FORMULA USED TO CALCULATE POLLUTION/PERMIT FEE

Calculation of basic pollution fees or permit fees for the different categories of pollution source/

industry is done by considering the pollution potential of the effluent, the most effective

available effluent treatment technology and economic viability. The pollution sources are

categorised and key parameter treatment costs included in the calculations.
