Reactor Total Flow Through (MG) of Off-Specification Events Off-Specification Data Total Off-Specification Volume (MG) Total Volume for Plant Compliance Certification Total Off-Specification Volume for Plant Total Volume of Off-Specification Water Produced (MG). Total Volume of Water Produced (MG). Total Off-Specification Water Produced (% of Volume of Water Produced) [A]/[B]*00. Facility Meets Off-Specification Requirement (< 5% of Volume on a Monthly Basis). Of the sensors, have been checked for calibration and were within the acceptable range of tolerance. The following Reactors had a Sensor Correction Factor Reactor Sensor Correction Factor I certify under penalty of law that I have personally examined and am familiar with the data submitted in this MOR; that the data in this report is true, accurate and complete; and I am aware that falsification thereof could result in the imposition of fines and penalties Page

2 Daily Operational Data (Calculated Dose Approach) Validated Dose = Calculated Dose VF x CF Calculated Dose = Dose calculated by validated PLC algorithm VF = Validation Factor CF = UV intensity sensor Correction Factor. The CF is only applied if sensors do not meet recommended criteria (NOTE a CF will not be needed in most cases) PWS Name:. UV Reactor :. Maximum Validated Flow Rate:. PWSID:. Minimum Validated UVT:. Target Log Inactivation:. Target Pathogen:. Reporting Period: Dose Required (D req d ):. Day Operational Data Dose Requirements Data at Daily Minimum Validated Dose Run Time (hrs) Total Production (MG) Dreq d (mj/cm ) UV intensity Sensor Correction Factor Calculated Dose (mj/cm ) [ C ] Validation Factor (VF) Daily Minimum Validated Dose ([C]/[VF]/[B]) (mj/cm ) [ D ] Flow Rate (MGD) UVT ( % ) UV Dose Adequacy Determination Validated Dose > Dreq d ([D] > [A]) Total Off-Specification Total Off-Specification Volume 5 (MG) Page

3 Min Max Total D req d is the dose required for the target log inactivation without a VF or Sensor CF applied and can be found in the Ultra-Violet Disinfection Guidance Manual, Table.. Sensor CF will be if no CF is used. Calculated dose is calculated using the dose algorithm in the PLC. The Validated Dose is the dose based on the calculated dose normalized on the Validation Factor and Correction Factor. 5 Off-specification worksheet (Figure 6.5) should be used to calculate any daily off-specification volume. If UVT, flowrate, and/or Validated Dose off-specification occur simultaneously, the off-specification time should only be counted once. Page

4 PWS Name:. Off-Specification Calculation Worksheet PWSID:. Reporting Period:. (Note This sheet should only be used when an off-specification event occurs) Date Reactor Process Train Off-Specification Event Description Flow Rate (gpm) [A] Time (minutes) Off-Specification Volume (gallons) ([A]*[B]) Total Off-Specification Flow for the Day A worksheet must be completed for each reactor with an off-specification event. All off-specification events in a day can be included in one row. Off-specification events on different days must be reported on separate rows. This worksheet assumes the flowrate was constant during the off-specification event. Off-specification event volume can also be obtained from a flow totalizer. Off-specification event can be caused by UVT, flowrate, intensity, or validated dose being out of the validated range. The total off-specification flow should be transferred to Figure 6. or 6. if any off-specification events occurred. Page

5 Calibration Ratio: Sensor Correction Factor: UV Sensor CF Calibration Worksheet S Duty S Ref S Duty - 0. S Ref where S is the measured intensity PWS Name:. Reporting Period:. PWSID:. CF used (if applicable):. Date Reactor Duty Sensor UV Sensor Operating Time (hrs) Reference Sensor Serial Duty UV Sensor Reading Reference UV Sensor Reading Calibration Ratio ([A]/[B]) Calibration Ratio. Sensor Correction Factor Used If CF is used, Calibration Ratio 0. CF Certification: of UV sensor calibrated. of UV sensors out of calibration. of UV sensor(s) sent to manufacturer to be recalibrated as documented below. UV intensity sensors sent to manufacturer for calibration (Add additional rows as necessary): Sensor Serial Unit No. Date Sent Date Put Back in Service Page 5

6 Correction Factor = S Duty S Ref - 0. UV Sensor CF Calibration Worksheet Where: S Duty is the duty UV sensor reading S Ref is the duty UV sensor reading PWS Name:. Reporting Period:. PWSID:. CF used (if applicable):. Optional Sensor Correction Factor Worksheet: Date Reactor Duty Sensor UV Sensor Operating Time (hrs) Reference Sensor Serial Duty UV Sensor Reading Refernce UV Sensor Reading Sensor Correction Factor (([A]/[B])-0.) Only failed sensors need to be input. UV Sensor CF should be based on the calibration ratios for the failed sensors and should use the maximum ratio. The CF is reactor specific. If three duty UV sensor and reference UV sensor readings are taken, the mean of the reading can be used. Selected UV Sensor CF Page 6
