{"abstract":"On April 11, 2002, pursuant to section 112 of the Clean Air Act (CAA), the EPA issued national emission standards to control hazardous air pollutants emitted from catalytic cracking units, catalytic reforming units, and sulfur recovery units at petroleum refineries. This action promulgates amendments to several sections of the existing standards. The amendments will change the affected source designations and add new compliance options for catalytic reforming units that use different types of emission control systems, new monitoring alternatives for catalytic cracking units and catalytic reforming units, and a new procedure for determining the metal or total chloride concentration on catalyst particles. The amendments will also defer technical requirements for most continuous parameter monitoring systems, clarify testing and monitoring requirements, and make editorial corrections.","action":"Direct final rule; amendments.","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/2005/02/09/05-2308.html","cfr_references":[{"chapter":null,"citation_url":null,"part":63,"title":40}],"citation":"70 FR 6930","comment_url":null,"comments_close_on":"2005-03-28","correction_of":null,"corrections":[],"dates":"The final amendments will be effective on April 11, 2005, unless we receive significant adverse comments by March 11, 2005, or by March 28, 2005 if a public hearing is requested.
