Davis Chairman Cc: Cory Jordan Discovery Midstream Partners 7859 Walnut Hill Lane, Suite 335 I Dallas Texas 75230 214,414.1980 Di5C_UvOryM dslrearri.cOn) DISCOVERY USR QUESTIONNAIRE Planning Questions: 1. Explain, in detail, the proposed use of the property: The proposed use of this right-of-way (ROW) is a 20" natural gas pipeline and a 100' x 100' pipeline interconnect site with above ground piping, valves, and launchers and receivers that will accommodate in -line inspection and cleaning tools. This gas pipeline is approximately 17 miles long and runs from the intersection of Weld County Road (WCR) 49 south approximately 17 miles to the Milton -Hudson Interconnect Site at Highway 52. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan: Section 22-2-10(D) of the Weld County Code states that the "extraction of natural resources is an important part of the economy of the County." The proposed 20" 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(C2) 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 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 ROW adjacent to the road, and any roads will be bored under, rather than trenched across. The pipeline will comply with all federal, state, and local policies and legislation per Section 22-2-80(E). Section 22-5-90(C) states that, due to the over capacity of pipelines and refineries in the state, there is an increase in 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 support, service, and pipelines are acceptable as a Use by Special Review within the district. The meter site and above grade pipeline appurtenances shall be designed to comply with the requirements of Section 23-2-240 and operated per the requirements of Section 23-2-250. 4. Describe what type of land uses surround the site. Explain how the proposed use is consistent and compatible with surrounding land uses. The surrounding land usage for the site in question is primarily agriculture. The new pipeline will be routed within new and existing ROWs and will not interfere with agricultural production. The pipeline will be compliant with 49 CFR 192. DISCOVERY USR QUESTIONNAIRE 5. What are the hours and days of operation? The pipeline will be in operation for twenty-four (24) hours a day, seven (7) days a week. 6.

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 site. Include contractors, truck drivers, customers, volunteers, etc.: During construction, approximately forty (40) people will be employed along the ROW. During operation, there will be intermittent access to the ROW for maintenance activities by both Discovery DJ Services, LLC 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 on site. 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 ROW will be re -seeded after completion of the pipeline to return the area to original condition per ROW agreements. The interconnect site will be gravel and surrounded by a 7' tall chain link fence with Carlsbad Canyon tan slats. 11. How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed? : The pipeline will be routed below grade within the ROW and will not require parking. 12. Explain the existing and proposed landscaping for the site: The existing site is agricultural land. The pipeline will be cut and filled with the original grading surface. The ROW will be re -seeded after completion of the pipeline to return the area to original condition per ROW agreements. The interconnect site will be gravel and surrounded by a 7' tall chain link fence with Carlsbad Canyon tan slats. 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 interconnect site will have a 7 foot tall chain link fence with Carlsbad Canyon Tan slats. DISCOVERY USR QUESTIONNAIRE 14. Describe the proposed screening for all parking and outdoor storage areas: No screening will be implemented. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs: When the pipeline is decommissioned, Discovery DJ Services, LLC will run cleaning tools and nitrogen through the pipeline to purge it of any remaining fluids. The pipeline will be disconnected from the source of natural gas, sealed and capped, and permanently removed from service. This procedure will comply with all applicable laws and codes, including, but not limited to, 49 CFR 192. 16. Who will provide fire protection to the site? : Reference the attached Emergency Response Plan. 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: Upon completion of the pipeline installation, the surrounding environment will be restored per ROW 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. 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): During construction, there will be construction equipment and heavy machinery on site. The maximum number of anticipated passenger vehicles is 20 vehicles per day. The maximum number of anticipated semi -trucks is 4-5 trucks per day. After construction completion, there will be intermittent vehicle access for maintenance activities. It is not expected to be more than one passenger vehicle per day. 2. Describe the expected travel routes for the site traffic: This pipeline follows and will be accessed by road WRC 49. The pipeline will also be accessed by WCR 36, 34, 32, 22, 20, 18, and Highway 52, which run perpendicular to the pipeline. Reference the attached map for details (MLTN-N-AM-003). 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.): Access to the pipeline could come from any direction at any point on the ROW. DISCOVERY USR QUESTIONNAIRE 4. Describe the time of day that you expect the highest traffic volumes: The traffic volume will be minimal. 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 access will depend on the section of pipe, but in every case, the nearest county road will be taken to the ROW. 6.

