Taiwan’s case provides a good illustration. To control marine
pollution by ships, the Marine Pollution Control Act stipulates
that wastewater, oil, waste and other polluting substances shall
remain on board or be discharged into on-shore reception facil-
ities. An exception is made for legally permitted waste discharge.
However, there are no further conditions specified for legal
discharge and have no cases reported against the regulations,
indicating that the regulations have virtually no deterrent effect.
