Okla. Stat. tit. 63, § 63-685.5: Emergency interim succession to state offices other than

Governor.

All state officers, other than the Governor, subject to such

regulations as the Governor, or other official authorized under the

Constitution and this act to exercise the powers and discharge the

duties of the Office of Governor, may issue, upon approval of this

act, in addition to any deputy, shall designate, by the title of

their office or position, emergency interim successors and specify

their order of succession. The officer shall review and revise, as

necessary, designations made pursuant to this act to ensure their

current status. The officer shall designate a sufficient number of

such emergency interim successors so that there will be not less

than three nor more than seven deputies or emergency interim

successors or any combination thereof, at any time. In the event

that any state officer is unavailable following an emergency or

disaster, and in the event a deputy, if any, is also unavailable,

the said powers of the office shall be exercised and said duties of

the office shall be discharged by the designated emergency interim

successors in the order specified. The authority of an emergency

successor shall cease:

1. When the incumbent of the office, or a deputy or an interim

successor higher in designation becomes available to exercise the

powers and to perform the duties of the office; or

2. When a successor to the office has been duly elected or

appointed and has qualified according to law.
