Enterprise Park to Crooked Lake 115 kV Transmission Line March 2012 Environmental Assessment any EMI present, proper GPS function is usually restored in minutes (IEEE, 2002 as cited in Minnkota Power Cooperative, Inc., n.d.). Cell phones and wireless internet devices operate at an ultra -high frequency (UHF). In general, as frequency increases, radio frequency noise decreases. Radio frequency noise is generally not existent in the UHF range. High voltage transmission lines are not known to cause interference in cellular phone and wireless internet function. Mitigation - Interference with Utility Systems and Public Services The Project would be constructed to comply with NESC standards. No large scale adverse effects of the Project on utility systems are expected. If radio or television interference occurs because of the transmission line, the Applicant will work with the affected landowner to mitigate the problems so that reception is restored. If television or radio interference is caused by or from the operation of the proposed facilities in those areas where good reception is presently obtained, The Applicant will inspect and repair any loose or damaged hardware in the transmission line, or take other necessary action to restore reception to the pre -Project level, including the appropriate modification of receiving antenna systems if necessary. Any planned service disruptions to electric utility services that are necessary during construction activities would be scheduled with the affected owners of the existing transmission and distribution lines in accordance with reliability standards. Advanced scheduling of these disruptions would allow for alternative arrangements for electrical service to be made when possible and to allow for customers to be notified in advance. Utility repair crews would be present or on -call during construction activities to respond to any unplanned incidents that may result in an interruption to electric service. 5.1.5. Archaeological and Historic Resources One recorded historical site was identified within the Proposed Route. Although additional sites have been recorded within one mile of the Proposed Route, the Project will have negligible impacts on these sites, and then only from a visual perspective The Minnesota Historical Society (MHS) was contacted requesting information on the possible effects of the proposed Project on historic properties in the Project area. MHS indicated that the proposed Project was reviewed pursuant to the responsibilities given the State Historic Preservation Officer by the Minnesota Historic Sites Act and the Minnesota Field Archaeology Act. The Applicant contracted an archeological literature review of the project area. Fourteen previously recorded archaeological sites exist within one mile of the Project. Only one of the 14 sites is located directly in the Proposed Route. The previously recorded site within the Proposed Route is located in the vicinity of River Bend Park. The site was identified in 1989 during a survey of the entire island on which the park is established. The site was deemed to be non -eligible for registration on the National Register of Historic Properties, and it was subsequently filled over during 31
