Emotions Run High Over Dam Removal Questions

There are close to two hundred hydroelectric dams in Michigan, and almost half of those stopped making power a long time ago. Many of these dams are getting old and they need attention. The communities that own these dams are faced with a decision: pay to fix them, or pay to take them down. As Mark Brush reports it’s a decision that often stirs people’s emotions.

(Sound of Argo Dam)

The controversy around Argo Dam in Ann Arbor started when the State’s Dam Safety Program said there were problems were with the embankment next to the dam. The repair costs were estimated to be up to $300,000.

Laura Rubin is standing next to the dam on the Huron River. Rubin is the executive director of the Huron River Watershed Council, and she wants to take this dam out. She says taking the dam out would save the city money in the long run. She says it will also return the river to a more natural state, and would be better for fish and wildlife. Rubin says when she looks at the pond made by the dam, she doesn’t see good things.

“When I look at Argo Pond I see really a stinky, stagnant, non-oxygenated pond. It’s not really functioning. Other people look at it as, you know, this beautiful pond that they go down to. And it’s really, that’s just one of perspective, and sort of your background and your training.”

The people who like the dam accused Rubin and the Watershed Council of overhyping the problems with the dam, and with Argo Pond. The people most outspoken were the members of a local rowing club.

Rubin and others in favor of taking the dam out said the rowers could find better places to row on the Huron River, and the city could pay for the move.

Mike Taft is a coach for the Huron High School rowing team. He and many of the other rowers said the other places just wouldn’t work.

“You know my kids grew up here and this is where we spent our time. So, you can find what you want on various stretches of this river, and this is a one of a kind the way it is.”

Some environmentalists accused the rowers of digging their heels in – of not considering other options. Taft feels that accusation is unfair.

“I think this is not about the rowers. I think it’s about the Watershed Council pursuing their absolute aim here, which is to take out this dam.”

People with the Watershed Council say they do want the dam out, but they say they respect the rowers concerns.

The city of Ann Arbor put together a committee to help them with the decision. They held meetings and heard from some experts. They came to agreement on a lot of other issues about the river, but on the Argo Dam they just couldn’t agree.

Steve Yaffee is an expert on ways to manage environmental conflicts. He’s written extensively about the Spotted Owl case out west and he facilitated some of the Argo Dam meetings. He says in hindsight, he felt like the process could have been better informed. He thought it would have helped to have outside experts weigh in on the questions about science and about the alternatives for rowers.

“Because I think the rowing interests weren’t convinced that there were environmental benefits. And the environmentalists weren’t convinced that there weren’t options for the rowers. And if you’re not convinced of that, why work with that.”

Yaffee says for communities facing these big controversies it’s important for all the parties to first sit down and talk broadly about what they want for their community. He says it’s also important to have some creative thinkers at the table. People who can articulate a vision for the future and can come up with solutions.

For now, the city is planning to keep the dam. If it does, taxpayers will probably have to pay close to half a million dollars in repair and maintenance costs in the next several years, and for many cities with tight budgets money is often what ultimately drives their final decision of whether or not to keep a dam.

Some smaller companies want to keep drilling in the Gulf of Mexico. Lester Graham reports… a group called the Shallow Water Energy Security Coalition says its members’ rigs are different than the BP operation that’s polluting the Gulf.

The drillers want the Interior Secretary Ken Salazar to lift the moratorium on drilling in the shallow waters. In an article for Greenwire, Mike Soraghan reports… they’re getting support in letters from members of Congress.

“They’ve got about ten senators that have signed on and about 50 House members, including Ken Salazar’s brother who’s a member of Congress from Colorado, John Salazar.”

The drillers say there’s a big difference between BP’s Deepwater Horizon, drilling at 5000 feet… and the rigs they operate in water less than a thousand feet.

“They would argue that what you’ve heard in the past few weeks from BP officials is, you know, if this was in 200 feet of water, we’ve could have dealt with it a long time ago.”

Interior Secretary Salazar is to send the White House a report on the drilling moratorium by this Friday – the same day President Obama will be visiting Louisiana.

