Michigan homeowners improve on energy efficiency

by Tanya Ott for The Environment Report

It’s cold outside… and maybe inside, if your house isn’t properly insulated. Home energy efficiency is a big issue and a new study gives Michigan kudos for making it a priority.

Randy Rice has lived in his Southgate, Michigan house for 13 years. He’s lived there – and often shivers there…

“Certainly believe that the air was leaking upstairs. We could feel some breezes. I just saw dollars flying out the window.”

Rice replaced the windows five years ago and it helped… but he still worries about leaks around the windows. So he called in...

“Amanda Godward, with Ecotelligent Homes. I’m the owner and energy auditor.”

Godward’s first step is to interview customers like Randy Rice. She takes house measurements, checks out insulations in the attic and windows. Then…. she goes all high tech with the “thermal infrared scan.”

“We use this to find flaws in the insulation, in the walls, without having to do any destructive testing.”

She turns on a fan that pulls all of the air out of the room. It creates a vacuum so cold air from the outside is pulled inside. She can see, on a scanner, all the little cracks and holes where air is sneaking in.

Snowy owls travel southward in search of food, several Michigan sightings

The Snowy Owl is traveling south in search of food. There have been multiple sightings in Michigan.

Snowy owls typically live in the northern reaches of the arctic tundra.

Living year round in the arctic shows how tough these birds are.

But this year they've been traveling south in search of food.

The owls have been spotted in states such as Massachusetts, Kansas, Illinois, Michigan, and Minnesota, according to the U.S. Fish and Wildlife Service.

To see where they've been spotted in Michigan, click on the slides above for a Google Map.

So why are they flying down here?

Biologists think the growth in Snowy owl sightings around the U.S. is due to a drop in the owl's main prey in the Arctic - lemmings. Lemmings go through boom and bust periods, and right now, lemming numbers are probably down, so the owls are scrounging around here for rodents, rabbits, fish, or any other suitable food source.

Similar cycles occur with other birds of prey.

The Great Gray owl, which normally keeps to northern Canada forests, has been known to fly south when its food is in short supply.

Reporter David Sommerstein produced a story on Great Gray sightings in a piece he did for the Environment Report back in 2005.

It was a year the owls were flying south and was one of the biggest Great Gray owl migrations on record.

Take a listen to a "Rare Visit from a Northern Neighbor" - the audio file below.

I love hearing ornithologist Gerry Smith's reaction when he spots the "first Great Gray owl that's made it across the border."

"I'll be a son-of-a-gun. That is so... bler... I am now VERY enthusiastic! Hey! .... I'm going to get my scope..."

And while you're out, keep your eye's peeled for rare visit from another northern neighbor - the Snowy owl.

Here's one spotted in 2005 in Wisconsin:

We all should be so lucky.

More daylight starting tomorrow, happy solstice!

Today is the winter solstice, the shortest day of the year.

The BBC reports that "more than 1,000 people" gathered at Stonehenge in Wiltshire County, England to mark the occasion.

And Arch druid Rollo Maughfling remarked  "the solstice celebration had been 'a very jolly occasion.'"

So in Ann Arbor, the sunset tonight is at 5:05 p.m... tomorrow night it will come at 5:06 p.m.

But weirdly, the winter solstice does not coincide with earliest sunset times.

Justin Grieser explains why in the Washington Post. Grieser says it has to do with the sun's declination and the shifting time of solar noon:

In late November, the effect of a later-shifting solar noon begins to counteract the effect that the sun’s lowering declination has on pushing sunset earlier. Eventually, sunset reaches a minimum during the first week of December. While we would expect the earliest sunset to occur closer to the winter solstice, the rapid forward shift in solar noon causes sunset to creep later more than a week before then.

Christmas tree debate: real or fake?

Lauren and her potted tree. It will stay outdoors until Christmas Eve, when it will be brought in for 14 hours.
Photo by Jennifer Guerra

There’s a long-running debate about which kind of Christmas tree is greener: real or artificial.  We wanted to try to settle that debate... or at least add to the discussion:

Lauren Northrop and her husband Tom are big fans of Christmas.

“We love celebrating it, I love decorating, but we always have this dilemma: what do we do about a tree?”

