Pathway is a $ 1 . 7 to $ 2 billion investment to improve the state ' s electric grid and enable future renewable energy development around the state . Pathway will increase electric reliability , boost the regional economy , and create jobs during construction . P athway includes the installation of approximately 550 to 610 miles of new 345 - kilovolt ( kV ) double - circuit transmission line ; four new electric substations ; and expansion , equipment additions , or e quipment upgrades at four existing electric substations . P athway will be constructed in five segments , with an optional sixth segment , with each new or e xpanded electric substation serving as endpoints for the transmission line segments : • Fort St . Vrain — Canal Crossing ( Segment 1 ) • Canal Crossing — Goose Creek ( Segment 2 ) • Goose Creek — May Valley ( Segment 3 ) • May Valley — Tundra ( Segment 4 ) • Tundra — Harvest Mile ( Segment 5 ) • May Valley — Longhorn ( Extension ) In March 2021 , Xcel Energy filed a Certificate of Public Convenience and Necessity ( CPCN ) Application with the Colorado Public Utilities Commission ( CPUC ) describing the purpose , need , and public benefits of constructing Pathway . In February 2022 , the CPUC provided verbal approval , and in June 2022 , it provided written approval of the CPCN for Segments 1 - 5 , and conditional approval for the Extension based on a determination that Pathway is in the public interest . While the CPUC determines the need for Pathway , it does not determine the location of the components ; the location and land use permissions will be granted through easement negotiations with landowners and land use permits in the applicable jurisdictions where Pathway components will be located . P referred transmission line routes and substation sites for Pathway have been selected after completion of routing and siting studies , coordination with permitting entities , and conducting public outreach . P athway facilities proposed in Weld County subject to the 1041 Permit Application include 38 miles of new 345 - kV double - circuit electric transmission line in new right - of - way ( ROW ) and a 67 . 6 - acre laydown area ( referred to as the Cervi Yard ) . The proposed route in Weld County is generally located in central Weld County in an east - west direction .

U SR Use by Special Review Xcel Energy Public Service Company of Colorado , a Colorado corporation conducting business as Xcel Energy COLORADO ' S POWER PATHWAY 1 1 INTRODUCTION P ublic Service Company of Colorado , a Colorado corporation conducting business as Xcel Energy ( Xcel Energy ) , proposes to construct , maintain , and operate Colorado ' s P ower Pathway ( Pathway ) in eastern Colorado . Xcel Energy is submitting this 1041 P ermit Application ( Application ) for a permit to locate and construct Major Facilities of a P ublic Utility or Public Agency ( 1041 permit ) , pursuant to the Weld County , Colorado , Chapter 21 , Article III , Division 3 , Permit Program for Site Selection and Construction of a Major Facility of a Public Utility ( Weld County 2023a ) . The Application addresses each section in the Weld County § 1041 Requirements as noted in the headings and tables throughout this Application . Like information is grouped throughout the Application . As a result , this Application does not follow the exact subsection order in the Weld County 1041 Regulations . P athway is a $ 1 . 7 to $ 2 billion investment proposed by Xcel Energy to improve the state ' s electric grid and enable future renewable energy development around the state . P athway will ensure safe , reliable , and economical electric service to the public , boost the regional economy , and create jobs during its construction . Pathway includes : • Installation of approximately 550 to 610 miles of new 345 - kilovolt ( kV ) double - circuit transmission line in 12 to 14 counties ; • Construction of up to four new electric substations ( Canal Crossing , Goose Creek , May Valley , and Longhorn ) ; and • Expansion , equipment additions , or equipment upgrades at four existing electric substations ( Fort St . Vrain , Pawnee , Harvest Mile , and Tundra ) . P athway will be constructed in five segments , with an optional sixth segment ( Figure 1 ) , with each new or expanded electric substation serving as endpoints for the transmission line segments : • Fort St . Vrain — Canal Crossing ( Segment 1 ) • Canal Crossing — Goose Creek ( Segment 2 ) • Goose Creek — May Valley ( Segment 3 ) • May Valley — Tundra ( Segment 4 ) • Tundra — Harvest Mile ( Segment 5 ) • May Valley — Longhorn ( Extension ) A fifth new substation ( Sandstone Substation ) may be constructed near the western end of Segment 4 and southern end of Segment 5 if an additional substation is determined COLORADO ' S POWER PATHWAY 2 to be necessary in this area to provide a location for future generation interconnections . A decision regarding the need for this substation will likely be made in 2023 . The estimated length of each transmission line segment and location of each substation is outlined in Table 1 . I ! t .

The Vicinity Map ( Attachment A ) shows all Pathway facilities proposed in unincorporated Weld County that are subject to the 1041 , Use by Special Review , and Site Plan Review application processes . Pathway facilities subject to this 1041 Application include 38 miles of new 345 - kV double - circuit electric transmission line in new right - of - way ( ROW ) and a 67 . 6 - acre laydown area ( referred to as the Cervi Yard ) . Pathway facilities subject to the Use by Special Review application include 9 . 1 miles of new 345 - 1cV double - circuit transmission line within the ROW permitted under Use By Special Review ( USR ) - 1236 ; the relocation of 4 . 5 miles of existing 230 - kV electric transmission line into new ROW and the relocation of 4 . 5 miles of existing 230 - kV electric transmission line within the USR - 1236 ROW to accommodate engineering requirements for Pathway crossing of the existing transmission lines within the USR - 1236 ROW ; and a 59 . 4 - acre laydown area ( referred to as the Sarchet Yard ) . Pathway facilities subject to the Site Plan Review application include equipment additions to Xcel Energy ' s existing Fort St . Vrain Substation owned by PSCo . COLORADO ' S POWER PATHWAY 4 Note that Pathway is an addition to Colorado ' s backbone transmission system and does not provide distribution electric service ; as such , this Application does not address project - specific details that apply for developments or direct utility service projects . The Eastern Plains region of Colorado is one of the nation ' s best areas for wind and solar energy generation , but it does not currently have a network transmission system that can integrate these new generation resources into the state ' s interconnected grid system , which is needed to meet Colorado ' s clean energy goals . Pathway will support Xcel Energy ' s Clean Energy Plan ( Xcel Energy 2021 ) that is estimated to deliver as much as an 85 percent reduction in carbon dioxide emissions by 2030 and add approximately 5 , 000 megawatts of new wind , solar , and other resources . Pathway will help to meet the state ' s growing electricity needs , improve safety , reliability , and affordability , and enable the transition to clean energy . Pathway will allow developers of energy generation projects to interconnect energy resources located in the areas of the state that are underserved by backbone transmission lines and allow Xcel Energy to deliver energy to electric customers . In March 2021 , Xcel Energy filed a Certificate of Public Convenience and Necessity ( CPCN ) application with the Colorado Public Utilities Commission ( CPUC ) describing the purpose , need , and public benefits of constructing Pathway . In February 2022 , the CPUC provided verbal approval , and in June 2022 , CPUC provided written approval of the CPCN for Segments 1 - 5 , and conditional approval for the Extension , based on a determination that Pathway is in the public interest . While the CPUC determines a public need for Pathway , it does not approve the location of specific project facilities . The location and land use approvals will be through easement negotiations with landowners and the land use approval process in the applicable jurisdictions where the Pathway facilities will be located . 1 . 1 ESTIMATED PATHWAY SCHEDULL The estimated approval , construction , and in - service schedule for Pathway facilities is shown in Figure 2 . Many variables factor into the schedule for projects of this magnitude . The construction schedule is contingent on acquiring all necessary land rights and permits . Pathway will be constructed and brought in - service in phases . The estimated construction timeline for each segment and related substation , and anticipated in - service dates are shown in Table 2 and Figure 2 . Transmission line Segment 1 will be completed in 2026 assuming the required approvals are obtained .

These meetings were held virtually due to restrictions on large gatherings due to COVID - 19 . • In June through September 2021 , Pathway representatives met with jurisdictions within Pathways Study Areas to discuss Pathway and receive feedback . Pathway representatives met with Weld County representatives on June 17 , 2021 . • In September 2021 , two virtual routing and siting meetings were held for the public to learn about the progress made on Pathway , including the development of focus areas for identification of transmission line links and substation sites . These meetings were held virtually due to restrictions on large gatherings due to COVID - 19 . • In October and November 2021 , 15 in - person public open houses were held to gather public feedback on the preliminary transmission links . A public open house was held in Platteville on November 1 , 2021 . • In January through March 2022 , 15 in - person open houses were held to present the preferred route for Segments 1 , 2 , 3 , 4 , and the Extension and to present additional preliminary transmission links for Segment 5 . A public open house was held in Platteville on January 24 , 2022 . • In May 2022 , four in - person open houses were held to gather additional public feedback on the preliminary transmission links and partial preferred route for Segment 5 . • In August 2022 , two in - person open houses were held in the Eastern Review Area , an area further east from the Segment 5 preliminary transmission links and partial preferred route , to gather feedback from landowners in that area about potential additional route options . COLORADO ' S POWER PATHWAY 8 1 . 2 . b ransm - ss ' on L ' ne Routing & Substation Siting Studies Routing a new transmission line and siting a substation require a comprehensive review and analysis of factors and criteria including , but not limited to , electric system planning , engineering , environmental and cultural resources , land use , regulatory requirements , land rights , stakeholder input , and public and worker safety . As shown in Figure 3 , the five - step routing and siting process assesses constraints and opportunities between segment endpoints to ultimately identify the preferred route location for the transmission line and the preferred locations for new substation sites . The process is described in detail in the routing and siting studies for each segment of Pathway . The Routing and Siting Study for Segment 1 is attached to this Application as Attachment B . The other routing and siting studies are not provided because they do not involve transmission lines or substations within Weld County .

