(Tri-State) to request review of the proposed Keota-Redtail 115-kilovolt (kV) Transmission Line Project under the provisions of the Weld County 1041 process. This submittal includes the purpose and need and description of the proposed Project, which is situated on privately owned property in Weld County. Who is Tri-State? Tri-State is a wholesale electric power supplier owned by the 44 electric cooperatives that it serves. Tri-State generates and transports electricity to its member systems throughout a 200,000-square-mile service territory across Colorado, Nebraska, New Mexico, and Wyoming . Tri-State was founded in 1952 The Cooperative Difference and today supplies power for Electric cooperatives are private, not-for-profit utilities approximately 1 .4 million consumers in the owned and governed by the members they serve. four states. Tri-State serves its member Electric cooperatives bridge the vast expanse of rural systems through a combination of owned America to energize residences, farms, ranches, base load, intermediate, and peaking businesses, and communities that have organized power plants that use coal and natural gas cooperatively and accept the responsibility for as their primary fuels, supplemented by delivering safe, affordable, and reliable power. purchased power, federal hydroelectricity allocations, and renewable energy. PROJECT DESCRIPTION Tri-State is proposing to construct a new 345/115-kV substation , called the Keota Substation, to establish a new delivery point for two of its Member Systems, High West Energy and Morgan County Rural Electric Association (REA). The Keota Substation will be located in rural Weld County, south of Grover, Colorado, and will connect to Missouri Basin Power Producer's (MBPP) existing 345-kV transmission line that brings power from the Laramie River Station in Wyoming to the Story Substation in Morgan County, Colorado. The project will also include a new single-circuit 115-kV transmission line that will run from the new Keota Substation to a new 115/69/34.5-kV substation located approximately 24.7 miles northeast of the Keota substation , and referred to as the Redtail Substation. The Redtail Substation is primarily intended to serve a new gas processing plant owned by Whiting Petroleum (Whiting), called the Redtail Gas Plant. High West Energy will construct a distribution line (< 115-kv, and as defined in Section 23. 1 .90 of Weld County Code) from the Redtail substation to Whiting's gas plant, not included as part of this Project, and a use allowed by right in the Agricultural Zone District. Similarly, a distribution substation for Morgan County REA will be constructed either on the proposed Keota substation property or on an adjacent parcel to the southeast, owned by Noble Energy (Noble), where an oil and gas processing facility is currently under construction . 1 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application The substation and transmission line construction would begin in 2014 and the facilities are expected to be in-service by early 2015. The proposed transmission line will be approximately 24.7 miles in length and located entirely on private and state lands. The new transmission line will be primarily H-frame construction using wood structures. Five poles coming out of the Keota substation would be steel , and double-circuit, if the Morgan County REA distribution substation is located on the Noble site. The project will also include construction and operation of a 260-foot communication tower, located at the Keota substation . The communication tower will provide remote power system control at the Keota and Redtail substations through high speed digital communications between Tri-State's operation centers in Westminster and Frederick, Colorado and the regional communication hub located in Brush , Colorado. PURPOSE AND NEED Tri-State is the wholesale provider of electrical energy to its Member Systems, High West Energy and Morgan County REA, who provide retail electrical service to their customers in northeastern Colorado, Wyoming, and Nebraska . Both Member Systems received formal requests to serve developing oil and gas loads in their service territories, and both are obligated to provide this service. The sole purpose of the proposed facilities is to serve High West Energy and Morgan County REA customers. Whiting is currently constructing a gas processing plant located near County Roads (CR) 127 and 116, and received approval from the Weld County Board of County Commissioners on August 6, 2013 for the Redtail Gas Plant (USR13-0016). The facility is proposed to be in- service by December, 2013, and will be electrically powered by the proposed Project in early 2015. Natural gas fired turbine generators will be used in the interim . The Project is also being proposed to serve an oil and gas processing facility being constructed by Noble, adjacent to the new Keota substation. The Noble facility was approved by the Weld County Commissioners on July 10, 2013 (USR13-0013). The Noble facility will use natural gas fired turbine generators until the proposed transmission line is energized in early 2015. The communication tower located at the Keota substation is needed to: provide voice communications for the safety of the personnel working at the substations; provide revenue metering ; remotely communicate with the Supervisory Control and Data Acquisition (SCADA) equipment and transmission line relay protection equipment; and comply with the Federal Energy Regulatory Commission (FERC) mandated security systems for a bulk power substation . ALTERNATIVES TO THE PROPOSED PROJECT Transmission System Alternatives Two electrical system alternatives were evaluated to address the need for the Project. 2 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Alternative A: No Action Taking no action would result in no power delivery to our Members and their customers. The No Action Alternative does not meet the need of the Project. Alternative B: New Substation and 115-kV Transmission Line Connection This alternative would involve the construction of approximately 24.7 miles of 115-kV transmission line between a new 345/115-kV Keota substation and the Redtail substation. Alternative B would provide the necessary power to supply oil and gas facilities in the area, as requested by Member customers. The preferred system alternative is Alternative B. Alternative B meets the Project's purpose and need and provides a cost-effective, secure, and reliable source of power for Tri-State's Members, High West Energy and Morgan County REA, and their customers. Transmission Line Routing Alternatives The process used to identify alternative locations for the 115-kV transmission line began with delineating the Study Area (Figure 1 ). The general location for the substation sites and the transmission line were initially identified based on the location of the oil and gas facilities, interconnection considerations, and existing infrastructure. The locations of these features heavily influenced the area of consideration for the transmission line and substations. An opportunities and constraints analysis was completed for the Study Area to help determine potential routes for the Project. Four potential routes from the proposed Keota substation to the Redtail substation were created based on an opportunity and constraints analysis that included , but was not limited to, the following criteria: • Shortest length between the Keota substation and the Redtail substation • Avoidance of the Pawnee National Grasslands • Avoidance of undisturbed and environmentally sensitive areas • Existing linear corridors • Property lines • Buffers surrounding the Cedar Creek wind farm turbines • Buffers surrounding existing oil and gas wells • Buffers surrounding residences • Buffer zones surrounding military infrastructure A detailed description of the opportunity and constraints analysis is provided in Section 21 -3- 330. B.6, and a summary of the alternatives is provided in Table 1 . Alternative 1 : Under all action alternatives, the Keota substation would be located adjacent to MBPP's existing 345-kV Laramie River to Story transmission line approximately one mile south of CR 106 on CR 89. Under Alternative 1 , the transmission line would then head north along the 3 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application existing 230-kV Cedar Creek-Keenesburg transmission line and follow the route to the north and east until diverting south to the Redtail substation one mile west of CR 127. Alternative 1 consolidates the disturbance with the existing transmission line. Less than one mile of transmission line would be constructed outside an existing corridor, and no new landowners (that weren't impacted by the Cedar Creek lines) would be impacted. The line would be placed within 500 feet of two residences, and would cross four parcels (4 miles) currently encumbered by conservation easements held by the Colorado Cattleman's Agricultural Land Trust (CCALT). Alternative 1 is the longest alternative at 26.7 miles. Alternative 2: Under Alternative 2, the transmission line would follow the existing Cedar Creek-Keenesburg line north and east out of the new Keota substation, but would divert from the existing line approximately 2.4 miles south of where the existing line turns due east. The line would then follow parcel boundaries for 2. 15 miles where it would turn to the northeast to cross the Chalk Bluffs. It would then run north for approximately 0.6 mile before turning due east to CR 382. The line would then follow CRs 382 and 118 to the Redtail substation. Alternative 2 is the shortest with 22.5 miles of transmission line and avoids three parcels (2 miles) of land held in conservation easements, compared to Alternative 1 . However, it creates 14.5 miles of disturbance outside the existing corridor (and crosses 18 new parcels), and comes within 500 feet of three residences. Additionally, it creates a new disturbance corridor across the Chalk Bluffs, approximately 2.3 miles south of the existing crossing . Alternative 3: Alternative 3 follows the existing Cedar Creek-Keenesburg transmission line, except where it cuts through the wind farm at the Cedar Creek substation and then re-connects with the existing line near CR 382. The transmission line would follow parcel boundaries along the diversion as much as possible, but would be located approximately 600-800 feet north of the parcel boundaries for approximately 2.8 miles to avoid wind turbines. Alternative 3 would include 25.3 miles of transmission line and would impact nine parcels in conservation easements (5.9 miles). This alternative would create 5.2 miles of new disturbance outside the existing corridor, but would not come within 500 feet of residences. Alternative 4: Alternative 4 occurs entirely outside of the existing Cedar Creek-Keenseburg transmission line corridor. It follows the parcel boundaries east out of the Keota substation for approximately one mile where it turns due north for one mile then back east for seven miles to the approximate alignment of the extension of WCR 105. It then turns north for 1 .25 miles, then east for approximately seven miles to the east side of WCR 119. It then turns north for one mile to the north side of WCR 110. It then turns east and north along property boundaries for approximately 4 miles, then runs north for another 3 miles and terminates at the Redtail substation site. 4 I _ _ I n• �_ •.Y _ tea , . . - \ '' .i l. i .1.

