The practice of using emulsions has generally been phased out with ongoing licence reviews. A brief overview undertaken in response to this question indicates that the DEP endorses the use of water-based emulsions containing waste oil only within the lined and bunded residue disposal areas at the Alcoa facilities. (4) The DEP is not aware of any adverse impacts associated with the use of water-based waste oil emulsions at the Alcoa facilities. (5) A wide variety of chemical-based dust suppressants, ranging from saline water to proprietary products, are used in Western Australia.
