As a precautionary response to COVID-19, Ohio EPA is currently operating with most staff working remotely. If you are working with our staff on a current project and you know the name of the employee you are working with, email them at or call them directly. The Agency website has contact information for every district, division, and office. To report a spill or environmental emergency, contact the spill hotline (800) 282-9378 or (614) 224-0946. This number should only be used for emergencies. For all other calls, please contact Ohio EPA’s main phone line at (614) 644-3020 or the main line for the division or office you are trying to reach.

After March 23, our district offices and Central Office will be temporarily closed and will have increasingly limited ability to receive deliveries, plans, etc. All entities are encouraged to submit plans, permit applications, etc., electronically where there are existing avenues to do so, such as the eBusiness Center (eBiz). Please refer to the list of available services on the main eBiz webpage. We encourage you to make use of all that apply, even if you have not used eBiz in the past. Plans under 25 MB can be emailed. For large plans over 25 MB, entities should work with the reviewer/division to upload via LiquidFiles. Directions for submitting docs via LiquidFiles is available on YouTube. We apologize for the inconvenience and thank you in advance for your understanding. If you wish to send hard copies of documents to any of Ohio EPA’s district offices, the best method to ensure we receive these documents is to send them via U.S. Mail. Since all offices are closed, deliveries outside of U.S. Mail (FedEx, UPS) will likely be returned because the offices are closed and deliveries cannot be made.


Ohio EPA Announces New Water and Wastewater Operator Certification Exam Options

New options to make it more convenient for Ohio water and wastewater operators to gain certification have become available through a third party exam provider recently approved by Ohio EPA.

Association of Boards of Certification (ABC), an approved exam provider, offers computerized operator certification exams five to six days per week at approximately 200 locations across the United States. Ohio EPA operator certification exams available through this program include:

  • Water Supply, Classes A, I, II, and III
  • Water Distribution, Classes I and II
  • Wastewater Treatment, Classes A, I, II, and III
  • Wastewater Collection, Classes I and II

These online exams are available more often and in more locations than traditional pencil and paper testing. The exams will be offered in Cleveland, Cincinnati, Columbus, Dayton and Toledo.

To apply for an exam, applicants must have a high school diploma or equivalent, and the amount of operating experience required for each classification level. See for more details. Once a prospective operator has passed an ABC-issued exam and met experience requirements, they can submit an application to Ohio EPA with a non-refundable $45 application fee. Upon review of the application to ensure criteria have been met, Ohio EPA will issue the appropriate certification to the operator.

Any questions regarding eligibility should be sent to Ohio EPA at or 1-866-411-OPCT (6728).

Ohio EPA will continue to provide traditional exams in Columbus in the spring and fall each year. For more information about Ohio EPA operator certification requirements and eligibility, please visit


The Ohio Environmental Protection Agency was created in 1972 to consolidate efforts to protect and improve air quality, water quality and waste management in Ohio. Since then, air pollutants dropped by as much as 90 percent; large rivers meeting standards improved from 21 percent to 89 percent; and hundreds of polluting, open dumps were replaced with engineered landfills and an increased emphasis on waste reduction and recycling.