It would cross 30 parcels, none of which have previously been impacted by a transmission line, but many of which are currently under oil and gas development. There would be no disturbance to any parcels currently held in conservation easements by the CCALT under Alternative 4. Additionally, the line would not come within 0.5 mile of any residences. Alternative 4 would not cross the Chalk Bluffs and would be located approximately two miles to the south of the bluffs at its nearest location. Alternative 4 was selected as the preferred alternative after the following land use and natural resource features were taken into account: • Avoidance of the Chalk Bluffs • Landowner input • Line distance • Conservation easements • Existing disturbance (oil and gas) Table 1 : Alternative Summary Table Criteria Alternative 1 Alternative 2 Alternative 3 Alternative 4 Length (miles) 26.7 22.5 25.3 24.7 Homes within 500 feet 2 3 0 0 Miles of new disturbance 0.8 14.5 5.2 24.7 (outside corridor) Miles of line across 4.0 2.8 5.9 0 conservation easements Number of parcels crossed 5 4 9 0 in conservation easements PUBLIC OUTREACH Tri-State mailed a letter to all landowners along the four proposed routes explaining the Project and the purpose that it would serve. The letter identified the purpose and location of the proposed project, and requested permission to assess their properties. Recipients were provided with contact information and were invited to call Tri-State with comments or questions about the Project. Tri-State followed up with direct contact by phone or in person with the owner of each potentially affected property. Several owners of parcels that would be crossed by Alternative 1 requested that Tri-State select another route that was not across their land and/or not across Chalk Bluffs. In addition, several of the parcels crossed by Alternatives 1 , 2 and 3 are encumbered by conservation easements held by CCALT. CCALT strongly opposed any route across its conservation easements. Tri-State also consulted with Colorado Parks and Wildlife (CPW) for the Project, which is described in greater detail in Section 21 -3-330. B.7, who also preferred a route that did not cross the Chalk Bluffs. Tri-State did not receive any formal comment letters, or other negative feedback from landowners along the Preferred Alternative. 7 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application As the preferred route was identified , Tri-State staff reached out individually to the landowners whose property would be impacted by that route. Tri-State continues to work with those landowners to minimize and mitigate impacts to their properties. A second letter was mailed to all landowners previously contacted , informing them of the selection of a preferred route and the two alternatives, and again requested input. 8 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application USE BY SPECIAL REVIEW APPLICATION CHAPTER 23, ARTICLE II, DIVISION 4 OF THE WELD COUNTY CODE 23-2-240 . DESIGN STANDARDS. A. An applicant for a Use by Special Review shall demonstrate compliance with the following design standards in the application and shall continue to meet these standards if approved for DEVELOPMENT. 1 . Adequate water service in terms of quality, quantity and dependability is available to the site to serve the USES permitted. Not applicable. The use being permitted is a 115-kV single-circuit transmission line and substations. 2. Adequate sewer service is available to the site to serve the USES permitted. Not applicable. The use being permitted is a 115-kV single-circuit transmission line. There will be no sewer service at either of the substation sites. 3. If soil conditions on the site are such that they present moderate or severe limitations to the construction of STRUCTURES or facilities proposed for the site, the applicant has demonstrated how much limitations can and will be mitigated. The majority of the soils along the transmission right-of-way and the Keota and Redtail substations have low shrink/swell potential. The majority of the soils are not limited for structures. In order to identify and mitigate any concerns associated with the soils at the substation sites, Tri-State performed a geotechnical soils study. The soils study has identified the structural characteristics of the soil and provided recommendations for construction of foundations within the soils. Mat foundations and drilled piers would be used to support structures and equipment within the substations. Appendix C includes a soil report prepared by the Natural Resources Conservation Service (NRCS). See Section 21 -3-330. B . 15—Hydrologic, Atmospheric, Geologic, Pedologic, Biotic, Visual, and Noise Impacts. 4. Adequate fire protection measures are available on the site for the STRUCTURES and facilities permitted. The proposed transmission line is designed with overhead ground wires and grounded towers to protect the system from becoming damaged by lightning . See Section 21 -3-330. B.5.g—Hazards and Emergency Procedures for additional fire protection measures. 5. USES shall comply with the following stormwater management standards: a. Stormwater retention facilities shall be provided on site, which are designed to retain the stormwater runoff from the fully developed site from a one-hundred-year storm or as otherwise required by the Department of Public Works. In the case of a LIVESTOCK CONFINEMENT OPERATION (L.C.O.), wastewater collection, 9 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application conveyance and retention facilities shall be designed and constructed in accordance with the Confined Animal Feeding Operation Control Regulations (5 CCR 1002-19). A range of measures to ensure that the Project does not impact water quality, among other things, is listed in Appendix B, and prior to construction , a Storm Water Permit for Construction Activities would be acquired from the Colorado Department of Public Health and Environment, if required . The Storm Water Management Plan prepared as part of the Storm Water Permit would likely include the use of sediment control measures, covering of exposed soils, and other established Best Management Practices (BMP) that will control runoff. See Sections 21 -3-330. B. 12—Air and Water Pollution Impacts and Control Alternatives, Air Pollution Impact and Control , and 21 -3-330.B. 16-Surface and Subsurface Drainage. b. The drainage facilities shall be designed to release the retained water at a quantity and rate not to exceed the quantity and rate of a five-year storm falling on the UNDEVELOPED site. Construction of the Project would not create runoff in excess of previous site levels and would not adversely affect drainage. There would be no alteration in the pattern or intensity of surface drainage as a result of construction or operation of the transmission line. Drainage from the Keota substation would be directed towards a proposed detention pond located to the southeast of the facilities on the substation property. Drainage from the Redtail substation would also be directed towards a proposed pond located on the east side of the property. The ponds at both substations will drain to historic drainageways by way of proposed outlet structures. The outlet structures will release flows at a rate equal to the 5-year historic flowrate. 6. All parking and vehicle storage shall be provided on the site; parking shall not be permitted within any public right-of-way. An adequate parking area shall be provided to meet the parking needs of employees, company vehicles, visitors and customers. Right-of-way agreements include 100-foot easements purchased from landowners along the transmission alignment. Only a small portion of the transmission line right- of-way would be disturbed for structure installation and vehicle access. See Section 21 -3-330. B.2.b—Access to the Project Area. During construction , all vehicles would be parked at the staging areas on the Keota and Redtail substation properties, and no parking areas would be constructed. See Section 21 -3-330. B.7—Natural and Socioeconomic Environmental Impacts from Construction of the Electric Transmission Line. 10 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 7. The USE shall comply with all the SETBACK and OFFSET requirements of the zone district. This Project is located within the A (Agricultural) Zone District. The minimum setback is 20 feet, and the minimum offset is 3 feet, or 1 foot for each 3 feet of building height, as defined in Section 23-3-50 of the Weld County Code. The minimum setback required for telecommunication antenna towers in the Agricultural zone is 100 percent of the tower height. This Project complies with the setback and offset requirements. 8. The access shall be located and designed to be safe; ingress and egress shall not present a safety hazard to the traveling public or to the vehicle accessing the property. For USES generating high traffic volumes and large number of large, slow-accelerating vehicles, acceleration and deceleration lanes may be required to mitigate a potential traffic hazard. No adverse effects on county roads are anticipated . Access roads would be created off County roads 89 and 118 for the Keota and Redtail substations, respectively. Tri- State has submitted Access Road Permit applications (AP13-00358, AP13-00372) and will comply with all County design standards. All mobile construction equipment would be certified to operate on Interstate highways. There may be short periods of time when traffic would be halted on County Roads 89 and 118 to allow construction vehicles to enter and exit the construction area. No improvements to roads in Weld County would be required . See Section 21 - 3-330. B.7—Natural and Socioeconomic Environmental Impacts from Construction of the Electric Transmission Line. 9. New accesses to public rights-of-way shall be constructed using the following as minimum standards: a. Size of drainage structure—twelve (12) inches in diameter. b. Length of drainage structure—twenty (20) feet. c. Depth of cover over pipe—twelve (12) inches. d. Width of access—fifteen (15) feet. e. Maximum grade of access—fifteen percent (15%). f. Flare radius—twenty (20) feet. g. Depth of surfacing—four (4) inches. Standards exceeding these minimums may be required depending on the type and volume of vehicles generated by the type of USE proposed. Access roads would be created off County roads 89 and 118 for the Keota and Redtail substations, respectively. Access roads would be 25 feet-wide with a minimum inside flare radius of 50 feet. The roads would be designed with a 6 inch section of modified Class 5 road base. Tri-State has submitted Access Road Permit applications and will comply with all County design standards. 11 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 10. Buffering or SCREENING of the proposed USE from ADJACENT properties may be required in order to make the determination that the proposed USE is compatible with the surrounding uses. Buffering or SCREENING may be accomplished through a combination of berming, landscaping and fencing. Not applicable. The proposed Project is a linear transmission line facility and the substations are located in rural areas where adjacent properties are used exclusively for agriculture. 11 . Uses by Special Review in the A (Agricultural) Zone District shall be located on the least prime soils on the property in question unless the applicant can demonstrate why such a location would be impractical or infeasible. Numerous soil types along the transmission line are designated as Prime Farmlands or Farmlands of Statewide Importance. However, placement of the transmission line support structures would not preclude the use of farmland under the suspended transmission line. Approximately 58 acres of Farmland of Statewide Importance and 27 acres of Prime Farmland, if irrigated would be permanently removed from agricultural uses for the substation sites. However, only a small portion of that would be disturbed for the Project. The facilities proposed for the Keota substation occur primarily on soils that are not considered Prime Farmlands. Nearly all of the soils in the vicinity of the Redtail substation are considered Farmland of Statewide Importance and cannot be avoided . The See Section 21 -3-330.B. 15—Hydrologic, Atmospheric, Geologic, Pedologic, Biotic, Visual, and Noise Impacts. B. If the Special Review Permit for a MAJOR FACILITY OF A PUBLIC UTILITY OR PUBLIC AGENCY is approved, the Planning Commission shall arrange for the Department of Planning Services to record the appropriate Facilities Plan, Utility Line or Selected Route Map with the County Clerk and Recorder. (Weld County Codification Ordinance 2000-1 ) Noted . 23-4-830 . STANDARDS FOR TELECOMMUNICATION ANTENNA TOWERS. A. TELECOMMUNICATION ANTENNA TOWERS are allowed as a use by right, accessory uses, or as a Use by Special Review Permit, per the height guidelines below. The height of a TELECOMMUNICATION ANTENNA TOWER is defined as the distance from the finished grade at the TELECOMMUNICATION ANTENNA TOWER base to the highest point of the TELECOMMUNICATION ANTENNA TOWER. Overall TELECOMMUNICATION ANTENNA TOWER HEIGHT includes the base pad, mounting structures and panel antennas, but excludes lightning rods and whip antennas. Zoning Permit for Use by Right or Accessory TELECOMMUNICATIONS Use by Special Review Use ANTENNA TOWER Permit approval required Up to 35 feet in height > 35 feet up to 70 feet in Greater than 70 feet in height height 12 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application The proposed tower will be 260 feet in height, and is therefore included as part of the Use by Special Review Permit application . B. Radial Spacing. TELECOMMUNICATION ANTENNA TOWERS over thirty-five (35) feet high must be located at least one thousand (1 ,000) feet from other TELECOMMUNICATION ANTENNA TOWERS over thirty-five (35) feet high that are capable of supporting TELECOMMUNICATION FACILITIES. Closer spacing between TELECOMMUNICATION ANTENNA TOWERS may be granted through the Use by Special Review process. This radial spacing requirement does not apply to facilities located at designated antenna farms. The proposed tower will be located within the Keota substation site, approximately 1070 feet from CR 89 and at least 1000 feet from the nearest telecommunication tower located at the Noble facility. C. In addition to meeting the Use by Special Review standards set forth in Article II, Division 5 of this Chapter, the applicant shall submit documentation addressing the following standards: 1 . Existing or approved TELECOMMUNICATION ANTENNA TOWERS cannot accommodate the telecommunications equipment planned for the proposed TELECOMMUNICATION ANTENNA TOWER. Tri-State evaluated existing towers in Weld County for possible collocation or as intermediate repeater sites to lower the required Keota tower height, which is described further in Appendix E. These sites were identified using data provided by Weld County, and using the Federal Aviation Administration (FAA) and Federal Communications Commission (FCC) Antenna Registration System database. Only one site, owned by Noble (USR-13-0013), was found to be close enough to be considered in lieu of a new tower. Three additional sites were identified and evaluated as possible intermediate repeater sites. Noble was contacted about possible colocation at their site approximately 1900 feet from the proposed Keota tower. It was determined that their tower, as designed and permitted , would not be able to support Tri-State's antenna requirements. Only the bottom 40 feet of the 70-foot tower is available for Tri-State's equipment and other structures and general topography would interfere with radio signals at this level (see Appendix E). The three sites considered for repeater sites (USR-974, USR-1750, and CUP-42) were dismissed because they would decrease system reliability and would not eliminate the need for a tower at Keota. The use of additional radio paths would require additional FCC transmit frequency pairs to be available in an area that is already very congested . 13 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Therefore, it was determined that there are no nearby communication towers that could defer the construction of a new 260-foot tower to serve the Keota substation . The structure proposed would allow Tri-State to meet Federal requirements for relay protection of a critical substation by providing geographically diverse paths to Point of Rocks and Weldona (Exhibit A—Appendix E). The reduction in system reliability by using intermediate repeater sites does not outweigh the slight reduction in the height of the proposed tower. 2. The TELECOMMUNICATION ANTENNA TOWER shall not constitute a hazard to aircraft. Tri-State submitted a Notice of Proposed Construction with the FAA (Form 7460-1 ) and received a "Determination of No Hazard to Air Navigation" (Appendix E). 3. The TELECOMMUNICATION ANTENNA TOWER shall be placed on the property to contain on site all ice-fall or debris from TELECOMMUNICATION ANTENNA TOWER failure. The proposed tower will be located approximately 275 feet from the nearest property line, which is adequate to contain on site all ice-fall or debris from the tower. 4. The proposed TELECOMMUNICATION ANTENNA TOWER shall be designed and provide for CO-LOCATION. The Board of County Commissioners may revoke permits or other administrative approvals if conditions for approval of a TELECOMMUNICATION ANTENNA TOWER include CO-LOCATION, but: a. The TELECOMMUNICATION ANTENNA TOWER owner is not willing to provide space for other carriers at a fair market rate when it would not impair the structural integrity of the TELECOMMUNICATION ANTENNA TOWER or cause interference. b. The TELECOMMUNICATION ANTENNA TOWER owner modifies the structure in a way to make CO-LOCATION impractical or impossible. c. If approval is revoked, the facility must be removed at the owner's expense. Tri-State agrees to make the proposed tower available for collocation with such entities as government agencies, public safety operations, utilities, and some non-profit organizations that are determined to be capable of meeting Tri-State's security requirements. We do not collocate with "for profit" entities in the majority of cases, but will review all applications for collocation on a non-discriminatory basis. Any tower space that is not in use or reserved for future use by Tri-State will be available for collocation . Acceptable collocators can occupy the unused portion of the tower as long as space is available and the use is within the tower's structural limits. Tri-State currently has sharing agreements with Western Area Power Administration , Basin Electric, Xcel Energy, the State of Colorado and others to use tower and building spaces at our sites. 14 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 5. The TELECOMMUNICATION ANTENNA TOWER shall have the least practicable adverse visual impact on the environment. The tower will be located within the new Keota substation site and adjacent to existing development including a 345-kV transmission line, a 230-kV transmission line, and an oil and gas facility. The tower will maintain a galvanized finish to best reflect the ambient lighting conditions during daylight hours. The tower will not visually impact this environment. 6. The proposed TELECOMMUNICATION ANTENNA TOWER shall not emit radiation that will adversely affect human health. Tri-State calculated the maximum permissible exposure (MPE) limits for the proposed Keota communication tower (Appendix E), and determined that near-field exposure (approximately 33 feet from the base of the tower) on the ground was a fraction (0.00002 mW/cm2) of the FCC limits (FCC 1997) for the general population ( 1 mW/cm2). Far-field exposure (2601 feet from the base of the tower) was nearly zero (0.00000 mW/cm2). 7. The proposed TELECOMMUNICATION ANTENNA TOWER shall be the minimum height needed to accommodate the TELECOMMUNICATION ANTENNA. The minimum height needed for clearance of both the near-path obstructions (adjacent transmission structures and the 20-foot obstruction clearance criteria), and the mid-path terrain obstructions located approximately 5.45 miles from the Keota substation, is 260 feet. The basic structure height needed to clear the existing 345-kV line and structures is 130 feet. A space diversity antenna will require an additional 30 feet of separation, making the structure 160 feet, plus an additional 10 feet for mobile radio and a lightning rod . The remaining 90 feet is required to clear the topographical features in the area. 8. The proposed TELECOMMUNICATION ANTENNA TOWER shall comply with all applicable federal and State regulations. The proposed tower will comply with FAA regulations, 14 CFR Part 77—Safe, Efficient Use, and Preservation of the Navigable Airspace, and FCC regulations-47 CFR Part 17.4—Antenna Structure Registration . There are no applicable state regulations in Colorado. 9. The design of the proposed TELECOMMUNICATION ANTENNA TOWER shall insure structural integrity. The tower will be designed to current ANSI TIA-222-G-2005 tower design structures to insure structural integrity, among other things. 15 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 10. The proposed TELECOMMUNICATION ANTENNA TOWER shall have adequate measures to discourage unauthorized climbing and to insure the security thereof. The tower will be located within the fenced and locked Keota substation site with adequate security to discourage unauthorized access. No part of the substation will be open to, or accessibly by, the general public. 11 . All reasonably possible sites for the TELECOMMUNICATION ANTENNA TOWER have been considered, and the proposed site is the most appropriate, available site from a land use perspective. The tower will be located within the footprint of the proposed Keota substation . This location is the most suitable to avoid additional disturbance to nearby areas from construction of the tower and/or cable from the tower to the substation. The site currently includes an existing 345-kV and 230-kV transmission line, and will be adjacent to an oil and gas processing facility. 12. The proposed TELECOMMUNICATION ANTENNA TOWER shall not adversely impact wildlife. Tri-State has consulted with CPW for the Project. Impacts to mammals from the tower would be minimal given the existing land use in the area and the proposed fencing around the substation . Disturbance to mammals would primarily include avoidance of the area during the temporary construction activities. Impacts to birds from communication towers are primarily related to steady-burning strobe lights and guy wires (Gehring and Kerlinger 2007a, 2007b), neither of which is required by the FAA at the Keota site. Tower heights lower than 400 feet are not typically associated with bird fatalities (Kemper 1996). Additionally, the tower has been sited to avoid habitats where birds congregate such as wetlands and ponds, and migratory pathways. 13. A Decommissioning Plan. Adequate financial assurance to cover the decommissioning of the facility may be required as a condition of approval of the Decommissioning Plan. The tower is able to be fully decommissioned when no longer needed to provide communication services. All equipment shelters and cabinets are fully removable and foundations are shallow slabs easily demolished and recycled . The tower structure would likely be deconstructed, then sold or reused elsewhere. The land immediately surrounding the tower could be returned to agricultural use following decommissioning, provided it is concurrent with the decommissioning of the substation, as the tower is located within the fenced substation property. 16 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application D. TELECOMMUNICATION ANTENNA TOWER and Equipment Setbacks. 1 . TELECOMMUNICATION ANTENNAS, ATTACHED and other appurtenances may encroach up to two (2) feet into the minimum building setbacks in the underlying zoning district but must not extend over property lines. Not applicable. 2. Minimum setbacks for TELECOMMUNICATION ANTENNAS, CONCEALED are the same as the minimum building setbacks in the underlying zoning district. Not applicable. 3. Minimum setbacks for TELECOMMUNICATION ANTENNA TOWERS are as follows: a. From property lines of properties in the A, C, I and PUD (with Commercial or Industrial uses) zones: one-hundred percent (100%) of the TELECOMMUNICATION ANTENNA TOWER HEIGHT but not less than minimum building setbacks in the underlying zone district. The proposed 260-foot tower will be setback a minimum of 275 feet from the nearest property line. 4. Guy wires and equipment buildings and cabinets. No part of the TELECOMMUNICATION ANTENNA TOWER system, including any guy wire anchors, shall extend closer than thirty (30) feet to the property boundary. No guy wires will be required and no part of the tower system will extend closer than 30 feet to the property boundary. E. Equipment Design. 1 . A TELECOMMUNICATION ANTENNA, ATTACHED on a roof may extend up to fifteen (15) feet over the height of the building or structure and may exceed the underlying zoning district height limitation. TELECOMMUNICATION ANTENNAS, ATTACHED mounted on a building or structure wall must be as flush to the wall as technically possible, and must not project above the top of the wall, and must be located, painted and/or screened to be architecturally and visually compatible with the building it is attached to. Not applicable. 2. TELECOMMUNICATION ANTENNA TOWERS should be painted or coated in earth-tone colors that blend, to the extent possible, with the surrounding building and natural environment, unless State or federal regulations require specific colors. The tower will maintain a galvanized finish to best reflect the ambient lighting conditions during daylight hours and to coincide with the galvanized finish on the existing transmission structures. 17 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 3. TELECOMMUNICATION ANTENNA TOWERS must not be artificially lighted unless required by the FAA or other State or federal agency. Security lighting on the site may be mounted up to twenty (20) feet high and must be directed toward the ground to reduce light pollution, prevent offsite light spillage and avoid illuminating the TELECOMMUNICATION ANTENNA TOWER. Tri-State received a "Determination of No Hazard" from the FAA (Appendix E). The exact type of lighting that will be required by the FAA has yet to be determined , but it is expected to consist of pulsing white strobes during daytime hours and a red beacon at night, as requested by Tri-State to minimize impacts to the nearest resident (located > 1 mile from the tower) and to birds. No security lighting will be installed for the tower. Lighting will be provided only for maintenance activities. 4. Equipment buildings must be compatible with the architectural style of the surrounding building environment with consideration given to exterior materials, roof form, scale, mass, color, texture and character. Equipment buildings must be constructed with materials that are equal to or better than the materials of the principal use. Equipment cabinets must be located, painted and/or screened to be architecturally and visually compatible with the surrounding building and natural environment. The equipment building will be 11 '6 x36' FibreBond Concrete with aggregate exterior commonly used for housing communication equipment, and will be compatible with surrounding building environment including the substation and the oil and gas facility. 5. The maximum permissible noise level shall adhere to the maximum permissible noise levels allowed in the underlying zone district as delineated in Section 14-9-30 of this Code. Equipment must not generate noise that can be heard beyond the site. However, this does not apply to generators used in emergency situations where the regular power supply for a facility is temporarily interrupted. It also does not apply to air conditioners or noise made during regular maintenance and upkeep of the facility and site. The Project would be constructed and maintained in accordance with Colorado Revised Statutes 25-12-101 et seq. (Noise Abatement) and Article IX, Section 14-9- 10 et seq. of the Weld County Code. See Section 21 -3-330. B. 15—Hydrologic, Atmospheric, Geologic, Pedologic, Biotic, Visual, and Noise Impacts. F. Base or Accessory Site Design. 1 . Screening and landscaping appropriate to the context of the site and in harmony with the character of the surrounding environment is required when any part of the facility is visible from public rights-of-way or adjacent properties. No screening is proposed , as the tower would be located adjacent to two transmission lines, a substation, and an oil and gas facility. No landscaping is proposed , as the site is not irrigated. 18 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 2. Existing vegetation and grades on the site should be improved or preserved to the extent possible. Only the minimum amount of soils and vegetation necessary for the safe and reliable construction and operation of the tower will be disturbed . 3. Signage at the site is limited to nonilluminated warning and equipment identification signs. This does not apply to concealed antennas incorporated into freestanding signs. No signage is proposed for the facility. 4. TELECOMMUNICATION ANTENNA FACILITIES, except those in the C and I zones, must not include manned offices, long-term vehicle storage or other outdoor storage, or other uses not needed to send, receive or relay transmissions. Noted . G. Abandonment. If the Use by Special Review has not commenced within three (3) years from the date of approval, or is discontinued for a period of three (3) consecutive years, it shall be presumed inactive or abandoned. The COUNTY shall initiate an administrative hearing to consider whether to grant an extension of time to commence the use or revoke the use. If the use is revoked, it shall be necessary to follow the procedures and requirements of this Division in order to reestablish any subsequent Use by Right or Use by Special Review. Upon the determination that the use has been abandoned, the facility owner has ninety (90) days to re-use the facility or transfer the facility to another owner who will re-use it. Evidence of such shall be provided, in writing, to the Department of Planning Services. 1 . Removal of abandoned TELECOMMUNICATION ANTENNA TOWERS shall be addressed in all lease agreements and shall specifically address the duties and obligations of the lessee and its assigns as well as the property owner regarding the removal of TELECOMMUNICATION ANTENNA TOWERS deemed by the County to be abandoned. Not applicable. 2. The applicant or owner shall submit an Improvements Agreement agreeing to remove the improvements as shown in the application, plans, plat and other supporting documents. The agreement shall be made in conformance with the County policy on collateral for improvements. The agreement shall be approved by the Board of County Commissioners prior to commencement of operations, as applicable. (Weld County Code Ordinance 2010-6). Noted . 19 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 23-2-250 . OPERATION STANDARDS. An applicant for a Special Review Permit shall demonstrate conformance with the following operation standards in the Special Review Permit application to the extent that the standards affect location, layout and design of the Use by Special Review prior to construction and operation. Once operational, the operation of the USES permitted shall conform to these standards. A. The operation of the USES shall comply with the noise standards enumerated in Section 25- 12-101 , C.R.S. The Project would be constructed and maintained in accordance with Colorado Revised Statutes 25-12-101 et seq. (Noise Abatement) and Article IX, Section 14-9-10 et seq . of the Weld County Code. See Section 21 -3-330. B. 15—Hydrologic, Atmospheric, Geologic, Pedologic, Biotic, Visual, and Noise Impacts. B. The operation of the USES shall comply with the air quality regulations promulgated by the Colorado Air Quality Control Commission. Construction of the Project is not expected to contribute to the air quality status in the area. There would be no long-term air quality effects associated with routine operation and maintenance of the proposed transmission line and substations. See Section 21 -3- 330.B. 12—Air and Water Pollution Impacts and Control Alternatives, Air Pollution Impact and Control. C. The operation of the USES shall comply with the water quality regulations promulgated by the Colorado Water Quality Control Commission. There would be no direct impacts to water quality associated with the regular operation or maintenance of the transmission line and substations. See Section 21 -3-330. B. 12—Air and Water Pollution Impacts and Control Alternatives, Air Pollution Impact and Control. D. The USES shall comply with the following lighting standards: 1 . Sources of light, including light from high-temperature processes such as combustion or welding, shall be shielded so that light rays will not shine directly onto ADJACENT properties where such would cause a nuisance or interfere with the USE on the ADJACENT properties; and No lighting would be required for transmission line structures. Lighting will be installed throughout the substation yards and mounted on the building exteriors. However, lights are generally only on in emergency situations when maintenance is required during low light conditions. Substation lighting would not cause a nuisance with agricultural uses on adjacent properties. Lighting for the tower is described in Section 23-4-830, E.3 above. 20 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 2. Neither direct nor reflected light from any light source may create a traffic hazard to operators of motor vehicles on PUBLIC or private STREETS and no colored lights may be used which may be confused with or construed as traffic control devices. No lighting would be required for transmission line structures. Lighting will be installed throughout the substation yards and mounted on the building exteriors. However, lights are generally only on in emergency situations when maintenance is required during low light conditions. Substation lighting would not cause a traffic hazard on county roads and no colored lights would be used . Lighting for the tower is described in Section 23-4-830, E .3 above. E. The USES shall not emit heat so as to raise the temperature of the air more than five degrees (5°) Fahrenheit at or beyond the LOT line. The proposed transmission line and substations would not raise the temperature of the air more than five (50) degrees Fahrenheit at or beyond the lot line. See Section 21 -3- 3303.5.g—Hazards and Emergency Procedures. F. Property shall be maintained in such a manner that grasses and weeds are not permitted to grow taller than twelve (12) inches. In no event shall the property owner allow the growth of NOXIOUS WEEDS. Tri-State's Environmental Protection Measures for Construction Projects (Appendix B) contains a description of revegetation and noxious weed control . G. Any off-site and on-site improvements agreement shall be made in conformance with the County policy on collateral for improvements. (Weld County Codification Ordinance 2000-1 ; Weld County Code Ordinance 2007-1 ) Not applicable. 23-2-260 . APPLICATION REQUIREMENTS. A. The purpose of the application is to give the petitioner an opportunity to demonstrate through written and graphic information how the proposal complies with the standards of this Chapter. The following supporting documents shall be submitted as a part of the application except for those items determined by the Director of Planning Services, in writing, or the Board of County Commissioners, on the record, to be unnecessary to a decision on the application: 1 . A statement which explains that the proposal is consistent with Chapter 22 of this Code and any other applicable code provision or ordinance in effect. The Weld County Code, Chapter 22, Comprehensive Plan, has been reviewed and the proposed project is consistent with the intent of the Comprehensive Plan , including Land Use, Environmental Resources, and Natural Resources. See Section 21 -3-330. B.7—Natural and Socioeconomic Environmental Impacts from Construction of the Electric Transmission Line. 21 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 2. A statement which explains that the proposal is consistent with the intent of the district in which the USE is located. The Project area is located within the Agricultural Zone District. Major facilities of public utilities are uses that are allowed by special review within the Agricultural Zone District. See Section 21 -3-330. B.5.a—Present Use and Zoning . 3. A statement which explains that the USES which would be permitted will be compatible with the existing surrounding land USES. Land to the north , east, and west of the Project area is part of unincorporated Weld County and is zoned agricultural. The Cedar Creek Wind Farm is located north of the proposed transmission line route and two oil and gas facilities are located near each of the substations. There is an existing 245-kV transmission line going between the proposed Keota substation and the wind farm. The remainder of the area is largely used for agricultural purposes and oil and gas development. This Project would be compatible with the existing surrounding land uses. See Section 21 -3-330.B.5.m— Existing Land Uses of All Properties Adjacent to Parcel. 4. A statement which explains that the USES which would be permitted will be compatible with the future DEVELOPMENT of the surrounding area as permitted by the existing zone and with future DEVELOPMENT as projected by Chapter 22 of this Code and any other applicable code provision or ordinances in effect, or the adopted MASTER PLANS of affected municipalities. This use is consistent with the future development of the surrounding area as permitted by the existing zoning and as projected by Chapter 22 of this Code. See Section 21 -3-330.B.5.a—Present Use and Zoning . 5. A statement which explains that the application complies with Article V of this Chapter if the proposal is located within any Overlay District Area identified by maps officially adopted by the COUNTY. Not applicable. The Project area is not within an Overlay District Area, as defined in Article V. 6. A statement which explains that if the USE is proposed to be located in the A (Agricultural) Zone District, the applicant has demonstrated a diligent effort has been made to conserve prime agricultural land in the locational decision for the proposed USE. Numerous soil types along the transmission line are designated as Prime Farmlands or Farmlands of Statewide Importance. However, placement of the wood pole transmission line support structures would not preclude the use of farmland under the suspended transmission line. Approximately 58 acres of Farmland of Statewide Importance and 27 acres of Prime Farmland , if irrigated would be permanently removed from agricultural uses for the substations. However, only a small portion of that would be disturbed for the Project. The facilities proposed for the Keota 22 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application substation occur primarily on soils that are not considered Prime Farmlands. Nearly all of the soils in the vicinity of the Redtail substation are considered Farmland of Statewide Importance and cannot be avoided . The See Section 21 -3-330. B. 15— Hydrologic, Atmospheric, Geologic, Pedologic, Biotic, Visual, and Noise Impacts. 7. A statement which explains that there is adequate provision for the protection of the health, safety and welfare of the inhabitants of the NEIGHBORHOOD and the COUNTY. All Tri-State electric facilities are designed, constructed, operated , and maintained to meet or exceed all applicable standards of design and performance set forth in the National Electrical Safety Code (NESC 2012). Health and safety concerns associated with the Project, therefore, would be limited largely to electromagnetic fields (EMF) from the transmission line. EMF was modeled for the project as a function of predicted magnetic field levels, based on typical and peak loads, from the proposed transmission line, and is described in Section 21 -3-330.

