Dear Mr. Eisenhut:
This letter is to confirm infor:;,ation given by phone to Mr. Charles Phillips of the NRC on February 10, 1981, regarding the " Savannah River Fish Foculation Study and Impingement Prediction for Plant Vegtle, Burke County, Georgt " submitted to the NRC by letter of January 28, 1981.
1 Electric Fishina - Ecual EfforJ:
Five (5) electric fishing stations were established in the Savannah River, each station being 100 meters long. The number of electric shocks between each station varied due to the variation in fish habitats. However, approximately the same number of shocks were made in each individual station.
t Two passes were made at each station. The first pass included i
traveling the 100 meter length of the station and shock fishing each habitat. The second pass was identical to the first except that the second pass was slightly further from the bank.
Larval Fish:
i E
Georgia Power Company has data available on larval fish in the-Savannah River in the vicinity of Plant Vogtle.
(This information
~
is attached to this letter.)
There is also information in the i
Savannah River Plant (SRP) 316 - b report concerning fish larval.
Comercial Fishino for Catfish and American Shad:
i I:
- Georgia Power Company has no information concerning cocrercial I
fishing for Catfish or American Shad in.the Savannah River.
It is our understanding that the State of Ceorgia has approximately h[\\,
Ih years of data on comercial catches. This information can be Y. \\

GeorgiaPower A Mr. Darrell C. Eisenhut February 13, 1981 Page 2 Savannah River Plant Intake Flow vs. Plant Voctie Intake Flow:
The Savannah River Plant has three (3) intake canals, namely, IG, 3G, and SG. The maximum sustained flow for 1G, 3G, and SG is 16.4 cubic meters per second, 20.5 cubic-neters per second and 4.7 cubic meters per second, respectively.6 The maximum intake flow for all three intakes is 3.6 x 10 cubic neters per day which is 25% of tge minimum Savannah River flow. The normal intake flow is 1 x 10 cubig meters per day which is 7% of the minimum Savannah River flow.
The normal intake flow for Plant Vogtle for two units is 2.5 cubic meters per second.
Salt Water - Fresh Water Interface:
The salt water - fresh water interface in the Savannah River is located at approximately River Mile 21.
1 Corrections to the Study:
j Corrections and clarification to the study entitled " Savannah River Fish Population Study and Impingement Evaluation for Plant Vogtle, Burke County, Georgia" are as follows:
Page 8 and 9 - On pace 8 of the study a statement -is made that at SRP the intake velocity in front of the intake screens -for the IG and 3G canals is.38 meters per second...and that the velocity through the travelinc screens at Plant Vogtle is less than.2 meters per second.
We would like to clarify that the SRP. intake velocity is the velocity of the water as it accroaches the screens. The Vogtle intake velocity is the througn - screen velocity.
The.2 meters per second through - screen velocity would indicate that the Vogtle approach velocity is 1/3 to 1/4 the accroach velocity at SRP.
On Table.12, page 23, the 310 milliliter length for the species alosa aestivalis should be in the 4/1978.colunn and should not appear in the 12/1977 column.

Georgia Power d Mr. Darrell C. Eisenhut February 13, 1981 Page 3 On Table 12, page 23, the mean value of alosa sapidissira listed in the 9/1977 column should be 31 in lieu of 159.S.

Part 4 Savannah River Larval Fish Study 1NTRODUCTION A study was conducted to complete the requirement that fish eggs and larvae be sampled at suitable stations above and below the plant site in the Savannah River. The study was used to determine 1) what species spawned in the vicinity of the plant site and 2) the number of individuals.
MAT:..'ALS AND METIODS Three sampling transects were selected, each with two statiens.
Station 1 of each transect was on the Georgia side of the river and Station 3 of each transect was on the South Carolina side (Figure 4).
A description of each transect follows:
Trar.s ec t 151.-2 Located at river km 243.3 (river mile 151.2) and.5 km i
(.3 miles) upstream from the proposed site of the intake structure.
Transect 150.9 Located at river km 242.8 (river mile 150.9) and at the site of the intake structure.
Transact 150.6 Located at river km 242.3 (river =ile 150.6) and.5 km
(.3 miles) downstream from the proposed site of the intake structure.
Sa=ples were taken from January through May and July and August, 1974 Survey frequency for the months sampled are as follows: January 2 surveys, February 3 surveys, March 4 surveys, April 3 surveys, May 1 survey, July 1 survey, and August 1 survey. A total of 15 surveys consisting of 89 day samples and 88 night samples were collected. The data were grouped and presented as a menthly total. Densities were calculated by dividing the total number of eggs or larvae for a given l
..onth by the total volume of water filtered through the net Sampling
.a was done with a one meter diameter, 760,K' mesh, drif t net.
Sample duration time was fif teen minutes. Specimens were preserved in 100 f ormalin in the fie'1d and t:.),a to the Georgia Power Company Environmental Af fairs Center laboratory in Decatur for identification. Air and water i
temperature and dissolved oxygen concentration were taken at the time of

