Pipeline Safety Alert
(by Keith Coyle, Chris Hoidal and Brianne Kurdock)
On August 24, 2022, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published a new final rule for onshore gas transmission pipelines (the Rule). The Rule marks the completion of a three-phase rulemaking process, commonly referred to as the Gas Mega Rule, that began more than a decade ago. While this part of the Gas Mega Rule is commonly known as the “Repair Rule,” there are numerous other safety provisions that are included in the new regulation that should not be overlooked. The Rule amends or adds various provisions in 49 C.F.R. Part 192 and will become effective on May 24, 2023.
In the Rule, PHMSA added, clarified, or modified the following sections of the natural gas pipeline safety regulations:
- definitions in section 192.3;
- the management of change process;
- corrosion control requirements;
- inspections of pipelines following extreme weather events;
- integrity management provisions;
- integrity management assessment requirements;
- revised repair criteria in high-consequence areas; and
- new repair criteria for non-high consequence areas.
Definitions and Standards Incorporated by Reference
PHMSA added new definitions referenced in the new regulations, including close interval survey, distribution center, dry gas or dry natural gas, hard spot, in-line inspection (ILI), in-line inspection tool or instrumented internal inspection device, and wrinkle bend. Furthermore, the definition of transmission pipelines was revised to include a “connected series” of pipelines to clarify that transmission pipeline can be downstream of other transmission pipelines, and to allow operators to voluntarily designate their pipelines as transmission lines. …
