In this Monday, April 1, 2013 file photo, oil covers the ground around a slide in Mayflower, Ark., days after a pipeline ruptured and spewed oil over lawns and roadways. The Pegasus pipeline ruptured last March in Mayflower, spilling thousands of gallons of oil into the area. Exxon Mobil is denying claims from plaintiffs in an oil spill lawsuit that it made all information about the maintenance and repair of an oil pipeline secret. The oil giant has blamed the rupture on manufacturing defects. (AP Photo/Jeannie Nuss, File)
