Lupton Pipeline Project in Weld County, Colorado Dear Ms. Diedrich, The purpose of this letter is to describe the results of a Class I Cultural Resource Site File Search and Literature Review for the Lancaster to Ft. Lupton Pipeline Project (Project), in Weld County, Colorado. The results of this review include previously recorded sites and previously conducted surveys within 1 -mile of the Project's area of potential effect (APE). For the purposes of this review, the term "APE" refers to a 300 -foot wide buffer (150 -foot wide each side of the centerline) around the approximately 4.1 -mile -long primary pipeline corridor (Figure 1). The site file search covered a 2 -mile -wide buffer (1 -mile each side) around the Project centerline and this area is referred to as the "Research Area." The Project Research Area is located within the Platteville (1969), Milton Reservoir (1971), Hudson (1988) and Fort Lupton (1988) quadrangles. The legal locations of the Project Research Area listed below in Table 1. Table 1. Legal Locations of the Lancaster to Ft. Lupton Pipeline Project Class I Research Areal. Township Range Section 2 North 66 West 10-15, 22-28, 33-36 1 North 66 West 1-3 1. Sixth Principal Meridian, Weld County, Colorado Tetra Tech, Inc. (Tetra Tech) conducted the site file search through the Colorado Historic Society Office of Archaeology and Historical Preservation (OAHP) Colorado Cultural Resource On-line Database (Compass) on January 16, 2017. This database includes records of all archaeological investigations that have been conducted and all cultural resources (prehistoric and historic archaeological sites) that have been previously recorded within the 2 -mile -wide Research Area. Included in the Compass data are records of properties listed on the National Register of Historic Places (NRHP). Tetra Tech also reviewed historic Bureau of Land Management (BLM) General Land Office (GLO) records and the Glenn R. Scott and Carol Rein Shwayder Historic Trail Map of the Greeley 1° x 2° Quadrangle, Colorado and Wyoming (1993) to determine whether vestiges Tetra Tech, Inc. 350 Indiana Street, Suite 500, Golden, CO 80401 Tel 303.217.5700 Fax 303.980.3539 www.tetratech.com Lancaster to Ft. Lupton Pipeline Project Page 2 of trails, transportation routes, homesteads, or other historic resources may be present in the 2 - mile -wide Research Area. The Compass website shows that 21 prior investigations have been undertaken in the Research Area and 23 cultural resources have been previously recorded. The previous investigations consist of Class III surveys for water conveyance systems, pipelines, water meter stations, public works facilities, and residential subdivisions (Table 2). The previously recorded resources consist of 12 sites and 11 isolated finds (IFs). Of the 12 sites, 11 are historic and one is prehistoric. The historic sites consist of seven ditch segments (5WL.2182.2, 5WL.2182.3, 5WL.2182.7, 5WL.1485.7, 5WL.1485.15, 5WL.1485.17, and 5WL.7225) two trash dumps (5WL.2212 and 5WL.2214), one homestead (5WL.7323) and one water control feature (5WL.3979). The one prehistoric site (5WL.195) consists of an open lithic scatter (Table 3). Of the 11 IFs, five are historic, five are prehistoric, and one is multicomponent (historic and prehistoric). Of the 12 sites, one has been determined as Eligible -Officially (5WL.1485.17), one is recommended as Eligible -Field (5WL.1485.7), one is recommended as Not Eligible -Field (5WL.3979), one is recommended as Not Eligible -Field within an Existing District (5WL.1485.15), one has not been assessed for NRHP eligibility (5WL.195), and the remaining seven sites have been determined Not Eligible -Officially (Table 3). None of the IFs are eligible for the NRHP. Sites 5WL.1485.17, 5WL.1485.7, and 5WL.195 should be avoided during the construction of the pipeline. If the Project footprint remains the same, none of these sites will be impacted since they are currently outside of the APE.

If the Project crosses any Colorado State owned lands or US Army Corps of Engineer's managed wetlands, Tetra Tech recommends a pedestrian cultural resource survey be conducted to determine if cultural resources are present in the APE. Sites that are recommended as Eligible (field or officially), or have not been assessed for NRHP eligibility, should be treated as Eligible resources and avoided during all ground disturbing activities. The sites and IFs that are not eligible -officially or not eligible -field do not require additional management If you have any additional questions, please feel free to contact me.

This Project is needed to meet the increased demand for natural gas services as a result of the recent population growth and urban development. This Project would reinforce the natural gas system infrastructure and provide safe, reliable service to PSCo's current and future customers in the region. As part of Xcel Energy's commitment to informing the community about the Project, the Project team held a public open house to provide stakeholders with information regarding the Project. Public Meeting Summary The meeting was held on Thurs., Jan. 26, 2017, from 5-8 p.m. and took place at the Fort Lupton Public and School Library at 425 South Denver Avenue, Fort Lupton, CO 80621. The open house included a Project overview, the Project purpose and need, Project maps, and the opportunity to provide the Project team with verbal and written comments. The meeting had an open -house format, which allowed for attendees to be greeted by a team member and be directed to specific areas of interest. This also allowed for the Project's stakeholders to connect with the Project team members at their convenience and arrive between 5-8 p.m. and not miss a formal presentation. Five display boards were posted in the meeting area to provide information about Xcel Energy and the proposed Project. The board titles are listed below and are included as Appendix D: • Welcome board • Project Overview, including information on the following: o Purpose and Need o Permitting Overview o Construction Overview o Project Schedule • Project Routing • Natural Gas Pipeline Safety • Project Overview Map —listing preferred and alternative routes Questions received during the public open house were logged and documented. The questions are captured within this report. Comment forms were provided to attendees, but no comment forms were filled out and returned to Project team members during or following the public open house. 1 Lancaster to Fort Lupton Natural Gas Pipeline Project Open House Meeting Summary Report Notifications A total of 51 property owners within 500 feet of the preferred and alternative alignment pipeline route centerlines (see Appendix A), were mailed notifications about the Project open houses via standard first class mail on Jan. 13, 2017. Additionally, a total of five government officials were included in the mailing. Government officials invited to the public open house are captured within Table 1.

Written comments cards were provided; however, no written comments were received during or after the public meeting. Verbal questions asked by meeting attendees are included below. Verbal Questions and Answers Who was invited to the meeting, and what was the notification area? All property owners within 500 feet of the centerline of the preferred and alternative pipeline routes were invited to the Project public open house. Additionally, Weld County and Fort Lupton officials were mailed notifications to attend the public open house. What stage of the process (timeline) are we in? Public Service Company of Colorado (PSCo), a Colorado corporation, doing business as Xcel Energy, is currently evaluating Project routing and working on initial permitting application submittals to Weld County. For current Project status, we encourage all interested parties to visit our website at www.xcelenergy.cominaturalgasgrojects. How long is the pipeline in total? The pipeline would be approximately 4.1 miles long. Will the pipeline be tied to Anadarko's Gathering Facility? The pipeline will originate at Anadarko's Lancaster Processing Facility. Will the gas come from well heads in the vicinity of the Project? Will it come from elsewhere? The natural gas will be purchased from Anadarko and will come from their supply of natural gas. Does Anadarko's facility separate oil from gas? Anadarko processes the product at their Lancaster facility, and will be supplying Xcel Energy with only pipeline quality natural gas. That gas is completely processed and delivered into the Xcel Energy system in a state (other than odorization) ready to provide to Xcel Energy customers. Odorization of the gas will be done by Xcel Energy at the Fort Lupton facility. Where will the gas go after it is in the Cherokee Natural Gas Pipeline? Once within the Cherokee Natural Gas Pipeline, the natural gas is transported to the Cherokee Power Plant in Adams County, Colo. It is used at the Cherokee Power Plant for electric generation and to provide gas service to PSCO's future and current customers throughout the region. 3 Lancaster to Fort Lupton Natural Gas Pipeline Project Open House Meeting Summary Report Will the gas end up going outside of Colorado? The natural gas carried by the Project pipeline will be used only within Colorado. How wide will the pipeline be (diameter)? The natural gas pipeline will be 24 -inches in diameter. Will this project bring natural gas service to my house? Everyone in our neighborhood is on propane currently. The Project is a gas transmission project, and, as such, will not serve customers directly. The Project will allow more natural gas to reach Xcel Energy's existing Fort Lupton Metering Station in Weld County, Colo. From there, it will be transported to the Cherokee Power Plant in Adams County, Colo. Customers interested in receiving natural gas service should contact Xcel Energy Customer Care at 800.895.4999, or if not a current customer, the Xcel Energy Builders Call Line at 800-628-2121. Will the gas pressure be lowered along the pipeline route? Gas pressure will remain consistent along the Project route. There will be some slight frictional pressure losses, but those losses are relatively negligible. Who will pressurize the gas? Anadarko or Xcel? The gas will be delivered to the Project pipeline already pressurized by Anadarko. How many users could tap into this line? Since the Project will be a gas transmission line, area customers will not be able to tap directly into the natural gas carried within the Project's pipeline. Customers interested in receiving natural gas service should contact Xcel Energy Customer Care at 800.895.4999 or, if not a current customer, the Xcel Energy Builders Call Line at 800-628-2121. How deep will the pipeline be buried? The pipeline will be buried at an appropriate depth to allow for at least 4 feet of cover between the top of the pipeline and the ground. In other areas, for example where the pipeline needs to be bored to cross roadways, the pipeline will be buried at a greater depth. Will the steel sourced for the pipeline be made in the United States of America? The pipeline will be finished in the United States of America; however, the raw steel product may be sourced from another country. Which side of the existing Cherokee Natural Gas Pipeline will the Project's pipeline run (north/south)? How close can it be located to the existing Cherokee Natural Gas Pipeline? The detailed engineered alignment of the pipeline is still being determined, so we cannot answer this question accurately at this time. 4 Lancaster to Fort Lupton Natural Gas Pipeline Project Open House Meeting Summary Report Where is the local airport located in comparison to the Project area? The Platte Valley Airport is approximately 2.5 miles away from the Project's preferred alignment. What is the green line on the Project map? The green line on the Project map represents the Project preferred route alignment. The orange lines on the Project map represent preferred route alternative segments. Have easements already been acquired for the Project? PSCo continues to work with the Project area landowners in order to obtain all required easements for the Project. 5 Lancaster to Fort Lupton Natural Gas Pipeline Project Open House Meeting Summary Report Appendix A: Notification Area Public Open House Lancaster to Fort Lupton Natural Gas Pipeline Project Open House Meeting Summary Report This page intentionally left blank.

