There’s an invisible, odorless gas that kills 21,000 Americans every year. We’ve known about radon gas for a long time. But as Mark Brush reports, experts say we’re still a long way from fixing the problem:

Radon gas is found down here…

…in the basement.

Really, it’s all around us. The gas drifts out of the ground from bits of uranium ore. Normally, there’s not enough of it to cause a problem. But it can get trapped in our homes, schools, and offices. We breathe it in. And the gas can cause lung cancer. It’s the second leading cause of lung cancer next to smoking. And if you’re a smoker – you’re even more at risk.

The level of radon gas in this basement is unsafe. More than four times a safe standard set by the EPA:

So a crew of two guys is here to fix the problem.

David Aschenbrenner works for Pro-Tech Environmental in Ann Arbor, MI. He says radon gas seeps up from the ground and makes its way into the house through cracks and holes in the foundation:

“So as the air is rising through the house, the house acts as a chimney. It’s creating what we call the stack effect. And that’s what’s actually pulling the radon in.”

You can’t see it. You can’t smell it. But it’s often there.

“So with the radon piping, and the radon fan, it’s going to create a suction slightly stronger than the house breathing normally.”

They drill a hole in the basement floor – put a PVC pipe into the hole. And fan on the pipe will vent the radon gas outside.
Right now – a lot of people find out about radon when they buy or sell a house. The air is tested and if there’s a problem – it can be fixed.

Bill Field is an epidemiologist at the University of Iowa. He’s studied the health risks of exposure to radiation for decades. Field says these systems work. But even though more people know about the threat of radon gas – there are still more people exposed today than in the past:

“We’re further behind now, than we were 20 years ago with addressing the radon issue, because more homes are being built that aren’t radon resistant than are being mitigated. Each year there are tens of thousands of home that are coming on the market that will hopefully be fixed someday, but they could have been fixed when they were first built.”

Field says new homes should be built to keep radon out. He says simple changes in home construction – changes that would only add $500 in construction costs – would work. He says there should be a federal requirement to build homes this way, since radon can be a problem in every state.

There are some states, counties and cities that have radon resistant new construction written into their building codes – but more than half don’t – and even in the places that do have the code on the books – workers told us that it’s not always enforced – so it’s easy to just skip the requirement.

The National Association of Home Builders says it would oppose any federal requirements to build homes this way. They say radon should be dealt with where there are known hot spots.

There are parts of the country where radon can be bigger problem than in other areas. But it can be a problem no matter where you are. The EPA has a recommended standard for radon gas. It says that homes or offices or schools should be fixed if they have radon levels of 4 pico-curies per liter or more. But Bill Field says sixty percent of the cancers caused by radon were caused at levels below this EPA standard:

“Talk about a safe level of four pico-curies per liter is really a misnomer. It’s like saying it’s o.k. to cross the road blindfolded because there’s only one car coming instead of three. There really is no safe level of radon.”

A recent report by the President’s Cancer Panel evaluated the progress being made on cancer prevention. Exposure to radioactive radon gas is one of the areas where the experts said not enough is being done. And because the problem is getting worse – they’re recommending the government do more.

“You can test your air for radon gas by buying a test kit at your local hardware store. They cost between ten and twenty dollars.”

The Senate is releasing their version of a climate and energy bill. And as Mark Brush reports, some political insiders are saying it’s now or never for action on energy and climate:

Most environmental groups argue that the Gulf Oil spill highlights the need to pass sweeping new energy legislation. And some political observers say Democrats will never have a bigger majority in the Senate than they do now.

So now might be the time for quick passage of the Kerry-Lieberman bill.
But a few others say there’s no need to rush things.
A climate and energy bill should be good policy first.

Frank O’Donnell is with the environmental group Clean Air Watch:

“There appears to be this real race to get something done before this window closes. The best kind of public policy is not always carved out under those circumstances.”

O’Donnell says the conventional wisdom that there will be no better time than now could be wrong.

He believes there will be other opportunities to pass climate change legislation in the future.

Transcript

A big climate-change bill will be introduced in the U-S Senate next week.

Shawn Allee reports it’s expected to stop the Environmental Protection Agency from regulating greenhouse gases.

