As evidenced by the fact that Jay Stroh signed the lease agreement, we do not anticipate any problem with him signing the form once he is available; the challenge is simply tracking him down right now. Because we are providing the County with a copy of the lease agreement as proof that the Strohs are on board with this application (attached at the end of this packet), we would ask that you please proceed with processing this application and we will provide the County with a copy of this signed form as soon as we are able to get it.

Questions that do not pertain to this project are noted as "Not applicable" according to the Weld County document instructions. Planning Questions 1. Explain, in detail, the proposed use of the property. The Colt Station Liquid Capture Facility (Colt Facility) will be used to capture and stabilize drip condensate from unconditioned natural gas delivered to the site by pipelines. As unconditioned natural gas is gathered in pipelines, drip condensate accumulates in the low spots of the pipelines which are periodically cleared using pigs. Drip condensate contains both hydrocarbons and water which must be cleared to avoid excessive backpressure in the pipeline. Hydrocarbons (natural gas liquids or NGLs) stabilized to atmospheric conditions at the Colt Facility will be transported to market through a pipeline. Water separated from the drip condensate stream at the Colt Facility will be trucked offsite for disposal. The Colt Facility will receive unconditioned natural gas from the South Area Gas Pipeline (USR17-0034). Captured and stabilized natural gas will be offloaded to third parties close to this facility also using pipelines. The stabilized NGL will be transported via pipeline to a nearby existing crude oil sales pipeline. Should this existing pipeline not be available, the stabilized NGL will be transported by truck. On -site, flash gas will be recompressed with a vapor recovery compressor to be transported to the sales point(s) with some nominal amount of gas contained in the vapor space being combusted from the atmospheric tanks. A space for a laydown yard has also been planned on the site in case such a space is needed by Green River Dev Co in the future. 2. Explain how this proposal isconsistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. The proposed facility will be consistent with the intent of the Comprehensive Plan as follows: A. Policy 7.2.: Conversion of agricultural land to nonurban residential, commercial and industrial uses should be accommodated when the subject site is in an area that can support such development, and should attempt to be compatible with the region. The land that will be used for the Colt Facility is non -irrigated rangeland that is in a sparsely populated portion of the County where oil and gas development is a common land use. Green River DevCo will work with neighbors to minimize impacts and respond to compatibility concerns they may have. OG.Goal 1: Promote the reasonable and orderly exploration and development of oil and gas mineral resources; and OG.Goal 2: Ensure that the extraction of oil and gas resources conserves the land and minimizes the impact on surrounding land and the existing surrounding land use. The facility is located along the alignment of some natural gas pipelines permitted by Green River DevCo on a parcel of land that is being used by other oil and gas companies for oil and gas development purposes. The land being leased by Green River is in the middle of the parcel which is a benefit to surrounding landowners because it provides a larger buffer between the Colt Facility and the land owned by other people, some of which are residential properties. TETRA TECH 1 USR Questionnaire 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the zone district in which it is located. The property is in the Agricultural Zone District. According to the Weld County Code, oil and gas support and service facilities, as proposed on this application, are a Use by Special Review in the Agricultural Zoning District. 4. Describe what type of land uses surround the site. Explain how the proposed use is consistent and compatible with surrounding land uses. The Colt Facility will be located on an SUBX lot interior to a larger parcel of land that is currently non -irrigated agricultural land with some other oil and gas facilities. The parcel being leased and developed by Green River as the Colt Facility is almost 1 000 feet north of WCR 34%. To the south side of WCR 34% is the Milton Lake Estates Subdivision which contains several large residential lots. Green River will reach out to these neighbors to discuss the project and take steps to address compatibility concerns. Compatibility concerns will be minimized by the fact that the facility will generate a minimal amount of traffic. Light impacts will be minimized by having just one security light at the entrance to the facility and a few other key higher value locations within the facility minimize off -site light pollution. All other lights on the site are operational lights that will only be turned on if employees need to be on -site when it is dark; however, it is not anticipated that this will occur regularly. Noise impacts from the facility will be minimized by enclosing equipment within buildings and providing acoustical insulation. While the exact noise levels generated by the site are not known at this point in the facility design process, Green River can say that any noise generated by this facility will not exceed the 50 dB(A) when measured from any of the neighboring residential properties. 