San Francisco Bay Fund Inventory of Projects

Developing a Methodology for Clean Up of Abandoned Mines Project

Organization: Sustainable Conservation
2008 Grant Recipient – Contra Costa County

Purpose

More than 47,000 abandoned mines exist in California - with more than 5,000 presenting environmental hazards. Sustainable Conservation evaluated the costs and benefits of voluntary cleanups at abandoned mines in the western U.S. - and produced a case comparison between a voluntary cleanup done in Utah under the federal Good Samaritan Initiative, and a voluntary cleanup proposed in California.

Sustainable Conservation's study reviewed the legal and engineering methodologies used by a non-profit organization, four federal agencies and two private companies to clean up the Pacific Mine along Utah's American Fork Canyon River. The Utah experience is then compared to the circumstances surrounding the proposed cleanup of the abandoned Mount Diablo Mercury Mine along California's Marsh Creek (in Contra Costa County). A series of detailed conclusions and recommendations distilled the lessons learned to date in Utah and California, and provided stakeholders with options for advancing a voluntary cleanup of the Mount Diablo Mercury Mine.

2012 Update

The study provides compelling insight into how the Good Samaritan Initiative has been, and could be used successfully in the West to empower voluntary actions that protect the environment and people.
