Mandatory Participation in Qualified One-Call Systems by Pipeline Operators

Notice of proposed rulemaking.

This notice proposes to require 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 proposed rule would also limit the current exclusion of certain small gas systems from compliance with the damage prevention program requirements. This notice is accompanied by a final rule (Docket No. PS-101), which addresses other requirements for excavation damage prevention programs and line markers. This notice and the final rule are intended to reduce excavation damage, the largest single cause of pipeline failures.
