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.

Plans are underway for a natural gas company to construct a pipeline under the St. Clair River into Canada, stretching some 1,500 feet.

More from the Associated Press:

"A bike path in Marysville will be closed to the public as Bluewater Gas Storage LLC conducts the work. The project is expected to last about a month. The bike path will be used as a staging area, rather than using people's yards or driveways."
