The historic Coast Guard icebreaker Mackinaw has docked for the final
time. The vessel is scheduled to be decommissioned at the beginning of
June, after more than six decades of service on the Great Lakes. The
GLRC’s Sarah Hulett visited the ship on its farewell tour of the lakes, and
has this report:


I’m on the bridge of the 290-foot icebreaker, and I’m just in time for the
daily test of the vessel’s alarms and whistles.


(Sound of bell)


After 62 years, they’re still working.


(Sound of alarm)


The Mackinaw was built in Toledo, during World War Two – when
demand for raw materials from the Great Lakes region exploded.


The icebreaker extended the shipping season through the winter, and
helped make sure iron ore and other cargo could get to the industrial
cities at the center of the war effort.


Today, Pat Pietrolungo and his 80 fellow crewmembers are still keeping
the shipping lanes cleared for commercial transport. They can spend up
to two weeks at a time on the ship, cutting ice during the winter months.


But cruising Lake Superior in the dead of winter can get spooky on those
long, cold winter nights.


Pietrolungo says there are some crew members who think there’s a ghost
on board the Mackinaw.


“Certain little weird things happen. Lights will flicker that shouldn’t,
doors will shut, some of the wheels on the scuttle will turn. I guess it
was a former crew member that died on board.”


But that ghost will have a lot less company soon, when the crew moves
to the Mackinaw’s smaller, more efficient replacement this summer.


The old ship isn’t flexible enough to serve other purposes for the Coast
Guard. And Pietrolungo – the Mackinaw’s machinery technician – says
finding parts for the vessel’s huge diesel engines is getting more difficult
by the year.


“It’s more or less along the lines of a locomotive engine. So you’ve got
to go start searching train museums, more or less, to find the big parts if
we needed them.”


A non-profit group based in Cheboygan, Michigan wants to make the
Mackinaw itself a museum.


Hugh O’Connor and his two young children were the first in line to
board the vessel when it docked in Detroit during its farewell tour. He
says he’ll be sad to see the Mackinaw decommissioned, but he says he
would visit the ship as a museum. Like a lot of boys who grew up along
the lakes, O’Connor says he and his friends knew the names of all the
freighters, and looked forward to catching a glimpse of the Mackinaw.


“We always used to ice fish in the winter, and I remember from our ice
shanty you’d get out and see it going by, breaking ice on Lake Saint
Clair for the freighters. That was when they were trying to run the boats
year-round. I don’t think they do that much anymore though. That was
pretty cool. Back then it was all white, though. Painted all white.”


The Mackinaw’s hull – painted red since 1998 – powered through thick
sheets of Great Lakes ice for the last time this past winter.

Revving Up Sales of Cleaner Diesel Cars

When you think of diesel engines, you might think of big, noisy, stinky trucks. But that’s changing. And a domestic automaker has plans to bring a cleaner, higher performing diesel engine to passenger cars. The company insists: it’s not your father’s diesel. The GLRC’s Julie Halpert has the story:

When you think diesel engines, you might think of big, noisy, stinky
trucks, but that’s changing and a domestic automaker has plans to bring a
cleaner, higher performing diesel engine to passenger cars. The
company insists: it’s not your father’s diesel. The GLRC’s Julie Halpert
has the story:


In Europe… people have been hearing this catchy little tune on a
television commercial…


(Sound of commercial)


If you hate something, improve it. That’s the message of this Honda UK
commercial that highlights the historically loud, smelly diesel engines.
It’s intended to promote Honda’s new, cleaner diesel, something it’s
launching in Europe.


Diesels have always been more popular in Europe than the U.S. That’s
because there diesel fuel is roughly 20 to 30 percent cheaper than
gasoline there, and diesels get great fuel economy… 30 percent better
than in gasoline engines.


Here in the U.S., diesels haven’t sold well. In the 1970s, when diesel
fuel was cheaper than gas, diesels gained in popularity briefly, but people
didn’t like the stench of the smoky fumes and the clunky sounds of diesel
engines. Those lingering attitudes have scared Honda off from bringing
its new diesels here.


But Daimler/Chrysler is trying to change all that. The company is
drawing on its European expertise to bring advanced technology diesels
to more U.S. passenger cars, and now, they think Americans will buy
them.


Jim Widenbak is a manager of small diesel systems for Daimler/Chrysler.


“We think that there’s a niche for diesels in the North American market,
and We’re not sure exactly how big, but I would characterize us as kind
of bullish on diesels. We really think there’s a place for them and
that customers will ultimately be very happy with diesel products.”


