Table 27

BAT-associated emission levels (BAT-AELs) for channelled dust emissions to air from starch, protein and fibre drying

Parameter	Unit	BAT-AEL (average over the sampling period)
When a bag filter is not applicable, the upper end of the range is 20 mg/Nm³.
Parameter	Unit	New plants	Existing plants
Dust	mg/Nm³	< 2-5 ^f1	< 2-10

The associated monitoring is given in BAT 5.
