AFFECTED ENVIRONMENT – CALIENTE RAIL ALIGNMENT Figure 3-72. Groundwater usage in Nevada in 2000. (Source: DIRS 175964-Lopes and Evetts 2004, p. 7.) There are a number of published estimates of perennial yield for many of the hydrographic areas in Nevada, and those estimates often differ by large amounts. The perennial-yield values listed in Table 3-35 predominantly come from a single source, the Nevada Division of Water Planning (DIRS 103406-Nevada Division of Water Planning 1992, for Hydrographic Regions 10, 13, and 14); therefore, the table does not show a range of values for each hydrographic area. In the Yucca Mountain area, the Nevada Division of Water Planning identifies a combined perennial yield for hydrographic areas 225 through 230. DOE obtained perennial yields from Data Assessment & Water Rights/Resource Analysis of: Hydrographic Region #14 Death Valley Basin (DIRS 147766-Thiel 1999, pp. 6 to 12) to provide estimates for hydrographic areas the Caliente rail alignment would cross: 227A, 228, and 229. That 1999 document presents perennial-yield estimates from several sources. Table 3-35 lists the lowest (that is, the most conservative) values cited in that document, which is consistent with the approach DOE used in the Yucca Mountain FEIS (DIRS 155970-DOE 2002, p. 3-136). DOE/EIS-0369 3-173 AFFECTED ENVIRONMENT – CALIENTE RAIL ALIGNMENT Table 3-35 also summarizes existing annual committed groundwater resources for each hydrographic area along the Caliente rail alignment. However, all committed groundwater resources within a hydrographic area might not be in use at the same time. Table 3-35 also includes information on pending annual duties within each of these hydrographic areas. -
Structure and Devonian Stratigraphy of the Timpahute Range, Nevada
STRUCTURE AND DEVONIAN STRATIGRAPHY OF THE TIMPAHUTE RANGE, NEVADA Volume I by Alan K. Chamberlain © Copyright, 1999 A thesis submitted to the Faculty and Board of Trustees of the Colorado School of Mines in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Geology). Golden, Colorado Date____________ Signed:__________________________ Alan K. Chamberlain Approved:__________________________ Dr. John E. Warme Professor and Thesis Advisor Golden, Colorado Date____________ ____________________________________ Dr. Roger Slatt, Professor and Head, Department of Geology and Geological Engineering ii ABSTRACT Sequences of Devonian rocks are advantageously exposed along a unique 40- mile-long east-west traverse in the greater Timpahute Range, southeastern Nevada. Study of these rocks casts light upon Devonian paleogeography, the Devonian Antler orogeny, an Upper Devonian cosmolite impact basin, this part of the Cretaceous Sevier fold-and- thrust belt, and the effects of Cenozoic extension. The greater Timpahute Range lies within the Timpahute Range 30' X 60' quadrangle and includes the region from Tempiute Mountain on the west to the Pahroc Range on the east. Concealed major north-south trending normal faults caused by Cenozoic extension have been proposed to disrupt the Paleozoic rocks of the region. However, a structural interpretation using a new geologic map of the quadrangle requires no major north-south striking normal faults. Furthermore, the greater Timpahute Range is interpreted as a salient of stacked thrust sheets within the Sevier fold-and-thrust belt. The range is bounded on the north and south by thrust tear faults that may be related to basement fractures caused by the cosmolite impact. Evidence for the Late Devonian cosmolite impact includes shocked quartz, iridium anomalies, ejecta spherules, and disturbed shallowing-upward sequences exhibiting intrasequence folding, brecciation, carbonate liquefaction, and graded bedding. -
Legislative EIS for the NTTR Land Withdrawal
3-1 OCTOBER 2018 3. AFFECTED ENVIRONMENT AND ENVIRONMENTAL CONSEQUENCES This chapter of the LEIS concisely describes the environmental resources that may be affected by the alternatives, including the Proposed Action, and analyzes the potential impacts to those resources. The analysis in this LEIS is applied in proportion to the importance of the anticipated consequences (e.g., impacts). To ensure the LEIS properly considers substantive issues, the Air Force focused the analysis on important issues commensurate with the importance of anticipated impacts. The Air Force has deemphasized nonsubstantive issues. The affected environment includes all areas and lands that might be affected, to include natural, cultural, and socioeconomic resources they contain or support. As stated in Sections 2.3.2 and 2.3.3, the analysis in this LEIS uses a projected 30 percent increase in test and training activities to provide a reference point for analytical comparisons. Therefore, aircraft operations, munitions expenditures, and motorized vehicular activity were analyzed for Alternatives 2 and 3 at operational tempos 30 percent greater than those levels stated for Alternative 1. The land boundary under Alternative 3 would include the current NTTR boundary as outlined in Section 2.3.1, plus various options for additional lands needed for the operational and safety requirements described in Sections 1.4.1 through 1.4.3. Each of the subalternatives associated with Alternative 3 would require fencing but only on the proposed boundaries that do not abut the current NTTR boundary. The fencing would be constructed to meet BLM fencing requirements, dependent on the topography and wildlife present, as outlined in BLM Handbook H-1741-1: Fencing, and the objective of the fencing would be to provide a physical barrier to prevent public access while allowing wildlife passage. -

