 Updated 2:38 p.m. to include statement from Enbridge Energy. 

Michigan Governor Gretchen Whitmer plans to revoke the easement the state granted in 1953 that allows Enbridge Energy’s Line 5 to cross the Straits of Mackinac.

The announcement came as the Department of Natural Resources released a review of Enbridge’s record over the 67 years the Line 5 dual pipelines have sat on the bottom of the Straits between Lake Michigan and Lake Huron. The DNR cited the Canadian pipeline company’s “historic failures and current non-compliance” as reasons to revoke the easement.

Potter Park Zoo announced the recent birth of two critically endangered cotton-top tamarins to parents Yuri and LG. This is the pair’s third litter at the zoo since 2018. Their first pair was born October 2018 and another pair in June 2019.

All eight of the tamarins, including the two babies recently born October 2 are living in a family group at Potter Park Zoo.  

One chemical in the PFAS family is showing up more often and in greater concentrations in fish.

The PFAS chemical is PFOS.

The oil pipeline company Enbridge pushed to limit what a state regulator could consider regarding relocating the Line 5 twin pipelines across the Straits of Mackinac.

Enbridge did not want the Michigan Public Service Commission to consider a proposed tunnel under the Straits of Mackinac which would house a new section of Line 5.

An industry group says some solar panel installers are thinking about leaving Michigan. That’s because they believe sales will drop dramatically because of a cap on how much residential and commercial solar a utility must allow.

A 2016 law sets a cap on some outside renewable energy sources  based on one percent from of a utility’s average peak demand. Consumers Energy is close to hitting that peak.

Research shows chemicals banned years and even decades ago are showing up in some Great Lakes shorebirds. Scientists found P-C-Bs used as a coolant in electrical transformers, fire retardants called P-B-D-Es and derivatives of the insecticide D-D-T in terns. The pollutants were at levels high enough to potentially harm the health of the birds. 

Surface water levels of PFAS chemicals have plummeted in a creek that flows into the Huron River, after a state investigation.  

Investigators went upstream from Ann Arbor to try to discover the source or sources after PFAS chemicals showed up in the city's treated drinking water in 2018. 

A main source was discovered to be the Wixom Wastewater Treatment Plant, which was discharging PFAS-laden effluent from Tribar Manufacturing, a plating company, into Norton Creek, which flows into the Huron River. 

Some environmental groups are criticizing the Michigan Department of Natural Resources for a planned carbon offset program.

The DNR is planning a pilot program that would account for the carbon taken up by the Pigeon River Country State Forest. The forest absorbs carbon dioxide. That has value on a voluntary carbon market. Polluters can buy that carbon value as a way of offsetting their greenhouse gas emissions.

A new report found Michigan’s energy use changed dramatically during the first few months of the pandemic.

In the second quarter electricity use dropped by 32% in the industrial sector compared to the same time period last year. That's the biggest drop in the country.

Michigan residents who are behind on their water bills will soon be getting some relief.

The Michigan Department of Health and Human Services will distribute more than $20 million to 116 water utilities, through an intermediary, to cover water bill debt that their customers accrued since March 1 when the pandemic emergency began.

The operator of a Detroit dock site that partially collapsed into the Detroit River late last year will pay the state $60,000 in fines.

The Revere Dock, which was illegally storing limestone aggregate along the river when the site collapsed in late November, 2019, has also entered into a consent agreement with the Michigan Department of Environment, Great Lakes, and Energy. A sinkhole also formed on the site sometime after the collapse.

A report from the Union of Concerned Scientists says Michigan's electric utilities are losing money at times because they're using their own coal-burning plants when it would be cheaper and cleaner to buy electricity from market sources.

And that cost is being passed on to consumers.

Joe Daniel is an energy analyst with USC. He says statewide, electric customers pay on average an extra $60 a year on their bills because of the issue, which appears to happen simply because of past practice.

Storm chasers and meteorologists observed a record number of waterspouts over the Great Lakes this month, according to the Toronto-based International Centre for Waterspout Research. 

The group confirmed 240 of the spectacular weather events over the Great Lakes between September 28 and October 4. 

A waterspout can form on a cloudy day, when cold air passes over warmer waters. The resulting vortex sucks down condensation from the cloud cover, creating a phenomenon that looks like a tornado.

Deer season started for bow hunters on October 1. The Department of Natural Resources will be testing harvested deer for Chronic Wasting Disease (CWD). Even if a deer looks and acts healthy, it still might be affected by the neurological disorder.

A plume of the toxic chemical 1,4 dioxane released by the former Gelman Sciences complex has contaminated wells and threatens Ann Arbor’s main source for drinking water. A proposed amendment to a consent judgement would require more groundwater testing and more cleanup of groundwater to remove the chemical.

The proposal would also pump the treated water into the nearby First Sister Lake. However, the treated water will still have trace amounts of dioxane in it.

A scientific expert says Canadian pipeline company Enbridge Energy has not submitted enough information to the state for permits to build a tunnel under the Straits of Mackinac. The groups Oil and Water Don’t Mix and the National Wildlife Federation included a geological engineer who build tunnels in an online news conference.

Brian O’Mara reviewed the reports in the tunnel proposal submitted to the Michigan Department of Environment, Great Lakes, and Energy. O’Mara says Enbridge did not take nearly enough core samples of bedrock along the route of the tunnel, and what they did take showed it’s not solid bedrock all the way across.

The Michigan Public Service Commission says it will update state requirements for long range plans submitted by electric utilities.

The agency is asking stakeholders to submit recommendations for how these plans, known as Integrated Resource Plans, or IRPs, should change to help meet the governor's new target of carbon neutrality by the year 2050.

Carbon neutrality means on balance, no new carbon dioxide emissions are added to the atmosphere, through a combination of carbon emissions reductions and carbon offsetting, via things like planting forests and other carbon capture projects.

Farms housing thousands of animals are one of several sources contaminating the Pine River and dividing a mid-Michigan community.

Murray Borrello, wearing khakis and a loose-fitting brown button-up, walked down a backroad during the summer of 2019 listening to the sounds of the woods. Water from the Pine River flowed slowly beneath him as he looked out over a bridge.

“Oh, I hear a frog,” the Alma College geology and environmental studies professor said. “That’s a good sign.” 

Detroit will be spending more than $9 million to deal with lead-based paint in homes. Although lead-paint has been banned since the 1970s, the old paint on walls, floors, and window sills is still toxic and a leading cause of high blood lead levels in children.

The federal grant from Housing and Urban Development had very specific requirements.

The state of Michigan is expanding quarantines to try to stop a pest from killing hemlock trees. Michigan’s 170 million hemlock trees are important because they help prevent erosion along streams and keep them cool, which helps fish habitat. The Michigan Department of Agriculture and Rural Development (MDARD) says hemlocks are also important to the timber and lumber industries, nursery and landscaping industries, the Christmas tree industry and the tourism industry.

The Hemlock Woolly Adelgid is the insect pest killing hemlocks in five counties along Lake Michigan: Allegan, Muskegon, Oceana, Ottawa, and Mason. It feeds on the starches of the trees.

The state of Michigan is launching a pilot effort to establish a wastewater surveillance system for COVID-19.

Yes, the novel coronavirus can be detected in human poop—even when people are asymptomatic, or have yet to show symptoms. And there are a number of pre-existing wastewater testing programs already running in Michigan.

At the shoreline, between lake and land, Melissa Wiatrolik reflects on those who were here before Michigan became Michigan. She had been raised in a community that honored the dead, that understood that their ancestors were always present. As a child, she had watched her own family clean the gravestones of those before her. She had attended ghost suppers to both celebrate and feed the deceased. She had grown up with remembrance, and now, at the shores of Lake Michigan, Wiatrolik worked to keep her ancestors at peace.

Some clinical trials for potential COVID-19 vaccines are going well—but don’t expect a vaccine any time this year, says an infectious disease specialist with Detroit’s Henry Ford Health System.

Dr. Allison Weinmann is involved in phase three clinical trials for Moderna's mRNA-1273 Coronavirus Efficacy (COVE) vaccine study. Henry Ford is participating in the national study, which has recruited 30,000 volunteers to receive either the vaccine or a placebo, and monitor the results for both safety and efficacy.

The U.S. Environmental Protection Agency finished the second phase of a new method for chemical pollution cleanup at a Superfund site in St. Louis, Michigan.

This site is 52 acres where the Velsicol Chemical plant once stood. It manufactured DDT, polybrominated biphenyls (PBBs), and chlorobenzene among other toxic chemicals.
