A new report from the group Environment Michigan says 115 inland lakes and rivers in the state have advisories for mercury pollution. Eating contaminated fish is the main way people are exposed to mercury.

Jessica Surma is with Environment Michigan. She says children are especially at risk for adverse health effects from mercury exposure.

“These can include lowered IQs, developmental disabilities and problems with motor control.”

The Environmental Protection Agency says electric utilities are by far the largest manmade sources of mercury emissions in the U.S. The EPA is planning to regulate mercury from power plants – for the first time ever.

John Austerberry is with DTE Energy.

“We agree with the goal of those regulations, but we are concerned that the federal rules will not provide sufficient time for the utilities to plan and install control systems.”

He says the company doesn’t know yet how much any new mercury control systems might cost or how much of that cost they might pass on to customers.

Researchers at Indiana University have discovered two new kinds of flame retardant chemicals showing up in the air around the Great Lakes. These chemicals are added to polyurethane foam to help keep furniture and baby products from catching on fire.

They’re replacing other flame retardants called PBDEs that have been linked to neurological and developmental defects, and fertility and reproductive problems.

These newer chemicals are called brominated benzylates and brominated phthalates.

Ron Hites is an author of the study. His team found the chemicals in air samples from six sites around the Great Lakes... from Chicago to the remote Eagle Harbor in the Upper Peninsula. But he says it’s not clear yet what this might mean.

“We have very limited toxicology and virtually no information on ecological effects.”

Hites says one study suggests these chemicals can cause DNA damage in fish.

He says the concentrations of the chemicals in the atmosphere appear to be doubling every year or two in the Great Lakes region.

So how do you know if a product has flame retardants in it?

Experts say there's no way to know just by looking at a couch or car seat or baby changing pad whether it has flame retardant chemicals in it, but they say generally, if it has polyurethane foam and a label indicating it meets CA TB 117 (a California flammability standard that companies often meet by adding flame retardant chemicals), there's a very high probability the product contains flame retardants.

In a publication from the National Institutes of Health, Heather Stapleton, PhD says:

"I don't think we know much at all about the potential human health effects from exposure to these chemicals. What we do know is that infants are likely receiving more exposure to these chemicals than adults. Therefore, more research is warranted to determine if this exposure is leading to any adverse health effects."

The American Chemistry Council stands by the use of flame retardants.

But some scientists say these chemicals pose unnecessary risks.  The Green Science Policy Institute says many types of halogenated flame retardant chemicals are "persistent, bio-accumulative and toxic." The group has put out some guidelines for consumers.

Kennecott Eagle Minerals

Four groups are planning to appeal a recent court ruling that cleared the way for Kennecott Eagle Minerals Co. to go ahead with mining operations in the U.P., the Associated Press reports:

The opposition coalition was filing paperwork Monday asking the Michigan Court of Appeals to overturn a decision last month by Circuit Judge Paula Manderfield. She ruled that the Michigan Department of Environmental Quality acted properly by issuing Kennecott a permit for the project in northwestern Marquette County.

Last month, Michigan Radio's Rebecca Williams explored some of the possible environmental effects the mine could create and spoke with  opponents and representatives of the mining company:

Michelle Halley is an attorney for the National Wildlife Federation. It’s one of the groups that challenged (the initial) permit. She says they’re concerned about the type of mining that will happen in the Eagle Mine. It’s sometimes called sulfide mining.

“The rock at Eagle is extremely acid producing, very high in sulfides and so once that rock is exposed to air and water, there’s really no debate it will begin producing acid.”

That acid is sulfuric acid. According to the Environmental Protection Agency... that acid can cause heavy metals to leach from rocks. The resulting fluid can be highly toxic to people and wildlife.

This is called acid mine drainage. On its website, Kennecott Eagle Minerals Company says there is a risk that it can happen. But the company says it’s taking a number of steps to reduce that risk.

