The Pipeline and Hazardous Materials Safety Administration (“PHMSA” or the “Agency”) published a Notice of Proposed Rulemaking (“NPRM” or the “Proposed Rule”) that provides increased flexibility to gas transmission pipelines that experience a certain change in population surrounding the pipeline (from a Class 1 to Class 3 location).

If finalized, the Proposed Rule would provide operators an alternative option to implement integrity management (“IM”) requirements to ensure that a pipe segment is subject to appropriate class location safety factors and thereby avoid unnecessary and costly pipe replacements or pressure reductions. Comments are due by December 14, 2020.