Daimler/Chrysler currently offers a diesel engine on its newer models of
the Jeep Liberty and the Mercedes E-320. Sales of these vehicles were
more than double what the company expected – 10,000 for the diesel
Jeep Liberty and 5,000 for the E-320.


Widenback says that electronic controls have improved over the past 30
years, making diesels better performing, more fuel efficient and cleaner
burning.


The company is in negotiations with the Environmental Protection
Agency to use a new technology, currently in use in Europe, that cuts
pollution further – just in time for tough new federal emission controls
that take effect by 2008. The process uses a material called urea that’s
injected into the exhaust before the exhaust hits the pollution control
device. This ultimately removes troublesome emissions of nitrogen
oxides.


There is one problem with the pollution control system, though.
Anthony Pratt directs power train forecasting for J.D. Power Automotive
Systems. He says the car periodically will run out of its supply of urea.


“So, in other words, you’re not getting the injection of urea in the
exhaust, the vehicles will continue to perform normally as if the urea
tanks were full but they will not meet the more strict emission
standards.”


If the company finds a way to ensure the tanks stay full, Pratt thinks it
will work. Pratt projects diesel engine sales will grow from 3 percent of
the market in 2005 to seven and a half percent in 2012, overtaking sales
of hybrid vehicles, which are only projected to be 4% of the market.


“I think the vehicle manufacturers will be successful in ultimately
educating the consumer in that the new diesel technology is not the dirty,
clanky, loud and sluggish technology they may be familiar with from the
late 70s and early 80s.”


(Sound of car dealership)


That message – that diesels are worth buying – is falling on deaf ears for
the customers of Schultz Motors. Tyler Shultz, the general manager, doesn’t
think it will fly, based on what he’s seen.


“As diesel prices went up in the last six months to a year, we virtually
have lost interest. Again, it’s not that the consumer doesn’t want it, but
when they see fuel prices go above gasoline prices, it was almost like
somebody flipped a switch.”


Shultz says it’s too expensive to buy and maintain a diesel and customers
won’t recoup the cost savings from better fuel economy unless they own
their car for several years. He, and some other dealers in the area don’t
think diesels will ever become popular.


Daimler/Chrysler’s Widenbak disagrees. He expects those fuel prices to come
down, and as they do, he says people will start buying diesel vehicles.


“We’re confident that our vehicles, diesel vehicles in general and our vehicles
specifically, can appeal to people.”


Daimler/Chrysler is so confident, it expects to roll out diesel engines in
more of its passenger cars over the next few years.

Suv Makers Digesting New Fuel Standards

Automakers say meeting the government’s new fuel efficiency standards
for light trucks will be a challenge. The final standards were issued
last week (Wednesday, March 29th). For the first time, the largest SUVs
will have to meet the standards. The GLRC’s Tracy Samilton reports:


The Alliance of Automobile Manufacturers calls the new standards the
most sweeping change to fuel economy rules in 30 years. Light trucks
include SUVS, minivans, and pickups, and account for more than half of
all new vehicles sold in the U.S.


Alliance spokesman Charles Territo says the set of rules will take weeks
for automakers to digest.


“Which happens to be about the size of a major city phone book. It’s
about 550 pages.”


Territo says one change is big SUVs like GM’s Hummer and Chevy
Suburban will no longer be excluded from fleet wide averages. And that
will probably mean more alternative technologies on the big trucks, like
hybrid and diesel engines and fuel cells. That isn’t enough for many
environmental groups, who say the changes won’t do much to reduce the
nation’s dependence on foreign oil.

Divining Future of Fast Ferries

High-speed ferries have come to the Great Lakes. A ferry between Toronto and Rochester, New York, is scheduled to start this week – joining another ferry that started earlier this month between Milwaukee and Muskegon, Michigan. But transportation experts say it isn’t clear that the fast ferries will prosper. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:

High-speed ferries have come to the Great Lakes. A ferry between Toronto, Canada,
and Rochester, New York, is scheduled to start this week, joining another ferry that
started this month between Milwaukee, Wisconsin, and Muskegon, Michigan. But
transportation experts say it isn’t clear that the fast ferries will prosper. The Great Lakes
Radio Consortium’s Chuck Quirmbach reports:


The privately owned Lake Express ferry between Milwaukee and Muskegon cuts across
Lake Michigan at nearly forty miles per hour. Four diesel engines drive high-powered
jets underneath the catamaran-style boat. The jets shoot huge plumes of water out the
back end of the nearly 200 foot-long vessel.


