1 <br /> New structures will be designed to support the existing transmission and distribution <br /> ' lines,thereby allowing the use of existing alignments and will share existing road rights- <br /> of-way to the extent that such actions do not violate sound engineering principles or <br /> system reliability criteria. <br /> 1 Structures will be placed at the maximum feasible distance, consistent with sound <br /> engineering principles and system reliability criteria, from intersecting roads,highway,or <br /> trail crossings and could cross roads to minimize or avoid impacts. The Permittee shall <br /> work with landowners to identify and address issues related to the transmission line such <br /> as distance from existing structures,tree clearing, and other aesthetic concerns. <br /> 1 4.2.7 Erosion Control <br /> The Permittee shall follow standard erosion control measures outlined in Minnesota <br /> Pollution Control Agency (MPCA) guidance and best management practices regarding <br /> sediment control practice during constructi include protecting storm drain inlets,use of <br /> silt fences,protecting exposed soil, imm-,'a stabilizing restored soil, controlling <br /> ' temporary soil stockpiles, and contro g ice tracking. <br /> The Permittee shall implement re ''` abLwneasures to minimize runoff during <br /> ' construction and shall promptly pl s , erect silt ces, and/or use erosion control <br /> blankets in non-agricultural ea .. h e disturb wh a structures are installed. <br /> ' When utilizing seed to establish temporary a 1 permanent etative cover on exposed <br /> soil,the Permitte ill c. ` It with the Miwe Dep.- ment of Transportation <br /> (Mn/DOT)and M .nesot: I epartment of Natura a rces (MnDNR)to select site <br /> characterisfeleed" rt�ce• to be free of noxiousve-ds. <br /> Conto- w� ..e gred as req ' ed so that all surfaces drain naturally,blend with the <br /> ' natural :min, aeare left in a ondition that will facilitate re-vegetation,provide for <br /> proper drat and prevent erosion.

Minimal grading of areas <br /> around pole locations may be required to accommodate construction vehicles and <br /> ' equipment. <br /> t <br /> November 2010 Page j 11 <br /> I <br />
