For now, I've copied down a portion of the Case Notes and OAG for RC §517.21 of the Ohio Revised Code found under "Townships" on page 174 in the book:
Case Notes and OAG
#2. (1953) A cemetery may be considered as abandoned under RC §517.21 when all or practically all of the bodies have been removed therefrom and no bodies have been buried therein for a great many years, and the cemetery has been so long neglected as entirely to lose its identity as such, and is no longer known, recognized and respected by the public as a cemetery: 1953 OAG No. 2978.***************************************

Link below to Ohio townships (listed by county name) which have websites. This is found on the website of the Ohio Township Association.
Contacting township clerks and trustees goes hand-in-hand with filing complaints and asking for help (try asking for help first!) regarding issues of concern with inactive/abandoned or even active cemeteries that are wholly or partially within one or more townships.