Lancaster to Fort Lupton Natural Gas Pipeline Project Natural Gas Pipeline Safety XceIEnergys RESPONSIBLE BY NATURE® Public safety is at the foundation of all we do The Lancaster to Fort Lupton Natural Gas Pipeline Project has been designed to meet federal and state standards and safety requirements. The safety of the public around Xcel Energy's natural gas system influences every decision made when constructing and operating pipelines. Xcel Energy takes a proactive approach to public safety by implementing safety measures before, during, and after construction. During construction and installation of the pipeline, the following measures occur: • Implementation of a corrosion prevention system designed to eliminate metal loss during the life of the pipeline. • Independent third party x-ray of all pipe welds to verify integrity prior to installation. • Place barriers to allow for a safe construction zone away from the public. Once the pipe is installed, prior to putting it into service, the following steps are taken: • Internal inspection of the inside of the pipe with state-of-the-art equipment. • Internal pressure tests using water to thoroughly verify the integrity of the new pipeline. During the lifetime of the pipeline, the following occurs: • Pipelines are internally inspected at least every seven years with "in -line" inspection technology. • Continuous remote monitoring (24/7) of pipelines and all facility operations by Xcel Energy's staffed gas control center. If you ever suspect a natural gas leak, leave your home or business immediately, and once you are safely outside, call 800.895.2999 or 911 in an emergency.

Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Planning Questions 1. Explain, in detail, the proposed use of the property. Public Service Company of Colorado (PSCo) is proposing to construct and operate the Lancaster to Fort Lupton Natural Gas Pipeline Project (Project) in Weld County, Colorado. The proposed Project would reinforce the natural gas system infrastructure and provide improved and reliable service to existing and future customers in the region. The proposed Project is needed to meet the increased demand for natural gas services as a result of the recent population growth and urban development. The proposed Project would transport natural gas from the existing Kerr-McGee Gathering, LLC Lancaster Gathering Facility, located on the south side of County Road (CR) 22, between CRs 31 and 37 to the existing PSCo Fort Lupton Metering Station, located on the south side Barley Avenue, approximately 0.33 mile east of CR 31 (Exhibit A, Figure 1). The length of the new 16 -inch high-pressure lateral would be approximately 4.1 miles. The proposed Project would include construction of a proposed regulator station located within the Kerr-McGee Gathering, LLC Lancaster Gathering Facility property. The proposed regulator station would be located immediately south of the existing electrical substation owned by United Power Incorporated and west of the agricultural and oil and gas production parcel owned by Robert Warner. The regulator station would require the construction of four buildings, including one remote terminal unit/gas chromatograph (RTU/GC) building approximately 128 square feet in size, one metering building approximately 200 square feet in size, and two control valve buildings approximately 200 square feet in size. One temporary access road running south from CR 22 would be required for access to the proposed regulator station (Exhibit B). The access road would use an existing access off CR 22 that is currently used for the United Power Incorporated substation and run parallel to and east of the eastern property boundary of the Kerr-McGee Gathering, LLC Lancaster Gathering Facility. Up to three additional buildings would be built at a future date at the regulator station and are not part of the scope of this Project. They include one metering building 200 square feet in size and two control buildings, each approximately 200 square feet in size. The site plan for the proposed regulator station is included in Exhibit B. The proposed Project would tie into the Cherokee natural gas pipeline at the existing Fort Lupton Metering Station. Besides the interconnection of the proposed pipeline, up to two new buildings 100 square feet in size would be added to the existing metering station property as part of the proposed Project. The buildings would be used to protect pipeline equipment. Detailed drawings of the proposed Project are included in Exhibit B. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. For 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, see the Pipeline USR questions of the main document, subsection i. J-1 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the zone district in which it is located. The proposed natural gas pipeline route is located in the A (Agricultural) Zone District in Weld County (Exhibit C). Per Section 23-3-40(D)(3) of the Weld County Code, Major Facilities of Public Utilities or Public Agencies, subject to the provisions of Section 23-4-420, are uses by special review and may be allowed in the A (Agricultural) Zone District upon approval of a permit. Per Section 23-3-20(L) of the Weld County Code, utility service facilities are a use by right in the A (Agricultural) Zone District. This Use by Special Review (USR) application requests approval of the proposed Project within the A (Agricultural) Zone District. 4. Describe what type of land uses surround the site. Explain how the proposed use is consistent and compatible with surrounding land uses. The proposed Project would be compatible with the surrounding land uses. Land surrounding the proposed Project is used for agricultural and oil and gas production from the Kerr-McGee Gathering, LLC Lancaster Gathering Station to about 0.5 mile north of Barley Avenue. In the area 0.5 mile north of Barley Avenue and along Barley Avenue, the proposed Project would be located outside the boundary of Aristocrat Ranchettes subdivision, near areas already used for industrial purposes by the city of Fort Lupton. The route surrounding the subdivision is currently occupied by linear corridors including roadways and utilities —primarily electric transmission lines. Both the Kerr-McGee Gathering, LLC Lancaster Gathering Station and the Fort Lupton Metering Station are existing facilities and their continued use for utility service is consistent with the proposed Project. The proposed Project would not interfere with any agricultural operations. Although most of the proposed Project would cross agricultural land, the natural gas pipeline easement would be able to be farmed following construction. PSCo has entered into agreements with landowners to avoid crop damages; however, if disturbance to crops occurs the landowner would be compensated at fair market value and would not impact subsequent growing seasons. The preferred route alternative segments are located in areas used for oil and gas facilities and along city of Fort Lupton property that includes a municipal water tank. The proposed Project is consistent with existing land use in this area. 5. What are the hours and days of operation? (e.g. Monday thru Friday 8:00 AM to 5:00 PM) Construction Construction work hours would be 7 AM to 7 PM Monday through Saturday unless otherwise specified by Weld County. Construction may occur on Sundays and other hours outside the 7 AM to 7 PM timeframe on an as -required basis. If unforeseen circumstances occur, or construction is delayed, PSCo may require construction outside the 7 AM to 7 PM timeframe to complete construction. Construction would occur in one shift. Construction of the proposed Project would be in conformance with all Weld County noise standards (Weld County Code 14-9-10 et seq.) as established in Section 25-12-101, CRS. Once operational, the natural gas pipeline would be in use at all times. J-2 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Operation The natural gas pipeline would be buried underground. No noise would be generated by the natural gas pipeline. The proposed regulator station would be operated continuously (24 hour/day). There would be little to no noise (50-70 decibels) generated by the proposed regulator station. 6. List the number of full time and/or part time employees proposed to work at this site. Construction of the proposed Project would require from 20 to 100 workers on site for a period of approximately 4 months. Once construction has been completed and the Project is operating normally, a single person may be present on the Project site once a week for routine operation and maintenance. 7. If shift work is proposed include the number of employees per shift. Shift work is not proposed at the site. A single person may be present on the Project site once a week for routine operation and maintenance. 8. List the number of people who will use this site. Include contractors, truck drivers, customers, volunteers, etc. Construction of the proposed Project would require from 20 to 100 workers on site for a period of approximately 4 months. A single person may be present on the Project site once a week for routine operation and maintenance. 9. If this is a dairy, livestock confinement operation, kennel, etc., list the number and type of animals. This section is not applicable to the proposed Project, which would be a pipeline facility. 10. Describe the type of lot surface and the square footage of each type. (e.g., asphalt, gravel, landscaping, dirt, grass, buildings) The Project right-of-way (ROW) would be restored to preconstruction conditions with the exception of the proposed regulator station site and associated access road and the proposed buildings at the Fort Lupton Metering Station. The four proposed buildings at the proposed regulator station include an RTU/GC building approximately 128 square feet in size, one metering building 200 square feet in size, and two control valve buildings approximately 200 square feet in size. Up to three additional buildings would be built at a future date and are not part of the scope of this Project. They include one metering building approximately 200 square feet in size and two control buildings, each approximately 200 square feet in size. Up to two new buildings, each approximately 100 square feet in size would be added to the existing metering station property as part of the proposed Project. The buildings would be used to protect pipeline equipment. The site plan for the proposed regulator station and Fort Lupton Metering Station is included in Exhibit B. J-3 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines The pipeline would be approximately 4.1 miles long, and would have a permanent 50 -foot - wide easement and an additional 50 -foot -wide construction easement. Additional information regarding restoration of the Project ROW is provided in Exhibit E. 11. How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed? No parking spaces are planned for the proposed Project. Construction workers would use the existing PSCo property (existing Fort Lupton Metering Station and the proposed regulator station site), and the Project ROW to park during construction hours. 