Very quickly, such an agency would not require much in the way of resources but the commitment of the industry, the government politically, and the regulators to accept an independent agency that functions in a quasi-judicial fashion and cannot be influenced by the money of the industry.
I would say that it would cost approximately—I'm guessing here—maybe $20 million annually. It's not a big sum, when you consider the billions of dollars of profit that are at stake and the thousands and thousands of lives that are being lost without such a board.
