Turbines like these not only could help produce energy from a renewable and seemingly infinite resource, but could also create thousands of new jobs, according to the Union of Concerned Scientists.

A new report says a national renewable energy policy could create thousands of new
jobs in the Midwest. The Great Lakes Radio Consortium’s Erin Toner reports:
The report by the Union of Concerned Scientists urges Congress to adopt a policy
requiring 20 percent of the nation’s energy to be produced using renewable sources
by the year 2020. Those sources could be wind, solar, or geothermal energy. The report
says such a policy could create thousands of new jobs in manufacturing, construction and
maintenance.
Jeff Deyette is an energy analyst with the Union of Concerned Scientists. He says
rural communities – especially farmers – could be the biggest winners under the proposal.
“Farmers that were chosen to have wind power facilities sited on their land could get up
to as much as $4,000 per turbine to lease on their property.”
Deyette says a national renewable energy standard could save consumers nearly 50 billion
dollars by 2020. He says that’s because increased competition from renewables would help
lower the demand and the price of natural gas.

A new government report finds that twenty-four years after the federal government told the states to find ways to dispose of low-level radioactive waste, not a single site has been built. The Great Lakes Radio Consortium’s Lester Graham reports:

A new government report finds that 24 years after the federal government told the states
to find ways to dispose of low-level radioactive waste, not a single site has been built.
The Great Lakes Radio Consortium’s Lester Graham reports:
In 1980, the states became responsible for providing disposal sites for most of the low-
level radioactive waste. Low-level waste includes things such as clothing and tools
exposed to radiation in medicine, research and at nuclear power plants. But to date… not
one disposal facility has been built by a state. The investigative arm of Congress, the General
Accounting Office, reports that an older facility in South Carolina is the only
site still accepting waste… but it’s expected to restrict shipments by the middle of 2008.
The GAO’s Robin Nazzaro says it’s not a crisis situation yet…
“The bottom line fall back, though, is that sites can also store this waste at their facilities.
The Nuclear Regulatory Commission does allow for storage of waste as long as it’s safe
and secure.”
The GAO says a few states have plans to build facilities in the future… but nothing is
under construction right now.

The Bush Administration has been under a lot of pressure from environmentalists, hunting groups, and state agencies to do something about wetlands protection.

The Bush Administration has been under a lot of pressure from
environmentalists, hunting groups, and state agencies to do something about
wetlands protection. On Earth Day, President Bush responded by announcing a
new initiative that he says will take wetlands protection to a higher level.
The Great Lakes Radio Consortium’s Mark Brush takes a closer look at the
President’s latest proposal:
In the last thirty years, urban sprawl and farming have destroyed millions of
acres of wetlands. Because of that, the past two Presidents called for a
policy of “no net loss of wetlands.” The current Bush administration says it also
supports that goal. And says it wants to go a step further.
On Earth Day, the President unveiled his latest plan to protect and restore
wetlands.
“The old policy of wetlands was to limit the loss of wetlands. Today, I’m going to
announce a new policy and a new goal for our country: instead of just
limiting our losses, we will expand the wetlands of America.”
(Applause – fade under)
The Bush administration says its policy will restore, improve, and protect a
total of three million acres of wetlands in the next five years. In his speech, the
President gave a general outline of the plan, saying he’s going to increase support for a
number of programs already in place.
Ben Grumbles is an Assistant Administrator at the Environmental Protection
Agency. He heads up the water and wetlands programs for the EPA. He says
the President has called on many agencies to implement the new plan:
“The heart of the President’s new goal and commitment is to use
collaborative conservation-based programs to gain three million acres of
wetlands and to do so through USDA, Interior, Fish and Wildlife Service, conservation programs and
partnerships with the private sector.”
While environmentalists approve parts of President Bush’s new plan, many of
them say it’s the wrong first step to take. Julie Sibbing is a wetlands
policy specialist with the National Wildlife Federation.
“Although it’s a great thing that they’re going to get a million acres of
wetlands restored, and a million acres enhanced, and a million acres
protected, it’s only a drop in the bucket compared to what’s currently at
risk due to their policies on protecting wetlands under the Clean Water
Act.”
And that’s the main criticism – environmentalists and some hunters say the
Administration is not doing its job in enforcing current federal laws. Laws that protect
rivers, lakes, and wetlands – and worse – they say the administration has
actively weakened laws that protect millions of acres of smaller, isolated
wetlands. These critics see this latest announcement by the Bush Administration
as an attempt to shore up its dismal record on the environment in general…
and on wetlands in particular.
The National Wildlife Federation’s Julie Sibbing says the Administration
would make better use of taxpayers’ money by reviewing some of its policies
and protecting wetlands that already exist:
“It’s just too hard to build new wetlands for us to ignore protecting what’s
there right now. We love the programs that restore former wetlands, but the
most important thing is to try to protect those wetlands that we still
have.”
Officials in the Bush Administration say they are serious about enforcing
the law. And they say they are protecting wetlands. They say they’re just
taking a different approach.
In his speech, President Bush said good conservation will
happen when people don’t just rely on the government to be the solution to
the problem, saying more people should look to private sector land trusts
and voluntary efforts by landowners to get the job done.

