Hazardous Materials: Adoption of Miscellaneous Petitions and Updating Regulatory Requirements

The Pipeline and Hazardous Materials Safety Administration's (PHMSA) Hazardous Materials Regulations (HMR) are being updated, clarified, made safer, or simplified through the use of a Notice of Proposed Rulemaking (NPRM).

Specifically, this rulemaking responds to 18 petitions for rulemaking submitted by the regulated community between May 2018 and October 2020 that requests PHMSA address a variety of provisions, including but not limited to those addressing packaging, hazard communication, and the incorporation by reference of certain documents.
These proposed revisions keep or improve the HMR's current high standard of safety while providing clarity and appropriate regulatory flexibility in the transport of hazardous materials.
