View Rule

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Ethylene Oxide Commercial Sterilization and Fumigation Operations were finalized in December 1994 (59 FR 62585). The standards require existing and new major sources to control emissions to the level achievable by the maximum achievable control technology (MACT) and require existing and new area sources to control emissions using generally available control technology (GACT). EPA completed a residual risk and technology review for the NESHAP in 2006 and, at that time, concluded that no revisions to the standards were necessary. In this action, EPA will conduct the second technology review for the NESHAP and also assess potential updates to the rule. To aid in this effort, EPA issued an advance notice of proposed rulemaking (ANPRM) that solicited comment from stakeholders and undertook a Small Business Advocacy Review (SBAR) panel which is needed when there is the potential for significant economic impacts to small businesses from any regulatory actions being considered.
