FILE - In this Jan. 29, 2015, file photo, ordnance technicians use machines to process inert simulated chemical munitions used for training at the Pueblo Chemical Depot, east of Pueblo, in southern Colorado. The costly plant in Colorado that destroys U.S. chemical weapons without incinerating them is over budget, behind schedule and bedeviled by troubles that could worsen the danger to workers. But when the Army said this month it wants to spend millions more installing older technology to help the beleaguered plant and reduce worker risk, public reaction was more acceptance than anger.
