{"abstract":"The EPA is approving the removal of the State rule controlling fluoride emission limitations from existing primary aluminum plants as a revision to the plan for control of fluoride emissions from existing primary aluminum plants (plan), as requested by the State of Indiana on October 17, 2002, and January 22, 2003. Indiana has replaced this rule with another regulation which incorporates by reference current Federal requirements into the Indiana Administrative Code. The rule being removed applies to a single source, Aluminum Company of America (ALCOA), located in Warrick County. Because ALCOA remains subject to more stringent Federal requirements, EPA approval should not result in an adverse impact on air quality.","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/2003/03/11/03-5741.html","cfr_references":[{"chapter":null,"citation_url":null,"part":62,"title":40}],"citation":"68 FR 11472","comment_url":null,"comments_close_on":"2003-04-10","correction_of":null,"corrections":[],"dates":"This direct final rule is effective on May 12, 2003, without further notice unless EPA receives adverse written comments by April 10, 2003.
