. 1:

INTRODUCTION The Tennessee Valley Authority (TVA) started construction of the Phipps Bend Nuclear Plant following the issuance of the Limited Work Authorization (LWA) by the Nuclear Regulatory Commission (NRC) on October 18, 1977. TVA has developed a:.

implemented an erosion and sedimentation control plan and a construction effects aquatic monitoring plan as indicated in Part III, Sections G and I of the National Pollutant Discharge Elimination System (NPDES)

Permit No. TN0029301.

The aquatic monitoring program consists of onsite monitoring of surface runoff, monitoring of point source discharges identified in the NPDES permit, and limited instream biological monitoring. The program is tied to a feedback mechanism for implementing corrective action before significant adverse impacts occur in the Holston River. Should the results of the runoff monitoring indicate conditions that may have potential for producing significant adverse effects on the aquatic environment, onsite project personnel will be notified to implement corrective action.

This report is to evaluate the aquatic monitoring program for the second year (October 19, 1978 through October 18, 1979) of construction as required by the NPDES permit, Part III,Section I.

Included in this report are data from peripheral runoff monitoring, selected heavy rainfall sampling, ground water monitoring, instream aquatic macroinvertebrate monitoring, and aquatic macrophyte monitoring. Dates of site inspections are also included in Appendix A.

The monitoring of point source discharges as identified in Part I of the NPDES permit have been reported separately in accordance with the requirements in l

Part I.C.2.

l

l 2: SURFACE WATER RUN0FF Introduction Peripheral runoff monitoring was conducted on a prescheduled monthly 7

basis at four sampling locations (Figure 1).

Two stations were located on Stony Point Creek (miles 1.7 and 0.1).

The other two stations were points on an unnamed tributary to Stony Point Creek (miles 0.75 and 0.1).

Both Stony Point Creek and the unnamed tributary receive nonpoint runof f from the con-j struction site. Water samples were analyzed for temperature, turbidity, pH, and suspended solids (nonfilterable residue).

Precipitation records for the period between October 19, 1978, and October 18, 1979, were made by the onsite environmental engineer. When the l

rainfall intensity in the vicinity of the project exceeded 0.3 inches per hour or 1.0 inch par 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, the project environmental engineer notified the l

Water Quality Branch. Af ter notification of such occurrences, additional

" heavy rainfall" monitoring at the peripheral runoff sampling sites was con-ducted at the discretion of the Water Quality Branch. Dates of the peripheral runoff monitoring surveys both routine and those selected for heavy rainfall j

monitoring, are listed in Table 1.

Additional water quality monitoring was I

conducted following heavy rainfall events (March 7 and August 30, 1979) due to f

overflow of the yard holding pond. The overflows did not occur at the permitted pond discharge location (Figure 1).

i Results and Discussion 6

Peripheral Runoff Monitoring Monitoring data for calendar years 1978 and 1979 are summarized in Tables 2 and 3, respectively.

. The precipitation records for the reporting period are presented in Table 4.

The " heavy rainfall" criteria were documented on 14 occasions. Six heavy rainfall incidents were selected for peripheral runoff monitoring (see Table 1).

The results from these special samples are also included in Tables 2 and 3.

The routine peripheral runoff monitoring data were evaluated to detect differences in water quality between sampling locations upstream of the con-struction site and those downstream or on the construction site.

In most cases the suspended solids concentration and turbidity at the downstream location was higher than at the upstream location. The average suspended solids concentration and turbidity at the downstream location on Stony Point Creek was approximately 1.5 times greater than at the upstream location.

Likewise, the average suspended solids concentration and turbidity at the downstream location on the unnamed tributary was approximately 2.0 to 2.5 times greater than at the upstream location (significance of the effects on the Holston River are asscssed in sections 4 and 5).

These monitoring data were analy, zed for statistical significance using the t-test of paired observations. This analysis reveals that these differences were statistically significant at rather high levels of confidence (i.e., all greater than 80 percent). This evaluation together with the location of the sampling points indicates that it is reasonable to believe that con-struction activities increased the suspended solids concentration and turbidity i

of both the unnamed tributary and Stony Point Creek.

The pH of Stony Point Creek varied very little between upstream and downstream locations. The average pH at the upstream location was 7.6, while at the downstream location it was 7.7.

The pH at the downstream locatior af I

i l

l

O

, the unnamed tributary was usually higher than at the upstream. The average pH at the upstream location was 7.4, while the average at the downstream location was 7.6.

The heavy rainfall peripheral runoff monitoring data were also evaluated for upstream versus downstream differences in water quality.

In all cases the suspended solids concentration and the turbidity were higher at the downstream location on each stream than at the upstream location. The pH was usually very near the same at each location on the respective stream. The average suspended solids concentration and turbidity at the downstream location on Stony Point Creek was approximately 3.5 to 4.0 times greater than at the upstream location.

