Ohio Rev. Code Ann. § 4906.10
(A) The power siting board shall render a decision upon the record either granting or denying the application as filed, or granting it upon such terms, conditions, or modifications of the construction, operation, or maintenance of the major utility facility as the board considers appropriate.
