    Emission Standard for Power Plant with Mixed Fuel
    In case of a power plant utilizing mixed fuel (mixture of various types of fuel) in each generating unit, emission standard values must be calculated base upon the ratio of each type of fuel as follow:

    Emission Standard = AX + BY + CZ

    A = Emission Standards for utilizing only coal as fuel
    B = Emission Standards for utilizing only oil as fuel
    C = Emission Standards for utilizing only gas as fuel
    X = Ratio of Heat Input from utilizing only coal as fuel
    Y = Ratio of Heat Input from utilization only oil as fuel
    Z = Ratio of Heat Input from utilization only gas as fuel
