stream system within 72 hours. Otherwise, the operator will be required to make replacements for evaporation. The Applicant may contact the State Engineer's Office at (303) 866-3581 with any questions.

Last Chance acknowledges receipt of notice dated April 1, 2025, from Raptor Materials LLC ("Raptor"), regarding the above referenced matter. Last Chance appreciates the opportunity to provide the following information in response to Raptor's notice and to provide the Division of Reclamation, Mining, and Safety ("DRMS") context and clarification on Last Chance's interest in this matter. Last Chance is a Colorado mutual ditch company which was formed in 1872. Last Chance's primary purpose is to deliver to its shareholders water rights decreed to the Last Chance Ditch. While the diversion point and conveyance infrastructure for Last Chance's decreed water rights are located outside the proposed permit boundaries under DRMS # M-2025-016 as proposed in Raptor's notice, Last Chance's water rights are conveyed through the Last Chance Ditch, which diverts such water rights from St. Vrain Creek through the headgate, and then conveys them through the Last Chance Ditch (as shown on Exhibit B to Raptor's notice, just to the east of the permit area. While Last Chance does not oppose Raptor's proposed current permit sought herein, Last Chance requests that DRMS condition any such permit amendment approval on terms and conditions to be negotiated by and between Raptor and Last Chance that would fully protect Last Chance's real property interests prior to commencement of the permitted mining operations in the area adjacent to the Ditch. Additionally, Last Chance is aware that post -mining, Raptor intends to develop lined water storage reservoirs on one or more of the subject parcels. Again, Last Chance does not oppose such post - mining land use but requests that DRMS condition any such permit amendment approval on terms and conditions to be negotiated by and between Raptor and Last Chance that would fully protect Last Chance's real property interests from any approved post -mining operations in the area adjacent to the Ditch. Last Chance does not submit any additional response at this time, but reserves its right to supplement its response as this application progresses through the DRMS permitting process Please let us know if further documentation or a meeting would be beneficial to address this in greater detail.

July 1, 2025 ,American Water Enaineering Services, liC Raptor Materials, LLC 8120 Gage Street Frederick, Colorado 80516 Attn: Garrett Varra RE: Comments on Slope Stability Analysis 112C Permit Application Adequacy Review DRMS Letter Date June 24, 2025 Dear Mr. Varra: This letter provides responses to a review of the Slope Stability report generated by American Water Engineering Services, LLC (AWES) for the Raptor Materials, LLC (Raptor) mine located near Platteville, Colorado (identified by Raptor as P125). This letter is intended to address the issues raised in the Division of Reclamation, Mining and Safety (DRMS) letter dated June 24, 2025. The mine permit boundary is depicted on Figure 1. The following summarize DRMS comments by item. 1. Per Rule 6.5(3), please provide an additional slope stability analysis which demonstrates an adequate Factor of Safety under seismic conditions for both presented cases. Per the policies of the Mined Land Reclamation Board, a factor of safety of 1.15 under seismic conditions is the requirement for this case. The 25 foot simulation was ran with a seismic acceleration factor of 0.075, which is the value the Universal Building Code has specified for the Front Range area. The predicted factor of safety for fifty foot simulation was 1.11. The slope was modified by increasing the horizontal distance of the 3:1 slope by 22 feet. Plate A depicts the model generated failure analysis with seismic. 2. Per Rule 6.3.5(2)(e), please provide the location of any significant man-made structures within 200 feet of the permit boundary. This information should be used to assess if critical structures are near the permit and determine what Factor of Safety is adequate for the geotechnical analysis. Critical structures are located within the permit boundary and consist of oil and gas pipelines and irrigation ditches. Residential structures are located to the east of Pit 125A, however, will not be located within 200 feet of any excavation. The location of residential structures is depicted on Figure 2.

To minimize this interference, the salts are converted to oxides by heating the sample under a flame until a dull red color is obtained. The conversion to oxides stabilizes the sample weight and ensures that proper alpha/beta efficiencies are assigned for each sample. Volatile radioisotopes of carbon, hydrogen, technetium, polonium and cesium may be lost during sample heating.

