SUMMARY

AND CONCLUSIONS 3 There were no significant environmental events during 2010. During 2010, no significant changes to operations that could affect the environment were made at Beaver Valley Power Station. As in previous years, results of the BVPS environmental programs did not indicate any adverse environmental impactsfrom station operation.

1.3 ANALYSIS OF SIGNIFICANT ENVIRONMENTAL CHANGE i During 2010, no significant changes were made at BVPS to cause significant negative. affect on the environment.

1.4 AQUATIC MONITORING PROGRAM The 2010 Beaver Valley Power Station (BVPS) Units 1 and 2 Non-Radiological Monitoring Program consisted of an Aquatic Program that included surveillance and field sampling of the Ohio River's aquatic life in the vicinity of the station. The Aquatic Program is an annual program conducted to provide baseline aquatic resources data, to assess the impact of the operation of BVPS on the aquatic ecosystem of the Ohio River, and to monitor for potential impacts of biofouling organisms (Corbicula and zebra mussels) on BVPS operations. This is the 35g year of operational environmental monitoring for Unit I and the 2 4 year for Unit 2. As in I

previous years, the results of the program did not indicate any adverse environmental impact to I the aquatic life in the Ohio River associated with the operation of BVPS.

The results of the 2010 benthic macroinvertebrate survey conducted in May and September indicated a normal community structure exists in the Ohio River both upstream and downstream of the BVPS. These benthic surveys are a continuation of a Fate and Effects Study conducted from 1990 through 1992 for the Pennsylvania Department of Environmental Protection (PADEP) to assess the ecosystem impacts of the molluscicides Betz Clamtrol CT-1, CT-2, and Powerline 3627 that are used to control biofouling organisms at BVPS. To date the results of the benthic studies have not indicated any impacts of operation at the BVPS including the use these biocides on the benthic community below the BVPS discharge.

Substrate was probably the most important factor influencing the distribution and abundance of the benthic macroinvertebrates in the Ohio River near BVPS. The generally soft muck-type substrate along the shoreline found in 2010 and previous years was conducive to segmented worm (oligochaete) and midge (chironomid) proliferation. Fifty (50) macroinvertebrate taxa were identified during the 2010 monitoring program. One new taxon, Corophididae (a freshwater amphipod) was added to the cumulative taxa list of macroinvertebrates collected near BVPS. No state or Federal threatened or endangered macroinvertebrate species were collected during 2010. In May were the most frequently collected group of macroinvertebrate, while in September chironomids were the most frequently collected group. There were no major differences in the community structure between control and non-control stationsthat could be attributedto operation of BVPS. The overall community structure has changed little since pre-operationalyears, and program results did not indicate that BVPS operations were affecting the benthic community of the Ohio River.

2010 Annual Environmental Report 2 I FENOC (BVPS)

I

The fish community of the Ohio River near the BVPS was sampled in May (spring), July (summer), September (fall) and November (winter) of 2010 with nighttime electrofishing and daytime seining. Since monitoring began in the early 1970's, the number of identified fish taxa has increased from 43 to 78 for the New Cumberland Pool.

Benthivores (bottom feeders including suckers and buffalo) and forage species (e.g. gizzard shad and emerald shiners) were generally collected in the highest numbers in 2010. The.total number of forage species collected in 2010 was comparable to 2009, however. The number of juvenile bluegills collected in 2010 was higher than in any previous year. Variations in annual catch were probably attributable to normal fluctuations in the population size of the forage species and the predator populations that rely on them. Forage species, such as gizzard shad and emerald shiner with high reproductive potentials, frequently respond to changes in natural environmental factors (competition, food availability, cover, and water quality) with large fluctuations in population size. This, in turn, influences their appearance in the sample populations during annual surveys. Spawning/rearing success due to abiotic factors is usually the determining factor of the size and composition of a fish community.

In 2010 the annual catch rate was 1.09 fish per minute. The greatest catch rate in 2010 occurred in spring (May) when the catch rate was 2.20 fish per minute. Sauger, smallmouth bass, and shorthead redhorse sucker contributed to the majority of this total. The lowest catch rate occurred in summer (July) with a rate of 0.32 fish per electrofishing minute. The annual catch rates were consistent over the four years ranging from a high of 1.98 fish per minute in 2008 to 1.09 in 2010.

Little difference in the species composition of the catch was observed between the control (Station 1) and non-control (Stations 2A, 2B and 3) stations. Habitat preference and availability were probably the most important factors affecting where and when fish were collected. Results from the 2010fish surveys indicated that a normal community structurefor the Ohio River exists near BVPS based on species composition and relative abundance. In 2010, there was no indication of negative impact to the fish community in the Ohio River from the operation of BVPS.

The monthly reservoir ponar samples collected in Units 1 and 2 cooling towers and the four samples collected at the intake during 2010 indicated that Corbicula were entering and colonizing the station. Overall, the numbers of Corbicula collected in the samples were comparatively low, which continued the trend over the past few years offewer Corbicula and reflected a water-body-wide trend observed in the Ohio River.

In 1995, live zebra mussels were collected for the first time by divers in the BVPS main intake and auxiliary intake structures during scheduled cleanings. Overall, both the number of observations and densities of settled mussels were similar in 2003-present although somewhat higher in 2008 and 2010. Overall, veliger densities in 2010 were greater than 2009. This is likely due to annual variability in numbers of veligers in the Ohio River. Although densities of settled mussels in the vicinity of BVPS are low compared to other populations such as in the Lower Great Lakes, densities comparable to those in the Ohio River are sufficient to cause problems in the operation of untreatedcooling water intake systems.

