v <br /> Xcel Energy <br /> 414 Nicollet Mall <br /> RESPONSIBLE BY NATURE"' Minneapolis, Minnesota 55401-1993 <br /> February 7,2013 <br /> VIA ELECTRONIC FILING <br /> Dr. Burl W. Haar <br /> Executive Secretary <br /> Minnesota Public Utilities Commission <br /> 350 Metro Square Building <br /> 121 Seventh Place East <br /> St. Paul,MN 55101 <br /> Re: Updated Plan and Profile for Orono Substation Replacement and New 115 kV <br /> Transmission Line Project <br /> Docket No. E002/TL-11-223 <br /> Dear Dr. Haar: <br /> Northern States Power Company (Xcel Energy), a Minnesota Corporation, obtained a route <br /> permit(dated April 6, 2012)to construct approximately 0.4 miles of new double circuit 115 kV <br /> overhead electric transmission line, relocate approximately 0.2 miles of Xcel Energy's existing <br /> 115 kV transmission line 0831, and replace Xcel Energy's existing Orono Substation in the City <br /> of Orono, Hennepin County, Minnesota. Section 4.1 of the route permit requires that Xcel <br /> Energy submit to the Commission the plan and profile and specifications for right-of-way <br /> (ROW)preparation and restoration of the transmission line. <br /> Plan and profile drawings were submitted on January 18, 2012. DOC EFP staff contacted Xcel <br /> Energy regarding that filing and posted a Permit Compliance Filing Review to the docket earlier <br /> today indicating that the filing is incomplete and identified five items which required more detail <br /> or were missing from the original filing. This letter and enclosed updated plan and profile <br /> drawings address those issues identified in the EFP review. <br /> 1. Right-of-way preparation and restoration. Construction crews plan to access the ROW from <br /> Xcel Energy's Orono Substation Property. Preparation for construction of the line will include <br /> construction of a temporary ramp from the substation pad to reduce the angle of the slope for vehicles <br /> entering the ROW from the south. Poly mats will be installed on top of the ramp and along the access <br /> route to each structure location to allow tree clearing and construction equipment access without <br /> disturbing wetland soils. Construction pad areas will be matted around each structure location. <br /> Equipment will work from these mats for the duration of the project. When construction is completed <br /> the mats and temporary access ramp will be removed. The area under the ramp will be re-graded if <br /> needed and re-seeded with a wetland buffer seed mix which has been approved by the Minnehaha <br /> Creek Watershed District(MCWD). <br />
