In the last few years, researchers have discovered links between the exhaust fumes from diesel
buses and rising asthma rates in children. Scientists and environmentalists have called on the
government to crack down on diesel emissions from school buses. But as parents learn about the
risk to their kids, they’re not waiting around for the government. They’re doing something right
now to help reduce their kids’ exposure to the exhaust fumes. The Great Lakes Radio
Consortium’s Erika Johnson reports:


(sound of diesel school buses idling)


At the end of the school day, buses sit, often idling their engines, waiting for the dismissal bell
and the kids to get on. Not every school district uses diesel school buses, but many do.
And when their engines are left running, they constantly spew out a sooty diesel exhaust that’s
hard to avoid.


(sound of kids)


“It’s an unnatural smell, kind of like plastic…”
“Smells like a car…”
“…Plastic and gas.”
“It smells like gasoline…”
“…But it stinks…”


Kids don’t like the smell of the exhaust, and parents are finding that the diesel fumes are doing
more than just creating a nasty stench – it’s putting their kids’ health at risk.


Sally Cole-Misch says for a long time, she never thought much about it. The yellow buses were
just a part of the daily routine:


“Well, you know, you never think that when you take your child and put them on the bus and
wave goodbye, you think, oh, they’re safe, no problem. And I started noticing the buses at the
schools, how they did idle, and started thinking, this is important, this is something really we need
to be focusing on.”


Cole-Misch was concerned about her kid’s exposure to the exhaust fumes. But rather than simply
taking her kids off the school bus, she decided she wanted to do something for all of the children
in her community. So, she and other concerned parents began meeting with a local
environmental group. They came to the conclusion that the best way to get rid of the diesel
fumes was for bus drivers to turn off their engines while waiting for the kids. As part of their
anti-idling campaign, they’re pushing their school district in Bloomfield, Michigan, to have bus
engines turned off until the buses are loaded up and ready to leave for their routes. During cold
weather, bus drivers can keep warm inside the schools, and then heat up the buses as soon as the
kids get on.


Cole-Misch says as parents learn about the issue, they’re getting involved in the anti-idling
campaign:


“I think this is the type of issue that the solution is so easy, in that in most school districts all you
have to do is give the parents the information, and I think it’s something that they can easily act
on.”

And the Eastern Michigan Environmental Action Counsel, also known as EMEAC, is doing just
that. The group is providing information to parents and is promoting the idea to local school
board officials.


Libby Harris is Staff Attorney for EMEAC. She says getting the parents involved has made their
campaign successful:


“Without the parents there, the school officials are going to respond that it’s a good idea, but they
are faced with a tremendous number of requests for programs. Having the parents there is a
direct statement. ‘This is a health issue, I’m concerned about it, and I really want you to take this
seriously and to take steps.'”


Concern over the health effects of diesel exhaust stems from the rising asthma rates reported
among children. The Centers for Disease Control estimate that nearly 5 million children
nationwide have the disease. Although no one knows exactly what causes asthma, scientists say
many of its triggers are found in the air we breathe. Recent air toxics studies have shown that
particulate matter, the soot released from diesel trucks and buses, is a leading air pollutant.


Dr. Thomas Robbins is a Professor at the University of Michigan’s School of Public Health:


“It is quite possible that a substantial fraction of the total diesel exposure, even total particulate
exposure, a child is going to experience during the day could be associated with school buses, and
so it’s potentially quite an important problem.”


And the government is also doing something about this growing public health problem, and has
tried several demonstration projects. EPA’s Clean School Bus U.S.A. Program is supporting
sixteen school districts nationwide with a small grant to participate in projects, such as using
cleaner diesel fuels, and retrofitting school buses with pollution control devices. The ultimate
goal is that these projects will become models for states to follow:


Jeff Holmstead is head of EPA’s National Air Pollution Control Program. Holmstead says all
diesel engines are to be replaced or retrofitted by the year 2010. But he says even with the stricter
standards, it’ll take some time to replace the older buses with cleaner ones:


“One of the reasons for this program is because diesel engines have such a long lifetime, it will
take many years, probably out to 2020 and 2030 for the newer engines to replace the existing
fleet. And that will take a little time and we’re just trying to expedite that process, and make it
happen as quickly as we can.”


