On March 31, 2010, the Governor of Ohio signed a major revision of the state's Oil and Gas Code. Initially proposed by the state's Department of Natural Resources, the revised code was designed, among other things, to accommodate and provide the general legislative framework necessary for the geologic storage of CO2 in the state.

The law became effective on June 30, 2010. It does not address aggregation of storage rights, long-term liability or pore space ownership, although pore space ownership is arguable well-established under Ohio law. Authority is provided in the legislation for rule-making, which is expected to begin in 2010.
