Some cities are trying to save some money by recycling trains. They’re renovating and re-using their old mass-transit rail cars. Joyce Kryszak went to find out just how you go about recycling a train.

It’s hard to say whether there are more roads or train tracks running through the small town of Hornell, New York– a couple of hours southeast of Buffalo. The acres and acres of tracks of the old Erie Railroad yards are here. And for more than 150 years, Hornell has repaired trains in its shops. But recently, it’s started completely rebuilding some passenger rail cars.

We crouch underneath one of the jacked-up 40 ton cars and Mike Bykowski shows us how.

“This is car 114, it’s the furthest along in the rebuild process, you want to step up and take a look inside?…Sure.”

Bykowski is the director of engineering for the Niagara Frontier Transportation Authority in Buffalo. And he’s in charge of overseeing the renovation of the Authority’s twenty seven light rail cars. Bykowski says after a quarter century of harsh Buffalo winters, the city’s rail cars were showing their age.

“The older cars that are out in the system right now, there’s a fair amount of rust along the bottom of the vehicles.”

“What we have done is when we replaced the frame we also replaced approximately 18 inches with stainless steel, which is a corrosion proof material.”

So, not everything on the old cars is reused. Workers at the Gray Manufacturing Industries shop are stripping down the first two cars to their shells. They’ll put in new sidewalls, new windows and seats. New electronic signage and audio systems also will be installed. But Bykowski says there’s a lot being recycled too.

“You’re saving all the steel, a lot of wiring that would have to be replaced. You’re saving copper. You’re reusing parts that are there.”

Bigger components are saved too.

The trucks and wheels are being patched, polished and eventually reattached to the cars.The motors will be rehabbed and go back into service too.

But, to be honest, Buffalo’s transit authority didn’t decide to recycle its rail cars because it’s good for the environment. It’s just trying to save some money. You see, rehabbing the cars costs about a million dollars each. That’s a third of what new cars cost.

Dave Gray is president of GMI, the company renovating the cars. Gray says they’re rebuilding cars for the Chicago and Philadelphia transit systems too.

“Most transit authorities try to rebuild vehicles. They always reach their mid-life, which is what the NFTA’s vehicles [have] done, and it’s very cost effective, so refurbishing makes a lot of sense.”

Not every city has had to be so frugal. Recently, some cities received federal stimulus money for their light rail systems. And a few of them, such as San Francisco, Washington D.C. and Miami, are simply going out and buying a brand new fleet. It is a whole lot easier and faster. It’s going to take three years to refurbish all of the rail cars in Buffalo’s fleet. Larry Meckler heads Buffalo’s transit authority. Meckler says he certainly doesn’t blame other cities for scrapping their fleet.

“If there’s other jurisdictions that can pull it off and get new cars, I’d say get the new cars because it’s a lot of effort, a lot more work, a lot more engineering – but they cost less. So, obviously, if we had the money and life was great and this was a utopian situation, every time a car hit [the end of] its usefulness, I’d just go out and buy another one.”

Still, being fiscally responsible is paying off. The authority saved taxpayers a lot of money. And in the end, Buffalo’s refurbished cars will look and work as every bit as good as new ones. Plus, even if it was unintended, the transit authority’s decision to reduce, reuse and recycle does let it claim the moral high ground.

Parrots in Brooklyn

Think ‘city bird,’ and you probably
think ‘pigeon.’ But in some cities,
another kind of bird is thriving –
the bright green monk parrot. Some
people love them; some people hate
them. Samara Freemark
went to Brooklyn to find them:

No one really knows just how the parrots got to Brooklyn. But the best guess is they were shipped here from Argentina in the 1960s. They were supposed to go to pet stores. But somewhere along the way someone opened a shipping crate and the parrots escaped. Now there are thousands of the birds in colonies across Brooklyn.

“They’ve reinvented themselves as a north American species.”

