Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 1 1. Introduction Public Service Company of Colorado (PSCo), a Colorado corporation conducting business as Xcel Energy, is proposing to rebuild the existing 2.25-mile Glenwood Springs to Mitchell Creek 69-kilovolt (kV) transmission line (Project) located in unincorporated Garfield County (County) and the City of Glenwood Springs (Glenwood Springs or City). The existing transmission line must be rebuilt because it has reached the end of its operational life. The rebuilt transmission line will be in the same alignment as the existing route that connects the existing Glenwood Springs Substation, located northeast of the Glenwood Hot Springs Resort, to the existing Mitchell Creek Substation, located northwest of the Glenwood Meadows shopping center (Figure 1). Approximately 0.20 mile of the existing line occurs within County jurisdiction, with the remaining length within Glenwood Springs jurisdiction (Figure 1). Transmission poles will be placed in 31 locations in Glenwood Springs and 4 locations in unincorporated Garfield County. This Location and Extent (L&E) Review application only addresses the portion of the transmission line and related poles located within County jurisdiction (Figure 2). Xcel Energy is currently coordinating with the City of Glenwood Springs on the portion of the Project located in that jurisdiction. This L&E Review application package was prepared per the requirements of Section 4-111, Table 4-201, and Section 4-203 of the Land Use Development Code as well as the Pre-Application Conference Summary. 1a. Regulatory Framework City code and state statues apply to the Project in addition to County land use permit regulations. The regulatory requirements are described in the following sections and Table 1. All applicable land use, environmental, and construction permits will be obtained prior to the start of and during construction as required. 1b. State of Colorado Colorado Statutory Provisions apply to the Project, including a notice and consultation with local permitting jurisdictions. 1c. Garfield County This updated Garfield County L&E Permit application addresses the 0.20-mile portion of the line that traverses County jurisdiction just north of Donegan Road. Transmission poles will be placed in four locations in unincorporated Garfield County (pole locations 133-136). 1d. City of Glenwood Springs An updated City of Glenwood Springs L&E permit application will be submitted concurrently with this application for the approximate 2-mile portion of the line that traverses City jurisdiction. Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 2 Table 1: Land Use Permit Requirements and Applicability to Project Jurisdiction Title Trigger Statutory Reference Status State of Colorado Notification of Intention to Submit Permit Application for Major Electrical Facilities Filing permit application for location, construction, or improvement of major electrical or natural gas facilities. CRS 29-20-108 (4) (a) On October 22, 2020, Xcel Energy submitted a Notification of Intention to Submit Permit Application for Major Electrical Facilities with the Pre- Application Conference Request for this application. City of Glenwood Springs L&E Permit Project proposed by a publicly owned utility City of Glenwood Springs Code of Ordinances 090.060.050(d) Xcel Energy complying through permit application to the City and subsequent process for approval. City of Glenwood Springs 1041 Permit Site selection of major facilities of any public utility to be located within the City of Glenwood Springs City of Glenwood Springs Code of Ordinances 070.080.030 Xcel Energy has submitted a request for an administrative determination that the Project qualifies as an exemption from this permitting requirement under City of Glenwood Springs Code of Ordinances 070.080.040.

Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 3 2. Application Form The completed Land Use Application is included as part of this permit package, located behind the cover letter. 3. Ownership Documentation The Project includes the replacement and rebuild of an existing electric transmission line between the Glenwood Springs and Mitchell Creek Substations. The original line was constructed within a utility easement corridor held by PSCo. PSCo has made use of existing easements and is in the process of obtaining additional easements along the Project transmission and access routes where needed. See Appendix A for additional detail. Permanent and temporary easements will be recorded in Garfield County after execution of the necessary landowner agreements. Since PSCo has easements underlying the existing transmission line, it holds a recognized property interest in the land on which the development is proposed and does not require the consent of surface landowners to submit the L&E application. Thus, no letters of consent signed by such landowners are included in this L&E Review application. 4. Authorization from Property Owners Xcel Energy has made use of existing easements and is in the process of obtaining additional easements along the Project route where needed. Since Xcel Energy holds non-exclusive easements for the right-of- way for the existing transmission line, it holds a recognized property interest in the land on which the development is proposed and does not require the consent of surface landowners to submit the L&E application. Thus, no letters of consent signed by such landowners are included in this L&E Review application. See Appendix A for additional detail. 5. Authorized Signatures on the Application Authorized signatures from Xcel Energy representatives are provided on the completed Land Use Application, which is located behind the cover letter in this application package. See Appendix A for detail regarding landowner signatures. 6. Statement of Authority A Statement of Authority for trusts, Limited Liability Corporations, or other entities is not needed for this L&E Review application. See Appendix A for additional detail. Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 4 7. Application Fee Based on the Pre-Application Conference Summary, provided as Appendix C, a copy of the applicable Payment Agreement Form is included as Appendix B as to the staff time and materials identified as the application review fees. Any further application review fees determined by the County will be considered by Xcel Energy. 8. Payment Agreement Form A copy of the applicable Payment Agreement Form is included as Appendix B. 9. Pre-Application Conference Summary The Pre-Application Conference Summary provided by the County after the Pre-Application Conference held on October 27, 2020, is included as Appendix C. 10. Vicinity Map A Vicinity Map is included in this application package as Figure 1 and is located at the end of the narrative. 11. Names and Addresses of Property Owners within 200 feet and Mineral Rights Owners The names and addresses of property owners within 200 feet of properties within unincorporated Garfield County crossed by the Project have been provided in Appendix D along with a map depicting the properties. Written notification to mineral estate owners of the public hearing will not be provided for the Project. The state statute commonly known as “The Surface Development Notification Act” (CRS 24-65.5-101 et seq) provides that not less than 30 days before the date scheduled for the initial public hearing by a local government on an application for development, the applicant must send a notice of that hearing by certified mail to mineral estate owners (owners or lessees of the mineral estate under the property which is the subject of the application). Pursuant to the Act, the definition of an “Application for Development” covers a wide range of surface development land use approvals, but certain named development activities are specifically exempt from that definition. One exemption includes applications with respect to utility electric lines which includes Xcel Energy’s transmission lines. Thus, due to the nature and scope of the Project, the transmission line rebuild is exempt from the statutory mineral estate owner mailing notification requirements. Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 5 Accordingly, based on this statutory exemption, Xcel Energy will not be including a list of owners of the mineral estate under the property which is subject to the L&E Permit application. 12. Site Plan A Site Plan map is included as Appendix E. 13. Narrative Description Xcel Energy is proposing to rebuild a section of an existing 69kV transmission line in Glenwood Springs and unincorporated Garfield County to replace aging infrastructure and to ensure continued delivery of economic, safe and reliable electric service to customers in Garfield County and western Colorado. The existing transmission line was originally built in the 1940s, and a portion was rebuilt in the 1960s. The transmission line segment between the existing Glenwood Springs and Mitchell Creek substations needs to be rebuilt because it has reached the end of its operational life. The location of the corridor for the existing line was established more than 70 years ago when about 10,000 people lived in Garfield County, compared to about 60,000 today. Xcel Energy studied alternatives for the transmission line location and evaluated technical design requirements and potential impacts on the environment, community, residents, and businesses in Garfield County. Based on this siting analysis, rebuilding the line in its existing alignment was identified as the preferred alternative. The line will be rebuilt to current industry design standards that include additional measures to reduce wildfire risk and use of the existing transmission line corridor and access routes, where possible. Approximately 0.20 mile of the existing transmission line occurs within County jurisdiction, with the remaining length within Glenwood Springs. The existing route crosses into Garfield County just northeast of the intersection of Donegan Road and Sunny Acres Road and reenters Glenwood Springs jurisdiction just west of Highlands Drive. The rebuilt transmission line will follow the existing route within Garfield County. To ensure safe and reliable access for construction, operation and maintenance, the rebuilt transmission line will be constructed in a 60-foot-wide easement or right-of-way (ROW). This will require negotiations with selected landowners along parts of the existing route to acquire additional ROW width where the existing easement documentation does not meet the uniform 60-foot width requirement. Existing and new ROW will require vegetation management in order to create a safe working and operational space around the improved facilities. The following sections (13a–13g) include a detailed description of the Project, purpose and need, phases of development, regulatory framework and approval criteria. 