S.L. 549.78 Art. 14Multi-firing units.

Permits for combustion plants made up of multi-firing units involving the simultaneous use of two or more fuels shall include conditions relating to compliance with emission limit values which shall be established as follows:

(a) by taking the emission limit value relevant to each individual fuel and pollutant corresponding to the rated thermal input of the combustion plant as given in Schedules I, II, III, IV, V and VI as applicable;

(b) by determining fuel-weighted emission limit values, which are obtained by multiplying the above individual emission limit value by the thermal input delivered by each fuel, the product of multiplication being divided by the sum of the thermal inputs delivered by all fuels; and

(c) by aggregating the fuel-weighted limit values.
