(a) At the request of the board of supervisors of any county that is adjacent to another state, the county sheriff shall negotiate with the appropriate officials of the adjacent state to contract pursuant to the authority of Article III of a compact executed under Section 11189 or 11190 for the confinement of county jail prisoners in corresponding facilities located in the adjacent state. The sheriff shall determine that the corresponding facilities are a suitable place of confinement of prisoners submitted to his or her custody and shall at least annually redetermine the suitability as a precondition to any contract under this section. In determining the suitability of the facilities of the other states, the sheriff shall assure himself or herself that it maintains standards of care and discipline not incompatible with those of this state and that all inmates therein are treated equally, regardless of race, religion, color, creed, or national origin.

(b) With the approval of the board of supervisors including agreement as to terms for payments to be made for prisoner maintenance and expenses, the county sheriff may enter into a contract negotiated under subdivision (a).

(c) No prisoner may be transferred to an institution outside of this state under this section unless he or she has executed a written consent to the transfer.

(d) Any person who was sent to another state from a county under the authority of this section shall be released within the territory of the county unless the person, the sheriff of the sending county, and the corresponding official or agency of the other state shall agree upon release in another place. The county shall bear the cost of transporting the person to the place of release.
