Steps
Confirm which FAC-003 version (currently FAC-003-4/5) and voltage threshold applies to the specific transmission line (historically ≥200kV, though a 2026 NERC wildfire report proposed extending coverage down to 100kV)
Obtain the utility's current vegetation management plan and minimum clearance distances for the specific line/right-of-way being cleared
Clear/trim vegetation to maintain the specified minimum clearance at all times, not just at the time of the scheduled maintenance cycle
Document completed work against the utility's vegetation management plan for their FAC-003 compliance recordkeeping, since NERC audits are based on utility-maintained records
Coordinate with the utility on any shift from fixed calendar-based trim cycles toward risk-based, data-driven prioritization, an approach gaining traction in 2026 guidance
Known gotchas
FAC-003 is a reliability standard the utility (not the contractor directly) is accountable to NERC/FERC for - the contractor's documentation obligations flow from the utility's compliance program, not directly from NERC
Proposed expansion of FAC-003 down to 100kV facilities was still a proposal as of the 2026 report, not yet an adopted requirement - don't represent it as already in force
Landowner/easement rights for tree removal along transmission ROWs are governed by the specific easement language, which can be more or less permissive than the reliability standard's minimum clearance
