Table A-1 EMISSION THRESHOLDS OF SIGNIFICANCE 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 project would be consistent with the air pollutant emissions projected within the General Plan Land Use Element FEIR. Short-term constructed Related Air Quality Impacts Construction operations for the proposed project would involve the grading of approximately 5,000 cubic yards of soil and a limited amount of building construction. Given the minimal amount of grading and construction activity, less than significant construction related air quality impacts are expected. However, dust generated from construction operations could be a nuisance to nearby land uses. To minimize dust impacts during construction, the proposed project would be subject SCAQMD Fugitive Dust Rule 403. To insure compliance with Fugitive Dust Rule 403 the following mitigation measure shall be implemented. Mitigation Measure • Grading plans and construction plans for the proposed project shall reflect the following notes: 8 3 �2 3 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.