Every summer, thousands of people wander through swamps and ditches in search of frogs.
they’re frogwatchers – volunteers across North America, who help
scientists track the health and movement of amphibians. The Great Lakes Radio Consortium’s
Karen Kelly caught up with one group and found they’re no longer just watching frogs, but
rescuing them:
(sound of frog, “I think this one’s talking now…”)
11-year-old Tyler Degroot shows off two bullfrogs in the plastic
terrarium he’s carrying. He struggles to keep the lid on as they try to escape.
He’s spent all morning combing for frogs in this swampy ditch on
Petrie Island. Not far from Ottawa, Canada’s capital.
It’s pouring rain. But he and his friends have no time for jackets or umbrellas. They run from log
to log dipping their nets in the water.
(“Holy smokes! Look at them all!”)
It might sound like fun, but they’re here on serious business.
The bulldozers in the distance are a constant reminder. Soon, this ditch – the frogs’ home – will be
turned into a parking lot.
11-year-old Ingrid Weinhold says they’re here to save as many
frogs as they can.
“We want to make sure the frogs stay on Petrie Island
and we want to make sure that people can see frogs later and so
that they don’t all die when the ditch gets filled with sand.”
Weinhold is a member of the Amphibian Conservation Club. It’s a group of homeschoolers who
meet once a month to study and discuss amphibians. They started visiting Petrie Island last year
to conduct frog watches.
It’s part of an annual census of frogs led by Environment Canada,
a government agency. The students count the number and species of frogs to find out how
many are in a given area. And that’s when they discovered that some of the resident
amphibians were in danger.
(“I just saw a whole bunch of frogs over here, okay? They went in all different directions.”)
11-year-old Gabrielle Felio is the club’s founder.
She hesitates to leave the ditch until every frog has been picked
up.
As she talks about them, her eyes look worried behind her
rain-splattered glasses.
“It’s just that they help the environment a lot. That’s
probably why we like them a lot and we want to help them. Because
it’s going to help the area and it’s going to help a lot of other
animals if we help the frogs.”
(walking)
With their terrariums full, the frogwatchers hike through the woods to a pond that they’ve
adopted. They’ve saved more than 30 frogs today. There are green frogs, bull frogs and leopard
frogs.
When they reach the pond, the rescuers open their terrariums.
(“There they go!”)
Some reach in and pull the frogs out one by one. Others just tip the terrariums upside down.
(“Woo! He’s a slippery one. I’ll get him. You did a cannonball!”)
Tyler DeGroot watches his bullfrog kick away from the shore.
He looks satisfied.
“I feel good…I think the frogs feel good, too, cause
they’ll probably have a nice little happy pond that’s not polluted
so they can just swim around and have fun.”
Each student carries a notebook to keep track of how many frogs
they moved from the ditch to the pond. Then, at the end of the summer, the group will compile
all their observations. They’ll send them to Environment Canada’s Frogwatch.
Elizabeth Kilvert is the director of the program. She says the reports from these amateur
scientists are invaluable.
“When we have people out there observing in their backyards
at different locations, we’re getting really good geographical
coverage that Environment Canada could never provide by going and
working out in the fields.”
Kilvert says it’s important to track frogs. That’s because they’re sensitive to changes in the
environment. And researchers see them as an early warning system.
Frogwatcher Ingrid Weinhold says she’s happy to help.
“I feel pretty good cause then they can figure out stuff with
the information… like if there’s too much pollution in one spot
and if the frogs have too many legs or something they can figure
out if there’s something wrong with the water.”
Before long, the frogwatchers are catching frogs again – in the
same pond where they just released them.
(“Let me see him!”)
This time, it’s just for fun.
Soon, they’ll head back to a classroom to compare notes… and make plans for their next rescue
effort – before the bulldozers move in.

