The original plans included an Environmental Impact Statement that required a tailings dam be built. This would allow heavy metals and solid particles to settle, before releasing the less polluted ‘high-water’ into the river system where remaining contaminants would be diluted. In 1984 an earthquake caused the half-built dam to collapse. The company continued operations without the dam, initially because BHP argued that it would be too expensive to rebuild it. Subsequently, the Government of Papua New Guinea decided a dam was not necessary, in the wake of the closure of the Panguna mine.[citation needed]