13a. Type of Tower Construction The rebuilt transmission line will follow the same route as the existing transmission line (Figure 1).. Any future increase in operating value from 69 kV voltage rating for the system, including associated 6 Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project substation modifications, will be subject to future permit requirements, as applicable at that time. The rebuilt transmission line will be constructed utilizing transmission structures that meet current design standards and will be strung with new conductor and optical ground wire. The rebuilt line will be operated at 69-kV but the design standards would allow for future operation at 115-kV. The need to operate at 115- kV will be determined through electric system planning study and in coordination with interconnected utilities such as Glenwood Springs Electric. Operation at 115-kV will require additional equipment or modifications at several electric substations which would be subject to permit requirements as applicable at that time. The rebuilt transmission line will be constructed with steel monopoles within Garfield County. Table 2 compares the existing conditions with those proposed in the rebuild and provides an explanation for any proposed changes. Table 2: Existing and Rebuild Characteristic Comparison for Transmission Poles in Garfield County Characteristic Existing Poles Rebuild Poles Additional Information Material, Color Wood, brown Steel monopole (weathering), brown/rust Steel poles comply with updated design standards and may increase longevity Right-of-way Width 30’ for transmission line 30' to 60’ for transmission line Additional right-of-way may be needed based on transmission line design to provide sufficient clearance to existing buildings and/or to reduce number and height of poles Height of Poles 55' to 62' 58.5' to 65' Increased height needed to comply with current design standards and to provide for future increase in operating voltage of the transmission line Access Required Ground access for maintenance Ground and helicopter access for construction, ground access for maintenance Where access is difficult, helicopters can be used to limit ground disturbance from new road construction Additional Easements Existing easement review underway Up to an additional 30' for transmission line, ground access for construction and maintenance and helicopter fly zones The existing easements date back to as early as the 1920s 13.a.1 Construction Methods Project construction work is expected to occur in phases which generally include the following: construction access and vegetation clearing, equipment mobilization and material delivery, foundation construction, pole placement, conductor stringing, and land restoration. Construction access route improvements, grading and set-up of Temporary Construction Easements (TCEs), along with vegetation work will need to be conducted prior to construction. Proposed access routes will allow construction crews and vehicles to access transmission line pole locations, TCEs and the material staging areas. TCEs will be used to stage construction equipment and materials including temporary construction trailers cranes and steel poles. TCEs are also necessary when stringing the conductor wire. Additional details about TCEs and access routes are discussed in the following sections. Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 7 Vegetation management within the existing and expanded ROW will be required prior to, or in conjunction with, construction. Trees and vegetation growing near the Project ROW can cause downed lines, power outages and wildfire. Vegetation management crews will work to prevent these situations from occurring. Vegetation management involves the use of various types of treatment including removing, pruning, and mowing vegetation and the treatment of vegetation with approved herbicides to ensure safe operations. The extent of this work will vary along the rebuilt transmission line corridor depending on level of vegetation encroachment and additional ROW needs. After the preparation work is complete, work on the transmission poles will begin. The new pole foundations will consist of concrete reinforced with steel that can range in diameter and depth based upon the subsurface conditions. Once construction crews drill the hole for the new pole, the foundation is installed, and the hole is backfilled. Transmission poles will then be placed on the foundation using a helicopter. Helicopter installation involves assembling the transmission poles in the material staging area then transporting the poles by helicopter to installation locations to be lowered into place. Helicopter installation enables access to areas that are difficult for construction vehicles to traverse, minimizes construction impacts such as erosion, and expedites construction. This type of installation improves construction efficiency and helps protect the environment in areas of steep terrain. Due to the nature of helicopter installation and FAA safety requirements, residences located near the transmission poles will be required to evacuated during helicopter installation. Xcel Energy and the construction contractor will coordinate with the FAA during helicopter operations and obtain all required permits. Xcel Energy and the construction contractor will provide residents with prior notice if evacuation is required. The four transmission pole locations (133- 136) in Garfield County will be placed using a helicopter. Once all the transmission poles are in place, the conductor wire is strung using a temporary pulley system attached to the insulators. TCEs will be required at specific angles to ensure the conductor wire is pulled in line with the poles, remaining in alignment. The existing poles will be removed by crane, or in areas of steep terrain, by helicopter and the Project will be energized. After construction, the work areas and ROW will be restored. The Revegetation Plan for all areas disturbed during construction is included in Appendix G. 13b. Height of Towers and any Increase in Height from Existing Towers Existing transmission poles along the transmission line in Garfield County vary from 55 feet to 62 feet in height. Two locations of the new transmission poles will have shorter poles than the existing poles and two locations will have slightly taller poles with new pole heights varying from 58.5 to 65 feet tall. Topography, span length, and adjacent land uses influence the necessary height of transmission poles. Table 3, below, compares the existing and new pole heights at each location in Garfield County. Table 3: Changes to Transmission Pole Heights in Garfield County New Pole Number New Pole Height (ft) Existing Pole Height (ft) Change in Pole Height (ft) 133 65 60 5 134 58.5 62 -3.5 Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 8 New Pole Number New Pole Height (ft) Existing Pole Height (ft) Change in Pole Height (ft) 135 64 55 9 136 59 62 -3 Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 9 13c. Visual Mitigation Over time, residential developments and vegetation have encroached on the existing transmission line ROW, making construction and maintenance challenging. To ensure safe and reliable access for future construction, operation, and maintenance, and to rebuild the line to current design standards, the rebuilt transmission line will be constructed in a 60-foot-wide ROW. There are some areas where existing buildings are within the proposed ROW and a smaller easement may be agreed upon with individual landowners in those areas. Xcel Energy is engaged in negotiations with landowners along the existing route to obtain additional ROW width where the existing easement does not meet 60-feet. Existing and new ROW will require vegetation management to create a safe working and operational space around the transmission line. Vegetation management within the existing and expanded ROW will be required prior to, or in conjunction with, construction. Trees and vegetation growing near the Project ROW can cause downed lines, power outages and wildfire. Vegetation management crews will work to prevent these situations from occurring. Vegetation management involves the use of various types of treatment including the removing, pruning, and mowing of vegetation and the treatment of vegetation with approved herbicides to ensure safe operations. The extent of this work will vary along the rebuilt transmission line depending on level of vegetation encroachment and additional ROW needs. Areas of greatest vegetation disturbance will occur outside of Garfield County. The vegetation removal is not anticipated to be of an extent to create a visual impact to the overall region as a whole. After construction, the work areas and ROW will be restored. The Revegetation Plan, for all areas disturbed during construction, is included in Appendix G. Modifications to transmission pole characteristics will result in a change to the poles’ visual appearance. As described in Table 2, existing brown wood poles will be replaced with steel poles to comply with updated design standards; while the rebuild poles will be grey at installation, they are designed to weather to ultimately take on a brown/rust color. The rebuild poles on average, are slightly taller than the existing poles to comply with current design standards. To ensure compatibility with the proposed transmission line, pole height will change as described in Table 3 above. The changes in pole height and material do not constitute a major impact to the existing facilities. Temporary visual disturbance may occur during construction of the Project due to the need for temporary access roads, the presence of construction vehicles and active work areas, and the use of cranes and helicopters for pole installation. Maintenance activities during operation of the Project are not anticipated to introduce significant visual impacts. The presence of the existing transmission line represents an existing impact, and the Project would rebuild the existing line to bring it into compliance with current design standards. While the Project will result in a wider ROW, as well as several taller poles, and some vegetation clearing, it is not anticipated to impact the character of the surrounding area nor create a new significant visual disturbance. 13d. Visual Modeling or Photo Simulation Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 10 Visual simulations are included in this application in Appendix F. 13e. Easement and Access Information Proposed construction access routes will allow construction crews and vehicles to access transmission line pole locations, TCEs, and the material staging area. Access through private property is being obtained from landowners by Xcel Energy. The private property access to transmission pole locations 133-136 will be from a private driveway located west of Highland Drive and north of Donegan Road. Where practicable, existing public roads and private roads will be utilized during Project construction and operation. Some private roads may require improvements and some new access roads may need to be constructed to accommodate construction equipment and long-term maintenance of the rebuilt transmission line. No new access roads are planned to be constructed by Xcel Energy within Garfield County. Where road improvements are needed, Xcel Energy will acquire any necessary grading, stormwater, and erosion control permits to comply with permit requirements. Appendix H provides the locations of the proposed access routes in Garfield County and the level of improvements needed. 13.e.1 Temporary Access Routes and Improvements Proposed construction access routes will allow construction crews and vehicles to access transmission line pole locations, TCEs and the material staging area. Xcel Energy will utilize existing public and private roads during Project construction, where practicable. Where road improvements are needed, Xcel Energy will obtain any necessary grading, stormwater, and erosion control permits and will engage in landowner negotiations where access roads traverse private property. Temporary access routes will be required during construction to access the existing transmission poles and install new poles. Some temporary access will only be required for crews to walk in and access the pole locations with light machinery. A detailed Grading Plan, outlining the locations of proposed temporary access and levels of improvements needed is provided in Appendix H. 13.e.2 Temporary Construction Easements Xcel Energy will utilize up to 36 TCEs during construction of the Project with one TCE located in Garfield County. TCEs will be used to stage construction equipment and materials including temporary construction trailers, cranes, and steel poles. TCEs are also necessary for construction crew parking and materials setup or when stringing the conductor wire. TCEs will also be used for construction access. The Grading Plan, included in Appendix H, outlines the locations of the staging/fly yards TCEs and areas that will be used for pull sites in Garfield County. The TCE located near pole locations 133 and 134 is within unincorporated Garfield County but will also be used during the construction and installation of Project components within Glenwood Springs (Figure 1). Some TCEs may require grading to level out the area for equipment placement and materials storage. Xcel Energy will obtain permits for this work, as required. At the end of the construction phase, all equipment will be removed from the TCEs. The TCE in Garfield County will be restored generally consistent with preconstruction conditions. Two TCEs will be used as helicopter fly yards during construction including the area north of Traver Trail near pole locations 124-126, and an area within unincorporated Garfield County, west of Highlands Drive Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 11 near pole locations 133-134. These areas will also be used for material staging, helicopter fly yards, and for conductor wire pulling, as needed. 13f. Traffic Information Vehicle traffic controls are not anticipated in Garfield County.