Summary statement of the project, to include, when applicable: 1. The source, capacity, size, destination, and type of facilities, support structures, lines, etc., involved. The proposed system is a 20" natural gas pipeline, which will flow from the intersection of Weld County Road (WCR) 36 and Highway 49 to the Milton -Hudson Interconnect Site approximately % mile east of the Highway 52 and WCR 41 intersection at a rate of approximately 150 MMSCFD. The pipeline will be approximately 17 miles long. This pipeline will be constructed primarily within existing rights -of -way (ROWs) and will be routed along roads and property boundaries to minimize impact to agricultural lands and neighborhoods. The pipeline will exist below grade. However, it will have small intermittent above -grade appurtenance sites, such as valve sets, to ensure the safety of the public and environment, and maintainability of the pipeline. The Milton -Hudson Interconnect Site will be a 100' x 100' pipeline site with above ground piping, valves, and launchers and receivers that will accommodate in -line inspection and cleaning tools. 2. A detailed report shall be submitted which includes information on the following items. a. A description of the pipeline — Natural Gas. The proposed pipeline will be constructed for natural gas gathering, and will primarily follow existing ROWs. It will be a 20" pipeline running approximately 17 miles at an estimated daily average flowrate of 150 MMSCFD. To mitigate corrosion, the proposed pipeline will be coated with fusion bonded epoxy coating and an impressed current cathodic protection system will be installed. Launchers and receivers capable of accepting internal inspection tools will be installed. b. A description of the preferred route or site and reasons for its selection. See the attached map and route description for details. This pipeline follows and will be accessed by road WRC 49. The pipeline will also be accessed by WCR 36, 34, 32, 22, 20, 18, and Highway 52, which run perpendicular to the pipeline. Access to the pipeline could DISCOVERY USR Application Requirements, Sec. 23-2-510 come from any direction at any point on the ROW. This access is the more efficient way to approach the relevant segment of pipe and will create the least amount of disturbance. The size of the Milton -Hudson Interconnect Site is 100' by 100'. It is located at the intersection of the Milton West, Milton North, and Hudson 20" pipelines approximately 34 mile east of the Highway 52 and WCR 41 intersection. This is the most cost-effective and efficient route in which to install this pipe. In addition, the majority of this route follows existing ROWs. c. Procedures to be employed in mitigating any adverse impacts of the proposed routes or sites. Waste materials will be handled, stored, and disposed in a manner that controls blowing debris, and other potential nuisance conditions. Dust will be confined on the property as much as possible. Water trucks will be used to mitigate the dust in dry situations. Matting will be used in areas where equipment or trucks will sink and leave major impact to the ground. Please refer to the attached Storm Water Management Plan. 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 three months. The project will be continual and not be completed in phases. Construction will consist of ROW clearing, pipe layout, trenching, lowering, backfilling, hydrotesting and returning the ROW to its original condition. Roads, irrigation canals, and railroads will be crossed using the horizontal directional drill method. 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 and distributed to houses within 500 feet of the ROW. 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' below grade. 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: 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. DISCOVERY USR Application Requirements, Sec. 23-2-510 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. The pipeline will be remotely monitored at a control center 24 hours per day, seven days per week. 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. 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 the edges of the field where no irrigation will take place. All equipment and personnel will stay within the ROW at all times. All impacted ground will be reseeded and restored back to original grade per ROW 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 the "extraction of natural resources is an important part of the economy of the County." The proposed 20" 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(C2) 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 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 ROW adjacent to the road, and any roads will be bored under, rather than trenched across. The pipeline will comply with all federal, state, and local policies and legislation per Section 22-2-80(E). Section 22-5-90(C) states that, due to the over capacity of pipelines and refineries in the state, there is an increase in 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 DISCOVERY USR Application Requirements, Sec. 23-2-510 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 Midstream will run cleaning pigs, and then run nitrogen through the pipeline to purge it of any remaining fluids. The pipeline will be disconnected from the source of natural gas, sealed and capped, and permanently removed from service.

Page 7 of 43 Document #: 2.2 I Revision #: 11 [Revision Date: j 7/21/2017 Document Name: Discovery Emergency Response Plan {DERP) Location: Section 2 —Incident Reporting and Management Incident Command System Discovery Midstream follows an Incident Command System (ICS) structure when responding to any incident. While most incidents are small enough that only limited incident command will be required, larger incidents may require a full-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 full-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 Commander 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.

Upon completion of the repairs, the line shout be refilled at a rate that will ensure complete evacuation of any air within the line. The amount of time for purging will depend on the pressure used to purge, the location of the repair, and the amount or air allowed into the pipeline during repair. Purging shall be conducted in accordance with the Purging Procedures in the Discovery Midstream Gas Pipeline System Operations and Maintenance Manual.(Reference Gas O&M 1501) 6. Investigation a. Once the initial investigation criteria has been met, and the area has been approved to be returned to operation, a thorough investigation of the cause of the incident shall be made and action taken shall be reviewed to ensure the effectiveness and continuity of the plan. Changes deemed necessary should be implemented as quickly as possible. Pipeline Leak / Unexplained Gas Loss 1. Initial Response for a Pipeline Leak: a. The initial response to any leak in the pipeline shall be to dispatch the nearest Pipeline Operator, employee team member or authorized designee to the site reported and to search the area reported for the source of the leaking gas. Responders should be aware of wind direction and low lying areas where product may settle and the respective hazards of each. In no case, will any person approach an area exceeding 10% LEL. b. Once the source of the gas leak has been located, the area shall be kept clear of all personnel other than those of the Company or of a Contractor. Once the area is Page 22 of 43 Document #: 2.2 I Revision #: 11 I Revision Date: 7/21/2017 Document Name: Discovery Emergency Response Plan (DERP) Location: Section 2 — Incident Reporting and Management secured, the leak shall be stopped by suitable means (i.e., Shut down compressors or isolate the leak through the use of block valves). 2. 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. 3. 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 immediate area should be made to check the effectiveness of the cathodic protection in the area. c. If the 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 purge, 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 leak was due to failure of the pipe, a weld failure, or corrosion. If the leak was caused by third party 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 A.

