Dear Mr. Hedges:
In accordance with Part II.A.2. of the above-referenced NPDES permit, attached is a report of the circumstances of the chlorine exceedance which was reported to Mr. Michael 8.

Plant E. I. Hatch NPDES Per.it No. GA 0004120 Descriotion of Event A weekly sample from the Unit 1 final discharge mixing chamber (OSN 01) taken at 0905 hours0.0105 days <br />0.251 hours <br />0.0015 weeks <br />3.443525e-4 months <br /> on 12/30/91 indicated that chlorinated water was being discharged t.o the Altamaha River with a total residual chirrine (TRC) concentration of 1.4 parts per million (ppm) and a free available chlorine concentration (FAC) of 1.2 ppm.
No specific chlorine limits for OSH 01 are specified in the NPDES Permit.
However, the permit does require an increased sampling frequency at OSN 01 of once per 15 minutes during pericds of chlorinated water discharge.
A measurable chlorine concentration at OSN 01 was not expected and, therefore, this increased sampling frequency was not being performed prior to the analysis of the weekly sampic. An increased sampling frequency was initiated upon discovery of the measurable chlorine concentration.
Cause of Event The direct .ause of the event was an internal failure of the valve which isolates the chlorine addition system from the Unit I service water system intake. The chlorine addition system serves the service water intakes for both UC t 1 and Unit 2. Due to the valve failure, the Unit I service i
water system was receiving an unintentional chlorine treatment during a planned chlorine addition to the Unit 2 service water system. The Unit I service water system was aligned at the time t- discharge directly to OSN 01.
Period of Evnt The discharge of chlorinated water began at 0730 when the Unit I service water system was first aligned to discharge directly to OSN 01. At 1000, following identification of the failed valve, the chlorine addition to the service water systems was terminated. TRC and FAC concentrations at OSN 01 both decreased to <0.1 ppm by 1040. The time of chlorine discharge through OSN 01 was approximately 190 minutes.
Actions Taken to Prtyent Recurrence e
- 1. The failed plant service water chlorine addition 'nive has been replaced.
- 2. The corresponding valve for Unit 2 will be inspected for similar conditions as was found on Ur.it I within the next 30 days.
E-
- 3. As an additional measure to preclude an unplanned discharge of.
chlorine:from-the site due to an ondetected valve-failure, chlorine will normally be added to a plant service water system onLg;when the service water systems of bot 1 units are aligned to discharge to the circulating water system of the respective unit. At times when chlorination of the plant service water system is required and the above alignment is not possible (e.g., with either unit's plant service water system being diverted directly to the final discharge mixing chataber) then sampling will be performed at the final-discharge mixing chamber of both units to verify that the chlorine addition is occurring only on the desired unit's plant service water system.
- 4. Chlorination of- the plant service water systems for both units has been suspended until-the necessary operating procedures have been.
modified as described above.
