On August 14, 2019 (84 FR 41556) the Pipeline and Hazardous Materials Safety Administration (PHMSA) responded to numerous petitions for rulemaking submitted by the regulated community that requested PHMSA address a variety of provisions, including but not limited to those addressing packaging, hazardous communication, and incorporation by reference documents. PHMSA proposed amendments to the Hazardous Materials Regulations (HMR) to update, clarify, improve the safety of, or provide relief from various regulatory requirements. Some of the proposal include amending the hazardous materials regulations regarding: harmonizing the limited quantity exceptions for more than 100 entries, for corrosive materials, in the Hazardous Materials Table (HMT); revising the minimum height requirement of the proper shipping name marking on certain portable tanks; removing the reference to Special Provision of 103 in the hazmat table column 7 for four HMT entries; allowing for all waste materials to be managed in accordance with the lab pack exception and associated paragraphs in 49 CFR 173.12 irrespective of whether they meet the definition of a hazardous waste per the EPA or the RCRA; and revising the language in § 173.166 to clarify the term “recycle” by adding the word “metal” in front of “recycling. Comments must be submitted by October 15, 2019. To the extent possible, PHMSA will consider late-filed comments as a final rule is developed.
