Supplement Analysis for the Transmission System Vegetation Management Program FEIS (DOE/EIS-0285/SA-151-Big Eddy-Ostrander 1)

Removal of danger trees along the Big Eddy-Ostrander-1 transmission line corridor. This corridor also includes segments of the Big Eddy-Troutdale, Ostrander-Troutdale, Big Eddy-McLoughlin and Bid Eddy-Chemawa transmission lines. Referencing the Big-Eddy-Ostrander-1 transmission line, the project extends from tower 39/3 to 72/2. The portion of the ROW extending from 39/3 west to 44/5+313 falls within the Zigzag Ranger District of the Mt. Hood National Forest, Clackamas County, Oregon. All work conducted within the Mt. Hood National Forest has been previously addressed in the Supplement Analysis for the Transmission System Vegetation Management Program (DOE/EIS-0285/SA-113-1) dated 12/02/2002 and will conform to the requirements therein. This Supplement Analysis evaluates that portion of the project proposed for the remainder of the transmission line corridor extending from 44/5+313 west to 72/2. BPA proposes to manually remove danger trees located along the indicated transmission line rights-of-ways that are approaching electrical clearance zones defined in accordance with the National Electrical Safety Code and BPA Standards. Manual removal involves chainsaws, brush cutters, or hand tools. BPA would then treat the associated hardwood stumps with herbicides using spot and localized treatments to ensure that the roots are killed and to prevent new sprouts. Spot treatments and localized treatments consist of direct applications of herbicide to an individual target plant or small group of plants using minimal amounts of herbicide. See Section 1.1 of the attached checklist for pertinent information on each section of referenced transmission line included in the proposal.
