SPRING 1979 QUARTERLY REPORT BAILLY NUCLEAR-1 SITE ENCOMPASSING APRIL-JUNE 1979 15 August 1979 Prepared for NORTHERN INDIANA PUBLIC SERVICE COMPANY 5265 Hohman Avenue Hammond, Indiana 46325 Prepared by TEXAS INSTRUMENTS INCORPORATED Ecological Services P.0 Box 225621 M/S 3949 Dallas, Texas 75265 827 161 science services division

o FOREWORD Ecological Services of Texas Instruments Incorporated, under contract to Northern Indiana Public Service Company, is conducting an ecological moni-toring program to determine and document existing ecological conditions in the immediate vicinity of the Bailly Nuclear-1 Generating Station site, Baillytcwn, Indiana. This ecological monitoring program will provide data necessary for assessing and minimizing the effects of plant construction on the local environment and will provide information for assessing any future changes.

This report, the 20th in a series of quarterly reports prepared for Northern Indiana Public Service Company by Texas Instruments, contains analyses and interpretation of data for April through June 1979. No collection of aquatics data was scheduled during May 1979 or of terrestrial during April or June 1979. Statements contained in this report are based on data collected over a relatively short time period and should be viewed as preliminary.

SUMMARY

Terrestrial Spring 1979 terrestrial sampling on the Bailly Study Area was accomplished on schedule during two periods in May. Sampling counts included:

e Sherman live-trapping of small mammals e Observations of large mammals e Roadside counts of cottontail rabbits and birds e Transect counts of birds e Surveys of reptiles and amphibians e Collection of soil samples e Inspection of vegetation for foliar damage Mammal sampling revealed 14 species; three species were trapped, while 11 were either sighted or their tracks or other signs observed. Small-mammal populations appeared to be low, as might be expected following a severe winter such as 1978-79. Few individuals were trapped; chipmunks and tree squirrels seemed to be less active or less abundant than usual in forested habitats. Only five cottontail rabbits were observed along the road route -

the fewest recorded during this monitoring study.

There were 92 species of birds observed on and in the vicinity of the Bailly Study Area. During the first sampling period, primarily early migrants were sighted; this included frequent sightings of the Common Merganser, Caspian Gull, Yellow-rumped Warbler, and White-throated Sparrow. Surveys during the second sampling period produced higher counts of species that typically reside on the Bailly Study Area during summer months; these included the Common Yellowthroat, American Redstart, and Rose-breasted Grosbeak.

Although cold wet weather ' undoubtedly limited amphibian and reptile activity in general, several large choruses of gray treefrogs were heard. Of the nine herpetile species recorded, the painted turtle was the only one frequent ly sighted.

o Aquatic Spring 1979 aquatic sampling was accomplished in April and early May. Phyto-plankton, periphyton, zooplankton, benthos, fisheries, and water quality samples were collected. This report does not include results of the chloro-phyll a, benthos, fisheries, and pond sediment analyses for any of the June data. These analyses will be included in the summer 1979 quarterly report.

Lake Michigan and interdunal pond phytoplankton densities were higher in April 1979 than in April 1978 but lower than in November 1978. In the lake, blue greens and diatoms dominated density, while diatoms dominated biovolume; there were nine dominant taxa (4 percent or greater) among a total 53. In the ponds, density increased approximately 3-fold from November 1978, blue-greens were density-dominant, diatoms were biovolume-dominant, and there were five dominant taxa among a total of 50. No unusual or undesirable taxa were found in either the lake or the ponds. April 1979 productivity results for Lake Michigan were similar to those of November 1978, and no unusual values were observed during either quarter. Pond productivity values were much lower in April 1979 than in April and November 1978. The 1979 productivity results indicated no adverse effects due to plant construction.

Periphyton data for April 1979 showed that blue green algae, comprised mostly o f Lyngbva spp. , dominated both Lake Michigan and pond samples. Blue greens and diatoms were co-dominant contributors to lake biovc,lume , while diatoms were dominant and greens subdominant in the ponds. Lyngbva spp. did not contribute significantly to the total pond biovolume. In Lake Michigan, periphyton densities were lowest at station 25 and highest at station 12.

Average lake densities exhibited a 6-fold decrease from November 1978 to April 1979. Pond densities showed only a slight decrease from November to April; however, compared with April 1978, a 2.5-fold decrease in density was observed. Low water temperatures (approximately 5.ci at time of sampling) are suspected as the cause of the slow spring periphyton growth. Periphyton diatom data indicated that Fragilaria vaucheria represented as much as 69 percent of the diatom assemblage of the lake and that Achnanthes minutissima, Fragilaria crotonensis, and Gomphonema angustatum dominated pond samples.

O s

April 1979 zooplankton densities averaged 1,211 organisms per cubic meter in Lake Michigan and 20,090 organisms per cubic meter in the interdunal ponds.

A ' atal of 42 taxa were observed in Lake Michigan and 33 taxa in the inter-dunal ponds. Nearfield lake densities continued to be higher than farfield densities. The lake zooplankton communi:.y exhibit ed no obvious changes in composition in April 1979. Cowles Bog exhibited the highest density (49,958 organisms per cubic meter); ponds B and C were much lower (3,687 and 6,625 organisms per cubic meter, respectively). Cladocerans dominated ponds B and C, while copepods dominated Cowles Bog. No unusual taxa or density changes were noted in either the interdunal ponds or Lake Michigan.

Ichthyoplankton catches yielded rainbow smelt and unidentified eggs as well as rainbow smelt yolk-sac larvae. The only previous year in which catches had been productive in April was 1975. The cool lake temperatures appear to have promoted some degree of smelt spawning in the lake.

