EIS-0285-SA-118: Supplement Analysis

Transmission System Vegetation Management Program, Holcomb-Naselle 115kV, Pacific County, Washington

Vegetation Management along the Holcomb Naselle 115kV transmission line corridor from structure 1/1 through structure 21/10. BPA proposes to remove unwanted vegetation along the right-of- way, access roads and around tower structures along the subject transmission line corridor. Approximately 21 miles of right-of-way will be treated using selective and non-selective methods that include hand cutting, mowing and herbicide treatments. Approximately 1.0 miles of access road will be cleared using selective and non-selective methods that include hand cutting, mowing and herbicide treatments. Tower sites will be treated 30 feet from center of poles and or tower legs using selective and non-selective methods that include hand cutting, mowing and herbicide treatments. Vegetation management is required for unimpeded operation and maintenance of the subject transmission line. See Section 1of the attached checklist for a complete description of the proposal.
