December 17th, 2019 by Ann Rippe

Proposed Rule Change
Summary: EPA is proposing amendments to the NESHAP for the miscellaneous organic chemical manufacturing source category (40 CFR 63, Subpart FFFF) as a result of its residual risk and technology review (RTR). Specifically, EPA is proposing amendments for equipment leaks and heat exchange systems as a result of the technology review, and is proposing amendments to address ethylene oxide emissions from storage tanks, process vents, and equipment leaks as a result of the risk review. Additionally, EPA is proposing to correct and clarify provisions related to emissions during periods of startup, shutdown and malfunction; to add monitoring and operational requirements for flares that control ethylene oxide emissions and flares used to control emissions from processes that produce olefins and polyolefins; and to add provisions for electronic reporting of performance test results and reports, performance evaluation reports, and compliance reports.
