(160a) Ethylene Risk and Technology Review What's the Outlook?

Per the court-mandated timeline, the EPA is currently working through the statutorily-required risk and technology review (RTR) for the ethylene NESHAP (40 CFR, Part 63, Subpart XX and Subpart YY) process. The proposed rule, was published in the Federal Register October 9, 2019, and will impact current ethylene operations. The proposed rule mirrors certain aspects of the refinery rule, such as the flare, heat exchange systems and PRD refinery language, decoke emissions (both decoke to the fire box and decoke to an atmospheric pot) and waste water emissions.

This paper will discuss the proposed rule and the potential impact on the ethylene facilities.
