Explain, in detail, the proposed use of the property: The proposed use of this Right of Way (ROW) is a 16" natural gas pipeline. This gas pipeline is approximately 1,700 feet long and is located south of WCR 12 and east of WCR 35. It begins at the Discovery Ft. Lupton Gas Plant, runs west to the 2.5 -acre new Residue Gas Meter Site and then to the Kinder Morgan 5A, 5B, and 5C gas transmission pipelines. The meter site will be divided by a fence, with one side containing all of the Discovery equipment and the second side containing all of the Kinder Morgan equipment. The Discovery side will contain a pipeline pig receiver, two filter units and a storage tank to remove any liquids that may form in the gas pipeline between the Gas Plant and Meter Site. There will be a driveway along the north side of the site for normal operations and for truck access and egress during tank draining activities. The Kinder Morgan side will contain a gas meter with an electrical gas measurement building, a flow control valve and the tie-in connections to their three pipelines. Both sides will have a communication antenna with heights below 15 feet to allow the companies to transmit measurement and control data to their respective remote control centers. The closest communication tower is approximately 1,000 feet from the northeast corner of the site, and because there is no right-of-way available to reach it, the decision was made to locate the antennas on site. Kinder Morgan has not determined their final equipment layout at this time and, as such, none of their equipment has been included in the site layout. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan: Response: Section 22-2-10(D) of the Weld County Code states that "extraction of natural resources is an important part of the economy of the County." The proposed 16" natural gas pipeline will contribute to the expansion of the county's industrial economic base by transporting valuable resources and contributing to the increased capacity for future marketing of natural gas production in Weld County. Section 22-2-80(C) states that "The land use applicant should demonstrate that the roadway facilities associated with the proposed industrial development are adequate in width, classification, and structural capacity to serve the development proposal." The new pipeline development proposal will not affect traffic in such a way as to conflict with current transportation infrastructure, as the pipeline will be built within a Right -of -Way and any roads will be bored under, rather than trenched across. The Residue Gas Meter Site will utilize existing roadways for operations and transportation personnel to reach the site; however, site visits will be infrequent. A traffic study will be performed to determine what effect the site will have on the existing roadways normal use. The pipeline will comply with all federal, state, and local policies and legislation per Section 22-2-80(E). Section 22-4-30(D2) states that "applications for new developments should include provisions for adequately handling drainage and for controlling surface erosion and sedimentation within the site itself". Appropriate BMPs will be used during the construction of the pipeline and meter site to prevent harmful erosion and drainage issues and the landscape will be returned to its original condition when construction is complete as much as possible. An SPCC study and drainage report will be performed for the meter site to ensure that all stored liquid can be adequately contained in the event of a spill to protect the surrounding environment. The DISCOVERY MIDSTREAM PARTNERS USR. QUESTIONNAIRE site will be graded as required by the drainage report and permanent containment will be installed around the tanks. Section 22-4-50 states that "land use applications should demonstrate future impacts on current air quality". There will be several venting locations throughout the site, on the receiver for maintenance activities, and on the tanks and the filter vessels for overpressure protection. An emissions study will be performed and the site will be designed and permitted per the State's Air Pollution Control Program and Section 22-4-40. Section 22-4-100 states that "the county expects businesses...to prevent negative impacts on human health and the environment from waste processing or disposal". Because the pipeline and facility and unmanned, there is no solid waste expected for either. The pipeline is below grade and will not produce any waste outside of the meter site. The meter site will have produced water and liquid condensate waste which will be stored in above- ground tanks and trucked off -site. All such waste will be disposed of in an appropriate location per the requirements of Section 22-4-110. Section 22-5-90(C) states that, due to the overcapacity of pipelines and refineries in the state, there is an increase in the need for transportation and storage. The most efficient and safe way to transport natural gas is by pipeline because it negates the need for the transportation of this resource by truck. This benefits the county by allowing for less impact on county roads, minimal impact on land, better air quality, and the economic advantages that pipeline infrastructure brings. 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: Section 23-3-40 indicates that oil and gas storage facilities, support, service, and pipelines are acceptable as a Use by Special Review within the Agricultural Zone District. The meter site and above grade pipeline appurtenances will be designed to comply with the requirements of Section 23-2-240 and operated per the requirements of Section 23-2-250. As required by Section 23-2-250(C2) the Residue Gas Meter Site is approximately 780' away from the nearest residential structure at its southwest corner. All other closest surrounding residences are approximately 1,400' to 1,900' removed from the site boundaries. As defined by Section 23-4-830 "telecommunication antenna towers are allowed as a use by right, accessory uses, subject to Zoning Permit for telecommunication antenna tower requirements, or as a Use by Special Review Permit, per the height guideline." Because both antenna poles will be under 35 feet in height, they fall under use by right as defined by the section. 