The federal government has released its plan for the first 10 years of a massive cleanup project of a century's worth of mining pollution in Idaho's Silver Valley.

The federal government has released its plan for the first 10 years of a massive cleanup project of a century’s worth of mining pollution in Idaho’s Silver Valley.

The U.S. Environmental Protection Agency earlier this week released for public comment the plan that identifies priority work over the next decade to clean up arsenic, lead and other heavy metals pollutants in the valley in northern Idaho.

The Coeur d’Alene Press reports (http://bit.ly/TzhLBz) the plan includes upgrading the Kellogg groundwater treatment plant and cleaning up the East Fork of Nine Mile Creek.

The Coeur d’Alene River Basin is one of the nation’s largest Superfund sites, with heavy metals poisoning land, streams, wildlife and humans. The wastes washed into waterways and moved downstream, some extending into the state of Washington.
