A tiny green beetle is killing millions of ash trees. And so far nobody’s
found a way to stop it in its tracks. The GLRC’s Rebecca Williams
reports cities and states are struggling to find money to keep the beetle
from spreading:


Once emerald ash borers chew their way into your ash trees, there’s
pretty much only one thing you can do.


(Sound of chainsaw and tree cracking and falling)


Crews here have been sawing down and chipping up trees six days a
week. In some places, crews are cutting down both dead and live trees.
Dead trees are a safety hazard. Cutting live trees near infested areas can
help contain the beetles.


The emerald ash borer is native to China. Scientists think it got in on
wood packing crates more than ten years ago. The emerald ash borer eats
through the living part of the tree just underneath the bark. The beetles
cut off the tree’s water and food supply… so it starves to death. 15
million ash trees are dead or dying in Michigan. Hundreds of thousands
are dying in Ohio, Indiana and Ontario, and it could spread to other states
soon.


Some cities have been hit really hard. For example, some of the trees in
Ann Arbor, Michigan have been dead for a couple of years. Kay
Sichenader is the city’s forester. She says she’s worried about limbs
breaking off trees, or bark falling off in 80 pound chunks.


“There’s some terrifically bad ones out there. Nothing will make me
happier than when those trees are down, I gotta tell you.”


This isn’t the first time cities have lost big shade trees. Dutch elm
disease almost wiped out American elms in the 1960’s and 70’s. It’s a
little ironic: people planted ash trees to replace the elms because they
thought ash trees were invincible.


That love of ash trees means cities are losing 20 or 30 percent of their
trees, and they’re spending millions of dollars to take trees out.


Forester Kay Sichenader says her city normally takes out a thousand old
trees a year. Now, she’s got ten times as many trees to cut down.


“If I never bumped it up, and we just remained with our thousand a year,
we would never change because it would take me ten years to get the ash
out. In the meantime I’d have 10,000 more dead trees to deal with. It’s
sobering.”


Sichenader says the city’s trying to get the dead ash trees out as fast as
they can. She’s contracted five extra crews to saw down trees. She
hopes they’ll be done by the end of the year, but it might be longer.


Many homeowners are getting impatient. They’re worried about big
branches falling on their cars or homes. Or worse, falling on their kids.


Laura Lee Hayes lives in a cul-de-sac with four infested ash trees. She
points out a big branch on her neighbor’s dead tree.


“This whole piece is just laying here, ready to pull off, and there are
small children that play in this yard. That’s why I look to my city to get
over here and get these trees down. There’s a real frightening aspect to
that.”


Hayes says she tried to pay to take the trees down herself, but she found
out it would’ve cost more than a thousand dollars.


In Indiana, homeowners now have to spend their own money to get rid of
dead trees in their yards. State officials say they can’t afford to keep
cutting down live ash trees to slow the infestation. The state won’t be
giving money to help cities cut down dead trees either. That could mean
the emerald ash borer will spread unchecked.


At first, the federal government sent states several million dollars to fight
the beetle, but now the money’s just trickling in. In 2004, Michigan
Governor Jennifer Granholm asked President Bush to declare the state a
federal disaster area. That request was denied. Recently, officials in
Ohio and Michigan said they’ll have to cut back on containing new
infestations.


These trends worry scientists.


Deb McCullough is a forest entomologist at Michigan State University.
She says states barely have enough money to monitor how far the beetle’s
spreading, and she says a lot more money’s needed for ad campaigns to
tell people to stop moving firewood. The beetle spreads fastest when
campers or hunters move infested wood.


“You have to look down the road, and either you spend millions of
dollars today to try to contain emerald ash borer or we’re going to be
looking at losses in the tens of billions of dollars in the future, and it’s not
too distant of a future.”


McCullough says if more funding doesn’t come in states might need to
have timber sales to take ash out before the beetle kills it. And cities will
still be paying millions of dollars to take out dead trees. That means
people who live in those cities might see cuts in other programs or have
to pay higher taxes.