Water quality parameters were measured in both Lake Michigan and the inter-dunal ponds. All values were within acceptable ranges for protection of the indigenous population. Although some parameter values exceeded Indiana standards, particularly those of ammonia and nitrate, which could stimulate growth of phytoplankton, there was no indication of stimulated growth. The general water quality parameters continued to indicate high water quality in Lake Michigan and generally in the ponds. The aquatic nutrients at times exceeded the Indiana standards but nad no effect on the flora or fauna.

Indicators of industrial contamination and trace elements changed little from previous sampling periods.

Species checklists for May 1979 appear in Tables 1.3 (mammals), 1.6 (birds), and 1.11 (herpetofauna).

1.3 RESULTS AND DISCUSSION 1.3.1 MAMMALS. During May 1979, 14 mammal species were captured or observed on the Bailly Study Area (Table 1.3). As in 1977-78, severe winter weather apparently affected small-mammal population levels: only three species and few individuals were trapped, and there were comparatively few observations of chipmunks and tree squirrels (Table 1.4). jJ}

o 1.3.1.1 Beachgrass Community. The masked shrew (Sorex cinereus) was the only :nammal captured in the beachgrass community during May 1979 (Table 1.4). One individual was captured on two occasions at different stations along the 50-trap transect in this locale.

Tracks of the raccoon (Procyon lotor) and white-tailed deer (Odocoileus virginianus) were observed throughout the community (Table 1.5).

1.3.1.2 Foredune. As usual, the same larger-mammal species observed in the beachgrass community occurred in the foredune area (Table 1.5). Theee species generally cross both areas en route to the Lake Michigan shore.

1.3.1.3 Immature Oak Forest. No small mammals were captured in this location during May 1979. Midway through the second sampling period, 22 traps were stolen from the transect. Calculations for this transect were based on 278 trap sets. Except for one red squirrel (Tamiasciurus hudson-icus), mammals recorded were the same as those in the other lakefront loca-tions.

82./ 174 1.4 science services division

o 1.3.1.4 Cowles Bog (Wooded). The white-footed mouse (Peromyscus leucopus) was the only mammal trapped in the wooded bog during May 1979 (Table 1.4). All captures occurred in the wet woods.

Six other mammal species were sigbted in this locale (Table 1.5). Raccoons appeared quite active along the trail, but the eastern chipmunk (Tamias striatus) seemed to be less active than usual. Also, the fox squirrel (Sciurus niger) appeared somewhat less abundant than in past springs. One white-tailed deer was sighted.

1.3.1.5 Cowles Bog (0 pen). A white-tailed deer was one of six species recorded from the dike that parallels the open bog (Table 1.5). This mature doe was probably the same one observed in the wooded bog just off the trail.

Tracks observed in this and other locations indicated that at least two other deer utilize the Bailly Study Area extensively.

1.3.1.6 Maple Forest. Four white-footed mice were captured along the trapline in this locale (Table 1.4). The red squirrel was the only other species sighted (Table 1.5), although the tracks of raccoon and white-tailed deer were noted.

1.3.1.7 Emergent Macrophyte. Three species of mammals were sighted in the macrophyte sampling location during May 1979 (Table 1.5). On one occasion, four fox squirrels feeding on willow along the pond's shoreline were observed. The muskrat (Ondatra zibethica) and raccoon are fairly common in this location. although muskrat sightings have become less frequent during the past 2 years.

1.3.1.8 Transmission Corridor. One short-tailed shrew (Blarina brevicauda) was captured along the transmission assessment line (Table 1.4).

Trcpping results possibly were affected by an early May fire that burned approximately half of the trapping area. The raccoon was one of three larger-mammal species for which signs were observed in this location during May 1979 (Table 1.5). c 8,2./ 1 ,/ 3 1.5 science services division

o 1.3.1.9 Industrial Areas. A 13-lined ground squirrel (Spermophilis tridecemlineatus) was sighted in lawn habitat in this location during May jip i: 1 (Table 1.5).

1.3.1.10 Road Route. The 22-mile road route survey produced sightings of only five eastern cottontail rabbits (Sylvilagus floridanus) during May 1979. Tlis represented the fewest sightings during the 6-year survey period; the number of sightings per survey has ranged fr7m 5 to 34 and has averaged about 15. The previous low number was 7 in May and July 1978.

1.3.2 BIRDS. The spring 1979 bird surveys in the Bailly Stud; Area produced 92 species; these are listed, along with their probable status, in Table 1.6. In Table 1.7 are data collected along transects in six of the major sampling locations, in Table 1.8 data from the transects along Cowles Bog trail, in Table 1.9 the aquatic survey data, and in Table 1.10 the road route data.

1.3.2.1 Beachgrass Community. One Barn Swallow (Hirundo custica) .:s s sighted on each 375-foot transect in this community (Table 1.7). Tree Swallows (Iridoprocne bicolor) and Bank Swallows (Riparia riparia) feeding on insects flying over the beachgrass were observed during nonsurvey periods. _ _

1.3.2.2 Immature Oak Forest. The two transects in this locale during May yielded four species of birds (Table 1.7). The Yellow-rumped Warbler (Dendroica coronata), generally one of the first warblers to migrate north during spring, was sighted most frequently (three observations per survey).

1.3.2.3 Cowles Bog (Wooded). There were one to two sightings of six bird species along the two transects in the wooded bog. The Gray Catbird (Dumetella carolinensis) and American Robin (Turdus migratorius) were the only species sighted on both transects.

• See Figure 1.2 1.3.2.4 Cowles Bog Trail. During the first sampling period in May 1979, vireos and warblers had not arrived in this location; by the third week in May, when this bird survey was conducted, however, most of the vireos and warblers had arrived in the wooded bog along with several other species.

Three warblers, Common Yc!1owthroat (Geothylypis trichas), Wilson's Warbler (Wilsonia pusilla), and American Redstart (Setophaga ruticilla), were especially common (Table 1.8). Transects 8 and 4 yielded the most species -

11 and 8, respectively.

