At the behest of Congress, coastal areas and beaches are now designated as Unusually Sensitive Areas (USAs). Given that any offshore liquids pipeline has the potential to affect coastal waters or beaches, the rule would seem to require that all such pipelines be included in Integrity Management Programs, which are mandatory for pipelines that could affect USAs. (The IMP requirements would almost certainly apply to all DOT regulated offshore pipelines. Their applicability to DOI/producer pipelines is less certain. Of course, very little is clear and consistent in US offshore pipeline regulation.)
As one would expect, the recent Huntington Beach pipeline spill is among the incidents cited in the justification for this regulation. More surprisingly, the Santa Barbara well blowout was also cited. This incident occurred 53 years ago, was the result of a reckless drilling program, and had nothing to do with production operations or pipelines.
As noted in a recent BOE post, the regulatory regime for offshore pipelines is badly in need of overhaul. DOT and DOI, with inconsistent jurisdictional boundaries, regulations, and approaches, have primary responsibility and multiple regulatory entities have roles.
Lastly, PHMSA seems to have inadvertently posted a highlighted copy of the new regulation. Nothing at all scandalous (looks like someone was highlighting potential talking points), but possibly amusing to other regulation nerds. 😃
