Who We Are
The Compliance Assistance Unit was established by Section 104(g)(1) of the Federal Clean Water Act to help bring wastewater treatment plant (WWTP) facilities into compliance and/or to maintain compliance. Our goal is to improve the water quality of our streams, rivers, and lakes by assisting WWTPs that need help in meeting their National Pollution Discharge Elimination System (NPDES) permit.
The CAU is made up of four team members who cover the entire state of Ohio:

- Team Members: Victor Reverendo, Keith Kroeger, Rick Smith, Jon van Dommelen
What We Do
We provide a free service to smaller communities with wastewater treatment plants of less than 5 MGD. Some of the services we provide include:
- Perform plant performance evaluations to identify cause of compliance issues such as plant design, plant operation, administrative, etc.
- Troubleshoot complex plant problems
- Create innovative and cost effective solutions for improving plant performance
- Onsite training of personnel in process control procedures such as sludge wasting and return rates, mixed liquor concentrations, and dissolved aeration tank oxygen levels
- Help improve sludge handling and disposal procedures
- Teach operators more effective methods of process control
- Investigate concerns over industrial dischargers to the system
- Determine current plant loadings and capacities
- Help formulate and implement a preventive maintenance program
- Help facilitate in Inflow & Infiltration evaluation of sewer system
- Review / evaluate new treatment technologies
- Provide training presentations at wastewater trade seminars and workshops
We travel all over the state of Ohio helping WWTPs identify their performance limiting factors and create cost-effective solutions to bring them back into compliance. We are committed to helping small communities who need assistance in achieving compliance with their NPDES permit requirements.
The Successful Project
The Compliance Assistance Program seldom works without total commitment from community officials. In order to achieve success, we need the same level of commitment from everyone involved: village administrators, superintendents, plant operators, etc.
Many communities have saved money and are operating in compliance at the same time, or at a lower operating cost than prior to participation in the assistance program. In many cases, the cost for compliance is also more economical than paying a penalty for noncompliance. Implementing preventive maintenance programs and identifying energy savings are the methods most used to reach a cost-effective end result.
