Maryland Gov. Parris Glendening has selected Charles Fox, a former senior EPA official now working with the Chesapeake Bay Foundation, as secretary of the state Department of Natural Resources effective Sept. 5.

He replaces Sarah Taylor-Rogers who resigned in August after serving in the post for two years.

Fox was the EPA assistant administrator for water in the Clinton administration. Earlier this year, he joined the CBF as a senior policy adviser. At the EPA, he oversaw the nation’s programs for protecting water quality, including wetlands, watershed protection, the setting of water quality criteria and the development of numerous water rules.

At the CBF, Fox helped to develop a multibillion-dollar cleanup campaign for the Bay. He produced an estimate for the CBF that it would cost $8.5 billion over the next decade to accomplish the goals of the Chesapeake 2000 Agreement.

“Mr. Fox has achieved national prominence for his innovative and successful work to protect and preserve Maryland’s and the nation’s natural resources,” Glendening said in a statement. “He will lead an aggressive effort to preserve our remaining green infrastructure and will be a dynamic and critical member of our Smart Growth team.”

Before going to the EPA, Fox was assistant secretary at the Maryland Department of the Environment. He has also worked for American Rivers, Friends of the Earth, and the Environmental Policy Institute.
