(a) IN GENERAL.—The Secretary of Defense shall 
declassify documents related to any known incident in 
which not fewer than 100 members of the Armed Forces 
were exposed to a toxic substance that resulted in at least 
one case of a disability that a member of the medical pro-
fession has determined to be associated with that toxic 
substance. 
(b) LIMITATION.—The declassification required by 
subsection (a) shall be limited to information necessary 
for an individual who was potentially exposed to a toxic 
substance to determine the following: 
(1) Whether that individual was exposed to that 
toxic substance. 
(2) The potential severity of the exposure of 
that individual to that toxic substance. 
(3) Any potential health conditions that may 
have resulted from exposure to that toxic substance.

quired to declassify documents if the Secretary determines

and immediately threaten the security of the United 
States.
