{"abstract":"The U.S. Nuclear Regulatory Commission (NRC) is issuing an environmental assessment (EA) and finding of no significant impact (FONSI) for an exemption requested by SMR, LLC on behalf of Palisades SMR, LLC (Palisades SMR), associated with certain excavation support activities for the proposed dual-unit SMR-300 plant, Pioneer Units 1 and 2, at the Palisades Energy Center in Covert, Michigan. Specifically, Palisades SMR is requesting an exemption, pursuant to NRC regulations, to allow for construction of support of excavation (SOE) walls during SMR-300 excavation and prior to issuance of a Limited Work Authorization (LWA), if approved. Based on the analyses presented in the EA, the NRC staff determined that there would be no significant environmental impacts associated with granting the requested exemption.","action":"Notice; issuance.","agencies":[{"raw_name":"NUCLEAR REGULATORY COMMISSION","name":"Nuclear Regulatory Commission","id":383,"url":"https://www.federalregister.gov/agencies/nuclear-regulatory-commission","json_url":"https://www.federalregister.gov/api/v1/agencies/383","parent_id":null,"slug":"nuclear-regulatory-commission"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/08/25/2026-17253.html","cfr_references":[],"citation":"91 FR 54890","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The EA and FONSI referenced in this document are available on August 24, 2026.","disposition_notes":null,"docket_ids":["Docket Nos. 050-616 and 050-617","NRC-2026-0265"],"dockets":[{"supporting_documents":[],"agency_name":"NRC","documents":[{"comment_count":0,"comment_start_date":"2026-08-25","updated_at":"2026-08-25T09:57:30.764-04:00","comment_url":"https://www.regulations.gov/commenton/NRC-2026-0265-0010","allow_late_comments":false,"id":"NRC-2026-0265-0010","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"NRC-2026-0265","title":"SMR, LLC Pioneer Units 1 and 2 Limited Work Authorization Application"}],"document_number":"2026-17253","effective_on":null,"end_page":54892,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/08/25/2026-17253.xml","html_url":"https://www.federalregister.gov/documents/2026/08/25/2026-17253/smr-llc-palisades-smr-llc-pioneer-units-1-and-2-environmental-assessment-and-finding-of-no","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-17253?publication_date=2026-08-25","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-08-25/2026-17253/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":238,"last_updated":"2026-10-24 10:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-08-25/pdf/2026-17253.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-17253.pdf?1787575514","publication_date":"2026-08-25","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/08/25/2026-17253.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[],"comments_count":0,"agency_id":"NRC","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=NRC-2026-0265","supporting_documents_count":0,"docket_id":"NRC-2026-0265","document_id":"NRC-2026-0265-0010","regulation_id_number":null,"title":"SMR, LLC Pioneer Units 1 and 2 Limited Work Authorization Application","checked_regulationsdotgov_at":"2026-08-26T15:55:06Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":54890,"subtype":null,"title":"SMR, LLC; Palisades SMR, LLC; Pioneer Units 1 and 2; Environmental Assessment and Finding of No Significant Impact","toc_doc":"SMR, LLC; Palisades SMR, LLC; Pioneer Units 1 and 2","toc_subject":"Environmental Assessments; Availability, etc.","topics":[],"type":"Notice","volume":91}
