1.2

SUMMARY

AND CONCLUSIONS There were no significant environmental events during 2004. One oil release occurred that, though reported to the Pennsylvania Department of Environmental Protection (PA DEP), caused no significant impact to the environment, and is detailed in Section 4.0 of this report..

2004 Aimual Environmental Report FENOC (BVPS)

During 2004, 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 programsdid not indicate any adverse environmentalimpactsfrom station operation.

1.3 ANALYSIS OF SIGNIFICANT ENVIRONMENTAL CHANGE During 2004, no significant changes to were made at BVPS to cause significant negative affect on the environment.

1.4 AQUATIC MONITORING PROGRAM The 2004 Beaver Valley Power Station (BVPS) Units I 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 29th year of operational environmental monitoring for Unit I and the 18th for Unit 2. As in previous years, the results of the program did not indicate any adverse environmental impact to the aquatic life in the Ohio River associated with the operation of BVPS.

The results of the 2004 benthic macroinvertebrate survey conducted in May and September indicated a normal community structure existed in the Ohio River both upstream and downstream of the BVPS. These benthic surveys are also a continuation of a Fate and Effects Study conducted from 1990 through 1992 for PA DEP to assess the ecosystem impacts of molluscicides 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 bcnthic 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. Soft muck-type substrate along the shoreline found in 2004 and previous years was conducive to segmented worm (oligochaete) and midge (chironomid) proliferation. In 2004, 59 macroinvertebrate taxa were identified Six new taxa (one mayfly, one stone-fly, one beetle and three snail taxa) were added to the cumulative list of benthic macroinvertebratescollected nearBVPS since the inception of thisprogram. In May, chironomids were the most frequently collected, while oligochetes were the most frequently collected groups in September. There were no major differences in the community structure between control and non-controlstations that 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.

The fish community of the Ohio River near the BVPS was sampled in May, July, September and November of 2004 with night electrofishing and daytime seining. Results from the 2004 fish surveys indicated that a normal community structure for the Ohio River existed near BVPS based 2004 Annual Environmental Report 2 FENOC (BVPS)

on species composition and relative abundance. 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.

During the survey, forage species were collected or observed in the highest numbers, principally emerald shiner, and gizzard shad. This indicated'a healthy fish co mmunity,'since game species rely on the availability of abundant forage for survival. Black buffalo, golden redhorse, and freshwater drum were 'also commonly'collected'in 2004. Variations inthe annual catch were probably attributable to normal fluctuations in the population size of the forage species and the predator populations that depend on them` Forage species, such as gizzard shad and emerald shiners, which have high reproductive potential, frequently respond to changes in the environment with large fluctuations in population size. This in turn influences the population of predator species.

The catch per unit effort (number of fish per minute) for electrofishing sampling in 2004 was 1.28 fish, which was the same as in 2003 and slightly lower compared with results of 2002 when electrofishing resulted in 1.98 fish collected per minute. These differences may have been the result of population changes, 'differences in sanipling schedule, or caused by. environmental conditions (e.g.' turbidity, waves, water temperature, flow) on specific electrofishing sampling dates that affected fish distribution or collection gear efficiency.

Little difference in the species composition of the catch was observed between the control

'(Station- 1) and non-control (Stations"2A,' 2B and 3) collections; Habitat preference and availability were probably the most' important factors affecting where and when fish were collected. In 2004, there was no indication of negative impact to thefish community in the Ohio Riverfrom the operation ofBVPS.

The monthly reservoir ponar samples collected in Units I and 2 cooling towers and the intake during 2004 indicated that Corbicula were entering and colonizing the reservoirs. Overall, the numbers of Corbicula collected in the samples were comparatively low, which continued the trend over the past few years of fewer Corbicula and reflected a water-body-wide trend observed in the Ohio River.

Since 1991, zebra mussels progressively moved upstream in'the Ohio River'. In 1993, zebra mussels were identified 50 miles downstream of BVPS. -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. Densities were generally low. During 1997, zebra mussel veligers, juveniles and adults were observed for the first time in sample collections. Densities of zebra mussels in samples increased significantly in 1998 and 1999.>' -

Overall, both the number of observations of settled mussels and the densities of veligers at BVPS in 2004 were lower than in 2003.-This could have been due to the cooler, and wetter than average summer. A similar reduction was observed in other watersheds in the Northeast. It is likely that densities of mussels will rebound in 2005 if temperature and precipitation return to normal, so BVPS should maintain their diligent zebra mussel monitoring and control program.

As in previous years, results of the BVPS environmental programs did not indicate any 2004 Annual Environmental Report 3 FENOC (BVPS)

adverse environmentalimpactsfrom station operation.

2.0 ENVIRONMENTAL PROTECTION PLAN NON-COMPLIANCES There were no Environmental Protection Plan non-compliances identified in 2004.

3.0 CHANGES INVOLVING UNREVIEWED ENVIRONMENTAL QUESTIONS No Unreviewed Environmental Questions were identified in 2004. Therefore, there were no changes involving an Unreviewed Environmental Question.

4.0 NONROUTINE ENVIRONMENTAL REPORTS During 2004, BVPS made one non-routine environmental report and required associated follow-up report to the Pennsylvania Department of Environmental Protection (PA DEP).

NOTE 1: Required reports under the National Pollutants Discharge Elimination System (NPDES) are not included in this section. They are included with the applicable submittal of the monthly Discharge Monitoring Reports (DMR). Copies of DMRs and attached reports are submitted to the USNRC, and are, therefore, not included in this report.

Note 2: On January 19, 2004, BVPS submitted an application to amend NPDES Permit No. PA0025615 to the PA DEP under Letter No. L-03-195. A copy was submitted to the USNRC.

