Tree trimming meets the American National Standards Institute A300 standard. This is a generally accepted industry standard for tree care.
Before trimming trees near a residence, the contractor attempts to contact the member by knocking on the door. If no one answers, they leave a door hanger letting them know the maintenance occurred. TCEC has a right and a responsibility to trim trees in its rights-of-way to keep your power safe and reliable.
If there are any questions please contact TCEC 580.652.2418.
