BRASILIA/RIO DE JANEIRO March 2 (Reuters) - Mining company Samarco and its owners, BHP Billiton and Vale SA , reached a deal with the Brazilian government on Wednesday to pay an estimated 20 billion reais ($5.1 billion) in damages over 15 years for a deadly dam spill in November.
Considered Brazil's worst environmental disaster, the burst tailings dam in the state of Minas Gerais killed 19 people, left hundreds homeless and polluted a major river.
Of the total, Samarco will pay 4.4 billion reais through 2018 into a fund to cover the cleanup of the spill from the tailings dam. From 2019 to 2021, payments will be between 800 million reais and 1.6 billion reais.
"We want to build new life on the rubble of an unprecedented tragedy," President Dilma Rousseff said at the signing ceremony in Brasilia.
Beyond 2021, the amount will be decided depending on how much work remains to be done. The government estimates the total cost of the lengthy environmental plan, including replanting and dredging, will reach about 20 billion reais.
The 20 billion reais figure was, however, noticeably absent from statements sent by Samarco, BHP and Vale. The obligations outlined by the companies instead came to about 12 billion reais. The difference, the government explained, was due to estimates of amounts that can be only decided in the future.
"This is not about a dollar amount, this about a program to remediate, to restore and where we can't restore to compensate and also to leave some positive legacies behind," Dean Dalla Valle, BHP's Chief Commercial Officer, told Reuters at the ceremony.
"Besides straight remediation, we are talking about actions like sewage, landfill, reforestation, water treatment," he said.
Vale, in a statement, said that in the event Samarco is unable to pay its obligations, Vale and BHP would be responsible for covering the costs.
The miner said the accord does not cover private civil suits, other public civil suits or criminal investigations.
Preferred shares in Vale were trading 7.5 percent higher following the announcement, boosted on the accord and a rise in iron ore prices.
Dalla Valle said he hoped Samarco would be in a position to restart its mine in the final quarter of the year. The company has already taken the first steps to get its licenses in place to restart.
"We will only start when it is absolutely safe, we will need to learn from the investigation. The way it will start won't involve the current tailings dams," Dalla Valle said.
