River FROM: STEPHEN ROHLF, BUILDING AND ZONING ADMINISTRATOR S'k DATE: SEPTEMBER 26, 2000 SUBJECT: CONDITIONAL USE PERMIT FOR METRO WIND, LLC CASE # CU 00-35/P.H. Request Metro Wind, a Minnesota based company, is proposing to construct a wind turbine with a maximum capacity of 660 kW. Wind turbines are a conditional use in the A-1/ Agricultural Zone. Attachments Vicinity map, site plan, and narrative supplied by Metro Wind. Site The proposed site for the wind turbine, owned in trust by Ernest and Doris Toth, is zone III A-1/Agricultural. The site is open and without wetlands. A vicinity map and legal description of the property are included in the information supplied by Metro Wind, which is attached to this memo. The site is located just east of US Trunk Highway 169 north of 225th Avenue. Staff's Review Metro Wind has done a good job of describing their wind turbine in their narrative. The turbine will set atop of a tubular monopole with access through the center via a secured door. The associated transformer will be in a fenced enclosure. No trees or wetlands will are required to be disturbed for the construction of the wind turbine. When one of the three blades is pointing upward, the maximum height is 237 feet. The wind turbine will roughly produce enough electricity for 75 to 100 homes a year, depending on how windy it is. Elk River Municipal Utilities (ERMU) will wheel the electricity (carry it through their transmission lines) and it will ultimately be part of Northern States Power's "Green Power" efforts. ERMU already has the necessary transmission lines in the area of the wind turbine. A warning siren is needed in the general area of the proposed wind turbine. The Elk River Fire Department is working with Metro Wind regarding hanging this siren on the wind turbine's tower. Ill 13065 Orono Parkway • P.O. Box 490 • Elk River, MN 55330 • TDD & Phone (763) 441-7420 • Fax (763) 441-7425 City staff along with Metro Wind held a meeting at the proposed wind generator site with adjacent property owners on July 25, 2000. Issues and concerns raised at this meeting III include: Noise—The new generation of wind turbines are relatively quiet. The noise generated is proportionate to the speed of wind. The wind tends to mask the sound of the wind turbine. Birds—Groups like the Audobon Society have expressed concerns regarding the effects of wind generators on birds. It is staff's understanding that this concern originated when wind turbines were placed on top of grid type towers. Pigeons and other birds would use these structures to nest and raptors would dive in to catch them and be hit by the wind turbine's blades. Metro Wind's propose wind turbine will set on top of a monopole, eliminating any nesting areas. Property Values—This is always a hard issue to talk definitively about. All property values in Elk River, no matter what is in the general area, have been increasing significantly. Small single-family lots with city sewer that are adjacent to structures similar to the wind turbine, water towers, have not had their property values suffer. The area where the wind turbine is proposed is quit rural, so it should be even less of a factor than a water tower in the urban area of the city. Safety—One safety issue that was not brought up in Metro Wind's narrative is the issue of the wind turbine collapsing. The wind turbine's tower is design to III collapse onto itself, not tip over. Energy City As you are probably aware, the City of Elk River has been designated as Energy City by Minnesota's energy industries. Energy City was created to act as a geographical focal point for demonstrating renewable energy and energy efficient technologies, services, and products. Metro Wind is a significant partner in Energy City. By choosing Elk River to locate a wind turbine they hope to demonstrate that, even on the low end of the commercial wind resource, wind power can still make economic sense. Diversifying our sources of energy is an important push by both the Minnesota Department of Commerce and the US Department of Energy. Wind is a clean logical source of energy. Recommendation Staff recommends approval of Metro Wind's request, conditioned on the wind turbine and associated facilities being constructed as presented in their application. III CONDITIONAL USE PERIMIT REQUEST • METRO WIND,LLC INTRODUCTION Metro Wind LLC ("Metro Wind") is a Minnesota limited liability company which proposes to construct and install one commercial size wind energy turbine on a parcel of land described as that portion of the West %, SE '/,, Section 3, Township 33 North, Range 26 West of the Fifth Principal Meridian, lying north and westerly of 225`h Street (the "Site"). Metro Wind is applying for a conditional use permit to