EPA is taking a critical first step forward to expand the scope of TRI reporting requirements to include certain contract sterilization facilities that are not currently reporting on ethylene oxide (EtO) releases. Under EPCRA, the EPA Administrator has discretionary authority to extend TRI reporting requirements to specific facilities based on a chemical's toxicity, the facility's proximity to other facilities that release the chemical or to population centers, any history of releases of the chemical at the facility, or other factors that the Administrator deems appropriate.
