On July 20, 2022, EPA published a draft revision to its risk determination for 1-bromopropane, also referred to as "1-BP." EPA proposed revisions to supersede the conditions of use previously issued in the 2020 1-BP evaluation. Due to recent policy changes, EPA is replacing its condition of use-specific unreasonable risk determinations with a determination of unreasonable risk for 1-BP as a whole chemical substance driven by certain condition of uses.
As part of the revision, EPA is removing the assumption of personal protective equipment use by workers, which means that 23 out of 25 conditions of use evaluated would drive the determination that 1-BP presents an unreasonable risk of injury to human health under its conditions of use. Two out of 25 conditions of use would not drive the unreasonable risk: commercial and consumer use of 1-BP in insulation for building and construction materials, and distribution in commerce.
Comments are due on August 19, 2022.
