Regional smoke from prescribed burn-offs and bushfires can elevate particulate levels. Smoke-affected periods are denoted by the shaded (grey) area on the graph to clearly distinguish them from conditions influenced by site operations. We are required to report all exceedances of the 24-hour rolling average limit to regulators. Each exceedance is assessed to determine whether site activities contributed, and the outcomes of these assessments are clearly communicated. As at (auto-updated date), no exceedances of the regulated 24-hour rolling average have been attributed to Talison operations in 2026. This page will be updated should any operationally attributable exceedances occur.