12. Explain the existing and proposed landscaping for the site. The Project ROW would be restored to preconstruction conditions with the exception of the proposed regulator station site and metering station site. The four proposed buildings at the proposed regulator station include an RTU/GC building approximately 128 square feet in size, one metering building approximately 200 square feet in size, and two control valve buildings approximately 200 square feet in size. Up to three additional buildings would be built at a future date and are not part of the scope of this Project. They include one metering building approximately 200 square feet in size and two control buildings, each approximately 200 square feet in size. Up to two new buildings approximately 100 square feet in size would be added to the existing Fort Lupton metering station property as part of the proposed Project. Additional information regarding restoration of the Project ROW is provided in Exhibit E: 13. Describe the type of fence proposed for the site (e.g., 6 foot chain link with earth tone slats) The proposed regulator station would be completely surrounded by 7 -foot security fence topped with a three -strand barbed wire outrigger. The fence would be shared with the existing Kerr-McGee Gathering LLC fence on the west site of the proposed site. Additional temporary chain link fencing or orange exclusion fencing may be used surrounding the staging areas or other construction areas during construction. 14. Describe the proposed screening for all parking and outdoor storage areas. If the site is located in a floodplain, outdoor storage is restricted. The proposed regulator station would be completely surrounded by 7 -foot security fence topped with a three -strand barbed wire outrigger. Additional temporary chain link fencing or orange exclusion fencing may be used surrounding the staging areas or other construction areas. No other screening is proposed. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Upon completion of construction, the Project ROW would be returned to preconstruction conditions with the exception of the footprint of the RTU building and the two metering buildings at the proposed regulator station site, which would remain in place for the life of the J-4 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Project. Revegetation methods are described in Exhibit E. There are no current plans to decommission the proposed Project. However, if the Project is decommissioned and terminated in the future, the regulator station and Fort Lupton Metering Station would be removed and the area would be reclaimed. The natural gas pipeline would be abandoned in place and filled with inert gas that is used to clean out the pipeline and remove natural gas. 16. Who will provide fire protection to the site? The Fort Lupton Fire Protection district would provide fire protection to the site in the construction and operations phases of the proposed Project. 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. An approximate construction sequencing schedule for the Proposed Project is as follows: • Boring and trenching of the pipeline beginning August 2017; expected completion: December 2017 • Construction of the proposed regulator station, including four buildings, gravel surface, 7 -foot security fence topped with a three -strand barbed wire outrigger, and construction of the access road all beginning September 2017; expected completion: December 2017 • Construction of the Fort Lupton Metering Station including up to two buildings beginning September 2017; expected completion: December 2017 • Hydrostatic testing: December 2017 • Commissioned and in-service: December 2017; possibly into first quarter 2018 • Reclamation activities including revegetation and grading ongoing throughout construction and completed September 2018 Reclamation activities including revegetation and grading ongoing throughout construction and completed September 2018 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) Please see Exhibit L for a more detailed traffic narrative. A summary is provided here. The total number and type of construction vehicles that would access the site each day include: • Pickup trucks: 7 trips per day • Welding trucks: 10 trips per day • Non-destructive examination "x-ray" trucks: 6 trips per day • Semi -truck pipe delivery: 4-5 trips per week • "Low boy" equipment transport trucks: 5 per week • Bus/van: 6 trips per day J-5 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines It is estimated that approximately 68 semi -truck pipe deliveries would be required for the proposed Project. These deliveries would take place over about 4 months as necessary for construction of the pipeline, or an average of 17 deliveries per month or an average of 4-5 deliveries a week. A single person in a pickup truck may be present on the Project site once a week for routine operation and maintenance. Trip generation for the construction phase of the proposed Project within unincorporated Weld County would be related to the delivery of materials and equipment to the staging areas, construction activities related to installation of the natural gas pipeline (workers, trucks, and equipment traffic), dust suppression, and hydrostatic testing. It should be noted that the hydrostatic testing of the entire length of the installed natural gas pipeline would be performed at the completion of construction. Construction work hours would be 7 AM to 7 PM Monday through Saturday unless otherwise specified by Weld County. Construction may occur on Sundays and other hours outside the 7 AM to 7 PM timeframe on an as -required basis. Substantial construction of the proposed Project is expected to begin by the end of the summer 2017, with commissioning and testing of the entire natural gas pipeline/facilities expected to be completed by the end of December 2017. The in-service start date of the natural gas pipeline is expected in December 2017, possibly into the first quarter of 2018. The pipeline would be bored under all county road crossings. A Traffic Control Plan would be submitted to the County as required with the County access permit application. The Plan would provide measures for traffic control during Project construction. Road closures are not expected during construction of the proposed Project. 2. Describe the expected travel routes for site traffic. Access to the easement would be on existing roads with the exception of one additional permanent access road required for access off CR 22 to the proposed regulator station. Haul routes and worker traffic to the proposed Project during construction would primarily use CR 22 and Barley Avenue (CR 16). Currently, it is anticipated that the pipe would be shipped by truck from the coating facility in Sydney, Nebraska, directly to the Project. The pipeline materials and appurtenances would be delivered to the Project via U.S. Highway 85 and CR 16 or 22 and staged at the PSCo- owned Fort Lupton metering station or the temporary staging area off CR 22 at the proposed regulator station site. Materials would then be moved to the Project ROW for assembly and installation via CR 31, CR 22, CR 20, and CR 18. As often as practicable, the pipe itself will be delivered, off-loaded, and strung out directly on the pipeline permanent/temporary easement to avoid double handling. Material deliveries and oversized vehicle traffic on public roadways would be limited to off-peak commuting times, as practicable, and staged at the PSCo-owned Fort Lupton metering station or the temporary staging area off CR 22 at the proposed regulator station site. Materials would then be moved to designated locations along the natural gas pipeline for assembly and installation. J-6 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines 3. Describe the travel distribution along the routes (e.g., 50% of traffic will come from the north, 20% from the south, 30% from the east, etc.) It is anticipated that approximately 60 percent of construction traffic would originate from the west (primarily via CR 22 and Barley Avenue). Approximately 20 percent of the construction traffic would originate from the south (primarily via U.S. Highway 85), and approximately 20 percent of the construction traffic would originate from the north (primarily via U.S. Highway 85). 4. Describe the time of day that you expect the highest traffic volumes from above. Peak travel times during construction of the proposed Project are expected from 6 AM to 7 AM and from 5 PM to 6 PM. Materials hauling would take place during various times of the day. 5. Describe where the access to the site is planned. Access to the proposed Project would be from private PSCo-owned easements and fee - owned land, private land, and county thoroughfares along the length of the natural gas pipeline. Existing PSCo facilities and temporary construction easement would be used as staging areas for temporary storage of construction materials and construction vehicle parking. Access to the construction areas and for operation of the proposed Project would be from existing county roads and via the pipeline easement across private property. One access road is proposed from CR 22 to the proposed regulator station using an existing access off CR 22. An access permit application is included as Exhibit D. 6. Drainage Design: Detention pond summarized in a drainage report is required unless the project falls under an exception to stormwater detention requirements per code section 23-12-30 F.1. Does your site qualify for an exception to stormwater detention? If so, describe in a drainage narrative the following: 1. Which exception is being applied for and include supporting documentation. As discussed in the pre -application meeting with Weld County on November 18, 2017, and documented in Exhibit I, pre -application case file, the proposed pipeline would be excluded from the stormwater detention requirements per code section 23-12-30 (F.1) under exception 5: Pipelines or transmission lines. The proposed regulator station would be excluded from the stormwater detention requirements per code section 23-12-30 (F.1) under item 13: A parcel greater than 1 gross acre and less than or equal to 5 gross acres in size is allowed a onetime exception. Drawings of the Project components showing size and location of these proposed components are included in Exhibit B, detailed engineered drawings. 2. Where the water originates if it flows onto the property from an offsite source There are no water conveyances including channels or streams that flow onto the Project ROW from an off -site source. J-7 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines A wetland and other waters of the United States (WoUS) delineation, including a desktop analysis and field survey, was completed as part of the biological resources assessment. The delineation revealed one wetland in the Project ROW. The wetland appeared to be isolated and there were no streams or other surface water features observed in the Project ROW. The proposed Project would avoid all impacts to potential WoUS if practicable. If impacts to wetlands cannot be avoided, PSCo would comply with all federal and state regulations for impacts to potential WoUS. 3. Where it flows to as it leaves the property The proposed Project would cross Riley Mound, a topographic high point. Water flows off Riley Mound in all directions and eventually flows toward Fulton Ditch and Speer Canal, both of which flow to the north. 