About this report
This is Otter Tail Power Company’s sixth biennial Stewardship Report. We selected its content based on the environmental, economic, community, and other standard disclosures outlined in the Global Reporting Initiative (GRI) Standards reporting guidelines released in 2016. We comply with the GRI Standards at the “core” level. The GRI guidelines provide a voluntary reporting framework used worldwide to communicate meaningful information about issues that impact reporting organizations and their stakeholders. As in our five previous biennial reports, our reporting boundaries include the business areas on which Otter Tail Power Company, and no other subsidiary of Otter Tail Corporation, has direct impact or significant influence. We’re reporting 2016 information throughout this report, unless we indicate otherwise due to data availability. At the end of the report you’ll find the GRI Index that shows what we reported relative to the guidelines. For questions about the report, contact Sarah Casey, Otter Tail Power Company Communications Specialist, at pr@otpco.com.
MATERIALITY ASSESSMENT
We conducted this materiality assessment to learn what stakeholders view as important in the areas of environmental, economic, and community stewardship and governance. This assessment helped us define the contents of our Stewardship Report published in 2017. We collected feedback in 2016. The assessment includes Otter Tail Power Company, a subsidiary of Otter Tail Corporation (NASDAQ:OTTR). This is our first materiality assessment, and we followed the guidance of the Global Reporting Initiative (GRI) Standards released in 2016.
Stakeholder feedback and engagement We included feedback from the following stakeholders: • Residential, commercial, and industrial customers. • Community Advisory Boards. • Employees. • Shareholders. • Regulators and regulatory agencies. • Legislators. • Stakeholders specifically interested in our Resource Plan, a strategic document that outlines the resources required to meet our customers’ needs for reliable service during the next 15 years. The boundary of our feedback and assessment, where our impact occurs as defined by GRI, encompasses the geography where we provide service in Minnesota, North Dakota, and South Dakota. 4

Feedback sources by stakeholder As a public electric utility, we’re required to engage with our stakeholders and solicit feedback. We also proactively reach out to our stakeholders to ensure they’re satisfied with our service, that our operations are safe and responsible, and that we deliver financial returns.
Residential, commercial, and industrial customers We collected feedback at open houses and public forums. And we reviewed complaints from our toll-free customer service phone line. We also used online and social media comments to solicit feedback. We have approximately 3,000 followers on our social media accounts and review comments on a regular basis.
We solicited feedback on specific projects. For our hydro-relicensing project, approximately 30 landowners and 7 other entities participated in an open house, including the Federal Energy Regulatory Commission and the Minnesota Department of Natural Resources. For our request to adjust rates in Minnesota, only one customer attended one of our four public forums and one customer commented in Speak-Up online. We surveyed our customers for customer satisfaction twice in 2016 using the independent vendor American Customer Satisfaction Index (ACSI). ACSI compared our satisfaction rating with those of the top electric or dual electric/gas investor-owned utilities. The organization surveyed 500 residential customers. Key metrics included customer expectations and perceptions about the value and quality of their experiences with our services, personnel, and website. ACSI also asked customers about experiences with power outages and restoration. We engaged Bellomy Research, Inc., to evaluate satisfaction with service provided by customer service representatives and field service technicians. Bellomy contacted 3,000 customers and delivered in-depth reports that help us respond to emerging issues that may require operational improvements.
Community Advisory Boards
These boards include community leaders from healthcare facilities, K–12 school systems, colleges, chambers of commerce, and businesses, as well as Otter Tail Power Company representatives from customer service, operations, sales, economic development, and public relations. They meet two to three times a year to discuss local topics of interest, including upcoming projects, economic development, and business partnerships.
Employees
We held several employee events to share information about our company’s performance and goals and encouraged employees to ask questions and voice concerns aloud or anonymously on paper. Events included, but were not limited to, Executive Forums, during which senior management reached all employees; Customer Care Conferences, during which customer service leadership reached almost all of our approximately 40 customer service representatives and administrative support staff; and Managers’ Meetings, during which subject matter experts reached almost all of our approximately 60 managers. Otter Tail Corporation, our parent organization, offers an anonymous ethics hotline for all employees.
Shareholders
Investors contacted the Investor Relations Department at Otter Tail Corporation, which also invites investors to the Annual Meeting of Shareholders. In 2016 Otter Tail Power Company’s revenues represented approximately 53 percent of Otter Tail Corporation’s consolidated operating revenues.
Regulators and regulatory agencies
We continued to work with regulatory agencies on the local, state, and federal levels. Through agency and public meetings, our unified efforts helped to implement procedures that were transparent and encouraged participation from interested parties.
Community Advisory Board meeting in Bemidji, Minnesota
Legislators
Otter Tail Power Company has a Legislative Affairs team that works in each of the states we serve. The team reaches out to elected officials to share information about topics and pending legislation related to electric power generation and delivery.
Stakeholders interested in our Resource Plan
Our 2017–2031 Resource Plan identifies the most cost-effective combination of resources for meeting our customers’ needs for reliable service during the next 15 years. This plan was available online for review and comment. We also had stakeholder engagement meetings to review our progress and plans. Stakeholder groups that participated in these meetings included the Minnesota Public Utilities Commission, North Dakota Public Service Commission, South Dakota Public Utilities Commission, Minnesota Department of Commerce, Minnesota Chamber of Commerce, Minnesota Large Industrial Group, Wind on the Wires, Izaak Walton League, Sierra Club, Fresh Energy, Minnesota Center for Environmental Advocacy, Center for Energy and Environment, and the Great Plains Institute.