That’s Steve Baldwin. He’s a tall, white haired native New Yorker and, I think it’s fair to say, a parrot fanatic.

“It has probably something to do with the peculiar person I am. I think I probably regarded myself as an outsider for most of my life. And so the idea you could have these creatures who really don’t belong here, somehow make the transition and now they belong here. I just found that a personally inspiring story.”

Steve started a website about the parrots. He leads monthly parrot tours. He even wrote a song about the parrots.

“I got some news for you baby and it might not be so good. There’s an avian invader in the neighborhood. Well, they’re little green parrots from the Argentine…”

I met up with Steve as he was starting one of his tours of the parrot colony at Brooklyn College.

“I’ve been following these little green guys for about 5 years. One of the things that endears it is that it’s very smart. In fact the monk parakeet is the second best talking parrot. Next to the African gray, the monk parrot is number two. Are there any particularly Brooklyn sounds that they… well, occasionally you’ll find one that’s imitating a car alarm.”

We head over to the college’s soccer field.

“Sometimes when we come out here we’re lucky and the parrots are down on the ground, eating the grass. But I don’t see them today. So we’re just going to keep moving. Uh! Here they come! There they go! We got a good group.”

There are probably 50 parrots living in the Brooklyn College colony. But it’s one of many colonies across New York. There are about 450 parrot nests in the city. That’s according to numbers from Con Edison, New York City’s energy provider.

Con Edison tracks the nests because for the company, the parrots are actually a pretty big headache. A couple of days after the tour I met up with Chris Olert. He’s Con Edison’s point man for dealing with all problems parrot-related.

“What happens is, these birds build nests around our transformers, because of the warmth. And these are not little hold in your hand nests. Some are three or 4 or 5 feet tall, and 3 or 4 or 5 ft wide. They’re huge. And they do catch on fire. And those fires have resulted in customers losing their electricity.”

Con Edison has been trying to figure out what to do about the parrots for years now. They tried knocking the nests down – but the parrots came back and rebuilt. Last year they even installed some mechanical owls with rotating heads to frighten the parrots away.

“The owl was – some of our people who work in the overhead in Queens spotted these owls in a hardware store and put them up on the equipment, but the parrots pretty much laughed in their faces.”

Nothing has really worked. Olert says Con Edison’s numbers show the New York parrot population growing by 10% every year.

At that rate, in a couple of decades they could be as ubiquitous – and as hated – as that other New York bird – the pigeon.

Nyc to Turn Yellow Cabs Green?

  • NYC has new incentives to try to get more hybrid taxis, like this one, on the road (Source: Momos at Wikimedia Commons)

When big cities think about putting more fuel efficient, less polluting cars on the road, the first color that comes to mind isn’t green — it’s yellow. There are so many cabs on city streets, they seem like a good place to start environmental initiatives:

Transcript

When big cities think about putting more fuel efficient, less-polluting cars on the road, the first color that comes to mind isn’t green— it’s yellow. There are so many cabs on city streets, they seem like a good place to start environmental initiatives. In New York City, the mayor has a plan to replace conventional cabs with gas-electric hybrids. But not all taxi drivers are thrilled about the plan. Samara Freemark talked to some of them:

Ask a New York city cabbie what kind of car he drives, and chances are, this is what you’ll hear.

“Crown Vic.”

“Crown Vic.”

“Crown Vic.”

Cabbies love this car. It’s this big, solid, safe thing. It’s got a lot of leg room. It’s easy to repair.

But it burns a lot of gas. And that means a lot of pollution, especially when you realize that there are 13,000 cabs in New York City. All that pollution contributes to asthma, heart disease, and a mess of other health problems.

And that is why New York mayor Mike Bloomberg has it in for the Crown Victoria.

Bloomberg has a plan. He wants to use market incentives to encourage cab companies to buy hybrid.

“To turn NY City’s yellow cabs green.”

Cute slogan.

But Bloomberg isn’t messing around. Just ask the reporter who challenged the idea at a press conference.

