HAZARDS IDENTIFICATION Emergency Overview: Appearance and Odor: Reddish brown liquid, phenolic-amine odor.Warning Statements: DANGER. Keep out of reach of children. Corrosive. Causes irreversible eye damage. Harmful if swallowed. May be fatal if absorbed through the skin. Avoid breathing vapors or spray mist. Do not get in eyes, on skin or on clothing.Potential Adverse Health Effects: MSDS: Nufann Weedar 64 Broadleaf Herbicide Page 2 of 7 f Likely Routes of Exposure: Inhalation, eye and skin contact.Eye Contact: Causes corneal opacity, irreversible eye damage. Vapors and mist can cause irritation. Skin Contact: May cause slight transient irritation. Overexposure by skin absorption may cause nausea, vomiting, abdominal pain, decreased blood pressure, muscle weakness, muscle spasms.Inhalation: Harmful if inhaled. May cause upper respiratory tract irritation and symptoms similar to those from ingestion. Ingestion: Harmful if swallowed. May cause nausea, vomiting, abdominal pain, decreased blood pressure, muscle weakness, muscle spasms.Medical Conditions Possibly Aggravated By Exposure: Inhalation of product may aggravate existing chronic respiratory problems such as asthma, emphysema or bronchitis. Skin contact may aggravate existing skin disease.Subchronic (Target Organ) Effects: (An adverse effect with symptoms that develop slowly over a long period of time): Repeated overexposure may cause effects to liver, kidneys, blood chemistry, and gross motor function. Rare cases of peripheral nerve damage have been reported, but extensive animal studies have failed to substantiate these observations, even at high doses for prolonged periods.Chronic Effects/Carcinogenicity: Prolonged overexposure can cause liver, kidney and muscle damage. The International Agency for Research on Cancer (IARC) lists exposure to chlorophenoxy herbicides as a class 2B carcinogen, the category for limited evidence for carcinogenicity in humans. However, more current 2,4-D lifetime feeding studies in rats and mice did not show carcinogenic potential. The USEPA has given a class D classification (not classifiable as to human carcinogenicity). Reproductive Toxicity: No impairment of reproductive function attributable to 2,4-D has been noted in laboratory animal studies.Developmental Toxicity: Studies in laboratory animals with 2,4-D have shown decreased fetal body weights and delayed development in the offspring at doses toxic to mother animals.Genotoxicity: There have been some positive and some negative studies, but the weight of evidence is that 2,4-D is not mutagenic.

4. FIRST AID MEASURES If swallowed:

If patient is conscious and alert, give 2 to 3 glasses of water or milk to drink. If available, give one tablespoon of Syrup of Ipecac to induce vomiting. Alternatively, induce vomiting by touching back of throat with finger. Do not make an unconscious person vomit. Get medical attention. If on skin: Wash skin with plenty of soap and water. Remove contaminated clothing. Get medical attention. If in eyes: Flush with water for at least 15 minutes. Get medical attention, PREFERABLY AN OPHTHALMOLOGIST. If inhaled: Move to an uncontaminated area. Get medical attention. Note to Physician: This product contains a phenoxy herbicidal chemical. There is no specific antidote. All treatments should be based on observed signs and symptoms of distress in the patient. Overexposure to materials other than this product may have occurred.Myotonic effects may include muscle fibrillations, myotonia, and muscular weakness. Ingestion of massive doses may result in persistent fall of blood pressure. Myoglobin and hemoglobin may be found in urine. Elevations in lactate dehydrogenase (LDH), SGOT, SGPT and aldolase indicate the extent of muscle damage. It has been suggested that overexposure in humans may affect both the central and peripheral nervous systems. The acute effects on the central nervous system resemble those produced by alcohol or sedative drugs. In isolated cases, peripheral neuropathy and reduced nerve conduction velocities have been reported although these observations may be related to other factors. Gas-liquid chromatography for detecting and measuring chlorophenoxy compounds in blood and urine may be useful in confirming and assessing the magnitude of chlorophenoxy absorption.