Material topics reflecting feedback We deemed issues material when they rose to the surface in three or more stakeholder groups.
Reliability
1
2
While we have a solid reliability record, we continue to seek ways to improve outage response. We’re researching technology that will allow us to more quickly locate, inform customers about, and restore electrical outages. This research is part of a long-term technology and infrastructure program on which planning efforts began in 2016.
Customer satisfaction Otter Tail Power Company customer satisfaction is among the highest in the nation. To keep it there, we’re installing a new Customer Information System that will allow us to keep pace with evolving customer expectations. In 2016 we began configuring and testing the new system. We expect it to go live in 2018.
Economic impact (direct and indirect)
4
3
Our Community Advisory Boards and other community leaders are interested in the local economic impact Otter Tail Power Company has on the communities we serve. In 2016 we held these meetings in five communities. In 2017 we’ll expand to more communities.
5
Cost In 2016 we asked the Minnesota Public Utilities Commission for permission to increase rates so that we can recover costs associated with our investments in new technologies and infrastructure—investments that will help keep the price our customers pay among the lowest in the region.
Energy efficiency We educate customers about energy efficiency and no- or low-cost ways to use less of our product, because the less electricity our customers use, the more money they save, and the longer we can delay adding more generation resources to our mix. In 2016 we encouraged customer participation in energy-saving programs.
Methodology for ranking topics and stakeholders’ feedback We deemed issues material when they rose to the surface in three or more stakeholder groups. While stakeholders raised other topics of interest, fewer than ten topics had trending feedback. When defining our key topics and issues, we also reviewed material issues presented specifically for electric utilities by GRI’s Sector Guidance, the Sustainability Accounting Standards Board, Ceres, industry organizations, and other electric utilities. Per GRI’s guidance, we’ve identified material topics based on the two dimensions of the materiality principle:

1. the significance of the organization’s economic, environmental, and social impacts and 2. their substantive influence on the assessments and decisions of stakeholders. Our Stewardship Report team reviewed stakeholder feedback documents and created the initial list of issues. The team then shared the issues with relevant subject matter experts and finally with members of our senior management team, including our president, to secure final approval.

Emissions
7
Industry trends show growing concern over the emissions associated with electricity generation. In 2016 stakeholders expressed appreciation for our (then new) air-quality control system at Big Stone Plant in South Dakota, where we’ve been able to reduce sulfur dioxide and nitrogen oxides emissions by 90 percent and mercury emissions by 80 percent. Because this is a topic of great interest, we dedicated a section of this report to covering it in detail.
8
Community engagement We serve 422 communities in a 70,000-squaremile service area in rural Minnesota, North Dakota, and South Dakota. In many of these communities our employees serve on the city council, fire department, school board, or in other prominent roles. We’re an important part of the communities we serve. That’s why our company’s vision statement includes growth and success for our company and the rural communities we serve. We continue to work with local officials and citizen groups to support economic development and improve the quality of life in the areas we serve.
Workforce investments including training and education In preparation for significant employee turnover, primarily due to retirements, we work with area institutions of higher learning on career pathing and recruiting to ensure we have a ready workforce over the next ten-plus years. We also provide training and continuing education opportunities for existing employees to build our bench strength in-house.
9
Charitable contributions Stakeholders in small communities expect large employers to contribute to local charities. In a service area dominated by rural communities, we recognize that our charitable contributions are more important than they might be in larger, more prosperous communities. We connect with our rural communities to support young minds, invest in our current and future workforce, create vibrant culture and vital communities, improve health and human services, and protect our natural resources. We receive countless thankyou letters throughout the year from community organizations expressing their appreciation for our support.

Picture
Company headquarters in Fergus Falls, Minnesota
Getting to know us Our company is named after the Otter Tail River, which provided our first source of electricity when we became an operating utility in 1909. Hundreds of years ago the Ojibwe noted that a large sandspit follows the contour of the shoreline of a lake where the river flows into it. Because they thought this sandspit resembled the tail of an otter, the Native Americans named the lake Nigagwanoe, Otter Tail. By doing so, they also named a river, a village, a township, a county, and a power company. Otter Tail Power Company is a subsidiary of Otter Tail Corporation (NASDAQ:OTTR). Otter Tail Power Company reported $427 million in revenues in 2016, which represents 53 percent of Otter Tail Corporation’s consolidated operating revenues. Both entities are headquartered in Fergus Falls, Minnesota. Otter Tail Power Company provides electricity to more than 131,000 customers in a service area that spans 70,000 square miles in western Minnesota, eastern North Dakota, and northeastern South Dakota. In 2016 Otter Tail Power Company employed 796 people.

ABOUT OUR SUPPLY CHAIN
For the purposes of this report, we’re defining our supply chain to include major suppliers in five primary areas across our three-state service area. 1. Wind farm and combustion turbine sites: Software and information technology hardware, consulting and maintenance services, and parts and equipment repair.
4. Transmission and distribution materials: Poles, conductor wire, connecting and insulating hardware, transformers, and meters. 5. Companywide services: Software and information technology hardware, consulting services, contract labor (including project-based construction workers), recycling and disposal services, and communications and miscellaneous equipment.
Supplier engagement Otter Tail Power Company purchasing agreements require suppliers to abide by federal Equal Employment Opportunity requirements; conform to applicable governmental permits, licenses, and applicable laws; meet or exceed all OSHA requirements; and meet or exceed all reporting requirements for the accidental release of hazardous materials. For large projects we screen construction contractors based on their last five years of safety performance. Software and information technology hardware suppliers are required to adhere to cybersecurity requirements. All suppliers must provide proof of insurance for workers compensation, employer’s liability, auto insurance, and general liability.
2. Coal-fired power plant sites: Fuel, fuel transportation, fuel reagents (pebble lime, powdered carbon, and anhydrous ammonia), operations monitoring and maintenance services, engineering services, and plant upgrades.

GENERATION MIX
Resource Plan filed in 2016 In June 2016 we submitted our 2017-2031 Resource Plan to the Minnesota Public Utilities Commission (MPUC) seeking authorization to add approximately 250 MW of natural gas, up to 300 MW of wind, and approximately 30 MW of solar resources. The plan identifies research and development projects and the most cost-effective combination of resources for meeting our customers’ needs for reliable electric service during the next 15 years. To develop, we evaluate available generation resources and select a plan based on reliability, affordability, and environmental responsibility. The MPUC approved the plan in April 2017. We continue to make existing generating facilities as efficient and economical as possible. Because existing resources alone can’t meet our customers’ future energy needs, the Resource Plan provides a mix of additional resources. While this filing is required only in Minnesota, we develop a strategy for our system as a whole and file the plan with the North Dakota and South Dakota regulatory commissions. With the resources already in service and the planned resources included in our Resource Plan, we expect to have wind energy in excess of our states’ standards.

Coal-fired plants
Combustion turbines
We operate three coal-fired plants that produced about 44 percent of the electrical energy our customers used in 2016.
Combustion turbines produce less than 1 percent of our company’s energy. Because they operate with more expensive fuels, these compact power plants generate energy only when prices for purchasing energy on the energy market are high, typically during periods of high demand or system emergencies.

