{"abstract":"The Safe Drinking Water Act (SDWA), as amended in 1996, requires the United States Environmental Protection Agency (EPA) to periodically publish a list of unregulated contaminants (known as the Contaminant Candidate List or CCL) and determine whether to regulate at least five contaminants on each list. Today's action announces the Agency's final determinations on whether to issue national primary drinking water regulations (NPDWRs) for 11 contaminants listed on the second Contaminant Candidate List (CCL 2). On May 1, 2007, EPA published preliminary regulatory determinations for 11 of the 51 contaminants listed on CCL 2 and requested public comment on the determinations, process, rationale, and supporting technical information for each contaminant. The 11 regulatory determination contaminants are boron; the dacthal mono- and di-acid degradates; 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (DDE); 1,3- dichloropropene; 2,4-dinitrotoluene; 2,6-dinitrotoluene; s-ethyl dipropylthiocarbamate (EPTC); fonofos; terbacil; and 1,1,2,2- tetrachloroethane. In the May 2007 notice, the Agency made a preliminary determination that no regulatory action was appropriate for any of these 11 contaminants. EPA received comments from nine individuals or organizations on the preliminary regulatory determinations for the 11 contaminants and additional comments for other contaminants on CCL 2: perchlorate, methyl tertiary butyl ether (MTBE), metolachlor, and cyanotoxins. After careful review and consideration of these comments, the Agency is making a final determination that no regulatory action is appropriate at this time for any of the 11 CCL 2 contaminants for which the Agency made preliminary regulatory determinations in the May 2007 notice.","action":"Notice.","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/2008/07/30/E8-17463.html","cfr_references":[],"citation":"73 FR 44251","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"For purposes of judicial review, the regulatory determinations in this notice are issued as of July 30, 2008, as provided in 40 CFR 23.7.","disposition_notes":null,"docket_ids":["EPA-HQ-OW-2007-0068","FRL-8699-1"],"dockets":[],"document_number":"E8-17463","effective_on":null,"end_page":44261,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2008/07/30/E8-17463.xml","html_url":"https://www.federalregister.gov/documents/2008/07/30/E8-17463/drinking-water-regulatory-determinations-regarding-contaminants-on-the-second-drinking-water","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E8-17463?publication_date=2008-07-30","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2008-07-30/E8-17463/mods.xml","not_received_for_publication":null,"page_length":11,"page_views":{"count":1102,"last_updated":"2026-10-24 20:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2008-07-30/pdf/E8-17463.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2008-07-30","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2008/07/30/E8-17463.txt","regulation_id_number_info":{"2040-AE60":{"issue":"200804","html_url":"https://www.federalregister.gov/regulations/2040-AE60/drinking-water-regulatory-determinations-regarding-contaminants-on-the-second-drinking-water-contami","title":"Drinking Water: Regulatory Determinations Regarding Contaminants on the Second Drinking Water Contaminant Candidate List","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200804&RIN=2040-AE60&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["2040-AE60"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-11-14T14:22:54Z"},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":44251,"subtype":null,"title":"Drinking Water: Regulatory Determinations Regarding Contaminants on the Second Drinking Water Contaminant Candidate List","toc_doc":"Regulatory Determinations Regarding Contaminants on the Second Drinking Water Contaminant Candidate List","toc_subject":"Drinking Water:","topics":[],"type":"Notice","volume":73}
