September 28, 1981 Mr. Darrell G. Eisenhut, Director Division of Licensing Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D. C. 20555 Re: St. Lucie Unit 2 Docket No. 50-389

Dear Mr. Eisenhut:

'he Department of Environmental Regulation (DER) has reviewed the Environmental Report for the Operational License for Florida Power 5 Light Company ( FPL) St. Lucie Plant Unit 2. The changes in plant design that have occurred since the construction license was granted requires that the state license be modified.

Review of the modified multiport diffuser indicated that a mixing zone must be designated for the thermal discharge pursuant to Section 17-3.05, florida Administrative Code in order that the discharge be in compliance with the State water quality criteria. The DER proposes to designate a. thermal mixing zone of 10.7 acre feet. Special Condition II A.2 will be changed to read.

2. Thermal Mixin Zone The heated water dis har ed from the multi ort dif-fuser shall not exceed 17 F above ambient outside of a thermal mixin zone of .10.7 acre-feet; The mixin zone shall be bounded b an area.1385.5 feet ion extendin seaward from the most landward dischar e ort 21.0 feet to either side of the dischar e i e axis and 8.0 feet sn hei ht above the bottom of the dischar e orts.

After consultation with the Environmental Protection Agency the DER will be modifying other conditions of certification dealing with effluent limitations, monitoring and sewage treatment as illustrated below.
