anchor supports

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 (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--   The Michigan Department of Environmental Quality is seeking comment on an Enbridge Energy plan to add supports to its pipeline under the Straits of Mackinac.  

The 65-year-old Line 5 transports oil and liquid natural gas between the Lower and Upper Peninsulas.  When it was constructed the company’s engineers said the pipes could safely run up to 140 feet between anchor supports, but Enbridge’s easement agreement with the state requires supports at least every 75 feet.
