Conservation groups on Tuesday ripped a federal proposal to further shield the Great Lakes from the invasion of non-native species, such as zebra mussels and Asian carp.
The groups said the Environmental Protection Agency's
draft vessel general permit to regulate ballast water discharges from
commercial ships is far too weak and falls short of the agency's
obligation under the Clean Water Act.
"The
EPA's new proposed permit isn't tough enough to prevent the next
harmful invader from slipping into our waters," Thom Cmar, an attorney
with the Natural Resources Defense Council, told reporters.
Cmar said EPA was failing to take advantage of Clean Water Act tools "to finally slam the door on invasive species stowing away in vessels' ballast tanks."
The Natural Resources Defense Council joined Alliance for the Great Lakes, Great Lakes United, National Wildlife Federation
and Northwest Environmental Advocates in a 34-page critique of the
updated vessel general permit EPA proposed at the end of last November.
Tuesday capped a 75-day public comment period.
EPA's
new ballast discharge permit would require ships to install technology
strong enough to eradicate much of the invasive species that prowl the
water taken on for balance before it is dumped into harbors. Ships also
would be required to empty ballast water before entering the Great
Lakes.
More than 180 species, including zebra
and quagga mussels, spiny water fleas and round gobies, have invaded the
Great Lakes, damaging the ecosystem and costing the region about $200
million a year in damage and control costs, according to one study.
About two-thirds of the nuisance species are believed to have entered
through ballast water.
Critics of the proposal say it doesn't go far enough to ensure no non-native species are able to infiltrate the Great Lakes.
"Half-measures will not cut it," said Marc Smith,
senior policy manager for the National Wildlife Federation's Great
Lakes office. "Prevention is the only responsible course of action to
stop the influx of living, breathing, biological pollution into U.S. waters."