HAZARDOUS IDENTIFICATIONS: EYE: May cause severe irritation with corneal injury, which may result in permanent impairment of vision, even blindness. Vapors of amines may cause swelling of the cornea resulting in visual disturbances such as blurred, smoky or halo vision. When tested on animals, dilutions of this material were less irritating to eyes than the undiluted product.I SKIN: Prolonged or repeated exposure may cause skin irritation, even a bum. When tested on animals, dilutions of this material were less irritating to skin than the undiluted product. Prolonged or frequently repeated skin contact may cause allergic skin reactions in some individuals. With the dilute mix, no allergic skin reaction is expected. A single prolonged exposure is not likely to result in the material being absorbed through the skin in harmful amounts. The LD 5 0 for skin absorption in rabbits is >5000 mg/kg.INGESTION: Single dose oral toxicity is low. The oral LD 5 0 was 2574 mg/kg for male rats and 1847 mg/kg for female rats. Small amounts swallowed incidental to normal handling operations are not likely to cause injury; however, swallowing larger amounts may cause injury. Ingestion may cause gastrointestinal irritation or ulceration. INHALATION: A single brief (minutes) inhalation exposure is not likely to cause adverse effects.SYSTEMIC (OTHER TARGET ORGAN) EFFECTS: Excessive exposure may cause liver or kidney effects.CANCER INFORMATION: Triclopyr did not cause cancer in laboratory animal studies. This material contains ethanol.Epidemiology studies provide evidence that drinking of alcoholic beverages (containing ethanol) is associated with cancer, and IARC has classified alcoholic beverages as carcinogenic to humans.TERATOLOGY (BIRTH DEFECTS): For triclopyr, birth defects are unlikely. Even exposures having an adverse effect on the mother should have no effect on the fetus.Ethanol has been shown to cause birth defects and toxicity to the fetus in laboratory animal tests. It has also been shown to cause human fetotoxicity and/or birth defects when ingested during pregnancy. EMERGENCY OVERVIEW Hazardous Chemical. Light purple-pink liquid, ammonia-like odor.

It is practically non-irritating to the eyes and non-irritating to the skin. Large doses of bifenthrin ingested by laboratory animals produced signs of toxicity including convulsions, tremors and bloody nasal discharge. Bifenthrin does not cause acute delayed neurotoxicity. Experience to date indicates that contact with bifenthrin may occasionally produce skin sensations such as rashes, numbing, burning or tingling. These sensations are reversible and usually subside within 12 hours.CHRONIC EFFECTS FROM OVEREXPOSURE: No data available for the formulation. In studies with laboratory animals, bifenthrin did not cause reproductive toxicity or teratogenicity. Tremors were associated with repeated exposure of laboratory animals to bifenthrin. In lifetime feeding studies conducted with rodents, a slight increase in the incidence of urinary bladder tumors at the highest dose in male mice was considered to be an equivocal response, not evidence of a clear compound-related effect. The overall absence of genotoxicity has been demonstrated in mutagenicity tests with bifenthrin. CARCINOGENICITY: IARC: Not listed NTP: Not listed OSHA: Not listed OTHER: Not Listed (ACGIH)SECTION 12 -ECOLOGICAL INFORMATION Unless otherwise indicated, the data presented below are for the active ingredient. ENVIRONMENTAL DATA: In soil, bifenthrin is stable over a wide pH range and degrades at a slow rate which is governed by soil characteristics. Bifenthrin will also persist in aquatic sediments. Bifenthrin has a high Log Pow (>6.0), a high affinity for organic matter, and is not mobile in soil. Therefore, there is little potential for movement into ground water. There is the potential for bifenthrin to bioconcentrate (BCF = 11, 750).ECOTOXICOLOGICAL INFORMATION: Bifenthrin is highly toxic to fish and aquatic arthropods and LC50 values range from 0.0038 to 17.8 pg/L. In general, the aquatic arthropods are the most sensitive species. Care should be taken to avoid contamination of the aquatic environment. Bifenthrin had no effect on mollusks at its limit of water solubility. Bifenthrin is only slightly toxic to both waterfowl and upland game birds (LD50 values range from 1,800 mg/kg to >2,150 mg/kg).SECTION 13- DISPOSAL CONSIDERATIONS DISPOSAL METHOD: Open dumping or burning of this material or its packaging is prohibited. If spilled material cannot be disposed of by use according to label instructions, an acceptable method of disposal is to incinerate in accordance with local, state and national environmental laws, rules, standards and regulations. However, because acceptable methods of disposal may vary by location and regulatory requirements may change, the appropriate agencies should be contacted prior to disposal.EMPTY CONTAINER: Non-returnable containers which held this material should be cleaned, prior to disposal, by triple rinsing. Containers which held this material may be cleaned by being triple-rinsed, and recycled, with the rinsate being incinerated. Do not cut or weld metal containers. Vapors that form may create an explosion hazard.14 -TRANSPORT INFORMATION U.S. DEPARTMENT OF TRANSPORTATION (DOT)REPORTABLE QUANTITY (RQ): None U.S. SURFACE FREIGHT CLASS: Insecticides, NOI, other than Poison.