But the problem now is that there isn’t enough funding to support programs like this in schools
nationwide. That’s why many schools and environmental groups, such as EMEAC, have turned
to anti-idling campaigns. They’re working with what they do have – and that’s the support of
their local community – until they have the funding for larger scale programs. Anti-idling
campaigns are becoming a growing trend in schools nationwide, and some states such as
Minnesota and Connecticut already have anti-idling laws in place.


Libby Harris of EMEAC says the energy behind their campaign starts with the local community:


“Once EPA announced its Clean School Bus U.S.A. Program, we saw that the momentum was
there, that by working with other organizations and inviting parents and members of PTO’s and
school officials, we had a good chance of making a difference and reducing the exposure that kids
have to school bus exhaust. And to reduce the amount of idling is something that can be done
without any cost.”


Not only realizing that school bus diesel exhaust is putting their kids health at risk, but that they
can do something even without any funding at all, more parents such as Cole-Misch have decided
not to wait around for diesel engine phase-outs or government programs. Instead, they’re pushing
their school districts to start doing something right now about the diesel fumes their kids are
breathing. And they feel progress starts when the buses are turned off.

Unions Sue Over Factory Air Quality

The United Auto Workers and United Steelworkers of America have filed a lawsuit against the U.S. Labor Department. The unions want the federal department to set clean air standards inside factories. The Great Lakes Radio Consortium’s Jerome Vaughn has details:

The United Auto Workers and United Steelworkers of America have filed a
lawsuit against the U.S. Labor Department. The unions want the federal
department to set clean air standards inside factories. The Great Lakes
Radio Consortium’s Jerome Vaughn has details:


The Unions want a federal appeals court in Philadelphia to order the Labor
Department’s Occupational Safety and Health Administration otherwise known
as OSHA to issue new indoor clean air standards. The regulations would
reduce exposure to toxic metal working fluids used in building
automobiles, aircraft, and other products.


The UAW and the Steelworkers union say the current regulations instituted
in 1971 just aren’t stringent enough. The U.S. Centers for Disease Control
says there’s substantial evidence that the fluids can cause cancer of the
larynx, pancreas, skin and bladder.


The unions originally petitioned the Labor Department to change its
regulations back in 1993 but the agency has not explained its reasons for
refusing to make the changes.


The Labor Department says its highest priority is the health and well-being
of U.S. workers.

‘Good’ Air Days Bad for Asthmatic Kids

A new study indicates even when the EPA’s Air Quality Index is green, indicating
‘good’ air
quality, the pollution in the air could trigger asthma problems for kids. The Great
Lakes Radio
Consortium’s Lester Graham reports:


This study by Yale University looked at children who had asthma and measured the
effects of air
pollution such as ozone.


Janneane Gent led the study.


“And what we found was that among the children who had the more severe asthma, for
every 50
parts per billion increase in the level of ozone, the likelihood that they would
wheeze was
increased by 35 percent. And the chance that they would experience chest tightness
was
increased by 47 percent.”


That 50 parts per billion of ozone is within the range that’s considered ‘good’ air
quality by the
Environmental Protection Agency. Gent says that means even on ‘yellow’ or
‘moderate’ air
quality days parents should make sure kids with asthma are kept indoors and their
activity levels
kept low to avoid triggering asthma attacks.

On March 31st, the U.S. Environmental Protection Agency will be holding public
hearings across the country about changes to Clean Air Act regulations, called New
Source Review. The Great Lakes Radio Consortium’s Annie MacDowell has more:


The proposed changes to the New Source Review would relax standards for pollution
controls on power plants that are more than 25 years old.


