MARIANA, Brazil (Reuters) - Brazil’s government said on Wednesday it may fine mining giants BHP Billiton Ltd and Vale SA for the “environmental catastrophe” caused by ruptured dams at an iron ore mine jointly owned by the companies in a southeastern state.
The government is increasingly concerned over the rising death toll and contaminated mud flowing through two states as a result of the disaster. It is studying the mine’s permits and will ensure the owners pay for cleanup costs, Environment Minister Izabella Teixeira said in Brasília, the capital.
“If federal fines are applicable, we will apply them,” Teixeira told reporters. “There will be punishment, and under Brazilian law the environment has to be repaired.”
Her remarks are the strongest yet from the government, which was caught off-guard by a disaster that killed at least eight people and left another 21 missing in the mineral-rich state of Minas Gerais nearly a week ago.
The warning came as the chief executives of Australia-based BHP, the world’s largest mining company, and Brazil’s Vale, the world’s biggest iron ore miner, took responsibility for the disaster.
After surveying the devastated area together, BHP CEO Andrew Mackenzie and Vale CEO Murilo Ferreira told a news conference their companies would meet all their obligations as joint owners of the mine, which is formally run by Samarco Mineração SA[SAMNE.UL].
They said BHP and Vale would create a joint fund for the recovery costs, but added that it was too soon to calculate how much would be needed. They also reaffirmed their long-term commitment to the joint venture.
“We are 100 percent committed to do everything we can do to support Samarco and make this right,” Mackenzie said. “We are deeply sorry for everyone who has or will suffer for this terrible tragedy.”
The apologies, however, are not doing much to calm nerves. More than 500 people remain displaced because of destroyed homes, and recovery crews are slogging through nearly 100 km (62 miles) of mud-caked floodplain in a search for more victims.
Fernando Pimentel, the governor of Minas Gerais, said on Wednesday the companies were not doing enough to address the problems caused by the disaster, including the interruption of water service for hundreds of thousands of residents downstream.
Water from the dams that burst contained mining residue known as tailings.
“Samarco, to blame for all of this, will have to make a greater effort,” Pimentel told reporters in Governador Valadares, a city of 300,000 residents that is now having its water trucked in.
President Dilma Rousseff, who will fly over the disaster area on Thursday with Teixeira, believes the mining companies must pay for the cleanup of devastated and flooded villages and the restoration of water supplies, a presidential aide said.
The Brazilian leader telephoned Ferreira and Mackenzie on Wednesday, Brazil’s national integration minister Gilberto Occhi told reporters on Wednesday.
Known for her harsh reprimands of opponents and subordinates, Rousseff told the CEOs that she expected Vale and BHP to cover all environmental and reconstruction costs as well as pay compensation to displaced families.
The conversation was “tough”, a presidential press aide told Reuters. To reinforce her message, Rousseff asked her chief of staff, Jaques Wagner, to meet with the companies’ executives.
Mackenzie flew to Brazil this week as Ferreira came under increasing fire from local authorities, residents and media for what many saw as a laconic response to one of the South American nation’s worst mining disasters.
Neither the companies nor Brazilian officials have determined a cause for the ruptures, though Samarco acknowledged that workers, 13 of whom were washed away by the torrent, were engaged in an expansion of the first dam when it burst. The work was necessary because of increased output at the mine.
A state prosecutor on Wednesday said investigators are probing reports that Vale contributed to higher water volumes behind the dam by sending waste from one of its nearby mines to Samarco’s tailings pond. When a reporter asked about the reports at the news conference, the executives did not answer.
The disaster has become a public relations, regulatory and financial nightmare for the companies. Politicians, environmentalists and residents are calling for tougher rules on the mining industry, which employs hundreds of thousands of people and is a major source of export revenue.
In addition to the financial costs due to lost output and repairs at the mine, which accounts for about 10 percent of Brazil’s iron ore exports, BHP and Vale are expected to face steep fines as well as lawsuits at a time when iron ore prices are at their lowest point in a decade.
A person familiar with the insurance framework around the mine said on Tuesday that the disaster could trigger $600 million in insurance claims.
In the days after the dam burst last Thursday, Vale, a company with decades of mining experience in the area, made only a brief statement and referred all inquiries to Samarco. Though Ferreira made a visit to the mine over the weekend, he did so quietly and without disclosing the trip until BHP announced Mackenzie was en route.
In response to the growing public criticism, Vale on Tuesday said it had “supported Samarco since the first day” of the disaster and had provided 100 employees, helicopters, fuel and vehicles to the recovery effort. On Wednesday, Ferreira said he did not see the need to publicize his first visit to the area because he did not want to speak on behalf of Samarco.
The mine employs about 1,800 workers, most of whom are now on paid leave as operations have been halted.
