The US Chemical Safety Board or CSB, is launching an investigation into the root causes of the BP oil spill that killed 11 workers in what has become the worst environmental disaster in US history.
The CSB said in a letter to U.S. House Energy and Commerce Committee leaders, that the agency will examine what led to the April 20 explosion on the Deepwater Horizon oil rig.
The CSB said the investigation will examine safety cultures involved and the effectiveness of relevant laws, regulations and industry standards.
The agency will tap into its 847-thousand US dollar emergency investigative fund and ask for more money to cover its costs.
Meanwhile, a White House spokesman made critical comments of BP CEO Tony Hayward. He pressed the energy company to take responsibility for the "mess they've made."
Bill Burton, White House Spokesman, said, "You know look,if Tony Hayward wants to put a skimmer on his yacht and bring it down to the Gulf, we would be happy to have his help, but what's important isn't what Tony Hayward is doing in his free time, it's what BP is doing to take responsibility for the mess that they've made."
Adding to an already damaged image, the BP CEO was reported to have watched a yacht race off the English coast on Saturday. His move has sparked a new controversy in the United States as his company struggles to plug its huge oil leak in the Gulf of Mexico.
