Regulations, Standards, and Compliance
This domain tests the regulatory frame around UVM. You must know which rules apply to transmission versus distribution, what standards govern pruning, and when environmental laws add constraints.
Core rules and concepts
- NERC FAC-003 requires a documented transmission vegetation management program, annual inspection, maintenance of minimum vegetation clearance distances (MVCD), and reporting of vegetation-caused outages within its scope. It is not a distribution standard.
- ANSI A300 Part 1 (Pruning) and Part 7 (Integrated Vegetation Management) are consensus standards; they define practices but do not replace law or utility specifications.
- OSHA 1910.269 addresses electrical safety and line-clearance tree trimming; ANSI Z133 covers arboricultural operations safety.
- Environmental rules can include the Endangered Species Act, Migratory Bird Treaty Act, Clean Water Act, pesticide label requirements, and state or local permits.
- Keep inspection, clearance, training, application, and notification records that show compliance.
Worked example
A transmission span crosses a wetland and a heron rookery. Before work, check FAC-003 scope and MVCD, screen for listed species and nesting birds, obtain any wetland permit, and schedule outside the nesting window or use a nest survey. Document the decision.
Traps that cost marks
Applying FAC-003 to distribution; treating ANSI A300 as optional or as law; assuming the MBTA applies only on federal land; and ignoring state rules that are stricter than federal rules.
