BELLE CHASSE, LA - JUNE 4: An oil tanker is seen docked at the ConocoPhillips Alliance Refinery June 4, 2008 in Belle Chasse, Louisiana. The refinery, located in Plaquemines Parish, processes 247,000 barrels of crude oil per day. Oil production suffered significant damage in the state by Hurricanes Katrina and Rita but high oil prices have driven the value of Louisiana's petroleum and coal exports up 127 percent. Petroleum and coal exports totaled $2.5 billion during the first quarter of 2008 compared to $1.1 billion in the first quarter of 2007. (Photo by Mario Tama/Getty Images)
