2 Envr7�nmental Analysi.r <br /> • Use low sulfur fuel for stationary construction eyuipment,to the extent feasible. <br /> + LTse e�sting power sources (e.g.,power poles) ar clean fiael generators rather than <br /> temporazy power generators, to the extent feasible. <br /> • IJse low emission on-site stationary equipment,to the exte�t feasible. <br /> Operation oE the project would require testing the emeYgency generator up to 50 hours per year. <br /> Instaiiation of the diesel generator would rec�uire a permit from the BAAQMD, and the greenhouse <br /> gas significance level for the project would be 10,000 metric tons carbon dioxide equivalent per yeax. <br /> Eirussions fram testing the generator up to 50 hours a year would be less than 10 metric tons carbon <br /> dioxlde equivalent per pear,well below the signi�icance thxeshold. <br /> Praject operarions would also consume 75 mega�vatt hours (MWh.r) of electricity per year to operate <br /> the pump station and �.2 MWhr to operate lighting for the unde�crossing. Annual operationai <br /> emissions would result in 35.3 metric tons of carbon dio�de equivalent gases (see Appendix C}. <br /> Installal�on of the US 1d1 pedestrian and bicycle path undercrossing would reduce emissions of <br /> greenhouse gases,based on the 2.4 percent reduction in of mobile source emissions from the <br /> Bayfront,using Ca1EEMod modeling for the One Marina development,with and without the <br /> proposed project. This reduction woul.d lower greenhouse eriv.ssions bp at least 53.5 metric tons <br /> carbon dioxide equivalent pex peax, based on improved pedestrian access and reduced distance to <br /> Downtown and transit stations. The savings in emissions fxom the reduct�on in vehicle trips would <br /> be greater than the emissions from maintenance and power purchases, and the net result of the <br /> project would be a reduclion of at least 18.1 metric tons carbon dioxide equivalent emitted per year. <br /> This lower-bound estimate does not consider future development in the area,trips to nearby <br /> Convenrion Way and Main Stxeet,and assigns the 18 percent reducrion attributable to the One <br /> Marina location to the e�sting condirion,even through residents are nat]ikelp to walk or bike to <br /> Downtown without the proposed path. <br /> With the implementation of these measures and Mitigation Measute AIR 1, Basic Construcrion <br /> Mitigation Measures,the temporary impacts of the proJect to greenhouse gas concentrations and <br /> climate change wauld be less than significant. After a few years of operaiion, the anticipated <br /> reducrions in greenhouse gas emissions from the operation af the proposed project would offset the <br /> emissions from construction and xesult in a net benefit to atmospheric greenhause gas <br /> concentrations. {Less than Significant Impact with Mitigateon Iricorporation} <br /> 6) Conflrct with an applicable plan,policy or regulation adapted for the putpose ofreducrng <br /> the emissrons ofgreerihouse gases? <br /> The proposed project wauld be consistent with the applicable state and local plans, policies,and <br /> regulations regarding the reduction of greenhouse gases. The temporary increase in emissions would <br /> not interfete with the attainment of the AB 32 goals for 2020 and would contribute to the reductions <br /> required by the plan.