“The taxi owners who oppose your plan say it’s deeply troubling that the city is…”

“I think it is more deeply troubling that they’re trying to kill our kids.”

Tough talk, right? But here’s how Bloomberg’s plan would actually work.

A lot of cabbies don’t own their own cars – they lease them from cab companies.

Bloomberg wants to lower the fee companies can charge drivers to take out Crown Victorias. So company owners would make less money on conventional cars.

And he wants to let cab companies charge drivers more to take out hybrids. Companies that chose those cars would make more money, giving them a reason to go green.

There’s something in it for the drivers, too. Although have to pay more to rent the hybrid cabs, they’d make up that money, and then some – a big chunk, actually – in gas savings. Bloomberg says hybrid cab drivers could save hundreds of dollars a year under his plan.

It sounded like a win-win-win situation: good for cabbies, good for cab companies, and good for the environment.

So I went out to the curb to ask some cabbies what they thought of the mayor’s idea.

“I wanted to ask you about hybrids.”

“Hybrid taxi? Yes.”

Sukhinder Singh hadn’t heard about Bloomberg’s plan, but he liked it.

“That’s not a bad idea. You’re not spending any extra money. 3, 4 dollars or 10 dollars extra, you know that later on when you go home you get it back because if you spend less on gas. It helps also for the pollution too. Lot of cabs around NYC, so all pollution.”

But a lot of cab drivers – especially veteran drivers – are not that enthusiastic. They are worried that hybrids aren’t safe. They are worried that hybrids are too small. They are worried about the time and money it takes to repair a hybrid. And most of all, cab drivers like Lal Singh are worried about giving up their Crown Victorias.

“Of course we wish not to pay more money for the gas. But I prefer to keep this poor Crown Victoria. This car makes us live. This Crown Victoria is a very big time strong car. These hybrids, they are not for taxi. They are very small, very unsafe, very unfit.”

So you get the idea – he doesn’t like hybrids.

And there’s one more problem with Bloomberg’s plan. It looked pretty good when it came out, when gas was 4 dollars a gallon. But prices now are about half that. That means cabbies don’t save that much money when they pick a hybrid. And so they have even less reason to give up their beloved Crown Vics.

Micky Maynard is a reporter
for the New York Times. She’s been keeping a
diary of giving up her Lexus SUV for a hybrid
gas-electric car. She’s taken her readers on
a ride through her reasoning for switching
and her on-road experiences. The Environment
Report’s Lester Graham took a ride with Maynard
in her Barcelona Red Toyota Prius:

Micky Maynard: “Okay, so, to start it, you push this button. You see
the little ‘ready’ button, and you hear a little sound, and that’s
essentially the battery starting the car. And, off you go.”

Lester Graham: “I recall, when I was younger, I went from a pretty
powerful car to a little car, and the one thing I really noticed was
that it felt like I was driving a toy. What’s the difference between
driving the Lexus and driving this one?”

Maynard: “A difference is that in the Lexus, or in a SUV, you’re sitting
up above the ground. This car, you’re right back down on the road.
And it took a lot of adjusting. I was driving from Detroit to Chicago,
and I heard this ‘thump, thump, thump,’ and I thought I had a flat
tire, but it was just the road surface. Because I was used to sitting
up high, I never would have noticed the road bed before.”

Graham: “I know that some newby Prius drivers that when they
come to a stop, like we are now, there’s almost no sound
sometimes.”

Maynard: (laughs) “That’s right. In fact, my postman was telling me
hybrid cars will come up behind him, and he says, ‘they’re sneaky
little cars.’ He said, ‘you can’t hear them.’ (laughs)

Graham: “What’s it like going on to the on-ramp on the interstate?”

Maynard: “I haven’t had any trouble yet, because I generally try to
give myself enough space between myself and the person behind
me. You know, when you’re in a luxury car, a Lexus, you hit the
pedal and you get all this acceleration. This car’s quite peppy, but it
doesn’t have that rrrrrrrrrrrr that you get in a V8 or a V6. And that is
something to get used to.”