5. What are the hours and days of operation? (e.g. Monday thru Friday 8:00 a.m. to 5:00 p.m.) Equipment at the facility will operate 24 hours a day, 7 days a week, for 365 days a year; however, the facility is unmanned. Unless there is an emergency, employees will generally visit the site between the hours of 7:00 am to 5:00 pm. 6. List the number of full time and/or part time employees proposed to work at this site. The facility will be an unmanned facility. 7. If shift work is proposed include the number of employees per shift. The facility will be an unmanned facility. 8. List the number of people who will use this site. Include contractors, truck drivers, customers, volunteers, etc. Green River DevCo representatives may access the site temporarily to perform testing and maintenance tasks. It is anticipated that a maximum of 1 to 2 employees in pick-up trucks could stop by the site per day. 9. If this is a dairy, livestock confinement operation, kennel, etc., list the number and type of animals. Not Applicable 10. Describe the type of lot surface and the square footage of each type. (e.g. asphalt, gravel, landscaping, dirt, grass, buildings). The lot will be surfaced with a pea gravel cover for stabilization of the ground. Vegetation will not be re- established on much of the site due to brush fire potential. The roads and the laydown area will be surfaced with a compacted aggregate base course and have a total area of approximately 89,000 square feet (30% of lot area). The total area of equipment and building foundations is approximately 14,000 square feet (5% of lot area). The remainder of the site, approximately 196,000 square feet (65% of lot area) will be surfaced with a pea gravel cover for stabilization of the ground. 11. How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed? This is not a manned facility so no designated parking spaces are proposed. As employees visit the site, they will park near the equipment that they are at the site to service. TETRA TECH 2 USR Questionnaire 12. Explain the existing and proposed landscaping for the site. Existing vegetation at the site is native grasses. Due to the fire risk at the site, landscaping is not proposed. However, this should not be an issue because the Colt Facility is going to be on a SUBX lot that is in the center of a larger parcel and there will be about 1000' between the edge of the Facility and the nearest homes that are south of WCR 341A 13. Describe the type of fence proposed for the site (e.g. 6 -foot chain link with earth tone slats). A 6 -foot chain link security fence will surround the property. A detail of the fence is provided on sheet 3 of the USR map. 14. Describe the proposed screening for all parking and outdoor storage areas. If the site is located in a floodplain outdoor storage is restricted. A laydown yard is proposed on the lot. No screening is proposed because the site is about 1000' feet away from the nearest residential property. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. When the Colt Facility is no longer needed, the equipment will be removed from the property and the site will be reclaimed with native grassland vegetation. 16. Who will provide fire protection to the site? This is in the La Salle Fire Protection District. 17. List all proposed on -site and off -site improvements associated with the use (e.g. landscaping, fencing, buildings, drainage, turn lanes, etc.) and a timeline of when you will have each one of the improvements completed. Following approval of the USR, within 5-6 months the facility will be constructed. This will include the access road to and into the site; the equipment at the facility; the security fence around the facility, and all the required drainage improvements (channels, culverts and detention pond). TETRA TECH 3 USR Questionnaire Engineering Questions 1. Describe how many raundtripsldays are expected for each vehicle type: Passenger Cars/Pickups, Tandem Trucks, Semi-Truck/Trailer/RV (Roundtrip = 1 trip in and 1 trip out of site). When the site is operational, up to 2 pickup trucks are expected to stop by the site per day. In the situation that the pipeline is not available, up to 4 tanker trucks per day could be used to haul product from the site. When the laydown yard is being used, up to 4 semi -trucks could access the site per day. 2. Describe the expected travel routes for site traffic. Vehicles will travel on WCR 49 to WCR 341/2 to access the site. Vehicles will enter the site from an existing access point off WCR 34%. They will then travel north to the facility on a road that is in an access easement. 3. Describe the travel distribution along the routes (e.g. 50% of traffic will come from the north, 20% from the south, 30% from the east, etc.) It is anticipated that all the traffic will come and go from the site using WCR 49 and WCR 3414. 4. Describe the time of day that you expect the highest traffic volumes from above. It is anticipated that the highest traffic volumes to and from the site will be in the morning hours (7:00 AM - noon ) 5. Describe where the access to the site is planned. Access to the site is planned from an existing access point off Weld County Road 341/2 which is located approximately 1 of a mile west of WCR 49. 6.

