Ohio EPA Certification

Ohio EPA Certification Options Comparison Tool

WPI is an approved exam provider for Ohio EPA. To receive your Ohio EPA certification, there are two options listed below.


Ohio EPA Certification

Description
An option for operators seeking Ohio EPA Certification. This path is only for the approved exam and does not result in WPI/C2EP certification.

Exam/Certification Programs Offered

  • Ohio EPA Wastewater Collection Class I
  • Ohio EPA Wastewater Collection Class II
  • Ohio EPA Wastewater Treatment Class A
  • Ohio EPA Wastewater Treatment Class I
  • Ohio EPA Wastewater Treatment Class II
  • Ohio EPA Wastewater Treatment Class III
  • Ohio EPA Water Distribution Class I
  • Ohio EPA Water Distribution Class II
  • Ohio EPA Water Supply Class A
  • Ohio EPA Water Supply Class I
  • Ohio EPA Water Supply Class II
  • Ohio EPA Water Supply Class III

Process
Visit the Ohio EPA Certified Operators website to review the eligibility criteria to sit for the exam. If you meet the eligibility criteria, go to PSI’s website to start registering for your examination. During registration, you will be required to attest to your eligibility and intent to apply for Ohio EPA certification. Once you have passed your exam, submit your examination results, Ohio EPA application for certification, and applicable fees to Ohio EPA.


C2EP/Ohio Certification

Description
An option for operators seeking both Ohio EPA and WPI/C2EP certification. WPI/C2EP certification further enhances the recognition and public visibility of those earning its certifications by designating them as “Professional Operators,” a title that highlights the considerable knowledge, experience, and skills required to meet WPI/C2EP standards. Though this is a voluntary opportunity, earning this designation signifies your commitment to the profession and expertise in the industry, thereby boosting not only your professional stature as an operator, but the credibility and public reputation of the organizations you represent. In certain municipalities and union contracts operators may receive additional compensation for acquiring and maintaining multiple certificates. Obtaining a professional operator (PO) designation and WPI certification may qualify an individual for additional compensation. Please check with your supervisor and/or union representative to see if you are eligible for additional compensation.

  • C2EP Collection Class I
  • C2EP Collection Class II (Ohio EPA Wastewater Collection Class I)

Process
Assemble the appropriate supporting documentation required for your application. Complete the C2EP Certification Application and submit it to C2EP with the required fee and supporting documentation. Be sure to indicate Ohio EPA on your Third-Party Authorization Form. C2EP will review your application within 30 days of receipt; you will be notified if any additional information is required to approve your application. Once your application is approved, you will receive an exam scheduling notice from PSI.  Follow the directions on this notice to schedule your exam. Once you have satisfied all eligibility requirements and passed the appropriate exam, you will receive a WPI/C2EP Certification. Submit your examination results, Ohio EPA application for certification, and applicable fees to Ohio EPA.
