Los Angeles Gasoline at Two-Month Low on Tesoro Deal, Supplies

California-blend gasoline in Los Angeles fell against futures for the second day after Tesoro Corp. reached an agreement with union workers at the Golden Eagle refinery and U.S. West Coast gasoline supplies rose.

The United Steelworkers Local 5 at the 170,000-barrel-a-day Golden Eagle plant voted yesterday to accept a settlement offer, becoming the last of the company’s sites to agree on a deal and avert a strike. Tesoro had said the refinery, its largest, would become a terminal during a work stoppage until new personnel could be trained to operate it.

“We want to commend Local 5’s bargaining committee for their hard work in obtaining an agreement and to the membership for their solidarity,” Lynne Hancock, a spokeswoman for the United Steelworkers in Nashville, Tennessee, said in an e-mail yesterday.
