Washington Undermined: The Toxic Legacy Of Abandoned Metal Mines In Washington State

7/7/2004

Executive Summary

A century of mining in Washington has left a legacy of 3,800 abandoned hardrock mine sites scattered throughout the state. These abandoned mines pollute our streams and rivers, pose a threat to public safety and health, destroy fisheries, and contaminate important groundwater resources.

Lead, mercury and other heavy metals leaching from mine sites build up in the environment. Every day, Washington watersheds receive a new dose of arsenic and toxic run-off from abandoned mines. Unless stopped, this pollution can continue indefinitely. Unfortunately, many of the corporations responsible for the contamination and liable for cleanup costs have dissolved or gone bankrupt.

Today, state and federal agencies in Washington face the challenge of addressing abandoned mine safety and environmental issues at a time of limited agency resources and potential budget cuts, and without a comprehensive inventory of mining sites in the state.

While some information on abandoned mines lands is available from state, local and federal agencies, there has not yet been an adequately funded, statewide coordinated effort to address abandoned mine lands in Washington, nor a completed central database of all abandoned mine information in the state. According to a 2000 Department of Ecology report, there is "almost no data available to evaluate the extent of the problem."

The risks associated with this lack of knowledge may increase as the state's population moves into high-density abandoned mine areas such as the Cascade Foothills in Snohomish County and the Okanogan Highlands. The longer this problem is left unaddressed, the worse the contamination will be, and the more likely it is that taxpayers, rather than the polluting industry, will be forced to fund the clean up.

The purpose of this report is to provide a comprehensive picture of the extent of the abandoned mine land problem in Washington, to set forth what has been done thus far to address the problem, and to point out what should be done in the future to ensure adequate funding and a more efficient allocation of resources for the inventory and clean up of these sites.

Program Recommendation: To adequately protect human health and the environment, the WashPIRG Foundation recommends that federal and state land management agencies work together to:

- Establish an interagency Abandoned Mine Task Force
Only by coordinating efforts can the various agencies effectively address the cumulative impact from mining contamination on various state and federal lands within a watershed. Moreover, coordination of efforts may ensure that maximization of scarce resources, and reduce costly duplication of effort.

- Complete an inventory of the 541 most significant abandoned mines
The Abandoned Mine Task Force should allocate all available resources to completion of the inventory of the state's 541 most significant mines. The inventory should be completed at the earliest possible date to ensure that currently viable companies liable for the pollution do not dissolve or become bankrupt before they are identified and held accountable. Agencies should make the information in this inventory available to the public and conduct outreach danger in the most highly impacted communities to warn citizens of any potential public health risks.

- Apply available funds to coordinate cleanup efforts by watershed
The Task Force should prioritize, watershed by watershed, specific water bodies within each state that are affected by discharges from the identified mines. This "watershed approach" should be a collaborative effort in recognition of the potential for combined impacts on watersheds resulting from runoff from mines on federal, state and tribal lands. Once these watersheds are prioritized, agencies should proceed with a coordinated watershed cleanup program.

Funding Recommendation: To fund this effort, WashPIRG Foundation joins dozens of organizations across the Western States to recommend federal legislation that would:

- Establish a national variable reclamation fee on large scale mineral producers, based on the producer's profits from mineral extraction on federal land;

- Create a trust fund with these fees, which would help pay for both the initial inventory and the cleanup of abandoned hardrock mines across Washington and the other western states.
