Route width variations outside the designated route may be allowed for the permittee to <br />overcome potential site specific constraints. These constraints may arise from any of the <br />following: <br />1) Unforeseen circumstances encountered during the detailed engineering and design <br />process. <br />2) Federal or state agency requirements. <br />3) Existing infrastructure within the transmission line route, including but not limited to <br />roadways, railroads, natural gas and liquid pipelines, high voltage electric transmission <br />lines, or sewer and water lines. <br />4) Planned infrastructure improvements identified by state agencies and local government <br />units (LGUs) and made part of the evidentiary record during the contested case <br />proceeding for this permit. <br />Any alignment modifications arising from these site specific constraints that would result in <br />right-of-way placement outside the designated route shall be located so as to have comparable <br />overall impacts relative to the factors in Minnesota Rule 7850.4100 as does the alignment <br />identified in this permit and shall also be specifically identified and documented in and approved <br />as part of the plan and profile submitted pursuant to Section 4.1 of this permit. <br />3.2 Right-of-Wav Placement <br />Where the transmission line route parallels existing highway and other road rights -of -way, the <br />transmission line right-of-way shall occupy and utilize the existing right-of-way to the maximum <br />extent possible, consistent with the criteria in Minnesota Rule 7850.4100, the other requirements <br />of this permit, and for highways under the jurisdiction of the Minnesota Department of <br />Transportation (Mn/DOT), Mn/DOT rules, policies, and procedures for accommodating utilities <br />in trunk highway rights -of -way. <br />3.3 Right-of-Wav Width <br />The 115 kV transmission line will be built primarily with single pole structures, which will <br />require a 75-foot right-of-way. Where the transmission line will be underbuilt with 2.7 miles of <br />existing distribution line along U.S. Highway 10, the project shall be designed to fit within the <br />existing distribution line easements, thereby reducing the amount of new right-of-way that would <br />be required. <br />November 2010 Page 1 9 <br />