Preparation Information Aliquot Reduced 1205986584 (Ingleside Water DUP) Aliquot volume was reduced due to the sample matrix. Quality Control (QC) Information Duplication Criteria between QC Sample and Duplicate Sample The Sample and the Duplicate, (See Below), did not meet the relative percent difference requirement; however, they do meet the relative error ratio requirement with the value listed below. Sample Analyte Value 1205986584 (Ingleside Water DUP) Beta RPD 39.2* (0.00%-20.00%) RER 2.26 (0-3) RDL Met Sample (See Below) did not meet the detection limit due to the small sample aliquot used. The aliquot was reduced due to the matrix of the sample. The sample was counted the maximum count time in order to achieve the lowest possible MDAs. Sample Analyte Value 1205986584 (Ingleside Water DUP) Alpha Result 1.91 > RDL 5 pCi/L < MDA 6.11 Page 12 of 13 SDG: 705717 Technical Information Gross Alpha/Beta Preparation Information High hygroscopic salt content in evaporated samples can cause the sample mass to fluctuate due to moisture absorption. To minimize this interference, the salts are converted to oxides by heating the sample under a flame until a dull red color is obtained. The conversion to oxides stabilizes the sample weight and ensures that proper alpha/beta efficiencies are assigned for each sample.

Data Summary: All sample data provided in this report met the acceptance criteria specified in the analytical methods and procedures for initial calibration, continuing calibration, instrument controls and process controls where applicable, with the following exceptions. Preparation Information Aliquot Reduced 1205986584 (Ingleside Water DUP) Aliquot volume was reduced due to the sample matrix. Quality Control (QC) Information Duplication Criteria between QC Sample and Duplicate Sample The Sample and the Duplicate, (See Below), did not meet the relative percent difference requirement; however, they do meet the relative error ratio requirement with the value listed below. Sample Analyte Value 1205986584 (Ingleside Water DUP) Beta RPD 39.2* (0.00%-20.00%) RER 2.26 (0-3) RDL Met Sample (See Below) did not meet the detection limit due to the small sample aliquot used. The aliquot was reduced due to the matrix of the sample. The sample was counted the maximum count time in order to achieve the lowest possible MDAs. Sample Analyte Value 1205986584 (Ingleside Water DUP) Alpha Result 1.91 > RDL 5 pCi/L < MDA 6.11 Page 12 of 13 SDG: 705717 Technical Information Gross Alpha/Beta Preparation Information High hygroscopic salt content in evaporated samples can cause the sample mass to fluctuate due to moisture absorption. To minimize this interference, the salts are converted to oxides by heating the sample under a flame until a dull red color is obtained. The conversion to oxides stabilizes the sample weight and ensures that proper alpha/beta efficiencies are assigned for each sample. Volatile radioisotopes of carbon, hydrogen, technetium, polonium and cesium may be lost during sample heating. Miscellaneous Information Additional Comments The matrix spike and matrix spike duplicate, 1205986585 (Ingleside Water MS) and 1205986586 (Ingleside Water MSD), aliquots were reduced to conserve sample volume. Certification Statement Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless otherwise noted in the analytical case narrative.

M-2025-016, and below are follow-up questions that should be addressed. Exhibit C 1. The Pre -Mining, Mining, and Reclamation Plan maps need to be updated to accurately show the monitoring well locations associated with the proposed application. 2. Please provide a Table of the locations of each monitoring well (MW -1 through MW -4) in decimal degrees along with ground surface and top of casing elevations. Exhibit D 3. On page 6 the Applicant states that extraction will not occur in the P -125C area and portions of the P - 125B area until approval of a Technical Revision. The Division will require approval of an amendment to the permit prior to mining P -125C because no mining or reclamation details are included in the application for this area. Because a more robust mining and reclamation plan is needed to address P - 125B being within floodplain the Division shall be consulted prior to submission of a revision to determine the appropriate level of revision. Response required. Exhibit E 4. The Reclamation Plan needs to be updated to be consistent with the initial area of extraction, to exclude areas that are not approved to be mined with approval of this application. 5. Reclamation Plan needs to be updated to address plugging and abandoning the monitoring wells, please note the Reclamation Cost Estimate will need to be updated accordingly. 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 https://drms.colorado.gov/ Jared Polis, Governor I Dan Gibbs, Executive Director I Michael A. Cunningham, Director Joel Renfro Cogburn Sand and Gravel (M2025-016) Page 2of5 Exhibit G 6. Please commit to providing a copy of the approved SWSP allowing for the exposure of groundwater once it is approved. 7. There is a Seep Drainage Ditch located on the east side of P -125A. Please provide additional information on this structure, where the seep is located, what the seep's source is, how does it impact the model for the site and how will it be maintained or mitigated? 8. Please provide a discussion regarding the ephemeral drainage and how Regulation 87 — Dredge and Fill Control Regulation may impact the proposed work around the drainage. 9. Please comment on item #3 of Acord's Objection (May 16, 2025) which states "Upon information and belief, Acord alleges that any excavation of the proposed mine will drain subsoil moisture from Acord' s property which will kill Acord's trees, permanent improvements of material value, and without being able to discern the actual location of Raptor's proposed mining operation, Acord cannot provide further information to the Mined Land Reclamation Board as to what trees of Acord will be killed by such draining of subsoil moisture from Acord' s property." Groundwater Monitoring Plan Review 10. In the Introduction, Figure 1 needs to be updated to include the proposed permit boundary. 