Outreach was conducted with each jurisdiction crossed by Pathway to solicit feedback and discuss potential permits that may be required . Multiple Colorado statutory provisions and local government land use plans and controls apply to Pathway , including approval of a CPCN from the CPUC ; notice , consultation , and permit approvals from counties and municipalities , and notice to owners of a mineral estate associated with the substation sites . All necessary land use , environmental , and construction permits , approvals and authorizations will be obtained prior to the start of and during construction as required and may include but are not limited to major land use permits , ROW permits , road use agreements , access permits , oversize / overweight permits , grading permits , and stormwater permits . Xcel Energy anticipates avoiding impacts to jurisdictional waters of the U . S . ( WOTUS ) in Weld County and therefore does not anticipate that Pathway facilities in the County will require a Nationwide Permit 57 or other U . S . Army Corps of Engineers permitting under the Federal Clean Water Act , Section 404 . The regulatory requirements identified by Xcel Energy are described in the response to Supplemental Question 15 . b . i of the 1041 Questionnaire ( Attachment C ) . 1 . 4 DESCR PT ON OF FAC L Y This Application addresses only the portion of the Pathway transmission line and other related facilities subject to the Application located within Weld County ( see Attachment A , Vicinity Map ) . Pathway land use permitting is occurring concurrently with El Paso , Elbert , Arapahoe , Lincoln , and Pueblo counties and the City of Aurora for the portions of Segments 4 and 5 that occur in those jurisdictions . Coordination is ongoing with additional jurisdictions for other Segments . This Application package was prepared per the requirements of the Weld County 1041 Regulations . The Application also was prepared based on direction provided by Weld County representatives during the Pre - Application Conference held on October 5 , 2022 . Pathway facilities proposed in Weld County subject to this Application include 34 . 3 miles of 345 - kV double - circuit transmission line in Segment 1 ( Attachment A ) . The proposed transmission line route in Weld County is generally located in the area between Platteville and Wiggins , oriented in a west to east direction . The proposed route crosses Interstate Highway 76 east of Roggen as shown on Attachment A . The COLORADO ' S POWER PATHWAY 11 following sections describe the Pathway transmission line facilities within Weld County jurisdiction subject to this Application . 1 . 4 . a Transmission L ' ne The new 345 - kV double circuit transmission line will be constructed using steel poles . A single pole will be used for most transmission pole locations ; however , two transmission poles will be required for certain high - loading transmission pole locations such as at angle locations where the line changes direction . Each transmission pole will be placed on a concrete foundation . Voltage , conductor sag , pole type , terrain , length of span between transmission poles , and minimum clearances of existing buildings influence the necessary height of transmission pole . The transmission poles will be weathering steel and a brown or rust color . The anticipated physical characteristics of a double - circuit pole are summarized in Table 3 , and a representative transmission pole with line is shown in Figure 4 . Table 3 : Typical 345 - kV Double Circuit Transmission Line Characteristics Characteristic Anticipated Design Typical height 105 - 140 feet ( transmission poles will not exceed 199 - foot maximum height ) Right - of - way 150 feet in total width , 75 feet on either side of the centerline Span length Typically 950 feet between transmission poles Material / color Weathering steel , brown or rust color Clearance Maintain all clearances as required by National Electric Safety Code COLORADO ' S POWER PATHWAY 12 ' `4, 0 , \, SHIELD WIRE ` , \ \ k. , • :- r INSULATOR 1-""••,, ,..\ 1 CONDUCTOR \\ \ , \ ,.�� , 1 �j • -.� • , ` CT/ II 1 , it ' II� TRANSMISSION frl POLE 4 411 _ p - • ROW 050 feet ) Figure 4 : Typical Transmission Pole Configuration ( Illustrative ) COLORADO ' S POWER PATHWAY 13 1 . 4 . b ransm - ss ' on Line Access Construction access roads will allow construction crews and vehicles to access transmission pole locations and temporary construction areas ( TCAs ; described below ) . Traffic controls may be required near TCAs during construction to ensure the safety of crews and the travelling public . Where practicable , existing public roads and private roads will be utilized during Pathway construction , maintenance , and operation . Some private roads may require improvements and some new access roads will need to be constructed to accommodate construction equipment and long - term maintenance of the transmission line . Where road improvements are needed , Xcel Energy will acquire any necessary grading , stormwater , and erosion control permits and comply with permit requirements . Xcel Energy will acquire access easements where necessary access routes traverse private property . Some access routes may remain post - construction to maintain access to transmission lines for operation and maintenance activities . 1 . 4 . c Temporary Construct ' on Areas TCAs will be used during construction to stage construction equipment and materials including construction trailers , cranes , and transmission poles . Some TCAs may require grading to level out the area for equipment placement and materials storage . TCAs are also necessary when stringing the conductor wire . The proposed TCAs needed for Pathway are represented in the 1041 USR Map ( Attachment D ) . Permits will be obtained for TCAs as required . At the end of each construction phase , all equipment will be removed from the TCAs for that construction phase . No proposed improvements at the TCAs will be permanent , and TCAs will be restored in a manner generally similar to preconstruction conditions . TCA locations are shown in Attachment D . Additional details about TCAs are discussed in the following sections . 1 . 4 . c . 1 Staging/Laydown Areas The Cervi Yard is 67 . 6 acres and is located in Parcel Number 121933000011 in the A ( Agricultural ) Zone District . The Cervi Yard is located south of the 1 - 76 Frontage Road and northeast of WCR 75 . 5 ( see Attachment A , Vicinity Map ) . The Cervi Yard will have two entrances along the 1 - 76 Frontage Road . The Cervi Yard will consist of a sub - base gravel surface pad that supports three 40 - foot - by - 20 - foot Conex containers , three 30 - yard - by - 10 - yard dumpsters , one 12 - foot - by - 56 - foot construction trailer , one water tank , and parking for construction worker vehicles COLORADO ' S POWER PATHWAY 14 and equipment . A temporary 4 - foot - high barbed wire security fence will be placed around the gravel surfaced pad . An infiltration pond will be placed west of the Cervi Yard gravel site pad to collect runoff from the site and prevent any flooding in the pad . Stormwater best management practices will be used to control stormwater runoff and reduce the spread of pollutants . Following construction , all equipment will be removed and the Cervi Yard will be restored . The perimeter fence and infiltration pond also will be removed following construction . The Cervi Yard Drainage Report and Site Plan is provided as Attachment E . 1 . 4 . c . 2 Conductor Stringing Areas TCAs will be used for stringing the conductor wire . The locations and use of TCAs for this function are required at specific angles to ensure the conductor wire is pulled in line with the transmission poles , thereby limiting the strain on the poles . In addition , TCAs may be used adjacent to public roadways for temporary guarding / protecting of the roadway during stringing of the new transmission line . Typically , these temporary guard sites will be restored following construction , as described above . 1 . 4 . d Areas for Other Construction Activities Construction contractors may utilize temporary concrete batch plants during construction to produce concrete needed for transmission pole foundations . A concrete batch plant consists of the various equipment and materials needed to make concrete . Concrete batch plant equipment typically includes mixers , batchers , conveyors , stackers , bins , heaters , chillers , silos , controls , and dust collectors . Concrete batch plants can be either stationary or mobile . The numbers , locations , and types of concrete batch plants will be determined by the construction contractor and will be a permitted accessory use pursuant to this Application that will be reviewed and approved administratively by County staff as described above and subject to local operational requirements prior to construction . The construction contractor will obtain and meet the requirements related to a Concrete Batch Plant Air Pollutant Emissions Notice ( APEN ) with the Colorado Department of Public Health and Environment ( CDPHE ) if necessary . Construction contractors also will use TCAs to store water trucks , traffic control items , and best management practice ( BMP ) materials . Water will be used in concrete production , dust suppression , and compaction activities . Traffic control will be implemented where required for the safety of the crews and the traveling public . BMPs will be installed to meet stormwater , grading , and erosion control requirements . COLORADO ' S POWER PATHWAY 15 Construction contractors will work with the appropriate jurisdictions to obtain and follow all related construction permits . TCAs are shown in Attachment D . 1 . 4 . e Construction Process 1 . 4 . e . 1 Construction Phases Construction of the transmission line is expected to occur in phases that generally include the following : construction access and vegetation clearing , installation of BMPs , equipment mobilization and material delivery , foundation construction , transmission pole placement and installation , conductor wire stringing and electrical equipment installation , and land restoration . Construction access road improvements , grading , and setup of TCAs , along with vegetation work , will be conducted prior to construction of the transmission line . Proposed access roads will allow construction crews and vehicles to access transmission pole locations and TCAs . Vegetation management within the ROW will be required prior to , or in conjunction with , construction . Trees and tall vegetation growing within or near the Pathway 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 herbicides to ensure safe operations . The extent of this work will vary along the transmission line depending on level of vegetation encroachment and additional ROW needs . 1 . 4 . e . 2 Transmission Line Construction Once the pre - construction preparation work has been completed , work on the transmission lines will begin . The new transmission pole foundations will consist of concrete reinforced with steel that can range in diameter and depth based upon the subsurface conditions . Construction crews will begin drilling for transmission pole foundations . Reinforced concrete drilled pier foundations typically range from 6 to 9 feet in diameter and are drilled 20 to 40 feet deep . Once construction crews have drilled the hole for the new transmission pole , the foundation is installed , and the hole is backfilled . Transmission poles will be placed using cranes . Crane installation will involve first hauling the transmission pole pieces to the location and then assembling the transmission poles at the installation locations and setting them with the crane . Once assembled , transmission poles will be transported by truck to installation locations and cranes will lift the transmission poles into place . COLORADO ' S POWER PATHWAY 16 Once all the transmission poles are in place , the conductor wire and optical ground wire are strung using a temporary pulley system attached to the insulators . Conductor is pulled from one transmission pole to the next through a pulley system temporarily placed on the transmission pole . After a section of conductor is pulled through a series of transmission poles , the conductor is attached to insulators , which are attached to the transmission pole and the pulleys are removed . Trucks , heavy equipment , and helicopters are used in this process . Federal Aviation Administration ( FAA ) safety requirements may require residences near the transmission line to evacuate during helicopter use . 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 . Other equipment including bird diverters , spacers , and anti - galloping devices are also installed as needed . TCAs will be located at specific angles to ensure the conductor wire is pulled in line with the transmission poles , remaining in alignment . 1ate . 3 Construction Staffing , Vehicles , and Equipment The first workers , vehicles , and equipment to mobilize for Pathway will conduct investigative fieldwork and prepare work areas for construction . Prior to construction and during the Pathway planning and design stages , soil borings are taken to understand the sub - surface conditions where Pathway facilities will be built . Geotechnical borings are taken using bore drill rigs . Vegetation clearing may be conducted to meet requirements for conductor clearances , minimize potential ignition sources , and to provide access within the ROW . Tree clearing and other vegetation removal is completed with both manual and mechanized equipment and will take place on the identified access route and the area within the easement . Matting is utilized as needed in wet or soft areas to prevent compaction , minimize soil disturbance , and improve site safety . It is anticipated that one 12 - hour shift per day ( Monday through Saturday ) will be worked during transmission line construction , but additional hours may be required . This will be during daylight hours , early morning to early evening . If additional hours are anticipated for shift work , a 24 - hour work permit will be obtained from Weld County . The maximum number of construction workers on site at any one time at any work area will be approximately 60 to 80 for the new transmission line when all phases are active . Transmission line construction is expected to be completed in phases over the duration of the construction schedule for each Pathway segment . The transmission line will not have any permanent on - site employees . Upon completion , Pathway will be operated and monitored remotely 24 hours a day , 7 days a week , 365 days a year to provide safe and reliable electric service . The transmission line will be inspected regularly ( at least annually ) to look for the following : COLORADO ' S POWER PATHWAY 17 • Non - compatible vegetation and hazards within the ROW . • Equipment needing repair or replacement . • ROW encroachments , which can be hazardous to safety and reliable operations . • Anything that might jeopardize safe , reliable operation of the power line . • Operations and maintenance staff must visit the ROW for these inspections , but visits typically are minimal , and landowners will be contacted prior to on - site inspections or maintenance . However , in cases of emergency , advanced contact may not be possible . It is anticipated that an average of 20 to 30 trucks per day will be utilized during the construction of the transmission line for crews , spotting materials , framing poles , and erecting poles . Concrete truck deliveries will be made daily when the foundations and piers are being constructed . Multiple deliveries of cement ( up to 20 to 30 per day ) will be required daily at certain stages of construction . Materials will be delivered to the Cervi Yard at the onset of construction . An additional 10 to 15 trucks will be needed to deliver steel poles , conductor , anchor bolts , and foundation materials daily to work areas . The impact to local public roads will vary day - by - day as the construction moves along the route . A crane , drill rig , concrete truck , boom trucks , trailers , transmission poles , steel casing , and rebar cages are equipment and materials that will be moved into the site for construction . The transmission poles are delivered by truck and assembled at the foundation site and set in place with the use of cranes and other heavy equipment . Trucks , heavy equipment and sometimes helicopters are used to install conductor wire after all transmission poles are erected in an area . To mitigate any potential impacts to Weld County roads , Traffic Control Plans will be prepared and followed during construction .