Deb McCullough says the economic impacts are serious… but the
environmental impacts could be even worse. She says it’s hard to know
how wildlife might be affected if we continue to lose millions of ash
trees.

Making Power Out of Pollution

Pollution from factories and other places might be dollars just going up in smoke. But a promising new technology turns these ordinarily troublesome waste products into something that’s especially valuable these days: cheap electricity. The Great Lakes Radio Consortium’s Julie Halpert has this
report:

Pollution from factories and other places might be dollars just going up
in smoke, but a promising new technology turns these ordinarily
troublesome waste products into something that’s especially valuable
these days: cheap electricity. The Great Lakes Radio Consortium’s Julie
Halpert has this report:


Remember the children’s story, where Rumpelstiltskin was able to take
straw, a cheap, abundant material, and magically transform it into
precious gold? Well, these days, cheap energy is like gold, and one
company has found a way to similarly generate power from pollution.


(Sound of engine running)


To see how it works, I’m standing on a roof sixty-five feet above the
ground. This is where Ford Motor Company maintains its pollution
control equipment. There are rectangular gray metal boxes as tall as I am
all over the roof, so many that we can barely walk between them. Under
the roof, they’re painting trucks. The paint emits vapors that Ford is now
capturing with these big boxes of machinery.


Mark Wherrett is Ford’s principal environmental engineer.


“We’re here at the Ford Motor Company Michigan truck plant, where the
paint solvent is collected from the process and used as a fuel to make
electricity in a Stirling Engine.”


The Stirling Engine is key. Here’s how it works. Ford’s using an engine
developed by STM Power. STM is using an old engine style called a
Stirling Engine that was once used in place of a steam engine. Instead of
using coal or wood to heat up water and make steam, STM burns the
paint fumes to heat up hydrogen and power the engine. The fumes will
generate 55 kilowatts of electricity. That’s enough to power 11 homes.


There’s not as much pollution emitted at the end, since burning can be
adjusted to temperatures where pollutants are reduced. Wherrett says
that for Ford, the technology simply has no downsides.


“The fumes to fuel process takes the environmental emissions and turns
them on their head, so instead of them being a waste product that we
have to dispose of, we can then turn it into a commodity where we can
then use that to make electricity and use that in our plant systems.”


And that means Ford doesn’t have to purchase as much power from the
grid.


Dorrance Noonan is CEO of STM Power, the company that’s redesigned
the old engine. Noonan says Ford is a perfect candidate for this
technology.


“We’re really excited about the Ford project because it offers a
tremendous opportunity to manufacturing companies and large paint
operations, who have large VOC problems that they have to deal with in
very expensive ways.”


The Ford plant is just the beginning for the company. They also plan to
deliver their portable on-site generators to landfills and wastewater
treatment plants. In that situation, methane gas is used as the fuel to
generate electricity. Noonan says his company has a bright future.


“Well, in the next couple of years, we see strong penetration in our two focus
markets, which are the landfill markets in the U.S. and the wastewater
treatment markets in the United States, and then we see that expansion
going outside of the United States to Europe and eventually to Asia.”


There are some skeptics.


Dan Rassler, with the Electric Power Research Institute, says STM’s
technology does have the potential to create viable new sources of
energy, but more companies need to actually start using it before he can
know for sure, and he says that right now the technology is still too
expensive for many companies.


“We’d like to see the capitol costs of these systems be lower than where
they are today.”


Right now, an STM unit costs $65,000. Rassler would like to see overall
costs cut by 10 to 20 percent. He says costs could decrease as more of
these units come on line.


STM CEO Dorrance Noonan says the costs are comparable to competing
on-site generators, and these expenses will be offset by using the free
fuel used to generate electricity that his engines provide. Noonan says
that continuing high natural gas prices will be his technology’s best
friend, as companies strive for ways to reduce energy costs.

