A, B, C, & E of the Weld County Code) 1. Explain the proposed use and business name. ECO Services, LLC (ECO Services), is requesting a Use by Special Review (USR) permit for an oil and gas support and service business in the agricultural zone district, more specifically a containment liner company, as allowed by Section 23-3-40.V of the Weld County Code. The 9.53 -acre subject property is located in Part of the South Half of the Northeast Quarter of Section 32, Township 7 North, Range 64 West of the 6t' P.M., being Lot A of Recorded Exemption RECX17-0186. The subject property contains a 2,280 -square foot manufactured structure, 8,500 -square foot commercial shop, 8,700 -square foot greenhouse, 3,800 -square foot equipment building, one 300 -square foot storage shed, and one 600 -square foot utility building. ECO Services is proposing to relocate their existing operations from another site in the county to the existing 8,500 -square foot commercial building that is located on the southwest portion of the parcel and the 3,800 -square foot equipment building centrally located on the property. The 2,280 - square foot manufactured structure will be used as a caretaker residence. The 3,800 -square foot equipment building is expected to need a Change of Use to a commercial building and the permit application is requested to be a Condition of Approval to the USR. Access to the property is via Weld County Road (WCR) 53. The access location is shown on the RECX17- 0186 plat, a copy of which is included with this request for reference. The on -site operation will primarily be the fabrication and repair of secondary containment liners for use at oil and gas tank battery sites. The liners are made from polyethylene. Polyethylene will be delivered to the site in rolls of 30-40 mil sheets, so there will be no manufacturing of the raw material at this location. The majority of Eco Services' operations will occur off -site at various oil and gas locations around the county. The shop will primarily be used to store company equipment and vehicles. Vehicles that may be on -site include company trucks and employee passenger vehicles, trailers, and one semi - truck and trailer. The majority of the equipment is staged at the construction site and returned to the facility as needed. Parking inside the contractor's shop will occur 24 hours a day, seven days a week when employees are not taking the vehicles off -site for business. The primary hours of operation are 4:00 A.M. to 6:00 P.M., Monday through Sunday. ENGINEERING, PLANNING, CONSULTING & REAL ESTATE HQ & Mailing: 3050 67th Avenue, Suite 200, Greeley, CO 80634 1970-535-9318 office 1970-535-9854 fax Idaho: 213 Canyon Crest Drive, Suite 100, Twin Falls, ID 83301 1208-595-5301 www.agpros.com Page 2 of 9 2. Explain the need for the proposed use. ECO Services is a Northern Colorado -based business specializing in fabricating containment liners. The business provides containment liners for use at oil and gas production sites but could potentially be used in other sectors such as agriculture, municipality and special district needs, utilities, as well as private. Weld County recognizes mineral resources as vital to the state's economy. Oil and gas support service businesses are an important part of the mineral resource industry. 3. Describe the current and previous use of the land. The site is currently permitted under USR 19-0015 for hemp processing, storage, and distribution of extracted raw oil. ECO Services is proposing to relocate their existing operations from another site in the county to the existing 8,500 -square foot commercial shop that is located on the southwest portion of the parcel, the 3,800 -square foot equipment building centrally located on the property, and the existing 2,280 -square foot manufactured structure. No additional site improvements are proposed. 4. Describe the proximity of the proposed use to residences. The closest residences to the proposed USR boundary are both located approximately 200 feet east and southeast of the subject area. The access for the site is from WCR 53 and is not shared. There are three other residences located nearby approximately 1,100 feet north, 1,090 feet northeast, and approximately 1,160 feet southeast of the equipment building. 5. Describe the surrounding land uses of the site and how the proposed use is compatible with them. The subject property and the majority of the surrounding properties are in the Agricultural (A) Zone District. There is PUD zoning located southeast of the proposed operation. In addition to rural residential, rangeland, and oil and gas activities typically found in the A Zone, there are several USRs in the surrounding area. USRs in the vicinity of this site include dairy operations, Ag Service Establishments, water tank, group home, contractor's shop, and a church. The proposed containment liner shop is compatible with the surrounding land uses. There are multiple oil and gas facilities in the vicinity and the proposed use directly supports the oil and gas industry. Company and employee generated traffic is expected to be very minimal with up to 25 vehicles accessing the subject property each day. Other traffic to the site will be associated with the residential uses associated with the manufactured structure. The operation is not expected to produce nuisance noise levels or odors. Page 3 of 9 6. Describe the hours and days of operation (i.e. Monday thru Friday 8:00 a.m. to 5:00 p.m.). Parking and equipment storage inside the shop will occur 24 hours a day, 7 days a week, when employees are not taking the vehicles and equipment off -site for business. The on -site operations will primarily occur between 4:00 a.m. to 6:00 p.m., 7 days per week. Occasional operations outside of the primary hours may be required due to the oil and gas industry service needs. 7. Describe the number of employees including full-time, part-time and contractors. If shift work is proposed, detail number of employees, schedule and duration of shifts. It is expected that the operation will have 15-20 full-time employees. The expected work hours will vary based on job type. Off -Site Employees: There will be two shifts per day, from 4:00 a.m. to 4:00 p.m. and 4:00 p.m. to 4:00 a.m. Four employees per shift are expected; they will pick up their work trucks and then leave for off -site operations. Yard Employees: Expected work hours will be 6:00 a.m. to 6:00 p.m. Five to seven employees will be on site regularly; they may occasionally be off -site bringing tools, equipment, or products to the job sites. 8. Describe the maximum number of users, patrons, members, buyers, or other visitors that the site will accommodate at any one time. 15 employees are expected to access the site per day. As shift work is proposed, their trip times are staggered throughout the day. In addition, 2-3 delivery truck visits per week are expected. Due to the type of business, customers are not expected to come to the property. 9. List the types and maximum numbers of animals to be on the site at any one time (for dairies, livestock confinement operations, kennels, etc.) N/A. 10. List the types and number of operating and processing equipment. 1— Flat bed semi -truck 6 — Work pickup trucks 1 — Trailer 10-15 — Employee vehicles Page 4 of 9 11. List the types, number, and uses of the existing and proposed structures. The subject property contains a 2,280 -square foot manufactured structure, 8,500 -square foot commercial shop, 8,700 -square foot greenhouse, 3,800 -square foot equipment building, one 300 -square foot storage shed, and one 600 -square foot utility building. ECO Services is proposing to relocate their existing operations from another site in the county to the existing 8,500 -square foot commercial building that is located on the southwest portion of the parcel and the 3,800 -square foot equipment building centrally located on the property. The 2,280 - square foot manufactured structure will be used as a caretaker residence. 12. Describe the size of any stockpile, storage or waste areas. No storage or stockpiling of wastes is proposed on site at this time. There will be minimal outdoor storage associated with this use. 13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. The proposed use is not anticipated to produce nuisance debris, junk, or other wastes. A waste service provider will be used to dispose of excess materials and trash. 14. Include a time -table showing the periods of time required for the construction of the operation. The facility is existing; additional construction is not anticipated with this USR. 15. Describe the proposed and existing lot surface type and the square footage of each type (i.e. asphalt, gravel, landscaping, dirt, grass, buildings). A Drainage Report was prepared for USR19-0015 for the hemp processing operations. Since there is no proposed increase to the imperviousness of the site, the existing detention pond is expected to be sufficient for the proposed USR. A Drainage Narrative has been prepared and is included with this request. 