This 8 supplements the U.S. Department of Energy’s (DOE’s) 2002 “Final Environmental Impact 9 Statement for a Geologic Repository for the Disposal of Spent Nuclear Fuel and High-Level 10 Radioactive Waste at Yucca Mountain, Nye County, Nevada” and 2008 “Final Supplemental 11 Environmental Impact Statement for a Geologic Repository for the Disposal of Spent Nuclear 12 Fuel and High-Level Radioactive Waste at Yucca Mountain, Nye County, Nevada,” in 13 accordance with the findings and scope outlined in the U.S. Nuclear Regulatory Commission 14 (NRC) staff’s 2008 “Adoption Determination Report for the U.S. Department of Energy’s 15 Environmental Impact Statements for the Proposed Geologic Repository at Yucca Mountain.” 16 This supplement describes the affected environment and assesses the potential environmental 17 impacts with respect to potential contaminant releases from the repository that could be 18 transported through the volcanic-alluvial aquifer in Fortymile Wash and the Amargosa Desert, 19 and to the Furnace Creek/Middle Basin area of Death Valley. This supplement evaluates the 20 potential radiological and nonradiological impacts—over a one million year period—on the 21 aquifer environment, soils, ecology, and public health, as well as the potential for 22 disproportionate impacts on minority or low-income populations. In addition, this supplement 23 assesses the potential for cumulative impacts associated with other past, present, or reasonably 24 foreseeable future actions. The NRC staff finds that all of the potential direct, indirect, and 25 cumulative impacts on the resources evaluated in this supplement would be SMALL. iii 1 CONTENTS 2 Section Page 3 ABSTRACT ................................................................................................................................... iii 4 FIGURES ..................................................................................................................................... vii 5 TABLES ....................................................................................................................................... ix 6 EXECUTIVE SUMMARY ............................................................................................................. xi 7 ACRONYMS AND ABBREVIATIONS ......................................................................................... xiii 8 1 INTRODUCTION ............................................................................................................ 1-1 9 1.1 Background—License Application and EIS Adoption Review Process .............. 1-1 10 1.2 Scope and Assumptions ....................................................................................