Statement Addressing Review Criteria in Section 4-111.C Section 4-111.C of the Garfield County Land Use and Development Code establishes Review Criteria for applications for a Location and Extent Review as follows: The Planning Commission shall determine whether the project is in general conformance with the Comprehensive Plan. Sections 14.a, 15.a, and 15.b of this narrative describe how the Project generally conforms with the Garfield County Comprehensive Plan 2030, as amended February 26, 2020. Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 12 14a. Conformance with Comprehensive Plan Land use within the existing transmission line easement will remain the same; this Project involves removing aging infrastructure and rebuilding it to current industry design standards that include additional measures to reduce wildfire risk. By doing so, Xcel Energy is ensuring the continued delivery of safe, reliable electric service to customers in Garfield County and western Colorado. This aligns with the purpose of the Comprehensive Plan by protecting the safety and welfare of residents of Garfield County from malfunctions that can result from deteriorating infrastructure. Maintaining an adequate and clear ROW will also help prevent interferences and disruptions in the delivery of electrical service. A detailed narrative regarding how the Project conforms with the Garfield County Comprehensive Plan 2030 is included in Section 15 of this application. 15. References to Sections, Goals, and Objectives of the Comprehensive Plan Garfield County Comprehensive Plan 2030 outlines key policies and strategies in four chapters that support the County’s vision for 2030 (Garfield County 2020a). The Vision for Garfield County is dedicated to managing and directing growth to dedicated Urban Growth Areas and other areas that can accommodate growth cost effectively, in order to create thriving communities while promoting a diverse, sustainable and healthy economy, protecting wildlife, maintain or improving the quality of our natural environment, and preserving the county’s rural and western heritage. (Garfield County 2020a). The following sections (15a –15c) outline how the Project supports specific components of the Garfield County Comprehensive Plan 2030. 15a. Chapter 2 Future Land Use Chapter 2 of the Comprehensive Plan outlines five major themes to support future land use in Garfield County. One theme focuses on development in Urban Growth Areas (UGAs), preferred locations for municipality expansion. According to the Garfield County Future Land Use Map, Glenwood Springs has two UGAs near the Project (Garfield County 2020b). Each community is expected to extend services and infrastructure to development in the UGA that substantially complies with their plan for the UGA (landowners and the respective municipality are strongly encouraged to enter into pre-annexation agreements that provide commitments with respect to extensions of service and infrastructure, densities, etc.).The Project supports maintaining the City’s viability as a town center through the continued provision of reliable electric service to the area. (Garfield County 2020a). This Project supports the Garfield County Comprehensive Plan 2030 Section 4: Economics, Employment and Tourism, Designated areas have encouraged business clusters to develop in incubators, entrepreneurial and existing business have expanded into these areas. The County has played a key role Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 13 in providing traditional and communications infrastructure to specific commerce centers. The Colorado State Demography Office (CSDO) projects that from 2017 to 2040 the county’s population will increase by an average of 1,287 persons per year. This is a 55% increase from the annual average between 2001 and 2017 impacting UGAs. As discussed in Section 13a, the rebuilt line will be operated at 69-kV but the design standards would allow for future operation at 115-kV. The need to operate at 115kV will be determined through electric system planning study and in coordination with interconnected utilities such as Glenwood Springs Electric. Operation at 115kV will require additional equipment or modifications at several electric substations which would be subject to permit requirements as applicable at that time. This ensures safe and reliable service can reach future development in the area, including within the UGAs. This addresses background and key issues identified in the Garfield County Comprehensive Plan 2030. 15b. Chapter 3, Section 4—Economics, Employment and Tourism The vision of Chapter 3 Section 4 of the Garfield County Comprehensive Plan 2030, emphasizes economic development in and around County population centers. The Colorado State Demography Office (CSDO) projections highlight important planning considerations concerning where and how to accommodate the future growth, and how to ensure that public infrastructure and services will accommodate this growth (Garfield County 2020a). By strengthening the existing energy infrastructure and ensuring continued reliable energy service to Glenwood Springs, this Project supports the growth of industrial, commercial, and residential uses in the surrounding areas. 15.b.1 Policy 3—Visual, Traffic and Environmental Impacts Consideration will be given to the visual, traffic and environmental impacts of new or expanded industrial development upon tourism, quality of life resources and community character. The strategy for Policy 3 is to ensure that impacts from industrial development (including mineral extraction) are adequately mitigated to minimize negative impacts on tourism, quality of life resources and community character . Visual Section 13c of this permit application details the anticipated visual impacts of the Project and associated mitigation measures. Because the Project involves rebuilding an existing transmission line in place, it is not anticipated that the Project will result in a new negative visual impact to the surrounding community. Traffic Traffic impacts from Project operations are not expected because the Project would not generate trips more than those already needed for the existing line for maintenance or emergencies. Planned maintenance will occur along the line at the same frequency as it does for the existing line. No operational impacts to daily traffic flows are anticipated. Construction of the Project will involve the use of Highlands Drive, a private road leading to other homes in the surrounding area. Due to its size, Xcel Energy doesn’t anticipate any traffic controls needed for this Project. However, in the other portions outside Garfield County jurisdiction, traffic control will be requir ed due to the length and potential traffic impacts the Project might have in the surrounding community. Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 14 Environmental Impacts The 0.20-mile area where the line will traverse Garfield County is zoned Rural and no environmental impacts should take place since Xcel Energy already has existing poles in the area where the line will be replaced. Outside of Garfield County boundary lines, to the east is City of Glenwood Springs and the zoning is Planned Unit Development (PUD), west of the Project, the area is designated Rural Medium Density (RM1). Areas of greatest vegetation disturbance will occur outside of Garfield County. The vegetation removal is not anticipated to be of an extent to create a visual impact to the overall region as a whole. The existing line location was set more than 70 years ago, when about 10,000 people lived in Garfield County, compared to about 60,000 today. Xcel Energy studied alternatives for the transmission line location and evaluated technical design requirements and potential impacts on the environment, community, residents, and businesses in Glenwood Springs. Rebuilding the line in its existing alignment was identified as the preferred alternative as it resulted in the fewest new impacts along the route. The line will be rebuilt to current design standards that include additional measures to reduce wildfire risk and would use the existing transmission line corridor and access routes, where possible. 15.b.2 Policy 4—Economic Resiliency and Diversity Policy 4 aims to strengthen the County’s economic resiliency for employment and income generation by continuing to diversity the economy (Garfield County 2020a). Several strategies associated with this policy focus on encouraging growth and expansion of existing industries within the County. The Project will not only revitalize and strengthen the electric infrastructure within the County, but it is designed with the ability to operate at 115kV to meet the future demand from the development the County is encouraging. The need to operate at 115-kV will be determined through electric system planning study and in coordination with interconnected utilities such as Glenwood Springs Electric. Operation at 115-kV will require additional equipment or modifications at several electric substations which would be subject to permit requirements as applicable at that time. 15.b.3 Policy 5—Locations that possess physical features and community facilities and services Policy 5 encourages commercial and industrial development in areas with appropriate community facilities and services (Garfield County 2020a). While the Project will continue to provide electric service to the same area as the existing line, the line can be operated at 115kV to support future demand, potentially making the area more attractive to developers. The need to operate at 115-kV will be determined through electric system planning study and in coordination with interconnected utilities such as Glenwood Springs Electric. Operation at 115-kV will require additional equipment or modifications at several electric substations which would be subject to permit requirements as applicable at that time. 15c. Section 8—Natural Resources The vision of Chapter 3 Section 8 of the Garfield County Comprehensive Plan 2030 emphasizes the need to protect and/or mitigate the impacts to biological resources. The Project will be constructed along the existing alignment within the County, reducing the impacts to surrounding land use and resources. Location and Extent Review Application Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 15 15.c.1 Policy 2—Avoid disturbance and mitigation impacts Policy 2 discusses the need to avoid disturbance to wildlife habitat and mitigate potential negative impacts that cannot be avoided. The land use along the Project route within Garfield County is primarily shrubland with nearby residential. Project construction may impact nesting raptors if construction takes place during their breeding seasons. If Xcel Energy constructs during breeding season, raptor nest surveys will be conducted prior to construction to determine whether active nests are present near the Project. Additionally, Xcel Energy will coordinate with CPW should the Project be constructed during bighorn sheep lambing season. Potential impacts to wildlife habitat would be temporary and limited to the construction phase. In areas where grading is necessary, Xcel Energy will revegetate the area after construction is complete; the Project’s Revegetation Plan is included as Appendix G. Because the Project involves rebuilding an existing transmission line in place, it is not anticipated that the Project will result in new, permanent, adverse impacts to wildlife. 16.

GENERAL PROJECT DESCRIPTION Xcel Energy is proposing a line replacement project to rebuild the existing transmission line between the Glenwood Springs Substation (northeast of the Hot Springs Pool) to the Mitchell Creek Substation (northwest of the Glenwood Meadows Shopping Center). The overall project is approximately 2.25 miles in length with approximately 0.25 of a mile of the line located in unincorporated Garfield County. The project under the County's jurisdiction involves 3 4 structures (transmission towers) and access roads/easements for construction. The structures are labelled #131, #132 and #133 on Xcel Energy's plans. The line will generally follow the existing alignment across two properties owned by Josephine M. Kinder and owned by the Shirley L. Zancanella Family Limited Partnership. Minor adjustments to the alignment may be considered. A detailed project summary including vicinity mapping has been provided by Xcel Energy and is attached with this pre- application summary. The original line was constructed prior to County Land Use Regulations in approximately 1950. Upgrades to portions of the line have been completed since the original construction. No record of any previous land use approvals has been found in the County's records and County Staff has determined that the Location and Extent Review is the appropriate review process for the re-build project and is consistent with State Statutes. Xcel Energy has already informed the County of their intent to submit applications to the County, has met with the Board of CounÇ Commissioners to provide them with updates and information on the project, and has consulted with County Planning Staff. ¡I.

Pre-Application Conference Request Project Narrative Project Description public Service Company of Colorado (PSCo), a Colorado corporation doing business as Xcel Energy, is proposing to rebuild the existing 2.25-mile Glenwood Springs to Mitchell Creek 69- kilovolt (kV) transmission line (Project) located in the City of Glenwood Springs and unincorporated Garfield County (County). Approximately 3-4 existing transmission line structures are within Garfield County jurisdiction, and the remaining 2 miles of the transmission line is within Glenwood Springs jurisdiction (approximately 28 structures), (see Attachment 3, Figure 1 Project Overview). The Location and Extent permit application submitted to Garfield County will only address the portion of the transmission line and related structures located in County jurisdiction; however, Garfield County does own a portion of property encumbered by the existing transmission line located within the City of Glenwood Springs. PSCo is currently coordinating with the City of Glenwood Springs regarding the Project and required permits for the portion of the line in that jurisdiction. The existing transmission line must be rebuilt because it has reached the end of its useful life. The line will be rebuilt to current design standards that include improvements to reduce wildfire risk. The rebuilt transmission line will largely follow the existing route that connects the existing Glenwood Springs Substation to the existing Mitchell Creek Substation. Replacement of the line is anticipated to begin in 2021 . Limited access to the existing Glenwood Springs-Mitchell Creek transmission line makes construction and maintenance challenging. PSCo reviewed alternate routes for the transmission line which included evaluating factors such as technical design requirements and potential impacts on the environment, community, residents and business in Garfield County and Glenwood Springs. Rebuilding the line along the current route was identified as the preferred route and will use the existing transmission line corridor and access routes, where possible. A portion of the transmission line (3-4 structures total), portions of two access roads, and one temporary construction easement (TCE) will be located within Garfield County. The various Project components are described below. The descriptions of components included in this narrative are preliminary and subject to change due to final engineering design and landowner discussions. Transmission Line The rebuilt transmission line may follow the existing route corridor or may take one deviation in Garfield County as depicted on the figure (structure numbers are shown on Attachment 3, Figure 2). To ensure safe and reliable access for construction, operation and maintenance, the rebuilt transmission line will be constructed in a 60-foot-wide easement or right-of-way (ROW). This will require negotiations with landowners along the existing route to acquire additional ROW width where the existing easement documentation does not meet 60-feet. Existing and new Glenwood Springs - Mitchell Creek Electric Transmission Line Rebuild Project Pre-Application Conference Request Project Narrative ROW will require vegetation management in order to create a safe working and operational space around the improved facilities. The transmission line will be constructed with steel monopole structures that are expected to be placed within existing and expanded easements or rights-of-way. Table 1, below, compares the existing conditions with those proposed in the rebuild and provides an explanation for any proposed changes.

