"U.S., Arkansas Sue Exxon Over Pegasus Pipeline Spill"

"The U.S. Justice Department filed a joint lawsuit with Arkansas on Thursday against oil producer Exxon Mobil Corp over the pipeline spill in March of thousands of barrels of heavy Canadian crude oil in a suburban neighborhood."

"The 95,000 barrels per day Pegasus line has been shut since spilling the oil in Mayflower, Arkansas, where cleanup operations continue. U.S. oil pipelines rarely spill in towns.

The Justice Department said it is seeking civil penalties against Exxon under federal law."
