The plant shutting down due to internal leakage is an engineering success. At no time has a chemical agent leaked out of the plant into the environment, as the internal filtration system bars any plant air going into the outside atmosphere without scrubbing. Regardless of how the weapons are destroyed, there will be an environmental hazard until the destruction is complete. Again, I would have no qualms about this plant being next door. The systems and safeguards in place make the possibility of an external leak miniscule. We are not the Soviet Union, with thousands of square miles of territory uninhabitable due to environmental catastrophes. The US military is switching to non-lead ammunition to avoid environmental difficulties, all our vehicles have spill kits, and all our personnel are trained in the cleanup of spills. We are possibly the "greenest" military in the world. I sincerely doubt a project planned and executed by the current DOD would be allowed to go forward without extensive vetting by all agencies involved.