1.3.2.5 Cowles Bog (0 pen). Five species of birds were observed in the open bog during May transect counts. The Tree Swallow and Red winged Black-bird (Agelaius phoeniceus) were the only species common to both transects.

O 1.3.2.6 Maple Forest. The American Robin, one of four species observed in this location during May 1979, was the only species observed on both transects. Three White-thicoated Sparrows were si, hted near the end of transect B.

1.3.2.7 Transmission Corridor. No birds were sighted along transects in the transmission corridor during May 1979. Most of the area along the transects had been disturbed recently: herbicides and cutting during 1978 reduced shrub /forb cover in the location, while fire during early May 1979 burned approximately one-half of the sampling location, further diminishing the area's vegetation. These events undoubtedly contributed to bird avoid-ance of this location.

1.3.2.8 Aquatic Habitats. Aquatic locations A through J (Figure 1.2) were surveyed on several occasions during May to determine maximum bird use.

The total species count for all areas was 20 (Table 1.9). The outf all area (J) yielded the most species (10) and individuals (293). The Ring-billed Gull (Larus delawarensis) was the dominant species. A group of eight Caspian Terns (Hydroprogne caspia), a species that has not been reported in the Bailly Study Area since October 1975, was sighted at location J during the first week in May. Several sightings of Canada Goose (Branta canadensis) occurred during May 1979; some of the geese apparently were trying to nest on pond E. A flight of 10 Common Mergansers was using pond D during the first week of May but, by the third weck of May, apparently had moved farther north, prc.,mably to breeding grounds in Canada.

1.3.2.9 Road-Route Census. The survey of the 22-mile road route (Figure 1.3) in the early morning hours during the third week of May yielded 40 species. The most frequent species was the American Robin, which occurred at 11 stops; second most frequent was the Blue Jay (Cyanocitta cristata),

which occurred at 10 of the 22 stops. The Ring-billed Guli was the most numerous species sighted: 212 individuals were observed at stop 22. Other commonly sighted species included the Herring Gull (Larus argentatus) and the Red-winged Blackbird.

O 1.3.3 AMPHIBIANS AND REPTILES. Herpetile activity undoubtedly was affected by the unusual cold as well as by the wetter conditions during May 1979 (compared with previous years); low temperatures inhibited reptile activity, while increased water promoted frog activity. Nine species of amphibians and reptiles were noted during the two survey periods (Tables 1.11 and 1.12).

o 1.3.3.1 Lakefront Communities (Beachgrass-Foredune-Immature Oak). No reptiles or amphibians were observed in the lakefront communities during May 1979. Weather conditions prob 2ly contributed to these results; however, few herpetiles have becc. sighted in these communities in the past.

1.3.3.2 Cowles Bog (Wooded). Frogs were f airly active in the wooded Dog during May 1979 (Table 1.12), with large choruses (approximately 25 individuals) of gray treefrogs (Hvla versicolor) calling from several loca-tions in the bog. Scattered small choruses (approximately 10 individuals) of wood frogs (Rana sylvatica), as well as an occasional green frog chorus (Rana clamitans), were also noted.

1.3.3.3 Cowles Bog (0 pen). Frogs of several species were common in this location during May 1979 (Table 1.12). Of particular importance were cricket frogs (Acris crepitans), which were heard throughout the open bog as were spring peepers (Hyla crucifer).

1.3.3.4 Maple Forest. The maple forest, like other s ampling loca-tions, was unusually wet during May 1979 and contained pools cf water through-out. The only herpetile observed was the wood frog. This first sighting of the wood frog in this location likely was correlated with the wet conditions.

1.3.3.5 Emergent Macrophyte. Six species of herpetiles were observed in the macrophyte community during May 1979 (Table 1.12). Two adult male bullfrogs (Rana catesbeiana) calling from the shoreline were observed, and choruses of three other frog species were noted, including one large gray treefrog chorus (approximately 50 individuals). Numerous painted turtles (Chrysemys picta) basking on logs in the aquatic macrophyte community were observed, and two sunning northern water snakes (Natrix sipedon) were observed. Water snakes were generally less active during May 1979 than during past springs.

827 185 1.3.3.6 Transmission Corridor. Small choruses of cricket frogs and spring peepers were heard calling from small temporary pools of water in this locale during May 1979. A wounded common garter snake (Thamnophis sirtalis) 1.15 science services division

o was found along a burned section of the corridor, apparently having been stunned by the fire and attacked by birds or shrews, which had eaten most of its head.

1.3.4 FOLIAR DAMAGE. Older needles on white pine (Pinus strobus) along the Bail.ly entrance road still exhibited some flagging. New needles had not yet formed, nor had deciduous trees leafed.

1.3.5 SOIL CONDUCTIVITY. All soil samples for conductivity analysis were collected during May 1979, and results of the soils analysis will appear in the summer report.

@2.2 AQUATIC FLORA 2.2.1 METHODOLOGY. Duplicate 2-liter phytoplankton samples were collected with a 6-liter Van Dorn bottle at stations 1 through 10 in Lake Michigan and at stations 17 through 21 in the pond areas (Figure 2.1). All samples were collected from 1 meter belos the surface. Before sampling, each 2-liter sample container was prepared with 20 milliliters of acid Lugol's so lution, which is a narcotizing settling agent. After sampling, each container was supplemented with buf fered formalin to a final concentration of 4 percent and 3 to 5 drops of liquid detergent to facilitate sedimentation.

Before processing, each sample was allowed to settle for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />; then 1800 milliliters of supernatant were siphoned off with a membrane-covered siphon.

The remaining 200 milliliters were apun on a laboratory centrifuge at 2000 revolutions per minute for 15 minutes to further concentrate the organisms before the supernatant was filtered off the centrifuge tubes and the " bead" of phytoplankton transferred to 12-dram vials.

