SUMMARY
1.1 INTRODUCTION
This report is submitted in accordance with Section 5.4.1 of Appendix B To Facility Operating License No. NPF-73, Beaver Valley Power Station Unit 2, Environmental Protection Plan (Non-Radiological).
Beaver Valley Power Station (BVPS) is operated by FirstEnergy Nuclear Operating Company (FENOC). The Objectives of the Environmental Protection Plan (EPP) are:
- Verify that the facility is operated in an environmentally acceptable manner, as established by the Final Environmental Statement-Operating License Stage (FES-OL) and other NRC environmental impact assessments.
- Coordinate NRC requirements and maintain consistency with other Federal, State, and local requirements for environmental protection.
- Keep NRC informed of the environmental effects of facility construction and operation and of actions taken to control those effects.
To achieve the objectives of the EPP, FirstEnergy Corporation, FENOC, and BVPS, have written programs and procedures to comply with the EPP, protect the environment, and comply with governmental requirements primarily including the US Environmental Protection Agency (EPA),
and the Pennsylvania Department of Environmental Protection (PA DEP) requirements. Water quality matters identified in the Final Environmental Statements-Operating License Stage (FES-OL) are regulated under the National Pollutants Discharge Elimination System (NPDES) Permit No. PA0025615. Waste is regulated under EPA Identification No. PAR000040485. Attachment 10.1 contains a listing of permits and registrations for environmental compliance.
The BVPS programs and procedures include pre-work and pre-project environmental evaluations, operating procedures, pollution prevention and response programs procedures and plans, process improvement and corrective action programs, and human performance programs.
Technical and managerial monitoring of tasks, operations, and other activities are performed.
Any identified challenges, concerns, or questions are captured in the FENOC Problem Identification and Resolution Program with a Condition Report.
Condition Reports include investigations, cause determinations, and corrective actions.
During 2005 BVPS continued an Aquatic Monitoring Program to evaluate its potential impact on the New Cumberland Pool of the Ohio River, and to provide information on potential impacts to BVPS operation from macrofoulers such as Asian clams and Zebra mussels.

SUMMARY
AND CONCLUSIONS There were no significant environmental events during 2005. One oil release occurred that, though reported to the PA DEP, caused no significant impact to the environment, and is detailed in Section 4.0 of this report.
2005 Annual Environmental Report FENOC (BVPS)
During 2005, 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 impacts from station operation.
1.3 ANALYSIS OF SIGNIFICANT ENVIRONMENTAL CHANGE During 2005, no significant changes to were made at BVPS to cause significant negative affect on the environment.
1.4 AQUATIC MONITORING PROGRAM The 2005 Non-Radiological Monitoring Program executed 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 30th year of operational environmental monitoring for Unit I and the 19th year 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 2005 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 the Pennsylvania Department of Environmental Protection (PA DEP) to assess the ecosystem impacts of the molluscicides Betz Clamtrol CT-I, 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. Soft muck-type substrate along the shoreline found in 2005 and previous years was conducive to segmented worm (oligochaete) and midge (chironomid) proliferation.
Thirty-eight (38) macroinvertebrate taxa were identified during the 2005 monitoring program. One taxon was added to the cumulative taxa list of macroinvertebrates collected near BVPS. This was a species of unionid or native freshwater clam, Quadrula pustulosa. This species, also called the warty-back mussel, is common in the Ohio River and has been noted by the authors of this report during other field studies at BVPS.
No state or federal threatened or endangered macroinvertebrate species were collected during 2005. In May, chironomids were the most frequently collected, while oligochaetes were the most frequently collected groups in September. There were no major differences in the community structure between control and non-control stations that could be attributed to operation of BVPS. The overall community structure has changed little since pre-operational years, and program results did not indicate that BVPS operations were affecting the benthic community of the Ohio River.
2005 Annual Environmental Report 2
of the Ohio River.
The fish community of the Ohio River near the BVPS was sampled in May, July, September and November of 2005 with night 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.
During the survey, forage species were collected or observed in the highest numbers, principally gizzard shad and emerald shiner. This is indicative of a healthy fish community, since game species rely on the availability of abundant forage for survival. White bass, golden redhorse sucker, shorthead redhorse sucker, black buffalo, and smallmouth bass were also commonly collected in 2005.
The catch per unit effort (number of fish per minute of effort, or CPUE) for electrofishing in 2005 was 1.73 fish/min, which was slightly higher than in previous years (2003 and 2004) when the CPUE was stable at 1.28 fish/min. The difference in year-to-year CPUE was primarily due to a larger number of gizzard shad collected in the fall and winter surveys of 2005.
