The federal government’s tougher regulations on pollution might have consequences on prices at the gasoline pump. To meet the Clean Air Act, some areas might be required to use cleaner-burning fuels. That could make it tougher to get gasoline supplies where they need to be. And that could mean higher prices. The Great Lakes Radio Consortium’s Lester Graham reports:

The federal government’s tougher regulations on pollution might have consequences on prices at
the gasoline pump. To meet the Clean Air Act some areas might be required to use cleaner-
burning fuels. That could make it tougher to get gasoline supplies where they need to be. And
that could mean higher prices. The Great Lakes Radio Consortium’s Lester Graham reports:


The Environmental Protection Agency says 31 states are not complying with the Clean Air Act.
The EPA indicates tougher standards for ground-level ozone make many areas that didn’t know
they had a problem in violation of air pollution laws.


John Mooney is an environmental specialist with the EPA. He says the government used to
check for ozone pollution for short periods… but started monitoring for longer periods and found
more instances of high levels of ozone.


“The other issue is that we’re changing the number of the standard from 120 down to 80 parts-
per-billion. So, it’s a lower level that we’re looking at. And we think that’s more reflective of
the health effects that are being caused by this pollutant.”


Ground-level ozone aggravates asthma. People with lung diseases can find it hard to breathe.
And those who work outdoors are affected by the unhealthy air.


Ozone is created when factories and cars emit volatile organic compounds. That chemical stew is
affected by sunlight and ozone can form. Cities that have had high ozone levels have worked to
reduce emissions from businesses, encouraged car-pooling, made announcements asking people
not to use gas-powered mowers on high ozone days.


And… for some cities… part of the solution has been reformulated gasoline. It’s gas that’s
cleaner burning. Different formulations are used in different areas. And… gas formulas change
from winter to summer. Refineries and gasoline suppliers have to empty their tanks and pipelines
before switching. That makes gas supplies tight for a while and that drives the price up. We
asked the EPA’s John Mooney about that.


LG: We’ve got several cities with reformulated gasoline right now and that’s put a strain on the
distribution system nation-wide. If more cities have to start using reformulated gasoline and each
city has to have a different formulation, that’s going to further strain the distribution problem at a
time when gasoline prices are at an all time high.


JM: “We’re extremely sensitive to the infrastructure issue and the energy issue and are trying to
promote clean-burning fuels that have environmental impacts without significant economic
disruptions. Having fuel shortages and price spikes and things of that nature don’t contribute to
the success of our mission to improve public health. And so, we’re going to be tied into the fuel
distribution issues and we’re going to be working with the oil refiners to make sure that the fuels
programs that are ultimately decided upon operate without significant disruptions.”


Significant disruptions that could cause gasoline shortages and high prices.


Bob Slaughter is the President of NPRA, the National Petrochemical & Refiners Association. He
says the government needs to work closely with gasoline suppliers to make sure that efforts to
make the air easier to breathe don’t make problems for the economy of an area.


“You know, you have to be very careful that you don’t have so many fuels in certain areas that it
becomes difficult to re-supply if there are problems, say, with a refinery or a pipeline in a
particular area.”


For instance, in recent years a fire at a refinery at a bad time meant shortages and higher prices.


But… even with lots of cooperation between government and the gasoline suppliers, the added
burden of different types of reformulated gasoline to the fuel distribution system might mean
spikes in gas prices.


(road sound, gas station)


We asked some people buying gas if they were willing to pay more if it meant cleaner air…


VOXPOP (voice 1) “Well, the gas prices are high enough. Uh, am I willing? I suppose so if it’s
better for the environment.” (voice 2) “Well, I think the federal government regulates everything
way too much right now. I think they do have a lot of safeguards in place right now to lower the
emissions in a lot of vehicles. Why do we have to make further regulation to control that?”
(voice 3) “I mean, I hate to – I hate to pay more gas prices. I really do. But, I guess for cleaner
air, it might be worth it.” (voice 4) “I haven’t thought about it too much. I pay what they make
me pay. I don’t care.”


The EPA is giving states and cities three years to get their ground-level ozone pollution problems
below the government’s new standards.