They didn’t want a plastic tree because it’s, well, plastic. And they didn’t like the idea of bringing a live tree into their house, only to have it die and then drag it out to the curb to be recycled.

So they skipped the Christmas tree thing altogether for the last four years. But then, their son was born.

They bought a live, baby Christmas tree with its roots still intact. That way, when Christmas is done and the ground thaws, they can plant it in their backyard.

“I was planning to keep the tree inside until December 25th so that we could decorate it and put lights on it. When we went to buy it they said if you do that, it probably won’t survive.”

That’s probably way too much hassle for most people.

Great Lakes restoration funding survives budget cuts

People who are working on cleaning up the Great Lakes got some good news this week. After months of negotiations, the 2012 federal budget contains $300 million for the Great Lakes Restoration Initiative.

That money will be used to clean up pollution, deal with invasive species and restore wildlife habitat. A lot of these projects are already underway.

Jeff Skelding is the campaign director for the Healing Our Waters-Great Lakes Coalition. He says in a time when many budgets are getting slashed, funding for Great Lakes cleanup will remain steady.

“We have pretty much full support from both Republicans and Democrats in the Great Lakes Congressional delegation. I mean, they see the wisdom of infusing federal funding into the region, not only to clean up the Lakes which of course is very important, but the ancillary benefit we get from that is the economic benefits of investing these funds.”

The budget also includes more than $500 million to help Great Lakes states upgrade their aging sewer systems. When it rains, the sewers often get overloaded, and raw sewage can wash up on beaches.

Great Lakes wolves to be taken off endangered species list

Canis lupus.
USFWS Midwest

Update 4:19 p.m.

The U.S. Interior Department announced today gray wolf populations in the Great Lakes region have recovered and no longer require the protection of the Endangered Species Act.

They will lose their federal protection as of January 27, 2012.

From a U.S. Fish and Wildlife Service press release:

"Gray wolves are thriving in the Great Lakes region, and their successful recovery is a testament to the hard work of the Service and our state and local partners," said Fish and Wildlife Service Director Dan Ashe. "We are confident state and tribal wildlife managers in Michigan, Minnesota and Wisconsin will effectively manage healthy wolf populations now that federal protection is no longer needed."

The Associated Press reports that Michigan Department of Natural Resources Director Rodney Stokes says "the change will give state officials more flexibility to deal with problem wolves and make people more supportive of having the predators in their midst."

Wisconsin officials will issue permits allowing landowners to control "problem wolves" on their property.

11:25 a.m.

The wolf population in Michigan has been growing. Michigan DNR estimates put it at more than 650 animals for 2010-2011. The number was around 430 wolves in 2004-2005.

Wolves in the western Great Lakes region have been taken off the Endangered Species List before, and conservation groups have successfully sued the federal government to put them back on the list.

Now, the Associated Press reports western Great Lakes wolves will be delisted again.

From the AP:

The Obama administration is taking gray wolves in the western Great Lakes region off the federal endangered species list.

The Associated Press obtained a Wednesday statement in which Interior Secretary Ken Salazar says the more than 4,000 wolves in Michigan, Minnesota and Wisconsin have exceeded recovery goals and
no longer need federal protection.

Responsibility for managing and protecting those wolves will be turned over to state wildlife agencies. The populations will be monitored for at least five years to make sure they remain at sustainable levels.

The Interior Department also says it's reconsidering a previously announced plan to remove endangered species protections for wolves in 29 Eastern states, even though they aren't believed
to have any established wolf populations. Officials say they'll decide on the status of Eastern wolves later.

State officials say they're prepared for federal delisting. The state of Michigan has a wolf management plan.

Once management is turned over to the state, people would have more flexibility in killing "problem wolves." From Bob Allen's report on The Environment Report:

The plan would give people the authority to defend against attacks on their pets and livestock, and it would allow them to cull wolves in places where they’re putting a lot of pressure on deer.

The current state management plan does not call for a hunting season on wolves. It would take an act of the state legislature to make a hunt a reality.