B.5.b—d—Map Extent Figure 4 illustrates all existing transmission lines of 115-kV or greater within two miles of the Project site. 21 -3-330. B.5.e—Type of Facility The Project would involve construction of approximately 24.7 miles of new 115-kV transmission line between the new Keota substation and the new Redtail substation. High West Energy would construct the distribution line to Whiting's Redtail Gas Plant, which was approved by the Weld County Board of County Commissioners on August 6, 2013 (USR13- 0016). Morgan County REA would construct the distribution line to the Noble facility, if the distribution substation is built on the proposed Keota property. Construction of a substation on the Noble property was approved by the Weld County Board of County Commissioners on July 10, 3013 (USR13-0013). Both distribution lines (< 115-kV) are considered a use allowed by right in the Agricultural Zone District, and not included in this permit application. The new transmission line would be a single-circuit, 115-kV line constructed primarily on H-frame wooden structures within a 100 foot right-of-way. If the Morgan County REA distribution substation is constructed on the Noble property, approximately five poles would be steel and double-circuit. The transmission line would consist of approximately 124-198 structures, with three conductors and three phase wires, a shield wire, and an optical ground wire for internal Tri-State communications. The project will also include a new 345/115-kV Keota Substation and a new 115/69/34.5-kV Redtail substation located on lands purchased by Tri-State for the Project. The Keota substation will include a 345-kV three breaker ring bus, a 345-115-kV 135/180/225 MVA transformer, and a four breaker 115-kV bus. Both the 345-kV and the 115-kV buses will be designed to be expandable to a breaker and a half, and potential future build-out is shown on Figure 2A. The Redtail substation will include a three breaker 115-kV ring bus, a 115-69-kV 30/40/50 MVA transformer, and a 115-34.5kV 30/40/50 MVA transformer. The 115-kV bus will be designed to be expandable to a breaker and a half, as shown on Figure 2B . Site preparation at both substations will include grading , fencing , grounding, and construction foundations. The project will also include a 260-foot communication tower, located at the Keota substation . The communication tower will include four antennas located at 180/150 feet above ground level (agl) and 240/210 agl, a mobile radio antenna, and a lightning rod . The communication building adjacent to the tower will include a standby emergency generator system and HVAC sized to maintain 77 degrees. 55 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 21 -3-330. B.5.f—Projected Development Schedule A project schedule is presented in Table 5. Table 5: Project Schedule Milestone Date Easement Acquisition April—July 2014 Weld County Permit Granted March 2014 Order Materials Fall 2013 Construction Begins June 2014 In Service January—February 2015 21 -3-330. B.5.g—Hazards and Emergency Procedures The purpose of the proposed transmission facilities is to conduct electricity. The greatest danger from a transmission line is direct contact with electrical conductors. Accordingly, extreme caution must be exercised when operating vehicles and equipment near the Project. The conductors are supported by insulators mounted on grounded poles to prevent arcing (which could start a fire). Tri-State prohibits storage of flammables, construction of flammable structures, and other activities that have the potential to cause or provide fuel for fires on its easements and rights-of-way. There are no explosive substances associated with the proposed transmission line or substations. All Tri-State electric facilities are designed , constructed , operated, and maintained to meet or exceed all applicable standards of design and performance set forth in the NESC (NESC 2012). Post-construction , the proposed transmission line and substations would be unmanned and controlled remotely by Tri-State. Transmission line poles and conductors occasionally may be hit by lightning; therefore, the area near towers and other tall objects (e.g . , trees) should be avoided during thunderstorms. The proposed line is designed with overhead ground wires and grounded towers to protect the system from becoming damaged by lightning. Health and safety concerns associated with the Project, therefore, would be limited largely to EMF from the transmission line and substations. Electric fields are caused by voltage on an object, such as the voltage on conductors connected to an energized substation . Magnetic fields are produced when an electrical current flows through a conductor. EMF extends outward from transmission line conductors and decreases rapidly with distance from the transmission line. The concept of prudent avoidance was considered in the siting and proposed construction , and operation of this facility. The expected levels of EMF for the proposed 115-kV single-circuit transmission line will be at or below 150 mG, as required by the PUC (Rules 3206(e) and (f)). These levels are similar to magnetic fields generated by common household appliances, power tools, and office equipment (Table 6). 56 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Table 6: Common Sources of Magnetic Fields Sources of Magnetic Fields (mG)* Distance from source Distance from source 6" 1 ' 2' 4' 6" 1 ' 2' 4' Office Sources Workshop Sources AIR CLEANERS BATTERY CHARGERS Lowest 110 20 3 - Lowest 3 2 - - Median 180 35 5 1 Median 30 3 — — Highest 250 50 8 2 Highest 50 4 - - COPY MACHINES DRILLS Lowest 4 2 1 - Lowest 100 20 3 - Median 90 20 7 1 Median 150 30 4 - Highest 200 40 13 4 Highest 200 40 6 - FAX MACHINES POWER SAWS Lowest 4 - - - Lowest 50 9 1 - Median 6 - - - Median 200 40 5 - Highest 9 2 — — Highest 1000 300 40 4 FLUORESCENT LIGHTS ELECTRIC SCREWDRIVERS (while charging) Lowest 20 - - - Lowest - - - - Median 40 6 2 - Median - - - - Highest 100 30 8 4 Highest - - - - ELECTRIC PENCIL SHARPENERS Lowest 20 8 5 - Distance from source Median 200 70 20 2 1 ' 2' 4' Highest 300 90 30 30 Living/Family Room Sources VIDEO DISPLAY TERMINALS (see page 48) CEILING FANS (PCs with color monitors)** Lowest - - - Lowest 7 2 1 - Median 3 - - Median 14 5 2 - Highest 50 6 1 Highest 20 6 3 - WINDOW AIR CONDITIONERS Lowest - - - Bathroom Sources HAIR DRYERS Median 3 1 - Highest 20 6 4 Lowest 1 - - - COLOR TELEVISIONS** Median 300 1 - Highest 700 70 10 1 Lowest - - - Median 7 2 - ELECTRIC SHAVERS Highest 20 8 4 Lowest 4 - - - Median 100 20 - - Highest 600 100 10 1 57 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Table 6: Common Sources of Magnetic Fields, continued Sources of Magnetic Fields (mG)* 7 Distance from source Distance from source 6" 1 ' 2' 4' 6" 1 ' 2' 4' Kitchen Sources Kitchen Sources BLENDERS ELECTRIC OVENS Lowest 30 5 — — Lowest 4 1 — — Median 70 10 2 — Median 9 4 — — Highest 100 20 3 — Highest 20 5 1 — CAN OPENERS ELECTRIC RANGES Lowest 500 40 3 - Lowest 20 - - - Median 600 150 20 2 Median 30 8 2 - Highest 1500 300 30 4 Highest 200 30 9 6 COFFEE MAKERS REFRIGERATORS Lowest 4 - - - Lowest - - - - Median 7 - - - Median 2 2 1 - Highest 10 1 - - Highest 40 20 10 10 DISHWASHERS TOASTERS Lowest 10 6 2 - Lowest 5 - - - Median 20 10 4 - Median 10 3 - - Highest 100 30 7 1 Highest 20 7 - - FOOD PROCESSORS Lowest 20 5 - - Bedroom Sources Median 30 6 2 — Highest 130 20 3 _ DIGITAL CLOCK**** GARBAGE DISPOSALS Lowest - - - Median 1 - - Lowest 60 8 1 - High 8 2 1 Median 80 10 2 - Highest 100 20 3 - ANALOG CLOCKS MICROWAVE OVENS*** (conventional clockface)**** Lowest 100 1 1 - Lowest 1 - - Median 200 4 10 2 Median 15 2 - Highest 300 200 30 20 Highest 30 5 3 MIXERS BABY MONITOR (unit nearest child) Lowest 30 5 - - Lowest 4 - - - Median 100 10 1 - Median 6 1 - - Highest 600 100 10 - Highest 15 2 - - 58 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Table 6: Common Sources of Magnetic Fields, continued Sources of Magnetic Fields (mG)* 7 Distance from source Distance from source 6" 1 ' 2' 4' 6" 1 ' 2' 4' Kitchen Sources Kitchen Sources BLENDERS ELECTRIC OVENS Lowest 30 5 — — Lowest 4 1 — — Median 70 10 2 — Median 9 4 — — Highest 100 20 3 — Highest 20 5 1 — CAN OPENERS ELECTRIC RANGES Lowest 500 40 3 - Lowest 20 - - - Median 600 150 20 2 Median 30 8 2 - Highest 1500 300 30 4 Highest 200 30 9 6 COFFEE MAKERS REFRIGERATORS Lowest 4 - - - Lowest - - - - Median 7 - - - Median 2 2 1 - Highest 10 1 - - Highest 40 20 10 10 DISHWASHERS TOASTERS Lowest 10 6 2 - Lowest 5 - - - Median 20 10 4 - Median 10 3 - - Highest 100 30 7 1 Highest 20 7 - - FOOD PROCESSORS Lowest 20 5 - - Bedroom Sources Median 30 6 2 — Highest 130 20 3 _ DIGITAL CLOCK**** GARBAGE DISPOSALS Lowest - - - Median 1 - - Lowest 60 8 1 - High 8 2 1 Median 80 10 2 - Highest 100 20 3 - ANALOG CLOCKS MICROWAVE OVENS*** (conventional clockface)**** Lowest 100 1 1 - Lowest 1 - - Median 200 4 10 2 Median 15 2 - Highest 300 200 30 20 Highest 30 5 3 MIXERS BABY MONITOR (unit nearest child) Lowest 30 5 - - Lowest 4 - - - Median 100 10 1 - Median 6 1 - - Highest 600 100 10 - Highest 15 2 - - 58 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Table 6: Common Sources of Magnetic Fields, continued Sources of Magnetic Fields (mG)* Distance from source Distance from source 6" 1 ' 2' 4' 6" 1 ' 2' 4' Laundry/Utility Sources Laundry/Utility Sources ELECTRIC CLOTHES DRYERS PORTABLE HEATERS Lowest 2 -- - - LONA est 5 1 - - Median 3 2 - - Median 100 20 4 — Highest 10 3 - - Highest 150 40 8 1 WASHING MACHINES VACUUM CLEANERS Lowest 4 1 - - Lowest 100 20 4 - Median 20 7 1 — Median 300 60 10 1 Highest 100 30 6 — Highest 700 200 50 10 IRONS SEWING MACHINES Lowest 6 1 - - Home sewing machines can produce magnetic fields Median 8 1 - - of 12 mG at chest level and 5 mG at head level.

