# Commission Implementing Decision of 28 February 2012 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for iron and steel production (notified under document C(2012) 903) (Text with EEA relevance) (2012/135/EU), Division 79

Extent: E+W+S+N.I.

BAT for on-site slag processing is to reduce dust emissions by using one or a combination of the following techniques:
I.. efficient extraction of the slag crusher and screening devices with subsequent off-gas cleaning, if relevant
II.. transport of untreated slag by shovel loaders
III.. extraction or wetting of conveyor transfer points for broken material
IV.. wetting of slag storage heaps
V.. use of water fogs when broken slag is loaded.
The BAT-associated emission level for dust in the case of using BAT I is < 10 – 20 mg/Nm3, determined as the average over the sampling period (discontinuous measurement, spot samples for at least half an hour).
