ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R09-OAR-2016-0772; FRL-9958-18-Region 9]


Determination of Attainment and Approval of Base Year Emissions 
Inventories for the Imperial County, California Fine Particulate Matter 
Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is determining that 
the Imperial County, California Moderate nonattainment area (``the 
Imperial County NA'') has attained the 2006 24-hour fine particulate 
matter (PM2.5) national ambient air quality standard 
(NAAQS). The EPA is also approving a revision to California's state 
implementation plan (SIP) consisting of the 2008 winter and annual base 
year emissions inventories for the Imperial County NA submitted by 
California Air Resources Board on January 9, 2015.

DATES: Any comments on this proposal must arrive by April 12, 2017.

SUPPLEMENTARY INFORMATION: Throughout this document, ``we,'' ``us'' and 
``our'' refer to the EPA. This proposal pertains to the 2008 winter and 
annual base year emissions inventories in a plan submitted by the 
California Air Resources Board to address the attainment planning 
requirements for the Imperial County NA. It also addresses our 
determination (also referred to as a clean data determination or CDD) 
that the Imperial County NA has attained the 2006 24-hour 
PM2.5 NAAQS. In the Rules and Regulations section of this 
issue of the Federal Register, we are approving the 2008 winter and 
annual base year emissions inventories and making this CDD in a direct 
final action without prior proposal because we believe this SIP 
revision and CDD are not controversial. If, however, we receive adverse 
comments we will publish a timely withdrawal of the direct final rule 
and address the comments in subsequent action based on this proposed 
rule. If we receive adverse comment on a distinct provision of this 
rulemaking, we will publish a timely withdrawal in the Federal Register 
indicating which provision we are withdrawing. The provision that is 
not withdrawn will become effective on the date set out above, 
notwithstanding adverse comment on the other provision.
    We do not plan to open a second comment period, so anyone 
interested in commenting should do so at this time. If we do not 
receive adverse comments, no further activity is planned. For further 
information, please see the direct final action.

    Dated: January 3, 2017.
Alexis Strauss,
Acting Regional Administrator, Region IX.
