Clean Water State Revolving Fund (CWSRF) loan recipients are required to submit a Performance Certification letter to the State Revolving Fund Loan Program (SRF Loan Program) at the end of the one-year start-up period following the facility´s Initiation of Operation. The letter must state that the facility meets or exceeds the performance standards submitted to the SRF Loan Program by the consulting engineer during the Design Phase. If Clean Water State Revolving Funds were used for the construction, upgrade, or expansion of a wastewater treatment facility, the letter must also state that the facility is in full compliance with the facility´s National Pollutant Discharge Elimination System Permit. The SRF Loan Program´s technical staff will conduct an Operation and Maintenance/Performance Certification Inspection and assess the acceptability of the facility´s post-start up performance. A Performance Certification Inspection Report will be prepared by the SRF Loan Program´s technical staff and distributed to the loan recipient and consulting engineer following the inspection. A Corrective Action Report must be submitted to the SRF Loan Program within 30 days of the end of the performance period if the facility´s performance is unacceptable or if the loan recipient is unable to certify the facility´s performance. The Corrective Action Report must describe any problems that preclude the Performance Certification. In addition, a detailed schedule and methods for correcting the problems and certifying the performance of the facility must be provided.
