(Denver, Colo. - March 19, 2008) The U.S. Environmental Protection Agency is proposing the addition of the Nelson Tunnel/Commodore Waste Rock site near Creede, Colo., to the National Priorities List (NPL) of Superfund sites. The draining mine adit and waste rock pile are located about one mile above the town of Creede in Mineral County, Colo. Today's announcement begins a sixty-day period in which citizens may send comments on the proposed listing to EPA.
The historical mining of silver, lead, and zinc in the Creede mining district resulted in contaminated water discharging into the Willow Creek drainage and mine waste piles accumulating in the watershed. The Nelson Tunnel adit drainage is the largest source of cadmium, lead and zinc in the Willow Creek watershed.
The Commodore Waste Rock pile also contains elevated levels of arsenic, cadmium, lead, and zinc. The drainage constructed around the pile failed in 2005 during a flood which left the Commodore Waste Rock pile highly unstable. The pile lies primarily in West Willow Creek, but during the flood some of the rock was washed downstream into Willow Creek. The potential exists for these piles to contaminate the town of Creede during another flood.
A biological assessment of the Willow creek watershed indicated concentrations for cadmium, lead and zinc that exceed recommended dietary intake benchmarks and aquatic water standards for fish and birds. These analyses identified cleanup of the Nelson Tunnel as a key element to restoring the Willow Creek stream and streamside habitat.
Christiansen said the National Historic Preservation Act requires federal agencies to take into account the effects of their undertakings on historic properties on and around the site.
The NPL is a published list of sites in the United States that are contaminated by hazardous substances and eligible for extensive, long-term cleanup under the Superfund program. Listing on the NPL makes a site eligible to receive federal funds for cleanup while EPA seeks to recover costs from identified responsible parties, if any. Placing a site on the NPL also allows EPA to use Superfund money for cleanup when there are no responsible parties who can pay for the work.
Listing this site on the NPL guarantees the public an opportunity to participate in cleanup decisions. Affected communities are also eligible for technical assistance grants from the EPA to help facilitate understanding technical documents and provide for community involvement at the site. Information that EPA used to document the proposed listing of the site is available at:www.epa.gov/region8/superfund/co/nelsoncommodore
