Pruning Standards

 Pruning Standards 

BGE’s Tree and Vegetation Management Program is here to protect power lines from coming into conflict with the tress and branches. For preventive maintenance, BGE follows accepted utility clearance standards outlined in Maryland’s Tree Expert License Law and the A300 standards for pruning established by the American National Standards Institute.
BGE uses only licensed utility-qualified professional tree-trimming contractors to manage the trees and plants around our power lines and equipment.
Maryland Standards
The Maryland Public Service Commission (PSC) has developed new regulations (RM 43) to govern how Maryland utilities manage their reliability efforts. BGE implements these regulations and customers can expect the following from our Tree and Vegetation Management Program:
  • Additional pruning or removal of trees
  • More comprehensive tree and vegetation management along lines located close to the company’s electrical substations – important facilities that manage delivery of power to customer homes.


When a neighborhood is scheduled for tree and vegetation management work, our contractors place door hangers to let property owners know when to expect our crews. If heavy tree pruning or removal is required, you will be contacted directly. If you have questions about the proposed work, call our contractor directly, using the phone number on the door hanger.


  • The clearance required for a power line depends on the voltage and construction of the line, the growth rate and species of the tree, and the tree’s proximity to the line.
  • Our contractors leave as much of the remaining tree crown growing away from the lines as possible, which maintains tree health.
  • If a large portion of the tree crown is removed, removal of a tree may be recommended.
  • If a hazardous tree is identified, we work with the property owner to ensure that the tree is properly managed to minimize the risk to the BGE lines.

Final cuts are determined by the structure of the individual tree limb, not by distance. Final cuts are made at lateral branches large enough to maintain the health of the remaining limb, or to the trunk of the tree.


  • In urban/residential areas, all cut branches less than eight inches in diameter are removed (typically shredded in wood chippers) and the remaining wood is cut to manageable lengths and left for the property owner’s use.
  • In rural wooded areas, the debris is cut close to the ground to encourage natural decay.
  • BGE does not take requests for wood chips. If you would like wood chips from tree trimming in your area, please contact the contractor listed on your notification door hanger to check on availability.
  • If a tree on your property breaks or falls on our equipment, BGE does not remove the debris.
