Submittal of a Long-Term Monitoring and Maintenance Plan for Solid Waste Management Units and Technical and Administrative Corrections and Updates to Comprehensive Part B Permit Request for Sandia National Laboratories/New Mexico, EPA ID Number NM5890110518

1281 pgs.The Department of Energy/National Nuclear Security Administration (DOE/NNSA) and Sandia Corporation (Sandia) submitted a Comprehensive Part B Permit Request to the New Mexico Environment Department in February 2002. The Part B Permit Request included permit applications and permit renewal requests for several hazardous and radioactive/hazardous mixed waste storage and treatment operations at Sandia National Laboratories in Albuquerque, New Mexico (SNL/NM). The Part B Permit Request has been revised numerous times: to address Notices of Deficiency issued by NMED, and to incorporate changes in waste management operations at SNL/NM. DOE and Sandia are submitting technical and administrative corrections and updates at this time. The revised Part B Permit Request is included in its entirety. It addresses operations at the Hazardous Waste Handling Facility, the Thermal Treatment Facility, the Radioactive and Mixed Waste Management Facility, the Auxiliary Hot Cell Facility, five Manzano Storage Bunkers, and the Corrective Action Management Unit. The Part B Permit Request also includes information about solid waste management units (SWMUs) and areas of concern (AOCs) for which corrective action is not complete. DOE/NNSA and Sandia completed corrective action at numerous SWMUs and AOCs at SNL/NM. These SWMUs and AOCs are listed in Table A.2 “List of Solid Waste Management Units (SWMUs) and Areas of Concern (AOCs) Not Currently Requiring Corrective Action” in Module IV of Permit NM5890110518-1. In 2007 and 2008, DOE and Sandia requested that NMED add 31 SWMUs and AOCs to the list in Table A.2. In April 2010, NMED requested additional corrective action and information at several SWMUs and indicated the final decision regarding completion would be made in conjunction with renewal of the permit for hazardous waste management activities at SNL/NM. DOE and Sandia submitted a long-term monitoring and maintenance plan (LTMMP) for selected SWMUs/AOCs listed in Table A.2 and several of the SWMUs/AOCs under review by NMED. There are nine attachments (A-I) included in this document: Attachments A-B – discussion and LTMMP for selected SWMUs and AOCs Attachments C-H – revisions to Part B Permit Request Attachment I – Revised Part B Permit Request (complete)Department of Energy (DOE)and National Nuclear Security Administration (NNSA
