{"abstract":"This final action deletes the subcategory of sources that do not utilize mercury cells to produce chlorine and caustic. We have determined that this non-mercury cell chlorine production subcategory should be deleted because chlorine and hydrochloric acid (HCl), the only hazardous air pollutants (HAP) emitted, are not carcinogenic, have well-defined health thresholds, and chlorine and HCl air emissions from each non-mercury cell chlorine subcategory source do not exceed a level which is adequate to protect public health with an ample margin of safety. In addition, the emissions of chlorine and HCl will not result in any adverse environmental effects. This final action does not address chlorine and HCl emissions from mercury cell chlor-alkali plants. The final rulemaking for the mercury cell chlor-alkali plant subcategory is contained elsewhere in this issue of the Federal Register.","action":"Final decision to delete subcategory.","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/2003/12/19/03-22929.html","cfr_references":[{"chapter":null,"citation_url":null,"part":63,"title":40}],"citation":"68 FR 70948","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"December 19, 2003.","disposition_notes":null,"docket_ids":["OAR-2002-0016, FRL-7554-6"],"dockets":[],"document_number":"03-22929","effective_on":null,"end_page":70957,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2003/12/19/03-22929.xml","html_url":"https://www.federalregister.gov/documents/2003/12/19/03-22929/national-emission-standards-for-hazardous-air-pollutants-chlorine-and-hydrochloric-acid-emissions","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/03-22929?publication_date=2003-12-19","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2003-12-19/03-22929/mods.xml","not_received_for_publication":null,"page_length":10,"page_views":{"count":906,"last_updated":"2026-10-22 16:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2003-12-19/pdf/03-22929.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2003-12-19","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2003/12/19/03-22929.txt","regulation_id_number_info":{"2060-AK38":{"issue":"200304","html_url":"https://www.federalregister.gov/regulations/2060-AK38/neshap-chlorine-production","title":"NESHAP: Chlorine Production","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200304&RIN=2060-AK38&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2060-AK38"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"S.