Matt Johnson is with Kennecott. He says the company will use a state of the art water treatment plant to purify the mine water using reverse osmosis.

“The entire mine site is designed to control water with water protection in mind. Which is why it’s the company’s commitment not to discharge any water back into the environment until it meets safe drinking quality water (sic) standards.”

And he says the state is also requiring them to do that.

Michigan Radio's Mark Brush followed up with an examination of what the state might gain financially from the project.

Officials from the Michigan Department of Natural Resources say the harvest from the 2011 firearm deer season "appears to have increased slightly compared to the 2010 season."

From a Michigan DNR press release:

Experiences can differ widely even within regions, but DNR biologists estimate the harvest compared to 2010 was unchanged to up perhaps 10 percent across the Upper Peninsula, likely increased in the Northern Lower Peninsula by as much as 10 percent, and the southern Lower Peninsula appeared down 5 to 10 percent.

The statement said deer populations in the Upper Peninsula and the Northern Lower Peninsula are not as abundant as they were in the 1990's, but they seem to be increasing.

Michigan lawmakers are debating this week how to help low-income families pay their heating bills. It’s turned into an urgent problem because of federal budget cuts... and a court decision that has tied up millions of dollars. Here’s how it works: there’s a program called the Low-Income Energy Efficiency Fund. If you get your power from DTE or Consumers Energy, you pay into that fund when you pay your energy bills... somewhere between one and two dollars a month. There’s been about $90 million dollars in that fund annually.

There’s a shakeup in managing Michigan’s forests.

A new advisory council is heavily weighted with voices from the timber industry, and there will be more emphasis on developing forest products to boost the state’s economy.

Governor Rick Snyder says there’s a lot of potential to use natural resources to bring in more revenue.

The head of the Department of Natural Resources has just appointed a new ten member forest advisory council. Eight of the ten members are connected to the timber industry.

The new council will focus on developing logging and lumber, pulp and paper, and biofuels. An existing forest management advisory group includes other interests such as wildlife, recreation and conservation as well as logging.

Marvin Roberson with the Sierra Club says those other voices largely will be gone from the new council.

“I think this is going to mean a lack of management for natural conservation values and an increase in management for timber-only values,” said Roberson.

The DNR also is reorganizing its forestry division so that come January it will no longer deal with oil, gas and minerals or recreation on state forestland.

Black bears have been doing well in northern Michigan for a while. There are somewhere between 12,000 and 15,000 bears in the state, mostly in the U.P. and the northern lower peninsula, but in recent years, bears have been on the move.

Some people are already getting a little closer to bears than they’d like to.

“There’s one coming up to inspect...”

Terry Klein is a commercial beekeeper and he’s checking on the hives in his backyard.

“These are in good shape if they’re that far down and there’s that much honey on them,” said Klein.

He lives in St. Charles. It’s about 20 miles southwest of Saginaw.

“This spring is the most recent fun we had with the bear, if you want to call it that.”

Klein had 20 hives set up near the Saginaw-Midland county line. Only two of them survived the winter. And those last two hives were the ones the bear decided to eat. He left behind a calling card.

“There was one very definite paw print in one of the frames that had fallen or got knocked out of the hive, and there were several other frames that you could see claw marks.”

Bears do love honey, but they also love to eat the bee larvae. So they can devour the entire hive.

Black bears are not just wandering into the Saginaw area. They’ve been showing up all over southern Michigan.


The sport fishery has been on the rocks in Lake Huron for quite some time.

We first reported on the collapse in Lake Huron back in 2006.

That's when Jim Johnson with the Michigan Department of Natural Resources Alpena Fisheries Research Station explained to Lester Graham what was going on:

"There was a huge decline in the amount of nutrients available to zooplankton and phytoplankton in the middle of Lake Huron. These are the basic nutrient bits that fish eat. And it appears now to most of us in the scientific community that a large portion of the nutrients that used enter Lake Huron are now being trapped by zebra and quagga mussels and not finding their way to alewives and other prey fish."