4. Describe what type of land uses surround the site. Explain how the proposed use is consistent and compatible with surrounding land uses. The land usage surrounding the site in question is primarily agriculture. The new pipeline will be routed within existing rights -of -way not interfere with agricultural production. The gas meter site is located along the southern boundary of the parcel it is located in to minimize its impact on agricultural activities in the area. The pipeline will be regulated and compliant with environmental code. DISCOVERY USR QUESTIONNAIRE 5. What are the hours and days of operation? The pipeline and site will be in operation for twenty-four (24) hours a day, seven (7) days a week. 6. List the number of full time and/or part time employees proposed to work at this site: These will be an unmanned facility and there will be no full time or part time employees post construction. 7, If shift work is proposed, include the number of employees per shift: Shift work will not be employed at this site. 8. List the number of people who will use this si₹e. Include contractors, truck drivers, customers, volunteers, etc.: Response: Contractors will be used on the site for initial construction. There will be intermittent access to the ROW and meter site for maintenance and operation activities by both Discovery Midstream employees and third -party contractors. 9. If this is a dairy, livestock confinement operation, kennel, etc., list the number and type of animals: No animals will be onsite. 10. Describe the type of lot surface and the square footage of each type. (e.g. asphalt, gravel, landscaping, dirt, grass, buildings): The pipeline will be cut and filled with the original grading surface. The portion of the ROW that will be used for site access will be top graded with ≥6 inch road base and the remaining portion will be re -seeded after completion of the pipeline to return the area to original condition. The site will be cut and filled to produce a level foundation and will be filled with the original grading material with Z6 inch of road base on top to cover the 2.5 -acre site. 11. How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed? : The pipeline will run within the ROW and will have no parking spots. The meter site will be an unmanned facility and, as such, will have no designated parking spaces on site. However, there will be room for parking within the site limits for operations and maintenance personnel to use. 12. Explain the existing and proposed landscaping for the site: The existing site is an agricultural field. The pipeline will be cut and filled with the original grading surface. The ROW will also be re -seeded after completion of the pipeline to return the area to original condition. The meter site and access ROW will be filled with road base after completion and all above grade piping will be painted in desert tan to blend into the surrounding environment. Fencing will be installed around the perimeter of the site. DISCOVERY USR QUESTIONNAIRE 13. Describe the type of fence proposed for the site (e.g. 6 -foot chain link with earth tone slats): The pipeline will be below grade and therefore not require a fence. The fencing around the site will be 7 -foot chain link fencing with Carlsbad Canyon Tan slats. 14. Describe the proposed screening for all parking and outdoor storage areas: No screening beyond fencing will be implemented. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs: Upon termination of the Use by Special Review, the facility and the proposed development area will be returned to its original state. All equipment, grading, and structures will be evaluated at that time for demolition and reclamation. 16. Who will provide fire protection to the site?: Fire protection to be provided by Southeast Weld 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: The below -grade pipeline east of the existing dirt road will be re -seeded upon completion of construction. The meter site and ROW to the west of the existing dirt road will be filled with road base and all above grade piping will be painted immediately following all integrity testing activities. Fencing will be installed around the perimeter of the site as soon after construction as practicable. Engineering Questions: 1. Describe how many roundtrips/day 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): More than one passenger vehicle per day is not expected. There will be intermittent vehicle access for maintenance activity, but it is unlikely that this will occur daily. There will be intermittent commercial vehicle access in order to transport liquid from the storage tanks off -site. 2. Describe the expected travel routes for the site traffic: The pipeline and meter site is located within the boundaries created by WCR 10, 12, 31, and 35. It can be accessed via a dirt access road located to the west of the meter site that can be accessed from the north via WCR 12 or from the south via WCR 10. This access road intersects with the pipeline ROW, which can be followed to the meter site. (See the attached map for details.) 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.): DISCOVERY MIDSTREAM PARTNERS USR QUESTIONNAIRE Access to the pipeline can come from either the north or south direction and access to the meter site will come from the east along the right of way. It is anticipated that 50% will come from the north and 50% will come from the south. 4. Describe the time of day that you expect the highest traffic volumes: The traffic volume will be minimal. For normal operations, the traffic that does occur will be within daylight hours (7 a.m. to 7 p.m.). 5. Describe where the access to the site is planned: The pipeline can be accessed from the north or south approximately half way through the route and the site can be accessed from the east where the ROW enters the site boundary. 6. Drainage Design: A drainage report will be submitted for the meter site based on Weld County requirements. A. Does the site qualify for an exception to storm water detention? If so, describe in a drainage narrative the following: 1. Which exception is being applied for and include supporting documentation. Per Weld County USR Pre -Application meeting minutes, an exception for pipelines is requested per 1.a.5. 