A bird once common to Michigan nearly became extinct. Three agencies say they'll work together to make sure work to save the bird continues. The following information comes from the U.S. Fish and Wildlife Service:

"The U.S. Forest Service, U.S. Fish and Wildlife Service and Michigan Department of Natural Resources have signed a memorandum of agreement pledging to continue conservation efforts for the endangered Kirtland’s warbler, regardless of the warbler’s status under the Endangered Species Act.  

The MOU is a first step toward eventually removing the Kirtland’s warbler from the list of endangered and threatened species.

Many people call Detroit a “post-industrial” city.

But residents in one corner of the city still live alongside a cluster of heavy industry, and they say it’s affecting their health. Now, community members in southwest Detroit want the state to do more to find out just how extensive those health impacts might be.

Southwest Detroit is home to a number of heavy industrial sites. Some effects can be seen with the naked eye: from hazy diesel truck fumes to an eerie metallic dust residents say has rained down on their neighborhood. But others are more subtle. The neighborhood is full of children with asthma. Residents also blame the pollution for cancer and other deadly illnesses, though such a link hasn’t been definitively established.

Now, southwest Detroit residents are pushing hard for the government to launch a thorough investigation into those potential health impacts.

The U.S. Environmental Protection Agency says gas stations can now sell gasoline blended with 15% ethanol for all cars built in 2001 or after. Right now, when you fill up in Michigan, your gasoline has 10% ethanol.

The EPA says E15 gasoline will help reduce our need for foreign oil. Ethanol is made from plants like corn. The EPA only tested the effects of E15 on emissions and catalytic converters.

But ethanol is corrosive. Patrick Kelly is with the American Petroleum Institute.

He says E15 might do some harmful things, like corrode rubber parts, or make your check engine light go on for no reason. And it could end up in the wrong gas tanks, even though the EPA will require labeling.

It's been five years since the deep injection wells in Romulus, Michigan stopped pumping hazardous waste close to a mile underground.

Now those wells might reopen. From the Detroit News:

The two wells located off Citrin Drive have drawn opposition in the Romulus area long before original owner Environmental Disposal Systems (EDS) began accepting waste there in 2005. Operations were halted when the company ran into financial problems and state inspectors discovered leaks in the above ground apparatus. There was no lasting environmental damage, but the findings fueled opposition from local residents...

This week, EPA officials appear ready to grant tentative approval for Environmental Geo-Technologies' underground injection control permit, which would bring the reopening of the site one step closer to reality.

The deep injection wells in Romulus have been a controversial subject for decades.