This gas pipeline is approximately 17 miles long and runs from the intersection of Weld County Road (WCR) 49 and Weld County Road (WCR) 36 south approximately 17 miles to the Milton -Hudson Interconnect Site at Highway 52. This Traffic Narrative 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. The pipeline will be in operation for twenty-four (24) hours a day, seven (7) days a week. There will be no full time or part time employees on site. BACKGROUND The new pipeline will be routed within new and existing ROWs and will not interfere with agricultural production. The pipeline will be compliant with 49 CFR 192. This use is proposed and will not be constructed until the proposed Use by Special Review application is approved. Access to the site is located on WCR 34.5 via an existing access. The access point is gravel for several hundred feet and will be graveled the remaining distance to the site. WCR 34.5 is a gravel road. TRAVEL ROUTES/DISTRIBUTION Discovery's Laydown Yard is located in T2N, R64W, Section 23: W/2SW1/4. Traffic the will enter and exit the Laydown Yard from Weld County Road 18 and head East to Market Street, turning South onto the I- 76 entrance ramp heading West. Traffic will exit 1-76 onto Weld County Road 49 or HWY 52 exit at Hudson. See attached Haul Route Map. This pipeline follows and will be accessed by road WRC 49. The pipeline will also be accessed by WCR 36, 34, 32, 22, 20, 18, and Highway 52, which run perpendicular to the pipeline. See attached Haul Route Map. The access will depend on the section of pipe, but in every case, the nearest county road will be taken to the ROW. Access to the pipeline could come from any direction at any point on the ROW. Discovery proposes improvements to the existing access including graveling and sediment tracking. TRIP GENERATION/TIMING During operation, there will be intermittent access to the ROW for maintenance activities by both Discovery DJ Services, LLC employees and third party contractors. The traffic volume will be minimal. The traffic that does occur will be within daylight hours (7 a.m. to 7 p.m.). Page 1 of 2 CONSTRUCTION TRAFFIC During construction, there will be construction equipment and heavy machinery on site. The maximum number of anticipated passenger vehicles is 20 vehicles per day. The maximum number of anticipated semi -trucks is 4-5 trucks per day. After construction completion, there will be intermittent vehicle access for maintenance activities. It is not expected to be more than one passenger vehicle per day.

The resource review considered a 400 -foot -wide corridor centered on the pipeline for potential direct project effects, and a 1 -mile -wide corridor for potential indirect project effects. Discovery DJ Services, LLC, provided the centerline via KMZ file format. As a part of this desktop review, a limited field reconnaissance was conducted in proximity to wetland and waterbody crossings. No other field surveys were completed. The purpose of this review is to identify any significant cultural resource constraints associated with the development of the pipeline. Three historic canals (Beebe Seep Canal, Bowles Seep Canal, and the Speer Canal) and six potentially historic roads (Weld County Road 12, Weld County Road 35, Weld County Road 37, Weld County Road 41, Bowles Canal Road, and State Highway 52) are the only cultural resources identified in this desktop review that may be adversely affected by this project. SWCA Environmental Consultants recommends boring the pipeline below these resources to avoid physical damage to the resources. No areas within the review area possess a high potential of containing previously undocumented buried archaeological deposits. iii SWCA Desktop Cultural Resource Review Proposed Milton West Pipeline Weld County, Colorado This page intentionally left blank. iv SWCA Desktop Cultural Resource Review Proposed Milton West Pipeline Weld County, Colorado INTRODUCTION Discovery DJ Services, LLC, contracted SWCA Environmental Consultants (SWCA) to complete a cultural resource review for 5.97 linear miles of proposed pipeline west of Hudson, Weld County, Colorado (the Milton West pipeline) (Figure 1). The resource review considered a 400 -foot -wide corridor centered on the pipeline for potential direct project effects, and a 1 - mile -wide corridor for potential indirect project effects. SWCA conducted a review of cultural resource records for the pipeline, including a file search through the Colorado Office of Archaeology and Historic Preservation (OAHP) COMPASS database on September 13, 2017. This review was performed to evaluate the nature of the historical occupation of the area and to assess the potential for previously unrecorded cultural resources. Additionally, SWCA reviewed General Land Office (GLO) maps, maps from the U.S. Geological Survey (USGS) U.S. Topo and Historical Topographic Map Collection, and aerial imagery. 1 SWCA Desktop Cultural Resource Review Proposed Milton West Pipeline Weld County, Colorado Figure 1* Overview of the proposed Milton West pipeline. 2 SWCA Desktop Cultural Resource Review Proposed Milton West Pipeline Weld County, Colorado OAHP FILE SEARCH RESULTS The OAHP geographic information systems (GIS) records search identified eight previous cultural resource inventories that have been conducted within 1 mile of the project centerline, two of which are within 200 feet of the proposed pipeline centerline. One of these previous inventories was conducted for the Front Range Pipeline project, and the other was conducted for a fiber optic line build (Table 1). Table 1. Previous Cultural Resource Inventories within 200 Feet of Proposed Centerline Survey ID Name _ Institution Authorship MC.AE.R26 A Class III Cultural and Class I Atkins North Shipp, Julie, Brandy Paleontological Resources Survey of Spread 1 of the Front Range America Harris, Collin Rucker, and Robert Pipeline Project (and Addendum Rowe A), Weld, Adams, Arapahoe, Elbert, and El Paso Counties, Colorado MC.CH.R88 An Archaeological Inventory of the