5. Environmental Analysis NENEEEEEE� AIR QUALITY 1. 5 Cumula ive Impacts In accordance with the SCAMD methodology, any project that produces a significant regional air uality impact in a nonattainment air basin will have a cumulative impact. Cumulative projects within the local area include new development and population growth. The greatest source of emissions within the SoCAB is mobile sources. The S CAQM D considers a project cumulatively significant when project - related emissions exceed the SCAOMD regional emissions thresholds shown in Table 5.1-6, Construction The SoCAB is in nonattai nment for o., PM, 0, and PM2.5F SCAOM D's air quality thresholds were developed to identify projects that would substantially contribute to the SoCAB's nonattainrnent status. Project - related construction activities would not exceed the SCAOM D's air quality thresholds. Therefore, the project would not significantly contribute to the regional non attainment designations of the SoCAB and impacts mould not be cumulatively considerable. Operation For operational phase air quality emissions, any project that does not exceed or can be mitigated to less than the SCAQUID's daily regional threshold values is not considered by the SCAOMID to be a substantial source of air pollution and does not add significantly to a cumulative impact. The project would not generate long -term emissions because it would not generate new trips or change eciting traffic patterns on the local roadways. As described in Impact 5.1 -3 , the project would not substantially elevate CO concentrations at local intersection;. In consideration of the preceding factors, the project's contribution to cumulative long- term air quality impacts would not be cumulatively considerable and impacts would be less than significant, Global Farming Project - related GHG emissions are not confined to a particular air basin but are dispersed worldwide. Consequently, it is speculative to determine how project - related GHG emissions would contribute to global climate change and how an individual project's GHG ernissions would impact California. Therefore, impacts identified under impact 5.1 -4 are not project- specific impacts to global warming but the project's contribution to this cu m ulative impact. G H G emissions from construction of the project world not be substantial and its contribution to global climate change impacts would not be cumulatively considerable, 5.1.6 Existing Regulations and Standard Conditions • SAQIID Rule 201: Permit to Construct a BCAMD Rule 402: Nuisance Odors * BCAMD Rule 403: Fugitive Dust * ARB Rule 2480: Airborne Tonics Control Measure • Motor Vehicle Standards AB 1493) 5. 1.7 Level of Significance Before Mitigation Upon irnplernentation of regulatory requlrernents and standard conditions of approval, the following impacts would be less than significant: .1 -1, 5.1-2, 5.1-3, and 5.1 -4, FairhavenlLincoln and Santa ' a a inco n Interjection 11 odific ion r City of an Ana a Page .1 -1 Supplement to the Santa Ana Second Main Track Project EIR Resolution No. 2009 -034 Page 65 of 130
