A provision in the recent federal budget bill requires the EPA to get off the dime and work with U.S. and Canadian agencies to do something about mining waste in the Kootenai Watershed . . .

Stemming the flow of dangerous mining contaminants spilling from Canada into the Kootenai River watershed was listed as a priority in the 2,232-page government-spending bill signed by President Donald Trump, marking a hard-won victory for advocates of the endangered river and the communities it supports.

Inclusion of the beleaguered river system in the massive spending bill is another in a recent series of significant steps toward tackling a decade-long problem brewing in the transboundary Kootenai River watershed, where toxic contaminants leaching from upstream Canadian coal mines in the Elk River Valley of British Columbia continue to threaten Montana’s prized aquatic ecosystems.

Spearheading the latest charge to bring attention to the Kootenai is U.S. Sen. Jon Tester, D-Montana, who helped draft the annual budget bill as a member of the powerful Senate Appropriations Committee, and who for years has been mounting pressure on the U.S. and B.C. governments to develop a bilateral water quality standard for mining contaminants, including selenium, sulfates and nitrates.

Yet another object lesson on why it is so important to protect the transboundary Flathead Watershed . . .

As British Columbia’s downstream neighbor, Montana has long been concerned about mining pollution spilling across the international border and into its world-class watersheds — fears that a growing body of research and evidence confirms are well founded.

Most recently, conservation groups and scientists on both sides of the border have renewed their calls for Teck Resources to halt new coal mines in the Elk River Valley, a step they say gained urgency when an experimental water treatment facility designed to stem the flow of a mining contaminant called selenium was taken offline because it was releasing an even more biologically toxic form of the heavy metal.

The trouble brewing in the Elk River is equally worrisome for Montana, where the upstream waterways of British Columbia flow into two shared bodies of water straddling the international boundary — Lake Koocanusa and the Kootenai River.