2. Where the water originates if it flows onto the property from an offsite source Because the Prairie Dog route has a ridge along the center of the route, the surface flow will be split approximately in half. On the eastern half of the pipeline, the surface flow will be generally west to east, from the high point midway along the pipeline toward the low point at the pipeline start point. On the western half of the pipeline, the surface flow will generally be east to west, from the high point along the pipeline toward the meter site. Surface flow on the meter site will also travel east to west from the pipeline entrance to the low point on the western border of the site. Reference attached map (PDMF-AM-002). 3. Where it flows to as it leaves the property Reference attached map (PDMF-AM-002). 4. The direction of flow across the property Reference attached map (PDMF-AM-O02), 5. If there have been previous drainage problems with the property DISCOVERY USR QUESTIONNAIRE No known drainage problems exist. Environmental Health Questions: 1. What is the drinking water source on the property? Due to the intermittency of personnel on -site after construction, a permanent source of drinking water will not be necessary. During construction, bottled water will be provided for the construction crew. Personnel and contractors will be responsible for bringing their own drinking water after construction. 2. What type of sewage disposal system is on the property? There is no existing sewage disposal system on the property. Portable toilets will be used during construction. Due to the intermittency of personnel on site, a sewage disposal system will not be installed. 3. If storage or warehousing is proposed, what type of items will be stored? : There will a single storage tank located on the meter site to collect produced water and condensate drainage from the process. The carbon steel storage tank will be 9'-6" in diameter and 8' tall and will be capable of storing 100 bbl. of liquid. 4. Describe where and how storage and/or stockpile of wastes, chemical, and/or petroleum will occur on this site: General trash will be gathered and disposed of in dumpsters during the construction phase. Any flammable or oily rags/debris will be disposed of in vapor safe, metal bins. No such waste is anticipated to exist post - construction. Water and condensate drainage will be collected and piped to a storage tank located on site. The fluid from this tank will be transported off -site via truck as needed. S. If there will be fuel storage on site, indicate the gallons and the secondary containment. State the number of tanks and gallons per tank: No vehicle or equipment fuel will be stored on site. 6. if there will be washing of vehicles or equipment on site, indicate how the wash water will be contained: There will be no vehicle washing facility for this project. 7. If there will be floor drains, indicate how the fluids will be contained: There will be no floor drains for this pipeline project. 8. Indicate if there will be any air emissions (e.g. painting, oil storage, etc.): The pipeline will be below grade and will only produce air emissions will be from occasional pipeline depressurization during maintenance operations. DISCOVERY MIDSTREAM PARTNERS USR QUESTIONNAIRE The meter site will have several sources of air emissions that will be monitored and designed per the COGCC guidelines. These sources will be from the pressure relieving valves on the condensate storage tank, the coalescing filter units, and the meter skid on the Kinder Morgan side which are for overpressure protection, and from vents of the receiver located on site from depressurization during pipeline maintenance operations. 9. Provide a design and operations plan if applicable (e.g. composting, landfills, etc.): The pipeline operations will be conducted as follows: 1. The pipeline will be installed within the ROW via trenching and boring during the construction phase. 2. The pipeline will be hydrostatically pressure tested to ensure pipeline integrity. 3. Upon completion of the pipeline installation, the surrounding environment will be restored per right-of-way agreements. The pipeline will be cut and filled with the original grading surface. The ROW will be re -seeded to return the area to the original condition. 4. The pipeline will transport natural gas from the main trunk line to the Residue Gas Meter Site. Operations will monitor product movements from the control room and will be available to open or close valves where necessary. The Residue Gas Meter Site operations will be conducted as follows: 1. The meter site will be installed within the purchased site boundaries via cutting, filling, and trenching during the construction phase. 2. Once the site is constructed, all equipment, except the storage tank, and on -site piping will be hydrostatically pressure tested to ensure the integrity of the system. 3. Upon completion of the site, the grade will be restored using the original grading surface as much as possible and will be topped with ≥6 -inches of road base. Fencing will be installed around the perimeter of the site and the piping and equipment will be painted to blend into the surrounding environment as much as possible. 4. Gas entering the meter site will flow through a coalescing filter separator then delivered to the Kinder Morgan gas measurement facility. Any free or entrained liquids will drop out at the filter separator and pushed, via pressure, to the storage tank. 5. The liquid levels in the tank and vessels will be monitored and controlled automatically and manually. Operations will be able to monitor product movements from the control room and will be available to open or close valves if necessary. Operations will also be present to empty the tank containing liquids removed by the filter separator. 10. Provide a nuisance management plan if applicable: Not Applicable 11. Additional information may be requested depending on type of land use requested: Not Applicable Building Questions: 1. List the type, size (square footage), and number of existing and proposed structures. Show and label all existing and proposed structures on the USR drawing. Label the use of the building and the square footage. DISCOVERY MIDSTREAM PARTNERS USR QUESTIONNAIRE There will be one building located on site, on the Kinder Morgan side of the property. This will be an electrical gas measurement building and will contain sampling equipment and a gas chromatograph. The building will be 8 -feet wide, 12 -feet long, and approximately 10 -feet high, and will have a square footage of 96 ft2. Kinder Morgan has not determined their final equipment layout at this time, so this building is not shown in the layout drawing. 2. Explain how the existing structures will be used for this USR.

