INTRODUCTION Results of Northern States Power Company's (NSP) ninth consecu-tive reporting of environmental monitoring studies for the calendar year 1978 are contained in this publication. The 1978 calendar year represents the fourth full year of two-unit operation for the Prairie Island Nuclear Generating Plant (PINGP).
The 1978 annual report represents the final year of reporting for the following studies: Terrestrial Vegetation Study (Section 2.6), Small Mammal Study (Section 2.7), and Birds Killed Striking Transmission Lines (Section 3.1) . The terrestrial vegetation study indicates that other than con-struction activities the only power plant effects detectable are those associated with ice formation on trees adj acent to the plant cooling towers. Other changes in the vegetation community structure are associaced with natural succession.
The small mammal study has defined the magnitude of natural changes in the small mammal populations in the vicinity of PINGP and indicates no abnormal population or community structure alterations. The magnitude and species composition of birds killed by striking transmission lines have been adequately defined, and the results indicate that those lines perpendicular to bird migration routes have the highest proportion of bird kills.
Although not conducted in 1978, a fish creel survey will be conducted in 1979 by the Minnesota Department of Natural Resources (MDNR) Results of this study will be incorporated into the 1979 annual report, Prepared by:

PRAIRIE ISLAND NUCLEAR GENERATING PLAfrI' ENVIRONMENTAL MONITORING PROGRAM 1978 ANNUAL REPORT WATER CHEMICAL ANALYSES (1.1)

1.1 WATER CHEMICAL ANALYSES 1.
1.1 INTRODUCTION
Sampling was conducted by Environmental and Regulatory Activities Department personnel at Prairie Island. Parameters sampled included: phenolphthalein (p) and total (m) alkalinity, dissolved orthophosphates, total dissolved phosphorus, filter-able and nonfilterable residue, ammonia, nitrite and nitrate nitrogen, pH, conductivity, dissolved oxygen, turbidity, and temperature. Schmidt (1976) described each of the parameters and indicated its significance in water chemical analyses.
1.1.2 MATERIALS AND METHODS Samples were collected monthly at four stations (Figure 1.1-1).
Station E-l represents upstream main channel river conditions, X-1 reflects the quality of intake cooling water, Y-2 indicates water quality following plant usage prior to mixing, and Station C-4 represents downstream main channel river conditions, after mixing with plant effluent.
Samples were collected from top and bottom of the water column with a 6.2 liter Van Dorn water bottle and placed in new nlastic gallon jugs. Dissolved oxygen, pH, conductivity, turbidity, and temperature were analyzed at the Prairie Island Environmental Lab. The remaining parameters were determined according to Standard Methods (1975) by the NSP Chestnut Lab within 24-hours of collection. Instrumentation was similar to that used in previous years.

Chemical data were analyzed with a full factorial analysis of variance ( ANO VA) to determine seasonal, depth, and plant effects by combining data from Stations B-1 and X-1 (upstream) and comparing with data from Stations Y-2 and C-4 (downstream).
Missing values, caused by uncafe ice conditions at some stations during winter, were estimated according to Li (1964).
1.1.3 RESULTS AND DISCUSSION The 1978 Mississippi River water quality data and ANOVA are presented in Tables 1.1-1 and 1.1-2, respectively. The letters "T" and "B" appearing after the site locations refer to top and bottom samples, respectively. For each sample collected, annual mean, median, standard deviation, and range are also listed in Table 1.1-1.
Analysis of variance assumes that variability in chemical concentration is caused by seasonal variation, depth, and whether the sample was collected above or below the plant.
Some variation may also be caused by interaction between any two of these factors; the factors are not independent and together are contributing to changes in the parameters sampled.
Highly significant differences (P1 01) between upstream and downstream stations were observed for all properties except nitrite nitrogen, with regard to time (month of the year).
Nitrite nitrogen showed a significant difference (P5 05).
Temperature showed a highly significant difference with regard to plant effect. Ammonia showed a significant difference also attributable to plant effect.
1.1-4276 077
In 1976 and 1977 there were significant differences (P < .05) between upstream and downstream conductivity values. The 1977 difference was attributed to the fact that conductivity values had not been corrected for differences in sample temperature.
The 1976 figures were also not adjusted for the temperature differences. The 1978 figures were corrected for the sample temperature differences using the equation:
~
R 1 + 0 0 00 t- 25) '
where R = resistance of sample, ohms; C = cell constant; t= temperature degree C. No significant difference between upstream and downstream values was seen.
No other property analyzed showed any significant difference.

Ff#9180#00d PRAIRIE ISLAND NUCLEAR GENERATING PLANT ENVIRONMENTAL MONITORING PROGRAM 1978 ANNUAL REPORT WATER TEMPERATURE AND FLOW (1.2)
Prepared for Northern States Power Company Minneapolis, Minnesota DY L. W. Eberley Environmental and Regulatory Activities Department Northern States Power Company 1.2-1 2,7f ;
1.2 WATER TEMPERATURE AND FLOW l.2.1 INTRODUCTIr'v .*.ND METHODS This report presents daily maximum, minimum, and average water temperatures recorded by Resistance Temperature Devices (RTD's) in the vicinity of the Prairie Island Nuclear Generating Plant (PINGP). River inlet temperature is recorded at RTD1 and site discharge temperature at RTD2
( Fig ure 1.2-1). The RTD temperature sensors are spaced vertically at two-foot (0.6 m) intervals, with readings averaged by the PINGP computer and recorded hourly.
In addition, daily average site discharge flow (blowdown),
measured by PINGP personnel, and daily Mississippi River flow, measured at U. S. Lock and Dam 3 are presented. Daily average blowdown includes additional water appropriated to compensate for cooling tower evaporation loss (approximately 38 efs when all cooling towers and fans are operating).
1.2.2 RESULTS AND DISCUSSION Daily maximum, minimum, and average river inlet and site discharge temperature data are presented in Table 1.2-1 by month. Daily average river inlet temperatures ranged from 32.3 F (0.2 C) to 81.4 F (27.5 C) during January and August, respectively. Daily average site discharge temperatures ranged from 34.6 F (1.4 C) during January to 85.5 F (29.7 C) in August. Generally, daily average site discharge tempera-ture exceeded daily average river inlet temperature by three to five degrees Fahrenheit. Eberley (1977), however, indicated that under certain conditions, daily average river inlet temperature may equal or exceed daily average site discharge temperature due to recirculation of some of the heated water discharge.