Additional information on design and hazard avoidance and mitigation is provided in the 1041 Questionnaire response to Supplemental Question 3 ( Attachment C ) . (2) The natural and socio - economic environment of this County will be protected and enhanced . P athway facilities are sited to minimize impacts to natural resources as described in the responses to Supplemental Questions 4 and 15 of the 1041 Questionnaire ( Attachment C ) . Pathway will enhance the socio - economic environment in Weld County during the construction period via increased revenue to local businesses and social services . Project construction will require contract labor , and provide local jurisdictions and host communities with additional tax revenues and potential employment opportunities . Once in operation , Pathway may facilitate ongoing job opportunities and tax revenue in clean energy ( wind , solar , etc . ) that ultimately interconnect to Pathway . Additionally , generation developers will have the opportunity to build projects that otherwise were infeasible due to lack of transmission access to market and / or transmission constraints . These generation projects may provide other additional economic development through increased jobs associated with construction and local tax - based revenue associated with land usage , and payments to existing landowners . (3) All reasonable alternatives to the proposed action , including use of existing rights - of- way and joint use of rights - of- way wherever uses are compatible , have been adequately assessed and the proposed action is compatible with and represents the best interests of the people of the County and represents a fair and reasonable utilization of resources in the impact area . The design and need of Pathway have been approved by the CPUC and represents the use and application of best technology and industry standards for transmission and transformation of electric energy . Routing and siting studies were prepared to review and consider reasonable routing and siting alternatives for the new major electrical facilities ( pursuant to Colorado Revised Statute [ CRS ] 29 - 20 - 108 ( 4 ) ( a ) and ( b ) ) ( Attachment B ) . The Segment 1 : Fort St . Vrain — Canal Crossing Routing and Siting S tudy is included as Attachment B . Public open house meetings were conducted virtually in June 2021 and September 2021 and in Weld County in November 2021 and January 2022 to inform the public and key stakeholders about Pathway , gather feedback , and address questions and concerns . The analyses of alternatives evaluated in the routing and siting studies and feedback from public and key stakeholders were used to determine the proposed preferred locations for Pathway facilities in Weld County . The portions of Pathway in Weld County as described in this Application XCEL ENERGY 30 represent the best interests of the people in the County and the best utilization of resources in the impact area . ( 4) A satisfactory program to mitigate and minimize adverse impacts has been presented . P athway will mitigate and minimize adverse impacts as described in the responses to P upplemental Question 15 of the 1041 Questionnaire ( Attachment C ) . ( 5) The nature and location or expansion of the facility complies with all applicable provisions of the master plan of this County, and other applicable regional, metropolitan , state , and national plans . P athway is not inconsistent with any adopted county , regional , metropolitan , or state master plans or comprehensive plans . An analysis of Pathway consistency with the Weld County Comprehensive Plan ( Weld County , Colorado , Charter and County Code Chapter 22 , Comprehensive Plan ; Weld County 2023a ) is provided as Attachment K . P athway is sited within " Agriculture " zone districts within Weld County and is compatible with agricultural use . The transmission line alignment spans existing irrigation ditches and pivot irrigation in fields to minimize impact to existing agricultural operations ( Attachment P ) . Aside from the transmission pole foundation footprint , areas under and around Pathway facilities can continue to be used for agricultural operations after construction has been completed . Regarding transportation , Pathway will mitigate impacts to Weld County roads through use of BMPs and traffic control during construction , and post - construction restoration . ( 6) The nature and location or expansion of the facility does not unduly or unreasonably impact existing community services . P athway will not negatively affect the existing emergency health care facilities , social services , or law enforcement services as described in the response to Supplemental Question 4 of the 1041 Questionnaire ( Attachment C ) . P athway will not cause a significant change in land use in the immediate area . Current uses adjacent to Pathway facilities will be able to continue mainly unchanged after construction of Pathway thereby preserving desirable community and rural patterns which exist . Following construction , agricultural activities along the transmission line route can continue outside of the area occupied by the transmission poles . ( 7) The nature and location or expansion of the facility will not create an expansion of the demand for government services beyond the reasonable capacity of the community or region to provide such services , as determined by the Board of County Commissioners . XCEL ENERGY 31 P athway will not require additional local government services beyond those currently provided in the area . Pathway creates no additional demand for transportation infrastructure , educational facilities , housing , water ( other than water for construction ) , wastewater treatment , or public transportation . As described in the response to Supplemental Question 10 of the 1041 Questionnaire ( Attachment C ) , it is anticipated that an average of 20 to 30 trucks per day will be utilized during the construction of the transmission line for crews , spotting materials , framing poles , and erecting poles . Concrete truck deliveries will be made daily when the foundations and piers are being constructed . Multiple deliveries of cement ( up to 20 to 30 per day ) will be required daily at certain stages of construction . Materials will be delivered to the Cervi Yard at the onset of construction . An additional 10 to 15 trucks will be needed to deliver steel poles , conductor , anchor bolts , and foundation materials daily to work areas . The impact to local roads will vary day - by - day as construction moves along the route . To mitigate any potential impacts to Weld County roads , Traffic Control P lans will be prepared and followed during construction . ( 8) The facility site or expansion area is not in an area with general meteorological and climatological conditions which would unreasonably interfere with or obstruct normal operations and maintenance . P athway is not located in an area with meteorological or climatological conditions that would unreasonably interfere with normal operations and maintenance . Pathway is designed to minimize the risks from natural hazards such as high winds and floods . ( 9) The nature and location of the facility or expansion will not adversely affect the water rights of any upstream , downstream , or agricultural users , adjacent communities or other water users . P athway will not require water rights for construction or operation and will not affect existing water rights . ( 10) Adequate water supplies are available for facility needs . Water to be used during construction will be obtained from a local , permitted source . P athway will not require water use during operation . 01 ) The nature and location of the facility or expansion will not unduly interfere with any existing easements for or rights - of-- way, for other utilities , canals , mineral claims , or roads . As part of the land rights acquisition process , Xcel Energy will identify any existing easements or ROWs for other utilities , canals , mineral claims , or roads and will not XCEL ENERGY 32 cause any undue interference with existing easements or ROWs during construction and operation of Pathway . ( 12) Adequate electric , gas , telephone , water, sewage , and other utilities exist or shall be developed to service the site . P athway facilities will not require gas , telephone , water , sewage , or other utility service in Weld County . ( 13) The nature and location for expansion of the facility will not interfere with any significant wildlife habitat or adversely affect any endangered wildlife species , unique natural resource or historic landmark within the impact area . S ensitive natural resources and wildlife interests were considered in identifying the preferred location for the transmission line to minimize potential interference from P athway facilities . In addition , Xcel Energy has communicated with Colorado Parks and Wildlife and U . S . Fish and Wildlife representatives regarding Pathway and will continue to coordinate with them throughout design and construction of Pathway including compliance with applicable regulatory requirements . Pathway will not affect unique natural resources or historic landmarks in Weld County . ( 14) The nature and location or expansion of the facility, including expected growth and development related to the operation and provision of service , will not significantly deteriorate water or air quality in the impact area . Construction activities will be performed by methods that prevent entrance or accidental spillage of solid matter , contaminants , debris , or other pollutants and wastes into flowing streams or dry watercourses , lakes , and underground water sources . Activities will follow BMPs for the management of wastes to avoid and minimize effects from potential spills or other releases to the environment . Construction of the transmission line will not create runoff in excess of previous site levels and will not change existing topography or adversely affect drainage . No alteration in the pattern or intensity of surface drainage will occur as a result of construction or operation of the transmission line . Xcel Energy will comply with permit application requirements , Weld County standards , and construction protocols to ensure that Pathway does not affect water quality . Prior to construction , a Storm Water Permit for Construction Activities will be obtained from CDPHE , and a site - specific Stormwater Management Plan ( SWMP ) will be developed . S hort - term effects to air quality are anticipated from a temporary increase in construction vehicles , which may increase fumes and fugitive dust , construction equipment exhaust ( fumes ) , and clearing and preparing areas for construction ( dust ) . XCEL ENERGY 33 The short - term effects are not expected to cause a public nuisance . If a nuisance arises during construction , the nuisance will be mitigated in coordination with Weld County . Xcel Energy will apply for a CDPHE APEN for land development prior to construction and follow state standards to control the release of fugitive dust related to construction , if necessary . The APEN will be required for a disturbance greater than 25 contiguous acres and land development activities longer than 6 months . ( 15) The geological and topographic features of the site are adequate for all construction , clearing , grading, drainage , vegetation , and other needs of the facility construction or expansion . Xcel Energy will conduct geotechnical investigations to identify potential geologic hazards along the transmission line alignment . Xcel Energy also has institutional knowledge of the area because Xcel Energy owns the existing Fort St . Vrain Substation facilities immediately adjacent to the existing area that will be utilized . Based upon investigations to date and knowledge of the area , Xcel Energy does not believe there are significant risks from geological hazards associated with Pathway . The landscape along the Pathway facilities in Weld County is flat with little variation in topography . Pathway will not significantly change the existing topography . The transmission line is designed to conform with existing topography . ( 16) The existing water quality of affected state waters will not be degraded below state and federal standards or established baseline levels . Construction activities will be performed by methods that prevent entrance or accidental spillage of solid matter , contaminants , debris , and other pollutants and wastes into flowing streams or dry watercourses , lakes , and underground water sources . Activities will follow BMPs for the management of wastes to avoid and minimize effects from potential spills or other releases to the environment . Water quality will be maintained during construction through BMPs and the site - specific SWMP . Pathway will not impact the quantity or quality of water flowing off of the site . Where feasible , the transmission line will span streams and waterways that cross the corridor and impacts to state wafters will be avoided to the extent practicable . ( 17) The proposed project will not have a significantly adverse net effect on the capacities or functioning of streams , lakes and reservoirs in the impact area , nor on the permeability, volume , recharge capability, and depth of aquifers in the impact area . XCEL ENERGY 34 The transmission line will span or avoid any wetlands , streams , lakes , and reservoirs as feasible . Water quality will be maintained during construction through BMPs and the site - specific SWMP . Pathway will not impact aquifers . ( 18) The benefits of the proposed developments outweigh the losses of any natural resources or reduction of productivity of agricultural lands as a result of the proposed development . Construction and operation of Pathway will result in minimal permanent impacts to natural resources or agricultural lands . Aside from the transmission pole foundation footprint , areas under and around Pathway facilities can continue to be used for agricultural operations after construction has been completed . The development of Pathway in Weld County is anticipated to provide local economic benefits during construction and potential long - term economic benefits should new generation resources be developed in the area . Pathway will also improve the state ' s electric reliability , thereby benefiting all consumers in Colorado . ( 19) The applicant has obtained or will obtain all property rights , permits and approvals necessary for the proposed project, including surface , mineral and water rights and easements for drainage , disposal, utilities , access , etc . If the applicant has not obtained all necessary property rights , permits and approvals , the Board may, at its discretion , grant the permit conditioned upon completion of the acquisition of such rights prior to issuance of a zoning or building permit by the County . Xcel Energy will acquire all applicable permits and approvals necessary for Pathway ahead of conducting any work subject to such permits and approvals . Xcel Energy will also acquire possession of all necessary property interests in a parcel before initiating construction or other work associated with such interests . ( 20) The proposed project (nonlinear facilities) will not present an unreasonable risk of exposure to or release of toxic or hazardous substances within the impact area . The determination of effects of the project shall include the following considerations : (a) The means by which outdoor storage facilities for fuel, raw materials , equipment and related items are adequately enclosed by a fence or wall . No hazardous materials will be used , stored , or generated on site of Pathway facilities . Chemicals that may be used during construction and operation are those found in diesel fuel , gasoline , coolant ( ethylene glycol ) , and lubricants in machinery , and such chemicals , if any , will be kept within the TCAs pursuant to appropriate storage protocols and applicable regulatory controls . XCEL ENERGY 35 (b) The likelihood of hazardous materials or wastes being moved off the site by natural causes or forces . No hazardous materials will be permanently used , stored , or generated on site of Pathways facilities . Hazardous materials used during construction and operation will be used and disposed of in compliance with applicable federal , state , and local regulations . Enclosed containment will be provided for trash disposal . Construction waste , including trash and litter , garbage , other solid waste , petroleum products , and other potentially hazardous materials , will be removed and taken to a disposal facility authorized to accept such materials . Construction , operation , and maintenance activities will comply with applicable federal , state , and local laws and regulations regarding the use of hazardous substances . Construction activities will be performed using methods that prevent entrance or accidental spillage of solid matter , contaminants , debris , or other pollutants and wastes into flowing streams or dry watercourses , lakes , and underground water sources . Activities will follow BMPs for the management of wastes to avoid and minimize effects from potential spills or other releases to the environment . (c) Containment of inflammable or explosive liquids , solids or gases . Chemicals that may be used during construction and operation would be stored within TCAs , as set forth in Criterion ( 20 ) ( a ) above . Measures to contain or control any spill that may occur and to contact appropriate emergency offices and personnel will be formulated and designed in accordance with applicable federal , state , and local requirements . ( 21 ) The scope and nature of the proposed project will not unnecessarily duplicate existing services within the County. The scope of Pathway does not duplicate any existing services within Weld County . Pathway fills a need for a network transmission line facility to connect demand centers with areas of the state best situated for wind and solar generation projects . ( 22) If the purpose and need for the proposed project are to meet the needs of an increasing population within the County, area and community development and population trends demonstrate clearly a need for such development . The purpose and need for Pathway are not to meet the needs of an increasing population within Weld County but are primarily to meet the state ' s growing electricity needs ; improve electric safety , reliability and affordability ; and enable the transition to clean energy .