4.1 Damaged Fuel Line for a Regulated Tank Causes Oil Contaminated Soil:

On July 22, 2004, a damaged fuel vent/retum line for the BVPS Emergency Response Facility (ERF) emergency diesel generator underground storage tank was discovered to have contaminated soil during excavation for the site security perimeter expansion project. The requisite telephone notifications were made on the date of discovery. Immediate and interim actions were initiated, and the follow-up written report was submitted in accordance with 25 PA Code § 245.305(d) under Letter No. L 10.

The investigation was initiated under BV-CR-04-05874. The site was controlled, recovered, clean up, and approximately 10 cubic yards of oil contaminated was removed and disposed in accordance with PA DEP regulations. The fuel line repairs were made and tested by a PA DEP certified tank handler. A Site Characterization Report, required in 25 PA Code § 245.309, was submitted on November 5, 2004 under Letter No. L-04-146 documenting the recovery and confirmatory measures taken.

5.0 AQUATIC MONITORING PROGRAM

5.1 INTRODUCTION

This section of the report summarizes the Non-Radiological Environmental Program conducted for the Beaver Valley Power Station I (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 xstudies 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.

5.1.1 Objectives of the Program The objectives of the 2004 environmental program were:

(1) To monitor for any possible environmental impact of BVPS operation on the benthic macroinvertebrate and fish communities in the Ohio River, (2) To provide a low level sampling program to continue an uninterrupted environmental database for the Ohio River near BVPS, pre-operational to present; and (3) To evaluate the presence, growth, and reproduction of macrofouling Corbicula(Asiatic clam) and zebra mussels (Dreissenaspp.) at BVPS.

5.1.2 Scope of Services Stantec Consulting Services Inc. (Stantec' was contracted to' perform the 2004 Aquatic Monitoring Program as specified in BVBP-ENV-001 - Aquatic Monitoring (procedural guide).

This 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 below.

2004 Annual Environmental Report 5 FENOC (BVPS)

5.1.3 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, 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. This sampling was conducted in May and September 2004. For each 2004 field effort, 18 benthic samples were collected and processed in the laboratory. All field procedures and data analyses were conducted in accordance with the procedural guide.

5.1.4 Fish Mionitoring The fish monitoring program consisted of seasonal sampling (May, July, September, and November) using boat electrofishing and seining techniques. Boat electrofishing was conducted at night along both shorelines at Stations 1, 2A, 2B, and 3 (Figure 5.3). Seining occurred at Stations I and 211 during the day and generally was performed in late afternoon or early evening.

All field procedures and data analysis were conducted in accordance with the procedural guide.

5.1.5 Larval Cages/Zebra Mussel Scraper/Bridal Veil Samplers/Pump/Biobox Sampling Larval cages (two long term and two short term) were set in the project intake structure to sample for Corbicula beginning in 1996. The cages continued to be used to monitor for Corbicula through August 1997. Results from a study conducted from April through June 1997 to compare short-term larval cage and petite Ponar sample results indicated that Ponar sampling provided comparable results to short-term larval cages for monthly sampling. In August 1997, Ponar sampling replaced short-term larval cage sampling. Long-term cages were used until May 1998 when all larval cages were removed. After September 11, 2001, access was restricted to the project intake structure. BVPS elected to sample for corbicula by collecting bottom sediment from the Ohio River outside the intake structure in conjunction with the fish monitory program.

A petite Ponar Dredge was used to collect the samples.

Wall scraping samples were collected monthly from the Unit I cooling tower, the Unit 2 cooling tower, the barge slip, and the intake wall in 1996 and 1997. Wall scrapings were taken with a D-frame scraper, with five scrapes of approximately 2 ft each made per sample at the sampling locations. In 1998, two additional locations were added; the emergency outfall (June through November) and the emergency outfall impact basin (August through November). In 1999 through 2004, these added sites were sampled from March through November.

The intake sampling and wall scraping sampling was historically conducted once per month, 2004 Annual Environmental Report 6 FENOC (BVPS)

yearlong. Beginning in December 1997, it was decided to forego sampling in December and January of each year, since buildup of the target organisms, Corbicula and zebra mussels, does not occur in these cold water months. Monthly sampling has been maintained throughout the balance of the year.

A pump sample for zebra mussel veligers was collected at the barge slip location monthly from April -througl 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 tower of Unit ' and Unit 2 in October 1998. At the request 'of BVPS, sampling was extended through'November in 1998. In' 2004,' these additional locations were sampled from March through October. In 2004, to' monitor for settlement, a bridal veil sampler was deployed tat the barge slip' and monitored monthly (March through November) for zebra mussels.

In April 1998, a biobox was set up at the emergency outfall basin to monitor for settling zebra mussels. The biobox was checked each month, and four substrate plates were removed and analyzed in November 1998. In 2001, the biobox set up at the emergency outfall basin was replaced with two more efficient aquarium style bioboxes. These bioboxes continued to be used at this location through 2002. The bioboxes were also used to determine the efficacy of the periodic'tricatments to control zebra mussel'and Corbicula in the facility. In 2004 the bioboxes were"'used during zebra mussel and Corbicula treatments to monitor the treatment's efficacy only.

5.1.6 CorbiculalZebraMussel Density Determinations During the scheduled shutdown period for each unit, 'each cooling tower reservoir bottom was sampled by petite Ponar at standardized locations within the reservoir. Counts of live and dead clams and determination of density were made.

During all Corbiculalzebramussel sampling activities, observations were made of the shoreline and other adjoining hard substrates for the presence of macrofouling species.

5.1.7 Monthly Activity Reports Each month activity reports that summarized the activities that took place the previous month were prepared. The reports included the results of the monthly Corbiculalzebra 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.

