U.S. Rep. Peter DeFazio, D-Ore., looks over the closed entrance to the Formosa Mine outside Riddle, Ore., on Thursday, April 17, 2014. DeFazio toured the site to raise awareness of the failings of federal mining regulations to require mine operators to put up bonds sufficient to cover cleanup costs. The $900,000 bond put up by the Canadian owners before walking away is a fraction of the more than $20 million in estimated cleanup costs, which will be picked up by taxpayers. (AP Photo/Jeff Barnard)