Little difference in the species composition of the catch was observed between the control (Station I) 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. Results from the 2005 fish surveys indicated that a normal community structure for the Ohio River exists near BVPS based on species composition and relative abundance. In 2005, 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 I and 2 cooling towers and the four samples collected at the intake during 2005 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 2005, 2004 and 2003. The density of veligers in 2005 and 2004 were comparable but was less than in 2003. 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. Whether the population of zebra mussels in this reach of the Ohio River isplateauing and onlyyearlyfluctuations are present cannot be determined.
In any case, the densities of mussels that presently exist are more than sufficient to impact the BVPS, if continuedprudent monitoring and control activities are not conducted 2.0 ENVIRONMENTAL PROTECTION PLAN NON-COMPLIANCES There were no Environmental Protection Plan non-compliances identified in 2005.
2005 Annual Environmental Report 3
3.0 CHANGES INVOLVING UNREVIEWED ENVIRONMENTAL QUESTIONS No Unreviewed Environmental Questions were identified in 2005. Therefore, there were no changes involving an Unreviewed Environmental Question.
4.0 NONROUTINE ENVIRONMENTAL REPORTS During 2005, BVPS made one non-routine environmental report and required associated follow-up report to the PA DEP.
NOTE:
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.
4.1 Hydrazine Detected at Internal Monitoring Point (IMP) 103:
On December 20, 2005, we analytically determined hydrazine to be present at IMP 103 (Clarifier Settling Basin) in a concentration of 134 ug/l. Because hydrazine was not administratively identified as a pollutant with controls and monitoring requirements at IMP 103 in our NPDES Permit (No. PA0025615), by telephone we immediately notified the PA DEP in accordance with Part A.(4)a and A.(4)d of the permit. In accordance with the permit (Part A Reporting Requirements) we submitted the five-day follow-up written notification on December 23, 2005 under our Letter No. L-05-205. In accordance with our site reporting guidance BVBP-SITE-0016 - Required Reports, we submitted a copy of that letter to the USNRC Document Control Desk. Finally, in accordance with the permit requirements, we summarized the event, investigation, and corrective actions taken, with the December 2005 Discharge Monitoring Reports (DMR) submitted to the PA DEP, US EPA, and the USNRC.
The incident was investigated and corrective action plan developed in the FENOC Problem Identification and Resolution program (PI&R) under CR-05-08062. There was no detection of harm to the environment.
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 2005 Annual Environmental Report 4
requirements.
However, in the interest of providing an uninterrupted database, BVPS has continued the Aquatic Monitoring Program.
The objectives of the 2005 environmental program were:
- To monitor for any possible environmental impact of BVPS operation on the benthic macroinvertebrate and fish communities in the Ohio River;
- 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 (Dreissena spp.) at BVPS.
5.1 Site Description BVPS is located on an approximately 501-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 I mile (1.6 km) 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 3.3 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.
The study 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.
BVPS Units 1 and 2 have a thermal rating of 2,660 megawatts (MW). Units 1 & 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 I began in 1976 and Unit 2 began operation in 1987.
5.2 Study Area The environmental study area, established to assess potential impacts, consists of four sampling 2005 Annual Environmental Report 5
stations each having a north and south shore (Figure 5.1). Station I 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 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 mile downstream of the BVPS discharge structure. Station 2B is the principal non-control 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.
5.3 Methods Shaw Environmental and Infrastructure, Inc. (Shaw) was contracted to perform the 2005 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 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 EPA 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 2005. For each 2005 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.
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/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.
5.3.2 Fish Monitoring Fish sampling was conducted in 2005 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.
2005 Annual Environmental Report 6
Fish population surveys have been conducted in the Ohio River near BVPS annually from 1970 through 2005. These surveys have resulted in the collection of 73 fish species and five different hybrids.
Adult fish surveys were scheduled and performed in May, July, September, and November 2005.
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 electrofishing catches (e.g., young-of-the-year fish and small cyprinids).
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 a 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 "lon" 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 2005 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 I 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 I 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 Corbicula Density Determinations for Cooling Tower Reservoirs The Corbicula Monitoring Program at BVPS includes sampling the circulating river water and 2005 Annual Envirorlnental Report 7
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 2005.
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.
The Cooling Tower Reservoir Sampling was historically conducted once per month, annually.
