Cash-pinched states and tribes are struggling to protect the public from unsecured pits, shafts, toxic waste piles and other features of abandoned hard rock mines, and Congress needs to step in, according to two groups comprising state and tribal agencies that manage mine reclamation and safety.

The Interstate Mining Compact Commission and the National Association of Abandoned Mine Land Programs say in a first-of-its-kind report that 750,000 of 1.8 million former mining sites pose an “immediate danger” to the public.

Addressing both public safety and environmental hazards will cost more than $60 billion, the group said in the report released late last year.
