Wisconsin Public Radio reports a vehicle crash in Illinois has disrupted pipelines that carry crude oil from the Alberta tar sands to refineries in the Midwest. The Enbridge pipeline moves 318,000 barrels of oil a day. A spokeswoman could not say how the disruption might affect refineries in the region.

Enbridge, a Calgary, Alberta-based petroleum company, wants to build a new 500-mile pipeline to transport more crude from northwest North Dakota to Superior, Wis., Forum Communications reports. Company officials say the Sandpiper Pipeline could move about 225,000 barrels per day. If the project is approved, the earliest it could go into service would be late 2015.

Enbridge Energy just completed its Alberta Clipper pipeline a couple of years ago. But the company already wants to upgrade the line, which carries Canadian oil across northern Minnesota to Superior. A plan for the $40 million project was filed Monday with the Public Utilities Commission.

Petroleum and the chemical used to clean up the 2010 Gulf oil leak have shown up in the eggs of pelicans that nest in western Minnesota. Swift County is home to North America's largest colony of American White Pelicans, which winter in the Gulf of Mexico. Biologists will monitor how the chicks hatched from polluted eggs develop.

521 people live in Clearbrook, Minnesota. Fourteen percent of the country's crude oil flows through pipelines under their feet. Clearbrook is a terminal for pipelines heading from Canada and North Dakota to refineries in the Twin Cities, Superior, and Chicago. A planned expansion will soon allow more North Dakota crude to flow through the junction.

An Xcel Energy spokeswoman says low oil pressure in the plant's turbines triggered an automatic shutdown over the weekend. The company says the safety system functioned as designed and that no one was in danger.

The 1,300-mile project would cost more than $1.5 billion and could ship 200,000 barrels of crude daily from western North Dakota to the nation's biggest storage terminal. Construction on the pipeline could begin as early as next year and be complete by 2015.
