Two top environmental agencies in the Chesapeake Bay watershed are about to get new leadership.

John Griffin, secretary of the Department of Natural Resources, will be moving on to the chief of staff position for Gov. Martin O'Malley's administration. Griffin has been secretary since March 2007 and was the chair of the governor's transition team for environment and natural resources. Griffin also held the job of secretary during Parris N. Glendening's administration, from 1995 to 1999.

Stepping up to the position of Secretary of Natural Resources will be Joe Gill, who had been deputy secretary. Gill served as the DNR's primary counsel for 14 years before his appointment to deputy secretary in 2010.

Gill's promotion clears the way for Frank Dawson, a 29-year agency veteran, to step up into the role of deputy secretary, from assistant secretary. And it allows Dave Goshorn, a 21-year veteran who currently runs the department's sustainability office, to step in as assistant secretary.

"Together, Joe, Frank and Dave are a management dream team," Griffin said in a press release. "With 66 years of policy development and resource management experience specific to DNR between them, I can't imagine a better scenario for the future management of — and I guess this is this last time I'm allowed to say this — the best agency in state government."

Michael Krancer, who had been secretary of Pennsylvania's Department of Environmental Protection since January 2011, resigned from his post April 15. Krancer has returned to his Philadelphia home, where he will practice law. He will chair the energy, petrochemical and natural resources practice at Blank Rome, a Philadelphia law firm.

Pennsylvania Gov. Tom Corbett has not named a permanent replacement yet, but he has asked his deputy chief of staff, E. Christopher Abruzzo, to serve in an acting capacity. Abruzzo has spent most of his career as a prosecutor.
