E. Blackbird Mine CERCLA Site<br />
Site: Blackbird Mine consists of more than 10,000 acres of mining claims in Salmon<br />
National Forest, which is in east central Idaho, 20 miles west of the town of Salmon, Idaho.<br />
There are mine tunnels, waste rock piles, <strong>and</strong> a 10.5 acre open pit at the headwaters of Bucktail<br />
<strong>and</strong> Meadow Creeks, which drain into Big Deer <strong>and</strong> Blackbird Creeks, which in turn drain into<br />
Panther Creek, a major tributary of the Salmon River. Cobalt <strong>and</strong> copper mining began at the<br />
site in the late 19 th century <strong>and</strong> mining activity peaked in the 1940s <strong>and</strong> 1950s. By 1982, the<br />
current owner, the Nor<strong>and</strong>a Mining Company, had ceased operations.<br />
Release: Copper, cobalt, arsenic, <strong>and</strong> other hazardous materials have leached out of the<br />
mine tunnels <strong>and</strong> waste rock piles <strong>and</strong> into the watershed. Surface water <strong>and</strong> sediment in the<br />
creeks contain high levels of these contaminants.<br />
Injury: There has been no accurate measure of the quantities of contaminants due to the<br />
protracted nature of the release. However, the hazardous substances leached into the waters of<br />
Panther Creek <strong>and</strong> into the surrounding watershed, contaminating surface water <strong>and</strong> sediments in<br />
the creeks.<br />
Panther Creek had historically supported substantial runs of Chinook salmon. By the<br />
early 1960s, these fish had been completely eliminated from Panther Creek by contamination<br />
from the Blackbird Mine. The sockeye <strong>and</strong> Chinook salmon <strong>and</strong> the Steelhead <strong>and</strong> Bull trout<br />
downstream in the Salmon River are threatened by the poor water quality. The populations of<br />
other species of fish have also been reduced. The Idaho Department of Fish <strong>and</strong> Game found<br />
that the population density of rainbow trout in Panther Creek upstream from the mining influence<br />
were 35 to 50 times higher than in the part of that stream most directly affected by the mine.<br />
Attachment of Liability: NRDs are permitted under both CERCLA <strong>and</strong> CWA because<br />
of the “release” or “discharge” of a hazardous substance into the waters of the adjoining<br />
shorelines of the United States or into a contiguous zone of the United States.<br />

<strong>Damage</strong>s: The reduction of fish populations entails some injury in the form of lost<br />
ecosystem services. There are also damages due to the recreational activity surrounding Panther<br />
