The State Commission of Corrections will still have to approve all the new policies and procedures at the jail before granting them a certificate of occupancy. The Sheriff is hoping to open the jail between the third and fourth week of April. Every corrections officer that works in the jail must be trained to perform any work throughout the facility.
