All crew foremen are certified line clearance tree trimmers, and all general foremen are arborists certified by the International Society of Arboriculture. All crew foremen with the tree trimming contractors working for Ameren Illinois have a valid company identification badge.

Brush/Debris Removal

  • When a crew is trimming for regular maintenance, the brush debris is normally chipped and any logs are left on site for customer use.   


  • When trees and branches are cleared from power lines due to storm damage or natural weaknesses, emergency crews will not clean up the debris but will leave it for disposal by the property owner.


  • If a homeowner is contracting a private tree service to trim or remove a tree, Ameren Illinois will assist in making the tree safe for a qualified tree service to do their work. The debris will be left for the homeowner’s tree service to remove.

Free Wood Chips

Wood chips are generated from trees that have been trimmed. These wood chips are available to customers, and can be delivered at your request when tree crews are in your area.

Only full loads are available and average about 10-12 yards per load. These wood chips consist of multiple tree species, are irregular in shape and color, and can include some twigs and rakings. For more information, call Ameren Illinois at 800.755.5000.
