Values above which represent less than 0.005 are automatically rounded <br />down and shown as <0.01. <br /> <br />As shown in Table 4, the construction emissions from all construction activities are below the <br />recommended thresholds of significance; therefore, project construction would have less than <br />significant impact related to emissions of ROG, NOX, exhaust PM10, and exhaust PM2.5. As previously <br />discussed, the proposed project would implement Prior EIR MM 4.B-1a for dust control to reduce <br />potential impacts related to fugitive dust emissions during project construction.
