Chemical Sector MACT Update

Speaker: Christopher Ward

Although there has been a change in administration, the EPA is contending with several consent decree driven deadlines for completing multiple Part 63 risk and technology reviews with relevance to the chemical manufacturing industry. These include the final rules for chemical manufacturing area sources (CMAS), polyether polyols production (PEPO) units, and hazardous waste combustors (HWC). Additionally, the agency is working on the reconsideration of the hazardous organic NESHAP (HON).

This session will cover what we expected to see in the final versions of CMAS, PEPO, and HWC MACT (will include the details if final rules are complete by seminar). It will also include a status update on the HON reconsideration along with any known details on the proposal (expected spring/early summer 2026).
