"U.S. Board Issues Subpoena on Offshore Platform Blast"
"A U.S. industrial accident investigative board served Black Elk Energy with a subpoena on Monday, seeking information about last week's offshore Gulf of Mexico oil platform explosion that left one worker dead and another missing."
"Spokeswoman Hillary Cohen said the U.S. Chemical Safety and Hazard Investigation Board, which investigates chemical spills, refinery explosions and other industrial accidents, will decide whether to launch a probe into Friday's blast once Houston-based Black Elk responds to the subpoena.
The company has until November 30 to respond, Cohen said. The CSB has authority to subpoena witnesses, but not to issue fines or citations.
The U.S. Bureau of Safety and Environmental Enforcement (BSEE), which regulates offshore oil and gas drilling and production, is investigating the blast."
