Pesticides are designed to kill pests – and so – by their nature are toxic substances. They wouldn’t work otherwise. While that poisonous nature is useful for certain jobs… most people would probably hesitate before knowingly taking the chemicals into their bodies. But the Environmental Protection Agency is now looking at the issue of testing pesticides on humans. As bad as that may sound, the Great Lakes Radio Consortium’s Greg Dahlmann reports there are some people saying it’s what we need:

Greener Cleaners
Joseph DeSimone, founder and chairman of Micell Technologies, explains the cleaning process that clothes undergo in his Hanger’s store in Morrisville, NC.
Consumers may not realize it, but the simple act of dropping off clothes at the cleaners could end up harming the environment. For decades, dry cleaners have used a toxic solvent to clean clothes. Now there are many contaminated former dry cleaning sites across the country. But a solution to the dry cleaning problem may now be available. A new chain of cleaners is touting a “greener” system that uses a non-toxic everyday substance. The Great Lakes Radio Consortium’s Patty Murray has more:
Canada to Declare Road Salt Toxic?

Canada’s environment minister is recommending that road salt be classified as a toxic substance. The Great Lakes Radio Consortium’s Karen Kelly reports.
Approximately 5 million tons of road salt are used in Canada each winter.
And much of those salts eventually find their way into bodies of water.
The Canadian government recently completed a 5-year study of the environmental effects of road salts.
The scientists found water near some major highways contained as much salt as ocean water. And they concluded freshwater plants; fish and other organisms are being harmed. Canadian environment minister David Anderson has recommended road salt be added to Canada’s list of toxic substances.
But the government is not proposing a ban on salt. Officials are studying ways to reduce its use and improve snow removal techniques to minimize the amount of salt escaping into waterways. The public has 60 days to comment on the plan. For the Great Lakes Radio Consortium, I’m Karen Kelly.
Clean-Up Woes for Power Plant
American Electric Power is working to stop blue clouds of sulfuric acid from descending on towns near the Ohio River. Ironically, the clouds are a by-product of a 200-million dollar system installed in May to help curb smog-producing emissions from the General James M. Gavin Power Plant. The search for a solution is being watched by other power plants in the U.S. that have to comply with stricter anti-smog regulations put in place by the federal government.
Blue clouds of sulfuric acid have descended upon towns in southeastern Ohio and West Virginia more than a dozen times since May. The clouds are from smoke stacks at American Electric Power’s General James M. Gavin plant in rural Cheshire, Ohio. It’s one of the largest coal-burning power plants in North America. The company blames a new 200 million dollar pollution control system for releasing more toxic emissions. If they’re right, other Midwestern power companies may face similar troubles when trying to comply with federal clean air laws. The Great Lakes Radio Consortium’s Natalie Walston reports:

Blue clouds of sulfuric acid have descended upon towns in south-eastern Ohio and West Virginia more than a dozen times since may. The clouds are from smoke stacks at American Electric Powers General John M. Gavin plant in rural Cheshire, Ohio. It’s one of the largest coal-burning power plants in North America. The company blames a new 200-million dollar pollution control system for releasing more toxic emissions. If they’re right, other midwestern power companies may face similar troubles when trying to comply with federal clean air laws. The great lakes radio consortium’s Natalie Walston reports.
The small, rundown airport in Mt. Pleasant sits on a flat part of the hills of West Virginia.
It’s surrounded by thick trees. Its rural enough here that it’s common to see wild turkeys dashing across the runways. One summer afternoon airport manager Ben Roush looked out his window. But instead of seeing a plane land … he saw thick smoke clinging to the tops of the trees.
“It looked like, uh, exhaust out of a car or something like that. It wasn’t black smoke it was blue. Very, very visible.”
After the smoke appeared, his phone began to ring.
“The fire department down here called up here and wanted to know if we had a fire up here because it was all in these … it settled to the ground. And, it was in those trees.”
The clouds contain high concentrations of sulfuric acid. That’s not normal … even this close to a power plant that burns coal with a high sulfur content. For years, most coal-burning power plants have had pollution control devices called “scrubbers” to deal with that sulfur. The scrubbers do just what the name implies – they scrub the air clean of sulfur dioxide as well as some other pollutants. But, they don’t do a good job in removing nitrous oxide. Nitrous oxide is blamed in part for causing acid rain and smog.
Paul Chodak is manager of American Electric Power’s Optimization Group. He says AEP installed a selective catalytic reduction system … or SCR … in an effort to remove nitrous oxide. Chodak says the SCR system is a relatively new technology. And, so far, it and the scrubber aren’t working well together. That’s because they are combining to make sulfuric acid, but in a different form. And that form then gets released into the air.
“The SO3 … or sulfuric acid is in very fine droplets … sub-micron size droplets. Very, very tiny. And they’re so small that they travel through the scrubber and they’re not removed. So, the scrubber works very well on the gas in removing SO2. However, it’s not very effective in removing SO3.”
Chodak says this is all because of an effort to reduce emissions that cause acid rain and smog in eastern seaboard states. But… as AEP scrambles to stop polluting the air hundreds of miles away … people who live beneath the smoke stacks claim their health is being sacrificed. They say that in the summer, when the sulfuric acid clouds move in it’s difficult to breathe.
(natural sound of NASCAR race and drunk people carrying on)
Gallipolis is a small city five miles south of the power plant. Today there’s a small crowd of people gathered at Sunny’s bar and grille. People here will only give their first names to an out of town reporter. A man named Steve is drinking a beer at a table with his sister. He says fallout from the plant makes the paint peel off cars.
“All that acid and stuff goes on these cars. They gotta repaint the cars … so you know it’s tearin’ us up. Our bodies. And, like I say, we worry about our kids and grandkids more. We’re old enough that it’s not gonna bother us no more.”
His sister Tammy drags slowly on a cigarette as Steve talks.
When he finishes, she jumps in to say that since the blue clouds started showing up, everyone in town has become sick.
“I have health problems. I cough all the time. Allergies all the time. Allergies to something’. Runny nose. Constantly. You know, I think everyone in town has health problems that live around here.”
But AEP claims the air is cleaner than it was before the SCR system was installed. Paul Chodak says the air turned blue this summer because the sulfuric acid reacted with sunlight on hot, humid days. He says people become scared because they could actually see what they were breathing.
“The hard thing for people to understand is that what is coming out of the stack is significantly cleaner than what was coming out before. This is an improvement from a pollution control perspective. However, it has created this local phenomena that is a problem. And, AEP is moving to address that and we will solve it.”
Sulfuric acid measurements taken by the company and examined by Ohio and U.S. EPA researchers meanwhile don’t show a major sulfuric acid problem. But there are no state standards in place in Ohio for levels of gaseous sulfuric acid in the air.
Kay Gilmer of the Ohio EPA says emissions from AEP have exceeded sulfuric acid standards set by other states. However, she says people near the plant stacks aren’t in immediate danger. But she hesitates to say the air is perfectly safe to breathe.
“We didn’t have anything that would um … that we would … that we looked at that was exceptionally high. But, that was, I don’t want to say that to say we’re not concerned with the problem.”
Meanwhile, people near the plant say they’re tired of having their health jeopardized so people far away from them can breathe easier. They are working with state environmental groups to possibly fight the power plant in court.