Congress worked on climate bills for more than a year, but all that time, the US Environmental Protection Agency worked on its plans.

EPA’s got authority to regulate greenhouse gas emissions on its own.

It’s doing that in case Congress waits too long or legislation’s too weak.

But some senators say to pass any, bill, they have to cut EPA’s authority.

Environmental groups say this would be a mistake.

Howard Learner is with The Environmental Law and Policy Center.

“The only justification to constrain the US EPA’s ability to do it’s job and do it well under the Clean Air Act is if Congress steps up in a comprehensive, thorough, durable, way to protect our public health and protect our environment.”

Lerner says we don’t know whether Congress’ approach to climate change will work, so the EPA should keep some power over greenhouse gas emissions … as a kind of back-stop.

The federal government is looking into whether natural gas drilling is contaminating drinking water.

Shawn Allee reports, before that study’s done, Congress might step in and tighten regulations now.

Natural gas companies pump chemicals underground to loosen up the gas and get it to the surface.

It’s called hydraulic fracturing.

There’s debate about whether the chemicals poison water that’s underground, too.

Amy Mall tracks this issue for the Natural Resources Defense Council, an advocacy group.

She says Congress might regulate this drilling through the Safe Drinking Water Act.

“What the legislation would do is make sure there’s a minimal federal floor of protection. So if your state has strong regulations, probably nothing would change, but if your state does not have strong regulations and they’re too weak, then under this legislation, your state would have to raise their standards.”

The natural gas industry points out the U-S Environmental Protection Agency already studied drilling back in 2004, and Congress decided there was no need for regulation.

Congressional critics suspect that study was biased in favor of industry.

Corn Ethanol’s Footprint

For a long time, corn growers and the corn ethanol industry have claimed their fuel is low carbon. That is, it’s lower in the greenhouse gas emissions that contribute to global warming. A second study is out which disputes that claim.Lester Graham reports:

For a long time, corn growers and the corn ethanol industry have claimed their fuel is low carbon. That is, it’s lower in the greenhouse gas emissions that contribute to global warming. Lester Graham reports… a second study is out which disputes that claim.

This study published in the journal BioScience also found corn is being used for ethanol instead of exported to other countries. Those other countries are plowing up grasslands and rainforests to plant corn for food. Less rainforest means less CO2 is being taken up by plants.

Thomas Hertel is a researcher at Purdue and lead author of the new study.

He finds ethanol from corn is not a low-carbon fuel when you include that indirect effect.

“It results in a figure which [is] not significantly lower than emissions associated with gasoline.”

But, political interests in Washington are working to extend corn ethanol subsidies which are set to expire at the end of this year.

Arctic Ocean Methane

Transcript

New research indicates the Arctic seabed is releasing methane at a rate higher than all the other oceans of the world combined. Lester Graham reports, this recent discovery raises concerns about the pace of global warming.

Under a shallow part of the Arctic Ocean, the seafloor was thought to be permanently frozen, capping vast stores of methane underneath. Researchers at the University of Alaska Fairbanks have found that frozen cap is beginning to leak large amounts of methane into the atmosphere. Natalia Shakhova is one of the leaders of a team that’s been studying the permafrost under the Arctic Ocean.

“What we’re having now, it’s up to ten-million ton[s] of methane annually escaping from this seabed. That means that permafrost does not serve as an impermeable cap to prevent these leakages any longer.”

Methane is a greenhouse gas 30 times more potent than carbon dioxide. The greatest concern about methane releases had been the permafrost on land… but this underwater release could mean climate changes could accelerate.

The Environmental Protection

three states are challenging
that finding:

The EPA says it has a duty to regulate greenhouse gasses to protect us from global warming.

The state of Texas, Virginia, and Alabama have filed legal challenges to try to stop the EPA. They say the coming regulations will be bad for the economy. And they call into question the science that EPA based its decision on.

Here’s the Texas attorney general – Greg Abbott:

“The information on which the EPA relies can neither confirm nor deny that there has been global warming, or that temperatures have risen.”

The EPA says it’s evaluated all the science available for the last ten years, and that the evidence is quote “compelling” that climate change is real – and that it’s a threat to human health and welfare.

Those three states challenging the EPA’s decision to regulate greenhouse gases are countered by sixteen other states supporting the EPA’s decision.

