Finding of Substantial Inadequacy of Implementation Plan; Call 
for California State Implementation Plan Revision; South Coast; 
Reopening of Comment Period

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; reopening of comment period.

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

SUMMARY: EPA is reopening the public comment period for a proposal 
published in the Federal Register on September 19, 2012. In that 
action, in response to a remand by the Ninth Circuit Court of Appeals, 
and pursuant to the Clean Air Act, EPA proposed to find that the 
California State Implementation Plan (SIP) for the Los Angeles-South 
Coast Air Basin (South Coast) is substantially inadequate to comply 
with the obligation to adopt and implement a plan providing for 
attainment of the 1-hour ozone standard. If EPA finalizes this proposed 
finding of substantial inadequacy as proposed, California would be 
required revise its SIP to correct these deficiencies within 12 months 
of the effective date of our final rule. Two commentors requested an 
extension of the comment period for this proposed rulemaking. EPA is 
now reopening the public comment period.

DATES: The comment period for the proposed rule published on September 
19, 2012 (77 FR 58072) is reopened. Comments must be received on or 
before November 8, 2012.

SUPPLEMENTARY INFORMATION: EPA published a proposed rule on September 
19, 2012 (77 FR 58072). In that action, in response to a remand by the

substantially inadequate to comply with the obligation to adopt and 
implement a plan providing for attainment of the 1-hour ozone standard.