16. How many parking spaces are proposed? How many handicapped -accessible parking spaces are proposed? 22 parking spaces are proposed. One handicap space and one large vehicle space for a semi - truck is provided. These are shown on the USR site plan. 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. The property has pipe fencing along the WCR 53 frontage and three -strand barbed wire around the remaining perimeter. No additional fencing is proposed as minimal outdoor storage for the on -site operations is expected. Page 5 of 9 18. Describe the existing and proposed landscaping for the site. A majority of the site contains native grasses. No additional landscaping is proposed. 19. Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity. Upon cessation of the Use by Special Review activity, equipment specific to the business will be removed. The existing structures will remain for residential or agricultural use. 20. Describe the proposed fire protection measures. Fire protection for the site is provided by the Galeton Fire Protection District (GFPD). A fire extinguisher will be kept on -site. In addition, there are several fire suppression tanks that were previously set on the property and approved by GFPD. It is anticipated that no additional fire protection measures will be necessary. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. The approval of this request would be consistent with Section 22-2-10 B. of the Weld County Code, which states "One of the basic principles upon which the United States was founded is the right of citizens to own and utilize property so long as that use complies with local regulations and does not interfere with or infringe upon the rights of others." The proposed use will not inhibit agricultural production or operations and is harmonious with the surrounding land uses. 22. Explain how this proposal is consistent with the intent of the zone district in which it is located. (Intent statements can be found at the beginning of each zone district section in Article III of Chapter 23 of the Weld County Code.) The A (Agricultural) Zone District is intended to provide areas for the conduct of agricultural activities and activities related to agriculture and agricultural production, and for areas for natural resource extraction and energy development, without the interference of other incompatible land uses. The proposed use supports the natural resource extraction and energy development occurring in Weld County. In addition, Article III of Chapter 23 of the Weld County Code lists oil and gas support and service businesses as a use allowed by special review outside of subdivisions and historic townsites. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. The subject property is not within any coordinated planning areas or growth management areas of any municipalities. Per the Weld County Comprehensive Plan Map, the site is outside of the Annexation, Urban, and Urban/Non-Urban areas, and is approximately 0.55 of a mile from the Weld County Opportunity Zone. As no subdivisions or zone changes are Page 6 of 9 proposed, the development classifications and proximity to the Weld County Opportunity Zone are not anticipated to be applicable to this proposal. 24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. The proposed use is expected to have minimal impact on the health, safety, and welfare of the inhabitants of the neighborhood and the County. Business -related traffic will be minimal, and operations will occur primarily in the shop buildings or off -site at specific job locations. A Nuisance and Waste Management Plan has been developed and is included with this request. 25. Describe any irrigation features. If the proposed use is to be located in the A (Agricultural) Zone District, explain your efforts to conserve prime agricultural land in the locational decision for the proposed use. There are no existing irrigation ditches or canals crossing this site. The improvements on -site are existing, and no new improvements are proposed on the undeveloped areas of the property. The site is not currently used for farming as it is too small to be economically viable as a commercial farm. 26. Explain how this proposal complies with Article V and Article XI of Chapter 23 if the proposal is located within any Overlay Zoning District (Airport, Geologic Hazard, or Historic Townsites Overlay Districts) or a Special Flood Hazard Area identified by maps officially adopted by the County. The site is not located within any Airport, Geologic Hazard, or Historic Townsites Overlay Districts. The subject property is not located in a Special Flood Hazard Area. 27. Detail known State or Federal permits required for your proposed use(s) and the status of each permit. Provide a copy of any application or permit. No state or federal permits are anticipated with this USR. The fabrication and repair of containment liners occurs primarily off -site at each job location. The on -site fabrication and repair of containment liners is expected to be well below the air pollution emission notice (ADEN) permit thresholds. Should an APEN be required, we would expect the following development standard for this project "The facility shall comply with the APEN permit requirements as stipulated by the air pollution control division of the Colorado Department of Public Health and Environment, as applicable." Should state or federal permits be determined to be required, it is requested to be a Condition of Approval to the USR. Page 7 of 9 Environmental Health Questions: (Chapters 14, 23, and 30 of the Weld County Code) 1. Discuss the existing and proposed potable water source. If utilizing a drinking water well, include either the well permit or well permit application that was submitted to the State Division of Water Resources. If utilizing a public water tap, include a letter from the Water District, a tap or meter number, or a copy of the water bill. There is a North Weld County Water District tap no. 3540 that currently supplies water service to the property. A copy of the water bill is included with this application. 2. Discuss the existing and proposed sewage disposal system. What type of sewage disposal system is on the property? If utilizing an existing on -site wastewater treatment system provide the on -site wastewater treatment permit number. (If there is no on -site wastewater treatment system permit due to the age of the existing on -site wastewater treatment system, apply for an on -site wastewater treatment system permit through the Department of Public Hearing and Environment prior to submitting this application.) If a new on -site wastewater treatment system will be installed, please state "a new on -site wastewater treatment system is proposed." (Only propose portable toilets if the use is consistent with the Department of Public Health and Environment's portable toilet policy.) There is an existing septic system, permit no. SP -0701062, that provides sewage disposal to the property. No change to the existing septic system is proposed. 3. If storage or warehousing is proposed, what type of items will be stored? The site is not proposed to be used for long-term storage or warehousing. 4. Describe where and how storage and/or stockpile of wastes, chemicals, and/or petroleum will occur on this site. The site is not proposed to be used for the storage and/or stockpiling of wastes, chemicals, other than the fuel storage described below. 5. If there will be fuel storage on site, indicate the gallons and the secondary containment. State the number of tanks and gallons per tank. There will be one 500 -gallon fuel tank located on -site for business needs, with both primary and secondary containment. 6. If there will be washing or vehicles or equipment on site, indicate how the wash water will be contained. Washing of vehicles or equipment is not proposed. Page 8 of 9 7. If there will be floor drains, indicate how the fluids will be contained. No floor drains are existing or proposed. S. Indicate if there will be any air emissions (e.g. painting, oil storage, etc.). The fabrication and repair of containment liners occurs primarily off -site at each job location. The on -site fabrication and repair of containment liners is expected to be well below the air pollution emission notice (ADEN) permit thresholds. Should an APEN be required, we would expect the following development standard for this project "The facility shall comply with the APEN permit requirements as stipulated by the air pollution control division of the Colorado Department of Public Health and Environment, as applicable."

