Depot permit change sought

HERMISTON — The incineration process may be extended by more than five years if a change in a hazardous waste storage and treatment permit at the Chemical Weapons Depot is not approved, say officials with the county and state Department of Environmental Quality.

The proposed modification to the permit, requested by the U.S. Army, seeks to change the point in the incineration process where air pollutant levels are measured. In testing done recently at the depot, employees found the facility can’t both meet the current requirements of the permit and finish its destruction of chemical warfare agents on time.

“We’re no longer working with designs on paper,” explained Sue Oliver, spokesperson for the DEQ, which is monitoring the incineration of the depot’s munitions. “We’re working with a real-world furnace doing real-world things.”

The problem is with the placement of the emissions test in the pollution abatement system, which cools the exhaust gases from the four incinerators, removes particles and neutralizes the gases released when the agents are destroyed.

The original permit guiding the process, issued in 1997, says emission levels have to meet a certain level at a certain compliance point. But each pollution abatement system has five main components, and the compliance point is at the fourth stage — instead of the fifth and final stage, Oliver said.

When the original permit was constructed, it was thought that the final stage of the incineration process wouldn’t be on at all times, she explained. However, because of updated procedures, that last stop is now a requirement, she said.

The last stop, the carbon filters, significantly reduces the amount of total emissions, Oliver said. Because the filters are on all the time, the emissions levels entering the atmosphere should always be in compliance with the permit. But because the testing point for the emissions level is before the carbon filters, the testing will show that emission levels don’t meet requirements.

That would result in a slowdown in the disposal of the weapons. Instead of destroying 30 to 40 rockets per hour, the depot would only be allowed to dispose of a handful per day.

“It will cost the government millions more and won’t improve public safety one iota,” said Umatilla County Commissioner Dennis Doherty, who is an avid supporter of the modification request.

Right now, the plan is to destroy the rockets within 20 months after incineration begins. If the permit modification is denied, the process would take four times longer — about 84 months.

Doherty said it’ll cost the public $72 million a year to dispose of the weapons. Increasing the time period would increase those costs.

But Karen Jones, founder of GASP, a group of local residents who support safe disposal of the chemical weapons and are opposed to incineration, said she’s not convinced the change in the permit is a good thing.

“During the permit process we were repeatedly told that the facility would be able to meet all emissions standards prior to that second bank of carbon filters,” she said. “Those filters were only supposed to be used as a safety check, like a gas mask on the system. (The proposed change) is one more instance when the technology has failed and they’re trying to get around the commitment that they made.”
