The Coast Guard announced in the Federal Register that it is aligning liquid chemical categorization tables in its tank vessels and bulk dangerous cargo regulations with the 2020 Edition of the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk and the International Maritime Organization’s 2019 Marine Environment Protection Committee’s Circular 25.
The Coast Guard is issuing these updates because the updated tables provide a list of the liquid hazardous materials and liquefied and compressed gases approved for international and domestic maritime transportation and indicate how each substance is categorized by its pollution potential, safe carriage requirements, chemical flammability, combustibility, and compatibility with other substances. This rule imposes no additional costs to chemical shippers or vessel owners.
This final rule is effective December 21, 2023.
The full notice and associated documents are available at www.regulations.gov under docket number USCG-2022-0327.