4. The direction of flow across the property No water conveyances, including channels or streams, are present in the Project ROW. Elevation contours are included on Figure X. After construction, the Project ROW would be returned to preconstruction conditions and contours. Therefore, water flow across the property would not be altered by the Project. 5. If there have been previous drainage problems with the property There are no known drainage problems in the Project ROW. B. Does your site require a stormwater detention pond? The site does not require a stormwater detention pond. Environmental Health Questions What is the drinking water source on the property? If utilizing a drinking water well include either the well permit or well permit application that was submitted to the State -Division of Water Resources. If utilizing a public water tap include a letter from the Water District, a tap or meter number, or a copy of the water bill. This is an unmanned facility and drinking water would not be required during operation. Individual bottled water or water cooler service would be provided to construction workers. The proposed Project would require hydrostatic test water during the final phases of construction. The natural gas pipeline would be pressure tested once backfilling has been completed to ensure that the system is capable of withstanding the designed maximum allowable operating pressure (MAOP). The quantity of water required for hydrostatic testing is approximately 487,000 gallons. Water for the testing would be supplied from an approved municipal water source in the vicinity of the proposed Project and would either be obtained from a hydrant or delivered to the Project site via a water haul truck. J-8 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Water for dust suppression would be obtained from municipal sources approved by jurisdictions in the Project area prior to construction and would be delivered via a water haul truck. Water requirements for dust suppression would be approximately 500,000 gallons. What type of sewage disposal system is on the property? If utilizing an existing septic system, provide the septic permit number. If there is no septic permit due to the age of the existing septic system, apply for a septic permit through the Colorado Department of Public Health and Environment (CDPHE) prior to submitting this application. If a new septic system will be installed please state "a new septic system is proposed". Only propose portable toilets if the use is consistent with the CDPHE's portable toilet policy. The proposed Project is an unmanned facility and a sewage disposal system would not be required during operation. During construction of the proposed Project port -a -lets would be used. 3. If storage or warehousing is proposed, what type of items will be stored? Two material staging and laydown areas would be established, one on the existing Fort Lupton Metering Station parcel and one at the proposed regulator station. Additional staging of materials would occur within the temporary construction easement and temporary usage areas for the pipeline. No other laydown or staging areas would be required. No permanent storage would be associated with the proposed Project. The Project ROW would also be used as necessary to store pipe prior to installation; and to store necessary construction equipment. The staging areas would be utilized for the following temporary uses: • Pipe and pipe materials including valves, fittings, and other miscellaneous materials • Limited parking for employees • Portable toilet • Construction equipment PSCo would provide Weld County documentation from each property owner that states that the property owner has entered into an agreement with PSCo for temporary use of the land, for construction easement, prior to construction. No additional odorant storage would occur during operation of the proposed Project. The mercaptan odorant storage is already on site at the existing Fort Lupton Metering Station in the permanent holding tanks. No storage of materials along the natural gas pipeline easements would occur following completion of construction. J-9 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines 4. Describe where and how storage and/or stockpile of wastes, chemicals, and/or petroleum will occur on this site. Hazardous materials would not be stored in the Project area and no hazardous materials would be generated during construction of the proposed Project. A fueling vehicle or fueling tank would service vehicles within the Project ROW as necessary. No additional odorant storage would occur during operation of the proposed Project. The mercaptan odorant (a sulfur -containing organic chemical substance, sold as Scentinel® E) storage is already on site at the existing Fort Lupton Metering Station in the permanent holding tanks. No storage of materials would occur in the Project ROW following completion of construction. Construction waste would be stored at the staging areas in commercial dumpsters that would be regularly serviced. All construction waste, including trash and litter, garbage, and other solid waste would be removed to a disposal facility authorized to accept such materials. Material disposal (i.e., clean fill) would be taken to approved disposal locations, including but not limited to: • Erie Front Range Landfill, 1830 CR-5, Erie, CO 80516 • Tower Landfill, 8480 Tower Road, Commerce City, CO 80022 • D&R Transfer Station, 6091 Brighton Boulevard, Commerce City, CO 80022 Waste management best management practices (BMPs) for protection of water resources are included in Table 1 of the Application. 5. If there will be fuel storage on site indicate the gallons and the secondary containment. State the number of tanks and gallons per tank. In some instances, the contractor may require a fueling tank. The tank would typically hold approximately 500 gallons. The tank would meet Occupational Safety and Health Administration requirements for secondary containment. Fueling vehicles and tanks would fuel construction vehicles within the Project ROW and at the staging areas as required. Fueling vehicles would be equipped with spill kits and fire extinguishers and personnel would be properly trained in spill prevention, control, and countermeasures. No vehicle maintenance would occur on site, and appropriate BMPs would be utilized and documented if on -site maintenance became necessary. 6. If there will be washing of vehicles or equipment on site indicate how the wash water will be contained. No vehicle or equipment washing would be performed on site during construction or operation of the proposed Project. J-10 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines 7. If there will be floor drains indicate how the fluids will be contained. No liquids would be stored inside any of the proposed buildings. The buildings would have a concrete slab foundation and would be a prefabricated drop over style metal building. 8. Indicate if there will be any air emissions. (e.g., painting, oil storage, etc.) Impacts to air quality in the Project area would be short term, transient, and limited to the construction period. Construction activities would be sequenced and no more than 2,500 feet of the trench would be open at one time. Vegetation clearing, trenching, boring, re -grading, and construction vehicles and equipment may produce fugitive dust or exhaust emissions during the construction phase of the proposed Project. Dust suppression would be conducted during construction. Water for dust suppression would be obtained from municipal sources. No air quality modeling has been completed for the proposed Project. Based on the amount of the temporary disturbance area, PSCo is obtaining a General Construction Permit from the Colorado Department of Public Health and Environment, and preparing a Fugitive Dust Plan and Air Pollutant Emission Notice (APEN). The Fugitive Dust Plan would be completed and the APEN would be obtained prior to construction. Construction vehicles and equipment would be shut off when not in use to limit the amount of exhaust emissions. Wind patterns common to the area would act as a dispersion mechanism for air pollutants. The Project area is in attainment of all National Ambient Air Quality Standards, with the exception of the Front Range ozone control area, which is nonattainment for the 8 -hour ozone standard. No air emissions would result from operation of the natural gas pipeline or Fort Lupton Metering Station. The operation of the proposed Project would comply with the air quality regulations promulgated by the Colorado Air Quality Control Commission. 9. Provide a design and operations plan if applicable. (e.g., composting, landfills, etc.) According to correspondence between Kim Ogle, Weld County Planner, and John Heule, Tetra Tech, on Wednesday January 4, 2017, a design and operations plan will not be required for the proposed Project. 10. Provide a nuisance management plan if applicable. (e.g., dairies, feedlots, etc.) Not applicable. 11. Additional information may be requested depending on type of land use requested. PSCo will gladly provide additional information upon request to the applicant listed in Sec. 23- 2 -510. —Application requirements of this application package.

Label the use of the building and the square footage. Building permits would be obtained for all structures as necessary and would have state - issued insignia. One proposed regulator station and one existing metering station would be required for the proposed Project. The proposed regulator station site would be approximately 100 by 250 feet (25,000 square feet) and include four buildings. The buildings at the proposed regulator station include an RTU/GC building approximately 128 square feet in size, one metering building approximately 200 square feet in size, and two control valve buildings approximately 200 square feet in size. Up to three additional buildings would be built at a future date and are not part of the scope of this Project. They include one metering building approximately 200 square feet in size and two control buildings, each approximately 200 square feet in size. Up to two new buildings approximately 100 square feet in size would be added to the existing Fort Lupton metering station property as part of the proposed Project. The buildings would be used to protect pipeline equipment. The location of these buildings are shown in Exhibit B. 2. Explain how the existing structures will be used for this USR? The proposed regulator station, located at the north end of the proposed pipeline, would be used to control and adjust the pressure of the natural gas in the pipeline before transportation of the natural gas. The existing metering station would be used to document and report the pressure and is the interconnection point for gas delivery into the existing Cherokee natural gas pipeline. 3 List the proposed use(s) of each structure.