Making Solar Power Mainstream

Solar panel technology has been around for decades…but not many
people have panels on their roofs. Solar energy is the ultimate clean
power source, but it’s also expensive and that’s kept most people away.
But regulators in one state are hoping to change that. The state’s Public
Utilities Commission recently approved a 3-billion dollar fund to give
homeowners and businesses hefty rebates if they install solar panels. It’s
the first program of its kind and size in the nation. The Great Lakes
Radio Consortium’s Tamara Keith reports:


A little over a year ago, Chuck Wingo and his wife Pam moved into a
new house in an innovative housing development. Their house, like all
the others in the neighborhood, is equipped with bank solar panels, built
right into the roof like shingles.


“These are the 2 meters that are on the house. It’s simple. One uses for
our usage, what we use, and the other one is from the solar panels, what we
produce.”


Chuck says sometimes he walks to the side of his California house and
just watches the solar meter spin.


“We check it all the time, what’s even better is checking the bills. The
bills are great, we paid 16-dollars for our usage in August, the hottest
month in Sacramento. So, it’s kind of cool.”


The Wingo’s weren’t big environmentalists before moving into this
house, but Pam says when she heard about this development, something
clicked.


“The idea just sounded, if you’re going to move, do it right at least. Do
something pro-active about where you’re going to be living and spending
your money. It’s really good for everybody, for the country. We all
should be living like this so we’re not wasting out energy.”


And many more Californians will be living that way, if the California
Solar Initiative lives up to its promise. State energy regulators approved
the initiative, which will add a small fee to utility bills in order to create a
3-billion dollar fund. That fund is designed to make solar panels more
affordable.


It starts by offering rebates to consumers who buy them. Bernadette Del
Chiaro – a clean energy advocate with Environment California – says
once those panels get cheaper, the marketplace goes to work…


“The problem with solar power today is its cost. Most of us can’t afford
an extra 20-thousand dollars to equip our home with solar panels, and
what we’re doing in California is saying, we’re going to get the cost of
solar power down. By growing the market 30 fold in the next 10 years,
we’re going to be able to cut the cost of solar panels in half.”


Last year, Governor Arnold Schwarzenegger tried to get the California
legislature to approve something similar. That plan got bogged down in
state politics … so he took it to the Public Utilities Commission. While
the commission can raise the money, there are some parts of this
revamped solar program that have to be legislated.


Democratic State Senator Kevin Murray has worked with the Republican
Governor on solar power issues. He says he plans to introduce a new bill
that would require solar panels be included as an option on all new
homes built in the state.


“Rather than some specialized left-wing alternative kind of thing, we want it to
be in the mainstream, so that when you go in to buy a new home, you
pick your tile and you pick your carpet and you pick your solar system.
So, that would have to be done legislatively and the other thing that would
have to be done legislatively is raise the net metering cap so that if you’re
selling energy back to the grid, you can get compensated for it.”


The new program would also target businesses, even farms. Public
Utilities Commissioner Dian Grueneich says she hopes this doesn’t stop
with California.


“I’m very, very excited. This is the largest program in the country
and I’m hoping that other states will look at this program as well, so that
it’s not just something in California but helping other states.”


And if the solar power initiative is a success in California, backers say
it’s good news for consumers all over the country. Much like the hybrid
car, made cool by Hollywood celebrities… California leaders hope they
can make solar trendy and more affordable for everyone.

Indoor Shrimp Farming: A New Market?

Recently, shrimp surpassed tuna as the most-consumed seafood in the
United States. Most of the shrimp Americans eat is produced in
Southeast Asia, India, Mexico and Brazil. Russ Allen wants to change
that. He’s opened one of the world’s few indoor shrimp farms in the
Midwest. Allen says his operation meets an obvious market demand, is
good for the environment, and presents a new economic opportunity for
the country. The Great Lakes Radio Consortium’s Erin Toner reports:


In a big blue barn in Russ Allen’s backyard, there are thousands of
shrimp… beady-eyed, bacteria-munching, bottom-feeders.


