During the months of March and April 2020 ComEd will begin performing regularly scheduled Transmission Corridor vegetation management activities within your area. ComEd’s vegetation management activities are necessary to ensure the reliability of electrical service and to ensure public safety.
As a public utility, ComEd has a legal obligation regarding the management of transmission corridors under both federal and state law. The mandatory Reliability Standard FAC-003-001 has been promulgated by the North American Electric Reliability Corporation (NERC), the Electric Reliability Organization certified by the Federal Energy Regulatory Commission (FERC) under the terms of the Federal Power Act. FERC has approved this Reliability Standard, which prescribes requirements for vegetation management programs in 83 III. Admin. Code 411.190, and the tariff approved by the Illinois Commerce (I.C.C. No. 10 at 152), also mandates compliance with the vegetation management requirements of the National Electric Safety Code.
The transmission corridors in your area are composed of large steel poles or tower structures that are used to transport large volumes of electricity. The transmission corridors are frequently located adjacent to interstate highways and railroad tracks. ComEd owns or has express property rights to perform vegetation management in the transmission corridor area.
Qualified line clearance workers contracted by ComEd perform all tree pruning and vegetation management work. Supervisors and general foreman maintain close contact with crews to ensure safety and adherence to proper vegetation maintenance procedures.
Trees and bushes that grow to heights less than 10 feet, may be approved by ComEd for planting near power lines. Trees that grow greater than 15 feet, for example maple, elm and blue spruce, should never be planted under or near power lines. At full height, these trees could contact lines and cause a power outage or create a safety issue.