Typical development of any site will introduce impervious elements to the basin. Impervious material within a basin will increase peak stormwater runoff compared with runoff from existing conditions. This report examines the undeveloped flow patterns of offsite and onsite drainage basins and the proposed stormwater facilities designed to mitigate the downstream impact of increased stormwater runoff The contents of this report are prepared, at a minimum, in accordance with Weld County Code and the Urban Storm Drainage Criteria Manual, Volumes 1. 2. and 3 for a Preliminary Drainage Report. 2.0 GENERAL LOCATION AND DESCRIPTION 2.1 Location The Colt Station site is located on parcel (No. 121312100004) located on the west side of Weld County Road (WCR 49, approximately one -quarter mile north of WCR 34.5 in Weld County, Colorado. More specifically, the site is in the northeast 114 quarter of Section 12, Township 3 North, Range 65 West of the 6th Principal Meridian, in Weld County. A vicinity map is provided in Appendix A-1. 2.2 Description of Property The Colt Station Liquid Capture Facility (Colt Station) will be used to capture and stabilize drip condensate from unconditioned natural gas delivered to the site by pipelines. As unconditioned natural gas is gathered in pipelines, drip condensate accumulates in the low spots of the pipelines which are periodically cleared using pigs. Drip condensate contains both hydrocarbons and water which must be cleared to avoid excessive backpressure in the pipeline. Hydrocarbons (natural gas liquids or NGLs) stabilized to atmospheric conditions at Colt Station will be transported to market through a pipeline. Water separated from the drip condensate stream at Colt Station will be trucked offsite for disposal. Colt Station will receive unconditioned natural gas from the South Area Gas Pipeline (USR17- 0034). Captured and stabilized natural gas will be transported off -site by the Colt to Crossroads pipeline (USR 17-0077). If the Colt to Crossroads pipeline is temporarily unavailable, the stabilized NGL will be transported by truck. On -site, flash gas will be recompressed with a vapor recovery compressor with some nominal amount of gas contained in the vapor space being combusted from the atmospheric tanks. A space for a laydown yard has also been planned on the site in case such a space is needed by Green River in the future. The site is currently undeveloped and is co -owned by Stroh Family Trust and OGG and 5, LLC. The proposed land use will be industrial. Existing topography within the parcel is comprised of mild slopes in a southeast direction. Vegetative cover is comprised of native grasses with no trees. Surrounding land uses include rural residential, agricultural and oil and gas related development. According to the Custom Soil Resource Report for Weld County, Colorado, Southern Part, the soils that make up the site include primarily valent sand and vona laomy sand, ranging in slope from approximately 0 to 9 percent. A detailed soil survey report is provided in Appendix B-2. Soil types within the project site are predominantly hydrologic soil group A. Preliminary Drainage Report 2 June 2018 Colt Liquid Receipts Facility O:\Projects\Lnngment435719\200-35719-18005\Does\Reports\Drainage Report\DrainageReport_C"olt.docx 3.0 DRAINAGE BASINS AND SUB -BASINS 3.1 Major Basin Description The proposed property is in rural Weld County and is surrounded by agricultural land and low density residential. Proposed development is in a Zone X, Area of Minimal Flood Hazard. The site is in Flood Insurance Rate Map (FIRM), Community Panel No. 08123 C 1975E, attached to this report as Appendix B -I. The site is located in a non -urbanizing area as defined in the Weld County Code. 3.2 Historic Drainage Patterns The project site is located within one historic drainage basin, which has been designated as Historic Basin A. Historic Basin A includes only the project site property. Offsite areas that drain to Point of Analysis (POA) A were not considered in the historic runoff calculations because they remain unchanged as a result of the project. Runoff within Historic Basin A flows across the site to the south and east. Runoff within this basin was analyzed using the Rational Method. The following table provides the peak flow rates for the historic drainage basin that drains to the location of the proposed detention pond. Table 1 Historic Drainage Basins Peak Flow Basin ID Peak Flow Acres 10 Year (cfs) Peak Flow 100 Year (cfs) A 6.86 0.09 3.05 3.3 Offsite Drainage Patterns Offsite drainage that drains to the proposed site is comprised of two basins designated as Offsite (OS) - 1A and OS -2A. Basin OS -1A is located on the west side of the project site and drains toward the project site and to the south and then east. Runoff from Basin OS -1A will be intercepted by an offsite channel and conveyed to the south and east, around the perimeter of the site, to its historic discharge location, POA