{"abstract":"EPA updates test methods and waste sampling guidance as part of routine updates according to the Resource Conservation and Recovery Act (RCRA). To aid in the implementation of these directives, the Office of Resource Conservation and Recovery (ORCR) within the Environmental Protection Agency (EPA) requests information on SW-846 method experiences, needs, and requirements. ORCR is specifically interested in information on the Toxicity Characteristic Leaching Procedure (TCLP) Method 1311, including method challenges, and alternatives. Information is welcome from stakeholders involved in requesting, performing, and evaluating the results from SW-846 methods including, but not limited to, industry stakeholders, researchers, academia, state, Tribal, and local governments. This includes U.S. territories and the District of Columbia, other federal agencies, community groups, non-governmental organizations, the public, and international organizations. The EPA will use the information received in response to this request for information (RFI) to inform what action, if any, it may take.","action":"Notice; request for information.","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/2026/09/14/2026-18754.html","cfr_references":[],"citation":"91 FR 58117","comment_url":"http://www.regulations.gov/commenton/EPA-HQ-OLEM-2026-7360-0001","comments_close_on":"2026-11-13","correction_of":null,"corrections":[],"dates":"Comments and information must be received on or before November 13, 2026 to allow for consideration in any short-term updates to the methods.
