Pipeline Safety: Reporting Requirements for Exceedances of Maximum Allowable Operating Pressure

The Pipeline and Hazardous Materials Safety Administration (PHMSA) is issuing an advisory bulletin to inform pipeline owners and operators of their reporting obligations when the pipeline pressure exceeds the maximum allowable operating pressure (MAOP) plus the allowed build-up for pressure-limiting or control devices. The report must be submitted to PHMSA within five days of the exceedance, and in some cases, also to the applicable state agency.