Graham: “I keep hearing from Prius owners that the consumption
meter really changes how they drive. How has the feedback from
the car affected how you drive?”

Maynard: “It affects how I drive tremendously. There’s a
consumption screen in the car, and it will show you exactly the kind
of miles-per-gallon you’re getting. So, if you don’t floor it, you can
get 100 miles-a-gallon – at least that’s what the car’s telling you. And
you have another meter that shows you what you’re averaging over
your trip. My pride and joy was driving a long trip and getting over
50 miles-a-gallon. And you kind of feel this little shot of pride when
you see the 50 or the 47.”

Graham: “So, you’re encouraged to take it easy just so you can be
rewarded with the feedback?”

Maynard: “And I don’t want people to think that Prius owners are all
out there going 17 miles-per-hour. We’re not. What’s going on is
we’re trying to drive smoothly, we’re trying to drive in a steady
fashion. Although they tell you that you get better gas mileage in
town, driving around city streets, I’ve actually gotten fantastic gas
mileage just driving steadily on the highway. You do keep the
consumption meter up on the screen, and you do watch it. Now, I
did have one reader write in and say, ‘stop watching the screen and
watch the road,’ and I assured her that I absolutely do watch the
road. But you do sort of glance over and kind of check how you’re
doing.”

Paddling Through Pollution

A group of New Yorkers is trying to convince people to get out on one of the most
polluted bodies of water in the country- literally out there, in canoes. Samara
Freemark reports that they hope once people see the water up close, they’ll realize
just how dirty it is. And maybe then they’ll help clean it up:

(sound of water, paddling)

You wouldn’t believe the stuff people have pulled out of the Gowanus Canal.
Refrigerators. Bathtubs, rusted cars. A 5000 pound dead whale. A suitcase full of
human body parts. Sewage floods into the canal all the time. So you see everything
people flush down their toilets. The water itself is a sickly, opaque green.

And that’s just the stuff you can see. The canal used to be a dumping ground for the
factories that line it. And the sediment at the bottom is still full of a laundry list of
toxic chemicals: cyanide, mercury, lead, asbestos. Scientists found strains of
gonorrhea in a water sample just last year.

And I’m sitting in a canoe in the middle of it.

(water noise, “Ewww, oh, God, gross. It’s like a subway down here.”)

The Gowanus is a 2 mile long trough of murky water that flows into the New York
Harbor – though the word ‘flowing ‘ is a bit optimistic, since the water mostly just sits
there.

You wouldn’t think anyone would want to canoe in this kind of water – much less
see it as a good way to spend a lazy summer afternoon.

(Laughs.) “ My first day was like, hell no. I knew it was going to be nasty.” (Laughs.)

That’s Alex Kovaleski. She’s a Dredger, a member of a group that gets together to
canoe the Gowanus.

“But I’m always looking for an adventure or a way to see things from a new
perspective, so I went out. And then I started having dreams about it, and it was all
over.”

Kovaleski knew she had to do something.

So almost every summer weekend she and the Dredgers gather at a makeshift pier
and paddle up and down the canal.

They invite others along. Anyone who shows up can jump in a borrowed canoe and
take it for a paddle. They get a lot of first-timers, New Yorkers who have heard about
the trips and come for the novelty or to get a taste of nature in this most urban of
cities.

That’s why Stephen Kline and Beatrice Aranow came. This is their first time at a
Dredgers event. I speak with them on the pier, before they step into a canoe. They
say they came because they love nature, they love being out on the water, and they
want to see their city from a whole new perspective.

Stephen and Beatrice are in for a big surprise. Twenty minutes later, they had their
new perspective.

(talking over each other) “ There were like dead rats, turds. It was a lot worse than I
could have ever imagined. It wasn’t that mysterious. I actually thought I was going
to have a pleasant time going out but it was pretty intense. It was repulsive.”

