Flu season is here. And this year the campus at the University of Michigan will be teeming with students wearing surgical masks. But it’s not a sign that a pandemic has hit the US. Tracy Samilton reports:
The students will be participating in a massive study to determine if wearing surgical masks really helps to cut down on the risk of getting the flu. University of Michigan researcher Arnold Monto says wearing a mask may end up having only a small effect. But he says it’s still important to know for sure.
“The reason these kinds of differences may be very important is they’re easier to implement than taking medication, so even if it has a very small effect it will end up having a major impact when we do have the inevitable pandemic.”
Students will be expected to wear surgical masks in the dorms, and they’ll be encouraged to wear them everywhere they go. The study will last for six weeks, the expected duration of the flu season.

The US EPA is reconsidering a decision to let cement plants off the hook when it comes to mercury emissions. Tests at several cement plants showed they were emitting up to ten times the mercury being disclosed. Tracy Samilton reports:
Cement plants emit mercury from both the coal they burn and from processing limestone, an ingredient of cement. But the EPA has never regulated the mercury emissions. The agency said it would be too costly for the industry. Cement manufacturers say they plan to voluntarily reduce mercury emissions over time.
But Michael Wall of the Natural Resources Defense Council says the EPA needs to exert control over the plants now.
“It would be as if we took a segment of the coal-fired power plant industry and just said ’emit mercury freely, we’re not going to do anything about it.’ That makes really bad policy and it’s really bad for our public health.”
An EPA spokesman says the agency is taking a second look at the issue, in light of stack tests showing some plants may have been grossly underestimating their mercury emissions.
Farmers who use a highly toxic pesticide will have to quickly find an alternative. That’s if the EPA sticks with a

Farmers who use a highly toxic pesticide will have to quickly find an alternative. That’s if
the EPA sticks with a decision to phase it out in four years. But some farmers say they
have no alternative. The GLRC’s Tracy Samilton reports:
Carbofuran has been widely used to combat aphids for many crops, including
soybeans, corn, tobacco and wine grapes. Many farmers have been phasing in
crops that are bred to be resistant to aphids. But agriculture industry
officials say in many instances, there’s no replacement for carbofuran.
Dale Huss of artichoke grower Ocean Mist Farms says carbofuran is the only
pesticide known that kills aphids that feed on artichokes. He says it’s
possible his industry will collapse:
“I don’t think we quite understand the full impact it’s gonna have on us. It really has us
concerned.”
Agriculture lobbyists say they’ll press the EPA to reverse the decision.
Environmental groups say the EPA did the right thing. Even small amounts
of carbofuran are lethal to birds, and it’s been blamed for the deaths of
millions of birds over the twenty years it’s been in use.
A new study adds to the debate over whether race plays a role in the placement of hazardous waste facilities. The GLRC’s Tracy Samilton reports:

A new study adds to the debate over whether race plays a role in the placement of
hazardous waste facilities. The GLRC’s Tracy Samilton reports:
Previous studies have shown that about 25 percent of the people living near
toxic waste treatment and disposal facilities are minorities, but University of Michigan
Professor Paul Mohai says that’s because researchers looked at the neighborhood in
which the facility was located. Since most of them are located close to the edge of a neighborhood, many people living just a street or two away weren’t included:
“Statistically they’d be considered no closer to the facility than someone living a thousand
miles away from it.”
Mohai says the minority percentage is closer to 43 percent when all neighborhoods in a
circle around the site are included. Researchers still have to find out if the facilities are being placed in existing minority communities, or if minorities move into them afterwards. Some environmentalists say there should be stricter regulations on toxic
waste facilities to protect all people’s health.
An Illinois Congressman says all cities should follow

