ANNEX IIIEMISSION LIMIT VALUES FOR SO2
Solid fuel
A.
SO2 emission limit values expressed in mg/Nm3 (O2 content 6 %) to be applied by new and existing plants pursuant to Article 4(1) and 4(3) respectively:
NB.
Where the emission limit values above cannot be met due to the characteristics of the fuel, a rate of desulphurisation of at least 60 % shall be achieved in the case of plants with a rated thermal input of less than or equal to 100 MWth, 75 % for plants greater than 100 MWth and less than or equal to 300 MWth and 90 % for plants greater than 300 MWth. For plants greater than 500 MWth, a desulphurisation rate of at least 94 % shall apply or of at least 92 % where a contract for the fitting of flue gas desulphurisation or lime injection equipment has been entered into, and work on its installation has commenced, before 1 January 2001.
B.
SO2 emission limit values expressed in mg/Nm3 (O2 content 6 %) to be applied by new plants pursuant to Article 4(2) with the exception of gas turbines.
Type of fuel | 50 to 100 MWth | 100 to 300 MWth | > 300 MWth |
---|---|---|---|
Biomass | 200 | 200 | 200 |
General case | 850 | 20021 | 200 |
Except in the case of the ‘Outermost Regions’ where 850 to 200 mg/Nm3 (linear decrease) shall apply. |
NB.
Where the emission limit values above cannot be met due to the characteristics of the fuel, installations shall achieve 300 mg/Nm3 SO2, or a rate of desulphurisation of at least 92 % shall be achieved in the case of plants with a rated thermal input of less than or equal to 300 MWth and in the case of plants with a rated thermal input greater than 300 MWth a rate of desulphurisation of at least 95 % together with a maximum permissible emission limit value of 400 mg/Nm3 shall apply.