1.2-3 276 103
Table 1.2-2 indicates mean daily and monthly site discharge flow (blowdown) recorded at PINGP during 1978. Daily mean blowdown ranged from 156 to 1,023 cfs. Mean nonthly blow-down ranged from 185 to 634 cfs. Daily Mississippi River discharge flow rates (Table 1.2-3) were somewhat atypical in 1978 due to heavy rains in late June and early July. One result of these heavy rains and the resultant cooler river temperatures was reduced plant intake flows. PINGP withdrew an annual average of approximately two percent of the Mississippi Piver flow (Table 1.2-4). Monthly withdrawal flows ranged from 0.5 to 3.7 percent in April and August, respectively.

2.1 1978 ATTACHED ALGAE STUDIES IN THE MISSISSIPPI RIVER NEAR THE PRAIRIE ISLAND NUCLEAR GENERATING PLANO 2.
1.1 INTRODUCTION
Periphytic algae of freshwater streams and rivers attach to a variety of substrata usually located on or near the shore. Factors influencing species composition and diversity include substrate, temperature, light, current, and water chemistry. Bacillariophyta (diatoms), Chlorophyta (green algae), Cyanophyta (blue-green algae), and Chrysophyta (yellow-green algae) make up the major groups of freshwater algae, with each group containing many species. Attached algae studies at the Prairie Island Nuclear Generating Plant concentrate on diatoms, since they constitute the largest po rtion of the periphyton community within the study area. Under natural conditions, one of the main factors in season-al succession of species is the different temperature optimums of species; and, as a result, as the temperature increases or decreases, replacement takes place (Patrick 1969). When natural conditions are altered and temperatures inecaase above ambient, there may be a shift in normal seasonal succession. Severe the rmal increases may cause the exclusion or certain species and other temp 7rature tolerant forms may dominate. Past studies of attached algae in the s t ud y area have indicated that temperature is the major factor affecting algal succession and community trends (Baker 1976). Data gathered during the 1978, the seventh year of the program, were analyzed, as in previous years, determining if any significant adverse impact occurred . 276 124 2.1-3
2.1.2 FIELD METHODS Field methods were the same as in previous years. Four glass microscope sl id e s installed in an acrylic plastic sampler were allowed to colonize for 14 days. Three sam-plers were placed at each of seven stations throughout the study area (Figure 2.1-1). Following each colonization period, all slides from each sampler were graded according to algal density; the densest slide, to be used in pigment analyses, being placed in a bottle containing 90 percent aqueous acetone solution saturated with magnesium carbonate. The three remaining slides were placed in a slide box and returned to the laboratory for quantitative analyses. Thus, three slides were used for pigment analyses and three fo r quantitative analyses at each station. Extra slides from each sampler were discarded af ter analyses. New slides were placed in the samplers and colonized for the next sampling period. Winter sampling allows only heated stations to be collected, sis.ce ice cond it io ns negates maintaining samplers in the main channel, intake area, and Sturgaon Lake, t LABORATORY PROCEDURE 2.1.3.1 Pigment Analysis Pigment analysis procedures t 'mained consistent with pre-vious years; samples were scraped, macerated, diluted to a known volume (25-200 ml), and centrifuged for ten minutes. The pigment extract was decanted into a four-centimeter cuvette and analyzed at 665 nm and 750 nm before and after ac id i f ic at ion using a Beckman DB-GT spectrophotometer. Chlorophyll a concentrations and phaeophytin a, the primary deg rad ation product of chlorophyll a, were determined by computer program utilizing the Lorenzen (1967) equation: 276 12<3 2.1-4
Chlorophyl a_ ug/cm = 26.7 [(665-750)" - (665-750)a] V (32.5 cm2) (4 cm light path) Phaeophytin a ug/cm 2 = 2_6.7 [1.7(665-750) - (665-730)"] V , (32.5 cm2) (4 cm light path) where: u = unacidified a = acidified 665 = chlorophyll a absorbance 750 = turbidity check absorbance V = acetone and chlorophyll a extraction vclume (ml). Results of the above computer analysis were expressed as micrograms chlorophyll a and phaeophytin a per square centimeter per 14 days. Percent chlorophyll a values were tabulated as follows: Percent chlorophyll a = (chlorophyll a/ chlorophyll a + phaeophytin a)100 2.1.3.2 Taxonomic Identification and Enumeration Miscroscopic analyses remained the same as 1977 methods; slides were scraped and the b io f il removed of all organic material by using nitric acid-potassium dichromate. Cleaned frustules were placed in a vial and diluted to 10 ml with d is tilled water. A thoroughly mixed sample provided a known 2 aliquot to be pipetted onto a 22 mm No. 1 coverglass. The coverglass was mounted on a microscope slide using Hyrax, labelled, and cataloged for microscopic analysis. Slide mounts were observed at 1000 x oil immersion using an American Optical Phase Star phase contrast microscope. Selected taxonomic keys were used to identify and enumerate species observed in 30 to 60 fields or until 100 of the most 2.1-5 b
dominant species were tallied. Raw data were then extra-polated to express cell density as the number of cells per square centimeter. 2.1.4 RESULTS 2.1.4.1 Phytopigment Analyses 2.1.4.1.1 Chlorophyll a Chlorophyll a concentrations at ambient stations during 1978 ranged from 0.00 ug/cm 2 at Station 6 on July 26 to 13.37 ug/cm 2 at Station 5 on May 17 (Table 2.1-1). Main channel stations exhibited chlorophyll a ranges from 1.12 ug/cm 2 at St at ion 1 on November 15 to 11.60 ug/cm 2 at Station 1 on September 6. Mean chlorophyll a concentration for main channel stations was 4.84 ug/cm2 , while ambient Stations 5 and 6 exhibited a mean of 3.35 ug/ Chlorophyll a/cm . Heated Stations 3, 4, and 7 showed chlorophyll a concentra-tion ranges from 0.04 ug/cm 2 at Station 4 on December 28 to 9.21 ug/cm 2 at Station 4 on October 4 (Table 2.1-1). Mean chlorophyll a concentrations were 2.85, 2.18, and 1.62 ag/cm 2 at Stations 3, 4, and 7, re spe c t iv ely . As in previous years, ambient stations had higher mean chlorophyll a concentrations than heated stations, 4.09 ug/cm at ambient stations versus 2.22 ug/cm at heated stations. Seasonal chlorophyll a biomass maxima occurred during early March at heated Station 3, while main channel peak chlorophyll a accumulation occurred in early September (Figure 2.1-2). This six-month separation in peak chloro-phyll a concentration represents the point at which r ive r water temperature reached optimum conditions for periphyton growth. Jptimal temperature regimes at both locatioDS ranged frc.n 20 - 23 C, occurring in early March at Sta-tion 3 and early September in the main channel. 276 127 2.1-6