Beginning in December 1997, it was decided to forego sampling in December and January of each year, since buildup of Corbicula does not occur in these cold water months. Monthly sampling has been maintained throughout the balance of the year. In 2005 sampling began in April.
In 2005, once each month (April 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 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 through 2005) 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 2005, so no samples were collected.
5.3.4 Corbicula Juvenile Monitoring The Corbicula juvenile study was designed to collect data on Corbicula spawning activities and 2005 Annual Environmental Report 8
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 Corbicula that entered the BVPS.
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 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 18, 1998 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).
In 2002, because of site protection considerations, the sampling with petite ponar was 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 offshore of the intake building.
These grab samples are processed in the same manner as when they were collected from within the Intake Structure Building.
5.3.5 Zebra Mussel Monitoring The Zebra Mussel Monitoring Program included the Ohio River and the circulating river water system of the BVPS. This section describes this Monitoring Program and the results obtained during Ohio River and BVPS surveys conducted through 2005.
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 December and January of each year, since buildup of zebra mussels, does not occur in these cold water months.
Monthly sampling has been maintained throughout the balance of the year. In 2005 the award of 2005 Annual Environmental Report 9
contract delayed the initiation of sampling until April.
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 tower of Unit 1 and Unit 2 in October 1998.
In 2004 to present, these additional locations were sampled from March through October. In 2005 sampling began in April.
At the Intake Structure and Barge Slip the following surveillance techniques were used:
- Wall scraper sample collections on a monthly basis (April 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 (April through November); and
- 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 (April through November); and
- 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.
5A.1 Benthic Macroinvertebrate Monitoring Program Benthic surveys were scheduled and performed in May and September 2005. Benthic samples 2005 Annual Environmental Report 10 FENOC (BVPS)
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, 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 soft muck substrates composed of sand, silt, and detritus. An exception was along the north shoreline of Phillis Island at Station 2A where hard pan clay 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 scouring by river currents.
Thirty-eight (38) macroinvertebrate taxa were identified during the 2005 monitoring program (Tables 5.2 and 5.3). A mean density of 767 macroinvertebrates/m 2 was collected in May and 5,627/M2 in September (Table 5.4). As in previous years, the macroinvertebrate assemblage during 2005 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).
Eighteen (18) taxa were present in the May samples, and thirty-two (32) taxa in the September samples (Table 5.3). Twelve (12) of the 38 taxa were present in both May and September.
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 1997-2005 sampling programs (see Sections 5.4.5 Zebra Mussel Monitoring Program). Both species were collected in benthic macroinvertebrate samples in 2005.
In 2005, one taxon was added to the cumulative taxa list of macroinvertebrates collected near BVPS (Table 5.2). This was a species of unionid or native freshwater clam, Quadrula pustulosa.
This species, also called the warty-back mussel, is common in the Ohio River and it has been noted by the authors of this report during other field studies at BVPS.
No state or Federal threatened or endangered macroinvertebrate species were collected during 2005.
In May 2005 samples, chironomids accounted for the highest mean density of macroinvertebrates and oligochaetes had the second highest (401/m 2 or 52.3 percent of the total density and 280/M2 or 36.5 percent, respectively) (Table 5.4).
Mollusks and organisms other then oligochaetes, chironomids and mollusks had lower mean densities (43m2 or 5.6 percent of the total each).
In September 2005 samples, oligochaetes accounted for the highest mean density of macroinvertebrates and chironomids had the second highest (3,218/M2 or 57.2 percent of the total 2005 Annual Environmental Report 11 FENOC (BVPS)
density and 1,455/m2 or 25.8 percent, respectively) (Table 5.4). Mollusks had the third highest mean density in September 2005 (839/m or 15.0 percent) while the "others" category had the fourth highest mean density (115/rm2 or 2.0 percent).
In May, the highest density of macroinvertebrates (1,806 organisms/m2) occurred at Station 2B1.
In September, the highest density of macroinvertebrates also occurred at Station 2B1 (9,546/M2).
The both May and September the lowest mean density of organisms occurred at Station 3 (172/M2 and 3,569/m2, respectively).
For a comparison of the control to non-control stations, Station I 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) was designated as the non-control station, since it is the 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 over two times higher (1,146/M2) than that of the control station (516/m2) in May (Table 5.5).
