E.2 Air Resources E.2.1 Air Quality E.2.1.1 Regulatory Framework The following regulatory framework identifies the federal and state agencies in charge of monitoring and controlling mobile and stationary sources of air pollutants and describes measures APPENDIX E-4 WEST MOJAVE (WEMO) ROUTE NETWORK PROJECT SUPPLEMENTAL ENVIRONMENTAL IMPACT STATEMENT taken to achieve and maintain healthful air quality in the WEMO planning area. This section summarizes the applicable regulations related to the Proposed Project. Rules and regulations promulgated by the federal, state or local agencies impose limits on emissions from sources of air pollutants. These agencies manage mobile sources of air pollutants and exhaust from off-road vehicles (OHVs) through emission performance standards and fuel formulations requirements. Federal The Environmental Protection Agency (EPA) implements and enforces the requirements of most federal environmental laws. EPA Region 9 administers federal air programs in California. The federal Clean Air Act (CAA) provides the EPA with the legal authority to regulate air pollution from stationary and mobile sources. The EPA has authority over conformity issues with the CAA in areas that do not meet national ambient air quality standards (NAAQS). The EPA has delegated the authority to review to the California Air Resources Board (ARB). The ARB has further delegated this authority to Air Quality Management Districts (AQMDs) and Air Pollution Control Districts (APCDs) established throughout the state. Federal land management agencies also are responsible for conformity issues related to federal activities and projects that federal land managers authorize in conjunction with the AQMDs and APCDs. Federal Clean Air Act (CAA) The CAA, enacted in 1970 and amended in 1977 and 1990 (42 United States Code [U.S.C.] 7401 et seq.), protects and enhances the quality of the nation’s air resources to benefit public health, welfare, and productivity. The CAA regulates certain forms of air pollution under three main categories: criteria pollutants, air toxics, and global warming and ozone-depleting gases. Regulation also covers a more general category of emissions that reduce visibility: regional haze, prevention of significant deterioration (PSD),

SCHNEIDER The problems of geoarchaeology addressed in this paper were probably most clearly stated very early in the research, almost 40 years ago (Warren and DeCosta 1964). To adequately date the artifact assemblages from the 24 "surface sites" on the high beach lines of Pluvial Lake Mojave, two tasks must be successfully completed: (1) construct the geomorphic history of Lake Mojave from the strafigraphy, topographic re/afionships, radiocarbon dates, and any other useful data, and (2) demonstrate the stratigraphic relationship between prehistoric artifacts and lacustrine deposits of Lake Mojave. These two tasks are addressed in this paper, demonstrating the sequence of beach-ridge INTRODUCTION formation at Lake Mojave (Antevs 1937; Ore and Warren 1971; Wells et al. 1989).

  • Harper Valley Groundwater Basin Bulletin 118
    South Lahontan Hydrologic Region California’s Groundwater Harper Valley Groundwater Basin Bulletin 118 Harper Valley Groundwater Basin • Groundwater Basin Number: 6-47 • County: Kern, San Bernardino • Surface Area: 410,000 acres (640 square miles) Basin Boundaries and Hydrology This groundwater basin underlies Harper Valley in western San Bernardino and eastern Kern Counties of the central Mojave Desert. This basin is bounded on the east by nonwater-bearing rocks of Fremont Peak, Black Mountain, the Gravel Hills, and the Mud Hills. The basin is bounded on the west by a combination of surface drainage divides, portions of the Harper, Kramer Hills and Lockhart faults, and nonwater-bearing rocks of the Kramer Hills and other low-lying basement hills. The basin is bounded on the south by nonwater-bearing rocks of Mount General, Iron Mountain, and the Waterman Hills, and by subsurface drainage patterns. The basin is bounded on the north by nonwater-bearing rocks of the Rand Mountains (DWR 1964; Jennings and others 1962; Rogers 1967) Harper Valley is drained by numerous ephemeral streams towards Harper (dry) Lake (Jennings and others 1962; Rogers 1967). Floodwater from Grass Valley occasionally flows into Harper Valley via Black Canyon on the eastern side of the valley (DWR 1964). Average annual precipitation is about 5 inches and ranges from about 3 to 7 inches. Hydrogeologic Information Water Bearing Formations Quaternary lacustrine and alluvial deposits, including unconsolidated younger alluvial fan material and unconsolidated to semi-consolidated older alluvium, can be water-bearing within the basin. The younger alluvium generally lies above the groundwater surface; whereas, the older alluvium extends beneath the groundwater table (DWR 1971).