Low chlorophyll a concentrations at Stations 5 and 6 during late July and early August are not indicative of normal periphyton growth. Extremely high river fl ow in 1978 (Figure 2.1-3) apparently uprooted a large portion of the aquatic macrophytes found in Sturgeon Lake. The uprooted pl ani_ s became entangled on periphyton samplers, forming a mat allowing insufficient illumination for periphyton colonization. 2.1.4.1.2 Phaeophytin q Phaeophytin a concentrations ranged from 0.02 ug/cm to 6.85 pg/cm d ur ing 1978 (Table 2.1-2). Ambient stations (1, 2, 5, and 6) had peak phaeophytin a concentrations during August, depicting the linear relationship between increased temperature and chlorophyll a degradation. Heated Station 3 showed peak phaeophytin a concentration during the May 17 sampling period, but high phaeophytin a to chlorophyll a ratios during August indicate this to be the peak period of chlorophyll a degradation. 2.1.4.1.3 Percent Chlorophyll a Percent chlorophyll a_ values during 1978 ranged f rom 0 to 99 percent (Table 2.1-3). Main channel stations averaged 90 percent chlorophyll a, ambient Stations 5 and 6 (Sturgeon Lake and Intake) averaged 73.5 percent, while heated sta-tions averaged 67 percent. The 16.5 percent difference between main channel Station and 2 and the other ambient stations can be attributed to increased flow and physio-logical richness of the main channel. The 23 percent reauction in percent chlorophyll a between main channel stations and heated stations indicates thermal stress within the immediate plant area. Heated Stations 4 and 7 had mean percent chlorophyll a values of 70 and 63 percent, respectively. This seven percent increase from Station 7 2.1-7 276 123
(immediate discharge) to Station 4 (Barney's Point) indi-cates partial recovery of community he al t h within even a short distance. Extremely low percent chlorophyll a_ values at Stations 5 ana 6 during July are probably related to the shaaing effect caused oy agoatic macrophytes entangled in the samplers. Visual observation of the samplers showed little or no algal growth due to s had ing and abrasion by aquatic macrophytes. 2.1.4.2 _ Microscope Analyses Attacned diatom cel l density during 1978 varied frcm less than 8,000 cells per square centimeter to more than two million. Cell density at all stations for all sampling periods is shown in Table 2.1-4. Minimal cell densities occurred during winter months at Station 4 (Barney's Point), while maximum densities occurred at differing times, de pe nd ing on s t a t io n . Main channel station maxima occurred during September, with a secondary peak during May. Heatea stations peaked during March with a secondary peak in May. Ambient Stations 5 and 6 had a May peak with a smaller peak during September. Maximum cell densities are regulatea by temperature; opt im al temperatures giving rise to peak cell densities of each seasonal community. Table 2.1-5 lists all diatom species id e n t i f ied since the initiation of the PINGP attached algae program. The list now includes 220 species from 34 genera. Diatom analysis for 1978 presents spe cies representing two orders, Centrales and Pennales. Each order has certain genera that are present at all stations. These include Cyclotella, Melosira, and Stephanodiscus from the Order Centrales; cnd Diatoma, Fragilaria, Gomphonema, Navicula, Nitzschia, and Synedra from the Order Pennales. 276 129 2.1-8
Seasonal s uc ce s s io n of the attached algal community is d iv id ed into four groups; winter, spring, summer, and late summer (Baker 1976). Each of these groups has certain dominant species indicative of the thermal conditions of the season. The winter community was dominated by Fragilaria intermedia, Diatoma vulgare var. producta, and Nitzschia acicularis at heated stations. Ambient stations are not accessible during winter months, giving no taxonomic profile of these stations. The spring diatom community was dominated by Synedra (S. acus) and Gomphonela (G. parvalum and G. olivaceum) genera. Peak concentrations occurred during March in the recircula-t io n canal and May at ambient stations. Certain species of Gomphonema occurred at various times throughout the year, but no significant peaks were reached. Summer diatoms were characterized by Navicula (N. cincta) and the centric genus Cyclotella. These species tolerated high temperatures in the main channel, but the even higher temperature within the recirculation canal caused a dip in cell density. Late summer forms included Navicula cincta, Nitzschia acuta, and Nitzschia tryblionella. These species were encountered during September in the main channel, but densities within the recirculation canal at the same time were much lower. A] l diatoms comprising the seascnal community of attached algae operate within a temperature regime indicative of that species. A shift in temperature from optimum to a point outside the regime will cause one species to subside, whereas another form will dominate if tLe temperature is conducive to its grcwth and reproduction. 2.1-9 26 130
2.1.5 DISCUSSION Community structure and seaso nal trends exhibited by the attached diatom community during 1978 reflect the response of algal species to opt imum temperature cond i t io ns . Other factors that may influence algal growth include light, nutrients, and substrate. As in previous years, heated stations had peak chlorophyll a and cell density during January t.h r oug h March. Ambient main channel stations had peak chlorophyll a and cell density during September. Optimum temperature range for both areas was 20 - 23 C. Chlorophyll a and cell density were low during June and July, especially evident at Sturgeon Lake and intake sta-tions (5 and 6). River flow during 1978 was much higher than 1977, causing an over abundance of aquatic macrophytes ta be uprooted and carried downstream. This vegetation became eatangled in the periphyton samplers, causing abra-sion of the substrate and shading of the entire sampler. Comparison of field notes and laboratory results indicates the vegetation was probably responsible for low periphyton growth. Periphyton growth generally followed normal seasonal pro-files indicative of the Mississippi River near PINGP. Data gathered over the last years have given a detailed account of species composition and chlorophyll pigments as they react to ambient river cond it ions and heated effluent from PINGP. Thermal ef fects have always been most evident in the recirculation canal, close-in discharge, and to a lesser extent at Barney's Point. The most evident effect seems to be a shift in peak cell density, community rtructure, and phytopigment concen tr a t ions . Rapid mixing of the effluent below Barney's Point, especially that of U. S. Lock and Dam 3, indicates a return of the community to normal am b i c .'. t structure immediately downstream of the plant. 276 IM 2.1-10