In June 2016 we filed our Pre-Application Document with the Federal Energy Regulatory Commission to begin the process of relicensing our five hydroelectric plants along the Otter Tail River. The existing license will expire on November 30, 2021. Hydroelectric power has been part of our company’s energy resource mix since 1909 and is the technology on which our founders built the company. We value the hydroelectric plants for their longevity, reliability, and ability to provide renewable energy to our customers.

Our renewable resources forecast
By 2021 we project that our customers will receive more than 30 percent of their energy from renewable resources.
Wind power
We own or purchase approximately 250 MW of installed capacity, or about 18 percent of our retail sales, from wind farms in North Dakota, Minnesota, and South Dakota. In our 2017–2031 Resource Plan, we were authorized to add up to 200 MW of cost-effective windgenerated electricity in the 2018 to 2020 timeframe.

Our Publicly Owned Property Solar (POP Solar) program is one strategy we’re using to meet the state of Minnesota’s requirement for small-scale solar energy. The program provides incentives to tax-exempt public entities to help address system installation costs. The first POP Solar project, finished in 2016, is a 19.5-kW rooftop solar PV system installed at the University of Minnesota-Crookston (UMC) Wellness Center. UMC received a $24,700 incentive to complete the system, which will produce 23,000 kWh annually, or about 6 to 10 percent of the building’s energy requirements.

Thermal generation efficiency Improved operational efficiency contributes to sustainable development by reducing costs and emissions. We always look for ways to maximize the efficiency of our existing thermal generators to ensure we’re operating as economically and environmentally responsibly as possible. In 2016 we improved efficiencies at Big Stone Plant by installing a new variable-frequency drive compressor and upgrading to LED lighting in the boiler building. Coyote Station also underwent LED lighting upgrades for coal conveyor belts and outside areas. Below are 2016 thermal generator efficiencies by fuel type. We calculate efficiency by taking the electric energy produced by our thermal generating units and dividing it by the total energy content of the fuel burned. 2016 thermal generator efficiency by fuel type COAL

Hoot Lake Plant retirement In 2012 we completed a baseload diversification study with a focus on evaluating retirement and repower options for our 1950s-era Hoot Lake Plant. Our study results showed that the lowest-cost option would be to add equipment to comply with Mercury and Air Toxics Standards by 2015 and retire the plant in 2021. We recommended those measures in our subsequent Resource Plans. We’re working collaboratively with the City of Fergus Falls to manage the impact of the planned retirement.
Merricourt wind project
In November 2016 we announced an agreement to purchase a 150-MW wind farm in southeastern North Dakota that EDF Renewable Energy will design and build in 2019. We expect the Merricourt wind project to cost more than $250 million and the wind farm to generate enough electricity to power more than 65,000 homes. The wind energy paired with capacity from a new 250-MW simple-cycle natural gas-fired facility in Astoria, South Dakota, are part of our company’s plan to prepare for the retirement of Hoot Lake Plant, meet our customers’ growing energy needs, and replace expiring power purchase agreements. When the Merricourt wind project is complete, customers will receive approximately 28 percent of their energy from wind. The wind farm will be our company’s largest-ever capital investment.

Line construction will require an average of 75 crew members, with a peak of 150 crew members during the height of construction. Local and regional contractors are working on the project, including in South Dakota: Webster-based Webster Scale, Inc.; Rapid City-based Brink Constructors, Inc.; and Sioux Falls-based Jacobsen Tree Experts, and in Minnesota: Hamel-based Tri-State Drilling and Rosemount-based Dahn Construction.
Multivalue projects We’ve been involved as either investor/owner or owner/project manager with three Midcontinent Independent System Operator, Inc. (MISO) multivalue projects (MVPs), including the two projects highlighted below. MISO defines MVPs as transmission projects that have regional benefits and are part of a regional transmission plan. MISO cost-allocation mechanisms allow recovering project costs from all customers who benefit from them, not only from our customers.
Big Stone South-Brookings County 345-kV line
Construction on the Big Stone South-Brookings County 345-kV Transmission Line project continued in 2016, and we expect it to be in service in 2017. The line will extend 70 miles from Big Stone City, South Dakota, to Brookings, South Dakota. Xcel Energy is the lead developer and is managing construction of this project that’s estimated to cost $120 to $150 million.
Big Stone South-Ellendale 345-kV line
We began construction on the Big Stone South-Ellendale 345-kV Transmission Line project in 2016. As the lead developer, we anticipate the line to be energized in 2019. It will extend 163 miles from Big Stone City, South Dakota, to Ellendale, North Dakota. Our company and Montana-Dakota Utilities Co. own this project that’s estimated to cost $240 million to $300 million.

Big Stone Plant in Big Stone City, South Dakota
Environmental stewardship We recognize the value of this area’s natural resources and concerns regarding climate change and take a balanced approach to these issues by encouraging informed decision making. Because a wholesome environment is essential to a satisfying quality of life, we place respect for the environment at the forefront of our operations. We want our communities and their surroundings to have clean air, land, and water resources. We want them to support wildlife, wildflowers, fish, and local parks. Those are some of the reasons our Environmental Services Department ensures we comply with all environmental laws.
AIR QUALITY
Our company has a long-standing commitment to reduce air emissions. Since 1985 we’ve invested more than $300 million in environmental-control upgrades and efficiency improvements at our fossil fuel plants. By 2020 we project we’ll invest another $8.2 million to comply with U.S. Environmental Protection Agency (EPA) regulations. Since 2007 we’ve invested more than $300 million in wind energy, a zero-emission resource that further reduces our emission intensities systemwide. In November 2016 we announced an agreement to purchase a 150-MW wind farm in southeastern North Dakota that EDF Renewable Energy will design and build 20

in 2019, strengthening our commitment to lowering emissions. Read more about the Merricourt wind project on page 17. The Big Stone Plant air-quality control system (AQCS) saw its first full year of operations in 2016, well ahead of the spring 2017 compliance deadline. We installed the $384 million system to comply with federal and state requirements. Otter Tail Power Company owns 53.9 percent of the plant, so our share of the investment was approximately $207 million. The project resulted in an approximately 90 percent reduction in sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions and an 80 percent decrease in mercury emissions.

Improving power plant efficiency reduces emissions by using less fuel to produce the same amount of energy. Net plant heat rate (NPHR), most commonly expressed as Btu/kWh, represents a measure of the amount of energy it takes to produce one kilowatt-hour of electricity. Our adoption of renewables has contributed to recent improvements in NPHR. Future additions of wind and solar generation will continue this trend.

