Audit finds hazards from abandoned mines

updated 9:01 p.m. ET July 25, 2008

WASHINGTON - The government has endangered the public's health and safety by failing to clean up abandoned mines on federal land in the West, according to a scathing audit released Friday.

The Interior Department's inspector general found dangerous levels of arsenic, lead and mercury, along with gaping cavities, at dilapidated hard-rock mining sites easily accessible to visitors and residents.

Bureau of Land Management supervisors told staff to ignore the problems, and employees who tried to report contaminated sites were threatened with retaliation, the audit said.

At least 12 people were killed in accidents at abandoned mine sites between 2004 and 2007, and "the potential for more deaths and injuries are ominous," it said.

BLM under fire
The mines are mostly in California, Nevada and Arizona. The California Department of Conservation estimates there are about 47,000 abandoned mines in California. Other surveys have estimated about 500,000 such sites nationwide, where gold, silver, copper, lead and other minerals were mined, often decades ago.

Environmentalists have estimated cleanup costs as high as $72 billion. But the inspector general's audit noted that simple precautions could be taken, such as fences and warning signs. So far, the audit indicates, the Bureau of Land Management has hardly been up to the job.

"BLM's abandoned mines program has long been undermined, neglected and marginalized by poor management practices and insufficient staffing and resources," said the report.

In response, BLM issued a statement defending its abandoned mine program as "highly effective." The statement did not address specific circumstances raised in the audit.

"The BLM has an active program in place to identify and address (abandoned mine land) hazards on its lands," said spokesman Matt Spangler. "The agency worked closely with the IG audit team over the last year in examining the abandoned mine site challenges that it faces. The BLM accepts the IG's recommendations and will work diligently to implement them."

'Quick call to action'
BLM is part of the Interior Department and administers 258 million acres of public land primarily in 12 Western states. The majority of abandoned mine sites within Interior Department jurisdiction are on BLM land.

Last year, 13-year-old Rikki Howard died and her younger sister was injured after they accidentally drove their all-terrain vehicle into an open 125-foot mine shaft near BLM's Windy Point Recreation Area in Kingman, Ariz.

The mine shaft is on a small piece of private property surrounded by BLM land. Only after the accident, BLM provided a fence and warning signs for the site. Yet when auditors visited the area, they found two other deep mine shafts nearby, one unfenced and one only partially fenced, and with no warning signs.
