What the agency says
The U.S. Environmental Protection Agency (EPA) is finalizing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Polyether Polyols (PEPO) Production source category ("PEPO NESHAP") under Clean Air Act (CAA) section 112. Specifically, the EPA is finalizing certain ethylene oxide (EtO)- specific standards pursuant to CAA section 112(d)(6) rather than finalizing the proposed second residual risk review and corresponding amendments pursuant to CAA section 112(f)(2). In addition, the EPA is taking final action addressing certain issues raised in an administrative petition for reconsideration. Lastly, the EPA is finalizing maximum achievable control technology (MACT) standards for certain emission points, work practice standards for certain activities where alternatives are appropriate, performance testing requirements once every five years for certain process vents, and electronic reporting requirements for performance test reports, flare management plans, and periodic reports.