11. Section 1.2, Figure 2 needs to be updated to label the individual wells (MW -1, MW -2, etc.), including the major permit structures, e.g. clay -lined walls, and settling ponds. 12. The permit acreage needs to be updated to be consistent with the acreage on the application. 13. Section 2.1, were the monitoring wells constructed using artificial filter pack or was the surrounding formation allowed to collapse around the screen? Additionally, were the monitoring wells developed after installation? 14. Section 2.2, groundwater level measurements will be collected monthly throughout the life of mine and those results will be included as part of the quarterly report to be submitted to the Division. 15. In Section 2.2 it is stated that groundwater levels have been collected monthly since August 2024. Please provide a table with the following information for each monitoring well; top of casing elevation, ground surface elevation, depth to groundwater from top of casing, and distance from ground surface to groundwater surface. 16. Please provide a time series line graph that depicts depth to groundwater from the ground surface for all wells since August 2024. 17. Please provide quarterly potentiometric maps that show the direction of groundwater across the site. Joel Renfro Cogburn Sand and Gravel (M2025-016) Page 3of5 18. The proposed groundwater monitoring plan is not consistent with the Division's Groundwater Monitoring: Sampling and Analysis Plan Guidance Construction Materials and Hard Rock Sites (July 2024). A copy has been attached for your reference. The proposed plan needs to be updated to include the analyte list found in Appendix A of the guidance document. 19. Pursuant to Rule 3.1.7(7)(b)(iv) please provide a description of the quality control and quality assurance methods (e.g. duplicate samples, rinsate samples) to be used during quarterly sampling. 20. Please commit to providing the quarterly baseline groundwater monitoring results along with the monthly level measurements by the following deadlines: • First quarter report due by May 1st of every year. • Second quarter report is due by August 1st of every year. • Third quarter report due by November 1st of every year. • Fourth quarter report is due February 1st of the following year. At the end of five quarters of baseline monitoring the Applicant will have to submit a Technical Revision providing a detailed description of the groundwater quantity and quality conditions at the site and formally designate a point of compliance for the permit, in accordance with Rule 3.1.7(6). The Applicant may include within that Technical Revision, or another Technical Revision, a request to reduce the analyte list and frequency of monitoring with sufficient justification. 21. Appendix B needs to be updated to include the frequency and collection of field parameters during well purging, parameter stabilization, along with the completion of field forms to document that the wells were sampled according to the approved plan. Completed field forms are to be submitted as part of the quarterly monitoring reports. Groundwater Model Review 22. Introduction, the proposed permit boundary is missing from Figure 1, please update. 23. The permit acreage needs to be updated to be consistent with the acreage on the application. 24. The average saturated thickness of the aquifer within the mine boundary is stated to be 35 feet, but a review of the boring and well construction logs from the Groundwater Monitoring Plan indicates that the average saturated thickness at the site is 23 feet. Please clarify this discrepancy and update as needed for consistency. 25. Please provide an explanation of why the developed water resource lakes are being modelled to leak. Routinely, the Division observes the lined lakes as being modelled as no -flow boundary conditions. Joel Renfro Cogburn Sand and Gravel (M2025-016) Page 4 of 5 26. The hydraulic conductivity of St. Vrain Creek has been assigned a hydraulic conductivity of 4 feet/day. Please provide more information on how this value was derived, it appears it may be too conservative of a value. 27. Please provide a discussion on how the ephemeral drainage is being modelled and a summary of its impact on the model. 28. The seep drainage channel does not appear to have been included in the model. Please provide an explanation for leaving it out, if it was inadvertently omitted, please include it. 29. Please submit a new groundwater study and model that demonstrates disturbances to the prevailing hydrologic balance of the affected land and of the surrounding area will be minimized both during and after mining operations and during reclamation activities. The study needs to include proposed developed water resources and structures, approved and proposed, located immediately adjacent to the proposed permit boundary. Permits include Kurtz Resources (M1999- 006), Nix Sand and Gravel (M2001-046), P122 (M2015-033), Heintzelman (M2009-018) and Firestone Gravel (M1996-052). Include in the submittal a demonstration of the effectiveness of any proposed mitigation measures. Please note in certain areas of the South Platte River Basin, staff of the Division of Water Resources, have observed groundwater problems that appear to be related to the lining of gravel pits located near streams, and in particular, these problems occur when multiple liners are located adjacent to each other. The Division of Water Resources requests operators consider the siting and design of lined gravel pits to ensure that they will not individually, or cumulatively, result in impacts to the timing and quantity of groundwater flow from upgradient locations back to the stream system (mounding and shadowing analysis). In addition to impacts to property, such as flooding upgradient and reduced water levels downgradient of the liner, there are decrees of the court that specify the timing, quantity and amount of water depleted from the streams by wells and accreted to the stream through recharge operations. The installation of a gravel pit liner should not result in changes to the timing, location, and amount of groundwater flow. If you need additional information or have any questions, please let me know.

