SUMMARY: CO ect POWER Engineers Mike Doyle Charles Hutchinson Amanda O'Connor Cindy Smith Tad Stout Cindy Smith, POWER Engineers, welcomed the Community Working Group (CWG) members and gave a brief overview of the siting and routing process that Xcel Energy is utilizing to identify the most appropriate route for the proposed transmission lines and new Eaton -area substation (slide 3). Xcel Energy and their contractor, POWER Engineers, Inc., have collected environmental resource and land use data for the study area and conducted an opportunities and constraints analysis to identify preliminary alternative route segments, which will be presented today. Cindy provided a summary of the results of the first public open house (held November 13, 2019, in Eaton, Colorado) and comments received from the community (slides 4 and 5). Of the issues identified in the comments, three topics were included in many comments that Xcel Energy believed prudent to address with the CWG—undergrounding the transmission line, potential health effects of electric and magnetic fields, and the project construction process. Regarding undergrounding the transmission line, Mike Doyle, POWER Engineers, stated that undergrounding is technically possible but has multiple technical challenges (slide 7). Undergrounding is typically used in urban areas and for very short distances. An undergrounded transmission line must be PAGE I OF 4 MEETING MINUTES routed through a concrete duct bank and vault system. As a result, the associated impacts of construction on land use in the transmission line easement is much greater than an overhead transmission line (e.g., greater surface disturbance, longer construction periods). Also, underground transmission lines have substantially higher installation, maintenance, emergency material, and repair costs. The time to complete repairs also is much greater for an underground line and outages can last much longer. For these reasons, undergrounding is not a technically reasonable option for this Project. Dr. Pam Dopart, Ph.D., CIH, Exponent, addressed the potential health effects of EMF. Pam is a health scientist. Her background is in understanding of exposures people are exposed to in workplaces and the effects on health. Pam said EMF is produced wherever electricity is generated, transmitted, or used. In modern society, we are surrounded by EMF in our daily lives; common sources include appliances, electrical wiring, nearby distribution and transmission systems, electronics, office equipment, and power tools. Pam said that various research projects indicate that EMF intensity falls off quickly with distance from the source. While there are no national or state standards in the U.S. for limiting EMF based on health effects, the Colorado Public Utilities Commission (CPUC) considers magnetic field levels of 150 milligauss (mG) at the edge of a right-of-way `reasonable' (she stressed that this is not a health based limit). Two international scientific organizations have developed exposure limits to protect health and safety (based on evaluation of relevant health research). The International Committee on Electromagnetic Safety (ICES) recommends general exposure values of 9,040 mG for magnetic fields and 5 kilovolt per meter (kV/m) for electric fields. The International Commission on Non -Ionizing Radiation Protection (ICNIRP) recommends general exposure values of 2,000 mG for magnetic fields and 4.2 kV/m for electric fields. Pam continued that, over the past 40 years, the large body of scientific research on electric power EMF has been reviewed by many leading public health agencies, including the U.S. National Cancer Institute (NCI) and the World Health Organization (WHO). None of these authorities have concluded that power frequency EMF have been shown to cause or contribute to cancer or other adverse health effects in adults or children. The WHO's information for the public on its EMF website states that "despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health." Further, she said, a substantial amount of research has been conducted on the possible effects of EMF on the health, behavior and productivity of domestic animals, including livestock and wildlife. The research to date does not suggest that electric fields or magnetic fields (or any other aspect of high -voltage transmission lines, such as audible noise) result in adverse effects on the health, behavior, or productivity of fauna, including dairy cows, sheep, pigs, and a variety of other species (e.g., small mammals, deer, elk, birds, and bees). Also, no adverse effects on crops and plants have been reported either at field levels typically found under transmission lines. Links to information on the WHO and NCI websites are located here: https://www.who.int/ and https://www.cancer.gov/. Carly Rowe, Xcel Energy, stated that Xcel Energy was required to model EMF associated with the transmission lines as part of their Certificate of Public Necessity (CPCN) filing with the CPUC, and that information is available to the public here. Scott Randel asked if, in general, EMF levels right under transmission lines meet the CPUC standard. Xcel responded, yes, the EMF fields meet the CPUC standards in the right-of-way. Andy Nagel asked if EMF would interfere with GPS signals. Pam said the EMF from transmission lines operates from 50 to 60 megahertz (MHz), whereas GPS signals operate at MGz in the thousands. The transmission line fields are at a much lower than the level that would cause GPS interference. Mike Doyle asked Pam about pacemakers stating that comments were received from the public on this issue. Pam said EMF levels from transmission lines do not interfere with pacemakers because the EMF levels fall rapidly with distance from a transmission line. Also, EMF is readily blocked by objects and modem pacemakers include a coating to block interface of with most kinds of electric waves (MRI