2.2 BENTHIC MACROINVERTEBRATES 2.
2.1 INTRODUCTION
This report of the benthic saacroinvertebrates of the Missis-sippi River at Prairie Island is the ninth in a continuing monitoring program for Northern States Power Company's (NSP) Prairie Island Nuclear Generating Plant (PINGP) near Red Wing, Minnccota. This annual report presents analysis and interpretation of 402 benthic samples collected during the fitth year of plant operation, spanning the period January through December 197E<. The pr ima ry objective of the study is characterization of the benthic community in the vicinity of PINGP, with respect to any effects which may be attributable to opera-tion of the generating facility. To meet this objective, a s tud y program was designed in which any major alterations in community integrity directly attributable to plant operations could be segregated from natural community fluctuations. 2.2.2 MATERIALS AND METHODS 2.2.2.1 Field Sampling Regularly scheduled benthic macroinvertebrate samples were collected by Northern States Power personnel during 1978. Two types of samples were collected :
- 1. Petersen dredge samples (every 6 weeks from February through November)
- 2. Artificial substrate (Hester-Dendy) samples (every 6 weeks from January through December) 276 166 2.2-7
The Petersen dredge was used to collect sedentary substrate dwelling organisms. Petersen dredge samples were collected at Stations B-1, SL, X-1, X-3, Y-1, Y-2, C-1, and C-4 (Figure 2.2-1). The Hester-Dendy multiplate sampler (artificial substrate) was used to sample benthic organisms which prefer a rigid substrate. Artificial substrate samples were collected at Stations B-1, SL, X-1, X-2, X-3, Y-1, and Y-2 (Figure 2.2-1). Petersen dredge sampling consisted of tnree rep.licate grabs at each station using a dredge sampling 1.0 ft. 2 Samples were washed in the field using a No. 60 mesh sieve and preserved in 37 percent formalin. Artificial s. * . ate samples were collected using a Hester-Dendy multiplate campler consisting of eight tempered hardboard plates with a aurface area of 1.0 ft 2 (Hester and Dendy 1962). The samplers we re anchored with concrete blocks suspended from surface floats and incubated for approximately six weeks. At each station, four samplers were installed in two sets at two a n.d four feet below the surface, respectively. After the six-week incubation period, samplers were removed and organisms sieved and preserved in the same manner as Petersen samples. All samples were then shipped to the Dallas sample pro-cessing f acility of Texas Instruments. Data were analyzed by Texas Instruments personnel and subsequently couputer processed to final form. 2.2.2.2 Laboratory Analysis Before analysis, samples were washed through a No. 60 mesh screen, which removed most of the remaining sediment and preservative. The contents of each sample were then sorted according to general aiv rr holog ic al characteristics to 2.2-276 167
facilitate efficient processing of bulk samples. Samples were placed in a sorting tray or petri dish, depending on sample size, and systematically scanned under 10X magnifice-tion. Organisms displaying similar morphological features were placed in vials containing 70 percent ethanol for later identification and enumeration. For extremcly denF2 artificial substrate samples, a TI-modified Folsom plankton splitter (Scarola and Novotny 1968; Lewis ;ns Garriott 1970) was utilized to obtain statisti-cally representative subcamples. During 1978, 86 multiplate samples were split. This procedure was designed to yield a subsamnle of workable density while maintaining a high
- evel of precision. Appendix A2.2.1 presents the rationale and justification for this subsamb vg procedure. In addition to those samples listed in Appendix A2.2.1, 14 additio 21 samples were checked to verify splitting preci-sion. Sort ing procedures are the same for subsamples as chose liated a we for entire samples.
Sorted samples were placed in d iv id ed petri dishes, where all taxa were enumerated and identified using a stereozoom d is se ct ing microscope equipped with an ocular micrometer. When necessary, a compound microscope supplemented the dissecting microscope. Only those organisms whose dimen-sions exceeded the mesh size of the screens were quantified. Orgar. isms were id ent i f ied to the lowest practical identi-fication level (LPIL), usually genus, but higher levels of identificatior. were made for certain minor taxa that required extremely dif ficult taxonoraic delineation. 012g0-chaetes and chironomids were mounted on slides with floyers mounting media ( Ro back 1957; Kn ud se n 1966) for identifica-tion purposes. Enumeration involved only ind iv iduals living at the time of collection (indicated by the presence of fleshy tissue) . In 2.2-9 276 168
instances when organisms (such as oligochaetes) fragmented due to preservation and handling, only anterior portions were enumerated. Principal taxonomic keys used in the identification of benthic macroinvertebrate taxa were: Ward and Whipple (1959), Pennak (1963), and Usinger (1971). These were supplemented by monographs specific to the systematics of locally occurring organisms and/or specific groups of taxa (see asterisked references in Literature Cited, subsection 2.2.6). 2.2.2.3 Data Analysis Data obtained from the benthic portion of this study were used to generate a presence / absence list of benthic macro-vertebrates for each month studied. Numerical abundance data were calculated as total number of organisms per collection (No./ft ), extrapolated, and expressed as a mean number (by species and total) per square meter. Standard errors for each set of replicate samples were also computed for each station. Rela t iv e abundance (percent) data were expressed as the percent that a par-ticular ta::on comprised of a total sample. Evaluation of these data provided information on species and number per unit area, relative composition during each sampling period, and normal seasonal population fluctuations. Using the Shannon-v- ** i .ormational measure of diversity (H') (Shannon a- 2" 1949), a diversity value was calculated for es s ai6 p 'm collected. This value was compared (as a ratio) to the m&"imum theoretical diversity of the sample to obtain a measure of " evenness" (J') of distribution of inc i v iduals among the various taxa (Plelou 1969). 2.2-10 2[O $b
2.2.2.4 Statistical Analysis In order to accurately characterize phenomena observed in the data, a series of statistical analyses was performed. These analyses were designed to determine significant trends and patterns that existed in the data, primarily significant variances in the data that may be attributable to plant operation. Sampling with the Elester-Dendy multiplate sampler was not consistent throughout the year due to icing cond it ions in the winter months and very high flow conditions during spring months. Ilowe ve r , there were subsets of months and stations that formed consistent blocks of data. Three such " blocks" were used to compare stations as shown in the following table: Station-Month Combination Stations