It is intended to supplement the Groundwater Monitoring and Protection Technical Bulletin of November 19, 2019, and is an attempt to provide more detailed and specific guidance to permittees in an area where the Division has found approaches to compliance have varied widely. Sites where mining will not expose groundwater, e.g., dry sites or sites where mining will not be near the water table, are not required to submit a groundwater sampling and analysis plan. A Sampling and Analysis Plan should be tailored to the specific site to which it applies, but this guidance document does not take site -specific factors into account. The remaining sections of this document are organized under the same headings that the Division would expect to see in a typical groundwater sampling and analysis plan. As described in the Technical Bulletin, the Division of Reclamation, Mining and Safety (DRMS/Division) has statutory mandates to monitor groundwater and protect the hydrologic balance during and after mining operations under the Colorado Mined Land Reclamation Act (C.R.S. Title 34, Article 32), and the Colorado Land Reclamation Act for the Extraction of Construction Materials (C.R.S. Title 34, Article 32.5). The Division is requiring groundwater monitoring throughout the life of mine to demonstrate compliance with these statutes for mines that have, or potentially will affect the hydrological balance. Hyperlinks are included in the document text for convenience, and a full list of references is given at the end. Sampling and Analysis Plan Guidance Page 4 of 12 September 2024 1 Background Information 1.1. Site Description The Site Description should include the following: • Name of the site or sampling area. Also include the name or abbreviation (e.g., "the Site"), if any, that will be used throughout the plan. • A general description of the region in which the site or sampling area is located. Include the street address, city, state, and postal code, if appropriate. • A detailed description of the physical geography of the site or sampling area. Include a description of the topography, land use/surface cover, any relevant physical features, past and present activities, existing structures. Give the area in acres. • A description of the geology of the area, including lithology and stratigraphy. Give the composition, thickness and extent of each formation. Identify any faults or other major structural features in the area. Diagrams are often a helpful addition to a geologic description. • A description of the hydrogeology of the area. Identify each aquifer underlying the site. Characterize each aquifer (hydraulic conductivity, isotropy, confined/unconfined, recharge zones, groundwater flow direction) and describe how the characterization was made. Identify aquitards/confining layers. • At least two maps: o A vicinity map that shows the permit area within its geographic region. o A Monitoring Well Location map that shows the sampling sites or sampling areas within the local area. Scale criteria need not be followed for this map. The map should include a layer of projected potentiometric contour lines for each identified aquifer, or a groundwater directional flow arrow (if appropriate). All permitted wells within the map extent should be shown — this information is available from the Division of Water Resources (DWR). All sampling locations (historic, active and planned) should be shown. All springs and seeps should be shown. The outcrop of any geologic formations should be shown. Other physical features and man-made structures may be included for clarity. All maps should include a title, legend, North arrow, scale bar, date, and section lines/marks. All maps must be prepared and signed by a registered land surveyor, professional, engineer, or other qualified person. 1.2. Baseline Groundwater Characterization A Sampling and Analysis Plan will be informed by a baseline characterization of groundwater at the site, but may also need to include a plan to collect the data that will allow the initial characterization to be made. Applicants are encouraged to utilize information available from the public domain literature Sampling and Analysis Plan Guidance Page 5 of 12 September 2024 and private sector data in developing their baseline groundwater characterization. These data sources will not require a Notice of Intent (Rule 5) to perform exploration operations. Private sector sources will likely include environmental site assessments performed as part of land acquisition. Baseline sampling must be sufficient to allow the Division to assess the impacts of the future mining operation on the prevailing hydrologic balance. Sampling locations shall be established upgradient and downgradient of the proposed operation, the number of sampling locations