{"abstract":"The Environmental Protection Agency (EPA) is taking direct final action to approve a portion of a state implementation plan (SIP) revision submitted by the State of Delaware. The Clean Air Act's (CAA) good neighbor provision requires EPA and states to address the interstate transport of air pollution that affects the ability of downwind states to attain and maintain the national ambient air quality standards (NAAQS). Specifically, the good neighbor provision requires each state in its SIP to prohibit emissions that will significantly contribute to nonattainment, or interfere with maintenance, of a NAAQS in a downwind state. Delaware has submitted a SIP revision that addresses the interstate transport requirements, among other things, for the 2008 ozone NAAQS. EPA has determined that Delaware's SIP has adequate provisions to prohibit the state from significantly contributing to nonattainment, or interfering with maintenance, of the 2008 ozone NAAQS in any other state. EPA is approving Delaware's SIP revision submittal in regards to the good neighbor interstate transport provision in accordance with the requirements 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/2017/09/27/2017-20598.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"82 FR 44932","comment_url":null,"comments_close_on":"2017-10-27","correction_of":null,"corrections":[],"dates":"This rule is effective on December 26, 2017 without further notice, unless EPA receives adverse written comment by October 27, 2017.