- Station Station Station Month Sampled 1-7 2-7 3-7 1 2-7 x x 2 2-7 x x 4 2,4-6 5 1-7 x x x 7 1-7 x x x 8 1-7 x x x 9 2-7 x x 11 1-7 x x x 12 2-7 x x

Petersen dredge sampling was consistent throughout the year with three subsets of months necessary to compare stations. These data " blocks" are shown in the following table: Stat ion-Month Combinations Stations

C-1; 8 - C-4 The Newman-Keuls multiple range test (Winer 1971) compared mean densities against background sampling variation to determine which stat io n( s ) were statistically distinguish-able. Since there were no occurrences of zero densities in Petersen dyedge samples, the log 10( " # " #* " could be used without further modification for this gear. The occurrences of zero densities at Stations X-1 and Y-2 for artificial substrate samples in January necessitated use of a log aa ans fo rma t ion to oMan mean6ghl 10 comparison data for this gear type. Logarithmically-transformed data yielded a comparison of relative orders of magnitude rather than absolute densities, and tended to stabilize variance. Newman-Keuls multiple range tests were performed for the monthly means for each ANOVA. 2.2-12
2.2.3 RESULTS 2.2.3.1 Petersen Dredge Sampling Taxa Inventory / Seasonal Occurrence Benthic macroinvertebrate ecllections ( Petersen dredge) yielded 78 taxa, with chironomid (midge) larvae comprising the major portion (Table 2.2-1). Organisms appearing most ubiquitously throughout the study period were Nematoda, Tubificidae (Oligochaeta), and the chironomids Chironomus, Cryptochironomous, and Procladius. The prevalence of these organisms in 1978 collections is consistent with the last two years' findings (Texas Instruments 1977 and 1978) in which these organisms were well distributed both spatially and temporally throughout the study area. As in previous yearc of study in this area, a broad assem-blage of pollution-tolerant (i.e., Chironomus, Cryptochiro-nomus, and Tubific id ae [ Oligochaeta] ) , f acul tativ e (i.e., Caenis, Plumatella repens, and Polypedilum), and intolerant (i.e., Ablabesmyia, Psectrocladius, and Hexagenia) macro-invertebrate taxa (Weber 1973) were collected. Taxa occur-ring in the area are generally characteristic of benthic assemblages in moderate current, soft-substrate rive rine environments (Hynes 1970). Numerical Abundance The temporal density pattern was not consistent for all stations d ur ing 1978 (Figure 2.?-2). The upriver control station (B-1) and down r iv er control stations (C-1 and C-4) exhibited s imil ar seasonal density patterns in which peak densities occurred in the March sampl ing period. Due to high river flows (Figure 2.2-6), which scoured the main channel bottom substrates, Stations B-1, C-1, and C-4 2.2-13
exhibited markedly reduced organism densities for the May through November sampling periods. Densities at the recirculation canal station (X-3) were consistently low throughout the year. Stations located at Sturgeon Lake (SL) and the p' an t, intake (X-1) displayed similar trends in density with numbers increasing from February through June, declining in July (no samples were analyzed for SL in July) and September, increasing significantly in October and, finally, declining again in November. Peak values for Station SL were reached in June and October, whereas Station X-1 reached its maximum values in May and June. Station Y-1, discharge canal, registered an annual peak in February, then remained fairly constant at a lower level from March through June before declining to an annual low in July. Densities remained low at Y-1 in September be fo re reaching a secondary peak in October, then declined in November. Station Y-2, also in the discharge canal, exhibited an annual low in February with densities thereaf ter increasing each sampling period to a m ax imum in July. Density values for Station Y-2 then declined through October before in-creasing in the November sampling period. As in 1976 and 1977, the intake station (X-1) compared favorably with the upriver control station (SL). Also, as in the two previous years, the recirculation canal station (X-3) displayed sustained low values o/er the course of the year. The discharge canal stations, Y-1 and Y-2, reflected generally increasing densities relative to the recirculation canal, with Station Y-2 exhibiting the highest density values of all stations sampled during the year ( 12,7 5 9. 2/m 2 in June and 12,960.1/m 2 in July). Stations B-1, C-1, and C-4 displayed s imilar trends in density during the year. Densities for these stations were the highest of all sampled stations in March (Table 2.2-2), but thereafter, were generally lower than all stations except the recirculation canal (X-3). Total density values ranged from 10.8/m 2 at 2.2-14 2]O k
Station C-1 in September to a maximum of 12,960.1/m 2 at Station Y-2 in July (Table 2.2-2). These values can be compared with ranges of 0-10,079/m' and 75.3-17,947.6/m 2 2 observed during 1976 and 1977, respectively (Texas Instru-ments 1977, 1978). Percent Composition As in the previous two years of study (Texas Instruments 1977, 1978), tubificid oligochaetes and dipterans, primarily Ch ironomid ae (midge larvae), dominated the Petersen dredge collections in the study area during 1978 (Table 2.2-3; Figure 2.2-2). Tubificids represented 69.0 percent of all organisms collected, while dipterans constituted 24.8 per-Cent of the total. Collect iv ely , these two taxa contributed 93.8 percent to the total number of organisms in 1978. Tubificid worms were abundant at all sampled stations except the recirculation canal (X-3) during the February and March sampling periods. Tubificid abundance at X-3 remained low throughout the year, reflecting the unstable substrate and turbulent water flow conditions that characterize this station. Beginning in May and extending throughout Novem-ber, the upstream control (SL), intake (X-1) , and discharge (Y-1, Y-2) stations exhibited similar tubificid abundance patterns. The upr ive r control (B-1) and downriver control (C-1, C-4) stations also exhibited similar patterns of tubificid abundance, in that numbers were generally reduced from 1976 and 1977 levels in response to unusually high river discharge (Figure 2.2-6). The scoured cond it ions at these stations and in the recirculation canal indicate that substrate stability and river discharge are two major factors controlling tubificid abu nd e r.cc and distribution in this area. The fact that the upstream control station (SL) is comparable with the intake (X-1) and discharge (Y-1, Y-2) 2.2-15
