Grumbles announced the resignation to the ADEQ staff in an email Oct. 28.
“I’m sad to say I’ll be leaving this great agency and grand state before the end of the year. It’s all about family and right now my family needs are re-directing me back East,” Grumbles wrote in the email.
In the email, Grumbles did not say when his last day would be. ADEQ spokesman Mark Shaffer said Grumbles had meetings scheduled through early December.
The resignation announcement also did not mention who Grumbles’ successor would be. He said deputy director Henry Darwin and other department managers would focus on “ensuring the transition is as smooth as possible.”
Grumbles was in Washington, D.C., following the announcement and could not immediately be reached for comment. Sources familiar with the situation told the Arizona Capitol Times that the director’s wife and children already moved back to Washington.
Prior to his appointment by Gov. Jan Brewer in March 2009, Grumbles served as an assistant administrator for the U.S. Environmental Protection Agency’s Office of Water.
