Transmission System Vegetation Management Program

Vegetation Management around wood poles in Transmission Line ROW’s in the Walla Walla Region. BPA proposes to clear unwanted vegetation around wood poles and switch platforms. The vegetation clearing around wood poles is for fire protection. Over the last 3 years, BPA has been able to increase reliability and reduce losses due to rangeland fires by applying a soil residual herbicide as a wood pole fire treatment around wood pole structures which provide a 10 to 15 foot vegetation free area at our structure sites.