Likewise, the average suspended solids concentration and turbidity at the downstream location on the unnamed tributary was approximately 6.5 times greater than at the upstream location (significance of the effects on the Holston River are assessed in sections 4 and 5).

These data were also analyzed for statistical significance and were also found to be significant at rather high levels of confidence (i.e., all greater than 80 percent). This reinforces the previous conclusion that con-struction activities increased the suspended solids concentration and turbidity of both the unnamed tributary and Stony Point Creek.

Turbidity (up to 1000 JTU) and suspended solids (up to 1300 mg/1) values were generally higher for samples collected during heavy rainfall events than during the routine sampling periods. The onsite environmental engineer was notified of these analyses so that mitigative action could be initiated (e.g., seed and mulch slopes, rebuild straw dikes, etc.).

The peripheral runoff monitoring data for this reporting period compares closely to the preceding period (April 19, 1978 to October 18, 1978). As i

expected, the unnamed tributary to Stony Point Creek was generally higher in turbidity and suspended solids values than Stony Point Creek.

~

. i Overflow of the Yard Holding Pond On March 5,1979, heavy rains at the project over the weekend (2.58 inches) resulted in the overflow of the yard holding pond dike from a location 4

dif ferent f rom the pond discharge structure (serial 001). The overflow occurred at a point (Figure 1) where the top of the dike was below the 1

designed grade elevation (the dike was not up to grade at the time of the rainfall event as a result of subsidence) and below the elevation identified in the project's field environmental procedures for discharging from serial 001. Samples were taken of the sheet overflow at the dike on March 5 and 6 and at the point where the water entered the river on March 6.

The results are shown in Table 5.

On March 7, project personnel began pumping water from the holding pond. This action was taken to prevent significant erosion of the dike that may have affected its structural integrity and to provide needed storage capacity in the pond. To prevent tnc entrainment of excessive amounts of silt, the intake pipe for the pump was supported above the bottom sediments.

No additional samples of the pump discharge were taken since samples of the sheet overflow were taken on each of the previous two days (March 5 and 6, 1979) and were assumed to represent worst case. Two actions were taken to prevent the recurrence of overflows such as this in the future. First, the holding pond dike was brought up to design grade elevation. Second, improved interchange capacity between the cells of the holding pond has been provided.

In retrospect, because of the restricted flow conditions in the pond, the principal cause of the overflow was the inadequate interchange capability between the two cells of the holding pond.

On August 30, 1979, heavy rains at the project on the previous day (1.45 inches) again resulted in the overflow of the yard holding pond. The overflow occurred at a point (Figure 1) where recent activities associated with con-t

struction of the intake pumping station caused a small portion of the holding pond to be separated from the main body of the holding pond. This created a small pond with no outlet to the remainder of the pond. To prevent significant erosion of the dike that may have affected its structural integrity, project personnel pumped water from the small pond to the river from 2:30 p.m. to 11:00 p.m. on August 30.

Approximately 816,000 gallons of water were pumped from the pond. Samples were taken of the water being discharged and of the water entering the river. The results are shown in Table 5.

On August 31, f

1979, actions were taken to pump the water from the small pond to the main holding pond to eliminate the discharge to the river. A channel has been

~

constructed to allow water to drain from the small pond to the main holding pond.

Conclusions The suspended solids concentration and the turbidity of both Stony Point Creek and.the unnamed tributary to Stony Point Creek were usually higher at the downstream sampling location than at the upstream. This was true for both the routine and the heavy rainfall observations. Turbidity and suspended solids concentrations were generally higher for samples collected during heavy rainfall events than during the routine sampling periods. There were generally no significant differences in the pH of either stream. On two occasions during heavy rains, the yard holding pond overflowed into the Holston River at a point different from the pond discharge structure.

In both cases the turbidity

~

and suspended solids concentration of the overflow was high (significance of the effects on the Holston River are assessed in sections 4 and 5).

Immediate i

mitigative actions were taken in both instances to prevent similar occurrences.

3: GROUND WATER QUALITY Introduction Ground water quality was monitored in four wells at the Phipps Bend Nuclear Plant site (Figure 2).

A fifth well (212-P-170) was also to have been monitored, however, a damaged casing prevented collection of samples. At prescheduled quarterly intervals (Table 1), ground water samples were collected from each well and analyzed for selected minerals, nutrients, metals, and bacteria.

Samples were initially collected using a Kemmerer-type grab sampler.

In March 1979, samples were also collected using a portable submersible pump, where rassible. Data from the samples collected by both methods were compared and it was decided that the pump would be used where possible. On August 6, i

1979, however, the Nuclear Regulatory Commission issued a license amendment for the Phipps Bend Nuclear Plant which removed ground water monitoring as one of TVA's commitments in the Environmental Report. Pursuant to this change, ground water monitoring was discontinued.

j Results and Discussion The data from the three quarterly ground water quality monitoring surveys are contained in Table 6.

