EPA issued a proposed rule on August 8, 2024, to address the unreasonable risk of injury to human health presented by 1-bromopropane (1-BP) under its COUs as documented in EPA’s August 2020 Risk Evaluation for 1-BP and the December 2022 Revised Risk Determination for 1-BP prepared under TSCA. 89 Fed. Reg. 65066. To address the identified unreasonable risk, EPA proposes requirements to, among other things, prevent consumer access to 1-BP, restrict the industrial and commercial use of 1-BP while also allowing for a reasonable transition period where an industrial and commercial use of 1-BP is being prohibited, and protect workers from the unreasonable risk of 1-BP while on the job. EPA will hold a webinar on August 28, 2024, to provide an overview of the proposed rule. Comments are due September 23, 2024. EPA states that under the Paperwork Reduction Act, “comments on the information collection provisions are best assured of consideration if the Office of Management and Budget (OMB) receives a copy of your comments on or before September 9, 2024.” For more information about the proposed rule, please read the full memorandum.