The density of chironomids was about 16 times higher at the non-control station (702/M2) than at the non-control station (43/m2). The density of oligochaetes was comparable between control and non-control. Mollusks were present at greater densities at the control stations (86/M2) than at the non-control station (43/m2). Other taxa were only present at the non-control stations. 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 was somewhat higher at the non-control than at the control station. The density of macroinvertebrates in both the control and non-control stations was higher in September than in May. Oligochaetes occurred at much higher densities at the non-control than the control stations. Chironomids were present at higher densities at the non-control station than the control station. The density of mollusks was also higher in the non-control station than in the control. The densities of chironomids, and others were higher in the control station than the non-control. 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 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.
2005 Annual Environmental Report 12 FENOC (BVPS)
The Shannon-Weiner diversity indices in May 2005 collections ranged from 0.49 at Station 2B1 to 0.71 at Station 2B3 (Table 5.6). In May evenness ranged from 0.68 at Station 2B2 to 1.00 at Station 3. The high evenness at Station 3 was due to only single organisms in each of four taxa being collected at this station. Richness was greatest at Station 1 (2.41) and lowest at Station 2B1 (1.34). The diversity of the macroinvertebrate community in September was generally comparable to that in May. Diversity ranged from 0.61 at Station 2B2 to 0.87 at Station 1.
Evenness was also comparable in September to May and ranged from 0.56 at Station 2B3 to 0.75 at Station 2B1. Richness was greatest at Station 1 (3.61) and lowest at Station 2B2 (2.33).
In May, the number of taxa, diversity, evenness and richness indices were comparable in the control station (Station 1) and in the non-control stations (2B1, 2B2, 2B3) (Table 5.6).
In September the same pattern held true. 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 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 2005 fell within the range of densities of macroinvertebrates 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-operational years, and the available evidence does not indicate that BVPS operations have affected the benthic community of the Ohio River).
5.4.2 Fish Sampling Program In 2005, 482 fishes representing 25 taxa were collected (i.e., handled) during BVPS surveys by electrofishing and seining (Table 5.8). All taxa collected in 2005 were previously encountered at BVPS. The most common species in the 2005 BVPS surveys, collected by electrofishing and seining combined, were gizzard shad (34.2% of the total catch), followed by emerald shiner (11.6
%), white bass (9.5%/6), golden redhorse sucker (7.3%), shorthead redhorse sucker (7.1%), and black buffalo (6.4%). The remaining 19 species combined accounted for 23.9% of the total handled catch. The most frequently observed (handled and not handled combined) fish in 2005 were gizzard shad (Tables 5.9, 5.10, and 5.15). Game fishes collected during 2005 included channel catfish, flathead catfish, white bass, bluegill, smallmouth bass, sauger, walleye, and spotted bass. Game fishes represented 21.8 % of the total handled catch, 9.5% of which were white bass.
A total of 281 fish, representing 22 taxa, was collected by electrofishing in 2005 (Table 5.9).
Gizzard shad and white bass accounted for the largest portion of the 2005 electrofishing catch (22.8% and 15.7%, respectively) followed by golden redhorse sucker (12.5%), shorthead redhorse sucker (12.1%), black buffalo (7.8%) and sauger (6.8%). No other species collected 2005 Annual Environmental Report 13 FENOC (BVPS)
A total of 201 fish representing 11 taxa was collected by seining in 2005 (Table 5. 10). The most abundant taxa collected were gizzard shad (50.3% of the total catch) followed by emerald shiner (27.9%) and smallmouth bass (6.0%). Other game species collected by seining were white bass and spotted bass. No other species collected contributed to greater than five percent of the total catch.
A total of 56 fish representing 16 species was captured during the May 2005 sample event (Table 5.1 1). A total of 54 fish representing 15 species was collected during electrofishing and two fish from one species was collected during seine netting. Golden redhorse sucker (35.2% of the total catch), gizzard shad (14.8%) and black buffalo (9.3%) were the most common species boated during the electrofishing effort. Sauger and channel catfish (5.6% each) was the most abundant game species collected in May. Two mimic shiners were the only fish collected during the seining effort.
A total of 161 fish representing 15 species were captured during the July 2005 sample event (Table 5.12). A total of 31 fish representing 10 species were collected during electrofishing and 130 fish representing nine species were collected during seine netting. Gizzard shad (45.1% of the total catch), golden redhorse sucker (16.1%), and shorthead redhorse sucker (12.9%) were the most common species boated during the electrofishing effort. White bass was the most abundant game species representing 6.5% of the total catch followed by channel catfish, flathead catfish, and smallmouth bass, each representing 3.2% of the total catch. Well over 1,000 young of the year gizzard shad that were too small to net were stunned and not collected during the July electrofishing study (Table 5.15). Young of the year gizzard shad (70% of the total catch) was the most frequently collected species during the seining efforts followed by smallmouth bass (9.2%), and black buffalo (6.9%).
