NERC FAC-003-5 Vegetation Compliance
NERC FAC-003-5 requires documented Transmission Vegetation Management Programs with inspection schedules, clearance verification, and outage reporting. Violations can exceed $1 million per day. AcreSeal provides the forensic evidence chains and MVCD tracking your compliance program needs.
Minimum Vegetation Clearance Distances

AcreSeal NERC FAC-003-5 Capabilities
MVCD Clearance Tracking
Select the transmission line voltage class for any vegetation encroachment record. AcreSeal automatically compares the measured clearance distance against the NERC Minimum Vegetation Clearance Distance and flags records below threshold as 'NERC MVCD Violation — Immediate Action Required.'
Violation Auto-Flagging
When a clearance measurement falls below the MVCD for the applicable voltage class, AcreSeal generates a red-badge alert visible in the vegetation dashboard. This is an internal compliance flag — it does not auto-report to NERC, but ensures your team catches violations before they become audit findings.
Audit-Ready Evidence Export
Generate a NERC FAC-003-5 compliance report containing: utility name, reporting period, total transmission miles inspected, clearance violations with details, time to remediation, before/after photo verification with forensic hashes, and SHA-256 chain integrity attestation.
Forensic Chain Attestation
Every vegetation inspection, clearance measurement, and remediation record is sealed with SHA-256 hash chains. When a NERC Regional Entity (ReliabilityFirst, SERC, Texas RE) conducts a compliance audit, the evidence is verifiable at acreseal.com/verify.
