Mining and coal organisations report, by river basin, how many tailings dams they control, active and inactive; state whether they evaluate and classify dams by the consequences of failure to human health and ecosystems and the guidelines used; give details of each dam rated hazardous or highly hazardous; and describe the procedures in place to manage potential impacts on human health and water ecosystems (for example acceptable risk levels, operating plans, emergency preparedness and independent review).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
