• (3) The owner or operator shall determine the loading for each calendar quarter using the following formula:

  QL = C × V / 1,000

  where

  QL 

  is the loading for a calendar quarter;

  C 

  is the mean of the monthly mean concentrations of the deleterious substance for that calendar quarter, recorded under section 19.1; and

  V 

  is the total volume of effluent deposited from each final discharge point during that calendar quarter, based on the sum of the total monthly volumes of effluent deposited from each final discharge point, recorded under section 19.
