OSHA wants to fine BP $87 million for the deadly blast after it found hundreds of violations involving pressure-release systems at the refinery. BP is fighting the fine and says it has overhauled safety procedures and is spending $1 billion to upgrade and modernize the 76-year-old plant.
BP has already settled hundreds of death and injury related lawsuits out of court.
Among the commemorative events today will be a moment of silence at 1:20pm to mark the exact moment of the explosion.