These data provide three sets of comparisons (in March 1979) of the two sampling methods which were used.

It appears that there were significant differences between paired data points for numerous parameters (e.g., well 4-P-172, suspended solids; well 105-P-171, COD; and well 204-P-173, NO +NO -N).

Although the differences were recognized, it was 2

3 decided to change sampling methods after March 1979 because it was believed that the pumped samples would be more representative of undisturbed ground water.

-g.

The quarterly ground water monitoring program did not demonstrate any unusually high concentrations of the constituents measured, nor were there major differences between observations at different wells or in

~'

different months.

Conclusions No long-term trends could be identified on the limited data collected but it is important to note that there were no unusually high concentrations i

of any constituent monitored during the 9-month period (October 1978-June 1979).

. 4: AQUATIC MACR 0 INVERTEBRATE COMMUNITY Introduction The aquatic macroinvertebrate community monitoring elevation program has been described in the June 1978 and December 1978, Phipps Bend Nuclear Plant Construction Effects Monitoring Reports. The monitoring frequency for this component is presented in Table 1.

Results and Discussion The macroinvertebrates colonizing the artificial substrates were collected at stations identified in Figure 3 during the period from April 1978 through September 1978 (Table 7) included 89 taxa (Table 8) representing 5 phyla and 20 orders. A complete listing of the quantitative enumeration data (mean number' substrate) and associated statistics of the taxa at each river mile are contained in Appendix B.

The most frequently encountered and most numerous taxa were:

(1) Cheumatopsyche sp., (2) Eukiefferiella sp., (3)

Hydropsyche sp., (4) Orconectes sp., (5) Pleurocera sp., (6) Stenacron sp.,

and (7) Stenonema sp.

The highest mean total number of organisms (447.0/ substrate), was obtained at HRH 120.2 in April 1979. The lowest mean total number obtained (0.5/ substrate) occurred at KRM 124.3 in January 1979 (Table 9).

The macroinvertebrate taxa collected from natural substrate sampling, July and September, are listed in Table 10.

Table 11 shows that the most frequently collected taxa were:

(1) Corbicula manilensis, (2) Crangonyx sp.,

3) Cricotopus sp., (4) Eukiefferiella sp., (5) Orconectes sp., and (6)

Pleurocera sp.

t

. l The molluscan and nonsolluscan biomass values recorded for the artificial l

substrates are summarized in Table 12.

Mean molluscan biomass values ranged l

from zero (HRM 124.3, January 1979) to 44,900 mg/ substrate (HRM 115.0, January l

l 1979). Nonsolluscan biomass varied from 0.87 mg/ substrate (HRM 119.0, November 1978) to 15,956 mg/ substrate (HRM 120.2, April 1979).

Diversity indices (3) and equitability value (e) for the macroinvertebrate fauna colonizing the artificial substrates at each station are presented in

(

Table 13.

The 3 value for the reporting period ranged from 0.73 (HRM 124.3, l

October 1978) to 3.88 (HRM 120.2, May 1979). The equitability values varied

, i from 0.27 (HRM 115.0, March 1979) to 1.20 (HRM 124.3, March 1979).

i The diversity indices (3) and (e) values were generally lower at HRM l

l 115.0 and HRM 119.0 than at HRM 120.2 and HRM 124.3.

In those instances when a lower than 2.00 was recorded, high numbers of either Pluerocera sp. or Ferrisia sp. were present on the substrate.

The comparison of the natural substrate samples with the artificial l

substrate by Sorenson's Quotient of Similarity shows extremely wide variation l

in the degree of similarity (Table 14). The results indicate that the artificial substrates were colonized by different communities than the natural substrate.

1 l

The 3 values, (e) values, total number of taxa and total number of organisms

[

per substrate tended to be higher during the spring and summer than in the fall and winter. Neither the molluscan nor the nonmolluscan biomass exhibited definite seasonal trends. The total numbers of taxa increased during the

^

1 l

second six months as did the nonsolluscan biomass at HRM 120.2 and HRM 124.3.

l i

The total numbers per substrate did not exhibit a marked change. The declines

~

in 3 and (e) values are attributable to the seasonal aspects of the community l

and the accompanying changes in dominant taxa.

4

. Conclusions The data show no consistent decline in totals numbers, biomass, d values,

.. o r (e) values occurred as a result of construction activities during the r

reporting period. Based on these results, it is concluded that the macro-invertebrate cosumunity of the Holston River has not been significantly altered by the construction activities at the Phipps Bend project.

