Comment & Consultation

TCOTS Link

U.S. Environmental Protection Agency (EPA) is initiating consultation with federally recognized Indian Tribes to obtain input on the agency’s proposed amendments to the 2009 National Emission Standards for Hazardous Air Pollutants that apply to chemical manufacturing area sources, also known as the CMAS NESHAP.

In this rulemaking, the EPA is proposing amendments that would reduce the emissions of hazardous air pollutants (HAP), including ethylene oxide (EtO), emitted by facilities subject to the CMAS NESHAP. After undertaking a review of the rule as required by section 112(d)(6) of the Clean Air Act, 42 U.S.C. § 7412(d)(6), the EPA is proposing to lower the emissions of HAP produced by these facilities by updating leak detection practices, setting new standards for emissions from pressure relief devices, and requiring performance testing to ensure continued compliance. In addition, the EPA is proposing EtO-specific standards and practices to reduce the amount of EtO emitted by these facilities. The EPA estimates that these proposed amendments to the CMAS NESHAP would reduce EtO emissions by approximately 4.6 tons per year (tpy), emissions of other HAPs by approximately 158 tpy, and emissions of smog-forming volatile organic compounds by 1,557 tpy.

The proposed rule will publish in the Federal Register in the coming weeks, and the EPA will be accepting public comments for 60 days after the publication date in the Federal Register.

If your Tribe has questions about the proposed action or would like to request government-to-government consultation with the EPA on this rulemaking, please have your staff contact Regina Chappell, Tribal Consultation Advisor, at chappell.regina@epa.gov or (919) 541-3650, by February 28, 2025. We also encourage you to submit written comments to the docket to identify any information that you believe may be relevant to the development of the final rule. Tribes may submit written comments at https://www.regulations.gov/, Docket ID No. EPA-HQ-OAR-2024-0419, any time during the open comment period following publication in the Federal Register.

Based on public feedback, EPA has updated two chapters in its Water Quality Standards (WQS) Handbook and developed a third:

• Chapter 2: Designation of Uses. This revised chapter discusses ways to express designated uses; how to designate, revise, and remove uses; how to protect downstream uses; and when to reassess designated uses.
• Chapter 4: Antidegradation. This revised chapter discusses how to use the various tiers of antidegradation protection, how to develop an antidegradation policy, and recommendations and considerations when developing and implementing an antidegradation implementation method.
• New Chapter: WQS Variances. This chapter reflects EPA’s policy and guidance on the development and implementation of WQS variances consistent with the regulatory requirements in 40 CFR 131.14.

EPA seeks your comments on these revisions.  

• Submit comments 

EPA will host informational webinars during the public comment period to provide an overview of the chapters and an opportunity for participants to ask clarifying questions: 

• Webinar for the general public: Feb. 4
• Webinar for Tribes: Feb. 6

EPA has announced draft national recommendations for health-based levels of per- and polyfluoroalkyl substances (PFAS) in waterbodies. Once final, these recommended criteria can be used by states and authorized Tribes to set water quality standards that help protect people from exposure through consuming water, fish and shellfish from inland and nearshore waterbodies that may be polluted by PFAS. Human health criteria are not regulatory requirements and do not, on their own, compel any action. Rather they are information for entities, including state and Tribal regulators, to consider when making policy decisions that protect water quality.

The Clean Water Act requires EPA to promulgate test methods that analyze pollutants in wastewater. On December 6, EPA released a proposed rule to add or revise analytical methods, or test procedures for measuring pollutants in wastewater. Specifically, EPA is proposing to add new agency test methods for per- and polyfluoroalkyl substances (PFAS) and polychlorinated biphenyl (PCB) chemicals and add methods previously published by voluntary consensus standard bodies such as ASTM International, or other vendors. When finalized, industries, states, and municipalities would use these methods for reporting under the EPA’s National Pollutant Discharge Elimination System permit program. The agency will accept public comments on the proposed rule for 30 days upon its publication in the Federal Register.

EPA is initiating consultation and coordination with Alaska Native Claims Settlement Act (ANCSA) regional and village corporations on the development of the sixth Unregulated Contaminant Monitoring Rule (UCMR 6) for public drinking water systems. You may be interested in UCMR 6 if you own or operate a public drinking water system. 

The UCMR program collects data for contaminants suspected to be present in drinking water, but do not have health-based standards set under the Safe Drinking Water Act (SDWA). SDWA requires the EPA to issue a new list of no more than 30 unregulated contaminants for monitoring every five years. The data collected during monitoring serve as a primary source of occurrence and exposure information that helps the agency make determinations about future drinking water regulations and other actions to protect public health under SDWA.

EPA is initiating consultation with federally recognized Tribes for input on the proposed amendments to the Standards of Performance for new, modified, and reconstructed stationary combustion turbines and stationary gas turbines. The proposal is seeking to reduce nitrogen oxide (NOx) emissions for most turbines. The consultation is expected to run through February 15, 2025

If your Tribe has questions about the proposed action or would like to request government-to-government consultation with the EPA on this rulemaking, please have your staff contact Regina Chappell, Tribal Consultation Advisor, at chappell.regina@epa.gov or (919) 541-3650, by February 1, 2025

As part of EPA’s strategy to learn more about new and emerging technologies and alternative methodologies for regulating emissions from municipal solid waste landfills, EPA opened a non-regulatory docket to gather input on ways to streamline, improve, and harmonize the current suite of emissions regulations that cover these sources. EPA has developed a series of white papers on new and emerging technologies, alternative approaches to regulating landfill emissions, and landfill work practice methodologies that may assist with future rulemaking.

• Submit comments and view the white papers.

On Nov. 22, EPA proposed to strengthen limits on emissions of nitrogen oxides (NOx) from most new, modified, and reconstructed fossil fuel-fired stationary combustion turbines, reducing exposure to dangerous air pollution for nearby communities. The proposal would ensure that new turbines built at power plants or industrial facilities — especially large ones that could operate for decades — would be among the most efficient and lowest-emitting turbines ever built. NOx contributes to harmful health effects, such as asthma and respiratory infections, and reacts with other volatile organic compounds to form ozone (i.e., smog) and fine particulate matter.   

• Read the press release.

EPA will accept comments for 90 days after the proposal is published in the Federal Register.
