Ohio Rev. Code § 3718.07
The director of health shall survey each city and general health district at least once every three years to determine whether there is substantial compliance with the requirements of this chapter pertaining to health districts and the applicable rules adopted by the director under this chapter. Upon determining that there is substantial compliance, the director shall place the district on an approved list. The director may resurvey an approved district if it is determined by the director to be necessary and may remove from the list a district that is found not to be substantially complying with the requirements of this chapter pertaining to health districts and the applicable rules.
If the director determines that a district is not eligible to be placed on the approved list or to continue on the list after a resurvey, the director shall certify that determination to the board of health, and the director shall carry out the duties of the unapproved health district under this chapter and the applicable rules adopted under it within the district or shall contract with an approved health district to conduct those duties until the unapproved district is placed on or returned to the approved list. The director or the contracting district shall have within the unapproved district the authority to exercise powers and perform duties granted to or imposed on the board under this chapter and the applicable rules adopted under it.
Until the unapproved district is placed on or returned to the approved list, the director or the contracting district shall collect all fees payable to the board of health under this chapter and all such fees previously paid to the unapproved district that have not been expended or encumbered. The director shall deposit those fees in the state treasury to the credit of a special fund, which is hereby created, to be used by the director for the purpose of carrying out the duties of the unapproved health district under this chapter and the applicable rules adopted under it. A contracting district shall deposit those fees to the credit of its fund created under section 3718.06 of the Revised Code to be used by the district for the purpose of carrying out the duties of the unapproved district under this chapter and the applicable rules adopted under it. The director or contracting district shall repay to the unapproved district any balance remaining in the applicable fund from all sources when the unapproved district is placed on or returned to the approved list by the director.
If a health district is removed from the approved list under this section and the board of health of the district is regulating small flow on-site sewage treatment systems in the district under section 3718.021 of the Revised Code, the director of environmental protection shall regulate those systems in that district in accordance with division (C) of that section.
