Ohio Rev. Code § 3511.15: Emergency absentee voting procedures.

If an international, national, state, or local emergency or other situation arises that makes substantial compliance with the "Uniformed and Overseas Citizens Absentee Voting Act," 42 U.S.C. 1973ff, et seq., as amended, impossible or impracticable, as confirmed by the existence of armed conflict involving United States armed forces or the mobilization of those forces, including Ohio national guard and reserve component members of this state, or by the occurrence of a natural disaster or the existence of a state of emergency, civil unrest, war, or other exigency in a foreign country, or by an official declaration by the governor that a state of emergency exists, the governor directly, or by delegation to the secretary of state, may prescribe, by emergency order or rule, a special procedure or requirement as may be necessary to facilitate absent voting by those absent uniformed services voters or overseas voters directly affected who are eligible to vote in this state. The secretary of state shall take reasonable steps to provide absent uniformed services or overseas voters with timely notice of any special procedure or requirement prescribed under this section.