Additional information may be requested depending on type of land use requested. Noted. Public Works Questions: (Section 8-11-40, Appendix 8-Q, and Section 8-14-10 of the Weld County Code) 1. Describe the access location and applicable use types (i.e., agricultural, residential, commercial/industrial, and/or oil and gas) of all existing and proposed accesses to the parcel. Include the approximate distance each access is (or will be if proposed) from an intersecting county road. State that no existing access is present or that no new access is proposed, if applicable. There is an existing agricultural access located on WCR 53 approximately 2,970 feet north of WCR 74, permit no. AP 19-00149. A new access permit to change the use to commercial is requested to be a Condition of Approval to the USR. Page 9 of 9 2. Describe any anticipated change(s) to an existing access, if applicable. No additional access points are proposed. A new access permit for commercial use will be submitted upon USR conditional approval. 3. Describe in detail any existing or proposed access gate including its location. There is an existing access gate at the entrance of the subject property. No additional access gates are proposed. 4. Describe the location of all existing accesses on adjacent parcels and on parcels located on the opposite side of the road. Include the approximate distance each access is from an intersecting county road. WCR 53 is a local gravel road maintained by Weld County. On the west side of WCR 53, the adjacent parcel located north of the subject property has an existing agricultural and oil and gas access approximately 3,750 feet north of WCR 74, and the adjacent parcel to the south of the subject property has an existing residential access approximately 2,640 feet north of WCR 74. On the east side of WCR 53, there is an existing residential and agricultural access located approximately 3,500 feet north of WCR 74. 5. Describe any difficulties seeing oncoming traffic from an existing access and any anticipated difficulties seeing oncoming traffic from a proposed access. As WCR 53 is a relatively flat and straight roadway in front of the entrance, and there are no significant visual obstructions in the sight triangles, no difficulties seeing oncoming traffic from the existing access are anticipated. 6. Describe any horizontal curve (using terms like mid curve, sharp curve, reverse curve, etc.) in the vicinity of an existing or proposed access. WCR 53 is a relatively flat and straight roadway in front of the entry and there are no significant horizontal curves in the vicinity of the existing approved access. 7. Describe the topography (using terms like flat, slight hills, steep hills, etc.) of the road in the vicinity of an existing or proposed access. WCR 53 is a relatively flat and straight roadway in front of the entry.

A vicinity map is shown in Appendix A. 2. Property Description The site currently contains a 2,280 square foot (sf) manufactured structure, 8,500 sf commercial shop, 8,700 sf greenhouse, 3,800 sf equipment building, one 300 sf storage shed, one 600 sf utility building, and a detention pond surrounded by agricultural lands. There will be no changes to the existing project site with the change in land usage. The building footprints are less than the H2S2 drainage report had accounted for. There are predominantly two soil types on site. The soils consist of mainly Shingle loam and a smaller portion of Renohill clay loam with zero to three percent slope. The majority of the soil is well drained, hydrologic soil group D (see USDA-NRCS soil report in Appendix B). There are no major open channels within the proposed property. Mason Reservoir is directly east of the project site's boundary. 9/14/2023 Drainage Narrative Page 5 of 9 ENGINEERING, PLANNING, CONSULTING & REAL ESTATE HQ & Mailing: 3050 67th Avenue, Suite 200, Greeley, CO 80634 I 970-535-9318 office I 970-535-9854 fax Idaho: 213 Canyon Crest Drive, Suite 100, Twin Falls, ID 83301 I 208-595-5301 www.agpros.com ECO Services Historic Drainage 1. Overall Basin Description The site has a generally flat topography with slopes from zero to three percent. A topographic map was downloaded from the United States Geological Survey (USGS) website and is provided in Appendix C. Historically, there have been no previous drainage issues with the property. A Federal Emergency Management Administration (FEMA) map of the project area is included in Appendix D. The property is located on panel 08123C1275E and is outside the floodplain boundaries. 2. Drainage Patterns Through Property The site is in an unincorporated part of Weld County northeast of the unincorporated townsite Zita Town known as Galeton. The property is surrounded by agricultural zoned land. A Master Plan for the site area is not currently available. The site is generally flat surface and appears to slope west. 3. Off -site Drainage Flow Patterns Offsite flows from the north appear to flow to the west away from the site. Offsite flows from the south appear to flow to the west away from the site. Offsite flows from the east appear to flow directly east and are intercepted by WCR 53 away from the site. Offsite flows from the west appear to flow to the west away from the site. Therefore, an increase in runoff is not expected. 9/14/2023 Drainage Narrative Page 6 of 9 ENGINEERING, PLANNING, CONSULTING & REAL ESTATE HQ & Mailing: 3050 67th Avenue, Suite 200, Greeley, CO 80634 I 970-535-9318 office I 970-535-9854 fax Idaho: 213 Canyon Crest Drive, Suite 100, Twin Falls, ID 83301 I 208-595-5301 www.agpros.com ECO Services Drainage Design Criteria 1. Development Criteria The proposed calculation was determined using the criteria set forth in the Urban Drainage and Flood Control District (UDFCD) Volumes 1, 2 and 3 and the Weld County Engineering and Construction Guidelines (WCECG) manual. 2. Hydrological Criteria From NOAA Atlas 14 Eaton, CO precipitation station, the estimated rainfall from the 10 - year, 1 -hour precipitation is 1.43 inches and the 100 -year, 1 -hour precipitation is 2.68 inches (see NOAA Atlas 14 Precipitation Data in Appendix E). Percentage of imperviousness was determined using the recommended values from UDFCD Table 6-3. The overall percentage of imperviousness for the proposed site was determined to be approximately 30 percent (see Percentage of Imperviousness Calculation in Appendix F). The 2019 Drainage Report the proposed percentage of imperviousness was 34 percent (see H2S2, LLC Final Drainage Report 6/21/2019 in Appendix G). The current percentage of imperviousness is lower than the provided Drainage Report indicating there will be a decrease in the projected runoff and peak flowrate of the original H2S2 Final Drainage Report. Therefore, the existing detention pond is sufficient. 9/14/2023 Drainage Narrative Page 7 of 9 ENGINEERING, PLANNING, CONSULTING & REAL ESTATE HQ & Mailing: 3050 67th Avenue, Suite 200, Greeley, CO 80634 I 970-535-9318 office I 970-535-9854 fax Idaho: 213 Canyon Crest Drive, Suite 100, Twin Falls, ID 83301 I 208-595-5301 www.agpros.com ECO Services Conclusions This drainage narrative is consistent with the Weld County Storm Drainage Criteria and the UDFCD Criteria Manual. An increased risk of damage from storm runoff is not expected as the percentage of imperviousness of the site is less than the percentage imperviousness the detention pond was designed to in the H2S2 Drainage Report. As there are no changes proposed to the imperviousness of the site that could cause a need to increase the size of the existing detention pond, the Use by Special Review is applicable for an exception to additional stormwater detention per Article XI, Storm Drainage Criteria, Section 8-11-40 Drainage Policy. 9/14/2023 Drainage Narrative Page 8 of 9 ENGINEERING, PLANNING, CONSULTING & REAL ESTATE HQ & Mailing: 3050 67th Avenue, Suite 200, Greeley, CO 80634 I 970-535-9318 office I 970-535-9854 fax Idaho: 213 Canyon Crest Drive, Suite 100, Twin Falls, ID 83301 I 208-595-5301 www.agpros.com ECO Services List of References Federal Emergency Management Agency.