, 5: PHIPPS BEND CONSTRUCTION MONITORING - AQUATIC MACR 0PHYTES Introduction d

The aquatic macrophyte monitoring program consisted of two surveys along 7 l the Holston River in the vicinity of the Phipps Bend construction site and the collection of species frequency data at HRM 119.9 and HRM 122.8 and the collection of standing crop data at HRM 119.9 and HRM 125.6 on May 24, 1979, and September 26, 1979.

In previous years, an aerial overflight was conducted during the fall for the purpose of obtaining color imagery to be used in the assessment of construction effects on aquatic macrophyte communities of the Holston River in the vicinity of the Phipps Bend site. However, the overflight was not conducted during the fall of 1979 due to extended periods of cloudiness, water turbidity associated with the high rainfall, and mechanical problems with the plane used in aerial overflights.

Results and Discussion Surveys of the Holston River in the Phipps Bend area show the macrophyte flora to be dominated by sago pondweed (pontamogeton pectinatus L.), American pondweed (P. nodosus Poir.), curlyleaf pondweed (P. crispus L.), waterstargrass Heteranthera dubia (Jacquin) MacM., tapegrass or eelgrass (Vallisneria americana Michx.), Canadian elodea (Elodea canadensis Michx.), and the aquatic mosses, Fissidens fontanus (B.-Pyl.) Steud. and Leptodictyum riparium (Hedw.) Warnst.

No significant changes were noted in macrophyte communities as compared to previous years, and no plants were observed to exhibit abnormalities in growth

(

or form.

~

. Ground truth surveys of the Holston River in the vicinity of the Phipps Bend site seem to indicate that there has been little change in the floristic composition and spatial distribution of aquatic macrophyte communities. The i

1977 macrophyte community map of the Phipps Bend area is representative of aquatic species along this portion of the river. While there have been no apparent changes in macrophyte communities due to construction activities, high turbidities were noted in tributary streams draining the construction site and could potentially impact existing communities along this portion of the river.

A standing crop of 221.8* g/m2 of ash free dry weight occurred at the upstream sampling station (HRM 125.6) during September 1979 compared to 176.3 g/m2 for May 1979. The species having the greatest standing crop at HRM 125.6 in May 1979 was sago pondweed with curlyleaf pondweed, Canadian elodea, and eelgrass comprising a substantial percentage of the total standing crop (see Table 15). Waterstargrass and sago pondweed were the dominant species during the September 1979 sampling period. The ash free dry weight at the downstream station (HRM 119.9) was 44.6 g/m2 in May 1979 and 148.2 g/m2 in September 1979 with sago pondweed and waterstargrass being the dominant species in May and eelgrass and' sago pondweed being the dominant species in September (see Table 15).

The increase in ash free dry weight f rom May to September at both stations is indicative of normal seasonal growth. However, the percent increase from May to September at the upper station (HRM 125.6) was less than that noted in previous years.

A comparison of the maximum standing crop at HRM 125.6 shows the 1979 estimate (221.8 g/m2) to be intermediate to the maximum standing

Estimates rounded to the nearest 0.1 gm.

i i

, crops of previous years (e.g., 1974-249 g/m2; 1977-136 g/m2; 1978-197 g/m2).

The 1979 estimate of 148.2 g/.n2 for the maximum standing crop at HRM 119.9 exceeds estimates for previous years (1974-52 g/m2; 1977-83 g/m2; 1978-41.4 g/m2).

Frequency data taken at HRM 122.8 showed sago pondweed, f.?amentous

)

algae, and American pondweed to be the dominants during the May sampling period with sago pondweed, filamentous algae, American pondweed, and aquatic mosses (Fissidens and Leptodictyum) being the dominants at the September sampling period (see Table 16). The increased frequency of the aquatic mosses (Fissidens and Leptodictyum) from May to September probably reflects seasonal growth. Filamentous algae, sago pondweed, and the aquatic mosses, Fissidens and Leptodictyum, were the dominant species at HRH 119.8 during both sampling periods (see Table 16).

Conclusions Variation in the species frequency data at the Phipps Bend site seem to be influenced by normal seasonal growth and climatic events rather than any factor associated with construction activities.

l

6: CONCLUSIONS I

The turbidity and suspended solids concentration of both Stony Point Creek and the unnamed tributary to Stony Point Creek (which receive runoff from the Phipps Bend Nuclear Plant construction site) were usually higher at the downstream sampling location than at the upstream.

Increased turbidity and suspended solids concentrations in Stony Point Creek could result partially from runoff not associated with TVA construction activities. Suspended solids i

discharged to the river by Stony Point Creek have not produced long-term detectable changes in the Holston River. This conclusion is supported by the fact that macroinvertebrate and macrophyte communities in the Holston River

.:,;= s did not demonstrate changes which can be linked to constre. tion activities at Phipps Bend.
