19. Emission standards: Particulate matter emitted into the atmosphere by a hot mix asphalt plant must in no case exceed the quantities determined in Schedule C, depending on the applicable rate of production. When the rate of production is between 2 consecutive levels in Schedule C, the emission standard is determined by linear interpolation. Any existing hot mix asphalt plant that is enlarged or that increases its rate of production must comply with the emission standards applicable to new hot mix asphalt plants in accordance with Schedule C.
In addition, the concentration of contaminants issued into the atmosphere by a hot mix asphalt plant must be such that it does not exceed 20% opacity in accordance with one of the methods of measurement prescribed in the second paragraph of section 20.
