Chevron Corp. and Transocean Ltd. are being sued for $22 billion in environmental damages in Brazil, double initial claims, after a federal prosecutor filed a second lawsuit over oil spills off the nation’s coast, according to Bloomberg. Chevron committed “a series of errors” which led to the March spill at Frade, the second incident at the offshore oil project, the federal prosecutors’ office said yesterday. Prosecutor Eduardo Santos de Oliveira is also seeking to halt operations at Frade and block San Ramon, California- based Chevron from transferring profits from Brazil. “The oil spill at the Frade field hasn’t been contained,” Oliveira said.
