One of the nation's largest electric utilities says it will reach net zero carbon emissions by the year 2040. 

It's the most ambitious goal yet for a U.S. electricity company. Five electric utilities, including DTE Energy, have committed to reaching net zero by 2050.

Net zero carbon emissions means a combination of eliminating and offsetting carbon dioxide emissions to achieve zero carbon emissions attributable to the company.

Michigan residents are sending more trash to the state’s landfills than they have since before the Great Recession.

Last year Michigan homes and businesses sent more than 43 million cubic yards of trash to the landfills.

Minnesota-based 3M will pay $55 million to Wolverine Worldwide to address PFAS contamination in Kent County.

Wolverine Worldwide is based in Rockford. It has said it could spend $113 million to meet its obligations in a settlement with the State of Michigan and two townships over PFAS. That money includes $69.5 million to extend a municipal water system to more than 1,000 residences where PFAS has been found in well water.

The U.S. Environmental Protection Agency indicates it will take years to regulate PFAS in drinking water, if it does at all. 

The USEPA has proposed to regulate two forms of the thousands of chemicals in the per- and polyfluoroalkyl substances family. PFOA and PFOS were the most commonly used.

A proposed large solar farm is moving ahead for approval. The 24 megawatt solar installation could power the equivalent of five thousand households. 

“When you add in the hydro energy that we generate, as well as the methane that we capture from the landfill, this gets the city of an obvious municipal operations government footprint — our electrical use — to about zero. Hundred percent powered with clean, renewable energy,” said Missy Stults, Sustainability and Innovations Manager for the City of Ann Arbor.

The Board of Regents of the University of Michigan announced at a meeting on Thursday that it will put a freeze on new fossil fuel investments. This means that it will not make new investments in the fossil fuel industry while it studies its own investment policy.

The announcement came from Regent Mark Bernstein, right after U-M Central Student Government President Ben Gerstein discussed a Big Ten resolution, where student governments from Big Ten universities called on their institutions to freeze fossil fuel investments.

There may be hope for bat populations devastated by a disease caused by a fungus. 

While waves and record high water levels pound away at shoreline properties, state lawmakers are trying to pound away on new laws to protect property.

One bill debated Tuesday in the House would allow property owners to build temporary shoreline barriers to protect against erosion, even without a permit.

Michigan and ten other states are urging the U.S. EPA to set stricter limits on emissions of a known carcinogen called ethylene oxide, or EtO.  The chemical is used to sterilize medical equipment.   In a letter to the EPA, state attorneys general say the agency is six years behind schedule in setting stricter limits on EtO.  The chemical is linked to a higher risk of breast cancer, among other health issues.   

The city of Ann Arbor is considering a carbon tax on internal operations that rely on fossil fuels and carbon emissions. This comes three months after the city declared a climate emergency and set a goal of carbon neutrality for the city by 2030.

President Donald Trump's proposed budget won’t fund a barrier to stop Asian carp from entering the Great Lakes despite recent remarks that he would protect the lakes from the invasive fish.

It does, however, include one win for the Great Lakes: another $123 million in 2021 to build a new lock in Sault Ste. Marie ($75 million was already appropriated to start construction on the lock in 2020).

Flint pediatrician, Dr. Mona Hanna-Attisha, testified during a House hearing on Tuesday for the Environmental Protection Agency's proposed changes to the Lead and Copper Rule.

The proposal has been criticized for not being aggressive enough to effectively decrease lead levels in lead-contaminated drinking water.

North American river otter Nkeke is a new mom following the birth of two pups Sunday, February 9 at Lansing's Potter Park Zoo.

The two pups are the second successful birth for Nkeke and otter dad Miles.

Many residents in northern Kent County say they're happy with a proposed settlement agreement over contamination from chemicals known as PFAS in the area, though some said they wish the agreement would go further. 

The Michigan attorney general's office held a forum to hear public comments on its consent decree Monday night in Rockford. More than 100 people showed up.

Environmentalists, the Michigan Attorney General, and many others are keeping an eye on every step of the process of replacing Line 5 at the Straits of Mackinac. Enbridge’s Line 5 is the pipeline that crosses the Upper and Lower peninsulas of Michigan to transport oil and liquid natural gases to Canada.

But there’s another place where Line 5 is going under a body of water that’s part of the Great Lakes. Enbridge is replacing that pipeline under the St. Clair River just south of Lake Huron.

The Ann Arbor City Council has approved $3.8 million worth of upgrades to improve the city’s water system. $3.4 million of that money will go to UV-treatment upgrades in order to combat a parasite called cryptosporidium.

State Attorney General Dana Nessel announced that paperwork has been filed on a proposed settlement with Wolverine Worldwide over PFAS contamination.

Nessel’s office announced a tentative agreement in December. The state and two townships in northern Kent County had filed lawsuits against the shoe company for contaminating water with chemicals in the PFAS family.

The Michigan Department of Environment, Great Lakes, and Energy is giving two companies in Detroit until this Friday to come up with a new protections for the Detroit River. Two previous plans have been rejected as inadequate.

A dock collapsed along the Detroit River in November. EGLE instructed Revere Dock, LLC and Detroit Bulk Storage to submit an interim plan to keep further aggregate rock and soil from getting into the river.

When Detroit firefighters found pits filled with liquid in the basement of a warehouse owned by Gary Sayers, state officials had to assume the worst.

That's because similar pits in the basement of Electro-Plating Services in Madison Heights were heavily contaminated with hexavalent chromium, a known carcinogen.  

Chromium turns liquids green, which resulted in a "green ooze," spilling from the EPS site onto I-696 in December.

Now, test results show that the liquid in the warehouse pits is in fact contaminated, but primarily with heavy metals. 

If you want to weigh in on the state's proposal to regulate seven different types of PFAS chemicals found in drinking water, you have until midnight on Friday, January, 31.

Preliminary test results indicate pollution from Electro-Plating Services in Madison Heights is not contaminating drinking water, nor is it moving into residential areas.
