..- e-4.13 fl0N-RADIOLOGICAL ENVIRONMEt!TAL MONITORit:G PROGRAM The non-radiological environmental monitoring program applies to the monit,orlog of the temperature-salinity distribution and the biological variables in the 10-n.ile segment of the James River Estuary centered at Hog Island. The program is conducted in order to further characterize the relationship between the thermal discharge and the physical-chemical characteristics of the water mass within the 10-mile tidal segment of the James River, and to monitor the fish populations in the James River utilizing the data collected from haul seine and otter trawl samples.

Reporting of data from the Ristroph traveling fish screens is required only in the event of mortality exceeding 25% and then directly to the Region 11 Office of Inspection and Enforcement.

Numerical sequences follow Technical Specification enumeration.

, e 4.13.A.2 TEMPERATURE AND SALlHITY MONITORING

! 4.13.A.2.1 METHODS This program is conducted at monthly Intervals using boat cruises

along the scheme illustrated in Figure 4.13.A-1. Sarpling starts along the Intakes-Skiffes Creek transect just before low slack water, proceeds upstream, and concludes with the Jamestown Island-Crouches Creek transect. At each station temperature and salinity are measured at two-meter intervals from
surface to bottom.

4 4.13.A.2.2 RESCI.TS Temperature and salinity measurements are shown in Figure L.13.A-2 through 4.13.A-25 4

Temperatures are recorded continuously on Taylor circular chart recorders located at each point. Charts are changed weekly and temperatuns are digitized using a Hewlett-Packard 9864A digitizer.

4.13.A 3/4.3 DISCUSSION During 1981, mean monthly intake temperatures were similar to those of the previous five years, in June, 1931, the mean temperature was 2 C higher i

than before, and in December, 2.5 C lower; otherwise, the temperatures varied witr'.1 +1.5 C.

Discharge temperatures were generally higher in 1981 with most being within +1.5 C. February and June were 3 C above average while July was 2 C higher. December was 3 C below average.

4.13.B FISH SAMPLlHG 4.13.B.1 MONTHLY BEACH SEl!1E AllD OTTER TRAWL SAMPLlHG h.13.B.1.1 METHODS Sampling is conducted monthly at one otter trawl station located of f the lo.v level intakes and at two beach seining stations located immediately upstream (Intake 11) and downstream (Intake S) of the low-level intakes (F i gu re I; .13. B.1- 1) . The trawl sample is taken by towing a 3.1 m (diameter at mouth) trawl of 6.1 mm bar mesh in the cod for 10 minutes starting just of f the low-level intake structure with an El4E heading. The beach seine samples are taken using a 15.2 m wide x 1.8 m deep x 6.4 mm bar mesh seine that is first stretched perpendicular to the shore, hauled 100 m and then brought ashore.

Samples are usually preserved immediately and then taken to the laboratory for identification and measuring. Occasionally, wSen large or unusual fishes are caught, their catch is noted on the field sheet and they are immediately released.

L .13. B .1.2 RESULTS Data for the monthly seine and trawl samples are shown in Tables

) 4.13.B.I.2-1 to 4.13.B.1 2-12. A total column for the two seine stations is i provided also. The tables show the catch for each species, the total catch of all species, the number of species for each station, and the diversity estimates H-Prime, Evenness, and Richness.

4.13.B.I.3 DIStussioil Tables 4.13.B.1-2 and 1-3 show the relative abundance of each species for each gear type during the periods of pre-operation, post-operation prior to 1981 and 1981, and allow an inspection of trends during these periods.

Among the nine most numerous seine species, four increased in abundance and five decreased. Of the eight trawl species that have amounted to at least 5% at some time, three increased and 5 declined. In both cases the Alosa spp.

continued their decline of the past several years. Brevoortia tyrannus, Micropogonius undulatus, Morone americana, and Notropis hudsonius decreased in one or both gear types while Anchoa mitchilli, Paralichthys dentatus and Trinectes maculatus increased. Many other species disappeared altogether.

These changes may mostly be attributed to the higher salinities encountered since June of 1980 that have been brought about by the extended drought of recent years (see the salinity data collected in boat cruises reported in Section 4.13.A.2 of this and earlier reports). The behavior of Menidia beryllina and M. menidia in the seine data reflects this reaction.

It;,menidia, the more salinity-tolerant of the two species, has increased while numbers of M. beryllina have declined. No changes in species composition appear that may be attributed to power station operation, l
