A new report finds some of the cities with the worst air pollution are breathing a little easier. Lester Graham reports.

The American Lung Association’s annual “State of the Air” report uses the latest data from 2006, 2007 and 2008. That’s just before the economy really tanked. Janice Nolan is with the American Lung Association. She says even though factories were still running at full tilt, improvement in air quality was seen across the nation. Particularly in cities the group watches closely.

“We’ve tracked some of the 25 most polluted cities each year to see how they’re faring and in each case we saw significant improvement in most of the cities in those twenty-five.”

Nolan says cleaner diesel fuel and new less polluting trucks… along with some improvements at coal-burning power plants helped. But she says other dirtier coal-burning plants and older diesel trucks continue to pollute the air.

The coal industry wants us to
believe in the idea of ‘clean coal.’
But burning coal emits a lot of
carbon dioxide, the greenhouse
gas contributing to climate change.
The coal-burning electric power
industry is just now testing technology
to capture CO2 and to permanently
store it. The second round of tests
is happening at American Electric
Power’s Mountaineer Power Plant
in New Haven, West Virginia. Hank
Courtright is monitoring those tests.
He’s with the non-profit Electric Power
Research Institute. Lester Graham
talked with him and asked how the
tests are going:

Hank Courtright: We think it has great progress, it’s really the second step of a multi-step process that we’re doing. We had just concluded a project up in Wisconsin on a smaller scale, the same type of technology, and it was very successful. It capture 90-plus percent of the CO2 that passed through it and saw some great promises as far as reducing the cost of doing it. The idea here is that we’re scaling it up ten times larger at the mountaineer plant and so far the early results seem very good and we’ll continue to test that over a year plus to see how it does produce.

Lester Graham: I understand it takes a lot more energy to run this extra CO2 capture equipment, as much as 30% more coal has to be burned to generate the same amount of electricity, what’s being called a parasitic load. What’s this going to mean for our power bills?

Hank: Well, what we’re trying to Lester is that the parasitic load gets down into the, let’s say, the 10 to 15% range. If you get to that level, it means that the electricity out of a coal plant might be about 25% higher than it is. But right now coal is basically the cheapest form of producing electricity, so it still ends as being an economical option even if you might be increasing the cost of that coal plant by about 25%.

Lester: If they can accomplish that with this experiment, how long will it take to get this technology built into the bulk of coal burning power plants?

Hank: Well, you’re going to be working over this for several decades, really. If this plant at Mountaineer works well, our thinking is around 2020 you’re going to be able to have most new coal power plants use the carbon capture and storage. And you might be able to retrofit about 20%, 25% of the existing plants in the United States with this type of technology.

Lester: If all of these methods fizzle, we can’t capture carbon economically, or at the other end, we can’t find a way to sequester this carbon underground, or whatever type of method they can come up with, what’s next?

Hank: Well, that causes some difficulties because right here in the United States coal is used to produce about half our electricity. And if it doesn’t work on coal, it’s also the issue that it won’t work on any other fossil fuels such as natural gas, which produces about 20% of our electricity. So you’re into a difficult situation that if you’d wanted to significantly reduce the CO2 emissions to improve the climate change issue, then you’d have to be looking at a combination of probably nuclear power and a very large roll out of renewable energy. Both of those would have to take the lion share of electricity production. But our hope is that we can get this working because it is not only here in the US that you need it on fossil fuels of coal and gas, but also in places like China, Russia, India, Australia, country’s that very large reserves of coal and hope to use those natural resources.

A new study is looking at just
how well wastewater treatment
plants remove household chemicals
and pharmaceuticals from water.
Samara Freemark reports
on why some researchers are worried
that the plants aren’t doing a good
enough job:

Most wastewater treatment plants clean water with a mix of chemicals and bacteria. But that process is decades-old. And it was designed mostly to deal with industrial pollutants.

Some people say treatment plants might not be doing a good job taking out other pollutants like household chemicals and pharmaceuticals. In fact, the treatment process can actually cause many of these pollutants to mutate – for example, some detergents break down into compounds that cause reproductive problems.

Anthony Hay is studying the issue at Cornell University.

“Hopefully they’re degraded into something non-toxic, but in some cases microbial degradation of some pollutants can actually make things worse. We need to understand what those changed products do, how they behave, and what risks they might pose.”

That’s what Hay hopes his study will help clarify.

Commercial nuclear reactors pretty
much come in two sizes: big and huge.
Companies want to create much smaller,
cheaper reactors. Shawn Allee reports they’re pitching their ideas
to the government this week:

These nuclear companies envision reactors in tiny power stations or even
factories. They expect good sales because nuclear power creates almost no
carbon emissions.

But before they can sell even one reactor, they have to go through a
nuclear gate-keeper. That’d be the federal Nuclear Regulatory Commission.

