St. Lucie Unit 1 Docket No. 50-335 Florida Wastewater Permit Deviation On Friday, September 12, 1997, samples were taken for CBOD, at the influent and effluent of the St. Lucie Unit 1 Sewage Treatment Plant (STP).
These samples were analyzed offsite and due to sample processing time, it was not determined until later in the month that the resulting CBOD, percent removal was 87 percent.
This value is less than the permitted minimum value of 90 percent This deviation is being reported to the State of Florida in the Monthly Discharge Monitoring Report. A copy of the report is attached and is being sent pursuant to Section 3.2.1 of the St Lucie Unit 1 Environmental Protection Plan Should you have any questions on this information, please contact us Very truly yours J.

ATTACHMENTTO OSN 004 Florida Power & Light Company - St. Lucie Plant Wastewater Permit No. FL0002208 Outfall Serial Number: 004 September 1997 On Friday, September 12, 1997, samples were taken for CBOD, at the influent and effluent of the St. Lucie Plant Unit 1 Sewage Treatment Plant (STP).
These samples were analyzed offsite and, due to sample processing time, it was not determined until later in the month that the resulting CBOD, percent removal was 87 percent.
This value is less than the permitted minimum value of 90 percent.
FPL believes that increased numbers of personnel on the site for an upcoming refueling outage resulted in extra loading on the STP which, in turn, probably caused the upset. A resample of the STP on September 25,
- 1997, resulted in value of a 97 percent removal of CBODwhich is well within specification.
During the event, flow in the intake/discharge canal, which receives the Unit 1 STP effluent was over one million gallons per minute. Flow from the STP is typically less than 10 gpm, therefore, no adverse effect on the environment was observed or expected.
The Unit 1 STP ceased effluent discharge on September 27, 1997, when the sewers leading to the plant were re-routed to a recently constructed POTW.
