The Pipeline and Hazardous Materials Safety Administration (PHMSA) is amending the Hazardous Materials Regulations in an effort to maintain alignment with international standards. Among other proposed changes, PHMSA plans to require manufacturers and “subsequent distributors” of lithium batteries to make available a Lithium Battery Test Summary (LBTS). The LBTS requirement is scheduled to go into effect January 1, 2020, but commenters have requested the agency to delay implementation until 2022, citing difficulties in meeting the 2020 deadline. Transportation providers are closely watching this rulemaking process to understand who may qualify as a “subsequent distributor” and how quickly the LBTS must be made available to those who request a copy in the final version of the rule.