5.0 AQUATIC MONITORING PROGRAM This section of the report summarizes the Non-Radiological Environmental Program conducted for the BVPS Units I and 2; Operating License Numbers DPR-66 and NPF-73. This is a non-mandatory program, because on February 26, 1980, the Nuclear Regulatory Commission (NRC) granted BVPS's request to delete all of the Aquatic Monitoring Program, with the exception of the fish impingement program (Amendment No. 25), from the Environmental Technical Specifications (ETS). In 1983, BVPS was permitted to also delete the fish impingement studies from the ETS program of required sampling along with non-radiological water quality requirements. However, in the interest of providing an uninterrupted database, BVPS has continued the Aquatic Monitoring Program.

The objectives of the 2010 environmental program were:

• To monitor for any possible environmental impact of BVPS operation on the benthic macroinvertebrate and fish communities in the Ohio River; 0 To provide a low level sampling program to continue an uninterrupted environmental database for the Ohio River near BVPS, pre-operational to present; and

• To evaluate the presence, growth, and reproduction of macrofouling Corbicula (Asiatic clam) and zebra mussels (Dreissenaspp.) at BVPS.

5.1 SITE DESCRIPTION BVPS is located on an approximately 453-acre tract of land on the south bank of the Ohio River in the Borough of Shippingport, Beaver County, Pennsylvania. The Shippingport Atomic Power Station once shared the site with BVPS before being decommissioned. Figure 5.1 is a plan view of BVPS. The site is approximately 1 mile (1.6 kin) from Midland, Pennsylvania; 5 miles (8 km) from East Liverpool, Ohio; and 25 miles (40 km) from Pittsburgh, Pennsylvania. The population within a 5-mile (8 km) radius of the plant is approximately 18,000. The Borough of Midland, Pennsylvania has a population of approximately 3,500.

The station is situated at Ohio River Mile 34.8 (Latitude: 400 36' 18"; Longitude: 800 26' 02") at a location on the New Cumberland Pool that is 3.1 river miles (5.3 kin) downstream from Montgomery Lock and Dam and 19.6 miles (31.2 km) upstream from New Cumberland Lock and Dam. The Pennsylvania-Ohio-West Virginia border is 5.2 river miles (8.4 km) downstream from the site. The river flow is regulated by a series of dams and reservoirs on the Beaver, Allegheny, Monongahela, and Ohio Rivers and their tributaries.

The study site lies along the Ohio River in a valley, which has a gradual slope that extends from the river at an elevation of 665 ft (203 m) above mean sea level; to an elevation of 1,160 ft (354 m) along a ridge south of BVPS. The plant entrance elevation at the station is approximately 735 ft (224 m) above mean sea level.

2010 Annual Environmental Report 5 FENOC (BVPS)

i BVPS Units 1 and 2 have a thermal rating of 2,900 (MWt) each. Units 1 & 2 have a design electrical rating of 974 and 969 MWe, respectively. The circulating water systems for each unit 3

are considered a closed cycle system with continuous overflow, using a cooling tower to minimize heat released to the Ohio River. Commercial operation of BVPS Unit I began in 1976 and Unit 2 began operation in 1987.

3 5.2 STUDY AREA I The environmental study area was established to assess potential impacts and consists of four sampling stations, each having a north and south shore (Figure 5.1). Station 1 is located at River Mile (RM) 34.5, approximately 0.3 miles (0.5 km) upstream of BVPS and is the control station.

Station 2A is located approximately 0.5 miles (0.8 km) downstream of the BVPS discharge structure in the main channel. Station 2B is located in the back channel of Phillis Island, also 0.5 miles downstream of the BVPS discharge structure. Station 2B is the principal non-control I

station because the majority of discharges from BVPS Units 1 and 2 are released to this back channel. Station 3 is located approximately two miles (3.2 km) downstream of BVPS and only rarely is influenced by the BVPS discharge.

5.3 METHODS Shaw Environmental, Inc. (Shaw) was contracted to perform the 2010 Aquatic Monitoring Program as specified in BVBP-ENV-001-Aquatic Monitoring (procedural guide). This 3

procedural guide references and describes in detail the field and laboratory procedures used in the various monitoring programs, as well as the data analysis and reporting requirements. These procedures are summarized according to task in the following subsections. Sampling was conducted according to the schedule presented in Table 5.1.

5.3.1 Benthic Macroinvertebrate Monitoring The benthic macroinvertebrate monitoring program consisted of river bottom sampling using a Ponar grab sampler at four stations on the Ohio River. Prior to 1996, duplicate sampling occurred at Stations 1, 2A, and 3, while triplicate sampling occurred at Station 2B (i.e., one sample at each shoreline and mid-channel) (Figures 5.1 and 5.2). In 1996, a review of the sampling design indicated that sampling should be performed in triplicate at each station to conform to standardized U.S. Environmental Protection Agency (USEPA) procedures.

Therefore, starting in 1996, triplicate samples were taken at Stations 1, 2A, and 3, as in 1995, I

with triplicate samples also collected at each shore and mid-channel location at Station 2B. A petite Ponar dredge was used to collect these samples, replacing the standard Ponar dredge used in prior studies.

I Benthic macroinvertebrate sampling was conducted in May and September 2010. For each 2010 field effort, 18 benthic samples were collected and processed in the laboratory. All field 3

I

procedures and data analyses were conducted in accordance with the procedural guide. The contents of each Ponar grab sample were gently washed through a U.S. Standard No. 30 sieve and the retained contents were placed in a labeled bottle and preserved in ethanol. In the laboratory, rose bengal stain was added to aid in sorting and identifying the benthic organisms.

