FOR Right-of-way contractors, pipeline operators and land-service firms
Specify the maintenance work along the corridor
Right-of-way maintenance can include mowing, tree work, erosion repair, access-road upkeep and other land services. The insurance description should distinguish those activities from excavation, pipeline repair or inspection. A contractor hired for vegetation work should not assume its existing classification includes every additional task requested by a field representative.
Identify the line type, access conditions, nearby structures, public crossings and sensitive land uses. Clarify who marks facilities, approves equipment movements and communicates restrictions. PHMSA’s integrity material identifies excavation and other external threats as relevant to pipeline risk; maintenance planning should therefore consider the operating asset beneath or beside the work area, not only the visible vegetation.
Review damage mechanisms unique to corridor work
Heavy equipment can damage access structures or concealed facilities; debris can strike vehicles or neighboring property; vegetation treatment may create drift or contamination allegations. Evaluate these scenarios separately when reviewing automobile, general liability, equipment and pollution arrangements. The fact that the work is described as maintenance does not make the exposure minor.
Examine underground-property restrictions, pesticide or herbicide exclusions where those materials are used, and obligations to restore land. Damage to the contractor’s own work and the cost of repeating unsatisfactory maintenance may be treated differently from injury or third-party property damage. Ask whether subcontracted tree crews or chemical applicators fall within the declared operation and contractual insurance structure.
Keep access obligations distinct from operating control
The pipeline operator generally retains responsibility for its system, while a land-service contractor controls its own equipment and employees. The agreement should define who authorizes entry, coordinates landowners and stops work when markings, terrain or conditions differ from expectations. An operator’s approval to enter a corridor is not proof that every activity there is insured.
Review indemnities, additional-insured requirements and responsibility for damaged gates, roads, drainage and crops. If a contractor also evaluates erosion or advises on remediation, consider whether that technical role requires professional liability review. A broad promise to keep the corridor safe may impose obligations beyond the specific maintenance services that the firm and its insurers contemplated.
Document the route and the work performed
Provide route types, equipment schedules, services, chemical use where applicable and representative contracts. Explain how crews receive facility information, record changes and escalate hazards. Include controls for public traffic, adjacent property and subcontractors, with attention to work performed far from the contractor’s permanent base.
After an allegation, preserve location records, photographs, daily work reports and instructions from the operator. A later pipeline or drainage problem may require evidence of exactly where the contractor worked and what equipment it used. Review completed-operations and reporting provisions rather than assuming liability ends when the crew leaves. Accurate scope and location records are especially valuable for recurring corridor contracts covering many sites.
Operational exposures & coverage review

| Buried facilities | Review equipment access and underground-property terms. |
| Vegetation treatment | Disclose chemicals, drift and applicator subcontractors. |
| Land restoration | Compare access promises with covered liability. |
Questions for your next review
- Does the contract include excavation or technical advice?
- Who approves equipment movement over the line?
- Can each crew’s work be tied to an exact location?