Applicant's name and telephone number. Discovery DJ Services, LLC Lito White 303.717.9808 B. Address of the applicant and general office. Discovery DJ Services, LLC 7859 Walnut Hill Lane, Suite 335 Dallas, TX 75230 C. Summary statement of the project, to include, when applicable: 1. The source, capacity, sire, destination, and type of facilities, support structures, lines, etc., involved. The proposed use of this Right of Way (ROW) is a 16" natural gas pipeline. This gas pipeline is approximately 1,700 feet long and is located south of WCR 12 and east of WCR 35. It begins at the Discovery Ft. Lupton Gas Plant, runs west to the 2.5 -acre new Residue Gas Meter Site and then to the Kinder Morgan 5A, 5B, and 5C gas transmission pipelines. The meter site will be divided by a fence, with one side containing all of the Discovery equipment and the second side containing all of the Kinder Morgan equipment. The Discovery side will contain a pipeline pig receiver, two filter units and a storage tank to remove any liquids that may form in the gas pipeline between the Gas Plant and Meter Site. There will be a driveway along the north side of the site for normal operations and for truck access and egress during tank draining activities. The Kinder Morgan side will contain a gas meter with an electrical gas measurement building, a flow control valve and the tie-in connections to their three pipelines. Both sides will have a communication antenna to allow the companies to transmit measurement and control data to their respective remote control centers. The closest communication tower is approximately 1,000 feet from the northeast corner of the site, and because there is no right-of-way available to reach it, the decision was made to locate the antennas on site. Kinder Morgan has not determined their final equipment layout at this time and, as such, none of their equipment has been included in the site layout, 2. A detailed report shall be submitted which includes information on the following items. a. A description of the pipeline -- Natural Gas. The proposed 16" pipeline will be constructed for natural gas gathering, will be approximately 1,700 feet in length, and will have an estimated daily flow rate of up to 200 MMSCFD, The pipeline will transport natural gas from the Discovery Ft. Lupton Gas Plant to the Discovery Residue Gas Meter Site, where it will be filtered and metered before entering the Kinder Morgan 5A, 5B, and 5C gas transmission pipelines. It will run primarily below grade apart from a launcher and receiver installed at each end of the pipeline to allow for cleaning operations. The pipeline will be of carbon steel construction, and below -grade piping will be installed with a fusion bonded epoxy (FBE) coating and an impressed current cathodic protection system to prevent corrosion. DISCOVERY MIDSTREAM PARTNERS USR Application Requirements, Sec. 23-2-510 b. A description of the preferred route or site and reasons for its selection. This pipeline is located within the boundaries made by the four WCRs 10, 12, 31, and 35. It can be accessed via an existing dirt road that extends from WCR 10 to WCR 12 and intersects with the pipeline ROW (see the attached map for details.) Access to the pipeline can come from either the north or south depending on whether the WCR 10 or WCR 12 is used. The meter site can be accessed using the ROW for the pipeline to enter the east side of the site. This access is the only way to approach the site location without creating a new access road. The size of the meter site parcel is 2.5 acres located at the pipeline terminus. c. Procedures to be employed in mitigating any adverse impacts of the proposed routes or sites. During construction, waste materials will be handled, stored, and disposed in a manner that controls blowing debris, and other potential nuisance conditions. Dust will be confined to the property as much as possible. Water trucks will be used to mitigate dust in dry situations and matting will be used in areas where equipment or trucks will sink and leave a major impact on the ground. Post construction, any solid waste materials created from maintenance activities will be handled and stored by operations personnel while on site and will be removed from the site immediately after any maintenance activities; no solid waste will be permitted to remain on site. Liquid waste created by the process will be piped to an on -site storage tank and will be trucked off -site to a final disposal facility on a regular basis. d. An outline of the planned construction, including startup and commissioning schedule, to include the number of stages and timing of each. Construction is scheduled to begin in April 2018 and continue for approximately 2 months. The project will be continual and not be completed in phases. Construction of the pipeline will consist of ROW clearing, pipe layout, trenching, lowering, backfilling, hydro testing and returning the ROW to its original condition. Construction of the site will consist of cutting, filling and trenching, equipment setting and piping, electrical installation, backfilling, hydro testing, final grading, painting and fence installation. e. Information of any public meeting conducted, to include the location, date, time, attendance and method of advertising. A public meeting will be conducted. Pamphlets will be mailed to landowners within 500 feet of the ROW and site if any. f. A description of the hazards, if any, of fire, explosion, and other dangers to the health, safety, and welfare of employees and the public. This pipeline will be buried at a minimum of 4 feet below grade. One of the possible hazards may be caused by third -party damage, such as the pipeline being struck during trenching of a future project within the ROW. To mitigate the potential for third -party damage: DISCOVERY USR Application Requirements, Sec. 23-2-510 A damage prevention plan in accordance with 49 CFR 192 will be in place. The pipeline will be registered with Colorado 811/One-Call and a public awareness program in accordance with 49 CFR 192 will be in place. The pipeline will have above -grade pipeline markers in accordance with 49 CFR 192. Documentation, as prescribed by 49 CFR 192, will be maintained. Another potential hazard is corrosion. In order to prevent corrosion, the pipeline will have: - Fusion bonded epoxy coating Cathodic protection system installed and maintained per 49 CFR 192 - Regular cleaning tools pushed through the pipeline Launchers and receivers capable of accepting internal inspection tools To provide