Automakers Divided Over Lead Wheel Weights

For years, the government and environmentalists have been working to reduce lead exposure in the
environment. Lead can cause developmental damage to children and cause other health problems. The
government banned lead in gasoline. It banned lead shot in shotgun shells. There are efforts to get rid of lead
sinkers in fishing tackle. And now, environmentalists are trying to ban lead weights used to balance wheels.
And some companies and fleet operators seem willing to comply. The Great Lakes Radio Consortium’s Julie
Halpert has the story about the move to a less hazardous alternative:


When you buy a new car or get your tires replaced, manufacturers use lead weights, which clip onto the wheel
rim to make sure it’s evenly balanced. They use lead, because it’s heavy, dense. So a small amount by
volume is used.


Still, a few ounces of lead can be used on each wheel. And nearly every car and truck on the road has lead
weights. They’re the second largest use of lead in cars, next to lead acid batteries.


As long as the weights stay on the tires, they’re not a huge problem. But environmentalists are worried that
they come off too often. Many fall off when a car hits a pothole or collides with a curb. Then they’re run
over, ground down and get into the environment.


Each year, roughly 30-million pounds of lead are used to make wheel weights. A recent study estimates that
more than 300 tons of lead fall off vehicles each year in the Midwest alone. Jeff Gearhart is with the Ecology
Center which conducted that study.


“Many people don’t realize there’s a lot of lead in vehicles for this particular use and this is actually a fairly
small percentage of that lead actually falls off. But when you look at it as quantity, it’s pretty significant.”


The weights don’t just pose a problem on the road. Gearhart says there’s also danger when they’re not
properly recycled when new tires are put on and the weights are replaced. Another problem is when a car is
scrapped and then later when the parts are melted down, the lead can be released into the environment.

“Lead wheel weights are not managed very well as vehicles are scrapped and the difficulty in correcting the
management of these at the end of a life in a salvage yard or in a vehicle crusher or a shredder is very
challenging.”


He says the solution is to make sure lead is not used in the first place. Concerned about lead’s potential
health effects, Europe has already decided to ban lead wheel weights starting next year. And Gearhart is
pushing manufacturers who design for the U.S. market to do the same. He says substitute materials, such as
zinc, iron and tin, are readily available and work just as well as lead.


And with funding from the Environmental Protection Agency, the Ecology Center is making lead-free weights
available to those who service vehicle fleets.


(sound of weights being hammered onto wheel rims)


At the city of Ann Arbor, Michigan’s garage, a technician is banging zinc weights onto wheels. Tom
Gibbons helps manage this fleet of 400 city vehicles. Ann Arbor is the first city to switch to lead-free
weights.


“We realize lead is a problem in the environment and in the city, we’re really concerned about the
environment. We’re committed to doing as much as we can to protect it, so if we can take lead out of the
system, why not do it.”


Gibbons says the substitutes work just as well as lead weights. He says once the Ecology Center’s free
supply of weights runs out, the city will began buying non-lead weights, even though they’ll cost slightly
more.


But not everyone agrees with the idea of using other materials for wheel weights. Daimler/Chrysler doesn’t
plan to switch to lead-free weights for its U.S. models. The company is concerned the substitutes are costlier
and more difficult to install on wheels.


Other automakers are looking at eliminating the use of lead weights. Terry Cullum is with General Motors.
He agrees they’re currently an issue, but says the Ecology Center’s estimate of the number of weights that fall
off cars seems high to him. And, he says there’s no imminent danger to the public.

“I think if you look at this from a risk-based situation, we don’t view lead being used in wheel weights
applications as a risk, well, as a large risk, let’s put it that way.”


Even so, General Motors is considering moving to lead free weights. Cullum says that everywhere the
automaker uses lead is a concern. And since the company will have to stop using lead weights on the cars and
trucks it sell in Europe, he says it might be easier just to take them out of all GM vehicles. Still, Cullum says
the substitutes present a big engineering challenge: because they’re not as dense. It takes bigger pieces of
metal to make the same weight. So, they take up more space on the wheel than lead weights.


“It becomes an issue, in terms of where do you put it on the wheel, how do you do it in such a way that it
doesn’t actually interfere with the actual operation of the wheel or the brake systems. That is an issue that is
going through research and engineering right now.”


But Cullum’s optimistic that the issue can be addressed. And other auto makers, such as Honda, are forging
ahead with lead-free weights on at least one of their model.


Still there’s resistance from U.S. tire retailers. The Tire Industry Association says the weights don’t fall off
wheels. And the tire retailers say the lead weights are properly recycled. The group has no plans to stop
using lead weights if they’re not legally required to.