Here, the life cycle of the shrimp starts in the breeding center, where
two big tanks of water mimic a place 150 feet deep off the shore of the
ocean where the water quality and temperature are stable. Allen says
it’s the perfect environment for shrimp to mate.


“Like in just about all animals the male chases the female, and they do a
little courtship dance, and then the male will deposit a spermatophore on
the female and when she spawns, the eggs pass through the
spermatophore, are fertilized and then go out into the water.”


A few months later, the shrimp end up in the production room where all
they do is eat, and sometimes, if they get excited or spooked, they jump
right out of their tanks.


“They don’t like light…”


“Oh (laughing)! Do you ever have them hit you as you’re standing
here?”


“Oh yeah, that’s why we have the nets up so they don’t jump.”


Russ Allen has been farming shrimp for three decades. He started in
Ecuador, and then went to Belize, where he started the country’s first
shrimp farms.


Allen and his wife moved back to Michigan in 1990, when he started
designing his indoor shrimp farm. It finally opened for business about a
year ago, and now, he’s selling all the shrimp he produces.


(Sound of shrimp market)


Allen says his indoor shrimp farm is one of the first of its kind in the
world. There’s no waste leaving his farm, so pollution’s not an issue,
and because there’s no water coming in or going out, there’s no danger
of introducing diseases into his system.


Allen says an indoor farm also moves shrimp farming away from fragile
coastal ecosystems. That’s where most of the industry has developed
around the world.


“In a place like the United States with all the development on the
coastline and land costs, you can’t really do it anywhere near the ocean
anyway. So, if you’re going to have a viable shrimp farming system in
the United States, you need to move it away from – you know – these coastal areas.”


But indoor farms haven’t always been a viable option, either.


In the 1980s, a handful of them opened in the U.S., including a big one in
Chicago. They all failed because the technology didn’t work quite right,
and because the cost of production made them unable to compete with
outdoor farms.


Bill More is a shrimp farming consultant and vice president of the
Aquaculture Certification Council. He says now, indoor shrimp farmers
have a better chance of making a go of it.


“Coming from third-world countries, there’s been a lot of issues with
illegal antibiotics being found in shrimp. There’s been environmental
and social issues that environmentalists have come down hard upon. It’s
sort of prompted the opportunity for a good indoor system where
you could manage those and you didn’t challenge the environment.”


But More says creating and maintaining a clean, organic indoor shrimp
farm is still very expensive, and it seems an even bigger problem now
that the price of shrimp is the lowest it’s been in a decade.


Shrimp farmer Russ Allen says he’s invested several million dollars in
his business. He’s the only guy in the game right now, which he
admits is good for business, but he doesn’t want it that way. He says
he’d like to see the industry grow in Michigan, and throughout the
country.


“In order to do that the government has got to be a partner in this, and
that has been the challenge… that when you don’t have an industry, you
don’t have lobbyists and nobody listens to you and you can’t get an
industry until they do listen to you. So, that’s been our real challenge
right now.”


Allen says he wants the government to offer tax breaks and other
financial assistance to the aquaculture industry like it does to other
sectors of the economy, but he says he can’t even get some local elected
officials to come and see his shrimp farm. He says with so many
companies moving jobs and factories overseas, he thinks government
leaders should be looking for ways to help new and perhaps
unconventional industries like his, grow.

Congress already backs cleanup plans, such as the one in Chesapeake

One advocacy group says the track record’s unclear. A report by the

Author Karen Vigmostad says Congress starts projects, but doesn’t
always stay committed.


She cites the Florida Everglades.


“There’s been some planning money, but in terms of actually
implementing the plan, the money has not been forthcoming. The state
of Florida’s pretty much been footing that bill.”


