The Environmental Protection Agency (EPA) is taking direct final action 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 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. This determination suspends 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 for as long as the area continues to meet those standards.