Jeff Gearhart with the Ecology Center says that denial of the problem is a big mistake. He says if
manufacturers and tire retailers cooperated, they could get a substantial amount of lead out of the
environment within a few years.


“There is the potential to make a really significant impact here. We’re talking hundreds of tons of lead
released into the U.S. to the environment that can be eliminated. So we think this is a high priority project,
not just for us, but we think it will be for states and for EPA to look at how to facilitate this transition to
cleaner wheel balancing.”

The Environmental Protection Agency is starting to look at the issue. It plans to conduct a study within the
next year to get a better understanding of the problem and see how lead weights are handled. Then, they’ll
issue guidelines for consumers and tire recyclers late next year. That means the public will be more aware of
the use of lead wheel weights and the potential for toxic exposure. Usually, that means public pressure for
change, whether some automakers and tire retailers like it or not.

Study: Banned Pesticides Affect Child Development

Columbia University professors say they have found the first evidence that two banned pesticides
are harmful to humans. They say their study vindicates a decision by the Environmental
Protection Agency to phase out the chemicals based only on preliminary research on animals.
The Great Lakes Radio Consortium’s Tracy Samilton reports:


Chlorpyrifos and diazinon were once found in over-the-counter products for
in-home pest control. The EPA started to phase out the chemicals four
years ago, after preliminary research showed the chemicals could be
harmful. The new study tracked a group of pregnant women in New York
before, during and after the ban. It found that women with the highest
concentration of the pesticides in their blood had smaller and shorter
babies than those with less exposure. Robin Whyatt is with Columbia’s
Mailman School of Public Health. She led the study. She says there’s no
question the research vindicates the EPA’s decision.


“It certainly supports that that was a good regulatory decision and this also shows that regulation
works.”


While Whyatt says the ban was good policy, she says more studies should be
done to confirm her results. Chlorpyrifos and diazinon are still widely
used in agriculture. Some environmental groups say the chemicals should
also be phased out there.

(tire balancing sound)


When you go to get new tires, or to have them rebalanced, the mechanic often
attaches lead weights to the wheel rims. The weights help ensure a smooth
ride and make sure tires wear evenly.


But two recent studies found some of these wheel weights fall off. The
researchers say that adds up to 275 tons of lead dropped onto roads in the
region every year. One of the studies found the soft metal gets ground up
and deposited near curbs.


Jeff Gearhart is with the Ecology Center. His group is concerned the lead
dust could be tracked into homes and washed into water supplies. So the
group is working with tire retailers to switch to non-lead wheel weights.


“Lead, in commerce, being used in a way where there’s exposure, is something
we should move away from. The European Union has banned the use of these
weights and we think that that is going to be needed in the U.S. as well.


Gearhart says the Ecology Center will help retailers cover the cost of
switching to non-lead weights.

Report: E-Waste Piling Up

As electronic devices are becoming faster, smaller and cheaper, many consumers are opting to scrap their old, outdated computers and televisions for the latest technologies.

As electronic devices are becoming faster, smaller and cheaper, many consumers are opting to
scrap their old, outdated computers and televisions for the latest technologies. But as a recent
report shows, as people throw out these products, a new legacy of waste is piling up. The Great
Lakes Radio Consortium’s Erika Johnson reports:


Electronic waste – or e-waste – is what ends up in landfills when people throw away electronic
devices such as computer monitors and television sets. The report by the Silicon Valley Toxics
Coalition tracked the amount of e-waste that ends up in landfills. Researchers found there’s more
e-waste than waste from beverage containers and disposable diapers. Electronic products can
threaten human health because they contain toxic heavy metals.


Sheila Davis headed up the Coalition’s report:


“People are starting to sit up and take notice and especially when you start having large volumes
of the material. So many states are taking notice. For example, California, Massachusetts,
Minnesota and Maine have all banned these products from landfills, e-waste from landfills.”


Yet Davis says many people in other states end up pitching their used electronics because many
recycling programs are often inconvenient and expensive.


But for now, Davis suggests people contact their local governments for more information on
where to take their used electronics.

Cleanup of Toxic Sites in Limbo

Monsanto has agreed to clean up one contaminated site of hundreds that need to be cleaned up. The toxic site cleanups have been in limbo because of a recent bankruptcy. The Great Lakes Radio Consortium’s Tom Weber explains:

Monsanto has agreed to clean up one contaminated site of hundreds that need to be cleaned up.
The toxic site cleanups have been in limbo because of a recent bankruptcy. The Great Lakes
Radio Consortium’s Tom Weber reports:


Monsanto contaminated this one site in southern Illinois with dioxins, PCB’s and other toxic
chemicals for 40 years.


