I don't doubt that you are right. But we also are not dealing with wetlands here. Also, where is the threshold? People put small ponds in their backyard all the time. Is that just small enough to go unnoticed? Oh well, I've nearly given up on the pond idea as I have gotten some better prices for fill and it is almost certainly going to cost significantly more to dig the pond.
There could be three layers of regulations to determine the threshold: state, county and local municipality. All of those conform to federal rules too, of course. The best way to find out for your location is to do some info digging and talk to your local DEP/Conservation people.
As an example, I could dig a 1/10 acre pond in a wooded wetland without triggering permitting. Exceed that and the paperwork piles on rapidly. Anything within 100' of a stream, pond or wetland needs a permit generally. Some Maine towns require a permit, or forbid ponds outright, if the depth of the excavation will reach the water table since the pond represents a point of potential ground water contamination.
It can be complicated and you want to know before you dig. Since the pond contractor gave you a quote and didn't mention any permit obstacles, I would guess that you don't have much to deal with.
