Umatilla Chemical Agent Disposal Facility weekly project update - July 21, 2011

The last shipment of sulfur-impregnated carbon (SIC) used in the Pollution Abatement System (PAS) Filter System left a permitted storage area on the depot Wednesday bound for a treatment and disposal facility in Utah. The SIC has been in permitted storage since the first change-out after starting the mustard campaign in 2009.

SIC was designed to capture mercury when processing suspected high-mercury ton containers early in
the campaign.

Wednesday’s shipment was the 12th since shipping began on June 8. About 273,000 pounds, or some 560 containers, have been shipped.
