Impact Assessment Potential air quality impacts expected from Melbourne Metro would be associated with construction activities. Some routine operational emissions would also be expected. Potential air quality impacts from the construction and operation of Melbourne Metro would be expected at precinct or local levels only. No significant adverse impacts to regional air quality would be anticipated. The main impacts identified in the air quality assessment are described below. Sections to describe these impacts as they apply specifically to each of Melbourne Metro precincts.
