Equipment used on the site includes Front End Loaders (2), Dump Trucks (2), Backhoe (1), Farm Tractor (1) and miscellaneous discs, rippers, tillers. Surface Water The Bridgeland Quadrangle map shows an intermittent stream located approximately 950 feet southwest and 528 feet northwest of the project. These stream beds consist of desert shrub vegetation. There is an irrigation canal 4,488 feet northwest of the project. The streams and canal are at a lower elevation than the project. See attached water and contour map. Storm Water Annual precipitation for the project area is below 10 inches per year. See attached precipitation map. 1.0 OPERATIONS PLAN 1.1 SCHEDULE OF CONSTRUCTION The 140 =/- acre property has been operated as a bio-remediation land farm since 2011. The proposed facility is sectioned into 12 10 acre =/- cells plus a 10 acre area for operations, parking, office, and water tank battery. A 2-to-8-foot berm will surround each cell with slopes no steeper than 33% to prevent storm water from entering or leaving each cell. Berms are constructed from existing site soils excavated from the property. A detail of the EEI Facility berm is attached in the solid separator drawing. Page 12 To the south, adjacent to the facility will be a waste staging area where waste delivered to the site will be inspected and treated, if necessary, prior to disposal. Waste that requires treatment will be processed in a waste concrete holding area designed to protect ground water from possible waste contamination. Drawing details of the waste staging area are attached see the solid separator drawing. At the start of operations, EEI anticipates approximately 70 cubic yards of E & P waste will be transported to the proposed facility per day. EEI is considering using several different products and processes to stabilize the waste. Some of the products that may be used for mixing and stabilizing the waste include but are not limited to sawdust, native soils, lime, potash, or remediated soils from any of the 11 cells currently not in use receiving waste. EEI may also process the waste to remove liquids by drying the waste in the concrete storage area. Waste acceptance procedures and quality control of waste being disposed in the facility are outlined in sections 1.2.1 and 1.2.2 of this report. Each of the 10-acre cells will be filled to closure capacity one cell at a time. Once the final process is defined adjustments to the design life of the facility will be made. At this point the life duration of the facility is defined assuming that half of the waste arriving at the facility will be mixed with remediated soil and the remaining waste will be processed using other equipment [mixing, drying] and then placed directly into one of the facilities cells. Waste that will be mixed with additional material will need to reach a moisture content that is workable. In order to obtain an estimate for the mixing ratio, a preliminary waste assessment was conducted using samples of anticipated types of waste and remediated soils that will be disposed of in the EEI facility under this permit application. During this assessment it was determined that the mixing of remediated soils with waste when needed will be done at a ratio of approximately 1.5:1 respectively, in order to reach a waste moisture content that will be suitable to be spread on the site. In other words, for every 1 Cu. Yd. of waste there will be approximately 0.5 Cu. Yds. of remediated soils added to reach a moisture content that is workable. Based on waste mixing assumptions described above and assuming waste will be accepted 6 days per week with a 10% growth rate over the life of the facility up to 50,000 cubic yard per year, the projected life of the cell #7 is approximately 8 years. However, the projected life may increase or decrease based on the type of processing and/or mixing methods utilized. A copy of the spreadsheet used to calculate this estimated life is included in the closure plan. All assumptions presented in the previous paragraphs were used in the spreadsheet calculations. 