1-Bromopropane (1-BP); Regulation Under the Toxic Substances Control Act (TSCA). Federal Register EPA notice of proposed rule. Summary: “EPA determined that 1-BP presents an unreasonable risk of injury to health due to the significant adverse health effects associated with exposure to 1-BP, including neurotoxicity, developmental toxicity from acute and chronic inhalation exposures and dermal exposures, and cancer from chronic inhalation exposures. TSCA requires that EPA address by rule any unreasonable risk of injury to health or the environment identified in a TSCA risk evaluation and apply requirements to the extent necessary so the chemical no longer presents unreasonable risk. To address the identified unreasonable risk, EPA is proposing requirements to, among other things, prevent consumer access to the chemical, restrict the industrial and commercial use of the chemical while also allowing for a reasonable transition period where an industrial and commercial use of the chemical is being prohibited, and protect workers from the unreasonable risk of 1-BP while on the job.”
