Ohio Rev. Code § 3701.347
Notwithstanding division (E) of section 6111.42 of the Revised Code, rules adopted under such division and in effect on December 14, 1978, shall continue in effect until repealed by the environmental protection agency or superseded by rules adopted by the director of health as hereinafter provided, as fully as if such section had not been amended by Amended Substitute Senate Bill No. 445 of the 112th general assembly on such date. Insofar as these rules affect wells for the provision of water for human consumption not used or for use by a public water system, they shall remain in effect notwithstanding repeal by the environmental protection agency until the director adopts rules superseding them which prescribe uniform standards and procedures for the design, construction, inspection, installation, development, maintenance, and abandonment of private water systems, to protect the health of the persons served by such water systems and to establish fees at a level calculated to pay the cost of administering and enforcing such rules by the director or by boards of health of city and general health districts approved by the director of health. For purposes of this section "public water system" has the meaning ascribed to it in section 6109.01 of the Revised Code.