- RESUl.TS A"3 DISCUSSI The f amily, scientific and cemnon names of fish eggs and larvae collected in the Savannah River Larval Fish Study are given in Table 4 A total of 2177 larvae and 1423 eggs were collected (Table 44).
At least 34 species of fish were represented. Table 45 shows that a greater number of individuals were collected at night, with the exception of the tr. -
month of Iby. The larvae of the genus Pomoxis.co= prised 56.8 and 70.3%
of the February and !brch sa=ples, but only 7.5 and 3.2% of the April and July samples, respectively. Larvae of Minytre=a melanoes comprised 2.9,13.7 and 37.5% of the :brch, April and May samples.
Alosa sapidissima eggs first appeared in the March sample, comprising 5.0% of the total.
Peaks occurred in April (31.6%) and May (45.2%) with a sharp decrease in July (12.9%). For the 1974 study, the larvae of Pocoxis spp and Minytre=a
=elanops comprised the largest portion of the total number of larvae, with 48.4 and 25.9%, respectively. Alosa saoidissima eggs comprised 59.8% of the total nu=ber of eggs collected (Table 46). The densities of larvae and eggs for 1000 =3 of water Ad given in Table 47 for each family for each =enth sampled. The densities for the Clupeidae, Cato-scosidae, and Centrarchidae were the highest among the 12 f amilies represented. The density for the Clupeidae was highest in April and May, due primarily to the eggs of Alosa sapidissima. Catos'.omid density l
was also highest in April and May and consisted mainly of Minytrema melanops larvae.
Centrarchid density was highest in March, with a 3
density of 45.6/1000 m. Pomoxis sp-constituted the greater portion of a
the density of the Centrarchidae. Densities for the sonths sampled showed a gradual increase f rom January to April, peaking in }by with a i
sharp decrease in July and August (Table 48). Table 49 presents the mean lengths in millimeters and the range of total lengths for each species for the months sampled.
The air te=peratures for the day and night surveys are given in Figures 5 and 6.
The water temperatures for the day and night su rveys presented in Figures 7 and 8 show that temperatures never exceeded 32.2 C (90 F), the limit set by the Georgia Department of Natural Resources (1974). Dissolved oxygen concentrations, Figures 9 and 10, were also within the limit set by the Georgia Depart =ent of Natural Resources (1974) of a daily average of 5.0 =g/1, or no less than 4.0 =g/l at all times for warm water species of fish.

The study conducted at the SRP resulted in 1700 larval fish and 357 eggs collected, representing at least 22 species. The most common species were Aless aestivalis, Minytrena =cLneps, and Pe.exis ni::ro_
s maculatus. Nearly half of all larvae collected were clupeids, pri=arily I
Alosa aest ivalis. The eggs of Alosa sapidissima comprised 96.4*; of all I
eggs collected (McFarlane, et al. 1978),
i CONCLUSIC'l In our study, a total of 2177 fish larvae and 1423 eggs were collected, with a cinimum of 34 species represented. Alosa aestivalis comprised only.05% of the total nu:ber of larvae collected. The =ost co= mon taxa were Pomoxis sp'e. and Minytrema melanops, constituting 48.4 and 25.9". of the total number of larvae collected, respectively. The eggs of Alosa 7
1 sapidissima comprised 59.8*; of all eggs collected. The difference in e
the percent composition of Alosa sapidissima eggs in our study and that of F.cFarlane et al. (1978) is thought to be caused by annual spawning variations.
