This whole BS regarding approved blend stock for certain pump equipment is a complete farce and was probably in illegal and potentially under the table payment made by the oil industry back in 2008 to the underwriters laboratory.

It's downright extortion.

This is a step in the right direction fixing what has to be the most textbook example of regulatory capture.
