SECTION 1.0:EXECUTIVE SUMMARY visual or scenic quality from key observation points range from low to moderately low. Although the,viewer sensitivity at the key residential observation point is rated as high,the project is not located in a scenic or protected viewshed. Although the project will be seen by viewers leaving or entering suburban residential areas in Stockton to the south, these areas are 2 miles away,and the LEC will not significantly degrade the scenic quality of the existing viewshed,and will be located in an existing industrial area. Section 5.13 contains a detailed discussion of the visual resources assessment. 1.5.5 Water Resources The water to be used for power plant cooling and process water will be tertiary-treated reclaimed water supplied by the WPCF. The facility will have limited industrial process water discharge. Total water use would be about 856 gallons per minute,or about 450 million gallons per year (1,380 acre-feet), assuming, as a maximum case,full-time operation (8,760 hours per year). In actuality, the project will be out of operation for maintenance and for other reasons and will not operate all hours. At 4,500 operating hours per year,total water usage would be about 231 million gallons (709 acre-feet per year). The majority of the plant process wastewater will be disposed of in a Class I UIW. The remaining small portion (e.g., CTG compressor water wash)will be captured in underground tanks and disposed of appropriately.) Stormwater runoff from the project site during construction and operation will be carefully controlled in accordance with an engineered drainage system, an oil-water separator,and standard best management practices.The project would not have an adverse effect on the availability or quality of water resources. Section 5.15 contains a detailed analysis of water resources. 1.6 Key Benefits 1.6.1 Environmental The LEC will use advanced,high-efficiency,combined-cycle combustion turbine technology and SCR to minimize emissions from the facility. NO,,emissions (a precursor to ozone formation) produced by the LEC will be at least 90 percent less per megawatt than the emissions produced by many older,existing power plants. In addition to the significant reduction of emissions,the LEC operating efficiency will be such that the plant will consume less fuel than older plants of similar size. The use of tertiary-treated water as primary cooling and process water for the LEC will prevent an additional continuous demand on the local potable water system and will allow effective use of the area's recycled water supply. 1.6.2 Employment and Economic Benefits The project will provide for a peak of approximately a maximum of 305 construction jobs over a 24-month period. The average number of workers during the construction period will be 168. The facility will permanently employ 21 to 23 persons (16 existing staff from the NCPA Combustion Turbine Projects,and 5 to 7 new employees),including power plant 1-12 SAC/371322/082330001(LEC_1.0_EXECUTIVE_SUMMARY.DOC)