A. Basin OS -2A is located to the north of the proposed site and drains south towards the site and ultimately to the east. Runoff from Basin OS -2A will be intercepted by a drainage channel and conveyed to the east, along the north side of the site, to its historicdischarge point, POA A. Peak flows for the 10 -year and 100 -year storm events for the offsite drainage basins are provided in the following table. Preliminary Drainage Report 3 June 2018 Colt Liquid Receipts Facility o:\Projects\Lnngment435719\200-35719-18005\Does\Reports\Drainage Report\DrainageReport_C"olt.docx Table 2 Offsite Drainage Basins Peak Flow Peak Peak Flow Corresponding Flow Acres 10 Year (cfs) 100 Year (cfs) POA Basin ID 0S -1A 6.72 0.12 2.63 A OS -1B 4.36 0.10 1.94 B The allowable release rate from site at POA A cannot exceed the 10 -year pre -project historic flow. The allowable release rate from the detention pond is the 10 -year historic flow from basin A. The total allowable release rate from the detention pond is 0.1 cfs. Drainage ditches and culverts along the perimeter of the site are designed to convey offsite flows around the development to prevent co -mingling with on -site drainage, and to maintain the historic drainage pattern. The offsite drainage plan is attached to this report as Appendix A-3. 4.0 DRAINAGE DESIGN CRITERIA This report is prepared in compliance with the Weld County Code and the Urban Storm Drainage Criteria Manual, Volumes 1, 2, and 3. Within the proposed development, the 100 -year storm is used as the major storm event when evaluating existing and proposed drainage facilities. The 100 -year storm is used because flooding from a storm of this magnitude could cause considerable damage to equipment if adequate stormwater controls were not sized for this magnitude of a storm. Previous drainage studies have not been found for this area. This is most likely a result of the site being in a rural environment. Runoff Calculations: Because all the drainage basins for this site are less than 160 acres, the Rational Method was used in stormwater runoff calculations.. Time of concentration calculations for individual basins were estimated using the methods detailed within Urban Storm Drainage Criteria Manual, Volume 1, Ch. 6. Rainfall Data: Site rainfall depth information was obtained from the National Oceanic and Atmospheric Administration (NOAA) Atlas 14, Volume 8, Version 2, Precipitation -Frequency Atlas of the United States (2013) as well as NOAA's Hydrometeorological Design Studies Center's Precipitation Frequency Data Server. Rainfall data is presented in Appendix B-3. Culvert Sizing: Culvert sizes were determined using Bentley CulvertMaster version 3. sofitware. Culvert sizing calculations are provided in Appendix C1. Drainage Channel Sizing: Drainage channels were sized for the 100 -year storm event using Manning's Equation. Detailed channel calculations are provided in Appendix C-2. Turf Reinforcement Mat (TRM) or Erosion Control Blanket (ECB) is recommended in all vegetated drainage channels. ROLLMAX VMax SC250 TRM, or approved equal, and North American Green RollMax S150 ECB, or approved equal, is recommended. Riprap will be placed at all culvert outfalls, and has been sized according to the Urban Drainage Flood Control District Manual, Volume 2. A drainage calculation summary describing drainage channel, culvert properties, and rip -rap calculations is provided in Appendix C-3. Preliminary Drainage Report 4 June 2018 Colt Liquid Receipts Facility O:\Projects\Lnngment435719\200-35719-18005\Does\Reports\Drainage Report\DrainageReport_C"olt.docx Detention Pond Sizing: The detention pond volume was determined using the UDFCD's Detention Design — UD-Detention v3.07 spreadsheet. The detention pond outlet was sized to allow the Water Quality Capture Volume (WQCV) to drain through an orifice plate. The orifice plate is designed to allow the stormwater in the detention pond to settle and drain slowly to improve water quality. 5.0 DRAINAGE FACILITY DESIGN 5.1 General Concept Onsite runoff will 3e detained in one detention pond onsite and discharged on the southeast side of the site towards POA A. The peak runoff for the historic condition was calculated for the area that drains to the detention pond (Detention Pond A) to determine the allowable release rate for the pond. The outflow from Detention Pond A will not exceed the 10 -year historic flow rate. 5.2 Offsite Drainage Offsite drainage for Basin OS -1A will be collected and conveyed in a perimeter ditch along the west and south property lines. A culvert conveys this discharge under the access road near the site entrance. The ditch slope is approximately 1 %. This channel shall be lined with TRM. The top width of the flow in the channel (4.76 feet) is greater than the width of a level spreader that spreads flow out at 1 cfs/LF (2.63 feet). Since the water surface top width is greater than the level spreader, a level spreader is not required to diffuse flow prior to release downstream. Offsite drainage for Basin OS -2A will be collected and conveyed in a perimeter ditch along the north property line. The ditch slope is approximately 0.5%. This channel shall be lined with TRM. The top width of the flow in the channel (4.84 feet) is greater than the width of a level spreader that spreads flow out at 1 cfs/LF (1.94 feet). Since the water surface top width is greater than the level spreader, a level spreader is not require to diffuse flow prior to release downstream. 