A researcher says the decline of some tiny aquatic animals at
the bottom of the food chain continues in the Great Lakes. The
GLRC’s Chuck Quirmbach reports:
There’ve already been some signs that organisms vital as food for
Great Lakes fish are dropping in numbers. Now comes the first batch of data collected
for the EPA in all five lakes from 2001 to 2005.
Project Director Mary Balcer of the University of Wisconsin-Superior
highlights one species that seems to be in more trouble:
“One of the more important things is that the diaporeia are disappearing. These are small
shrimp-like animals that live down in the bottom sediment. And scientists had been noting
decline in Lake Michigan and Lake Huron for several years and our data confirms that
the organism are continuing to go down in numbers.”
Balcer says scientists believe zebra mussels might stealing the food
the tiny organisms used to eat.
The Environmental Protection Agency says it will start monitoring the air around some large livestock farms this winter. The EPA says it will help them develop better air quality standards for these farms. But critics say the project is too soft on polluters. The GLRC’s Mark Brush has more:
The Environmental Protection Agency says it will start monitoring the air around some
large livestock farms this winter. The EPA says it will help them develop better air
quality standards for these farms. But critics say the project is too soft on polluters. The
GLRC’s Mark Brush has more:
Thousands of farms have agreed to be a part of a voluntary air pollution monitoring
project. Big hog, poultry, and dairy operations produce a lot of manure. The manure
releases gases that can cause health problems. As part of the agreement with the EPA,
the farms will be immune from most federal lawsuits while the monitoring is done.
Jon Scholl is with the EPA. He says this voluntary approach will bring more farms into
compliance faster than direct enforcement:
“We have 2,568 agreements covering 6,267 farms that have a written agreement with the
agency that they’re going to come into compliance with applicable air quality laws, and
we think that’s significant and certainly much better than taking it on a case by case
Critics of the voluntary project say there is enough evidence now to force these large
farms to comply with air quality laws. They say the Bush Administration lacks the
political will to do so.
A chlorine manufacturing plant is discharging mercury at the highest rate of any industrial plant in the nation. A state agency is trying to get the plant to reduce the pollution. The GLRC’s Fred Kight has the story:
A chlorine manufacturing plant is discharging mercury at the highest rate of any
industrial plant in the nation. A state agency is trying to get the plant to reduce the
pollution. The GLRC’s Fred Kight has the story:
The PPG Industries plant has dumped as much as 32 pounds of mercury a year into the
Ohio River. Mercury is a toxic chemical that causes nerve damage in humans. West
Virginia’s Environmental Quality Board found that state regulators had allowed PPG to
dump mercury in amounts many times the legal limit.
Margaret Janes is with the Appalachian Center for the Economy and the Environment.
She praised the decision against the plant:
“They’re using a technology that is from the 1800s. There are other cleaner technologies available.”
The plant reportedly is one of only nine in the country that makes chlorine by pumping
saltwater through vats of pure mercury. PPG Industries says it will appeal the West

Some data on avian flu outbreaks are restricted by governments, or kept private within small

the first to publish in academic journals, according to correspondence published online by
the journal Nature.
Seventy top flu scientists and health officials propose sharing all data through what
they’re calling the Global Initiative on Sharing Avian Influenza Data. The consortium
and its data will be open to all scientists provided they agree to share their own research.
Any articles published in academic journals would have to credit the use of other
researchers’ data. The idea is to more quickly allow scientists and health officials world-
wide to better understand how avian flu viruses spread and evolve before they reach

Researchers at the Oak Ridge National Laboratory in Tennessee say they loaded all kinds
of climate, pollution and population data into one of the lab’s supercomputers. As
expected, they found that demand for heating in the winter will drop as the earth warms,
but not enough to compensate for the higher demand for air conditioning in the summer.
David Erickson led the project. He says that could make the problem of global warming
“You’re going to end up having to create electricity by burning of coal, which feeds back
and adds more CO2 into the atmosphere that causes warming.”
Erickson says the computer models they’ve created can be adjusted to adapt to any
changes in energy technology or policy.
Feral pigs are a big problem in many states, and while many are escapees from farms, some are actually let loose by hunters. The

