Line 5

Michigan Radio

MACKINAW CITY, MI (AP)--   Michigan regulators will take public comments on a proposal for more anchor supports in the Straits of Mackinac to bolster twin oil pipelines. 

Enbridge Inc. is asking the Department of Environmental Quality to allow installation of 48 additional supports for its Line 5 pipes. They would be attached to the pipes and screwed into the lakebed.

A public hearing is scheduled for Wednesday at 4 p.m. in Mackinaw City.

LANSING, MI (MPRN)--   Enbridge Energy has submitted a report to the state on possible alternatives to continuing to run an oil and gas pipeline on the bottomlands of the Straits of Mackinac. 

Neither of the alternatives would shut down the line.

Shutting it down is what environmental groups are calling for. Enbridge has proposed digging a tunnel 100 feet below the bottom of the straits, or encasing Line 5 in a trench covered with concrete and stone.

MACKINAC ISLAND, MI (MPRN)--   Environmental groups are using a large gathering of Michigan’s political and business leaders on Mackinac Island to pressure the state to shut down Enbridge Energy’s Line 5. 

Protesters were at the ferry docks to greet attendees of the Detroit Regional Chamber’s Mackinac conference.

Jim Lively is with a Northern Michigan environmental group. He says the line under the straits serves as a shortcut for moving fuel between points in Canada with little benefit to Michigan.

LANSING, MI (MPRN)--   Governor Rick Snyder has approved six-month ban on ships dropping anchor in the Straits of Mackinac. It’s a response to a mishap in April that caused a mineral oil spill and damage to Enbridge Line 5. 

There are advisories on maritime maps that say ships shouldn’t drop anchor in the straits, where there’s a risk posed by the Enbridge fuel line and other infrastructure. But it’s not a regulation. In April, a ship dragged an anchor across the bottom of the straits and ruptured a utility line and dented Line 5.

LANSING, MI (AP)--   The company that operates twin oil pipelines in the Straits of Mackinac says one of the lines suspected of being struck by a tugboat anchor was dented more than three-fourths of an inch.

Enbridge Inc. official Peter Holran told the Michigan Pipeline Advisory Board in Lansing Monday about the April 1 damage to the pipelines running between Lake Michigan and Lake Huron.

MACKINAW CITY, MI (AP)--   Oil is flowing again through side-by-side pipelines beneath the Straits of Mackinac.

Enbridge announced Monday afternoon it has restarted its Line 5, which was shut down over the weekend. The company blamed a power outage. Sens. Gary Peters and Debbie Stabenow of Michigan had pushed for a temporary shutdown because of high winds and heavy currents in the Straits of Mackinac.

Line 5 carries 23 million gallons of oil daily between Superior, Wisconsin, and Sarnia, Ontario.

ST. IGNACE, MI--   Enbridge suspended operation of its Line 5 oil pipeline Sunday due to severe weather.

US Senator Gary Peters pressed the company to take the action after lake swells in the Straits of Mackinac topped 12 feet. Under an agreement with Governor Snyder, Enbridge reportedly said it would shut down the line if waves exceeded 8 feet.

Last week Enbridge said three dents were discovered in Line 5. Officials wonder if they were caused by whatever damaged an American Transmission Company utility line and dumped 600 gallons of dielectric fluid into the water.

LANSING, MI (AP)--   State officials have given Enbridge Inc. permission to install 22 more anchor supports along twin pipelines at the bottom of the Straits of Mackinac.

The Michigan Department of Environmental Quality issued a permit last week allowing the supports for Line 5.

Enbridge says it's a "proactive" step to fasten the pipelines to the lake bottom and keep them in place when currents erode dirt beneath them.

The underwater pipes are part of a line that carries 23 million gallons of crude oil daily between Superior, Wisconsin, and Sarnia, Ontario.

LANSING, MI (MPRN)--   Governor Rick Snyder will allow oil to continue to flow through a controversial pipeline beneath the Straits of Mackinac. 

Last month a state panel created by the governor recommended temporarily shutting down Enbridge’s Line 5. That's until problems with the pipeline’s external coating could be addressed.

Monday Governor Snyder rejected that idea.  He says tests show the oil pipeline is not at “imminent” risk of failing. He says shutting the pipeline down likely would create a propane “supply crisis.”

TRAVERSE CITY, MI (AP)--   State officials have released a final analysis of options for the future of a controversial oil pipeline that runs beneath the Straits of Mackinac. 

The report by the Canadian consulting firm Dynamic Risk lists six alternatives.

Among them is continued operation of Enbridge Inc.'s Line 5, which runs from Superior, Wisconsin, through northern Michigan to Sarnia, Ontario. The segment that crosses the Straits of Mackinac is divided into two lines.
