Task 2 Review of, and assistance with, SSB’s Rehabilitation Standard for sulfate. – Background is a need to develop a Rehabilitation Standard for sulfate in the context of ongoing issues associated with acid sulfate soils (ASS). Drafting of such a document has ‘mine-generated’ commenced, but requires specialist ASS expertise to be completed. SSB does not have such expertise and this project will inform the rehabilitation standard. Moroever, is a need to review ERA’s recent studies on ASS in Coonjimba Billabong, where significant acid events have been occurring in the early wet season since 2012.