Feral pigs are a big problem in many states. And while many are escapees
from farms, some are actually let loose by hunters. The GLRC’s Brian Bull
reports on how the problem is playing out in one area:
Feral pigs have appeared in several states including Oregon, California, Indiana, Illinois
and Wisconsin. Recently they started showing up Minnesota. It was first thought wild
swine might’ve crossed frozen waterways from Wisconsin. Wisconsin wildlife biologist
Dave Matheys says the growing problem is more likely due to hunters using pigs for
“Some bear hunters who train their hounds, train them on
pigs, and don’t recapture the pig. It escapes, or the hounds aren’t
trained thoroughly enough or they just don’t want to recover it, so
the pig or pigs remain out in the wild.”
Feral pigs damage the habitat of ground-nesting birds, kill
small deer, and despite their shy nature, have even attacked people.
Matheys says the wild pigs are prolific, and eat almost anything, making them hard to
monitor and control. In some states wildlife managers have declared an open season on

A new assembly plant from one of Detroit’s Big Three car companies is getting attention for its “green” qualities. Big Three automakers may not rank at the top of most environmentalists’ list for companies of the year. But some say the new auto plant is a sign that environmentally-sensitive manufacturing has finally gone main-stream. It’s not just because building green plants is the right thing to do. Really, it comes down to a different kind of green. The GLRC’s Dustin Dwyer has the story:

The first thing you notice about the smell of General Motors’ newest plant is how much
you don’t notice it. The plant smells like nothing at all. Not paint, grease or even that
new car smell. GM says it specifically selected materials for its new Lansing Delta Township
Plant in Michigan to limit indoor air pollution. And there’s a lot more to not notice about the plant.
Like how much space it doesn’t use.
On a tour with reporters, GM Environmental Engineer Bridget Bernal points out that less
than half of the plant’s 1,100-acre lot has been developed. The rest is left green, including
75 acres for habitat preservation:
“And basically in that 75 acres, we have a couple of pretty large wetlands, along with
some smaller wetlands. We have a rather large wood lot. And we’ve got a significant area
that’s being developed as native prairie.”
GM says it only planted native species on the site. And it planned ditches and culverts to
help filter water as it drains into other areas. A quarter of the materials used to build the
facility was recycled. The plant uses 45 percent less total energy than a traditional plant.
And, on the day GM gave reporter tours, it rained. Even that gets used. The water is
collected in cisterns, and used for flushing. GM says the plant saves a total of more than 4
million gallons of water per year.
Put together, all these elements were enough to win GM a LEED Gold Certification from
the U.S. Green Building Council.
Kimberly Hoskin is director of the council’s new construction program. She says she’d
been traveling a lot for work when one of her colleagues asked if she’d be willing to take
a trip to an event Lansing, Michigan.
“And I said, ‘Well, who’s it for? And she said, well, General Motors.’ General Motors, a
factory, is getting a LEED Gold Certification? Yes, I’ll go. Of course I’ll go. This is really
GM is not the first auto company to use green elements in an auto plant design. Ford’s
Rouge Plant in Dearborn, Michigan was built earlier this decade with a 10-acre “living”
roof that helped manage storm water runoff.
But Hoskin says, out of about 560 buildings in the nation that have been certified by the
Green Building Council, only five are manufacturing facilities, and GM says the Lansing
facility is the first auto assembly plant to get Gold, the agency’s top rating.
But for GM, the green elements of the Lansing Delta Assembly Plant aren’t just about the
environment. They’re about cold, hard cash. The lower energy use alone will save GM a
million dollars a year. That gives people like Hoskin comfort that the plant isn’t just a
public relations move by GM and it increases the chances that we’ll see more green plants
in the future.
Sean McAlinden is Chief Economist with the Center for Automotive Research:
“As we slowly replace our old big 3 plants, many of which are very elderly, they’re all
going to look like this. They’re all going to be green plants. In fact, some of them will
keep getting greener.”
That’s good news for places where there’s a lot of auto manufacturing, but many people
are not ready to absolve GM of all of its environmental sins.
David Friedman is with the Union of Concerned Scientists. He says a green plant is nice,
but the real problem is still the product:
“Over eight times the impact on the environment when it comes to global warming is
once that vehicle leaves that plant. That’s the biggest step that we need automakers to
take and to improve the fuel economy of all of their cars and trucks.”
GM, and other automakers, say they are working to make cars cleaner. High gas prices
may force even more changes as sales of big pickups and SUVs drop off. Ultimately, car
makers’ profits could depend on building cleaner cars, just as keeping manufacturing
costs down will depend on having cleaner plants.
That could change the way auto companies think about environmental improvements
because going green will be about more than just doing the right thing, or protecting the
brand image. It will be about protecting the bottom line. What’s sustainable for the
environment will also be sustainable for the business, and both will show a lot more