Environmentalists worry the new standards could allow old power plants to pollute more.


The EPA will hold forums in Albany, N.Y.; Dallas, Texas; Romulus, Michigan; Salt
Lake City, Utah; and the EPA’s Research Triangle Park headquarters in North Carolina.


Bill Harnett is the Director of the Air Permitting Division of the U.S. EPA. He says the
meetings will give the public a chance to ask questions and make comments about
changes to New Source Review.


“It gives them more of a direct feed into the agency and the process, and it’s
something we always do on our rules is offer this kind of opportunity. And on
major rules like the one we’re doing, we always offer it in multiple places in the
country.”


Harnett says he expects a good turn-out, and the hearings could last all day.


After all public comments have been received, the EPA will review them and
decide whether to make the proposed changes.

Emissions Trading for Telecommuters

Companies who fear that their greenhouse gas emissions may soon be regulated are being
offered a new alternative. A Virginia-based firm has created an emissions trading system
that will capitalize on telecommuting. The Great Lakes Radio Consortium’s Karen Kelly
reports:


The company is called “Teletrips.” And it’s created a system in which industries that
need to reduce their emissions can buy credits from businesses with large numbers of
telecommuters.


Teletrips president Mary Beatty says the trading system would force polluters to buy
credits to offset the amount they pollute. They’d buy the credits from companies who
keep their employees off the road.


“We felt like if you could find an incentive that would motivate companies to set up
(programs) trip reduction programs and (be able to quantify that) and give them some real
financial benefit back for creating those programs, that was much better than mandating
an approach.”


The company’s software converts the number of trips saved by working at home into the
amount of emissions averted.


It’s currently being pilot tested in five U.S. cities.

A new study shows African Americans are disproportionately affected by power plant pollution. The study finds most African Americans are concentrated in urban areas, closer to power plants. As the Great Lakes Radio Consortium’s Annie MacDowell reports, health problems in the community such as asthma have been tied to air pollution:


The study shows blacks are hospitalized for asthma attacks at more than three times the rate of whites, and their death rate from asthma is twice that of whites.


Brian Urbaszewski with the American Lung Association says there’s a direct link between air pollution and asthma, especially within the black community.


“African Americans just tend to have a higher rate of asthma, so you have the people who are more likely to be sick in an area where the air is more likely to trigger an asthma attack.”


In one Great Lakes state, 90 percent of blacks live in counties with air pollution levels that exceed federal health standards.


African-American babies are in greater danger of sudden infant death syndrome and respiratory mortality because they live in more polluted areas.


The groups that put out the study want stricter laws to reduce emissions from coal-burning power plants.

Farming in Age of Global Warming

For years, scientists have been studying what will happen to
our environment in the age of global warming. A recently
released report draws some conclusions about what may
happen in the farm fields. The Great Lakes Radio Consortium’s
Bill Cohen reports:


More carbon dioxide in the air will bring larger crop yields, says
plant ecologist Peter Curtis of Ohio State University. He and other
OSU scientists have just finished reviewing 159 studies from the past
20 years on global warming. Their conclusion – by the end of this
century, some plants will produce more grain.


“Corn, for example, about 5%, wheat we’re lookin’ at about 15%, barley
a little bit more – maybe 18%, soybeans at around 20%, and then rice
all the way up around 40%.”


More food, says Curtis, but it might be less nutritious. That’s the
downside his study is predicting if global warming continues – the
crops will contain less nitrogen and that may mean less protein for the
humans, cows, and pigs that eat it.

Reining in Diesel Exhaust

You see them every time you pass a construction site. Big machines belching thick diesel smoke. The smoke isn’t just annoying. It causes major health and environmental problems. Now, after years of dealing with other issues, the EPA is taking on this major source of uncontrolled pollution: emissions from farm and construction equipment. The Great Lakes Radio Consortium’s Julie Halpert looks at the challenges EPA faces in this far-reaching regulatory effort.


