Brazil says Vale, BHP Billiton presented plans for Rio Doce recovery

BRASILIA (Reuters) - Miners Vale SA and BHP Billiton Ltd have presented plans for recovery of the Rio Doce river after a dam burst at their iron ore venture unleashed toxic mud in November, Brazil's Environment Minister Izabella Teixeira said on Monday. Teixeira said the government had estimated 20 billion reais ($5 billion) were needed to clean up the river but did not say how much the companies had offered to pay. She said progress had been made on the negotiations, however. (Reporting by Maria Carolina Marcello; Writing by Caroline Stauffer; Editing by Meredith Mazzilli)