Macroinvertebrates were sorted from each sample, identified to the lowest taxon practical and counted. Mean density (number/m 2) for each taxon was calculated for each replicate. Four indices used to describe the benthic community were calculated: Shannon-Weiner diversity index, evenness (Pielou, 1969), species richness, and the number of taxa. These estimates provide an indication of the relative quality of the macroinvertebrate community.

5.3.2 Fish Monitoring Fish sampling was conducted in 2010 to provide a continuous baseline of data and to detect possible changes that may have occurred in the fish populations in the Ohio River near BVPS.

Fish population surveys have been conducted in the Ohio River near BVPS annually from 1970 through 2010. These surveys have resulted in the collection of 73 fish species and five different hybrids.

Adult fish surveys were scheduled to be performed in May, July, September, and November 2010. During each survey, fish were scheduled to be sampled by standardized electrofishing techniques at four stations (Stations 1, 2A, 2B and 3) (Figure 5.3). Seining was scheduled to be performed at Station 1 (north shore) and Station 2B (south shore of Phillis Island) to sample species that are generally under-represented in electrofishing catches (e.g., young-of-the-year fish and small cyprinids). Sampling was successfully completed as scheduled.

Night electrofishing was conducted using a boat-mounted electroshocker with floodlights attached to the bow. A Smith-Root Type VI A variable voltage, pulsed-DC electrofishing unit powered by a 5-kW generator was used. The voltage selected depended on water conductivity and was adjusted to provide constant amperage (4-6 amps) of the current through the water. The north and south shoreline areas at each station were shocked for at least 10 minutes of unit "on" time (approximately five minutes along each shore) during each survey.

When large schools of fish of a single non-game species such as gizzard shad and shiners were encountered during electrofishing efforts, all of the stunned fish were not netted and retrieved onboard the boat. A few fish were netted for verification of identity, and the number of observed stunned fish remaining in the water was estimated. The size range of the individual fish in the school was also estimated and recorded. This was done in an effort to expedite sample processing and cover a larger area during the timed electrofishing run. Regardless of the number of individuals, all game fish were boated when observed.

Fish seining was performed at Station 1 (control) and Station 2B (non-control) during each of the four 2010 BVPS fishery surveys. A. 30-ft long bag seine made of 1/4-inch nylon mesh netting was used to collect fish located close to shore in 1 to 4 ft of water. Three seine hauls were performed at both Station 1 (north shore) and Station 2B (south shore of Phillis Island) during 2010 Annual Environmental Report 7 FENOC (BVPS)

each survey.

Fish collected during electrofishing and seining efforts were processed according to standardized procedures. All captured game fishes were identified to species, counted, measured for total length (nearest 1 mm), and weighed (nearest I g for fish less than or equal to 1000 g and the nearest 5 g for all other fish). Non-game fishes were counted, and a random subsample of lengths was taken. Live fish were returned to the river immediately after processing was completed. All fish that were unidentifiable or of questionable identification and were obviously not on the endangered or threatened species list were placed in plastic sample bottles, preserved, labeled and returned to the laboratory for identification. Any species of fish that had not previously been collected at BVPS was retained for the voucher collection. Any threatened or endangered species (if collected) would be photographed and released.

5.3.3 CorbiculaDensity Determinations for Cooling Tower Reservoirs The Corbicula Monitoring Program at BVPS includes sampling the circulating river water and the service water systems of the BVPS (intake structure and cooling towers). The objectives of the ongoing Monitoring Program are to evaluate the presence of Corbicula at BVPS, and to evaluate the potential for and timing of infestation of the BVPS. This program is conducted in conjunction with a program to monitor for the presence of macrofouling zebra mussels (see Section 5.3.5).

Corbicula enter the BVPS from the Ohio River by passing through the water intakes, and eventually settle in low flow areas including the lower reservoirs of the Units 1 and 2 cooling towers. The density and growth of these Corbicula were monitored by collecting monthly samples from the lower reservoir sidewalls and sediments. The sampler used on the sidewalls consisted of a D-frame net attached behind a 24-inch long metal scraping edge. This device was connected to a pole long enough to allow the sampler to extend down into the reservoir area from the outside wall of the cooling tower. Sediments were sampled with a petite Ponar dredge.

Cooling tower reservoir sampling was historically conducted once per month. Beginning in December 1997, it was decided to forego sampling in cold water months since buildup of Corbicula does not occur then. Monthly sampling has been maintained throughout the warmer water months of the year. In 2010 sampling began in March and ended in early November.

In 2010, once each month (March through November), a single petite Ponar grab sample was taken in the reservoir of each cooling tower to obtain density and growth information on Corbicula present in the bottom sediment. The samples collected from each cooling tower were returned to the laboratory and processed. Samples were individually washed, and any Corbicula removed and rinsed through a series of stacked U.S. Standard sieves that ranged in mesh size from 1.00 mm to 9.49 mm.. Live and dead clams retained in each sieve were counted and the numbers were recorded. The size distribution data obtained using the sieves reflected clam width, rather than length. Samples containing a small number of Corbicula were not sieved; individuals were measured and placed in their respective size categories. A scraping sample of 2010 Annual Environmental Report 8 FENOC (BVPS)

about 12 square feet was also collected at each cooling tower during each monthly sampling effort. This sample was processed in a manner consistent with the petit Ponar samples.

Population surveys of both BVPS cooling tower reservoirs have been conducted during scheduled outages (1986 to present) to estimate the number of Corbicula present in these structures. During the scheduled shutdown period for each unit, each cooling tower reservoir bottom is sampled by petite Ponar at standardized locations within the reservoir. Counts of live and dead clams and determination of density were made. There were no scheduled outages during 2010 when samples were collected.