1.2. DESCRIPTION OF WASTE HANDLING PROCEEDURES The following sections describe the general procedures that will be followed under this permit application for accepting, disposing, recording, and excluding waste at EEI. 1.2.1 General Procedures All waste will be hauled to EEI using commercial or independently owned trucks. All trucks will enter at the main gate and check in with the EEI facility office. Every truck load of waste will be inspected for liquids and inappropriate waste prior to disposal. Waste that appears to be stable, free of liquids, will be directed to the appropriate cell for placement. Waste that is unstable, has excessive liquid Page 13 content, will be placed on the concrete pad for further processing. The concrete pad is designed to separate liquids from solid waste. The liquids drain off into lined holding ponds. Liquids are then collected and loaded into a vacuum truck and sprayed onto a dry cell. After the solid waste has been separated from the liquid waste and mixed with other solid materials, the solid waste will be removed from the concrete pad and then placed in the cell using heavy equipment or a conveyor system. All waste will then be placed in a uniform layer in the cell. 1.2.2 Waste Shipment Records The EEI facility operation manager will maintain and store waste shipment records as part of the daily record of disposal activity. Each truck load of inbound waste will have a load ticket completed by the truck driver and verified by the EEI facility operating staff. An example of the load ticket is included below. See Figure 1. Figure 1 Page 14 1.2.3 Waste Disposal Waste deposited will be placed in 1 ft. thick lifts and compacted to reach a firm and unyielding surface to maximize facility capacity. EEI will distribute inbound waste to the cell until the capacity of the cell has been reached. Closure of the cell will occur at that time and EEI will stop disposing of waste in this cell. 1.2.4 Plans for Excluding Waste Non-hazardous waste including E&P waste will be accepted at the EEI facility as allowed as directed by DWMRC. To ensure that waste meets this requirement, all potential waste generators disposing of waste at EEI proposed facility must first complete a waste profile assessment to determine the acceptability of the waste according to this permit application. Representative samples of each type of waste will be provided to EEI by all generators for testing. Generators will provide a waste characterization form certifying that it meets the requirements of disposal from all sources. Generators will be required to inform EEI when composition changes and then resubmit a waste characterization form with samples. 1.3. WASTE FACILITY INSPECTION AND MONITORING EEI personnel will inspect the proposed facility to avoid operator error and discharges which may cause or lead to the release of waste to the environment or to a threat to human health. Facility inspections will be conducted weekly. 1.3.1 Fugitive Dust Control As part of the daily operations of the proposed facility, fugitive dust will be monitored, and controls will be put in place as deemed necessary by the Operations Manager. These sources of dust will be controlled by watering and proper placement of waste in the facility. EEI staff will be trained in monitoring opacity and checking the facility for dust control issues. When opacity of the dust exceeds 20%, watering controls will be affected on the facility haul roads, waste cells, and common areas. 1.3.2 Plan for Litter Control EEI does not anticipate accepting waste materials that will cause a wind-blown litter problem. EEI will complete a daily inspection of the facility and the surrounding area to identify a potential litter problem. EEI does not anticipate waste that would be considered a disease vector. 1.3.3 Contingency Plan for Fire or Explosion In the event of a fire or explosion the EEI manager will contact local emergency authorities to initiate an emergency response. A list of the local responders is provided, see Figure 2. Page 15 1.3.4 Alternative Waste Handling Plan In the event of a facility closure due to an emergency or repairs, EEI will make arrangements to have the waste re-directed to other DWMRC landfills in Duchesne County or the Duchesne County Landfill located at 20550 W and 2000 S. 1.3.12 General Training Plan (R315-302-2(2)(o) EEI currently has a training program to educate employees on handling waste and operating existing equipment at the EEI waste facility as required in R315-302-2[2].

