Action
Final rule.
Summary
This final rule extends the existing excavation damage prevention requirements for gas pipelines in urban areas to gas pipelines in rural areas; establishes excavation damage prevention program requirements for hazardous liquid and carbon dioxide pipelines; requires, with limited exceptions, line markers for gas transmission lines in urban areas; and permits smaller lettering on line markers for hazardous liquid and carbon dioxide pipelines in heavily developed urban areas. This final rule is accompanied by a notice of proposed rulemaking (NPRM)(Docket No. PS-101A), which proposes mandatory participation in qualified one-call systems by pipeline operators. This final rule and the NPRM are intended to reduce excavation damage, the largest single cause of reportable pipeline accidents.
