State environmental regulators have proposed new rules to protect the water quality in Lake Koocanusa and the Kootenai River, which span the international border and have registered a steady increase in a toxic pollutant leaching downstream from Canadian coal mines and into Montana’s prized lakes and rivers.

The proposed rules are nearly four times more stringent than current federal regulations and more than six times more stringent than state regulations.

The Montana Board of Environmental Review initiated a formal rulemaking process to establish site-specific water quality standards for a pollutant called selenium in Lake Koocanusa and the Kootenai River. The decision follows a request made by the Montana Department of Environmental Quality (DEQ).