Access roads in Garfield County are located: 2 Glenwood Springs - Mitchell Creek Electric Transmission Line Rebuild Project a a Pre-Application Conference Request Project Narrative Along and south of private landowner drives, west of Highlands Drive (near structures 131 and 132) North of Donegan Road (near structure 133) \Â/lrere practicable, existing public roads and private roads will be utilized during Project construction and operation. Some private roads may require improvements and some new access roads may need to be constructed to accommodate construction equipment and long- term maintenance of the rebuilt transmission line. Access roads within the County will be constructed to meet County requirements including, but not limited to a Grading Permit. \Mrere road improvements are needed, PSCo willacquire any applicable grading, stormwater, and erosion control permits and comply with permit requirements. PSCo will engage with landowners where access roads traverse private property and will discuss any associated mitigation. Traffic controls may be required near the access to the TCE from public roads during construction activities to ensure the safety of crews and the travelling public. Construction Methods and Temporary Gonstruction Easements Vegetation management within the existing and expanded ROW will be required prior to, or in conjunction with, construction of the rebuilt transmission line. Trees and vegetation growing near the Project ROW can cause downed lines, power outages and wildfire. Utility vegetation management crews will work to prevent these situations from occurring. Vegetation management involves the use of various types of treatment including the removíng, pruning, and mowing of vegetation and the treatment of vegetation with herbicides to ensure safe operations. Due to the steep terrain along the route, some transmission line structures will be installed by helicopter. Structures are not expected to be set by helicopter in Garfield County, but installation methods are still under consideration. Once the transmission structures are installed, crews will string the conductor wire through the structures. To do so, a TCE will be required at specific angles to ensure the line is pulled in line with the structures and the conductor remains in alignment. The TCE within unincorporated Garfield County is located near structure 13't and 132, west of Highlands Drive. The TCE may require grading to level out the area for equipment placement and materials storage. PSCo will acquire permits for this work, as applicable. Structures to be installed by traditional crane method, along with the locations of the proposed access roads, and the TCE in relation to the rebuilt transmission line are shown in Attachment 3, Figure 2. 3Glenwood Springs - Mitchell Creek Electric Transmission Line Rebuild Project Glenwood Springs-Mitchell Creek Elâctric TransmiEsion Line REbuild Projsct I sód6h - ãdinq I'anmMi Lhrk& -*.- ruuøMãiæJælRd) .i Sldcluro lo À4rh Umhamed ¡ frdhiMyMwSt@lü.hlb¡(G¿dddùùnlyÌ len@r.ry Co¡.tudioñ ÉãEóñènB €¡ kMrrûYard¡dlblráSstssinoAe({ãdos) tr**** @rcarnety P O sdbyteß O sd by H.ri4le Frgure 1: Projo(t Overvrew Attachment 3: Gonceptual Site Plan This page intentionally left blank. i r t 'l tl a: : ,l l .j: -t {¡r, Glenwood Springs-M¡tchell Creek Electr¡c Transmiss¡on Line Rebuild Project !-- -l er. t ø-ry e*noury - EÈlitrsfÈnñÉbiLheørdr ', ßóùrdRodå(&idlRil) a fr¿lhin¿ry li6w3ùdl0rèlocàldn(GÞßtrdSúrtr$l a PrdhiiayNèwslMlur.Lodlbt{Gdidd&!n!) f._-l lúæ6rycoßludbn Easmêd O 3'l!rBohwl" crrfrrld ^ñ"nry 7ñni¡0 (7n?n) tr-**" Qrcdrnergy. ffia-n"a o Figure 2: Conceptuâl Site Plan This page intentionally left blank.

This line crosses land within the City of Glenwood Springs (City) and in unincorporated Garfield County (County). The new structures will be within the existing transmission easement and accessed via existing private or public roads, existing and new access routes, by walk-in, or by helicopter. Temporary and permanent grading disturbance has been minimized due to a variety of reasons including the challenges of reestablishing revegetation in disturbed areas. Xcel Enerby has chosen to call this a Revegetation Plan as opposed to a Landscaping Plan as the intent is to restore surface native type ground cover without the larger planting and irrigation effort often associated with a Landscaping Plan. While there are multiple construction types for this project, i.e. temporary pad grading, temporary access grading, structure base excavation, etc., they are all fairly similar. Below is the general sequential approach to minimize disturbance and promote revegetation across the project. This will have to be slightly customized to each construction type and site conditions. 1. Prior to the start of construction, a surveyor will stake pole locations, off-sets, line easement limits, access routes, temporary construction areas, and other locations of importance where field delineation is beneficial. 2. Appropriate Xcel Energy staff, line construction contractor, foundation contractor, earthwork contractor, and erosion control contractor will meet on-site to review the delineated construction impact limits. 3. Flagging or paint used to delineate where perimeter erosion control measures should be placed based on disturbance limits defined by Xcel Energy construction team (item 2 above). 4. Xcel Energy’s erosion control plan developer or erosion control install contractor will collect multiple representative topsoil soil samples for analysis along the transmission line. This analysis will focus on the potential for possible soil amendments (primarily nitrogen, phosphorus, and potassium) during seeding. 3 – 6 samples are expected based on the varying soil conditions along the line. 5. Erosion control contractor team to install perimeter erosion control measures, typically construction fence, boundary fence, sediment control logs, rock logs, and vehicle tracking control per the requirements identified in the State Stormwater Management Plan (SWMP) and City and County Grading permits. 2 6. Perform pre-construction meeting with City and County assuming that inspection and sign-off on erosion control measures is a condition of both jurisdiction’s Grading Permits. 7. Only as necessary for project, trim and remove vegetation for off-site disposal that will directly impact site grading or access. Xcel Energy to utilize trimming as much as practicable to keep root structure in place. 8. In areas where grading (temporary or permanent) is required, strip topsoil (assume top 4 inches of soil) for reuse on site. Topsoil to be segregated from other material. Topsoil to be placed along access or in other areas adjacent grading. Topsoil may be transported from immediate work area due to space constraints. Topsoil that is stockpiled for more than 14 days will be seeded for temporary stabilization. Topsoil stockpiles that are to remain dormant for more than 14 days are to have side slopes no steeper than 1H:1V. 9. Topsoil stockpiles may be placed on undisturbed adjacent ground. In this case, Xcel Energy will place a separation fabric, i.e. Mirafi 140N or like, to provide a physical indicator as to where the stockpile ends and native ground begins. Xcel Energy has had success with this approach as it reduces unwanted disturbance of native ground and allows an undisturbed but lightly ‘compressed’ topsoil layer to bounce back once topsoil and separation fabric is removed. 10. Once permanent cut/fill slopes are graded (primarily compressor pads and structure pads in helicopter delivery locations), they will be covered with topsoil within 14 days and seeded and mulched within another 14 days. This will allow permanent cut/fill face revegetation to commence as soon as possible. Work areas where active construction is anticipated, i.e. flat pad work area is not to be topsoil covered until construction work has ceased. Once construction of permanent pads has ceased, topsoil cover is to be completed within 14 days and seeding and mulching to follow within another 14 days. 11. Once temporary cut/fill slopes are graded, they will be covered with a cover crop within 14 days. This cover crop is to be maintained until work has ceased and permanent grading is restored. Restoration from temporary construction impacts are to include replacement of topsoil, seeding, and mulching. 12. Subgrade excavation material, from grading or structure excavation, will be spread on the access road, exported from the site for off-site disposal, or stockpiled in immediate or near-by work area for future use, particularly in areas with temporary grading impacts that are to have grades restored. Like the topsoil above, subsoil that is stockpiled on undisturbed ground is to have a separation fabric below the stockpile to clearly distinguish between native grade and stockpile material. This will minimize disturbance of the native grade and allow this compressed native grade to bounce back once stockpile and separation fabric is removed. Note: subgrade material is not to be spread on-site in a manner that increases the area of disturbance, i.e. broadcast or pushed outside grading disturbance limit required for drive surface or equipment pad needs. 13. Once construction is completed at a site for permanent grading impacts, i.e. conductor pull/tensioning pads and access roads, the site soil is to be ripped to loosen the subgrade due to soil compaction during construction. Following decompaction, topsoil is to be placed at a depth of 4 inches in a loose manner ready to accept seed. Unlike most topsoil requirements, rock of various gravel sizes less than 6 inches diameter is expected in the topsoil layer which is indicative of native topsoil in this area. 14. Once construction is completed at a site for temporary grading impacts, i.e. mini-excavator pads, the site rough grades are to be reestablished and the subgrade soil is to be bucket compacted to a ‘firm’ condition. Following compaction, topsoil is to be placed at a depth of 4 inches in a smooth but loose manner ready to accept seed. Unlike most topsoil requirements, rock of various gravel sizes less than 6 inches diameter is expected in the topsoil layer and is indicative of native topsoil in this area. 3 15. Soil amendments are to be added per soil analytic recommendations via mechanical broadcast or hydraulic application. City and County approved seed mix is to be spread at appropriate rates given application type, hydraulic, drill, or hand broadcast. The amendment and seed application will vary substantially based on access type with helicopter structures having a different treatment process than areas readily accessible to larger truck traffic, i.e. access for a hydraulic sprayer. In cases of hydraulic application, the seed mix may be applied with the liquid amendment or hand broadcast but in no case is seed to be mixed and applied with mulch. 16. Final erosion control cover for seeded areas will vary based on access to disturbance areas. Helicopter access areas will not have mulch applied as the impact areas are a small footprint, hydraulic and crimp mulching is not available to these sites, and broadcast straw mulch is generally not effective as the product is blown away. Truck access areas will have either straw crimp mulch (on grades less than 10 percent and low rock content soil) or a high quality hydraulically applied mulch, i.e. Flexterra HP-FGM or like, on grades exceeding 10 percent. Xcel Energy generally does not support using erosion control blankets on this project due to concerns about reduced blanket to soil contact and synthetic mesh blankets having a high synthetic content which leads to a wildlife entrapment hazard. 17. Xcel Energy will change erosion control inspection schedule from weekly to monthly inspections once initial stabilization measures (seeding and mulching) have been completed. If there are areas of concern identified during the monthly inspection that need to be addressed (i.e. erosion or lack of revegetation growth), the revegetation contractor will return to the site to address identified issues. 18. Per the required State (SWMP) and local (Grading Permits), Xcel energy will continue to maintain structural erosion control measures across the project until no longer necessary. These will primarily include down-gradient sediment control logs but may include other control measures. The sediment control logs will be fully biodegradable to reduce wildlife entrapment hazards. These measures will be removed when no longer required and seed will be hand broadcast in areas where removal has exposed or disturbed less vegetated soil. 19. Once site has met plant density cover requirements, Xcel Energy will request a post-construction site visit with the City and/or County for jurisdiction closure concurrence. NOTES: · Xcel Energy’s ability to stabilize disturbed areas with vegetation is dependent on many factors within Xcel Energy control. Unfortunately, favorable moisture conditions for germination and continued growth are beyond Xcel Energy control and a key determinate for revegetation. Xcel Energy anticipates adequate revegetation will take multiple years. Xcel Energy frequently returns to sites multiple times that are in the vegetation growth phase to address areas of erosion and reseed and/or mulch as necessary to promote vegetation stabilization. · Xcel Energy hires a separate third-party company to perform the erosion control installation, maintenance, and revegetation as well as another third-party company to perform regular erosion control inspections. These companies have long standing relationships with Xcel Energy. With this approach, Xcel Energy has trained the installation company and inspection company to meet Xcel Energy’s standards and to stay in compliance with state and local permit conditions which improve the restoration trajectory. Xcel Energy’s practice is to continue inspection and maintenance, both performed by third party contractors, until site revegetation is established. Access for the post construction inspection and maintenance will be over prescriptive rights, land owner allowed access, temporary construction easements, and the transmission line easement. 4 · See Grading Plan submittal for location and discussion of temporary or permanent grading impact areas. · Walk in only access paths are assumed to not create a disturbance that requires revegetation. · The staging area north of Structure 125 may not be restored with revegetation depending on landowner agreements. This gravel pit area may be stabilized with native or imported aggregate surfacing.

