Chemical weapons incineration resumes at Depot

HERMISTON — The Umatilla Chemical Agent Disposal Facility processed 251 rockets Thursday during it’s first day of operation after a three-week shutdown to investigate a series of rocket fires.

Processing resumed at 1:45 p.m., said Adam Russell of the Washington Group protocol office, following receipt of a letter from the Department of Environmental Quality authorizing the restart. Washington Group operates the disposal facility for the Army.

“Everything went pretty smoothly,” Russell said.

The rocket fires — three over six weeks — involved inadvertent ignition of propellant remaining in the rockets as they were being cut up for incineration, resulting in a low-order explosion and fire. DEQ issued a stop-work order after the last fire May 18. All the fires occurred in the Explosive Containment Room, so no workers were in danger and there was no threat of a chemical agent release.

Russell said engineers did make an additional modification Thursday when it was determined too much water was being sprayed into the deactivation furnace. That issue was expected to be resolved today so rocket processing could continue.

When processing started Thursday, one rocket at a time was moved through the Explosive Containment Room to ensure all systems were working properly, Russell said.

Eventually, two rockets were moved through at one time — one being punched and drained of sarin agent while a drained rocket was cut into pieces — so the operation was operating a full production.

A rocket task force organized by the Army to investigate the rocket fires at the Umatilla Chemical Depot and Pine Bluff Chemical Agent Disposal Facility in Arkansas has been unable so far to definitively determine the cause of the fires.