stations would suggest, as in past years, that plant opera-tion is not a major factor influencing tubificid r'andance and distribution. Procladius, Cryptochironomus, Chironomus, and Polypedilum were the dominant chironomid (midge) larvae co' acted during 1978. This compares favorably with 1976 and 1977 data (Texas Instruments 1977, 1978). As with tubificid worms, densities of chironomid larvae were markedly reduced at the recirculation canal station (X-3) further emphasizing the lack of suitable habitat at this location for the most abundant organism groups in the study area. The compara-bility in terms of abundance and density of chironomids of upstream control s tat io n (SL) with intake (X-1) and dis-charge (Y-1, Y-2) stations suggests that plant impact is localized in the recirculation canal, and that normal population structure is maintained at othe r stations in the study area. Community Diversity Seasonal variations in community diversity (H') and eveness (J'), are affected by density, the number of taxa collected, and the d istr ibu t ion of densities within the various taxo-nomic groups. The H' index has a range of 3.31 log N (N= 2 number of taxa), with an effective range of 0 to 4 in most freshwater s i t ua t io ns . The J' index has a range of 0 to 1, with a value of 1 being a completely evenly d istributed (i.e., equal numbers of individuals in all taxa sampled) po pul a t io n . Community diversity values (H') (Figure 2.2-3) generally exhibited the lowest v4. lues of the year during months of extremely high tubific.d percentage composition (i.e., February, March, and May), and had the highest values where chironomid percentage composition was high (i.e., September, 2.2-16
October, November). Values of H' ranged from 0 at Station X-3 in May, when only one taxon was encountered, to 3.08 at Station C-1 in November, when 19 taxa were collected. This range in diversity values is greater than that observed in 1977 and 1976, when max ima of 1.17 and 2.53, respectively, were recorded (Texas Instruments 1977, 1978). Evenness (J') values ranged from 0 to 0.90 (on a scale of 0 to 1) corres-ponding to H' min im a and maxima, r e spe ct iv ely . Relative to 1977, the increase in benthic community diversity measured in 1978 can largely be attributed to decreased densities of t ubi f icid worms from the very numerous levels during 1977 and to the occurrence of midge larvae in the samples over a longer time than in the previous year. Statistical Analysis The data were analyzed in three subsets, because in certain months, all stations were not sampled. The Newman-Keuls multiple range test was applied to station means. Logarith-mically transformed data were used to stabilize variances and provide for o rd e r-o f-m ag n i t ud e comparisons among sta-tions. Results of statistical analyses for 1978 data are presented in Table 2.2-4. Comparisons among intake ( X -1 ) , recirculation (X-3), and discharge (Y-1 and Y-2) stations for all sampling periods reveal that X-3 differs significantly (a= 0.05) from the other three stations, with much lower densities. Stations X-1, Y-1, and Y-2 were not distinguishable from each other for the data set including these stations and all sampled months for both transformed and untransformed data. Using the transformed data set for all stations and the months March, May, June, S e pterabe r , October, and November, a comparison across all stations indicates that upstream control stations (B-1 and SL) were indistinguishable, in 2.2-17 }/g )/
terms of total density, between each other and from the intake (X-1) and discharge stations (Y-2 and Y-2). Differ-ences in total density among the upstream control (B-1), discharge (Y-1), and downstream control (C-4) stations were not distinguishable. The corresponding un trans fo rmed data show no significant differences in total density among upstream control station (B-1), recirculation canal station (X-3), and downstream control stations (C-1 and C-4). Untransformed data for all months except February and July and all stations except SL (Table 2.2-4), depict only discharge Station Y-2 as significantly dif ferent from other stations in the study area. Transformed data for the same months and stations show no differences between the recir-culation canal station (X-3) and downstream control station (C-1), but significant differences exist between these two stations and all Jther stations in this subset. In summary, the statistical analyses indicate that varia-tions in infaunal density patterns may be introduced bv plant-related activities in the immediate vicinity of the plant, particularly at recirculation canal Station X-3, where consistently low densities were observed. The data also indicate, however, that these variations are within the natural variation introduced by river discharge and substrate characteristic fluctuations in the upstream and downstream control areas of the river during 1978. 2.2.3.2 Artificial Substrate Sampling - Taxa Inventory / Seasonal Occurrence Artificial substrate sampling yielded 108 invertebrate taxa, of which chironomid larvae comprised the greatest portion (Table 2.2-5). The most ubiquitous organisms were nema-todes, Na id id ae (Oligochaeta), and the midge larvae, Glypto-tendipes sp., Cricotopus sp., and Tanytarsus sp., Beginning with the May sampling period and extending to the end 2.2-18 2[h }[f
of the year, mayfly nymphs ( S t e n one.rr.a sp. and Caenis sp.) and caddisfly larvae (Hydropsyche orris, Hydropsyche sp., Cheumatopsyche sp., Potamyia sp., and Neureelipsis sp.) were also widespread in the study area. Artificial substrate sampling yielded 56 taxa that were not collected by grab sampling. This number can be compared with 23 and 39 taxa, which were found xclusive to multi-plate samplers in 1977 and 1978, respectityly. The majority of organisms exclusive to the multiplate samplers were immature insect forms representing the orders Ephemeroptera (mayflies), Trichoptera ( cadd is fl ies ) , and Diptera (flies, midges). Numerical Abundance Seasonal density distribtuion data (Figure 2.2-4 sad Table 2.2-6) reflected s im il a r numerical trends to those ob-served in 1976 and 1977 for multiplate sampling in the study area. Peak densities for all stations were recorded during the May to November time frame. Recirculation canal (X-3), intake (X-2), and discharge canal (Y-1) stations displayed the highest densities during 1978 -- a fact consistent with prior years of data (Texas Instruments 1977, 1978; Haynes 1976). Overall, densities ranged from zero values recorded at X-1 and Y-2 in January to 108,921 organisms /m at X-3 in May (Table 2.2-7). High density values were also recorded at X-2 in May (approximately 76,000/m ), X-3 in August (67,352/m 2 ), and Y-1 in September ( 6 2,6 26/m ) . B-1, SL, X-1, and Y-2 generally exhibited higner densities in 1978 than were observ ed in 1977; this was particularly true in the May and September sampling periods. Pet ant Composition The relative abundance of major taxa in the study area is displayed in Figure 2.2-4. January, February, April, and 2.2-19
}
