The Emergency Response and Preparedness (ERP) Division is a division within the Sheriff's Office, and when originally created, was an expansion of Oakland County Emergency Management in the aftermath of the September 11, 2001 terrorist attacks.
The division's primary responsibilities include all homeland security initiatives, the Communications Unit, the Training Unit including all range operations, the Civil Unit, and the Concealed Weapons Board.
This division coordinates functions with the other county law enforcement agencies, the State Police, the FBI, USSS, Customs, INS, and the U.S. Attorney's Office.