Since 2000 our tons of SO2 emissions and our SO2 emissions intensity have declined significantly. Total emissions have decreased by 63 percent, and emissions intensity has decreased by nearly 58 percent. Installing a scrubber as part of the AQCS project at Big Stone Plant and continuing the operation of Coyote Station’s scrubber have contributed to the trend along with other plant efficiency projects. Replacing Hoot Lake Plant with wind and natural gas-fired generation will lead to further reductions in SO2 emissions.
Hoot Lake Plant reduced its NOx emissions by approximately 60 percent by installing low-NOx burners and a separated over-fire air (SOFA) system for Unit 3 in 2006 and Unit 2 in 2008. These projects led to a clear improvement in our NOx emissions intensity. The AQCS project at Big Stone Plant and a SOFA installation at Coyote Station in 2016 led to further reductions of plant emissions by 90 percent and 30 percent, respectively. Replacing Hoot Lake Plant in 2021 with wind and natural gas-fired generation will serve to continue our trend of reducing NOx emissions.

RENEWABLE ENERGY
Our power generation includes wind (18 percent) and hydro (1 percent). We also are investing in solar. For details on our current operations and future plans, go to pages 15–17.
WATER RESOURCES
Steam generation requires access to large volumes of water. Our plants fully comply with regulations governing the use of regional water resources as set forth in our water permits. We take great care to ensure we don’t negatively impact the rights of other users. That policy has served us well and has helped ensure a balance between environmental and economic interests. We employ several strategies to conserve water and preserve water quality at our plants, including implementing water-efficient closed-cycle cooling systems at two locations and using dry ash-handling equipment at all generating facilities. We manage water quality to ensure that levels of certain parameters—such as total suspended solids, oil and grease, and metals—in the outflow stay within permit limits to protect environmental and human health. Our company estimates water use through various means, including calculations based on pump ratings and physical methods such as water meters.

Coyote Station Coyote Station appropriates water from the Missouri River under a permit issued by the North Dakota State Water Commission. The plant uses a closedcycle cooling tower to meet its cooling needs. A small portion of the water appropriated for cooling tower operation is discharged to the Missouri River under a permit approved by the North Dakota Department of Health. This thermally heated water travels through an underground pipeline for nearly 25 miles before returning to the river, giving it ample time to cool down. For this reason our state discharge permit doesn’t have a thermal limitation. In 2016 Coyote Station appropriated 4,242 acre-feet of water from the Missouri River and discharged 343 acre-feet back into the river. Over three-quarters of the water appropriated at Coyote Station evaporates after going through various plant processes. The remaining one- quarter is used and recycled within the plant. Heated water is used for oil extraction in western North Dakota. An independent and unaffiliated company, Central Dakota Water Works (CDWW), obtained its own water-appropriations permit from the North Dakota State Water Commission, and Coyote Station uses a water transfer station built in 2012 to fill trucks with water heated by waste heat from our generation process. Coyote Station provided almost 114,000 gallons of heated water to CDWW in 2016.
Big Stone Plant Big Stone Plant withdraws water from Big Stone Lake under a permit granted by the South Dakota Department of Environment and Natural Resources. The permit includes restrictions that limit water withdrawals when the lake is below prescribed levels. During 2016 we withdrew 3,031 acre-feet of water from Big Stone Lake. Virtually all water used at Big Stone Plant is treated and eventually recycled. Big Stone Plant’s unique cooling-water design eliminates the need to discharge heated water or process water into any natural body of surface water. As a zero-discharge facility, Big Stone Plant doesn’t require an industrial wastewater discharge permit from the state. Since 2002 Big Stone Plant has provided the adjacent POET Biorefining ethanol plant some of its process steam to use in the plant’s ethanol production. This is one of the region’s first and largest combined heat and power arrangement of its kind. The arrangement benefits both plants by lowering production costs at the facilities.
Hoot Lake Plant The Minnesota Pollution Control Agency oversees water-quality programs and discharge regulations at Hoot Lake Plant. The Minnesota Department of Natural Resources (DNR) administers water appropriations. Most of the water appropriated for the plant comes from nearby Wright Lake and is classified as either consumptive or nonconsumptive. Consumptive water is consumed within the plant, while nonconsumptive water is returned to the Otter Tail River under the plant’s water discharge permit. Nonconsumptive water generally is used in the plant’s once-through cooling system, where it’s thermally heated by condensers and doesn’t come into contact with any other industrial processes. The plant complies with strict thermal limitations in its discharge permit to protect the aquatic environment. Additionally, the plant’s thermal mixing zone moderates water temperatures immediately after discharge. During 2016 nonconsumptive use totaled 17,904.8 acre-feet of water, and consumptive use totaled 0.7 acre-feet. A total of 17,905 acre-feet was appropriated from Wright Lake, while 0.5 acre-feet was appropriated from groundwater.
BIODIVERSITY
Otter Tail Power Company’s service area is environmentally diverse—from the lakes and forested regions in Minnesota to the plains in North Dakota and South Dakota. Our 5,800 miles of transmission lines and 2,600 miles of distribution lines run through protected areas such as the Chippewa National Forest and can be found adjacent to several federal wildlife refuges and waterfowl production areas. In our commitment to producing and delivering electricity as environmentally responsibly as possible, we use several techniques to protect biodiversity. We conduct environmental assessments and prepare environmental impact statements as required by law when building new assets.
Avian Protection Plan Interactions with power lines and structures have the potential to kill birds, disrupt electric service, violate bird protection laws, and project a poor company image. We’re responsible for minimizing bird interactions with power lines and committed to reducing the number and consequences of these interactions. Our service area includes many species of resident raptors (such as hawks and owls) and smaller birds. The area also plays an important role as a staging, breeding, and nesting ground for many migratory waterfowl species, shorebirds (including the endangered piping plover), and raptors (such as bald eagles and ospreys). Endangered whooping cranes also migrate through our region.
National Pollutant Discharge Elimination System permits National Pollutant Discharge Elimination System (NPDES) permits cover the return of public waters to their watersheds. The states where we do business issue the required NPDES permits. We remain in compliance with all our NPDES permits. Industrial use of public waters is essential to our operations, and compliance with our permits is critical.