Scientists have engineered bacteria to seek out and destroy a chemical that pollutes drinking water. Rebecca Williams has more:

Atrazine is a pesticide used on corn, sorghum and sugar cane. It’s one of the most common chemicals polluting water supplies in the US.

Justin Gallivan is a chemist at Emory University. His team genetically engineered a type of E. coli bacteria. They programmed it to seek out atrazine in a petri dish… and destroy it.

He says right now, this engineered bacteria is too weak to survive in the wild.

“It requires quite a bit of care and feeding, as you might say, to survive even in a petri dish. So if it were placed in a more harsh environment, it is extremely likely that these types of organisms would not survive.”

He says using this kind of genetically engineered bacteria to clean up pollution is still a long way off.

Life Is Rough in the Median

Most modern city streets were designed only with traffic in mind. There was little or no attention given to green space.

Most modern city streets were designed only with traffic in mind. There was little or no attention given to green space. Over time, some cities revamped their streets adding landscaped medians to make them more attractive. But not all cities thought ahead to what it would take to keep those green areas growing. Joyce Kryszak reports, in one city the volunteers who maintain the plants in the medians – are pretty stressed out.

It’s about eight o’clock on a chilly morning. Linda Garwol is dodging two lanes of traffic to take care of the shrubs and trees planted in the City of Buffalo’s Main street medians. At least, what’s left of the greenery.

“Uh, two trees are left. Things have been replanted in some of them,” said Garwol. “It’s a nice project, but it wasn’t well-thought out, obviously.”

Gawrol says just a couple of years after the medians were planted more than 70 of the trees and shrubs have died.

The federal plan that called for the green medians in the street didn’t include money for maintenance or irrigation. The City of Buffalo says it doesn’t have the money to maintain the green strips. Garwol says that’s when she and other volunteers stepped in. But she says there simply aren’t enough of them to get the job done.

“It is tough work. It’s bending, it’s picking up garbage, it’s weeding. So, it’s not easy to get volunteers, especially at this time of the morning. This is the big problem. To avoid the traffic you have to be up early,” said Garwol.

But it turned out that weeding was the least of their problems. Late last summer, it stopped raining. And, the strips are too narrow, the dirt too poor to retain enough water. And… there’s no irrigation system. Unless you count Sister Jeremy Midura. The Catholic nun started braving the traffic to save the wilting landscape in front of her church. Every week day morning at dawn, she tugs five gallon buckets of water between the racing cars.

“They recognize me as the crazy median woman,” said Midura.

“How many of buckets of water do you have to take out there?” reporter. “Well, we use about 12-14 buckets on the larger median across from Catalician Center and our church. Then about ten buckets over by our school area,” said Midura.

But the traffic-dodging nun couldn’t carry enough water for all the two-mile stretch of thirsty plants. By fall, the city finally sent some tanker trucks to water the medians twice a week.

And still trees and shrubs died.

This appears to be a case of bad planning. Experts say anything planted in small medians need to be drought and salt resistant. They have to be planted in the right kind of soil. And irrigation systems should be part of the plan. Otherwise, experts say cities are just throwing away their investment. We wanted to ask the City of Buffalo about that, but the city did not return our calls.

“Right now, we’re walking along what was a Olmstedian bridle-path…”

Frederick Law Olmsted was a 19th century landscape architect. Brian Dold works for the Olmsted Conservancy. Dold says Olmsted designed the boulevard to be tree and plant friendly. It’s thirty feet wide. Two rows of elms arch over the broad, grassy lawn.

Dold says there’s more than enough soil for roots to spread wide and deep and survive droughts. He says, unfortunately, that’s not the case in many urban landscapes today.

“And that really creates an environment where you’re asking too much of a common plant to survive and do well in,” said Dold.

But cities such as Buffalo are learning from their mistakes. The medians now being added down the rest of Main Street will have irrigation systems. A special adaptive soil is being used. And… there’s a good chance the new plantings will survive in the green strip between the lanes of traffic.

Oil from the big spill in the Gulf of Mexico is starting to turn up in places people did not expect.
That’s making it tough for cleanup crews to stay one step ahead of the oil.
Shawn Allee reports some scientists hope supercomputers might help.

Scientists want to put together a 3D picture of what the gulf oil plume looks like, and they’re using new computer code and supercomputers to do it.

