Oregon environmental managers have agreed to re-open public debate on the best way to get rid of equipment used to break down chemical weapons.  That follows a lawsuit by government watchdogs.

They say Oregon isn’t doing enough to protect them from pollution generated at the Umatilla Chemical Depot outside Hermiston. Correspondent Anna King reports.

The group is especially worried about mercury and other chemical emissions that could be released during the incineration of mustard gas, plastic suits and carbon filters. The group wants the Army to neutralize the chemical agents like mustard gas and VX nerve agent by using chemical solutions instead.

But Richard Duval with Oregon’s Department of Environmental Quality says there are no tests available to show that neutralization is safer.

Richard Duval: "There are other technologies that can decontaminate secondary waste, but most of those secondary wastes like bulk items like protective gear and carbon, there is no sampling methodology available to make sure they are agent free."

A public meeting will be held later this year and people will also have a chance to write in comments.

Duval says incineration of secondary materials will continue during the public process.
