We are FDIC and I am taking the same approach as you. I have implemented procedures based on the law as best as I can and just explained during training that this will all change when the final regulation is released.
If you have a FCRA policy, I would add the FACTA provisions to it. I am not, at least at this time, doing a separate FACTA policy.
Just my two cents! Not sure if I am right or wrong with this approach.
