{"abstract":"The Agency is proposing to revise the existing regulations regarding Safe Drinking Water Act variances and exemptions. These revisions are based on the 1996 Safe Drinking Water Act Amendments. A new subpart, Subpart K, created to implement a new section in the Amendments, describes procedures and conditions under which a primacy State/Tribe (please note that throughout this preamble and proposed rule, the term ``State'' has the same definition as currently exists in 40 CFR 141.2, i.e., ``State means the agency of the State or Tribal government which has jurisdiction over public water systems . . .'') or the Administrator may issue small system variances to public water systems serving less than 10,000 persons. This rule-making is intended to provide regulatory relief to all public water systems, particularly small systems.","action":"Proposed 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/1998/04/20/98-10393.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"142","title":40}],"citation":"63 FR 19438","comment_url":null,"comments_close_on":"1998-05-20","correction_of":null,"corrections":[],"dates":"Written comments must be received by midnight May 20, 1998.","disposition_notes":null,"docket_ids":["FRL-5999-5"],"dockets":[],"document_number":"98-10393","effective_on":null,"end_page":19457,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1998/04/20/98-10393/revision-of-existing-variance-and-exemption-regulations-to-comply-with-requirements-of-the-safe","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/98-10393?publication_date=1998-04-20","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1998-04-20/98-10393/mods.xml","not_received_for_publication":null,"page_length":20,"page_views":{"count":50,"last_updated":"2026-10-22 20:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1998-04-20/pdf/98-10393.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1998-04-20","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1998/04/20/98-10393.txt","regulation_id_number_info":{"2020-AA37":{"issue":"199804","html_url":"https://www.federalregister.gov/regulations/2020-AA37/revision-of-existing-variances-and-exemptions-regulation-to-comply-with-requirements-of-the-safe-dri","title":"Revision of Existing Variances and Exemptions Regulation to Comply with Requirements of the Safe Drinking Water Act","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=199804&RIN=2020-AA37&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["2020-AA37"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-09-21T03:35:49Z"},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":19438,"subtype":null,"title":"Revision of Existing Variance and Exemption Regulations to Comply With Requirements of the Safe Drinking Water Act","toc_doc":null,"toc_subject":null,"topics":[],"type":"Proposed Rule","volume":63}
