The limits apply to within 100 miles of Otis Air Force Base (Cape Cod, MA)
which has a PAVE PAWS radar operating around 70cm.
Apparently exceptions are sometimes granted. At least one group operated a
VHF contest with power from Martha's Vineyard or Nantucket with permission.
There has been info in QST on this. 70 cm repeaters were causing
interference with the radar and there was an extensive negotiation between
the military and ARRL to bring the repeaters into compliance without
shutting them down totally.

The situation affects 15 repeaters within less than 100 miles of Otis
Air Force Base on Cape Cod, Massachusetts, and more than 100 repeaters
within some 140 miles of Beale Air Force Base near Sacramento,
California.
K6EL>>>the limits include a lot more than 100 miles around Otis. Here is a
link to the map showing where the restrictions apply. The area around Otis
is a pretty small percentage of the total. As noted, there were more than
100 repeaters affected in Northern California. A recent report locally is
that virtually all of the interference within the ham band is now gone.
Here is the map...
