The Napa Special Investigations Bureau was formally established on March 1, 1976, through a state grant funded by the California Office of Criminal Justice Planning. In 1979, the grant funding had expired; however, Napa County and the Cities of Napa, St. Helena, and Calistoga opted to maintain the funding for NSIB, to continue narcotics investigation and enforcement efforts. The Office of Emergency Services continues to fund one agent and one probation officer positions within the NSIB task force and one Deputy District Attorney assigned to vertical prosecution of NSIB investigations.

NSIB continued to operate under the direction of a NSIB Governing Board comprised of the chief law enforcement administrators of participating law enforcement agencies. The agencies were the Napa County District Attorney’s Office, the Napa Sheriff’s Department, Napa Police Department, St. Helena Police Department, Calistoga Police Department, the California Highway Patrol, and the Napa County Probation Department.

In 1988, the NSIB Governing Board and the California Department of Justice, Bureau of Narcotic Enforcement, entered into a Memorandum of Understanding, an inter-agency agreement where, under the general administrative control of the NSIB Governing Board, BNE would assign a Special Agent Supervisor to assume the direct management of NSIB. As a result of the agreement, NSIB became one of 25 other county narcotic task forces participating in the BNE’s Statewide Regional Task Force program. There are now 33 regional task forces statewide.

In January 2000, the NSIB Governing Board unanimously agreed to include the Napa County Probation Department as a member of NSIB.

Under the task force program, BNE and NSIB have combined their respective efforts and resources primarily to conduct criminal investigations and enforcement activities aimed at combating the illegal manufacturing, trafficking, and use of controlled substances throughout Napa County. The alignment between NSIB and BNE also provides the task force with statewide linkage to BNE regional offices, regional task forces, Department of Justice training programs, and Department of Justice investigative, intelligence, and analytical services.
