Ohio State is in the process of revising websites and program materials to accurately reflect compliance with the law. While this work occurs, language referencing protected class status or other activities prohibited by Ohio Senate Bill 1 may still appear in some places. However, all programs and activities are being administered in compliance with federal and state law.

Utility Marking

Request Utility Marking

 All utilities - both university and public - must be properly located and marked before any digging.

Contact the Ohio Utility Protection Service (800-362-2764) for utility marking, both university-owned and public utilities.  OUPS will forward your request to Ohio State personnel for handling, and they will be in touch with you direct.
