National Emission Standards for Hazardous Air Pollutants: Nutritional Yeast Manufacturing Risk and Technology Review

Riepilogo

The Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Manufacturing of Nutritional Yeast source category. The proposed amendments address the results of the residual risk and technology reviews (RTRs) conducted as required under the Clean Air Act (CAA) as well as other actions deemed appropriate during the review of these standards. The proposed amendments include revising the form of the fermenter volatile organic compounds (VOC) emission limits, changing the testing and monitoring requirements, and updating the reporting and recordkeeping requirements.
