Transmission System Vegetation Management Program
Vegetation Management along the St Helens-Allston Transmission Line ROW. The line is a 115 kV Single Circuit Transmission Line having an easement width of 100 feet. BPA proposes to clear danger trees from varying widths of the indicated transmission line right-of-way that are approaching electrical clearance zones in accordance with the National Electrical Safety Code and BPA Standards. See Section 1.1 of the attached checklist for pertinent information on each section of referenced transmission line. BPA is clearing the danger trees to prevent them from falling or growing into the lines, thereby causing outages.