To ensure that waste meets this requirement, all potential waste generators disposing of waste at EEI proposed facility must first complete a waste profile assessment to determine the acceptability of the waste according to this permit application. The area served by the facility includes the following: • West boundary – Wasatch Front • East boundary - Colorado Border • North boundary - Wyoming border • South boundary - Book Cliffs Phone (435)789-5448 * Fax (435)789-4485 Email: civco@civcoengineering.com Page 42 TAB 6 POST CLOSURE & CLOSURE PLAN Page 43 ENVIRONMENT ENERGY INNOVATIONS PLEASANT VALLEY, UTAH Cell #7 landfill @EEI CLOSURE DESIGN PLAN Introduction At the end of the life of Cell #7 of the Environmental Energy Innovations, LLC (EEI) facility the cell will be closed according to R315-302. The following is a brief plan for closure of the cell and is subject to amendment if conditions and circumstances justify an amendment. Closure Procedures The following procedures will be followed: 1.Notify the Executive Secretary of intent to close 60 days prior receipt of final material. 2.Commence closure procedures within 30 days of receipt of final material. Closure activities will be completed within 180 days of commencement of closure activities. 3.Within 90 days of completion of closure activities, submit a copy of the closure plan and certificate that closure has been performed per the closure plan. These must be stamped and signed by a State of Utah Licensed Professional Engineer. Closure Schedule Sixty days prior to the expected final receipt of waste for Cell #7, EEI will notify the division of their intent to begin closure operations of the cell. EEI will begin the closure operations after the final receipt of waste is obtained. It is anticipated that each closure operation will take place over an anticipated duration of 90 to 120 days. During this period, the EEI facility cell will be graded, covered, and surveyed. As-built plans will be generated for reference for the final inspection by the division. Design of Final Cover The final cover will consist of two soil layers meeting the requirements of R315-303-3(5). The first layer will consist of at least 18 inches of compacted soil, or equivalent, with a permeability of 1 x 10-5 cm/sec or less, or equivalent with surface slopes grades not less than 2% and the side slopes grades not more than 33%. The second layer will consist of at least six inches of soil capable of sustaining vegetative growth and seeded with grass, other shallow rooted vegetation, or other native vegetation. Markers or other benchmarks shall be installed in any final earthen cover to indicate the thickness of the final cover. Page 44 Capacity of EEI Facility Based on the assumption of half the waste being mixed with additional material, the estimated capacity of cell #7 up to the final cover is approximately 343,000 cubic yards of waste plus mixing material. This calculation accounts for an estimated dry density of 135 lb./cu-ft for the mixing material. A table with the projected life at 10 percent growth rate, capped at 50,000 cubic yards of waste plus mixing material per year, for the EEI facility is provided in Table 1 below. The growth rate is defined as the number of trucks delivered to the site on an average daily basis. It will take eight years for the cell #7 to be completed at the expected growth rate. With an increase in the growth rate, the life of cell #7 of the EEI facility will be reduced.

EEI will notify the division of the anticipated date of completion and plan for scheduling the inspection. POST CLOSURE CARE Immediately after the completion of construction for the final cover of cell #7, the post closure care plan will be implemented. As required in R315-302-3(5) the post closure care activities will take place for 30 years or as long as the Director determines is necessary for the facility or unit to become stabilized and to protect human health and the environment. A licensed engineer with the state of Utah will direct the post-closure care of the facility and will provide EEI with recommendations to properly maintain the EEI facility and prevent any release of harmful substances. The engineer will also provide the division with documentation if he determines that the site is safe to reduce or discontinue site monitoring prior to the end of the 30-year period. During the post closure period the following activities will take place: Site Monitoring: EEI personnel will be on site weekly to monitor activities at the proposed EEI facility and restrict access to Cell #7. Access to the Cell #7 will be restricted with fencing and gates. Signs will be posted advising of the potential dangers associated with cell #7. Only authorized personnel of EEI Page 45 will have access to cell #7 site. Markers or other benchmarks installed as part of the closure plan will be observed during each quarterly inspection and the earthen cover shall be raised to the appropriate thickness as necessary. Erosion channels deeper than 10% of the total cover thickness shall be repaired as soon as possible following their discovery. On a quarterly basis the EEI facility cover will be inspected to check for rutting and depressions that could result in rapid erosion. If rutting or depressions in the cover are identified, they will be repaired by grading and seeding the surface. Slopes of the final cover will also be inspected and maintained. EEI will ensure that a 2% slope will be maintained on the top of the cover and a 3:1 slope will be maintained around the perimeter of the cell. Run-off water from the final cover will be directed into the existing drainages to the north and west of the cell. EEI will on a Quarterly basis inspect the run-off collection system and ensure that they are properly diverting water into the existing storm water drainages. Repairs will be made as needed. Surface and Ground Water Monitoring: No samples of surface waters will be collected because there are no observed streams, springs, or other surface waters at the site of the proposed EEI facility. Ground water will not be sampled as the test holes taken did not encounter groundwater. Record of Title, Land Use, Zoning The Duchesne County Recorder will be notified during the final closure period of the entire facility. The county recorder will be provided with documentation and plats of the location of the disposal site. Notification of the closure, and location of the EEI facility will also be sent to the county recorder and zoning changes will be made if necessary. Documentation of the history of the EEI facility permanently appended to the title of record and land use restrictions will be put in place.

