VEGP - OLSER INTRODUCTION Construction of the Vogt1e Electric Generating Plant (VEGP) began in June, 1974, and was discontinued in September, 1974, as a result of unfavorable economic conditions. Construction resumed in January, 1977, with excavation activities beginning in February. The plant site is approximately 3169 acres and located in Burke County on the southwest side of the Savannah River, the natural boundary between Georgia and South Carolina. The site is at river mile 150.9 across from the Savan-nah River Plant (SRP) operated by E. I. DuPont DeNemours and Company for the U.S. Department of Energy. The plant site is approximately 26 miles south-southeast of Augusta, Georgia. The site is located in the coastal plain which is characterized by sandy or sandy loam soil with rolling hills and mixed pine-hardwood association. Since the onset of construction, approximately 1391 acres of the site have been cleared for plant construction.

The original plans proposed a generating plant consisting of four units, but construction of two units has been cancelled. The plant will employ two pressurized water reactors producing 1160 MW each. Unit 1 is sche-duled to go into service in March, 1987, and Unit 2 in September, 1988.

The exhaust steam will be cooled by a closed-cycle cooling system employ-ing natural draft cooling towers using make-up water from the Savannah River. Low volume waste and b10wdown from both cooling towers will ulti-mately be discharged back into the river.

The Savannah River below Augusta, Georgia, and above the VEGP site receives wastewater discharges from municipalities and industries that add organic wastes, nutrients, metals, and other trace c~~5aminants. Stream classifi-cation near the VEGP is listed as "Fishing." The river near the plant site is typical of large southeastern coastal plain rivers, except that a dredged channel is maintained by the Corps of Engineers for barge traffic.

The biological community of the river is similar to that of other large southeastern rivers but has been affected by man's influence on the river.

The impoundment of the river above Augusta, Georgia, has reduced the trans-port of sediments and allochthonous particulate organic material, and the dredging of the channel has reduced the natural shallow areas and back-waters that would normally support a diverse flora and fauna. Studies on the Savannah River flora and fauna have bet~)conducted periodically since 1951 and were de{jt~~1 in Patrick, t§)a1., Academy of Natural Sciences of Philadelphia, and Matthews.

Georgia Power Company was required by the Plant Vogt1e Final E~~tronmenta1 Statement issued by the United States Atomic Energy Commission to com-plete the following requirements. The first requirement was to determine the extent of use of the projected areas of sedimentation by fishes for spawning and the effects of construction on spawning and on the suitability of the affected areas for future spawning. The second requirement was to predict the environmental impact of the intake canal and intake structure 1

VEGP - OLSER on the adult population of resident and anadromous fish in the Savannah River. A study began in September, 1977, and ended in December, 1978.

METHODS Five sampling stations were selected on the west bank of the river. Each was approximately 100 m in length and was similar to the shoreline of the proposed intake site. Stations I and II were located downstream from the proposed intake site (Station III), and Stations IV and V were located upstream (figure 1). Descriptions of each sampling station are given as follows:

Station I: Located at river mile 149.7 approximately 1.2 miles down-stream from the proposed site of the intake structure. The station consisted of sand bars, fallen trees, submerged tree stumps, and spurdikes. (Spurdikes are pilings placed in the river by the Corps of Engineers to control the meandering of the river channel).

Station II: Located at river mile 150.3 approximately 0.6 miles down-stream from the proposed intake structure. The station consisted of scattered overhanging tree limbs and submerged logs with very little additional cover for fish.

Station III: Located at river mile 150.9 and at the proposed site of the intake structure. The station was characterized by fallen trees. overhanging tree limbs, and a relatively straight shoreline with areas of shallow and deep water.

Station IV: Located at river mile 151.4 approximately 0.5 miles up-stream from the proposed intake structure. The station was a sandy beach-like area with no trees or submerged logs. During the study, the area was used as a spoil area as part of the periodic dredging of the channel by the Corps of Engineers.

Station V: Located at river mile 152.2 approximately 1.3 miles up-stream from the proposed intake structure. The station had many submerged logs and stumps. fallen trees. over-hanging tree limbs. and a combination of shallow and deep water.