The capacities of storage tanks and types of petroleum derivative to be stored . No petroleum derivative will be stored , and no storage tanks will be needed . e . Corridor locations . The proposed transmission line corridor subject to 1041 Application is shown on Vicinity Map in Attachment A . The corridor subject to this 1041 Application starts approximately 0 . 9 mile east of Weld County Road 33 , travels to the north for approximately 0 . 5 mile to Weld County Road 28 , then east along Weld County Road 28 for approximately 2 miles to Weld County Road 39 . The corridor continues south along Weld County Road 39 for approximately 0 . 5 mile to Weld County Road 26 , then east along Weld County Road 26 for approximately 8 miles . The corridor continues southeast for approximately 5 . 5 miles COLORADO ' S POWER PATHWAY 2 to the Interstate 76 ( I - 76 ) / US - 6 ( US - 6 ) right - of - way ( ROW ) and continues east for approximately 6 miles where the transmission line corridor crosses the I - 76 / US - 6 ROW . The corridor then generally parallels the Burlington Northern Santa Fe Railroad ROW for approximately 9 . 5 miles to the corridor endpoint . f. Service area . P athway is an addition to Colorado ' s backbone transmission system and does not provide distribution electric service ; as such , this 1041 Application does not address project - specific details that apply for developments or direct utility service projects . g . Resource area (e . g . , source of power being generated or transmitted) . P athway does not connect to a specific power source . Facilities in Weld County are part of the larger Pathway that creates a transmission " loop " to provide additional transmission capacity . Pathway is being routed through some of the best wind and solar resource zones in Colorado . New renewable energy generation is anticipated to be developed in these zones . The location of these new generation resources is currently unknown until Xcel Energy ' s Electric Resource Plan process has been completed . Generally , new generation resources are expected to interconnect at substations located at segment endpoints . h . Applicable support facilities (e . g . , pollution control, parking areas , landscaping , etc . ) to be provided . As described in the response to review criteria 21 - 3 - 340 ( A ) ( 14 ) in Section 5 of this 1041 Application , best management practices ( BMPs ) will be used during construction to control sediment and runoff from work areas . Compliance with applicable federal , state and county construction and waste management procedures will prevent accidental spills or runoff of sediment or contaminants to waterbodies or groundwater . P athway is not anticipated to generate pollution during operations and maintenance and will not require permanent pollution control equipment . A Stormwater Management Plan ( SWMP ) will be created , and stormwater management features incorporated into the design as necessary . No public parking spaces are needed for Pathway , and access drives from nearby roads for construction and maintenance have been incorporated into the transmission line design . Access to the transmission poles will be off nearby roads to the transmission line ROW . Once construction has been completed , areas not needed for operations and maintenance will be reclaimed in a manner generally similar to their condition prior to COLORADO ' S POWER PATHWAY 3 construction or as may be provided for in private agreements ( including by re - seeding in accordance with Xcel Energy ' s vegetation management standards and SWMP ) . 2 . Describe the projected development schedule . Specify where applicable : a . Estimated maximum number of employees , number of shifts and employees per shift during the construction , operation and maintenance phases of the project . It is anticipated that one 12 - hour shift per day ( Monday through Saturday ) will be worked during transmission line construction , but additional hours may be required . This will be during daylight hours , early morning to early evening . If additional hours are anticipated for shift work , a 24 - hour work permit will be obtained from Weld County . The maximum number of construction workers on site at any one time at any work area will be approximately 60 to 80 for the new transmission line when all phases are active . Transmission line construction is expected to be completed in phases over the duration of the construction schedule for each Pathway segment . Construction of the Pathway transmission line is expected to occur in phases that generally include the following : construction access and vegetation clearing , installation of BMPs , equipment mobilization and material delivery , foundation construction , transmission pole placement , and installation , conductor wire stringing and electrical equipment installation , and land restoration . Construction access road improvements , grading , and setup of temporary construction areas ( TCAs ) , along with vegetation work , will be conducted before construction of the transmission line . Proposed access roads will allow construction crews and vehicles to access transmission pole locations and TCAs as needed . Segment 1 construction , including the Pathway facilities in Weld County , is expected to last up to 24 months , with construction beginning in spring / summer 2024 and a target in - service date in spring / summer 2026 . See Section 1 . 1 of this 1041 Application for additional information regarding the Pathway schedule . The transmission line will not have any permanent on - site employees . Upon completion , Pathway will be operated and monitored remotely 24 hours a day , 7 days a week , 365 ( 24 / 7 / 365 ) days a year to provide safe and reliable electric service . The transmission line will be inspected regularly ( at least annually ) to look for the following : • Non - compatible vegetation and hazards within the ROW . • Equipment needing repair or replacement . COLORADO ' S POWER PATHWAY 4 • ROW encroachments , which can be hazardous to safety and reliable operations . • Anything that might jeopardize safe , reliable operation of the power line . Operations and maintenance staff must visit the ROW for these inspections , but visits typically are few , and landowners will be contacted prior to on - site inspections or maintenance . However , in cases of emergency , advanced contact may not be possible . Table 1 shows the estimated maximum number of employees , number of shifts , and employees per shift during the construction and operation and maintenance phases of P athway . Table 1 : Employees and Shifts per Phase Construction Phase Em • to ees Shifts Em • to ees • er Shift Construction 60 to 80 employees for One 12 - hour shift Up to 80 employees transmission line ( Monday to Saturday ) Operations None — the facilities are Remotely monitored None unstaffed with the 24 / 7 / 365 exception of remote monitoring Maintenance 2 - 6 employees 1 to 2 times a month , 2 to 6 employees as needed b . Any future phases or extensions of the facility and relationship of the facility (if currently foreseen) to larger programs and plans . The proposed facilities in Weld County are part of Pathway . Pathway will add a network transmission system that can integrate wind and solar generation sources in the Eastern Plains region of Colorado where they are most efficient to where the energy demand is the highest . By linking the best areas for generating wind and solar energy with where demand is , Pathway will improve the state ' s electric grid and enable future renewable energy development in the Eastern Plains region of Colorado . Pathway will increase electric service safety and reliability , boost the regional economy , and create jobs during construction . This 1041 Application describes a portion of Pathway in Weld County ; the overall system includes approximately 550 to 610 miles of transmission line and new and expanded substations . P athway facilities proposed in Weld County subject to this 1041 Application include 34 . 3 miles of 345 - kV double - circuit transmission line . Other Pathway facilities in Weld County include 11 . 2 miles of 345 - kV double - circuit electric transmission line in existing P SCo fee - owned property and the relocation of 4 . 5 miles of existing 230 - 1( V electric transmission line into new ROW ( subject to a Use by Special Review [ USR ] Permit ) and COLORADO ' S POWER PATHWAY 5 Fort St . Vrain Substation equipment additions ( subject to a Site Plan Review Permit ; see the Vicinity Map in Attachment A ) . c . Timetable for planning (e . g . , federal permits , other state permits , local zoning , etc . ) . A timetable for obtaining required federal , state , and local permits is described in response to Supplemental Question 15 . b . i of this 1041 Questionnaire . d . Estimated beginning and completion of construction and beginning of operation of facility . The estimated schedule for Pathway construction in Weld County is shown in Table 2 . Many variables factor into the schedule for projects of this magnitude . The construction schedule is contingent on acquiring all necessary land rights , permits , labor , and materials . Pathway will be constructed and placed in - service in phases . Table 2 : Anticipated Segment 1 In - Service Dates In - Service Se ! went & Substation Construction Year Segment 1 , including Fort St . Vrain Substation Spring / Summer 2024 — Spring 2026 equipment additions Spring / Summer 2026 3 . Describe hazards and emergency procedures . Specify where applicable : a . Hazards , if any, of fire , explosion and other dangers to the health , safety and welfare of employees and the general public . Transmission lines are built and maintained to meet or exceed safety standards , such as those specified by the National Electrical Safety Code ( NESC ) and the North American Electric Reliability Corporation . Every effort is made to ensure safety in construction , operation , and maintenance of transmission lines . Transmission lines are designed to withstand extreme weather conditions and protective devices at line terminals stop the electricity flow under abnormal operating circumstances . The transmission poles will be equipped with shield wires above the energized line ; this equipment adds to the pole height but also provides protection against lightning strikes . Xcel Energy ' s transmission lines are monitored 24 / 7 / 365 for line contact , the term describing when an object comes in contact with the transmission line conductors . If there is an unanticipated event in the line , the line is isolated from the system to protect the public and the line from operating under unsafe conditions . Xcel Energy ' s transmission lines are inspected annually to check for line connections and damage . COLORADO ' S POWER PATHWAY 6 For the safety of the general public , unauthorized personnel are not permitted to come in contact with the transmission line conductor wire . b . Hazards , if any, of environmental damage and contamination due to materials used at or activities taking place at the proposed facility . Chemicals that may be used during construction and operation are those found in diesel fuel , gasoline , coolant ( ethylene glycol ) , and lubricants in machinery . Hazardous materials will not be drained onto the ground or into streams or drainage areas . Enclosed containment will be provided for trash disposal . Construction waste , including trash and litter , garbage , other solid waste , petroleum products , and other potentially hazardous materials , will be removed and taken to a disposal facility authorized to accept such materials . No hazardous materials will be used , stored , or generated on site of Pathway facilities . Pathway will not require transportation of hazardous materials . Construction , operation , and maintenance activities will comply with applicable federal , state , and local laws and regulations regarding the use of hazardous substances . Construction activities will be performed using methods that prevent entrance or accidental spillage of solid matter , contaminants , debris , and other pollutants and wastes into flowing streams or dry watercourses , lakes , and underground water sources . Activities will follow BMPs for the management of wastes to avoid and minimize effects from potential spills or other releases to the environment . Short - term , temporary increases in fugitive dust and construction equipment exhaust ( fumes ) are anticipated during construction activities . These are not expected to cause a public nuisance . Transmission line operations will not require on - site staff and will be monitored remotely . Visits from personnel will be limited to emergencies or maintenance and inspection activities . As a result , increased dust or exhaust are not expected during operations . Xcel Energy will apply for a Colorado Department of Public Health and Environment ( CDPHE ) Air Pollutant Emissions Notice ( APEN ) for land development prior to construction and follow state standards to control the release of fugitive dust related to construction , if necessary . The APEN will be required for a disturbance greater than 25 contiguous acres and land development activities longer than 6 months . Pathway will not cause hazardous conditions , potential air or water pollutants , or other noxious influences . COLORADO ' S POWER PATHWAY 7 C . Emergency procedures to be used in the event of fire , explosion or other event which may endanger the public health , safety and welfare . Xcel Energy ' s facilities are designed , constructed , operated , and maintained to meet or exceed all applicable requirements of the Institute of Electrical and Electronics Engineers ( IEEE ) standards and accepted industry standards and practices including IEEE 979 , Guide for Substation Fire Protection . Applicable fire laws and regulations , as outlined in Colorado Revised Statutes ( CRS ) 31 - 15 - 601 , will be observed during construction and normal operation of the transmission line and substation . Fires along transmission lines are very rare . Xcel Energy ' s powerlines are monitored and controlled remotely from an operations center where event response is coordinated . In the rare event of an emergency , Xcel Energy will likely be aware of an issue before the general public or emergency responders . Nevertheless , the public is encouraged to contact Xcel Energy ' s emergency number : 800 - 895 - 1999 to report an emergency . Unauthorized personnel , including emergency responders , should not approach the facilities and should not touch the electric lines or anyone or anything in contact with them . Xcel Energy also coordinates closely with local fire departments and first responders and consults with them to discuss any concerns within their response area . Xcel Energy offers free online safety training to fire departments and first responders that is based on national standards through the Responding to Utility Emergencies Program . d . Any prevalent natural hazards that will affect or be affected by development, and describe mitigating measures to be taken to reduce danger due to such natural hazards . Xcel Energy electric facilities , including transmission poles , are specifically designed for the locations where they are placed . Geotechnical studies are conducted for transmission poles to identify subsurface conditions and determine foundation specifications . Transmission lines are structurally designed according to the NESC , which incorporates standards from the American Society of Civil Engineers on structural loading . The NESC requires poles over 60 feet tall to be able to resist the loading from various ice and wind scenarios . The base design wind speed for eastern Colorado is 95 miles per hour . This wind speed is part of an equation that also considers terrain , span length between transmission poles , and transmission pole height to produce an overall wind pressure applied to the wires and the transmission pole . In addition , the design scenario considers how the structural capacity of a transmission pole is affected by the icing conditions on the wire . The weight of the ice increases the tension in the wires and therefore the loading on the COLORADO ' S POWER PATHWAY 8 transmission pole . The result of this design scenario is that transmission lines typically have additional structural capacity for much higher wind speeds than the NESC requires after accounting conservatively for icing conditions . 4 . Summarize major natural and socioeconomic environmental constra ' nts as they affect the site se ection and construction of the facility as proposed . A discussion of environmental constraints is described in the response to Supplemental Question 15 of this 1041 Questionnaire . According to the U . S . Census Bureau ( U . S . Census Bureau 2022 ) , Weld County had a total estimated population of 340 , 036 in 2021 . This is an increase of approximately 3 percent since the 2010 Census . U . S . Census demographics from 2021 for Weld County show a 51 percent male and 49 percent female distribution of the predominantly 91 percent white population . Per capita income in Weld County is $ 35 , 7075 approximately 10 percent lower than the statewide estimate of $ 395545 ( U . S . Census Bureau 2022 ) . In October 2022 , unemployment in Weld County was 3 . 7 percent according to the U . S . Department of Labor : Bureau of Labor Statistics ( FRED 2022a ) . The October 2022 statewide average for unemployment was 3 . 0 percent ( FRED 2022b ) . Pathway will deliver economic benefits to rural communities across eastern and southern Colorado , including Weld County , over the short and long - term . More immediately , Pathway construction will provide local jurisdictions and host communities with potential additional tax revenue and employment opportunities . Revenue may increase for local businesses such as restaurants , gas stations , grocery stores , hotels , and other local businesses . Existing businesses and social services are adequate to support Pathway given the size of the construction crew and temporary nature of the construction activities . No impacts to emergency health care facilities or law enforcement services are therefore anticipated . Once Pathway has been constructed , it will facilitate ongoing job opportunities and tax revenue in the clean energy projects ( wind , solar , etc . ) that ultimately interconnect to Pathway . Additionally , generation developers will have the opportunity to build projects that otherwise were infeasible because of a lack of transmission access to market and / or transmission constraints . These generation projects may provide other additional economic development through increased jobs associated with construction and local tax - based revenue associated with land usage , and payments to existing landowners . COLORADO ' S POWER PATHWAY 9 Xcel Energy anticipates that a maximum number of 60 to 80 construction workers will be needed for construction of Pathway transmission lines in Weld County . Construction crews may reside in the area during construction . 5 . Summarize the effects of the proposed s ' te se ection and construction upon the natural and socioeconomic environment of the impact area as applicable to submission requirements . Included should be an analysis of impacts upon agricultural productivity and agricultural resources and upon vested water rights . An analysis of the effects of the proposed site selection and construction upon the socioeconomic environment of the impact area is provided in the response to S upplemental Question 4 of this 1041 Questionnaire . An analysis of impacts upon agricultural productivity and agricultural resources is provided in the response to S upplemental Question 15 . b . ii and the response to Planning Question 6 of this 1041 Questionnaire . Pathway will not require water rights for construction , maintenance , or operation and will not affect existing water rights . 6 . Inc ude analysis of the long -term effects of the proposed site selection and construction upon the physica and socioeconomic development of the impact area . The development of Pathway in Weld County is anticipated to provide local economic benefits during construction and potential long - term economic benefits should new generation resources be developed in the area . Pathway will also improve the state ' s electric reliability , thereby benefiting all consumers in Colorado . See also the response to Supplemental Question 4 of this 1041 Questionnaire . 