Enron Communications Centennial Archaeology Neidhardt, Peter M., and Jason Marmor Wyoming/Colorado Border to Denver Segment, Wasatch Reach Fiber Build, Northern Colorado The OAHP file search results identified eight previously recorded sites or site segments within 1 mile of the proposed centerline. Only one site, a historic corral, water pump, and windmill that has been determined not eligible for the National Register of Historic Places (NRHP) (5WL7296), was mapped in the OAHP records within 200 feet of the proposed centerline. Of the seven other sites between 200 feet and 1 mile from the proposed centerline, none are determined or recommended to be eligible for NRHP nomination. SWCA therefore recommends that none of the cultural resources identified in the OAHP file search results within 1 mile of the proposed centerline will be adversely affected by the project, and no further work is recommended for these resources. HISTORIC PROPERTY REVIEW In an attempt to identify significant historic properties not present in the OAHP records, SWCA reviewed historic maps of the project area, including the 1863 GLO plat for Township (T) 1 North (N), Range (R) 66 West (W), the 1867 GLO plat for T1N, R65W, and the 1869 plat for the Denver Pacific Railway (Bureau of Land Management 2016). Historic topographic maps containing information mapped between 1949 and 1971 were also reviewed. The GLO plats depict no features of potential significance. Many of the first roads in the region tended to follow property lines and the section lines surveyed by the GLO (Autobee and Dobson -Brown 2003:E-52). In 1885, the Colorado General 3 SWCA Desktop Cultural Resource Review Proposed Milton West Pipeline Weld County, Colorado Assembly passed legislation that allowed county commissioners to declare any section or township line on the public domain a public highway. Six potentially historic named roads —Weld County Road 12, Weld County Road 35, Weld County Road 37, Weld County Road 41, Bowles Canal Road, and State Highway 52 —have been mapped in proximity to the proposed centerline (U.S. Census Bureau, Geography Division 2016). Five of the six roads have been upgraded and/or paved; all remain in use today. Based on the historic topographic maps, Bowles Canal Road appears to have originally functioned as a service road for the Bowles Seep Canal (5WL4843), but this road does not appear to have been formally recorded. To avoid adverse effects to any of these potentially historically significant roads, SWCA recommends avoidance by boring the pipeline under these roads. Given the amount of modem infrastructure in the immediate vicinity, indirect adverse effects caused by pipeline construction on either side of these roads are unlikely. Several buildings and canals are mapped on the historic topographic maps within the project vicinity (USGS and Esri 1949a, 1949b, 1950, 1951, 1969, 1971). The canals are still intact and include segments that have yet to be formally recorded and are therefore not contained in the OAHP files. Where these corresponded with potential U.S. Army Corps of Engineers jurisdictional waters of the United States, field reconnaissance was performed and the canals/ditches were recorded accordingly (discussed below). By 1949, several farmsteads had occupied the project vicinity (USGS and Esri 1949a, 1949b, 1950, 1951), and these are represented by mapped buildings on the historic topographic maps. The number of mapped buildings remains consistent without substantial increase through 1971 (USGS and Esri 1969, 1971). Undocumented historic farm complexes can best be understood within the context of the Historic Farms and Ranches of Weld County multiple property listing (Whitacre and Simmons 1990). The historic buildings cannot be entirely confirmed to be extant, but OAHP records for the few that have been formally documented indicate that farmsteads primarily not eligible for the NRHP are present in the vicinity. Considering the current level of modem visual disturbance in the area, the proposed pipeline is unlikely to result in significant indirect adverse effects to any NRHP-eligible historic buildings in the vicinity of the project. Aside from the ditch segments and scattered historic buildings, the historic map review identified one north -trending transmission line west of the project and several unnamed, unimproved roads on the 1949 topographic map (USGS and Esri 1949a). No other potential historic resources were identified in the project area vicinity that are not already identified in the OAHP records. The land patent search of the eight sections crossed by the proposed pipeline identified three that were patented by the Union Pacific Railway Company and one that was patented by the Denver Pacific Railway and Telephone Line/Union Pacific Railroad under the Union and Central Railroad Grant of 1862. Portions of four sections were patented under the Sale -Cash Entry Act of 1820 and the Homestead Act of 1862. 4 SWCA Desktop Cultural Resource Review Proposed Milton West Pipeline Weld County, Colorado FIELD RECONNAISSANCE Three ditch/canal segments were newly recorded for the current project: the Bebee Seep Canal (5WL2753.12), the Bowles Seep Canal (5WL4843.5), and the Speer Canal (5WL1485,23). The Beebe Seep Canal segment (5WL2753.12) was recorded between Weld County Road 12 on the south, and Colorado State Highway 52 on the north. This segment is approximately 0.5 mile long. The Beebe Seep Canal is a significant part of the historically complex Standley Irrigation System from 1909-1910 crossing Adams and Weld Counties. Given this association with early agriculture, the canal is eligible for NRHP nomination, and this segment contributes to this eligibility. The canal segment is located outside of the proposed project -related disturbance, but at its closest is approximately 15 feet from proposed disturbance. SWCA recommends avoidance of project -related disturbances by maintaining an avoidance buffer of at least 50 feet from this historic canal segment. If this avoidance