Former Pennsylvania Department of Environmental Protection (DEP) Secretary John Hanger has joined the Eckert Seamans Cherin & Mellott law firm in Harrisburg, PA. Hanger will support the firm’s practices in the areas of energy, utility and environment, concentrating in alternative energy, clean transportation infrastructure, energy efficiency, competitive energy markets and smartgrid, according to the firm. Hanger, a former CEO of Citizens for Pennsylvania’s Future and a former member of the Pennsylvania Public Utility Commission, earned his J.D. from the University of Pennsylvania School of Law and his undergraduate degree from Duke University. He left DEP last month after a tenure of more than two years during which activity in Pennsylvania’s Marcellus Shale mushroomed.
