Settlement Resolves One of the Largest Superfund Cases Ever Filed

Date Posted: June 13, 2011

A settlement has been reached with Hecla Mining Company to resolve one of the largest cases ever filed under the Superfund statute.  Under the settlement, Hecla will pay $263.4 million plus interest to the United States, the Coeur d’Alene Tribe and the state of Idaho to resolve claims stemming from releases of wastes from its mining operations.  Settlement funds will be dedicated to restoration and remediation of natural resources in the Coeur d’Alene Basin. The agreement, which was lodged in federal district court in Idaho today, brings closure to that lawsuit and establishes a strong basis for future cooperation between Hecla and the governments in the Coeur d’Alene Basin.

The Bunker Hill Superfund site is one of the nation’s largest and most contaminated Superfund sites.  At one time, the Upper Basin, or Silver Valley, was one of the largest silver producing districts in the world.  As a result, the basin has been contaminated by the release of metals like lead and arsenic, which are widespread.  EPA began cleanup at the site in the 1980s, focusing on protecting human health.  Although measurable improvements in public and environmental health have been achieved, widespread contamination remains a challenge and cleanup work will continue for many years.
“This settlement provides substantial funding that the trustees will use to restore habitat for fish, birds and other natural resources that have been injured for many decades by mining wastes,” said Rachel Jacobson, Acting Assistant Secretary for Fish, Wildlife, and Parks at the U.S. Department of Interior.