May samples were generally dominated by aquatic oligochaetes ( Na id id ae ) . Nemerteans (?roboscis worms) and nematodes were also present in appreciable numbers during this time period at X-2, X-3, and Y-l. Chironomid larvae began to appear in large numbers in the May sampling period, and was a prevalent group in the July through Novembet collections. Glyptotendipes sp. was the dominant chironomid encountered with densities reaching ma x im um s of 49,462/m 2 at X-3 in August and 52,379/m at Y-1 in September. These values represented 73.4 percent and 83.6 percent, respectively, of the organisms collected at the station during the specified sampling periods. Cricotopus sp., Parachironomus sp., Psectrocladius sp., Polypedilum sp., D_i c rote nd ipe s sp., and Tanytarsus sp. were other chironomids that were commonly encountered and sometimes numerous in the study area from May through November. Trichoptera larvae and/or pupae of the families Hydropsychidae and Polyce n t ropod id ae were also commonly e n ec,u n te red , and were periodically n ume rous in the July to November collections. Hydropsyche orris, Hydropsyche sp., Cheumatopsyche sp., Potamyia sp., Hydro-psychidae (LPIL), Cyrnellus sp., Neureclipsis sp., and Polycentropodidae ( LPIL) , collectively, constituted 10.2 percent, 35.0 percent, 36.6 percent, and 27.8 percent of the total organisms collected in the study area during the July, August, September, and November sampling periods, respec-tively. Na id id ae ( Ol igoch aeta ) were again the most dominant organisms in the area in the November and December collec-t io n periods, with densities representing 46.8 percent and 84.8 percent of the organisms collected during these months, resp ctively. Naidids were e spe cially numerous at X-3 in November, where they comprised 87.2 percent of the total, a figure equivalent to approximately 52,800 organisms /m 2 . As in prior years, Na id id ae , Chironomidae (particularly Glyptotendipes sp. and Tanytarsus sp.), and Hydropsychidae were the predominant organisms collected during 1978. 2.2-2 276 179
Na id id ae dominated the J arm a ry , February, April, and May collections. Chironomids began to increase as a proportion of the total in May and, along with net-spinning caddisflies (Hydropsychidae and Polycentropodidae), constituted the majority of organisms collected during tha warm summer and fall months. While a greater number of taxa were collected during 1978 than in the three previous years, the taxa comprising the dominants for multiplate samplers were very s imilar for all four years, indicating 11 '.tl e or no altera-tion in the compositional characteristics of the community dur.ng 1978. Community Diversity Table 2.2-6 summarizes density, H', J', and number of taxa collected Figure 2.2-5 shows the changes in d iversity (H') occurring through the year for artificial substrate samples. Seasonal variations in diversity (H') were char-acterized by generally higher values during the warmer months of May through November, consistent with the greater numbrrs of taxa collected during this period. Diversity (H') values ranged from O (Staticn SL, Januar" and February; Station X-1, February) to 3.46 Station X-1, November). These values can be compared against the ranges observed in 1977 (0 to 2.78), 1976 (0 to 2.83), and 1975 (0 to 2.78). Generally, higher community diversity measures were recorded during 1978 due to the influx of a number of taxa of drift-type organisms in the artificial substrate collections, a condition brought about by high stream and river discharge rates in the study area. Stetions X-2, X-3, and Y-1 gener-ally d isp1ayed the lowest d ive rs ity (H') measurL in 1978. Evenness (J') ranged from 0 to 0.91 with a mean J' of 0.45 and a standard deviation of 0.25. The lov ' values observed during 1978 reflect toe dominance of certain taxa (i.e., Naididae, Glyptotendipes sp., and Hydropsyche orris) in the study area. 2.2-21 276 180
Statistical Analysis Sampling with the Hester-Dendy Multiplate Sampler was not consistent across the year. There were, however, subsets of months and stations that formed consistent blocks of data. Three such blocks were used to compare stations (Table 2.2-8). The Newman-Keuls multiple range test compared the mean densities against the background sampling variation to determine which s ta t ion ( s ) was statistically distinguish-able. Logarithmically transformed data yielded a test which compared relative orders of magnitude rather than absolute density d if f erence s . This trans fo rmat ion also tended to stabilize variance in the analysis. Data from January, February, April, May, July, August, September, November, and December, and Stations X-1, X-2, X-3, Y-1, and Y-2 show that X-1, Y-2, Y-1, and X-2 had statistically s im ilar densities. This was also true with samples from intake forebay (X-2), recirculation canal (X-3), and discharge (Y-1). Transformed data showed that X-1 and Y-2 had s im ila r densities, and that these two stations were significantly different from X-2, X-3, and Y-1. Adding Sturgeon Lake (SL) to the analyses showed that SL sample density was most similar to Station X-1, the nearest other test station, and to Y-2. Transformed data showed that SL density was 7tistically identical to X-1 and Y-2 density measurements Data for all stations for May, July, August, and November showed the recirculation canal (X-3) to have significantly higher densities than all other tested stations. The remaining stations were not distinguishable from each other 2.2-22
on the basis of total density. Logarithmically trans fo rmed data indicated that X-3 and X-2 were similar and that these stations were significantly dif ferent from 3L, B-1, and X-1. Stations Y-1 and Y-2 were statistically similar to one another and both were similar to X-2, X-3, and B-1. Station Y-2 was signficantly dif ferent from X-3. In summary, in 1978 as in 1977, stations near the plant were readily distinguishable f rom the more distant stations. The upstream and downstream control stations, Sturgeon Lake, and intake station (X-1) were also similar to one another, particularly SL, B-1, and X-1. Data indicate that effects of power plant ope rat io n on benthic organis- densities (as reflected on Hester-Dendy mult ipl ate samplers) is l imited to the immediate vicinity of the Prairie Island Nuclear Generating Plant, particularly with respect to the recir-culation and/or discharge of heated water. 2.2.4 DISCUSSION In order to assess the influence of operations of the Prairie Island generating facility on the benthic macro-invertebrate community, it is first necessary to describe natural community dynamics and their pertinent control factors in the study area. During 1978, high r iv e r dis-charge with its attendant effects of biota / substrate scour and rapid -- sometimes turbulent -- current, played a major role in influencing community dynamics. These etfects were noticeable bot:1 in the infaunal and artificial substrate sample results. Infaunal effects were most readily observed in the upstream control (B-1) and downstream control (C-1 and C-4) stations, where densities of benthic organisms were markedly reduced from March through November when compared with 'evels reached at these stations during 1976 and 1977 (Texas Instruments 1977, 1978). The scouring effects of unusually high discharge rates on infaunal 2.2-23
