{"abstract":"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.","action":"Proposed rule.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2016/12/21/2016-30474.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"81 FR 93653","comment_url":null,"comments_close_on":"2017-01-20","correction_of":null,"corrections":[],"dates":"Any comments must arrive by January 20, 2017.","disposition_notes":null,"docket_ids":["EPA-R09-OAR-2016-0669","FRL-9956-67-Region 9"],"dockets":[{"supporting_documents":[{"title":"82 FR 8499_January 26 2017","document_id":"EPA-R09-OAR-2016-0669-0025"},{"title":"A-3rev.