Environmental groups suspect tight
security at the Vancouver Olympics
has shifted an environmental risk
from Canada to the US. Shawn Allee reports:

A Canadian chemical manufacturer shipped rail cars of toxic chlorine away from Vancouver and is storing them in rural Washington State.

The company says it’s part of a long-planned renovation of the chemical plant. Environmental groups suspect the rail shipments were timed to move tanks away from the Olympics.

Fred Millar is watching this development for Friends of the Earth. Millar says terrorists have shown interest in rail cars filled with chlorine gas.

“And that’s what people are mostly worried about because just one chlorine tank car could put out a cloud over any city at a lethal level that’s 15 miles long by 4 miles wide.”

US rail companies make 100,000 shipments of chlorine and similar toxic chemicals per year. Their safety record has largely been good, but accidents have released deadly chlorine gas.

One derailment in South Carolina killed nine people.

Mixed Messages on Oil and Gas Drilling

The federal government leases public
land to oil and natural gas companies
for drilling. For at least the last
decade, energy companies have called
the shots. The Obama Administration
has indicated things are different now.
Conrad Wilson reports, there are some
inconsistencies in the Obama Administration’s
plan to reign in the industry:

Because of the recession, we’re not using as much energy. For the last
several months, there’s been a glut of oil and natural gas. Big oil and
natural gas companies saw record profits a couple of years ago – but those
profits are down now.

If you ask the energy companies, it would seem the biggest culprit is not
the economy, but the federal government.

For instance, Interior Secretary Ken Salazar is blamed for energy
companies’ falling profits. That’s because he’s criticized oil and gas
companies for acting like they have a right to drill on as much public land
as they want.

“Trade groups for the oil and gas industry repeatedly launch attacks that
have all the poison and deception of election year politics. Trade groups
for the oil and gas industry need to understand that they do not own the
nation’s public lands, tax payers do.”

That sounds like tough talk, right? And in many ways it is. There have
been some major reforms that change the way business is done between the
government and and oil and gas drillers.

But behind all this stick waving, the industry’s also getting a carrot. In
a conciliatory gesture, Salazar announced that there would be more auctions
for drilling leases this year.

The industry says it needs access to even more land. Kathleen Sgamma
directs government affairs for the Denver-based trade group Independent
Petroleum Association of Mountain States. In November, her office issued a
report criticizing the Department of Interior. Among the many concerns, was
the amount of land offered for lease.

“Our full paper looked at all of the things that the Interior Department is
doing to make it more difficult to develop American natural gas and oil on
federal lands. And one of those things is a slow down in permitting.”

But the government says a slow down in permits and leases is not causing
lower profits for oil and gas. As it is, companies are not drilling or
pumping where they already have leases – because there’s a glut of
supplies.

In Western Colorado, the Thompson Divide Coalition wants to cancel leases
and prevent drilling. Lisa Moreno heads up the alliance of ranchers,
hunters, and conservationists.

“The fact of the matter is, is the industry has a huge amount of acreage
under lease that they haven’t developed.”

Moreno says energy companies have leased about 47 million acres, but the
oil and gas companies are only using about one-third of that land right
now.

So why do oil and gas companies want more land? Even if energy companies
don’t use the lands for drilling, they’re still an important asset.

Jeremy Nichols is Climate and Energy Program Director for WildEarth
Guardians. Nichols says leases represent assets and are used to attract
investors.

“And so drilling is just part of what they do. They’re also basically land
holding companies. You know, they’re buying and selling each other left and
right. And so it’s more than just to drill or not to drill. It’s a lot
more, it’s a lot more complicated than that.”

If that’s the case, why is the government opening more leases?

Well, Jeremy Nichols thinks Interior Secretary Ken Salazar is trying to
kiss and make up.

“You know, I’ll be honest I think Salazar appearing conciliatory. But the
oil and gas industry is going to be critical no matter what Salazar does.
The oil and gas industry just doesn’t like to be regulated; they don’t like
to be told what to do. And so they’re going to complain no matter what.”

And so, more of the public’s land will be held by oil and gas drillers who
won’t be producing much until the economy recovers, prices go up and they
can make more money.