5.1.8 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 5.4 is a plan view of BVPS. The site is approximately I mile (1.6 km) from Midland, Pennsylvania; 5 miles (8 km) 2004 Annual Environmental Report 7 FENOC (BVPS)

from East Liverpool, Ohio; and 25 miles (40 km) from Pittsburgh, Pennsylvania. The population within a 5-mile (8 kim) radius of the plant is approximately 18,000. The Borough of Midland, Pennsylvania has a population of approximately 3,500.

The site lies along the Ohio River in a valley, which has a gradual slope that extends from the river (Elevation 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.

The station is situated on the Ohio River at River Mile 34.8 (Latitude: 40° 37' 18"; Longitude:

800 26' 02") at a location on the New Cumberland Pool that is 3.3 river miles (5.3 km) downstream from Montgomery Lock and Dam and 19.4 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.

Ohio River water temperatures generally vary from 321F to 841F (00 C to 290 C). Minimum and maximum temperatures generally occur in January and July/August, respectively.

BVPS Units I and 2 have a thermal rating of 2,689 megawatts (MW). Units I & 2 have a design electrical rating of 835 MW and 836 MW, respectively. The circulating water systems for each unit 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 1 began in 1976 and Unit 2 began operation in 1987.

5.2 Results Aquatic Monitoring Program The environmental study area, established to assess potential impacts, 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 mile (0.5 km) upstream of BVPS and is the control station. Station 2A is located approximately 0.5 mile (0.8 kln) downstream of the BVPS discharge structure in the main channel. Station 2B is located in the back channel of Phillis Island, also 0.5 mile downstream of the BVPS discharge structure. Station 2B is the principal non-control station because the majority of discharges from BVPS Units I and 2 are released to this back channel.

Station 3 is located approximately two miles (3.2 kln) downstream of BVPS.

Sampling dates for each of the program elements are presented in Table 5.1.

The following sections summarize the findings for each of the program elements.

5.2.1 Benthic Macroinvertebrate Monitoring Program 5.2.1.1 Objectives: The objectives of the benthic surveys were to characterize the benthic macroinvertebrates of the Ohio River near BVPS and to determine the impacts, if any, of BVPS operations.

2004 Annual Environmental Report 8 FENOC (BVPS)

5.2.1.2 Methods: Benthic surveys were scheduled and performed in May and September 2004. Benthic samples were collected at Stations 1, 2A, 2B, and 3 (Figure 5.2), using a petite Ponar grab sampler. 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. rcspectively).

The contents of each grab were gently washed through a U.S. Standard No.'30 sieve and the retaincd contents were placed in a labeled bottle and preserved in ethanol. In the laboratory, rose bengal stain was added to aid in sorting band identifying :the, benthic organisms.

Macroinvertebrates were sorted from each sample, identified to the lowest taxon practical and counted. Mean density (number/m2) 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.

5.2.1.3 Habitats: Substrate type is an important factor in determining the composition of the benthic community. Two distinct benthic habitats exist in the Ohio River near BVPS. These habitats are the'result of damming, channelization, and river traffic. During sampling, shoreline habitats were geeirllysoft muck substrates composed of sand, silt, and detritus. An exception occurred along the north shoreline of Phillisilsland at Station 2A where clay and 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 is probably the result of channelization and scouring by river currents.

5.2.1.4 Overall Results: Fifty-nine (59) macroinvertebrate taxa were identified during the 2004 monitoring .program (Tables 5.2, 5.3.1 and 5.3.2). A mean' density -of 3,297 macroinvertebateslm2 was collected in May and 5,977/m2 in September (Table 5.4). 'As in previous years, the macroinvcrtebrate assemblage during 2004 was dominated by' burrowing organisms typical of soft unconsolidated substrates. Oligochaetes (segmented worms), mollusks (clams and snails) and chironomid (midge fly) larvae were abundant (Table 5.4). '

Thirty-seven (37) taxa were present in the May samples,'and forty-one (41) taxa in the September samples (Table 5.3.1 and 5.3.2). Nineteen (19) of the 59 taxa were present in both May and September. - -

The Asiatic clam (Corbicula sp.) 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 1997-2004 sampling programs (see Sections 5.2.4 Zebra Mussel Monitoring Program). Both species were collected in benthic macroinvertebrate samples in 2004. -

In 2004, six taxa were added to the cumulative taxa list of macroinvertebrates collected near 2004 Annual Environmental Report 9 FENOC (BVPS)

BVPS (Table 5.2). One was a mayfly (emphemeropteran), one was a stonefly (plecopteran), one was an aquatic beetle (coleopteran), and three were snails (gastropods). No state or Federal threatened or endangered macroinvertebrate species were collected during 2004.

5.2.1.5 Community Structure and Spatial Distribution: In May 2004 samples, chironomids accounted for the highest mean density of macroinvertebrates and oligochaetes had the second highest (1,591/m2 or 48.3 percent of the total density and 1,183/m2 or 35.9 percent, respectively) (Table 5.4). Mollusks had the third highest mean density in May 2004 (279/m2 or 8.5 percent of the total density) while organisms other then oligochaetes, chironomids and mollusks had the fourth highest mean density (243/m2 or 7.4 percent of the total).

In September 2004, samples oligochaetes accounted for the highest mean density of macroinvertebrates and chironomids had the second highest (3,383/m2 or 56.6 percent of the total density and 1,520/m2 or 25.4 percent, respectively) (Table 5.4). Mollusks had the third highest mean density in September 2004 (774/m2 or 12.9 percent) while the "others" category had the fourth highest mean density (301/m2 or 5.0 percent).

In May, the highest density of macroinvertebrates (8,385 organisms/m2) occurred at Station 2B11.

In September, the highest density of macroinvertebrates occurred at Station 2B3 (11,825/ m2).

The both May and September the lowest mean density of organisms occurred at Station 2A (645/m2 and 1,075/m2, respectively).

