A top Illinois Department of Natural Resources official is the latest administrator to leave the agency.  The Springfield bureau of Lee Enterprises newspapers reports Tony Mayville was fired Monday from his position with the DNR’s Office and Mines and Minerals.  The Du Bois man says his unsuccessful bid for an Illinois House seat was carried out before the DNR’s chief cleared him to run.  Mayville says his handling of campaign donations from a coal company also was a factor.  Mayville’s departure follows the resignation of one director who attended professional fishing tournaments while on sick leave.  And the agency’s acting director of Mines and Minerals quit after revelations a campaign fund he controlled accepted contributions from a coal company.  IDNR confirms Mayville’s departure but won’t elaborate.
