Article 31 2.

For combustion plants firing indigenous solid fuel, which co-incinerate waste, and which cannot comply with the Cproc values for sulphur dioxide set out in points 3.1 or 3.2 of Part 4 of Annex VI due to the characteristics of the indigenous solid fuel, Member States may apply instead the minimum rates of desulphurisation set out in Part 5 of Annex V, in accordance with the compliance rules set out in Part 6 of that Annex. If Member States choose to apply this paragraph, Cwaste as referred to in point 1 of Part 4 of Annex VI shall be equal to 0 mg/Nm3.