buffer cannot be maintained, SWCA recommends fencing of the historic canal segment to limit disturbance to the resource. The segment is located adjacent to a two -track road, pasture, and cultivated and formerly cultivated fields, and the disturbance associated with pipeline construction will be temporary and will not result in indirect effects to this historic canal segment. The Bowles Seep Canal segment (5WL4843.5) was recorded through a pasture in Sections 6 and 7, T1N, R65W. The segment extends from approximately 200 feet north of Weld County Road 12 to 200 feet south of Weld County Road 12 for a distance of approximately 400 feet. The Bowles Seep Canal is the western bifurcation of the Beebe Seep Canal (Neely et al. 2004; Wilson et al. 2007), and as such is eligible for NRHP nomination due to its significant association with early agriculture in the region, including the aforementioned Standley Irrigation System; the newly recorded segment is intact and contributes to this eligibility. SWCA recommends avoidance of project -related disturbances by boring to place the pipeline at a sufficient depth under this canal. The segment is located in a pasture and passes underneath Weld County Road 12, and the disturbance associated with pipeline construction will be temporary and will not result in indirect effects to this historic canal segment. The Speer Canal segment (5WL1485.23) was also recorded through pasture and a fallow field in Sections 11 and 12, TIN, R66W. The segment extends for approximately 0.35 mile and is bounded by a material yard to the west-southwest and the edge of the survey corridor to the east-northeast. The Speer Canal was originally constructed in 1889 by the Hudson Ditch and Reservoir Company as the Western Hudson Lateral, but was later renamed the Speer Canal and became a significant part of the historically complex Standley Irrigation System from 1909- 1910 crossing Adams and Weld Counties (Driver and Kerns 2015). Given this association with early agriculture, the canal is eligible for NRHP nomination, and this segment contributes to this eligibility. SWCA recommends avoidance of project -related disturbances by boring to place the pipeline at a sufficient depth under this canal. The segment is located in a pasture and adjacent to a heavily disturbed materials yard and ranching complex, and the disturbance associated with pipeline construction will be temporary and will not result in indirect effects to this historic canal segment. 5 SWCA Desktop Cultural Resource Review Proposed Milton West Pipeline Weld County, Colorado GEOLOGIC FACTORS AFFECTING SITE POTENTIAL The project area is located in an area of predominantly low relief. Alfisols, Aridisols, and Entisols are the most common soil orders across the project area, but Mollisols are also represented along the far north -trending eastern end of the project area (Esri and Natural Resources Conservation Service 2014). The upland plains, which are characteristic of the eastern half of the project area and contain predominantly Alfisols and Aridisols, are prime farmland when irrigated (Esri and Natural Resources Conservation Service 2014), and the major factor affecting the preservation of buried archaeological material is the agricultural and urban development in the area. The western two-thirds of the project area contain predominantly Entisols that have weathered from underlying Cretaceous- and Tertiary -aged sedimentary rocks (Tweto 1979) and are unsuitable farm land. As a result, much of this area appears to remain uncultivated, with oil and gas wells and associated pipelines and roads being the major disturbance through this area. In the cultivated uplands, a mantle of soil may have buried archaeological deposits, but cultivation has disturbed the upper soil horizons. The intact Entisols in the western project area are likely not sufficiently stable to have encased significant cultural deposits. Depositional settings favorable to the preservation of buried archaeological material are also commonly associated with floodplains and terraces, however the proposed centerline does not cross major drainages associated with such deposits. Given this depositional setting and extensive cultivation, the project area is interpreted as having a low potential to contain significant buried archaeological deposits. SUMMARY AND RECOMMENDATIONS Three historic canal segments (Beebe Seep Canal, Bowles Seep Canal, and the Speer Canal) and six potentially historic roads (Weld County Road 12, Weld County Road 35, Weld County Road 37, Weld County Road 41, Bowles Canal Road, and State Highway 52) are the only cultural resources identified in this desktop review that may be adversely affected by this project. Although these resources are located in their historical agricultural setting with limited residential and oil and gas developments, the proposed Milton West pipeline alignment largely follows section lines and roadways with existing disturbance. As a result, the visual settings of these historic resources are unlikely to be compromised by the proposed pipeline, especially once the pipeline corridor has been revegetated. SWCA recommends using boring to avoid physical damage to the majority of these resources, and avoidance within 50 feet and/or fencing of the Beebe Seep Canal at the eastern end of the project area. By adhering to these avoidance measures, construction and operation of the Milton West pipeline should result in no adverse effects to significant known historic properties. No areas within the review area possess a high potential of containing previously undocumented buried archaeological deposits. However, in the event that such a discovery is made, SWCA recommends that the resource be formally recorded and evaluated for NRHP eligibility by a permitted archaeologist. 6 SWCA Desktop Cultural Resource Review Proposed Milton West Pipeline Weld County, Colorado REFERENCES CITED Autobee, Robert, and Deborah Dobson -Brown 2003 Colorado State Roads and Highways Multiple Property Listing.

