Bauxite Residue Land Requirements

We conduct a risk assessment and develop an operational plan for each location. We review and update both of these as appropriate throughout the facility’s lifecycle.

Our risk assessment considers the following:

  • Physical and chemical risk of the impoundment facility;
  • Environmental risks, including earthquakes, droughts and heavy rainfall, that could impact the facility and its operation; and
  • Other risks external to Alcoa and the facility, including regulatory and permitting risks.

The operational plan identifies mitigation and control measures to eliminate or avoid risk to the extent practicable; reduce risk by minimizing the likelihood or potential consequence of an unwanted event or condition that poses a risk; and detect, respond to and minimize the consequences if an unwanted event or condition occurs that poses a risk.

    Dam Break Drill Boosts Emergency Preparedness