The Great Lakes restoration plan faces its first major hurdle soon.
President Bush will release his budget by February. Great Lakes

Trash Burning Can Threaten Human Health

  • Burning trash smells bad and it can create the conditions necessary to produce dioxin. If livestock are exposed to that dioxin, it can get into the meat and milk we consume, creating health risks. (Photo courtesy of the Minnesota Office of Environmental Assistance)

For most of us, getting rid of the garbage is as simple as setting it at the curb. But not everyone can get garbage pick-up. So, instead, they burn their trash. The Great Lakes Radio Consortium’s Lester Graham reports… that choice could be affecting your health:

For most of us, getting rid of the garbage is as simple as setting it at the
curb, but not everyone can get garbage pick-up. So, instead, they burn
their trash. The Great Lakes Radio Consortium’s Lester Graham
reports… that choice could be affecting your health:


(Sound of garbage trucks)


It’s not been that long ago that people everywhere but in the largest cities
burned their trash in a barrel or pit in the backyard. That’s not as often
the case these days. Garbage trucks make their appointed rounds in
cities, small towns, and in some rural areas, but they don’t pick up
Everywhere, or if they do offer service, it’s much more expensive
because the pick-up is so far out in the country.


Roger Booth lives in a rural area in southwestern Illinois. He says
garbage pick-up is not an option for him.


“Well, we burn it and then bury the ashes and things. We don’t have a
good way to dispose of it any other method. The cost of having pick up
arranged is prohibitive.”


He burns his garbage in the backyard. Booth separates bottles and tin
cans from the rest of the garbage so that he doesn’t end up with broken
glass and rusty cans scattered around.


A lot of people don’t do that much. They burn everything in a barrel and
then dump the ashes and scrap in a gully… or just burn everything in a
gully or ditch. Booth says that’s the way most folks take care of the
garbage in the area. No one talks about the smoke or fumes put off by
the burning.


“I haven’t ever thought much about that. So, I don’t suppose that I have
any real concerns at this moment. I don’t think I’m doing anything
different than most people.”


And that’s what many people who burn their garbage say.


A survey conducted by the Zenith Research Group found that people in
areas of Wisconsin and Minnesota who didn’t have regular garbage
collection believe burning is a viable option to get rid of their household
and yard waste. Nearly 45-percent of them indicated it was
“convenient,” which the researchers interpreted to mean that even if
garbage pick-up were available, the residents might find more convenient
to keep burning their garbage.


While some cities and more densely populated areas have restricted
backyard burning… state governments in all but a handful of states in
New England and the state of California have been reluctant to put a lot
of restrictions on burning barrels.


But backyard burning can be more than just a stinky nuisance. Burning
garbage can bring together all the conditions necessary to produce
dioxin. Dioxin is a catch-all term that includes several toxic compounds.
The extent of their impact on human health is not completely know, but
they’re considered to be very dangerous to human health in the tiniest
amounts.


Since most of the backyard burning is done in rural areas, livestock are
exposed to dioxin and it gets into the meat and milk that we consume.


John Giesy is with the National Food Safety and Toxicology Center at
Michigan State University. He says as people burn garbage, the dioxins
are emitted in the fumes and smoke…


“So, when they fall out onto the ground or onto the grass, then animals
eat those plants and it becomes part of their diet, and ultimately it’s
accumulated into the animal and it’s stored as fat. Now, particularly with
dairy cattle, one of the concerns about being exposed to dioxins is that
then when they’re producing milk, milk has fat it in, it has butter fat in it,
and the dioxins go along with that.”


So, every time we drink milk, snack on cheese, or eat a hamburger, we
risk getting a small dose of dioxin. Beyond that, vegetables from a
farmer’s garden, if not properly washed, could be coated with dioxins,
and even a miniscule amount of dioxin is risky.


John Giesy says chemical manufacturing plants and other sources of
man-made dioxin have been cleaned up. Now, backyard burning is the
biggest source of dioxins produced by humans.


“So, now as we continue to strive to reduce the amount of dioxins in the
environment and in our food, this is one place where we can make an
impact.”


“That’s the concern. That’s the concern, is that it’s the largest remaining
source of produced dioxin.”


Dan Hopkins is with the Environmental Protection Agency. He says,
collectively, backyard burning produces 50 times the amount of dioxin as
all the large and medium sized incinerators across the nation combined.
That’s because the incinerators burn hot enough to destroy dioxins and
have pollution control devices to limit emissions. Backyard burning
doesn’t get nearly that hot and the smoke and fumes spread unchecked.


