RIO DE JANEIRO, Jan 19 (Reuters) - Brazilian prosecutors in
the state of Minas Gerais said on Wednesday that 18 tailings
dams at mines run by Vale require some work to
guarantee their safety following heavy rains in recent months.
In a statement, state prosecutors said an analysis of 31
dams had revealed the need for the preventative measures,
although they stressed there was no direct damage to the highest
"Based on the data provided, 18 dams were found to present
issues that must be resolved to avoid problems with the
functioning of the structures," prosecutors said, adding that
all the 18 dams were run by Vale.
Prosecutors said Vale would have 10 days to present a report
informing what action it would take.
Vale, in response to a request for comment, said it was
conducting detailed evaluations of its dams to make necessary
improvements, particularly looking at the issue of access which
had been impacted by the rains.