In the laboratory, concentrated phytoplankton samples (10 milliliters) were thorought, mixed and three cubsamples placed in Palmer cells. The algae in 12 fields ( four per subsample) were identified, enumerated, and measured at 400X magnification. In instances where there was a scarcity of organisms in a sample, the total field count was extended to 24 fields. Biovolume (micro-liters per liter) was determined by attributing to the algae geometric shapes best suiting their morphology and calculating their appropriate volumes (Nauwerck 1963; Rodhe, Vollenweider, and Nauwerck 1958; Strickland 1960).

Instead of developing an average volume per species based on a few representa-tives, dimensions of each organism enumerated were measured.

Phytoplankton productivity samples were taken at the same locations and sampling frequency used for collections for identification, enumeration, and biovolume measurements. Duplicate samples were collected from 1 meter below the surface at each station in a 6-liter Van Dorn bottle. Each collected sample was strained through a 333-micrometer mesh nitex net to remove zoo-plankters and large detrital material that could be labeled by the carbon-14 material.

827 189 science services division 2.3

o The strained water of each sample was measured in a 2-liter flask to which three 1-milliliter aliquots of 5-microcuries NaH C03 were added and thor-oughly mixed. A time-zero sample consisting of two 0.5-milliliter subsamples was measured and placed in scintillation vials along with one drop of 6N sodium hydroxidc. Two 50-milliliter subsamples also were removed and strained through Whatman GF/C filters at minimum vacuum pressure (less than 50 millime ters Hg differential across the filter) and the filters placed in scintillation vials. Duplicate clear and darkened 300-millili ter BOD bottles were filled with the remaining sample. After all samples had been prepared, they were suspended 1 meter below the surface at their stations for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

Following incubation, the bottles were retrieved and the contents of each pre-served by adding 12 milliliters of buf fered formalin. Subsamples of 50 milli-liters were removed from each bottle and filtered as previously described; each was p aced in a labeled scintillation vial with enough tissue solu-bilizer to cover the filter pad. Activity counts were mada with a liquid scintillation counter.

The following formula (APHA 1971) was used to calculate from the scintilla-tion counts the phytoplankton productivity in milligrams of carbon fixed per liter for each replicate sample:

mg carbon fixed /f/4-hr period = (counting rate /cotal activity) x (total sample volume /subsample volume) x mg/l initial organic carbon (mg/f) x 1.064 where Total activity = amount of potentially available carbon-14 at time zero Counting rate = clear bottle counts minus darkened bottle counts Total sample = 300 milliliters volume Subsample volume = 50 milliliters 1.064 = correction for isotope ef fect 827 190 Phytoplankton chlorophyll a, samples were collected from the same water samples from which regular phytoplankton s amples were extracted (stations 1 2.4 science services division

O through 10 and 17 through 21) . To prepare phytoplankton samples for chloro-phyll a_ analysis , a measured volume of water was filtered through a 0.45-micrometer filter pad stabilized with magnesium carbonate. The filter pad war then frozen for shipment to the central laboratory, where it was extrac t.-

ed for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> with acetone, ground for 30 seconds with a tissue grinder, centrifuged, and measured on a narrow-band spectrophotometer at 665- and 750-millimicron wavelengths before and after sample acidification. Periphyton samples were similarly processed using measured scrapings from natural (as available) or artificial substrates. All concentrations were calculated using the following equation (Vollenweider 1974):

Chlorophyll a (mg per sample) = (Db -D,) [R/(R-1)] (V/1) (10 /ac )

= 11.9 x 2.43 (Db -D,) (V/1) where D, = optical , density of sample af ter acidification - D665 -D 750 (acidified)

D Ptical density of sample before acidification = D -D 665 750 b " (unacidified) a = specific absorption coefficient for chlorophyll a (in grams per centimeter)

V = volume of solvent used to extract the sample (milliliters) 1 = path length in centimeters R=D!a b f r Pure chlorophyll a,= 84 (Talling and Driver 1963)

To convert to micrograms per liter or micrograms per square centimeter, the chlorophyll a, value was divided by number of liters filtered or number of square centimeters scraped.

Periphyton sampling was scheduled at five Lake Michigan stations (1, 10, 11, 12, and 25) and three pond stations (17, 19, and 21). Pond samples were collected using a Design Alliance periphytometer, a modification of a samplir first described by Patrick, Hohn, and Wallace (1954). This sampler suspende one rack of eight glass slides, with a surface area of 37.5 square centi-meters per slide, just below the surface as a substrate for periphyton colonization. Colonization generally occurs in 2 to 4 weeks; thus, the 2.5 82 }/ } 9 ) science norvices division

" incubation" time per sampler is 1 month. Lake samples were scraped from stural substrates (as available) at each sampling station. The slides (both sides) and substrate scrapings were placed in 8-dram vials and preserved with 6-3-1 solution (six parts water: three parts ethanol: one part formalin).

Two replicate slides per sample were quantitatively analyzed; however, all slides were scraped and the scrapings saved for references. Counts were made as described for the regular phytoplankton samples. Biovolume estimates were also generated in a manner fashioned after the phytoplankton biovolume tech-nique.

2.2.2 PHYTOPLANKTON RESULTS AND DISCUSSION 2.2.2.1 Identification and Enumeration. Average phytoplankton densities during April 1979 were: Lake Michigan, 8095 i 1035 cells per milli-liter; interdunal ponds, 8469 1 2324 (Table 2.3 and Appendix A). Biovolume averaged 7.90 1.12 microliters per liter for Lake Michigan and 6.15 2.75 microliters per liter for the ponds (Table 2.4 and Appendix B). In both the lake and the ponds, April phytoplankton densities were higher in 1979 than in 1978. Biovolume values were similar to those of April 1978.

