RIDDLE, Ore. (AP) — U.S. Rep. Peter DeFazio on Thursday toured an abandoned copper mine in southwestern Oregon that is on the Superfund list of major pollution sites as he prepares to file legislation to overhaul the nation’s primary mining law.

DeFazio, D-Ore., said the Formosa Mine, which is on federal and private land outside Riddle, illustrates what is wrong about the 1872 Mining Act: The Canadian companies that reopened the mine in the 1990s have disappeared, the bond put up for cleanup was nowhere near enough to cover the true costs, and the federal government never got a penny in royalties.