An Illinois Congressman say all cities should follow Chicago’s
example and end sewage system overflows into the Great Lakes. The GLRC’s
Tracy Samilton reports:
Many cities in the Great Lakes watershed have aging sewage systems that
can’t cope with heavy rains. That can result in untreated sewage being
dumped into the Great Lakes.
Illinois Congressman Mark Kirk says Milwaukee dumps a billion gallons of
untreated sewage into Lake Michigan every year. But he says cities in Indiana
and Michigan have also dumped sewage into the Lake. Kirk has co-authored a bill
that would give all cities in a Great Lakes watershed twenty years to fix problems.
After that, they’d would face fines of 100 thousand dollars a day per incident.
“The dumping of raw fecal matter into the lake, the alarming rise in beach closings…
20 years from now, that should all be part of our past and not our future.”
In the meantime, the bill would also require cities to let the public know
when they dump sewage into the Great Lakes.
Developers are feeling encouraged by last month’s US Supreme
Court ruling on wetlands. The High Court was deciding on which wetlands deserve protection under the Clean Water Act. Some say it’s more likely
they’ll get their building permits now. Defenders of the Clean Water Act
think those high hopes are premature. The GLRC’s Tracy Samilton takes

Developers are feeling encouraged by last month’s U.S. Supreme Court
ruling on which wetlands deserve protection from development under the
Clean Water Act. Some say it’s more likely they’ll get their building
permits now. Defenders of the Clean Water Act think those high hopes are
premature. The GLRC’s Tracy Samilton takes us to the wetland where the
fight began.
Wetlands are supposed to be wet, right? Certainly wetter than this mucky little forest in
a township in Southeast Michigan, surrounded by subdivisions and strip malls. Tim Stoepker
leads the way through battalions of attacking mosquitoes. He points at a big puddle:
“Basically, you have a forested wetland here, with no diversity of plant life because you have
such a thick canopy of trees and you don’t typically have all your wetland,
typical wetland plants on the interior here because of that and because there’s no standing
water, you don’t have any of your aquatic species.”
Stoepker’s business suit trousers are getting streaked with mud but he keeps going. Next stop
is a drainage ditch at the edge of the property. It’s pretty dry:
“Now, if we were to come out here in August or July, I mean, that ditch would even be, there
would be nothing in that ditch.”
Stoepker has represented landowner Keith Carabell since the mid-1980s. Carabell was denied a permit
to build senior condos on his property. He appealed it all the way to the U.S. Supreme Court.
Stoker thinks if the nine Supreme Court Justices had seen this ditch in person, last month’s
wetlands decision would have been different. A majority would have ruled that the test for
Clean Water Act protection is permanent surface water flowing into a navigable water. Even so,
he’s optimistic. Five Justices reaffirmed that the Clean Water Act pertains only to wetlands
with a “significant nexus,” or connection, to navigable waters. He says that’s not the case
here:
“It’s hydrologically isolated from receiving and sending waters.”
But the U.S. Army Corps of Engineers sees it differently. The Corps is the agency that decides
if a wetland falls under the Clean Water Act. If so, it then issues or denies building permits.
The Corps told field officers not to talk to reporters about this or any case pending guidance
from headquarters. But a source familiar with Corps regulations says water from this wetland
does flow into the ditch. From there, it empties into a drain, which dumps into a stream and
then leads to Lake St. Clair a mile away, one of the most polluted bodies of water in the Great
Lakes region. The source says the wetland also connects to the drain on another side of the
property, and it will meet the significant nexus test when the case goes back to the lower
court.
Environmentalists like Jim Murphy of the National Wildlife Federation hope that’s true.
Murphy says small wetlands like this one need to be protected, despite their lack of surface
water and showy aquatic species:
“I think we make a mistake when we just feel that the only thing we need to protect are
charismatic wetlands, for a number of reasons. For one, even wetlands that don’t necessarily look that pretty
that pretty are oftentimes performing enormous functions, whether it be habitat, flood control,
water filtration….”
All functions that Army Corps of Engineers mentioned when it denied a permit in this case.
Murphy says the looming question now is, how will the agency react to the ruling? If they pull
back, he thinks we will lose wetlands at a much quicker pace. Or the Corps could interpret
the ruling as broadly as possible:
“We feel that if the Corps is willing to stand firm and be aggressive, that they can still
maintain protection for a good number of waters.”
Murphy thinks even at best, the Supreme Court ruling will encourage even more developers like
Keith Carabell to challenge permit denials in court. That may be true, but Tom Stoepker, the
attorney for Keith Caraball, says all that most developers want are more thoughtful decisions
from the Corps, and they want the Corps to back off from places it ought not to be. He says
that includes this wetland where anyone can see the water in it isn’t going anywhere.