5.3 Onsite Drainage The proposed development was divided into multiple drainage basins that drain to the detention pond onsite. The discharge location from the detention pond has been designed so that the runoff drains to the historic drainage point (POA A), located on the southeast side of the site. The 10 -year release from the detention pond will not exceed the allowable release rate. Drainage Basin 1 includes the northern portion of the site. Runoff from Basin 1 drains into a Drainage Channel that conveys runoff along the northeast corner of the site, and then south into Detention Pond A. This basin contains multiple site buildings and a portion of the pipe rack. Detention Pond A is in the southeastern part of the developed portion of the site and discharges at POA A. See Appendix A- 4 Developed Drainage Plan. Drainage Basin 2 includes the northwestern portion of the site. Runoff from Basin 2 drains through a drainage channel to a culvert thatconveys runoff under the onsite access road. This basin contains multiple site buildings and a portion of the pipe rack. After passing under the onsite access road, the drainage channel also intercepts flow from Basin 4 and is conveyed to Detention Pond A.

Runoff from Basin 3 flows overland to the east into Detention Pond A. This basin contains a portion of the site road and the laydown area. Drainage Basin 4 includes a central portion of the site. Runoff from Basin 4 flows is collected within the channel and flows to Detention Pond A. This basin contains site buildings, the access road, and a portion of the laydown area. Drainage Basin 5 includes the southeastern portion of the site. Runoff from Basin 5 flows overland to the south into Detention Pond A. This basin primarily consists of the site access road, detention pond and site buildings. The soils on site are loose and non -cohesive sands and barns. This soil is expected to be easily eroded by wind or rainfall runoff Stabilization of the ground is needed to reduce the degree of wind and water erosion over time. Vegetation is not recommended to stabilize the ground after construction completion due to the risk of fire. A pea gravel or other loose aggregate product is recommended to prevent the hare soil. Magnesium chloride may be used for dust suppression, but could significantly increase the runoff quantity over the crushed rock. Other commercial products exist to stabilize the disturbed ground, but these products may be flammable and not recommended for use at this site. The Developed Drainage Plan is available in Appendix A-4 Developed Drainage Plan. The following table provides the peak flow rates for the onsite drainage basins.

Detention Pond A is designed to detain the total volume of the 100 -year developed storm event for the entire site development. It is Green Rh er's preferred practice to trap stormwater prior to release so that it may be checked for sheen, therefore the pond is design to contain the total 100 -year storm runoff. A minimum of one foot of freeboard will be provided for each detention pond for the 100 -year storm event. The required Water Quality Control Volume (WQCV) will be contained within the detention volume for the detention pond. Outflow from the detention pond will discharge through an outlet structure with water quality treatment plate to slow the drain time of the detention ponds to allow sediment to settle before the water is discharged from the site, Preliminary Drainage Report 6 June 2018 Colt Liquid Receipts Facility o:\Projects\Lnngment435719\200-35719-18005\Does\Reports\Drainage Report\DrainageReport_C"olt.docx The pond outlet structure contains an 8" diameter outlet pipe. s e outlet pipe will be restricted using a metal plate that is attached to the outlet box to cover a portion of the outlet pipe. The restrictor plate elevation is set at a specific elevation to control the release rate of the detention pond. The restrictor plate elevation has been set so that the peak release rate from the site does not exceed the 10 -year historic flow rate in accordance with Weld County Code and Urban Storm Drainage Criteria Manual, volumes 1, 2, and 3. Design calculations for the detention pond and outlet pipe are presented in Appendix C-4, Erosion control measures, such as rip -rap, will be provided at the detention pond outlet and culvert and swale outlets to protect against erosion. The following table presents a summary of information pertaining to the detention ponds onsite.