5.2.1.6 Comparison of Control and Non-Control Stations: For this analysis, 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 2B1, 2B2, and 2B3) the non-control station, since it is the station subjected to BVPS's discharge most regularly. 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 higher (4,737/m2) than that of the control station (2,7521m2) in May (Table 5.5). The density of oligochaetes was about 1.5 times higher at the control station (1,419/m2) than at the non-control station (1,032/m3).

Conversely, chironomids were present at a much greater density at the non-control stations (2,895/m2 or 61 percent of the total density) than at the control station (473/m2 or 17 percent).

Mollusks were present at greater densities at the non-control stations (444/m2) than at the control station (602/m2), although mollusks contributed to approximately 9 percent of the to density of macroinvertebrate in the control and in non-control stations. These 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 was higher at the control (10,062/m2) than at the non-control station (7,683/m2). The density of macroinvertebrates in both the control and non-control stations was higher in September than in May. Oligochaetes, mollusks, and "others" occurred at higher densities at the control than the non-control stations. Chironomids 2004 Annual Environmental Report 10 FENOC (BVPS)

I were present at higher densities at the non-control station than the control station. As in May, the differences observed between Station I (control) and Station 2B (non-control) were probably related to observed differences in habitat at each station. Differences were within the expected range of variation for natural populations of macroinvertebrates.

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 Shanon-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 one, 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 In May the diversity, evenness and richness indices were somewhat higher in the control station (Station 1) than in then'non-control stations (2B1, 2B2, 2B3) although the number of taxa present was'c'omparable (Table '5.6). In September, the number of taxa, and the diversity and richness indices were greater in the control station than any of the non-control stations." The evenness at the control station' was greater than at 'two of the' three non-control stations. In past years, including 2003, these community indices were higher, (indicative of a healthier community), in the non-control stations than the control station. The differences in the various indices in 2004 and variations between years were within the 'range that would normally be present in a waterbody such as the Ohio River. '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.

5.2.1.7 Seasonal Comparison: The density of benthic organisms observed was about three times lower in May 2004 than in September 2004 (Table 5.3.1 and 5.3.2). Thirty-seven (37) taxa were identified in May, and 41 in September. Chironomids were the most commonly collected macroinvertebrates in May and 'oligochaetes were'the most common in September.

The Shannon-Weiner diversity indices in'May 2003 collections ranged from 0.44 at Station 2B1 to 1.04 at Station 1 (Table 5.6). 'In'May evenness ranged from 0.37 at-Station 2B1 to 0.98 at Station 2A.'Richness was greatest at Station 1 (3.37) and lowest at Station'2B2 (2.56). The diversity of the macroinvertebrate community' in September was generally comparable to that in May. Diversity ranged from 0.59 at Station 2B3 to 1.06 at Station 1. Evenness was also comparable in September to May and ranged from '0.47 at' Station 2B3 to '0.83 at Station 2A.

Richness was'greatest at Station 1 (5.68) and lowest at Station 3 (2.18). -

5.2.1.8 Discussion: Substrate was probably the most important factor controlling the distribution and abundance of the benthic macroinvertebrates in the Ohio River near BVPS. Soft, mucky substrates that 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 2004 fell within the range of densities' 2004 Annual Environmental Report 1.

FENOC (BVPS)

of macroinvertebrate collected at BVPS in previous years (Table 5.7). The introduction of zebra mussels and Corbicula into the Ohio River may impact the benthic community structure.

However, the community structure has changed little since pre-operationalyears, and the available evidence does not indicate that BVPS operations have affected the benthic community of the Ohio River).

5.2.2 Fish Sampling Program 5.2.2.1 Objectives Fish sampling was conducted in 2004 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.

5.2.2.2 Methods Adult fish surveys were scheduled and performed in May, July, September, and November 2004.

During each survey, fish were sampled by standardized electrofishing techniques at four stations (Stations 1, 2A, 2B and 3) (Figure 5.3). Seining was performed at Station 1 (north shore) and Station 2B (south shore of Phillis Island), to sample species that are generally under-represented in clectrofishing catches (e.g., young-of-the-year fish and small cyprinids).

Night clectrofishing was conducted using a boom electroshocker and floodlights mounted to the bow of the boat. A Coffelt variable voltage, pulsed-DC electrofishing unit powered by a 3.5-kW generator was used. The voltage selected depended on water conductivity and was adjusted based on the amperage of the current passing 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 I (control) and Station 2B (non-control) during each scheduled 2004 BVPS fishery survey. 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 I (north shore) and Station 2B (south shore of Phillis Island) during each survey.

Fish collected during electrofishing and seining efforts were processed according to standardized procedures. All captured game fishes were identified, counted, measured for total length (nearest 1 mm), and weighed (nearest I g). Non-game fishes were counted, and a random subsample of lengths was taken. Live fish were returned to the river immediately after processing was 2004 Annual Environmental Report 12 FENOC (BVPS)

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 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. - -

5.2.2.3 Overall Results Fish population surveys have been conducted in the Ohio River near BVPS annually from 1970 through 2004. These surveys have resulted in the collection of 73 fish species and five different hybrids (Table 5.8).

In 2004, 342 fishes representing 21 taxa were collected (i.e., handled) during BVPS surveys by electrofishing and seining (Tables 5.9 and 5.10). All taxa collected in 2004 were previously encountered at BVPS. An estimated additional several hundred individuals were observed but not handled during electrofishing surveys (Table 5.15). The most.common species in the 2004 BVPS surveys, collected by electrofishing and seining combined, were emerald shiner (23.1 percent of the total catch), freshwater drum (13.7 percent), golden redhorse (11.7 percent), and black buffalo (9.4 percent). The remaining 17 species combined accounted for 42.1 percent of the total handled catch. The most frequently observed (handled and not handled combined) fish in 2004 were gizzard shad (Tables 5.9, 5.10, and 5.15). Game fishes collected during 2004 included channel catfish, flathead catfish, white catfish, white bass, bluegill, smallmouth bass, sauger, wallcye, and striped bass hybrid. Game fishes represented 17.3 percent of the total handled catch, 5.0 percent of which were walleye.

