You are correct. It was in a BANA press release from April 2014. I'll quote and then add the link below it.
Approved a recommendation from the Tactile Graphics Technical Committee that any braille volume containing one or more tactile graphics should contain a note on the Transcriber's Notes page stating: "The Guidelines and Standards for Tactile Graphics, 2010 was used in the preparation of the tactile graphics."
Hope this helps ...
