Notice of Proposed Rulemaking.
Summary
This notice proposes to allow operators of older hazardous liquid and carbon dioxide pipelines to elect a risk-based alternative in lieu of the existing rule. The existing rule requires the hydrostatic pressure testing of certain older pipelines. The risk-based alternative would allow operators to elect an approach to evaluating the integrity of these lines that takes into account individual risk factors. This would allow operators to focus resources on higher risk pipelines and effect a greater reduction in the overall risk from pipeline accidents.