During the September sample event, 110 fish representing 17 taxa were collected (Table 5.13). A total of 76 fish representing 13 species was collected during electrofishing and 34 fish representing five species were collected during seine netting. White bass (32.9% of the total catch) and gizzard shad (31.6%) were the most abundant species collected electrofishing followed by shorthead redhorse sucker (7.9%), quillback, and black buffalo (5.3% each).
Flathead catfish (2.6%), and channel catfish, walleye, and smallmouth bass (1.3% each) comprised the other game species collected during electrofishing efforts in September. Fish observed and not collected in the September electrofishing study are presented in Table 5.15.
Emerald shiner (61.8%) and gizzard shad (29.41%) were the most commonly collected species collected in seining in September.
During the November sample event, 155 fish representing 20 taxa were captured (Table 5.14). A total of 120 fish representing 17 species was collected during electrofishing and 35 fish representing three species were collected during seine netting. Shorthead redhorse sucker (16.8%
of the total catch) was the most abundant species collected by electrofishing followed by gizzard shad (15.0%) white bass (14.2%), sauger (11.7%), and black buffalo (10.0%). Smallmouth bass (4.2%), and walleye, spotted bass, and bluegill (each 1.7%) were the other game species collected by electrofishing.
Fish observed and not collected in the November electrofishing study are presented in Table 5.15. Emerald shiner (82.9% of the total catch), spotfin shiner (11.4%) and 2005 Annual Environmental Report 14 FENOC (BVPS)
by electrofishing.
Fish observed and not collected in the November electrofishing study are presented in Table 5.15. Emerald shiner (82.9% of the total catch), spotfin shiner (11.4%) and northern hogsucker (5.7%) were the only species collected during the seining efforts in November.
Electrofishing catch rates are presented in Tables 5.16, 5.17, and 5.18 for fish that were boated and handled during the 2003 through 2005 surveys by season (FENOC 2003 and 2004). In 2005, the annual catch rate was 1.73 fish per minute. The greatest catch rate in 2005 occurred in November (winter) (2.93 fish/ electrofishing minute). A large number of shorthead redhorse, and gizzard shad contributed to this total. The lowest catch rate occurred in July (summer) with a rate of 0.78 fish/ electrofishing minute. The annual catch rates were consistent over the three years ranging from a high of 1.73 fish per minute in 2005 to 1.27 in 2003 and 2004. In 2003 and 2004 the lowest catch rate was in the fall whereas in 2005 the lowest catch rate was during the summer survey 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 2005 (Table 5.10) indicated no major differences in species composition between control and non-control stations. Gizzard shad and emerald shiner were 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.
In 2005, species composition remained comparable among stations. Common taxa collected in the 2005 surveys by all methods included gizzard shad, emerald shiner, redhorse sucker species, black buffalo, sauger, quillback, and walleye. Little difference in the species composition of the catch was observed between the control (1) 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.
The results of the 2005 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. 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 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, which could be the reason for the large numbers of these species observed in 2005. 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.
2005 Annual Environmental Report 15 FENOC (BVPS)
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 decrease the collection efficiency of this gear.
5A.3 Corbicula Monitoring Program In 2005, 48 Corbicula (29.2 percent alive) were collected from the Unit 1 cooling tower basin during monthly reservoir sampling. No Corbicula were collected in the scraping samples. 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 Corbicula were collected in November (21 individuals). The mean density of Corbicula in Unit 1 in 2005 was 260/m2. Corbicula were collected in lower numbers in the other months sampled and not collected in June, July or August.
In 2005, 99 Corbicula (27.3 percent alive) were collected from the Unit 2 cooling tower reservoir during monthly sampling. The largest live Corbicula collected was within the 4.74-6.29 mm length size range (Table 5.20 and Figure 5.6). Individuals were collected from June through September. The mean density of Corbicula in Unit 2 in 2005 was 532/m2. The greatest number of Corbicula (42 individuals) were collected in July.
In 2005, BVPS continued its Corbicula control program (Year 15), which included the use of a quaternary amine-based non-oxidizing molluscicide (GEBetz Powerline 3627) to prevent the proliferation of Corbicula within BVPS. The treatment is authorized in the BVPS NPDES Permit No. PA0025615.