machines are an example where there could be an issue with pacemakers). Pam said studies on the effects of EMF on pacemaker indicate there is not an effect on pacemakers in everyday life. Scott Randle asked about audible noise levels from the transmission line. Mike said a noise study also is included in the CPUC CPCN filing and it shows standard noise levels for this type of line PAGE 2 OF 4 MEETING MINUTES Mike then played an animation video that provides an overview of the project and the construction process that was developed for the public open house scheduled for January 28, 2020. The video is available on the project website(https://xcelenergynortherncoloradoareaplan.com/). Becky Weideman asked about the maximum height of agricultural equipment that can work underneath a transmission line. Luke Birkholtz, Xcel Energy, said the industry standard is from 14 to 17 feet where equipment can move safely under the transmission line. Luke will bring a copy of the standards to the next CWG meeting for reference. Arlen Anderson asked about compatibility with pivot irrigation; specifically, if a pivot is located at the edge of a field where the transmission line is placed. Mike said the pivot laterals can pass underneath the transmission line between transmission structures. Luke Birkholz add that Xcel Energy will plan for pivot irrigation with tower spotting and working with individual landowners on the route selected for construction. Mike turned the discussion to the siting study process for identifying a substation target area. Mike discussed the best management practices for siting a substation (slide 13) and reviewed the process for identifying a target area for the substation ((slides 14-20). Once the target area was identified, a representative set (14) of conceptual substation locations were selected (slide 18). For each conceptual location, Xcel conducted created a load flow model of the Eaton area electrical system based on 2019 peak loading; generated voltage 'heat maps' that highlight where voltage is unacceptable; and estimated the cost of distribution work based on line miles of feeder rebuild, and the level of voltage support required. Mike showed examples of voltage studies for four conceptual locations to provide the CWG with examples (slide 19). (The voltage studies conducted for all 14 conceptual locations were provided to CWG members as a handout). The substation target area was re-evaluated against the results of voltage studies and was modified accordingly. Xcel Energy is currently reaching out to approximately a dozen property owners to assess whether they are open to locating the substation on their land. Mike shared the facility siting criteria that was revised based on feedback provided by CWG members after the first CWG meeting (slide 21). Mike reviewed the results of the resource inventory and sensitive mapping (slide 23). Resource inventory and sensitivity mapping were created for existing land use, planned land use, oil and gas, biological resources, cultural resources, and visual resources. The sensitivity mapping was generated using the facility siting criteria reviewed at the last meeting. Then, a composite sensitivity map was created that allowed Xcel Energy/POWER to identify opportunities for the transmission lines. Preliminary route segments were placed where opportunities exist (slide 24). (The mapping was provided to the CWG members as handouts.) Arlen Anderson and Paul Hungenberg said multiple pipelines present in the study area are not displayed on mapping. The pipeline data was obtained for the state of Colorado. Carly said Xcel Energy/POWER may need to contact pipeline companies and Weld County for additional data. Arlen asked if transmission lines are ever placed over a residence. Mike responded that residences are noted as highly sensitive in the facility siting criteria so would not constitute a siting opportunity. The transmission line route will be placed where no existing houses are in the right-of-way. Mike said about 75 total preliminary route links (segments) were identified, adding up to approximately 125 miles of route studied for an approximately 22 -mile -long transmission project. Some of these routes will be carried forward and some will drop out based on input from the CWG members and the public, he said. Two link segments along the railroad posed engineering difficulty due to physical space limitations for a right-of- way and will likely be dropped. Mike asked the CWG members to review the route links and provide feedback to Xcel Energy between now and the public open house scheduled for Jan 28, 2020, or shortly thereafter. The preliminary route links will be presented at public open house. Becky Weideman asked why in some cases a route link might follow a road for some way then veer of the road right-of-way. Mike responded it could be due to a cluster of residences along the road that warranted adjusting the route link to a half section line. Paul asked how a route can be identified before a substation location is determined. Mike said an alternative route cannot be locked down until a substation location is PAGE 3 OF 4 MEETING MINUTES determined but that Xcel plans to have a range of alternative substation locations within two to three weeks if possible Mike provided an overview of the process for comparing and ranking route links to allow full potential alternative routes to emerge (slides 25 and 26) as the next step in the process The results of the comparison and ranking process will be shared at the next CWG meeting, he said The next CWG meeting is scheduled for February 27, 2020, from 11 a m to 1 p m at the Eaton Area Community Center In closing, Mike encouraged the CWG members to attend the public open house on January 28, 2020, from 2 to 7 30 p m at the Eaton Area Community Center, and to spread word of the meeting to their friends and neighbors Rita Ruderman, POWER Engineers, mentioned