The Amphibian Conservation Club meets at Petrie Island, outside of Ottawa,
Ontario, once a month. These young homeschoolers usually come to the island to study
frogs. But they recently discovered one of their favorite ponds is going to be
turned into a parking lot.
So, the kids have embarked on a rescue mission – moving as many frogs as
they can. 11-year-old Frank Ogilvie says they’re motivated by their love of
amphibians.
“I really, really, really like frogs. Yes I do. And I think that
they’re a great habitat indicator and that they are one of my favorite
animals.”
The group is inviting family and friends to join them in a last minute
blitz to save the animals before the bulldozers cover up the frogs’ home.

A Canadian firm is gearing up to produce a cloth–like solar panel that will cost less than current technologies. The Great Lakes Radio Consortium’s Lester Graham reports:

A Canadian firm is gearing up to produce a cloth–like solar panel that will cost less than current
technologies. The Great Lakes Radio Consortium’s Lester Graham reports:
This is a photo-voltaic solar panel, but instead of being a sheet of silicon on glass, it’s tiny beads
of silicon between layers of aluminum foil and sealed in a plastic sheeting. It’s strong, light
weight, and flexible.
Ron Jutras is a company officer with Spheral Solar in Cambridge, Ontario:
“The primary difference between this particular solar panel and others that people are used to seeing
maybe on highway signs or potentially on buildings, is the fact that it is a pliable system, meaning
that it can be bent and wrapped around products.”
So the solar panels can be put on facades of buildings or draped over a roof. It also will come
in different colors, giving architects some flexibility. Because it uses much less silicon than
current technology, the price is expected to be quite a bit lower. The first commercial shipments of
the flexible solar panels are expected next year.

To the environmentalist, “green” refers to something environmentally friendly. When manufacturers refer to green, they usually mean money. But with an increase in the demand for environmentally sound buildings, manufacturers have the opportunity to combine the two definitions. For those who see the possibility, retooling to meet the demand for green construction could mean a large payoff in a burgeoning industry. The Great Lakes Radio Consortium’s Shula Neuman reports:

To the environmentalist, “green” refers to something environmentally friendly. When
manufacturers refer to green, they usually mean money. But with an increase in the demand for
environmentally sound buildings, manufacturers have the opportunity to combine the two
definitions. For those who see the possibility, retooling to meet the demand for green
construction could mean a large payoff in a burgeoning industry. The Great Lakes Radio
Consortium’s Shula Neuman filed this report:
There’s an 86-year old abandoned building in a Cleveland neighborhood that was left for dead a
few decades ago. It’s a shame because inside the building are 26-foot high ceilings with ornate
molding, original Tennessee marble walls and wood trim. But recently, the building, which was
once the Cleveland Trust Bank, was identified by a coalition of local environmental groups as the
ideal spot for their offices. The Cleveland Green Building Coalition spearheaded the task of
converting the old bank building into the new Environmental Center. Executive director Sadhu
Johnston explains, the project is not your average renovation.
“What we’re really trying to do is to demonstrate to people that you can do green while
preserving and that’s often they are seen to butt heads and this project is showing that the two
movements have a lot in common.”
While touring the mostly finished building, Johnston points out seemingly endless
environmentally friendly features. First, there’s a radiant floor heating and cooling system. Then
there are the geothermal wells under the parking lot. They use insulation made from recycled
paper and cardboard. And the roof is divided into three sections: one part has traditional black
tar, another has a white reflective coating and the third segment is a living roof, which looks like
a garden.
Johnston says the layout is meant to demonstrate a more than 100-degree temperature variation
between the three surfaces. All of the different materials and methods used to construct the
Environmental Center, could signal a forward thinking manufacturer to see financial reward from
the burgeoning interest in green buildings. After all, green buildings tend to save money.
The Environmental Center is 67-percent more energy efficient than required by code. In fiscal
terms, that adds up to a half-million dollar savings over 20 years. This might make you wonder
why more people aren’t building green. Actually, according to U.S. Green Building Council
president and CEO Christine Ervin, interest in green construction has been increasing over the
past decade. Since the group established green certification standards three years ago, nearly 700
projects have registered to meet certification. And, Ervin adds, the increase in interest is not
exclusive to tree-huggers
“The diversity of the kinds of projects also is telling us that this is a serious trend that is moving
into the mainstream market. We have projects that are registered firehouses, small schools, FAA
stations. All the way up to manufacturing plants and convention centers.”
Several cities and government agencies are already mandating green construction on new
buildings, including the city of Portland, the General Services Administration and the U.S. Army.
David Goldstein is with the Natural Resources Defense Council and environmental group in San
Francisco. He says there’s a movement afoot to establish national incentives to build green. In
other words, the time is ripe for the construction industry to get with the green program.
“From the point of view of the manufacturers of the equipment and supplies, and of the expert
building designers who put all these things together, once these policies for green buildings are
there, that’s a new market opportunity for them. So it is in their interest to promote these kinds of
policies.”
Goldstein adds green regulations also have a coincidental social benefit. With 35-percent of
pollution coming from the electricity and gas buildings use, requiring green buildings is as much
a public health issue as it is an economic one.
Some manufacturers in the great lakes region have caught on to the possibilities. The Cleveland
Based Garland Company manufactures and installs roofing systems all over the country and is
responsible for the Environmental Center’s roof—its first in-town green job. Garland
incorporates recycled materials into about 80 percent of its products. Nathan Schaus, project
manager at Garland, says about 15 percent of their business comes from their green product line.
Schaus says the market for green materials will continue to grow, especially with manufacturers
pushing its benefits.
“It’s a two-fold education. You need to educate the buyer, the end user that what they’re buying
is a building solution for the long term. So the initial investment, you have to explain that cost
over its life cycle. With the incentives, it’s changing the mindsets of the people that regulate
government and electricity today.”
Government regulators may work even faster on establishing incentives when they see the
increase in demand for residential green building on top of the commercial market. According to
the National Association of Homebuilders, about 13,000 green homes were built last year – a
huge increase over any single year before that. If demand continues to increase at such a rapid
pace, those business that go green now may be making plenty of green in the future.

The cost of building a home is soaring. Materials are expensive, and skilled labor is scarce. The high costs are contributing to a crisis in affordable housing, in the Great Lakes region and around the country. A new technology from Japan could be part of the solution.