protection in the event of a pipeline leak, the pipeline will be equipped with a leak detection system and pipeline shutdown valves. One of the hazards for the meter site comes from the potential of equipment being struck by a vehicle driving to or within the site. To protect the site from this hazard: A damage prevention plan in accordance with 49 CFR 192 will be in place. - Fencing will be installed around the perimeter of the site to prevent any vehicles driving in the surrounding area from entering the site without permission. - Bollards will be installed around equipment close to the road around the perimeter of the process area to protect the equipment from being unintentionally struck by drivers within the site. One of the major hazards for the meter sites comes from the sparking of electrical equipment or from static electricity in areas where volatile gases may be present. To protect the site from this hazard: - A hazardous areas classification will be created to determine where gases are likely to be present and install appropriate electrical equipment for those areas as well as create appropriate lockout/tag out procedures for operations personnel. - A site -wide grounding system will be installed to keep all equipment grounded and limit the possibility of creating unintentional sparks. - A lightning protection system will be installed to protect the site from lightning strikes Another potential hazard for the meter sites is the possibility of a pipeline rupture due to freezing and/or overpressure. To protect from this hazard: All above ground piping that may hold liquids that could freeze will be insulated and heat traced to prevent freezing in cold weather. - Lockout/tag out procedures will be in place to prevent operations personnel for closing manual valves that may result in a blocked -in scenario. - Pressure Safety Valves (PSVs) will be in place on pressure vessels and equipment and will be appropriately set to release pressure in the event of an unexpected pressure spike. - High-pressure alarms and shutdowns are in place to protect the facility in the event of an unexpected pressure increase. Both the pipeline and site will also be monitored 24 hours/per, 365 days/year from a remote operations center and will be equipped with automatic alarm and shutdowns in the event of upset conditions. DISCOVERY MIDSTREAM PARTNERS USR Application Requirements, Sec. 23-2-510 g. A description of emergency procedures to be followed in case of a reported failure or accident involving the proposed pipeline. Such an outline shall include actions, if any, required of public officials, including fire and police officials, and the names and telephone numbers of appropriate company officials to notify if an accident or failure should occur. Please reference the attached Emergency Response Plan. h. A description of the method or procedures to be employed to avoid or minimize the impacts on irrigated agricultural land. The pipeline has been routed to minimize impact to any irrigated fields by locating the ROW along property lines where no irrigation will take place. The site is also located at the edge of the property to minimize any impact on existing fields. All equipment and personnel will stay within the ROW and on the site property at all times. All impacted ground outside of the site perimeter and within the entire ROW will be reseeded and restored back to original grade per the land agreements once construction has been completed. i. A discussion of how the proposal conforms with the guidelines of Chapter 22 of this code and any other applicable code provision or ordinance in effect. Section 22-2-10(D) of the Weld County Code states that "extraction of natural resources is an important part of the economy of the County," The proposed 16" natural gas pipeline will contribute to the expansion of the county's industrial economic base by transporting valuable resources and contributing to the increased capacity for future marketing of natural gas production in Weld County. Section 22-2-80(C) states that "The land use applicant should demonstrate that the roadway facilities associated with the proposed industrial development are adequate in width, classification, and structural capacity to serve the development proposal." The new pipeline development proposal will not affect traffic in such a way as to conflict with current transportation infrastructure, as the pipeline will be built within a Right -of -Way and any roads will be bored under, rather than trenched across. The Residue Gas Meter Site will utilize existing roadways for operations and transportation personnel to reach the site; however, site visits will be infrequent. A traffic study will be performed to determine what effect the site will have on the existing roadways normal use. The pipeline will comply with all federal, state, and local policies and legislation per Section 22-2-80(E). Section 22-4-30(D2) states that "applications for new developments should include provisions for adequately handling drainage and for controlling surface erosion and sedimentation within the site itself". Appropriate BMPs will be used during the construction of the pipeline and meter site to prevent harmful erosion and drainage issues and the landscape will be returned to its original condition when construction is complete as much as possible. An SPCC study and drainage report will be performed for the meter site to ensure that all stored liquid can be adequately contained in the event of a spill to protect the surrounding environment. The site will be graded as required by the drainage report and permanent containment will be installed around the tanks. Section 22-4-50 states that "land use applications should demonstrate future impacts on current air quality". There will be several venting locations throughout the site, on the receiver for maintenance activities, and on the tanks and the filter vessels for overpressure protection. An emissions study will be performed and the site will be designed and permitted per the State's Air Pollution Control Program and Section 22-4-40. DISCOVERY MIDSTREAM PARTNERS USR Application Requirements, Sec, 23-2-510 Section 22-4-100 states that "the county expects businesses...to prevent negative impacts on human health and the environment from waste processing or disposal". Because the pipeline and facility are unmanned, there is no solid waste expected for either. The pipeline is below grade and will not produce any waste outside of the meter site. The meter site will have produced water