Legal questions arose because Monsanto created a company called Solutia in 1997. Solutia took
responsibility for Monsanto’s chemical clean ups. But Solutia went bankrupt last year. And it
refused to clean any of the 300 sites across the country while in bankruptcy.


Glenn Ruskin is a Solutia spokesman. He says Solutia can’t clean up the site, but Monsanto’s
decision to do so offers hope for people who live at the other sites.


“It just indicates that there are parties out there who are still in existence that are willing and able
to do that clean up.”


The matter is even more complex because much of Monsanto was bought by Pharmacia. Pfizer
then bought Pharmacia.


A bankruptcy judge will ultimately decide who has to clean which sites.

Epa Tightens Rules on Slaughterhouse Waste

It takes a lot of work to turn a cow or chicken into a hamburger or chicken nuggets. And the
process creates a lot of waste. Now, the Environmental Protection Agency is aiming to reduce
the pollution that’s released into rivers, lakes and streams. The Great Lakes Radio Consortium’s
Rebecca Williams has more:


The EPA estimates meat and poultry processors use 150 billion gallons of water every year.
Most of that water becomes wastewater. That wastewater can contain oil, blood, manure, and
feathers.


If the wastewater isn’t treated, organic wastes and nutrients are released directly into waterways.
Excess nutrients can cause harmful algae blooms, and kill fish.


The new rule targets about 170 meat and poultry processors.


Mary Smith directs a division of the EPA’s Office of Water.


“The meats industry will have to meet tighter limits on the pollutants that it discharges to the
water. And then, of course, for poultry, this is the first time they will be regulated at all, they
didn’t have preexisting regulations, unlike the meats industry. And they will have to meet limits
for ammonia, total nitrogen, and what we call conventional pollutants.”


These regulations are a result of a lawsuit against the EPA, settled 13
years ago.

Poultry Farmers Protect Flocks From Avian Flu

Poultry farmers in the Midwest are taking extra precautions after the discovery of avian flu among chickens in Pennsylvania and Delaware, but there are some things the industry can’t control, as the Great Lakes Radio Consortium’s Tracy Samilton reports:

Transcript

Poultry farmers in the Midwest are taking extra precautions after the discovery of avian flu
among chickens in Pennsylvania and Delaware. But there are some things the industry can’t
control, as the Great Lakes Radio Consortium’s Tracy Samilton reports:


Most commercial poultry farmers practice state-of-the-art biosecurity because of what’s at stake.
Some avian flu is relatively harmless, but if a lethal variety breaks out, the farmer’s entire flock
has to be destroyed. So birds are isolated from contact with visitors and delivery trucks, and
workers frequently change clothes and disinfect their shoes.


Paul Wiley is with Michigan State University’s agricultural extension service. He says
that’s not the case with city émigrés to the country who raise chickens as a hobby.


“The first thing they want to have is two horses, the second thing they want is some kind of flock
of poultry, and they are clueless about poultry!”


Wiley says more backyard flocks could threaten the health of the large commercial flocks. Still,
he says the situation is not nearly as bad as in some Asian countries. There, birds are sold live at
markets, which brings them into frequent contact with people, other birds and wild animals.

Old Chlorine Plants Lose Track of Mercury

The Environmental Protection agency is accused of ignoring the disappearance each year of tons
of mercury at several processing plants. The Great Lakes Radio Consortium’s Lester Graham
reports:


The plants make chlorine. Part of the process at these older plants involves putting an electric
current through big vats of mercury. Every year the plants buy tons more mercury, but don’t
report that it escapes as emissions. Three environmental groups have sued the EPA, saying the
agency isn’t protecting the public’s health when it allows that much mercury to just disappear.


Jim Pew is a lawyer with one of the groups, Earthjustice.


“The very simple question that came up is, ‘Gosh, where is all this mercury going?'”


“And nobody seems to be able to answer that?”


“No. The Environmental Protection Agency gave it a little bit of thought and then declared that –
and this is a quote, “…somewhat of an enigma.”


Mercury can cause neurological damage to humans. Fetuses and young children are especially at
risk. The environmental organizations want the EPA to find out what happens to all that mercury
and require the older plants to modernize to a process that doesn’t need mercury to make
chlorine.