Introduction Public Service Company of Colorado (PSCo) is proposing to construct and operate the Lancaster to Fort Lupton Natural Gas Pipeline Project (Project) in Weld County, Colorado. This Traffic Narrative was prepared for the proposed Project to evaluate the potential traffic impacts resulting from the construction and post -construction operation of the proposed natural gas pipeline and associated facilities by PSCo. This Traffic Narrative addresses the trip generation, traffic impacts, mitigation measures, and permits and property agreements required for the construction activities that are to be performed within unincorporated Weld County. The narratives also includes evaluation and discussion of the following elements within unincorporated Weld County: • Project access points • Delivery/haul routes for equipment and materials • Staging areas • Construction traffic • Testing, commissioning, and startup of the proposed Project facilities and natural gas pipeline It should be noted that no level -of -service (LOS) calculations or traffic modeling for roads or intersections within the Project area have been performed since the traffic impacts for the proposed Project will only be temporary (approximately 4 months) with restoration of the impacted areas and county ROWs shortly after natural gas pipeline installation. The proposed Project pipeline route would cross the following Weld County roads (CRs): CR- 20, CR-18, and CR-16 (Barley Avenue). At this time, the pipeline would be bored under CR- 20 and CR-18 and CR-16 (Barley Avenue) would be trenched at a depth that meets County requirements. The CR-16 (Barley Avenue) crossing is located in an area with minimal existing traffic and only minor effects to local traffic would be expected. Right -Of -Way Use and Access permits would be obtained from Weld County for these crossings. A traffic control plan would be submitted to meet the permit requirements. 2. Construction -Related Trip Generation Trip generation for the construction phase of the proposed Project within unincorporated Weld County will be related to the delivery of materials and equipment to the staging areas, construction activities related to installation of the natural gas pipeline (workers, trucks, and equipment traffic), dust suppression, and hydrostatic testing. The hydrostatic testing of the entire length of the installed natural gas pipeline will be performed at the completion of construction. Currently it is anticipated that the pipe will be shipped by truck from the coating facility in Sydney, Nebraska directly to the Project. The pipeline materials and appurtenances will be delivered to the Project via U.S. Federal Highway 85 (US -85) and CR-16 (Barley Avenue) and staged at the PSCo owned Fort Lupton Metering Station. Materials will then be February 2017 1 Lancaster to Fort Lupton Natural Gas Pipeline Project Traffic Narrative moved to temporary construction ROW or easement locations along the natural gas pipeline for assembly and installation via CR-31, CR-22, CR-20, CR-16, and CR-18. Construction work hours will be 7 am to 7 pm Monday through Saturday unless otherwise specified by Weld County. Construction may occur on Sundays and other hours outside the 7 am to 7 pm timeframe on an as -required basis. Substantial construction of the proposed Project is expected to be completed by the end of October 2017, with commissioning and testing of the entire natural gas pipeline/facilities expected to be completed by end of November 2017. The in-service start date of the natural gas pipeline is expected in December 2017. At its peak, the construction of the proposed Project will include from 20 to 100 workers at any one time during the 4 -month period. Workers are expected to commute to the site area from surrounding and local areas using the same roads as described for the haul routes. It is estimated that an average of 60 worker trips on the primary roads to the site area (CR-22, CR-16, CR-31, and US -85) would be necessary per day during construction of the proposed Project. A variety of vehicles will be used during the construction and installation of the natural gas pipeline. Approximately 33 vehicle trips would be required on a daily basis that include vehicles and equipment such as pick-up trucks, semi -trucks, welding trucks, excavators, backhoes, side booms, dozers, graders, and water trucks. Semi -trucks and dump trucks will also be used to transport material and equipment. Water trucks would also be required to supply water for dust suppression during the entire construction period and for hydrostatic testing during the last month of the construction period. The water required for hydrostatic testing would be supplied from an approved municipal water source within the Project area. The total number and type of construction vehicles that will access the site each day include (trips are roundtrips in and out of the Project area): • Worker vehicles: 60 trips per day (on primary roads to Project staging areas) • Worker vehicles: 10 trips per day (on less -travelled roads) • Water trucks (dust suppression assuming capacity of 5,500 gallons): 1 trip per day • Water trucks (hydrostatic testing assuming capacity of 5,500 gallons): 5 trips per day — one month only • Pickup trucks: 7 trips per day • Welding trucks: 10 trips per day • Non-destructive examination "x-ray" trucks: 6 trips per day • Semi -truck pipe delivery: 4-5 trips per week • "Low boy" equipment transport trucks: 5 per week • Bus/van: 6 trips per day It is estimated that approximately 68 semi -truck pipe deliveries would be required for the proposed Project. These deliveries would take place over about 4 months as necessary for 2 February 2017 Lancaster to Fort Lupton Natural Gas Pipeline Project Traffic Narrative construction of the pipeline and would amount to an average of 17 deliveries per month or an average of 4-5 deliveries a week (about 1 delivery per work day). 3. Operation -Related Trip Generation Post -construction activities will be related to normal operation and maintenance at the proposed regulator station and the Fort Lupton metering station. Normal operations and maintenance will be completed by PSCo personnel who will travel to site on average once per week by pick-up truck (1 trip per week). The regulator station will have a small parking area, but this site will be unmanned. The existing Fort Lupton metering station has a parking area. There would be no (or very negligible) effects to area traffic from operation of the proposed Project. 4. Traffic Impacts The following sections identify and discuss critical areas associated with county and state roads and the construction of the proposed Project inclusive of mitigation measures to be implemented as a result of this proposed Project. Critical areas include roads and highways, material delivery to temporary staging areas, construction parking and vehicle storage, natural gas pipeline right-of-way (ROW) and markers, and temporary road and use areas. Affected County Roads and State Highways. The roads and highways within Weld County that will be utilized for delivery of construction materials, construction worker trips, and also crossed by the temporary access road and the natural gas pipeline as part of the construction operations include CR-22, CR-20, CR-18, CR-16 (Barley Avenue), CR-31; and US -85. Truck haul routes from off -site locations for material deliveries to the Project temporary storage area at the Fort Lupton metering station will utilize US -85 and CR-16 (Barley Avenue). It is anticipated that approximately 60 percent of construction traffic would originate from the east (primarily via CR-22 and CR-16/Barley Avenue). Approximately 20 percent of the construction traffic would originate from the south (primarily via US -85); and approximately 20 percent of the construction traffic would originate from the north (primarily via US -85). Peak travel times during construction of the proposed Project are expected from 6 am to 7 am and from 5 pm to 6 pm. Materials hauling would take place during various times of the day. Material deliveries and oversized vehicle traffic on public roadways will be limited to off-peak commuting times, as practicable, when background traffic tends to be lower (i.e., early morning and late afternoon) to minimize impacts to local commuters and for worker safety. Table 1 provides traffic data for Weld County roads that would be used for construction traffic, haul routes, and worker commuting. Impacts to area roads are the greatest for less traveled roads that might see temporary daily traffic increases from construction and commuting of up to 39 percent (CR-18). However, it should be noted that such an increase would be temporary for the time period during which pipeline construction is taking place in the vicinity February 2017 3 Lancaster to Fort Lupton Natural Gas Pipeline Project Traffic Narrative of the intersection with CR-18 (only a portion of the 4 -month construction period). It is also noted that these are maximum worst -case scenario estimates and that it is possible (or even more likely) that the pipeline ROW might be used for construction vehicle movement rather than CR-18 or CR-20. Entry of construction vehicles and commuters to the pipeline ROW would most likely take place from CR-16 and CR-22 with more limited entry via CR-18 and CR-20. Traffic for construction of the regulator station would enter the construction site via CR-22. Table 2 provides traffic data for area state/federal highways that would be used for construction traffic, haul routes, and worker commuting. US -85 might see temporary daily traffic increases from construction and commuting of up to 1 percent. However, it should be noted that such an increase would be temporary for the time period during which pipeline construction is taking place. It is also noted that these are maximum worst -case scenario estimates. Entry/exit of construction vehicles and commuters from US -85 would most likely take place from CR-16 and CR-22. Traffic for construction of the regulator station would enter the construction site via CR-22 and traffic for deliveries would primarily use CR-16 (Barley Avenue). Parking and Vehicle Storage: It is expected that construction worker parking and vehicle storage will be primarily be at the Fort Lupton metering station staging area. However, construction worker vehicles and crew trucks may park along the natural gas pipeline ROW easement if necessary. Construction worker commuting/access routes to the parking areas will be the same as the truck delivery haul routes as described above. On -site parking in the Project area will be within the natural gas pipeline ROW and within the Fort Lupton metering station. No parking will occur within any public ROW. Natural Gas Pipeline: The permanent ROW for the natural gas pipeline will be 50 feet wide. PSCo's construction contractor will obtain the required Weld County ROW permits for the installation of the natural gas pipeline prior to construction as described in the Permit Section below. All county road crossings will be bored. The natural gas pipeline will have permanent markers placed along the centerline of the natural gas pipeline to indicate that a buried natural gas pipeline is located in this area. Access: Access to the proposed Project will be from private PSCo-owned easements and fee -owned land, private land, and county roads along the length of the natural gas pipeline. A temporary access road within the temporary 50 -foot construction ROW will be utilized for travel of construction equipment along the natural gas pipeline in areas where a roadway does not already exist. One permanent access road would be constructed for access off CR- 22 to the proposed regulator station within the existing Anadarko Lancaster Gathering Facility. 4 February 2017 Lancaster to Fort Lupton Natural Gas Pipeline Project Traffic Narrative Table 1: County Road —Traffic Data and Project Construction Trips County Road Name From To Average Daily Traffic (ADT) Truck (heavy) % Total Construction Vehicles (per work day) ADT % increase (construction vehicles) Total Construction Vehicles (heavy trucks per work day) Heavy Truck percent increase Worker Commuter Vehicles* ADT % increase (commuter vehicles) Total Construction and Commuter Vehicles Total ADT % Increase 16 (Barley Ave) 29 31 1948 20 66 3.3% 48 11.0% 120 5.8% 186 8.7% 18 31 Patrick St 417 26 66 13.8% 48 30.7% 20 4.6% 86 17.1% 18 Patrick St 35 600 62 66 9.9% 48 11.4% 20 3.2% 86 12,5% 18 35 37 507 63 66 11.5% 48 13.1% 20 3.8% 86 14.5% 20 31 37 164 56 66 28.7% 48 34.3% 20 10.9% 86 34.4% 20 35 37 136 61 66 32,8% 48 36.7% 20 12,8% 86 38,7% 22 31 37 2186 39 66 2.9% 48 5,3% 120 5.2% 186 7.8% * Average of from 20 to 100 workers on site; it is assumed that most workers would not use CR-18 or CR-20 for commuting Vehicles = trips x 2 Source: Data from Weld County for CRs (received via email on January 18, 2017) Average Daily Traffic (ADT)—the average 24 hour volume, being the total volume during a stated period divided by the number of days In that period.

