Public Hearing for the Secondary National Ambient Air Quality 
Standards for Oxides of Nitrogen, Oxides of Sulfur, and Particulate 
Matter

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notification of public hearing.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is announcing that a 
virtual public hearing will be held for the proposed action titled, 
``Review of the Secondary National Ambient Air Quality Standards for 
Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter'' which is 
published elsewhere in this Federal Register. The hearing will be held 
on May 8, 2024. Based on the EPA's review of the ecological air quality 
criteria and the secondary national ambient air quality standards 
(NAAQS) for oxides of nitrogen (N oxides), oxides of sulfur 
(SOX), and particulate matter (PM), the EPA is proposing to 
revise the existing secondary SO2 standard. Additionally, 
the Agency proposes to retain the existing secondary standards for N 
oxides and PM. The EPA also proposes revisions to data handling 
requirements for the proposed secondary SO2 standard.

DATES: The EPA will hold a virtual public hearing on May 8, 2024. 
(Please refer to the SUPPLEMENTARY INFORMATION section for additional 
information on the public hearing).

FOR FURTHER INFORMATION CONTACT: For information or questions about the 
public hearing, please contact the public hearing team at [email protected] or 919-541-3650. For information or questions regarding 
the review of the secondary NAAQS for oxides of nitrogen, oxides of 
sulfur, and particulate matter, please contact Ms. Ginger Tennant, 
Health and Environmental Impacts Division, Office of Air Quality 
Planning and Standards, U.S. Environmental Protection Agency, Mail Code 
C539-04, Research Triangle Park, NC 27711; telephone: (919) 541-4072;

SUPPLEMENTARY INFORMATION: 
    I. General Information. The EPA is reviewing the secondary NAAQS 
for ecological effects of N oxides, SOX, and PM as required 
by section 109 (42 U.S.C. 7409) of the Clean Air Act. The proposed 
action for which the EPA is holding a public hearing is published 
elsewhere in this Federal Register and is available at https://www.epa.gov/naaqs/nitrogen-dioxide-no2-and-sulfur-dioxide-so2-secondary-standards-federal-register-notices. The public hearing will 
provide interested parties the opportunity to present data, views, or 
arguments concerning the EPA's proposed decisions in the review of the 
secondary NAAQS for ecological effects of SOX, N oxides and 
PM. Written statements and supporting information submitted during the 
comment period will be considered with the same weight as any oral 
comments and supporting information presented at the public hearing.
    A. Participation in Virtual Public Hearings: The public hearing 
will be held via virtual platform on May 8, 2024, and will convene at 
11:00 a.m. Eastern Time (ET). The hearing will

minutes after the last pre-registered speaker has testified. The EPA 
will announce any changes to the schedule or hearing and further 
details at https://www.epa.gov/so2-pollution/public-hearing-proposed-decision-so2-no2-and-pm-secondary-national-ambient-air.
    The EPA will begin registering speakers for the hearing upon

follow the schedule as closely as possible on the day of the hearing; 
however, please plan for the hearings to run either ahead of schedule 
or behind schedule. Each commenter will have up to 5 minutes to provide 
oral testimony. The EPA encourages commenters to provide the EPA with a