7 . Inc ude a description of a program to minimize and m ' tigate adverse impacts and to maximize the positive impacts of the proposed site selection and construction . P athway will mitigate and minimize adverse impacts as described in the responses to S upplemental Question 15 of this 1041 Questionnaire . 8 . Inc ude analysis of nonstructural a ternatives to the project such as conservation of energy use , no development or management ( different schedu ing , conservation programs , facility design , and trades , etc . ) , if applicab e . The purpose of Pathway is to create a network transmission system that can integrate new generation resources needed to meet Colorado ' s clean energy goals . The existing COLORADO ' S POWER PATHWAY 10 infrastructure is not adequate for this purpose . Therefore , no non - structural alternatives are viable . 9 . nc ude analysis of reasonable structura alternatives to the project such as alternate ocations and routes , alternalve types of facilities , use of existing rights - of - way , joint use of rights - of - way with other uti ities , and upgrading of existing facilities . P athway routing and siting efforts were divided by segment and documented in a series of six Routing and Siting studies . Each Routing and Siting Study is interrelated due to the overlap in segment Study Areas and shared substation endpoints . Each Routing and Siting Study documents the process utilized to review and consider reasonable siting and routing alternatives for the new major electrical facilities ( pursuant to CRS 29 - 20 - 108 ( 4 ) ( a ) and ( b ) ) . The Segment 1 : Fort St . Vrain — Canal Crossing Routing and S iting Study is included in Attachment B and provides an alternatives analysis to address this requirement . 10 . Inc ude analysis of air and water pollution impacts and control a ternatives . Air Quality Weld County is in attainment with National Ambient Air Quality Standards ( NAAQS ) for the following criteria pollutants : particulate matter , carbon monoxide , nitrogen oxides , sulfur dioxide , and lead ( EPA 2022 ) . The Denver Metropolitan Area is designated nonattainment for the 8 - hour ozone NAAQS 2015 Standard — Moderate Classification of 0 . 081 up to but not including 0 . 093 parts per million . The Denver Metropolitan Area consists of Adams , Arapahoe , Boulder , Broomfield , Denver , Douglas , Jefferson , and parts of Larimer and Weld counties . S hort - term effects are anticipated from a temporary increase in construction vehicles , which may increase fumes and fugitive dust , construction equipment exhaust ( fumes ) , and clearing and preparing areas for construction ( dust ) . The short - term effects are not expected to cause a public nuisance . If a nuisance arises during construction , the nuisance will be mitigated in coordination with Weld County . It is anticipated that an average of 20 to 30 trucks per day will be utilized during construction of the transmission line for crews , spotting materials , framing poles , and erecting poles . Concrete truck deliveries will be made daily when the foundations and piers are being constructed . Multiple deliveries of cement ( up to 20 to 30 per day ) will be required daily at certain stages of construction . Materials will be delivered to the Cervi Yard at the onset of construction . An additional 10 to 15 trucks will be needed to deliver COLORADO ' S POWER PATHWAY 11 steel poles , conductor , anchor bolts , and foundation materials daily to work areas . The impact to local roads will vary day by day as the construction moves along the route . Water trucks will be utilized during construction activities around roadway access points to suppress dust from vehicles and equipment as necessary within the ROW and county roads as per coordination with Weld County . Xcel Energy will apply for a CDPHE APEN for land development prior to construction and follow state standards to control the release of fugitive dust related to construction , if necessary . The APEN will be required for a disturbance greater than 25 contiguous acres and land development activities longer than 6 months . During operation , Pathway will not generate trips in excess of those currently experienced as the transmission line facilities represent a passive use and will not be staffed . Transmission line operations will not require on - site staff and will be monitored remotely . Visits from personnel will be limited to emergencies or maintenance and inspection activities and increased fumes , exhaust , and dust during operations are not expected . Water Resources An analysis of water resources impacts and control measures is provided in the responses to Supplemental Questions 15 . c . i and 15 . d . i of this 1041 Questionnaire . 11 . Inc ude analysis of design alternatives concerning access , landscaping , archlectural contro s , and so forth . The transmission poles will be weathering steel that oxidizes to resemble a natural brown look . Access to the transmission poles from nearby Interstate , U . S . Highways , and local roads is shown in the 1041 Permit Map , Attachment D . 12 . nc ude analysis of hydrolog ' c , atmospheric , geologic , pedolog ' c , biotic , v . sual and noise impacts . An analysis of atmospheric impacts is provided in the response to Supplemental Question 10 of this 1041 Questionnaire . An analysis of hydrologic , geologic , pedologic , biotic , visual , and noise impacts is provided in the responses to Supplemental Question 15 of this 1041 Questionnaire . 13 . Include surface and subsurface drainage analysis . Xcel Energy will comply with permit application requirements , County Standards , and construction protocols to ensure that Pathway does not violate water quality standards . COLORADO ' S POWER PATHWAY 12 A Drainage Narrative is provided in the response to Engineering Question 3 of this 1041 Questionnaire . 14e App ' cants seek ' ng a permit for the site selection and construction of transmission Ines or substations shall submit the fol owing additional documents and information : a . Computer modeled electromagnetic field measurements within the proposed transmission line easement for that portion of transmission line between substations or transition sites ; and Pathway facilities will be designed , constructed , operated , and maintained to meet or exceed applicable standards of design and performance set forth in the NESC . Electric and magnetic fields ( EMF ) exist wherever electricity is produced or used , including around any electric appliance or wire that conducts electricity . Electric fields are created by voltage — the higher the voltage , the stronger the field . Any time an electric appliance is plugged in , even if it is not on , an electric field is created in its vicinity . Electric fields are easily blocked by walls , trees , clothes , and skin . The farther the distance from the source of the electric field , the weaker it becomes . EMF extend outward from the conductor wire and decrease rapidly with distance from the conductor . There is no federal standard for transmission line EMF . Additional information is available online at Transmission - EMF - Fact - Sheet . pdf ( coloradospowerpathway . com ) . Noise and EMF studies were conducted for Pathway and submitted as part of Pathway ' s Certificate of Public Convenience and Necessity ( CPCN ) application , and is included as Attachment O . The study concluded that magnetic field levels at the edge of the Pathway transmission line ROW are projected to be 54 . 7 milligauss ( mG ) . These levels are below 150 mG and were deemed reasonable by the Colorado Public Utilities Commission ( CPUC ) . b . Measures taken to comply with the concept of prudent avoidance with respect to planning , siting , construction and operation of transmission lines , which may be those steps taken to comply with the Colorado Public Utilities Commission 's Rule 18 ( 1) , or similar authority, for projects where other similar authority is applicable . The routing and siting study process used to locate Pathway facilities in Weld County is provided in Attachment B of this 1041 Application . In February 2022 , the CPUC provided verbal approval for the CPCN for Pathway Segments 1 through 5 and conditional approval for the Extension , determining Pathway is in the public interest and COLORADO ' S POWER PATHWAY 13 in compliance with relevant CPUC rules and regulations . The CPUC provided written approval of the Pathway CPCN application on June 2 , 2022 . 15 . Specrc submitta requirements . he fo lowing informat ' on may also be required : a . Detailed description of the need for the proposed development or activity, including► but not limited to : i The present population of the area to be served and the total population to be served when the project is operating at full capacity, The purpose of Pathway is to create a network transmission system that can integrate new generation resources needed to meet Colorado ' s clean energy goals . Pathway is a backbone transmission system that will connect generation sources in eastern Colorado to demand throughout Colorado . The current electric transmission facilities in the Eastern Plains do not have adequate capacity to meet the forecasted demand . Facilities in Weld County are part of the larger Pathway that creates a transmission " loop " to provide additional transmission capacity . Pathway will be able to integrate approximately 3 , 000 to 3 , 500 megawatts of electric power output from new generation . ii The predominant type of users or communities to be served by the proposal . P athway is an addition to Colorado ' s backbone transmission system and does not provide distribution electric service ; as such , this Application does not address project - specific details that apply for developments or direct utility service projects . iii The percentage of the design capacity at which the current system is now operating .

P athway will support Xcel Energy ' s Clean Energy Plan ( Xcel Energy 2021 ) that is estimated to deliver as much as an 85 percent reduction in carbon dioxide emissions by 2030 and add approximately 5 , 000 megawatts of new wind , solar , and other resources . P athway is a $ 1 . 7 to $ 2 billion investment proposed by Xcel Energy to improve the state ' s electric grid and enable future renewable energy development around the state . COLORADO ' S POWER PATHWAY 14 v A description of why public convenience and necessity require a facility of the size and nature proposed . The Eastern Plains region of Colorado is one of the nation ' s best areas for wind and solar energy generation , but it does not currently have a network transmission system that can integrate these new generation resources into the state ' s interconnected grid system , which is needed to meet Colorado ' s clean energy goals . Pathway will help to meet the state ' s growing electricity needs , improve safety , reliability , and affordability , and enable the transition to clean energy . Pathway will allow developers of energy generation projects to interconnect energy resources located in the areas of the state that are underserved by backbone transmission lines and allow Xcel Energy to deliver energy to electric customers . In March 2021 , Xcel Energy filed a CPCN to the CPUC describing the purpose , need , and public benefits of constructing Pathway . In February 2022 , the CPUC provided verbal approval , and in June 2022 , CPUC provided written approval of the CPCN for S egments 1 to 5 and conditional approval for the Extension , based on a determination that Pathway is in the public interest . vi A description of the user needs and user patterns to be fulfilled by the proposed project . S ee the response to Supplemental Question 15 . a . v of this 1041 Questionnaire . vii A description of the relationship of the project to other existing and planned utility facilities of a similar nature , other communication or energy generation and transmission facilities , local government capital improvement programs and special district expansion programs .

Federal , state , and local permits and approvals may be required prior to Pathway construction . Outreach was conducted with each jurisdiction crossed by Pathway to solicit feedback and discuss potential permits that may be required . Multiple Colorado statutory provisions and local government land use plans and controls apply to Pathway , including approval of a CPCN from the CPUC ; notice , consultation , and permit approvals from counties and municipalities , and notice to owners of a mineral estate associated with the substation sites . All necessary land use , environmental , and construction permits , approvals and authorizations will be obtained prior to the start of and during construction as required and may include but are not limited to major land use permits , ROW permits , road use agreements , access permits , oversize / overweight permits , grading permits , and stormwater permits . Xcel Energy anticipates avoiding impacts to jurisdictional waters of the U . S . ( WOTUS ) in Weld County and therefore does not anticipate that Pathway facilities in the County will require a Nationwide Permit 57 or other U . S . Army Corps of Engineers permitting under Section 404 of the Federal Clean Water Act . The regulatory requirements identified by Xcel Energy are described in Table 3 . Table 3 is intended as an illustrative list of the permits and approvals that may be required for Pathway , but other permits or approvals may be required .

The Jurisdiction Resource Maps in the Routing and Siting Study for Segment 1 ( Attachment B ) illustrate land jurisdiction for Pathway in Weld County . No federally or state - managed conservation areas are within 1 mile of proposed Pathway facilities in Weld County . In addition , no Critical Habitat designated by the U . S . Fish and Wildlife Service ( USFWS ) is mapped in the same area ( USFWS 2022d ) . Beyond these priority habitats , Pathway will avoid or minimize impacts to habitat generally as practicable . Impacts to most vegetation will be temporary and limited to the 150 - foot - wide ROW and TCAs . The ROW will be cleared of tall vegetation for ongoing maintenance . Measures will be implemented to minimize the spread of noxious weeds in the ROW as provided in Attachment X . To avoid or minimize impacts to aquatic habitat within the ROW , surface waters , riparian areas , and wetlands in areas at a crossing will be spanned as practicable . Pathway will adhere to BMPs and erosion control measures outlined in the SWMP . Special Status Wildlife A desktop analysis of the portion of Pathway transmission lines within Weld County was completed to characterize the environmental setting of Pathway and evaluate the potential for occurrence of special - status species based on available habitat . The COLORADO ' S POWER PATHWAY 25 analysis included the transmission line route plus a 1 - mile buffer . The buffer was used to evaluate biological resources that could be influenced by Pathway construction , maintenance , or operation ( e . g . , raptor nests ) . To assess the potential for occurrence of special - status species within the County , the following publicly available information was reviewed : • Google Earth Aerial Imagery ( Google 2022 ) • National Land Cover Database ( USGS 2019 ) • USFWS Information for Planning and Consultation ( IpaC ) online tool ( USFWS 2022a ) • USFWS Critical Habitat Portal ( USFWS 2022b ) • Colorado Natural Heritage Program Species Elements Database ( CNHP 2022 ) • Colorado Parks and Wildlife ( CPW ) Species Activity Mapping Data ( CPW 2022a ) • CPW State Species List ( CPW 2022b ) • Online species profiles and distribution information ( CPW 2022c ) In addition to publicly available information , a windshield survey of the proposed Pathway facility locations was completed in September 2021 to identify any potential areas of concern for biological resources . Ground - based raptor nest surveys and aerial raptor nest surveys were conducted in April and May 2022 to identify potentially active eagle and other raptor nests within 0 . 5 mile of the proposed transmission line route in Weld County . The Pathway team has been conducting ongoing coordination with CPW and USFWS regarding potential biological resources that may be impacted by Pathway . The Pathway team had a project introduction meeting with CPW on December 12 , 2021 , followed by a routing workshop on January 10 , 2022 , and afollow - up routing discussion on April 22 , 2022 . On May 9 , 2022 , the Pathway team had a project introduction meeting with USFWS . The feedback received from CPW and USFWS during these meetings has been used to inform the siting and routing of Pathway . The Pathway team will continue to coordinate with CPW and USFWS through permitting , construction , maintenance , and operation of Pathway as needed to ensure compliance with applicable federal and state regulations . COLORADO ' S POWER PATHWAY 26 d . Environmental impact analysis — significant environmentally sensitive factors . Detail the potential impact of the proposal upon each feature : A map of Significant Environmentally Sensitive Factors is provided as Attachment M . f Marshlands and wetlands . A desktop analysis of the portion of Pathway within Weld County was completed to identify potentially jurisdictional wetlands and other WOTUS that may be subject to regulation under Section 404 of the Clean Water Act . The following digital information was evaluated for the 150 - foot ROW and an additional 50 - foot buffer on either side of the ROW : • USFWS National Wetland Inventory ( NWI ) dataset ( USFWS 2022c ) • USGS National Hydrography Dataset ( NHD ; USGS 2022a ) • Playa Lakes Joint Venture Probable Playa Dataset ( PLJV 2022 ) The Water Resources Map in the Routing and Siting Study for Segment 1 ( Attachment B ) illustrates the mapped NWI , NHD , and PLJV locations within the Study Area for Weld County . The major NHD - mapped drainages associated with wetlands and other WOTUS features near proposed Pathway facilities in Weld County include the South Platte River , Box Elder Creek , and associated unnamed tributaries ( USGS 2022a ) . NWI - mapped features associated with these drainages include riverine wetlands and freshwater emergent wetlands ( USFWS 2022c ) . As outlined in Table 6 , the transmission line ROW intersects 23 of these mapped wetland features , of which the longest crossing of which is approximately 557 feet . The nearest PLJV - mapped playa is located approximately 0 . 4 mile south of the Pathway facilities and no impacts are anticipated ( PLJV 2022 ) . The Cervi Yard does not intersect mapped NWI , NHD , or PLJV locations .

