Big Changes Proposed for SOCMI and Polymer and Resin NSPS and NESHAPs

On April 25, 2023, EPA proposed significant changes to the air toxics and new source performance standards (NSPS) for the synthetic organic chemical manufacturing industry (SOCMI) and the polymers and resins industries. [88 FR 25080] Changes to both applicability determinations and compliance requirements are proposed for the following standards:

If finalized, EPA estimates an annual HAP reduction of more than 6,000 tons by controlling the emissions at approximately 200 facilities, many located in Texas, Louisiana, and along the Ohio River Valley. VOC emissions may also be reduced by more than 23,000 tons annually, greatly reducing the amount of smog, or tropospheric ozone, in affected areas. The agency also believes 80% of emissions reduction would come from new flare requirements alone.

Here is a brief summary of some of the proposed changes:

More information on the proposal is available at EPA’s HON website, including a redline document of the proposed regulatory text changes and a list of facilities EPA knows to be covered by the proposed rule. Comments on the proposal may be submitted until June 26, 2023 via Docket ID No. EPA-HQ-OAR-2022-0730.
