{"abstract":"The EPA is establishing a new Federal Reference Method (FRM) for measuring Lead (Pb) in total suspended particulate matter (TSP) collected from ambient air. This method is intended for use by analytical laboratories performing the analysis of Pb in TSP to support data collection for the Pb National Ambient Air Quality Standard (NAAQS). The existing FRM for Pb is designated as a new Federal Equivalent Method (FEM), and the currently designated FEMs are retained. This action avoids any disruption to existing Pb monitoring networks and data collection and does not affect the FRM for TSP sample collection (High-Volume Method).","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/2013/07/03/2013-15880.html","cfr_references":[{"chapter":null,"citation_url":null,"part":50,"title":40}],"citation":"78 FR 40000","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective on August 2, 2013.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2012-0210","FRL-9822-1"],"dockets":[],"document_number":"2013-15880","effective_on":"2013-08-02","end_page":40011,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2013/07/03/2013-15880.xml","html_url":"https://www.federalregister.gov/documents/2013/07/03/2013-15880/method-for-the-determination-of-lead-in-total-suspended-particulate-matter","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2013-15880?publication_date=2013-07-03","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2013-07-03/2013-15880/mods.xml","not_received_for_publication":null,"page_length":12,"page_views":{"count":2390,"last_updated":"2026-07-28 10:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2013-07-03/pdf/2013-15880.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2013-15880.pdf?1372769321","publication_date":"2013-07-03","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2013/07/03/2013-15880.txt","regulation_id_number_info":{"2060-AP89":{"issue":"201304","html_url":"https://www.federalregister.gov/regulations/2060-AP89/federal-reference-method-for-lead-in-total-suspended-particulate-matter","title":"Federal Reference Method for Lead in Total Suspended Particulate Matter","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201304&RIN=2060-AP89&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2060-AP89"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Results from the Development of a New FRM for Lead in TSP Matter","document_id":"EPA-HQ-OAR-2012-0210-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2060-AP89/federal-reference-method-for-lead-in-total-suspended-particulate-matter","title":"Federal Reference Method for Lead in Total Suspended Particulate Matter"},"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-HQ-OAR-2012-0210","supporting_documents_count":1,"docket_id":"EPA-HQ-OAR-2012-0210","regulation_id_number":"2060-AP89","title":"Federal Reference Method for Lead in Total Suspended Particulate Matter","checked_regulationsdotgov_at":"2013-07-23T08:11:27Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":40000,"subtype":null,"title":"Method for the Determination of Lead in Total Suspended Particulate Matter","toc_doc":"Method for the Determination of Lead in Total Suspended Particulate Matter","toc_subject":null,"topics":["Air pollution control","Environmental protection","Lead"],"type":"Rule","volume":78}