For example, televisions and computer screens produce fields at 10,000-30,000 Hz ( 10-30 kHz) as well as 60-Hz fields. *** Microwave ovens produce 60-Hz fields of several hundred milligauss, but they also create microwave energy inside the appliance that is at a much higher frequency (about 2.45 billion hertz). We are shielded from the higher frequency fields but not from the 60-Hz fields. **** Most digital clocks have low magnetic fields. In some analog clocks, however, higher magnetic fields are produced by the motor that drives the hands. In the above table, the clocks are electrically powered using alternating current, as are all the appliances described in these tables. Source: National Institutes of Health 2002 59 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application The Colorado Public Utilities Commission requires public utilities to weigh potential health effects and the cost of mitigating those effects by using alignments that "limit exposures [of electric and magnetic fields] to areas of concentrated population and group facilities such as schools and hospitals" (4 Code of Federal Regulations [CFR]. 723-3-18(i)(2)) "or by burying transmission lines." This Project maintains suitable distances from such areas. Numerous scientific studies have been conducted to better understand whether there is a possibility that EMF causes disease. The consensus of scientists familiar with these studies is that no significant risk to humans from long-term exposure to EMF has been established . Tri-State remains sensitive to the EMF issue and responds promptly and accurately to inquiries with currently available information . As corporate policy, Tri-State has adopted programs to ensure that its electric facilities are designed , constructed , and operated to minimize, to the extent prudent and practicable, the level of EMF that is created . Tri-State's position statement on EMF health effects is included as Appendix A. Environmental Hazards Enclosed containment would be provided for all trash. All construction waste, including trash and litter, garbage, other solid waste, petroleum products, and other potentially hazardous materials would be removed from the site and transported to a disposal facility authorized to accept such materials. There would be no significant amount of hazardous materials stored in the Project area. Construction , operation , and maintenance activities would comply with all applicable federal, state, and local laws and regulations regarding the use of hazardous substances. The only hazardous chemicals expected to be used on site are those found in diesel fuel, gasoline, coolant (ethylene glycol), and lubricants in machinery. Hazardous materials would not be drained onto the ground or into streams or drainage areas. In its contract with the construction contractor, Tri-State would specify that it will hold a required pre-construction meeting with the contractor to ensure all applicable laws and Tri-State's procedures would be followed . Tri-State's Project Environmental Protection Measures for Construction Projects are attached as Appendix B. Although the transmission line would be inspected annually, emergencies may occur. If there were an issue, appropriate field crews and engineering personnel would be notified by telephone or radio and they would undertake the required procedures to correct the problem and restore facilities to normal operations. 21 -3-330.