The numbers are getting crunched at Argonne national laboratory outside Chicago.
Pete Beckman runs the computing center there.

He says satellites and water samples give us some information, but we could really use a more complete picture.

“If we know for example that, because of eddies and currents, that things will accumulate at a particular map location, well, that’s where you would send the booms to soak up the oil. If you can concentrate your resources in one place, you’re much more effective.”

Beckman says even with some of the fastest computers in the world, the model of the spill could take days to finish.

Keeping Your Lawn From Bugging You

  • There's a movement to stop using pesticides and sprays on your lawn. (Photo courtesy of Horia Varlan CC-BY)

A lot of us have a love-hate relationship with our lawns. We love them when they’re lush. We hate them when they’re full of dandelions and dead patches. It’s easy to have someone come out and spray pesticides to take care of weeds and bugs. But some people say it’s not necessary and could do more harm than good. Rebecca Williams reports:

A lot of us have a love-hate relationship with our lawns. We love them when they’re lush. We hate them when they’re full of dandelions and
dead patches. It’s easy to have someone come out and spray pesticides to take care of weeds and bugs. But some people say it’s not necessary and could
do more harm than good. Rebecca Williams reports:

So, you might be using pesticides on your lawn right now. And of
course, the pesticide industry says that’s okay.

The industry says the chemicals are safe to use on the lawn if you use
them correctly.

Alan James is president of Responsible Industry for a Sound
Environment, or RISE. It’s a trade group for pesticide companies.

“If individuals or professional applicators read the labels and follow
labels, the likelihood of misuse of pesticides is virtually zero because the
labels provide all the information a consumer or professional needs to
apply products both efficiently and safely.”

But the problem is, not everybody reads the label.

Alan James says if you’re hiring someone to spray your lawn you should
make sure they’re certified and insured. You should also take your kids’
and pet’s toys off the lawn before they spray.

But a lot of people say there’s no point in using chemicals just to make
your lawn look good.

Jay Feldman is with the group Beyond Pesticides. He says of the 30
most common lawn pesticides, most of them are suspected by the
Environmental Protection Agency to cause cancer, birth defects or other health problems.

“There’s a range of adverse effects that are indicated as a part of the
pesticide registration program at EPA. EPA knows this information.
Why not remove pesticides from the equation, especially in light of the
fact that they’re not really necessary?”

There’s a movement to stop using pesticides in North America. Both
Ontario and Quebec have banned the sale and cosmetic use of
pesticides.

So if you’re not going to use pesticides, what do you do?

That’s a question Kevin Frank gets a lot. He’s an extension agent at
Michigan State University and an expert on lawns.

“I love to mow my lawn on the weekends because nobody can call me on
the phone or email me with questions.”

He’s been showing me green, healthy test plots of grass and some that
look sad and neglected. The scientists here have been working to find
ways to have good-looking lawns without a lot of chemicals.

Back in his office, Kevin Frank says he tells people they shouldn’t be
afraid to experiment.

“Do you have it in you to let it go for one season and see what happens?
And it could be ugly, so you’ve got to be prepared for that!”

He says a healthy, dense lawn is actually really good at fighting off
weeds and pests all on its own. So, how do you get a healthy, dense lawn
without a lot of chemicals? Frank says it might take a couple years to get
there. And it means going against conventional lawn advice.

“We’ve done a great deal of research here at Michigan State that runs
contrary to what I call ‘turf dogma’. You know: water deeply and
infrequently – and we’ve shown if you do it on a more frequent basis you
end up with a healthier plan overall.”

He recommends watering lightly – just 10 minutes – every day instead
of soaking the lawn once a week. Frank says it’s also good to fertilize
twice a year, use a mulch mower, and mow high instead of giving the
grass a buzz cut.

He says that could make your lawn so healthy, it might mean you won’t
need to spray or hire someone to spray your lawn.

He says the biggest adjustment in reducing pesticide use is managing
your expectations, and deciding how many weeds and bugs you can live
with.

Next week Congress will hold what’s likely to be the first of many hearings on the drilling rig explosion and oil spill in the Gulf of Mexico. Lester Graham reports this is just the latest Congressional investigation into BP’s operations.

