June 5, 2024 CIVCO Engineering, Inc. 1256 West 400 South Ste 1 Vernal, Utah 84078 Attention: Bret Reynolds, PE Email: bretreynolds@civcoengineering.com Subject: Geotechnical Services (Revised Letter) Pad Subgrade Permeability and Bearing Capacity Evaluation Approx. 40.135548°, -110.148151° Duchesne County, Utah SNOWSHOE Project No. 24037 Snowshoe Engineering Company (SNOWSHOE) was asked to perform a subsurface investigation at an existing unloading pad to collect samples for laboratory testing and to evaluate the subgrade materials (upper 10 feet adjacent the pad) potential bearing capacity. SNOWSHOE was also asked (after the initial scope of work was developed) to review documents by the client and provide our professional opinion concerning the potential that contaminated water (originating from material delivered to the site) could seep into underlying subsurface water in facility areas used for staging and dewatering activities. CURRENT PAD USE The existing concrete pad is used to unload imported material (soil). The material is then removed from the pad using front-end loaders or other similar equipment and processed in nearby areas. PROVIDED DOCUMENTS SNOWSHOE was provided documents by the client (Civco Engineering, Inc.) in an email delivered on May 17, 2024. The documents are provided in the Appendix and include: Soil Report - NRCS Ground Water Analysis (Includes Boring Logs) - Civco Engineering, Inc.

GEOLOGICAL SETTING Geological mapping (Duchesne and Kings Peak Quadrangles, Bruce Bryant) indicates surface soils in the area likely consist of the following: Glacial Outwash of Pre-Bull Lake Age (Pleistocene) Poorly sorted gravel and sand in terraces graded to pre-Bull Lake moraines. The mapping also indicates near surface or at surface bedrock in the area likely consist of the following: Upper Member of the Uinta Formation (Eocene) Gray mudstone and a few thin beds of sandstone and limestone. Dominantly alluvial in origin but contains some lacustrine beds. FIELD INVESTIGATION AND SUBSURFACE CONDITIONS SNOWSHOE conducted subsurface exploration at the site on May 17, 2024. A CME 75 geotechnical drill rig was used to drill two borings at the locations indicated on Figure 1. The borings were advanced using hollow stem augers (HSA). Samples were obtained using a split-spoon sampler. The subsurface conditions encountered in the borings consisted of varying depths of fill overlying lean clay with varying amounts of sand. Subsurface water was not encountered within the depths of our borings. Subsurface water depths will vary over time and with fluctuating surface water conditions. Boring logs illustrating the subsurface conditions encountered are provided on Figure 2 with material descriptions and legend provided on Figure 3. LABORATORY TESTING Full laboratory test results are provided with this letter on Table 1 and in the Appendix. A summary of the laboratory results for the two samples tested for hydraulic conductivity are as follows: Boring B2 @ 4 ½’ Classification: Lean Clay (CL) Water content: 9% Dry Unit Weight: 90 pcf Minus No. 200 Sieve (Silt/Clay): 71% Liquid Limit: 26% Plasticity Index (PI): 12 Hydraulic Conductivity: Average K b : = 7.8E‐05 cm/sec P A D S U B G R A D E P E R M E A B I L I T Y A N D B E A R I N G C A P A C I T Y E V A L U A T I O N C I V C O E N G I N E R I N G , I N C .

The suitability of the slab to support heavy equipment is highly dependent on the slab thickness, reinforcement and subgrade preparation. Surface Water Seepage - Concrete Pad Dewatering Areas We understand that dewatering procedures initially take place on the concrete pad at the facility. A concrete pad in good condition would restrict seepage of fluids from the surface to the underlying soil more effectively than a soil having a permeability of 1E-07 cm/sec. Surface Water Seepage – Other Staging and Dewatering Areas We also understand material having varying levels of saturation is subsequently moved to other areas at the site. Based on the provided documents, 12 borings were drilled on August 23, 2013 at the site. According to our interpretation of the boring logs, the subsurface soil consisted generally of clay, silt, sand and gravel. Bedrock was encountered below the soil in some of the borings according to the logs including Boring Borhole #1 which is the closest boring to the unloading and dewatering concrete pad. It is possible that deeper layers in other borings identified as soil are in fact bedrock. The logs also indicate that no subsurface water was observed in the upper 50 feet of any of the 12 borings. Our opinion is based on the above information and the following assumptions made after review of the provided documents: a) the provided logs are accurate, b) our interpretation of the logs is accurate, c) the subsurface water observations reported in the logs are accurate and, d) conditions are the same now as reported in 2013.

APPENDIX United States Department of Agriculture A product of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local participants Custom Soil Resource Report for Duchesne Area, Utah, Parts of Duchesne, Utah, and Wasatch Counties Natural Resources Conservation Service February 10, 2023 Preface Soil surveys contain information that affects land use planning in survey areas. 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.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_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 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 6 identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. Custom Soil Resource Report 7 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 9 Custom Soil Resource Report Soil Map 44 4 1 0 0 0 44 4 1 6 0 0 44 4 2 2 0 0 44 4 2 8 0 0 44 4 3 4 0 0 44 4 4 0 0 0 44 4 4 6 0 0 44 4 5 2 0 0 44 4 5 8 0 0 44 4 1 0 0 0 44 4 1 6 0 0 44 4 2 2 0 0 44 4 2 8 0 0 44 4 3 4 0 0 44 4 4 0 0 0 44 4 4 6 0 0 44 4 5 2 0 0 44 4 5 8 0 0 571000 571600 572200 572800 573400 574000 574600 571000 571600 572200 572800 573400 574000 574600 40° 9' 37'' N 11 0 ° 1 0 ' 2 ' ' W 40° 9' 37'' N 11 0 ° 7 ' 2 2 ' ' W 40° 6' 54'' N 11 0 ° 1 0 ' 2 ' ' W 40° 6' 54'' N 11 0 ° 7 ' 2 2 ' ' W N Map projection: Web Mercator Corner coordinates: WGS84 Edge tics: UTM Zone 12N WGS84 0 1000 2000 4000 6000 Feet 0 350 700 1400 2100 Meters Map Scale: 1:24,400 if printed on A portrait (8.5" x 11") sheet.

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 Custom Soil Resource Report 11 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 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 Custom Soil Resource Report 12 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.

Initial notifications will be emailed to each customer’s payables department with instructions to forward to all supervisors responsible for high liquid waste disposal. 2. After the initial notifications we will email directly to all supervisors of waste generators and to all hydro- excavator operators frequenting EEI. 3. EEI personnel interacts with delivering hydro-excavator operators on a daily basis, allowing for communications required under R315-303-3[1.1][a][iv]. 5' 3:13:1 COMPACT BERM TO 90% MDD BERM DETAIL 2'-4' NOT TO SCALE CI V C O E n g i n e e r i n g , I n c .
