Dear Mr. Gomes:

'la accordance with Part 111, paragraph 12.A. of OEFA Permit No. 31500016*CD, l this. notification is hereby submitted for a reportable event which occurred on October 25, 1989. '

' iT65T Perry Discherse Tunnel Free avail 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months (2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months 10/25/89 Event Descristion The Perry Plant Discharge Tunnel released free available chlorine at as appreminate concentraties of 0.2 ag/l between the heers of 10:10 AM and 9:35 l PM (approsiaately 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months of actual discharge oecarred daring this period) es L October 25. 1949. The event occurred because the Service Water Chlorinaties

[ System was inadvertently placed in a contineses addition mode without the l

P

. Deehlorisation System operating. The Service Water Chierisation Systen sormally injects sodies hypochlorite for a 1/2 hour period twice per day, '

' daring which time the Dochlorination System is automatically initiated.

The Service Water Chlorinaties Systes is aeraall) controlled by 2 timers which

. set the f requency of sodium hypochlorite addition (overy 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months ) and the ,

duration of each addition (1/2 hour). During a chlorination period, which started at 10:10 AN en October 25, 1949, the servica Water Weir Structare f(apetream of the Dochlorination Systes injection potat) was sampled at 10:30 AM and had a free available eklerine concentration of 0.45 as/1. At 10:35 AM it was discovered that the Dechlorination System had failed' to start per its autoastic function, des to a power outage. At 10:40 AM the Plant Discharge Ttammel was saepted and had a froe available chlorine concentration of 0.20 as/1. _ Af ter the sample was taken of the Plant Discharge Tuanel, the

. Dochlorisation System was massally started. At 11:00 AM the Plant Discharge i

! Ttssnel was. re-sampled and me free available eklorine was detected. After the chlorisation cycle was confirmed to have been completed, the dochlorisation pump was secured. At 11:15 AM the technician was directed to adjust the E &____________--------~ - -- -

' Service Water Chlorination timers to prevent further chlorination cycles until the cause of the dochlorisation probles could be determined. However, the *-

timers were mistakenly placed'in a position which caused continuous chlorination. At 6:00 PM the sodium hypochlorite storage taak was found empty and was refilled. Later evaluatione determined that the tank was empty at approminately. 3:40 pH, based on sodium hypochlorite addition rate. At 9:30 pH the probles was discovered, and taasdiate actions were taken to mammally start t the Dechlorisation system (which was still in a power outage). The tiests A were also reset to their moraal position so that the chlorination cycle would be completed at 10:00 PM. At 9:35 the Plant Discharge Tunnel was stapled and ne f ree available chlorine was detseted. At 10:00 pH the Service Water Weir Structure was sampled and had a free available chlorine concentrattom of 0.40 mg/1.

The free available chloriae release through the plant discharge tunnel was stopped at 9:35 pH when the Dechterination System was confirmed operational.

The release duration was approximately 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months based on the total time staus ,

the periods when the Dechterisation System was in operation and the sodium hypochlorite storage tank was empty. Sample results for free available ehlorine of the Discharge Tuamel (0.2 ag/l at 10:40 AM) and the Service Water Weir Structure (0.45 mg/l at 10:30 AM and 0.40 mg/l at 10:00 PM) indicate that the f ree available chlorine daily concentration limit of 0.3 ag/l was not esteeded during the event.

The cause of this incident was the improper shutdown of the Service Water Chlorination Systoa. A teehaitian used the wrong procedure. The procedure that was used addressed a study of chlorination doses needed to control sobra massel infestation. It did not provide direction for shutting down the systes. The techaittaa had not received training concerning system shutdowa

and did not know another procedure existed for this task. The power outage

.ubich prevented the start of the Dochlorination Sysi;t a was also a contribating taster. .

' To prevent recurrence all applicable technicians and supervisors will receive ,

On-The-Job and Classroom training to further espand systen knowledge and ensure the correct operation, using the proper procedures, of all chlorination and Dechlorisation Systees. la addition, applicable plaat procedures will be reviewed and revised to ensare that power outages that will affect the operation of the Chlorination or Dochlorisation systems are recognised and aeted upon to preerst any fatore recurrence of this event.

Please contact me if you have any questions.

On 10/25/89 at 1010 a annual 1/2 hour chlorination cycle of the Service Vater -

(SV)' System was initiated per Chemistry Instruction ON11A CRI-39 Non-Program sample Analysis and Activites for SV Chlorination. At approximately 1040 a ,

ebenistry technician noticed that the sodium sulfite feedpump (dechlorination '

chemical) had not started. The technician lamediately sampled the plaat discharge tunnel and analysed it for Free Available chlorine (FAC). The result, 0.20 ppe was below the NPDES limit of <0.50 ppe. The technician then annually started the dochlorination pump and resampled the Plant Discharge Tunnel at 1100. The result was 0.0 ppe FAC. Af ter the chlorination cycle was complete .the dochlorination pump va.s secured. The technician then notified chemistry supervision of the failure of the dechlorination pump to start. At 1115, per direction of a chemistry supervisor, the technician adjusted the chlorination timers to prevent further chlorination cycles until the cause of the dochlorination probles could 1-be determined; however the timers were mistakenly placed in a position which l- caused continuous chlorination. Chemistry supervision investigated the pump start failure and discovered the power outage. At 1800 the sodium hypochlorite storage -

tank was found empty by operations and refilled to a level of 60%. Based on sodium hypochlorite addition rate the tank was empty at approximately 1540. At 2130 a chemistry technician reset the SV Chlorination System timers to their rN rmal position which ended the chlorination cycle at 2200 (Putting the timers in .

their normal positions stopped the Ma0CL addition 1/2 hour later). The chemistry technicias was aware of the power outage and at 2133 the Dochlorination System was manually started. At 2135 the Plant Discharge Tunnel was sampled and no FAC was detected. The Chemistry shif t Supervisor notified the Control Room of the }

situation. and this condition report was generated. The EPA and NRC vere properly I notified. The SV Chlorination System was shutdown by Operations a few hours later I -

to prevent any further chlorination cycles. .

l !

The FAC release through the plant discharge tur.nel was stopped at 2135 when the -

Dechlorination System was confirmed operational. The release duration was I approximately 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months based on the total time minus the periods when the Dochlorination System was in operation and when the sodium hypochlorite storage tank was empty. The 9 hour1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months FAC release on 10/25/89 violated the NPDg8 permit which allows only 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months of FAC (that is (0.5 ppe) discharge per day. Sample ,

results for free available chlorine of the Discharge Tunnel (0.2 ppe at 1040) and the Service Water Voir Structure (0.45 ppa at 1030 and 0.40 ppe at 2200) indicate .

that the FAC concentration limit of <0.5 ppe was not exceeded during the event. -

CAUSB:

1 l The root cause of the event was inadequate knowledge of system operation and associated training (A4 Cause code). The cause of this incident was the improper shutdown of the SV Chlorination Systes. A contract chesistry technician used the wrong procedure. The procedure that was used.