The closure cost for the EEI facility is based on the cost of the placement and grading of 18 inches of compacted soil, or equivalent, with a permeability of 1x10-5 cm/sec or less, or equivalent placed upon the final lifts and a 6-inch topsoil layer and seeding of topsoil. Closure cost estimates were obtained from an independent contractor. Upon closure of all cells the parking area, office spaces, and loading and unloading facilities will be removed and the area graded, topsoil layer added and seeding of topsoil to provide a natural looking surface. The cost of doing this work is estimated at $20,000. The closure cost of cell 7 is $1,055,000 as shown in Table 1. Closure Cost for Cell 7 Task Description Total Cost Details Closure Cost Per Cell Letter of Notification of Closure $2,000 Letter to DWMRC and County Cover and Topsoil Material $1,020,000 Seeding/Mulching $8,000 Contingency $25,000 Total Cost Per Cell $1,055,000 Table 1 Closure Costs POST CLOSURE CARE COSTS Post closure care of inactive sections of the EEI facility will consist of maintaining the integrity of the final and vegetative covers. Any areas subject to erosion will be corrected and appropriate measures will be implemented to identify and eliminate the run-on source. No active or technical devices are proposed for at the EEI facility. Best management practices will be implemented to minimize infiltration and assure the integrity of the run-on/run-off system. An evaluation of the system will be made during the quarterly inspections and corrective measures if any will be implemented. All run-on and run-off from events smaller than the 25-year storm will be controlled through drainage design. Post closure care costs are estimated by the cost of maintaining the previously described activities for a 30-year period. The estimated cost of the post closure care tasks is approximately $31,000 for cell 7 as shown in Table 2.

DUCHESNE COUNTY, UTAH SOIL ENVIRONMENTAL ENERGY INNOVATIONS Page 71 Page 72 Page 73 Page 74 Page 75 Page 76 TAB 12 HIGH WET WASTE MANAGEMENT PLAN Page 77 R315-302-2 [2] [b] Two different processes must occur upon waste delivery at EEI. DRY Waste Dry waste delivered in side dumps, dump trailers, and belly dumps is considered dry waste generally with a moisture content ranging from 5% to 35%. These inbound loads are dry enough not to leak out of the trailers used for transport. EEI personnel checks with the drivers as the first step toward determining if the waste is non- hazardous and meets our permit requirements. Most explanations describe a spill cleanup, or drill cuttings along with the source location such as a well lease number, pipeline name, tank battery and the generator. The operator will physically inspect the waste looking for characteristics that support our decision to accept the load. If satisfied the load is dumped onto the dry unloading area where our operator can test moisture content with a meter to determine the soil mixing necessary to reduce the moisture content to 25%-35%. This calculation is based on the operator’s best guess but is checked by the manager after the soil mixing [done by front end loaders] is complete. Additional soil is often required to reach the 25%-35% threshold. When the manager is satisfied with the moisture content of the material, the waste material is loaded and delivered to cell #7 for spreading and compacting. Compacting is done by a tractor pulled spreader. WET Waste Wet waste is delivered in super suckers or vacuum tanks and are 40% - 50% water. Each super sucker’s vacuum tank is 40 bbl – 60 bbl capacity with the allowable fill at 80%. Therefore, each average load’s water content is: Ave. total load = 40 bbl. [50 bbl X 80%] Ave. water content = 20 bbl [50% X 40 bbl] Ave. daily estimated water delivered by super sucker, based on actual load counts from 9/20/23 – 11/4/23 = 179 bbl/day. Page 78 In addition to super sucker loads we receive loads on 110 bbl trailers occasionally. Adding the two together increases the average estimated daily water delivery to 200 bbl/day. Super Suckers are hydro excavators and offer a technology that sucks up liquid mixtures of oil field