There are no residences that occur on parcels adjacent to the transmission line and none within 0.5 mile of the line. No residences occur on parcels adjacent to the substation , but one residence is within one mile of the Keota substation . There are multiple oil and gas wells and an existing transmission line on the properties as well. 21 -3-330. B.5.n—Present Zone and Overlay Zones The current zoning in the Project area is agricultural. The Project site is not situated within the boundaries of a 100-year or 500-year floodplain (Federal Emergency Management Agency 1997). Tri-State has submitted an application with FAA and received a "Determination of No Hazard to Air Navigation" (Appendix E). 21 -3-330.

The opportunities and constraints criteria are provided in Table 7. 62 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Table 7: Opportunities and Constraints Criteria Criteria Opportunity Avoid (if feasible) Exclude Existing Utility and Transportation Corridors Existing transmission Parallel to existing Transmission lines Distribution lines of any lines (69-kV and transmission line corridor with short spans of voltages or overhead above) less 400 feet telephone lines; parallel to lines in areas that have small parcels and where ROW will utilize too much of the parcel Roads (interstate, Within 0.25 mile Overhang of lines Structures within road state, county) over ROW or ROW; exclude highway blowout of conductor interchanges over ROW Pipelines Major pipeline corridors, Pipelines crossing Using any portion of the especially where no cultivated property at pipeline ROW for the cultivation activities occur a diagonal transmission line and the land features are open or have sparse habitation Land Use Agriculture Rangeland or cropland, Prime farmland, Pivot or other mechanical where compatible farmland of irrigation footprint; statewide crossing cultivated lands importance at a diagonal Wind turbines Within 300 feet of structure Oil/gas wells Within 150 feet of required setback Occupied residences Within 500 feet Within ROW Military infrastructure Within 1/2 mile of facilities Water and Natural & Cultural Resources Wetlands Within boundary Surface waters Using existing corridors Within 0. 125 mile of Within 100 feet of where they cross surface perennial streams perennial streams and waters and lakes lakes Habitat for sensitive, Within known Within critical habitat for threatened, or occupied habitat threatened or endangered species endangered species Engineering Concerns Access Use available roads, or Water crossings; if Development of access cross-country access with possible, using that leads to major minimal new access railroad ROW for cutting, filling, culvert development; multiple access installation, etc. (more of existing access points; an issue in mountainous ability to travel along terrain) ROW 63 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Table 7: Opportunities and Constraints Criteria Criteria Opportunity Avoid (if feasible) Exclude Parallel lines Lines having longer Lines with short Lines of 69-kV or lower average spans of 600 spans of less than feet or greater 400 feet Crossings Multiple highway or interstate crossings; multiple crossing of existing transmission lines CFR=Code of Federal Regulations FAA=Federal Aviation Administration FCC=Federal Communications Commission ROW=right-of-way The opportunities and constraints analysis yielded four possible alternative routes for the transmission line. The four alternatives were then compared based on the following: • Number of residences within 100 and 500 feet • Number of oil and gas wells within 150 feet • Number of wind turbines within 300 feet • Number of parcels crossed • Length of transmission line • Miles of new disturbance • Miles of line that does not follow parcel boundaries • Number of drainage crossings • Miles of line across conservation easements • Acres of disturbance to Prime Farmland and Farmland of Statewide Importance • Distance from military infrastructure Based on the comparative analysis and stakeholder (CCALT, landowners, and CPW) input, the preferred route was selected . The preferred route minimizes impacts to natural resources and current land use. 21-3-330.B. 7—Natural and Socioeconomic Environmental Impacts from Construction of the Electric Transmission Line (satisfies 21-3-330. C.2.a) Land Use Land use along the proposed transmission line route would be minimally impacted and would continue to include agriculture and oil and gas activities. Agricultural productivity would be minimally impacted as a result of the Project. The Weld County Code, Chapter 22, Comprehensive Plan , has been reviewed and the proposed transmission line is consistent with the intent of the Comprehensive Plan , including land use, environmental resources, and natural resources. 64 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application The proposed transmission line would be located in an area that is zoned agricultural . Although the transmission line is not an agricultural use, it is a land use commonly located in agricultural areas and does not conflict with the goals outlined in the Comprehensive Plan . Careful site planning would be developed with only a localized loss of agricultural land quality. Ground disturbance generally would be limited to an area of approximately 625 square feet around each pole (25 feet x 25 feet). The long-term presence of the existing 230-kV and 345-kV transmission lines and continued agricultural uses in the area provide an example of the complementary nature of the two uses. Transportation Impacts (satisfies 21 -3-330.C.2.g) Approximately 30 construction workers would be employed during the course of the approximately 8-month construction period . The maximum number of construction workers at any one time would be approximately 30. Table 8 lists the personnel and equipment for each phase of construction . Table 9 lists the weight of construction vehicles. The Project would generate infrequent trips to the transmission line and substations during operation ; the line would be inspected annually and occasionally for maintenance. No adverse effects on county roads are anticipated . Tri-State would work with the Weld County Public Works Department to determine the appropriate access to the construction area. All mobile construction equipment would be certified to operate on Interstate highways. There may be short periods of time when traffic would be halted on CRs 89 and 118 to allow construction vehicles to enter and exit the construction area. No improvements to Weld County roads would be required.

According to the U .S . Census Bureau (2010), the population of Grover was approximately 137. Larger nearby cities include Greeley (35 miles to the southwest) and Cheyenne (36 miles to the northwest). It is anticipated that the Project would have a negligible impact to the community of Grover, as there are no gas stations, restaurants, or hotels. The project may have a small beneficial impact to the local economy of Greeley and other small communities located between the Project area and metropolitan areas such as Cheyenne and Denver. Construction contractors, regardless of origin , would likely spend some money in Cheyenne or Greeley for fuel, food , or other supplies. During the construction period, the local economy may see a small influx of dollars and a small increase in sales tax revenue. The footprints of the proposed structures would be the only land removed from current use. Land between the transmission structures would remain available for farming , grazing , or other operations that do not interfere with safe and reliable operation of the transmission line. The Project area is located within District 1 of the Weld County Sheriffs Department and is within the jurisdiction of the Pawnee Fire Protection District. Public roads are maintained by the Weld County Department of Public Works. The nearest hospital is the Northern Colorado Medical Center, located in Greeley. None of these services is expected to be affected , unless emergency situations occur. There are no adverse socioeconomic impacts associated with the Project. The Project would not cause any residents or businesses to be displaced . The Project would generate additional tax revenue for Weld County. This Project is not inconsistent with the Economic Development Goals and Policies described in the Weld County Comprehensive Plan (Weld County 2008). 66 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Discussion of Impacts on Additional Resources Including Significant Environmentally Sensitive Factors ;satisfies 21 -3-330.C.2c and 21 -3-330.C.2e) Vegetation Including Marshlands and Wetlands The vicinity of the Project site is characterized by agricultural uses, primarily farming and ranching . The surrounding vegetation communities can be characterized as disturbed grassland. Permanent removal of vegetation would occur at structure sites. Construction would occur primarily in an area that has been previously disturbed, and impacts to native vegetation communities are expected to be minimal. Most access would be overland in nature or along existing roads, and minimal vegetation would be disturbed from roads. The preferred alternative transmission line route would cross three named-drainages, Wild Horse Creek, Igo Creek, and North Pawnee Creek. The drainages would likely be spanned by the transmission line so no impacts would occur. Neither wetlands nor wetland vegetation was observed in association with the drainages. Additionally, no drainages or wetlands occur at either of the substation sites. Figure 7 presents a map of water resources within two miles of the Project site. If it is later determined that the drainages cannot be spanned and temporary impacts to wetlands would occur, Tri-State would notify the Army Corps of Engineers and construction would be authorized under a Nationwide Permit. Impacts to vegetation are expected to be minimal and impacts to wetlands and water resources are not expected to result from the Project. Wildlife and Critical Wildlife Habitat The native grassland and agriculture areas surrounding the transmission line are likely to support a variety of common wildlife such as pronghorn , coyote, fox, skunk, rabbits, and various birds. There is no designated critical wildlife habitat in the vicinity of the project. The area also supports habitat for various state-listed species, discussed in detail below. Tri-State is conducting an assessment of the area to identify suitable habitat, particularly for special status species. Additional surveys will be conducted in the spring , prior to construction , in areas identified as suitable habitat for state-listed species and for migratory birds. CPW recommended species-specific surveys for Plains Sharp-tailed Grouse leks, Mountain Plover, and Western Burrowing Owls (if prairie dog towns are found). If any nests for migratory birds or any state-listed species are found , appropriate construction timing limitations will be enforced, as feasible, according to CPW recommendations. Where timing limitations or setback cannot be applied due to timing constraints, other alternative mitigation measures would be considered and vetted with CPW. Project impacts to wildlife are expected to be minimal and limited to temporary disturbance from construction activities. The selection of the Preferred Alternative helped to eliminate potential disturbance to sensitive species found around the Chalk Bluffs. To preclude avian electrocutions and minimize collision risk, Tri-State would incorporate Avian Protection Plan (APP) standards developed by the Avian Power Line Interaction Committee (APLIC 2006) and the APP guidelines (APLIC and U .S. Fish and Wildlife Service 67 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application [USFWS] 2005) to protect birds on power lines, as well as NESC-specified electric conductor clearances. Special Status Species Federally threatened or endangered species that occur in Weld County are listed in Table 10. Table 10: Threatened or Endangered Species in Weld County Common Name Scientific Name Federal Status State Status Birds Mexican Spotted Owl Strix occidentalis lucida Threatened Threatened Least Tern Sternula antillarum Endangered Endangered Piping Plover Charadrius melodus Threatened Threatened Whooping Crane Grus americana Endangered Endangered Western Burrowing Owl Athene cunicularia Threatened Bald Eagle Haliaeetus leucocephalus Special Concern Plains Sharp-tailed Tympanuchus Endangered Grouse phasianellus jamesii Mammals Black-footed Ferret Mustela nigripes Endangered Endangered Preble's Meadow Zapus hudsonius preblei Threatened Threatened Jumping Mouse Plants Colorado Butterfly Plant Gaura neomexicana spp. Threatened coloradensis Ute Ladies'-tresses Spiranthes diluvialis Threatened orchid Source: USFWS 2013 The USFWS list of federally threatened or endangered species includes six wildlife species and two plant species in Weld County: the Mexican Spotted Owl, Least Tern , Piping Plover, Whooping Crane, black-footed ferret, Preble's meadow jumping mouse, Colorado butterfly plant, and Ute ladies'-tresses orchid. The Mexican Spotted Owl is known to occur in the southwestern U .S. with the main populations inhabiting Arizona and New Mexico. The Mexican Spotted Owl prefers canyon habitat consisting of mixed-conifer, pine-oak, and riparian forest. This habitat is not present in the Project area. Therefore, Mexican Spotted Owls are unlikely to be impacted by the Project. The Least Tern and Piping Plover are typically found near water. Terns are fish eaters and prefer to nest on sandy or pebbly beaches around lakes and reservoirs, or on sandbars consisting of sandy soils in river channels. Piping Plovers feed on a variety of beach-dwelling invertebrates and nest on sandy lakeshore beaches, sandbars within riverbeds, or even sandy wetland pastures. Given the lack of water and the intense agricultural land use, these two species are not expected to occur in the Project area. 68 _ - - • I , \I„ . a ` Jilli• Tri- State Generation and �- ,. y Id - r` Transmission Association , Inc . i P.

