A review is being performed to determine if basin cleaning is required.Duration of Event The initial O&G sample was collected at 08:50.A follow-up sample was collected at 14:15 which demonstrated that the O&G was within permitted limits.Therefore, the maximum event duration was 5 hours and 25 minutes.Actions Taken to Prevent Recurrence A plant Condition Report (CR)was initiated to document this event and to ensure implementation of necessary corrective action.The Unit 2 WWRB and/or the sumps and oily waste separator that feed the WWRB will be cleaned.An evaluation of the most effective cleaning process is in progress.

SNC Environmental Affairs was notified of the exceedance on February 2.The analysis result was confirmed on February 7, and verbal notification was provided to Georgia EPD on February 7 at 15:16 Eastern.The 5-day written report was waived in lieu of this summary in the quarterly OMR.No indications of an adverse environmental impact were observed in the Savannah River.Follow-up actions included sampling the next available release for this discharge point to ensure that the processing system was functioning properly.This was accomplished on February 17, 2007.The sample was analyzed by the Georgia Power Central Lab and resulted in a suspended solids value of MG/L.Additional actions included having the Georgia Power Central Lab change their protocols to immediately notify the plant when sample results are completed such that more timely follow-up samples can be obtained in the event of an exceedance.

The dechlorination system was not in service at this time.At 08:00 (Eastern)on 4/2/2005, Chemistry contacted the control room to verify that the Unit 1 cooling tower blowdown was still closed.Chemistry was informed that Unit 1 cooling tower blowdown was opened to 15%demand.Immediate sampling indicated that residual levels of chlorine (0.30 mg/I Total Residual Chlorine)were still present in the Unit 1 cooling tower basin, and the dechlorination system was successfully started.It is believed that the chlorine may have been present in uncirculated"pockets," as the system was stagnant at the time of bleach addition.Sampling was also performed at the mixing box (manway)with a result of<0.01 mgll Total Residual Chlorine (TRC)and<0.01 mgll Free Available ChlorIne (FAC), indicating that detectable levels of chlorine were not present In the main plant discharge. No adverse effects were observed in the receiving water body (Savannah River)during this time.Based on the sample data available from 4/1/2005 and 4/212005, no numerical limits for the amount of chlorine present would have been exceeded if a chlorine discharge occurred.However, detectable levels of chlorine can be discharged for no more than 120 minutes per day per unit.Therefore, the time that the Unit 1 cooling tower blowdown was opened is needed in order to determine the potential duration of any chlorine discharge. There was no log entry by Operations for when the blowdown was opened, and no procedures were perlormed by Operations on 4/1/2005 or 4/212005 that specifically required the opening of cooling tower blowdown.TheOperationsdepartment interviewed their personnel, and no one recalled opening the blowdown and no one recalled receiving a request to open blowdown.Each of the Unit 1 circulating water pumps were started duringthistimeframe, but manipulation of cooling tower blowdown is not required to support pump startup or operation. Based on this information, the time that cooling tower blowdown was opened has not been established. The plant procedure addressing operation of the circulating water system and manipulation of cooling tower blowdown requires logging of blowdown manipulation as well as coordination with Chemistry when blowdown adjustments are made.Despite this guidance, there is no record available to indicate when cooling tower blowdown was opened, and no personnel have a recollection of manipulating blowdown.Unless additional information is obtained, this event is not being characterized as a non-compliance as there is not any evidence to support that blowdown was open for more than 120 minutes.Plant procedures are being revised to add controls that will prevent occurrence of a similar event in the future.Southern Nuclear Environmental Affairs (EA)contacted Mr.Mike Creason of the Georgia Environmental Protection Division (EPD)at 14:20 (Central)on 4/4/2005 to provide an initial notification of a potential NPDES non-compliance. After being informed by Operations that the time of opening blowdown could not be established, Mr.Creason was again contacted by EA at 14: 10 (Central)on 4/5/2005.Mr.Creason requested that SNC complete investigation of the incident and provide a summary description with the second quarter NPDES Operational Monitoring Report (OMR), Page 20 of 20 Southern Nuclear Operating Company, Inc.Post Office Box 1295 Birmingham.

Although none of these values exceeded daily maximum of 100 mg/l, the resulting average of 31.3 mg/l slightly exceeded the limit of 30 mg/l.A 24-hour notification was made to Mr.Mike Creason of EPD on October 30, 2003, as required by the Vogtle NPDES permit.Mr.Creason waived the 5-day written report for the average exceedance, and requested that a summary of the condition be included in the next quarterly NPDES report.It is believed that a'bloom'of algae in the Unit 2 WWRB, generated by warm sunny weather combined with the organic nutrients present in the bottom of the basin, contributed to a temporary elevation of TSS values.As demonstrated by sampling data from November 2003 and December 2003, the Unit 2 WWRB is now in compliance with permit limitations for TSS.This report is provided as an attachment to the Fourth Quarter Operational Monitoring Report, per discussion with Mr.Mike Creason on October 30, 2003.