See Figure 1 below for a general alignment of the proposed line. Figure 1 – Proposed Transmission Line alignment 2 Existing Conditions: The current overhead transmission alignment is primarily constructed with direct embed wood structures that may have guy wires or multiple poles depending on site conditions and conductor tensioning. The existing pole diameter at the ground level is between 12 – 32 inches. The ground surfacing under and immediately around the structures is mounded immediately adjacent to pole and then tapers to match surrounding undisturbed grades. The project is generally built on steeper terrain with some flatter areas along the project’s western third. There is existing access grading and limited leveling near structures in steeper hillsides. As grades become less steep, pre-existing graded access is less obvious or does not exist. Due to the nature of this project, there are currently no permanent water quality features nor existing drainage issues or concerns associated with the transmission line. The Site project area is defined by existing Xcel Energy transmission right-of-way (ROW) or easements and additional area that will be utilized by temporary construction easements. In total, this project area is approximately 20 acres (line length x easement width). However, far less of this property will be impacted by construction since impacts are generally limited to the structure locations and associated access, not the entirety of the alignment. The disturbed area is estimated to be approximately 6 acres, excluding the staging area which was permitted separately. The area of existing surface treatments, i.e. aggregate, grass, and dirt, was not calculated as it will not change due to this project. Proposed Conditions: The line rebuild is in the same alignment as the existing line. The new line structures are generally located within 5 - 20 feet of the existing structure locations in the current line alignment. The proposed structures will be a steel monopole design with one H-frame steel pole structure and either direct bury (tangent structures) or have a concrete pier foundation (corner or dead-end) structures. These structures will be 16 – 32 inches in diameter for direct bury structures and roughly 5-foot diameter for concrete pier foundations. The proposed larger diameter single pole will replace multiple smaller wood poles in numerous locations. During the monopole construction, excavated material that will not be placed back into the excavation will be spread in a thin layer around the pole or removed from the site based on site conditions and landowner agreements. Grading Impacts Where feasible, access to many structures for the project will require utilizing existing access to permit truck or equipment access. Localized pad and access grading is temporary, excluding the small pad grading at the helicopter structures. Temporary and permanent grading impacts are listed below: · New STR 114 – The current structure is on an isolated ‘point’ impacted by past grading (after the existing pole was installed) in the area. The new structure location will require grading changes to the ‘point’ to create access pad fill areas for the new pole construction. These changes impact a minor area and will promote increased site infiltration since grades will be reduced from very steep to 2.5H:1V or flatter. Hillside cuts are not required. · New STR 115 – Prior access grading after the existing pole was installed, has created a narrow access path on the north side of the existing and proposed pole sites. This requires minor cut of the remanent point where the pole is located to create a wider drive path by fill. These changes 3 impact a small area and do not substantively change grades nor surfacing of the area. Hillside cuts are not required. · New STR 141 – The proposed grading for structure access and pad is temporary and the most substantive grading change. During construction, run-on flow will be conveyed through the site. Water quality impacts will be mitigated with the use of up-gradient, intermediate, and down- gradient erosion control measures. Post-construction, topographic grades, topsoil cover, and vegetation is to be restored in impacted areas. Drainage paths and runoff are not expected to change, once area is restored. · New STR 145 & 147 – The proposed grading for both structures is on the north side of Midland Avenue. Limited pad grading is required for foundation construction, setting the structure, and tensioning conductor. As these are temporary impacts, the grades, topsoil, and revegetation will be restored to pre-construction conditions after pad removal. · Permanent helicopter pad grading sites, numerous locations – At the majority of helicopter structure locations, the compressor and structure pad sites require two 6-ft by 6-ft pads, one for safe compressor placement and one for safe structure excavation. Unless directed otherwise by landowners, these pad locations are expected to become permanent pads in the event of future pole work and associated pad reconstruction. These exceptionally small areas of grade modification with the same surface vegetation will have a de minimis impact on stormwater volume, time of concentration, direction, velocity, and water quality. Therefore, a hydraulic analysis of these small, isolated grading impacts will not be performed within local basin stormwater areas. Steel Poles The larger diameter of the proposed structures (i.e. a 2.5 foot diameter existing pole with guy wires compared to a 6 foot proposed diameter pole) will have a de minimus impact on the local stormwater drainage given the structure spacing and the proposed pole diameter increase for the larger basin area for either tangent of dead end structures. Outcome: This project will not permanently change the existing surface water flow paths, overall slopes, impervious surface area, nor time of concentration and therefore will not change the runoff volume, runoff peak, nor conveyance path for the alignment. Based on the project type and the absence of permanent stormwater drainage impacts, this type of replacement project does not require permanent water quality features be implemented.

VEGETATION TRIMMING AND REMOVAL IS EXPECTED IN LIMITED AREA AND WILL ONLY BE PERFORMED WHERE REQUIRED. 2. XCEL ENERGY IS PROPOSING A NUMBER OF AREAS THAT REQUIRE CREATING A 'PULL PAD' TO PARK A CONDUCTOR WIRE TENSIONING TRUCK ON A RELATIVELY FLAT SURFACE. THIS TRUCK REQUIRES OUTRIGGERS TO STABILIZE THE TRUCK. IF PULL PAD GRADING IS REQUIRED, GRADING FOR SUCH IS SHOWN ON THE PLANS. 3. GRADING ACCESS SHOWN AS 'MINI EXCAVATOR' IS FOR ACCESS FOR A TRACKED MINI EXCAVATOR. THIS PIECE OF EQUIPMENT IS NARROWER THAN TRUCK ACCESS AND CAN UTILIZED IN AREAS OF STEEPER (LONGITUDINAL AND CROSS SLOPE) GRADES AND A TIGHT TURNING RADIUS. THE MINI EXCAVATOR WILL REQUIRE A RELATIVELY FLAT 10' BY 20' WORK AREA FOR DIRECT EMBED STRUCTURE EXCAVATION. THESE MINOR PADS ARE PROPOSED TO HAVE 1:1 SLOPES WITH VERY MINOR (TYPICALLY LESS THAN 18 INCH) CUT AND FILL FACES AS THE TRACKED AREA WORK PAD HILLSIDE SLOPES ARE GENERALLY 4:1 OR FLATTER. THESE SMALL WORK AREAS ARE PROPOSED TO BE TEMPORARY AS INDICATED ON PLANS UNLESS OTHERWISE NOTED. 4.

