4~13 NON-RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM The non-radiological environmental monitoring program applies to the m6hitorfng of the temperature-salinity distribution and the biological variables in the 10-mile segment of the James River Estuary centered at Hog Island.

The program is conducted in order to (1) 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; (2) to further verify the continued efficiency of the Ristroph traveling fish screens; and (3) to monitor the fish populations in the James River utilizing the data collected from the screens.

e

( 1.)

4.13.A.J TEMPERATURE AND SALINITY MONITORING 4.13.A.1.1 METHODS This program is conducted at monthly intervals using boat cruises along the scheme illustrated in Figure 4.13.A-1.

Sampling starts along the lntakes-Skiffes Creek transect just before low slack water, proceeds upstream, and concludes with the Jamestown lsland-Crou-:hes Creek transect.

At each station temperature and salinity are measured at two-meter intervals from surface to bottom.

4.13.A.1-l RESULTS Temperature and salinity measurements are shown in Figure 4.13.A-2 through 4.13.A-25.

e 4.13.A.2 4.13.A.2.1 CONTINUOUS WATER TEMPERATURE MONITORING METHODS Mfd-depth water temperature is measured in the intake canal at the high-level screens and in the discharge canal at the groin as illustrated in Figu~e 4.13.A-2.

Temperatures are recorded continuously on Taylor circular chart recorders located at each point.

Charts are changed weekly and temperatures digitized using a Hewlett-Packard 9864A digitizer.

e 4.13.A.2~3 Discussion There are very few preoperational data for comparison with 1979 values.

However, comparisons of the data in Table 4.13.A.2.2-1 do not show any major differences in intake temperatures.

Due to reduced station operations, discharge temperatures in 1979.were generally lower than those of other postoperational years.

Data for other postoperational years may be found in earlier operating reports.

e 4.13.A.3 CONDENSER-COOLING SYSTEM CHLORINATION Chlorine was not used in condenser cleaning_ and therefore no monitoring was performed.

4. 13.A.4 CHEMICAL RELEASES TO THE COOLING SYSTEM These data are reported monthly.

e 4.13. B 4.13.B.1 4.13.B.1.A FI SH SAMPLING MONTHLY BEACH DEINE AND OTTER TRAWL SAMPLING METHODS Sampling is conducted monthly at one otter trawl station located off the low level intakes and at two beach seining stations located immediately

,upstream (Intake N) and downstream (Intake S) of the low-level intakes (Figure 4.13.A.2-2).

The trawl sample is taken by towing a 3.1 m (diameter at mouth) trawl of 6.4 mm bar mesh in the cod for 10 minutes starting just off tile low-level intake structure with an ENE heading.

The beach seine samples are taken using a 15.2 m wide x 1.8 m deep of 6.4 mm bar mesh seine that is first stretched perpendicular to the shore, hauled 92 m and then brought ashore.

Samples are usually preserved immediately and then taken to the laboratory for identification and measuring.

Occasionally, when large or unusual fishes are caught, their catch is noted on the field sheet and they are immediately released.

4.13.B.1.B RESULTS Data for the monthly seine and trawl samples are shown in Tables 4.13.B.2.B-1 to 4.13.B.2.B-12.

A total column for the two seine stations is 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,2 4.13.B.2.A ADDITIONAL SEINE AND TRAWL SAMPLING REQUIREMENTS (Y1)

T.S.4.13.B requires additional samples at the stations (described in 4.13.B,2.A under the following circumstances:

(1)

If survival of fishes impinged on the Ristroph Traveling Screens falls below 75% on a given screen-sample day, seine and travel samples must be taken daily until survival rises above 75%;

(2)

If these screens malfunction or break down, weekly seine and trawl samples must be taken until normal operation resumes.

No daily low-level screen samples had less than 75% survival so no daily samples were taken.

During the week of February 18 the low-level screens broke down, a deviation report was filed, and seine and trawl samples were taken.

The screens returned to operation during the following week so the sample was used for the regular monthly sample as well.

No other situations required additional sampling.

4.13.s.3

  • DISCUSSION The data collected in the seine and trawl samples may probably best be analyzed by inspection of preoperational, earlier postoperational, and current samples from these stations.

Table 4.13.B.3-lA and B show the relative abundance of each species for each gear type during the preop.erational period, the postoperational period prior to 1979, and during 1979.

In order to reduce some of the variability caused by the different sample sizes, monthly means were computed for each period.

These means were then summed for the period and percentages calculated.

As might be expected, both the seine and trawl data show considerable variation among the minor species.

Although some species show an apparent decline (e.g., Alosa aestival is in the seine), and others increase (Leiostomus xanthurus e

in the seine), sti 11 others rise and then fal 1 in numbers ca_ught (Brevoortia tyrannus in the seine).

At the most, these variations can be con.;idered to reflect normal estuarine variability coupled with the effects of the recent severe winters of 1977, 1978, and 1979 and not due to power station operations.

4.13.C 4.13.C.1 RISTROPH (LOW-LEVEL) SCREEN MONITORING PROGRAM METHODS This program consists of two duplicate S-minute samples taken on either Tuesday, Wednesday, or Thursday of each week.

Fishes are collected in the sampling pool adjacent to the wash-water flume of the low-level screens.

They are then identified, classed as to model size, weighed and determined to be living or dead.

Weekly estimates of living and dead fiihes impinged are then calculated.

Additional sampling rs ;equi red if the survival rate falls below 75% (see also 4.13.B) and must continue until survival again exceeds 75%.

TS.4.13.E also requires the determination of the species responsible for the low survival and an analysis of the biological significance of the incident.

'-- J The Technical Specifications also require that additional weekly seine and trawl samples be taken in the event of screen failure, weather permitting (described in 4.13.B.1.A).

4.13.C.2 RESULTS.

Weekly impingement estimates are presented as Tables 4.13.C-1 through 4.13.c-52.

No additional screen samples were required due to low survival.

As stated in 4.13.C.1, additional seine and trawl samples were required due to screen malfunction only for the week of February 18.

The results of this sample are shown in Table 4.13.B.2.B-2.

During this week weather conditions were bad enough that it did not appear possible to conduct the required seine and trawl sampling.

Due to this possibility, a deviation report (Number 79-14) was filed on 2/21/79.