Dominant taxa in Lake Michigan (those representing more than or as much as 4 percent of either uensity or biovolume) included Microcystis sp., Aphanizo-menon flos-aquae, Asterionella formosa, Fragilaria sp. Fragilaria crotonensis (density- and biovolume-dominant), Melosira sp., Synedra sp., Nitzschia sp.,

and Tabellaria flocculosa. The diatom taxa were the largest contributors to the biovolume estimates, comprising 92 percent of the total, while density estimates revealed the blue-green algae and diatoms to be equally dominant.

Lake Michigan samples yielded 58 taxa. Diversity (H') and evenness (J') for phytoplankton density were moderate (2.68 and 0.69, respectively), and calcu-lations for biovolume were similar (2.77 and 0.72, respectively).

Samples collected from the interdunal ponds were dominated (more than or as much as 4 percent of the density or biovolume) by Achnanthes sp., Gomphonema sp., Synedra sp., Scenedesmus quadricauda (density-dominant), Cryptomonas ovata, and unidentified members of the Chroococcoceae (blue greens) and Pennales (pennate diatoms). Blue green algae were density-dominant, while 827 192 2.6 science services division

There were 50 taxa during April 1979 in the interdunal ponds. Ponds B and C exhibited higher densities than the Cowles Bog area. The diversity and evenness indexes for density were moderate (2.31 and 0.66, respectively), and were similar to the b io .rolurae indexes (2.30 and 0.65, respectively).

The nearfield stations (1 through 3) have slightly higher densities and bio-volumes than the other areas. Densities differences among sampling areas (Table 2.5) were smaller than those observed during November 1978 (TI, 1979). ~

Density and biovolume were higher in the discharge area than in the other areas. Previous results had indicated that the high discharge values are probably a result of natural variability rather than influence by thermal stimelation. 7 2.9 science services division

@Within the interdunal ponds, density, biovolume, diversity, and number of taxa were quite variable in April 1979, as detailed in Table 2.6 Table 2.6 Phytoplankton Density and Biovolume at Interdunal Pond Stations in Bailly Study Area, April 1979 Density Diversity Biovolume Diversity No. of Station Taxa No./ml H' J' pl/l H' J' 17 18 12,543 1.82 0.48 2.45 2.48 0.76 18 23 8,464 2.42 0.65 1.79 2.89 0.78 Pond B (17-18) 29 10,503 2.12 0.57 2.12 2.12 0.77 19 24 15,265 2.63 0.71 19.29 1.69 0.46 20 17 6,881 1.58 0.46 3.55 2.09 0.60 Pond C (19-20) 33 11,073 2.11 0.58 11.42 1.89 0.53 Cowles Bog (21) 14 3,831 2.69 0.81 4.92 2.15 0.65 All pond 50 8,469 2.31 0.66 6.15 2.30 0.65 Density (3831 cells per milliliter) and number of taxa (14) were lowest in Cowles Bog; however, biovolume in Cowles Bog was not lowest because of the presence of Gomphonema sp., a large diatom, which comprised 44 percent of the biovolume. Station 19 (pond C) represented the highest density (15,265 cells per milliliter) and biovolume (19.29 microliters per liter). Mean density from all ponds represented a 2.5-fold increase, and mean biovolume a 6-fold increase over November 1978. The blue greens and diatoms were numerically dominant, and the diatoms dominated biovolume estimates. These results are typical of spring growth in small water bodies such as the interdunal ponds.

Diversity and evenness values exhibited no change from November 1978.

Data from both the lake and the ponds were examined for taxa considered either unusual or undesirable. Although large numbers of Oscillatoria spp.

(a blue-green alga) were found in the ponds, densities were not high enough to create an odor problem and no unusual taxa were found. None of the phytoplankton data indicated any effects of plant activities.

o 2.2.2.2 Productivity. Productivity levels (milligrams carbon fixed per liter per 4-hour incubation period) at the 15 phytoplankton sampling stations are presented in Table 2.7. Lake Michigan values ranged from 0.738 mg C/1/4 hr to 11.795 mg C/1/4 hr (negative values excluded), with a mean of 3.288 mg C/f/4 hr. Pond mean results were lower, ranging from -0.065 (pond C) to 0.813 (pond B) to 5.159 mg C/f /4 hr ( Cowle s Bog). The overall pond mean value was 1.664 mg C/f/4 hr, which was approximately half that of the lake. A comparison of mean lake values of April 1978 and April 1979 showed 1979 to be 9-fold higher than 1978. The differences probably can be attrib-uted to the variability of the productivity studies. Pond means fluctuated only slightly from April 1978 to April 1979. The results in 1979 indicated no adverse effects due to plant construction.

o 2.2.3 PERIPHYTON RESULTS AND DISCUSSION 2.2.3.1 Density and Biovolume. Lake Michigan periphyton densities 6

during April 1979 averaged 1.239 x 10 cells per square centimeter (Table 2.8 and Appendix C); biovolume averaged 0.04 microliters per square centimeter (Table 2.9 and Appendix D) . Average densities were lower in the ponds (5.743 5

x 10 cells per square centimeter) than in the lake; however, biovolume was 0.19 microliter per square centimeter because of the biovolume contribution of the pennate diatoms.

Lyngbya spp., a blue-green alga, numerically dominated both the Lake Michigan and pond periphyton, comprising 86 percent and 58 percent, respectively.

Lake Michigan biovolume dominance was shared by the blue-greens (52 percent) and the diatoms (48 percent), and Lyngbya spp. made up 23 percent of the total. The mean biovol'ce in the ponds showed a slightly dif ferent dominance pattern consisting of diatoms (75 percent) and green algae (23 percent).

Lygnbya spp. did not contribute significantly to the total pond biovolume.

