SECTION 2.0:PROJECT DESCRIPTION <br /> building is complete. The relocation project will be permitted by the City of Lodi and <br /> construction is expected to occur in 2009 to facilitate the move in 2009. Although the LEC <br /> will ultimately share the use of the remodeled administration building and new warehouse, <br /> this activity will take place with or without the LEC and,therefore,is not part of the LEC <br /> project. <br /> 2.1.3.2 WPCF Ongoing Activities <br /> The LEC site is currently being used by the City of Lodi as a construction staging and <br /> equipment storage area for ongoing WPCF expansion and maintenance projects. These <br /> activities are not part of the LEC project; they are being performed by the City of Lodi and <br /> are not dependent on the LEC moving forward. <br /> 2.1.3.3 STIG Plant Ammonia Tank Upgrade Project <br /> As part of its Risk Management Plan(RMP) review, the STIG plant is currently updating the <br /> existing anhydrous ammonia storage system. The project will not increase storage capacity, <br /> but the storage system will be configured with active and passive measures designed to <br /> meet a performance standard of reducing the offsite consequence analysis to less than <br /> 75 parts per million(ppm) at the closest public receptor. This project will be completed <br /> before the LEC becomes operational and will be undertaken whether or not the LEC moves <br /> forward. <br /> 2.1.4 Process Description <br /> The LEC power train will consist of the following components: (1) one"Rapid Response' <br /> General Electric (GE) Energy Frame 7FA combustion turbine-generator (CTG), equipped <br /> with dry low NO,,combustors for the control of NO, and an evaporative cooler for <br /> reducing inlet air temperatures; (2) one heat recovery steam generator (HRSG) with duct <br /> burners; (3) selective catalytic reduction (SCR) and oxidation catalyst equipment to control <br /> NO,,and carbon monoxide(CO) emissions,respectively; (4) a condensing STG; (5) a <br /> deaerating surface condenser; (6) a 7-cell mechanical draft cooling tower; (7) a small <br /> auxiliary boiler (45,000 lb/hr); and (8) associated support equipment. <br /> The CTG will use"Rapid Response" technology offered by GE,the supplier of the project's <br /> combustion equipment. This technology allows for faster starting of the gas turbines by <br /> mitigating the restrictions of older HRSG designs. Traditionally, CTGs are started up slowly, <br /> with long hold times at low load points,to limit combined stresses in the high-pressure <br /> steam drum of the HRSG and to maintain steam conditions for the steam turbine. The Rapid <br /> Response technology eliminates this restriction by modifying the steam drum design. The <br /> Rapid Response package includes an auxiliary boiler that preheats the CTG fuel and <br /> provides STG sealing steam prior to CTG startup;thereby, allowing the condenser vacuum <br /> to be established and the condenser be in a condition ready to accept steam earlier in the <br /> startup cycle. This allows earlier startup of the steam turbine and helps to shorten hold <br /> times for the CTG. <br /> The CTG will generate approximately 170.9 MW at annual average ambient conditions. The <br /> CTG exhaust gases will be used to generate steam in the HRSG. The HRSG will employ a <br /> triple-steam-pressure design with duct-firing equipment. Steam from the HRSG will be <br /> admitted to a condensing STG. The STG will produce approximately 96.4 MW under <br /> SACI371322I082340003(LEC_2.0_PROJECT_DESC.DOC) 2-9 <br />
