In this final rule, PHMSA is making certain editorial corrections and non-substantive changes to the accident reporting requirements for hazardous liquid and carbon dioxide pipeline facilities in the Federal Pipeline Safety Regulations (49 CFR parts 190-199). Specifically,?195.52 requires operators of hazardous liquid and carbon dioxide pipeline facilities to provide immediate notice of certain accidents to the National Response Center (NRC) either by telephone or electronically. The NRC no longer allows operators to provide electronic incident notifications. PHMSA is therefore revising?195.52(b) to remove all references to electronic NRC submissions. Operators must provide notices of accidents to the NRC by telephone to 800-424-8802 or, in Washington, DC, 202-267-2675. This correction will remove unnecessary delays in the process of operators reporting accidents to the NRC. This rule is effective 3 August 2026.
