On April 8, 2025, PHMSA revised their interpretation process to now include a 30-day period for pipeline operators and other stakeholders to review pending interpretation letters and submit their comments before final interpretation letters are released.
Additional information from the PHMSA page:
PHMSA makes available online each incoming interpretation request and allows for the submission of public comment. Before issuing a written interpretation, PHMSA will consider comments received on or before the comment closing date. Comments will not be responded to directly. Any comments received after the closing date will be considered if practicable.
For WinDOT Subscribers:
The pending interpretations will be linked directly into their designated code sections for convenience. They will be annotated with a "P" and a note at the top of the interpretations with instructions for submitting comments during the 30-day period.