Introduction Public Service Company of Colorado (PSCo), a Colorado corporation doing business as Xcel Energy, is proposing to rebuild the Glenwood Springs to Mitchell Creek 69-kilovolt (kV) transmission line (Project) located in the City of Glenwood Springs (Glenwood Springs or City) and Garfield County, Colorado. This Routing Study: Executive Summary briefly describes the process and methodology used to identify alternative locations for the proposed replacement overhead transmission line and to evaluate whether the Project should be rebuilt along the existing transmission line corridor or along a new route. The objective of this Routing Study is to evaluate alternatives that will have the least impact on the environment, community, residents, and businesses; are economically reasonable; and accomplish the purpose and need of the Project. 1.1 Project Purpose and Need The existing transmission line must be rebuilt because it has reached the end of its operational life. The line will be rebuilt to current design standards that include additional measures improvements to reduce wildfire risk. By doing so, PSCo is ensuring the continued delivery of economic, safe and reliable, and affordable electric service to customers in the Glenwood Springs area and western Colorado. Glenwood Springs Electric Department participates in the Municipal Energy Agency of Nebraska and relies on Xcel Energy’s transmission system for delivery of power to Glenwood Springs. The Glenwood Springs to Mitchell Creek 69-kilovolt transmission line needs to be rebuilt to ensure continued reliable power delivery to customers in Glenwood Springs and Western Colorado. 1.2 Project Description The 2.25-mile existing transmission line (referred to herein as the Existing Route) connects the Glenwood Springs Substation, located northeast of the Glenwood Hot Springs Resort to the Mitchell Creek Substation, located northwest of the Glenwood Meadows shopping center (Figure 1). The Existing Route proceeds west from the Glenwood Springs Substation, scales varying terrain and slopes, runs north of Interstate 70 (I- 70) through commercial and residential areas, and crosses the Colorado River near the Mitchell Creek Substation. Given the existing transmission line right-of-way (ROW) and easements, PSCo is considering rebuilding along the Existing Route. However, the existing line location was set more than 70 years ago, when about 10,000 people lived in Garfield County, compared to about 60,000 today. Limited access to the Glenwood Springs- Mitchell Creek transmission line makes construction and maintenance challenging. The expansion of the Glenwood Springs area, along with other challenges described in this Routing Study, presents the need to also consider alternative routes to compare against rebuilding along the Existing Route to ensure a cost- effective installation that minimizes impacts to surrounding areas and ensures a reliably accessible line. The rebuilt overhead transmission line will be constructed with 115-kilovolt-capable transmission structures and strung with new conductor and optical ground wire. The rebuilt line will initially operate at 69 kilovolts but Glenwood Springs – Mitchell Creek Electric Transmission Line Rebuild Project Routing Study: Executive Summary 1-2 could be upgraded to 115 kilovolts to meet future demand. The rebuilt transmission line will be constructed with steel monopole structures. The height and final design of the transmission structures will depend on location and conditions such as slope, soil conditions, and distance between poles. The Project must cross the Colorado River within the municipal boundaries of Glenwood Springs to reach the Mitchell Creek Substation. The ROW for the rebuilt line is expected to be 60 feet wide. The Study area is shown on Figure 1. Glenwood Springs – Mitchell Creek Electric Transmission Line Rebuild Project Routing Study: Executive Summary 2-1 2. Route Selection Process Routing an overhead transmission line requires a comprehensive approach that balances various factors including electric system planning; economics; land use; natural, cultural and environmental resources; regulatory requirements; land rights; and engineering. The Project’s multi-step route selection process is shown in Exhibit 1 and described in the sections that follow.

The extent of the Study area from north to south is bounded by the steep slopes of the mountain valley that surround the city of Glenwood Springs. The Study area is shown on Figure 1. 2.1.2 Data Collection and Resource Review Publicly available data were obtained to identify resources within the Study area, create resource maps, and populate the comparative matrix used to calculate impacts as part of the alternative analysis and route selection process. Table 1 lists evaluated resources within the Study area that contributed to the development of the routing criteria. Glenwood Springs – Mitchell Creek Electric Transmission Line Rebuild Project Routing Study: Executive Summary 2-3 Table 1: Resources in the Study Area and Resulting Routing Objectives Resource Description Routing Objective Future Land Use Future land use near the Mitchell Creek Substation includes mixed-use and single-family residential north of the Colorado River and industrial and commercial south of the Colorado River. Land uses along the south side of the Colorado River include commercial, industrial, riverside protection, hillside protection, parks/open space, multi-family residential, and mixed-use. The Glenwood Springs Golf Club is located to the north of the Existing Route on land designated for parks/open space. Future land uses north of the Colorado River in Garfield County include urban growth area and residential. Follow property and fence lines where possible to avoid splitting land uses or dividing parcels. Avoid new impacts to land uses such as residential developments and other high-density land uses. Avoid routing transmission line through areas of dense development and parcels slated for future development. Proximate Buildings A large part of the area’s economy is tourism-based, and many hotels are located within the Study area. These hotels are mainly located in two clusters: between Donegan Road and U.S. Highway 6 (US-6) and near the Glenwood Hot Springs Resort. There are several hotels southeast of the Glenwood Meadows Mall. The Existing Route runs through a residential section of north Glenwood Springs. The Existing Route north of the Colorado River is adjacent to medium-density residential areas. Avoid new impacts to homes and buildings so that the ROW is kept clear of existing buildings. Transportation and Existing Electric Infrastructure Transportation infrastructure in the Study area includes the Union Pacific Railroad, I-70, and US-6, all running parallel to the Colorado River. The existing 69-kilovolt transmission line currently serves Glenwood Springs via the Mitchell Creek and Glenwood Springs substations. Parallel existing linear infrastructure (roads and transmission lines) when not constrained by existing development or sensitive resources. Favor paralleling existing and future county and local roads where possible. Avoid federal and state highway ROW where possible. Cultural Resources Southwest of Glenwood Springs Substation is the Hot Springs Historic Area (GSHPC). This area encompasses four sites recognized by the GSHPC as being eligible for the National Register of Historic Places (NRHP), one site eligible for both the State Register of Historic Place and NRHP, and one NRHP-listed historic property. One site listed on the State Register of Historic Places lies approximately 0.15 mile south of the Existing Route at the intersection of Maple and 5th Street. Avoid potential degradation of NRHP-listed sites by routing transmission line away from such sites. Identify other culturally sensitive landmarks or sites by consulting with local county and municipalities and avoid routing transmission line within such sites. Water Resources The major water resource intersecting the Existing Route is the Colorado River. Any transmission line alternative will have to cross the Colorado River given the location of the two Project endpoints. Adjacent to Two Rivers Park lies the confluence of the Roaring Fork River and Colorado River. Minimize pole placement in areas prone to flooding such as 100-year floodplains. Minimize impacts to sensitive resources by spanning wetlands, routing around wetlands, or through careful transmission structure placement. Glenwood Springs – Mitchell Creek Electric Transmission Line Rebuild Project Routing Study: Executive Summary 2-4 Resource Description Routing Objective Avian Species Habitat Large areas of potential burrowing owl habitat in Glenwood Springs include Two Rivers Park, the Glenwood Meadows Mall, and the West Harvard Drive neighborhood. However, some of these areas may not be suitable for burrowing owl occupation due to existing development. Peregrine falcons commonly occupy areas that feature open spaces with high cliffs overlooking rivers and coastlines. A peregrine falcon nesting area can be found approximately 0.4-mile northeast of Glenwood Springs Substation. A great blue heron foraging area begins where the Colorado River the Roaring Fork River intersect; this foraging area buffers the Colorado River and encompasses the land around the Mitchell Creek Substation. Reduce potential impacts to sensitive species habitat by identifying a Colorado River crossing with existing disturbance (e.g., near a road or transmission line crossings). Reduce potential impacts to avian species by avoiding nest locations. Glenwood Springs – Mitchell Creek Electric Transmission Line Rebuild Project Routing Study: Executive Summary 2-5 2.2 Routing The next phase of the route selection process was the development and evaluation of alternative routes. This phase included defining the routing objectives, identifying river crossing locations, identifying route segments, and eliminating preliminary routes. 2.2.1 Define Routing Objectives Resource data were analyzed to determine objectives for the transmission line route. The resources were reviewed, and compatible and avoidance areas were considered as general guidance when selecting preliminary route locations within the Study area. While it is not possible to avoid all incompatible areas, classification of objectives in this manner helps maximize utilization of compatible areas and minimize impacts to avoidance areas. The routing objectives are summarized in Table 1, and the preliminary route corridors that resulted from use of the objectives are shown on Figure 2. 2.2.2 River Crossing Identification Given the location of the Project endpoints, the rebuilt transmission line must cross the Colorado River. Crossing locations were identified based on resource data collection, mapping, and field reconnaissance. Preference was also given to areas where the Colorado River narrows, allowing a shorter crossing, to areas with an existing disturbance, and to areas where development is sparse on either side. Additional factors aiding in the crossing location identification include existing linear corridors and future land use designations. Four river crossing locations were identified in the routing process and are shown on Figure 2. Three crossings were carried forward into the comparative process. 2.2.3 Preliminary Route Corridor Identification Preliminary route corridors were identified based on resource data, mapping, field reconnaissance, routing objectives, and river crossing locations. Other factors influencing the identification of preliminary route corridors included the presence of existing linear infrastructure and physical barriers such as buildings and residences. Linear infrastructure can be paralleled to avoid further fragmenting the surrounding Study area; and physical barriers are avoided to ensure the ROW is clear of buildings. Crossing locations for the Colorado River determined the endpoint of each route corridor. Additional routing considerations are described in Table 1. A viable option to meet the Project need is to rebuild the transmission line in the Existing Route corridor. This corridor follows the Existing Route; however, the rebuilt line will require additional ROW width in some areas, additional vegetation clearing, and relocation of some structures that are near cliff edges and near residential buildings. A route corridor along US-6 was identified based on the presence of an existing linear corridor. Additional route corridors that follow existing local roads and avoid residential areas include those running north and south of Midland Avenue, north and south of Devereux Road, and south of Wulfsohn Road. Preliminary route corridors identified are shown on Figures 2 and 3. Glenwood Springs – Mitchell Creek Electric Transmission Line Rebuild Project Routing Study: Executive Summary 2-6 2.2.4 Preliminary Route Corridor Elimination Routes retained for additional consideration and comparative analysis are evaluated in greater detail in Section 2.3. In most cases, if a constraint was found along a route corridor, the corridor was eliminated from further consideration. Any other route corridors connected to the eliminated corridor became obsolete and consequently eliminated. Eliminated route corridors were not carried into the comparative analysis described in Section 2.3. 2.3 Evaluation, Consultation, and Selection The final phase of the route selection process was the evaluation and comparison of the remaining route corridors, consultation with key stakeholders, and the selection of a preferred route. The alternatives being carried forward into this step include the Existing Route (Rebuild Alternative 1), the alternative along Midland Avenue and crossing the Colorado River near Iron Mountain Hot Springs (IMHS) (Rebuild Alternative 2), and the alternative along Midland Avenue and crossing the Colorado River along Devereux Road (Rebuild Alternative 3; Figure 4; Figure 5). 2.3.1 Route Comparison and Evaluation A data matrix comparing end-to-end route combinations across various criteria was created using a Geographic Information System database. The matrix was used as a tool to compare the route alternatives against each other. In the comparative analysis, new impacts are defined as impacts to areas previously undisturbed by transmission line infrastructure. Impacts along segments of the Existing Route, which consists of areas with existing impacts from transmission line infrastructure, are not considered new impacts. The matrix compares the numerical results of criteria such as engineering factors, land use, residences, natural resources, and cultural resources. The results of the comparative route matrix are discussed below. Fifteen route segments were evaluated in the segment comparison portion of the data matrix. When combined, these segments created end-to-end combinations (Figure 4) including Rebuild Alternative 1, Rebuild Alternative 2, and Rebuild Alternative 3. The comparative matrix provides both end-to-end measurements and quantifies the incremental change and the new impacts of each alternative. Incremental change is quantified by considering only the impacts in new locations outside of the existing transmission line corridor. Rebuild Alternative 1 will have the least amount of incremental change because it uses an existing transmission line corridor. Both Rebuild Alternatives 2 and 3 result in additional incremental change since they are located primarily outside of the existing transmission line corridor. Table 2 below shows an abbreviated version of the comparative route matrix results of the end-to-end combinations. The green highlighting shows the alternative with the least amount of new impact.