Automakers say meeting the government’s new fuel efficiency standards
for light trucks will be a challenge. The final standards were issued
last week (Wednesday, March 29th). For the first time, the largest SUVs
will have to meet the standards. The GLRC’s Tracy Samilton reports:
The Alliance of Automobile Manufacturers calls the new standards the
most sweeping change to fuel economy rules in 30 years. Light trucks
include SUVS, minivans, and pickups, and account for more than half of
all new vehicles sold in the U.S.
Alliance spokesman Charles Territo says the set of rules will take weeks
for automakers to digest.
“Which happens to be about the size of a major city phone book. It’s
about 550 pages.”
Territo says one change is big SUVs like GM’s Hummer and Chevy
Suburban will no longer be excluded from fleet wide averages. And that
will probably mean more alternative technologies on the big trucks, like
hybrid and diesel engines and fuel cells. That isn’t enough for many
environmental groups, who say the changes won’t do much to reduce the
nation’s dependence on foreign oil.
Environmental groups say they’ve reached a landmark deal with auto and steel makers and the EPA that could prevent tons of mercury from getting into the environment in the future. The GLRC’s Tracy Samilton reports:

Environmental groups say they’ve reached a landmark deal with auto
and steel makers and the EPA that could prevent tons of mercury from
getting into the environment in the future. The GLRC’s Tracy Samilton
reports:
The auto industry completely phased out mercury switches in lights and
antilock breaks in 2002, but as many as 60 million of the devices could
still be on the road today.
When a car is finally scrapped and melted down at the steel mill, the
mercury is released into the air. Auto makers and steel plants have
tentatively agreed to share the cost of a national retrieval program to
remove mercury switches from vehicles before they’re recycled.
The Ecology Center was instrumental in brokering the deal. The Center
says the program could potentially reduce overall mercury pollution by
ten percent, and keep 80 tons of mercury out of the environment. The
deal is expected to be finalized within a few weeks.
A new study by an environmental group says there are high
concentrations of toxic chemicals called PBDE’s and phthalates inside many cars. The Ecology Center is calling for the chemicals to be phased out. The Great Lakes Radio Consortium’s Tracy

A new study by an environmental group says there are high
concentrations of toxic chemicals called PBDEs and phthalates inside
many cars. The Ecology Center is calling for the chemicals to be phased
out. The Great Lakes Radio Consortium’s Tracy Samilton reports:
PBDEs are used as flame retardants in auto parts, and phthalates make
plastic parts more flexible. The study found that the heat that builds up
inside a car in the sun causes the chemicals to be released, which
increases exposure to humans.
Jeff Gearhart of the Ecology Center says there are plenty of safer
alternatives and the auto industry should use them. He says there are not
many studies on the effect of the chemicals on humans, but animal
studies show that they hurt reproduction and brain development.
“We should take a precautionary approach and we think that’s the
type of approach that many people take in their own lives.”
A spokesperson for the Alliance of Automobile Manufacturers says
flame retardant PBDEs make cars safer for people in the event of a fire,
and that PBDEs and phthalates are both safe.
Some populations of gray wolves could be taken off the endangered species list. The U.S. Fish and Wildlife Service is expected to issue proposed new rules for gray wolves in the upper Great Lakes region in the next week or so. We have more from the Great Lakes Radio Consortium’s Tracy Samilton:

Some populations of grey wolves could be taken off the endangered
species list. The U.S. Fish and Wildlife Service is expected to issue
proposed new rules for gray wolves in the upper Great Lakes region in
the next week or so. We have more from the Great Lakes Radio
Consortium’s Tracy Samilton:
The growth of the grey wolf population in the Great Lakes area is good
or bad, depending on who you talk to. Wolves help control deer herds,
but they also prey on livestock.
Adrien Wydeven is with the Wisconsin Department of Natural
Resources. He says in extreme cases, states might want to let farmers
who’ve had problems shoot wolves they catch in the act of killing
livestock.
“And we could consider the possibility of a public harvest of members of
general public applying for permits to trap or hunt wolves in limited
areas.”
There will be a 90-day public comment period before the delisting of
Great Lakes wolves is adopted. It will apply mainly to wolves in
Michigan, Wisconsin, and Minnesota. Each state will also have to adopt
its own wolf management plan.
