Wis. power plant will kill billions
of lake fish, Sierra Club claims

Billions of fish in Lake Michigan will die over the next
50 years if a new power plant is built south of Milwaukee,
according to a Sierra Club lawsuit.
Fish eggs, fry and larvae will be killed by a water intake
extending 1-1/2 miles into the lake, the environment group
We Energies, which wants to build a $2.2 billion Elm
Road Generating Station next to its Oak Creek Power Plant,
said the project's design will minimize harm to the environment.
Depending on their size, the fish and much of their food
supply will either be sucked into the plant or trapped
against grates on the end of the intake, the Sierra Club
Also, the group said, the plant will return water to
the lake 15 degrees warmer, killing fish and other aquatic
life at the shoreline.
"Fish and the tiny plants and animals at the base
of the food chain can't swim out of the way," said
the Sierra Club's Bruce Nilles. Billions of fish will
die over the power plant's projected 50-year life, he
How it's done in Illinois
The Elm Road plant's two units would pipe in 2 billion
gallons of lake water a day to cool off coal-fired boilers.
This technology is "completely unnecessary,"
Nilles said. It has been outlawed in Illinois, where cooling
towers are used instead. The tower system requires less
water, recycles most of it and doesn't return it heated
to lakes or rivers. Peabody Energy's plant southeast of
St. Louis draws only 30 million gallons a day from the
But spokesman Thad Nation said We Energies' method actually
conserves water. While towers lose a lot of water to evaporation,
the Elm Road plant will put "99 percent" of
it back into the lake.
And because lots of electricity is needed to power a
tower, the plant would have to be larger and thus cost
more to build and operate. "Electricity is always
about trade-offs," Nation said.
For the intake, experts from the University of Wisconsin
at Milwaukee found a sandy shoal on the lake bottom where
little marine life will be disturbed, he said. Using 20
smaller intakes instead of four large ones will cut the
inflow rate, and covers with a fine mesh will reduce the
amount of aquatic organisms being sucked in.
Illinois Attorney General Lisa Madigan, the Chicago-based
Alliance for the Great Lakes and other environmental groups
also have filed legal challenges to the proposed plant.
"At a time when we're trying to clean up the lake
and restore fisheries and habitat, this power plant is
a major step backward," said Cameron Davis, executive
director of the alliance.