Stormwater discharge from the detention ponds is designed to not exceed the 10 -year historic runoff rate in accordance with the Weld County Code Design Criteria and Construction Specifications. The release rate from the detention ponds will be achieved using flow restriction plates on the detention pond discharge pipes so that release rates from the detention pond does not exceed the 10 -year historic runoff rate. Detention ponds will discharge to the historic drainage point located along the eastern portion of the site. Proposed detention ponds will comply with the following criteria: 1. Runoff must be sampled, tested and reported in compliance with CDPHE stormwater permit requirements. 2. Runoff will be released in a location to maintain the historic flow patterns 3. Runoff for the 100 -year storm will be released at the 10 -year pre -project rate. Drain time for each ofthe ponds was evaluated using the UDFCD detention pond worksheets. Colorado drainage law requires the discharge of 99% of all runoff from all storm events in 120 hours. 5.5 Drainage Infrastructure Maintenance Satisfactory operation of onsite drainage components requires scheduled maintenance throughout the life of the site. The following are recommendations for maintenance and inspection that are drawn from the Southeast Metro Stormwater Authority (SEMSWA) in Denver, Colorado. Preliminary Drainage Report 7 June 2018 Colt Liquid Receipts Facility o:\Projects\Lnngment435719\200-35719-18005\Does\Reports\Drainage Report\DrainageReport_C"olt.docx • onsite personnel should be tasked with developing a schedule that reminds them to evaluate all drainage components onsite. • Routinely (monthly basis) inspect ditches, ponds, culverts, outlet structures, riprap, etc. to ensure locations are free from debris and excess vegetation. ■ Ensure riprap, culverts, and outlet structures are not compromised. Repair if needed. • Frequency of inspection may need to be more frequent in the first year or two as the site is established. Facilities should be inspected following any storm event. • When mowing, collect clippings and all other trimmings and take offsite for disposal or dispose with trash onsite; do not leave in the pond or ditch. • Remove vegetation adjacent to outlet works that may interfere with operation; note if noxious weeds are present and notify supervisor to schedule treatment/removal. • During inspection, report damage/compromise to side slopes, pond banks, inlet pipe, trickle channels, outlet structure. Prepare a repair schedule and complete repairs. It is important to limit use of fertilizers and pesticides in andaround the ponds and ditches to minimize entry into pond and subsequent downstream waters. • For detention ponds, every 6 months or so, the accumulated sediment should be removed from the bottom of the outlet structure and the pond depths checked at several points. If the depth of the accumulated sediment is greater than 25 percent of the original design depth, sediment should be removed. Accumulated sediment, over time, will reduce the capacity of the pond and may cause site flooding if not maintained. A typical checklist for operators to use during inspections is as follows: • Has trash accumulated within the ponds and ditches? • Evaluate vegetative cover to ensure it does not compromise ditch or pond area. • Ts there evidence of erosion or instability on pond and ditch slopes? • Is there any sedimentation within the pond, in ditches, and in culverts? • Is there any settling and/or cracking in permed areas? • Are there any upstream or downstream conditions that could impact drainage? Depending on the evaluation, discrepancies should be addressed and fixed as soon as possible. Neglecting repairs may compromise drainage through the site. 6.0 CONCLUSION This report was prepared in compliance with the Weld County Code and the Urban Storm Drainage Criteria Manual, volumes 1, 2, and 3. The proposed drainage system for the improvements to the Colt Station Liquid Capture Facility site will provide detention for the developed section of the site, releasing flows from the site at the 10 -year historic rate. Releases are as near to the points of design as practical and are not expected to increase adverse impacts on downstream property owners. This Final Drainage Report is being submitted to Weld County for review and approval.

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.gavlwpsl portallnreslmainlsoils/health!} and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.govllacator/app?agency=nres) or your N RCS State Soil Scientist (h ttp ://www. n res .0 sd a. g ovlwpsrpo rtal/nres/detail /so i is/conta ctu s!? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the N RCS 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.

