Record of Decision for the Remediation of the Moab Uranium Mill Tailings, Grand and San Juan Counties, UT

Краткое содержание

The U.S. Department of Energy (DOE) announces its decision to implement the preferred alternatives identified in the Remediation of the Moab Uranium Mill Tailings, Grand and San Juan Counties, Utah, Final Environmental Impact Statement (DOE/EIS-0355) (Final EIS). By implementing the preferred alternatives, DOE will remove the uranium mill tailings and other contaminated material from the Moab milling site and nearby off-site properties (vicinity properties) and relocate them at the Crescent Junction site, using predominantly rail transportation. DOE will also implement active ground water remediation at the Moab milling site. In reaching this decision, DOE considered the potential environmental impacts, costs, and other implications of both on-site and off-site disposal. For off-site disposal, DOE considered three alternative sites in Utah (Crescent Junction, Klondike Flats, and the White Mesa Mill) and three transportation modes (truck, rail, and slurry pipeline). DOE identified off-site disposal as its preferred alternative for the disposal of mill tailings, primarily because of the uncertainties related to long-term performance of a capped pile at the Moab site. Issues, such as
