mackinac straits

Enbridge has told state officials it's going to pick up broken equipment from the bottom of the Straits of Mackinac ahead of schedule.

Back in September, Enbridge was taking rock and sediment samples at the bottom of the Straits of Mackinac. That’s when a 45-foot piece of equipment known as a grout rod – or a drilling rod – broke off at the bottom of the Straits.

Michigan Governor Gretchen Whitmer says she's open to renew talks with Enbridge Energy about the future of its oil pipeline through the Mackinac Straits.

Last week, Enbridge – which is a Michigan Radio sponsor – asked the state Court of Claims to consider the legality of agreements it reached with former Governor Rick Snyder to build an oil pipeline tunnel.

Michigan’s attorney general has until June 27 to respond to Enbridge’s lawsuit.

Michigan Attorney General Dana Nessel says a law passed last year to build an oil pipeline tunnel beneath the Mackinac Straits is unconstitutional.

One of the first things Gov. Gretchen Whitmer did when she took office in January was to ask for an attorney general’s opinion on the law, which former Gov. Rick Snyder pushed through in the waning days of the legislature.

A new study predicts a major potential economic effect of an oil spill in the Mackinac Straits to the entire Great Lakes region.

The Line 5 oil pipeline which crosses the Mackinac Straits is operated by Enbridge Energy.  

Several environmental groups are stepping up their efforts against an expected plan to build a tunnel for an oil pipeline that passes through the Mackinac Straits.

A spokesman for Governor Rick Snyder says the state is still “reviewing studies and working through all possible options” for what to do with Line 5.

But environmentalists believe the governor has already decided.

UPDATED 5/25/18 at 2:13 pm.

A new poll by Lansing-based EPIC-MRA poll found 54% of Michigan voters want the Line 5 oil pipeline in the Straits of Mackinac to be shut down.

It also found that 87% of voters said they are concerned that the 65-year-old pipeline could have oil spill in Northern Michigan, while 64% said they are "very concerned."

Enbridge Energy, which is a corporate sponsor of Michigan Radio, owns and maintains Line 5.

A coolant spill in the Straits of Mackinac did not harm the Great Lakes. That’s according to the Coast Guard and Michigan Department of Environmental Quality.

Michigan’s economy would take a big hit from an oil spill in the Mackinac Straits, according to a new study.

A study by Michigan State University ecological economist Robert Richardson estimates Michigan’s economy would lose $6.3 billion if there’s a significant oil pipeline break in the Straits of Mackinac.

The study is based on a scenario where more than 2 million gallons of crude oil leaks from the Enbridge Energy Line 5 pipeline.  

An electrical cable that leaked hundreds of gallons of mineral oils into the Straits of Mackinac will be inspected – as soon as the weather clears up.

Unified Command is a team of local, state and federal officials that responded to the spill reported earlier this month. The owner of the cable line, American Transmission Company is also on the team.

The plan is to send a remotely operated vehicle (ROV) under the water to inspect the line.

Three small dents in Enbridge Energy's Line 5 pipeline are likely from the same vessel that caused damage to electrical cables in the Straits of Mackinac.

Enbridge told the state late Tuesday night that the damage poses no threat to the pipeline, although a previous independent analysis listed anchor damage as one of the largest risks to the line.

Officials say 550 gallons of potentially toxic coolant fluid have leaked from electric power cables that run underwater where Lake Huron and Lake Michigan meet.

The owner of the cables, American Transmission Company, says the fluid is a mineral-based synthetic oil used for insulation that can be harmful if released into the environment.

American Transmission says the leak was discovered after the two cables tripped offline Sunday evening. The cables have been taken out of service.

Governor Rick Snyder is rejecting a proposal to shut down an oil pipeline that runs beneath the Mackinac Straits.

Last month the Michigan Pipeline Safety Advisory Board (MPSAB), a panel created by the governor, urged Snyder to temporarily shut down Enbridge Line 5 until it can be inspected for gaps in the external coating and all the gaps are repaired.

But today, the governor says recent tests indicated there “is not a risk of imminent failure.”  

Tired of waiting for the state, environmentalists are offering their own plan for shutting down an oil pipeline that runs beneath the Mackinac Straits.

In recent years, concerns the aging pipeline could leak prompted calls from various groups to stop oil flowing through the pipeline. The Line 5 pipeline is owned by Enbridge Energy, which is a corporate sponsor of Michigan Radio.

A final state-commissioned report on alternatives to Line 5 is out.    People are looking for those alternatives because the pipeline runs under the straits of Mackinac, and a spill could be catastrophic.   The highly technical report from Dynamic Risk Assessment Systems claims the overall risk of a spill from Line 5 is very small.  Most people worry about the pipeline losing its protective coating, or metal fatigue caused by stresses from the strong currents, but the report claims the greater threat is a ship anchor striking the pipeline.    The alternatives considered range from an expensive $2 to $3 billion new pipeline that avoids the Great Lakes altogether to constructing a new section of the pipeline across the Straits in a trench or tunnel. That alternative would cost between $30 to 150 million, according to the analysis.

Michigan’s energy chief says Enbridge downplayed the significance of damage to the protective coating on its oil and gas pipeline that runs under the Mackinac Straits.

Parts of the coating were removed while workers installed safety anchors on a portion of Line 5 that runs beneath the Straits of Mackinac.

The patches where the metal was scraped bare are close to a foot in diameter. That's much larger than Enbridge initially reported.

A group hopes to get a ballot question before voters that would ban Enbridge from transporting oil through its Line 5 pipelines, which run under the Straits of Mackinac.

Attorney Jeffrey Hank is with the group, Keep Our Lakes Great.

Hank says while there are other efforts underway, including studies assessing the risks of the pipeline and alternatives to it, "we can't dawdle. After Flint and all these other lessons, we've seen we can't just sit around. So if the state doesn't do something, we're going to put the question before voters."

An oil pipeline running beneath the Straits of Mackinac could be shut down under a bill in the legislature.

The company that operates the pipeline insists it’s safe.

Nevertheless, State Senator Rick Jones wants a third party analysis of Line 5.

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.

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 natural gas liquids pipeline splits into two smaller diameter pipelines to make the underwater crossing.

Congress has ordered stronger safety measures for pipelines carrying oil and other fuels in the Great Lakes region.

The requirement is contained in a bill that cleared the Senate on Monday and the House last week. It now goes to President Barack Obama for his signature.

The measure re-authorizes a federal program that regulates 2.6 million miles of pipelines nationwide.

Sen. Gary Peters of Michigan says it designates the Great Lakes as an "unusually sensitive area," where pipelines must meet tougher standards for safe operations.

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.
