Ohio Rev. Code § 505.12
The board of township trustees may secure, maintain, and provide for solid waste facilities as defined in section 3734.01 of the Revised Code if in its opinion the facilities are necessary, and for that purpose the board may purchase, rent, lease, or otherwise acquire land suitable for those facilities. The boards of township trustees of any two or more townships or the legislative authorities of any two or more political subdivisions, or any combination thereof, may through joint action unite in the joint purchase, rental, maintenance, use, and operation of solid waste facilities and prorate the expense on any terms that may be mutually agreed upon. The selection of any site shall have the approval of the board of health of the health district in which the facility will be located.
When so required by rules adopted under division (G)(2) of section 343.01 of the Revised Code, the board of township trustees, before constructing, enlarging, or modifying a solid waste facility, shall obtain approval for the facility from the board of county commissioners of the county or board of directors of the joint solid waste management district, or board of trustees of a regional solid waste management authority if such has been formed under section 343.011 of the Revised Code, having jurisdiction for compliance with the initial or amended solid waste management plan of the district approved under section 3734.521, 3734.55, or 3734.56 of the Revised Code.
