SUPPLEMENTARY INFORMATION: On August 1, 2025, EPA published a proposed 
rule titled ``Reconsideration of 2009 Endangerment Finding and 
Greenhouse Gas Vehicle Standards'' (90 FR 36288). The public comment 
for this proposed rule was scheduled to end on September 15, 2025. The 
public hearing on this rule is scheduled for August 19, 20, and 21, 
2025. In EPA's Federal Register notice announcing the public hearing 
(90 FR 36125), EPA stated the agency would hold the public hearing on 
August 19 and 20, and EPA would consider adding a third day, August 21, 
if needed. EPA has now decided to add a third day (August 21, 2025) and 
is considering adding a fourth day (August 22, 2025). The Clean Air Act 
requires that the record of proceedings allowing oral presentation of 
data, views, and arguments on a proposed rule be kept open for 30 days 
after completion of the proceeding to provide an opportunity for 
submission of rebuttal and supplementary information. 42 U.S.C. 
7607(d)(5). Because EPA plans to hold a third of public hearing for 
this proposed rule, and is considering adding a fourth day, the final 
``proceeding allowing oral presentation of data, views, and 
arguments,'' will be held on August 21, 2025, and potentially on August 
22, 2025. For this reason, the public comment period for this proposed 
rule is extended and will now end on September 22, 2025.

William Charmley,
Director, Assessment and Standards Division, Office of Transportation 
and Air Quality.
