In the Gulf of Mexico, officials with the LLOG Exploration Company say a rupture in a pipeline south of Louisiana this month led to the Gulf’s largest oil spill since the 2010 Deepwater Horizon disaster. The spill dumped an estimated 672,000 gallons of oil into one-mile-deep water about 40 miles off the coast. Meanwhile, the Coast Guard has called off a search for two workers who went missing Friday after their oil barge exploded in waters off the coast of Port Aransas, Texas. The barge was carrying 133,000 barrels of crude oil, some of which spilled into the Gulf.
