On November 8, 2013, Heather Zichal, a longtime Obama Administration official and President Obama's top energy and environment advisor since 2011, left her position to pursue other opportunities. Zichal's next steps are not publicly known.
Zichal, a former Capitol Hill staffer, was an important supporter within the Administration of policies, including the RFS, designed to support the development and commercialization of biofuels and renewable chemicals. She will be replaced by her former deputy, Dan Utech, who is also a former Capitol Hill staffer. Utech will continue Zichal's work, including seeing the President's Climate Action Plan move forward.