(sound of ferry)


It only takes two and half hours for the Lake Express to make a crossing, about half the
time of an older ferry that travels across northern Lake Michigan. A Milwaukee-based
passenger named Jack says the faster pace is what draws him to the new boat.


“This is quick… we’re all about being quick.”


The Lake Express also has room for 46 cars and smaller vehicles such as motorcycles. A
motorcycle passenger named Bobbie says using the ferry is a breeze, compared to driving
around Lake Michigan and fighting traffic in Chicago.


“Have you ever ridden a motorcycle and had a semi pull up behind you? I mean, it
seemed like he was that far away, maybe two feet, and it’s very frightening and it’s
happened to us several times.”


Some people who study ferries say less stress and time savings are just two of the appeals
of the boats. University of Delaware professor James Corbett says fast ferries have a
certain cachet for the upscale, leisure tourist.


“Fast ferries are very, very attractive first choices when people are considering new
routes… they look for the latest and greatest vessel designs.”


But Corbett says the ferries have several drawbacks. For one thing, the faster boats use
more energy and that helps push up ticket prices. Adult roundtrip fares for the
Milwaukee to Muskegon route start at 85 dollars.


Sue McNeil heads the University of Illinois-Chicago Urban Transportation Center. She
says the fares may scare off repeat business in certain markets.


“Just what I know about travel patterns and where people go, the Rochester-Toronto
seems to make more sense than the Milwaukee to Michigan.”


Still, McNeil says she hopes all the ferries succeed, because they provide another
transportation option. Federal, state and local governments are buying into the concept,
by offering some subsidies to promote the boats and build docking terminals. Chicago
and Cleveland are also looking at adding the faster moving ferries.

Off-Road Diesels to Clean Up

The Environmental Protection Agency says a new rule will cut down on pollution from stationary diesel engines. It applies to industrial equipment like backhoes and forklifts, and to farm tractors. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:

The Environmental Protection Agency says a new rule will cut down on pollution from
stationary diesel engines. It applies to industrial equipment like backhoes and forklifts,
and to farm tractors. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:


The EPA says the measure will prevent up to 12,000 premature deaths, a million lost
work days, and 15,000 heart attacks every year.


The new rule aims to do two things: clean up diesel fuel, and clean the exhaust from
diesel engines. Doug Aburano is with the EPA.


“The engine manufacturers have agreed to produce a catalyst that would reduce
emissions from these engines, while we also have an agreement from the diesel producers
to reduce the sulfur content to such an extent that the sulfur would not poison the
catalysts that the engine manufacturers are doing. So you have to do a collaborative
approach like that to get to the huge reductions we’re looking at.”


Aburano says emissions of soot and smog will be cut by 90%. It will take several years
to accomplish that, as businesses and farms replace old equipment. Health and
environmental organizations are welcoming the measure.

Budget Calls for Cleaner School Buses

The Bush administration has proposed a funding increase for a nationwide program to reduce pollution from diesel school buses. The Great Lakes Radio Consortium’s Erika Johnson reports:

The Bush administration has proposed a funding increase for a nationwide
program to reduce pollution from diesel school buses. The Great Lakes Radio
Consortium’s Erika Johnson reports:


The Environmental Protection Agency launched a program last year to cut
emissions from diesel school buses. Five million dollars was divided among
a handful of school districts nationwide. The money was used to replace or
retrofit diesel school buses with pollution control devices and to provide
cleaner burning diesel fuels. Now, the Bush administration has proposed
that an additional 65-million dollars be added to the program next year.


Tom Skinner is EPA’s Region 5 Administrator.


“The reason for the big jump is that we’ve seen the kind of success, the
kind of results that can be created by the program, and what we’ve found is
it’s tremendously effective. We started with a relatively small pilot
program with limited funding, and now is really when we’re going to kick it off, and
expand it dramatically and really reach across the country.”


Skinner says EPA hopes to replace or retrofit all diesel school bus engines
by 2010.

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.

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.

Cleaning Up the Dirty Diesels

The rule in driving these days seems to be that bigger is better, with
light trucks and sport utility vehicles overtaking the road. But as
automakers bask in their high profits from the pricey vehicles, a new
challenge looms…how to make them more fuel efficient. The trucks guzzle
substantially more gas and emit more pollutants than passenger cars and
the government is putting pressure on automakers to clean them up. Now,
an unlikely candidate is emerging to solve the problem. The Great Lakes
Radio Consortium’s Julie Edelson Halpert reports:
