The U.S. Army Corps of Engineers, in charge of destroying chemical munitions buried in Spring Valley in Northwest Washington, has not formulated a public safety plan in the event that an accident occurs when the agency destroys the weapons in April, Army Corps officials told a D.C. Council panel Monday.

The Spring Valley area was used as a weapons-testing site during World War I, and toxic chemical munitions are still being discovered there. The Army Corps recently found five munitions at Spring Valley, which they plan to dispose of on federal land. Local residents say the chemicals in the weapons have the potential to become hazardous if exposed to the public.