This population uses the Central Flyway to migrate across Texas, Oklahoma, Kansas, Nebraska, South Dakota, North Dakota, and eastern Montana. Whooping cranes are listed by the USFWS for Weld County as a potentially impacted species due the potential depletion of the Platte River Basin. The USFWS considers projects with less than 0. 1 acre-foot per year of depletion to be de minimis exceptions for water-related activities in the Platte River Basin . The proposed Project may use water for dust abatement activities during construction ; however, water use will be below the de minimis threshold for depletion . No impacts to Whooping cranes are anticipated for this Project. The black-footed ferret is the rarest mammal in North America ; there are no surviving wild , unmanaged populations. This animal is an obligate predator of prairie dogs and , as a general rule, cannot survive in the absence of large prairie dog colonies. There are two populations of black-footed ferrets in Colorado (both re-introduced): one west of Rangely near the Utah border, and one southeast of Dinosaur National Monument (Colorado Parks and Wildlife [CPW] 2011 ). Re-introduced ferrets in Wyoming are located in Shirley Basin , between Medicine Bow and Casper (Wyoming Game and Fish Department 2011 ). A prairie dog colony was observed in only one location along the proposed right-of-way during initial reconnaissance, and fall habitat assessments are expected to confirm these results. Impacts to the black-footed ferret are not expected from the Project. The Preble's meadow jumping mouse is a federally threatened species in Colorado. This species inhabits riparian areas and adjacent uplands. Preferred riparian habitat includes mixed vegetation types where dense herbaceous or woody vegetation occurs near the ground level and where available open water exists during their active season . Presence of this species along the proposed route is highly unlikely. There is no suitable habitat or designated critical habitat for Preble's meadow jumping mouse in or near the Project site; therefore, no impacts to the species are expected. The Ute ladies'-tresses orchid and Colorado butterfly plant are federally threatened plant species associated with floodplains and wet meadows. The Project site does not support suitable habitat, therefore, the Project would not impact these species. Although the Golden Eagle is not a federally listed species under the Endangered Species Act, it has federal protection under the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act. Golden Eagles are found throughout the continuous U .S. and Alaska, and occupy a very wide range of habitat. For nesting , they most frequently use cliffs but will also nest in trees. There is some limited breeding in northeast Colorado, and Golden Eagles have been confirmed in the vicinity of the project. Pre-construction surveys would be conducted to identify any active nests and appropriate timing restrictions would be implemented to avoid impacts to the Golden Eagle. 71 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application In addition to federally listed species, state-listed species that could occur in or near the Project area include Mountain Plover, Western Burrowing Owl, Swift Fox, Plains Sharp-tailed Grouse, and Ferruginous Hawk. The project area is considered overall range for swift fox, which is a state-species of special concern . As with other terrestrial mammal species in the area, impacts to swift fox are expected to be minimal and primarily consist of temporary disturbance from construction activities. Swift fox could be temporarily displaced during construction of the substations and transmission line, but animals in the area are likely habituated to human activity due to the wind farm , and agricultural and oil and gas activities. The Mountain Plover is a state-species of special concern and occurs in the Project area. More than half of the world's population nests in the state, including in the Pawnee National Grasslands in Weld County. Mountain plovers inhabit prairie grasslands, arid plains and fields. Nesting areas include grasslands grazed by prairie dogs and cattle, and overgrazed tallgrass and fallow fields. Presence or absence surveys for Mountain Plovers will be conducted prior to construction in areas identified as suitable habitat. If any nests are found , appropriate construction timing limitations will be implanted to avoid impacts to the Mountain Plover. The Western Burrowing Owl is a state-threatened species and could occur in the Project area. In northeastern Colorado, burrowing owls are typically associated with prairie dog colonies. Burrowing owls can excavate their own burrows, but they usually depend on burrows that have been started by colonially burrowing mammals, especially ground squirrels and prairie dogs. A prairie dog colony was observed in one location along the proposed right- of-way during initial reconnaissance, and fall habitat assessments are expected to confirm these results. If suitable habitat for Western burrowing owl is encountered, spring surveys and mitigation measures will be implemented to avoid impacts to this species. The Plains Sharp-tailed Grouse is listed as endangered in Colorado. The bird formerly nested over much of the northern two-thirds of the eastern prairie, but the present population consists of only a few hundred birds in Douglas County (CPW 2010). CPW regularly conducts lek surveys in northeastern Colorado and has identified leks to the north of the Project area along the existing Cedar Creek - Keenesburg transmission line. If suitable habitat is identified during the fall habitat assessments, lek surveys will be conducted prior to construction and appropriate construction timing limitations will be implemented to avoid impacts to the Plains Sharp-tailed Grouse. The Ferruginous Hawk is a state-species of special concern in Colorado, and occurs year- round in the state. It is a common winter resident on the eastern plains in open grasslands and shrub steppe communities. Ferruginous Hawks nest in flat, rolling or rugged terrain in open areas, cliffs or rock outcrops, or isolated trees in grasslands. One historic Ferruginous Hawk nest has been identified within the proposed transmission line corridor by CPW. Fall 72 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application and spring surveys will determine the status of the nest and if necessary, construction timing will be implemented to avoid impacts to the nest. Unique Areas of Geologic, Historic, or Archaeological Importance Tri-State conducted a Class I archaeological database search of the Project area, as well as a Class III pedestrian survey. Four prehistoric artifact scatters were located along the proposed transmission line and are eligible for listing on the National Register of Historic Places (NRHP). These sites will be spanned and avoided by the Project. There are no areas of geologic importance in the vicinity of the project. Vested Water Rights The Project would have no impacts on vested water rights. Construction water and water to suppress dust during construction activities would be trucked into the site. 21-3-330.B.8—Long- Term Effects upon Physical and Socioeconomic Development The proposed Project would not have any adverse effects on physical or socioeconomic development of the area. 21-3-330.8.9—Mitigation of Adverse Impacts and Maximization of Positive Impacts Efforts would be made so the contour of the land and natural drainage patterns along the right-of-way are not disturbed . If land contours and drainage patterns are disturbed, efforts would be made to restore any negative effects. Because Weld County has a semi-arid climate, revegetation can be difficult. As a result, disturbances to land surrounding the construction area would be minimized. All practical efforts would be made to re-establish native vegetation in the disturbed area. Tri-State's Environmental Protection Measures for Construction Projects, included as Appendix B, addresses site reclamation of disturbed areas. Tri-State would continue to coordinate with CPW to develop appropriate mitigation measures that are compatible with Project goals and that would minimize impacts to wildlife along the transmission line and at the substations. 21-3-330.B. 10—Non-Structural Alternatives There are no non-structural alternatives that would accomplish the purpose and need for the transmission line and overall Project. If the Project is not constructed , Tri-State and its members would be required to seek other locations to construct adequate facilities to accomplish the Project goals. 73 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application 21-3-330.B. 11-Structural Alternatives Three transmission routing alternatives were considered in addition to the preferred alternative. These alternatives are discussed in more detail in the Alternatives to the Proposed Project section . 21-3-330.B. 12—Air and Water Pollution Impacts and Control Alternatives Air Pollution Impact and Control ,satisfies 21 -3-330.C.2 .d) Construction would last approximately seven to eight months. Construction activities associated with the proposed transmission line and substations would generate less than significant amounts of particulate matter from soil disturbances and diesel-powered equipment, and less than significant amounts of carbon monoxide and the precursor pollutants to ozone formation from tailpipe emissions. Any air pollutants generated would be widely dispersed across the Project area, short term in duration , and minimized by the small scale of construction operations for the substations, and excavating foundations and placing single pole transmission structures. Air pollutants also would be minimized through implementation of dust suppression and proper vehicle maintenance. Therefore, Project construction is not expected to contribute to the air quality status in the area. There would be no long-term air quality effects associated with routine operation and maintenance of the proposed transmission line and substations. Once construction activities have been completed , but before vegetation has been re-established, some minor amount of additional dust could occur. The generation of dust would be monitored by Tri-State, and the appropriate action would be taken to control the dust and ensure that potential wind erosion is minimized . Weld County is an attainment area for all measured pollutants, including particulate matter smaller than 10 micrometers in diameter (PM10). No air emissions would result from operation of the transmission line or substations. Water Pollution Impacts and Control There would be no direct impacts to water quality associated with regular operation or maintenance of the transmission line and substations. The Project would not create runoff in excess of historic levels and would not adversely affect drainage. There would be no alteration in the pattern or intensity of surface drainage as a result of construction or operation of the transmission line and substations. 21-3-330.B. 13—Design Alternatives: Access, Landscaping, and Architecture Access to the Project construction area would primarily be provided by existing roads and the 100-foot-wide right-of-way along the transmission line. Where construction of new roads is required to gain access to sites where the poles would be erected , Tri-State will design the roads to minimize impacts to resources while allowing access by construction and 74 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application maintenance vehicles. The access roads would not require architectural or landscape treatments. 21-3-330.8. 14—New or Upgraded Services New or upgraded services are not applicable to, and not required for, this Project. 21-3-330.B. 15—Hydrologic, Atmospheric, Geologic, Pedologic, Biotic, Visual, and Noise Impacts Biotic and atmospheric impacts are described above. Hydrologic Construction and maintenance of the transmission line and substations would not measurably impact surface water or groundwater quality. Additionally, there would be no long-term impacts to surface water or groundwater hydrology as a result of construction or operation of the Project. The preferred alternative crosses three named drainages. The drainages would likely be spanned by the transmission line and would not be impacted by the Project (Figure 7).The Project would not impact hydrologic flow of either surface water or groundwater, nor would it affect groundwater recharge. Minimal water would be used during Project construction . Water for construction purposes, including concrete foundations and dust control, would be brought in from off-site sources by a construction water provider. The source of the construction water would be from either a private well owned by the construction water company or from a municipality. No existing water rights would be impacted , and there would be no long-term use of water. If water is needed for revegetation around transmission structures or temporary access roads, the construction water provider would supply the water. No water would be required for the operation of the transmission line or substations. Geologic Construction and operation of the electric transmission line and substations would not alter the geology of the Project area. The topography of the Project area is relatively flat; slopes generally range from 0 to 9 percent across the area. Pedologic Appendix C includes a complete list of the soil map units that occur in the Study Area. Figure 8 shows the linear extensibility, or soil shrink/swell potential , in the Study Area. Shrink/swell potential of a soil is based on the change in length of an unconfined clod as moisture content is decreased from a moist to a dry state. The classes of shrink/swell potential are shown in Table 11 . The majority of the soils in the Study Area have low shrink/swell potential. 75 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Table 11 : Soil Shrink/Swell Classes Class Value Low 0-3% Moderate 3-6% High 6-9% Very high > 9% Figure 9a shows the soil erodibility based on factor K within the Project area. The factor K is a measurement of the soil's susceptibility to sheet and rill erosion by water; it is calculated as a function of an average diameter of the soil particles. Factor K is one of six factors used in the Revised Universal Soil Loss Equation to predict annual rate of soil loss in tons per acre per year. Factor K values range from 0.02 to 0.69, with higher values indicating higher losses. For the purpose of this report, soil K factors would be classified based on Table 12. Table 12: Soil Erodibility Classes Class Factor K Value Low 0.05-0.2 Moderate 0.21-0.4 High > 0.4 According to the NRCS Soil Survey of the Northern Part of Weld County (Appendix C), the majority of the soils, including those found at the substations, are moderately erodible. Soil erodibility by wind is shown on Figure 9b. No soils that are highly erodible by wind will be impacted by the Project. There are no data sources available that evaluate subsidence hazard in the Study Area. However, there are no mines in the vicinity of the Study Area, which may increase the risk of soil subsidence. Numerous soil types along the transmission line are designated as Prime Farmlands or Farmlands of Statewide Importance. However, placement of the wood pole transmission line support structures would not preclude the use of farmland under the suspected transmission line. Approximately 58 acres of Farmland of Statewide Importance and 27 acres of Prime Farmland , if irrigated would be permanently removed from agricultural uses for the substations. However, only a small portion of that would be disturbed for the Project. The facilities proposed for the Keota substation occur primarily on soils that are not considered Prime Farmlands. Nearly all of the soils in the vicinity of the Redtail substation are considered Farmland of Statewide Importance and cannot be avoided. The Project would not adversely affect any of the soil types within the Study Area. Construction of the project would cause some localized soil compaction and increase the potential for soil erosion. Long-term effects associated with soil erosion and compaction would be minimized or negated though use of EPMs (Appendix B). 76 �� �� - - ' - \--'1 ( Y _. � t - r Tri- State Generation and �_TrrI >> ,±1-- .,. �" Transmission Association , Inc .