5.3.4 CorbiculaJuvenile Monitoring The Corbiculajuvenile study was designed to collect data on Corbicula spawning activities and growth of individuals entering the intake from the Ohio River. From 1988 through 1998, clam cages were deployed in the intake forebay to monitor for Corbiculathat entered the BVPS.

Observational-based concerns that the clam cages would quickly clog with sediment during high sediment periods and, as a result, would not effectively sample for Corbicula, led to an evaluation of an alternate sampling technique. From April through June 1997, a study was conducted to compare the results of the clam cage samplers to a petite Ponar dredge technique to determine Corbicula presence and density in the BVPS intake bays. It was hypothesized that using a Ponar sampler to collect bottom sediments and analysis of those sediments would provide a more representative sample of Corbicula settlement and growth rates, and had the added benefit of not requiring confined space entry to conduct the sampling. Results of the study confirmed this hypothesis.

During the 1998 sampling season, at the request of BVPS personnel, all clam cages were removed after the May 18th collection. Monthly petite Ponar grabs from the forebay in the intake building continued thereafter. Samples were processed in the same manner as Cooling Tower Samples (Section 5.3.3).

From 2002 to present, because of site access restrictions, sampling with the petite Ponar has been moved to the Ohio River directly in front of the Intake Structure Building. Collections are presently made in conjunction with the fisheries sampling (May, July, September, and November). During each sampling month two Ponar grabs are taken approximately 20 feet off shore of the intake building. These grab samples are processed in the same manner as when they

• werecollected from within the Intake Structure Building.

5.3.5 Zebra Mussel Monitoring The Zebra Mussel Monitoring Program includes sampling the Ohio River and the circulating river water system of the BVPS.

2010 Annual Environmental Report 9 FENOC (BVPS)

The objectives of the Monitoring Program were:

(1) To identify if zebra mussels were in the Ohio River adjacent to BVPS and provide early warning to operations personnel as to their possible infestation; (2) To provide data as to when the larvae were mobile in the Ohio River and insights as to their vulnerability to potential treatments; and (3) To provide data on their overall density and growth rates under different water temperatures and provide estimates on the time it requires these mussels to reach the size and density that could impact the plant.

The zebra mussel sampling for settled adults was historically conducted once per month, yearlong. Beginning in December 1997, it was decided to forego sampling in the colder water months of each year, since buildup of zebra mussels, does not occur then. Monthly sampling has been maintained throughout the balance of the year. In 2010 sampling occurred from March through November.

A pump sample for zebra mussel veligers was collected at the barge slip location monthly from April through October in 1996 and 1997. The scope of the sampling was expanded in 1998 to also include the intake structure. In June 1998, the Emergency Outfall and Emergency Outfall Impact Basin locations were also added. Additional pump samples were collected from the cooling towers of Unit 1 and Unit 2 in October 1998. In 2010 veliger sampling began in April and was conducted monthly through October.

At the Intake Structure and Barge Slip the following surveillance techniques were used:

• Wall scraper sample collections on a monthly basis (March through November) from the barge slip and the riprap near the intake structure to detect attached adults; and

• Pump sample collections from the barge slip and outside the intake structure, to detect the planktonic early life forms (April through October).

At each of the cooling towers the following techniques were used:

• Monthly reservoir scraper sample collections in each cooling tower (March through November); and 0 Pump samples in April through October to detect planktonic life forms.

At the Emergency Outfall and the Splash Pool the following techniques were used:

• Monthly scraper sample collections in each (March through November); and 3

• Pump samples in each from April through October to detect planktonic life forms.

5.3.6 Reports Each month, activity reports that summarized the activities that took place the previous month were prepared and submitted. These reports included the results of the monthly Corbicula/zebra mussel monitoring including any trends observed and any preliminary results available from the benthic and fisheries programs. The reports addressed progress made on each task, and reported any observed biological activity of interest.

5.4 RESULTS OF THE AQUATIC MONITORING PROGRAM The following sections summarize the findings for each of the program elements. Sampling dates for each of the program elements are presented in Table 5.1.

5.4.1 Benthic Macroinvertebrate Monitoring Program Benthic surveys were scheduled and performed in May and in September 2010. Benthic samples were collected using a petite Ponar grab sampler at Stations 1, 2A, 2B, and 3 (Figure 5.2).

Triplicate samples were taken off the south shore at Stations 1, 2A, and 3. Sampling at Station 2B, in the back channel of Phillis Island, consisted of triplicate petite Ponar grabs at the south side, middle, and north side of the channel (i.e., Sample Stations 2B1, 2B2, and 2B3, respectively).

Substrate type is an important factor in determining the composition of the benthic community.

The habitats in the vicinity of BVPS are the result of damming, channelization, and river traffic.

Shoreline habitats at the majority of sampling locations were generally in depositional areas that consisted of soft muck substrates composed of mixes of sand, silt, and detritus. One exception was along the north shoreline of Phillis Island at Station 2A where hard-pan clay overlain with a thin layer of fine sand dominated. The other distinct habitat, hard substrate (gravel and cobble),

was located in mid-channel of the back channel of Phillis Island. The hard substrate was probably the result of channelization and on going scouring by river currents. In general, the substrates found at each sampling location have been consistent from year to year.