SWCA conducted the wetland delineation and species evaluation within a 200 -foot -wide survey corridor around the proposed centerline. The wetland delineation includes the identification and recording of physical features that may be considered waters of the U.S. as defined by the U.S. Army Corps of Engineers (USACE). Waters of the U.S. include most rivers, creeks, streams, lakes, and their associated special aquatic sites. Special aquatic sites include sanctuaries, refuges, wetlands, mud flats, vegetated shallows, coral reefs, and riffle and pool complexes. When applying for a Clean Water Act permit, the USACE requires special aquatic sites to be addressed separately from other waters of the U.S., if they are present. Wetlands are the most common special aquatic site and are defined by the USACE as "areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" (USACE 1987). For an area to be considered a wetland, it must support the following under normal circumstances: 1) the presence of hydrology showing regular inundation; 2) a predominance of hydrophytic (adapted to moist or saturated soils) vegetation; and 3) soils characteristic of frequent saturation (i.e., hydric soils) (USACE 1987, 2010). 2.0 PROJECT DESCRIPTION The West Milton pipeline is approximately 5.0 miles in length, with the west terminus located 4.2 miles east of Fort Lupton and the east terminus located 1.4 miles west of Hudson, Colorado (see Figure 1 in Appendix A). The land use along the pipeline is predominantly agriculture and pasture. The project also crosses herbaceous native upland grassland generally in poor condition due to anthropogenic disturbances. Pipeline trenching activities will be completed using standard construction practices. The trench will be positioned to one side of the construction right-of-way (ROW) to allow for spoil to be placed opposite of the wider working side. The 80 -foot -wide construction ROW is composed of a 50 -foot -wide permanent easement and a 30 -foot -wide temporary construction easement. All water features will be bored, thereby avoiding any impacts to waters of the U.S. No permanent loss of wetlands or waters will occur as a result of constructing the pipeline. 3.0 METHODS The methods described herein were implemented in the pre -fieldwork desktop review and field surveys, and in the reporting of the results and production of all maps and information contained in Section 4.0 and Appendix A, respectively. 3 SWCA Biological Resources Report West Milton Pipeline Weld County, Colorado 3.1 PRE -FIELD SURVEY Prior to field surveys, SWCA performed a desktop analysis to review baseline data for biological resources in the project area, including U.S. Geological Survey (USGS) topographic quadrangles, National Wetlands Inventory (NWI) data, USGS National Hydrography Dataset (NHD), Colorado Parks and Wildlife/Colorado Oil and Gas Conservation Commission wildlife maps, and recent aerial imagery provided on Google Earth. SWCA also conducted a desktop review for federally listed species and their critical habitats, if designated, in the project area. 3.2 FIELD SURVEY An SWCA biologist conducted the field surveys in September 2017. The biologist performed a pedestrian survey of a 200 -foot -wide corridor centered on the proposed pipeline. This survey corridor, wider than the 80 -foot construction ROW, will allow slight adjustments to the centerline without necessitating new surveys. Nevertheless, adjustments to the centerline alignment occurring subsequent to the original field effort that might extend beyond the original survey corridor would be subject to repeated field surveys. The surveys focused on waters of the U.S. including, but not limited to, wetlands, ditches, and streams, as well as federally protected plants and wildlife and their habitats. The biologist used a hand-held TrimbleTM global positioning system (GPS) unit that was loaded with the project centerline, 200 -foot -wide survey limits, roads, NHD lines, NWI polygons, and ownership layers to ensure accurate survey and mapping of the project area. Photographs were taken of all recorded features and are presented in Appendix B. 3.2.1 Wetlands The presence/absence of wetlands was evaluated in the field using routine delineation methods described in the U.S. Army Corps of Engineers Wetlands Delineation Manual (USACE 1987), and in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Great Plains Region (Version 2.0) (USACE 2010), hereinafter referred to as the Regional Supplement. Wetlands are characterized by a predominance of hydrophytic vegetation, presence of hydric soils, and presence of wetland hydrology. While surveying the alignment, the biologist scanned the survey corridor for visual evidence of changes in vegetation composition