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 11 Custom Soil Resource Report landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary► to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Weld County, Colorado, Southern Part 44 Olney loamy sand, 1 to 3 percent slopes Map Unit Setting National map unit symbol: 362r Elevation: 4,600 to 5,200 feet Mean annual precipitation: 11 to 15 inches Mean annual air temperature: 46 to 54 degrees F Frost -free period: 125 to 175 days Farmland classification: Farmland of statewide importance Map Unit Composition Olney and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

TETRA TECH MEMO To: Evan Pinkham, Weld County Public Works Cc: Dawn Anderson From: Gene Coppola, P.E. Date: June 26, 2018 Subject: Traffic Narrative, Colt Station Liquid Capture Facility, Weld County, Co I have developed and reviewed the site -generated traffic associated with the proposed Colt Liquid Receipts Facility (Facility) in Weld County. The Facility will be located along the north side of CR 34 1/2, west of CR 49. The Facility will capture drip condensate from gas delivered to the site by pipelines. Gas from this Facility will be stabilized and delivered to other parties in the nearby areas using pipelines. In the event the existing pipeline is not available, the stabilized natural gas liquid will be transported by truck. An area for a laydown yard is also being reserved in case it is needed by Green River Devco. The site will be unmanned, but will be operational 24 hours per day, seven days per week, 365 days per year. One to two employees may visit the site each day to perform testing and maintenance. These employees will arrive at the site using pick-up trucks. Site access will be provided by an existing driveway to CR 34 1/2. This driveway is located about one -quarter mile west of CR 49. Construction traffic is estimated at up to 5 trucks per day and 20 - 25 pick-up trucks per day for five to six months. Routine site traffic is expected to be two pick-up trucks per day. Occasionally, additional site traffic may visit the site. This includes: • Up to 4 semi -trucks per day when the laydown yard is being used. • Up to 4 tanker trucks per day when the pipeline is not available. Ongoing site traffic is expected to be in the range of 5 vehicles per day (1-2 employee vehicles and 2-4 trucks). All site traffic is expected to enter the site from CR 34 1/2 after turning onto CR 34 1/2 from CR 49. The reverse route is expected for vehicles leaving the site. The site peak hour is difficult to estimate since most vehicles will not be only visiting this site but other Noble facilities in the general area. The peak hour is expected to occur in the morning when employees arrive at work and are dispatched. Site traffic is expected to disperse to the various areas and become less concentrated as the day goes on. Daily traffic on CR 34 1/2, west of CR 49, is 130 vehicles per day with traffic on CR 49 being in the range of 5,700 vehicles per day. Daily traffic is based on traffic count information obtained from Jerry Steinbar with Weld County. With the addition of site traffic, routine daily traffic using CR 34 1/2, west of CR 49 will be 140 vehicles per day with 5,760 vehicles per day on CR 49. Given these estimates, traffic using the area roadway system will remain modest and can be easily served by the existing roadway system. I trust this narrative will address County needs concerning traffic associated with Noble Energy's Colt Liquid Receipt Facility. Please contact me if you have any questions or need further assistance.

When the Colt Station Liquid Capture Facility is operating, it is expected to have a very minimal impact on the neighbors. It is about 1000 feet away from the nearest home and the facility will not generate a lot of traffic, noise, or light during normal operations. The point in time when the facility could have the greatest impact is when it is under construction and there is more traffic associated with that construction. Green River's plan for reaching out to the community is to communicate with the neighbors that are within 500 feet of the half section of land on which the facility will be located. This is a generous notification area considering the only land within 500 feet of the actual facility is land owned by OGG&S and the Strohs, the owners of the land that Green River has leased land from for the facility. By July 16, 2018, Green River will mail the neighbors a notice about the application which will include a description of the project and a map to illustrate the location of the project and what is proposed. Green River will ask that the neighbors contact them if they have any questions or concerns about the application. The initial response received from the neighbors will help Green River decide if additional steps are needed. Green River may have individual conversations with neighbors either in person or on the phone or they may choose to host a community meeting if they determine that would be a more effective way to communicate. Green River's goal will be to identify any concerns that neighbors have, and to work with them to try and find a way to address the concerns ahead of time so that the neighbors feel comfortable with the proposed facility. In addition, Green River will develop a way to communicate with the neighbors in the future as the facility is operating so that they are being respectful neighbors. The exact plan for long-term communications has not yet been determined, but it will be decided prior to the public hearing on this project so that information can be shared. TETRA TECH Page 111 Hello
