Environmental Analysis <br />UTILITIES AND SERVICE SYSTEMS <br />SCE serves much of southern California; its service area extends from Orange and Riverside counties in the <br />south to Santa Barbara County in the northwest and Mono County in the north. SCE estimates that total <br />electricity consumption in its service area will increase from 99,224 GWh in 2011 to 109,888 GWh in 2020 <br />(CEC 2012); one GWh is one million kWh. <br />Table 5.14 -6 Estimated Existinq Electricity Demands <br />Land Use <br />Amount (DU or BSF) <br />Electricity Demands, kWh ear <br />Per Unit (BSF or DU)' <br />Total Demand <br />Office Park <br />815,346 <br />17.97 <br />14,651,768 <br />General Light Industrial <br />505,037 <br />9.65 <br />4,873,607 <br />Apartments Mid Rise <br />739 <br />3589 <br />2,652,360 <br />Strip Mall <br />633,878 <br />13.44 <br />8,519,320 <br />Total <br />30,697,055 <br />1 Soumz: SCAQMD 2011 <br />5.14.1.6 NATURAL GAS <br />The Southern California Gas Company (SCGC) provides natural gas to most of southern California, from <br />Imperial County in the south to part of Fresno County in the north. Total natural gas supplies available to <br />SCGC are forecast to remain constant at 3.875 billion cubic feet per day from 2010 through 2030 (CGEU <br />2012). Estimated existing natural gas demands in the project site are about 32.9 million kBTU per year. One <br />kBTU is equivalent to about 1.03 cubic feet of natural gas. <br />5.14.2 Thresholds of Significance <br />According to Appendix G of the CEQA Guidelines, a project would normally have a significant effect on the <br />environment if the project: <br />U -1 Would exceed wastewater treatment requirements of the applicable Regional Water Quality <br />Control Board. <br />U -2 Would require or result in the construction of new water or wastewater treatment facilities or <br />expansion of existing facilities, the construction of which could cause significant environmental <br />effects. <br />U -3 Would require or result in the construction of new storm water drainage facilities or expansion <br />of existing facilities, the construction of which could cause significant environmental effects. <br />U -4 Would not have sufficient water supplies available to serve the project from existing entitlements <br />and resources, and new and /or expanded entitlements would be needed. <br />U -5 Would result in a determination by the wastewater treatment provider which serves or may serve <br />the project that is has inadequate capacity to serve the project's projected demand in addition to <br />the provider's existing commitments. <br />Page 5.14 -12 PlaceWorkr <br />