Eight surveys were scheduled for alternating months. Samples were taken in September and December. 1977. and April, June. August, October. and December. 1978. Samples were not taken in February. 1978, because heavy rains resulted in high water levels. Sampling was done with a Smith-Root Vl-A e1ectrofisher mounted on a Va1co boat. Most species were identified. weighed, measured, and released in the field. Specimens which could not be identified in the field were preserved with ten percent 2

VEGP - OLSER formalin and transported to the Georgia Power Company Environmental Affairs Center Laboratory in Decatur for analysis. Dissolved oxygen concentration, conductivity, pH, air and water temperatures were mea-sured at the time of sampling to determine possible changes in water chemistry.

RESULTS AND DISCUSSION The family, scientific, and common names of fishes collected in the Savannah River are given in table 1. Thirty-nine species and 1109 indi-viduals were collected. The monthly results are presented in tables 2 through 9. The six species collected on all surveys were bowfin (Amia calva), redbreast sunfish (Lepomis auritus), spotted sucker (Minytrema melanops), spottail shiner, (Notropis hudsonius), bannerfin shiner, (Notropis leedsi), and whitefin shiner (Notropis niveus). The following species were collected only once during the entire study: flier (Cen-trarchus macropterus), threadfin shad (Dorosoma petenense), chain pickerel (Esox niger), white catfish (Ictalurus catus), dollar sunfish (Lepomis marginatus), striped bass (Morone saxatilis), taillight shiner (Notropis maculatus), and white crappie (Pomoxis annularis). This may have been caused by spawning migrations, as in the case of anadromous species; low numbers of individuals within a species; habitat preference; or the selectivity of the electrofisher.

The family Cyprinidae comprised 69.0 percent of the total number of individuals, with the Centrarchidae comprising 10.7 percent. The family Percichthyidae comprised only 0.1 percent and was represented by one specimen (table 10). Seventeen game and commercial species were collected, constituting 16.2 percent of the total number of individuals; whereas, the non-game and non-commercial species comprised 83.1 percent (table 11).

Table 12 presents the mean lengths in millimeters and the range of total lengths for each species for the months sampled.

The total biomass for the game and commercial species was 23,718.0 grams (g) (table 13). Striped bass comprised 4.3 percent of the biomass, while dollar sunfish comprised only a trace of the biomass. Biomass of non-game and non-commercial species was 124,417.0 g, or 83 percent of the total biomass which was 148,135 g (table 14). The greatest portion of the non-game and non-commercial species biomass was made up of bowfin with 43,099.5 g, or 29 percent, of the biomass.

Dahlberg and Scott(7)listed 100 species ~§ fish in the Savannah River drainage in Georgia. McFarlane, et al., )reported 69 species occurring (8) in riverine habitats in the vicinity of the plant site. McFarlane, et al.,

found the resident fish community of the intake canals of SRP similar to the river in terms of species composition. In terms of relative abundance, a distinct difference was noted from the community of the intake canals and the riverine community. The data from the SRP and Georgia Power Company studies showed the family Cyprinidae (minnows) to be the dominant family in 3

VEGP - OLSER the river. The dominant species in the SRP canals were the Centrar-chidae (sunfishes), which preferred slow-moving currents in lake-like habitats produced by the canals.

Under the stream classification of "Fishing,,,(l)dissolved oxygen concentration for warm water species of fish is a daily average of 5.0 mg/1 and no less than 4.0 mg/l. The required pH range is 6.0 to 8.5 with water temperatures not to exceed 32.2 C (90.0 F). Air tem-perature data recorded during the study ranged from 13.8 to 39.0 C.

Water temperature ranged from 13.3 to 26.0 C. Dissolved oxygen con-centration ranged from 5.6 to 7.5 ppm. The pH ranged from 6.0 to 6.9, and conductivity ranged from 38.0 to 65.0 micromhos/cm. The data for dissolved oxygen concentration, pH, and water temperature were all within the limits for the State of Georgia.

Construction of the intake structure began in March, 1981, with com-pletion scheduled for the end of 1982. The site of the intake is in a narrow portion of the Savannah River floodplain covered by second-growth vegetation. Construction consisted of clearing approximately 9 acres of land and digging a canal 414 feet long, 140 feet wide, and 13 feet deep at normal river elevation (80 feet ms1). Sheet piling positioned between the mouth of the intake canal and the river will prevent most sediment from entering the river during construction.

The construction of the barge slip has been cancelled, and a barge docking facility was constructed instead.

The cancellation of the barge slip construction should reduce the amount of area affected by sediment deposition. Spawning habitats may be al-tered temporarily or new spawning areas created. Whichever the case may be, the areas should be recolonized within a short period of time.

The Savannah River bottom is sandy and routinely dredged by the Corps of Engineers to maintain a depth of 9 feet for barge navigation.

