The project activities will be conducted along the Right-of-Way (ROW) of the Paul-Allston No 1 and 2 - 500 kV transmission line corridor between towers 45/4 and the Allston substation. This corridor includes portions of the Longview-Allston No 1 and 2 and the Longview-Allston No 3 and 4 - 230 kV transmission lines. The corridor along this section of the proposed project varies between 125 and 150 feet in width and crosses approximately 4 miles of terrain from Longview, Washington crossing the Columbia River and passing through rural forestland and pasture lands to the Allston Substation in Oregon. BPA proposes to remove unwanted vegetation along the right-of-way, along access roads and around tower structures along the subject transmission line corridor that may impede the operation and maintenance of the identified transmission lines. BPA plans to conduct vegetation control with the goal of removing tall growing vegetation that is currently or will soon be a hazard to the transmission line. BPA’s overall goal is to have low-growing plant communities along the rights-of-way to control the development of potentially threatening vegetation.