Now we hear news that the state plans to cut salmon stocking in Lake Huron.

From the Associated Press:

Michigan plans a sharp cutback in Chinook stocking in Lake Huron next year, further evidence of the collapse of the lake's salmon fishery.

The state Department of Natural Resources said Friday it will place 693,000 spring Chinook fingerlings in Lake Huron in 2012. That's down from the nearly 1.5 million fed to the lake this year.

Acting DNR fisheries chief Jim Dexter says recreational harvest of Chinook has all but disappeared in the southern two-thirds of Lake Huron. The lake's only productive recreational fishery is in the northern section, where salmon are proving able to reproduce on their own.

Fish biologists blame Huron's Chinook drop-off on the unraveling of the food chain likely caused by invasive zebra and quagga mussels, which have gobbled up plankton needed by forage fish.

When Ernie Runions took the job as maintenance manager at the Senior Citizens Housing Center in Louisville, New York, he didn’t realize how much time he’d be spending in this small room. The water room. It’s filled with water tanks and filters. Runions says the equipment cost about $25,000 and the price tag keeps rising.

“It’s in terrible shape. It keeps falling apart. Every time we fix it, it’s $5,000, $3,000. This place is right in the hole because of that.”

We fill a bucket with the nursing home’s water – before it’s gone through the extensive filtering.

It smells bad, like eggs and iron. It’s got a blackish tint, and it’s got black particles floating in it.

Runions says even after the filtering, the elderly residents don’t want to drink it. It’s high in sodium, which can be bad for their health. And it smells like chlorine, which Runions uses to kill bacteria.

“And they complain. They say the chlorine is making me itch, all the extra chlorine. I’ve got red blotches all over my body, and my doctor says it’s the chlorine from the building.”

Town leaders say that until a few years ago, everyone used well water. And most people had some kind of problem with it. Nearly half the wells tested had coliform bacteria contamination – some suspected sewage was seeping into the wells.

Kennecott Eagle Minerals

Drilling continues in Michigan's Upper Peninsula for potentially valuable ore deposits after a judge turned down a request from environmental groups to stop the mine's development.

Kennecott Eagle Minerals is drilling 25 miles northwest of Marquette primarily for nickel and copper, but palladium, gold, and silver could also turn up in the deposit.

Kennecott, a subsidiary of the London-based Rio Tinto Group, began drilling in September.

The ore deposit the company is after is about a mile away from the mine's opening (and about 1,000 to 1,500 feet underground). They're not expected to reach the deposit until sometime in 2013.

Around 50 percent of the deposit is under state-owned land, so it belongs to the collective "we" - the citizens of Michigan.

So what are we getting in return?

For ten years, Kennecott Eagle Minerals Company has been pushing to mine nickel and copper near Marquette. The company started underground blasting of the mine in September.

The Department of Environmental Quality issued permits for the mine in 2007. But several of those permits have been challenged in court.

A circuit court judge in Ingham County recently upheld the mining permit.

Michelle Halley is an attorney for the National Wildlife Federation. It’s one of the groups that challenged that permit. She says they’re concerned about the type of mining that will happen in the Eagle Mine. It’s sometimes called sulfide mining.

“The rock at Eagle is extremely acid producing, very high in sulfides and so once that rock is exposed to air and water, there’s really no debate it will begin producing acid.”

Michigan's State Park System

Nov 28, 2011

The Michigan State Park System won the gold medal award this year for the top state park system in the nation. People use the parks for swimming and boating during the summer, and hunting and downhill skiing during the winter, among a host of other activities.  We wanted to find out more about how the parks system affects our lives.  So, as part of our series, "What's Working," we called Ron Olson, the Chief of Parks and Recreation.

Mark Brush / Michigan Radio

The new system to help fund Michigan state parks was a success in its first year.

Before the "Recreation Passport" system was put in place, park visitors had to buy annual or daily window stickers.

