Hazardous materials responders work on sections of a pipe near an oil pipeline rupture along the Alameda County-San Joaquin County border near Tracy, California, cleaning up a spill reported to be as much as 21,000 gallons. The leak in the underground pipe, which was reported by Shell Pipeline Co. after a line between Coalinga (Fresno County) and Martinez lost pressure, was spilling crude oil into the soil but was not near any waterways where the problem would escalate. The oil release was visible on the ground in a 250-by-40-foot section, San Joaquin County officials said.
