Pipeline Safety: Harmonize Class Location Change Pressure Test Requirements with Subpart J Pressure Test Requirements

The Interstate Natural Gas Association of America (INGAA) supports the proposed rule to harmonize pressure test durations for class location changes with Subpart J requirements. They argue that the four-hour duration is technically sufficient for safety and provides much-needed regulatory clarity for pipeline operators.

Air Liquide Large Industries US, L.P. opposes the proposed rule because it expands the use of a four-hour pressure test without mileage limits and suggests reducing testing duration in areas where pipeline risk increases due to population growth. The company argues that the proposal removes historical safety safeguards and requests that the agency reconsider the rule or at least impose mileage limits.

The Pipeline Safety Trust is requesting an extension of the comment period for the proposed action to allow for a more substantive and deliberate review. They argue that the volume of recent rulemaking notices requires more time to consult with experts and stakeholders.

The commenter is asking for specific definitions and clarifications regarding what constitutes a "short segment" of pipe and what qualifies as "impractical" to conduct an 8-hour pressure test. They are requesting that PHMSA define these parameters and explain why tests cannot be conducted in nearby fabrication yards before installation.

The commenter supports the proposed update to allow code-compliant 4-hour pressure tests but requests clarification on the definition of a "short section of pipe" and the specific inspection requirements for such sections.