Transmission and distribution lines that have experienced avian electrocutions are assessed for risk of future electrocutions. Certain structures may be determined to be suitable for retrofitting. Retrofitting may consist of altering the structure framing by isolation, insulation, installation of perch discouragers or similar apparatus, or a combination of these actions. Agencies such as the U.S. Fish and Wildlife Service and state game and fish departments also may offer recommendations. All new transmission lines are constructed to avian-safe standards. We’ll continue to monitor for high bird use areas based on scientific literature, input from federal and state environmental professionals, and observations from company field personnel. We’ll also continue to evaluate and implement measures that reduce or eliminate the risk of collision and electrocution, such as insulating and separating equipment and lines, marking power lines, and providing substitute perches and nest sites.
Wind farms and birds Wind is a low-cost, clean, and renewable source of power that is abundant in our service area. Wind farms have the potential to affect migratory bird populations. Birds may inadvertently fly into turbine blades, resulting in injury or death, known as “take.” See page 16 to view the locations of our wind turbines. As the operator of our wind facilities, NextEra Energy regularly inspects our turbines, records all avian take, and reports mortalities of threatened, endangered, or otherwise protected birds to the U.S. Fish and Wildlife Service. Over the last decade of operation, our turbines have resulted in the take of fewer than ten migratory birds a year, of which none have been identified as threatened, endangered, or otherwise protected. Most of these birds were waterfowl species, such as ducks. In 2016 only one reported incident of take occurred at our wind turbines. Developers will design the Merricourt wind project to minimize impacts to birds to the greatest extent possible.
Osprey nest removal permits
In 2016 we relocated approximately five osprey nests from power structures in northern Minnesota. Ospreys build large nests on high structures with views of the surrounding environment. We work with the Minnesota DNR to obtain nest removal permits to relocate these nests. We usually erect artificial nesting platforms near the original nest to provide a safer environment for the ospreys to raise their young.

Other endangered species Although the endangered pallid sturgeon hasn’t been found in the stretch of the Missouri River from which Coyote Station appropriates water, it’s a potential habitat. We employ a closed-cycle cooling system, which the EPA has classified as a Best Available Technology for reducing fish mortality at cooling water intake structures.
Restoring other habitat In 2016 we continued to relocate existing ash near Hoot Lake Plant and restore riparian habitat by widening the river channel in certain areas and creating a flood plain along the Otter Tail River. As part of the restoration project, we’re working with the Minnesota DNR to provide suitable spawning and nesting habitat. Restoration activities still are underway. When the project is complete in 2017, we’ll have restored habitat along approximately 3,300 feet of the Otter Tail River.
SPILLS, FINES, AND SANCTIONS
Despite our commitment to sound environmental stewardship, rare mistakes and uncontrollable events occur. When they do, we correct them as quickly as possible. The Environmental Services Department ensures compliance with our environmental permits and regulations. In the event of noncompliance, we work with regulators to ensure the instance is mitigated and the noncompliance event is not repeated. We train our employees to be aware of our environmental permit requirements and the steps they need to take to stay in compliance.
Spills In 2016 equipment failures caused minor oil spills. The most significant one involved approximately 100 gallons of non-polychlorinated biphenyl (non-PCB) transformer oil that spilled during an ice storm. We promptly reported the spill to the appropriate authorities and hired a contractor to clean up and restore the area to its original condition.
Fines and sanctions In 2016 no fines, sanctions, or notices of violation were assessed to our company for environmental infractions.
Waste by type and disposal method Fly and bottom ash
The process of generating electricity produces wastes as byproducts. Almost all of the wastes are classified as nonhazardous, and we dispose of them in on-site landfills.

Electricity distribution systems require oil-containing transformers. Although we’ve taken steps to remove PCB oil from our larger substation transformers and regulators, a small percentage of electrical equipment within our distribution system does contain PCBs. When old equipment is retired, we test for PCBs and dispose of them properly. In 2016 we disposed of approximately 11,481 pounds of PCB material. Should a leak or release occur from a unit potentially containing PCBs, it’s our policy to test the released material for the presence of PCBs and promptly clean up and dispose of any contamination according to state and federal standards.
ENERGY RESOURCES AND FUEL SUPPLIERS
We examine new energy resources and fuel suppliers to ensure they have a history of compliance with all regulatory and legal environmental requirements and have a record of responsible business practices. We often procure short-term energy from a supplier without identifying a specific generating resource, so environmental criteria isn’t applicable. In 2016 we engaged in two notable supplier agreements, which we worked to ensure met all environmental requirements. In May Coyote Creek Mining Company, LLC, a subsidiary of North American Coal Corporation, began supplying lignite coal to Coyote Station. In November we announced an agreement to purchase a 150-MW wind farm in southeastern North Dakota that EDF Renewable Energy will design and build in 2019.
REGULATORY PROPOSALS AND PUBLIC POLICY ENGAGEMENT
Fossil fuel-fired plants are subject to many regulations that the EPA either has promulgated recently or is in the process of revising. The exact impact of these rules is difficult to predict because challengers typically question through court action whether the EPA is adhering to key restrictions and obligations. The outcome of these challenges notwithstanding, regulatory uncertainty will continue to impact our planning and operations. We’re paying particular attention to the following rules that the EPA is developing or has developed recently.
Coal Combustion Residuals Rule Regulatory background
In June 2010 the EPA proposed regulating coal combustion residuals (CCR) as either hazardous or nonhazardous waste. In December 2014 the EPA signed a final rule categorizing CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act (RCRA). The new rule is self-implementing, which means the rule relies on citizen and state involvement with no federal enforcement. Highlights of the rule include: • Establishing a webpage with information about the design, operation, environmental monitoring, and corrective actions required at CCR landfills and surface impoundments. • Installing additional environmental monitoring equipment, such as groundwater monitoring wells. • Evaluating previously unpermitted sites to ensure their conformance with the new rule.