is not specified since it depends greatly on the site, (a minimum of three data points are needed to establish groundwater flow direction). Unless otherwise approved by the Division, all groundwater monitoring wells should be within the permit area. The screened intervals of groundwater monitoring wells should be sufficient to monitor each identified aquifer that maybe impacted by the mining operation. Samples should be taken with sufficient frequency to capture site -specific temporal variability. The duration of the sampling period should be sufficient to identify seasonal trends. The minimum sample location, frequency and duration requirements for baseline groundwater characterization are summarized below: • Upgradient and downgradient sampling locations in each identified aquifer. • Samples taken quarterly for analytical analysis. • Water level data for all wells should be collected at least monthly. • Five consecutive quarters of data, plus additional quarters up to two years may be required and utilized if site activity is delayed. A table should be included with a row for each sampling location. Each point should have a unique identifier. The table should include the location (Lat/Long), land surface elevation, top of casing elevation, total depth, screened interval, and completion date. The latitude/longitude could be shown in decimal degrees showing five places to the right of decimal, e.g., 39.73934, -104.98486. It should be noted that once site groundwater characterization commences, it will be required that groundwater monitoring will continue for the life of the mine. Any modifications to the approved water monitoring plan must be made through the technical revision process with appropriate justification provided by the operator. Analytical sampling frequency will not be reduced to less than a minimum of twice yearly (high flow and low flow data with a collection interval of 5-7 months). Analytical and water level monitoring will not be suspended due to delay in site activity, or placing the site into temporary cessation unless approved by the Division. Upon request, the Division is available for consultation during development of a Sampling and Analysis Plan. 1.2.1. Monitoring Well Installation All monitoring wells should be: • Permitted with the State Engineer's Office (SEO) Division of Water Resources (DWR); and Sampling and Analysis Plan Guidance Page 6 of 12 September 2024 • Constructed (and later abandoned) according to the required SEO standards (see 2 CCR 402-2 Rules and Regulations for Water Well Construction, Pump Installation, Cistern Installation, and Monitoring and Observation Hole/Well Construction) The well construction standards are designed to protect aquifer integrity and to ensure that constructed wells serve their purpose; in this case to provide representative, defensible data. Failure to follow the applicable permitting and well construction rules could result in unacceptable data; and failure to adequately protect groundwater resources could result in subsequent e nforcement action as deemed appropriate by DRMS or the SEO. All wells should be installed by a licensed contractor, as required by SEO. Site specific well placement and construction details should be recorded and approved by a qualified professional, before being submitted to DRMS. The Division should be notified within 30 days if any groundwater monitoring wells are damaged or destroyed during the life of the permit. Damaged or destroyed wells should be appropriately repaired or replaced as soon as reasonably possible to preserve data comparability, and the Division notified when this is complete. The notification shall include details of any repairs or new well construction summary. If an existing monitoring well requires removal or relocation for any reason, the justification and proposed new well location should be provided to DRMS as a technical revision for approval prior to the removal of the existing well. 1.2.2. Baseline Groundwater Quantity Baseline water level data should be recorded in a table, and a narrative description of how the data was collected should be provided. A graph of the water level against time at each monitoring point should also be included. In most cases a static water level can be measured u sing a depth gauge from the top of the casing, however if the aquifer is under confined conditions, and the pressure is such that the well is flowing, an alternative method will be n ecessary (for example: https://www.usgs.gov/media/videos/measuring-water-levels-a-flowing- well ). The potentiometric head at the well can be readily derived from the depth to water measurement and the casing elevation. Head measurements from three or more points may be interpolated to give a groundwater flow direction and an