community dynamics, as experienced in the study area during the first three quarters of 1978, are well documented (Hynes 1970; Hoopes 1974; Anderson and Lehmkuhl 1967). The resi-liency of the infaunal community at the control stations was observed in the g rad ual upward trend in densities during October and November after flow rates had s ub s id ed . High flow rates had several positive ef fects on epif aunal (drift) organisms colonizing the Hester-Dendy multiplate samplers. First, swift currents provided favorable conditions for the e s ta bl ishment of large popul a t ions of case-building, net-spinning midge (i.e., Tanytarsus sp.) and caddisfly larvae (i.e., Hydropsyche orris) that rely on water flow to satisfy their filter-feeding requirements. Second, the heavy rainfall that led to high discharge rates in the June to September period undoubtedly caused dislodging and drift of organisms from the tributary streams and littoral areas of the river. The enrichiucnt of the taxa list for artificial substrate samplers, 31 additional taxa, when compared with 1977, is indicative of the magnitude of this e f fect. It can also be noted that community diversity levels, as measured by H', are generally observed to be higher in 1978 than in 1977 due largely to the influx of new taxa in the drift. Just as Station B-1 was impacted unfavorably by the scouring effects on the infauna, it generally reflected the largest increases in epifaunal densities, relative to 1977, with increased flow r a t e t, . These natural variaticas in benthic community dynamics observed during 1978 can be consolidated with community structure information that has remained similar from 1976 through 1978 to serve as background against which plant operation effects can be evaluated. As in 1976 and 1977, t ub i f ic id s and chironomids dominated the infaunal collections, and na id id s , chironomids, hydro-psychids, and polycentropodids dominated the epifaunal (drift) collections. Also, as in prior years, seasonal 2.2-24
temperature variations were important determinants on com-munitir structure in that immature insect forms, especially midge and caddisily larvae, displayed greatest abundance in the epifaunal drift community during the warmer months of the year. Generally, the gross community structure charac-teristics d escr ibed in the 1976 and 1977 s tud ies are sup-ported, by, and similar to, 1978 data. The high flow rates observed in the river during 1978 significantly altered substrate stability at the upstream control (B-1) and down-stream control (C-1 and C-4) stations and prevented benthic organisms from becoming established. This natural situation is similar to the man-induced conditions at X-3 in the recirculation canal. Moderate to swift discharge currents le ad ing to substrate instability and t hermal enrichment at X-3 combine to create an unfavorable environment for benthic invertebrates. Statistical analysis of the infaunal results confirms that X-3 B-1, C-1, and C-4 were similar (a = 0.05) in 1978. The fact that Y-2 at the and of the discharge canal, and SL, the upstream control are similar may suggest that plant effects are confined to the immediate vicinity of the plant for infaunal populations, and that recovery is evident by the outlet of the discharge canal at Station Y-2. The data also suggest that the variation introduced by a significant natural event, such as unusually high discharge rates in the main river channel, produces effects that are similar to the conditions observed in the stations most heavily influenced by plant operation (X-2, X-a, Y-1) for both infaunal and epifaunal community components. As in past years, it appears that the current study design is adequt te to segregate and characterize natural population fluctuations and plant ef fects, both temporally and spa-tially, wi r.n in the study area. The large impact of high stream flows on the upstream and downstream contro) stations during 1978 makes it difficult to determine if plant-induced effects are sustained in the downstream infaunal benthic 276 184 ' 2.2-25
community. Percentage composition data similar to 1977 for C-1 and C-4 and the similarity of the discharge station (Y-2) to upstream ccatrol station (SL) seem to indicate that pl an t-i nd uced ef fects are not sustained downstream. Epi-faunal results ind ic ate that sim ilar effects on community dynamics are introduced by high discharge rates in the river I by plant ope rat io nal effects, although epifaunal densi-
.es were generally significantly (a = 0.05) higher in the immediate vicinity (i.e., Stations X-2, X-3, Y-1) of the plant.
2.2.5
SUMMARY
- 1. Dominant taxa observed during 1978 in the vicinity of the Prairie Island Nuclear Generating Plant were Tubificidae ( Oligoch aeta ) and Chironomidae (Diptera) in the infaunal collections and Naididae (Oligochaeta),
Chironomidae, Hydropsychidae, and Polycentropodidae (Trichoptera) in the epifaunal collections.
- 2. Unusually high spring and summer discharge rates in the main river channel had major impacts on the abundance of infaunal organisms and the abundance and composition of epifaunal org anisms. These effects were most noticeable at B-1, C-1, and C-4, where high flow rates scoured the infaunal populations but contributed to increased colonization of the rig id Hester-Dendy substrates by filter-feeding taxa and drif t organisms.
- 3. As in the time period 1975-1977, data suggest that stations closest to the plant, and particularly in the intake forebays (X-2) and recirculation canal (X-3),
were different from other stations. The outstanding exception to this generalization is observed in the infaunal comparisons where X-3 is statisticully similar to t he main river s tations ( B-2, C-1, C-4) that had been 2.2-26
subjected to the natural scouring effects of high river discharge.
- 4. Although the denud ing of downstream control stations (C-1 and C-4) makes it difficult to assess the impact of plant operational effects on downstream community characteristics, it appears that the relative stability of infaunal collections at Y-2 from year to year for infaunal and epifaunal community components and their similarity to upstream control (SL) during 1978 are indicative of localization of plant effects to the immediate vicinity of the f acility.
- 5. Gross community characteristics (i.e., total densities and relative abundance of dominant taxa) described in this report are generally s im ilar to those presented in the 1975-1977 annual reports, indicating little overall change in the main constituents of the benthic macro-invertebrate community from year to year.