Congressman Bart Stupak chairs the House Energy and Commerce Subcommittee on Oversight and Investigations. He says you can add this oil spill in the Gulf to several oil spills on Alaska’s North Slope and the refinery explosion that killed 15 people in Texas City in 2005. He says earlier this year he fired off a letter about billions of dollars in budget cuts BP just recently made.

“We wanted to make sure these cuts don’t negatively affect the safety of the workers or the environment. I mean, we put that in writing to them in January. And when I heard about the blow-out and the fire down there and the accident, they didn’t have to tell me the company that was bitten by this. I just figured it was BP.”

Stupak’s subcommittee will be questioning BP officials, the drilling rig operators, TransOcean, and Halliburton which did maintenance work on the rig.

Weather Modification Making It Rain

  • The cloud seeding generator sprays heated silver iodide into the air-which then acts like a magnet, attaching to ice particles until snow forms.(Photo courtesy of Christina Aanestad)

We need a lot of water. We use it to grow food, wash our cars and even make electricity at hydro-dams. But in some areas there might not be enough water. The federal government estimates places in 36 states might experience drought conditions by 2013.

So, scientists and power companies are looking at manipulating the weather to create more water. And, as Christina Aanestad reports the practice, called weather modification, is more common than you might think:

We need a lot of water. We use it to grow food, wash our cars and even make electricity at hydro-dams. But in some areas there might not be enough water. The federal government estimates places in 36 states might experience drought conditions by 2013.

So, scientists and power companies are looking at manipulating the weather to create more water. And, as Christina Aanestad reports the practice, called weather modification, is more common than you might think.

“A mile and a half to go–we should see the cloud seeder.”

I’m traveling through the rugged terrain of Burney Falls, in northern California with Paul Moreno. He’s a spokesperson for Pacific Gas and Electric, one of the nation’s largest power companies and it wants to modify the weather in this remote area- it’s a process called cloud seeding.

“There it is……”

Energy companies, water districts and the federal government have conducted weather modification since the 1950’s. Today, it occurs in about a dozen states in the US-mostly the West and Midwest.

Moreno points to a large metal box.

“were’ looking at a cloud seeding generator that is off the ground about 12 feet on a steel platform and inside the cabinet is a tank that contains the silver iodide solution. The silver iodide solution is sprayed kind of atomized, like a perfume atomizer.”

This is how it works: the generator sprays heated silver iodide into the air-which then acts like a magnet, attaching to ice particles until snow forms. The purpose? More snow means more water and, more water means more power for Pacific Gas and Electric’s hydropower project.

At least… that’s the theory.

“It’s never been proven to actually work.”

Matt Ryan is a 25-year weather consultant.

“The idea that you can drug the sky into dropping more rain onto you is part of the problem in and of itself. Silver iodide which is the drug of choice throughout the cloud-seeding industry is a class-C toxic non-soluble inorganic chemical. When they say that it is Class C-You can’t flush this down the drain…it’s toxic.”

But not everyone thinks it’s a serious threat. Brant Foote heads the Research Applications Lab at the National Center for Atmospheric Research, in Colorado. He’s studied cloud seeding for decades.

“In general what we’ve shown is that health hazards of cloud seeding is negligible.”

But, Foote seems less certain about whether cloud seeding actually works.

“It’s been a tough nut to crack. There have been a lot of attempts to evaluate cloud seeding and more often than not with inclusive results, rather than with either negative or positive.”

Whether it works or not is beside the point to some. They just don’t like the idea. Mark Franco is headman for the Winnemum Wintu Tribe in Northern California. He doesn’t think people should be playing around with nature. He says instead of trying to artificially make precipitation, maybe we should be putting more effort into conserving water.

“One of the things people forget: when you’re running out of water, don’t use as much. Use water efficiently, people need take responsibility for the usage and waste of water.”

But, despite concerns about whether cloud seeding is a good idea… or whether it even works… some states support the science with millions of taxpayer dollars. And, utilities like Pacific Gas and Electric spend millions of ratepayer dollars on cloud seeding projects in the US.