approximation of the potentiometric surface in the aquifer. In many cases it will be necessary to collect more data points to adequately characterize the pre -mining conditions. Often a numerical model (for example: Modflow) will be an appropriate tool to characterize the hydrogeology of the site. In other cases, the Division acknowledges, routine one-dimensional groundwater equations may be appropriate to evaluate potential offsite hydrologic impacts. If a n umerical model is used, it should be thoroughly documented, with all assumptions explicitly stated. The documentation should include: • An explanation of the conceptual model, with assumptions explicitly stated • A detailed description of the model grid, with figures Sampling and Analysis Plan Guidance Page 7 of 12 September 2024 • A list of parameter values for boundary conditions and initial conditions • Details of the model calibration 1.2.3. Baseline Groundwater Quality A table should be provided with a complete list of water quality parameters to be measured. This will comprise both field parameters and laboratory analytes. The full parameter list should be based on Tables 1-4 from Regulation 41: The Basic Standards for Groundwater (Reg. 41). Selected parameters from these tables have been compiled in Appendix A for Construction Materials sites and Appendix B for Hard Rock sites. unless modifications are approved by the Division. It will be up to the Operator/Permittee to submit a Technical Revision with proper justification to reduce the analyte list. The Division will entertain variances from the Reg. 41 list on a case -by -case basis, but any proposed variance must be justified. Baseline groundwater quality data should be recorded in a table, with the sampling date. Minimum, maximum and average values for each parameter should be given and any exceedance of a standard shall be clearly identified. 2 Predicted Impacts to Hydrologic Balance Following the characterization of baseline conditions a prediction should be made as to the possible impacts of the proposed mining operation on groundwater quantity and quality. The prediction of likely impacts to groundwater quantity should include a prediction of the maximum spatial extent of drawdown caused by dewatering, or of mounding caused by impermeable cell liners/slurry walls, and the time -scale over which it will be observed. The extent and time to recovery to a steady-state following reclamation should also be predicted. The prediction of impacts to groundwater quality should include a discussion of water quality parameters that may be elevated as a result of the proposed operation, and the likely spatial and temporal extent of the impact. It is noted here that HB 19-1113, which applies to Hard Rock Sites only and was signed into law on April 4, 2019, requires most reclamation plans to demonstrate, by substantial evidence, a reasonably foreseeable end date for any water quality treatment necessary to ensure compliance with applicable water quality standards. If a numerical model is used to inform any of the hydrologic predictions the model should be thoroughly documented, as discussed in Section 1.2.2. 3 Groundwater Monitoring Plan A monitoring plan sufficient to verify the predictions of hydrologic impacts should be proposed. The Sampling and Analysis Plan Guidance Page 8 of 12 September 2024 locations of sampling points, and the frequency at which they will be sampled should be specified. A complete list of groundwater quality parameters to be sampled for should be given. A description of sampling methods should be included in sufficient detail to ensure that the procedure can be replicated throughout the life of the permit (Sampling Methods are discussed in more detail below). A commitment should be made as to how the monitoring data will be reported to the Division. Typically monitoring data will be compiled into a report, to be submitted by a specified date, e.g. annually or quarterly. The groundwater monitoring report will include: • Tabulated data for all parameters • Graphs/plots for selected parameters • A narrative analysis of the data, with trends and anomalies identified • A comparison of the observed data to the predictions and to the groundwater quality standards (see below) The requirements of the groundwater monitoring plan may continue to apply until final bond release and termination of jurisdiction. Changes to the groundwater monitoring plan will require a Technical Revision to the permit. 