Pub. Resources Code, § 4295.5

(a) Notwithstanding any other law, including Section 4295, a person who owns, controls, operates, or maintains an electrical transmission or distribution line may traverse land as necessary, regardless of land ownership or express permission to traverse land from the landowner, after providing notice and an opportunity to be heard to the landowner, to prune trees to maintain clearances pursuant to Section 4293, and to abate, by pruning or removal, any hazardous, dead, rotten, diseased, or structurally defective live trees. The clearances obtained when the pruning is performed shall be at the full discretion of the person that owns, controls, operates, or maintains any electrical transmission or distribution line, but shall be no less than what is required in Section 4293. This section shall apply to both high fire threat districts, as determined by the California Public Utilities Commission pursuant to its rulemaking authority, and to state responsibility areas.

(b) Subdivision (a) does not exempt a person who owns, controls, operates, or maintains an electrical transmission or distribution line from liability for damages for the removal of vegetation that is not covered by an easement granted to the person for the electrical transmission or distribution line.
