- 22. IAQM Guidance DustJohn Salmon •“The operational phases of minerals (and some waste) sites share some common features with construction activities; however minerals sites can be significantly larger scale. A qualitative dust assessment for a minerals site would normally be expected to be at least as rigorous as one carried out in accordance with the IAQM construction dust method, reflecting the potential for mineral sites to have a greater impact than construction sites” (IAQM Guidance 2014)
