BRASILIA, Nov 27 (Reuters) - Brazil's environmental regulator is planning additional fines against iron ore miner Samarco on top of the 20 billion reais in damages and clean-up charges the government is seeking, the country's attorney general, Luis Adams, said on Friday.
The regulator, known as Ibama, has already fined Samarco 250 million reais in the aftermath of a rupture of a tailings dam that ravaged communities and contaminated a major river.
Samarco is a joint venture between the world's largest mining company, BHP Billiton Ltd , and the biggest iron ore miner, Vale SA . (Reporting by Alonso Soto; Editing by Leslie Adler)
