A Lansing zoo confirms its critically endangered black rhino is pregnant. Potter Park Zoo officials say it took almost a year to get the female rhino pregnant.

The rhino's name is Doppsee. While it is too early to see a fetus, lab test show she is expecting.

According to the International Union for Conservation of Nature and Natural Resources (IUCN) there are only 5,000 black rhinos remaining in the wild and only about 60 at zoos in the United States.

The Michigan Department of Natural Resources is starting spring work on maintaining the state’s fish population.

The DNR says it expects to collect about 30 million eggs from walleye in the Muskegon River in the coming weeks. The state also collects eggs from steelhead on the Little Manistee River.

State environmental regulators are nearing a long-awaited decision on a permit to expand a hazardous waste facility in Detroit.

U.S. Ecology first applied for a permit to expand storage capacity ten-fold at its Detroit North facility in 2015. But the application stalled in the face of major political and community opposition.

The company that owns and operates Detroit’s massive trash incinerator abruptly announced Wednesday that it’s closing down the facility.

The controversial incinerator is near the I-75/I-94 interchange on the city’s near east side, adjacent to the Midtown area. It’s been operating for three decades, though never without controversy.

A new report commissioned by the Environmental Law and Policy Center urges Great Lakes states to mitigate and prepare for the "profound" effects of climate change.

The report, authored by more than a dozen Midwest and Canadian researchers, says Great Lakes states will see more very hot days, increases in heavy rainfall and flooding, declines in crop yields, and threats to drinking water.  

A new set of rules takes effect this week for boaters and fisherman in Michigan.

Beginning Thursday, watercraft users will be required to take steps to prevent the spread of aquatic invasive species.

Several hundred Ann Arbor high school and university students walked out of class Friday to urge swifter action on climate change.

University of Michigan student Logan Vear is an organizer. 

She points to a new report from the UN Intergovernmental Panel on Climate Change that warns that humans must completely eliminate their carbon dioxide emissions by 2050. That would give the world a fighting chance of limiting global warming.

But many companies - including Michigan's two largest utilities - only promise to reduce their CO2 emissions by 80% by then.

"And I think there are a lot of existing deadlines like that, not only in Michigan but across the nation, that obviously are not good enough," says Vear.

Federal lawmakers, two from Michigan and two from Illinois, have introduced bills that would require the federal government to address concerns about petroleum coke exposure.

Petroleum coke is a byproduct of refining crude oil. 

The legislation calls for federal agencies to complete a study of the health and environmental risks posed by petroleum coke. It also would require the implementation of federal safety regulations for the storage and transportation of petroleum coke. The standards would be based on the study's findings.

The Michigan-based water law non-profit “For Love of Water,” or "FLOW," filed an amicus brief this week in support of a lawsuit against the Wisconsin Department of Natural Resources.

Last April, the WDNR approved the City of Racine's request to withdraw an annual average of 7 million gallons of Lake Michigan water per day and send it to their customers in another community, Mount Pleasant.

A new report raises questions about the citizen science projects that emerged during the Flint Water Crisis. 

But critics charge the report’s authors have ulterior motives.

In late February, four Canadian wolves were captured and then released onto Isle Royale National Park in a continued effort to grow the current wolf population and restore predation, a "key ecosystem dynamic," according to a press release from the National Park Service. 

U.S. Senator Gary Peters is calling for a review of the Environmental Protection Agency's PFAS Action Plan.

Senator Peters and a group of colleagues sent letters to a number of agencies this week, including the EPA and the Department of Health and Human Services.

A new report says the groundwater at some of Michigan's coal ash storage sites is contaminated with toxic chemicals, especially arsenic.

The report compiled data that's required by a new federal rule, which mandates testing, disclosure, and cleanups if necessary.

The report notes Consumers Energy disclosed arsenic levels 48 times the federal safety standard at the D.E. Karn Power Plant, and DTE Energy disclosed arsenic levels 38 times the federal safety standard at its Trenton Power Plant.

Charlotte Jameson of the Michigan Environmental Council calls those levels "alarming.

An Ohio farm in the Lake Erie watershed is suing to stop people from using the Lake Erie Bill of Rights, fewer than 12 hours after Toledo voters approved it.  

The Lake Erie Bill of Rights amends Toledo's charter to try to give residents a legal basis to intervene in the lake's interests. 

The big concern for many is phosphorus-containing fertilizers from farms. The phosphorus encourages toxic cyanobacterial blooms.  

More than 200 hunting, fishing, conservation, and outdoor recreation industry groups have submitted public comments in favor of the U.S. Army Corps of Engineers' plan to keep Asian carp out of the Great Lakes by constructing new technologies at the Brandon Road Lock and Dam outside Chicago.

The Michigan Department of Environmental Quality has released results of a 2018 state-wide sampling of public, school and tribal water supplies for per-and polyfluoroalkyl substances, or PFAS.

Of 1,114 public water systems, 119 have been found to contain some level of PFAS. No tribal water supplies contained PFAS.

Indigenous water walkers will travel from Mackinaw City to Lansing to call for a shutdown of Enbridge’s Line 5 oil pipelines.

Sarah Jo Shomin, Nancy Gallardo, and Cody Bigjohn Jr. plan to walk 311 miles over the next 17 days.

They're calling the journey "N'biish Nibimosaadaanaa", which is Anishinaabemowin for "We Walk for Water."

Updated 3/14/19: As a "bomb cyclone" prepares to hit parts of the upper Midwest, we're re-sharing this explainer about what a bomb cyclone is exactly.

Original Post: Parts of Michigan could experience winds up to 50 miles per hour this weekend, thanks to a weather phenomenon called explosive cyclogenesis. You might have heard it called a bomb cyclone or bombogenesis in other media and weather reports.

PFAS discharges from Kalamazoo's wastewater treatment plant are now under the state limit of 12 parts per trillion for surface water.

That's down from a high of about 53 parts per trillion last summer.

State and local officials are conducting new tests to check the spread of the 1,4-dioxane plume in groundwater in Ann Arbor's West Park area.

Dan Hamel is with the Department of Environmental Quality. He says a current consent agreement between the DEQ and the company requires Gelman Sciences to prevent the spread of the suspected carcinogen.

A number of environmental groups, Democratic politicians, and citizens who live in areas contaminated with PFAS are criticizing Thursday's PFAS Action Plan announcement by the U.S. EPA.

PFAS is a class of chemicals linked to health problems that's contaminating many drinking water systems.  

Under strong pressure from Congress, the Environmental Protection Agency said Thursday that it will move ahead this year with a process that could lead to setting a safety threshold for a group of highly toxic chemicals in drinking water.

Acting EPA Administrator Andrew Wheeler said the immediate focus would be on two of the most common chemicals in the group, both of which have been phased out by manufacturers but remain in the environment and have suspected links to health threats ranging from cancer to decreased fertility.
