SUMMARY: The Environmental Protection Agency (EPA) is extending the 
comment period for a proposed rule published February 2, 2024. The

2024. In response to requests from several commenters, the EPA is 
extending the comment period for the proposed action to April 3, 2024.

DATES: The comment period for the proposed rule published on February

Regulations.gov, follow the online instructions for submitting 
comments. Once submitted, comments cannot be edited or removed from

SUPPLEMENTARY INFORMATION: On February 2, 2024, the EPA published a 
proposal to disapprove a state implementation plan revision submitted 
by the State of California to meet Clean Air Act (CAA) requirements for 
the 1997 8-hour ozone national ambient air quality standards (NAAQS) in 
the Los Angeles-South Coast Air Basin, California ozone nonattainment 
area. This submission, titled ``Final Contingency Measure Plan--
Planning for Attainment of the 1997 80 ppb 8-hour Ozone Standard in the 
South Coast Air Basin,'' addresses the CAA requirements for the 
submission of contingency measures that will be implemented if 
emissions reductions from anticipated technologies associated with the 
area's 1997 ozone NAAQS attainment demonstration are not achieved. For 
more detailed information about this matter, please refer to the 
February 2, 2024 Federal Register document.
    The notice of proposed rulemaking initially provided for comments 
to be submitted to the EPA on or before March 4, 2024 (a 30-day public 
comment period). The EPA received several comments requesting an 
extension of the comment period. To ensure the public has sufficient 
time to evaluate the proposal and develop comments, the EPA is 
extending the comment period until April 3, 2024.

    Dated: February 23, 2024.

Acting Director, Air and Radiation Division, Region IX.
