... KNOWN CHARACTERISTICS OF Unlike the agent, mercury is not destroyed in the LIC, MUSTARD AGENT STOCKPILES MPF, or DFS or their associated PAS units but persists in one form or another throughout these processes. The HD/HT stockpiles contain bulk storage ton CMA has concluded that using sulfur-impregnated containers and munitions; all of the HD ton containers activated carbon in the PFS during HD/HT processing have been found to contain some mercury, although is an effective method of controlling mercury emissions the amount varies.

No agent is expected to be found on the PFS carbons because in normal operation, the two-stage design of Personal communication between Gary McCloskey, TOCDF the LIC, MPF, and DFS provides a more than sufficient time-temperature history for the constituent elements General Manager, URS Corporation, EG&G Division, and Robert Beaudet, committee chair, March 4, 2009. of mustard agent -- hydrogen, carbon, sulfur, and Information gathered from committee site visit to TOCDF, chlorine -- to be fully converted to common gaseous September 4, 2008.

... PFS carbon beds at the disposal facilities are situated down- Recommendation 6-1b.  In the unlikely event that an stream of the PAS units for the LIC, MPF, and DFS operational upset were to cause both mercury and agent and will not be exposed to any agent under normal to be deposited on the sulfur-impregnated carbon of operation. Furthermore, because the PFS carbon beds the pollution abatement system filtration system, the are situated downstream of the wet scrubbing processes permit might not allow shipping the carbon off-site for in the PAS, trace concentrations of water-soluble com- disposal, even if sufficient time had elapsed for agent pounds are found in the gas phase; however, no water- on the carbon to degrade.