2010 Annual Environmental Report 11 FENOC (BVPS)

Fifty (50) macroinvertebrate taxa were identified during the 2010 monitoring program (Tables 2

5.2 and 5.3), which was four less than in 2010. A mean density of 2,709 macroinvertebrates/m 2 was collected in May and 1,591/mi2 in September (Table 5.4). As in previous years, the macroinvertebrate assemblage during 2010 was dominated by burrowing organisms typical of soft unconsolidated substrates. (segmented worms), mollusks (clams and snails) and chironomid (midge fly) larvae were abundant (Table 5.4). In contrast to 2007 through 2009, the total mean density of organism was. higher in May than in September. Higher densities of immature in May compared to previous years caused this change.

Thirty-five (35) taxa were present in the May 2010 samples. Thirty-eight (38) taxa were present in the September samples (Table 5.3.1 and 5.3.2). Twenty-three (23) of the 50 taxa were present I in both May and September. As in 2008 and 2009, immature tubificid worms were numerically the most abundant organism in both May and September. 3 The Asiatic clam (Corbicula) has been observed in the Ohio River near BVPS from 1974 to present. Zebra mussels were first collected in the BVPS benthic samples in 1998. Adult zebra mussels, however, were detected in 1995 and 1996 by divers in the BVPS main and auxiliary intake structures during scheduled cleaning operations. Zebra mussel veligers, adults and juveniles were collected during the 1997-2010 sampling programs (see Sections 5.4.5 Zebra Mussel Monitoring Program). Both live Corbicula and zebra mussels were collected in benthic macroinvertebrate samples in 2010.

In 2010 one new taxon was added to the cumulative taxa list of macroinvertebrates collected I near BVPS (Table 5.2). The new taxon was Corophididae, a fresh water Amphipod (scud). No state or Federal threatened or endangered macroinvertebrate species were collected during 2010. 1 In the May 2010 samples, accounted for the highest mean density of macroinvertebrates and chironomids had the second highest (2,281/mi2 or 84 percent of the total density and 339/M2 or 13 percent, respectively) (Table 5.4). Mollusks and had a mean density of only 24/m2 . Organisms other then, chironomids and mollusks were present at a density of 65/m 2 in May.

I In September 2010 samples, chironomids accounted for the highest mean density of I macroinvertebrates and had the second highest (6931/m2 or 44 percent of the total density and 671/iM2 or 42 percent, respectively) (Table 5.4). Mollusks had the third highest mean density in September 2010 (179/M 2 or 11 percent) while the "others" category had the fourth highest mean l density (48/M2 or 3 percent).

In May 2010, the highest density of macroinvertebrates (6,063/M 2) occurred at Station 2B3. In September, the highest density of macroinvertebrates also occurred at Station 2A (3,168/M 2). In 1

May the lowest mean density of organisms occurred at Station 3 (846/m 2). In September, the lowest mean density of organisms also occurred at Station 3 (889/M2).

For a comparison of the control to non-control stations, Station 1 was designated the control station, because it is always out of the influence of the BVPS discharge and Station 2B (mean density of Station 2B 1, 2B2, and 2B3) was designated as the non-control station, since it is the 2010 Annual Environmental Report 12 3 FENOC (BVPS)

I

station most regularly subjected to BVPS's discharge. Stations 3 and 2A may be under the influence of the plume under certain conditions, but it is unlikely that they are regularly influenced by BVPS.

The mean density of macroinvertebrates in the non-control station was 2.3 times higher (4,022/M2) than that of the control station (1,763/M 2) in May (Table 5.5). The high density of in the non-control samples (3,650/m 2) accounted for the majority of this difference. A similar difference in density occurred in 2008 and 2009. Overall the differences probably reflect the natural differences in substrate and natural heterogeneous distributions of these organisms between the stations rather than project-related impacts.

In September, the density of macroinvertebrates present at the control (1,720/m 2) was about 1.4 times greater than at the non-control station (1,255/m 2). Differences were within the expected range of variation for natural populations of macro invertebrates.

Indices that describe the relative diversity, evenness, and richness of the macroinvertebrate population structure among stations and between control and non-control sites were calculated.

A higher Shannon-Weiner diversity index indicates a relatively better structured assemblage of organisms, while a lower index generally indicates a low quality or stressed community.

Evenness is an index that estimates the relative contribution of each taxon to the community assemblage, the closer to 1.00, the healthier the community. The community richness is another estimate of the quality of the macroinvertebrate community with a higher richness number indicating a healthier community.

The Shannon-Weiner diversity indices in May 2010 collections ranged from 0.19 at Station 1 to 1.00 at Station 2A (Table 5.6). In May evenness ranged from 0.2 at Station 1 to 0.83 at Station 2A. Richness was greatest at Stations 2A and 3 (3.19) and lowest at Station 1 (1.66). The overall low indices at Station 1 and 2A are attributed to the relatively few species (9) collected. This low number of organisms likely is due to natural variation in the Ohio River rather than due to BVPS operations. The Shannon-Weiner diversity of the macroinvertebrate community (0.57-1.02) and richness (2.42-4.45) in September 2010 were higher than in May, while evenness was comparable. There was also generally an increase in the number of taxa present in September compared to May. Relatively high numbers of taxa are frequently present in early fall due to the increased numbers of aquatic stages of insects, especially chironomids, as well as the ability to identify to lower taxonomic levels many of the tubificids that are lumped together when immature.

In May 2010, the number of taxa, diversity, eveness and richness indices were appreciably lower in the control station (Station 1) than in the non-control stations (2B1, 2B2, 2B3) (Table 5.6). In September 2010 the indices between the control and non-control stations were, in general, comparable. Similar differences were apparent in the previous three study years and were likely due to natural variations in the local populations at these locations. No impacts of the BVPS on the benthic community, as measured by differences between control and non-control zones, were evident in either May or September.

