Safety of Hazardous Liquid Pipelines Rule

Policy March 07, 2016

AGA submitted comments on PHMSA’s draft Hazardous Liquid Pipeline Integrity Verification Process chart. The comments reiterated many of the concerns that were outlined by AGA’s four previous sets of comments submitted on the Gas Transmission Pipeline IVP chart. Those areas include: separation of MAOP verification from expansion of integrity management, delineation of low stress pipelines at 30 percent SMYS, and the ambiguous introduction of new terms such as moderate consequence areas, engineering critical assessments and spike testing.