Now, people can get access to the parks by paying an extra $10 when registering their motor vehicle at the Michigan Secretary of State (window stickers and daily passes are still an option if you didn't pay extra at the Secretary of State).

The $10 annual fee is a lot less than the $24 people used to pay for an annual window sticker, but because more people participated, more money was raised.

From the MDNR:

In 2011, the program's first year, the DNR set a goal of 24.3 percent participation by Michigan motorists. Final tallies for the first year show that the goal was met and exceeded, with 24.7 percent of Michigan motorists checking "Yes" to support the Recreation Passport when renewing their motor vehicle registration. In total, the revenue generated by the sale of the Recreation Passport was $18,816,500.

Those who paid extra for access to Michigan's state parks have a tiny "P" printed on their license plate renewal sticker (the rectangular sticker on the upper-right part of the Michigan license plate).

Michigan DNR spokesperson Mary Dettloff says park rangers have gotten really good at spotting that tiny "P" from a distance.

For 2011, that little "P" signifies $6 million in extra revenue for the park system.

When lawmakers set up the new program, they anticipated the extra revenue. The $6 million will be be broken up according to a formula in the law:

  • State Parks - Capital Outlay (50 percent): $3,043,250
  • State Parks - Maintenance (30 percent): $1,825,950
  • Local Park Grants (10 percent): $608,650
  • State Forest Recreation (7 percent): $426,055
  • Cultural/Historical Facilities in State Parks (2.75 percent): $167,379
  • Marketing (0.25 percent): $15,216

The MDNR recently announced the recipients for local park grants. The local grants range from a minimum of $7,500 to a maximum of $30,000. MDNR officials say if revenues increase with the new "Recreation Passport" program, the maximum grant amount will increase as well.

24.7 percent participated in the program this year. Next year's goal is 30 percent.

Michigan’s only oil refinery is in the middle of a $2 billion dollar expansion project. Marathon Petroleum is expanding its refinery in southwest Detroit to process more heavy crude oil from Canada.

That expansion project is moving the footprint of Marathon’s refinery closer to people’s homes, especially the Oakwood Heights neighborhood in Southwest Detroit. A couple weeks ago, the company made a big announcement. Marathon is offering to buy about 350 homes in Oakwood Heights. The company is offering a minimum of $40,000 dollars plus half of what the home appraises for. There’s also money to help people relocate.

“We think it’s a very generous program. We think the neighborhood is going to be very happy with it.”

Tracy Case is with Marathon. He says the company is planning to demolish the homes it buys and create about a hundred acres of green space next to its refinery.

“You know, I think if you asked anybody in industry, or if you asked anybody that lives next to industry, they’d say yeah, that’s a good thing to have, to have the green space.”

He says the program is voluntary and no one will be forced to move.

There’s a new estimate of the amount of oil that’s been sucked out of the  Kalamazoo River.  And it’s higher than the amount of oil Enbridge Energy claims leaked from its pipeline 16 months ago.  

Enbridge Energy claims a little more than 843 thousand gallons of crude oil leaked from its pipeline near Marshall in July, 2010. But the Environmental Protection Agency says it has recovered more than 1.1 million gallons of oil from the Kalamazoo River during the 16 month cleanup. The EPA says it’s still investigating how much oil leaked from Enbridge’s pipeline.

A little more than 50 years ago, Delores Leonard and her husband moved into their red brick ranch in Detroit.

“I selected it because the sun comes up over there in the morning and I was thinking about my flowers.”

They’ve raised their two kids here and now they have four grandchildren and five great-grandkids and they all live nearby.

But she says on any given day... she doesn’t know what she’ll smell when she steps outside.

“Sometimes it’s a kerosene odor. Sometimes it’s a horrible stench, like at a slaughterhouse. Sometimes, you’re out in public and people will say, ‘where do you live?’ And they’ll say,’ oh yes, I know that area, that stench, I don’t see how those people live there.’”

