Really, no. If I call and ask if such and such a project will require the 45 day comment period, why should I be suprised to hear "if it's only that, it should not, but nonetheless the comment period is only 30 days"?
(a) IF it needs comment, the guy was telling rawnoc he had the wrong period for a comment period.
(b) he never really answered, as without an application, it cannot be answered except in the general.