Glenwood Springs – Mitchell Creek Electric Transmission Line Rebuild Project Routing Study: Executive Summary 2-9 2.3.2 Route Selection Rebuild Alternative 1 was selected as the preferred alternative for the Project. Several factors led to the conclusion, including avoidance of creating new impacts and obtaining all new easements. It is favorable to replace and improve the Project along the existing transmission line corridor rather than create entirely new impacts in new locations. Rebuild Alternative 1 avoids creating new impacts to the area because it will upgrade the current transmission line along the existing easement. Along with construction, other maintenance will be completed including vegetation management. Creating a new Colorado River crossing location of the transmission line would be difficult as it will cause new impacts at a new location, including visual impacts. In addition, the alternative Colorado River crossing locations that were considered are located near recreational resources that may impacted by the Project. Rebuild Alternative 1 avoids a proposed new mining haul route along Devereux Road. The proposed mining haul route is problematic and adding utility facilities to this corridor may cause additional impacts. While Rebuild Alternative 1 does have the largest number of residences in proximity to the centerline and the longest length in areas zoned residential, these residences will be experiencing a replacement of existing facilities, not a new impact. The incremental change to residences in the existing corridor is preferable to new impacts to residences located elsewhere, and re-negotiating the existing ROW is preferable to obtaining new ROW with new landowners. In some cases, small adjustments to the preferred alternative final route can be made to accommodate landowner preferences. The Project, as proposed, mitigates impacts to landowners by upgrading the existing transmission line so that it is less vulnerable to starting or being damaged by a wildfire, thereby increasing the overall reliability of the electric system. Wildfires pose a significant threat to communities and this Project will proactively minimize ignition risks. Additionally, Rebuild Alternative 1 avoids new impacts to areas zoned Hillside Preservation (HP) and Resort (RE), avoiding potential restrictions on development and impacts to tourism areas. Rebuild Alternative 1 utilizes existing crossings of I-70 and US-6. This avoids new impacts in new locations that would result from new crossings and potentially avoids the requirement for new permits and agreements with the Colorado Department of Transportation (CDOT). Glenwood Springs – Mitchell Creek Electric Transmission Line Rebuild Project Routing Study: Executive Summary 3-1 3. Next Steps 3.1 Permitting The land use permits likely to be required for the Project are listed in Table 3; ROW and construction permits are not included in Table 3. There are several permits that have been considered but will likely not be required. The need for a Section 404 Clean Water Act permit at the Colorado River crossing for the Project is considered unlikely. The section of the Colorado River in Glenwood Springs is not considered a traditionally navigable water and is therefore not subject to Section 10 of the Rivers and Harbors Act. Wetland impacts that would trigger or require permitting under Section 404 are not anticipated. In addition, the Glenwood Springs Municipal Code (Article 070.040.040) requires a 30-foot setback from the ordinary high-water mark (Section 404 jurisdictional boundary) of a river or live stream. The Project will be subject to Glenwood Springs and Garfield County’s Location and Extent permitting requirements.

Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project 1 Public Outreach Summary 1. Introduction Public Service Company of Colorado (PSCo), a Colorado corporation doing business as Xcel Energy, is proposing to rebuild the existing 2.25-mile Glenwood Springs to Mitchell Creek 69-kilovolt (kV) transmission line (Project) located in the City of Glenwood Springs (Glenwood Springs or City) and unincorporated Garfield County. The existing transmission line must be rebuilt because it has reached the end of its operational life. The rebuilt transmission line will largely follow the existing route that connects the Glenwood Springs Substation, located northeast of the Glenwood Hot Springs pool, to the existing Mitchell Creek Substation, located northwest of the Glenwood Meadows shopping center. This Summary Report includes a description of PSCo’s approach to public outreach to date, including details about the Project’s virtual town hall held on May 25, 2021. PSCo organized the virtual town hall to update the communities about the Project and anticipated construction methods, answer questions, and gather feedback. Section 1 of this Summary Report provides an overview of public and jurisdictional outreach efforts conducted during Project planning. Section 2 discusses the Project’s target audience and the methods used to notify the public of the virtual town hall. Section 3 describes the purpose and approach of the virtual town hall and an overview of the attendance and comments provided at the virtual town hall. 1.1 Jurisdictional Meetings PSCo first introduced the Project to Garfield County and City of Glenwood Springs representatives in 2018 and has continued to meet with both jurisdictions through the Project planning phase. These meetings have focused on Project updates, concerns with potential rebuild locations and vegetation removal, planned geotechnical work, approach to community engagement and outreach, permitting requirements, Project schedule, and impacts during construction. Table 1 lists the different departments that have been engaged in Project discussions. Table 1: City and County Departments Engaged During Project Planning City of Glenwood Springs Garfield County Community Development Department City Administration Department City Manager Public Works Department Engineering Glenwood Springs Electric City Attorney City Council Community Development Department Board of County Commissioners Three meetings with jurisdictions conducted in 2020 were open to the public. On July 13, 2020, and October 19, 2020, PSCo made presentations at the Garfield County Board of County Commissioners meetings. The intent of the first meeting was to provide an informal presentation about the Project; during the second meeting PSCo requested permission to enter a County-owned property located in Glenwood Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project Public Outreach Summary 2 Springs to perform surveys and studies for the Project. On August 20, 2020, PSCo appeared publicly before the Glenwood Springs City Council to provide information about the Project, address questions, and receive feedback. 1.2 Publicly Available Resources A hotline, email address, and website were created for the Project in 2020 to provide information about the Project to stakeholders and the interested public. The Project hotline and email address provide updates through the voicemail greeting and email autoreply. Updates are also posted to the website’s homepage and content pages. 2. Project Communications and Stakeholder Outreach for the Virtual Town Hall PSCo hosted a virtual town hall on May 25, 2021, to provide information about the Project, construction methods, and schedule and to solicit public feedback. Stakeholders considered during the notification period included landowners and occupants within a 1-mile radius of the Project route. Prior to the virtual town hall, PSCo corresponded with existing and future easement holders along the Project route to discuss the Project and any additional easements required. Outreach activities will continue through Project duration. 2.1 Notifications for the Virtual Town Hall Several forms of communication were used to notify stakeholders of the virtual town hall, including postcards and a website update. Table 2 summarizes the methods used to notify the public and stakeholders of the virtual introductory meetings.

Working with Landowners Easement Acquisition •Easements authorize a utility to use the land within an area known as the Right-of-Way to construct, operate and maintain the transmission line and related facilities •We use market data from recent sales of similar properties to determine fair and appropriate compensation •Every effort will be made to reach a negotiated settlement for the purchase of the easement Working in the Right-of-Way •The landowner typically retains the right to conduct activities within the easement provided the use does not interfere with the transmission facilities •Activities that are not permitted are those that jeopardize the integrity of the transmission facilities or reduce the ground-to-line clearance (tall growing trees, buildings) •Exercise caution when operating tall equipment, moving irrigation pipes, fueling vehicles, or conducting other activities to prevent electrical shock or contact with the line © 2021 Xcel Energy 25 Construction Methods Temporary Construction Easements (TCE) •Conductor wire stringing •Stage construction equipment and materials •Helicopter fly yards Traditional Crane •Assemble structures at TCE, then truck transport •Crane lifts structures into place Conductor Wire Installation •Temporary pulley system pulls the conductor wire to each structure •TCE locations required at specific angles to ensure wire is pulled in line with structures •Conductor wire attached to insulators Restoration Plans •Developed for areas disturbed by construction 26 Helicopter Use Helicopter Use •In areas with steep terrain and limited access •Assemble structure at Temporary Construction Easement, then transport by helicopter to installation location File plan with Federal Aviation Administration (FAA) and follow all regulations and safety requirements •Limits on flying over occupied buildings, roads, and operational Glenwood Gondola More information to be provided as construction plans are completed – Location & Extent permit applications, communications with landowners/businesses, updated website © 2021 Xcel Energy 27 What to Expect During Construction No electrical service interruptions anticipated During construction •Additional noise •Lane or road closures during some activities •Prior notice about activities in your area © 2021 Xcel Energy 28 Safety Wildfire Mitigation •Vegetation management •Current design standards •Virtual Town Hall, June 10: xcelenergywildfireprotection.com Construction •Compliance with federal, state and company safety standards •FAA compliance for helicopter use Programs for Operational Safety © 2021 Xcel Energy 29 xcelenergy.com/outages_and_emergencies/public_safety Rebuild Process and Schedule* © 2021 Xcel Energy 30 2019 –Winter 2020 •Evaluate alternative locations and select rebuild route 2020 –Spring 2021 •Contact landowners and the surrounding community to provide details about the rebuild •Work with landowners on transmission line and access route easements 2020 –Spring 2021 •Geotechnical studies •Determine pole locations and finalize structure design •Identify construction and maintenance access routes Spring 2021 –Summer 2021 •Continue to work with landowners on transmission line and access route easements, and temporary easements for construction •Identify and obtain any necessary Glenwood Springs and Garfield County land use permits •Identify and obtain any necessary construction permits Late 2021 •Clear vegetation along access routes and within transmission line right-of-way •Install new transmission line structures and conductor wire using ground equipment and helicopter •Remove existing structures and conductor wire 2022 •Complete construction, restore work areas, test and energize transmission line * Information subject to change Where to Find Project Information Website: XcelEnergyGlenwoodRebuild.com Call toll-free: 833-947-2040 Email:Info@XcelEnergyGlenwoodRebuild.com © 2021 Xcel Energy 31 32 Question-and-Answer Session •How to ask questions –If you’re joining via phone, enter *3 to ask a question –If you’re joining via web, type your questions into the comment area © 2021 Xcel Energy Kelly Flenniken Director, Community Relations Josh Peterson Principal Transmission Engineering Braileigh Jay Principal Siting & Land Rights Agent Pete Harrington Vegetation Management Lucas Moore Transmission Construction Contractor Jennifer Chester Siting & Permitting Consultant Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project Public Outreach Summary Appendix C: Virtual Town Hall Q&A Session Summary This page intentionally blank. Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project Virtual Town Hall–May 25, 2021 Question and Answer Session 1. Why is the line being rebuilt in place? What about routing along Highway 6 and 24? a. The team looked at several route options including along the existing alignment and the highways as a part of the routing study. Routes along the highway have some limitations for access and being able to construct. Required setbacks from the roadway ultimately prevented us from routing the line there. Ultimately, the team decided to rebuild along the existing route. 