NRC spokesman Scott Burnell says, today, the government is laying out the
ground rules.

“The NRC has focused on large commercial scale nuclear power plants for
several decades. We have requirements for safety systems, for security
where these small reactor designers need to look at our requirements
closely, to make sure they can meet them.”

Burnell says some small reactor designs include technology the NRC has
never approved before.

He says it could take the government up to ten years to evaluate those
designs.

Where to Put Solar Power Plants

Transcript

Environmental groups have pushed for decades to get the federal government solidly behind solar energy. Shawn Allee reports some of them don’t like the government’s most recent effort to promote it:

The Federal Bureau of Land Management developed 24 “solar energy study areas” in Western states.

The idea is to identify federal land that might be be good for solar power plants.

Some environmentalists scoured maps of these solar study areas and got concerned.

Jeffrey Morgan is with Tahquitz Sierra Club in California.

Morgan says a solar plant can take up hundreds of acres, and construction could disturb desert tortoise and cactus habitat.

“They have no concept the desert is a vital, living place with a vast diversity of species, unspoiled landscapes and many, many other things. They they just see it as a waste-land. That’s just not true – it’s not a waste-land.”

The Bureau of Land Management says the “solar energy study areas” are just that – they’re for study – and the government would not let solar energy developers disturb critical wildlife habitat.

Dollars and Streams

  • A creek runs through Melvin Hershberger's farm in Holmes County, Ohio. He was able to clean up the water with money from the Alpine Cheese Company. The company needed to offset phosphorous pollution from its factory, so it pays farmers to reduce their manure runoff. (Photo by Julie Grant)

When you hear about dead zones in the Gulf of Mexico and the Great Lakes, they’re largely caused by pollution draining from the farm belt. It can take a long time and a lot of money to reduce pollution at factories. So they’re starting to pay farmers to cut pollution instead. Julie Grant explains:

When you hear about dead zones in the Gulf of Mexico and the Great Lakes, they’re largely caused by pollution draining from the farm belt. It can take a long time and a lot of money to reduce pollution at factories. So they’re starting to pay farmers to cut pollution instead. Julie Grant explains:

When you eat cheese, you might not realize that something so delicious creates a lot of waste. And that waste – that pollution – ends up going into the drain. It eventually ends up in rivers and lakes.

(sound of a factory)

We’re at a cheese factory in Holmes County, Ohio where they make nearly 60,000 pounds of cheese a day.

The big stainless steel vats look immaculate. But our shoes are wet.

Bob Ramseyer is CEO of the Alpine Cheese Company.

He says the floors are covered with water because the equipment is constantly being washed.

“We have a pre-rinse – that goes to drain. We have a final rinse, and that goes to drain. And we have all the floors that are flushed down and so forth, so that all ends up as part of the wastewater.”

The cheese factory’s wastewater includes not only those caustic chemical cleaners, but wasted milk by-products. One milk nutrient is the chemical, phosphorous.

About a decade ago, the Environmental Protection Agency told Ramseyer that the cheese company had to reduce the phosphorous it was releasing into the nearby river. Ramseyer was concerned.

“The equipment alone was going to cost a half million dollars. We projected it was going to cost between a half million dollars and a million dollars a year in operating costs. So we were looking for any way we could to reduce that cost. That’s where we got into the nutrient trading program.”

Alpine Cheese was among the first to negotiate what’s called a nutrient – or water quality – trading program. Instead of reducing the phosphorous coming from his factory, he pays farmers to reduce manure – another source of phosphorous – from washing from feedlots into the river.

(sound of cows)

Mervin Hershberger is an Amish dairy farmer with 125 acres and 54 milking cows.

(sound of a stream)

His farm looks like a postcard – beautiful hilly green pasture.

But a lot of the manure was washing off his farm into the streams. Herberberger says the cows were grazing right around the water.

“With the cows being in the creek we could see dirty water. The rocks were covered with dirt from cow’s waste. You walk through the stream, you’d kick up dirt and waste from the cows.”

Hershberger didn’t like it, but he didn’t have money to change it.

So when the County Soil and Water Conservation District held a neighborhood meeting to explain that Alpine Cheese was going to pay to reduce pollution from nearby farms, Hershberger saw a way to afford to clean up his farm.

He did about a dozen projects to reduce manure run-off into the water, like building a fence to keep the cows out of the stream.

And the little creek is bouncing back:

“As of now, it’s just totally clean, what you see. For the minnows and all the critters that are in the creek.”

Hershberger gets paid for the amount of phosphorous he keeps out of the water.

About 25 other farms in Holmes County are doing similar projects to reduce water pollution. And Alpine Cheese foots the bill. In exchange, the company doesn’t have to clean up wastewater coming from the cheese factory.

It’s a lot like a cap and trade program on water pollution.

There are a growing number of small programs like this around the country. But some people are trying to create water trading projects on a much larger scale.

