[EPA-R09-OAR-2016-0669; FRL-9956-67-Region 9]


Determination of Attainment of the 2008 Ozone National Ambient 
Air Quality Standards; Mariposa County, California

AGENCY: The Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
determine that the Mariposa County, California Moderate Nonattainment 
Area (NAA) has attained the 2008 8-hour ozone National Ambient Air 
Quality Standards (NAAQS or ``standards''). This proposed determination 
is based on complete, quality-assured and certified data for 2013-2015. 
Preliminary data for 2016 are consistent with continued attainment of 
the standards in the Mariposa County NAA. If the determination is 
finalized as proposed, any unfulfilled obligations to submit revisions 
to the state implementation plan (SIP) related to attainment of the 
2008 ozone standards for the Mariposa County NAA will be suspended for 
as long as the area continues to meet those standards.

DATES: Any comments must arrive by January 20, 2017.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R09-
OAR-2016-0669 at http://www.regulations.gov, or via email to 
[email protected]. For comments submitted at Regulations.gov, follow 
the online instructions for submitting comments. Once submitted, 
comments cannot be edited or removed from Regulations.gov. For either 
manner of submission, the EPA may publish any comment received to its 
public docket. Do not submit electronically any information you 
consider to be Confidential Business Information (CBI) or other 
information whose disclosure is restricted by statute. Multimedia 
submissions (audio, video, etc.) must be accompanied by a written 
comment. The written comment is considered the official comment and 
should include discussion of all points you wish to make. The EPA will 
generally not consider comments or comment contents located outside of 
the primary submission (i.e., on the Web, cloud or other file sharing 
system). For additional submission methods, please contact the person 
identified in the FOR FURTHER INFORMATION CONTACT section. For the full

SUPPLEMENTARY INFORMATION: Throughout this document, whenever ``we,'' 
``us'' or ``our'' is used, we mean the EPA. In the Rules and 
Regulations section of this Federal Register, we are making a 
determination that the Mariposa County, California Moderate NAA has 
attained the 2008 8-hour ozone NAAQS as a direct final rule without 
prior proposal because the Agency views this action as noncontroversial 
and anticipates no adverse comments. A detailed rationale for this 
determination of attainment is set forth in the direct final rule. If 
we receive adverse comments, however, we will publish a timely 
withdrawal of the direct final rule and address the comments in 
subsequent action based on this proposed rule. 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 rule, which is located in the Rules and Regulations section of 
this Federal Register.

    Dated: December 2, 2016.

Acting Regional Administrator, Region IX.
