{"abstract":"EPA is adding a hexabromocyclododecane (HBCD) category to the list of toxic chemicals subject to reporting under section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA) and section 6607 of the Pollution Prevention Act (PPA). EPA is adding this chemical category to the EPCRA section 313 list because EPA has determined that HBCD meets the EPCRA section 313(d)(2)(B) and (C) toxicity criteria. Specifically, EPA has determined that HBCD can reasonably be anticipated to cause developmental and reproductive effects in humans and is highly toxic to aquatic and terrestrial organisms. In addition, based on the available bioaccumulation and persistence data, EPA has determined that HBCD should be classified as a persistent, bioaccumulative, and toxic (PBT) chemical and assigned a 100-pound reporting threshold.","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/2016/11/28/2016-28102.html","cfr_references":[{"chapter":null,"citation_url":null,"part":372,"title":40}],"citation":"81 FR 85440","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective Date: This final rule is effective November 30, 2016.","disposition_notes":null,"docket_ids":["EPA-HQ-TRI-2015-0607","FRL-9953-28"],"dockets":[],"document_number":"2016-28102","effective_on":"2016-11-30","end_page":85445,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/11/28/2016-28102.xml","html_url":"https://www.federalregister.gov/documents/2016/11/28/2016-28102/addition-of-hexabromocyclododecane-hbcd-category-community-right-to-know-toxic-chemical-release","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-28102?publication_date=2016-11-28","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-11-28/2016-28102/mods.xml","not_received_for_publication":null,"page_length":6,"page_views":{"count":494,"last_updated":"2026-09-22 22:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-11-28/pdf/2016-28102.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-28102.pdf?1480081528","publication_date":"2016-11-28","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/11/28/2016-28102.txt","regulation_id_number_info":{"2025-AA42":{"issue":"201610","html_url":"https://www.federalregister.gov/regulations/2025-AA42/toxics-release-inventory-addition-of-hexabromocyclododecane-hbcd-","title":"Toxics Release Inventory Addition of Hexabromocyclododecane (HBCD)","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201610&RIN=2025-AA42&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2025-AA42"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Enantioselective Biotransformation of Hexabromocyclododecane by\nin Vitro Rat and Trout Hepatic Sub-Cellular Fractions","document_id":"EPA-HQ-TRI-2015-0607-0215"},{"title":"Exposure Assessment of Fetus And Newborn to Brominated Flame Retardants In France:  Preliminary Data","document_id":"EPA-HQ-TRI-2015-0607-0210"},{"title":"Metabolic Test of Hexabromocyclododecane.
