The Environmental Protection Agency is proposing a new rule
on aluminum production that could trade one kind of
pollution for another. Dustin Dwyer reports that some are
skeptical of the plan:


When you make aluminum for vehicles, there’s a leftover
sludge that can include some toxic chemicals. The EPA wants
to loosen regulations on that sludge.


It says that could encourage more auto manufacturers to use
aluminum instead of steel in vehicle bodies, and since
aluminum is lighter than steel, those vehicles would burn
less gas. Don McKenzie of the Union of Concerned Scientists
says he’s not sure it’s a good idea:


“Aluminum can help to get us more efficient vehicles. But we
shouldn’t need to be changing the rules around aluminum
production to get aluminum into vehicles.”


McKenzie says if the government imposed stricter fuel
economy standards, and kept the rules on aluminum sludge in
place, more automakers would be forced to use aluminum
anyway.

The fish and wildlife agency already has announced plans to
cut more than 250 jobs over the next three years. Further
cuts are expected soon.


The agency blames a flat budget and rising operational and
personnel costs, but Jeff Ruch of Public Employees for
Environmental Responsibility says visitors to the affected
refuges will find a less enjoyable experience at no real
savings in tax dollars:


“All the cutbacks in the refuge system are less than what
we’re spending in Iraq in a day. I mean to put it in some
perspective, we’re talking about literally millions of
dollars versus billions of dollars that are being
hemorrhaged out of other government operations.”


Democratic Congressman Ron Kind co-chairs a caucus on
wildlife refuges. He says he’ll try to address the job cuts
in the next federal budget.

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.

‘ODOR PATROL’ SNIFFS OUT POLLUTION

The world’s largest automaker is doing something it’s never done before. General Motors is recruiting people who live near its assembly plants to help the company find ways to pollute less.

The world’s largest automaker is doing something it’s never done before. General Motors is
recruiting people who live near its assembly plants to help the company find ways to pollute less.
But as the Great Lakes Radio Consortium’s Erin Toner reports, some environmentalists say GM’s
efforts are missing the point.


The city of Lansing, Michigan is the car Capital of North America, producing nearly a
half-a-million Pontiacs, Oldsmobiles, Chevrolets and Cadillacs every year. Later this year,
General Motors adds another car to its Lansing lineup – a brand-new Chevy roadster. But it
almost didn’t happen.


Environmentalists threatened legal action to block production because they weren’t satisfied with
the factory’s air pollution controls.


Steve Tomaszewski is General Motors’ Lansing environmental manager.


“People were concerned, everyone was concerned. There was a breakdown of communications,
on all parties.”


The disagreement was over air pollution from one of GM’s plants. Those emissions were due to
nearly double under a new state air quality permit.


Some Lansing residents and two state environmental groups threatened to appeal that new permit
if GM didn’t agree to use better pollution controls. The two sides made their cases in the local
papers and eventually struck a deal.


Again, GM’s Steve Tomaszewski.


“We’ve come a long way, a long way, from where we started in the process. You know, we sit
down and we know more about people’s families other than just concentrating, on you know, the
industrial odor issues, which is great.”


General Motors agreed to join a new Air Quality Task Force. It’s made up of GM engineers,
environmental officials and people who live near the plants. GM also brought in an odor expert to
train the group to sniff out emissions from the plants’ paint shops. This “odor patrol” then files
reports to a new Web site.


Marci Alling is part of the group.


“They kind of calibrated our noses, that’s about the best way to describe it to kind of get us all
where we are more or less reporting the same levels of odor.”


Alling and her husband have lived near GM factories for 10 years. Often, whether they spend
time in their backyard depends on which way the wind blows. In certain weather conditions,
typically on hot, sticky days, a paint-like smell from the plants drifts through their neighborhood.
They’ve wondered whether the odors are making them sick.


State officials say the odors might be annoying, but recent studies found people who live near the
plants are not at a greater risk of cancer or other illnesses.


GM’s Steve Tomaszewski says the odor patrol will help the automaker better monitor emissions.


“We know we can’t be completely odor free. We strive to do our best. But this information, what
we’ll do is be able to go back and it’s more real time. You’re able to link it to the day and the time,
and we’re able to go back into the process to see what’s happening.”


But environmental groups say General Motors should be doing more to reduce pollution in the
first place, instead of tracking emissions after they become a problem.


James Clift of the Michigan Environmental Council says technology is available to make the
painting process cleaner. But he claims GM isn’t using it.


“If what you need is pollution control equipment and it’s not there, the odors may continue. We
might know better what they are, but if the permit doesn’t require them, it doesn’t matter. Now,
the department always has the ability to bring what they call an odor violation against General
Motors. In my mind, they’ve received lots of complaints over the years, but the DEQ has never
acted and actually issued a violation on odors.”


But the Michigan Department of Environmental Quality says it has issued odor violations against
General Motors. GM was ordered to raise its smokestacks in Lansing a couple of years ago
because of a violation. And GM says it recently spent 4-million-dollars on new painting
technology that greatly cuts down on pollution.


Now, General Motors is counting on its neighbors and their noses to help the company improve
air quality near its factories. GM says the project could lead to better pollution controls at plants
throughout the country, including more than 40 in the Great Lakes region.
