SUPPLEMENTARY INFORMATION: 
    Background: The CASAC was established pursuant to the Clean Air Act 
(CAA) Amendments of 1977, codified at 42 U.S.C. 7409(d)(2), to review 
air quality criteria and NAAQS and recommend to the EPA Administrator 
any new NAAQS and revisions of existing criteria and NAAQS as may be 
appropriate. The CASAC shall also: advise the EPA Administrator of 
areas in which additional knowledge is required to appraise the 
adequacy and basis of existing, new, or revised NAAQS; describe the 
research efforts necessary to provide the required information; advise 
the EPA Administrator on the relative contribution to air pollution 
concentrations of natural as well as anthropogenic activity; and advise 
the EPA Administrator of any adverse public health, welfare, social, 
economic, or energy effects which may result from various strategies 
for attainment and maintenance of such NAAQS. As amended, 5 U.S.C., 
App. Section 109(d)(1) of the Clean Air Act (CAA) requires that EPA 
carry out a periodic review and revision, as appropriate, of the air 
quality criteria and the NAAQS for the six ``criteria'' air pollutants, 
including oxides of nitrogen.
    The CASAC is a federal advisory committee chartered under the 
Federal Advisory Committee Act (FACA), 5

[[Page 64375]]

U.S.C. chapter 10, and conducts business in accordance with FACA and 
related regulations. The CASAC will comply with the provisions of FACA 
and all appropriate SAB Branch procedural policies. Pursuant to FACA 
and EPA policy, notice is hereby given that the CASAC will hold a 
public meeting to discuss a draft CASAC Report of EPA's ISA for 
NO<INF>X</INF>.
    Availability of meeting materials: All meeting materials, including 
the agenda, will be available on the CASAC web page at <a href="https://casac.epa.gov">https://casac.epa.gov</a>.
    Procedures for providing public input: Public comment for 
consideration by EPA's federal advisory committees and panels has a 
different purpose from public comment provided to EPA program offices. 
Therefore, the process for submitting comments to a federal advisory 
committee is different from the process used to submit comments to an 
EPA program office. Federal advisory committees and panels, including 
scientific advisory committees, provide independent advice to the EPA. 
Members of the public can submit relevant comments pertaining to the 
committee's charge or meeting materials. Input from the public to the 
CASAC will have the most impact if it provides specific scientific or 
technical information or analysis for the CASAC to consider or if it 
relates to the clarity or accuracy of the technical information. 
Members of the public wishing to provide comments should follow the 
instructions below to submit comments.
    Oral statements: In general, individuals or groups requesting an 
oral presentation virtually will be limited to three minutes. Each 
person making an oral statement should consider providing written 
comments as well as their oral statement so that the points presented 
orally can be expanded upon in writing. Persons interested in providing 
oral statements should contact the DFO listed in the FOR FURTHER 
INFORMATION CONTACT section; preferably via email, by October 26, 2026, 
to be placed on the list of registered speakers.
    Written statements: Written statements will be accepted throughout 
the advisory process; however, for timely consideration by CASAC 
members, statements should be submitted to the DFO by October 26, 2026. 
Written statements should be supplied by email to the DFO listed in the 
FOR FURTHER INFORMATION CONTACT section. Submitters are requested to 
provide an unsigned version of each document because the SAB Branch 
does not publish documents with signatures on its websites. Members of 
the public should be aware that their personal contact information, if 
included in any written comments, may be posted to the CASAC website. 
Copyrighted material will not be posted without the explicit permission 
of the copyright holder.
    Accessibility: For information on access or services for 
individuals with disabilities, please contact the DFO listed in the FOR 
FURTHER INFORMATION CONTACT section; at least ten business days before 
the meetings, to give the EPA as much time as possible to process your 
request.

V. Khanna Johnston,
Chief, Science Advisory Board Branch.
