Environmental Protection Agency Administrator Lisa Jackson will resign from her post after President Barack Obama delivers his State of the Union address next month. "So I will leave EPA confident the ship is sailing in the right direction, and ready in my own life for new challenges, time with my family, and new opportunities to make a difference," Jackson said. During her time as head of the EPA, energy producers questioned the agency's emissions-reduction efforts and its measures to increase ethanol levels in gasoline without fully understanding potential effects on engines.