and liquid condensate waste which will be stored in above -ground tanks and trucked off -site. All such waste will be disposed of in an appropriate location per the requirements of Section 22-4-110. Section 22-5-90(C) states that, due to the overcapacity of pipelines and refineries in the state, there is an increase in the need for transportation and storage. The most efficient and safe way to transport natural gas is by pipeline because it negates the need for the transportation of this resource by truck. This benefits the county by allowing for less impact on county roads, minimal impact on land, better air quality, and the economic advantages that pipeline infrastructure brings. j. A Decommissioning Plan. When the pipeline is decommissioned, Discovery DJ Services will run cleaning pigs, and then run nitrogen through the pipeline to purge the pipeline of any remaining fluids. The pipeline will be left in place and disconnected from the source of natural gas, sealed and capped, and permanently removed from service. All equipment, grading, and structures will be evaluated at that time for demolition and reclamation. This procedure will comply with all applicable laws and codes, including, but not limited to, 49 CFR 192. k. A description of any haul routes during construction, identifying the roads and bridges involved and the weight of the loads. Reference attached map (PDMF-AM-003). 1. Any other information determined to be necessary by the Department of Planning Services or its authorized representative to ensure the protection of the health, safety, and welfare of the inhabitants of the county. Discovery DJ Services, LLC will respond with any additional information required by Weld County. DISCOVERY TRAFFIC MEMO OVERVIEW This traffic memo is prepared to accompany the Use by Special Review application for the Prairie Dog gas pipeline and meter project by Discovery Midstream Partners. The subject site is located south of WCR 12 and east of WR 35, It begins at the Discovery Ft. Lupton Gas Plant, runs west to the 2.5 -acre new residue gas meter site and then to the Kinder Morgan 5A, 5B, and 5C gas transmission pipelines. This memo provides an overview of the long-term traffic associated with the proposed use. A full Transportation Impact Study will not be necessary as the expected traffic to the site will be fewer than 21 trips per day or 7 trucks per day. If the expected traffic for the site increases in the future, the TIS will be completed at that time. BACKGROUND The pipeline and meter site is located within the boundaries created by WCR 10, 12, 31, and 35. The use of this site will be to build a natural gas pipeline and meter station.

Stephens & Associates, Inc. Drainage Report Prairie Dog Meter Station Weld County, Colorado 1. Introduction Discovery Midstream Partners (Discovery) proposes to install a new meter station in Section 11, TO1N, N, RGG , Weld County, Colorado (the site). The site is approximately 265 acres in area and is bounded on the south by Weld County Road (WCR) 10. The facility will serge as an area for the installation of flow meters and related equipment. This drainage report summarizes the stormwater infrastructure to be installed for the proposed development, and has been prepared in accordance with Weld County regulations and the Urban Drainage and Flood Control District (UDFCD) guidelines. 2. Scope of Work The following infrastructure will be installed as part of this development: Gravel -surfaced driving areas a A small (8 -foot by 10 -foot) shed/building Flow metering equipment This drainage report describes the stormwater infrastructure that will be installed as part of the project, which includes the following (Appendix A): 0 Concrete -lined channels to manage on -site runoff • one detention basin with outlet structure N_OB18-1O17\Prairie Dog Drainage 2-18\Final_219.docx 1 Daniel B. Stephens & Associates, Inc, 3. Drainage Analysis As part of development, functionally all of the site will be covered with gravel. Per Weld County Engineering and Construction Criteria Manual (WCECCM) Table 5-3, the imperviousness of gravel areas is assumed to be 40 percent. The footprint of installed equipment and the building is relatively small, and is assumed to have a negligible impact on runoff. Therefore, the increase in percent impervious area on the site is 38 percent, from an assumed 2 percent in the agricultural condition (Table 5-3, WCECCM) ) to 40 percent of the total acreage. Given the nature of the development, this project is considered "urbanizing." For all analyses, the rainfall depths were taken from National Oceanic and Atmospheric Administration (NOAA) Atlas 14 for the site (Appendix B). There is a small drainage ditch along WOR 10 where stormwater from this site will be discharged. Per Weld County guidelines, the stormwater management pond is designed as an extended detention basin, as the contributing area is greater than 2 acres. 3.1 Pre••Deve!opmen f Conditions The site is approximately 2.5 acres zoned for agricultural use. Site drainage flows from east to west, where it continues onto adjacent agricultural property. Flow across the site is sheet flow, with no natural channels or manmade stormwater management facilities. The site is gently sloped, with an overall slope of around 4 percent. None of the site is designated as 100 -year floodplain. The National Flood Insurance Program has not published a flood hazard map for this area, as the entire local area has been determined to be without flood hazards (Appendix C). The site soils consist of various loamy sands (Appendix C O . The on -site soils fall into Hydrologic Group E, which have a moderate runoff potential. The regional topography around the site also has gentle slopes (around 2 to 4 percent). As discussed in Section 363, there is no run-on from adjacent properties. P:\ DB18-1011\Prairie Dog Drainage 2-16kFinal_2191docx 2 Daniel B. Stephens & Associates, Inc. 3.2 Post -Development Conditions Post -development, the site will have a single land use, covered with gravel. The entire site will be disturbed after construction. The entire site was analyzed as one watershed to size stormwater channels and detention ponds. The peak discharge for the area was determined using the UDFCD rational method calculation (Appendix E). The UDFCD detention calculation was used to size a detention basin to manage stormwater runoff from the site (Appendix E). Per LI DF+ D guidance, the UDFCD culvert calculation was used to size the discharge pipe from the basin. The basin's outlet structure has