Dominant taxa in Lake Michigan (more than 4 percent of either tha density or biovolume) included Oscillatoria sp., Lyngbya sp., Schizothrix sp., Diatoma tenue, Fragilaria crotonensis, F. vaucheriae, and Comphonema sp. Dominant pond taxa (using the same criteria) included Lyngbya sp., Oocystis borgei, Oedogonium sp., Mougeotia sp., Fragilaria sp., Synedra ulna, Tabellaria flocculosa, Achnanthes minutissima, and Gomohonema sp. The dominants repre-sented blue-green and green algae as well as diatoms. Lyngbya sp. was tae numerically dominant form in both the lake a id ponds, while the biovolume dominants were Lyngbya sp. (lake) and Gomphonema sp. (ponds).

Periphyton densities , howe 4 station 25 to be lowest and station 12 to be highest; it is not known why stations 1 and 25 were low. Pond B and Cowles Bcg had similar periphyton densities; Pond C density was high primarily because Lyngbya sp. we present in large numbers. Lake periphyton densities were similar from April to April. Pond densities exhibited a 2.5-fold de-crease from 1978 to 1979.

O stations, but few were observed in the ponds. Dominant pennate diatoms in the interdunal ponds were Achnanthes minutissima, Fragilarg crotonensis, and Gomphonema angustatum; they dominated the ponds during April 1978, appearing to be indicators of the ponds' calmer, more nutrient-rich waters.

Within the interdunal ponds (stations 17, 19, and 21) were different groups of taxa by pond. The dominant taxa (more than or as much as 4 percent mean relative abundance) were as follows:

Pond B Pond C Cowles Bog Achnanthes minutissima Achnanthes minutissima Fragilaria vaucheria Fragilaria croton0 sis Fragilaria crotonensis Gomphonema angustatum Fragilaria vaucheria Tabellaria flocculosa Meridion circulare Synedra ulna Synedra fasciculata Tabellaria flocculosa Synedra ulna As indicated, no dominant taxa were shared by all three ponds. Pond B yielded 24 diatom taxa, pond C 32, and Cowles Bog 12. Pond C exhibited the most taxa; the few dominant forms indicated good distribution of diatom taxa.

Density estimates from whole periphyton (Table 2.6) showed that pond C also had the highest density, while Cowles Bog had the lowest density and the fewest taxa. Density estimates support the diatom counts. Achnanthes minu-tissima dominated both density estimates and diatom counts for ponds B and C.

2.2.3.2 Periphyton Chlorophyll a. Results of chlorophyll a analyses will be presented in the summer 1979 quarterly report.

2.3 ZOOPLANKTON 2.3.1 METHODOLOGY. Zooplankton samples were collected in Lake Michigan and the nearshore interdunal ponds. At each lake station (1 through 10), four samples were collected by bottom-to-surface vertical tows of an 80-micrometer mesh, 0.5-meter-diameter plankton net. Each sample comprised a 827 206 2.20 science services division

o composite of four such tows condensed into one 1-liter sample. Additional zooplankcon samples were collected at the surface in the nearshore interdunal ponds (stations 17 through 21) with a 6-liter Van Dorn bottle. Each of the four replicate samples was concentrated to 1 liter. All samples were fixed to a final concentration of 4 percent buffered formalin.

Each sample, af ter being prepared with 5 milliliters of rose-bengal dye, was analyzed for quantity and composition of all mature and immature zooplankters (excluding nauplii, rotifers, and protozoans) with dimensions greater than the plankton net's 80-micrometer mesh aperture.

2.3.2 ZOOPLANKTON RESULTS AND DISCUSSION. Results of the April 1979 sampling (Table 2.11 and Appendix E) indicated mean Lake Michigan zooplankton densities of 1211 239 organisms per cubic meter and interdunal pond mean densities of 20,090 i 14,958 organisms per cubic meter. A total of 42 taxa were observed in Lake Michigan and 33 taxa in the interdunal ponds. No effects of plant construction were observed from either the lake or the interdunal pond stations.

Since the two areas are quite dissimilar, they will be discussed separately.

2.3.2.1 Lake Michigan. Densities in Lake Michigan in April 1979 were greater at the nearfield stations (1 through 6 and 10), where the average density was 1450 1 250 organisms per cubic meter, than at the farfield stations (7 through 9), where densities averaged 972 i 180 organisms per cubic meter (Table 2.12). Density estimates by station exhibited some variability, and there were no extreme highs or lows.

Cassie (1963) indicated that a between-replicate variability (SE/R) of 22 to 44 percent could be expected. All of the stations yielded variabilities that were less than or within this range. Stations 6 and 7 showed the highest replicate variability, but this did not appear to indicate any influence of the plant on population.

Table 2.13 indicates numbers of taxa, as well as diversity and evenness, in Lake Michigan during April 1979.

O q

w Numbers of taxa in 1979 were similar to those in lapril 1978; howevec, 1979 diversity and evenness were lowe- 'his may have been a result of the large number of immature Calanoida forms, which comprised 60 percent of the total lake densities. There were no obvious changes in the composition of the zooplankton community in 1979.

Cladocerans dominated ponds B and C, with 36 and 63 percent, respectively, and C_hy,dorus h sp. was the dominant taxa. Copepods dominated the Cowles Bog fauna (64 percent).

Pond B in April 1978 exhibited low cladoceran and copepod densities, while pond C showed the reverse trend. These differences were not significant.

Diversity and number of taxa by individual pond and station are presented in Table 2.15. The diversity and evenness for all ponds for 1979 compared favorably with those in April 1978. Pond C appeared to have low diversity, probably because of the large number of immature calanoid forms. No unusual taxa or density shifts were noted.

