Environmentalists decry EPA lakes
United Press International
DETROIT -- Environmentalists charge the U.S. Environmental
Protection Agency is hurting efforts to combat exotic,
invasive marine species in the Great Lakes.
The EPA ruled ships do not need permits to discharge
their ballast waters and that could mean more foreign
species in state waters, Lake St. Clair environmentalist
Doug Martz told the Detroit News.
Scores of exotic species of marine life, from plants
and plankton to zebra mussels, have been introduced into
the Great Lakes during the last couple of decades from
the ballast water of passing foreign ships, the News said
The zebra mussel, which clog water intake valves and
wipe out native marine species, have cost the Michigan
economy $1 billion over the last decade, the News said.
The EPA said last week it could not control ballast water
discharge in the Great Lakes because there are too many
commercial cargo and fishing ships to police.
