EOD at Cat can only touch it is it is on their patch. If it is on someone elses patch EOD need a tasking. The only way to get an EOD tasking, properly, is to contact the appropriate EOD Ops. The easy way to do that is to tell the civ pol. They have a procedure and the whole exercise is painless.
As far as keeping it it concerned I would guess EOD may claim it as a trophy.
