Enterprise Park to Crooked Lake 115 kV Transmission Line March 2012 Environmental Assessment every two miles along the project route. The conductors are pulled with a rope lead that connects to every structure through a dolly attached at the insulator location. Temporary guard or clearance poles are installed at crossings to provide adequate clearance over other utilities, streets, roads, highways, railroads, or other obstructions after any necessary notifications are made or permit requirements met to mitigate any concerns with traffic flow or operations of other utilities. In lowland areas, construction activities may occur during the winter season to mitigate any damage to wetland areas or other sensitive areas, or to comply with required crossing permits. A pre -construction meeting with the State of Minnesota will outline any special requirements for the contractor prior to the start of any construction activities. During construction, when temporary removal or relocation of fences needs to occur, installation of temporary or permanent gates may be required. The Applicant will be required via the route permit to coordinate with the landowners on replacement of fences and gates. Regardless of the route or technique selected, similar construction equipment would be required. Equipment that would be used for construction includes: tree removal equipment, mowers, cranes, backhoes, digger -derrick line trucks, track -mounted drill rigs, dump trucks, front end loaders, bucket trucks, bulldozers, flatbed tractor -trailers, flatbed trucks, pickup trucks, concrete trucks, and various trailers. Modifications to the Enterprise Park and Crooked Lake 115-kV substations will begin once permits are received and the final design is complete. A detailed construction schedule will be developed based upon availability of crews, outage restrictions for any transmission lines that may be affected, weather conditions, spring load restrictions on roads, and any restrictions placed on certain areas for minimizing impacts from construction. The Applicant has stated that all construction will be completed in accordance with state, NESC, Great River Energy, Anoka Municipal Utility and Xcel Energy construction standards regarding clearance to ground, clearance to crossing utilities, clearance to buildings, right-of-way widths, erection of power poles (to connect the line to the substation), and stringing of transmission line conductors. Less than one acre of land is expected to be disturbed in the modifications of each substation. Some grading of the substations will be needed followed by pouring concrete foundations to support the substation equipment and control house. 4.1. Property/Right-of-Way Acquisition There are approximately 4.4 miles of existing overhead electric distribution lines located within the 5.8-mile proposed route. These existing distribution lines are owned, operated and maintained by Anoka Municipal Utility. In most instances, there will likely be some element of physical conflict with the new transmission line, making it necessary to 14
