Local state of emergency declared after B.C. tailings pond wall collapse

Written By Unknown on Rabu, 06 Agustus 2014 | 21.48

A local state of emergency has been declared in an area where a B.C. tailings pond wall collapsed, sending billions of litres of mine waste water and millions of cubic metres of metals-laden sand into local waterways.

The Cariboo Regional District (CRD) made the declaration roughly 48 hours after the Mount Polley mine's pond wall breached.

In a post on its emergency operations department's Facebook page, the CRD said the local state of emergency status would help it "access additional capacity that may be necessary to further protect the private property and government infrastructure in the town of Likely."

Brian Kynoch, president of mine owner Imperial Metals, told CBC News on Wednesday morning that water was still flowing from the pond, despite that fact it's virtually empty.

Work crews were out all night trying to close the dam and secure the debris flow areas, he said.

Kynoch said he expected Imperial Metals would brief provincial officials at 1 p.m. PT Wednesday, and may have more information to release then.

The exact composition of the pond water released into the environment is not known, but water samples collected by staff from B.C.'s Environment Ministry have been sent for analysis.

On Tuesday, Imperial Metals said the tailings water was "very close to drinking water quality" and had only very low levels of arsenic and other metals.
