{"abstract":"The Environmental Protection Agency (\"EPA\" or \"the Agency\") is today promulgating amendments to the regulations governing Corrective Action Management Units. Corrective Action Management Units, or \"CAMUs,\" are special units created under the Resource Conservation and Recovery Act (RCRA) to facilitate treatment, storage, and disposal of hazardous wastes managed for implementing cleanup, and to remove the disincentives to cleanup that the application of RCRA to these wastes can sometimes impose. The original CAMU regulations were promulgated on February 16, 1993. In today's action, EPA is amending the 1993 CAMU rule in six ways. First, EPA is establishing a specific definition, distinct from the definition of remediation waste, to govern the types of wastes that are eligible for placement in CAMUs. Second, the Agency is establishing more detailed minimum design and operating standards for CAMUs in which waste will remain after closure, with opportunities for Regional Administrators to approve alternate design standards under certain circumstances. Third, the Agency is establishing treatment requirements for wastes that are placed in CAMUs, including minimum treatment standards, with opportunities to adjust treatment requirements under certain circumstances. Fourth, EPA is establishing more specific information requirements for CAMU applications and is explicitly requiring that the public be given notice and a reasonable opportunity for public comment before final CAMU determinations are made. Fifth, the Agency is establishing new requirements for CAMUs that will be used only for treatment and storage. Sixth, today's rulemaking \"grandfathers\" certain types of existing CAMUs and allows them to continue to operate under the 1993 rule. Today's rulemaking amends the regulations for \"staging piles\" to expressly allow for mixing, blending, and other similar physical operations intended to prepare wastes for subsequent management or treatment. It also adds a new provision allowing off-site placement of hazardous CAMU-eligible waste in hazardous waste landfills, if they are treated to meet CAMU treatment standards (somewhat modified). Finally, today's rule grants interim authorization for these CAMU amendments to states that are authorized for the 1993 CAMU rule, and it expedites state authorization for the CAMU rule for states that are authorized for the RCRA corrective action program but not the 1993 CAMU rule. Today's amendments were proposed on August 22, 2000, referred to throughout this rulemaking as \"the proposal.\" EPA also proposed a supplemental proposal on November 20, 2001, referred to as \"the supplemental proposal.\"","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/2002/01/22/02-4.html","cfr_references":[{"chapter":null,"citation_url":null,"part":260,"title":40},{"chapter":null,"citation_url":null,"part":264,"title":40},{"chapter":null,"citation_url":null,"part":271,"title":40}],"citation":"67 FR 2962","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective April 22, 2002.","disposition_notes":null,"docket_ids":["FRL-7124-3"],"dockets":[],"document_number":"02-4","effective_on":"2002-04-22","end_page":3029,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2002/01/22/02-4.xml","html_url":"https://www.federalregister.gov/documents/2002/01/22/02-4/amendments-to-the-corrective-action-management-unit-rule","images":{"ER22JA02.003":{"large":"https://img.federalregister.gov/ER22JA02.003/ER22JA02.003_large.png","medium":"https://img.federalregister.gov/ER22JA02.003/ER22JA02.003_medium.png","original_size":"https://img.federalregister.gov/ER22JA02.003/ER22JA02.003_original_size.png"}},"images_metadata":{"ER22JA02.003":{"large":{"identifier":"ER22JA02.003","content_type":"image/png","size":5116,"width":764,"sha":"9c3b90cb656f0112e091e386393acee4","url":"https://img.federalregister.gov/ER22JA02.003/ER22JA02.003_large.png","height":61},"medium":{"identifier":"ER22JA02.003","content_type":"image/png","size":1786,"width":360,"sha":"3523b70a22893cc4a14f96ac36c2817c","url":"https://img.federalregister.gov/ER22JA02.003/ER22JA02.003_medium.png","height":29},"original_size":{"identifier":"ER22JA02.003","content_type":"image/png","size":1243,"width":326,"sha":"94dc3d660f2a899a539bfd10d0b298db","url":"https://img.federalregister.gov/ER22JA02.003/ER22JA02.003_original_size.png","height":26}}},"json_url":"https://www.federalregister.gov/api/v1/documents/02-4?publication_date=2002-01-22","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2002-01-22/02-4/mods.xml","not_received_for_publication":null,"page_length":68,"page_views":{"count":1031,"last_updated":"2026-07-26 04:15:02 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2002-01-22/pdf/02-4.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2002-01-22","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2002/01/22/02-4.txt","regulation_id_number_info":{"2050-AE77":{"issue":"200110","html_url":"https://www.federalregister.gov/regulations/2050-AE77/amendments-to-the-corrective-action-management-unit-rule","title":"Amendments to the Corrective Action Management Unit Rule","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200110&RIN=2050-AE77&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["2050-AE77"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":2962,"subtype":null,"title":"Amendments to the Corrective Action Management Unit Rule","toc_doc":"Corrective Action Management Units","toc_subject":"Hazardous waste:","topics":["Administrative practice and procedure","Air pollution control","Confidential business information","Environmental protection","Hazardous materials transportation","Hazardous waste","Indians-lands","Insurance","Intergovernmental relations","Packaging and containers","Penalties","Reporting and recordkeeping requirements","Security measures","Surety bonds","Water pollution control","Water supply"],"type":"Rule","volume":67}