An important part of keeping electricity reliable is maintaining transmission and distribution power line rights of way to prevent service interruptions from trees and other tall vegetation. A loss of service can be inconvenient, costly to our customers, and may disrupt vital services, such as electricity to hospitals, fire departments and individuals on life-support systems.For this reason, Progress Energy uses a variety of methods to manage unwanted vegetation on rights of way. We evaluate methods for safety, environmental impact and costs. Because of the variety of terrain, differences in soils and land use and vegetation type, Progress Energy uses an Integrated Vegetation Management (IVM) approach, which includes both mechanical and chemical control methods.Progress Energy right-of-way maintenance is performed by contractors using a variety of methods. Mechanical methods include pruning, felling, mowing and hand clearing. Chemical controls involve the use of herbicides, which are used to control woody vegetation that reseeds or resprouts after mowing.Without herbicide applications, these sprouts grow quickly and require repetitive mowing. Over time, the use of herbicides results in the growth of favorable low-growing, nonwoody plants, such as grasses and other native plants. These new plant communities do not interfere with power lines and the reliable flow of electricity to our customers. In addition, they provide a natural habitat that benefits many kinds of wildlife. As a result, there is a reduced need for future mowing and herbicide applications. Progress Energy's IVM approach balances concerns for human safety, animals and pets, agricultural crops and overall environmental issues. The herbicides used at Progress Energy have been approved for use on power line rights of way by the U.S. Environmental Protection Agency (EPA). The EPA requires rigorous toxicological, environmental and chemical testing before the herbicides are registered for use. Also, the herbicides Progress Energy uses have the same chemical ingredients as those our customers can purchase in stores (such as RoundupTM) for controlling weeds in gardens, yards and for agricultural practices. Most importantly, our applications are performed under the supervision of a licensed applicator. Progress Energy evaluates its right-of-way management program throughout our service area to be certain that all segments of power lines are accessible for maintenance of facilities and..v* ., ; ": '."

Natural vegetation serves as a source of food and shelter for many animals, such as song birds, quail, wild turkey, deer and rabbits. For these reasons, the herbicides selected are designed specifically to control vegetation and to minimize the risk to wildlife.Mindful of our need to be good environmental stewards, Progress Energy works with federal, state and local governmental agencies and environmental organizations to identify and protect natural ecosystems and rare plants located within our rights of way, which we protect by selectively managing these sites. Progress Energy makes every effort to conserve compatible native plants within our rights of way that are valuable to wildlife and to control invasive exotic plants that threaten sensitive ecosystems. We have found that many of our customers are pleased with this herbicide program. However, for organic farmers and others with concerns, we can provide other options.