“There” is zip code 48217. It’s a corner of Southwest Detroit packed with heavy industry.

There’s the state’s only oil refinery, owned by Marathon Petroleum. The salt mine. The city’s wastewater treatment plant. DTE’s coal-burning power plant. Severstal Steel. And many more.

Delores Leonard grew up just a few streets over, in River Rouge. She remembers asking her dad why people were covering their cars with tarps.

“And he said it was because of the fallout, the pollution. Well, if they’re covering their cars so the paint pigmentation won’t peel, then what happens to the person who lives and who’s breathing all this stuff?”

Like Delores Leonard, a lot of people have lived here their whole lives.

The U.S. has worked to get lead out of gas and out of paint, but the biggest source of lead in a consumer product is still on roadways. It’s in the form of wheel weights, used to balance the tires on our cars. The Environmental Protection Agency says about 1.6 million pounds of lead fall off of vehicles each year, and it winds up in the environment. A handful of states is leading the effort to ban lead wheel weights.

If you notice a wobble or vibration when you’re driving, it could mean you’ve lost a wheel weight. Jeff Gearhart is a researcher with the Ecology Center in Ann Arbor. He says wheel weights are about the size of your pinky finger, and there are usually one or two of them for each tire.

“If you look at the rubber part of the wheel, then there’s a metal part, and if you look carefully, then you’ll see a clip-on weight.”

Gearhart isn’t a traditional car guy. He cares about wheel weights because in most states, they’re made with lead. Gearhart says it’s easy to bump a curb, and lose a wheel weight. The EPA says 13% of them fall off. On the roads, the weights get crushed into dust. He says the lead winds up in the soil, in drinking water and ground water.

“Lead’s a neurotoxin, leads to learning disabilities, lower IQ. We don’t know of any safe level of lead exposure in the environment.”

Republican candidates to debate in Michigan this Wednesday

Michigan Radio's Sarah Hulett reports the nationally televised Republican presidential debate will be held at Oakland University this Wednesday. The debate will begin at 8 p.m. and coverage on CNBC will start at 7 p.m. The economy is expected to be a major focus of the debate.

The University has a series of events planned around the debate.

UM nurses approves 3-year contract

Nurses working at the University of Michigan Health System have been working without a contract since July 1. Now they've agreed to a three year deal with UMHS.

From the Detroit News:

The University of Michigan Professional Nurse Council's membership this past weekend approved a new contract that includes a phasing in of health insurance premium increases and includes 3 percent wage increases the first and second years and 4 percent the third year of the contract, plus step increases, said Katie Oppenheim , president of the nurse council.

New Visitor Center for the Detroit River International Wildlife Refuge

U.S. Representative John Dingell's dream of an international wildlife refuge along the Detroit River flyway became a reality in 2001. And the Refuge continues to receive investments.

The Associated Press reports the Detroit River International Wildlife Refuge is getting almost $1.4 million for work next year at the site of a future visitor's center. Officials plan to announce the funding in Trenton today. They are also marking the completion of $1.2 million in cleanup and restoration at the Refuge Gateway.

Earlier this week, there was a landslide at a coal-burning power plant in Wisconsin. We Energies operates the plant. On their property, there’s a ravine next to a bluff on the shore of Lake Michigan. That ravine is filled with coal ash.

Coal ash is what’s left over when coal is burned to create electricity and it can contain toxic substances like arsenic, mercury and lead.

When the bluff collapsed on Monday, mud, soil, and coal ash spilled into Lake Michigan.

Barry McNulty is with We Energies.

“The vast majority of the debris including the soils and even coal ash, remain on land today. But a portion of that debris certainly spilled into Lake Michigan, which includes three vehicles, we believe, some coal ash, different soil from the bluff,” McNulty said.

McNulty said they don’t know how much coal ash got into the lake, but he said they are installing booms and using skimmers to clean up the spill.