CDOT Data (accessed January 2017, http:Lldtdapps.cold•adodot.infolotis,TraffcData#ui10110criteria'I 23Itlueltuel ) 6 February 2017 Lancaster to Fort Lupton Natural Gas Pipeline Project Traffic Narrative Staging: The existing PSCo Fort Lupton metering station, proposed Lancaster regulator station, and the temporary pipeline construction ROW would be used as staging areas for temporary storage of construction materials and construction vehicle parking. Truck Loads: Loads delivered by truck would vary in weight based on material being transported. Loads delivered by truck may reach 21 tons. All oversize/ overweight loads will comply with Colorado and Weld County regulations. Bridges in the area of the project include a bridge along CR 22 0.4 mile east of US -85, a bridge along CR 20 just east of US -85, and a bridge along CR 16 1.3 mile east of US -85. These bridges cross irrigation canals and truck traffic with heavy loads for oil and gas production facilities and other commercial businesses and development are common. A review of the Weld County Bridges Map (Weld County Department of Public Works) dated October 2016 indicates all of these bridges are open with no restrictions. Structure conditions along US -85 were confirmed to be good based on a search of available on-line Colorado Department of Transportation (CDOT) information.1 Pipeline deliveries are not expected to exceed bridge load limits; however, permits would be obtained as necessary from CDOT for oversize and/or overweight loads as necessary. 5. Mitigation Measures This section describes mitigation strategies and operational procedures to be applied to reduce the impacts of the proposed Project during construction as described in Section 4 above. PSCo's construction contractor will comply with all applicable federal, state, and local mitigation requirements with the intent to avoid any adverse effect on traffic safety, operation, maintenance, and aesthetic quality of the county road and state highway systems. Natural gas pipeline markers are installed along a natural gas pipeline route to notify people of its approximate location. These markers are approximately 4 feet above ground and occur approximately every 500 feet or in -line of sight, on both sides of road crossings, water crossings, and at all changes in direction. The signs are required by federal regulations for natural gas pipeline safety. These markers will provide adequate warning and location of the natural gas pipeline to local residents and future construction contractors performing work in this area. Construction vehicle traffic on public roadways will be limited to off-peak commuting times as practicable to minimize impacts on local commuters. Truck deliveries would be scheduled during off-peak hours as practicable. To minimize conflicts between the proposed Project traffic and background traffic, movements of normal heavy trucks (dump trucks, concrete trucks, standard size tractor -trailers or flatbeds, etc.) will be minimized (essential deliveries only), to the extent practicable, during these peak times. 1 http://dtdapps.coloradodot.info/otis/HighwayData#/ui/0/2/criteria/085C/226.797/265.763. Accessed January 31, 2017. February 2017 7 Lancaster to Fort Lupton Natural Gas Pipeline Project Traffic Narrative Movements of oversize trucks will be prohibited during peak times to the extent practicable. If possible and considering worker safety, such oversized trucks and material deliveries will occur during parts of the day when background traffic tends to be lower, such as early morning and late afternoon. PSCo will work with local law enforcement as appropriate to assist with Project deliveries. PSCo's construction contractor will obtain the required ROW and access permits as required by Weld County prior to start of construction as explained in Section 6 below. Obtaining the required permits will ensure adequate depth of the natural gas pipeline within the ROW to prevent potential damage to the natural gas pipeline or injury to workers during future maintenance or improvements to the roadways (e.g., installation of storm water channels, culvert crossings, and road base re -work) by the county. The pipeline would be bored under all county road crossings. A Traffic Control Plan would be submitted to the County as required with the County Access Permit application. The Plan would provide measures for traffic control during Project construction. Road closures are not expected during construction of the proposed Project. In addition, PSCo's construction contractor will implement the following mitigation measures: • Maintaining emergency vehicle access to private and public property and work with local firefighters, police departments, ambulance services, and other emergency responders to coordinate activities for effective emergency response. • Posting signs on county- and state -maintained roads, where appropriate, to alert motorists of construction and warn them of slow, merging, or oversize traffic. • When necessary, using traffic control measures such as traffic control flaggers, warning signs, lights, and/or barriers on existing county roads and state highways during construction to ensure safety and to minimize localized traffic congestion. These measures could be necessary at locations and during times when trucks will be entering or exiting highways frequently, such as the intersection of the temporary access road with paved county roads. Given the adequate sight distance, lower vehicle speeds, and relatively low traffic volume experienced on the unpaved county roads (CR-18 and CR- 20), it is not expected that flag men will be required for these unpaved road intersections. • Installing gates or other approved barriers on entrance/exits of the temporary access roads when construction workers are not present to reduce unauthorized access. • Escort (pilot) vehicles would be used for over -sized trucks traveling on the proposed haul routes/roads as required. • Notifying landowners prior to the start of construction near residences. All Project personnel will be instructed and required to obey local speed limits and traffic restrictions to ensure safe and efficient traffic flow. If deemed necessary, PSCo will work with Weld County to establish reduced construction speed limits on impacted roads to improve safety throughout the work zones. PSCo assumes that local and state law enforcement will enforce traffic regulations throughout the Project area. 8 February 2017 Lancaster to Fort Lupton Natural Gas Pipeline Project Traffic Narrative Construction of the natural gas pipeline and related facilities may generate a temporary increase in fugitive dust. During construction, water trucks will patrol work areas to control dust as necessary depending on weather and soil conditions as explained in the Trip Generation section above. PSCo's construction contractor will install stabilized construction entrances/exits at all intersections of the Project access road within the pipeline ROW with paved county roads as necessary. The construction contractor will also remove any significant soil tracked onto paved roads as necessary to prevent safety hazards, dust, or nuisances caused by construction zones near residential and commercial areas and along county roads. PSCo will implement dust control mitigation treatments as required by either Weld County or the Colorado Department of Health and Environment. Once construction has been completed, further dust control mitigation will not be needed. 6. Permits and Property Agreements The following permits will need to be obtained for all temporary and permanent ROW encroachments and access for the roadways within unincorporated Weld County: • Right -Of -Way Use Permit: issued by Weld County Public Works Department • Access Permit: issued by Weld County Public Works Department PSCo's construction contractor will obtain the required Weld County Access and ROW permits prior to construction. All Project construction work will be performed in accordance with the applicable requirements as stipulated in the permits. The construction contractor will also be responsible for any oversized and overweight permits required for delivery of construction materials and components. PSCo's construction contractor will maintain public roads and bridges during Project use and restore these structures to the pre -construction condition in accordance with Weld County requirements if they are damaged during construction. 7. Conclusion The proposed Project would only have minor temporary impacts to local Weld County roads during the 4 -month construction period. The proposed Project will not alter any existing roads, so emergency access to the Project site will not be impeded. Emergency access within the area of the proposed Project during construction activities would be addressed in the Traffic Control Plan that would be provided to Weld County prior to the initiation of construction activities. The proposed Project is located in a rural area of Weld County, so no public transit, bicycle, or pedestrian facilities would have a decrease in performance or safety. The construction traffic and deliveries used to estimate construction traffic represent the February 2017 9 Lancaster to Fort Lupton Natural Gas Pipeline Project Traffic Narrative worst -case scenario for the Project. The information presented in this narrative demonstrates that the Project construction and operational activities would only have minor temporary impacts on the existing traffic conditions or transportation systems in the area during the construction period. 10 February 2017 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Report January 2017 Prepared for: Xcel Energy• 1123 West 3rd Avenue, Denver, Colorado 80223 Prepared by: TETRA TECH 216 16th Street, Suite 1500, Denver, Colorado 80202 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Study Contents Page 1.

Introduction Public Service Company of Colorado (PSCo) is proposing to construct and operate the Lancaster to Fort Lupton Natural Gas Pipeline Project (Project) in Weld County, Colorado. This Project would reinforce the natural gas system infrastructure and provide improved and reliable service to existing and future customers in the region. This Project is needed to meet the increased demand for natural gas services as a result of the recent population growth and urban development. The Project would transport natural gas from the existing Anadarko Lancaster Gathering Facility, located on the southern side of County Road 22, between County Roads (CRs) 31 and 37 to the existing PSCo Fort Lupton Metering Station, located on the southern Barley Avenue, approximately 0.33 mile east of CR 31 (Figure 1). The Project would include construction of a new regulator station located within the Anadarko Lancaster Gathering Facility property. The proposed regulator station would be located immediately south of the existing electrical substation owned by United Power Cooperative and east of the agricultural and oil and gas production parcel owned by Robert Warner. The length of the new 24 -inch steel high-pressure pipeline would be approximately 4.1 miles. The purpose of this Routing Study is to identify pipeline routes in consideration of potential impacts to environmental resources, residential areas, community amenities, existing infrastructure, and businesses, in addition to being economically feasible for PSCo and its rate payers. The pipeline routes must also accomplish the purpose and need of the proposed Project. Resource maps developed for the Routing Study are provided in Appendix A. 1.1 Pipeline Construction The pipeline would require a 50 -foot permanent right-of-way (ROW) and an additional 50 -foot temporary construction ROW. The pipeline will be buried underground. It would primarily be constructed using open -cut trenching techniques, although horizontal directional drilling (boring) may be used to avoid direct ground surface impacts to features existing infrastructure such as existing utilities or roadways. 1.2 Project Need PSCo meets customer needs for safe, reliable, and affordable natural gas service. Federal and state utilities commissions are the governing bodies that regulate the rates and services that utilities such as PSCo may provide. In exchange for the right to provide natural gas services, PSCo is obligated to provide service to any residence or business within its service territory. Accordingly, the proposed Project would provide safe, reliable service to PSCo's current and future customers in the region. With regular maintenance and monitoring, the proposed Project is expected to continue to serve the current population and reliably serve the future growth that is projected. January 2017 1 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Study 2. Routing Process 2.1 Overview of Route Selection Process The route selection process for the proposed Project made use of a multi -phase, multi -step approach as described in the sections below. Routing a new pipeline requires a comprehensive approach that balances various factors including system planning, economics, land use, natural, cultural and environmental resources, regulatory requirements, land rights, and engineering. The preferred route was selected through a process that included the following steps: 1. Study area identification 2. Data collection and resource mapping 3. Preliminary route identification and analysis 4. Route refinement 5. Selection of preferred and alternative routes Field reconnaissance of the preliminary routes was performed in November 2016 to identify on -the -ground conditions not readily apparent through available data/maps or aerial photography and to analyze feasibility of construction methods. Each of these steps is described in further detail in the following sections. 2.2 Definition of Study Area The Project study area, developed based on the purpose and need considerations described above and the required interconnection areas, is shown on Figure 1. For the proposed Project, the study area includes necessary endpoints at the existing Anadarko Lancaster Gathering Facility and the existing Fort Lupton Metering Station. These two existing facilities serve as interconnection points into the existing natural gas infrastructure, and helped define the northern and southern boundaries of the study area. The study area includes approximately 1,000 feet on the north and southern side of each of these endpoints to allow for greater routing flexibility. The western and eastern extent of the study area was based on avoidance of surface water features including drainages and irrigation canals, to allow for the avoidance of residential developments, and to minimize the distance between the two Project endpoints. To the extent possible, pipeline easement (ROW would be acquired from private landowners for a majority of the length of the pipeline. The east/west extent of the area considered for routing was therefore primarily based on existing property boundaries that could be followed by the route within property areas. The study area includes the Aristocrat Ranchettes subdivision, located north of Barley Avenue and northeast of the Fort Lupton Metering Station. The western study area boundary was defined to allow for potential pipeline routing to the west of the Aristocrat Ranchettes subdivision along County Road (CR) 31. 2 January 2017 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Study 2.3 Identification of Major Features within Study Area Major features such as main roadways, residential and commercial area locations (and structures), waterways, and parks were used to help define potential routes, either as opportunities or constraints during the selection of preliminary route corridors. Major features in the study area include: • Aristocrat Ranchettes Subdivision • Residential and commercial structures along roads and in parcels between CR 1616 and CR 22 • Major roadways including Barley Avenue, CR 16, and CR 22. • Existing infrastructure, including electric transmission lines, natural gas pipelines, and oil and gas facilities, distributed throughout the study area • Anadarko Lancaster Gathering Facility • Existing Fort Lupton Metering Station 3. Data Collection and Resource Mapping Data were obtained from multiple sources to identify resources within the study area and were compiled in a geographic information system (GIS) database and are shown on resource maps provided in Appendix A. Relevant data included information about natural resources, land use, and historic resources. Digital geographic data were collected from resource management agencies, state and local governments, counties, and utilities. These resources were incorporated into separate maps illustrating the resources within the study area. Resource maps are included as Appendix A. Figure titles and the data sources contained within the figure are summarized in Table 1.