A total of 208 fish, representing 20 taxa, was collected by electrofishing in 2004 (Table 5.9).

Golden redhorsc and black buffalo accounted for the largest portion of the 2004 electrofishing catch (19.2 percent and 15.4, respectively) followed by shorthead redhorse sucker (11.1 percent)..

Walleye, the most abundant gasne species collected in electrofishing efforts, was the next most abundant species (8.2 percent). None of the other species collected contributed to greater than seven (7) percent of the total catch.

A total of 134 fish representing 9 taxa was collected by seining in 2004 (Table 5.10). The most abundant taxa collected were emerald shiner (58.2 percent of the total catch), freshwater drum (26.9 percent), and gizzard shad (8.2 percent). The game species collected by seining were white bass, bluegill, smallmouth bass and striped bass hybrid.

A total of71 fish representing 18 species was captured during the May 2004 sample event (Table 5.11). A total of 70 fish was collected during electrofishing and I during seine netting. Golden redhorse (22.9 percent ofjthe total catch) shorthead redhorse sucker (14.3 percent and black buffalo (10.0 percent) were the most common species boated during the electrofishing effort.

Channel catfish (8.6 percent of the total catch) was the most abundant game species collected in May. One emerald shiner was the only fish collected during the seining effort.:

A total of 81 fish representing 16 species was captured during the July 2004 sample event (Table 2004 Afinual Environmental Report 13 FENOC (BVPS)

5.12). A total of 39 fish was collected during electrofishing and 42 during seining. Golden redhorse and black buffalo were the most common species boated during the electrofishing effort and each represented 17.9 percent of the total catch. Channel catfish were the most abundantt game species in July (7.7 percent of the total catch). Gizzard shad (76.2 percent of the total catch) was the most frequently collected species during the seining efforts.

During the September sample event, 73 fish representing 14 taxa were collected (Table 5.13). A total of 30 fish was collected during electrofishing and 43 during seining. Golden redhorse (30.0 percent of the total catch), sauger (16.7 percent), walleye (13.3 percent) and freshwater drum (13.3 percent) were the most common species boated during the electrofishing effort. Sauger, walleye, and smallmouth bass were the game species collected during electrofishing efforts in September. Emerald shiner (51.2 percent) and gizzard shad (25.6 percent) were the most commonly collected species collected in seining in September. A white bass, a bluegill and a smallmouth bass were the game species collected by seines.

During the November sample event, 117 fish representing 14 taxa were captured (Table 5.14). A total of 69 fish were collected during electrofishing and 48 during seining. Black buffalo (24.6 percent of the total catch), walleye (14.5), shorthead redhorse sucker (11.6 percent), and golden redhorse (11.6 percent) were the most common species boated during the electrofishing effort.

Except for one striped bass hybrid, emerald shiner (97.9 percent of the total catch) was the only species collected during the seining efforts in November.

At the request of the Pennsylvania Fish and Boat Commission (PFBC), electrofishing catch rates were calculated as fish per minute (i.e., power on time) of sampling for 2002 through 2004.

Electrofishing catch rates are presented in Tables 5.16, 5.17, and 5.18 for fish that were boated and handled during the 2002 through 2004 surveys by season. The annual catch rates were consistent over the three years. Also in each year the lowest catch rate was in summer, which was not unexpected since larger fish that are more susceptible to electrofishing tend to be more offshore in the summer.

In 2004, the annual catch rate was 1.28 fish per minute. The greatest catch rate occurred in May (spring) (1.72 fish per minute). The lowest catch rate occurred in September (fall) with a rate of 0.74 fish per minute.

In 2003, the annual catch rate was 1.28 fish per minute. The greatest catch rate in 2003 occurred in November (winter) (2.12 fish/ electrofishing minute). A large number of shorthead redhorse, freshwater drum, and golden redhorse contributed to this total. The lowest catch rate occurred in September (fall) with a rate of 0.77 fish/ electrofishing minute.

In 2002, the annual catch rate was 1.98 fish per minute. The greatest catch rate in 2002 occurred in November (winter)(3.63 fish/electrofishing minute). This was the highest seasonal catch rate of the three years that were compared. A large number of gizzard shad contributed to this total.

The lowest catch rate occurred in July (summer) with a rate of 1.08 fish/electrofishing minute.

I 5.2.2.4 Comparison of Control and Non-Control Stations 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 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).

The seine data for 2004 (Table 5.10) indicated no. major differences in species composition between control and non-control stations. Emerald shiner was the most abundant species at both locations. The total number of fish captured at the non-control station was larger than at the control station.

5.2.2.5 Discussion 7he results of the 2004 fish surveys indicated that there is a normal community structure in the Ohio River in the vicinity ofBVPS based on species composition and relative abundance offish observed during the surveys Forage species were collected in the highest numbers.

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 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, which could be the reason for the large numbers of emerald shiners observed in 2004. 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 clectrofishing efforts in some years can decrease the collection efficiency of this gear.

In 2004, species composition remained comparable among stations. Common taxa collected in the 2004 surveys by all methods included black buffalo, emerald shiner, redhorse sucker species, sauger, quillback, and walleye. Little difference in the species composition of.the catch was observed between the control (i) and non-control stations (2A, 2B and 3). Habitat preference and availability were probably the most important factors affecting where and when different species of fish are collected.