waste including tank bottom clean outs, pipeline clean outs, drilling rig clean outs, etc. These loads require an unloading site designed to separate water from solids and to confine the water in holding ponds until EEI can deliver it to cell #7. EEI’s unloading site is a concrete pad designed by engineers to utilize gravity to drain water off the solids portion of the load and hold the water while capturing the solids on the slightly sloping concrete pad. [See engineer’s design]. EEI can unload two trucks at one time. Our operator’s first step is to ask the delivery driver what type of waste he has to unload and to identify the well site origin. Our operator cannot physically inspect the load until the driver backs onto the pad and engages his pressure pump and opens his valves to release the load onto the pad. At this point EEI has to rely on the waste profile assessment provided by the waste generator and the driver’s verbal representation to make the determination that the load is in fact non-hazardous waste meeting the requirements of a class IIIb permit. Now the challenge becomes drying the wet solid waste down to a moisture content of 25%- 35%. This is accomplished by 2 processes. 1. The first process is the material is off loaded on to a sloping concrete slab where continual gravity induced force drains the water out of the solids and allowing it time to trickle down the concrete pad and into the holding ponds. This can take 1-2 days for each 24 hours of unloading wet super sucker loads. 2. After the water has drained sufficiently, the EEI operators deliver soil from any of the 11 inactive cells to the concrete pad to start the mixing process by front end loaders. Testing for moisture content is based on visual indications. When the manager gets a moisture reading of 25%-35% the waste material and mixing soil is released for spreading on cell #7. EEI employs an implement which thoroughly mixes as it spreads waste in approximately 2” lifts. The waste that is spread is dusty in 1-2 hours. Page 79 The holding capacity of the wastewater ponds is 8000 bbl. when empty. The ponds are usually ½ full providing approx. 4000 bbl capacity on any given day to handle the occasional high-volume day. The final process for disposal of WET waste is emptying the water from the holding ponds and spreading the water on cell #7 in a way that does not threaten ground water through runoff or absorption. Our process was approved by permit modification from UDOGM in 2022 and is as follows. EEI loads the water in a vacuum truck with a suction/ pressure pump and delivers to cell #7 where the operator will set the delivery volume low enough that the pressure induced spray wets only ¼ “ – ½” of the surface soil without delivering enough water to create a puddle. This volume of water evaporates quickly allowing dust to form, usually within 1 hour. Cell #7 is approximately 10 acres or 435600 SQ. FT. It takes 3230 bbl of water to cover cell #7 1/2“ deep. At our current rate of 1400 bbls per week EEI would spread ½ “ approx. twice per month. Page 80 CI V C O E n g i n e e r i n g , I n c .

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.

Boring B2 @ 8 ½’  Classification: Lean Clay (CL)  Water content: 12%  Dry Unit Weight: 102 pcf  Minus No. 200 Sieve (Silt/Clay): 72%  Liquid Limit: 34%  Plasticity Index (PI): 22  Hydraulic Conductivity: Average K b : 1.3E‐06 cm/sec CONCLUSIONS AND PROFESSIONAL OPINION Bearing Capacity Based on our field investigation and laboratory test results, an ultimate bearing capacity of 2,000 pounds per square foot (psf) could be assumed at typical shallow foundation depths at the locations investigated. 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 Page 90 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 Page 91 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 Page 95 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 Page 96 identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

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 Page 101 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 Page 102 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.
