The bill orders the EPA Administrator to update the federal standards for ethylene oxide emissions under the Clean Air Act. Within 180 days, the standards must be revised using a 2016 EPA carcinogenicity report and must apply maximum achievable control technology to chamber exhaust vents and to both area and major sources. After the new standards are set, the EPA must conduct a residual risk review and must publicly announce any violations within 30 days, with Inspector General oversight if the notification is missed.

Key Provisions

  • Amend subpart O of part 63 to revise ethylene oxide emission standards based on the 2016 EPA inhalation carcinogenicity report, within 180 days of enactment.
  • Apply maximum achievable control technology requirements to chamber exhaust vents and to area and major sources of ethylene oxide.
  • Conduct a residual risk assessment of the revised standards within 180 days after they are finalized, as required by Clean Air Act section 112(f)(2).
  • Notify the public of any violation of the revised standards within 30 days of the EPA learning of the violation.
  • If the EPA fails to notify, the EPA Inspector General must investigate the failure, assess public health risks, and recommend steps to ensure future compliance.