The potential wetlands and WOTUS identified through desktop analysis of NWI data that may be impacted by construction of Pathway have been field - verified and will be marked in the field prior to construction so construction workers avoid impacts . The transmission poles can be located to span wetlands and other WOTUS features , thereby avoiding permanent impacts . Based on the lengths provided in Table 6 , P athway pole siting is not anticipated to result in permanent impacts to wetlands or other WOTUS features in Weld County . Associated access roads , laydown yards , and other features of Pathway will be sited to avoid permanent impacts to wetlands and WOTUS features . Pathway is therefore not anticipated to result in permanent impacts to wetlands or other WOTUS features in Weld County . Temporary impacts to wetlands and WOTUS during construction of Pathway will be avoided to the extent practicable . If wetlands cannot be avoided , matting and other protective temporary measures will be used . Depending on the condition of the wetland soil and hydrology , matting may be used to protect wetlands from rutting . Prior to construction , a Storm Water Management Plan ( SWMP ) will be prepared according to the Colorado Department of Public Health and Environment ( CDPHE ) requirements . To avoid potential indirect impacts from construction - related erosion and sediment movement during construction , Pathway will adhere to BMPs outlined in the SWMP , which will include erosion control and revegetation measures . P athway will not generate pollutant loads . Construction of the transmission line will not create runoff in excess of preconstruction levels and will not change existing topography or adversely affect drainage . There will be no alteration in the pattern or intensity of surface drainage as a result of construction or operation of the transmission line . COLORADO ' S POWER PATHWAY 28 Xcel Energy will comply with permit Application requirements , County Standards , and construction protocols to ensure that Pathway does not violate water quality standards . ii Groundwater recharge areas , if applicable . No groundwater discharge areas are located near Pathway ( see Attachment M , S ignificant Environmentally Sensitive Factors Map ) . No impacts to groundwater recharge areas are anticipated . BMPs will be used during construction to control sediment and runoff from work areas . Compliance with applicable federal , state and county construction and waste management procedures will prevent accidental spills or runoff of sediment or contaminants to waterbodies or groundwater . iii Potential natural hazards . No areas of geologic hazards or geologic areas of importance are located near P athway . No significant natural hazards have been identified in the areas planned for P athway development in Weld County . Professional engineers who will guide construction do not foresee any unusual risks . Xcel Energy electric facilities , including transmission poles , are specifically designed for the locations where they are placed . Geotechnical studies are conducted for transmission poles to identify subsurface conditions and determine foundation specifications . Transmission lines are structurally designed according to the NESC , which incorporates standards from the American S ociety of Civil Engineers on structural loading . The NESC requires poles over 60 feet tall to be able to resist the loading from various ice and wind scenarios . The base design wind speed for eastern Colorado is 95 miles per hour . This wind speed is part of an equation that also considers terrain , span length between transmission poles , and transmission pole height to produce an overall wind pressure applied to the wires and the transmission pole . In addition , the design scenario considers how the structural capacity of a transmission pole is affected by the icing conditions on the wire . The weight of the ice increases the tension in the wires and therefore the loading on the transmission pole . The result of this design scenario is that transmission lines typically have additional structural capacity for much higher wind speeds than the NESC requires after accounting conservatively for icing conditions . iv Forests and woodlands . The Land Cover Resource Maps in the Routing and Siting Study for Segment 1 ( Attachment B ) illustrate land cover for Pathway in Weld County . Forested areas in the vicinity of the transmission line route are shown in the Significant Environmentally S ensitive Factors Map ( Attachment M ) . As shown in Tables 4 and 5 ( see response to Question 15 . c . ii ) , the total area of forested and woodland land cover within 1 mile of proposed Pathway facilities is less than 0 . 1 percent ; there are no forested or woodland COLORADO ' S POWER PATHWAY 29 areas within or adjacent to the Cervi Yard . Pathway transmission lines will avoid or minimize impacts to forests and woodlands generally as practicable . Impacts to most vegetation will be temporary and limited to the 150 - foot - wide ROW and TCAs . The ROW will be cleared of tall vegetation for ongoing maintenance . Measures will be implemented to minimize the spread of noxious weeds in the ROW as described in Attachment X , including minimizing ground disturbance and utilizing weed - free seed mixes . v Critical wildlife habitat . The USFWS iPaC online tool and CPW online databases were used to identify federally and state - protected species that may occur near Pathway facilities in Weld County , including species listed or proposed for listing under the Endangered Species Act , bald and golden eagles protected under the Bald and Golden Eagle Protection Act , and state - listed threatened or endangered species ( CPW 2022a , CPW 2022b , CNHP 2022 , U SFWS 2022a , USFWS 2022b ) . In addition to the federally and state - listed species that receive regulatory protection , state Species of Concern ( SC ) were also evaluated . Although SC species do not receive any regulatory protection , they have been identified by the state as having management interest either due to declining populations or habitat loss . The Wildlife Species Habitat and Avian Habitat Resource Maps in the Routing and S iting Study for Segment 1 ( Attachment B ) illustrate mapped special - status wildlife and avian habitat for Pathway in Weld County . A total of 19 special - status wildlife species were identified as potentially occurring within 1 mile of proposed Pathway facilities in Weld County . Table 7 outlines the likelihood of occurrence of each species based upon review of known species ranges , habitat requirements , land cover data , and aerial imagery .

Of these 19 species , three federally protected or candidate species ( golden eagle , bald eagle , and monarch butterfly ) and one state - protected species ( burrowing owl ) were determined to have a moderate or high likelihood of occurrence within the 1 - mile buffer of proposed Pathway facilities in Weld County . In addition to listed species , CPW tracks and maps data for big game species habitat throughout the state ( CPW 2022a ) . The Wildlife Species Habitat Resource Maps in the Routing and Siting Study for Segment 1 ( Attachment B ) illustrate mapped big game habitat for Pathway in Weld County . Three mule deer ( Odocoileus hemionus ) winter concentration areas , three areas identified as winter range , two areas identified as winter concentration area and two areas identified as severe winter range occur within the 1 - mile buffer of proposed Pathway facilities . The following occur within the 1 - mile buffer of proposed the Pathway facilities in Weld County : • one pronghorn antelope ( Antilocapra americana ) concentration area , one area identified as winter range , one area identified as winter concentration , and one area identified as severe winter range • one white - tailed deer ( Odocoileus virginianus ) concentration area and two areas identified as winter range No other big game species habitat is mapped in the same area . COLORADO ' S POWER PATHWAY 33 Potential impacts to wildlife species would primarily be associated with temporary disturbance from construction activities within the ROW , namely the removal and management of vegetation . In addition , increased noise and equipment movement during construction may temporarily displace mobile wildlife species from the immediate workspace area . These impacts are considered short - term in duration and normal wildlife movements would be expected to resume after construction has been completed and disturbed areas have been restored in a manner generally similar to preconstruction conditions . To avoid or minimize impacts to wildlife , Pathway will implement measures such as requiring proper trash and food debris disposal and compliance with posted speed limits . CPW recommendations ( CPW 2021 ) will be incorporated where practicable . To avoid or minimize potential project impacts to eagles and other migratory birds and raptors , tree / vegetation clearing will be conducted during the nonbreeding season for birds ( September 1 — April 15 ) if feasible . If vegetation clearing cannot occur during the nonbreeding season , vegetation clearance surveys , raptor nest surveys , and burrowing owl surveys may be conducted per USFWS and CPW guidance to identify avian nesting activity and determine appropriate avoidance buffers ( CPW 2020 , CPW 2021 ) or monitor actives nest sites until determined to be inactive . In addition , electrical components of the transmission lines will be separated to minimize the risk of avian contact and will follow Avian Power Line Interaction Committee ( APLIC ) guidelines ( APLIC 2006 ) . Bird flight or swan diverters or other marking devices may be used as determined necessary for specific locations . Xcel Energy will continue to coordinate with USFWS and CPW to address concerns regarding wildlife impacts throughout planning , design , and construction of Pathway , and will comply with all regulatory requirements . vi Public outdoor recreation areas . No local public outdoor recreation areas are present in the vicinity of Pathway facilities in Weld County ( USGS 20224 No impacts to recreation areas are anticipated . vii Unique areas of geologic , historic or archeological importance . Pathway facilities will be located in areas mapped as alluvium , eolian deposits , residuum weathered from shale , and mixed deposit outwash ( NRCS 2019 ; see Attachment V , Soil Report ) . A geotechnical study , based on soil borings along the length of the transmission line will be conducted for Pathway . Engineers will use this study to determine the size and type of foundations needed to support transmission poles as well as soil resistivity . No significant natural hazards have been identified in the COLORADO ' S POWER PATHWAY 34 areas planned for Pathway development in Weld County . Professional engineers will guide construction and do not foresee any unusual risks . Both a desktop cultural resources study and a field reconnaissance survey ( from May 5 to 6 , 2022 ) were completed where proposed Pathway facility locations and potential historic or archeological resources in Weld County were visible from public roads . Cultural resource records were reviewed using archaeological site files and the Colorado Cultural Resource Online Database ( Compass ) maintained by the Colorado Historic Society Office of Archaeology & Historic Preservation . Included in the Compass database are records of properties listed in the National Register of Historic Places . The cultural resources site file search was conducted for the 150 - foot transmission line ROW . Within the 150 - foot buffer , 22 previous cultural resource surveys have been conducted . These surveys cover over 8 miles of Pathway ROW . Six previously recorded cultural resources are located within the ROW . The resources include four historic ditch segments , one railroad segment , one transmission line , one Centennial Farm , and two isolated lithics . Three sites within the 150 - foot transmission line ROW have been determined Eligible for listing in the National Register of Historic Places . These sites include a segment of the Union Pacific Railroad ( 5WL . 1969 . 34 ) , a segment of the Farmers Independent Ditch ( 5WL . 2589 . 2 ) , and the Kiowa Creek to Weld Transmission Line ( 5WL . 3155 ) . Pathway will span these resources . One site , 5WL . 2083 , is a Centennial Farm and is Unevaluated . The boundaries of Centennial Farms encompass all areas of the farm , including areas that have no cultural features . The transmission line will avoid any areas with cultural features . The remaining sites include two that have been determined Not Eligible and two sites that are recommended Not Eligible . The sites that are recommended Not Eligible are isolated finds that can only be eligible under very rare circumstances , and neither of these resources fulfill these requirements . Therefore , Pathway will not have an adverse effect on any cultural resource . COLORADO ' S POWER PATHWAY 35 e . Environmental impact analysis - visual aesthetics and nuisance factors . i Identify key locations where the facility can be viewed from and its proximity to residences , simulate the appearance of the facility_, and identify noise pollution or obnoxious odors which may stem from the proposal . Visual / Aesthetic Resources Visual simulations from selected representative locations where Pathway can be viewed are provided in Attachment N . High - use roads and highways and residential land uses were prioritized in selecting the locations of the key viewpoints . A visual resource inventory based on available data found no designated federal , state , or local scenic resources within 2 miles of the Pathway transmission line route in Weld County . Several parcels adjacent to the eastern portion of the Pathway transmission line route in Weld County are owned and managed by Colorado State Land Board ; however , these areas are not accessible to the public or improved for any recreational , scenic , or other use . The Pathway transmission line route through Weld County , selected key observation points ( KOPs ) and identified public lands in the vicinity are shown in Attachment N on the KOP Resource Inventory map . The existing visual landscape in the area around the proposed Pathway transmission line route consists of mainly agricultural land uses including pivot irrigated crops and pastureland . Trees are sparse and shrub / scrub and herbaceous land cover dominate the area . Industrial facilities present near Pathway include oil and gas wells , natural gas compressor station facilities , communication facilities , oil and gas pipelines , a photovoltaic solar facility , a landfill , and a tire recycling facility . Agricultural facilities located near Pathway include cultivated crops , cattle feed yards , a confined animal feeding operation , and a meat processing facility . Electric distribution lines are visible throughout the area and are generally located along roads to serve residential and commercial areas . Several existing high voltage transmission lines and electrical substations are located in Weld County ( HIFLD 2022 ) . Other linear infrastructure , including railroads , Interstate Highways , U . S . Highways , and local roads exist in proximity to Pathway . Three residences are located within 300 feet of the Pathway transmission line centerline through Weld County . Visual impacts of Pathway will vary based on proximity . With increased distance , the scale of the transmission line poles will be minimized . As demonstrated by the visual simulations ( Attachment N ) , Pathway will be visible and , in some cases , dominant from roadways and a small number of residences , particularly where it occurs near viewers , up to approximately 0 . 5 mile . Viewers would primarily include motorists / travelers on COLORADO ' S POWER PATHWAY 36 roads ( who would view Pathway dynamically and briefly as they pass in a vehicle at highway speeds ) and residents located in the vicinity of Pathway whose views would be static and of longer duration . Roadways that intersect with or would have foreground views of Pathway include several Weld County Roads and Interstate 76 . Table 8 lists the views selected for photo simulations and a description of the simulation results . Where Pathway would be visible in the immediate foreground , it would introduce tall , vertical elements that are in some cases larger in scale than existing distribution lines located in the area and would appear as a dominant feature . Viewers located farther away are likely to experience less visual impact because screening from existing features ( topography , vegetation , buildings ) and distance from the facilities will decrease potential views and visual dominance .