  • Jay Von Werlhof Imperial Valley College Desert Museum El Centro, California
    DISTRIBUTION AS A FUNCTIONAL FACTOR OF ROCK ALIGNMENTS IN THE MOJAVE DESERT Jay Von Werlhof Imperial Valley College Desert Museum El Centro, California ABSTRACT This paper suggests that the distribution, setting, content, and form of early rock alignments in the Mojave Desert are directly related to the function of these features. Each of these factors will be described and discussed in turn, leading to an interpretive synthesis. Why a reliable model cannot be developed for locating rock alignment sites is also suggested.

Enzel et al. maintain that this et al.’s comment, let me put the size of the lake under discussion shoreline is cut into colluvium and, at its southeastern end, into in perspective. If water were to fill Death Valley to the 90-m alluvial fan deposits. I agree with the former. On the other hand, level today, the surface area would be 1600 km2 (Meek, 1997), air photos, a map in Anderson and Wells (1997), and my own whereas the area Hale proposed, based on overflow at Ash Hill observations do not support the interpretation that it is cut into an pass, would have been 8000 km2 (Hale, 1985).

  • Draft DRECP and EIR/EIS – Appendix L, Bureau of Land Management Worksheets
    Harper Dry Lake Description/Location: Harper Dry Lake is a year‐round marsh and wetland utilized by a variety of resident and migratory bird species, as well as a watchable wildlife area for viewing these species. It is located within and along the southwestern border of Harper Lake playa in San Bernardino County, approximately twenty miles northwest of Barstow off of Harper Lake Road. Nationally Significant Values: Ecological: Harper Dry Lake is recognized as a Key Raptor Area by the BLM, which designated 223 areas nationwide. Key Raptor Areas are places known to be significant habitats for selected species of birds of prey, and Harper Dry Lake is 1 of 7 Key Raptor Areas in the California desert. The species known to utilize the habitat at Harper Dry Lake are northern harrier, short‐eared owl, ferruginous hawk, and long‐eared owl. Special Designations/Management Plan/Date: This ACEC was designated in the CDCA Plan of 1980, and the management plan was approved in June of 1982, and later in 2006, additional management provisions were incorporated in the plan. Relevance and Importance Criteria: Relevant biological resources. Before early settlement and adjacent agricultural activities, this playa possessed a shallow water table feeding a productive meadowland habitat. At that time, surface water flowed in the Mojave River throughout the year in much of the West Mojave and spring flows were frequent. With the advent of ranching and later agriculture, much of the Harper Lake meadowland was degraded, and with additional populations and dams, Mojave River flow has been substantially reduced and flows down river of the Victor Valley area are infrequent.

  • Appendix D Mojave River Exhibit
    APPENDIX D MOJAVE RIVER EXHIBIT Floor Unit The floor unit will be a free-standing, three dimensional representation of the Mojave River and adjacent lands. Pleistocene lakes and present day features will be labeled. See Figure 1. Four horizontal panels will be attached to the floor unit. Two large vertical panels will be adjacent to the floor unit. One will be the modified existing panel on Afton Canyon and Pleistocene Lake Manix. Figure 1. Map For Floor Unit (after Automobile Club of Southern California, 2002; Reheis, et al, 2015). D-1 Panels Adjacent to Floor Unit The four panels mounted on the sides of the floor unit will contain addition information about subjects related to the Mojave Desert, both during the Pleistocene and Holocene. The four panels going clockwise from the top of the exhibit will discuss thermoregulation by the shasta ground sloth (Nothrotheriops shastensis), eolian activity, the flood plain aquifer, and gold processing. Each panel will contain text and diagrams. Free Standing Panels The existing panel with information on Afton Canyon and Lake Manix is shown in figure 2. The heading will be changed to "The Mojave: the River that Grew in Your Own Backyard". Otherwise, it will be unchanged. The text of the existing panel is difficult to read in Figure 2; its text is given below: Afton Canyon: During the later part of the Pleistocene Epoch, Lake Manix extended eastwards as far as Cave Mountain and the Cady Mountains, just west of Soda Lake. After approximately 21,000 years ago, as the last glacial pulse of the Ice Ages was waning, Lake Manix overtopped its eastern threshold and catastrophically drained to the east, forming a new lake - Pleistocene Lake Mojave.
