🔧Proposed Rule on Pipeline Safety Compliance by PHMSA
Pipeline Safety: Harmonize Class Location Change Pressure Test Requirements With Subpart J Pressure Test Requirements
Summary
PHMSA is proposing to revise the regulation for confirming or revising the maximum allowable operating pressure following a class location change to clarify that owners and operators of gas pipeline facilities can use to satisfy that requirement certain pressure tests authorized by subpart J of part 192 for small segments of pipe.

The proposed rule from PHMSA alters compliance requirements for gas pipeline owners, allowing them to use a 4-hour pressure test to confirm maximum allowable operating pressure (MAOP) after a class location change rather than an 8-hour test. This change reduces regulatory burdens and costs, directly affecting business operations in the pipeline sector.
