33Introduction ContinuedMonthly Operator Reports serve several functions
Primary function is it provides a way to track effectiveness of the filtration and disinfection system.
Provides a record of daily operational readings.
A means of reporting to DEC that all regulatory requirements have been met.44Introduction ContinuedDifferent Types of Operator Reports

14Turbidity Reporting RequirementsCombined filter effluent (CFE) turbidity measurements
Taken after the point where all individual filter effluents combine.
Turbidity measurements are taken from grab samples or online turbidimeter recordings taken at four hour intervals.
Recorded on first page of operator report.1515Turbidity Reporting Requirements ContinuedCFE turbidity requirements
95% of all CFE turbidity measurements taken during the month must be less than or equal to:
0.3 NTU for Conventional and Direct filtration plants
1.49 NTU for Alternative, Slow Sand, & Diatomaceous Earth plants
1616Turbidity Reporting Requirements ContinuedMaximum CFE Turbidity limits:
1.49 NTU for Conventional and Direct plants
5 NTU for Alternative, Slow Sand, & Diatomaceous Earth plants
Must notify DEC within 24 hours if maximum CFE limit is exceeded.Document on Page 2 of operator report.1717Elements of an Operator Report Page 1 of Operator Report ContinuedSystem InformationPublic Water System (PWS) NamePWS ID #AddressPhone #Month & Year of reportTurbidityEntry Point ChlorineFilterFluorideOperator Signature Line

20Entry Point Chlorine Reporting RequirementsResidual readings collected daily at entry point to the distribution systemSampling frequency is based on population #s500 or fewer = 1 sample/day
501 1,000 = 2 samples/day
1,001 2,500 = 3 samples/day
2,501 3,300 = 4 samples/day
3,301 or greater and all other systems that monitor continuouslyMust report lowest value each day2121Entry Point Chlorine Reporting Requirements ContinuedEntry point chlorine residuals must be at least 0.2 mg/L at all times.Some systems may have a higher entry point chlorine concentration requirement.To meet contact time requirements.Flow CharacteristicsTurbidity levels
2222Entry Point Chlorine Reporting Requirements ContinuedIf entry point residual drops below 0.2 mg/L
Contact DEC soon as possible - no later than the end of the next business day.
Date and duration below 0.2 mg/L must be recorded on page 2 of the operator report (Entry Point Disinfection Performance Criteria).
DEC will review if treatment technique violation was generated.If chlorine level is raised above 0.2 mg/L within 4 hours, no violation will be assessed.2323Elements of an Operator Report Page 1 of Operator Report ContinuedSystem InformationPublic Water System (PWS) NamePWS ID #AddressPhone #Month & Year of reportTurbidityEntry Point ChlorineFilterFluorideOperator Signature Line

30Fluoride Reporting RequirementsMeasured daily at the entry point to the distribution system.
Entry point fluoride residual must not exceed 2.0 mg/L.
Notify DEC within 24 hours if fluoride residual is equal to or greater than 2.0 mg/L.
3131Fluoride Reporting Requirements ContinuedOn the first day that the fluoride residual is > 2.0 mg/L, a confirmation sample must be collected and sent to a certified laboratory to verify field test results.
Public Notice requirements will be based upon certified laboratory sample results.Circumstances may dictate otherwise.

The owner or operator shall certify by signature that the information and data contained in a report required to be filed under this chapter are true and correct to the best of the owners or operators knowledge.