(Noise Abatement) and Article IX, Section 14-9-10 et seq . of the Weld County Code. Visual The Project is not expected to significantly affect the aesthetics of the area. There is extensive oil and gas development in the area, as well as the nearby wind farm. The Keota substation is located adjacent to the 230-kV line and another 345-kV transmission line, as well as an oil and gas facility. Given the existing disturbance in the area, visual aesthetics of the area would be minimally impacted. 21-3-330.8. 16-Surface and Subsurface Drainage Subsurface drainage would not be impacted by the proposed transmission line or substations. The preferred alternative transmission line route would cross three named- drainages, Wild Horse Creek, Igo Creek, and North Pawnee Creek. The drainages would likely be spanned by the transmission line so there would be no direct impacts to water quality associated with regular operation or maintenance of the transmission line or substations. Project construction would not create runoff in excess of previous site levels and would not adversely affect drainage. There would be no alteration in the pattern or intensity of surface drainage as a result of construction or operation of the Project. A range of measures ensuring the Project does not impact water quality is listed in Appendix B; prior to construction , a Storm Water Permit for Construction Activities would be acquired from the Colorado Department of Public Health and Environment (CDPHE), if needed. 83 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application REFERENCES APLIC (Avian Power Line Interaction Committee (APLIC). 2006.

HEADQUARTERS: P.O. BOX 33695 DENVER, COLORADO 80233-0695 303-452-6111 POSITION STATEMENT Electric and Magnetic Field (EMF) Health Effects Lights, appliances, computers, power lines and any other devices that carry or use electricity produce electric and magnetic fields (EMF). The Earth itself also creates natural EMF in varying amounts. Therefore, we are all continuously exposed to EMF as a result of living in a society that so heavily relies on the use of electricity as a source of energy. In recent years, concerns have been raised that exposure to EMF might cause or contribute to adverse health effects, including cancer. We at Tri-State Generation and Transmission Association are aware of these concerns and we wish to express our position on EMF and our commitment to this matter. Scientists agree that the answers to these concerns must come from well-conducted research studies. During the last three decades several thousand studies aimed at a better understanding of this issue have been conducted around the world. The consensus of scientists familiar with these studies is that no significant risk to humans from long-term exposure to EMF has been established. In addressing this issue, Congress in 1991 asked the National Academy of Sciences to review the research literature on the effects from exposure to EMF and for the National Institute of Environmental Health Sciences (NIEHS)to conduct a scientific research program to evaluate the health risk to humans of EMF. The National Academy of Sciences formed the Committee to Review the Research Activities Completed Under the Energy Policy Act of 1992. The Committee issued their report in 1999 titled "Research on Power-Frequency Fields Completed Under the Energy Policy Act of 1992." In the report they state " the committee recommends that no further special research program focused on possible health effects of power-frequency magnetic fields be funded." The NIEHS in May 1999 prepared their report to Congress on the results of their sponsored research and other research conducted to date around the world. In a letter accompanying this report, the NIEHS Director concluded, "the scientific evidence suggesting that ELF-EMF exposures pose any health risk is weak". He goes on to say "virtually all of the laboratory evidence in animals and humans and most of the mechanistic work done in cells fail to support a causal relationship between exposure to ELF-EMF at environmental levels and changes in biological function or disease status." While these scientific reviews were conducted some time ago and EMF research has continued since then, the overall conclusions of these newer studies remain about the same as before. Tri-State recognizes its responsibility to provide wholesale electric service at the lowest possible cost in a manner that is safe, reliable and environmentally sound. This responsibility includes carefully designing and locating our facilities in strict accordance with the National Electric Safety Code and all applicable federal, state and local regulations. Despite the lack of clear evidence from reliable studies of any adverse effect EMF may have on human health, we will continue to construct and operate our facilities in a manner that minimizes, to the extent prudent and practical, the amount of EMF that is created. Since there are still unanswered questions and opposing theories, Tri-State agrees that limited research should continue in a credible and objective manner even though the federal government has ceased funding all such research studies. Accordingly, we will continue to be a sponsor of the EMF research program of the Electric Power Research Institute, of which we are a member. We will continue to closely monitor the results of these and other scientific studies as they are completed. Our commitment is to keep our member systems, our employees and our electric consumers informed of the results of this research and promptly and knowledgeably respond to all inquiries with accurate and current information. 9/11 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application Appendix B: Environmental Protection Measures for Construction Projects Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application TOPIC No. STANDARD ENVIRONMENTAL PROTECTION MEASURES General G-1 The contractor shall comply with all federal, state, and local environmental laws, orders, and regulations.

B-3 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application TOPIC No. STANDARD ENVIRONMENTAL PROTECTION MEASURES Noxious Weeds NW-1 To minimize introduction of noxious weed seed sources to the project area,the following measures will be performed.All heavy equipment utilized during construction will be washed prior to departure from the equipment storage facility. Washing of equipment prior to transport from one work site to another is not recommended, as on-site washing of equipment increases the chance of weed seed dispersal by drainage of water off of the site, across an area greater than the size of the work site. Equipment will have accumulations of mud`knocked off instead.This method promotes containment of weed seeds on the work site.All seed mixes and mulch used for reclamation activities will be certified weed-free. Soils and Geology S-1 The contractor shall mitigate soils compacted by movement of construction vehicles and equipment by 1)loosened and leveled harrowing or disking to approximate pre- construction contours and 2)reseeding with certified weed-free grasses and mulched (except in cultivated fields).The specific seed mix(s)and rate(s)of application will be determined by Tri-State. S-2 Movement of construction vehicles and equipment shall be limited to the right-of-way and approved access routes. S-3 Excavated material not used in the backfilling of poles shall be spread around each pole, evenly spread on the access routes in the immediate vicinity of the pole structure, or transported off site to a Tri-State-approved disposal location. Disturbed areas shall then be regraded to approximate pre-construction contours and reseeded as specified in S-1. S-4 Topsoil will be removed, stockpiled,and re-spread at temporarily disturbed areas not needed for maintenance access. Traffic T-1 The contractor shall make all necessary provisions for conformance with federal, state, and local traffic safety standards and shall conduct construction operations so as to offer the least possible obstruction and inconvenience to public traffic. Water Quality and Erosion WQ-1 Construction activities shall be performed by methods that prevent entrance or accidental spillage of solid matter, contaminants debris, and other objectionable pollutants and wastes into flowing streams or dry water courses, lakes,and underground water sources. Such pollutants and wastes include, but are not restricted to, refuse, garbage, cement, concrete, sanitary waste, industrial waste, radioactive substances, oil and other petroleum products, aggregate processing tailings, mineral salts,and thermal pollution. WQ-2 Dewatering work for structure foundations or earthwork operations adjacent to, or encroaching on, streams or water courses shall not be performed without prior approval by Tri-State and appropriate state agencies. Water and eroded materials will be prevented from entering the streams or watercourses by constructing intercepting ditches, bypass channels, barriers, settling ponds,or other approved methods. WQ-3 Borrow pits shall be so excavated that water will not collect and stand therein. Before being abandoned,the sides of borrow pits shall be brought to stable slopes, with slope intersections shaped to carry the natural contour of adjacent, undisturbed terrain into the pit or borrow area, giving a natural appearance.Waste piles shall be shaped to provide a natural appearance. WQ-4 Excavated material or other construction materials shall not be stockpiled or deposited near or on stream banks, lake shorelines, or other water course perimeters where they can be washed away by high water or storm runoff or can in any way encroach upon the water source itself. B-4 Keota-Redtail 115-kV Transmission Line Project Weld County USR and 1041 Application TOPIC No. STANDARD ENVIRONMENTAL PROTECTION MEASURES WQ-5 Waste waters from construction operations shall not enter streams, water courses, or other surface waters without use of such turbidity control methods as settling ponds,gravel-filter entrapment dikes, approved flocculating processes that are not harmful to fish, recirculation systems for washing of aggregates,or other approved methods.Any such waste waters discharged into surface waters shall be essentially free of settleable material. Settleable material is defined as that material that will settle from the water by gravity during a 1-hour quiescent period. WQ-6 A Storm Water Management Plan shall be developed, if required,to address all construction and reconstruction activities.The plan shall conform with all U.S. Environmental Protection Agency and Best Management Practices requirements.

Explain, in detail, the proposed use of the property. The proposed use of the property is described in the following sections of the Weld County 1041 Permit Application: Project Description, Introduction, Purpose and Need, and Proposed Action Sections. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. The Weld County Code, Chapter 22, Comprehensive Plan, has been reviewed and the proposed substations and transmission line is consistent with the intent of the Comprehensive Plan, including Land Use, Environmental Resources, and Natural Resources. The proposed transmission line and substations are located in an area that is located in the Agriculture Zone. Although the transmission line is not an agricultural use, it is a land use that is commonly located in agricultural areas and does not conflict with the goals outlined in the Comprehensive Plan. Careful site planning can be developed with only a localized loss of agricultural land quality. Ground disturbance for the transmission line is generally limited to the area immediately around the base of each pole. The substations would remove a limited amount of land from agricultural use, and agricultural practices could continue on adjacent lands. Impacts to environmental resources such as air, water, waste, noise, and public health would be minimal and limited to the construction period (see Sections 21-3-330.B.5.g, 21-3-330.B.12, and 21-3-330.6.15). Mitigation practices described in Appendix B of this Weld County 1041 Application would be implemented to minimize impacts to environmental resources. Natural resources such as sensitive wildlife areas, recreation areas, and mineral and energy resources would not be impacted by the proposed Project. Efforts would be made to avoid all sensitive wildlife areas; impacts to and proposed mitigation for sensitive wildlife areas are described in the Wildlife and Critical Wildlife Habitat section and Appendix B of this Weld County 1041 Application. No parks, open space or recreation areas are located near the Project. A number of oil and gas wells and facilities occur in the vicinity of the proposed transmission line and substations. Detailed design of the transmission line will ensure that poles are located to avoid any impact on these facilities. Appendix D—USR Questionnaire 1 Keota—Redtail 115-kV Transmission Line Project Weld County USR and 1041 Permit Application 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the zone district in which it is located. The proposed Project is located within the Agricultural Zone District. Major facilities of public utilities may be constructed, operated, and maintained in the Agricultural Zone District upon approval of a permit in accordance with the requirements and procedures set forth in Article II, Division 4 of Chapter 23 of the Weld County Code. Major facilities of a public utility are also subject to the provisions of section 23-4-420. This section of the code states that the applicant shall have the burden of proof to demonstrate that there is a need for the facility within the proposed area of service; this is discussed in the Purpose and Need section of this Weld County 1041 Application. 4. What types of uses surround the site (explain how the proposed use is consistent and compatible with surrounding land uses). Land to the north, south east, and west of the Project area is part of unincorporated Weld County and is zoned agricultural. The parcels over which the line will cross include irrigated and dry land farm ground, pasture land, and oil and gas development. There are no houses located within 0.5 mile of the transmission line. There are multiple oil and gas wells and facilities, and existing 230-kV and 345-kV transmission lines in the area as well. 5. Describe in detail, the following: a. Number of people who will use the site No people would use this site, other than those performing routine maintenance and monitoring of the transmission line and substations. b. Number of employees proposed to be employed at this site Construction crews could have up to 30 people during construction. The Project would generate infrequent trips to the transmission line and substations during operations with the line being inspected annually and for occasional maintenance. See Section 21-3-330.B.7 of the Weld County 1041 Application for additional information. c. Hours of operation Not applicable. d. Type and number of structures to be erected (built) on this site The new transmission line would be single circuit, 115-kV line constructed on primarily wooden H-frame structures within a 100 ft right-of-way. The transmission 2 Appendix D—USR Questionnaire Keota—Redtail 115-kV Transmission Line Project Weld County USR and 1041 Permit Application line would consist of approximately 124-198 structures, with three conductors, and an optical ground wire for internal Tri-State communications. Total length of the transmission line is approximately 24.7 miles. e. Type and number of animals, if any, to be on this site No animals would be on this site in association with the transmission line. f. Kind of vehicles (type, size,weight) of vehicles that will access this site and how often Construction equipment and duration of construction is found in Table 8 in Section 21-3-330.6.7 of the Weld County 1041 Application. g. Who will provide fire protection to the site The proposed Project is located in the Pawnee Fire Protection District. All applicable fire laws and regulations, as outlined in the Colorado Revised Statutes (CRS) 31-16- 601, would be observed during the construction period. Tri-State would advise construction personnel of their responsibilities under the applicable fire laws and regulations, including taking practical measures to report and suppress fires. h. Water source on the property(both domestic and irrigation) Potable water for construction crews would be provided by a potable water supplier. A constant domestic water supply will not be supplied for the site. Minimal quantities of water for construction dust suppression would be brought in by a water truck on an as-needed basis. There will be no permanent water supply at the proposed Project site. i. Sewage disposal system on the property (existing and proposed) Sanitary portable toilets with a regular cleaning service would be provided for the construction crew. There are no plans for a permanent sewage disposal system associated with the proposed Project. j. If storage or warehousing is proposed, what type of items will be stored There would be temporary storage of construction materials at the proposed Project site. Construction, operation, and maintenance activities would comply with all applicable federal, state, and local laws and regulations regarding the use of hazardous substances. The only hazardous chemicals anticipated to be used on site are those found in diesel fuel, gasoline, coolant(ethylene glycol), and lubricants in machinery. Hazardous materials would not be drained onto the ground or into streams or drainage areas. In its contract with the construction contractor, Tri-State Appendix D—USR Questionnaire 3 Keota—Redtail 115-kV Transmission Line Project Weld County USR and 1041 Permit Application will specify that it will hold a required pre-construction meeting with the contractor to ensure that all applicable laws and Tri-State's procedures will be followed. Tri-State's Project Environmental Protection Measures for Construction Projects are attached as Appendix B of the Weld County 1041 Application. Enclosed containment would be provided for all trash. All construction waste, including trash and litter, garbage, other solid waste, petroleum products, and other potentially hazardous materials would be removed to a disposal facility authorized to accept such materials. 6. Explain the proposed landscaping for the site. The landscaping shall be separately submitted as a landscape plan map as part of the application submittal. No landscaping would be performed in association with construction of the transmission line or substations. 7. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Tri-State will exercise care to preserve the natural landscape and will conduct its construction operations so as to prevent any unnecessary destruction, scarring, or defacing of the natural surroundings in the vicinity of the work. Mitigation practices described in Appendix B of the Weld County 1041 Application shall be implemented to minimize impacts to environmental resources. Except where clearing is required for permanent works or excavation operations, all trees, native shrubbery, and vegetation shall be preserved and protected from damage by the construction operations and equipment. On completion of the work, all work areas except existing access roads and substation sites would be revegetated as soon as practical using a landowner approved seed mixture. Alternatively, in areas where mutually agreed to by Tri-State and landowner, the ground shall be scarified or left in a condition that would facilitate natural revegetation, provide for proper drainage, and prevent erosion. Site-specific revegetation measures would be developed after consultation with the landowner or land manager. All destruction, scarring, damage, or defacing of the landscape resulting from the contractor's operations shall be repaired by the contractor. 8. Explain how the stormwater drainage will be handled at the site. A drainage report is not being required as part of the application materials. The project would not create runoff in excess of previous levels and would not adversely affect drainage. There would be no alteration in the pattern or intensity of surface drainage as a result of construction and operation of the transmission line. Drainage from the Keota substation would be directed towards a proposed detention pond located to the southeast 4 Appendix D—USR Questionnaire Keota—Redtail 115-kV Transmission Line Project Weld County USR and 1041 Permit Application of the facilities on the substation property. Drainage from the Redtail substation would also be directed towards a proposed pond located on the east side of the property. The ponds at both substations will drain to historic drainageways by way of proposed outlet structures. The outlet structures will release flows at a rate equal to the 5-year historic flowrate. 9. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. Construction would begin in June, 2014 and be completed in late January/early February 2015. Reseeding would be completed as soon as practicable after construction. 10. Explain where storage and/or stockpile of wastes will occur on this site. Materials would be temporarily stored on the Keota substation property during construction, but there would be no stockpile of wastes on site. Dumpsters would be provided for construction waste and would be emptied on a regular or as-needed basis. There will be no permanent storage or waste stockpiles on site.

