A Pittsfield Township man who has a history of drunken driving is facing charges again.

Derek Edward Schummer, 20, is charged with operating while intoxicated third-offense, Washtenaw County court records show.

He is accused of driving drunk about 12:45 a.m. July 24 near the intersection of Mary and Packard streets in Ann Arbor. A blood sample sent to a state police lab revealed that he had a blood-alcohol level of 0.12, records show. In Michigan, it's illegal to drive with a blood-alcohol level of 0.08 or higher.

Ann Arbor police could not be reached for comment Friday for further details. Schummer was scheduled to be arraigned Friday afternoon.

If convicted, he faces a minimum of 30 days in jail.
