The aggregate capacity of all petroleum tanks is approximately 16,000,000 barrels. In addition there are numerous other tanks, generally smaller in size, used for storage of various treatment chemicals, wastewater, firewater, and other water streams. In general, Refinery tanks are designed and maintained to Chevron and industry consensus standards such as those from the American Petroleum Institute, Codes of Management Practices of the Chemical Manufacturers; American National Standards Institute B31.1: Power Piping; American National Standards Institute B13.3: Petroleum Refinery Piping; National Fire Prevention Association 30; and the Uniform Building Codes. Such design standards are routinely evaluated and revised as necessary to improve safety and reliability. Whenever new facilities are built, they must meet these improved design codes and industry standards. Environmental regulations, primarily from the United States Environmental Protection Agency (US EPA) or the Bay Area Air Quality Management District (BAAQMD) require new tanks to meet lower emission levels of organic vapors especially for materials that have higher vapor pressures (such as gasoline). Additionally, oil spill prevention regulations under the federal regulations (Title 40 of the Code of Federal Regulations, Section 112), and the California Aboveground Petroleum Storage Act (Health and Safety Code, Division 20, Chapter 6.67) require secondary containment and other spill prevention measures for petroleum storage tanks. To ensure the proper storage and handling of petroleum products, Refinery tanks are inspected in accordance with industry codes, including the American Petroleum Institute Standard 653 (API-653), “Tank Inspection, Repair, Alteration, and Reconstruction.” To accomplish certain inspections required by this standard, tanks must be taken out of service on a periodic basis, cleaned, and inspected internally. Routine repairs will be made during this time and additional repairs may be made depending on the results of the inspections. Such cleaning, inspection, and repairs may take 6 to 12 months to complete. At some point, a tank will reach its end-of-life, and will then be permanently removed from service. Under normal circumstances, the Refinery has about one tank under construction at all times in order to comply with legally-required tank inspection and maintenance schedules, end-of-life tank replacements, and changes in tank service. However, Chevron has not built any new tanks at the Refinery in over five years. New tanks are needed to allow certain tanks to be removed from service for legally-required inspections and to replace several tanks that have already been removed from service. Accordingly, Chevron plans to replace five existing petroleum storage tanks with five newly constructed tanks. The summary of the tank changes is provided below in Table 1-1. In addition, to improve fire response capabilities to meet California Fire Code requirements, Chevron plans to construct a new firewater tank in the Quarry Tank Field. The firewater tank will be situated on an elevated site above the Quarry Tank Field to gravity feed firewater to the Quarry Tank Field in order to improve firefighting

    4.3 GEOLOGY AND SOILS This section describes the geology, soils, and seismicity of the Specific Plan area. The information presented below has been developed based on several sources of data. These sources include Geotechnical Investigation for the Niven Nursery Site (Harza Engineering Company 1998a) (Appendix C-1); Review of Geologic Conditions for the Central Larkspur Area Specific Plan, Larkspur, California (World Environmental Science & Technology 1999) (Appendix C-2); personal communication with Miller Pacific Engineering Group (Appendix C-3); and review of published literature, maps, and Internet sites on geology, soils, and seismicity of the area. 4.3.1 EXISTING SETTING REGIONAL SETTING The Specific Plan area lies in the central portion of the Coast Ranges Geomorphic Province in the seismically active San Francisco Bay Area. The northwest to southeast trending ridges and valleys of the Coast Ranges have formed in response to the active tectonism of the region. Tectonics of the region are controlled by the San Andreas Fault System. The northwest to southeast striking San Andreas fault represents the boundary between the Pacific Plate, primarily offshore to the east-southeast, and the North American Plate, primarily onshore to the west- northwest. In response to the relative northwest movement of the Pacific Plate with respect to the North American Plate, other faults have formed. These include fault structures such as the Hayward fault, the Rogers Creek fault, and the Calaveras fault, all located within 25 miles of the site. Large-magnitude earthquakes could be generated on any of these regional active faults. The regional geology of the area is characterized as part of the Franciscan Complex of Jurassic to Cretaceous age.

We have applied the solutions of Yoffe (1960) and Comninou (1973) for an angular dislocation line to the problem of calculating the fields due to general polygonal dislocations. Next, anumerical method has been developed explicitly for finite sources (Finite Source Method or FSM) which allows the computation of fields from a dislocation that penetrates several layers of a layered half-space. The speed of the FSM allows the calculation of many models which are not econom- ically possible by other means. It is used here to model 3 earthquakes in layered media and plate bottom effects due to the interaction of lithospheric plates. Finally,

  • CHAPTER 5 GEOLOGY, SOILS, and SEISMICITY the Geologic, Soil and Seismic Impact Evaluation of the Proposed Bulk Materials Process
    CHAPTER 5 GEOLOGY, SOILS, AND SEISMICITY The geologic, soil and seismic impact evaluation of the proposed Bulk Materials Processing Center (BMPC) use permit amendment changes and related actions (Project) are addressed in this chapter. The geologic environment of the West Contra Costa County Sanitary Landfill (WCCSL) plays a major role in the design and construction of the improvements and in the analysis of issues in this chapter. A. SETTING 1. Regional The regional setting of the WCCSL area is discussed in this section. Discussion is included on the physiography, geology, faults, earthquakes, and soils. a. Physiography. The San Francisco Bay estuary extends from the Golden Gate Bridge to the Sacramento - San Joaquin Delta and includes San Pablo, Richardson, and Suisun Bays. The shorelines of the estuary margins are characterized by low elevation marsh and tide lands that are dominated by marsh flats and meandering creek channels with few isolated areas of higher elevations. Prior to 1850, marshes covered an area of about 860 square miles. Since the Gold Rush era, most pre-existing marshes have been levied or filled; these activities have promoted the erosion of some of the existing marshes and have assisted in the creation of other new marshes by both accident and design. All but approximately an area of 33 square miles of these marshes have been levied or filled during the past 125 years. Concurrently, human activities have caused the delivery of enormous quantities of sediment to the bays, thereby contributing to the creation of nearly 29 square miles of marsh.70 b. Geology. The San Francisco Bay Area lies within the Coast Ranges geologic and physiographic province.

F. RICHTER ABSTRACT In the USSR earthquake risk is now officially mapped by division into areas numbered with the degrees of the Modified Mercalli intensity scale, to show maximum reasonably expectable intensity during future earthquakes on ground of the prevailing character. This paper presents and discusses maps on the same plan for the Los Angeles Basin and its vicinity, for California, and for the United States. The effect of variation of ground from point to point can be shown only on a large scale. This is microregionalization; the map for the Los Angeles Basin is an example. Small-scale regionaliza- tion maps require generalization. Prevailing ground is selected, not strictly by percentage of area, but by considering the foundation likely to be used for construction, in mountainous areas mostly small alluvial patches less stable than the surrounding rock. Regionalization and especially mieroregionalization can be used in construction and planning, as indicating maximum effects to be considered in designing permanent structures. In adjusting insurance rates, and in designing temporary structures, statistical frequency of occurrence is also involved. Over small areas, regionalization depends largely on local variation of ground and geology; over large areas, distance from active faults must be considered. Attention Should be given to the effect of structural trends and of wave path on the form of isoseismal curves. Mapping for the Los Angeles Basin area is reasonably definite.
