States must act on ballasts

Posted January 9, 2006
We understand the concerns of Great Lakes shippers worried
that a hodgepodge of state laws governing overseas freighters
and their discharge of ballast waters could hurt the struggling
industry. A federal law would indeed be a better solution.
But since it doesn't appear that Congress will pass such
a law anytime soon, we see no reasonable alternative to
states acting on their own.
Because given the dangers that are known to swim in those
ballast tanks, doing nothing to tighten the rules governing
their discharge is certainly not reasonable. The danger
comes from the invasive species, such as zebra and a couple
of other mussels, that scientists argue have used the
ballast tanks of overseas freighters to infiltrate the
Great Lakes. Of the estimated 60 non-native species that
have been found in the lakes since 1970, about 70% have
invaded via those tanks, scientists say. And the mussels
alone have caused local governments to spend about $1.5
billion over the last two decades just to keep pipes clear.
Invasive species are indeed a national and even international
problem, but in the absence of national and international
action, states can no longer afford to sit back and let
the invasions go unchecked. Michigan has already approved
a law that will, beginning in 2007, impose tough fines
for discharging contaminated ballast. To their credit,
state Senators Robert Cowles (R-Green Bay) and Neal Kedzie
(R-Elkhorn) and Rep. Scott Gunderson (R-Waterford) are
working on similar legislation for Wisconsin. Gov. Jim
Doyle says he will support such a proposal.
Port directors and shop operators are worried that a
patchwork of costly and confusing state laws could make
it difficult for them to operate. Certainly, every effort
should be made by state legislatures in the Great Lakes
states and Canadian provinces to come up with rules that
are consistent with each other. The aim is to reduce the
number of invasions, not sink an industry.
Of course, it would be better if members of Congress
enacted a federal bill aimed at curbing the invasions.
And one has to wonder why the representatives and senators
from the Great Lakes states - including those from Wisconsin
- haven't pushed harder for federal legislation. But here's
where state action might help.
As Cowles put it: "This is pressuring federal lawmakers.
If enough states do something, then (they) have to take
notice." Here's hoping he's right.
