Ohio Revised Code Title XV. Conservation of Natural Resources § 1509.12

(B) When the chief finds that a well should be plugged, the chief shall issue an order to the person that owns the well or that is responsible for the well to plug the well and shall specify in the order a reasonable time within which to comply. No person shall fail or refuse to plug a well within the time specified in the order. Each day on which such a well remains unplugged thereafter constitutes a separate offense.

Where the plugging method prescribed by rules adopted pursuant to section 1509.15 of the Revised Code cannot be applied or if applied would be ineffective in carrying out the protection that the law is meant to give, the chief may designate a different method of plugging. The abandonment report shall show the manner in which the well was plugged.

(C) In case of oil or gas wells abandoned prior to September 1, 1978, the board of county commissioners of the county in which the wells are located may submit to the electors of the county the question of establishing a special fund, by general levy, by general bond issue, or out of current funds, which shall be approved by a majority of the electors voting upon that question for the purpose of plugging the wells. The fund shall be administered by the board and the plugging of oil and gas wells shall be under the supervision of the chief, and the board shall let contracts for that purpose, provided that the fund shall not be used for the purpose of plugging oil and gas wells that were abandoned subsequent to September 1, 1978.
