The U.S. Coast Guard is working to develop a new standard for cargo ships to
help stop the spread of aquatic invasive species. Officials are holding five
public meetings to discuss the environmental impact of such a standard. The
Great Lakes Radio Consortium’s Mark Brush reports:
At the moment, foreign ships coming into the Great Lakes are supposed to exchange
their ballast water in the open ocean to flush out foreign organisms, such as
zebra mussels. But no one knows how effective that is. Now, the Coast Guard
is developing a standard that will establish how biologically clean a ship’s
ballast water has to be.
Mike Gardiner is a commander with the U.S. Coast Guard in Cleveland:
“I think that some of the preliminary work would indicate that if you eliminate
organisms above a certain cutoff, and you take care of everything that size and
above then you tremendously reduce the chance that you’re going to have an
invasion.”
The Coast Guard is holding a series of public meetings across the country in the
next month in including one in the Great Lakes region. They hope to get input
from biologists, the shipping industry, and environmentalists to help develop
the national standard.