We will continue to review the impacts which such an outage may have on the operation of the Cedar Creek II project, and request that the County require Tri-State to obtain Cedar Creek Wind Energy, LLC and Cedar Creek II's approval of a plan for any such outage before Tri-State commences construction at the Keota substation site. Any such plan should address, at a minimum, the timing for any outage as well as the additional costs and revenue losses that will be experienced by Cedar Creek II in connection with the outage. 3. The plan for the proposed Keota substation also indicates that a portion of the existing Laramie River/Story Transmission Line will be relocated to cross the Cedar Creek Keenesburg Transmission Line in a different location. We would request that the County's approval of Tri-State's USR include a condition that prior to the start of construction they execute a crossing agreement with Cedar Creek Wind Energy, LLC that will allow for the placement of the relocated transmission line at this new location. 4. Finally, we understand that the County has required Tri-State to process subdivision exemption RECX13-0117 in order to create the 20 acre parcel on which the Redtail substation will be located. We would request that this exemption not be recorded until the County finally approves Tri-State's USR13-0054 and Cedar Creek II has consented to the partial vacation of its USR 1723, so Cedar Creek II can confirm that the newly created parcel and Tri-State's proposed facilities as approved by USR13-0054 will not adversely affect the Cedar Creek II Wind project. Thank you for the opportunity to review these materials and the additional information that you have been able to provide us as we review Tri-State's proposal.

("Tri-State"). We very much appreciate your assistance to date in providing us with information regarding Tri-State's proposal, and will continue to monitor the proceedings to ensure that Tri-State's proposed project • will not have any negative effects on our existing Cedar Creek II Wind project. Based on our current understanding of the Tri-State proposal, we have several comments with regard to their application: 1. We understand that an approximately 20 acre portion of Tri-State's proposed Use by Special Review Permit on property owned by Nelson Ranches, Inc. overlaps a portion of the Use by Special Review Permit 1723 that was granted by Weld County for the Cedar Creek II Wind Project. According to Tri-State's application,this 20 acre site will be used to develop the proposed Redtail substation. Under the County's policies,we understand it will be necessary for the County to vacate that portion of the Cedar Creek II Use by Special Review permit that covers such 20 acre parcel. Cedar Creek II has reviewed the Tri-State application and does not believe that the partial vacation of the Cedar Creek II USR with respect to this 20 acre parcel within the Nelson Ranches property will invalidate or otherwise have any negative effect on the Cedar Creek II project. However, we reserve the right to continue our review of the proceedings related to Tri-State's application to ensure that this continues to be the case as the project proceeds through the public hearing process. We request that if the County approves the Tri-State application, that they include a condition which would require Cedar Creek II's consent to the partial vacation of the Cedar Creek II Use by Special Review Permit prior to recordation of Tri-State's Use by Special Review map. 2. We also understand that certain activities associated with the construction of the proposed Keota substation as described in the Tri-State application will require an outage Holland&Hart UP Phone[303]295-8000 Fax[303]295-8261 www.hollandhart.com 555 17th Street Suite 3200 Denver,CO 80202 Mailing Address P.O.Box 8749 Denver,CO 80201-8749 Aspen Boulder Carson City Colorado Springs Denver Denver Tech Center Billings Boise Cheyenne Jackson Hole Las Vegas Reno Salt Lake City Santa Fe Washington.D.C.

(Tri-State)is submitting this letter to amend the application submitted on November 25,2013 for the Use by Special Review(USR)and 1041 Permit Application for the Keota-Redtail 115-kV Transmission Line Project located in parts of Township 9 North,Range 61 West; Township 9 North,Range 60 West; Township 9 North,Range 59 West;Township 10 North, Range 59 West; and Township 10 North,Range 58 West,Weld County. Tri-State is proposing the addition of another circuit to the proposed single-circuit 115-kV line. As the County is aware,there is vast development potential for oil and gas in this region. This development is very dynamic and changing sometimes on a daily basis. At this time,several different companies are in the midst of exploration and have indicated sizeable potential electric loads in the area beyond what is currently being considered. The proposed single-circuit 115-kV line would not be adequate to support all of this potential development. Since these loads are so dynamic and have not been firmed up completely as of this date, Tri-State believes it is in everyone's best interest to have the flexibility in the USR and 1041 application to allow for implementation of a double-circuit. This would position Tri-State to be able to better serve additional electrical loads in the area and would allow Tri- State to respond to large development more quickly. It would also provide for future reliability needs and operational flexibility under transmission contingencies, increasing the reliability to the loads in the area. In addition to the changes to the Purpose and Need described above,the alterations related to a double- circuit would include: • Self-weathering, steel pole construction,rather than wooden H-frame(see attached Figure 3a). Figure 3 in the original application included a typical wood H-frame structure. • Disturbance from the project would be reduced from 103 acres to 100.5 acres, due to the smaller footprint for the steel poles. • Foundation setting would take approximately 16 weeks (compared to 1-2 weeks presented in Table 8 in the original application) • Changes to some of the transmission line characteristics,shown below in comparison to Table 2 in the original application.

Your proposed route is not good. Noel Pace Colorado Cattlemen's Agricultural Land Trust August 26, 2013 H. Steven Gray Tri-State Generation and Transmission Association, Inc. 1100 W. 116th Ave. Westminster, CO 80234 Sent via Email to: sgray@tristategt.org RE: Proposed Keota-Redtail 115kV Electric Transmission Line and CCALT Held Conservation Easements Thank you for contacting the Colorado Cattlemen's Agricultural Land Trust (CCALT) in regards to Tri-State Generation and Transmission Association, Inc. 's (Tri-State's) plans to install the proposed Keota-Redtail 115kV Electric Transmission Line across Weld County, Colorado. It is CCALT's understanding that you will be seeking to acquire a new right-of-way to either parallel the existing line or diverge slightly from the existing line to connect the Keota- Redtail stations. Attachment 1 to this letter shows the three proposed routes you sent us. Attachment 2 shows CCALT's Conservation Easements in this area. Please keep this map confidential and use it only for the purposes of siting this transmission line. Attachment 3 shows the specifics of the conservation easements which your proposal would affect. CCALT values our partnerships with our landowners and wants to ensure our landowners are comfortable with the information presented to Tri-State regarding their conserved property. For that purpose, our affected landowners have been copied on this letter. Conservation easements do not allow public utilities to cross them. It is a lot easier on everyone to try to avoid conserved property in the first place. We urge you to reconsider your alignment of the powerline to avoid any and all conservation easements CCALT or any other conservation organization may have in the area. Though one of your proposed routes follow an existing line, the existing line was put in place before many of the conservation easements existed. In addition, the line through Lonesome Pines is not a permanent right-of-way and is subject to an expiration date. From the attached map, it looks as if Tri-State could route their proposed line east of Everitt, take a southerly route to avoid Lonesome Pines, and reconnect to the existing line and miss Ehmke to the north. CCALT and the Ehmke's did work with Beyond Petroleum (BP) in 2009 to install part of the existing line shown on your map. However, where the line crossed conserved lands, no powerpoles were placed. The right of way is only for an overhead wire. BP also paid CCALT and the Ehmke's all costs described later in this letter. If it can be shown that CCALT's conservation easements cannot be avoided, any powerline right-of-way through conserved properties must be condemned. If the Tri-State makes the decision that it cannot re-route the proposed powerline and that it will pursue condemnation of a right-of-way through conserved lands, CCALT can settle in lieu of condemnation if certain requirements are met. These requirements are outlined below. 1 . If you would like to proceed with the route through CCALT's conserved properties, an upfront $ 1 ,000 review fee per affected property is required to allow CCALT staff to work on this issue. As we are a nonprofit, it is standard for us to ask third parties for review fees up front when they are requesting interpretations of our easements and polices. Once we receive this, CCALT can initiate our review of the proposal, which could include a site visit as well as discussions with the Board of Directors of CCALT as well as the affected landowners. 2. CCALT's next step would then be to work with the landowners and utility to come up with the least impactful alternative for siting the powerline across those portions of the conserved properties the powerline must cross. 3. The appraisal for the right-of-way must cover at least the full fair market value for the portion of the properties being condemned (not the land's value as encumbered by a conservation easement). This is because the easement value has not been extinguished and CCALT holds that value in the public's trust. The full fair market value of the right-of-way will then accordingly be split according to the termination proceeds listed out in the various conservation easements between CCALT and the landowner. 4. Tri-State must also offset the damages done to the properties' conservation values, which are not quantified in the real estate appraisal. This cost includes damages to the shortgrass prairie or other specific ecosystem types. CCALT has to make sure that the damages done to the properties' conservation values are offset enough to create at least a net neutral outcome. Usually, the monetary value of the damages is invested back into a restoration project on the affected property itself, to offset the damage. The type of restoration project is developed between CCALT, the landowners and the utility company. If that is not feasible, we will ask that the money be spent to do more conservation work in Colorado's shortgrass prairie landscape. 5. CCALT will ask that the utility to pay all of CCALT staff and legal costs associated with this proposed pipeline, which we will diligently document. 6. CCALT will reserve the right to review the proposed right-of-way agreement to be sure standard language is included regarding restoration of the right-of-way and weed control. We must also be included as a signatory on the agreement, as we hold a real property interest. In the end, if you can reroute to avoid conservation easement conserved property, it will be the least costly for all of us. We look forward to speaking with you regarding your plans.