Discharge hom the basin was halted after obtaining analysis results irom the sample, and the basin\vas placed in a recirculation mode.On July 13, 2003, the basin was sampled during a static period (no discharge occurring) with an 0&0 result of2.54 mg/L.Based on this infol111ation, the basin was cleared to resume discharge. A message was left with Mr.Mike Creason of EPD on Sunday, July 13, 2003, providing thehour verbal notification as required by the Vogtle NPDES permit.A follow-up discussion was held with Mr.Creason on Monday, July 14, 2003, and the 5-day written reportwaswaived. It is believed that repair activities on the Unit 2 WWRB contributed to a disturbance of the sludge layer in the basin which resulted in the temporary elevation ofTSS and O&G values.The Unit 2 WWRB was drained to a very low level to facilitate inspection and maintenance on one of the discharge pumps.While the basin was drained, it is believed that the bottom sludge layer was destabilized by the activation of algae and by adsorption of surface oil.As the WWRB was refilled following the maintcmmcc activities, the oil was slowly released whieh led to the higher than expected O&G values, Additionally, algae may also have been released to the water fi'OlTI the sludge layer which resulted in the elevated TSS values.Draining of the WWRB for maintenance is a vcry infrequent task.Upon averaging the sampling data at the end of the month, SNC contioned that the Daily Average limit for TSS'would be exceeded for the Unit 2 WWRB, due to the event described above.Mr.Creason was contacted on August 1, 2003, to provide 24-hour verbal notitIcation of the average exceedance. Mr.Creason also waived the 5-day written report for the average exceedance. As demonstrated by sampling data from August 2003 and September 2003, the Unit 2 WWRB is now in compliance with pennit limitations.

Samples were taken during the bypass to confinn compliance with NPDES pennit requirements.

The shutdown, resulting cleanup operation, and subsequent dual unit startup produced influent flow that exceeded the capacity of the WWRBs.Under these unusual conditions, the basins were filling up faster than the installed WWRB pumps could remove the water.The amount of water entering the WWRBs could not be reduced without jeopardizing the integrity of plant equipment. A bypass under the provisions of Part II.A.5 of the NPDES permit was initiated to ensure the excess water could be appropriately managed to protect critical plant equipment. On November 25, 2002, as plans were being developed to institute a bypass (pumping directly from the WWRBs to a yard drain), the basins reached capacity and the overflow entered a yard drain.This overflow event required immediate initiation of the unanticipated bypass.VEGP obtained concurrence from Mr.Michael Creason of the EPD Industrial Branch for the initiation of the bypass.The temporary pumps were installed later to increase the capacity for water removal and provide a more controlled means of managing the bypass.The overflow duration was limited to only a few hours, and very little flow was involved.Samples were taken confirming compliance with NPDES Permit'requirements. Part II.A.5 of the NPDES Permit specifically allows for a bypass when permit limits will not be exceeded.The bypass initially consisted of an overflow, and was subsequently enhanced by placing a portable pump at the basins.The path of the bypass was the transfer of water from the WWRBs to a nearby yard drain.The pump suction was placed several feet below the waterline so that any floating material would not be discharged to a yard drain.On the day that the pump was utilized to prevent overflow of the basin, sampling was performed for pH, Total Suspended Solids (TSS), and Oil and Grease (O&G).In accordance with permit provisions, Mr.Michael Creason was informed of the bypass condition within 24 hours of initiation. The results of the bypass sampling are provided in the following table.The WWRB permit limits for TSS and O&G were not exceeded, and the pH was between 6.0 and 9.0 S.U.Bypass Sampling Information Date Duration pH (SU)TSS (mg/l)O&G (mg/l)11125/2002 <12 hours Unit 1-8.63 Unit1-1.9 Unit 1-10.5 (Overflow)(very little flow)Unit 2-8.76 Unit 2-1.5 Unit2-6.2 11126/2002 142 minutes 8.45 1.6<1.0 (Pump)(Unit 1 Only)

.., I..The equipment for the bypass was put in place on November 26, 2002, and was available for use until December 13, 2002, when the bypass was terminated.

In accordance with permit condition II.A.S, the required 24 hour verbal notification was provided to theEnvironmentalProtection Division (Mr.Mike Creason)on November 25, 2002.Mr.Creason confirmed that the required 5-day written report would be provided after termination of the bypass conditions. Duration of Bypass The bypass was in effect for 18 days, with flow only occurring on two of those days.Approximately 142,000 gallons of water were sent to the yard drain.On December 13, 2002, the basins were returned to a normal configuration utilizing Outfalls 004 and 005.Steps to Prevent Recurrence The simultaneous shutdown of both operating units at Plant Vogtledueto chemical intrusion is an extremely unusual event and is not anticipated to recur.As SUCh, no specific actions to prevent recurrence are deemed necessary. Lessons learned from the experience of extended high hydraulic loading of the WWRBs will be utilized, as appropriate, to enhance plant response to such events in the future. ,*.\,-Vogtle Electric Generating Plant NPDES Permit No.GA0026786 I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.
