Without knowing all the intricate details of plan language, investments, procedures, etc., etc...
In general terms, based on what you've said, I would allow the distributions. VCP approval could take a long time, and it isn't fair to these participants to suffer for an employer error. If you assume the IRS approves, and again, based on what you've said, I assume they will, then you are good anyway. If they don't approve, either you will have overpaid them what I assume will be an insignificant amount, or if the IRS says you have to deposit more for some reason, then you make an additional payment.