The cost of building a home is soaring. Materials are expensive, and skilled labor is scarce. The high costs are contributing to a crisis in affordable housing, in the Great Lakes region and around the country. A new technology from Japan could be part of the solution. The structural pieces of a custom-designed home are cut out in a factory, using wood manufactured from small-diameter trees. Even unskilled workers can assemble the house on site in about a day. The Great Lakes Radio Consortium’s Stephanie Hemphill watched a home going up:
Five East 5th Street is a narrow lot a few blocks above downtown in Duluth, Minnesota. A new basement juts out of a hole in the hillside. From the front yard, there’s a spectacular view of Lake Superior.
Most of the houses in this neighborhood are at least 80 years old. They’re small houses built for working families. A few vacant lots show where dilapidated houses were torn down.
One day last month, the new house arrived on a truck.
(sound of Martin listing parts)
Santos Martin works for Kato Sangyo, the Japanese company that invented this system of homebuilding. He calls out the part numbers as half a dozen apprentice carpenters carry the pieces off the truck. Soon the lot is covered with stacks of house parts – corner posts sixteen feet long, and insulated wall panels in various sizes, as big as 4 feet by 9 feet.
Then the workers start to put the pieces together.
“Every component is numbered, every component has a specific place and an internal metal connector that allows you to put it together like you would a TV entertainment center or a bed frame.”
James Brew is the architect who had the dream for this house.
Brew was fascinated by Japanese culture since he was a kid. He’s traveled to Japan several times, and hosted exchange students in his home. Two years ago he learned about a Japanese company that created a home-building system that allows even inexperienced workers to frame up a custom-designed house in a day,
“People who haven’t built with this system, there they are pounding together a beam and a post and with a little bit of weather cooperation they will probably have this entire house framed today.”
The beams are made of laminated strand lumber. Instead of cutting big trees into 2 by 4s, laminated strand lumber uses smaller trees and even waste wood, glued together like plywood.
This type of “engineered wood” is being used more and more in homebuilding. What sets the Kato Sangyo system apart is the way the framing pieces are locked together with metal connectors.
The beams for this house are four inches square, and either eight or sixteen feet long. At the end of each beam there’s a slot for a metal connector. It’s like a large hinge. Workers slide one end of the hinge into the beam, and match the other end to a slot in the floor.
Then they raise the beam until it’s standing upright. They slide the insulated wall panels into the spaces between the beams. Everything is supposed to fit precisely because it was cut to order in a factory. Once the framing is up, workers will add siding, and the house will look just like the other ones on the block.
The assembly is mostly a matter of matching the right parts. So it’s an ideal project for people who are just learning how to build. Lisa Lyons is one of the crew members. She and her co-workers are part of a job training program for battered women. After a year of learning standard construction techniques, Lyons says this job is fun.
“Before it’s a lot of framing, a lot of measuring, and this here you just pound in some pegs and stand it up and it’s just like lego blocks, it’s really cool.”
The Japanese system offers not only speedy construction, but the potential for more affordable housing. The parts for this house were made at a factory in Minnesota. They were cut by hand, which took a couple of days. Architect James Brew says they could be cut in a couple of hours in a fully automated factory.
As the house takes shape, visitors stop by to watch. They include businesses thinking about the Japanese system as a possible new industry for Minnesota. James Brew says it would cost about a million dollars to buy the equipment to make the house parts. And he’s talked with a lot of lumber and construction firms that are intrigued with the idea.
“So there’s many interests in the system and the idea, the technology, but it’s again chicken and egg. Which is first, sales without a factory, or factory with no sales, or together. It’s very difficult.”
Brew is hoping the house in Duluth will provide the demo that will spur some business to decide there’s a future for the Japanese system in the United States. For the Great Lakes Radio Consortium, I’m Stephanie Hemphill in Duluth.
Steel has once again become a big issue in U.S. trade policy. Many steel companies around the Midwest are worried about ‘steel dumping’ and are urging President Bush to support new tariffs and quotas on imported steel. But some steel users say the Bush Administration should back off. How the President handles the issue could affect both jobs and the environment in the region.