@2.4 BENTH0S AND FISHERIES Benthos samples from April and June 1979 have been collected; data will be included in the summer 1979 quarterly report. Lake Michigan fisheries data obtained from gill nets and beach seines are unavailable at this time but will be included in the summer quarterly report. Pond fish data were not collected in April and, because of an equipment theft problem, samples were missed in June. 'Ihe problem has been alleviated, and sampling will proceed in August as usual.

2.5 ICHTHYOPLANKTON 2.5.1 METHODOLOGY. Ichthyoplankton (fish eggs and larvae) were sampled in Lake Michigan in the Bailly Study Area at stations 1 through 10 (Figure 2-1) by two methods: zooplankton net and epibenthic pump. Ichthyo-plankton ecliection with the zooplankton net was an adjunct to zooplankton sampling at stations 1 through 10. The epibenthic pump was used at stations 4 and 7; all of the demersal organisms in the vicinity of the pumping head were pumped by and into an 80-micrometer mesh net suspended in the water column at the surface of the lake. Pumping velocity was high enough to mini-mize avoidance but low enough to minimize harm to the organisms.

2.5.2 RESULTS. Samples collected in April 1979 yielded rainbow smelt eggs and yolk-sac larvae and unidentified eggs. In April 1975, the only ichthf oplankton collected was a single darter. April sampling in other years (1976, 1977, and 1978) yielded no ichthyoplankton. Densities and loca-tions of catches in April 1979 were as follows:

2.6 WATER QUALITY 2.6.1 METHODOLOGY. Water quality parameters were measured in the lake and ponds onsite as well as in the National Lakeshore area, as desig-nated by stations i through 22 in Figure 2.1. Table 2.16 indicates the stations s ampled , the water quality parameters measured, and the methods and their accuracy. Additionally, Table 2.17 lists each parameter and its Indiana Pollution Control Board standard levels; where Indiana standards were not immediately available, U.S. Public Health Service or Federal Environ-mental Protection Agency values were used.

All water quality samples were collected using either a Van Dorn whole-water sampler (or equivalent) or, for bacteria samples, sterile bottles dipped below the water's surface. g situ parameters were measured using a YSI Model 59 temperature / dissolved-oxygen meter with remote stirrer, a Beckman solu-bridge conductivity meter, a standard 4 quadrant Secchi disk, and a Beckman field-model pH meter (or equivale:t gear). Also recorded at each sampling location were wind direction and speed, air temperature, water color, percent cloud cover, and time of day. While these ancillary measure-ments are useful in interpreting some of the biological data, they are not considered part of water quality data and are not presented in the tables; they are included in sections where they help explain biological findings.

Samples from the ash-settling basins (stations 13 through 16), tt tural ponds (stations 17 through 20), and Cowles Bog (station 21) were collected at mid-depth. Lake Michigan samples from locations along the 15-foot contour (stations 1, 4, and 7) were collected from 1 meter below the surface, lake samples along the 30-foot contour (stations 2, 5, and 8) were collected from 1 meter below the surface and from 1 meter above the bottom, and lake samples along the 50-foot contour (stations 3, 6, and 9) were collected from 1 meter below the surface, at mid-depth, and from 1 meter above the bottom. All other lake samples (stations 10, 11, and 22) were collected from 1 meter below the surface. Sediment samples were collected from the substrate in the vicinities of stations 13 through 20.

0 2.6.2 RESULTS AND DISCUSSION 2.6.2.1 General Water Quality Parameter. Results of general water quality analyses for both lake and ponds during April 1979 are presented in Table 2.18. No effects of plant construction on either Lake Michigan or the interdunal ponds were indicated by the general water quality analyses.

2.6.2.1.1 Lake Michigan. Alkalinity, odor, color, and chlorine levels in April 1979 were virtually identical to those in April 1978. Levels of chloride, hardness, calcium, magnesium, potassium, sodium, sulfate, and conductivity in April 1979 were also similar to those of April 1978. Levels of fluoride in 1979 were less than detection, continuing the trend of being at or neer the lower limit of detection. Oxygen concentrations ranged from 11.9 to 13.2 milligrams per liter, and percent saturation averaged 104 (an exceedingly high dissolved oxygen at station 3 was believed to be erroneous).

All concentrations and percent saturation levels exceeded the minimum allowed levels indicated by the Indiana Stream Pollution Control Board (ISPCB). The slightly higher oxygen levels in 1979 were probably a result of lower water temperatures (6.0-7.5 C range), which increase oxygen solubility. The pH levels, ranging from 8.0 to 8.3 pH units, were all at or below the 8.5 ISPCB standard.

As mentioned previously, color level: in April 1979 were idantical to those of April 1978, all being at 1 Platinum-Ccbalt (Pt-Co) unit, an indication of very high clarity. Suspended solids levels were low, averaging 18.6 milli-grams per liter, and dissolved solids averaged 144 milligrams per liter; both values were comparable to those of April 1978. Turbidity levels were low, ranging fror. 1 to 10 NTUs, supporting the above results.

2.6.2.1.2 Ponds. The ponds can be considered to be four units: ash-settling ponds (stations 13 through 16), pond B (17 through 18), pond C (19 through 20), and Cowles Bog (station 21). Both the natural and ash-settling ponds were monitored for general water quality parameters. Generally, there were considerable differences among the ponds, but only minor differences from the data collected in April 1978.

827 2iB 2.32 science services division

@Oxygen concentrations in the ponds were somewhat lower than in the lakes, ranging from 9.2 to 13.2 milligrams per liter. Percent saturation was 85 to 114. Levels of pH were between 6.6 and 7.2 units, lower than the average of 8.2 observed in the lake. Alkalinity values were low compared to those in the lake. Conductance and hardness were generally higher in the ponds.

Concentrations of ions which would cause these higher levels - calcium, magnesium, potassium, sodium, sulfates, and chlorides - were generally higher in the ponds than in the lake. Pond C stations tended to have lower levels than the othar stations, and no explanation is readily available.