An existing distribution line is present in the view , parallel with Weld County Road 59 . 1 - A total of 10 locations in proximity to the Pathway transmission line route through Weld County were visited in the field in January 2023 to document existing conditions and collect field photos for the simulations . Of those 10 locations , 4 representative locations were selected for simulations . COLORADO ' S POWER PATHWAY 37 Noise and Nuisance Factors The CPUC provides reasonableness determinations associated with noise and requires CPCN applicants to evaluate the expected level of noise of the proposed transmission facilities . Xcel Energy is required to meet state standards as outlined in 4 CCR 723 - 3 . Construction - related noise will result in temporary short - term increases in noise in areas where construction and staging are taking place . Short - term noise will result during foundation construction and assembly and erection of the transmission line poles and is anticipated from construction equipment such as auguring machines , cranes , heavy machinery , and trucks . Indirect effects from post - construction activities , which include the noise from transmission line inspections and maintenance activities are anticipated to be negligible because of their short duration and infrequency . All high - voltage transmission lines experience significant corona during wet weather , when water droplets form on the line . In normal , fair - weather conditions , corona and its corresponding audible noise are usually at low levels ( approximately 25 decibels less than wet weather noise ) . Corona also increases approximately 1 decibel for every 1 , 000 feet in elevation gain . Based on the noise study conducted for Pathway ( Attachment O ) , the maximum projected noise level measured at 25 feet from the edge of the ROW is 49 . 8 A - weighted decibels ( dBA ) . Per CPUC Rule 3206 ( f ) , noise levels below 50 dBA are not subject to further review regardless of the use of land , and noise levels below 75 dBA are deemed reasonable for land within an Industrial Zoning at 25 feet from the property line ( Section 4 CCR 723 - 3 ) . The projected noise levels from the Pathway transmission line were deemed reasonable by the CPUC and not subject to further review . it Where significant, reap or describe areas Within view of project . Visual simulations from key locations where Pathway can be viewed are provided in Attachment N . Describe proposed mitigation strategy . Where feasible , the Pathway route through Weld County is collocated along existing infrastructure to minimize impacts to the surrounding area . The type of steel used will be weathering steel that oxidizes to resemble a natural brown look and is not shiny . The visual landscape along the route features existing transmission lines , roadways , and industrial elements , and Pathway will result in an incremental increase in infrastructure in the viewshed . COLORADO ' S POWER PATHWAY 38 Existing undisturbed trees , shrubs , and native vegetation will be preserved to the extent possible to maintain visual contrast in the landscape . Following construction , the ROW will be restored in a manner generally similar to pre - construction conditions consistent with previous representations . Construction vehicles and equipment will be maintained in proper operating condition and equipped with manufacturer ' s standard noise control devices ( e . g . , mufflers or engine enclosures ) . f Environmental impact analysis — Transportation impacts . i Describe what impacts the proposal will have upon transportation patterns in the area intended to be served or affected by the proposal . Construction of Pathway is not expected to cause significant effects to Weld County transportation , and any impacts will be temporary in nature . Work crews will mobilize each day from the laydown yard to the work areas . Traffic to local work areas will be limited to supervisory vehicles transporting work crews , required construction equipment , and equipment delivery vehicles . Construction equipment or labor transportation are not anticipated to have a significant impact on traffic volumes or flow on local roadways or state / county highways . Any increases in traffic will be short term and limited to the construction time period near individual transmission poles . P athway will cross the existing Burlington Northern Santa Fe Railroad in Weld County near Weld County Road 95 % and Weld County Road 26 % approximately 5 miles southwest of Wiggins . Xcel Energy will obtain all appropriate permits from the Burlington Northern Santa Fe Railroad . No impacts to the existing railroad are anticipated . P athway will cross I - 76 / US - 6 approximately 2 . 5 miles east of the Weld County Road 73 interchange at Roggen . Xcel Energy will obtain required permits from CDOT . No impacts to transportation on I - 76 / US - 6 are anticipated . P athway is not located within the approach or departure zone of any airports in Weld County . The closest airport to the Pathway route within Weld County is approximately 1 . 75 miles away . Therefore , no impacts to airports are anticipated . Xcel Energy will file with FAA as necessary for certain poles or areas of the line . ii Describe the potential impact on roads within the County . The portion of the Pathway transmission line subject to this 1041 Application will cross I - 76 , US - 6 , the 1 - 76 Frontage Road , and the following Weld County Roads : 28 , 31 , 33 , 386 ( Phanter Road ) , 39 , 41 , 43 ( Cavanaugh Road ) , 49 , and 59 . Traffic will be delayed temporarily for the time it takes to string conductor across the road . Traffic Control Plans will be developed in areas where travel on roadways could be impacted during COLORADO ' S POWER PATHWAY 39 construction . Construction updates and schedules will be discussed with local government officials as needed as details are determined . Necessary road use and ROW permits will be obtained from Weld County as needed prior to construction . Identify improvements required to any roads within the County in order to serve the project adequately . Where practicable , existing public roads and private roads will be utilized during Pathway construction , maintenance , and operation . Some private roads may require improvements and some new access roads will need to be constructed to accommodate construction equipment and long - term maintenance of the transmission line . Where road improvements are needed , Xcel Energy will acquire any necessary grading , stormwater , and erosion control permits and comply with permit requirements . Xcel Energy will acquire access easements where necessary access routes traverse private property . Some access routes may remain post - construction to maintain access to transmission lines for operation and maintenance activities . g . Environmental impact analysis — less damaging alternatives . f the Planning Department determines that the nature or extent of the proposal involves the potential for significant environmental damage or warrants examination of specific , less environmentally damaging alternatives , the Planning Department may request that the Board require the applicant evaluate and present information on such alternatives as part of the application . Required information on alternatives may include , but shall not necessarily be limited to , information on the environmental impacts and cost- effectiveness of the alternatives in relationship to the proposal presented . The process utilized to review and consider reasonable siting and routing alternatives is described in the Segment 1 : Fort St . Vrain — Canal Crossing Routing and Siting Study ( Attachment B ) and the response to Supplemental Question 9 of this 1041 Questionnaire . COLORADO ' S POWER PATHWAY 40 PLANNING QUESTIONS 1 . Exp a ' n , in detai the proposed use of the property . Include , at a minimum , the fo lowing : a . Current or previous use of the land, if any . Of the 45 miles of proposed Pathway 345 - kV double - circuit transmission line transmission line routing planned for construction in unincorporated Weld County , 34 . 3 miles of the route will be located in newly acquired transmission line easements and ROWs that will require permitting subject to this 1041 Application . Approximately 3 miles of the Pathway route subject to this 1041 Application will be located adjacent to an existing electric transmission corridor west of I - 76 , 6 . 5 miles will be adjacent to or near 1 - 76 , and 2 miles of the transmission line will be adjacent to an existing railroad . The transmission line will be located across A ( Agricultural ) Zone District lands within Weld County . The transmission line will traverse lands currently u sed for agriculture ( crop and animal production ) , oil and gas development , and grassland / grazing areas ( see Attachment P , Agricultural Lands Map ) . To mitigate against any negative impacts this transmission line route might have on the active farmlands surrounding it , Xcel Energy has worked directly with the individual surface u se owners to strategically locate the alignment proposed along the quarter section lines and along property lines to avoid as feasible impacts on farming and other types of agricultural operations in the area . b . Describe the uses surrounding the site and explain how the proposed use is compatible with them . Existing land uses present near Pathway facilities include industrial facilities , oil and gas wells , natural gas compressor station facilities , communication facilities , oil and gas pipelines , a photovoltaic solar facility , a landfill , a tire recycling facility , and several existing high voltage transmission lines and electric distribution lines . Agricultural facilities located near Pathway facilities include cultivated crops , cattle feed yards , a confined animal feeding operation , and a meat processing facility . Other linear infrastructure , including railroads , Interstate Highways , U . S . Highways , and local roads exist in proximity to Pathway . Pathway is compatible with these uses because it has been sited specifically to minimize surface - use impacts to the surrounding community and preserve land for agriculture , rangelands , wetlands , and critical habitat areas . Because Pathway will be u nstaffed and monitored remotely 24 / 7 / 365 , with only annual site visits to inspect the overall infrastructure , no impacts will be felt from long - term additions of traffic or COLORADO ' S POWER PATHWAY 41 services needed on the region . Once Pathway has been completed , it may result in job opportunities and employment in the energy projects that ultimately interconnect to P athway and align with the intent of the zone district as further energy development will be possible with Pathway ' s development . c . Describe the proximity of the proposed use to residential structures . Avoidance of residential subdivisions and planned development were major factors in identifying the preferred and alternative routes ( see Attachment B , Routing and Siting S tudy for Segment 1 ) . Residential areas are concentrated near the municipalities of Gilcrest , Platteville , Fort Lupton , Hudson , Keenesburg , Roggen , Wiggins , Fort Morgan , and Log Lane Village . Residences are few and widespread within the more rural parts of unincorporated Weld County where Pathway is sited . Existing residences are shown on Attachment A , Vicinity Map . d . Describe the hours and days of operation (e . g . Monday thru Friday 8 : 00 a . m . to 5 : 00 p . m . ) . The utility line , once in operation , will be in operation 24 / 7 / 365 . See the response to S upplemental Question 2 of this 1041 Questionnaire . e . List the types , number, and uses of the proposed structures to be erected . A description of the Pathway transmission line and other related facilities subject to this 1041 Application is provided in Section 1 . 4 of this 1041 Application . f. Describe the size of stockpile , storage or waste areas to be utilized, if any . Once Pathway is operational , no permanent stockpile or storage areas will be required . TCAs will be used during construction to stage construction equipment and materials including construction trailers , portable toilets , cranes , and transmission poles . At the end of each construction phase , equipment will be removed from the TCAs for that construction phase . No proposed improvements at the TCAs will be permanent , and TCAs will be restored in a manner generally similar to pre - construction conditions . See S ection 1 . 4 . c of this Application for additional information regarding TCAs , including the Cervi Yard . All required Grading and Access Permits will be obtained prior to construction of P athway in Weld County . COLORADO ' S POWER PATHWAY 42 g . Describe the method and time schedule of removal or disposal of debris , junk and other wastes associated with the proposed use . P athway is not anticipated to generate pollution during operations and maintenance and will not require permanent pollution control equipment once in operation . Required federal , state and county construction and waste management procedures will be followed to prevent accidental spills or runoff of sediment or contaminants to waterbodies or groundwater . Once construction has been completed , construction equipment and materials will be removed from the site and waste products from the construction process will be properly disposed of as needed . Areas that will not be needed for operations and maintenance will be reclaimed in a manner generally similar to their condition before construction or as may be provided for in private agreements ( including re - seeding per Xcel Energy ' s vegetation management standards and S WMP ) . h . Include a time table showing the periods of time required for the construction of the operation . S ee the response to Supplemental Question 2 of this 1041 Questionnaire . i . Describe the type of lot surface proposed and the square footage of each type (e . g . asphalt, gravel, landscaping , dirt, grass , buildings) . The proposed Pathway facilities subject to this Application are 34 . 3 miles long by 150 feet wide and is located across A ( Agricultural ) Zone District active farmland and rangeland . The transmission line alignment spans existing irrigation ditches and pivot irrigation in fields and follows section lines , road ROWs , and property boundaries to minimize impact to existing uses and agricultural operations ( see Attachment P , Agricultural Lands Map ) . Permanent Pathway facilities will be limited to the footprint of the individual transmission poles and transmission access roads ( see Section 1 . 4 . c of the Application ) . With the exception of these areas , remaining areas disturbed during construction will be reclaimed in a manner generally similar to their condition prior to construction or as may be provided for in private agreements ( including by re - seeding in accordance with Xcel Energy ' s vegetation management standards and SWMP ) . j . How many parking spaces are proposed ? How many handicapped (ADA ) parking spaces are proposed ? No permanent public parking spaces are proposed or required for Pathway because the transmission line will be unstaffed and monitored remotely 24 / 7 / 365 once in operation . During construction , access drives from nearby roads for construction and maintenance will be incorporated into the transmission line design and temporary parking of COLORADO ' S POWER PATHWAY 43 construction vehicles will be located within the designated TCAs . Once construction has been completed , areas not needed for operations and maintenance will be reclaimed in a manner generally similar to their condition prior to construction or as may be provided for in private agreements ( including by re - seeding in accordance with Xcel Energy ' s vegetation management standards and SWMP ) . k . Describe the proposed screening for all parking and outdoor storage areas . No fencing or screening is proposed because no permanent parking or outdoor storage areas are proposed . I . Describe the existing and proposed landscaping for the site . Given the small area occupied by the transmission poles , and the minimal anticipated visual impact , landscaping is not proposed as part of Pathway . Existing undisturbed trees , shrubs , and native vegetation will be preserved to the extent practicable to maintain visual contrast in the landscape . Once construction has been completed , areas not needed for operations and maintenance will be reclaimed in a manner generally similar to their condition prior to construction or as may be provided for in private agreements ( including re - seeding in accordance with Xcel Energy ' s vegetation management standards and SWMP ) . m . Describe the type of fence or other screening proposed for the site . There is no proposed or existing screening . A temporary 4 - foot - high barbed wire chain link security fence will be installed around the Cervi Yard during construction . The perimeter fence will be removed following construction . The Pathway route through Weld County is collocated along existing transmission infrastructure and county roads to reduce visual impacts . The type of steel used will be weathering steel that oxidizes to resemble a natural brown look and is not shiny . Visual impacts of the transmission line will vary based on proximity and with distance , the scale of the transmission poles will be minimized . The visual landscape along the route features existing transmission lines , roadways , and industrial elements , and Pathway will result in an incremental increase in infrastructure in the viewshed . n . Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the activity . Once construction has been completed for each Pathway segment , temporary work areas and the transmission line ROW will be restored in a manner generally similar to their condition prior to construction and as may be provided for in private agreements . This work may include drain the and fence repair , rut removal , decompaction , tilling , COLORADO ' S POWER PATHWAY 44 seeding and stabilization measures . Areas not needed for ongoing operations and maintenance and not being used for crop production will be reclaimed and / or reseeded as soon as practicable and in coordination with the landowner following construction in a given area . If any loss or damage occurred to crops or other non - restorable property during construction , Xcel Energy will compensate the landowner for such loss or damages . ROW agents will meet with landowners to learn about site - specific circumstances , which may need to be addressed . o . Describe the proposed fire protection measures . Transmission lines are built and maintained to meet or exceed safety standards , such as those specified by the National Electrical Safety Code and the North American Electric Reliability Corporation . Every effort is made to ensure safety in construction , operation , and maintenance of transmission lines . Transmission lines are designed to withstand extreme weather conditions , and protective devices at line terminals stop the electricity flow under abnormal operating circumstances . The transmission poles will be equipped with shield wires above the energized line ; this equipment adds to the pole height but also provides protection against lightning strikes . Xcel Energy ' s facilities are designed , constructed , operated , and maintained to meet or exceed all applicable requirements of the IEEE standards and accepted industry standards and practices including IEEE 979 , Guide for Substation Fire Protection . Applicable fire laws and regulations as outlined in CRS 31 - 15 - 601 will be observed during construction and normal operation of the transmission line . Fires along transmission lines are very rare . Xcel Energy ' s facilities are monitored and controlled remotely from an operations center where event response is coordinated . In the rare event of an emergency , Xcel Energy will likely be aware of an issue before the general public or emergency responders . Nevertheless , the public is encouraged to contact Xcel Energy ' s emergency number : 800 - 895 - 1999 to report an emergency . Unauthorized personnel , including emergency responders , should not approach the facilities and should not touch the electric lines or anyone or anything in contact with them . In the event of an outage or transformer failure , the affected equipment is immediately de - energized by the breaker equipment and Xcel Energy personnel are dispatched to the site . Xcel Energy personnel receive safety training for emergencies relating to high - voltage electrical equipment . Xcel Energy also coordinates closely with local fire departments and first responders and consults with them to discuss any concerns within their response area . Xcel Energy offers free online safety training to fire departments and first responders that is based on national standards through the Responding to Utility Emergencies Program . COLORADO ' S POWER PATHWAY 45 2 . Explain how this proposal is consistent with the Weld County Comprehensive Plan . P athway is compatible with the future development of the surrounding area and directly aligns with many of the County Comprehensive Plan goals provided in Chapter 22 of the Weld County Code . P athway will not directly cause significant changes in land use intensity or development in the immediate area . Aside from the transmission pole foundation footprint , areas under and around Pathway facilities can continue to be used for agricultural operations after construction has been completed ( see Attachment P , Agricultural Lands Map ) . After construction , current uses adjacent to Pathway will be able to continue and preserve desirable community and rural patterns meeting goal 22 - 2 - 30 ( A ) ( 2 ) of the Weld County Comprehensive Plan . P athway facilities have been sited to minimize surface - use impacts on the surrounding community and preserve land for agriculture , rangelands , wetlands , and critical habitat areas . As such , Pathway is in alignment with goal 22 - 2 - 30 ( C ) ( 2 ) of the Weld County Comprehensive Plan . Xcel Energy acknowledges that there are local economic benefits when multiple businesses collocate and combine operations and technology . Pathway encourages agglomeration economies of synergistic businesses directly related to goal 22 - 2 - 40 ( A ) ( 5 ) of the Weld County Comprehensive Plan . Encouraging the development of new technologies in Weld County is essential to ensuring its economic prosperity . The Eastern Plains region of Colorado is one of the nation ' s best areas for wind and solar energy generation , but it does not currently have a network transmission system that can integrate these new generation resources into the state ' s interconnected grid system , which is needed to meet Colorado ' s clean energy goals . Pathway will support Xcel Energy ' s Clean Energy Plan ( Xcel Energy 2021 ) which is estimated to deliver as much as an 85 percent reduction in carbon dioxide emissions by 2030 and add approximately 5 , 000 megawatts of new wind , solar , and other resources . Pathway will help to meet the state ' s growing electricity needs , improve safety , reliability , and affordability , and enable the transition to clean energy . P athway will allow developers of energy generation projects to interconnect energy resources located in the areas of the state that are underserved by backbone transmission lines and allow Xcel Energy to deliver energy to electric customers . P ee Attachment K for more details as to how Pathway aligns with each specific Weld County Comprehensive Plan goal . COLORADO ' S POWER PATHWAY 46 3 . Explain how this proposal is consistent with the intent of the zone district ' n which 1 is located . ( Intent statements can be found at the beginning of each zone district section in Article III of Chapter 23 . ) The Pathway facilities subject to this Application are located in unincorporated Weld County within the A ( Agricultural ) Zone District . Pathway has been sited to minimize surface - use impacts to the surrounding community and preserve land for agriculture , rangelands , wetlands , and critical habitat areas . By working with individual landowners , collocating the transmission line route , or strategically locating the route adjacent to other existing public infrastructure improvements or property lines , the Pathway alignment has minimized the impacts to adjacent agricultural uses ( see Attachment P , Agricultural Lands Map ) . Once in operation , Pathway will not create adverse impacts to the existing agricultural u ses resulting from uncontrolled and undirected business , industrial , or residential land u ses . The transmission line will be unstaffed and monitored remotely 24 / 7 / 365 . Xcel Energy ' s transmission lines are normally inspected annually to check for line connections and damage . During construction , minimal permanent impacts to natural resources or agricultural lands will occur . After construction , lands can continue in agricultural use , with the exception of the footprint of the individual transmission poles . As part of the land rights process , Xcel Energy will identify easements or ROW for other u tilities , canals , or roads . Pathway will not cause any undue interference with existing mineral extraction , easements , or ROW during construction and operation . Pathway will enhance the socioeconomic environment in Weld County during the construction period via increased revenue to local businesses and social services . Construction will require contract labor , and provide local jurisdictions and host communities with additional tax revenues and potential employment opportunities . Once in operation , Pathway may facilitate ongoing job opportunities and tax revenue in energy that ultimately interconnects to Pathway . Additionally , generation developers will have the opportunity to build projects that otherwise were infeasible due to lack of transmission access to market and / or transmission constraints . These generation projects may provide other additional economic development through increased jobs associated with construction and local tax - based revenue associated with land usage , and payments to existing landowners . COLORADO ' S POWER PATHWAY 47 4 . Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected munic ' palities . P athway will be compatible with future development of the surrounding area because it has been sited to minimize surface - use impacts to the surrounding community and preserve land for agriculture , rangelands , wetlands , and critical habitat areas . P athway will allow developers of energy generation projects to interconnect energy resources located in the areas of the state that are underserved by backbone transmission lines and allow Xcel Energy to deliver energy to electric customers . Encouraging the development of new technologies in Weld County is essential to ensuring its economic prosperity . Pathway will support Xcel Energy ' s Clean Energy P lan ( Xcel Energy 2021 ) which is estimated to deliver as much as an 85 percent reduction in carbon dioxide emissions by 2030 and add approximately 5 , 000 megawatts of new wind , solar , and other resources . Pathway , while not located within any municipal jurisdiction within Weld County , will help to meet the state ' s overall growing electricity needs , improve safety , reliability , and affordability , and enable the transition to clean energy . See also the response to Planning Question 3 . 5 . xplain how this proposal complies with Article V and Article XI of Chapter 23 if the proposal is located within any Overlay Zoning District ( Airport , Geologic Hazard , or Historic Townsites Overlay Districts ) or a Special Flood Hazard Area identified by maps officially adopted by the County . P athway is not located in any airport , geologic hazard , or historic townsites overlay districts . The Pathway alignment subject to this Application will cross two Federal Emergency Management Agency - designated 100 - year floodplains within unincorporated Weld County associated with the Box Elder / No Name Creek and Lost Creek ( see Attachment L ) . Prior to construction , Xcel Energy will obtain Floodplain Development P ermits from Weld County for crossing these floodplains . 6 . If the proposed use is to be located in the A ( Agr ' cu tural ) Zone District , expla ' n your efforts to conserve pr ' me agricultural and in the locationa decision for the proposed use . Construction and operation of Pathway will not inhibit agricultural production or operations . Pathway will result in minimal permanent impacts to agricultural lands ( see Attachment P , Agricultural Lands Map ) . Through private agreements with individual landowners , the proposed alignment spans existing irrigation ditches and pivot irrigation COLORADO ' S POWER PATHWAY 48 in fields . It is sited to run adjacent to and parallel with section lines , parcel boundaries , and public ROW to limit impacts from the development on overall agricultural operation and production in the area . During construction , temporary impacts to agricultural activities are expected to be minor . Xcel Energy will avoid the removal of ground cover where possible . Disturbed areas will be revegetated following construction . Disturbed areas will be returned to pre - construction conditions or reseeded according to landowner requests and Weld County requirements . Agricultural use can continue for these lands except the footprint of each transmission pole . Permanent Pathway facilities will be limited to the footprint of the individual transmission poles and transmission access roads ( see Section 1 . 4 of this Application ) . 7 . Explain whether this proposal interferes with the protection of the health , safety and welfare of the inhabitants of the neighborhood and the County . By working with individual landowners , obtaining , and meeting applicable federal state and county permits , collocating the transmission line route , or strategically running the route adjacent to other existing public infrastructure improvements , the Pathway alignment mitigates and minimizes to the furthest extent possible the impacts to the health , safety , and welfare of the adjacent agricultural inhabitants . Pathway will not affect wetlands or critical habitats in Weld County . Sensitive natural resource areas , including wetlands and critical habitats for wildlife , were specifically considered as part of the routing and siting analysis when the preferred location for the transmission line was identified to minimize potential interference from Pathway facilities ( see Attachment B , Routing and Siting Study for Segment 1 ) . Xcel Energy has communicated with CPW and USFWS representatives regarding Pathway and will continue to coordinate with them throughout design and construction of Pathway and comply with applicable regulatory requirements .

Describe the expected travel routes for site traffic . Construction traffic will utilize two laydown yards for deliveries of construction materials and equipment : the Sarchet Yard and Cervi Yard . Construction activities in the eastern half of the proposed transmission corridor will utilize the Cervi Yard and construction activities in the western half of the proposed transmission corridor will utilize the Sarchet Yard . • Cervi Yard : East - west - bound Interstate Highway 76 ( 1 - 76 ) : Construction traffic will access the Cervi Yard from I - 76 via the I - 76 frontage road . COLORADO ' S POWER PATHWAY 52 • Sarchet Yard : North - south - bound Colorado Highway 85 : Construction traffic will access the Sarchet Yard via Weld County Road 32 . Daily construction crew traffic will likely access Weld County Road 32 from Highway 85 near Platteville . Once construction has commenced , traffic will originate from both the Cervi and Sarchet yards and will travel along the following Weld County Roads to access the transmission line ROW : 18 , 20 , 22 , 23 , 26 , 28 , 30 , 32 , 33 , 39 , 43 , and 49 . The portions of these roadways utilized will be those Weld County Road segments west and north of the 1 - 76 corridor and east of the U . S . Highway 85 corridor . During construction , the total traffic volumes accessing Weld County Roads are estimated at 50 percent from the Cervi Yard and 50 percent from the Sarchet Yard . However , when construction is concentrated in the western half of the transmission line corridor , traffic volumes are estimated at 75 percent from the Sarchet Yard and 25 percent from the Cervi Yard . When construction is concentrated in the eastern half of the transmission line corridor , traffic volumes are estimated at 75 percent from the Cervi Yard and 25 percent from the Sarchet Yard . During foundation installation , a portion of daily truck traffic will deliver concrete directly to the ROW , without an interim trip to a laydown yard . d .

S S oil information was obtained from Natural Resources Conservation Service ( NRCS ) Websoil S urvey . Cervi Yard project area consists of Hydraulic Soil Groups Type A , Valent Sands with 0 to 3 percent slopes . Infiltration rates for the site were obtained from NRCS . This soil could infiltrate at a high rate of 29 . 97 inch per hour . See Appendix C for NCSS soil maps . Existing Conditions In existing conditions , Basin E2 and E2 . 1 consists of native vegetation . Runoff flows southeast to northwest . The project is south of 1 - 76 Frontage RD . A roadside ditch is just south of 1 - 76 Frontage Rd , but the ditch is very flat . A gravel road runs just west of the project site from north to south from 1 - 76 Frontage Rd to the Burlington Northern Railroad . P roposed Conditions In proposed conditions , drainage patterns will remain the same . For Basin P2 , there will be two entrances to the site along 1 - 76 Frontage Rd . Both will entrances will be via aggregated surfaced . Proposed imperviousness will increase by 3 acres of gravel using the WCECC impervious value of 40 % . An onsite stormwater filled swale will be placed along the north side of the project to collect site runoff . An infiltration pond is proposed on the west side of the project site and will collect all site runoff . A berm will be placed on the along the north side of the site to prevent flows from the roadside ditch to enter or overflow into the site . Design Discussion Infiltration Pond & Spillway Design The proposed infiltration pond was located such that the entire gravel pad is approximately 2 . 0 ' above the 100 - year , 24 - hour duration water surface elevation . This will prevent flooding in the site during a rainfall event . The second method in the WCEC was used for calculating the infiltration pond volume . The infiltration pond was sized 2 . 0 times the developed site runoff of the 100 - year . 24 - hour storm event plus 1 additional foot of freeboard . Due to grading constraints , the volume of the pond will be sized 0 . 5 times larger than the WCEC requirement and will not have an outlet structure or spillway . The bottom of the pond was sized large enough to infiltrate 29 . 97 in / hour or higher and will release 97 % of all runoff from a rainfall event that is less than or equal to the 5 - year storm of 0 . 34 acre - feet within 72 hours after the end of the hdrinc . com 1670 Broadway Suite 3400 Denver , CO 80202 Weld County PWAY Segment 1 — Fort Saint Vrain — Cervi Yard 1r T , Drainage Design Memo event .