3.1. Groundwater Points of Compliance It is likely that one or more Groundwater Points of Compliance (POC) will be established, these are locations at which compliance with the applicable standard will be assessed. Detailed guidance on POCs has been given in the Groundwater Monitoring and Protection Technical Bulletin of November 19, 2019, and will not be repeated here. POCs should be identified in the groundwater monitoring plan. 3.2. Groundwater Quality Standards As is discussed in detail in the Groundwater Monitoring and Protection Technical Bulletin of November 19, 2019, the Division does not have the authority to set groundwater quality standards, but it does have both the authority and the obligation to apply the standards set by the Water Quality Control Commission, (in practice, this often involves the determination of how the Interim Narrative Standard from Reg. 41 should be applied at a site). For the sake of clarity, the numerical values for groundwater quality parameters that represent the applicable standard should be agreed and recorded in a table at the same time the POCs are established. 4 Sampling Methods The goal of sampling is to make accurate, repeatable field measurements and to collect representative groundwater samples for laboratory analysis. There is no single correct method to conduct groundwater Sampling and Analysis Plan Guidance Page 9 of 12 September 2024 sampling, however there many incorrect methods. Follow accepted best industry practices to ensure that a representative sample is collected and analyzed. Applicable references include those from the US Environmental Protection Agency, and the US Geological Survey. It is likely that the contracted analytical laboratory will supply detailed instructions for sample collection and handling. Best practices for sampling: • Details of sampling events should be recorded —documentation is critical for Quality Assurance • All samples should be collected on the same day, if possible • Sampling should occur in a progression from upgradient to downgradient wells • Depth to water should be measured first • Field instruments should be calibrated according to manufacturer's specifications prior to use • Field parameters (temperature, pH, conductivity, dissolved oxygen) should be measured and recorded before and after each purge of the well • A well should be purged at least three times before samples are collected for lab analysis; if field parameters vary by >10% between consecutive purges, purging should continue up to six times • Samples should be collected in the appropriate container and handled in a manner appropriate for the analysis • Manufacturer's instructions for the correct use and disposal of equipment should be followed • Ship samples well before the holding time is up; ideally, within 24 hours of sample collection • Do not leave sampling devices in monitoring wells for reuse Sampling and Analysis Plan Guidance Page 10 of 12 September 2024 References DRMS Groundwater Monitoring and Protection Technical Bulletin: November 19, 2019 https://drive.google.com/file/d/121Uc KmuAx7xhc8heQcROPnK u-kcG-J/view?pli=1 Well Construction Rules https://dwr.colorado.gov/services/well-construction-inspection Modflow Documentation https://www.usgs.gov/mission-areas/water-resources/science/modflow-and-related-programs Water Quality Control Commission regulations https://cdphe.colorado.gov/water-quality-control-commission-regulations EPA Groundwater Sampling Methodology https://www.epa.gov/sites/default/fi les/2015-06/documents/Groundwater-Sampl i ng.pdf USGS National Field Manual for the Collection of Water -Quality Data https://www.usgs.gov/mission-areas/water-resources/science/national-field-manual-collection-water- quality-data-nfm#overview HB 19-1113: Protect Water Quality Adverse Mining Impacts https://leg.colorado.gov/bi Its/hb19-1113 Sampling and Analysis Plan Guidance Page 11 of 12 September 2024 Appendix A: Full parameter list for Construction Material Sites (with Table Value Standards) from Regulation 41, Tables 1-4 Analyte Table (mg/L, Value unless given) Standard other units Reg. 41 Reference Table (1-4) pH Field (pH unit) 6.50 - 8.50 2 and 3 TDS 400 mg/L, background or 1.25X 4 Chloride - Dissolved 250 2 Fluoride - Dissolved 2 3 Nitrate (NO3) 10 1 Nitrite (NO2) 1.0 1 Nitrite + Nitrate as Nitrogen 10 1 Sulfate - Dissolved 250 2 Aluminum - Dissolved 5 3 Antimony - Dissolved 0.006 1 Arsenic - Dissolved 0.01 1 Barium - Dissolved 2 1 Beryllium - Dissolved 0.004 1 Boron - Dissolved 0.75 3 Cadmium - Dissolved 0.005 1 Chromium - Dissolved 0.1 1 and 3 Cobalt - Dissolved 0.05 3 Copper - Dissolved 0.2 3 Iron - Dissolved 0.3 2 Lead - Dissolved 0.05 1 Lithium - Dissolved 2.5 3 Manganese - Dissolved 0.05 2 Mercury - Dissolved 0.002 1 Molybdenum - Dissolved 0.21 1 Nickel - Dissolved 0.1 1 Selenium - Dissolved 0.02 3 Silver - Dissolved 0.05 1 Thallium - Dissolved 0.002 1 Uranium - Dissolved 0.0168 to 0.03 1 Vanadium - Dissolved 0.1 3 Zinc - Dissolved 2 3 These analytes, at a minimum, will be tested for during the five (5) consecutive quarters, or more, of baseline monitoring.