Aerial data from March 2016 were obtained to view the most recent study area conditions. Visible constraints included residential developments, other buildings, and oil and gas facilities. 3.1.2 Land Use/Zoning 3.1.2.1 Unincorporated Weld County Zoning (see Figure A-12) indicates that the majority of the study area in unincorporated Weld County is zoned as Agricultural. The Aristocrat Ranchettes subdivision is formally zoned as agricultural but is authorized for special use (Case: S-21). This area is currently being used for residential homes. The residential areas are considered constraints because of the possibility of noise and other disturbances in close proximity to residences during construction. Land zoned as agricultural is generally considered an opportunity area because the potential for future disturbance is generally lower than other zoning categories; and agricultural activities can continue above an underground pipeline, making it compatible with pipeline construction and operation. Weld County allows the use of land zoned as agricultural for major facilities of public utilities or public agencies with a Use by Special Review (USR) permit from the Weld County Planning Department, pursuant to Weld County Code (23-3-40). The Weld County Comprehensive Plan (Weld County Code 22-3-10) indicates that planning of public facilities and services in a timely, orderly, and efficient arrangement is a basic objective of the County. This pipeline would be consistent with this goal because it would meet the increased demand for natural gas services as a result of the recent population growth and urban development. 3.1.2.2 City of Fort Lupton Barley Avenue is located within the city of Fort Lupton and would necessarily be crossed by all considered pipeline routes because of its location between the start and end of the Project. A ROW Permit would be acquired from Fort Lupton for construction across or within the Barley Avenue road ROW. Other Fort Lupton properties are located in the study area, including water treatment and storage facilities and other buildings. According to Todd Hodges, Fort Lupton Planner, a Special Use permit would be required if the pipeline were to 4 January 2017 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Study cross these parcels. Zoning within the city of Fort Lupton, in the areas that would be traversed by the route, is zoned as heavy industrial (1-2)'. 3.1.3 EPA -Registered Sites Other land use considerations include the potential existence of contaminated areas. A search of EPA -registered sites (see Figure A-4) was performed to provide an indication of potential concerns. The identification of a site is not necessarily indicative of a contamination issue, although additional research would be required to determine whether an issue actually was present at a site. These sites are scattered throughout the study area. Additional review of more detailed information regarding these sites indicates that the sites are associated with air quality and stormwater regulatory requirements. The sites all appear to be related to oil and gas or electric generation activities. There was no indication in the information of any specific contamination concerns in relation to pipeline routing. 3.1.4 Land Cover and Vegetation Land use and land cover types were identified to indicate which may be compatible or incompatible with pipeline routing. Land cover mapping (see Figure A-6) shows most of the study area to be in areas of undeveloped grassland/herbaceous and cultivated crop vegetation. The Anadarko Lancaster Gathering Facility is shown within land cover as high - and medium -intensity development. The Aristocrat Ranchettes subdivision is shown as developed open space and low intensity developed. Grassland/herbaceous vegetation is generally considered an opportunity for pipeline routing given its low intensity of use. Although cultivated cropland would generally be considered a constraint given its higher level of use and economic value, the pipeline would be located underground and would not interfere with agricultural use. 3.1.5 Existing Linear Corridors Existing linear corridors include major streets, waterways, railroads, and utility lines. Existing linear corridors are considered opportunity areas for pipeline routing because they have already been developed and therefore are generally considered a compatible land use. In addition, these linear corridors generally provide existing access for construction and maintenance requirements. 3.1.5.1 Transportation Major streets (and associated ROW) are considered opportunities for routing alignments in the urbanized area. Figure A-9 includes transportation features. Major east/west street corridors include Barley Avenue (CR 16) and CRs 18, 20, and 22. Major north/south street corridors include Grant Street, Patrick Street, and CRs 31 and 37. Consideration needs to be given to separation requirements between existing utilities (water, gas, electric, etc.) within these roadways and traffic control during construction on busy roads where routes parallel or ' City of Fort Lupton. 2016.

January 2017 5 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Study intersect this infrastructure. No railroads, or federal or state highways are located within the study area. During routing, the Weld County 2035 Transportation Plan, which outlines transportation infrastructure completion and funding goals for Weld County, was consulted. Review of the plan indicates that the proposed Project would not interfere with any plans for transportation development in Weld County. However, recent communication with the city of Fort Lupton has revealed that the city plans to widen Barley Avenue at some point in the future and the city plans to install a water line within the roadway ROW. In addition, Tri-State has proposed a water pipeline that would run along the Barley Avenue ROW in the study area. 3.1.5.2 Existing and Future Utilities Existing utilities include electric transmission lines, substations, and natural gas lines (see Figure A-3). Electric transmission line corridors (including both 230 -kilovolt (kV) and 115kV lines) primarily traverse the study area north/south and are present along CR 31 and from the eastern side of the Anadarko Lancaster Gathering Station to Barley Avenue. East/west trending electric transmission line corridors are present along Barley Avenue and a 115kV line cuts through the center of the study area. A natural gas pipeline corridor traverses the study area from the western side of the Anadarko Lancaster Gathering Station to south of Barley Avenue. These existing utility line corridors were considered for pipeline routing because their current use is consistent with the proposed Project. Additional proposed or planned utilities were identified in the vicinity of the Project. Two water pipeline projects were identified within the Barley Avenue ROW in the study area, including a planned Tri-State water pipeline and a Fort Lupton municipal water pipeline. An easement for a proposed Tri-State transmission line was identified, shown in Figure A-3. 3.1.6 Communication Facilities Several antenna structures, microwave towers, and cellular towers are scattered within the study area (see Figure A-5). Routing of the pipeline would focus on avoiding these facilities. Most specifically, areas within 50 feet of a communication tower structure would be avoided where there are guy wires used to stabilize the towers. 3.1.7 Oil and Gas Facilities Oil and gas well locations were identified through the Colorado Oil and Gas Conservation Commission and are shown on Figure A-11. The study area is indicated to be an area of significant oil and gas production. Areas in the immediate vicinity of oil and gas facilities would be avoided for pipeline routing. A gas or water pipeline can interfere with oil and gas well facilities because both pipelines and well facilities are buried and may present a need for mitigation. Oil and gas facilities can generally be avoided because they represent a relatively small and noncontiguous tract of land. 6 January 2017 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Study 3.1.8 Water Resources, Floodplains Water resources mapped in the study area are shown on Figure A-10 and include major waterways, canals, surface water features, water wells, and National Wetlands Inventory mapping. There are no floodplains located within the study area based on available Federal Emergency Management Agency (FEMA) mapping information. All of these features would generally be considered avoidance areas for the routing alignment. One canal/ditch is shown in the northwestern portion of the study area and the Fulton Ditch is crossed by the study area boundary in the southwestern area. No other surface water features of note are present. No NWI wetlands are shown in the study area. Numerous water wells are shown throughout the study area indicating that groundwater is a significant resource in the area. An area of intense groundwater use is apparent within the Aristocrat Ranchettes subdivision. It should be noted that impacts to water wells would be avoided if practicable by altering the location or width of the pipeline ROW. 3.1.9 Topography and Slope Topography is shown on Figure A-10 and slope is shown on Figure A-8. Riley Mound is shown south of CR 20 in the east -central portion of the study area. Several gravel pits are also noted within the mound. Another hill is located in the very southeastern study area and a gravel pit is also shown in the area. An area of 10 to 25 percent slopes is located in the area of Riley Mound. The only other area of slopes greater than 10 percent is associated with a depression in the Aristocrat Ranchettes subdivision. Steep slopes can present engineering challenges for pipeline construction. Gentle topography and slopes are desirable for pipeline corridors. 3.1.10 Biological Resources Assessment A desktop analysis and a preliminary field reconnaissance were performed to identify wildlife habitat in the area of the proposed Project. No federally listed species were observed to have suitable habitat in the Project ROW. The only state threatened or endangered species determined to have suitable habitat within the Project ROW was the burrowing owl. Burrowing owl surveys are planned prior to construction in the summer of 2017 in accordance with Colorado Parks and Wildlife (CPW) protocol. If burrowing owls are observed in the vicinity of the Project, consultation with CPW will be completed, and recommended seasonal buffers for the species will be adhered to. Because CPW recommended buffers are seasonal, avoidance of the burrowing owl habitat is not necessary. A wetland and other WoUS delineation, including a desktop analysis and field survey, was completed as part of the biological resources assessment. The delineation revealed one potential water of the U.S. (WoUS) in the vicinity of the Project. Impacts to the wetland will be avoided to the extent practicable. If construction within the wetland is necessary, PSCo would comply with all federal and state regulations. January 2017 7 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Study 4. Alternatives Development One preferred route, one alternative route (and route segment), and several preferred route alternative segments were ultimately identified (Figure 2) based on preliminary evaluation of routing options. These route corridors were also field reviewed for engineering feasibility and environmental constraints by Project staff. These routes are also shown on the resource figures in Appendix A. 4.1 Routes Considered The routes considered during the route evaluation are discussed below and are shown on Figure 2. Both the preferred and alternative routes would intersect three roads, CR 20, CR 18, and Barley Avenue. The pipeline would be bored under the county roads to avoid traffic and surface disturbance during construction. Barley Avenue is only subject to local traffic and is not paved. Fort Lupton officials have stated that installing the pipeline through the use of trenching techniques will be acceptable. The alternative and preferred routes are primarily located along rural property boundary edges and edges of existing and planned electric and gas utility easements (Figure A-3) where there are no existing structures. 