2004 Annual Environmental Report 15 FENOC (BVPS)

5.2.3 Corbicula Monitoring Program 5.2.3.1 Introduction The introduced Asiatic clam (Corbiculafluminea) was first detected in the United States in 1938 in the Columbia River near Knappton, Washington (Burch 1944). It has since spread throughout most of the country, inhabiting any suitable freshwater habitat. Information from prior aquatic surveys has demonstrated the presence of Corbicula in the Ohio River in the vicinity of the BVPS, and the plant is listed in NUREG/CR4233 (Counts 1985).

One adult Asiatic clam is capable of producing many thousands of young called early juveniles.

These early juveniles are very small (approximately 0.2 mm) and will easily pass through the water passages of a power plant. Once the juveniles settle on the substrate, rapid growth occurs.

If Corbicula develop within a power plant's water passages, they can impede the flow of water through the plant, especially through blockage of condenser tubes and small service water piping.

Reduction of flow may be so severe that a plant shutdown is necessary. Corbicula are of particular concern when they develop undetected in emergency systems where the flow of water is not constant (NRC, IE Bulletin 81-03).

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). This report describes this Monitoring Program and the results of the field and plant surveys conducted in 2003.

5.2.3.2 Corbicula Monitoring 5.2.3.2.1 Objectives: 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 5.2.4).

5.23.2.2 Methods: Cooling Towers - Monthly Reservoir Sampling 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 I 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.

In 2004, once each month (March through November), a single petite ponar grab sample was scheduled to be taken in the reservoir of each cooling tower to obtain density and growth information on Corbicula present in the bottom sediment. Due to unit outage, no samples were collected from Unit I during October or November. The samples collected from each cooling tower were returned to the laboratory and processed. Samples were individually washed, and any 2004 Annual Environmental Report 16 FENOC (BVPS)

I 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.'

Cooling Towers CorbiculaDensity Determination Population surveys of both BVPS cooling tower reservoirs have been conducted during scheduled outages (1986 through 2004) to-estimate the number of.Corbicula present in these structures. Unit I was sampled in October 2004.

5.2.3.2t3 Results:

Unit I Cooling Tower - Monthly Reservoir Sampling In 2004, 137 Corbicula (65.6 percent alive) were collected from the Unit I cooling tower basin during monthly reservoir sampling. The largest live Corbicula collected was retained in a sieve with a 6.30-9.49 mm length size range (Table 5.19 and Figure 5.5). The greatest numbers of Corbiculawere collected in May (61 individuals). Corbiculawere collected in lower numbers in the other months sampled. Scheduled collections were not made in October or November because of unit outage.

Unit 2 Cooling Tower - Monthly Reservoir Samnpling In 2004, 55 Corbicula (81.8 percent alive) were collected from the Unit 2 cooling tower reservoir during monthly sampling. The largest live Corbicula collected was within the 3.354.74 mm length size range (Table 5.20 and Figure 5.6). Individuals were collected from March through Novenber. The greatest number of Corbicula (29 individuals) were collected in March.

In 2004, BVPS continued its Corbicula control program (Year 15), which included the use of a molluscicide to control Corbicula within BVPS.

In 1990 through -1993, the molluscicide applications 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 applications targeted the internal water systems; therefore, the concentrations in the cooling towers were reduced during the new control application process. Consequently, adult and juvenile Corbicula in the cooling towers often survived treatment. - Reservoir- sediment samples taken after treatment represent mortality of Corbicula'in the cooling tower only and do not reflect mortality in BVPS internal water systems. In 2004, clamicide treatment occurred on April 27, May 15, July 20, August 4, October 13, and November 19 for Unit I and May 4, May 18, July 27, August I0, October 19, and November 2 for Unit 2.'

2004 Annual Environmental Report 17 FENOC (BVPS)

Population surveys of both BVPS cooling tower reservoirs were scheduled to be conducted during scheduled outages (1986 through 2004) to estimate the number of Corbicula present in these structures. A population survey of Unit I Cooling Tower was conducted on October 20, 2004 during a scheduled unit outage, 58 Corbicula (98.3 percent alive) were collected from the Unit I cooling tower basin during the October outage sampling. The largest clam collected was in the 9.50-12.50 mm length size range (Figure 5.6A). The estimated number of live Corbicula in the Unit I Cooling Reservoir was 1,857,973, which was significantly less than previous years.

5.2.3.2.4 Discussion: The monthly reservoir sediment samples collected in Units I and 2 cooling towers during 2004 demonstrated that Corbicula were entering and colonizing the reservoirs. Overall, densities in Unit I were similar to that in 2003 and in Unit 2 densities were somewhat less than in 2003. The maximum monthly density of Corbicula in Unit I was 2580/M2 , which occurred in May. The maximum density of clams in Unit 2 was 1075/M2 , which occurred in March. 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.

5.2.3.3 Corbicula Juvenile Study:

5.233.1 Objectives The Corbiculajuvenile study was designed to collect data on Corbicula spawning activities and growth of individuals entering the intake from the Ohio River.

5.233.2 Methods Specially constructed clam cages were initially utilized for this study. Each cage was constructed of a I-ft durable plastic frame with fiberglass screening (1 mmn mesh) secured to cover all open areas. Each cage contained approximately 10 lbs of industrial glass beads (3/8-inch diameter) to provide ballast and a uniform substrate for the clams. The clam cage mesh size permitted only very small clams to enter and colonize the cage.

In 1988 through 1994, the cages were left in place for five months following initial placement.

Changes in procedure were made to better define the time period when Corbiculawere spawning in the Ohio River and releasing larvae that could enter BVPS through the intake structure.

Larval cages were maintained in the BVPS intake structure in 1995 according to the following procedure. Each month, two empty clam cages were placed in the intake structure bays. Each cage was left in place for two months, after which time it was removed and examined for clams.

