Laws and regulations

When performing our vegetation management duties as required by law, we do our best to preserve the trees on your property. In some cases, however, problem trees or improperly planted trees pose too high a risk to public safety and electric system reliability and must be removed. If we don’t comply with regulations, we put the public at risk, increase the possibility of outages and face hefty fines.

What are the regulatory guidelines you follow?

PG&E is required to maintain minimum conductor-to-vegetation clearance distances around its high-voltage lines to comply with State and Federal regulations for public safety and electric service reliability. Transmission powerlines should only have low growing trees and shrub below them.

Standards A, B and C apply to distribution (high-voltage) and transmission (extremely high-voltage) lines.

Standard D applies only to transmission (extremely high-voltage) lines.
