BHP faces water use lawsuit brought by Chilean state

A Chilean environmental court said on Tuesday it would investigate a complaint brought by the government against global miner BHP over allegations of damage to the northern Punta Negra salt flat.

The First Environmental Court, based in the northern Chilean city of Antofagasta, said the complaint was brought by the State Defense Council against BHP. The complaint described "continuous, cumulative, permanent and irreparable environmental damage" to the salt flat, 170 km southeast of Antofagasta.
