{"abstract":"The Environmental Protection Agency (EPA) announces the release of final Recommended Human Health Recreational Ambient Water Quality Criteria or Swimming Advisories for Microcystins and Cylindrospermopsin. These are the recommended concentrations of the cyanotoxins microcystins and cylindrospermopsin in recreational waters protective of human health while swimming or participating in primary contact recreational activities on the water. The recommended values found in this document supplement the 2012 Recreational Water Quality Criteria to provide further public health protection for potentially hazardous conditions found in ambient recreational waters. This document was released for 90-day public comment in the Federal Register on December 16, 2016. The EPA has considered the comments, revised the draft document, as appropriate, and published this final document to provide recommendations for states and authorized tribes interested in establishing water quality standards (WQS) under the Clean Water Act (CWA). Alternatively, these same values can be used as the basis for swimming advisories in recreational waters to protect the public. States and authorized tribes may also wish to consider using these values as both WQS and swimming advisory values.","action":"Notice of availability.","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/2019/06/06/2019-11814.html","cfr_references":[],"citation":"84 FR 26413","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":null,"disposition_notes":null,"docket_ids":["EPA-HQ-OW-2016-0715","FRL-9994-58-OW"],"dockets":[],"document_number":"2019-11814","effective_on":null,"end_page":26414,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2019/06/06/2019-11814.xml","html_url":"https://www.federalregister.gov/documents/2019/06/06/2019-11814/recommended-human-health-recreational-ambient-water-quality-criteria-or-swimming-advisories-for","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2019-11814?publication_date=2019-06-06","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2019-06-06/2019-11814/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":4464,"last_updated":"2026-10-22 14:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2019-06-06/pdf/2019-11814.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2019-11814.pdf?1559738722","publication_date":"2019-06-06","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2019/06/06/2019-11814.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Draft Human Health Recreational Ambient Water Quality Criteria and/or Swimming Advisories for Microcystins and Cylindrospermopsin","document_id":"EPA-HQ-OW-2016-0715-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-HQ-OW-2016-0715","supporting_documents_count":1,"docket_id":"EPA-HQ-OW-2016-0715","regulation_id_number":null,"title":"Human Health Recreational Ambient Water Quality Criteria and/or Swimming Advisories for Microcystins and Cylindrospermopsin","checked_regulationsdotgov_at":"2019-06-12T05:52:26Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":26413,"subtype":null,"title":"Recommended Human Health Recreational Ambient Water Quality Criteria or Swimming Advisories for Microcystins and Cylindrospermopsin","toc_doc":"Recommended Human Health Recreational Ambient Water Quality Criteria or Swimming Advisories for Microcystins and Cylindrospermopsin","toc_subject":null,"topics":[],"type":"Notice","volume":84}