Four clam cages were maintained in the intake structure bays each month throughout 1995-1996.

In February 1996, it was decided to modify the sampling regime so that two of the four cages in the forebay were long-term samplers and the other two were monthly short-term samplers. Each month, the two long-term samplers were pulled; the fine sediment was carefully washed from the cage and any Corbicula present were measured. The cages were immediately redeployed along with any identified Corbicula. The two short-term cages were pulled monthly and the contents 2004 Annual Environmental Report 18 FENOC (BVPS)

removed for laboratory analyses. New short-term cages were then deployed.

Each short-term clam cage removed after the one or two-month colonization period was returned to the laboratory where it was processed to determine the number of clams that had colonized the cage. Corbicila6btained from each cage were rinsed through a series of stacked U.S. Standard

,sieves ranging in mesh size from 9.5 mm to 0.6 mm." Live and dead clams on each sieve were counted and the numbers were 'recorded. 'Thel largest and smallest'clams 'were 'measured to establish a length range for the sarmple.- The size distribution data' obtained using the sieves reflected clam width, rather than length.

Observational-based concerns that the clam cages could quickly clog with sediment during high sediment periods and, as a result, not sample effectively, led to an evaluation of an' alternate sampling technique. From April through Juie'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.

During the 1998 sampling season, at the request of BVPS personnel,'all clam' cages were removed after the May 18, 1998 collection. Monthly petite ponar grabs from the forebay in the intake building 'continued thereafter. '

In 2002, the sampling with petite ponar was moved to the Ohio River directly in front of the Intake Structure Building. Collections were made in conjunction with the fisheries'sampling (May, July, September, and November). During each sampling month two ponar grabs were taken approximately 20 feet off shore of the intake building. These grab samples were processed in the same manner as when they were collected from within the Intake Structure Building.

5.2.3.3.3 Results Figure 5.7 presents the abundance and size distribution'data for samples collected in the Ohio River near the intake structure by petite ponar in 2004. Corbicula were collected only during July, and September. Only one individual was 'collected 'duiring each of these months. The number of individuals collected was reduced from the prior three years (14 in 2001, 25 in 2002, and 8 in 2003).

5.2.3.3.4 Discussion' 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 late-April (Figure 5.7). The settled clams generally increase in size throughout the year. The overall low numbers of live Corbicula collected in the intake and cooling towers in 2004, compared to levels in the 1980's, likely reflects a naturaldecrease in the density of Corbicula in the Ohio River near BVPS.

5.2.4 Zebra Mussel Monitoring Program 5.2.4.1 Introduction Zebra mussels (Dreissena volymorpha) 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.

Adult zebra mussels can live up to five years and grow to 2 inches in length. North American research suggests that each female may be capable of producing over one million microscopic (veliger larvae) offspring per year, which can easily pass through water intake screens. They use strong adhesive byssal threads, collectively referred to as the byssus, to attach themselves to any hard surfaces (e.g., boat hulls, intake pipes and other mussels). Transport of these organisms between water bodies is accomplished in part by boats that have adult mussels attached to their hulls or larvae in their live wells and/or bilges. In anticipation of zebra mussel infestation and responding to NRC Notice No. 89-76 (Biofouling Agent-Zebra Mussel, November 21, 1989),

BVPS instituted a Zebra Mussel Monitoring Program in January 1990.

The Zebra Mussel Monitoring Program included the Ohio River and the circulating river water system of the BVPS (intake structure and cooling towers). This section describes this Monitoring Program and the results obtained during Ohio River and BVPS surveys conducted through 2004.

5.2.4.2 Monitoring 5.2.4.2.1 Objectives: 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.

5.2.4.2.2 Methods:

Intake Structure and Barge Slip: The surveillance techniques used on site were:

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; 2004 Annual Environmental Report 20 FENOC (BVPS)

Pump sample collections from the barge slip'and outside the intake structure, to detect the planktonic early life forms (March through October); and

Sampling of an artificial substrate (bridal veil material) suspended in the'Ohio River from the Barge Slip (April through November).

Cooling Towers: The techniques used in the Unit I and Unit 2 cooling tower locations were:

Monthly 'reservoir scraper. sample collections in each cooling tower (March .through November); and

Pump samples in March through October to detect planktonic life forms.

Emergency Outfall: '

Monthly scraper sample collections in the emergency outfall impact basin (March through November);'and

Pump samples in'March through Octobler'to detect planktonic life forms.

Splash Pool:

Monthly scraper sample collections in the Splash Pool (March through November); and

Pump samples in March through October to detect planktonic life forms.

5.2.4.23 Results:

Zebra mussels were detected in both pump samples (Figures 5.9 and 5.10) and substrate samples' (Figure 5.11 and 5.12) in 2004.

2004 MAnial Environmental Report 21 FENOC (BVPS)

Zebra mussel veliger pump samples were collected from March through October 2004 (Figures 5.9 and 5.10). Densities of veligers generally peaked in July and August. The greatest density of veligers was present in the sample collected from the Unit I Cooling Tower Reservoir and in the slash pool in August (700/M3 ). Veligers were first present in samples collected in July Veligers were present in all samples collected in August. For September, veligers were found in five of the six collection locations. Overall, veliger densities were lower in 2004 than in 2003. In 2003, the greatest density collected was 52,560/M3 . Whether this was due to an overall decrease in numbers of veligers in the Ohio River in 2004 or due to the limited number of samples and the propensity of veligers to be non-uniformly distributed in the water is uncertain. Summer 2004 in the northeast was much wetter and cooler than average, which could have contributed to the relatively low densities of veligers present at BVPS. Lower than usual densities of veligers were observed in sampling conducted by this report's author in the Great Lakes, the Hudson River and the New York State Barge Canal System. It is expected that the density of veligers will rebound in 2005, if the summer is relatively drier and warmer.