A Canadian environmental group is claiming that nuclear waste is leaking from a dump on the shores of Lake Ontario. The Great Lakes Radio Consortium’s Karen Kelly reports.
The Port Granby nuclear waste site sits on a bluff overlooking Lake Ontario just east of Toronto. The environmental group Lake Ontario Keeper collected samples of treated wastewater from the site as well as untreated runoff. They say an independent lab found illegal levels of uranium, arsenic and other chemicals in both samples.
Norm Rubin, the group’s director of nuclear research, says it’s time the government stepped in.
“This stuff is leaking today, it’s toxic today, it’s violating the law today and we’ve waited enough decades already to see something done.”
The Cameco Corporation, which owns the dump, denies the group’s findings.
Officials at Environment Canada say they will review the report. For the Great Lakes Radio Consortium, I’m Karen Kelly.
PCBs LINKED TO MEMORY LOSS IN ADULTS

A new study finds that eating contaminated fish from the Great Lakes might have adverse effects on more people than once thought. The Great Lakes Radio Consortium’s Lester Graham reports.
For a long time health experts have recognized that small children and women of childbearing age should limit the amount of Great Lakes fish they eat. Fish contaminated with PCB’s, Polychoilnated Biphenyls, could cause developmental problems for children. This new study finds that men should also reduce their exposure to the contaminants. Susan Chantz is a researcher at the University of Illinois and the principal author of the study.
“We are seeing some impact of PCB exposure from Great Lakes fish on memory functions of adults.”
The decade long study found people who eat a lot of fish from the Great Lakes, a couple of pounds a month, generally had lower scores on memory and learning tests than those who ate less fish. For the Great Lakes Radio Consortium, this is Lester Graham.
Cold War Toxin in Drinking Water?
A toxic leftover from the Cold War is polluting soil and water at sites across the country. More than two dozen sites in the Great Lakes region could be contaminated by a chemical used in rocket fuel. The chemical was either used or stored at the sites. The Great Lakes Radio Consortium’s Lester Graham reports:
Pollution Hot Spots Get the Scoop
Polluted sediments sit at the bottom of rivers and lakes across the Great Lakes region. They can affect water quality, wildlife and human health. More than 40 highly contaminated areas in the region have been identified by the EPA’s Great Lakes Office. But so far, only about half of those sites have been cleaned up. This summer, dredging is taking place in at least three of those hot spots, all on rivers. The Great Lakes Radio Consortium’s Karen Kelly reports on the challenges of cleaning up a river bottom:

One of the rivers that flows into the Great Lakes (Lake Michigan) is
polluted so badly that it’s being treated much like a Super Fund site –an
environmental disaster. It’ll be decades before it’s cleaned up. And some
environmentalists think it might never be cleaned up properly. The Great
Lakes Radio Consortium’s Lester Graham reports:
(Sound of fish splash)
It’s late at night. The moon’s out. And the fish are flopping on the Fox
River. In downtown Green Bay, Wisconsin, Robert Hageman and a few of his
friends have been fishing. A couple of the guys are bragging about the big
fish they caught. But they’re not taking any home with them tonight.
LG: “Had any luck?” RH: “Yeah, I caught 23 fish.”
LG: “And wwhat did you do with them? RH: “Let ’em right back.” LG: “why?” RH: “Because it’s dirty. Fox River’s dirty.”
LG: “What have you heard about the Fox River?” RH: “The fish ain’t good for you. They can’t hurt you, but they ain’t good for you.
(friends in background say “PCBs, man.”) “yeah.”
LG: “What do you know about PCBs?
RH: “I don’t know nothing about it. That’s why I ain’t eatin’ them.” (all laugh)
Hageman and his friends are right when they say there are PCBs in the Fox
River. But apparently they haven’t heard that eating fish from the river
probably can hurt you in the long run. There are 60-thousand pounds of
PCBs, or poly chlorinated byphenyls, in the 39 mile run of the Fox
River. Of that, 50-thousand pounds – that’s 25 tons – is in the sediment of
the last seven mile stretch just before the river flows into Green Bay and
on into the rest of Lake Michigan. It’s that final stretch where Hageman
and his friends have been fishing.
The Environmental Protection Agency says seven paper mills along the Fox
River are the likely polluters. The EPA says PCBs were produced as a
by-product of the paper manufacturing process, and from the 1950s to the 1970s
they were dumped into the river. Now, the agency intends to make those
mills pay for cleaning up the contaminants.
Dennis Hultgren works for Appleton Papers, and is a spokesperson for a group
that represents the seven companies. Hultgren says the paper mills want to
clean up the pollution. But they don’t want to pay more than they have to.
“What we want to do is make sure that the money that we do spend
is spent wisely and it does the most environmental good for the region. And
so, we have one chance to do it right and we want to do it right the first
time.”
The paper mills have been working closely with government agencies to try to
determine where the PCBs are concentrated and how best to clean up the
pollution. Some of the companies have spent millions of dollars on tests in
the river. Just recently, Hultgren’s firm offered 40-million dollars… ten-million dollars a year for four years… for data collection and preliminary clean-up tests. The government agencies praised the decision and some environmental groups voiced their approval. But a local grassroots group, the Clean Water Action Council of Northeast Wisconsin, does not approve. Rebecca Katers is with the council and says it’s a delay tactic by the paper mill companies.
“It makes the company look generous. But, in fact, they should be doing this anyway. They should have done this ten years ago.”
Giving the money now, Katers says, only manages to delay legal action
against the company for four more years. Besides, she says, while
40-million dollars might seem like a lot of money, the estimated clean-up
could cost as much as 30 times that amount.
The Clean Water Action Council says this money and the government’s
willingness to accept it are representative of the cozy relationship the
companies seem to have with regulators. But Katers says the state and
federal agencies are forgetting about the people who live here. She
bristles when she hears the government agencies talk about how close they
are to the paper mills.
“They talked at the announcement about ongoing discussions they
have on a daily basis with the paper industries on this issue. But, they
haven’t met once face-to-face with the public. They haven’t held a public
discussion or debate on this issue.”
And it appears there won’t be many opportunities in the future. Although
the Fox River is not a Superfund site, the EPA is generally following the
process used for Superfund sites. The EPA says that means the public can
submit comments in writing. But there won’t be a lot of public discussion
until the EPA actually has a proposed plan. Katers thinks the people
should have a voice a lot earlier in the process.
But, the paper mills’ representative, Dennis Hultgren says it’s better to
let the experts work first.
“It’s complicated. For the normal citizen, it’s going to be very difficult to comment on it because they’re going to be looking at the technical merits
of their comments. And a general citizen, not having been involved, it’s going to be very difficult to have germane comments.”
The companies say they’ve been studying and testing and they’ve found
disturbing the sediment by trying to remove it proves that the PCBs should
be left in the sediment, allowed to slowly break down… a process called
natural recovery. And where there’s risk that sediment laden PCBs might
be disturbed by the river’s currents, engineered caps could be put in place.
The Clean Water Action Council says the paper mills tests were designed to
end up with that conclusion because that would be the cheaper way to deal
with the PCBs. The council wants the PCBs removed from the river and
disposed of safely… a much more expensive job.
The acting regional administrator for the USEPA, David Ullrich, says
there’ll likely be some combination of natural recovery, capping, and
removal. But, Ullrich says none of that will happen anytime soon. It’s a
big job, and it looks as though it will take up to ten years to deal with
the PCBs. And Ullrich says that’s just the beginning.
“The actual recovery of the resource, getting fish contaminant
levels down to acceptable levels and getting the PCB loadings to Green Bay
and out to Lake Michigan down, could take a longer period of time than that,
perhaps up to twenty years.”
And over that 20 year period, experts say that contamination will
naturally spread farther and farther into Green Bay and Lake Michigan.

State to Force Mercury Reductions?
Mercury emissions from more than 150 coal-burning power plants across the Great Lakes are coming under greater scrutiny this summer. Several states are considering ways to reduce those emissions. Wisconsin could become the first state in the nation to issue rules requiring large mercury reductions. The Great Lakes Radio Consortium’s Chuck Quirmbach has the story:
