4.

The emission limit values shall apply at the point where waste waters from the cleaning of exhaust gases containing the polluting substances referred to in Annex IV are discharged from the incineration or co-incineration plant. Where the waste water from the cleaning of exhaust gases is treated on site collectively with other on-site sources of waste water, the operator shall take the measurements referred to in Article 11: on the waste water stream from the exhaust gas cleaning processes prior to its input into the collective waste water treatment plant; on the other waste water stream or streams prior to its or their input into the collective waste water treatment plant; at the point of final waste water discharge, after the treatment, from the incineration plant or co-incineration plant. The operator shall take appropriate mass balance calculations in order to determine the emission levels in the final waste water discharge that can be attributed to the waste water arising from the cleaning of exhaust gases in order to check compliance with the emission limit values set out in Annex IV for the waste water stream from the exhaust gas cleaning process. Under no circumstances shall dilution of waste water take place for the purpose of complying with the emission limit values set in Annex IV.
