{"abstract":"Pursuant to section 1424(e) of the Safe Drinking Water Act, the Regional Administrator of the U.S. Environmental Protection Agency (EPA) in Region VIII has determined that the Western Uinta Arch Paleozoic Aquifer System at Oakley, Utah and the immediately adjacent recharge area is the sole or principal source of drinking water for the region. The region is located in central Utah extending from near the City of Oakley, Utah east encompassing approximately 23,000 acres in Townships 1 South and 1 North and Ranges 6 to 8 East SLB&M. The area is irregularly shaped with maximum dimensions of about 14 miles from southwest to northeast and approximately 3 miles from northwest to southeast. The entire area is within Summit County, Utah. No viable alternative sources of drinking water with sufficient supply exist. If this aquifer is contaminated, a significant hazard to public health would occur. The boundaries of the designated area have been reviewed and approved by EPA. As a result of this action, federal financially assisted projects constructed in the approximately 40 square mile area mentioned above will be subject to EPA review to ensure that these projects are designed and constructed in a manner which does not create a significant hazard to public health. For the purposes of this designation the Aquifer Service Area and the Project Review Area are the same as the Designated Area.","action":"Notice of final determination.","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/2000/12/01/00-30634.html","cfr_references":[],"citation":"65 FR 75285","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This determination shall be promulgated for purposes of judicial review at 1:00 p.m. Mountain Standard Time on December 1, 2000.","disposition_notes":null,"docket_ids":["FRL-6900-9"],"dockets":[],"document_number":"00-30634","effective_on":null,"end_page":75287,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2000/12/01/00-30634.xml","html_url":"https://www.federalregister.gov/documents/2000/12/01/00-30634/sole-source-aquifer-determination-for-western-uinta-arch-paleozoic-aquifer-system-oakley-ut","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/00-30634?publication_date=2000-12-01","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2000-12-01/00-30634/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":558,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2000-12-01/pdf/00-30634.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2000-12-01","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2000/12/01/00-30634.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":75285,"subtype":null,"title":"Sole Source Aquifer Determination for Western Uinta Arch Paleozoic Aquifer System, Oakley, UT","toc_doc":"Western Uninta Arch Paleozoic Aquifer System, Oakley, UT","toc_subject":"Water pollution control:","topics":[],"type":"Notice","volume":65}