This doesn’t sound like a ringing endorsement of the Dredgers.

But Alex says Stephen and Beatrice’s reaction isn’t that bad – it’s actually kind of the
point.

“Part of it is just being out there with the poop and the trash, like, hah, here it is,
there’s no getting away from it. When you’re in it, you’re naturally longing to see it
restored.”

A week later I came back to the Gowanus canal for another Dredgers event. This
one’s a cleanup day, and volunteers are out with rubber gloves and bags, picking up
trash. It’s kind of a festive scene- there’s music and free pizza. And there’s a group of
high schoolers who came to spend the day canoeing and helping out.

(students talking about canoeing, cleaning)

Alex says those students are who the Dredgers really want to reach. The Gowanus
isn’t going to be clean anytime soon. But those kids are going to grow up, and they’re
going to be tax payers and voters. Soon they’re going to make the decisions that
decide the future of the canal.

Researchers and environmentalists are
experimenting with a new method for collecting
biological samples in the wild. They’re using
trained tracking dogs to sniff out everything
from rare plants to moose pellets. Brian Mann
joined the hunt in New York’s Adirondack Mountains:

It’s early, the sun still tangled in the alder trees, when we set off
on foot down a
narrow logging road.

(sound of walking down the road)

Soon, Heidi Kretser with the Wildlife Conservation Society finds the
first evidence that
we’re not alone.

“These are moose tracks.”

New York’s moose population has surged in recent years, to move than
500 animals.
Researchers have been tracking moose using airplanes and radio collars.

But today, were tagging along behind a cheerful black lab mix named
Wicket.

(sound of dog’s collar jingling)

Wicket flashes back and forth across the trail, snuffling eagerly.
She wears a bright
red vest and that tinkling bell is designed to keep her from actually
meeting a moose
head-on.

Her owner and handler, Aimee Hurt, says using dogs to find biological
samples – everything from plants to rare birds – isn’t new.

“I think if you talk to a lot of biologists who’ve been out
in the field for
decades, ‘Oh yeah, my dog figured out that we were looking for —
whatever.’ And they
started honing in on it and helping out. So I really think that dog’s
have been
biologists’ partners for a long time.”

Hurt’s organization – Working Dogs for Conservation, based in Montana
– took the idea
one step further, training dogs in much the same way that police train
K-9 units.

Wicket knows how to find six different kinds of scat, including
mountain lion, grizzly
bear – and now moose

“She is an air-scent dog, which means there’s no tracking
involved — she’s
just sniffing the air for a whiff of scat.”

Heidi Kretser, with the Wildlife Conservation Society, says moose
droppings can tell a
lot about why these Clydesdale-sized animals are returning to New York, what they’re
eating, and how they’ll reshape this forest if their numbers keep
growing.

“By understanding the diet, we’ll get a better sense of what
habitats they
might impact long-term, since they eat 40 pounds of vegetation a day.”

(sound of birds and footsteps)

Wicket leads the team on long ramble through the radiant lime green
forest, and down
across a burbling creek.

(sound of creek)

We see moose sign everywhere – mule-sized tracks, maple trees
stripped of bark. And
then Wicket sniffs out her first pile of droppings.

“Whoopee, good girl. Very nice!”

More poop means better data. So the pellets are trucked away in a
plastic bag for the
trip back to the lab.

For Wicket, the reward is a few minutes of joyous play with a squishy
rubber ball.

(sound of squeezing toy)

“Let’s get to work!” (bell jangling)

Then the team is off again, with Wicket snuffling happily through the
trees. Biologists
hope to use the same method to study other wildlife – from grizzlies
to mountain lions.

Grand Bridge Scaled Back for Birds

There are few things as aggravating as getting stuck in a traffic jam. But for some drivers crossing a busy bridge from the U.S. to Canada there’s aggravation on top of aggravation.

