GRAND MARSH, Wis. (WZZM) -- Enbridge, the company that spilled more than 800,000 gallons of crude oil into the Kalamazoo River two years ago, had another spill along its pipelines this weekend. This time, the spill was in Grand Marsh, Wisconsin.

The company says that about 1,200 barrels of crude oil was released at the Wisconsin site, but that emergency crews sent to the site on Friday afternoon have the spill contained.

"It has basically kind of soaked into the ground around or near the pipe," said Lorraine Little, who works for Enbridge. "In other words, there isn't any pooling oil or there isn't any oil moving at all. It's all really contained in the area around the pipe and within our easement."

Enbridge detected a pressure drop Friday and shut down the line to isolate it. The particular line that leaked mainly transports crude oil to refineries in Chicago.

The July 2010 spill in Marshall is the worst on-shore oil spill in United States' history, with cleanup costing more than $800 million so far. A recent report claims Enbridge knew about the pipeline problems five years before the disaster, but the oil company says that it has made many safety improvements since that incident.

Enbridge says that it is working with emergency officials and the appropriate regulators. The cause of the leak is still being investigated.
