More than a year ago – when an earthen wall broke at a power plant in Tennessee, 500-million gallons of toxic coal ash and water were spilled. If you compare it to other environmental tragedies – it was 50 times bigger than the Exxon Valdez spill. Half of the coal ash spill’s been cleaned up, but crews are still working to get the rest of it. And as Tanya Ott reports there are concerns about a new plan to deal with the ash:

More than a year ago – when an earthen wall broke at a power plant in Tennessee – 500-million gallons of toxic coal ash and water were spilled. If you compare it to other environmental tragedies – it was 50 times bigger than the Exxon Valdez spill. Half of the coal ash spill’s been cleaned up, but crews are still working to get the rest of it. And as Tanya Ott reports there are concerns about a new plan to deal with the ash:

The plan comes from the US Environmental Protection Agency. Clean-up crews would scoop up the ash and put it in the same pit it came from… but the pit’s been reinforced with concrete. What the plan doesn’t call for, though, is a liner to make sure no metals leach into groundwater. Tennessee law and even the EPA’s new proposed coal ash rules require liners.

Craig Zeller is the project manager for the EPA. He says because this pit isn’t new – or expanding – it doesn’t have to comply with the rules. Plus, he says, water testing in the area shows there’s no problem with leaching.

“If, in the future it does show that we need to add a groundwater mediation piece to this, we will!”

Adding a liner after-the-fact could be difficult and expensive. The new clean-up project will take four years and cost 268-million dollars.

The government missed a deadline to
declare whether a chemical in food
packaging is safe. Shawn Allee reports critics are growing
tired of the delay:

The chemical is Bisphenol-A, or BPA. It’s found in some plastic food packaging and the inside of most tin-cans.

The US Food and Drug Administration is reviewing whether BPA causes developmental diseases and some cancers. The agency missed a deadline of November 30th, and some groups are getting impatient.

Sarah Jennsen is with the Natural Resources Defense Council. She says while the Food and Drug Administration deliberates, more studies are coming out against BPA.

“We’ve had studies now published that show toddlers exposed to BPA behave diffrently from toddlers who are not exposed, and so this human research which is being published is very concerning because it’s replicating what we’ve already seen in the animal studies.

The Food and Drug Administration won’t say which studies it’s including in its scientific review of BPA or when it will finish.

A study has found links between a chemical used in some plastics and aggressive behavior in girls. Lester Graham reports on the latest research on BPA:

BPA, Bisphenol-A, is used in a lot of plastic products including plastic dental fillings, carbon-less paper receipts and most canned food linings.

Researchers tested 249 pregnant women for their exposure to BPA and then followed-up after they gave birth.

Joe Braun is one of the researchers at the University of North Carolina-Chapel Hill. Braun says the mothers were given a lengthy questionnaire on the children’s behavior when they turned two.

“And what we found is that the exposure to BPA, or bisphenol-A, in pregnancy was associated with behaviors like aggression or hyperactivity. And this association was strongest in girls and we really didn’t even observe an association in boys.”

The study was published in the journal Environmental Health Perspectives.

Braun says they’ll continue to follow the children to see if the aggressive behavior is lasting.

Kicking a Chemical Out of Cans

More than a hundred studies have linked a chemical in plastic to health problems. Things like breast cancer, prostate cancer, diabetes, and early puberty. This chemical, bisphenol-A or BPA, is used to coat the inside of baby formula cans and almost all food and soda cans. Rebecca Williams visits one company that’s found a safer can:

More than a hundred studies have linked a chemical in plastic to health problems. Things like breast cancer, prostate cancer, diabetes, and early puberty. This chemical, bisphenol-A or BPA, is used to coat the inside of baby formula cans and almost all food and soda cans. Rebecca Williams visits one company that’s found a safer can:

(sound of forklift backing up, pumpkin seeds pouring out of roaster)

It’s pumpkin seed roasting day at Eden Foods. It’s a natural foods company based in Michigan. It sells things like rice, canned beans, and all kinds of packaged fruits and sauces.

Michael Potter is the company’s president. More than a decade ago, he came across some news reports out of Europe.

“And I learned all the can linings in the USA were lined with this lining that leaches BPA into foods from the can.”

That got him thinking, and researching. Then he started badgering his can manufacturers.

“We virtually begged them to provide us an alternative. We persisted in hounding them and eventually the Ball Corporation said they’d make a can with an old lining they used to make.”

The lining’s made from a plant resin instead of the epoxy resin with BPA. The thing was, it would cost Eden Foods 14 percent more – that’s about 2 cents a can.

But Michael Potter says he had to make the switch.

“We’re selling this not only to people that we don’t know, in the market, we’re feeding it to our children, our grandchildren and ourselves – we didn’t want to eat bisphenol A.”

But there was one problem. He couldn’t make the switch for canned tomatoes.

Tomatoes are acidic, and they can eat through the plant resin can lining. That could lead to bacteria or rust getting into the food.

“There is no alternative for high acid foods other than bisphenol-A lining at this point. We are urging, nudging, demanding a bisphenol-A free alternative. And we’re optimistic we’ll end up with one.”

But the metal can industry says those alternatives just don’t exist right now.

John Rost is with the North American Metal Packaging Alliance. He says the industry is trying to find new materials. But he says shoppers shouldn’t worry about eating canned food.

“The levels of BPA that are coming from epoxy can linings are exceedingly low. We’re talking low parts per billion. That level has been deemed safe by the European Food Safety Authority, Health Canada and the US FDA.”

That’s true, but Health Canada has declared BPA toxic. It’s making moves to limit its use.

A number of independent scientists debate that there’s any safe level of BPA.

Maricel Maffini studies BPA at Tufts University School of Medicine. She says they’ve seen harmful effects on lab animals at the same very low levels of BPA that are leaching into our food from cans.

She says that’s because BPA acts like the hormone estrogen.

“You just need a tiny little signal to trigger an effect. So I think it’s unfair to say there is a safe dose because as scientists we cannot say that yet. We have not found a dose that is low enough where we don’t see effects.”

She says babies and kids are the most at risk. She says BPA has caused lasting damage in lab animals when the animals were exposed to the chemical both before and after birth.

“I think we should be concerned, I think we should limit our consumption of canned foods especially if you are pregnant or if you have babies.”

It’s possible that US can makers will be forced to stop using BPA. Leaders in Congress have introduced bills that could soon ban BPA in all food and beverage containers.

Bpa in Your Body

A chemical found in plastic might be present in people’s bodies more than previously thought. A number of previous studies suggest that even at very low levels bisphenol-A, or BPA, could be linked to health problems. They range from prostate and breast cancer to early puberty in kids.

A chemical found in plastic might be present in people’s bodies more than previously thought. A number of previous studies suggest that even at very low levels bisphenol-A, or BPA, could be linked to health problems. They range from prostate and breast cancer to early puberty in kids. Rebecca Williams reports:

Scientists thought our main exposure to BPA was through food because of plastic linings in cans and other containers. They also thought BPA didn’t stay in our bodies very long.

But in this new study, researchers found that people who fasted for 24 hours still had levels of BPA close to the same as people who’d just eaten.

So they think we might be exposed to BPA some other way. Maybe water – some plastic water pipes contain BPA. Or, BPA is staying in our bodies for longer than people thought. Or both.

Dr. Rick Stahlhut is the lead author of the study in Environmental Health Perspectives. He says there are some ways to reduce your exposure from food.

“You’d probably have to get food that was mostly fresh and cook it yourself and try not to use polycarbonate plastic to store food.”

And he says use containers and bottles that don’t contain BPA.
