Learn More🏭EPA Extends Comment Period for National Emission Standards Proposal
On January 22, 2025, the U.S. Environmental Protection Agency (EPA) proposed a rule titled "National Emission Standards for Hazardous Air Pollutants: Chemical Manufacturing Area Sources Technology Review." The EPA is extending the comment period on this proposed rule, which was scheduled to close on March 24, 2025. The comment period will now remain open until April 14, 2025, to allow additional time for stakeholders to review and comment on the proposal.
Learn More🧪EPA Extends Reporting Deadline for Chemical Health Data
In response to requests from stakeholders, the Environmental Protection Agency (EPA or Agency) is amending the deadline for reporting pursuant to the Toxic Substances Control Act (TSCA) Health and Safety Data Reporting rule, which requires manufacturers (including importers) of 16 specified chemical substances to report certain lists and copies of unpublished health and safety studies to EPA. Specifically, EPA is amending the deadline from March 13, 2025, to June 11, 2025, for one of the 16 chemical substances (vinyl chloride) and to September 9, 2025, for the remaining 15 chemical substances. The Health and Safety Data Reporting Rule requires manufacturers (including importers) of certain chemical substances to submit lists and copies of certain unpublished health and safety studies to EPA.

EPA is required under the Toxic Substances Control Act (TSCA) to make information publicly available and to publish information in the Federal Register pertaining to submissions under TSCA, including notice of receipt of a Premanufacture notice (PMN), Significant New Use Notice (SNUN) or Microbial Commercial Activity Notice (MCAN), including an amended notice or test information; an exemption application (Biotech exemption); an application for a test marketing exemption (TME), both pending and/or concluded; a notice of commencement (NOC) of manufacture (including import) for new chemical substances; and a periodic status report on new chemical substances that are currently under EPA review or have recently concluded review. This document covers the period from 12/01/2024 to 12/31/2024.
Learn More🌎Proposed EPA Regulations on Ethylene Oxide Emissions Standards
The Environmental Protection Agency (EPA) is proposing to establish a new area source category to address chemical manufacturing process units (CMPUs) using ethylene oxide (EtO). The EPA is proposing to list EtO in table 1 to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Chemical Manufacturing Area Sources (referred to as the CMAS NESHAP in this document) and to add EtO- specific requirements to the CMAS NESHAP. The EPA is also proposing to add a fenceline monitoring program for EtO. In addition, the EPA is proposing new requirements for pressure vessels and pressure relief devices (PRDs). This proposal also presents the results of the EPA's technology review of the CMAS NESHAP as required under the Clean Air Act (CAA). As part of this technology review, the EPA is proposing to add new leak detection and repair (LDAR) requirements to the CMAS NESHAP for equipment leaks in organic HAP service and heat exchange systems. The EPA is also proposing performance testing once every 5 years and to add provisions for electronic reporting. We estimate that the proposed amendments to the CMAS NESHAP, excluding the proposed EtO emission standards, would reduce hazardous air pollutant (HAP) emissions from emission sources by approximately 158 tons per year (tpy). Additionally, the proposed EtO emission standards are expected to reduce EtO emissions by approximately 4.6 tpy.
