SECTION 2.0:PROJECT DESCRIPTION <br /> 2.1.15.6 Instrument Air <br /> The instrument air system will provide dry air to pneumatic operators and devices. An <br /> instrument air header will be routed to locations within the facility equipment areas and <br /> within the water treatment facility where pneumatic operators and devices will be located. <br /> 2.1.16 Interconnect to the Electrical Grid <br /> The CTG and the STG will be connected to a single,three-winding,three-phase step-up <br /> transformer that will be connected to the existing 230-kV switchyard adjacent to the STIG <br /> plant. The connection at the existing switchyard connection will consist of a single 230-kV, <br /> SF6 circuit breaker and associated air break disconnect switches connected in a radial feed <br /> scheme. Refer to Section 3.0 for additional information on the switchyard and transmission <br /> line. <br /> 2.2 Project Construction <br /> Construction of the generating facility,from demolition,site preparation,and grading to <br /> commercial operation,is expected to take place from the first quarter of 2010 to the first <br /> quarter of 2012,24 months total. Major milestones are listed in Table 2.2-1 <br /> TABLE 2.2-1 <br /> LEC Project Schedule Major Milestones <br /> Activity Date <br /> Begin Construction First Quarter 2010 <br /> Startup and Test Fourth Quarter 2011 <br /> Commercial Operation First Quarter 2012 <br /> There will be an average and peak workforce of approximately 168 and 305 respectively, of <br /> construction craft people,supervisory, support, and construction management personnel on <br /> site during construction (see Table 5.10-11 in Section 5.10,Socioeconomics). <br /> Typically,construction will be scheduled to occur between 6 a.m. and 11 p.m. on weekdays <br /> and Saturdays. Additional hours may be necessary to make up schedule deficiencies, or to <br /> complete critical construction activities (e.g.,pouring concrete at night during hot weather, <br /> working around time-critical shutdowns and constraints). During some construction <br /> periods and during the startup phase of the project, some activities will continue 24 hours <br /> per day, 7 days per week. <br /> The peak construction site workforce level is expected to last from month 11 through month <br /> 18 of the 24-month construction period,with the peak being month 16. Table 2.2-2 provides <br /> an estimate of the average and peak construction traffic during the 24-month construction <br /> period. <br /> 2-32 SAC/371322/082340003(LEC_2.0_PROJECT_DESC.DOC) <br />
