ACTION: Proposed rule; extension of comment period.

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

SUMMARY: The Environmental Protection Agency (EPA) is extending the 
existing public comment period for a proposal published in the Federal 
Register on December 9, 2014. In that action, pursuant to the Clean Air 
Act, EPA proposed to determine that the Los Angeles-South Coast Air 
Basin (South Coast) air quality planning area in California has 
attained the 1997 annual and 24-hour fine particle (PM<INF>2.5</INF>) 
National Ambient Air Quality Standards. This proposed determination is 
based upon complete (or otherwise validated), quality-assured, and 
certified ambient air monitoring data showing that the area has 
monitored attainment of the 1997 annual and 24-hour PM<INF>2.5</INF> 
standards based on the 2011-2013 monitoring period. If the EPA 
finalizes this determination of attainment, the requirements for the 
area to submit certain State implementation plan revisions shall be 
suspended for so long as the area continues to attain the 1997 annual 
and 24-hour PM<INF>2.5</INF> standards. One commentor requested an 
extension of the comment period for this proposed rulemaking. EPA is 
now extending the public comment period for fourteen days.

9, 2014 (79 FR 72999) is extended. Comments must be received on or
