Return to Use Initiative
2006 Demonstration Project
California Gulch: Leadville, CO
THE SITE: The California Gulch Superfund Site in Lake County, Colorado,
encompasses more than 18 square miles in the Rocky Mountains, about
120 miles west of Denver. Mining, mineral processing, and smelting
activities there produced gold, silver, lead, copper, manganese, and zinc
for more than 130 continuous years. The site was listed on the National
Priorities List in 1983, primarily because of acid mine drainage from
the YakTunnel, mine waste piles, and tailing ponds that contaminated
ground water and caused surface water pollution in the California
Gulch area and the Arkansas River. Nearly all of the mines within the
California Gulch site boundary are presently inactive, and all of the
mills and smelters have been either decommissioned or demolished.
Many areas within the site are still undergoing continuing remedial
activities, but some of the cleaned up portions of the site are already in
reuse. The Robert Emmet Mine section of the site received a Superfund
Redevelopment Initiative cooperative agreement in 2001.
THE OPPORTUNITY: Currently, children registered in the Lake County
Youth Soccer league play their games in a town 35 miles away. Leadville's
adult teams regularly travel 40 miles for games. To alleviate such
commuting, Leadville citizens on the Lake County Recreation Advisory
Board aim to establish a recreational facility for soccer and other
activities. A portion of the site near Leadville's downtown area could be
an ideal location for the recreational facility. The United States Soccer
Foundation, one of EPA's national partners, awarded a $10,000 grant to
develop conceptual plans for the future Lake County Community Park.
With the plan completed, the group is seeking additional funding for
construction of the complex.
THE BARRIERS: The portion of the site targeted for the recreational
complex currently contains mining slag. Construction activities will
require grading and capping of the sharp slag material. EPA will
coordinate with stakeholders to ensure that human health and the
environment are protected. Another complication is that the site's
long history has made county officials and community members wary.
The stigma associated with the site creates a powerful deterrent to its
reuse.
THE SOLUTION: To help shape a new image and to assure members
of the local community that safe reuse is a realistic possibility, EPA is
helping to facilitate and maintain an open dialogue among the local
Superfund Redevelopment Initiative
Barriers:
Proposed reuse construction
requiring EPA oversight;
Superfund site stigma
Solution:
Construction monitoring by EPA
to ensure protection of human
health and the environment;
facilitating and maintaining
an open dialogue among
stakeholders to address concerns
Before:
Part of an 18-square mile
mining site in a former mining
community in the Rocky
Mountains
After:
Proposed recreational complex
that ties into local mining
heritage and historical trail
and complements an ongoing
community revitalization effort

government, members of the Leadville community, the U.S. Soccer Foundation, and regulatory agencies.
Regular communication is helping to eliminate confusion and misconceptions about reusing Superfund sites
by ensuring that the remedy will be safe for children to participate in sports on this portion of the site.
THE SITE NOW: As fundraising and planning for the project progress,the stakeholders will establish a process
to seek the views of the community. The completed recreational facility will include a trail extension to link
to the Mineral Belt TraiI, a 12.5-mile paved trail that loops the City of Leadville, passes through historic mining
areas, and offers stunning views of the Rocky Mountains. The Mineral Belt Trail is an important part of the
existing reuse at other areas of the site. Local residents hope that the future complex will be a valued asset
and an economic enhancement for the community just as the trail has been in recent years.
