Title: Transportation of the MOAB Uranium Mill Tailings to White Mesa Mill by Slurry Pipeline

Abstract

The Moab uranium mill tailings pile, located at the former Atlas Minerals Corporation site approximately three miles north of Moab, Utah, is now under the control of the US Department of Energy (''DOE''). The location of the tailings pile adjacent to the Colorado River, and the ongoing contamination of groundwater and seepage of pollutants into the river, have lead to the investigation, as part of the final site remediation program, of alternatives to relocate the tailings to a qualified permanent disposal site. This paper will describe the approach being taken by the team formed between International Uranium (USA) Corporation (''IUC'') and Washington Group International (''WGINT'') to develop an innovative technical proposal to relocate the Moab tailings to IUC's White Mesa Mill south of Blanding, Utah. The proposed approach for relocating the tailings involves using a slurry pipeline to transport the tailings to the White Mesa Mill. The White Mesa Mill is a fully licensed, active uranium mill site that is uniquely suited for permanent disposal of the Moab tailings. The tailings slurry would be dewatered at the White Mesa Mill, the slurry water would be recycled to the Moab site for reuse in slurry makeup, and the ''dry'' tailings wouldmore » be permanently disposed of in an approved below grade cell at the mill site.« less

  • The U.S. Department of Energy (DOE or the Department) is proposing to clean up surface contamination and implement a ground water compliance strategy to address contamination that resulted from historical uranium-ore processing at the Moab Uranium Mill Tailings Site (Moab site), Grand County, Utah. Pursuant to the National Environmental Policy Act (NEPA), 42 United States Code (U.S.C.) {section} 4321 et seq., DOE prepared this environmental impact statement (EIS) to assess the potential environmental impacts of remediating the Moab site and vicinity properties (properties where uranium mill tailings were used as construction or fill material before the potential hazards associated withmore » the tailings were known). DOE analyzed the potential environmental impacts of both on-site and off-site remediation and disposal alternatives involving both surface and ground water contamination. DOE also analyzed the No Action alternative as required by NEPA implementing regulations promulgated by the Council on Environmental Quality. DOE has determined that its preferred alternatives are the off-site disposal of the Moab uranium mill tailings pile, combined with active ground water remediation at the Moab site. The preferred off-site disposal location is the Crescent Junction site, and the preferred method of transportation is rail. The basis for this determination is discussed later in this Summary. DOE has entered into agreements with 12 federal, tribal, state, and local agencies to be cooperating agencies in the development and preparation of this EIS. Several of the cooperating agencies have jurisdiction by law and intend to use the EIS to support their own decisionmaking. The others have expertise relevant to potential environmental, social, or economic impacts within their geographic regions. During the preparation of the EIS, DOE met with the cooperating agencies, provided them with opportunities to review preliminary versions of the document, and addressed their comments and concerns to the fullest extent possible. DOE received over 1,600 comments on the draft EIS from the public, federal, state and local agencies, tribes, governors, and members of Congress. DOE has considered these comments in finalizing the EIS and has provided responses to all comments in the EIS.« less
  • This paper introduced a new idea of transporting mine tailings-logs in mine tailings-slurry pipeline and a new technology of mine cemented filing of tailings-logs with tailings-slurry. The hydraulic principles, the compaction of tailings-logs and the mechanic function of fillbody of tailings-logs cemented by tailings-slurry have been discussed.
  • The project described in this report was conducted by personnel from Oak Ridge National Laboratory's Grand Junction Office (ORNL/GJ). This report has been prepared as a companion report to the Limited Groundwater Investigation of the Atlas Corporation Moab Mill, Moab, Utah. The purpose of this report is to present the results of the tailings pile seepage modeling effort tasked by the U.S. Nuclear Regulatory Commission (NRC).
  • The initial phase of this investigation has determined that there is a twofold excess of leukemia incidence for all ages in Mesa County, Colorado, for the period 1970 to 1976. The greatest excess was observed among residents over 65 years of age who developed leukemia 2-1/2 times the expected rate. No excess incidence of lung cancer has been identified. The second phase of the investigation has been case-control study of all adult leukemia deaths since 1960. No significant differences were found beween cases and controls with respect to: years of residence in Mesa Couty, general health status prior to diagnosis,more » and radiation exposure from tailings buildings. Only two cases and two controls had ever lived in houses with elevated gamma radiation from uranium mill tailings used in construction. Only one case and one control has a cumulative and average annual exposure significantly higher than the other subjects. Leukemia cases had higher socioeconomic levels and more positive family histories of leukemia than controls. No association between tailings structures and leukemia excess was observed.« less
  • Water quality simulation of the black mesa coal slurry Pipeline System was carried out using specially designed laboratory techniques. Excellent correlation was obtained between actual and simulated water quality characteristics, proving the success of the methods employed. The techniques provide a useful tool for forecasting waste water characteristics, for obtaining discharge permits and design of treatment facilities for slurry pipelines in general.
