1.  Hard rock mines occurring in sulfide ore bodies to post reclamation bonds equal to 1 1/2 times the cost to the State of Montana should it have to reclaim and deal with pollution if mining companies walk away, shirking their reclamation obligations (as they often do). Currently, the required bond must only cover an estimated actual cost, which is negotiated between the company and agency regulators. In most cases the bonds are woefully inadequate, resulting in taxpayers paying for reclamation and water treatment. -sometimes in perpetuity. Mines tapping sulfide ore bodies are problematic because they often produce acid mine drainage, which once created is practically impossible to halt and must be dealt with forever. The Black Butte Mine proposed for Sheep Creek drainage in the Smith River watershed will be tapping copper from an ore body high in sulfides. 
2. The bill also requires all licensed mines to be subject to an independent environmental audit every three years to assess whether operations comply with permits, are causing problems, and have adequate reclamation bonds given changing conditions. Currently no audit requirement exists, and the mining company in partnership with a beleaguered regulatory agency, the Montana Department of Environmental Quality, does monitoring in a perfunctory, catch-as-catch-can basis. This system is not working. 

Tell Legislators that HB 593 is a modest and very necessary measure that helps protect Montana taxpayers from paying for cleanup costs of hard rock mines. It also better ensures that modern mining in Montana is properly regulated to prevent undue environmental damage.
