(4)"Empty/refill exchange" means to pump out, until the tank is empty or as close to empty as the master or operator determines is safe, the ballast water taken on in ports, estuarine, or territorial waters, and then refilling the tank with open sea waters.

(6)"Flow through exchange" means to flush out ballast water by pumping in midocean water at the bottom of the tank and continuously overflowing the tank from the top until three full volumes of water have been changed to minimize the number of original organisms remaining in the tank.
