EPA Finds 16 Conditions of Use of 1-BP Pose an Unreasonable Risk to Workers, ONUs, Consumers, and Bystanders

On August 12, 2020, the U.S. Environmental Protection Agency (EPA) announced the availability of the final risk evaluation for 1-bromopropane (1-BP).  85 Fed. Reg. 48687.  After evaluating 25 conditions of use, EPA determined that 16 present an unreasonable risk to workers, occupational non-users (ONU), consumers, and bystanders.  For those conditions of use for which EPA has found an unreasonable risk, EPA states that it must take regulatory action to address that unreasonable risk through risk management measures enumerated in the Toxic Substances Control Act (TSCA).  EPA has also determined that specific conditions of use do not present unreasonable risk of injury to health or the environment.  EPA notes that for those conditions of use for which EPA has found no unreasonable risk to health or the environment, its determination is a final agency action and is issued via order in the risk evaluation.  A detailed analysis and commentary is available in our August 11, 2020, memorandum, “EPA Publishes Final Risk Evaluation for 1-BP.”
