U.S. Sen. Ron Wyden (D-Ore) has joined Colorado's two senators — Republican Wayne Allard and Democrat Ken Salazar—in introducing legislation to ban a feasibility study the Department of Defense needs to clear the way toward transporting chemical weapon materials across state lines, possibly to Oregon, to be destroyed.

"One possible incinerator site for transported chemical weapons materials is the Umatilla Chemical Depot in eastern Oregon; any materials transported to the Depot would travel 
throughout eastern Oregon and along the Oregon-Idaho border on their journey," Wyden said.

“Protecting Oregonians near the Depot and along any potential transport route for some of the 
world’s most dangerous weapons is a priority, and this bill should stop the Pentagon’s latest move in its tracks,” said Wyden. “The Defense Department has already studied to death the risks of shipping chemical weapons across state borders, and it’s time to take that possibility off the 
table once and for all.” 

Wyden said that the Pentagon on January 19 reported it would conduct a three-month study on the feasibility of transporting the stockpiles out of Colorado, Kentucky and Indiana to operational sites in Oregon and other states, at a cost of nearly $150,000, "despite the fact that the Department of Defense has conducted three similar studies over the last two decades, all of which concluded such a plan would be impractical. Currently, it is against the law to transport chemical munitions across state lines."