Pond water temperatures ranged from 8 8 to 12.0 C, the highest occurring in pond C and Cowles Bog, and averaged 5C higher than for the lake in April 1979 and almost 7.0 C higher than for the lake in April 19/6. The shallow nature of the pond during the spring permits it to rapidly warm.

April 1979 color values were 1 in all ponds except Cowles Bog. Previous data had shown the natural ponds (stations 17 through 21) to exhibit higher color values. There is no obvious explanation for the low color values, although the high water levels observed on site may indicate the possibility of dilu-tion.

Odor was present in all natural ponds, as it had been previously. Fluoride levels were at or below detection limits at all stations except settling pond 2 (station 14), but values observed in settling pond 2 were low and did not exceed values observed in April 1978. Total dissolved and suspended solids results were similar to those obtained in 1978: station 13 had lower dissolved solids but higher suspended solids than the other ash ponds.

Cawles Bog exhibited a high suspended solids load, but the results did not indicate a long-term change from past years, since the bog tends to change rapidly because of outside influences. Turbidity analysis yielded low values that indicated a very small amount of suspended material present during April.

2.6.2.2 Aquatic Nutrients. Results for April 1979 aquatic nutrient analyses are presented in Tabic 2.19. Mean values were as follows:

Ammonia values in Lake Michigan were considered to be moderate. The overall average at lake stations was higher than in previous sampling periods.

Ammonia values in the ash ponds and ponds B and C were higher than those reported in August and November 1978. Cowles Bog also exhibited high ammonia values, but fluctuations are not unusual due to its shallow nature. All values except one (station 8, replicate a) exceeded the applicable single-value Indiana Stream Pollution Control Board (ISPCB) standards (see Table 2.17) as well as the monthly mean value for the lake and the interdunal ponds. Ammonia will continue to be monitored, although present values should not endanger any indigenous fauna (EPA 1971).

All stations had nitrate and nitrite values that were within ISPCB standards.

April 1979 nitrate values generally exhibited a similar trend during April 1978. Average and mean nitrate values were 0.34 milligrams per liter ana 0.009 milligrams per liter, respectively, for Lake Michigan and 0.15 milli-grams per liter and 0.012 milligrams per liter, respectively, for the inter-dunal ponds. 'Ihe highest nitrite values occurred in the ash-settling ponds.

Organic nitrogen levels exhibited little variation, averaging 0.44 milligrams per liter over all stations. Values in the ash ponds were high and were three times higher than in April 1978. Ash pond levels fluctuate widely as influenced by input of bottom ash and/or fly ash. Results from pond B indi-cated little or no leaching from the ash ponds. Pond C and Cowles Bog demon-strated little change from April 1978 or November 1978.

O Orthophosphate and total phosphate levels were uniformly low. Although several total phosphate values exceeded the ISPCB standards, as did the mean values for both Lake Michigan and Cowles Bog, there were no obvious biologi-cal indications of the increased levels. Orthophosphate and total phosphate values were extremely low in the ash ponds and in ponds B and C.

Silicate levels in April 1979 were higher than in April and November 1978, but 'here was no indication of a " bloom" condition for diatoms as a result of ti.e higher silicate levels. The ash ponds and Cowles Bog exhibited the high-est silicate levels, while the averages for Lake Michigan and pond B were similar and moderate. Lowest values observed in April 1979 were in pond C.

There are no prescribed ISPCB limits for silicates. The values recorded during April are different from those described previously in respect to the declining silicate values in Lake Michigan (i.e. , the concentrations observed during April are slightly higher than the mean annual concentration expected, beced on an observed 20 year trend of declining silicate levels).

2.6.2.3 Indicators of Contamination. Nine indicators of contamination were examined in the interdunal ponds during April 1977. As indicated in Table 2.20, fecal coliform bacteria were less than 1 per 100 milliliters at all stations and total colifonn bacteria values were less than 1 per 100 milliliters at ash pond stations 14 and 15; at stations 13, 17, 19, 20, and 21, however, total coliform bacteria exceeded ISPCB standmrds. It should be noted that the ISPCB standards were developed for Lake Michigan and do not apply directly to the ponds. Values at the latter stations ranged from less than 1 to 500 per 100 milliliters. During previous years, high total coli-form counts had been attributed to migratory birds, and it is likely that this was the situation this year.

Biological oxygen demand (BOD), chemical oxygen demand (CCD), and total organic carbon (TOC) had lov values except in Cowles Bog, a trend which has been observed during the last several sampling periods.

Hexane extraction of oils and grease produced the highest values in the ash ponds and pond B (less than 0.1 to 36.4 milligrams per liter), while pond C 827 222 7.36 science services division

• S - surface and Cowle- Bog were similar to one another. The ovecall va' aes for all ponds were alLghtly higher in April 1979 than in April 1978 (12.4 versus 7.4 milli-grams per liter).

Phenol concentrations ranged from less than 0.005 mil',i; rams per liter to 0.046 milligrams per liter, whereas 1978 cencentrations ranged from less than 0.005 to 0.007. No direct source was evident. Methylene-blue active sub-stances (detergent-like substances) were below the detection limits, as they had been during April 1978.

2.6.2.4 Trace Elements in Interdunal Ponds. Trace elements sere moni-tored in the interdunal ponds during April. As indicated in Table 2.21 cadmium exceeded the ISPCB standard in the ash ponds only ato was aear or at the detection limits in ponds B and C and Cowles Bog. Iror. and aanganese also exceeded the state standards at most c stions. Iror, and sanganese values have also been high 11 previous sampling periods. All o*.her trace ele-ment analyses indicated nothing unusual. Concentrations of copper, nickel, and zine were higher in the ash ponds than in the other sampling partas but should not be harmful to the biota.