Establishment of the Basin and Range National Monument
This document is scheduled to be published in the Federal Register on 07/15/2015 and available online at http://federalregister.gov/a/2015-17549, and on FDsys.gov ESTABLISHMENT OF THE BASIN AND RANGE NATIONAL MONUMENT 9297 - - - - - - - BY THE PRESIDENT OF THE UNITED STATES OF AMERICA A PROCLAMATION The Basin and Range area of southeastern Nevada is an iconic American landscape. The area is one of the most undisturbed corners of the broader Great Basin region, which extends from the Sierra Nevada Mountains in the west to the Colorado Plateau in the east. The pattern of basin, fault, and range that characterizes this region creates a dramatic topography that has inspired inhabitants for thousands of years. The vast, rugged landscape redefines our notions of distance and space and brings into sharp focus the will and resolve of the people who have lived here. The unbroken expanse is an invaluable treasure for our Nation and will continue to serve as an irreplaceable resource for archaeologists, historians, and ecologists for generations to come. Over both geologic and historical time, the Basin and Range area has been a landscape in motion. The area exemplifies the unique topography and geologic history of the Great Basin region and has long been the subject of studies of the tectonic and volcanic mechanisms responsible for this landscape, including crustal extension, deformation, and rifting. The thrust and fault block formations found here, along with the area's stratigraphy, have been instrumental in understanding the nearly 500 million-year history of the region. Among the geologic features found in the Basin and Range area are natural arches, caves, and sheer cliffs that offer stunning vistas. -

The proposed Basin and Range National Monument (BRNM) (Figure 1) is a study in contrasts between jagged mountain ranges and flat basin valleys, each of which hosts very different ecosystems and offers people diverse suites of hard‐won resources. During the early, relatively wet Paleoindian period lakes formed in the valleys and food was comparatively abundant. However, since the advent of arid modern climatic conditions during the subsequent Archaic period, prehistoric hunter‐gatherers, protohistoric tribes, and even modern ranchers have had to move between ecosystems to access as many different resources as possible in order to survive. Native American trails that wind through the area are both literal and figurative reminders of these interconnections between the basins and ranges. Only about two percent of the BRNM has been investigated for archaeological resources but the resulting picture is one of regular seasonal movements by hunter‐gatherers throughout prehistory and protohistory. -

The purpose of this study is to describe and interpret deposi- tional sequences within the Guilmette in this area. The Guilmette Formation was subdivided into three Members based on its lithology and depositional processes. The Lower Member is composed of interbedded limestone and dolomite deposited as shallowing-upward cycles in a shallow platform environment. -
