Citing concerns that intrastate and small gas transmission pipeline operators may not be accurately identifying high consequence areas (HCAs) as part of their integrity management programs (IMP), PHMSA issued yet another advisory to the industry on December 12, 2016. In its seventh advisory issued this year, PHMSA explains the need for further guidance on the methodology based on recent inspections as well as a Safety Recommendation issued by the National Transportation Safety Board (NTSB) in 2015 (NTSB Recommendation P-15-06, issued in conjunction with the Board’s Safety Study of implementation of gas transmission integrity management rules).
Over the past several years PHMSA has issued numerous Advisories and Guidance notices. In fact, the Agency has issued nine times more informal guidance documents than formal rulemakings on pipeline safety issues since January 2012 (6 Notices or Advanced Notices of Proposed Rulemakings, compared to 54 interpretative letters, advisories or guidance). The Pipeline Safety Act comes up for reauthorization next year, and as of this post the Agency has still not proposed rules on four issues that Congress expressly directed PHMSA to address in 2012 (excluding an additional six issues that Congress gave PHMSA the discretion to issue regulations “if appropriate” or “as necessary”). To date, PHMSA has only issued one final rule as a result of the 2011 Pipeline Safety Act Reauthorization (which became effective January 2012).