The EPA wants communities to take the problem of backyard burning
seriously. It wants state and local governments to do more to make
people aware that backyard burning is contaminating our food and
encourage them to find other ways to get rid of their garbage.


“(It) probably won’t be a one-size-fits-all solution, but by exchanging
successful efforts that other communities have had, we should be able to
help communities fashion approaches that have a high probability of
success.”


But public education efforts are expensive, and often they don’t reach the
people who most need to hear them. The EPA is not optimistic that it
will see everyone stop burning their garbage. It’s not even a goal. The
agency is just hoping enough people will find other ways to get rid of
their trash that the overall dioxin level in food is reduced.

Ten Threats: Concrete Shores

  • Hardened shorelines protect buildings, roads, and homes, but many developers say a more natural method should be used. (Photo by Lester Graham)

Along many Great Lakes cities, long concrete or stone seawalls protect property against
wind and wave erosion. It’s a hardening of the shoreline that some people say is
necessary to protect expensive real estate. But some scientists and environmentalists say

seawalls are not only hurting the environment… in the long run, they’re hurting the
economy. Lynette Kalsnes has this report:

Transcript

In our series ‘Ten Threats to the Great Lakes,’ we’ve been looking at how humans make
changes that affect the health of the lakes. Lester Graham is our guide through the series.
He says the next report shows how far we’ll go to try to manage nature:


Along many Great Lakes cities, long concrete or stone seawalls protect property against
wind and wave erosion. It’s a hardening of the shoreline that some people say is
necessary to protect expensive real estate. But some scientists and environmentalists say
it’s part of one of the ‘Ten Threats to the Great Lakes. They’re worried those concrete
seawalls are not only hurting the environment… in the long run, they’re hurting the
economy. Lynette Kalsnes has this report:


(waves lapping against concrete wall)


In the middle of a miles-long concrete shoreline, there’s a tiny beach. Steve Forman points
toward a small bluff at the base of a tree. The professor of earth and environmental sciences at
the University of Illinois at Chicago says the sand, grass and dunes help soften the impact of
waves and rain.


“This kind of relief is what you’d see in many natural coastlines, a coastline like this can
accommodate change better than one that’s been concreted up.”


Just feet away, the concrete picks back up, like a stark white runway that bisects the land and the
lake. Concrete revetments like these in Chicago are a familiar sight in urban areas across the
Great Lakes.


Roy Deda is with the U.S. Army Corps of Engineers. The Corps manages much of the
construction on public shorelines. Deda says hardening the shore is one way of protecting against
erosion.


“Where hardening of the shoreline is important and used, is where you have an existing
community in an urban area like Chicago. You have a lot of development in place already, and
basically you’re protecting what’s been built over a long history.”


Deda says it protects property. But scientist Steve Forman says using concrete walls comes at a
cost: the destruction of natural systems that are often helpful.


Forman says wetlands and stream valleys normally act like a sponge to absorb high lake levels.
They also release some of the water back when lake levels are low. Forman says concrete can’t
buffer those fluctuations.


“It makes the extremes potentially even more extreme in terms of lake level variations.”


So, when there’s a rainstorm, Forman says the water runs off the concrete quickly… instead of
being absorbed across sand or wetlands slowly.


He says the same thing is true for the water flowing into the lakes from rivers.


Discharge into rivers can go up by 50 times the amount it would if natural areas buffered the
rivers.


“Any time we change the landscape from its natural components, we also change the plumbing of
the Great Lakes. We change the way water is routed in and around and through the Great Lakes
as well.”


It’s not only rushing rivers and lake levels that cause problems.


When the shoreline is hardened… the wildlife and organisms that once lived there disappear.


Cameron Davis is with the Alliance for the Great Lakes. He says many rare species live in that
narrow ribbon where the land meets the water.