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.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it 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, 11 Custom Soil Resource Report 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 56 Renohill clay loam, 0 to 3 percent slopes Map Unit Setting National map unit symbol: 3635 Elevation: 4,850 to 5,200 feet Mean annual precipitation: 11 to 16 inches Mean annual air temperature: 46 to 48 degrees F Frost -free period: 100 to 160 days Farmland classification: Farmland of statewide importance Map Unit Composition Renohill and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

Greeley CO 80634 * 970-535-9318 * IAINW.a2Dr0S.COM H2S2. LLC Introduction 1. Location The proposed site is located in part of the South 'A of the Northeast 'A of Section 32, Township 7N, Range 64W of the 6th PM. This site is located east of Highway 85 and east of the Town of Eaton, CO. The properties surrounding the site are primarily undeveloped, agricultural farm land and residential land. The property is partially bordered on the east side by Weld County Road (WCR) 53. The nearest road to the west is WCR 51, to the north is WCR 76 and to the south is WCR 74. No other major road ways are located within or adjacent to the property (see vicinity map in Appendix A). 2. Description of Property The proposed site comprised of two parcels totaling approximately 9.8 acres. The site is currently a non -urbanizing, agricultural property with an existing residence, greenhouse, and two outbuildings. There is an existing dirt road and concrete storage pad. The remainder of the site is vacant vegetative covered land. There are two types of soil: Renohill clay loam (0% to 3% slopes) and Shingle loam (1% to 3% slopes). The majority of the soil is well drained, hydrologic soil group D (see USDA -MRCS soil report in Appendix A). Bruce and Carol Imming are the owners of the property upstream and to the east of the proposed site. Tyler Dyer is the owner of the adjacent property to the north and west of the proposed site. Cecil Livestock and Land, LLC is the owner of the property partially adjacent to and south of the proposed site. John and Eileen Connell are the owners of the property partially adjacent to and south of the proposed site. No other properties are adjacent to the site. There are no major open channels within or adjacent to the proposed property. The applicant is proposing a hemp processing facility with a proposed 7,000 square foot storage building,a 15,000 square foot gravel parking lot, 3 grain bins on a concrete slab, 15,000 square foot agriculture exempt building and cargo containers. The portion of the two parcels that will be used for the hemp processing facility is 6.56 acres. 6/21/2019 Final Drainage Report Page 5 of 13 AGPROfessionals, 3050 67th Avenue, Greeley CO 80634 * 970-535-9318 * ainipros.cnhii 142S2. L[K rainage Basin and Sub -Basins 1. Major Basin Description The proposed site is non -urbanizing and is located in rural Weld County. A Master Plan for the site area is not currently available. The proposed site was considered as one major drainage basin for this report. Historically, the basin drainage flows towards the west-southwest into Willow Creek. Willow Creek flows into the South Platte River. The site is mostly west sloping and has a generally flat topography with slopes from zero to three percent predominately towards the western side of the property. Contours of the project location and the surrounding properties are shown on the United States Geological Survey (USGS) topographic map in Appendix A. A Federal Emergency Management Administration (FEMA) map of the project area is included in Appendix A. The property is located on panel 08123C1275E and is not currently located within a 100 -year floodplain. Potential offsite flows from the north, west and south should continue to flow west, away from the site. Offsite flows from the east should primarily be intercepted by WCR 53. Offsite flows from the residential lot to the east flow towards the proposed site but will be intercepted by the gravel entrance road. The flows will be directed south and continue to flow southwest around the site. Therefore, an increase in runoff is not expected. 2. Sub -Basin Description The site was evaluated with three subbasins labeled Subbasin A, B, and C, as well as one offsite Subbasin labeled OS -1. Stormwater runoff from Subbasins A, B and C will be directed to a proposed detention pond west of the proposed building. Subbasin A has a swale directing flow into the detention pond. The swale is labeled Proposed Swale A. Subbasin B also has a swale directing flow into the detention pond. The swale is labeled Proposed Swale B. Stormwater runoff from Subbasin OS -1 will continue to flow south and west, away from the site. 6/21/2019 Final Drainage Report Page 6 of 13 AGPROfessionals, 3050 67`t' Avenue, Greeley CO 80634 * 970-535-9318 * www.aepros.croun F12S2, L.C Drainage Design criteria 1. Development Criteria The proposed site runoff was evaluated using the criteria set forth in the UDFCD Criteria Manual Volumes 1, 2 and 3 and the WCECG manual. 2. Hydrological Criteria From the NOAA Atlas 14 Eaton, CO precipitation station, the estimated rainfall from the 10 -year, 1 -hour precipitation is 1.43 inches and the 100 -year, 1 -hour precipitation is 2.68 inches (see NOAA Atlas 14 Rainfall Maps in Appendix A). These values were used for runoff calculations and to estimate the required detention volume. Percentage of imperviousness was determined using the recommended values from UDFCD Table 6-3. A percentage of imperviousness of two percent was used for the historic site. The overall percentage of imperviousness for the proposed site was estimated to be 34 percent. The percentage of imperviousness for Subbasin A is approximately 24 percent, for Subbasin B is approximately 27 percent, and for Subbasin C is approximately 73 percent (see percentage of imperviousness calculations in Appendix A). Using the percentage of imperviousness, the design storms and UDFCD Detention basin Volume Estimating spreadsheet the historic and proposed peak runoff flowrates were estimated for the basins (see Table 1 and Overall Basin Peak Runoff Calculations in Appendix A). Peak runoff flowrates were also calculated for each subbasin with the rational method using the time of concentration, runoff coefficients, and the precipitation depths (see Subbasin Peak Runoff Calculations in Appendix A). Table 1: Peak Runoff Flowrates 100 Flowrate Year Peak (cfs) Peak Runoff 10 Flowrate Year Peak (cfs) Historic 3.81 14.02 Proposed 8.85 24.25 cfs = cubic feet per second 3. Hydraulic Criteria The 10 -year historic release rate was determined using the area of the proposed site and an estimated two percent historic imperviousness (see 10 -Year Historic Release Rate calculation in Appendix B). The detention pond volume required was calculated to be 0.67 acre-feet and the allowed release rate was calculated to be 3.81 cubic feet per second. The required volume was calculated using the Modified FAA method from the UDFCD Detention Basin Volume Estimating Workbook (see UDFCD Detention Volume calculation in Appendix B). The proposed detention pond will have a capacity greater than the required 0.67 acre-feet at the 100 -year water surface elevation with an additional 1 feet of freeboard (see Table 2 and UDFCD Stage Storage in Appendix B). 6/21/2019 Final Drainage Report Page 7 of 13 AGPROfessionals, 3050 67`'' Avenue, Greeley CO 80634 * 970-535-9318 * www:a rostconi H2s2, LLC Table 2: Stage Lora c Surma!

