On June 12, 2020, the U.S. Environmental Protection Agency (EPA) Administrator signed a final notice to grant a petition to add 1-Bromopropane (1-BP) to the Clean Air Act (CAA) list of air toxics. Once this substance is added, the EPA may revise or create new emission standards for source categories that emit 1-BP. Use of 1-BP has increased over the past two decades. It is used as a solvent in many industries and products such as aerosol glues, asphalt production, synthetic fiber production, and dry cleaning.* It can have adverse health impacts on workers and anyone who is exposed to it for an extended period of time. The current final notice does not have any direct impacts. No regulatory requirements will come into effect until EPA adds 1-BP to the CAA list of air toxics.
