As a result of the inspection, PHMSA has identified an apparent inadequacy found within Columbia Gas’s plans or procedures. The item inspected and the inadequacy is described below: 1. § 191.5 Immediate notice of certain incidents. (a) At the earliest practicable moment following discovery, but no later than one hour after confirmed discovery, each operator must give notice in accordance with paragraph (b) of this section of each incident as defined in § 191.3. Columbia Gas’s written procedures for conducting operations and maintenance activities were inadequate to assure safe operation of a pipeline facility in accordance with § 191.5(a). Specifically, Columbia Gas’s LNG Operations and Maintenance (O&M): 191.05 Immediate Notice of Certain Incidents (US) (Rev. 4; 12/1/23), section 4.0, failed to specify that certain incidents must be immediately reported, no later than one hour after confirmed discovery, in accordance with § 191.5(a). Columbia Gas must revise its procedure to clarify that certain incidents must be immediately reported no later than one hour after confirmed discovery in accordance with § 191.5(a).#