The WQCV is included within the detention volume for the 100 -year storm. A restrictor plate is proposed to control the flowrate through the outlet culvert (see UDFCD WQCV and UDFCD Restrictor Plate calculations in Appendix B). A single stage outlet structure is proposed with a rectangular opening and a 12 -inch reinforced concrete pipe (RCP) culvert (see UDFCD Outlet Structure and UDFCD Outlet Culvert in Appendix B). A spillway is proposed that is designed to release the 100 -year peak flowrate. The spillway crest will be at or above the invert of the freeboard elevation and the depth of the flow should be less than six inches (see UDFCD Spillway in Appendix B). Grass lined swales are proposed on the site to convey stormwater runoff towards the detention pond. The drainage channels were sized using the 100 -year, 1 -hour design storm peak flowrate per the WCECG. A Manning's n of 0.035 was used in calculations for a grass lined channel per the WCECG. The channels have 3:1 side slopes and have greater than one foot of freeboard for the 100 -year, 1 -hour storm event. The Froude numbers for the channels will be less than the maximum of 0.8 from WCECG. Calculations for the channel capacities were estimated using the NRCS Hydraulic Formula Software and are included in Appendix B. A culvert is proposed to convey stormwater for the Outlet (see Table 3). The culvert was sized to convey the historical release rate. A Manning's n of 0.013 was used in calculations for a concrete pipe per the WCECG. A slope of 0.5% was used in the design for the Outlet Culvert. Swale A and Swale B will be open channel flow into a Rock Chute Rip Rap design. The Rock Chute Rip Rap design was estimated using the NRCS Rock Chute Design. Spreadsheet. Calculations for the culvert capacity and rip rap sizing are included in Appendix B. Drainage Facility Design 1. General Concept A detention pond is proposed in the southwestern corner of the site. Runoff from Subbasin A should generally sheet flow towards Swale A. Swale A carries the flow west to the detention pond. Runoff from Subbasin B should generally sheet flow towards Swale B. Swale B carries the flow west to the detention pond. Subbasin C sheet flows directly to the pond. The pond is designed to detain the 100 -year storm event and release at the 10 -year historic rate. The site should not significantly alter the historic drainage 6/21/2019 Final Drainage Report Page 8 of 13 AGPROfessionals, 3050 67th Avenue, Greeley CO 80634 * 970-535-9318 * oww.agpros.com 1--12S2, LLC pattern. A historic drainage plan, drainage and erosion control plan, and drainage and erosion control details are provided in Appendix C. 2. Specific Details Maintenance access is provided on the northeast corner of the pond. A. Scheduled Maintenance of Proposed Facilities Scheduled maintenance will occur during daylight, weekday hours. Routine maintenance will include but should not be limited to the following: • Mowing of the bank slopes and area around the pond on a monthly basis during the growing season and as needed during the cooler months. • The outfall structure from the pond and other areas will be inspected monthly for debris which could inhibit the proper flow of discharge. Any debris will be removed immediately and disposed of or placed in a location to prevent future maintenance and to not cause impact up or downstream of the structure. • Trash will be removed from around the pond to prevent it entering the pond. Generally, the site should be kept free of loose trash which could be carried off site by wind or rain. • Inspect the pond and outfall structure for non -routine maintenance need. B. Periodic or Non -Scheduled Maintenance of Proposed Facility Periodic or non-scheduled maintenance includes routine inspection of the pond area and discharge/outfall structures to identify needed repairs and non -routine maintenance. These items may include but should not be limited to the following: • Pond area and outfall structure should be inspected after significant storm events. • Re -growth of trees on or around the pond bank. These should be cut and removed from the pond area. • Sediment from the site may accumulate in the pond bottom and reduce the pond to below design volume requirements. The pond should be excavated if the pond bottom elevation reached a level that allows excessive aquatic growth or reduces the pond efficiency such that the sediments are passing the discharge structure and release off site. 6/21/2019 Final Drainage Report Page 9 of 13 AGPROfessionals, 3050 67`'' Avenue, Greeley CO 80634 * 970-535-9318 * wwwwvw_arpros.com I I2S2. LLC Stabilization or re -grading of side slopes may be required periodically or after excessive rain events. Any disturbance of slopes should be reseeded or may require installation of erosion control materials until seeding can reestablish adequate grasses to prevent future erosion. • Any other maintenance or repairs which would minimize other maintenance to the pond or outfall structure. If the pond is significantly impaired such that the pond is incapable of properly functioning to meet the Weld County stormwater discharge requirements, the owner should assess the corrective action needed and have the pond restored by properly trained personnel. 6/21/2019 Final Drainage Report Page 10 of 13 AGPROfessionals, 3050 67`1i Avenue, Greeley CO 80634 * 970-535-9318 * \44 .i1'?11 itl.S.C.{rill H2S2, LLC Conclusions 1. Compliance with Weld County Code The drainage design of the H2S2, LLC USR is consistent with the Weld County Engineering and Construction Guidelines and the Weld County Code. No variances are needed with the current design with a detention pond to control and treat runoff prior to discharging. 2. Drainage Concept Historical flow patterns and run-off amounts should be maintained in such a manner that should reasonably preserve the natural character of the area and prevent property damage of the type generally attributed to run-off rate and velocity increases, diversions, concentration and/or unplanned ponding of storm run-off for the 100 -year storm event. The drainage design included in this report should be effective in controlling damage from the design storm runoff by detaining the 100 -year, 1 -hour storm event and releasing at the 10 -year historic rate. No irrigation companies or property owners should be affected by the proposed development. 6/21/2019 Final Drainage Report Page 11 of 13 AGPROfessionals, 3050 67t Avenue, Greeley CO 80634 * 970-535-9318 * www.agpros coi H2S2, L1,C List of References Federal Emergency Management Agency.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/ portal/nres/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www. n res. usda .gov/wps/portal/n res/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 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.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it 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, 11 Custom Soil Resource Report 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 56 Renohill clay loam, 0 to 3 percent slopes Map Unit Setting National map unit symbol: 3635 Elevation: 4,850 to 5,200 feet Mean annual precipitation: 11 to 16 inches Mean annual air temperature: 46 to 48 degrees F Frost -free period: 100 to 160 days Farmland classification: Farmland of statewide importance Map Unit Composition Renohill and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