There are few things as aggravating as getting stuck in a traffic jam. But for some drivers crossing a busy bridge from the U.S. to Canada there’s aggravation on top of aggravation. Joyce Kryszak reports that’s because a plan to build an additional bridge is being blocked by concern for a bird and a little fish that it eats.

Every year, millions of people cross the mighty Niagara River on the Peace Bridge that connects Buffalo, New York to Canada. And many of them sit for hours in a traffic jam. The border crossing and passport checks slow things down. But there are just not enough lanes for all the traffic.

Ice delivery man Tim Holliday is one of those who is fed up with hours and hours of bridge delays.

“Like, I gotta go to the duty-free here, and when I’m coming out of here I have to go through customs and they always ask, what were you doing in Canada?” said Holliday. “I’m just sick of the hassles, you know?”

Transportation officials say a new bridge is needed. The traffic problems will only get worse. Because of increased trade, about eleven million additional travelers are expected to be using the Peace Bridge over the next decade.

And that’s a headache for Ron Rienas. He manages the busy international bridge crossing. He says building a new bridge would help with the traffic delays and help with national security.

“This is a border improvement project designed to address redundancy issues, security issues, traffic flow, all of those things, maintenance issues…all of those are impacted by not being able to proceed with the project,” said Rienas.

A second bridge has been designed. It’s a cable-stayed bridge with towers as high as the Washington monument.

Brian Higgins is Congressman for the area. He’s pushing for federal approval of the impressive cable design. He says the region needs an iconic symbol of progress.

“We are in the eleventh hour of a project that’s been going on for fifteen years. We need additional capacity at the Peace Bridge to promote the efficient, predictable flow of commerce between the United States and Canada – we need an iconic bridge, a signature bridge,” said Higgins.

But that signature bridge is exactly the kind of design that is dangerous to many birds.

And the Niagara River is a virtual highway for nearly three hundred kinds of birds. The cables can be invisible to the birds and they can fly into them and die.

Among those birds is the Common Tern. It’s an endgangered species.

Terry Yonker knows these and other birds better than most.

“We probably documented somewhere in the range of half a million birds, and there’s a common tern right there.”

Yonker is a scientist and a former Ornithological Society president. He wrote an environmental study that recommended against the bridge’s cable design because it could kill hundreds of different kinds of birds, including the endangered tern.

Yonker says even if it avoided hitting the cables by flying over the bridge, the tern would be stressed by such a tall bridge design. That’s because it has to make eight trips over the bridge each day to feed its young. But he says it probably wouldn’t make that many trips if the new bridge is any higher than the Peace Bridge.

“You raise that structure and they’ll have to spend a lot of energy doing that. They’ll maybe make five or six trips a day and that means one or two chicks are going to get less food out there,” said Yonker.

The other concern is a food source for the tern.

Fishery experts say the enormous piers would change water currents, eventually killing off the Emerald Shiner. That’s the tiny fish the endangered bird feeds on.

So a new design is being recommended: A lower bridge with smaller piers to protect the tern and the emerald shiner.

Federal and state agencies are working to find a way to mitigate the threat to the birds and fish by altering the plans for the new bridge. But environmental experts say you can’t mitigate extinction.

Environmentalists and some biologists say the common tern is more than an endangered bird. They say it’s a warning, about what happens when sound science is ignored for the sake of progress.

But, try explaining that to the people stuck in traffic for hours because a second bridge is being blocked to save a small bird and a little fish.

Scientist Tracks Air Mysteries

The Great Lakes region is home to major power producers. But along with the electricity they make comes some amount of air pollution. When coal-fired power plants in Illinois and Ohio emit sulfur dioxides, prevailing winds blow them to the Northeast, where they can fall as acid rain. Several northeast states are suing those power plants to clean up their emissions. Earlier this summer, a professor at Clarkson University in northern New York coordinated a unique study to learn more about the life cycle of air pollution, from where it’s produced to where it lands. The Great Lakes Radio Consortium’s David Sommerstein has the story:

The Great Lakes region is home to major power producers. But along with the electricity they make comes some amount of air pollution. When coal-fired power plants in Illinois and Ohio emit sulfur dioxides, prevailing winds blow them to the Northeast, where they can fall as acid rain. Several northeast states are suing those power plants to clean up their emissions.