COLORADO Division of Reclamation, Mining and Safety Department of Natural Resources Date: May 30, 2025 To: Joel Renfro, DIMS CC: Amy Eschberger, DRMS From: Ben Hammar, DRMS RE: Cogburn Sand and Gravel and Reservoir Project, File No. M2025016 New 112c Application Joel, As requested, I have reviewed the requested sections of the Cogburn Sand and Gravel Reservoir Project application, DRMS permit No. M2025016, created by American Water Services, LLC (AWS) on behalf of Raptor Materials, LLC (Operator). The purpose of this memo is to quickly summarize AWS' report methodologies, analyses, and recommendations in relation to the Rules and requirements of the Division of Reclamation, Mining & Safety (DBMS), and to address portions of their geotechnical analysis and reclamation plan which are inadequate based on Rules 3.1.5 (3) and 6.5. Questions and comments regarding the requested sections meant to ensure all Rules and requirements are satisfied will be summarized at the end of this memo. Geotechnical Analysis Overview As noted earlier, this memo will address the sections of the Cogburn Sand and Gravel Reservoir Project application requested by Joel Renfro, the geotechnical analysis associated with the currently proposed reclamation plan for the Cogburn Project. A summary of the reclamation plan is included to provide context for the broader discussion of the analysis. Per information provided by Joe Renfro and the current proposed reclamation plan, the Operator intends to mine to a maximum depth of 35 feet, and following the completion of mining will adhere to a maximum slope of 1.25H:1 V on slopes less than 30 feet below the ground surface, and 3H:1 V below 30 feet. These slopes will then be lined with a clay liner to support the planned post -mining land use of a developed water resource. These slopes are the subject of the provided geotechnical analysis. AWS provided a slope stability analysis on behalf of the Operator, which primarily used material property information generated by a 2023 geotechnical study performed by Engineering Analytics, Inc. AWS also stated that their unit weight for the overburden clay and bedrock material used in the analysis was taken from information generated by DRMS. As DRMS does not typically perform material property testing, more information regarding the source of these values should be requested. 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us Jared S. Polls, Governor I Dan Gibbs, Executive Director I Michael A. Cunningham, Director AWS used four assumptions during their analysis, all of which were directly based on the planned reclamation plan. Their assumptions were as follows: • The static depth to groundwater with no pumping influence is 6 feet below ground surface and the water table will intersect the pit bank just above the mine floor (seepage face) during steady state dewatering; • The pit depth will vary between 23 and 50 feet below grade; • The termination zone for the 23 -foot simulation was placed 1.5 feet back from the crest of the mine wall as the model predicted sheet failure (raveling) for any termination zone beginning down the mine slope; During extraction activities the pit bank slope will vary between 1.25H:1 V and 3 H:1 V. All assumptions appear to be reasonable and required to accurately depict the planned conditions. PC-STABL, a typical geostability analysis software, was used to perform the slope stability analysis. Two cases were studied; one which represented worst -case conditions under only a 1.25H:1 V slope and the other with a mix of 3H:1 V and 1.25H:1 V conditions. The provided cases appeared to be reasonable and representative of the site conditions, however, no cases were provided for the slopes under seismic conditions. Per Rule 6.5 and other considerations related to this to be discussed later in this report, DMRS should require additional cases showing an adequate factor of safety (FoS) under seismic conditions. An additional point of discussion for this analysis is that of their chosen failure criteria, a FoS of 1.3. Per the requirements of the Mined Land Reclamation Board (MLRB), a FoS of 1.3 is required when a given site is located near critical structures such as utility lines, pipelines, infrastructure, etc. The FoS of 1.3 is allowable under the condition that material strength data was taken from lab testing of material obtained from the site. If assumed data was used, the required FoS is 1.5 for sites located within 200 feet of critical structure. This creates reason to scrutinize AWS' analysis for two reasons. The first is that assumed values were used in their analysis which had a nebulous source. This could potentially be an issue, however the materials used with assumed values aren't likely to have a significant impact on the slope's stability. The overburden clay and bedrock layers are unlikely to be the locations of a significant slope failure in these cases, and so it is the opinion of the Division that a FoS of 1.3 is acceptable to use in this case. The second issue is related to critical structures. While a FoS of 1.3 is acceptable for a site near critical structures or otherwise, is unclear if there are critical structures, primarily pipelines based on the information provided by the Operator, within 200 feet of the site. As this information has a significant effect on how conservative of a FoS must be used, it should be provided by the Operator. Recommendations In general, the analysis performed by AWS was performed using acceptable assumptions for the case that was studied. Some clarification should be requested to confirm their cases are adequate to meet the FoS requirements of the MLRB. As such, the following comments should be integrated into an adequacy letter: 1. Per Rule 6.5(3), please provide an additional slope stability analysis which demonstrates an adequate Factor of Safety under seismic conditions for both presented cases. Per the policies of the Mined Land Reclamation Board, a factor of safety of 1.15 under seismic conditions is the requirement for this case. 2. Per Rule 6.3.5(2)(e), please provide the location of any significant man-made structures within 200 feet of the permit boundary. This information should be used to assess if critical structures are near the permit and determine what Factor of Safety is adequate for the geotechnical analysis . This concludes my review of the requested sections of the Cogburn Sand and Gravel Reservior Project application, created by AWS on behalf of Raptor Materials, LLC.