4.1.1 Alternative Route Segments Considered But Eliminated Several alternative route segments were considered but eliminated due to constraints that made the route unfeasible. The alternative route segments are shown in yellow on Figure 2. One route, which starts on the western side of the Anadarko Gathering Facility and runs south along property boundaries on land used for agriculture and oil and gas production to the intersection with CR 18, on the northern side of the Aristocrat Ranchettes. The route then runs along Patrick Street, located on the eastern side of the Aristocrat Ranchettes subdivision where it crosses Barley Avenue. The segment length is approximately 2.8 miles long. The alternative route was considered because it would follow property boundaries, major roads, and existing natural gas pipeline linear corridors and it would utilize developed land within the Aristocrat Ranchettes subdivision. Additionally, it represents a least -distance option from the Project start point to the Project end point. However, proximity to residences is a primary concern with the alternative route due to disturbance and disruption during construction activities, including noise. Additionally, the alternative route has a start point on the western side of the Anadarko Lancaster Gathering Facility, where there is no space for a regulator station given the existing layout of facilities. An abandoned canal (see Figure A-10) intersects the alternative route near its connection with the Anadarko Lancaster Gathering Facility. The route also has the potential to have greater impacts to roadways and traffic in the vicinity of the residential neighborhoods. An alternative segment runs east from the segment discussed above, just south of Higgins Avenue, to join the alternative route along the eastern side of Grant Street or the preferred route. This route segment would avoid traversing the Aristocrat Ranchettes where residential 8 January 2017 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Study development exists. Because the route that includes this segment has a start point on the western side of the Anadarko Lancaster Gathering Facility, where there is no space for a regulator station given the existing layout of facilities, it was eliminated. In addition, there is little useable space for a continuation of the segment because there are many existing and proposed facilities at the segment's endpoint. A different route segment considered but eliminated runs south from the eastern side of the Lancaster Gathering facility at the site of the proposed regulator station, and runs along property boundaries along an existing 230kV overhead electric transmission line corridor for approximately 2.9 miles to Barley Avenue. This route was considered because it avoids the Aristocrat Ranchettes subdivision and is located along property boundaries. The segment was eliminated due to the numerous proposed and existing electric transmission lines, oil and gas pipelines, and easements that would be crossed by the segment (Figure A-3). Another route segment considered but eliminated runs west along the southern side of Barley Avenue. Any of the three segments that run south from the proposed regulator station could cross Barley Avenue and join this segment to the Project's endpoint, the existing Xcel Energy Metering Station. This route was considered because it runs along property boundaries, and is located along Xcel Energy's existing 230kV transmission line. The segment was eliminated after consultation with the Fort Lupton Planning department. In addition to the numerous water, oil, and gas pipelines already located on the southern side of Barley Avenue, there are several utilities planned for the area, including a Tri-State water pipeline and a Fort Lupton water pipeline. In addition, for the pipeline to avoid existing and planned utilities, the pipeline would be located within the Fort Lupton Road ROW. Fort Lupton plans to widen Barley Avenue in the future, and the pipeline would be subject to restrictions to ensure its location does not interfere with the planned road expansion. The Fort Lupton Planning Department ultimately requested that the pipeline be located along another route if practicable. 4.1.2 Preferred Route The preferred route segment runs south from the eastern side of the existing Anadarko Gathering Facility along an existing Tri-State Electric Easement for approximately 3 miles to Barley Avenue. This portion of the route crosses land used for agriculture and oil and gas production. The route avoids an oil and gas facility south of the CR 20 crossing by veering slightly east and back south of the road. The route also veers eastward in several areas south of CR 18 to avoid oil and gas facilities. The route primarily follows a proposed Tri-State transmission line easement as it continues south across agricultural land to the intersection with Barley Avenue. The route intersects Barley Avenue about 0.2 mile east of Grant Street. A water storage facility is planned on the Fort Lupton parcel south of Barley Avenue. In addition, Fort Lupton has stated that a Special Use Permit would be required if the pipeline was located on that parcel; however, only a road ROW use permit would be required for the preferred route. The route crosses the proposed Tri-State electric easement approximately 0.1 mile north of Barley Avenue to avoid that Fort Lupton parcel. The route continues January 2017 9 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Study south/southwest across Barley Avenue for about 0.25 mile and then runs west avoiding oil and gas facilities within agricultural land for 0.6 mile, along an existing PSCo pipeline easement. The route then turns north for approximately 150 feet and then heads runs west to intersect the existing PSCo Fort Lupton Metering Station connection point. The route south of Barley Avenue is located within land used for agriculture and oil and gas production. There are numerous oil and gas facilities in the area including tanks, wells, and pipeline facilities. Land ownership along the preferred route is private, with the exception of Weld County and Fort Lupton road ROWs. The route is preferred because it avoids the Aristocrat Ranchettes subdivision and it avoids planned and proposed water pipelines within the Barley Avenue ROW. The route will avoid the proposed Tri-State transmission line by running outside the transmission line easement. Access to the preferred route would be from CR 22, CR 20, Grant Street, and Barley Avenue (CR 16). Access would likely also be available along the electric transmission line ROW. The pipeline would be bored at the intersection with County Roads. The city of Fort Lupton has requested a trenching or boring depth under the ROW of at least 8 feet to avoid other existing and planned utilities within the ROW. 4.1.3 Preferred Route Alternative Segments Two preferred route alternative segments were considered to provide flexibility in further route refinement. The preferred route alternative segments are shown in orange on Figure 2. One preferred route alternative segment is located on the northern side of Barley Avenue where the preferred route will cross the Tri-State easement for a proposed electric transmission line. This segment would allow the pipeline to cross the Tri-State easement at a right angle, if required by agreements with Tri-State. It should be noted that AC current mitigation would be installed with the pipeline at the Tri-State crossing to ensure the safety of the pipeline when it is located in close proximity to the proposed electric line. AC current mitigation would protect the line from negative effects by dissipating any capacitive, inductive, or conductive electrical current from the transmission line using grounding techniques. One other preferred route alternative segment runs parallel to the preferred route on the southern side of Barley Avenue. This preferred route alternative segment allows greater flexibility for routing in close proximity of several utility lines in the vicinity of the preferred route. 10 January 2017 Lancaster to Fort Lupton Natural Gas Pipeline Project Routing Study 5. Preferred Route The preferred route and preferred route alternative segments are shown on Figure 3. This route is preferred because it would have the least impacts to residential areas, congested streets, roadway ROW, and farmland. The preferred route would take advantage of an existing electric transmission line and pipeline corridor to avoid potential impacts to previously undeveloped areas. Additionally, sufficient space appears to be available for minor route adjustments if they are needed during the Weld County and Fort Lupton ROW permitting process. The preferred route alternative segments were retained to provide optional alignments within the Barley Avenue ROW. 6. Next Steps Additional field investigations have been conducted for cultural resources and biological resources and to identify any potential contamination within the study area. A Class literature and records search to identify known prehistoric and historic resources located within the preferred route has been conducted. This Class I report was sent to the State Historic Preservation Officer for concurrence. A Phase I Environmental Site Assessment (ESA) has been conducted in accordance with ASTM Standard E2247-08 Standard Practice Environmental Site Assessments for the preferred route. The ESA was completed in conformance with the ASTM E2247-08 standard and EPA All Appropriate Inquiry standard. Further discussion regarding the results of the biological resources report is included in Section 3.1.10. None of these studies have identified resources that would need to be avoided during the routing process. Based on current permitting submittal and review timeframes provided by Weld County and the City of Fort Lupton, PSCo anticipates completing the permitting process by June 2017 and entering the construction phase shortly thereafter. The expected Project completion is during fall 2017.
