Where "H" is the Height of Stack in meters; and "Q" is the maximum quantity of SO2 expected to go out through the stack at 110% of the rated capacity of the plant as per the norms of gaseous emission. Whenever this formula is revised, the same will be applicable for determining the stack height in respect of the plants commissioned after notification of revised formula for stack height.