Emissions from diesel engines create problems for both the environment and people’s health. Diesels release nitrogen oxides, which are a factor in acid rain and smog. They also spew very fine particulates that can lodge deep in the lung when inhaled. And that causes respiratory problems.


Controlling these emissions is no easy task. That’s because most diesel engines still burn fuel containing high amounts of sulfur. The sulfur clogs up existing pollution control devices. And that makes it a lot tougher to come up with ways to reduce emissions. But Christopher Grundler, deputy director of the EPA’s Office of Transportation and Air Quality in Ann Arbor, Michigan, says its an important challenge.


“In the year 2007 we estimate that off road or non-road emissions will make up over 40% of the air pollution from mobile sources or transportation sources, so it’s a big deal.”


In tackling air pollution, EPA’s first job was to clean up gasoline car emissions. Now its moving onto diesels. The agency’s first challenge came when they issued a rule for highway trucks last year. That plan drops sulfur content in diesel fuel from 500 parts per million to 15 parts per million. It also reduces overall diesel emissions by 90% by the year 2007. The EPA now wants to use this rule as a model for farm and construction equipment as well. But the agency is likely to face opposition from refiners, who are fighting the on road rule. Jim Williams is with the American Petroleum Institute.


“We feel that the ability of the refining industry to make sufficient volumes of 15 ppm in the timeframe that EPA wants us to is highly questionable, whether we can do that. We’ve done some studies that show there will be supply shortfalls with the 15-ppm limit.”


Williams is pushing to phase in the requirement over a longer period. He says that would give refiners more time to produce the necessary quantities of low sulfur fuel. Until then, refiners also want to continue providing high sulfur fuel.


But Engine Manufacturers don’t like that idea. They’ve agreed to support tough standards only if the switchover to low sulfur fuel happens quickly. Jed Mandel runs the Engine Manufacturers Association. He’s worried that if cheaper, low sulfur fuel remains abundant; users could continue relying on the dirtier fuel.


“If there are dual fuels available — if there’s cleaner fuel on the marketplace for some time, as well as higher sulfur dirtier fuel, and there’s a price differential in that fuel, there will be a disincentive for users to buy the cleanest engines.”


Mandel says that could cause a delay in purchasing these engines for several years.


Like Mandel, Jason Grumet, executive director of the Northeast States for Coordinated Air Use Management, also wants tight standards. Northeast states, plagued with acid rain and smog caused largely by these diesels, are pushing the EPA to develop the tightest standards possible to meet clean air goals and also to better protect equipment operators.


“The particles from diesel emissions can lodge very deep within the human lung and we know that these particles are carcinogens, so for folks who work with construction equipment every day or on construction sites, for people who farm or plow fields for several hours a day, we think that the emissions of diesel pollutants cause a very substantial and real threat to their health.”


(sound of tractor)


Herb Smith isn’t worried about his health. Smith hops off his tractor and stands on the land that his family has farmed in Ida Township, Michigan since 1865. Despite years of inhaling diesel fumes, Smith said he’s in perfect physical condition. Though he supports regulations to control diesel emissions, he’s worried that the EPA will place undue hardship on farmers.


“I am concerned about fuel costs because our margin in farming is very slim and anything we add to fuel costs, we have to absorb it.”


Smith fears that some of the smaller farmers may not be able to bear higher fuel and engine costs and could go out of business.


Despite the many different viewpoints on the issue, EPA’s Grundler is confident that his agency can develop a rule that will bring tremendous public health benefits at a reasonable cost.


“We’ve shown we can do it for cars and SUVs. We’ve shown it can be done for heavy duty on highway engines. I’m absolutely certain it can be done for these sorts of engines as well.”


The agency expects to issue a technical report outlining emission control options by the end of the year. A proposal is due by the middle of next year. For The Great Lakes Radio Consortium, I’m Julie Halpert.
