Division EMISSION LEVELS ASSOCIATED WITH BAT

Where emission levels associated with the best available techniques (BAT-AELs) are given for the same averaging period in different units (e.g. as concentration and specific load values (that is per tonne of net production)), those different ways of expressing BAT-AELs are to be seen as equivalent alternatives.

For integrated and multi-product pulp and paper mills, the BAT-AELs defined for the individual processes (pulping, papermaking) and/or products need to be combined according to a mixing rule based on their additive shares of discharge.
