III. Environmental Setting,Impacts, and Mitigations <br /> I. ENER Y <br /> SETTING <br /> Sources of Energy <br /> Oil,natural gas, nuclear and hydroelectric resources supply most of the power consumed in <br /> California. Oil provides about 54 percent of the state's energy need,while natural gas provides <br /> about 31 percent(California Energy Commission, 1990). The remaining 15 percent of the state's <br /> energy need is provided by nuclear and hydroelectric power,and by other sources,such as solar <br /> power and wind farms. The two major end-uses of energy are fuel for transportation and <br /> electricity. <br /> Energy Regulations.Plans and Policies <br /> The Cit of Stockton has goals and policies directed towards energy efficient building designs <br /> Y g P gY <br /> and transportation systems,but does not have any specific energy policy that would apply to the <br /> project(City of Stockton, 1990). <br /> AB 939 requires all California cities to reduce their waste stream tonnage by 25 percent in 1995 <br /> and 50 percent in 2000. The hierarchical methods for waste reduction are source reduction, <br /> recycling and composting, and landfilling and incinerating. Reducing total wastes generated <br /> .would reduce the energy required to transport and dispose of the waste. Recycling operations <br /> would conserve energy that otherwise would be used to manufacture products from raw <br /> materials. AB 939,therefore,would reduce the energy consumption of waste disposal-related <br /> transportation and manufacturing operations. <br /> Existing Energy on umntion <br /> Pacific Gas and Electric Company(PG&E)supplies electricity and natural gas to the City of <br /> Stockton,and to the project vicinity. Electricity,used at the landfill mainly for lighting <br /> purposes,is supplied by the on-site power plant. The current annual electricity consumption at <br /> the landfill is approximately 4,300 kilowatts(kV )(Fukumoto, 1993). <br /> The power plant,operated by Pacific Energy Company(PEn),currently generates a gross 800 <br /> kilowatt-hour(kWH)of electricity,of which 760 kWH is sold to PG&E(Donlou, 1993). About <br /> five to ten percent of the electricity generated is used on-site. This is equivalent to an annual <br /> - III.I.1 <br />