The cause of the spill is under investigation.

Colder weather means squirrels are looking for indoor homes and places to cache their food. Some are more aggressive in establishing their indoor domiciles than others.

From the Associated Press:

Officials at Consumers Energy are blaming a squirrel for knocking out electrical service to about 10,000 customers yesterday in the Grand Rapids area. The critter managed to get into a piece of equipment at a substation, briefly knocking out power.

Draft Michigan Rail Plan / MDOT

This was an interesting graph I came across in MDOT's draft report, Michigan State Rail Plan.

The miles of railroad we have in the state today, match what we had back in 1880.

The state went from a peak of 9,059 miles in 1909, to 3,900 miles today - a decline of almost 60%.

It makes sense.

The internal combustion engine began competing with rail at the turn of the last century. Trucks and cars began moving more freight and people.

US Supreme Court

Five Great Lakes states are waiting to find out if the U.S. Supreme Court will hear their case calling for more decisive measures to keep Asian carp from reaching the Great Lakes.

Michigan, Wisconsin, Ohio, Minnesota, and Pennsylvania filed the request this week.

The states want the U.S. Army Corps of Engineers to quickly wrap up its study of how to keep Asian carp from escaping the Mississippi River system through Chicago-area shipping canals. The corps is one of the main agencies responsible for the locks.

John Sellek is the spokesman for Michigan Attorney General Bill Schuette.

“What we really want is to have the Army Corps of Engineers speed up their study,” said Sellek.

“They are taking up to five years or longer to look at this and every minute that goes by could be another fish that’s getting through those canals in Chicago, so what we’re requesting is they speed that up to 18 months at the longest.”

The Great Lakes states also want the high court to order the corps to string nets across smaller waterways that could be escape points for the carp.

At the same time, Michigan and 17 states along the Great Lakes or the Mississippi want a total physical separation of the water systems.

Last night, some people in Michigan and in states as far south as Arkansas looked up and saw a spectacular aurora borealis display.

Here's a time lapse look at the lights that were visible last night near Martin, Michigan:

The tragedy that unfolded for the exotic animals near Zanesville, Ohio on Tuesday night and Wednesday highlighted the lack of regulation in Ohio for a particular type of animal compound.

Terry Thompson kept bears, tigers, lions, monkeys, and other animals on his property.

He reportedly did not display them to the public for compensation, and was not required to carry a permit from the USDA. And an Ohio state law regulating exotic animals had expired.

It looks like a system that monitors drinking water for at least three million people in southeast Michigan will stay online for another year.

The monitoring system gives early alerts if chemical spills are detected—so it keeps contaminants out of the drinking water system.

The system was in danger of shutting down when federal and state dollars ran out. But officials from Macomb and St. Clair counties have each come up with enough money to keep the system going for another year.

But policymakers are still searching for a long-term solution.

Macomb County Commission Chair Kathy Vosburg says a long-term fix will likely mean a small consumer fee.

“Consumers are very willing to pay for that, it comes out to be something like 50 cents to a dollar per household per year.”

But implementing that would take cooperation from the many different cities that send out water bills--and the city of Detroit, which owns and operates the whole drinking water system.

Michigan beekeepers are continuing to lose huge numbers of bees. They join beekeepers from around the country – and the world – who have been dealing with what’s called Colony Collapse Disorder. It’s been around for five years now. Julie Grant visited with some beekeepers, and reports that scientists and the government don’t agree on what should be done to help them.  Here's her story:

Ted Elk is checking out some of his hives. They’re on the backside of a corn field, tucked away in the brush. The colorful boxes are stacked on top of each other.

Some hives are buzzing with activity. He pulls out a comb and scrapes the side:

“And that is all goldenrod honey. See how yellow that is?”

I want to eat it. It’s almost irresistible. But not all the hives look this good.

“Here’s one that’s not gonna make it through winter. It’s light, there’s no bees, there’s no weight to it.”