Substrate was probably the most important factor controlling the distribution and abundance of 2010 Annual Environmental Report 13 FENOC (BVPS)

the benthic macroinvertebrates in the Ohio River near BVPS. Soft, mucky substrates that generally existed along the shoreline are conducive to oligochaete, chironomid, and mollusk habitation and limit species of macroinvertebrates that require a more stable bottom.

The density of macroinvertebrates in May and September 2010 fell within the range of densities of macroinvertebrates collected at BVPS in previous years (Table 5.7). The community structure has changed little since pre-operationalyears, and the available evidence does not indicatethat B VPS operationshave affected the benthic community of the Ohio River.

3 5.4.2 Fish Sampling Program In 2010, 463 fish representing 27 taxa were collected (i.e., handled) during BVPS surveys by electrofishing and seining (Table 5.8). The total number of taxa included Lepomis sp., which I were small juvenile sunfish that could not be readily identified to species. All taxa collected in 2010 were previously encountered at BVPS. The most common species in the 2010 BVPS surveys, which were collected by electrofishing and seining combined, were bluegill (23.5% of 3

the total catch), emerald shiner (19.7%), gizzard shad (10.2%), and shorthead redhorse sucker (7.1%). None of the remaining 23 species contributed to more than 5 percent of the total handled catch. The most frequently observed but not handled fish in 2010 were unidentified redhorse suckers (Table 5.15). Game fish collected in 2010 included channel catfish, bluegill, flathead catfish, white bass, smallmouth bass, sauger, walleye, pumpkinseed, and spotted bass.

Game fish represented 40.8% of the total handled catch, 23.5% of which were bluegills.

A total of 176 fish, representing 18 taxa, was collected by electrofishing in 2010 (Table 5.9).

Shorthead redhorse suckers, white bass and sauger accounted for the greatest portion of the 2010 electrofishing catch (18.8%, 11.9 and 11.3%, respectively) followed by smallmouth bass I

(10.8%), golden redhorse sucker (8.5%), gizzard shad (7.4%), silver redhorse sucker (6.3%) and smallmouth buffalo (5.7%). No other species collected contributed to greater than five percent of the total catch. Fish observed and not collected in the 2010 electrofishing study are presented in Table 5.15. 3 A total of 287 fish representing 16 taxa was collected by seining in 2010 (Table 5.10). The most abundant taxa collected were bluegill (38.0% of the total catch) and emerald shiner (31.7%)

followed by gizzard shad (11.9%) and spotfin shiner (5.2%). No other species collected contributed to greater than five percent of the total catch. The game species were only collected I

as juveniles.

A total of 102 fish representing 16 species was captured during the May 2010 sampling event (Table 5.11). An additional species, common carp, were observed, but not boated during the May field efforts Table 5.15). Ninety (90) fish representing 14 were collected during electrofishing.

Shorthead redhorse sucker (24.4% of the total catch), sauger (17.8%), smallmouth bass (14.4%)

I and golden redhorse sucker (12.2%) were the most common species boated during the electrofishing effort. No other species contributed to more than five percent of the May electrofishing catch. Channel catfish, sauger, smallmouth bass, spotted bass, white bass and I

2010 Annual Environmental Report 14 FENOC (BVPS) 1

walleye were the game species collected in May. Twelve fish; nine emerald shiner, two spotfin shiner, and one mimic shiner, were collected by seine netting in May.

A total of 16 fish representing 9 species was captured during the July 2010 sampling event (Table 5.12). A total of 13 fish representing 11 species was collected during electrofishing efforts. Smallmouth buffalo (30.8% of the total catch) was the most common species boated during the electrofishing effort. An additional nine fish; seven unidentified redhorse suckers, one common carp and one mooneye were observed during electrofishing efforts, but not boated (Table 5.15). Channel catfish and flathead catfish were the game species collected during the July electrofishing study (Table 5.12). Three emerald shiners were the only fish collected during seining efforts in July.

During the September 2010 sampling event, 89 fish representing 19 taxa were collected (Table 5.13). A total of 26 fish representing 9 species was collected during electrofishing efforts. White bass and gizzard shad were the most abundant species, each contributing to 23.1 percent of the fish collected during electrofishing. Spotted bass (15.4%), Smallmouth bass (11.5%), shorthead redhorse sucker (7.7%), and golden redhorse sucker (7.7%) were the only other species that contributed to greater than five percent of the total electrofishing catch. A total of 63 fish was collected during seining efforts. Juvenile gizzard shad (54.0% of the total catch) were the most abundant species in the seine catch. Bluegill juveniles, pumpkinseed juveniles, sauger, smallmouth bass, white bass, and unidentified juvenile sunfish were the game fish collected in September.

During the November 2010 sampling event, 256 fish representing 17 taxa were captured (Table 5.14). A total of 47 fish representing 13 species were collected during electrofishing. White bass was the most abundant species collected by electrofishing and contributed to 27.7% of the total. pOther relatively abundant species were shorthead redhorse sucker (14.9%), silver redhorse sucker (10.6%), gizzard shad (8.5%), smallmouth bass (6.4%), sauger (6.4%) and freshwater drum (6.4%). A total of 209 fish representing four species were collected during seine netting.

Juvenile bluegill (51.7% of the fish collected and emerald shiner (37.8%) were the must abundant species during seine efforts. Game species collected in November included white bass, smallmouth bass, sauger, spotted bass, and bluegills.

