SUBJECT:
Catawba Nuclear Station Conventional Wastewater Treatment System (WC)
Noncompflance Notification File: CN-702.26
Dear Sir:
In accordance with Part II.B.2 of the Catawba Nuclear Station NPDES permit
-(SC0004278) as a follow-up to the telephone notification to the Catawba District Office, Fort Lawn, S.C. , this is to notify you of a noncompliance incident at the Catawba Nuclear Station. Information related to the incident is as follows:
Discharge The discharge was the Conventional Wastewater Treatment System (WC, discharge 002) into Lake Wylie.
Cause of Noncompliance The discharge contained a hydrazine concentration of 8.0 mg/1. Based on the flowrate and duration, the calculated quantity of hydrazine discharged was approximately 68 pounds.
Date and time The WC system discharge began at 2140 hours0.0248 days <br />0.594 hours <br />0.00354 weeks <br />8.1427e-4 months <br /> on February 29, 1988. The discharge was terminated at 0920 hours0.0106 days <br />0.256 hours <br />0.00152 weeks <br />3.5006e-4 months <br /> on March 1,1988 when hydrazine was discovered within the system. j Duration The duration was approximately 11 hours1.273148e-4 days <br />0.00306 hours <br />1.818783e-5 weeks <br />4.1855e-6 months <br /> and 40 minutes.

once hydrazine was discovered in the B-pond of the WC System, the discharge

treatment.
They were being recirculated for DHEC had given approval to discharge hydrazine up to a concentration of 0.43 mg/1. The B-pond was sampled and analyzed on N February 29, 1988 and determined to be within specification for release for the normal NPDES parameters as well as hydrazine. In order to prevent all 2 ponds from filling and thereby leaving no capacity to receive wastewater
- from the station, it was decided to discharge the B-pond as it received
% wastewater f rom the station. In the meantime, a vessel thought to contain only condensate was drained to the WC system. The vessel, however, g contained hydrazine.
On March 1, 1988 a cocposite sample of B-por d was analyzed for hydrazine.
{ The hydrazine concentration was 8.0 mg/1. Immediately, a discharge sample m
was collected and the discharge was stopped at 0920 hrs. The results of
= the analysis of the discharge sample was also 8.0 mg/1. Between 1000 and P
1115, samples were taken in Lake Wylie approximately 2 feet from the WC g discharge and downstream at the radiological sampling point. The results
= of the analyses were 0.108 mg/l and no detectable hydrazine, respectively.
W In the discharge cove, approximately six small bream and several dozen
[ threadfin shad were observed dead. A more complete investigation by Duke r
t Power Biologists revealed that threadfin shad were observed dead in other
- areas of the lake unaffected by the discharge. This would indicate that their deaths were due to natural conditions such as low water temperatures.
5 All appropriate State, County, and Federal officials were notified of this E event. Should you desire additional information or have any questions please contact R.T. Simril [(704) 373-2310] or M.C. Griggs [(704) f 373-7080].