Through the use of different, integrated methods, the optimum results (reliability, etc.) occur reducing the need to employ reliability-based trimming/removal and danger tree cutting.Progress Energy Transmission utilizes easements, permits and/or company owned lands for the right of way on which the transmission lines are constructed. The routine inspection and maintenance of the right of ways (ROW) are extremely important for the safety of the public and the personnel that are responsible for the operation/maintenance of the transmission lines. Maintaining right of ways in accordance with established procedures results in a high level of transmission line reliability. 2.0 Program Policies, Procedures, Components and Specifications (FAC-003 R1)2.1 Program Objectives Ensure the reliability of the transmission system by minimizing vegetation related interruptions, while maintaining compliance with regulatory, environmental and safety requirements/standards. 2.2 Philosophy Our philosophy is based upon employing the proper, most economical vegetation management techniques to ensure the effectiveness of our program in a wide variety of environments. This is achieved through communication, continuous learning and assessing best management practices throughout the industry.IMNT-TRMX-00176 Rev. 2 (02/07) 1 Page 1 of 12 1 AUTHORIZED COPY 2.3 Program Scope The visual inspection and appropriate maintenance of transmission line right of ways comprise the Transmission Vegetation Management Program.Inspections (periodic aerial and as needed ground patrols) are performed to monitor vegetation growth, right of way contractor effectiveness and encroachments within the right of way. Maintenance activities may include any of the following: re-clearing vegetation (mechanical clearing, hand cutting and herbicide application), tree trimming/removal, danger tree cutting and encroachment licensing/removal. All transmission lines at voltages of 200 KV and higher will maintain 100%compliance with the MNT-TRMX-00176 specifications and cycle frequencies. All transmission lines at voltages less than 200KV will utilize MNT- TRMX-001 76 as a standard and apply appropriate IVM methods as required to ensure the reliability of the line.This procedure shall be followed in accordance with Section 3 "Preventive Maintenance Program" requirements in the Transmission Maintenance Procedures Policy (MNT-TRMX-00000). 2.4 Program Work Components All work performed shall be in accordance with ANSI, OSHA and other applicable safety requirements, laws and Progress Energy guidelines. The following describes the various components that are utilized in the Progress Energy Transmission's Integrated Vegetation Management Program.Right of way re-clearing (using mechanical equipment -e.g., rotary mowers, Kershaw, Hydro-Ax, etc.) -All of the wooded sections of the right-of-way are to be re-cleared with mechanical equipment, where possible, to the full width as noted in a detail description. All undergrowth is to be cut within six (6) inches of the ground. All vines on poles and brush around poles in fields are to be cut and removed out of cropped areas. Cut all leaning trees that have been pulled into the right-of-way by storms. All brush cut from stream banks or drainage ditches must be removed from streams and ditches so as not to impede the flow of water. When run ways are cut through existing canals, the canal must be restored to original condition allowing drainage to continue as it did before our operation. The vista screens and trimmed trees are not to be cut without specific instructions from Company representative. Right of way re-clearing (hand-cutting) -All of the wooded sections of the right-of way that cannot be re-cleared with mechanical equipment are to be hand cut to the full width as noted in a detail description. All undergrowth is to be cut within six (6)inches of the ground or current water level. All vines on poles and brush around poles in fields are to be cut and removed out of cropped areas. Cut all leaning trees that have been pulled into the right-of-way by storms. All brush cut from stream MNT-TRMX-00176 Rev. 2 (02/07) Page 2 of 12 AUTHORIZED COPY banks or drainage ditches must be removed from streams and ditches so as not to impede the flow of water. The vista screens and trimmed trees are not to be cut without specific instructions from a Progress Energy representative. Right of way re-clearing (herbicides) -Where appropriate, the primary method of vegetation control on transmission right of ways may be established as, or converted to, the use of herbicides. Herbicides may also be applied on a case by case basis on areas of line right of ways that cannot be effectively, or efficiently, mowed or hand-cut. The application of herbicides on Transmission ROW shall be in accordance with procedure EVC-EDGC-00001 (Herbicide Usage on Rights-of-Way Energy Delivery Carolinas only) and all applicable TVM specifications. Tree removal/trimming -All trees requiring removal/trimming should be removed or trimmed so as to obtain sufficient clearance to prevent a hazard to operations for the removal/trimming cycle.Off right of way tree cutting -Off right of way trees are those trees located outside the defined right of way width. These trees, due to there height if they were to fall could make contact with the conductor or fall to within five feet of the outermost conductor, grow into the conductor or due to conductor blowout could make contact with the conductor. All trees cut are to be cut according to MNT-TRMX-00193 (TVM: Off Right of Way Tree Cutting Guidelines). Danger tree cutting -Danger trees are those trees located inside or outside the designated right of way that are in decline/diseased, have structural defects, leaning towards the right of way or are dead. These trees, due to there height if they were to fall could make contact with the conductor or fall to within five feet of the outermost conductor. These trees should be inspected and assessed thoroughly for structural integrity before climbing is performed. When the safety of the crew is at risk if the tree is climbed, alternate mechanical or other methods shall be utilized to perform the removal safely.2.4.1 Program Component Frequency Targets The actual frequency for specific facilities may vary significantly from the target frequency based on the integrated program components that are being employed and on site/facility specific factors (such as -but not limited to: indigenous vegetation, easement/permit width and rights, construction type, voltage, pruning vs. removal philosophy, environmental restrictions, federal/state/local ordinances, etc.) Right of way maintenance frequency intervals for program component tasks are identified below.IMNT-TRMX-00176 I Rev. 2 (02/07) 1 Page 3 of 12 AUTHORIZED COPY PE Carolinas PE Florida Task 2.4.1.1 Right of Way 1.