Greeley CO 80634 * 970-535-9318 * IAINW.a2Dr0S.COM H2S2. LLC Introduction 1. Location The proposed site is located in part of the South 'A of the Northeast 'A of Section 32, Township 7N, Range 64W of the 6th PM. This site is located east of Highway 85 and east of the Town of Eaton, CO. The properties surrounding the site are primarily undeveloped, agricultural farm land and residential land. The property is partially bordered on the east side by Weld County Road (WCR) 53. The nearest road to the west is WCR 51, to the north is WCR 76 and to the south is WCR 74. No other major road ways are located within or adjacent to the property (see vicinity map in Appendix A). 2. Description of Property The proposed site comprised of two parcels totaling approximately 9.8 acres. The site is currently a non -urbanizing, agricultural property with an existing residence, greenhouse, and two outbuildings. There is an existing dirt road and concrete storage pad. The remainder of the site is vacant vegetative covered land. There are two types of soil: Renohill clay loam (0% to 3% slopes) and Shingle loam (1% to 3% slopes). The majority of the soil is well drained, hydrologic soil group D (see USDA -MRCS soil report in Appendix A). Bruce and Carol Imming are the owners of the property upstream and to the east of the proposed site. Tyler Dyer is the owner of the adjacent property to the north and west of the proposed site. Cecil Livestock and Land, LLC is the owner of the property partially adjacent to and south of the proposed site. John and Eileen Connell are the owners of the property partially adjacent to and south of the proposed site. No other properties are adjacent to the site. There are no major open channels within or adjacent to the proposed property. The applicant is proposing a hemp processing facility with a proposed 7,000 square foot storage building,a 15,000 square foot gravel parking lot, 3 grain bins on a concrete slab, 15,000 square foot agriculture exempt building and cargo containers. The portion of the two parcels that will be used for the hemp processing facility is 6.56 acres. 6/21/2019 Final Drainage Report Page 5 of 13 AGPROfessionals, 3050 67th Avenue, Greeley CO 80634 * 970-535-9318 * ainipros.cnhii 142S2. L[K rainage Basin and Sub -Basins 1. Major Basin Description The proposed site is non -urbanizing and is located in rural Weld County. A Master Plan for the site area is not currently available. The proposed site was considered as one major drainage basin for this report. Historically, the basin drainage flows towards the west-southwest into Willow Creek. Willow Creek flows into the South Platte River. The site is mostly west sloping and has a generally flat topography with slopes from zero to three percent predominately towards the western side of the property. Contours of the project location and the surrounding properties are shown on the United States Geological Survey (USGS) topographic map in Appendix A. A Federal Emergency Management Administration (FEMA) map of the project area is included in Appendix A. The property is located on panel 08123C1275E and is not currently located within a 100 -year floodplain. Potential offsite flows from the north, west and south should continue to flow west, away from the site. Offsite flows from the east should primarily be intercepted by WCR 53. Offsite flows from the residential lot to the east flow towards the proposed site but will be intercepted by the gravel entrance road. The flows will be directed south and continue to flow southwest around the site. Therefore, an increase in runoff is not expected. 2. Sub -Basin Description The site was evaluated with three subbasins labeled Subbasin A, B, and C, as well as one offsite Subbasin labeled OS -1. Stormwater runoff from Subbasins A, B and C will be directed to a proposed detention pond west of the proposed building. Subbasin A has a swale directing flow into the detention pond. The swale is labeled Proposed Swale A. Subbasin B also has a swale directing flow into the detention pond. The swale is labeled Proposed Swale B. Stormwater runoff from Subbasin OS -1 will continue to flow south and west, away from the site. 6/21/2019 Final Drainage Report Page 6 of 13 AGPROfessionals, 3050 67`t' Avenue, Greeley CO 80634 * 970-535-9318 * www.aepros.croun F12S2, L.C Drainage Design criteria 1. Development Criteria The proposed site runoff was evaluated using the criteria set forth in the UDFCD Criteria Manual Volumes 1, 2 and 3 and the WCECG manual. 2. Hydrological Criteria From the NOAA Atlas 14 Eaton, CO precipitation station, the estimated rainfall from the 10 -year, 1 -hour precipitation is 1.43 inches and the 100 -year, 1 -hour precipitation is 2.68 inches (see NOAA Atlas 14 Rainfall Maps in Appendix A). These values were used for runoff calculations and to estimate the required detention volume. Percentage of imperviousness was determined using the recommended values from UDFCD Table 6-3. A percentage of imperviousness of two percent was used for the historic site. The overall percentage of imperviousness for the proposed site was estimated to be 34 percent. The percentage of imperviousness for Subbasin A is approximately 24 percent, for Subbasin B is approximately 27 percent, and for Subbasin C is approximately 73 percent (see percentage of imperviousness calculations in Appendix A). Using the percentage of imperviousness, the design storms and UDFCD Detention basin Volume Estimating spreadsheet the historic and proposed peak runoff flowrates were estimated for the basins (see Table 1 and Overall Basin Peak Runoff Calculations in Appendix A). Peak runoff flowrates were also calculated for each subbasin with the rational method using the time of concentration, runoff coefficients, and the precipitation depths (see Subbasin Peak Runoff Calculations in Appendix A). Table 1: Peak Runoff Flowrates 100 Flowrate Year Peak (cfs) Peak Runoff 10 Flowrate Year Peak (cfs) Historic 3.81 14.02 Proposed 8.85 24.25 cfs = cubic feet per second 3. Hydraulic Criteria The 10 -year historic release rate was determined using the area of the proposed site and an estimated two percent historic imperviousness (see 10 -Year Historic Release Rate calculation in Appendix B). The detention pond volume required was calculated to be 0.67 acre-feet and the allowed release rate was calculated to be 3.81 cubic feet per second. The required volume was calculated using the Modified FAA method from the UDFCD Detention Basin Volume Estimating Workbook (see UDFCD Detention Volume calculation in Appendix B). The proposed detention pond will have a capacity greater than the required 0.67 acre-feet at the 100 -year water surface elevation with an additional 1 feet of freeboard (see Table 2 and UDFCD Stage Storage in Appendix B). 6/21/2019 Final Drainage Report Page 7 of 13 AGPROfessionals, 3050 67`'' Avenue, Greeley CO 80634 * 970-535-9318 * www:a rostconi H2s2, LLC Table 2: Stage Lora c Surma!

