Developments in EPA's Ethylene Standard

It has been more than 10 years since the finalization of EPA’s Ethylene Production rules that regulate hazardous air pollutants at ethylene facilities (Generic MACT II, Ethylene Production, 40 CFR Part 63 Subparts YY, XX, UU, 67 Federal Register 46,258, July 12, 2002).  As per the Clean Air Act, EPA must review each air toxics rule for residual risk and technological developments eight years after a rule is finalized.

 EPA has begun working on this mandatory review, and this presentation will highlight recent ACC activities and discussions with EPA regarding this review, as well as possible implications of a revised Ethylene standard.
