Enterprise Park to Crooked Lake 115 kV Transmission Line March 2012 Environmental Assessment 3. Proposed Project The proposed Project is for the construction of approximately 5.8 miles of new, overhead 115 kV transmission line between Xcel Energy's existing Crooked Lake Substation in Coon Rapids, Minn., and Anoka Municipal Utility's existing Enterprise Park Substation in Anoka, Minn., in Anoka County (Figure 2). The project will remove, rebuild, and attach Anoka Municipal Utility's existing overhead (12.5 kV) distribution lines to the new 115 kV transmission line where the new line overtakes the existing distribution lines. (Alternatively, Anoka Municipal Utility may choose to bury some of the distribution lines.) The project would also include modifications to the existing Crooked Lake and Enterprise Park substations. The Applicant is requesting a route width as narrow as 100 feet in some locations, and as wide as 400 feet in others, except for the area near Anoka High School where the requested route width is 800 feet. The variation in route width is due to the developed nature of the project area. The typical right-of-way for the 115 kV line is 50-75 feet, depending on the structure used. The typical span between poles without underbuild is 300 to 400 feet, and 250 to 300 where 12.5 kV distribution lines are attached. Poles range in height from 60 to 85 feet. Most poles will be constructed as single -pole, wood structures with horizontal post insulators. The transmission line and substation modifications would cost approximately $11.7 million. Modifications to the existing Crooked Lake and Enterprise Park substations would consist of a new ring bus, breaker additions, step down transformers, and associated switch gear. The substation yards will be expanded by less than one acre to accommodate the added equipment. Upon issuance of a route permit by the Commission, the Applicant would begin ROW acquisition. Construction of the Project is expected to begin in May, 2013. The estimated in-service date of the Project is October, 2013. 3.1. Purpose of the Project The stated need of the Project is to address conductor overload concerns to consumers in the Highway 10 corridor from Anoka to Elk River, create a redundant transmission source to the Enterprise Park Substation, providing a more reliable energy source to the industrial loads in the area, support local economic development efforts by the cities of Anoka and Ramsey, provide a transmission line for a future Anoka Municipal Utility substation in the vicinity of 7th Avenue and County Road 116, and to facilitate longer - term opportunities to further strengthen the power supply service to the area. 3.2. Project Location The proposed Project would be located primarily in the city of Anoka, Anoka County, Minnesota. The proposed transmission line will pass through small portions of the cities of Coon Rapids and Ramsey, Anoka County, Minnesota (Figure 2.) Table 3.1 identifies the geographic areas spanned by the project. Detailed Map Sheets of the Project route are found in Appendix A to this EA. 8
