C -- TRENCH 1 REMEDIATION, STABILIZATION OF DEPLETED URANIUM SOL RM-SS-01 DUE 062397 POC Technical: Mark Burmeister (303)966-5891 or Procurement: Tom Vetack (303)966-8170 The Environmental Restoration Division of Rocky Mountain Remediation Services, L.L.C. (RMRS) is the planning phases of the Trench T-1 (T-1) remediation project at the U.S. Department of Energy's Rocky Flats Environmental Technology Site (RFETS), located northwest of Denver, Colorado. As part of a market survey to gain technical information of the services and equipment available, RMRS is soliciting qualifications and relevant experience from interested parties for the proposed Trench T-1 activities. Trench T-1 is expected to contain as many as 125 drums (25,000 kg) depleted uranium (DU) machine turnings/chips that were originally packed in a water-based lathe coolant. An additional 1,000-1,500 cubic yards of soil and debris, potentially impacted with radionuclides, is anticipated to be excavated and possibly treated. The chips and debris were intermittently placed in the trench from 1954 to 1962. It is proposed that the drummed chips, and a portion of the soil and debris be excavated, treated on-site by encapsulation, and packaged for proper transportation and off-site disposal as low-level radioactive waste. It is possible that some of the drums have degraded over time and lost a portion of the lathe coolant originally covering the DU chips. Chips may be partially oxidized. Due to the potential pyrophoric nature of the DU chips, the drummed waste and possibly a portion of the soil and debris, will require on-site stabilization to prevent contact with oxygen and moisture. Additional information can be found in the Draft Proposed Action Memorandum for the Source Removal at Trench 1, IHSS 108, (RMRS, 1997), currently out for public comment. Interested parties should forward information of their design and implementation capabilities which may be applicable for the T-1 remedial action. This information may include, but not be limited to, technical specifications, treatability studies, process design and flow sheets, field operations, and previous experience in stabilitization of pyrophoric radioactive materials. Due to the nature of the work, RMRS is interested in developed and proven technologies for performing the T-1 remediation and achieving waste acceptance criteria for disposal at low-level radioactive waste facilities. Demonstrated experience of DOE/EPA/DOE/OSHA regulations, compliance, and managemment of hazardous and radioactive wastes is necessary. All submittals must be received no later than 4:30 P.M., MST, June 23, 1997. Please submit responses and questions to Rocky Mountain Remediation Services, L.L.C., Rocky Flats Environmental Technology Site, P.O.