an orifice plate that restricts flows below the 100 -year storm to pre -development peak discharges and a restrictor plate on the discharge pipe that restricts the 100 -year storm to 90 percent of pre - development peak discharge (Appendix A). Stormwater conveyance channels were designed to convey flows to the detention basin. As this is an industrial site, per WCECCM Table 5-10, the stormwater channels were designed to convey the 10 -year storm. The site grade will split flow between the two channels naturally; for conservatism, each channel has been sized to convey the 10 -year storm for the entire site. To convey the water into the pond, the channels were flared at the transition to the pond. In this transition, the flow depth is reduced from 0.5 foot to o.2 foot, and the freeboard is reduced from 2 feet to 1 foot, Channel sizing calculations are included in Appendix E. Per WCECCM Table 5-9, analysis of flow depth, velocity, and Froude number were compared for two different Manning n values to assess channel capacity and stability in a variety of conditions. The channel design satisfies all applicable requirements for concrete -lined channels in erosion - resistant soils, This analysis was completed using the Manning equation in the computer software Bentley FlowMaster. All relevant assumptions and calculated flow characteristics are included in Appendix E, 3.3 Off -Site Drainage Routing Slopes in the area drain stormwater from the east to the west. The site's southern property boundary is WCR 10, which will intercept any flow from the south that might otherwise enter the site. On the site's northern property boundary, the topography drains to the west, not to the site. P:\DE116-1017\Prairie Dog arainege.2-181Final_219 deox 3 Daniel B. Stephens & Associates, .Inc The property on the eastern property boundary is developed and has stormwater infrastructure that routes stormwater to the roadside ditch on WCR 101 preventing it from entering the site. The result of property location, adjacent grades, and adjacent land use is that no off -site run-on needs to be managed. 4. Maintenance Stormwater infrastructure has been designed to be low maintenance to improve long4te rm performance. Maintenance, inspections, and repairs will be completed in accordance with the maintenance plan (Appendix F). Maintenance activities primarily consist of maintaining appropriate vegetation (through both revegetation and mowing), removal of sediment accumulation, and maintenance of the emergency spillway and discharge structure to keep them free of obstructions. 5a Conclusions In general, impacts from this development are anticipated to be minimal, as the detention basin reduces post -development flows to below pre -development flows for all storms below the 500 -year storm, and because stormwater will continue in the same roadside ditches in which it is currently conveyed.

Document Marne, Discovery Emergency Response Plan (DERP) to If Location; Section 2 — Incident Reporting and Management Purpose of Plan The purpose of this Discovery emergency response plan is to establish procedures and responsibilities to all foreseeable emergencies that may occur at Discovery Midstream DJ assets. An emergency is defined as any situation presenting a threat to human life, physical wellabeing, and company or personal property. The main objectives in any emergency response will be as follows (listed by order of importance): • Protection of personnel and the public • Protection of the environment • Compliance with federal, state, and local laws and regulations • Adhering to safety protocols • Restore normal operating conditions Discovery Midstream works to prevent emergency situations from occurring by implementing and adhering to a culture which values safety and by meeting and exceeding industry best safety practices, Examples include: • Use of all —steel pipe manufactured in the USA for Discovery oil and gas lines • Pipelines buried further underground than standard three (3) feet • Use of thicker, stronger, higher grade pipe than required by standard best practice • Adherence to strict welding standards and 100% -Ray of all welds • Integration of a rigorous pipeline integrity management program This plan is supported by the Discovery Midstream Lead hip team. The plan furnishes adequate emergency protection and provides training for the employees, contractors, and visitors at the facility. This plan applies to all employees, contract employees, guests and visitors to the facility during normal office hours, unless otherwise noted below: • Employees working outside normal hours will be responsible for carrying out the appropriate actions of this plan. Pre -Planning During pre -planning it is important to remember that no two emergency incidents are alike. Look at all the possibilities sunounding the emergency. This includes the size of the event, community and environmental impact, and the possibility of several types of emergencies which could occur at the same time.

Many of these process safeguards are critical equipment subject to regular testing and preventative maintenance as defined in facility mechanical integrity program. The safeguards prevent emergency conditions from occurring. The Discovery Midstream Gas Plant and compressor stations also have equipment and systems available for personnel to actively respond to an emergency condition. These include: �* Facility Emergency Shutdown System D) • Portable Fire Extinguishers placed at required intervals Fixed Gas Detectors with equipment shutdown. capabilities • First Aid Station • Portable Gas Detectors • Smoke Detectors in occupied buildings Discovery Midstream personnel are trained in the use of each to the extent required by authorities having jurisdiction and manufacturer's recommendations. Accountability of Person nel Facility operator wilt conduct accountability of personnel at muster areas utilizing facility sign -in sheet. Equipment Shutdown Operations Department will be responsible for shutting down procedures. Incident Communication - Radio Use Two (2)sway radios will be utilized as the primary communication devices in the event of an incident. Cellular (cell) phones will be utilized in the event radios are not transmitting/receiving communications. Location of Discovery Operation Center(DOC) The Discovery Operation Center is located at 4501 Weld County Road 35 Fort Lupton, CO 80621. Ideally, the Operations Center should be equipped with a radio base, several phone lines, and be centrally located for personnel to be dispatched from.