• Designing landfill and surface impoundment liners and capping systems to one national standard. • Closing unlined surface impoundments if groundwater monitoring indicates a statistically significant increase of chemical concentrations above the background levels for the unit. We completed the tasks necessary for rule compliance to date and are well prepared for adherence to the future requirements the regulation will phase in over the next few years. Even though the EPA has chosen to regulate CCR under Subtitle D, it reserves the right to regulate the material under Subtitle C as more data becomes available. We continue planning and investing resources to maintain compliance with this rule, including plans for capital projects at Coyote Station and Big Stone Plant.

and 111(d) rules and, if appropriate, to suspend, revise, or rescind the rules. Given the change in EPA administration in 2017, uncertainty regarding the status of carbon dioxide regulations likely will continue.
Otter Tail Power Company impact
We’ve taken significant steps to reduce our systemwide CO2 emissions intensity. We were concerned about the disproportionate impacts the final CPP would have had on the states that we serve and that the final rule didn’t recognize the lawful authority of individual states to establish 111(d) standards of performance.
Challenges
We continue to monitor the status of litigation and political changes and their effect on CO2 regulations.
Effluent Limit Guidelines Rule
We evaluated our CCR units, both landfills and surface impoundments, to ensure conformance with the new rule. In 2016 we developed new webpages (ccr-cs.net, ccr-bsp.net, ccr-hlp.net) that allows the public to quickly access information about the design, operation, maintenance, and environmental monitoring of our CCR units. We’ve installed additional environmental monitoring at several sites. As we expand landfills or ponds, we’ll incorporate national standards in the units’ designs.
Regulatory background
Challenges
No discharges from any of the waste streams regulated by this new rule occur at any of our generating plants. This means we should see no impact to operations or NPDES permits resulting from this rule. The new requirements are based on the Best Available Technology Economically Achievable (BATEA) for controlling discharges of pollutants. At Hoot Lake Plant, we already use the BATEA for flue gas mercury control, fly ash transport, and bottom ash transport, which is dry handling. At Coyote Station and Big Stone Plant, the scrubber systems, flue gas mercury controls, and fly ash transport systems already use the BATEA (dry handling). Both plants use wet sluicing systems for bottom ash transport, which is not the BATEA. However, these waste streams are not discharged from our sites. The EPA has specifically stated that internal waste streams for the above categories of wastewater are acceptable as long as those streams never are discharged.
The EPA’s withholding of the final classification of CCR is our most significant challenge. By not making a final determination, the EPA still may propose more stringent and expensive disposal options. Restrictions on beneficial use will limit the amount of CCR able to be recycled. We continue to evaluate options for operational changes to better position ourselves for rule compliance.
Greenhouse gas regulations Regulatory background
In October 2015 the EPA published final New Source Performance Standards (NSPS) under Section 111(b) of the Clean Air Act to limit carbon dioxide emissions from new power plants. On the same day the EPA published a final rule regulating carbon dioxide emissions under Section 111(d) of the Clean Air Act affecting existing power plants. The 111(d) rule, often termed the Clean Power Plan (CPP), set individual CO2 emissions intensity limits on each state. In February 2016 the U.S. Supreme Court granted a stay of the rule. In March 2017 President Trump issued an Executive Order requiring the EPA to review both the 111(b)

In November 2015 the EPA published the first significant revision of the steam electric effluent limitation guidelines under the Clean Water Act in more than 30 years. The rule sets technology-based effluent limitations on certain types of discharges at steamelectric-generating facilities. Most of the revisions set limits on water discharge that has come into contact with various types of coal combustion byproducts.

We’ll continue to manage water onsite to ensure that regulated waste streams at Big Stone Plant and Coyote Station never are discharged.

The act sets an aggressive statewide energy-conservation goal of 1.5 percent of average annual Minnesota utility retail sales. During 2016 we invested more than $7.8 million in CIP and returned more than $49.7 million in lifetime net benefits to customers. Energy savings reached a recordbreaking high for us at 57.6 million annual kWh of energy and more than 17.3 MW of demand. For the year, that is 2.75 percent of our annual retail sales. At a lifetime cost of less than 14 cents per kWh conserved, our energyefficiency programs continue to be a cost-effective resource for customers.
In addition to designing programs to meet conservation goals, we’re working to ensure that savings estimates are measurable and verifiable to meet stringent state program requirements. We highlight below some of the more than 30 Minnesota programs offered in our CIP portfolio.
Energy-efficient lighting
Our commercial lighting retrofit program continues as one of our most successful commercial energy-efficiency programs. In 2016 more than 1,085 participants installed systems that are expected to save approximately 17.51 million kWh annually during the life of the technology. With our Be Bright program, we partner with local retailers to offer our residential customers point-of-sale rebates on Energy Star-qualified compact fluorescent lightbulbs (CFLs) and LED lighting.
Heat pump rebates
Rebates encourage customers to install energy-efficient air-source or geothermal heat pumps. The program, which saved nearly 5.87 million kWh in energy sales for the year, is designed to reduce both winter and summer peak demands as well as overall energy use.
Energy-efficient equipment grants
Our custom grant program taps the conservation and efficiency potential of commercial and industrial operations by partially funding cost-effective energyconservation projects. During 2016 we provided 61 custom grants to customers with a total projected savings of approximately 7.37 million kWh of energy and 1,298 kW of demand.
The American Council for an Energy-Efficient Economy spotlighted our company as a Top Performer in its 2016 report Big Savers: Experiences and Recent History of Program Administrators Achieving High Levels of Energy Savings. We were one of 14 energy-efficiency program leaders featured in the study. The report noted our highly cost-effective and expanding energy-savings program despite the rural and expansive nature of our service area. ACEEE deemed our demand response and behavioral energy savings programs as innovative sources of energy savings. The report is available at aceee.org/research-report/u1601.

Motor and adjustable-speed drive rebates
Replacing used or burned-out standard-efficiency motors with energy-efficient motors reduces energy use and operating costs in industrial plants and commercial buildings. Installing adjustable-speed drives (ASDs) can improve system performance and energy efficiency. During 2016 our customers installed and received rebates for approximately 260 efficient new, replacement, or retrofit motors and 290 ASDs with projected savings of approximately 7.45 million kWh of energy and 1,185 kW of demand.
CoolSavings
Residential customers enrolled in CoolSavings earn a $7-a-month bill credit June through September in exchange for permitting us to cycle their central air conditioners 15 minutes on and 15 minutes off during peak periods of energy use. During 2016 approximately 115 of our Minnesota customers, including approximately ten units for commercial customers, enrolled in the program. Across the three states we serve, approximately 1,860 customers are enrolled.
Appliance recycling
Our appliance recycling program encourages customers to recycle working but inefficient refrigerators and freezers to receive a $50 rebate. In 2016 the program recycled and rebated approximately 465 appliances.
House therapy
Our house therapy program offers income-qualified customers LED bulbs, controlled water-heating equipment, and refrigerator and freezer replacement. Customers with electricity as their primary heat source also are eligible for home weatherization services, including weather stripping and insulation. Offered through a partnership with Minnesota Community Action Agencies, this program served approximately 125 homes in 2016.
Student energy kits
In 2016 we distributed approximately 430 energy kits to middle school students. The home kits contained LED bulbs, engine block heater timers, as well as information about these products, installation instructions, and energy saving tips. Through this program our customers saved approximately 240,310 kWh and 14.45 kW of demand, and students deepened their awareness of energy conservation.
Energy feedback
Our energy feedback program delivers energy-use information to customers by mail and online. It’s a successful and significant part of our residential portfolio of conservation programs. With approximately 36,000 residential customers in the program, each household in 2016 received up to six reports that
In addition to benefiting industrial and manufacturing customers, our custom grant program provides a way to improve public facilities. The Morris Area School District combined a lighting retrofit with custom grant programs for an annual energy-cost savings of $85,000. Additional savings came from lower maintenance costs and the program rebate.

