Description:  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 ap ply 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 E PA 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 w here 
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 ce rtain 
publications listed in the rule is approved by the Director of the Federal Register as of 15 July 2024.