Many people are drawn to live near rivers, lakes and other bodies of water. That means they have to take special care in case of floods, but flood walls and levees don’t always protect them. In one town, residents are asking why the wall separating their backyards from the neighboring river didn’t hold back the water.

the safety of floodwalls and building in a floodplain:
Dale and Donna Smrdel bought a condominium along a river just a few months ago.
This summer they’ve been sitting in the backyard on a wall overlooking the river and
watching the sunset. But now, that concrete wall is broken and falling away from the
bank. It’s crumbled in some spots and held together only by twisted rebar.
“This is where the largest portion simply fell away because of the water. It was a torrent.
It was so strong it picked up a camper and flung it over this wall. Because the water was
so high above the wall, that it was like a toy. It just floated away like a toy.”
People on rafts rescued everyone from
second floor windows. Donna Smrdel says they thought this wall would protect them
“I don’t think there was a single person here that believed this was not going to keep us
safe. I think we all believed that even if the water did rise that it wouldn’t hurt the
retaining wall. None of us are engineers. We looked at it, it looked safe. We believed
we were safe. We had no idea, we just had no idea.”
This story is not uncommon. Last year, people in New Orleans expected a flood wall to
protect them from rising waters brought on by Hurricane Katrina. People along the
Mississippi River expected levees and flood walls to protect them from the Great Flood
of ’93. Many flood walls hold, but when they don’t, the people who thought they were
protected quickly find out they’re victims. In the case of the Smrdels, it turns out that
wall wasn’t even meant to protect them from high water.
Painesville City Manager Rita McMahon says the Smrdels live near the exit of the river,
where ice often jams in spring:
“Well, that wall was built by the private property owner as actually a flood protection
from ice dams. It wasn’t intended to protect the property from this type of a flood. This
was a volume flood that came from the south to the north. It was just a wall of water, so
The Smrdel’s condo community was built in the 100-year floodplain 30 years ago. Back
then, there weren’t regulations on building in a flood-prone area. Today, new buildings
have to be elevated.
That’s better protection then a wall, but flood walls and levee protection give people a
sense of security. Often they don’t think about that protection failing them, and the
consequences of what that failure will mean to their homes and families. Engineers say it
is possible to live safely by the water, but homeowners have to do their own investigating
to find out the safety of housing elevations and flood walls. We spoke with Carm
Marranka, a structural engineer with the US Army Corps of Engineers:
Julie: “When you look at Katrina, when you look at the Mississippi floods in ’93, and when we
look up here, do you think that sometimes flood walls, even those built by the Army Corps,
provide a false sense of security?”
Marranka: “I don’t know if it’s a false sense of security. I think
with the design and assumptions that I’m familiar with the factors of safety, those
structures are built at. And good maintenance, I think that’s a big issue. They have to be
maintained. They cannot be allowed to fall into disrepair.”
When the Army Corps builds a flood wall, Marranka says it’s usually up to the local
community to maintain it, but the local governments often don’t have enough money to
pay for that maintenance. Donna Smrdel doesn’t trust any of it anymore:
“I mean, even if they bulldozed it, what kind of retaining wall will they build next? If
this didn’t work, and we all believed it would work, what do you build next?”
All those other people flooded out of their homes will also have to decide whether they
trust flood prevention technology, and if living by the beautiful scenery is worth the
threat of floods.

Patterson would prefer the government set up vehicle barriers along the border. He says
they would allow wildlife, and admittedly people on foot to cross, but would prevent
smugglers from driving people into the US. So far, the US House and Senate have been
unable to agree on immigration reform measures, including the wall, and it’s possible
they won’t before the end of the year.

pumped into deep-sea sediment. The GLRC’s Christina Shockley reports:
Right now, carbon dioxide is usually just released into the atmosphere. One solution
could be pumping it into the ground, but it might leak back out.
Dan Schrag is a professor of Earth and Planetary Sciences at Harvard University. He co-
authored a study that shows carbon dioxide pumped into sediment in the sea floor
wouldn’t come back up:
“It’s a very high pressure because of the weight of the overlying water, but very low
temperature. And as a result, the carbon dioxide sits not as a gas, but as a dense liquid.
It’s in fact denser than the sea water and so it wants to sink, not rise.”
Schrag says the carbon dioxide would be stable under the water for millions of years. He
says this is one option of many that need to be considered.
Schrag says the technology exists to get the gas underground, but cost could be a major