consistent with prolonged inundation or saturation, and changes in surface features indicating the presence of wetland hydrology. If any of these circumstances were present, the biologist recorded data necessary to complete a Regional Supplement Wetland Determination Data Form, providing documentation of the presence or absence of wetlands. Determination of wetland habitat type, if present, was based on the classification system developed by Cowardin et al. (1979). Wetland boundaries, if observed, were recorded at the upland/wetland interface on the GPS unit. 3.2.1.1 Vegetation The predominance of hydrophytic vegetation for each wetland plot was determined in the field by estimating the percent cover of the species present and assigning the appropriate wetland indicator status, as listed in the National Wetland Plant List (Lichvar et al. 2014). Hydrophytic 4 SWCA Biological Resources Report West Milton Pipeline Weld County, Colorado and non-hydrophytic (or upland) plant species were differentiated by their respective indicator status, such as facultative (FAC), facultative wetland (FACW), obligate (OBL), facultative upland (FACU), and upland (UPL). A plant community with greater than 50% dominant hydrophytes (FAC or wetter) was determined to meet the USACE criteria of a hydrophytic community. 3.2.1.2 Soils Hydric soil determinations were made according to criteria listed in the Regional Supplement and Field Indicators of Hydric Soils in the United States: A Guide for Identifying and Delineating Hydric Soils, Version 7.0 (U. S. Department of Agriculture, Natural Resources Conservation Service 2010). Where possible, soil pits were excavated to a depth of up to 20 inches, and the soil profile was then described by horizon. Each horizon was evaluated for soil color; thickness; the color, abundance, and contrast of redoximorphic features; soil texture; and comparison to mapped soils. Munsell soil color charts were used to determine the color of the soil matrix and redoximorphic features (Munsell Color 2009). The soil profile was studied for hydric soil indicators listed in the Regional Supplement. If the soil profile displayed one or more hydric soil indicators, a positive hydric soil determination was made. 3.2.1.3 Hydrology Wetland hydrology was determined in the field by considering frequency and duration of inundation, visual observation of saturation in the upper 12 inches of the soil profile, and the presence of other primary wetland hydrology indicators, such as oxidized root channels, water - stained leaves, water marks, sediment deposits, or algal matting. Secondary indicators used to determine wetland hydrology included surface soil cracks, drift deposits, drainage patterns, saturation signatures on aerial photographs, or the FAC-Neutral test. If the area displayed one or more primary hydrology indicators or two or more secondary hydrology indicators, a positive hydrology determination was made. 3.2.2 Waterbodies The presence/absence of lotie systems (e.g., creeks, rivers, arroyos, human -made ditches; collectively "streams") was identified in the field pursuant to guidance provided in the USACE Regulatory Guidance Letter No. 08-02 regarding ordinary high water mark (OHWM) identification (USACE 2005). An OHWM is a line on a shore established by fluctuations of water and indicated by physical characteristics such as a clear, natural line impressed on the bank; shelving; changes in the character of the soil; destruction of terrestrial vegetation; the presence of litter and debris; or other appropriate means that consider the characteristics of the surrounding areas. The OHWM is the defining element for identifying the lateral limits of non - wetland waters. Federal jurisdiction over a non -wetland water of the U.S. typically extends to the OHWM. All waterbodies were recorded on a Trimble GPS unit and photographs were taken at each site. 3,2.3 Sensitive Species and Wildlife Habitats SWCA reviewed the list of federally listed species for Weld County, Colorado, available through the U.S. Fish and Wildlife Service (USFWS) website (USFWS 2017) to determine the species that are evaluated in this report. In total, 10 species are listed for the project area (Table 5 SWCA Biological Resources Report West Milton Pipeline Weld County, Colorado 1). The USFWS also provides protection to avian species under the Migratory Bird Treaty Act (MBTA). The META makes it illegal for anyone to take, possess, import, export, transport, sell, purchase, barter, or offer for sale, any migratory bird, or the parts, nests, or eggs of such a bird, except under the terms of a valid permit issued by the USFWS. Several avian species protected by the MBTA, including raptors, are likely to occur within the project area. Table 1.

