The CEQA Guidelines include provisions for assessing the cumulative impacts of projects with GHG 21emissions. According to the guidelines, the lead agency “may determine that a project’s incremental 22contribution to a cumulative effect is not cumulatively considerable if the project will comply with the 23requirements in a previously approved plan or mitigation program (including, but not limited to, … plans 24or regulations for the reduction of GHG emissions) which provides specific requirements that will avoid 25or substantially lessen the cumulative problem” (Section 15064[h][3]). According to this section, if an 26adopted plan or program adequately addresses cumulative GHG emissions and would apply to proposed 27development, the determination may be made that the development would not result in a cumulatively 28considerable impact, as long as the plan or mitigation program being relied upon imposes requirements 29that adequately address cumulative GHG emissions. In addition, in order to appropriately determine and 30mitigate GHG impacts, the plan or mitigation program must provide specific requirements that will avoid 31or substantially lessen the cumulative impact, must be specified in law or adopted through a public review 32process, and must be enforceable. 33 34TheproposedprojectwouldgeneratedirectemissionsofGHGsfromequipment/vehicleusage35duringconstructionandoperationandfrompotentialsulfurhexafluoride(SF6)leakagefrom36electricalequipment.TheSantaBarbaraCountyAirPollutionControlDistricthasnotestablished37significancecriteriaforGHGemissions(SBCAPCD2011).TheVenturaCountyAirPollutionControl38District(VCAPCD)isconsideringatieredapproachtoassessingGHGemissionswiththemain39componentsinvolvingconsistencywithalocallyadoptedGHGreductionplan,followedbyabright‐40linethresholdforsomeprojects(VCAPCD2011).GiventhattheVCAPCDhasnotyetformally41adoptedGHGemissionsthresholds,theyarecurrentlydeferringtotheinterimsignificance42thresholdsestablishedbytheSouthCoastAirQualityManagementDistrict(theadjacentairquality43jurisdiction).ThenetGHGemissionchangeassociatedwithconstructionoftheproposedproject44wouldbelessthantheSCAQMDinterimGHGsignificancethresholdof10,000metrictonsofcarbon45dioxideequivalency(CO2e)peryear.Itisestimatedthattheproposedprojectwouldresultinan46increaseof8,458metrictonsofCO2eduringconstructionandthatoperationalemissionswould47remainunchanged,asdiscussedinSection4.7,“GreenhouseGasEmissions.”48 49
