When discussing standard clearances, the Commission stated: “Simply put, a "one-size-fits-all" approach is not appropriate. Furthermore, the record demonstrates that there already are nationally recognized industry standards and best practice vegetation management standards and practices for tree trimming which the Respondents follow. …The record also establishes that the adoption of a uniform statewide minimum clearance distance would increase costs and threaten reliability. … Line clearances should continue to take into consideration the characteristics of the locality, the electric facility and the health of the tree, along with the other pertinent factors identified by Respondents. However, it is imperative that the utilities actually consider and apply these factors in determining the appropriate clearance for a given tree or line. The record is replete with customer complaints that strong, healthy, mature trees were trimmed as aggressively as trees posing bigger risks to reliability. …If existing easements or rights of way are insufficient, utilities either need to obtain such additional easements as necessary from the property owner, or obtain the consent of the property owner prior to trimming vegetation outside of the easement or right of way. Second, as noted above, the ANSI standard leaves substantial judgment in the hands of the utility in determining how a tree will be trimmed. We find that if a tree would have more than 25% of its canopy removed, the utility must obtain consent from the property owner. If a property owner does not consent, and the owner and the utility are unable to mutually agree on how the tree can be trimmed to provide sufficient clearance in order to maintain reliable electric service, the utility shall consider removing the tree, at the utility's expense, as long as it has secured the requisite easements to allow its personnel onto the owner's property, or inform the customer that it will need to make non-ANSI standard cuts in order to provide clearance. 13 To the extent removal is required, the rulemaking discussed below in Paragraph 7(D) will also address a tree replacement program.” (pages 99-100)