In 2004, settled zebra mussels were collected in scrape samples only at the Barge Slip and the Intake Structure. Single individuals were collected at the Intake Structure in May and September and at the Barge Slip in May and November. None were collected at the Unit I Or Unit 2 Cooling Tower Reservoir, the Splash Pool, or the Emergency Outfall Impact Basin (Figures 5.11 and 5.12). The mussels collected at the Barge Slip and Intake Structure were adult mussels capable of reproducing. None were collected in the Bridal Veil Samplers deployed in the Barge slip in 2004 (Table 5.21). Compared with 2003, the collection of adult zebra mussels was lower compared to past years.

5.2.4.2.4 Discussion From 1991 through 1993, based on reports, zebra mussels moved progressively upstream from the lower to upper Ohio River. In 1994, there were confirmed zebra mussel sightings at locations both upstream and downstream of BVPS, including the Allegheny River. The July 1995 sighting of zebra mussels at Maxwell Lock and Dam on the Monongahela River established the presence of these organisms within the Allegheny, Monongahela and Ohio Rivers in Western Pennsylvania.

In 1995, live zebra mussels were found by divers in the BVPS main intake structure and auxiliary intake structure during scheduled cleaning operations. The 1996 Zebra Mussel Monitoring Program at BVPS did not collect any live zebra mussels at BVPS. During the first quarter 1996 (January and February) intake bay cleaning, divers observed an undetermined number of zebra mussels in the intake bays. During the second quarter 1996 cleaning, no mussels were reported.

During the third and fourth quarter 1996 intake bay cleanings, about one dozen mussels were observed each time in Bay C only. None were collected by the divers for confirmation.

During 1997, zebra mussel veligers were observed in June. Juvenile zebra mussels appeared in the clam cage and ponar dredge samples. In November 1997, adult zebra mussels were found in the intake ponar dredge samples.

2004 Annual Environmental Report 22 FENOC (BVPS)

During the 1998 Zebra Mussel Monitoring Program at BVPS, zebra mussel veligers.. juveniles, and an adult were observed in sample collections. tA moderate density of zebra mussel veligers was observed during the August through November 1998 samples, indicating that spawning occurred sometime during the late summer. Juvenile zebra mussels appeared during March sampling. These mussels were 3.5, 3.5, and 4.5.mrm in length, which indicates that they were probably young-of-the-year in 1997. Young-of-the-year zebra mussels appeared in September through November. This'observation confirms-successful zebra mussel spawning in the area around BVPS.

During 1998, zebra mussels were also found on the walls of the main intake structure during each of the quarterly inspections that took place. During the first quarter, greater than 100 zebra mussels/ft2 were present in Bay B, although fewer were present in the other bays. Less than 5 mussels/ft2 were observed during the second quarter inspection that took place in April. Only Bays A and B were inspected, however. A few small zebra mussels were observed during the third quarter inspection; however, any recently settled mussels would be easily missed during a visual inspection. 'Few (>1 O/ft2 ) mussels were also observed during the fourth quarter inspection.

Corbicula were also present in the main intake structure during each quarterly inspection. Zebra mussels were also observed in low densities in the alternate intake structure during the last three quarters of 1998.

In 1999, the number of both veligers and settled zebra mussel increased significantly in the Ohio River near the BVPS. For the first time, the settled zebra mussels were collected in groups rather than as individuals. The density of veligers exceeded 1000/M3 on many occasions for the first time in 1999.

Overall, both the number of observations of settled mussels were similar in 2003 and 2002. The density of veligers was less in 2002 than 2003 but similar to 2001. Densities, however, remained high compared to past years.

In 2004 the density of veligers and settled mussels was lower than the prior three years. Zebra mussels densities in other water systems display significant annual variations due to environmental variables including water temperature and flow conditions. The atypically cooler and wetter summer in 2004 could have contributed to the lower numbers of zebra mussels observed. Whether the population of zebra mussels in this reach of the Ohio River is plateauing and only yearly fluctuations arepresent cannot be determined.In any case, the densities of mussels that presently exist are more than sufficient to impact the BVPS, if continuedprudent monitoringand controlactivitiesare not conducted.

5.2.5 Zebra Mussel and Corbicula Control Activities In 2004, BVPS continued its Corbicula and zebra mussel control program (thirteenth year),

which included the use of a molluscicide to prevent the proliferation of Corbiculawithin BVPS.

In 1990 through 1993, the molluscicide applications focused on reducing the Corbicula population throughout the entire river water system of each BVPS plant (Units I and 2). In 1994 2004 Annual Environmental Report 23 FENOC (BVPS)

_______________ __________________ ______________J through 2004, the treatments targeted zebra mussels and Corbicula in the internal water systems; therefore the molluscicide concentrations in the cooling towers were reduced. Consequently, adult and juvenile Corbicula in the cooling towers often survived the applications. Reservoir sediment samples taken after treatment applications represented mortality of Corbicula in the cooling tower only and do not reflect mortality in BVPS internal water systems.

In 2004, clamicide treatments occurred on April 27, May 15, July 20, August 4, October 13, and November 19 for Unit 1 and May 4, May 18, July 27, August 10, October 19, and November 2 for Unit 2 (Table 5.22). Bioboxes spiked with live adult zebra mussels were set up to monitor the effectiveness of the treatment in Unit 2. Access precluded setting up spiked bioboxes for Unit 1, but results for Unit 2 are expected to be comparable to Unit 1. Mortality in the bioxes at 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months after treatment ranged from 81 percent to 100 percent. Mortality after 96 hours0.00111 days 0.0267 hours 1.587302e-4 weeks 3.6528e-5 months was 100 percent for all treatments except for May 4(88 percent mortality) and May 18 (95 percent mortality after 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , but then shut down).

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