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 treatments targeted the internal water systems; therefore, the biocide concentrations in the cooling towers were reduced during macrofouler treatments. Consequently, adult and juvenile Corbicula in the cooling towers often survived. Reservoir sediment samples taken after Powerline applications represent mortality of Corbicula in the cooling tower only and do not reflect mortality in BVPS internal water systems.
Since 1999, BVPS has conducted three macrofouler treatments each year. They are scheduled to start in mid-April, July, and September. One subsystem per unit is targeted at a time-as follows:
Unit 1 "A" Train, Unit 2 "A" Train, Unit I "B" Train, and Unit 2 "B" Train (though not necessarily in that order. That schedule was executed again in 2005. There were no internal biobox monitoring data, however, due to a unique configuration of the Unit 2 Service Water system for replacement of a heat exchanger. The configuration precluded the installation of a side-stream monitoring device, and no viable option exists at Unit 1.
2005 Annual Environmental Report 16 FENOC (BVPS)
The monthly reservoir sediment samples collected in Units 1 and 2 Cooling Towers during 2005 demonstrated that Corbicula were entering and colonizing the reservoirs. Overall, densities in Unit 1 were somewhat less than those in 2004 and in Unit 2 densities were slightly greater than in 2004.
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.
5A.4 Corbicula Juvenile 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 in 2005. Corbicula were collected during July, September and November. Only one individual was collected during July and November, while 15 Corbicula were collected in September. They were generally small, which indicated that they were spawned in 2005. The number of individuals collected was consistent with the mean of the prior three years (25 in 2002, eight in 2003, and two in 2004).
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. 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 2005, compared to levels in the 1980's, likely reflects a natural decrease in the density of Corbicula in the Ohio River near BVPS.
5.4.5 Zebra Mussel Monitoring Program Zebra mussels (Dreissena polymorpha) 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.
Zebra mussels were detected in both pump samples (Figures 5.9 and 5.10) and substrate samples (Figure 5.11 and 5.12) in 2005. Zebra mussel veliger pump samples were collected from April through October 2005 (Figures 5.9 and 5.10). Veligers were collected at all of the six sites that were sampled in 2005. Densities of veligers generally peaked in late June, although they were present in relatively high densities at some sample sites in August and September. The greatest density of veligers was present in the sample collected from the splash pool in late-June (970/M3). Veligers were first present in samples collected in April. Veligers were present in all 2005 Annual Environmental Report 17 FENOC (BVPS)
samples collected in late-June and September. Overall, veliger densities were consistent with 2004 but lower than in 2003. In 2003, the greatest density collected was 52,560/M3. Whether the lower densities are due to an overall decrease in numbers of veligers in the Ohio River in 2004 and 2005 or due to the limited number of samples and the propensity of veligers to be non-uniformly distributed in the water is uncertain.
In 2005, settled zebra mussels were collected in scrape samples at all of the sites sampled except the Emergency Outfall Facility (Figures 5.11 and 5.12). The highest density of mussels was present in the sample collected at the intake (6 mussels/m2). The mussels collected at each of the sites included individuals that were of reproducing age. The density of collected adult zebra mussels was consistent with past years.
Overall, both the number of observations and densities of settled mussels were similar in 2005, 2004 and 2003. The density of veligers in 2005 and 2004 were comparable but was less than in 2003. 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. Whether the population of zebra mussels in this reach of the Ohio River is plateauing and 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 activities are not conduced.
6.0 ZEBRA MUSSEL AND CORBICULA CONTROL ACTIVITIES In 2005, BVPS continued its Corbicula and Zebra mussel control program (Year 15), which included the use of a quaternary amine-based non-oxidizing molluscicide (GEBetz Powerline 3627) to prevent the proliferation of Corbicula and Zebra mussels within BVPS. The treatment is authorized in the BVPS NPDES Permit No. PA0025615.
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 treatments targeted the internal water systems; therefore, the biocide concentrations in the cooling towers were reduced during macrofouler treatments. Consequently, adult and juvenile Corbicula in the cooling towers often survived. Reservoir sediment samples taken after Powerline applications represent mortality of Corbicula and Zebra mussels in the cooling tower only and do not reflect mortality in BVPS internal water systems.
Since 1999, BVPS has conducted three macrofouler treatments each year. They are scheduled to start in mid-April, July, and September. One subsystem per unit is targeted at a time-as follows:
Unit I "A" Train, Unit 2 "A" Train, Unit I "B" Train, and Unit 2 "B" Train (though not necessarily in that order. That schedule was executed again in 2005. There were no internal biobox monitoring data, however, due to a unique configuration of the Unit 2 Service Water system for replacement of a heat exchanger.
