Table 1 EMISSION THRESHOLDS OF SIGNIFICANCE Project Pollutant Construction Tons/ Operations Pounds/Day Quarter Pounds/Day Carbon Monoxide 550 24.75 550 Reactive Organic Compounds 75 2.5 55 Nitrogen Oxides 100 2.5 55 Particulate Matter 150 6.75 150 Long-term Operational Air Quality Impacts The primary source of long-term operational emissions associated with the proposed project would be generated by vehicle travel to and from the project site. A relatively minor amount of gaseous emissions would also occur from natural gas and electricity usage. The proposed project is consistent with the General Plan. The long-term operational emissions generated by the proposed proj ect are consistent with the air pollutant emission projections within the General Plan Land Use Element EIR. Implementation of the proposed project would not result in additional air pollutant emissions that would exceed air pollutant emission projections evaluated within the General Plan Land Use Element EIR. Short-term constructed Related Air Quality Impacts Construction operations associated with the proposed project could potentially result in short-term increases in particulate mater, and to a lesser degree increases in carbon monoxide and ozone. Peak day construction emissions for most pollutants arising from construction of the proposed project would occur during the grading and excavation phases. The majority of the construction operations for the proposed project would be interior tenant improvements. A minimal amount of exterior work would occur. Less than significant short-term air quality impacts would be associated with implementation of the proposed project. C. Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is 5 3IfÄ~:¿4
