{"abstract":"On January 5, 2018, the Environmental Protection Agency (EPA) published in the Federal Register an advanced notice of proposed rulemaking (ANPR) specifically requesting early input and comments on the Agency's interpretation that air quality monitoring data from 2015- 2017 support a finding that the Missouri Portion of the St. Louis nonattainment area attains the 1997 Annual National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM<INF>2.5</INF>). The notice also provided an evaluation of Missouri's 1997 Annual PM<INF>2.5</INF> NAAQS maintenance plan, which includes the 2008 and 2025 NO<INF>X</INF> and PM<INF>2.5</INF> motor vehicle emission budgets (MVEBs) and established the 2008 base year emissions inventory. EPA received no comments on the ANPR. EPA is now taking direct final action on three items, consistent with the ANPR. First, EPA is approving the state's request to redesignate the Missouri portion of the St. Louis MO-IL nonattainment area to attainment for the 1997 Annual PM<INF>2.5</INF> NAAQS as the monitoring values demonstrate the area attains the standard. Second, EPA is approving the state implementation plan (SIP) revision containing a maintenance plan for the Missouri portion of the area including the motor vehicle emissions budget. Third, EPA is approving Missouri's 2008 base year emissions inventory in accordance with section 172(c)(3) of the CAA.","action":"Direct final 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/2018/08/03/2018-16003.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40},{"chapter":null,"citation_url":null,"part":81,"title":40}],"citation":"83 FR 38033","comment_url":null,"comments_close_on":"2018-09-04","correction_of":null,"corrections":[],"dates":"This direct final rule will be effective October 2, 2018, without further notice, unless EPA receives adverse comment by September 4, 2018.