The WQCV is included within the detention volume for the 100 -year storm. A restrictor plate is proposed to control the flowrate through the outlet culvert (see UDFCD WQCV and UDFCD Restrictor Plate calculations in Appendix B). A single stage outlet structure is proposed with a rectangular opening and a 12 -inch reinforced concrete pipe (RCP) culvert (see UDFCD Outlet Structure and UDFCD Outlet Culvert in Appendix B). A spillway is proposed that is designed to release the 100 -year peak flowrate. The spillway crest will be at or above the invert of the freeboard elevation and the depth of the flow should be less than six inches (see UDFCD Spillway in Appendix B). Grass lined swales are proposed on the site to convey stormwater runoff towards the detention pond. The drainage channels were sized using the 100 -year, 1 -hour design storm peak flowrate per the WCECG. A Manning's n of 0.035 was used in calculations for a grass lined channel per the WCECG. The channels have 3:1 side slopes and have greater than one foot of freeboard for the 100 -year, 1 -hour storm event. The Froude numbers for the channels will be less than the maximum of 0.8 from WCECG. Calculations for the channel capacities were estimated using the NRCS Hydraulic Formula Software and are included in Appendix B. A culvert is proposed to convey stormwater for the Outlet (see Table 3). The culvert was sized to convey the historical release rate. A Manning's n of 0.013 was used in calculations for a concrete pipe per the WCECG. A slope of 0.5% was used in the design for the Outlet Culvert. Swale A and Swale B will be open channel flow into a Rock Chute Rip Rap design. The Rock Chute Rip Rap design was estimated using the NRCS Rock Chute Design. Spreadsheet. Calculations for the culvert capacity and rip rap sizing are included in Appendix B. Drainage Facility Design 1. General Concept A detention pond is proposed in the southwestern corner of the site. Runoff from Subbasin A should generally sheet flow towards Swale A. Swale A carries the flow west to the detention pond. Runoff from Subbasin B should generally sheet flow towards Swale B. Swale B carries the flow west to the detention pond. Subbasin C sheet flows directly to the pond. The pond is designed to detain the 100 -year storm event and release at the 10 -year historic rate. The site should not significantly alter the historic drainage 6/21/2019 Final Drainage Report Page 8 of 13 AGPROfessionals, 3050 67th Avenue, Greeley CO 80634 * 970-535-9318 * oww.agpros.com 1--12S2, LLC pattern. A historic drainage plan, drainage and erosion control plan, and drainage and erosion control details are provided in Appendix C. 2. Specific Details Maintenance access is provided on the northeast corner of the pond. A. Scheduled Maintenance of Proposed Facilities Scheduled maintenance will occur during daylight, weekday hours. Routine maintenance will include but should not be limited to the following: • Mowing of the bank slopes and area around the pond on a monthly basis during the growing season and as needed during the cooler months. • The outfall structure from the pond and other areas will be inspected monthly for debris which could inhibit the proper flow of discharge. Any debris will be removed immediately and disposed of or placed in a location to prevent future maintenance and to not cause impact up or downstream of the structure. • Trash will be removed from around the pond to prevent it entering the pond. Generally, the site should be kept free of loose trash which could be carried off site by wind or rain. • Inspect the pond and outfall structure for non -routine maintenance need. B. Periodic or Non -Scheduled Maintenance of Proposed Facility Periodic or non-scheduled maintenance includes routine inspection of the pond area and discharge/outfall structures to identify needed repairs and non -routine maintenance. These items may include but should not be limited to the following: • Pond area and outfall structure should be inspected after significant storm events. • Re -growth of trees on or around the pond bank. These should be cut and removed from the pond area. • Sediment from the site may accumulate in the pond bottom and reduce the pond to below design volume requirements. The pond should be excavated if the pond bottom elevation reached a level that allows excessive aquatic growth or reduces the pond efficiency such that the sediments are passing the discharge structure and release off site. 6/21/2019 Final Drainage Report Page 9 of 13 AGPROfessionals, 3050 67`'' Avenue, Greeley CO 80634 * 970-535-9318 * wwwwvw_arpros.com I I2S2. LLC Stabilization or re -grading of side slopes may be required periodically or after excessive rain events. Any disturbance of slopes should be reseeded or may require installation of erosion control materials until seeding can reestablish adequate grasses to prevent future erosion. • Any other maintenance or repairs which would minimize other maintenance to the pond or outfall structure. If the pond is significantly impaired such that the pond is incapable of properly functioning to meet the Weld County stormwater discharge requirements, the owner should assess the corrective action needed and have the pond restored by properly trained personnel. 6/21/2019 Final Drainage Report Page 10 of 13 AGPROfessionals, 3050 67`1i Avenue, Greeley CO 80634 * 970-535-9318 * \44 .i1'?11 itl.S.C.{rill H2S2, LLC Conclusions 1. Compliance with Weld County Code The drainage design of the H2S2, LLC USR is consistent with the Weld County Engineering and Construction Guidelines and the Weld County Code. No variances are needed with the current design with a detention pond to control and treat runoff prior to discharging. 2. Drainage Concept Historical flow patterns and run-off amounts should be maintained in such a manner that should reasonably preserve the natural character of the area and prevent property damage of the type generally attributed to run-off rate and velocity increases, diversions, concentration and/or unplanned ponding of storm run-off for the 100 -year storm event. The drainage design included in this report should be effective in controlling damage from the design storm runoff by detaining the 100 -year, 1 -hour storm event and releasing at the 10 -year historic rate. No irrigation companies or property owners should be affected by the proposed development. 6/21/2019 Final Drainage Report Page 11 of 13 AGPROfessionals, 3050 67t Avenue, Greeley CO 80634 * 970-535-9318 * www.agpros coi H2S2, L1,C List of References Federal Emergency Management Agency.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/ portal/nres/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www. n res. usda .gov/wps/portal/n res/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 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 (AOl ) Area of Interest (AOl) Soils O Soil Map Unit Polygons Soil Map Unit Lines Soil Map Unit Points Special Point Features Blowout Borrow Pit Clay Spot Closed Depression Gravel Pit Gravelly Spot Landfill Lava Flow Marsh or swamp Mine or Quarry Miscellaneous Water Perennial Water Rock Outcrop Saline Spot Sandy Spot Severely Eroded Spot Sinkhole Slide or Slip Sadie Spot -04 0 it ftsfa 0 0 ?t4 0 0 Spoil Area Stony Spot Very Stony Spot Wet Spot Other Special Line Features Water Features Streams and Canals Transportation Rails Interstate Highways US Routes Major Roads Local Roads Background Aerial Photography MAP INFORMATION The soil surveys that comprise your AOI were mapped at 1:24,000.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it 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, 11 Custom Soil Resource Report 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 56 Renohill clay loam, 0 to 3 percent slopes Map Unit Setting National map unit symbol: 3635 Elevation: 4,850 to 5,200 feet Mean annual precipitation: 11 to 16 inches Mean annual air temperature: 46 to 48 degrees F Frost -free period: 100 to 160 days Farmland classification: Farmland of statewide importance Map Unit Composition Renohill and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