The Incident Notification Procedure assures an incident is promptly addressed at appropriate level to provide resources and support to control and mitigate incident. Implementation of a three tier system helps ensure notification of State and Federal agencies (as applicable), while enabling Discovery Midstream to evaluate impact of incident on employees, general public, and customers. In order to properly respond to any emergency, incidents should be classified into one of three levels. The incident level is determined by complexity of the incident, risks to company personnel and public, and impact on the environment. The three level classifications will be used and communicated to all personnel within the company. Irr Level I Incident The most serious and highest level incident. Level 1 incidents are usually on going and typically involve at least one of the following: a. Any fatality b. Event requires support of government or Emergency Responder agencies c, A non -incipient fire, rupture or explosion involving a Discovery Facility that requires assistance from Emergency Responders d. Any media attention at a Discovery Incident e. Results in more than $100,000 in estimated Property damage *A Level 1 Incident will automatically activate the Corporate Emergency Support Team and Emergency Operations Center. Notification Protocol: a. Immediately notify local Supervision, Discovery Operations Center (DOC), Director of Operations, COO b. Discovery Operations Center (DOC) will activate Discovery local First Responde (s) and local city/county fireiemergency organization if needed. c.

While most incidents are small enough that only limited incident command will be required, larger incidents may require a fall -scale ICS. The ICS is designed to enable effective and efficient incident management by: Integrating a combination of facilities, equipment, personnel, etc. within a common organizational structure • Enabling response measures to be scaled according to nature and size of incident • Involving only those functions required for level of response (i.e. operations, finance, public relations) • Allowing one person to take charge of incident for the company and determine size of response required Merging into and working with ICS of responding agencies (most governmental agencies use an ICS) Discovery ICS matrices for Level 1, Level 2, and Level 3 incidents are provided. The formats are for .ill -scale ICS, while normally only a portion of the ICS will be required. For Level 1 and Level 2 incidents, personnel will assume responsibility for primary duties in ICS. One person may assume various or all responsibilities for Level 3 incidents. The ICS structure is meant to be flexible. The Incident Comlnander is responsible for establishing the size and strength of the team.. Primary jobs are: • Incident Commander • Director of Operations (Incident Response Leader) • Operations Lead (Logistics — Calls contractors and field assistance) • Manager of Engineering (Planning — Decides on response strategies/schedules events) • chief Operating Officer (Executive Lead) • Finance Office (Receives invoices, approves and signs) • Media Relations Officer (Interacts with media, community, etc.) *Note — First on -scene employee is the incident commander until other employees or agency responders arrive with increased training and experience in handling type of incident.

Initial Response for an Unexplained Gas Loss: a. The initial response shall be to dispatch an operations employee to the site suspected to search the area for the source of the leaking gas. b. If there is difficulty locating a suspected leak, the following steps shall be implemented: i. Shut down the line in question under pressure and watch for a pressure drop. Close intermediate valves to isolate leaking section. ii. Look for signs of damage to vegetation, wilted leaves, etc. iii. Use a probe bar to make holes above the line, taking care not to hit the line itself, and sniff the holes with a leak detector. iv. Using detection equipment, inspect the open end of casing vents. v. Obtain more sensitive equipment to perform a flame -ionization survey. vi, If required, shut down and isolate the line into sections and determine which section is not holding pressure. See the Discover Pipeline tactical Plan for valve locations. I Action to be taken a. Determine if a 911 call is needed. If the leak is in the pipe itself, and is escaping from a small hole or pit, the leak may be stopped with a repair clamp. b. After this temporary repair has been made, the line should be permanently repaired when conditions are safe to do so. If corrosion is suspected, a survey of the irmnediate area should be made to check the effectiveness of the cathodic protection in the area. c. lithe leak is too large for a temporary repair, the system should be shut down, isolated from the stations, and the nearest isolation valves closed. The affected segment of line should then be blown down to atmospheric pressure and repairs made by qualified and approved personnel. 4. Returning to Service a. The amount of time required for purging will depend on the pressure used to page, the location of the repair along the line, and the amount of air allowed into the line during the repair procedure. As each incident may contain unique elements, a plan for returning to service will be prepared for each incident, in accordance with the Purging Procedures in the Discovery Midstream Pipeline System Operations and Maintenance Manual (reference Gas O&M 1501). b. After the line is back in operation, a thorough investigation of the cause of the leak shall be made and action taken to prevent a re -occurrence. This may entail sending a specimen of the pipe from the leak site to an independent laboratory for examination, if the teak was due to failure of the pipe, a weld failure, or corrosion. If the leak was caused by third ply damage, analysis may not be necessary. 5, The Pipeline Operator, employee team member, or authorized designee shall: a. Monitor line pressure at delivery and receipt points and station sites b. Open or close isolation valves as necessary to stop the supply of gas to the affected area. Page 23 of 43 I i I?