Earlier this summer, a professor at Clarkson University in northern New York coordinated a unique study to learn more about the life cycle of air pollution, from where it’s produced to where it lands. The Great Lakes Radio Consortium’s David Sommerstein has the story.

Chemical engineering professor Phil Hopke will take any opportunity to get out of his office and over to his field lab. It consists of a concrete slab amongst the weeds in a corner of the local airport. Installed on the concrete are monitors he uses to find out exactly what’s in the air we breathe.


(sound of opening lock)


Hopke unlocks a gate in a chainlink fence. You can already hear a strange hum in the distance. It gets louder as Hopke strides up to one of three white machines the size of dishwashers.


“Come out and change the filters once a day. This one’s for organic constituents in the air.”


He pulls out what looks like an air filter for your furnace. These machines suck in air. They leave a unique footprint of chemicals on the filter that represents what was in the air in this place on this day — chemicals like sulfur dioxide and mercury. Hopke will send these filters to specialty labs around the world to be analyzed.


There are hundreds of stations like this in North America. Groups of researchers study daily air quality for every region of the country. They examine how things like traffic and smokestacks might affect the air we breathe.


But Hopke says they mostly focus on their own areas. They don’t often coordinate studies to see how the chemicals they find move from region to region.


“It struck me a couple of years ago, particularly in the Northeast, that we have these groups talking to one another.”


Working with the U.S. Environmental Protection Agency, Hopke convinced 26 sites in the East, from Texas to Toronto, to measure the same stuff on the same days. They chose the whole month of July.


It’s perhaps the largest simultaneous air sampling effort ever conducted in this country. When the data’s complete, the study will track the lifespan of pollution, from when it leaves a smokestack or a car’s tailpipe to when it is taken up by a tree or your lungs.


But scientists can’t just follow one molecule of pollution from a car in St. Louis to a lake in Michigan. They have to make models of how the chemicals move, like how meteorologists make weather maps to trace storm systems. As if that’s not complicated enough, says Hopke, naturally occurring chemicals make the job even tougher.


“You have to keep in mind that the Blue Ridge Mountains in Virginia are blue because of natural photochemical smog, particles being formed because of the pine materials that come off. Those materials that you smell are chemically reactive and will undergo the same type of smog reactions as human emitted materials.”


So researchers use techniques to separate out the “man-made” pollutants from the “natural” pollutants. Next they look for high concentrations of, say, sulfur dioxide in Chicago on July 15th. Then they follow those high levels east with prevailing winds. They look for high sulfur dioxide levels in Ohio or New York a few days later. After doing this many times in July for many types of chemicals, the researchers hope patterns will begin to emerge.


Hopke sits on a scientific advisory committee that helps the EPA develop pollution standards. He says this coordinated study will bring stronger science to the EPA’s sometimes controversial decisions.


“Suppose I require all power plants to reduce their sulfur dioxide emissions by twenty percent. What does that do for me for particle concentrations in New York City? What will that do? Will that get us where we want in terms of clean air?”


With a study this large in scope, the answers to those questions won’t come quickly. The massive amount of data gathered in the study will take a few years to interpret.


In the meantime, Hopke and the EPA are planning another cooperative sampling effort for wintertime, when temperatures and people’s habits are different from summer.

Commentary – A New York State of Mind

Earlier this month (November), the U-S justice department filed the
latest in a string of lawsuits aimed at reducing pollution from coal
fired generating stations. As Great Lakes Radio Consortium
commentator Suzanne Elston points out, instead off wasting all their
time suing each other, the jurisdictions involved should follow the
example set by New York State:
