In a new report released today, the National Wildlife Federation took a look at data on currents in the Straits of Mackinac. That’s where Enbridge’s twin pipelines run along the bottom of Lake Michigan.

Mike Shriberg is the executive director of the Federation’s Great Lakes office.

“What this report shows is that there are additional stresses on this pipeline beyond what it was designed for," he says.

It was April of 2010 when Enbridge Line 6b ruptured, spilling more than a million gallons of Canadian heavy crude oil into a creek near Kalamazoo.

It was the largest inland spill in United States history.

That spill gave Michiganders a very good reason to sit up and pay closer attention to the nearly 3,300 miles of hazardous liquid pipelines that weave through our state, particularly Enbridge Line 5, which runs in the Straits of Mackinac.

An Enbridge work plan document shows areas where a protective coating around its twin oil pipelines running through Lake Michigan might be failing.

Enbridge posted the document on its website last fall. It shows 18 specific areas along the pipelines where there is “coating delamination.” The 64-year-old pipelines were installed with a coating around them to protect for corrosion.

The Enbridge Line 5 oil pipeline stretches from Superior, Wisconsin to Sarnia, Ontario. It crosses northern Wisconsin into the Upper Peninsula of Michigan and then under the Straits of Mackinac which connects Lake Michigan and Lake Huron.

The path of the 64-year-old pipeline also crosses the Bad River Reservation in northeast Wisconsin.

According to Robert Blanchard, the chairman of the Bad River Band Tribal Council, the easement under which Enbridge has been operating the pipeline on the Bad River Reservation expired in 2013. Last week, the council voted not to renew the easement, which could eventually lead to removal of the section of the pipeline that crosses through the reservation.

Legislation has been introduced in Congress calling for a shut down of Enbridge's Line 5 if a federal study shows that it threatens the Great Lakes.

Line 5 is the controversial, 63 year-old underwater pipeline in the Straits of Mackinac.

The legislation would require the federal government to conduct a study to determine the economic and environmental risks to the Great Lakes from possible failures of Line 5, and it puts a 12 month deadline on completing the study.

Republican Dave Trott and Democrat Debbie Dingell are co-sponsors of the legislation.

The Michigan Department of Environmental Quality says Enbridge Energy can install four additional anchor supports on the Line 5 pipeline that runs beneath the Straits of Mackinac.

The MDEQ issued a permit for the four supports to maintain the integrity and safety of the pipeline.

Enbridge still needs a permit from the U.S. Army Corps of Engineers.

Enbridge Energy’s Line 5 goes right under Lake Michigan. It splits into two pipelines at the Straits, and it was recently announced that the supports that hold the pipeline in place are not in compliance with a 1953 easement agreement with the state.

Some of the supports for Enbridge Energy’s Line 5 pipelines under the Straits of Mackinac are not as close together as they should be, according to State Attorney General Bill Schuette.

That’s gotten the company into some hot water with the state of Michigan.

Supports help keep the pipeline stable as it is buffeted by the powerful currents of the Straits. 

Enbridge told the state in 2014 the pipeline has supports every 75 feet, as required by the state's 1953 easement.

You probably remember hearing about fines levied against Enbridge for the 2010 Kalamazoo River oil spill before. You're right. You did.

The company paid fines and settlements to the state of Michigan, fines to tribes, and fines to the U.S. Department of Transportation, and settlements with nearby homeowners and landowners.

The state of Michigan has contracted with Det Norske Veritas to conduct a risk analysis of Enbridge Energy Line 5, two oil pipelines that run under the Straits of Mackinac.

A separate consultant, Dynamic Risk Assessment Systems, will study the alternatives to keeping the aging pipelines open.

Environmental groups say a failure of the pipelines would be a catastrophe for the Great Lakes.

Officials with Enbridge Energy say they’ll spend $7 million over the next two years to buy new clean up tools in case there’s a spill along its Line 5 pipeline.

 

There has been a lot of controversy surrounding Line 5 where it crosses at the Straits of Mackinac. At the Straits, the oil and liquid natural gas pipeline splits into two smaller diameter pipelines to make the underwater crossing.

For the next few months, environmentalists are traveling the length of an oil pipeline in Michigan. They hope to convince government officials to shut it down.

Shouting “Remember the Kalamazoo”, protesters made their position clear during a mock oil spill drill along the St. Clair River a few days ago. 

They want Enbridge’s Line 5 pipeline to shut down. The pipeline snakes its way through Michigan, including crossing the Mackinac Straits.

“Pollution doesn’t know borders,” says Randy Emerson, with the Council of Canadians, “so what happens here can affect us.”

People who want Enbridge Energy's Line 5 shut down plan to make it an issue at next week's policy conference on Mackinac Island.

The oil pipeline runs under the Straits of Mackinac, near the island.

Enbridge Energy is the company responsible for the largest inland oil spill in U.S history, which happened when the company's Line 6B ruptured near Marshall, Michigan in 2010. 

The massive oil spill dismayed a lot of people, including Republican State Sen. Rick Jones. He says Michigan can't risk having a spill in the Great Lakes.

U.S. and Canadian government agencies took part in a mock oil spill drill along the St. Clair River just south of Port Huron today.

With temperatures in the low 80s and a light breeze, it was a lovely day to respond to a fake disaster.

But while a few first responders spent a sunny day on boats in the river, most of the more than 200 people taking part in the exercise spent their time indoors dealing with a scenario for a fictional disaster that included the need to corral thousands of barrels of oil leaking from Enbridge’s Line 5 pipeline.

Government agencies will practice responding to an oil spill from a pipeline crossing the St. Clair River tomorrow. 

The pipeline passes beneath the St. Clair River just south of Port Huron.

The drill will involve a simulated 13-minute, 5,000-barrel oil spill. The exercise will involve boats in the river and absorbent booms in the water, all to corral and collect fictional oil leaking from the pipeline.

The drill involves government agencies and the pipeline’s owner, Enbridge.

The National Wildlife Federation is suing a federal agency over safety concerns about an oil pipeline running under the Straits of Mackinac.

Line 5 is operated by Enbridge Energy, the company responsible for a massive oil spill in the Kalamazoo River in 2010.

The state of Michigan, environmental groups, and reporters like myself have been asking Enbridge for more specific information about the condition of the pipelines for more than two years now.

The company has released limited information in the past, but stopped short of releasing detailed reports that show the condition of the pipelines. When it comes to this kind of information, the company holds all the cards.

There are some new questions bubbling up concerning a decades-old oil spill in the Upper Peninsula.

Around 1980, Canadian oil transport company Enbridge discovered its Line 5 oil pipeline had sprung a leak and spilled an estimated five barrels of oil in the Hiawatha National Forest.

Yes, that’s the same Line 5 whose twin pipelines run under the Straits of Mackinac.

A new bill in Congress would shut down an oil and gas pipeline beneath the Straits of Mackinac, if a study shows it's a significant risk to the Great Lakes.

Michigan Congresswoman Candice Miller introduced the Great Lakes Pipeline Safety Act on Wednesday.

The legislation calls for a comprehensive analysis of the environmental and economic threat that Enbridge's Line 5 pipeline poses to Great Lakes waters.

There's a more-than-60-year-old underwater pipeline that crosses the Straits of Mackinac. It's called Line 5, and is operated by Enbridge, the company responsible for the largest inland oil spill in U.S. history. The 2010 spill resulted in the release of about a million gallons of crude oil into the Kalamazoo river. 

A new film follows a pair of Grand Rapids natives on their "fossil fuel-free" journey along the pipeline's 500-mile route. It's called Great Lakes, Bad Lines. 

Filmmaker Paul Hendricks joins us to talk about the film. 

A postcard from 1953 shows Line 5 being installed in the Straits of Mackinac. The group says it's proof the easement wasn't followed in the first place. Enbridge says that's not true.
Oil & Water Don't Mix

Several environmental groups and tribes say Enbridge Energy is operating its oil pipelines under Lake Michigan illegally. They sent a letter to Governor Snyder, Attorney General Bill Schuette, and others calling for the immediate shutdown of the twin pipelines.

The Oil & Water Don’t Mix campaign put together a list of what they say are eight violations of the state’s easement with Enbridge.

Back in 1953, the state allowed the pipelines to cross the Straits of Mackinac under this legal contract.

From the UM Water Center report

Enbridge Energy has maintained that their twin oil and natural gas liquid pipelines under Lake Michigan at the Straits of Mackinac are safe.

But what if one of them did break open? Where might the oil go?

Today, the University of Michigan’s Water Center released new computer simulations to help answer that question.

David Schwab is a hydrodynamics expert with the Water Center.

“I don’t know any place where the currents are as strong, and change direction as quickly, and as frequently as in the Straits of Mackinac,” Schwab said.

Enbridge Energy’s Line 5 goes right under Lake Michigan at the Straits of Mackinac.

At the Straits, it splits into two pipelines. Both pipelines are 63 years old (they were installed in 1953).

Right now, we don’t have all the information about the condition of those pipelines. As we’ve reported many times, Enbridge holds all the cards. The company has shared some information with the public, but not a lot.

U.S. Senator Gary Peters (D) has two big projects on his plate in an effort to strengthen protections for the Great Lakes and provide funding for the city of Flint in the wake of the water crisis.

The U.S. Senate recently gave unanimous approval to a funding bill that includes important protections for the Great Lakes. The bill re-authorizes the Pipeline and Hazardous Materials Safety Administration (PHMSA), which is the federal agency that oversees pipelines.

There's been an ever-increasing drumbeat of alarm over the more than 62-year-old Enbridge Line 5 running under the Straits of Mackinac carrying some half a million barrels of oil or liquid natural gas.

Well, if pipelines built in 1953 have you worried, how about pipelines built in 1918?

The owner of the 98-year old pipelines has asked the State Department to update usage permits on the pipes that run under the St. Clair River between Marysville and Sarnia, Ontario.

Recently released information about the condition of Enbridge’s Line 5 oil pipelines in the Straits of Mackinac shows some signs of corrosion. But company officials continue to say the twin pipelines running under Lake Michigan are safe.

An environmental group says oil pipelines running beneath the Mackinac Straits could be shut down without disrupting oil and propane supplies in Michigan.

Environmentalists say there is enough capacity on other pipelines skirting the Great Lakes to reroute the crude oil currently flowing through Line 5. 

The report says at least 90% of Line 5's oil goes to Canadian refineries, so it's not essential for the Marathon refinery in Detroit.

There are many Michiganders feeling uneasy about the idea of those 62-year-old twin oil pipelines running along the bottom of the Straits of Mackinac.

The aging Line 5 can carry 540,000 barrels of oil and natural gas liquids each day.

Enbridge has made promises to keep the pipeline maintained and said it’s got an emergency response team in place, but there’s a complicating factor that no one can control: big, turbulent waves.
