40 CFR 141.720(d)(1) UVDGM 3.5 & 5.10 Dose Calculation: Will the relative UV intensity term (S/So) in the calculated dose UVDGM Table B.11 equation be based on the lowest measured lamp intensity in the reactor? Provide an example calculation of UV dose at worst-case conditions of UVT, flow, and UV intensity (e.g. design fouling/aging factor). Please include all relevant validation factor parameters. What will be provided for calibration verification of online UVT Calibration: UVDGM 6.4.1.2 AWWA F110-12 UVT analyzers? Sec. 4.5.7 P&ID: Provide process and instrumentation diagrams, PLC logic loop descriptions, UVDGM 4.3 and a process control narrative. Please include alarm descriptions and triggers. O&M Manual: Will the O&M manual include UV system operational curves to allow the operator to visually verify the delivered dose given key input parameters (e.g. flow, UV intensity, UVT)? Manual Override: Is there a manual override of dose monitoring equation inputs UVDGM 6.1.1 & 6.4.1.2 to temporarily keep the UV system running in case a sensor malfunctions? Are emergency operations addressed in the O&M manual? Access to PLC Equations: Will operators or field commissioning staff have access AWWA F110-12 Sec. 4.6.2 to the programmed dose monitoring equation parameters? DEC may request access during inspection to verify the programmed equation is the same as the validated one. Additional submittal requirements for systems the set-point dose monitoring approach Reference Conditions: Please summarize the set-point conditions (e.g. flow, UV 3.5.2.1 & 5.6.1 intensity, lamp status values). What will be the validated dose at set-point and its associated target pathogen inactivation credit? UV Transmittance: Will UV transmittance be measured (note: not typically required for set-point based systems)? If so, how?
