Usually, his violation penalty will be imposed by the judge who originally sentenced him. He will have to do the violation time at the location determined by the jurisdiction of the original crime. If he has additional county time on top of the violation, that might be run concurrent but if you want to be sure, check with the Clerk of the Court to see how the judge wrote the order (and hope the word "consecutive" is not in there).