Source: USFWS 2017. * FE = federally listed as endangered; FT = federally listed as threatened SWCA reviewed color aerial imagery of the project area and performed a desktop analysis of potential federally listed species that might be present in the vicinity of the project area. SWCA also conducted qualitative comparisons of the habitat requirements of listed species with vegetation communities or landscape features observed in the project area during the field surveys. When an area met the habitat requirements of a listed species, that area was mapped in a geographic information system (GIS) format using a handheld GPS unit (Trimble). The Colorado -listed (Colorado Parks and Wildlife 2017) threatened western burrowing owl (Athene cunicularia) nests in prairie dog (Cynonays sp.) colonies in northeast Colorado. All prairie dog colonies located within the survey corridor were recorded and mapped during the field surveys. 3.2.4 Noxious Weeds Plant species listed on the Colorado Department of Agriculture's noxious weed list were surveyed for in the field. A complete inventory of weed occurrences allows for proper planning to control the spread of weeds in the project area. In the case that a noxious weed occurrence was identified in the field, a GPS location or boundary, field notes, and photographs were recorded to document this location. 3.3 FIELD MAPPING The spatial extent of features was recorded in the field using Trimble GPS units with sub -meter accuracy. Coordinates of vertices were recorded along the perimeter of each wetland and other potential waters of the U.S. Field data were processed using ArcMap 10.5 software. The acreage of wetlands and other waters of the U.S. overlapping the survey corridor and construction ROW was determined by calculating the area where the project footprint and any delineated features overlap. 4.0 RESULTS 4.1 WETLANDS No wetlands are located within the survey corridor. 8 SWCA Biological Resources Report West Milton Pipeline Weld County, Colorado 4.2 WATERBODIES The project crosses three named, earthen ditches; the Speer Canal, Bowles Seep Canal, and Beebe Seep Canal were delineated within the survey corridor. Additionally, an excavated pond was delineated within the survey corridor. The pond has a hydrologic nexus with the Speer Canal via additional excavated ponds to the north. The general characteristics and OHWMs of each waterbody were recorded and are summarized in Table 2. The locations of these features are illustrated in Figure 2 in Appendix A and a photograph of each surveyed waterbody is provided in Appendix B. Table 2.

No designated critical habitats for endangered species are present in the project area and therefore the project will likely result in "no effect" to federally listed species (USFWS 2017). Two raptor nests were identified with 0.5 mile of the survey corridor during field surveys. The two nests identified are summarized in Table 3 and their locations are illustrated in Figure 2 in Appendix A. Table 3. Raptor Nests Identified within 0.50 -mile Survey Corridor Feature ID Nest Status at Time of Survey Raptor Species Distance from Centerline (feet) _ _ _ Nest Description and Location R1AWE059 Inactive Potential red- tailed hawk (Buteo jamaicensis) 290 Stick nest in cottonwood (Populus deltoides) tree with red-tailed hawk perched in tree. R1AWE060 Inactive Potential red- tailed hawk 114 Stick nest in cottonwood tree with red-tailed hawk perched in tree. Both nests appeared to be occupied by red-tailed hawks (Buteo janaaicensis), although no chicks were observed and would be expected to have fledged the nest at the time the survey was 9 SWCA Biological Resources Report West Milton Pipeline Weld County, Colorado performed. Colorado Parks and Wildlife guidelines recommend no surface occupancy (above ground, permanent structures) within 0.3 mile of an active red-tailed hawk nest at any time and no human encroachment of an active red-tailed hawk nest within 0.3 mile from February 15 through July 15 (Colorado Parks and Wildlife 2008). If construction activities are planned between February 15 and July 31, follow-up surveys to confirm nest status are recommended for these identified nests. If construction activities are to occur while raptors are actively nesting, SWCA recommends additional mitigation measures such as nest monitoring or consultation with Colorado Parks and Wildlife. Migratory bird nesting (non -raptor) generally starts in northern Colorado on or shortly after April 1 of each year. The MBTA prohibits the take or destruction of all nests. Other federally protected migratory bird species may nest in the project area, so any ground disturbance activities commencing after April 1 should be preceded by nesting bird surveys to ensure compliance with the MBTA. One prairie dog colony, approximately 13 acres in size, is located partially within the survey corridor and has the potential to support nesting burrowing owls. Colorado Parks and Wildlife (2017) guidelines recommend burrowing owl protocol surveys to confirm the presence or absence of nesting burrowing owls to avoid inadvertent take (i.e., disturbance, harassment, mortality) if construction is scheduled to occur between March 15 and October 31. If nesting burrowing owls are observed, consultation with Colorado Parks and Wildlife should occur to determine any necessary protection measures. The colony is identified as PD1AWE055 in Figure 2 in Appendix A. 4.4 NOXIOUS WEEDS One noxious weed occurrence, spotted knapweed (Centaurea stoebe) (N1AWE013) is located within the survey area. The infestation is approximately 20 plants within a 0.25 -acre area and its location is illustrated in Figure 2 in Appendix A. The species is considered a Colorado List B noxious weed (Colorado Department of Agriculture 2017), required by state law to be suppressed where found. 5.0 SUMMARY Within the survey corridor, three named canals and one excavated pond were identified. The pipeline will be installed via horizontal bore technique under all water features. Two raptor nests and one prairie dog colony were also located and documented during the field survey. The identification of water features within the project area supporting OHWMs does not necessarily indicate that these features are subject to Clean Water Act Section 404 jurisdiction. SWCA biologists believe these features may have downstream connectivity which means they are likely jurisdictional, however only the USACE can make determinations regarding the status of waters of the U.S. For the purposes of this project, Discovery DJ Services assumes that each of these features is subject to USACE jurisdiction and proposes to either avoid impacts or to adhere to all terms and conditions of Nationwide Permit 12 for utility lines when working within or adjacent to these features. 10 SWCA Biological Resources Report West Milton Pipeline Weld County, Colorado 6.0 REFERENCES Colorado Department of Agriculture. 2017.