Rainwater Toilets Caught in Red Tape

Sometimes we hear complaints that environmental regulations stop us from doing what we want with our property.
Environmentalists say there’s one issue where doing the green thing can attract a bunch of red tape.

Shawn Allee reports it’s about using rain water to flush our toilets.

This story starts at a forest preserve in Lake County, Illinois, north of Chicago.

Jill Stites is here to show off the forest preserve’s custom-built welcome center.

Stites: This building was built for people to come out and see what people could do in their own homes.

In other words, the idea was, we could do it, it didn’t break the bank entirely, here’s something you might want to try, that sort of thing?
Stites: yes, you can really do green building in a responsible way.

Stites shows me how the building collects rain water from the roof.
That keeps rain out of sewers.
That way, the local waste-water treatment plant doesn’t waste chemicals and electricity to purify rainwater.
After all, rainwater’s already clean and you can store it in cisterns, like this one.

Stites: It collects water off of the roof and goes directly in there. and there’s a spout on the bottom of the cistern that you can hook up a hose to and water your flowers with.

But Stites’ building wanted bigger bragging rights.
They wanted to prove people can collect rain water for more than just flowers.
You can use it for something more urgent: flushing your toilet.

Stites: you don’t need drinking water to flush your toilet. you’re saving the water from going to the storm sewers to be treated to come back as drinking water when that’s not necessary.

There was trouble, though.
The forest preserve district couldn’t get a permit to use rain water in the toilets.

It wanted a connection to city water, as a kind of backup.

But the state worried untreated rain water might somehow contaminate the city’s drinking water.

It took years to get special permission.

Stites: We’re bragging about it. It’s been in the paper about the possibility of it happening and we’re hoping by summer that it’s going to be a fact.

Well, the Lake County Forest Preserve District got its permit, but it won’t let the issue die.
It wants average homeowners to have an easier time, so do environmental groups.

Ellis: It’s a time-consuming process. If we’re going to have more individuals and business doing this, it’s just going to become a bureacratice mess if they have to get variances every time.

This is Josh Ellis.
He’s with the Metropolitan Planning Council in Chicago.
He wants rain collection for toilets to go mainstream in Illinois, but state law needs an update.

Ellis: It would just be a matter of course instead of a special process just to run your toilets a little bit differently.

He says engineers and plumbers have proven rain water collection can work for toilets, safely.

Ellis: We just need to upgrade the plumbing code and I think it will be smooth sailing from there.

Maybe smooth sailing … if you have the cash.
I ask an industry leader for specifics.
His name’s Joe Wheeler, and he’s with the American Rainwater Catchment Systems Association.
The U-S Environmental Protection Agency estimates, each year the average household spends just 200 dollars on water.
Wheeler says, for a rain water collection system …

Wheeler: You could do a really good job for about 4500 to 15,000 dollars. Every house is different. We’re not talking McDonald’s Big Macs here, we’re talking every one of them is a unique situation.

Wheeler says overseas, using rainwater for toilets is common and cheap.
Take Germany, for example.

Wheeler: Basically when you go into a home, you don’t know … you can’t tell the difference.

But Wheeler says German homes and businesses get pushed toward rain harvesting.

Wheeler: People would actually get a rebate on their waste water and that gave the whole market in Germany a critical mass.

It doesn’t work like that here, so in the U-S, rain harvesting for toilets is nowhere near critical mass.

Putting Brakes on Brake Pad Material

States are considering laws to phase out a material used in brake pads on cars and trucks. Lester Graham reports… it’s contributing to water pollution that’s affecting fish.

There’s a fair amount of copper in brake pads. Every time you put on the brakes… some of brake pad and the copper in it is worn off. It ends up on the pavement and eventually is washed into a stream or lake. That’s been causing some concern in the state of Washington where too much copper is hurting the salmon. A new state law bans heavy metals in brakes and requires phasing out copper.
Curt Augustine is with the Alliance of Automobile Manufacturers. He says they worked with lawmakers and environmentalists to come up with the plan. Other states might adopt it.

“Bills have been introduced in California and Rhode Island and likely similar bills will end up in some of the Great Lakes and Chesapeake Bay states.”

The Washington law calls for brakes to contain no more than five percent copper by 2021 and then consider using even less in later years.
