Air Quality and Greenhouse Gas Technical Report Griffith Energy Storage Project <br /> Each construction phase has the potential to generate the following: (1)fugitive dust emissions resulting <br /> from soil disturbance activity; (2)emissions of air pollutants from fuel combustion in construction <br /> equipment; and (3) emissions of air pollutants from fuel combustion in vehicles used for worker commute, <br /> equipment deliveries, and material hauling. Table 5 shows the construction schedule and Table 6 shows <br /> the construction equipment and vehicle trips. <br /> Table 5.
