SECTION 2.0:PROJECT DESCRIPTION 2.5.2.10 Circulating Water System The circulating water system provides cooling water to condense steam turbine exhaust and steam turbine bypass steam. In addition,the system supplies cooling water to the various equipment coolers, such as lube oil coolers,throughout the plant via the auxiliary cooling water system. Major components of this subsystem are three 50-percent capacity,vertical, motor-driven circulating water pumps and associated pipes and valves 2.5.2.11 Compressed Air System The compressed air system will be designed to supply service and instrument air for the facility. Dry, oil-free instrument air will be provided for pneumatic operators and devices throughout the plant. Compressed service air will be provided to appropriate areas of the plant as utility stations consisting of a ball valve and quick-disconnect fittings. The instrument air system will be given demand priority over the service air system. A pressure control valve will be set at approximately 60 pounds per square inch (psi) to cut off the air supply to the service air header once the system pressure falls below 60 psi. Two 100-percent-capacity,water-cooled,oil free,rotary screw package air compressors will supply compressed air to the service and instrument air systems. 2.5.3 Fuel Availability Fuel will be delivered via a new 2.5-mile-long natural gas pipeline that will connect into PG&E's Line#108 east of the project site (see Section 4.0). PG&E has confirmed that its system has enough capacity to supply the LEC from this location. A will serve letter from PG&E is included as Appendix 2E. 2.5.4 Water Availability The LEC will use, on an annual average basis, 709 afy of recycled water provided by the WPCF for power plant cooling and process water,based on 4,500 operating hours per year. Potable water will be used for drinking, eye washes,safety showers,and service water from a new onsite well. The availability of water to meet the needs of LEC is discussed in more detail in Section 5.15, Water Resources. A will-serve letter from the City of Lodi is included in Appendix 2D. 2.5.5 Project Quality Control The LEC's quality control program is summarized in this subsection. The objective of the quality control program is to ensure that all systems and components have the appropriate quality measures applied;whether during design,procurement,fabrication,construction, or operation. The goal of the Quality Control Program is to achieve the desired levels of safety, reliability, availability, operability,constructability, and maintainability for the generation of electricity. The required quality assurance for a system is obtained by applying controls to various activities,according to the activity being performed. For example,the appropriate controls for design work are checking and review, and the appropriate controls for manufacturing 2-40 SAC/371322/082340003(LEC_2.0_PROJECT_DESC.DOC)
