| 2019-24573 | National Emission Standards for Hazardous Air Pollutants: Miscellaneous Organic Chemical Manufacturing Residual Risk and Technology Review | Proposed Rule | The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Miscellaneous Organic Chemical Manufacturing source category. The EPA is proposing decisions concerning the residual risk and technology review (RTR), including proposing amendments pursuant to the technology review for equipment leaks and heat exchange systems, and also proposing amendments pursuant to the risk review to specifically address ethylene oxide emissions from storage tanks, process vents, and equipment leaks. The EPA is also proposing amendments to correct and clarify regulatory provisions related to emissions during periods of startup, shutdown, and malfunction (SSM), including removing general exemptions for periods of SSM, adding work practice standards for periods of SSM where appropriate, and clarifying regulatory provisions for certain vent control bypasses. Lastly, the EPA is proposing 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 add provisions for electronic reporting of performance test results and reports, performance evaluation reports, and compliance reports. We estimate that, if finalized, these proposed amendments (not including the potential excess emission reductions from flares) would reduce hazardous air pollutants (HAP) emissions from this source category by 116 tons per year (tpy) and would reduce ethylene oxide emissions from this source category by approximately 10 tpy. | 2019-12-17 | 2019 | 12 | https://www.federalregister.gov/documents/2019/12/17/2019-24573/national-emission-standards-for-hazardous-air-pollutants-miscellaneous-organic-chemical | https://www.govinfo.gov/content/pkg/FR-2019-12-17/pdf/2019-24573.pdf | Environmental Protection Agency | 145 | The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Miscellaneous Organic Chemical Manufacturing source category.
