From the Ohio Environmental Protection Agency Division of Materials and Waste Management:

In February of 2013, the Division of Materials and Waste Management (DMWM) changed the requirements for submitting the Hazardous Waste Report from annual to biennial. Generator and TSD data has since only been collected for odd numbered years and is due by March 1st for the following year. Please do not submit reports for 2014 as data for even numbered years is no longer required. If you need to submit a report prior to 2016 for the 2015 calendar year, please contact us.

However, if you normally submit other reports or data with your annual report that are not part of that report (e.g., the ground water monitoring annual report required by OAC 3745-65-94) please be aware that the frequency of these reports or data has not changed.

If you have any questions about this, or any other reporting issues, please contact Thomas Babb at 614-914-2527 or through email at thomas.babb@epa.ohio.gov
