A little history about VBA's deceptions and cruelty in treating Agent Orange claims:
We started discussions with VA about C-123 Agent Orange exposure in 2010 and met brick-wall resistance. In 2012 we were told during an in-person conference with Mr. Tom Murphy (Director of VBA Benefits Administration) and his staff that VA had already concluded no C-123 crew or maintainer exposure was possible.
Adding a kicker that this, he told me directly that regardless of what medical, scientific or military evidence we might present then or in the future, absolutely no C-123 claims for Agent Orange exposure would ever be approved.
For claims that were denied and then appealed to the Board of Veterans Appeals, here is the boilerplate denial verbiage they came up with:
VA's Office of Public Health is noted to have thoroughly reviewed all available scientific information regarding the exposure potential to residual amounts of herbicides on the C-123 aircraft surfaces. It was concluded that the potential exposure for the post-Vietnam crews that flew or maintained the aircraft was extremely low and therefore it was concluded that the risk of long-term health effects was minimal.
Naturally, I inquired as to exactly what was meant by their "thoroughly reviewed all available scientific information". VA's answer was they'd simply reached a staff consensus in the VHA Post-Deployment Public Health office that no exposure threat existed. And if there was any exposure, it wasn't significant "enough" to cause any adverse health effects. In other words, there was NO such thorough review of relevant literature and only a knee-jerk decision to deny claims.
And boy, did they ever deny claims! Every single one of them.*
I'll point out here that prior to meeting with Murphy, VA had been provided input from numerous scientific and medical authorities as to our exposures. Columbia University, Yale, University of Texas, Oregon Health Sciences University and others had specifically concluded that C-123 vets had been exposed to Agent Orange. I'll remind readers that VA is required to give every benefit of the doubt to veterans' claims, to review claims sympathetically and in a pro-veteran manner yet"required" didn't seem to apply to C-123 claims.
Other federal authorities had also chimed in to support us against VA: the CDC Agency for Toxic Substances and Disease Registry had reported to VA that C-123 veterans experienced 180 times the published military exposure threshold for Agent Orange. Further, that we have a 200-fold greater risk of cancers developing. Eventually, even the Army's Joint Services Records Research Center tried to tell VA we met exposure requirements, but VA's Mr. Jim Sampsel refused to recognize such input. Note here that VA's own regulations specified that Joint Services Records Research Center input was authoritative as regards Agent Orange exposure claims. Nonetheless, Sampsel disputed everything. (Later, Sampsel even told VA's Disability Compensation Committee that Agent Orange was merely hype and hysteria.)
It seems VA was very selective as to what "available scientific information" they were willing to consider, and that nothing affirming the veterans' exposure would be acceptable to them. And nothing ever was acceptable, at least until the Institute of Medicine virtually jammed it down their throats in January 2015.
* Here was a special VA deception. Every single C-123 claim was denied until June 2015, yet Sampsel and Murphy insisted there was no "blanket denial" policy. Clearly, their only policy was that none would ever be approved regardless of what the policy might be named. They disingenuously insisted that each claim was carefully evaluated on its merits, while quietly pretending that C-123 claims were without any merit regardless of medical and scientific evidence.
