The Sunkist Citrus Plant in Ontario, California, processes about 6 million pounds of citrus fruit per day to make products which include frozen concentrated juice; chilled, pasteurized, natural strength juice; molasses from peel; dried meal from peel; pectin; citrus oil; and bioflavonoids. The energy intensive operations at the plant include concentration, drying, and refrigeration. The objective of the two-year two-phase project is to identify an economically viable alternative to the existing method of meeting energy requirements. Progress on the technical work of Phase I is reported. The following are summarized: requirements (energy price projection, atmospheric emission requirements, citrus juice quality constraints, economic evaluations); characterization (basic citrus processing operations, energy consumption and fruit processed vs time, identification and measurement of energy uses, energy balance for a typical citrus juice evaporator); and thermodynamic analysis (heat pump model, thermal evaporator, and co-generation model).

From introduction: "The Bakersfield sheet of the Geologic Map of California (California Division of Mines and Geology, 1978) was used as a basis for the interpretation of the geophysical data. The formation descriptions in Appendix C are derived from this map."

From introduction: The Fresno sheet of the Geologic Map of California (California) Division of Mines and Geology, 1978) was used as a basis for the interpretation of the geophysical data. The formation descriptions in Appendix C are derived from this map. Parts of three physiographic provinces are present in the Fresno quadrangle (Albers, 1966)...

From abstract: This data report presents results of ground water and stream sediment reconnaissance in the National Topographic Map Series (NTMS) Death Valley 1 x 2 quadrangle.

From abstract: This abbreviated data report presents results of ground water and surface sediment reconnaissance in the National Topographic Map Series (NTMS) Salton Sea 10 x 2 quadrangle. Surface sediment samples were collected at 997 sites. Ground water samples were collected at 76 sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 9 other elements in ground water. Mass spectrometry results are given for helium in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps.

Introduction: The geologic map of the Mariposa quadrangle, which was used as a basis for the interpretation, was supplied by Bendix Field Engineering Corporation. The Formation descriptions in Appendix C are derived from this map supplemented with information from California Division of Mines and Geology (1967).

From introduction: Our particular interest in the uranium potential of the Proterozoic quartz-pebble and quartzite-pebble conglomerates of the Kingston Peak Formation has been based upon: 1. Known uranium occurrences of low to intermediate grade in a peliticarkosic sulfide-bearing unit near the base of the formation; the "Favorable Submember" of this report. 2. Uranium occurrences and widespread anomalies in underlying Proterozoic granitic-metamorphic rocks, including the World Beater Complex, within and bordering the basin in which the conglomerates were deposited. 3. Reported minor shows of uranium associated with extensive anomalous radioactivity in the conglomerates themselves.

From project objectives: The Sonora Pass region was identified by the U. S. Department of Energy (DOE) as a potential uranium resource area because of past uranium production at the Juniper Mine and reported high-grade occurrences in other buried fluvial channels which are Tertiary in age. The objective of the Sonora Pass drilling project was to obtain subsurface data that would increase the accuracy of uranium reserve estimates for the project area.