Electrofishing catch rates are presented in Tables 5.16, 5.17, 5.18, and 5.19 for fish that were boated and handled during the 2007 through 2010 surveys by season (FENOC 2008, 2009, and 2010. In 2010, the annual catch rate was 1.09 fish per minute. The greatest catch rate in 2010 occurred in spring (May) when the catch rate was 2.20 fish per minute. Sauger, smallmouth bass, and shorthead redhorse sucker contributed to the majority of this total. The lowest catch rate occurred in summer (July) with a rate of 0.32 fish per electrofishing minute. The annual catch rates were consistent over the four years ranging from a high of 1.98 fish per minute in 2008 to 1.09 in 2010. Over the four years, the highest seasonal catch rates occurred in May 2008 (4.54 fish per minute) and in May 2010 (2.20 fish per minute). The lowest seasonal catch rates occurred in July 2008 (0.68 fish per minute) and July 2010 (0.32 fish per minute)..

The results of the electrofishing sampling effort (Table 5.9) did not indicate any major differences in species composition between the control station (1) and the non-control Stations 2010 Annual Environmental Report 15 FENOC (BVPS)

i 2A, 2B, and 3. A greater number of fish representing more species was captured at non-control stations than control stations. This was most likely due to the extra effort expended at non-control stations versus control stations (i.e., there are three non-control stations and only one control station). In 2010, a fewer individuals, but a comparable number of species were i collected by seines at the control station compared to the non-control station (Table 5.10). The collection of a school of juvenile bluegills in one seine haul at the non-control station in November resulted in this lager number of individuals.

In 2010, species composition remained comparable among stations. Common taxa collected in the 2010 surveys by all methods included redhorse sucker species, sauger, smallmouth bass, bluegill, gizzard shad and emerald shiner. Little difference in the species composition of the catch and relative composition was observed between the control (1) and non-control stations (2A, 2B and 3), except for emerald shiners and juvenile bluegills. Over 99 percent of the bluegill3 collected in 2010 were from one seine haul that was conducted at the non-control station in November. Similarly over 66 percent of the emerald shiners were collected in one seine haul at the control station. This is likely due to the schooling nature of these species. This and habitat preference and availability were probably the most important factors affecting where and when 3

different species of fish are collected.

The results of the 2010 fish surveys indicated that there is a normal community structure in the Ohio River in the vicinity of BVPS based on species composition and relative abundance of fish observed during the surveys. Benthivores (bottom feeders including suckers and buffalo) and forage species (e.g. gizzard shad, emerald shiners) were generally collected in the highest numbers. In 2010 a large number of juvenile bluegill, which also serve as forage when small, were collected. The numbers of forage species were comparable to in 2009, but less than in some past years. Variations in annual catch were probably attributable to normal fluctuations in the population size of the forage species and the predator populations that rely on them. Forage species, such as gizzard shad and emerald shiner with high reproductive potentials, frequently respond to changes in natural environmental factors (competition, food availability, cover, and water quality) with large fluctuations in population size. This, in turn, influences their appearance in the sample populations during annual surveys. Spawning/rearing success due to abiotic factors is usually the determining factor of the size and composition of a fish community.

In addition, differences in electrofishing catch rate can be attributed to environmental conditions that prevail during sampling efforts. High water, increased turbidity, and swift currents that occur during electrofishing efforts in some years can affect the collection efficiency in any given year.

5.4.3 Corbicula Monitoring Program In 2010, five Corbicula (80 percent alive) were collected from the Unit I cooling tower basin during monthly reservoir sampling. No Corbiculawere collected in the scraping samples. The largest Corbiculacollected was retained in a sieve with a 3.35-4.74 mm length size range (Table 5.20 and Figure 5.5). Corbicula were collected in only form March through May. The mean density of live Corbicula in Unit 1 in 2010 was 22/m 2 . This was twice the density of Corbicula collected in Unit 1 in 2009 No sampling was conducted in October, because the Unit 1 Cooling 2010 Annual Environmental Report 16 FENOC (BVPS)

Tower could not be accessed due to unit shutdown.

In 2010, five Corbicula were collected from the Unit 2 cooling tower reservoir during monthly sampling (Table 5.21 and Figure 5.6). No Corbicula were collected in the scraping samples.

Three were live and two dead. The largest live Corbiculacollected was retained in a sieve with a 2.00-3.34 mm length size range. The mean density of live Corbicula in Unit 2 was 14/mr. This was an increase over 2009, when no Corbiculawere collected from Unit 2.

In 2010, BVPS continued its Corbiculacontrol program (Year 17), which included the use of a molluscicide (CT-1) to prevent the proliferation of Corbicula within BVPS. BVPS was granted permission by the Pennsylvania Department of Environmental Protection to use CT-1 to target the Unit 1 river water system and the Unit 2 service water system.

In 1990 through 1993, the molluscicide applications (CT-1) focused on reducing the Corbicula population throughout the entire river water system of each BVPS plant (Units 1 and 2). In 1994 and 1995, the CT-1 applications targeted the internal water systems; therefore, the CT-1 concentrations in the cooling towers were reduced during CT-1 applications. Consequently, adult and juvenile Corbicula in the cooling towers often survived the CT-1 applications.

Reservoir sediment samples taken after CT-I applications represent mortality of Corbicula in the cooling tower only and do not reflect mortality in BVPS internal water systems.

The monthly reservoir sediment samples collected in Units 1 and 2 Cooling Towers in recent years demonstrated that Corbicula were entering and colonizing the reservoirs. Overall, densities in Units 1 and 2 were somewhat less than those in 2008. The recent decrease of Corbicula at the BVPS returns densities to levels more consistent with densities in the Ohio River in the mid-1990's, but well below those present during the 1980's. Whether the increase in density of Corbicula in 2010 is indicative of increasing levels in the environment or due to sampling variability is uncertain, however, continued monitoring of Corbicula densities is recommended.

