(Replaced, O.C. 501-2011)Recuperated dust: Dust recuperated by a dry collector must be handled and transported so that there is no dust released into the atmosphere which can be seen 2 metres from the emission source. When it is not recycled, it must be stored, spread or disposed of on the ground and the necessary measures must be taken to prevent any release of dust into the atmosphere which can be seen 2 metres away from the emission source, and in order to prevent water contamination.
