Last of chemical weapons slated to be destroyed in Tooele
Deseret Chemical Depot officials today are marking the end of the destruction of thousands of tons of aging chemical weapons stored here, by processing the final mustard agent-filled 155 mm projectiles at the depot’s incinerator.
The observance of the end of the mustard agent’s stockpile is set for 2 p.m. and includes a media event in which Col. Mark B. Pomeroy, depot commander, will speak, as well as Ted Ryba, site project manager.
Workers are then slated to begin processing the last remaining chemical agent, Lewisite, through the depot’s Area 10 Liquid Incinerator.
When the last of the Lewisite is processed on Saturday, it will mark the end of a 16-year, $3 billion mission in the remote western desert of Utah.
It will mean seven of nine U.S. sites of stockpiles of chemical weapons are destroyed, with only 10 percent remaining of what the country declared — 31,500 tons — back in 1985.
Tooele was the first continental site in the United States to go operational in August 1996.
