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.

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.
