This action finalizes amendments to the New Source Performance Standards (NSPS) that apply to the Synthetic Organic Chemical Manufacturing Industry (SOCMI) and amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) that apply to the SOCMI (more commonly referred to as the Hazardous Organic NESHAP or HON) and Group I and II Polymers and Resins (P&R I and P&R II, respectively) Industries. The EPA is finalizing decisions resulting from the Agency's technology review of the HON and the P&R I and P&R II NESHAP, and its review of the NSPS that apply to the SOCMI. The EPA is also finalizing amendments to the NSPS for equipment leaks of volatile organic compounds (VOC) in SOCMI based on its reconsideration of certain issues raised in an administrative petition for reconsideration. Furthermore, the EPA is finalizing emission standards for ethylene oxide (EtO) emissions and chloroprene emissions after considering the results of a risk assessment for the HON and for Neoprene Production processes subject to the P&R I NESHAP, and is finalizing a fenceline monitoring work practice standard for certain hazardous air pollutants (HAP). Lastly, the EPA is finalizing the removal of exemptions from standards for periods of startup, shutdown, and malfunction (SSM), adding work practice standards for such periods where appropriate, finalizing standards for previously unregulated HAP, and adding provisions for electronic reporting of performance test reports and periodic reports.This final rule is effective on 15 July 2024. The incorporation by reference (IBR) of certain publications listed in the rule is approved by the Director of the Federal Register as of 15 July 2024. The incorporation by reference of certain other material listed in the rule was approved by the Director of the Federal Register as of 17 October 2000 and 16 November 2007.Title 40 Code of Federal Regulations (CFR) Parts 60 and 63This final rule and previous actions notified under the symbol G/TBT/N/USA/1995 is identified by Docket Number EPA-HQ-OAR-2022-0730.