There’s honey on the comb. But almost no bees.

Elk suspects this hive has colony collapse disorder. There aren’t dead bees around. They’re just gone.

Elk has seen this before. Last winter, he lost 250 hives – and thousands of dollars. When Elk first started keeping bees, he might lose five or six percent in the winter. But nationwide, a 30 percent winter bee loss is average nowadays.

Researchers still aren’t sure exactly what’s causing Colony Collapse Disorder. But they do know there’s a lot of stress on bees. Beekeepers take their hives all over the country – to Florida to pollinate oranges, to California for almonds, to New York for apples, and elsewhere. The beekeepers take the bees honey, and often feed them cheap high fructose corn syrup, or nothing at all. Plus, they can have mites and bacteria. And there are 28 viruses that can affect bees.

The U.S. Green Building Council’s annual conference was held in Toronto this week.  “Greenbuild 2011” was four days of seminars, classes, and discussions about how to construct buildings and homes, using more environmentally friendly methods.

Asian carp have been making their way up the Mississippi and Illinois Rivers toward the Great Lakes for decades. Bighead and silver carp are the species people are the most concerned about.

Government officials are trying to keep the carp out of Lake Michigan. One of the main methods they’re using is electrical shock. There’s a man-made canal near Chicago that connects the Mississippi River system with Lake Michigan. And on that canal is a system of three underwater electric barriers built by the Army Corps of Engineers.

I recently had a chance to visit the electric barriers. You can’t see the actual barriers, because the electrodes are underwater. But the Army Corps invited me into the control room of Barrier 2B. It looks about like you’d guess – lots of computers and gauges. There are a couple large mounted Asian carp on the shelves.

Chuck Shea is a project manager with the Army Corps.

He says the barriers repel fish by emitting very rapid electric pulses into the water... which, if you’re a fish, is not a whole lot of fun.

“The idea is, as a fish swims in, the further it goes it’s getting a bigger and bigger shock and it realizes going forward is bad, it’s uncomfortable, and it turns around and goes out of its own free will and heads back downstream.”

The electric bill for this barrier runs between $40,000 and $60,000 a month.

Dow Chemical

Dow Chemical first unveiled its solar shingle two years ago, with plans for a limited release in mid-2010.

Now the company announced that the shingles will be available to some customers starting this month. The company says they're starting in the strongest markets for solar this month. The shingles will first be available in Colorado, and a "rolling launch" will occur in markets from California to the "East Coast."

In a press release, Dow said the shingle "protects the home like a standard roofing shingle while providing energy that saves the homeowner money":

Dow can now serve the need of homeowners who want to go solar, but aren’t willing to accept the complexity and sub-optimal aesthetics currently offered by bulky, rack-mounted systems.

Booth Mid-Michigan reports that Dow Chemical CEO Andrew Liveris called Dow's solar shingle "a game changer that will address an estimated $5 billion market by 2015."

From Booth Mid-Michigan:

Dow hasn't reported a price for the shingles, but said the cost to homeowners will be set by the channel to market, and will depend on the size and configuration of the home and desired power generation. Dow officials said the cost of solar shingles can be thousands of dollars less than solar panels installed on top of a roof.

TRAVERSE CITY, Mich. (AP) - A company is applying for state permits to construct a copper and silver mine in Michigan's far western Upper Peninsula.

Orvana Minerals Co., a subsidiary of a Canadian company, is proposing to build a mine near Lake Superior in Gogebic County. Orvana is targeting 798 million pounds of copper and 3.5 million
ounces of silver.

Company president Bill Williams says the mine would operate about 14 years and have about 250 people on the payroll.

Orvana will need 13 permits from the Michigan Department of Environmental Quality, including one to build and operate the mine. The others would deal with issues such as air quality, wastewater discharges and wetlands development.

DEQ officials say the mine will have to meet strict environmental standards to qualify for the permits.
