Daddis At AOPA:
The one you are asking about specifically is not a regulation, but an FDC Notam.
FDC NOTAMs are by definition regulatory.
7-1-1. FDC NOTAM CATEGORIES
FDC NOTAMs refer to information that is regulatory in nature that include the following:
That said, the wording of this one ("advised" rather than "required" and "should" rather than "shall") means it isn't an automatic bust if you should happen to fly over one on your way to somewhere else. However, it does give them grounds to violate you if you choose to practice turns around a point or steep spirals over Calvert Cliffs.
I agree with Ronald Levy. The FAA might not bust you for flying over on your way somewhere. Nor will the plant security. Doing low flying maneuvers is another story all together. I used to work Security at a nuclear site and we would take down tail numbers and report them to the FAA, if we had an aircraft flying low doing maneuvers over the facility. I had a friend whom worked at a nuclear power plant with armed guards and he told me that if the plane in question was within weapons range they would call and get clearance to fire on the plane. Please do not do turns about a point with a power plant dome as the point of reference.
