The DEP’s Deputy Commissioner, Steve Lawitts (who, if you remember, was biking through Amsterdam when former Commissioner Emily Lloyd announced her resignation), has been appointed Acting Commissioner of the DEP.
He previously worked for the Department of Sanitation and currently retains his post as Executive Director of the Water Board. (UPDATE 4/21/09: He is also a board member on the Municipal Water Finance Authority. Now all he has to do is get elected mayor and he could control every aspect of water in NYC!)
