New York state is poised to implement new rules that could have a major impact on the global shipping industry. Invasive species sometimes move from place to place in "ballast water" — that's the water ships suck in and discharge to level their loads. Officials in New York want all that ballast water treated to kill any "living pollution" before it reaches their harbors. But the treatment technology is expensive and untested. Because the state serves as a gateway to the Great Lakes and ports in New Jersey, other states and countries are disputing the new rules.
