A prison diving program was first established in 1970 and lasted for 33 years, before the program was eliminated during budget cuts in 2003. On December 1, 2006, the commercial diving center at the California Institution for Men (CIM) in Chino was reestablished as part of the renewed rehabilitation efforts of the California Department of Corrections and Rehabilitation.
