FPL - St. Lucie Plant State IWW Permit No. FL0002208 Request for Substantial Revision
Dear Mr. Harris:
Attached please find the following items to support the request for a revision to the Florida Power &
Light Company (FPL) St. Lucie Plant State Industrial Wastewater Facility Permit No. FL0002208:
- 1)
Four (4) signed, sealed copies of FDEP Form 62-620.910(5) 2CS, "Application to Discharge Process Wastewater from New or Existing Industrial Wastewater Facilities to Surface Water" with Attachments.
- 2)
An FPL Check payable to the Florida Department of Environmental Protection for the $7,500 application fee.
- 3)
An Antidegradation Analysis addressing the potential impact of the proposed modification.
FPL has received a modification to the existing Conditions of Certification under the Florida Power Plant Siting Act, as well as a previous State of Florida Industrial Wastewater Facility Permit minor revision (Permit No. FL0002208 - Minor Revision D) to add about 200 MW of electrical generation resources to its system in order to continue to provide reliable, safe, and cost-effective service to its customers. This increase will be accomplished by the St. Lucie Uprate Project (Project) which is an innovative application of technological advancements and efficiencies that will increase the net power output of both Unit 1 and Unit 2 from about 840 Megawatts (MW) to 943 MW each. The extra power output will result from improving the performance of the steam turbines and from using more nuclear fuel which will result in increased thermal MWs produced in the reactor cores. The additional heat will raise the temperature exchange between the primary and secondary systems, creating more steam for turning the turbines.
The Project consists of upgrades to each unit. The upgrades will include refurbishment and improvement activities to the steam turbine-electric generators, electrical systems, and cooling systems. These refurbishment and improvement activities will primarily occur during outages starting in spring of 2010 and will be completed during the spring of 2012. Certain improvements will also be made while the units are operating. None of the proposed modifications will involve land disturbance or new construction outside of the established facility areas.

St. Lucie Units land 2 use once-through cooling water from the Atlantic Ocean to remove heat from the main (steam-turbine) condensers via the Circulating Water System (CWS) and to remove heat from other auxiliary equipment via the Auxiliary Equipment Cooling Water System (i.e. Intake Cooling Water System). The great majority of this cooling water is used for the CWS.
Circulation of water in the CWS is provided by a total of eight circulating water pumps (four per Unit). Nominal design capacity of the pumps is 974,600 gpm, though actual flow may range from 800,000 gpm to 1,120,000 gpm, depending on system conditions. When all pumps are operating and both units are operating at 100% capacity, temperature rise across the condensers is approximately 25.7°F. After the uprate is completed, the CWS flow rate will be unchanged; however, the temperature rise across the condensers will have increased by approximately 3TF.
Temperature of the discharged cooling water is currently limited by the State of Florida Industrial Wastewater Facility Permit No. FL0002208. The current permit limits require that heated effluent from the diffusers, as measured near the "Point of Discharge" in the Discharge Canal, not exceed 113'F or 30'F above ambient during normal operations. A maximum temperature of 11 7°F or 32°F above ambient is permitted during certain maintenance operations, when throttling circulating water pumps to minimize use of chlorine, and when biofouling of the CWS occurs. The previously approved temperature rise associated with the EPU, in conjunction with increased Atlantic Ocean "ambient" temperatures observed over the past few years, are the reasons FPL is requesting in this application for a permit revision, that:
- 1)
The current 11 3°F instantaneous discharge temperature limit be revised to a 11 5'F monthly average limit and;
- 2)
The 30'F above ambient instantaneous maximum be revised to a 30'F monthly average.
If you have any questions or need additional information on this matter, please contact Ron Hix at (561) 691-7641.
