(1) An electric utility is immune from liability under RCW 64.12.030, 64.12.040, and 4.24.630 and any claims for general or special damages, including claims of emotional distress, for cutting or removing vegetation located on or originating from land or property adjacent to electric facilities that:

(a) Has come in contact with or caused damage to electric facilities;

(b) Poses an imminent hazard to the general public health, safety, or welfare and the electric utility provides notice and makes a reasonable effort to obtain an agreement from the resident or property owner present on the property to trim or remove such hazard. For purposes of this subsection (1)(b), notice may be provided by posting a notice or flier in a conspicuous location on the affected property that gives a good faith estimate of the time frame in which the electric utility's trimming or removal work must occur, specifies how the electric utility may be contacted, and explains the responsibility of the resident or property owner to respond pursuant to the requirements of the notice. An electric utility may act without agreement if the resident or property owner fails to respond pursuant to the requirements of the notice. No notice or agreement is necessary if the electric utility's action is necessary to protect life, property, or restore electric service; or

(c) Poses a potential threat to damage electric facilities and the electric utility attempts written notice by mail to the last known address of record indicating the intent to act or remove vegetation and secures agreement from the affected property owner of record for the cutting, removing, and disposition of the vegetation. Such notice shall include a brief statement of the need and nature of the work intended that will impact the owner's property or vegetation, a good faith estimate of the time frame in which such work will occur, and how the utility can be contacted regarding the cutting or removal of vegetation. If the affected property owner fails to respond to a notice from the electric utility within two weeks of the date the electric utility provided notice, the electric utility may secure agreement from a resident of the affected property for the cutting, removing, and disposition of vegetation.

(2)(a) A hazard to the general public health, safety, or welfare is deemed to exist when:

(i) Vegetation has encroached upon electric facilities by overhanging or growing in such close proximity to overhead electric facilities that it constitutes an electrical hazard under applicable electrical construction codes or state and federal health and safety regulations governing persons who are employed or retained by, or on behalf of, an electric utility to construct, maintain, inspect, and repair electric facilities or to trim or remove vegetation; or

(ii) Vegetation is visibly diseased, dead, or dying and has been determined by a qualified forester or certified arborist employed or retained by, or on behalf of, an electric utility to be of such proximity to electric facilities that trimming or removal of the vegetation is necessary to avoid contact between the vegetation and electric facilities.

(b) The factors to be considered in determining the extent of trimming required to remove a hazard to the general public health, safety, or welfare may include normal tree growth, the combined movement of trees and conductors under adverse weather conditions, voltage, and sagging of conductors at elevated temperatures.

(3) A potential threat to damage electric facilities exists when vegetation is of such size, condition, and proximity to electric facilities that it can be reasonably expected to cause damage to electric facilities and, based upon this standard, the vegetation has been determined to pose a potential threat by a qualified forester or certified arborist employed or retained by or on behalf of an electric utility.
