**Type / status:** rulemaking / historical

This final rule requires that operators of onshore gas, hazardous liquid, and carbon dioxide pipelines participate in qualified one-call systems as part of the required excavation damage prevention programs. The rule also limits the current exclusion of certain small gas systems from compliance with the damage prevention program requirements. This final rule is intended to reduce excavation damage, the largest single cause of pipeline failures.
