President Barack Obama on Monday announced his intention to nominate Jon Cannon for Deputy Administrator of the Environmental Protection Agency, a position that will play an important role in implementing the Renewable Fuels Standard.

Cannon is currently a professor of environmental law as well as the director of the Environmental and Land Use Law Program at the University of Virginia. He also served at the Environmental Protection Agency during three previous administrations – Reagan, George H.W. Bush, and Clinton – eventually rising to general counsel.

Cannon must still be confirmed by the Senate.
