Can I hire my own tree contactor to trim trees within 10’ of an electrical conductor?
• There are state and federal laws that regulate tree maintenance. Avista does not interpret these laws for our customers or private contractors. • Laws and regulations include ANSI Z133.1, OSHA 1910, WAC 296-45 and Idaho’s Overhead Line Safety Act. • Avista enters into formal agreements with contractors to trim trees and clear rights of way corridors throughout our service territory to ensure the safety, reliability and integrity of our electric and high pressure gas pipeline facilities.
