The oil spill into the Gulf of Mexico during the Deepwater Horizon spill was awful. 
Apparently, the EPA requires the use of an oil dispersant known as Corexit. Recent studies by Georgia Institute of Technology and Universidad Autonoma de Aguascalientes (Mexico) found that the oil plus dispersant was found to be about 52 times more toxic than oil alone.

Because no private property or profit-and-loss mechanism is involved, the government is fundamentally unable to avoid these blunders. 

But rather than hold the corporation fully liable and responsible for its actions, the EPA will just as likely be given increased funding and/or oversight. Because increased funding and/or oversight do not resolve the fundamental lack of central planning to calculate, it will not prevent the EPA from making these same mistakes in the future.
