New Law for Great Lakes Ships

The Saint Lawrence Seaway is now open to international ship
traffic from the Atlantic Ocean to the Great Lakes. But as
Sarah Hulett reports, the start of this year’s Great Lakes
shipping season is raising questions about a new state law aimed
at protecting the lakes from invasive species:


The state of Michigan is now requiring ocean-going ships that
come into the state’s ports to get ballast water permits, and
agree not to discharge untreated ballast into the lakes.


Ballast water is pumped in and out of a ship to help keep it
level in the water, but ballast water is known to carry small
organisms from foreign waters that can wreak havoc on Great
Lakes’ ecosystems.


So far, only two shipping companies have applied for the
permits. John Jamian heads the Seaway Great Lakes Trade
Association:


“The joke is that the big players that represent over 98% of the
cargo that comes into Michigan ports have not filed for permits.”


Jamian’s organization and others are suing to get the law
overturned. They say it violates the Commerce Clause of the U.S.
Constitution.
