Flooding threatened to turn the dross stored in a old Southland paper mill into toxic waste last week, leaving residents of Mataura desperate to see the aluminum smelting byproduct gone.
During the floods, Rio Tinto told the council it would speed up the removal.
But the company that owns the Tiwai Point aluminium smelter has since reneged on the handshake deal, leaving residents of Mataura furious.
Many residents were evacuated last week because of fears flooding could have soaked the waste product, ouvea premix, and released a highly dangerous cloud of ammonia gas.
