SUMMARY: PHMSA is issuing an Advisory Bulletin to provide clarification to owners and operators of gas distribution pipeline facilities when completing the Mechanical Fitting Failure Report Form, PHMSA F 7100.1-2. Initial reviews of reports submitted for calendar year 2011 failures have identified a need for PHMSA to issue this notice to provide operators with additional guidance for reporting the apparent cause. PHMSA has also enhanced the online submittal process and plans to implement further improvements.
