2024 Workshops To Obtain Input on Initial Draft Materials for the Integrated Science Assessment (ISA) for Oxides of Nitrogen-Health Criteria
The Environmental Protection Agency (EPA) is preparing an Integrated Science Assessment (ISA) as part of the review of the primary (health-based) National Ambient Air Quality Standards (NAAQS) for oxides of nitrogen. As part of this review, EPA is announcing a series of public workshops to evaluate preliminary draft materials that will inform the development of the ISA for oxides of nitrogen. Preliminary materials are not being released externally but will be provided to the panelists to guide discussions that will inform the development of the draft ISA for oxides of nitrogen. The workshops are being organized by EPA's Center for Public Health and Environmental Assessment (CPHEA) within the Office of Research and Development and will be held by webinar and teleconference on October 8, October 30, and October 31. Members of the public may attend the webinars as observers. Space in the teleconferences may be limited, and reservations will be accepted on a first-come, first-served basis.
Review of Final Rule Reclassification of Major Sources as Area Sources Under Section 112 of the Clean Air Act
The EPA is finalizing requirements for sources that reclassify from major source status to area source status under the National Emission Standards for Hazardous Air Pollutants (NESHAP) program. The requirements of this final rule apply to all sources that choose to reclassify after September 10, 2024. The final amendments include a requirement that sources subject to certain major source NESHAP used to meet the Agency's obligations under the Clean Air Act (CAA) for seven specific persistent and bioaccumulative pollutants must remain subject to those NESHAP even if the sources reclassify to area source status. This requirement is based on the EPA's analysis of the statute and of comments received on the EPA's 2023 proposal to amend requirements for NESHAP-regulated sources that choose to reclassify from major to area source status. These final amendments will assure that sources accounting for not less than 90 per centum of the aggregate emissions of each persistent and bioaccumulative hazardous air pollutant (HAP) listed in CAA remain subject to standards promulgated under the CAA, as the Act requires, and will thereby ensure continued health protections from NESHAP that regulate those HAP. Additionally, we are finalizing clarifications to notification requirements and updating language regarding submittal of confidential business information.
Proposed Consent Decree, Clean Air Act Citizen Suit
In accordance with section 113(g) of the Clean Air Act, as amended ("CAA" or "the Act"), the Environmental Protection Agency ("EPA" or "the Agency") is providing notice of a proposed consent decree in Louisiana Environmental Action Network, et al. v. Regan, No. 1:23-cv-2714-DLF (D.D.C). On December 7, 2023, Plaintiffs Louisiana Environmental Action Network, People Concerned About Chemical Safety, and Sierra Club (collectively Plaintiffs) filed an amended complaint in the United States District Court for the District of Columbia. Plaintiffs alleged that: EPA failed to perform certain non- discretionary duties in accordance with the Act to "review, and revise as necessary" the National Emission Standards for Hazardous Air Pollutants ("NESHAP") for the Polyether Polyols Production source category, at least every eight years; and EPA's failure to timely issue a new final rule or other final action on the 2014 petition for reconsideration (the Reconsideration Petition) submitted by Louisiana Environmental Action Network and Sierra Club for the NESHAP as promulgated in 2014. The proposed consent decree would establish deadlines for EPA to take actions.
