Pipeline Safety Alert
(by James Curry, Keith Coyle and Brianne Kurdock)
This is the last alert in a four-part Babst Calland series on PHMSA’s final rule amending the gas pipeline safety regulations at 49 C.F.R. Part 192 (Rule), published in the Federal Register on October 1, 2019. The first alert reviewed new requirements for materials verification and reconfirmation of maximum allowable operating pressure (MAOP). The second alert discussed PHMSA’s extension of integrity assessment requirements to areas outside high consequence areas (HCAs). The third alert reviewed the new recordkeeping requirements. This alert discusses the remaining rule topics: strengthening assessment requirements, extending the integrity management (IM) reassessment schedule, adding safety features to launchers and receivers, evaluating seismicity, and reporting MAOP exceedances.
Strengthening Assessment Requirements
PHMSA has incorporated a series of industry consensus standards regarding the use of in-line inspection (ILI) tools for pipeline assessments. PHMSA has also expanded the array of assessment methods that operators may use, both for covered segments in HCAs and in non-HCA areas.
What’s in the Rule?
- Incorporation by reference of NACE SP0102-2010, Inline Inspection of Pipelines, which relates to the design and construction of pipeline facilities to accommodate the passage of ILI devices, as well as the performance of ILI assessments (§§ 192.150 and 192.493). Operators may use tethered or remotely controlled tools not explicitly noted in NACE SP0102, as long as they comply with the sections of that standard that are applicable given the technology.
- Incorporation by reference of API STD 1163, In-Line Inspection Systems Qualification Standard, which sets out performance-based requirements for ILI procedures, personnel, equipment and software and ANSI/ASNT ILI-PQ, In-Line Inspection Personnel Qualification and Certification (§ 192.493).
