PHMSA recently finalized a rule that significantly revises certain aspects of liquid pipeline safety regulation under 49 CFR Part 195.  Nearly nine years in the making, the final rule is intended to address PHMSA and NTSB accident investigation findings from the Marshall Michigan spill in 2010 as well as 2011 and 2016 outstanding Congressional mandates and GAO recommendations.  A version of this rule was initially scheduled for publication in the Federal Register in the last week of the prior presidential administration in 2017.  It was held back as a result of the regulatory freeze and subsequent deregulatory review by the Trump administration which pared down certain changes in the recent final rule.
