ASTA Comments on EPA's Advanced Notice of Proposed Rulemaking on EtO Emissions

This document is a proposal to the Environmental Protection Agency's (EPA) ChemSAC calling for the establishment of tolerances for propylene oxide (PPO) on turmeric, ginger, sesame seeds, and capsicums on the basis of available residue data on other spice commodities to facilitate alternatives to ethylene oxide.

On March 3, 2026, ASTA submitted a follow-up letter to the U.S. Environmental Protection Agency providing information on the historical classification and commercial treatment of Mexican oregano and sassafras with ethylene oxide.
