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 www.abccert.org/Ohio_EPA/certification_process.asp 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 opcert@epa.ohio.gov 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 www.epa.ohio.gov/ddagw/opcert.aspx.


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.