Raw Milk Advocates Petition Small Farmers

For decades a small number of people have believed milk is more nutritious if it’s
not pasteurized. Modern science doesn’t support that claim. And the idea of milk
going right from the cow to the breakfast bowl is unthinkable for most doctors and
food safety experts. But advocates are finding a new audience for their message:
Small farmers trying to compete against large dairy companies. The Great Lakes
Radio Consortium’s Peter Payette reports:


A thick white blanket of fresh snow covers Chris Halpin’s small farm in northern
Michigan. All his goats are in the barn this morning munching on hay.


“These girls in here are all in here with a billy goat and they’re all milking
right now and they’re waiting to get bred. That’s the billy there.”


Halpin hasn’t sold much milk, even though he’s been raising goats for a number of
years. He says small farmers must cut out the middleman to make a living and
he’s exploring options to sell milk products without going through a big dairy
company.


Pasteurization equipment is too expensive for his small farm. So, for the last two
years he’s sold un-pasteurized milk to a small number of people.


“The demand for raw milk is huge. Pasteurized milk is a dead product. It’s
dead. It’s heated up to temperatures that kills not only any the bacteria that
could be in the milk but it kills all the enzymes in the milk and so there’s nothing
in there that could promote the body to digest the milk.”


It’s not legal to sell the raw milk in Michigan. A few other Midwest states and
Canada also ban such sales. Health officials say that raw milk can carry food-
borne illnesses. But Halpin says his animals are clean and healthy and he has no
concerns about the safety of the milk.


“That’s not my concern at all. We have five children and my wife makes yogurt
and cheese and we drink raw milk and I have no concerns at all and I don’t have
no concerns for my own family. If I guy has concerns it seems like it’d be for his
own family.”


Food regulators say the dangers of raw milk are well documented. In 2001, for
example, an outbreak of a bacterial infection in Wisconsin sickened 19 people.
The state says 17 of them reported drinking raw milk.


And raw milk advocates have not been able to convince regulators that raw milk
has any nutritional benefit over pasteurized milk, as is often claimed.


The legislative liaison for the Michigan Department of Agriculture, Brad Deacon,
says opponents of the pasteurization requirement weren’t persuasive when his state
updated its dairy laws in 2001.


“There haven’t been any credible studies that we’ve been able to find. Our minds
are not closed on the matter. But we’ve been yet to be given any credible studies
that pasteurized milk has fewer nutrients than unpasteurized milk.”


Raw milk advocates point to older studies, mostly done in the first half of the
twentieth century. Those studies did suggest health benefits from drinking raw
milk.


And they have anecdotal stories of people overcoming health problems by
switching to a diet that includes raw dairy.


They say the scientific community’s view is entrenched and influenced by the
interests of big agribusiness and big dairies.


But with modern science against them, raw milk activists are taking their message
directly to farmers.


And they’re finding receptive and occasionally large audiences.


The President of the Weston A. Price Foundation — the national group leading the
campaign for raw milk — was recently the keynote speaker at a small farm
conference in the Midwest that attracted 600 people.


Sally Fallon told the farmers they’re up against corporations that want squeeze the
little guy out.


“For this to happen, she says the big companies must make sure all food goes
through the corporations on its way from the farm to the table.”


“The farmer who adds value by farming organically by making cheese or butter
or by simply selling directly to the consumer, he is the enemy to this system and a
whole battery of laws, health laws, licensing laws, even environmental laws, is
used against us. We need to get rid of some of these laws.”


Fallon says raw dairy products are good for the consumer and the bottom line of
the farm.


For instance, she says raw butter made from cows free roaming on fertile pasture
is “the number one health food in America.”


The farmer making this butter should get at least five dollars a pound for this
product. In Washington D.C., we’re getting ten dollars a pound for the beautiful
Amish butter. Now that kind of income will pay for lots of improvements on the
farm.”


But the plight of small farmers doesn’t change the facts, says Dr. Stephen Barrett,
a retired psychiatrist and journalist who operates the website quackwatch.org.
Barrett says small businesses are having trouble everywhere.


“One have to ask rather cynically, if a company isn’t viable in the marketplace,
they either better do something or they’re going to perish, and if doing something
means putting the public at risk, that’s not good.”


Good or not, activists will continue to push for what they see as a fundamental
right to drink and sell milk without interference from the government.