there will be three computer stations at the public open house set up so that individuals can provide geolocated comments on the preliminary route segments The meeting adjourned at 1 15 pm PAGE 4 OF 4 NORTHERN COLORADO AREA PLAN PROJECT COMMUNITY WORKING GROUP MEETING 2 AGENDA PURPOSE Discuss community comments received to date, review resource inventory and sensitivity analysis results, review preliminary route alternative segments DATE AND TIME January 16, 2020, 11 00 a m -1 30 p m ATTENDANCE CWG members, Xcel Energy, POWER Engineers LOCATION Eaton Area Community Center, 1675 3rd Street, Eaton, Colorado HANDOUTS Agenda, presentation slides and maps AGENDA 11 00 -11 03 Welcome and Lunch 11 03 -11 10 Review Results of Open House #1 and Community Comments 11 10 - 11 45 Special Topics • Undergrounding • EMF and Health • Construction Process Video Xcel Energy Xcel/POWER Engineers POWER Engineers 11 45— 1200 Substation Target Area Xcel/POWER Engineers • Study Process and Results 12 00 -12 10 Break (working lunch) 12 10- 12 20 Siting Criteria Review POWER Engineers 12 20- 12 40 Resource Inventory Data and Opportunity/Constraints Results POWER Engineers 12 40 - 115 Preliminary Route Alternative Segments (Links) POWER Engineers 1 15 —1 30 Action Items All • Next meeting o Establish date and time • Follow-up items 130 Adjourn Public Service Company of Colorado Northern Colorado Area Plan Ault to Cloverly Transmission Project This page intentionally left blank APPENDIX C v ORTHERN COLORADO IUUI.PI.I R EA PLAN AULT TO CLOVERLY - TRANSMISSION PRQJECT Ni P� • r Xcel Energ9T � �Y•�•^4 ; 'r.: , ,.f jJJ C"�'�I 'rrl�i•j,' i Xcel Energy Meeting Agenda •Review Results of Open House #1 and Community Comments •Special Topics •Undergrounding •Electric and magnetic fields and health •Construction process (video) •Substation Target Area •Break (working lunch) •Siting Criteria Review •Resource Inventory Data and Opportunity/Constraints Results •Preliminary Route Alternative Segments (Links) •Action Items Xcel Energy Siting and Routing Process We Are Here ALTERNATIVE SITES OPPORTUNITIES AND ALTERNATIVE SITES ANDROUTES DATACOLLECTION CONSTRAINTS SENSITIVITY ANDROUTES COMPARISON, RANKING, PERMITTING ANALYSIS IDENTIFICATION AND SELECTION identify StHy Opportunitln Composite Environmental and Engineering OpportunXits and Constraints Map • Summary Crnativ wnTahb • • WeW County • Etlating TrammiWpnLlnes Fl • mlix AM<rvdre Routes and 1041 Permit • Deslgmted/Proposed Utility Miu4��llawd • Identify Preliminary Route 5ulestaticn SltingArtn Other Permit.

Identification of environmental constraints will be based on an analysis of the sensitivity of each resource from the introduction of a transmission line or a substation site. Sensitivity is defined as the measure of probable adverse response of each resource to potential direct or indirect effects associated with construction, operation, and maintenance of a transmission line or a substation site. Criteria used to make determinations of environmental sensitivity include the following: • Resource Value: A measure of rarity, high intrinsic worth, singularity, or diversity of a resource within the area. • Protective Status: A measure of the formal concern expressed for a resource either through legal protection or by assignment of special status designation. • Present and Future Use: A measure of the level of conflict based on land -management policies and/or use and may include issues of specific concern to the agencies and public. Considering the criteria described above, the environmental data will be evaluated and assigned a sensitivity level of low, moderate, high, and exclusion as defined below. The lower the sensitivity of a resource, the more compatible it would be for siting a transmission line and substation in a given area. -: Areas where legal status (i.e., wilderness areas, jurisdictional policy [e.g., active airports]) would prohibit, or most likely prohibit, the location of transmission or substation facilities. Locations of exclusion areas are considered to be undesirable for location of a transmission line or substation. Northern Colorado Area Plan WAPA Ault - Cloverly Transmission Project Page 6 of 7 January 16, 2020 • High Sensitivity: Areas determined to be less suitable because of unique, highly valued, complex, historic, or protected resources and significant potential conflict with use, or areas posing substantial hazards to construction and operation of the transmission line and substations. Locations of high sensitivity are considered to be high constraint or least desirable for location of a transmission line or substation. • Moderate -High Sensitivity • Areas of potential environmental effects on important or valued resources, resources assigned special status, or some conflict with use. Locations of moderate sensitivity are considered to be moderate constraint areas and less desirable for siting a transmission line or substation. • Low -Moderate Sensitivity • Lim+nsitivity: Areas where resource conflicts identified through the feasibility study process are minimal. These areas of low sensitivity are considered to be of minimal constraint, or high opportunity, for locating a transmission line or substation, particularly in association with existing transmission line corridors. Opportunity Area Locations where there are opportunities for the introduction of a transmission line and/or a substation. Siting opportunities generally include areas of low sensitivity and locations in proximity to, or including, existing or planned linear facilities and corridors that have been disturbed previously or designated for future use as utility corridors or industrial use(s). Typically, such opportunities include existing transmission line (44 kV and greater), major transportation corridors (county roads and state highways), pipeline corridors, and railroads that potentially allow for parallel linear facilities.