construct and operate the turbine and related facilities for a period of 30 years after construction is complete and the turbine becomes operational. Metro Wind is submitting the required application and fees; ten sets of drawings depicting the site and the proposed facilities; and this discussion of the information required by Section 900.42 of the Elk River Zoning Ordinance. I. THE DEVELOPER Metro Wind is an affiliate of Northern Alternative Energy, Inc. ("NAE"), a Minnesota company headquartered in Minneapolis, which develops, owns and operates commercial wind energy facilities. In Minnesota, NAE owns and operates two large windfarms in Lincoln County with a combined capacity of 23.13 megawatts (MW) and a 600 kilowatt (kW) facility in Marshall. NAE also operates projects in Iowa and has constructed projects for others in • Wyoming and Wisconsin. Through affiliates, NAE is constructing 32.91 MW of new wind generation this year in Minnesota. NAE was selected in April by Northern States Power Company ("NSP") to construct an additional 50 MW of wind generation and 300 MW of natural gas generation in 2001. Among wind developers in the United States,NAE is not the largest,but is of medium size and growing at a moderately rapid rate. NAE was founded in 1992 by Greg Jaunich, who remains President. Since its creation, NAE has added professional accounting, project management and engineering capabilities, and has established relationships with outside experts to assist in construction (M.A. Mortenson Company, Inc.) and environmental analysis and permitting (HDR Engineering, formerly known as Braun Intertec). Mr. Jaunich serves on the Board of Directors of the American Wind Energy Association (AWEA), and AWEA recently recognized NAE's accomplishments by bestowing it with an award for Outstanding Commercial Achievement. NAE's purpose as a company is to promote the environmentally responsible development of wind energy facilities in order to increase the use of wind energy as a component of the country's power supply resources. By doing so, NAE hopes to provide significant environmental benefits by replacing other forms of electric generation which create pollutants and other adverse environmental impacts. In the course of developing its wind facilities,NAE is also committed to avoiding adverse environmental impacts to the fullest extent practicable and to cooperation with landowners and local residents to minimize concerns and impacts. • • II. THE PROPOSED PROJECT A. Summary Description Metro Wind's proposed project will consist of one wind turbine with a nameplate capacity of 660 kW, which could be characterized as a medium-sized turbine. The turbine is a V-47 model manufactured by Vestas, a Danish manufacturer which is a longstanding turbine manufacturer and the largest such manufacturer in the world. The turbine is located on top of a freestanding steel enclosed tubular tower which, in turn, is attached to a concrete foundation buried below grade. A small pad-mounted transformer typically is located adjacent to the turbine foundation pad. An access road for maintenance purposes will be constructed between the turbine and public road. The power generated by the turbine is transmitted from the transformer through underground electric lines to a point of interconnection with lines owned by Elk River Municipal Utilities ("ERMU"). ERMU will then transmit the energy to transmission system facilities owned by Great River Energy and, ultimately, to NSP. Metro Wind has entered into a power purchase agreement with NSP pursuant to which NSP agrees to buy the entire output of the wind turbine. Metro Wind will install the equipment needed to interconnect the turbine with ERMU's system and operate the turbine in a manner which will not adversely affect the operation of ERMU's system or ERMU's customers. B. The Project Site • Metro Wind selected the Site for development due to the quality of the wind resource at the Site and its location in an area currently occupied by similar industrial and commercial uses. The Site is part of a parcel owned by a trust for the benefit of Ernest and Doris Toth(Toth Trust). Maps depicting the Site and its characteristics are included with this application. The bulk of the Toth property south of the Site has been used for gravel mining and related purposes for many years, and is currently being mined by Bauerly Brothers pursuant to an Agreement for Issuance of Conditional Use Permit dated June 23, 1997. The Site lies immediately north of the gravel mining activities across 225th Street, and is about 2.5 acres in size. ERMU maintains a distribution line south of and adjacent to 225th Street into which the Metro Wind project will connect. The Site is currently vacant and