Steel has once again become a big issue in United States trade policy. Many steel companies around the Midwest are worried about steel dumping and are urging President Bush to support new tariffs and quotas on imported steel. But some steel users say the Bush administration should back off. How the president handles the issue could affect both jobs and the environment in the Great Lakes region. The Great Lakes Radio Consortium’s Chuck Quirmbach reports.
The amount of commonly used types of foreign steel coming into the United States has risen about a third over the last five years, and a federal trade panel ruled recently that much of that imported steel is being sold here at a price lower than what it cost to make it and ship it here. That’s a practice called dumping. The trade panel found that such dumping poses a serious threat to domestic steel makers. So the panel says President Bush should slap tariffs on many product lines of foreign-made steel to raise the prices of the imports. But that’s not such a hot idea to some other industries, which use plenty of foreign steel.
(furnace/factory ambient sound)
Here at the Engel Tool and Forge Company in Milwaukee…this second-generation family business now uses about 600 tons a year of steel imported from countries like Brazil and Sweden. In the warm and grimy forging area, workers use a robot to move five foot long steel bars that have been heated to 2100 degrees Fahrenheit. Owner chuck Engel watches the orange and white-hot bars enter a machine
“That’s a preforming press …a hydraulic press that preforms the metal. It’s removed from there and moved into a finished form that we gain our finished desired shape.” (WHAM noise)
The bars are scrunched into wheel axles that’ll be shipped to heavy equipment makers in the mining or construction industries. Engel says his company is doing all right during the recession. So he’s says he strongly opposed to the president possibly tinkering with that success by slapping higher tariffs on imported steel.
“I am sure there is a certain amount of unfairness on both sides of the fence but I believe that competition should be what sorts this problem out rather than the government.”
Engel contends domestic steel makers got quote- fat and sassy — over the last twenty years…and he says mergers, downsizing and other changes now taking place among domestic manufacturers will help them compete in the world steel market. Engel says if steel tariffs do go up…he’d have to pass along the price hikes. But other players are urging President Bush to approve higher steel tariffs. The United Steelworkers of America hopes the president even goes beyond what the trade panel recommends. Some environmentalists are also quietly supporting the domestic steel industry. That’s even though green groups have a track record of battling steel manufacturers. Cameron Davis of the Chicago-based lake Michigan federation acknowledges big steel has a dirty history in the area.
“Well traditionally, the steel industry especially in northwest Indiana has been responsible for a fair amount of pollution in the Great Lakes…and that’s air-based pollution, water based pollution, land based pollution across the board.”
But lately environmentalists have been trying to forge alliances with unions like the steelworkers. And Davis notes that environmental lawsuits and other changes have gotten domestic steel makers to start cleaning up their act in recent years. He says if nothing is done to slow the rise in steel imports that could make the United States environment worse. Davis cites the aquatic nuisance species that tag along in the ballast water of foreign ships…including presumably, the ships that bring in foreign steel.
“Without some help in protecting the GL steel industry, we’ll see more and more foreign steel coming into the country. And with that foreign steel probably more aquatic nuisance species that will do more damage not only to the Great Lakes but to rest of country.”
United States flagged Great Lakes shipping companies that haul iron ore from Minnesota and northern Michigan are also siding with the domestic steel makers. George Ryan is president of the Lake Carriers Association. He says if the domestic steel industry keeps getting hurt by foreign imports…there might be some local improvements like less air pollution emitted over Gary or Cleveland, but Ryan says, what about the rest of the globe.
“For anyone who has seen photographs from outer space, we have one world that moves the air around to all parts of the world we can’t really say we condone dirty air in Brazil and in China and okay to do it there cause we’re protecting our air in the United States.”
Ryan is a member of the Great Lakes Commission…which is urging the president and congress to boost steel exports and reduce unfair competition from abroad. Commissioners do the bidding of eight Great Lakes governors…most of whom are republicans like George W. Bush. If the president does not do more to protect United States steel makers and jobs that could be an issue in the gubernatorial and congressional elections next November. Mr. Bush has to announce his plans on steel tariffs and quotas by mid-February. For the Great Lakes Radio Consortium this is Chuck Quirmbach in Milwaukee.

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.

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.