That would mean a factory in one state might be able to pay farmer in another state. Eventually, all of the thousands of factories in just one river basin could pay farmers enough to reduce dead zones like the one in the Gulf of Mexico and in some of the Great Lakes.

Government Looks to Clean Up Coal

  • Energy Secretary Steven Chu says coal will have to be a part of the energy mix in the future, so the government is committing money to clean it up. (Photo courtesy of the USDOE)

President Obama’s Energy Secretary is talking about building a facility to find ways to burn coal more cleanly. Lester Graham reports:

Transcript

President Obama’s Energy Secretary is talking about building a facility to find ways to burn coal more cleanly. Lester Graham reports:

Burning coal pollutes – acid rain, toxic mercury, soot. And lately the big concern – carbon dioxide, the chief greenhouse gas contributing to global warming.

The Secretary of Energy, Steven Chu told Members of Congress, despite the concerns about pollution, we still depend on coal for half of our electricity.

“So, it’s very important that we develop the technology that captures and also that safely sequesters carbon from coal plants.”

The technology does not exist today.

Chu says three-point-four-billion dollars in government stimulus money is now available to find a way to clean up coal.

An experimental plant called Futuregen was supposed to find ways to burn coal more cleanly and do something about carbon dioxide emissions. But the Bush administration killed funding.

Secretary Chu says the Obama administration is now negotiating with Futuregen partners again.

Coal: Dirty Past, Hazy Future (Part 1)

Transcript

You are being targeted by lobbyists. The coal industry and environmentalists are both trying to influence what you think. In the first part of our series on the future of coal, Lester Graham looks at the campaigns for-and-against coal:

You probably don’t buy coal directly. But you do0 pay for it when you pay your power bill. 50% of the nation’s electricity comes from coal-burning power plants.

The problem with that is, coal pollutes.

Not as much as it used to. Some traditional pollutants have been reduced by 77% since the 1970 Clean Air Act.

Although the government forced it to reduce some some of the pollution, the coal industry brags about the progress and encouarges you to believe in the future of “clean coal.”

American Coalition for Clean Coal advertisement:

“I believe. I believe. We can be energy independent. We can continue to use our most abundant fuel cleanly and responsibly. We can and we will. Clean coal: America’s power”

Joe Lucas is the man behind that ad. He’s with the American Coalition for Clean Coal Electricity. Lucas says the meaning of the phrase “clean coal” is always evolving.

“Ah, the use of the term ‘clean coal,’ it is a term of art. Up until now it has been technology that has reduced traditional pollution emissions and increased the efficiency of power plants and going forward we’re rapidly approaching the point to where it will be technologies for capture and storage of carbon.”

But right now, no power plant captures carbon dioxide. And carbon dioxide is the main greenhouse gas contributing to climate change.

That’s why environmentalists scoff at the coal industry’s use of ‘clean coal.’

Cohen brothers advertisement:

“Clean coal harnesses the awesome power of the word ‘clean’ to make it sound like the cleanest clean there is!” (coughing)

The guy behind that ad is Brian Hardwick. He’s the spokesman for the “This is Reality” campaign.

“In reality today there is no such thing as ‘clean coal.’ There is no commercial coal plant that captures its carbon pollution not to mention the other environmental impacts that the coal industry has – from burning coal and the runoff and the extraction of coal. So, we launched an effort to try to bring out the truth about coal in response to the marketing campaign that the coal industry had so that people could come to their own conclusions about whether or not they thought coal was indeed clean.”

Clean or not, we have a lot of coal here in the U.S. It’s relatively cheap. And when pushed, a lot of environmentalists concede we’ll need to rely on coal for electricity generation for some time to come.

During last year’s Presidential campaign, candidate Barack Obama aknowledged that to people at a rally in Virginia, but indicated we need to find a way to really get to ‘clean coal.’

“Why aren’t we figuring how to sequester the carbons from coal? Clean coal technology is something that can make America energy independent.” (applause)

And President Obama has followed up on that. In the stimulus plan, 3.4 billion dollars was set aside to find ways to make coal clean.

There’s more to clean up. Sulfur dioxide, or SOx, contributes to acid rain. Nitrogen Oxides, or NOx, helps cause smog. Those have been reduced, but not eliminated. And then there’s toxic mercury and particulate matter – or soot. All of it harms the environment and public health.

President Obama’s Secretary of Energy, Steven Chu, is a big proponent of cleaner energy sources such as wind and solar. But he says we do need to find a way to use coal.

“Right now as we’re using coal it’s not clean. But, I firmly believe that we should invest very heavily on strategies that can take a large fraction of the carbon dioxide out of coal as well as the SOx the NOx, the mercury, particulate matter.”

But until that technology is in place, ‘clean coal’ is no more than what the coal industry calls an “evolving term of art.”
