"New Orleans Stench May Be Linked to Exxon Refinery Leak: Coast Guard"

"A 'rank' odor that has spread across parts of greater New Orleans may be linked to a leak from the 192,500-barrel-per-day Chalmette refinery, the U.S. Coast Guard investigating the smell said on Thursday."

"Chalmette, a joint venture between Exxon Mobil Corp and Venezuela's national oil company Petroleos de Venezuela SA (PDVSA), reported a leak early Wednesday morning but it had been quickly contained at the plant, the Coast Guard said.
 

'Chalmette Refinery has worked with (the Louisiana Department of Environmental Quality) and Coast Guard response teams most of the day to survey and evaluate all potential sources of odors in the area,' the Coast Guard said."