5.4.4 CorbiculaJuvenile Monitoring Program Figure 5.7 presents the abundance and size distribution data for samples collected in the Ohio River near the intake structure by petite ponar dredge in 2010. Six live individuals were collected in May, 17 in July, none in September, and four November for a total of 27 individuals.

They ranged in size from the 1.00-1.99mm size range that were spawned in 2010 to greater than 9.50 mm that were spawned in prior years. The number of individuals collected in 2010 was somewhat less than in 2009 (42 individuals), but comparable to or greater than in 2008 (23 individuals), 2007 (14 individuals), 2006 (three individuals) and 2005 (17 individuals).

A spring/early-summer spawning period typically occurs in the Ohio River near BVPS each year when preferred spawning temperatures (60-65' F) are reached (Figure .5.8). The offspring from this spawning event generally begin appearing in the sample collections in May. The settled clams generally increase in size throughout the year. The overall low numbers of live Corbicula collected in the sample collected outside the intake and cooling towers in 2010, compared to levels in the 1980's, likely reflects a natural decrease in the density of Corbicula in the Ohio 2010 Annual Environmental Report 17 FENOC (BVPS)

River near BVPS, although an increaseddensity of live individuals in the cooling towers may indicate that the population is beginning to increase again. Continued monitoring of Corbiculadensities is recommended.

5.4.5 Zebra Mussel Monitoring Program Zebra mussels (Dreissena polvmorpha) are exotic freshwater mollusks that have ventrally flattened shells generally marked with alternating dark and lighter bands. They are believed to have been introduced into North America through the ballast water of ocean-going cargo vessels probably from Eastern Europe. They were first identified in Lake St. Clair in 1988 and rapidly spread to other Great Lakes and the Mississippi River drainage system, becoming increasingly abundant in the lower, middle, and upper Ohio River. They use strong adhesive byssal threads, collectively referred to as the byssus, to attach themselves to any hard surfaces (e.g., intake pipes, cooling water intake systems, and other mussels). Responding to NRC Notice No. 89-76 (Biofouling Agent-Zebra Mussel, November 21, 1989), BVPS instituted a Zebra Mussel Monitoring Program in January 1990. Studies have been conducted each year since then.

3 Zebra mussels were detected in both pump samples (Figures 5.9 and 5.10) and substrate samples (Figure 5.11 and 5.12) in 2010. Zebra mussel veliger pump samples were collected from April i through October 2010 (Figures 5.9 and 5.10). Veligers were collected at all of the six sites that were sampled in 2010. At most sample sites, densities of veligers generally increased through the year, peaked in July and then were less for the balance of the sampling year. This seasonal pattern is typical for zebra mussels in the northeastern United States. Spawning begins as water temperature reach approximately 14 degrees C and peak at water temperatures of 21 degrees C.

Veligers densities usually peak about two weeks after the optimum water temperature for spawning is reached. Veliger densities then fall off as veligers mature and settle. The greatest density of veligers was present in the sample collected from the open waters of the Ohio River adjacent to the intake structure in July 2010 (256,800/mi3). This is among the highest density of zebra mussel veligers ever collected at BVPS. From May through September veligers were present in every sample collected at all locations. Overall, veliger densities in 2010 were greater than 2009. This is likely due to annual variability in numbers of veligers in the Ohio River.

In 2010, settled zebra mussels were collected only in scrape samples at the barge slip, and the intake structure (Figures 5.11 and 5.12). The highest density of settled mussels in any sample collected was at the barge slip (14 mussels/mi2) in May. The mussels collected at each of the sites included individuals that were capable of reproducing. The density of collected adult zebra mussels in 2010 was comparable to densities that occurred in 2008 and 2009.

Overall, both the number of observations and densities of settled mussels in 2010 were similar to those recorded in 2008 and 2009, which was somewhat higher than the preceding five years.

Although densities of settled mussels are low compared to other populations such as the Lower Great Lakes, densities comparable to those in the Ohio River are sufficient to cause problems in the operation of untreated cooling water intake systems. This was evidenced by the observation of a very high density of mussels found on BVPS's grizzly bars. Whether the population of 2010 Annual Environmental Report 18 i FENOC (BVPS)

I

zebra mussels in this reach of the Ohio River is resurging or only yearly fluctuations are present cannot be determined. In any case, the densities of mussels that presently exist are more than sufficient to impact the BVPS, if continued prudent monitoring and control activitiesare not conducted.

6.0 ZEBRA MUSSEL AND CORBICULA CONTROL ACTIVITIES I In 2010, BVPS continued its Corbicula and zebra mussel control program (17th year), which included the use of a molluscicide (CT-1) to prevent the proliferation of Corbiculawithin BVPS.

BVPS was granted permission by the Pennsylvania Department of Environmental Protection to I

use CT-I to target the Unit 1 river water system and the Unit 2 service water system.

In 1990 through 1993, the molluscicide applications (CT-1) focused on reducing the Corbicula I

population throughout the entire river water system of each BVPS plant (Units 1 and 2). In 1994 through 20010, the CT-i or 2 applications targeted zebra mussels and Corbicula in the internal water systems; therefore the molluscicide concentrations in the cooling towers were reduced I

during CT-I or 2 applications. Consequently, adult and juvenile Corbicula in the cooling towers often survived the applications. Reservoir sediment samples taken after CT-i or 2 applications represented mortality of Corbicula in the cooling tower only and do not reflect mortality in I

BVPS internal water systems.

In addition to clamicide treatments, preventive measures were taken that included quarterly I

cleaning of the intake bays. The bay cleanings are intended to minimize the accumulation and growth of mussels within the bays. This practice prevents creating an uncontrolled internal colonization habitat.
