On March 03, 2023 (88 FR 13624), the Pipeline and Hazardous Materials Safety Administration (PHMSA) published a Notice of Proposed Rulemaking (NPRM) in the Federal Register (FR) requesting public comment on proposed amendments to the Hazardous Materials Regulations (HMR) to update, clarify, improve the safety of, or streamline various regulatory requirements. 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 maintain or enhance the existing high level of safety under the HMR while providing clarity and appropriate regulatory flexibility in the transport of hazardous materials. Comments must be submitted by May 2, 2023. PHMSA will consider latefiled comments to the extent possible.
