If you're plugging it in with the switch turned on, it's just induction - electricity bridging the gap between your plug and receptacle. A motor is an inductive load so it will draw a small arc when you plug it in with the switch turned on. You've probably got your disposal problm solved by now but I just joined today and wanted to explain what the sparking probably was.
