UPDATE 2-Canada environmental officers raid Vale offices in Ontario

(Adds confirmation, details from Environment Canada)
Oct 9 (Reuters) - Environment Canada raided one of mining
giant Vale SA's VALE5.SA Sudbury, Ontario offices on Thursday,
investigating allegations that the company violated the
Fisheries Act in 2012, the company said on Friday.
Environment Canada confirmed that its enforcement officers
executed a search warrant with support from the Royal Canadian
Mounted Police, part of an active investigation that started in
November 2012.
"The investigation relates to alleged violations of the
general prohibition in the Fisheries Act, which prohibits the
deposit of substances that are deleterious to fish into water
frequented by fish," said spokeswoman Natalie Huneault in an
emailed statement.
Vale spokesman Cory McPhee said the company is cooperating
with the investigation.
"I can confirm that Environment Canada was on-site at one of
our Sudbury offices on Thursday collecting information related
to alleged violations of the Fisheries Act that allegedly
occurred in 2012," he said in an emailed statement.
Vale spokeswoman Emily Robb said there was no impact on
Vale's operations.
"The matter under investigation never posed a threat to
health and safety in our community," Robb said in an emailed
statement, adding that Vale addressed the issue in 2012 and that
it had communicated with regulators.
"We believed then, and believe now, that our actions were
appropriate and responsible," she said.
The Brazilian-based company's Canadian operations have
suffered a number of safety incidents in recent years.
In August, a nitrogen oxide leak sent a yellow plume up from
the Copper Cliff nickel and copper smelter in Sudbury, forcing
the company to declare an emergency. There were no injuries.
In 2013, Vale was fined C$1.05 million for an incident that
killed two workers at the Stobie mine, also in Sudbury.
In April 2014 another worker died at Copper Cliff's casting
and crushing plant. Ontario laid health and safety charges
against the company in March of this year.
