fp~istX FLORIDA POWER 4 LIGHT COMPANY January 10, 1980 L-80-11 Office of Nuclear Reactor Regulation Attention: Hr. Harold R. Denton, Director U. S. Nuclear Regulatory Commission Washington, D. C. 20555

Dear Mr. Denton:

Re: St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 St. Lucie Plant Circulatin Water S stem As previously reported in the attached letters <of February 13, 1978 and July 3, 1978, Florida Power 8 Light Company has experienced higher than predicted circulating water discharge canal levels due to higher than anticipated ocean tidal levels combined with marine fouling of the subaqueous discharge pipeline. To alleviate this problem, FPL has proposed a modification of the St. Lucie III2 discharge pipe and headwall design by the attached application to the U. S. Army Corp of Engineers.

Plans for the modification have been submitted to the State of Florida Department of Environmental Regulation by the attached letter of August 8, 1979 and a hearing on the matter is scheduled for January 28, 1980 in Fort Pierce, Florida. The hearing relates to modification of the Florida Site Certification.

The Florida Power 8 Light Company Environmental Review Group has reviewed the proposed modifications and determined the construction activity will not result in a significant adverse environmental impact that was not evaluated and will not be significantly greater than that evaluated in the final environmental statement. FPL has further determined that the planned modification is bounded by the PSAR and will be described in detail in the FSAR/ER.

This letter is submitted for your information. We will continue to keep you informed of the progress of this activity.

Very truly yours, Pa@~