occupied by brush and wooded area. There are no structures or improvements on the Site. Until recently, the Site was subject to Bauerly Brothers' lease for mining with the landowners and was permitted for that use. There are no wetlands on the Site, or any other protected or endangered species or land use. The Site is zoned A-1, which permits wind generators in areas zoned in this manner. The construction and operation of the Project will result in limited changes to the Site. The turbine will be located at a point shown in map A-2 at the top of a small knoll. The turbine is set back from the Site boundaries as far as practicable, and the access road will connect with 225th Street as shown on map A-3. Lines from the turbine will be buried to the point where they cross 225th Street to intersect with ERMU lines within ERMU's existing easements. See map A- • 2. Once construction is complete, only about .5 acres will be occupied by turbine and wind 2 facilities, and the balance of the Site will remain unaffected. Elevations at the Site and its • drainage characteristics will be unchanged. There will be no lighting at the turbine except to the extent a light on the blade tips or at the top of the turbine nacelle is required by the Federal Aviation Administration. No signage is planned. No curb and gutter is required. Parcels surrounding the Site include pasture and the gravel mine to the south and east; cultivated fields to the north and east; and a single-family residence on a parcel immediately west of the Site. The residence is approximately 500 feet due west of the turbine. See Appendix A-2. C. Other Environmental Impacts Several other issues are commonly raised when wind turbines are sited, each of which has been extensively studied and each of which is addressed below. 1. Noise. Turbines create noise during operation. The Vestas V-47 does not create any problematic tones. In addition, with an adequate setback from receptors, as here, no perceptible increase in noise should occur beyond the Site. The turbine is expected to operate within all applicable Minnesota Pollution Control Agency noise regulations. 2. View. The turbine will be visible from a considerable distance. The height of the tower and turbine at the hub of the turbine rotors will be about feet. The • rotor diameter, the diameter of the area swept by the turbine's three blades, is about 154 feet. While the tower, turbine and blades will be painted relatively unobtrusive colors, the facility will be visible. Public perceptions of such turbines often conflict. Some persons do not appreciate the view; others appreciate what the turbine represents. In any event, there is a limit to the mitigation opportunities for addressing this issue. 3. Wildlife. There has been a considerable amount of research with respect to the tendency of wind turbines to increase mortality among birds who collide with the turbines. Studies have been conducted worldwide at a large number of wind facilities. In Minnesota, an extensive five-year study of turbines and their effect on bird populations was recently concluded, focusing on the Buffalo Ridge area in Lincoln and Pipestone Counties which currently contains over 300 turbines. In that area, with a large resident bird population and significant migration activity, it was concluded that no significant increase in avian mortality had occurred. In a more densely populated area such as that surrounding the Site, a similar result is expected. No other wildlife should be affected. 4. Emissions. There are no emissions, releases or discharges from normal operation and maintenance activities. 5. Decommissioning. The power purchase agreement with NSP has a scheduled • term of 30 years, ending by approximately December 31, 2030. At that time, • 3 Metro Wind is obligated under the terms of its lease with the Toth Trust, to . remove all facilities aboveground and to remove the foundation and other below grade improvements to a depth of four feet below grade. See Appendix C. 6. Safety. The supporting tower is made of smooth steel with a steel entry door at the base through which operation and maintenance personnel enter. When not in use, the access door will be locked and secured. There is no other means of climbing or scaling the tower. Other exposed facilities will be fenced or otherwise secured to prevent damage or accidental or intentional access. CONCLUSION Metro Wind believes its proposed facility is compatible with other existing and zoned uses for the Site and surrounding areas, and utilizes and improves an otherwise vacant parcel unlikely to be developed. No material adverse environmental effects are expected. A conditional use permit is respectfully requested for this environmentally beneficial facility.