outlined how its energy use compared with similar homes in the area. Customer savings averaged 300 kWh per household. Home Energy Analyzer is an online service that residential customers opt to use. It incorporates bill history and calculator tools that help customers find personalized ways to save. In 2016 approximately 1,330 Minnesota customers saved an average of 625 kWh per household. In 2016 overall savings with these two energy feedback programs totaled almost 11.7 million kWh.
Energy efficiency filings in Minnesota Our Minnesota CIP triennial program, approved in November 2016, established new portfolio programs and an energy savings goal of 1.7 percent for 2017-2019. Because the Minnesota Public Utilities Commission recognizes energy efficiency as a resource in planning to meet future energy needs, the new energy savings goal supports our 2017-2031 Resource Plan. See page 12 for more information about our Resource Plan.
South Dakota Energy Efficiency Plan Our South Dakota residential and business customers continue to require less electricity thanks to energyefficient technologies available to them through our Energy Efficiency Plan (EEP). This conservation plan encourages businesses to install energy-efficient lighting, motors and drives, air-source and geothermal heat pumps, and custom efficiency improvements. The plan encourages our residential customers to take advantage of our CoolSavings air-conditioning control program and offers incentives for installing energy-efficient lighting and air-source and geothermal heat pumps. Results for 2016 show that we invested approximately $362,300, returning more than $3.3 million in lifetime net benefits for customers. Customer energy savings reached 2.84 million kWh, which was 101 percent of our 2016 EEP goal. Regulatory requirements included completing a triennial program filing in May 2016. The plan established a new program portfolio and goals for 2017-2019 and was approved in November 2016.
North Dakota energy conservation We continue to offer demand-response programs and incentives to our North Dakota customers. North Dakota regulators have not approved an energy-efficiency plan.
To expand the network of electric vehicle charging stations available to drivers in our service area, in July 2016 we worked with the City of Bemidji, Bemidji State University, and North Country Electrical Services, Inc., to purchase and install three level-two charging stations. They are near City Hall, Paul Bunyan Park, and Bemidji State University. In addition, we offer our customers rebates and off-peak rates when they install qualified charging stations for their electric vehicles.

In February 2016 we submitted an electric rate case to the Minnesota Public Utilities Commission (MPUC). A rate case is a regulatory proceeding to determine the cost our company incurs to provide our customers with electric service and how much we should charge customers for that service. Key drivers for the rate case included new environmental technologies, a strengthened delivery system, and overall rising costs. In March 2017 the MPUC granted a $12.3 million increase to our base electric rates. The average residential customer will see an overall average increase of approximately $5.10 a month. The average business customer will see an overall average increase of approximately $9.40 a month. Even with this increase, our rates remain among the lowest in the region and in the nation.

Cost projections
We’re taking proactive steps to keep the price our customers pay for electricity as economical as possible. New technologies and infrastructure investments, which cost less than other options to produce and move lowcost energy, will help to keep our prices affordable. And our programs, some of which are mentioned on pages 29-31, can help customers use electricity wisely and save even more. While we’ve selected low-cost options to meet customer needs, they still come with a price. We anticipate that all customers averaged together will see a bill increase of about 3 to 4 percent a year through 2020. The increases will vary by state, year, and size.

High customer participation in our direct load-control rates makes our company unique among utilities. With one-third of our customers partnering with us in load management, we’re able to curtail a portion of their electrical load during periods of high demand, high energy prices, or system maintenance. Participating customers save on their energy bills with rates that are less than our standard electric rates. We accredited with the Midcontinent Independent System Operator (MISO) a portion of our direct loadcontrol capacity, making it available on a limited basis during MISO system peaks. The amount accredited varies monthly and is set as 90 MW in January, February, and December; 55 MW in March, April, and November; 25 MW in October; 18 MW in June, July, August, and September; and 15 MW in May. Accrediting a portion of the demand resources is a step to further enhance regional transmission reliability. Our Resource Plan calls for demand-side management resources to increase annually to reach approximately 8 MW of additional summer-season peak-load-reduction capability through 2031. To achieve this, during 2016 we connected an additional 12.7 MW of controlled winter-season load and 3.6 MW of controlled summerseason load.
NEW CUSTOMER INFORMATION SYSTEM
Our Customer Information System (CIS) performs billing, processes payments, and manages customer account information such as account balances, payment programs, and participation in demand-side management. After we named the CISone project team members in January 2016, we began implementation with our vendor, Cayenta, in February. The new system will provide better workflow, integrate with other company systems, provide more automation, and give our customers easier access to online options. We’re targeting an in-service date in 2018.

A late December 2016 storm showed that our customers and employees are resilient. The dangerous storm produced wicked winds, blinding snow, and terrifying ice that broke power lines and laid flat the poles that carry power to many customers in South Dakota and North Dakota. Crews braved the elements night and day to restore power as safely and efficiently as possible. We received the Edison Electric Instituteâ&#x20AC;&#x2122;s Emergency Recovery Award for our restoration efforts during and after the storm. The award recognizes member companies that faced difficult circumstances as a result of extraordinary events and put forth an outstanding effort to restore service promptly to the public.

