According to the Associated Press, internal documents show that budget cuts and a lack of leadership contributed to significant safety problems at BP PLC''s Texas City plant, the site of last year''s deadly explosion, federal investigators said. In preliminary findings, the U.S. Chemical Safety and Hazard Investigation Board said BP management knew about maintenance, spending and infrastructure problems well before the March 2005 blast that killed 15 people and injured more than 170. BP has been beset by troubles with its North America operations since the blast.
