{"abstract":"This action finalizes amendments to national emission standards for hazardous air pollutants (NESHAP) for hydrochloric acid (HCl) production facilities, including HCl production at fume silica facilities. The amendments to the final rule clarify certain applicability provisions, emission standards, and testing, maintenance, and reporting requirements. The amendments also correct several omissions and typographical errors in the final rule. We are finalizing the amendments to facilitate compliance and improve understanding of the final rule requirements.","action":"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/2006/04/07/06-3309.html","cfr_references":[{"chapter":null,"citation_url":null,"part":63,"title":40}],"citation":"71 FR 17738","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The final rule is effective April 7, 2006.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2002-0057","FRL-8055-6"],"dockets":[],"document_number":"06-3309","effective_on":"2006-04-07","end_page":17750,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2006/04/07/06-3309.xml","html_url":"https://www.federalregister.gov/documents/2006/04/07/06-3309/national-emission-standards-for-hazardous-air-pollutants-hydrochloric-acid-production","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/06-3309?publication_date=2006-04-07","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2006-04-07/06-3309/mods.xml","not_received_for_publication":null,"page_length":13,"page_views":{"count":195,"last_updated":"2026-10-24 10:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2006-04-07/pdf/06-3309.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2006-04-07","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2006/04/07/06-3309.txt","regulation_id_number_info":{"2060-AM25":{"issue":"200404","html_url":"https://www.federalregister.gov/regulations/2060-AM25/neshap-hydrochloric-acid-production-amendments","title":"NESHAP: Hydrochloric Acid Production Amendments","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200404&RIN=2060-AM25&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2060-AM25"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Information Collection Request for National Emissions Standards for Hazardous Air Pollutants from Hydrochloric Acid Production, (EPA ICR #2032.02).