The turbidity and sediment movement produced by the Corps of Engineers dredging may be as much or slightly less than produced by the construc-tion of the intake canal and barge docking facility. Those species which construct nests for spawning, such as the Centrarchidae and Ictaluridae, may be most affected by sedimentation. The nests could be covered by sediment destroying eggs and larvae.

Georgia Porfif Company concurs with the staff of the U.S. Atomic Energy Commission that no significant long-term adverse effects would result from activities associated with construction of the intake and discharge structures. This decision was based upon consideration of the periodic dredging activity by the Corps of Engineers and its effects on the fish community and the probability of recolonization of the effected areas downstream from the intake canal construction within a period of time.

An attempt to predict impingement losses at the VEGP was based on impingement studies conducted at the SRP. This was considered an 4

VEGP - OLSER appropriate approach since it would provide a better picture of potential impingement at the VEGP.

The data for the SRP showed that 36 species and a total of 469 fish were impinged in a twelve-month period for the three canals designated as lG, 3G, and 5G. Impingement rate~9yere estimated to be 11.2 fish per day, or 4,088 fish f~§ one year. In their study published in 1978, McFarlane, et al., )noted that for a ten-month period, 35 species and 347 fishes were impinged in the three canals. Eighteen American shad (Alosa sapidissima) were impinged during{IBj study. Spawning mortality of American shad was noted by Cheek in coastal streams of the South Atlantic states which may have been the reason for the dead fish on the intake screens. The most common species impinged were the bluespotted sunfish (Enneacanthus gloriosus), warmouth (Lepomis gulosus),

channel catfish (Ictalurus punctatus), and yellow perch (Perea flavescens).

Twelve species of Centrarchidae were impinged constituting 46.0 percent of the sample; while five Ictaluridae and three Clupeidae compri~81 13.0 percent and 15.0 percent, respectively. McFarlane, et al.,

further stated that while the 35 species were not impinged equally, there was no single species which predominated. In addition, the dominant species found in the canal did not constitute a corresponding fraction of the impingement samples.

River discharge is controlled by the four dams located upstream and operated by the Corps of Engineers. The SRP operates three pumping stations, two ten-pump units (lG and 3G), and one six-pump unit (5G).

The lG canal is 1640 ft. long, 98.4 to 229.7 ft. wide, with a minimum depth of 6.6 ft., depending on river elevation. The 3G canal is 1345 ft. long, 88.6 to more than 295.3 ft. wide, with a minimum depth of 6.6 ft. The 5G canal is in a cove 39.4 ft. wide and 65.6 ft. from the river to the trash racks. Minimum depth is 6.6 ft. Intake velocity (9) in front of the intake screens for the lG and 3G canals is 1.2 ft./s.

The proposed intake canal at the VEGP is 414 ft. long, 140 ft. wide, and 13 ft. deep at normal river elevation. At a river elevation of 80 feet msl, the velocity through the trash rack will be less than 0.5 ft./s, and through the traveling screens less than 0.7 ft./s. The intake structure will house four pumps (2 pumps per unit), each with a capacity of 22,000 gpm. Under normal conditions, approximately 40,000 gpm of water will be pumped from the river.

In a comparison of the impingement of fish at SRP with 33 power plants, only two plants had lower impingement. "The virtual absence among the impingement samples of small fishes commonly encountered in the intake canals, such as mosquitofish (Gambusia affinis), brook silverside (Labidesthes sicculus), and several minnows, indicate that ma~g)small, resident fishes have little problem in avoiding impingement." The NPDES 3l6{b) demonstration at the SRP was successful in demonstrating the adequacy of the plant's cooling water intake structures to meet the requirements of Section 3l6{b) of the Federal Water Pollution Control Act.

VEGP - OLSER Based on a combination of a single intake structure, lower intake velocities and short intake canal impingement at VEGP should be even less than experienced at SRP. Fish will be impinged at VEGP, but pre-dictions are that the number of individuals impinged will be low and that no single species will dominate the impingement sample.

CONCLUSIONS Georgia Power Company concurs(~tth the conclusion of the staff of the U.S. ~omic Energy Commission that no significant long-term adverse effects will result from activities associated with the construction of the intake and discharge structures. The areas of sediment depo-sition should be recolonized within a short period of time. Fish will be impinged at VEGP, but predictions are that the number of individuals impinged will be low and that no single species will dominate the im-pingement sample.
