Rule
Summary
This final rule amends the hazardous materials program procedures to allow motor and vessel carriers to carry PHMSA registration documents in electronic form.
Analyzed Economic Effects
4 provisions identified: 2 benefits, 2 costs, 0 mixed.
Carry Hazmat Registration Electronically
If you are a motor or vessel carrier, you may carry your PHMSA Certificate of Registration or a document showing your registration number in electronic form or on paper starting September 3, 2026. The regulation change amends 49 CFR 107.620 and allows the document labeled the "U.S. DOT Hazmat Reg. No." to be electronic.
Three-Year Record Retention Rule
If you are subject to this rule, you must keep at your principal place of business a copy of the PHMSA registration statement and the Certificate of Registration for three years from the date the Certificate is issued. These records may be kept in electronic or paper form.
Must Provide Documents to Inspectors
If you transport hazardous materials, you must make your Certificate of Registration and related records available to authorized enforcement or inspection personnel upon request, whether those documents are electronic or on paper. This availability requirement is effective September 3, 2026.
Applies to Trucks and Tractors, Not Trailers
For motor carriers, the rule requires carrying the current Certificate of Registration or a document showing the registration number on each truck and truck tractor (but not on trailers or semi-trailers) used to transport hazardous materials; the document may be electronic or paper.

PHMSA fixed a small but important detail in a new pipeline safety rule from January 2026. Pipeline operators can now confirm or restore safe pressure levels when neighborhoods change around their pipes, with a clear 24-month deadline starting either from the rule’s effective date or when they begin work. This helps keep gas pipelines safe without confusion about timing, so operators know exactly when to act and avoid costly delays.

Pipeline companies and safety pros, listen up! PHMSA just said no to changes requested by the Interstate Natural Gas Association about pipeline safety rules for areas where people live or work.