2. How will vegetation trimming be conducted? I’m also concerned about rock fall during construction. What will you do about the rockfall concern? a. Tree crews will be trimming vegetation along the rebuild route on foot. With the proposed increase in line height, we’ll actually have to do less trimming in the future. When construction crews dig on hillsides and slopes, barrier fences are installed below them. The lower portions of these fences are buried and staked, so when crews are removing spoils, any falling debris will be caught by the fence until the crews can backfill and restore the work areas. 3. Will Xcel Energy be doing any survey, GIS, or engineering design for this project? a. From a construction standpoint, PAR will build to the design specifications and prints provided by Xcel Energy. About a year and a half ago, lidar surveys were completed to assess the topography along the line and assist with the design of the design transmission line. All that work has been completed and the line is ready to be constructed. 4. When will you share the design of the poles with the impacted property owners? a. Now that we have a final design, Xcel Energy land agents will share this information when discussing offers with property owners. 5. Have impacted landowners been notified regarding the additional easements required? a. All landowners that will be impacted by the Project have been contacted, however not all offers have been mailed at this time. We’ve started the discussion with landowners about needing additional transmission line easements. We will also be acquiring permanent access easements, temporary construction easements, and temporary access easements. 6. Will you make this information available in Spanish? a. Yes. We can arrange to translate this information in Spanish. 7. Why were wood poles used in the canyon for the Shoshone rebuild and metal poles are proposed for this rebuild? a. That decision had to do with timing. It would have taken anywhere from 12-20 weeks to get new steel poles from the steel vendor for that section of line. The pressure was on to get the line back in service through the canyon as soon as possible, so crews used the available materials we had at the time. Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project Public Outreach Summary 8. Will the wildlife studies be available to landowners? a. We will include information about the biological study in the permit application. The Project team is also communicating with CPW and USFWS about the Project. Once the permit applications are accepted by the City and County, we will notify the landowners of the public hearing schedule. The permit application materials will be available for review on the jurisdictions’ websites. 9. Was a temporary construction easement considered instead of the 60-foot permanent easement? a. It was considered, but in the end, we want to be able to maintain our line in perpetuity. We will be maintaining this line for the next 50-80 years; we want permanent rights to work on this transmission line and not infringe on property owners to set up equipment and do work. 10. Did you say I might have to leave my house during helicopter activity? a. Yes. During some portions of the helicopter activity, particularly when helicopters are over impacted properties, it is recommended that we have people leave their homes. We would provide up to 72 hours of advanced notice to all homeowners. I don’t suspect it would be a long period of time, maybe an hour. Who will need to leave their home is dependent on the project’s Congested Area Plan which is filed with the FAA. The FAA will approve our Congested Area Plan as far as construction with helicopter. For safety reasons when the helicopter is lifting poles in and out of the construction area, we can’t have residents in their homes or in the streets. We have to clear the helicopter flight paths while we’re carrying those loads in case there was an emergency and the helicopter had to set the load down outside the plan. 11. Will the lines eventually be upsized beyond 115kV? a. The Xcel Planning group forecasts loads approximately 10 years in the future. We do not know what will be needed after 10 years, it will depend on how the area grows. We’d need to assess other economic factors at that time to see whether there’s any load growth that would require anything above 115kv. With a 10 year plan, we don’t see the need to upgrade it in the future, but after 10 years is unknown. 12. When will the additional landowners be contacted if their land is being considered for easement road access? a. We hope to have all offers out within the next two weeks. 13. What if our house is located on the property where there is a helicopter pad? a. All the helicopter pads will be located far enough away from houses, so folks won’t be impacted by continuous helicopter operations. We’ll be able to fly out and away from residential areas. 14. Will you 'share' your poles with other vendors, like internet providers? a. We do not have any agreements with this particular line, but we commonly collocate facilities on Xcel Energy lines. Vendors like internet providers go through a process where contact Xcel Energy to evaluate the addition of the new facilities and if it works out then the facilities are added onto the structures.

If a helicopter is located on the same property as a home, will that property owner need to be out of their house for the duration of helicopter use? a. We will get back to the specific landowner on this question. 16. Would ROW around the poles be considered for the 60-foot easement and the existing 30-foot easement be for the wires only? a. That would not work for transmission lines. There is a required clearance from the transmission wire in case it is blown by the wind. The worst case for that situation in terms of calculating that width occurs at the mid-span along the wires. So, the primary work that happens as far as construction equipment will occur at the structures. However, the middle of the span is where you have the most sag of the wires which means it’ll blow a lot more to the side and require the maximum amount of right-of-way right there in the middle based on the clearance from the wire. That’s why the additional clearance is needed along the line. 17. Why are permanent access easements needed? a. The current easements were established and the line was built in the 1940s. There are access easements and access improvements that are needed in order to construct and maintain the line. We are working with landowners to document all of that not only for construction, but also for long term maintenance of the line. 18. Is there a change in easement width just around the pole? Or is it the same easement width for the whole project? a. It is the same easement width for the entire length of the transmission line. 19. Will any of the routing studies be made publicly available? a. There will be information provided in the permit applications about the analysis. 20. Have there been any studies on the wildlife impacts of this project? a. Yes. We have reviewed the entire length of the existing and proposed rebuild route for any environmental concerns and will be working through that as we plan for construction. 21. What type of construction are you planning on roads to access temporary construction sites? a. There will be some upgrades to existing roads, and we will have to have some portions of the route cleared for equipment. I don’t believe there will be any new roads within the ROW, just what we need to get trucks in for construction. Using the helicopters for construction mitigates a lot of the road access impacts. Our crews can get to the pole sites on foot or on UTVs and pickup trucks, do all the digging by hand, climb the structures, set the new structures and take out the old structures with the helicopter. That precludes us from needing new access roads. 22. How tall will the new transmission structures be? a. The shortest pole will be 50-feet and the tallest pole will be 98 feet. The average pole will be about 65 feet. Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project Public Outreach Summary 23. What noise pollution or odors will emanate from the transmission line? a. There will not be any odor that emanates from the line. All power lines, no matter what their size, produce some amount of noise. We are required at the state level to have a minimum decibel level at the edge of the ROW. This 115kv line is on the low end of that noise requirement from the state. 24. Why is there an Xcel Energy line in Glenwood Springs? Where does my power come from? a. Glenwood Springs gets their power in a different way. The electric gird is a complex network of a lot of different independently owned and operated power generation facilities. Within that, transmission lines deliver the energy to the local communities. In Glenwood Springs, the transmission lines are owned by Xcel Energy and those lines are the highway that delivers the electricity to the Glenwood Springs electric department’s substation and distribution system. These distribution lines serve the local customers. Glenwood Springs purchases that wind power from Municipal Energy Agency of Nebraska (MEAN) and Xcel Energy infrastructure is the highway that moves that energy into your community. 25. How long will construction last? a. Construction will last for approximately 12 weeks total. That won’t be continuous helicopter operations or continuous disruptions. In some areas, we’ll have our crews hand digging holes and preparing the line. There will be a few weeks where crews are setting poles with helicopters and removing the poles. After helicopter operations are complete, wire stringing operations will occur; those won’t be impactful at all. 26. Will my trees be removed? a. We have determined that we don’t need to clear cut the right-of-way for this project. Pete and his team will be in touch with impacted property owners to talk through which trees will need to be removed or trimmed in order to maintain all of the required safety clearances necessary. Most of the trees that will be removed are elms and tall growing deciduous trees growing through fence lines. We will have to remove a few pinions and junipers around the base of the structures to allow for construction access. There is one property with landscaping and we’ve already discussed with that property owner what will need to be removed there. All impacted landowners will be contacted beforehand. 27. What alternatives were evaluated? a. As part of the routing evaluation, we examined about 15 different alternatives between the Glenwood Springs and the Mitchell Creek substations. That included different crossings of the Colorado river at various locations, including repurposing the existing crossing. As we moved east, we had concerns about proximity to highways, hot springs, and businesses. We used those as factors to help us determine that rebuilding along the existing route reduced the number of new impacts because that line was already there, as opposed to relocating the line to a new location for its 2 ¼ mile length. Glenwood Springs–Mitchell Creek Electric Transmission Line Rebuild Project Public Outreach Summary 28. Why does the ROW need to be expanded? a. From an engineering perspective, we calculate how much right-of-way is needed based on the electrified wires. When they get blown over to the side with wind, we need them to maintain certain clearance with trees, fences and signs. We don’t want any of those items within the right- of-way so we can maintain those clearances. We also need to construct and maintain the line, so we need to have enough room to set up equipment next to structures and stay enclosed within the right-of-way each time we set up, whether that is during construction, maintenance or during a storm issue. We want to make sure we have enough room and have access to our structures to be able to get into there and do the work we need. 29. Both the Colorado River and Tramway will be crossed with the Project. What are the impacts of this? a. Both the Colorado River and Tramway are currently crossed by the existing line. The rebuild route will cross both of these features in similar locations. We expect impacts to the Colorado River to be nothing since it’ll be in the same location. We have evaluated that crossing including any vegetation clearing needed in CDOT and highway right-of-way. The project team has also been talking to the owner of Adventure Caverns Park about the tramway crossing and the rebuild of that and we will continue to do so as the construction planning occurs. Since the existing line crosses the tram and the rebuild line will cross in a similar location, and no impacts are anticipated there. Construction work will be planned around the operation of the tramway in coordination with that landowner This page intentionally left blank.
