- New units added to an existing facility are required to reduce mortality of aquatic organisms that achieves one of two alternatives under national entrainmententrainmentWhen aquatic organisms, including eggs and larvae, are pulled from a water body into an industrial facility cooling system, passed through the heat exchanger, and then discharged back into the source water body. standards.