Cybersecurity
Compromises to cybersecurity pose a serious threat to the privacy of customer data and to the reliable operation of the bulk electric system. To mitigate risk, we continue to secure systems and software and to educate and train employees on security and awareness. In addition, the Federal Energy Regulatory Commission approved Version 5 of the Critical Infrastructure Protection Cybersecurity Standards. To comply with these standards, we’re securing software, identifying impacted facilities, and drafting supporting policies. The standards require us to categorize our cyber assets as high, medium, and low impact. • On July 1, 2016, our high- and medium-impact cyber assets were in compliance. These cyber assets must be programmable and located at certain control centers and generation and transmission facilities identified in the standards. • On April 1, 2017, our low-impact cyber assets for incident response/cybersecurity awareness were in compliance. • By September 1, 2018, our low-impact cyber assets must be in compliance for physical and electronic access controls. We are on track to comply.
Vegetation management Pruning and removing trees on a five-year systemwide cycle reduces vegetation- and animal-related outages. In 2016 we spent about $1.1 million on vegetation management for our transmission system and about $1.95 million for our distribution system.
Asset Replacement Plan We’re enhancing our Asset Replacement Plan for our critical assets to improve system reliability, reduce the median age of our assets, and establish adequate funding levels for the plan to be successful. These critical assets include substation transformers and voltage regulators, circuit breakers, poles, and underground cable.
PREPAREDNESS PLANNING
Our company has approximately 20 situation-specific documents that provide a systematic approach to managing crises without causing major disruption to normal activities. These documents, some of which are outlined below, are general guidelines we supplement with employee education and training. Our company’s various preparedness plans incorporate recommendations and compliance measures from: • Federal Emergency Management Agency. • Midcontinent Independent System Operator, Inc. • North American Electric Reliability Corporation. • Federal Energy Regulatory Commission. • Other key agencies.
Emergency-response guidelines
Each employee has a copy of our company’s emergencyresponse guidelines, which we provide to help ensure employee safety should an emergency or disaster occur. Emergency procedures that we cover in the guidelines include medical, fire, tornado, workplace violence, building evacuation, bomb threat, and suspicious mail and objects. Our Safety Services Department periodically reviews the emergency-response guidelines.
Crisis Response Communication Plan
Our Crisis Response Communication Plan is a thorough, step-by-step checklist that includes a first-hour response plan, key contacts, and situation-specific procedures for major crises. We review and distribute the plan annually.
System-restoration plans
In the spring and fall of each year we and our neighboring utilities run drills based on our respective system-restoration plans. The purpose is to exercise the procedures and processes required to restore the bulk electric system from a blackout condition. By understanding system behavior and having jointly developed and proven procedures in place, Otter Tail Power Company and neighboring utilities help ensure continued system reliability for the region. Because reliability is one of our primary concerns, we also maintain a backup control center, which would allow us to work with neighboring utilities if our primary control center were to become unusable.

EMPLOYEE COMMITMENT
We offer our employees competitive compensation and benefits, promote a safe work environment, and challenge employees to excel. Our Human Resources Department administers a compensation and benefits program that helps us attract and retain a quality workforce to provide our customers with reliable and economical service. We endorse our Affirmative Action and Equal Employment Opportunity Plans. And we provide open channels of communication with our employees. For our bargaining unit employees (50 percent of our workforce), we define a grievance process within our Collective Bargaining Agreements. Our 796 employees in Minnesota, North Dakota, and South Dakota expect and deserve a safe workplace where they are challenged, rewarded, and respected. Company leadership works to ensure this. Upon retirement, the average employee has approximately 32 years of service.
Otter Tail Women Networking and Integrating Talent
Women in executive and management positions comprise Otter Tail Women Networking and Integrating Talentâ&#x20AC;&#x201D;OWN IT. In concert with our companyâ&#x20AC;&#x2122;s employee development program, the group provides formal and informal support channels for women in our company and works to increase awareness of unintended bias in the workplace. In 2016 the group facilitated two events that included small-group discussion among non-managerial women and company leaders on resilience, gender equality, and work-life balance. Area business leaders provided keynotes followed by question-answer sessions and networking opportunities. OWN IT also facilitated an opportunity for 12 women leaders from Otter Tail Corporation companies to meet astronaut Karen Nyberg to discuss workplace gender equality and the role of art with science, technology, engineering, and math in preparing tomorrowâ&#x20AC;&#x2122;s workforce.
Our workplace diversity
Weâ&#x20AC;&#x2122;re an Equal Opportunity Employer with policies and practices that are nondiscriminatory. Our workforceâ&#x20AC;&#x2122;s ethnic diversity reflects the demographics of the population we serve. For example, ethnic minorities represent approximately 5 percent of the population of Fergus Falls, Minnesota, where approximately 400 of our employees work. Our Human Resources Department ensures that we comply with all laws regarding labor practices and that we have an inclusive work environment where talented people thrive. We respect and value diversity among our employees and all those with whom we do business, and we hold every employee accountable for guaranteeing a workplace free of discrimination and harassment.

Employee compensation and benefits
To help retain a skilled workforce through competitive benefits, we routinely benchmark our compensation policy. Our most recent study, conducted by Mercer Consulting in 2015, benchmarked approximately 100 nonunion positions in the energy industry sector with similar revenue size to Otter Tail Power Company to accurately reflect the market value of total compensation (base salary plus incentive). On aggregate, our total compensation was 1 percent above the competitive market median. In addition to vacation, paid holidays, and sick leave, we offer our employees the following benefits: 2016 employee benefits BENEFIT

We anticipate 35 percent to 40 percent of our workforce will reach our average retirement age within the next ten years, taking precious skills and expertise with them. We continue to address this projected labor shortage in our internal succession planning process and by working with current employees to improve efficiencies. And in 2016 we hired to fill 105 positions.
We provide recruitment materials to educational institutions and other sources as outreach to potential employees. For example, we distribute Powerful Possibilities, our career guide, to area high school and college career services offices. It features overviews of jobs in customer service, engineering, and plant and field operations. We also support scholarship programs and internships, participate in job fairs, and accept speaking engagements. We have ties to post-secondary programs and employee involvement in multiple advisory committees at area institutions of higher learning, including: • Bismarck State College Bismarck, North Dakota • Lake Area Technical Institute Watertown, South Dakota • Minnesota State Community and Technical College Fergus Falls and Wadena, Minnesota • Mitchell Technical Institute Mitchell, South Dakota • North Dakota State College of Science Wahpeton, North Dakota • North Dakota State University Fargo, North Dakota • Northwest Technical College Bemidji, Minnesota • South Dakota State University Brookings, South Dakota • University of Minnesota Crookston and Morris, Minnesota • University of North Dakota Grand Forks, North Dakota