The subject property is currently permitted as a hemp processing facility but is not currently operating. It is expected that the operation will have 15-20 full-time employees. The expected work hours will vary based on job type. Parking and equipment storage will occur 24 hours per day, 7 days per week. The primary hours for outgoing and incoming vehicles and equipment will be Monday through Sunday, 4:00 A.M. to 6:00 P.M. Other uses in the surrounding area include dairy operations, Ag Service Establishments, water tank, group home, contractor's shop, a church, and various agricultural and rural residential uses. ECO Services will use the methods described below to minimize potential nuisances and waste produced as a result of the proposed uses. Noise The property owner or operator will attempt to minimize noise generated during operation and maintain compliance with Weld County Noise Requirements. The facility will adhere to the maximum permissible noise levels allowed in the Agricultural Zone District. Operations will primarily occur within the existing shop buildings providing an additional sound buffer. Light Outdoor lighting will be building -mounted. Sources of light will be shielded so that light rays will not shine directly onto adjacent properties where such would cause a nuisance or interfere with the use on the adjacent properties. Neither the direct, nor reflected light from any light source will create a traffic hazard to operators of motor vehicles on public or private streets. No colored light will be used which may be confused with, or construed as, traffic control devices.

ECO Services attempts to limit the amount of waste generated from the fabrication of secondary containment liners. Larger scrap pieces will be saved and used in repairs as needed. For off -site operations, the fabrication and repair of liners on site may generate a minor amount of waste materials. If trash dumpsters are not available at the job locations, the material will be brought back to the site and disposed of. For all on -site operations, trash will be collected in a covered, confined trash dumpster and removed as needed by a trash removal company. There is no sanitary sewer service to, or within four hundred feet of, the subject property. The existing septic system on site, SP -0701062, is expected to be adequate for the 5-7 employees who will be on site regularly. One 500 -gallon fuel tank is proposed to be located on -site for business needs. It will include both primary and secondary containment. Dust Abatement The operation is not expected to generate disproportionate amounts of fugitive dust. Lot surfaces are primarily native grass and improved gravel surfaces in roadways, parking, and operations areas. Parking is internal to the site. The subject property is accessed along the east of the parcel from the existing gravel drive located on Weld County Road (WCR) 53 approximately one half of a mile north of WCR 74. WCR 53 is a local gravel road maintained by Weld County. Vehicles will not gain significant speed on -site before the access road intersects with WCR 53 due to the distance from the operations area to WCR 53. Watering of surfaces will occur as necessary to suppress dust. AGPROfessionals DEVELOPERS OF AGRICULTURE Traffic Narrative Weld County USR Application Prepared for ECO Services, LLC AGPRCfessionals DEVELOPERS OF AGRICULTURE Traffic Narrative Prepared for ECO Services, LLC Introduction This Traffic Narrative is prepared for the ECO Services, LLC (ECO Services) Use by Special Review request for an oil and gas support and services business in the Agricultural Zone District, more specifically a secondary containment liner company. The subject property is described as Lot A of Recorded Exemption RECX 17-01861ocated in Part of the South Half of the Northeast Quarter of Section 32, Township 7 North, Range 64 West of the 6th P.M., Weld County, Colorado. The approximately 9.53 -acre property is located on Weld County Road (WCR) 53 approximately one half of a mile north of WCR 74. The purpose of this narrative is to document projected traffic generation relative to the existing street system. Off -site roadway warrants are not provided with this memorandum, nor are existing traffic counts documented. Existing Conditions and Roadway Network The subject property is accessed on the east part of the parcel from the existing gravel drive located on WCR 53 approximately one half of a mile north of WCR 74. WCR 53 is a gravel two-lane north -south street and is classified as a local roadway. WCR 74 is a paved east -west street and is classified as an arterial according to the 2045 Transportation Plan. All routes to and from the site will be on WCR 53. Proposed Development The site is an existing hemp processing facility, permitted under USR 19-0015. The current buildings will remain and be re -purposed for use by ECO Services. Due to the reduction in proposed employees for the operation, a reduction in the proposed traffic is expected from what was previously approved through USR 19-0015. The on -site operation will primarily be the fabrication and repair of secondary containment liners for use at oil and gas tank battery sites. The majority of Eco Services' operations will occur off - site at various oil and gas locations around the county. The commercial shop will primarily be used to store company equipment and vehicles. Vehicles that may be on -site include company ENGINEERING, PLANNING, CONSULTING & REAL ESTATE HQ & Mailing: 3050 67th Avenue, Suite 200, Greeley, CO 80634 1970-535-9318 office 1970-535-9854 fax Idaho: 213 Canyon Crest Drive, Suite 100, Twin Falls, ID 83301 1208-595-5301 www.agpros.com Page 2 of 3 trucks and employee passenger vehicles, trailers, and one semi -truck and trailer. The majority of the equipment is staged at the construction site and returned to the facility as needed. Trip Generation Parking and equipment storage will occur 24 hours per day, 7 days per week. The expected hours for outgoing and incoming vehicles and equipment will be Monday through Sunday, 4:00 A.M. to 6:00 P.M. The highest traffic volumes will be generated during the morning hours of 4:00 A.M. to 7:00 A.M. with the Peak Hour being 4:00 A.M. to 5:00 A.M., and in the evening between 4:00 P.M. to 6:00 P.M. with the Peak Hour being 4:00 P.M. to 5:00 P.M.