$300 million for Great Lakes cleanup, and a '12 Days of Invasive Species Christmas'

A map of 664 Great Lakes Restoration Initiative projects listed on the GLRI website.
greatlakesrestoration.us

One item that has escaped the budget tie-ups in Congress is funding for Great Lakes cleanup.

Congress approved $300 million in funding for the Great Lakes Restoration Initiative for fiscal year 2012.

From the Associated Press:

The money was included in a larger spending bill that cleared the House and Senate last week and is awaiting President Barack Obama's signature...

Jeff Skelding of the Healing Our Waters-Great Lakes Coalition says next year's federal budget is a victory for people who depend on the Great Lakes for drinking water and jobs.

The approved funding keeps the ball rolling for the historic levels of federal investment in Great Lakes cleanup through the Great Lakes Restoration Initiative.

The Initiative was kicked off in 2010 with $475 million in restoration funds aimed at cleaning up toxic hot spots, curbing runoff pollution, fighting invasive species, and restoring habitat.

2011 saw a decrease in funding from Congress to just under $300 million.

Jeff Skelding, the campaign director of the Healing Our Waters-Great Lakes Coalition, told Rebecca Williams of the Environment Report earlier this year that debate about funding for Great Lakes cleanup cuts across party lines:

"...one thing about the Great Lakes Restoration Initiative is because of the nature of the program, federal funding to clean up the Great Lakes, and to help the economy, it's really a bi-partisan issue. We have really received great support from both Republicans and Democrats in the Great Lakes Congressional delegation. So that gives us hope as we stare down the significant cuts that are happening across the federal budget."

The AP reports the Great Lakes region is also "expected to get $533 million in loans for sewer upgrades."

Fingerprinting mercury pollution

Photo by Laura White

Mercury is a neurotoxin. The Environmental Protection Agency says mercury can be especially harmful for babies and kids. Mercury can affect their developing brains and harm their memory, attention, language and motor skills.

Mercury is naturally-occurring. Volcanoes emit mercury and so do hot springs, like the ones in Yellowstone National Park.

But the EPA points out... the largest manmade source of mercury emissions in the U.S. comes from coal-burning power plants.

Joel Blum is a professor of Earth and Environmental Sciences at the University of Michigan. Blum says when power plants burn coal, mercury is emitted as a gas.

“In order to become toxic, it has to be transformed into a particular form known as methylmercury which is something that happens in the environment.”

So... mercury falls from the atmosphere, and is converted to methylmercury in the water. That toxic form builds up in fish... and it can build up in us when we eat fish.

But for years... there’s been a big debate about where that mercury goes when it’s released from a power plant smokestack.

“How much is deposited nearby, close to the plant, and how much goes into what we call global pool of mercury - basically goes into the atmosphere and stays there for a long period of time and mixes with mercury from other sources.”

Joel Blum and his colleagues have started to crack that puzzle with some careful detective work. They were able to track mercury emissions from a power plant in Florida... and they found that a high proportion of the mercury ended up nearby.

They did this by looking at chemical fingerprints.

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.

Flame retardant chemicals show up in air around Great Lakes region

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.

You can learn more from The Environment Report's five part series on flame retardants.

Kennecott mine opponents to appeal judge's go-ahead ruling

Drilling began at the Eagle Mine this past September. This aerial photo was taken in September of 2011.
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.

Signs of a bigger deer harvest in 2011

Deer populations appear to be increasing slowly in the UP and the northern lower peninsula, according to Michigan DNR officials.
USDA.gov

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.

New DNR advisory council weighted toward timber interests

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 moving south

A hungry black bear left its paw print in a frame of Terry Klein's beehive.
Photo by Terry Klein

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.

What's the use? State cuts back on salmon stocking in Lake Huron

Juvenile Chinook salmon. Populations of the popular sport fish have collapse in Lake Huron.
USFWS

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.

Less money for cities to fix water systems?

Water at the Senior Citizens' Housing Center in Louisville, NY before it is filtered.
Julie Grant/The Environment Report

by Julie Grant for The Environment Report

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.

Mining in the UP, what does the state get in return?

Drilling began at the Eagle Mine this past September. This aerial photo was taken in September of 2011. The mine is 25 miles northwest of Marquette, Michigan.
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?
