P. Ericks'on REVIEW.STATUS:
Continuing On April-=12, 1979, Florida Power and Light Company (FP8L) submitted a request to delete certain water quality requirements from the Appendix B Environmental Technical Specifications for St. Lucie Unit 1.
The licensee's justification, for deleting these requirements is that they are contained in the NPDES permit.
On September
- 7. 1979, Region III of the U.S. Environmental Protection Agency requested our review of changes to the St. Lucie NPDES permit proposed by FP8L.
These proposed permit changes are for the same parameters proposed to be deleted from the ETS.
The licensee provided EPA with an extensive environmental assessment of making the proposed changes.
In responding to EPA's request, we reviewed the assessment which FPBL sent to EPA.
At the same time we reviewed the portions of the NPDES permit which contain rest'ri ctions similar to those in the ETS.
Me find that we have no objections to th'e proposed changes to the permit.'e also find that we can rely on the NPDES permit for limiting those parameters which the licensee has requested to be deleted from the ETS.
Thus, we, have enclosed a letter for 'your signature to the Chief, Water Enforcement Branch of'Region IV<<EPA informing him that we do not object to the permit modifications and that we
'ntend to rely on the NPDES permit conditions for limiting those parameters
'eleted from our ETS.

Atlanta,'Georgia 30308
Dear Hr. Harlow:
He have reviewed the proposed changes to the NPDES permi t for the St.
Lucie Nuclear Power Plant as requested in your letter of September 7, 1979.
These proposed
- changes, to Page 2 of Part I (of Permit No. FL0002208),
are to increase the maximum discharge temperature and the maximum temperature rise of water passing through the condensers In addition, some thermal limits on the ocean mixing zone wi 11 be removed.
The licensee has provided justi fication for these NPDES permi t changes and has provided an extensive environmental assessment of the potential effects from increasing limits on thermal operating parameters at the plant.
Our review of this justification and environmental assessment indicates that the proposed increases will.not create a significant adverse impact in the site vicinity.
We, therefore, have no objection to the proposed changes to the NPDES permit.
, The changes proposed by Florida Power and Light Company (FP&L) to the NPDES perIIIit would normally result in changes to the NRC Environmental Technical
,Specifications (ETS) as our ETS, are consistent with the current permit.
- However, on April 12, 1979 FP&L requested modification to the ETS to delete some water quality limitations and monitoring requirements which are contained in the St. Lucie NPDES permit.
Their proposed request would eliminate thermal and chemical limitations and the surveillance requirements on chlorine, heavy
- metals, and pH.
We have enclosed a copy of the ETS containing the proposed deletions.
We plan to rely on the NPDES permit conditions as our review indicates that the conditions proposed to be deleted from the ETS are adequately covered by the permit.
We are in the process of preparing changes to the St. Lucie ETS

'P. Erickson RHVXBf STATUS:
Complete On August 31, 1976, the ORPH for the St. Lucie plant requested a revive of the monthly impingement reports for the first year of operation as required by Environmental Technical Specifications (ETS) 4.2.
By letter dated I~y 19, 1977, the lorida Power and Light Company submitted a report entitled, "Imping'ement of Aquatic Organisms" to complete the special reporting requirement of the St. Lucia Environmental Technical Specifica-tiono (ETS) 4.2.
Xn our preliminary review of the licensee's report (memo B. Grimes to K. Gol1er, January 30, 3978) we found that additional impingement data would be needed to fully assess t'e significance of fish impingement at the plant.
Ve requested that the licensee provide the impingement data for 1977.=
The licensee provided this data in its annual rcport for 1977.
Our review.of the impingement data collected during 1976 and 1977 indicates that the impingement monitoring requirement can be removed'rom the specifica-
- tion, Although this deletion has not. been requested by the licensee we are initiating this change after revieving the operating data.
Our Environmental, Impact" Appraisal which provides a summary of the MqIingement data and our Justification for deleting the program is attached.

>'OR ST. LUCIE UNIT '1 ENVIRONMENTAL TECHNICAL SPECIFICATION CHANGES Descri tion of Pro osed Action By letter dated May 19,, 1977, the Florida Power and Light Company submitted a report entitled, '"Impingement of Aquatic Organisms",
to complete the special reporting requirement of the St. Lucie Environmental Technical Specification 4.2.
Specification 4.2 requires monitoring of organisms impinged on the intake screens.
The data collected are 'to be analyzed monthly for the firstyear of operation and reports submitted for each month.
Our review (described below) of the impingement data collected during the first year of operation and the data collected in 1977 as submitted in the licensee's 1977 annual
.report shows that the impingement monitoring requirement can be removed k
from the specification.
Although this 'deletion has not been requested by the licensee we are initiating this change after reviewing the operating data.
This change is only for impingement monitoring at St. LucieUnit l.
Environmental Impacts of Proposed Action Specification 4.2 requires that intake screen washings be examined for-a consecutive 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period, twice a week.
The organisms collected are to be analyzed for the species
- present, number, -biomass and average size.
Plant startup occurred in Hay 1976, The licensee has collected impingement data from April through June 1976.
From July to September'976, the plant was shutdown so no samples were taken.
From September on, impingement monitoring has been conducted.
The licensee has submitted monthly reports covering the first year of operation.
Impingement monitoring data collected during 1977 was submitted in the licensee's 1977 annual report.
The 1977 annual report contains an extensive summary of the impingement monitoring results and the pxojected impact of the impinged fish on the local .
fish populations.
The 1977 report indicates that impingement averaged 223 fish and 74 shellfish per 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> sample period.
The predominant fishes collected during 1976 and 1977 were tomtate, anchovies and jacks.
The tomtate and anchovies are widespread and abundant in the plant vicinity but are not of sport or commercial importance."
Some species of jacks are of limited sport fishing potential.
However, the number of jacks collected in 1977 decreased from 1976, only constituting about 5% of the total number of individuals collected in 1977.
The predominant shellfishes collected P
on the screens were various shrimp species, blue crab, stone cxab and spiny lobster.
All of these species are of sport and commercial importance.
The shiimp comprised about 89% of the number of shellfishes collected while the blue crab accounted for about 10%.
The extrapolated total impingement while the plant was on line in 1976 and 1977 was about 69,000 fishes -in 1976 and 75,000 in 1977.
These numbers collected wexe a very insignificant part of the numbers of fishes in the site vicinity as indicated by the data from the farfield fish monitoring program for 1977.
The extrapolated total shrimp impinged while the plant was on line during 1977 was 22,110 individuals weighing approximately 100 lbs'.
This number is a very small part of the number of shrimp commercially caught off Florida's east coast (NOAA, 1977)*.
The staff concludes that the licensee's monitoring program and summary report of impingement at the St. Lucie plant are acceptable and that the impingement monitoring. requirement has been satisfied.
Impingement at the plant was not predicted in'he FES and the results of the impingement prediction.
for St. Lucie Unit 1 to be significant monitoring program verify the staff's Conclusion and Basis for Ne ative Declaration On the basis of the foregoing analysis, the staff concludes that there will be no environmental impact attributable to the proposed action.
The changes assessed herein are to the environmental monitoring programs and do not involve any change in plant design or operation or involve an increase in effluent types or quantities.
The impact of the overall plant has already been predicted and described in the Commission's FES for St. Lucie Plant Unit 1, On this basis and in accordance with 10 CFR Part 51.5, the Commission concludes that no environmental impact statement for the proposed J'ction need be prepared and a negative declaration to this effect is appropriate.
