Safety of Gas Transmission & Gathering Lines Rule

Policy September 20, 2018

On August 25, 2011, PHMSA published an Advance Notice of Proposed Rulemaking to seek feedback and comments regarding the revision of the Pipeline Safety Regulations applicable to the safety of gas transmission and gas gathering pipelines. On April 8, 2016, PHMSA published a Notice of Proposed Rulemaking which addressed Congressional mandates from the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 (Pipeline Safety Act), as well as recommendations from the National Transportation Safety Board (NTSB). During the last Gas Pipeline Advocacy Committee meeting, held in March 2018, PHMSA announced it would be divide the rulemaking into three separate rulemakings.

The first rulemaking will focus on Congressional Mandates, such as MAOP verification, records, material verification and assessments of pipelines outside of High Consequence Areas (HCAs). The second rulemaking will focus on all additional topics outside of the scope of the Congressional Mandate, such as fracture mechanics, anomaly response, repair criteria for HCA and non-HCA pipe segment, cathodic protection, and management of change. Finally, the third rule will address gas gathering lines.  

AGA, INGAA, API, and APGA filed comments and redlined changes on the first and the second rulemakings in May 2018 and June 2018, respectively. In 2019, PHMSA will hold a GPAC meeting to discuss the gathering lines rulemaking.

All three rules are anticipated to be published by the end of 2019.
