Wisconsin oil spill is Canadian firm’s worst since 2010 disaster

ANN ARBOR, Mich. — Enbridge, a beleaguered Canadian oil pipeline company, has spilled more than 50,000 gallons of light crude oil in rural Wisconsin —  shortly after the company said it had implemented safety reforms after a massive 2010 spill in Michigan.

Officials for Alberta-based Enbridge Inc., one of the United States’ most vital suppliers of Canadian oil, said Friday’s spill has been contained by cleanup workers,  who are now trying to repair and restart the 24-inch pipeline known as Line 14, which carries more than 300,000 barrels a day.

The incident is another black mark for an ambitious energy company ridiculed earlier this month by U.S. safety officials, who likened Enbridge workers  to the Keystone Kops. The comparison came after an investigation of a broken pipeline that released more than 800,000 gallons of heavy crude near Marshall, Mich. — one of the largest inland oil spills in U.S. history and certainly the most expensive.

The new spill, in sparsely populated Adams County, Wis., forced the evacuation of two homes. It is the company’s worst spill since the 2010 disaster, and it drew the ire of U.S. Rep. Ed Markey (D-Mass.), ranking member of the House Natural Resources Committee.

“Enbridge is fast becoming to the Midwest what BP was to the Gulf of Mexico, posing troubling risks to the environment,” Markey said in a statement. “The company must be forthcoming about this entire incident, and deserves a top-to-bottom review of their safety culture, procedures and standards.”

‘Frac sand’ sediment spills into St. Croix River

ST. PAUL, Minn. (AP) — A spill at a sand mining facility in Wisconsin has dumped an unknown amount of sand and other sediment into the St. Croix (kroy) River and wetlands near the Minnesota border.

Wisconsin DNR officials tell Minnesota Public Radio News it’s too soon to know how much damage was done.

Conservation officials learned of the leak on April 22, when a hiker reported seeing cream-colored water in a creek flowing to the St. Croix River. DNR investigators traced the murky water back to a sand mining facility operated by Maple Grove-based Tiller Corp., where they located a leak in a holding pond.

The sand is mined for use by the petroleum industry to help extract underground natural gas and oil supplies in a controversial practice called hydraulic fracturing, or fracking.
