Narrative:

On vectors to ILS final for runway 21 leveling off at 7;000; got an egpws 'terrain; pull up' oral warning. I executed the escape procedure which caused an altitude deviation of about 200 ft and the single oral warning terminated. ATC was queried to verify proper minimum vector altitude and told about the egpws warning. On the ILS approach plate there is a spot peak of 4;549 ft which we suspect is the location of the event. I suspect that this peak must some how penetrate the egpws terrain arrival parameter (even though the aircraft was +3;000 ft with an initial aim recommended descent and level off. The rest of the approach and landing was normal and without incident.