“When we harden the shorelines, we basically sterilize them in a lot of ways, because we’ve not
providing the kinds of habitat and cover that we need for many of them.”


And beyond the effect on wildlife… hardening the shoreline can also be a bad economic decision.


Steve Forman says permanent structures built near the shores are not as stable as they might seem
when lake levels are high and winter storms cause big waves that erode the land underneath them.


“When the lake levels go up, the erosion rates are just phenomenal…what you see are hanging
stairs everywhere, instead of stairs that take you down to the beach, they’re hanging over the lake,
basically.”


That’s why scientists and planners are taking action. The Alliance for the Great Lakes’ Cameron
Davis is calling on planners to balance protecting the shoreline … with preserving ecology.


“Frankly I don’t think shoreline planning across the region is that great. There really is no single
unifying policy we’re all using to guide what our shorelines ought to look like.”


He’s hoping that some cities will experiment with restoring natural areas along their shorelines…
He says we need to see if in the long run, nature can do a better job of protecting the shores.

The provision in question requires the utilities to install new and
expensive controls if the improvements result in increased air
pollution. The question is – how do you determine if there’s more
pollution?


Should it be measured as an annual total? – the current method – or by
the hour? – the proposed method.


Melissa McHenry is a spokeswoman for American Electric Power, one of
the biggest power producers in the nation…


“We support the EPA’s proposal because it provides clarity. It also
makes the rule consistent with the emissions test for other Clean Air
Act rules.”


But environmentalists claim the draft regulation would make it easier
for plants to avoid installing pollution controls.


One clean air advocate says the proposed EPA rule would lead to tens of
thousands of premature deaths by 2025.

New Energy Billing Program to Save Money?

Most power companies charge customers a single, flat rate for electricity. But one group of volunteers is experimenting with a new system. They say people might save money by changing how they’re charged for power. The Great Lakes Radio Consortium’s Shawn Allee has this report:

Most power companies charge customers a single, flat rate for electricity. But one group of volunteers is experimenting with a new system. They say people might save money by changing how they’re charged for power. The Great Lakes Radio Consortium’s Shawn Allee has this report;


Two years ago, the Illinois-based Community Energy Cooperative, struck a
deal with Com-Ed, the local power company. Instead of getting charged a single rate, members pay more when the energy supply is tight, like on a hot summer’s day.


In exchange, they get a break when there’s less demand. Co-op manager Kathryn Thowlin says a website warns members when power prices rise.


“They can see when it’s the most expensive, when its least expensive.
So somebody who really wants to fine-tune their energy use based on price has
some really easy-to-use tools to do that.”


Thowlin says it’s paid off: consumers have saved about 11 percent on their
power bills.


The experiment is the most comprehensive of its kind offered to residential
customers. Environmentalists say the program works best when consumers cut their
overall demand, not just shift when they use power.

States Sue Epa Over New Mercury Rules

Several states are filing a lawsuit against the U.S. Environmental
Protection Agency for its recently announced rules for reducing mercury
pollution. The states allege the EPA’s rules do not adequately protect
children and pregnant mothers from mercury contamination. The Great Lakes
Radio Consortium’s Lester Graham reports:


Nine states joined in the suit, claiming the EPA’s new cap-and-trade program
would lead to mercury hotspots. Instead of making all coal-burning plants
reduce mercury emissions, the plan will allow some plants to continue to
pollute by buying credits from plants that reduce emissions below the EPA’s
targets.


Peter Harvey is the Attorney General for New Jersey. He’s the lead
plaintiff in the suit.


“There are going to be areas of the country that have a lot more air
pollution, which means those residents are at a greater danger of ingesting
mercury, either through the air or through seafood products.”


Harvey says the Bush Administration’s plan does not meet the requirements of
the Clean Air Act. The U.S. EPA has defended the plan in the past, saying
lowers overall mercury emissions by half within 15 years without forcing
companies to add expensive pollution prevention equipment at every plant.


For the Great Lakes Radio Consortium, this is Lester Graham.