Yates Self Assessment of Carolina Power & Light Company's Brunswick Steam Electric Plant for Compliance with Threatened and Endangered Species August 12, 1998 In March 1997, the Ecology Group of Pacific Northwest National Laboratory (PNNL) issued a report to the U.S. Nuclear Regulatory Commission entitled "Threatened and Endangered Species Evaluation for 75 Licensed Nuclear Power Generating Plants" (PNNL-l 1524). The purpose of the report was to evaluate the Nuclear Regulatory Commission's licensing of commercial nuclear generating facilities to determine compliance with the Endangered Species Act of 1973 (ESA).Such an evaluation was necessary because the ESA requires that federal agencies ensure that actions by one another do not jeopardize the species protected under the ESA.The PNNL report included the Brunswick Steam Electric Plant and listed threatened and endangered species that might be impacted by plant activities. The PNNL assigned low, medium, or high priority for follow up regarding the potential for impacts to species at the nuclear facilities. Those facilities with a high-priority ranking were deemed, according to the PNNL report, in need of detailed follow-up evaluations before full ESA compliance can be assured. The Brunswick was given High Priority for sea turtles, manatees, terrestrial species, and other aquatic species.The purpose of this CP&L self assessment is to evaluate the PNNL report to determine what activities by Brunswick personnel need to be considered for compliance with the ESA for any species actually or likely occurring on Company property at the site. Transmission rights-of-way were assessed only to the Company property boundary. Beyond the property boundary, CP&L has easements on power line corridors on land that is privately owned. However, any known locations on power line corridors in North Carolina of rare, threatened, or endangered species are protected by management agreement with the North Carolina Natural Heritage Program.This self assessment was carried out by considering the species identified in the PNNL report, assessing the potential for their actual occurrence at the site, and what activities, if any, need to be considered to prevent such species impact. The CP&L self assessment compared the list of potential species from the PNNL report to the current federally protected species and any considered state threatened, endangered, and special concern species as listed by the North Carolina Natural Heritage Program.The results of the self assessment for the Brunswick Steam Electric Plant are shown in Table 1.This table lists the species of animals and plants identified in the PNNL report, the current U.S.Fish &"Wildlife Service list of protected species for North Carolina, and the species from the natural heritage program for North Carolina. The latter state list identifies species at the county level in which the nuclear facility is located. The status of each species (e.g., whether endangered, threatened, etc.) at the federal or state level is also identified in Table I showing their known occurrence in proximity to the nuclear plants (in some cases adjacent counties), and actions, if any, required to avoid impact to these species.An evaluation was made of the species that reasonably could be impacted by plant activities. The results of the evaluation are provided in Exhibit 1. Recommended actions required of CP&L are also suggested. A proposed modification addition to the Environmental Self-Assessment Program "Other Items" Compliance Checklist is included as Exhibit 2 as a means of continuing this assessment on an on-going basis..Included as Exhibit 3 is the current federally listed plants and animals for North Carolina.Attached as Exhibit 4 is a Literature Review and Sources Used for this self assessment. Summar: The report issued by the PNNL included species of plants and animals that were in part extracted from state natural heritage program lists, and were thus not federally endangered or threatened. For this reason, this CP&L self assessment was expanded to include reviews of currently listed endangered, threatened, special concern species, as well as other species designations made by heritage program staff of North Carolina. While this state list does not carry the same regulatory status as the federal U.S. Fish & Wildlife Service list, it is included in this self assessment to more accurately assess the species of concern. The state listed species have the potential for future federal listing and, hence, they are "candidate species." The self-assessment evaluation of the Brunswick Steam Electric Plant shows there are six federally protected species that could be impacted by Plant operations, facility expansion, or other activities. The results of the assessment show that the only known instances where nuclear plant operations are having an effect on a federally listed species are sea turtles at the Brunswick Steam Electric Plant. In that case, CP&L is currently cooperating' with the Nuclear Regulatory Commission and the National Marine Fisheries under a Section 7 Consultation of the Endangered Species Act. Resolution is expected later in 1998.Ongoing communication, regarding activities that potentially could affect threatened and endangered species, is recommended between plant personnel and personnel in CP&L' s Environmental Service Section, Real Estate Management Section, and the Transmission Department.

The purpose of the report was to evaluate the Nuclear Regulatory Commission's licensing of commercial nuclear generating facilities to determine compliance with the Endangered Species Act of 1973 (ESA).Such an evaluation was necessary because the ESA requires that federal agencies ensure that actions by one another do not jeopardize the species protected under the ESA.The PNNL report included the Harris Nuclear Plant and listed threatened and endangered species that might be impacted by plant activities. The PNNL assigned low, medium, or high priority for follow up regarding the potential for impacts to species at the nuclear facilities. Those facilities with a high-priority ranking were deemed, according to the PNNL report, in need of detailed follow-up evaluations before full ESA compliance can be assured. The Harris was given High Priority for the Cape Fear shiner (a fish), the red-cockaded woodpecker, rare plants, etc.The purpose of this CP&L self assessment is to evaluate the PNNL report to determine what activities by Harris plant personnel need to be considered for compliance with the ESA for any species actually or likely occurring on Company property at the site. Transmission rights-of-way were assessed only to the Company property boundary. Beyond the property boundary, CP&L has easements on power line corridors on land that is privately owned. However, any known locations on power line corridors in North Carolina of rare, threatened, or endangered species are protected by management agreement with the North Carolina Natural Heritage Program.This self assessment was carried out by considering the species identified in the PNNL report, assessing the potential for their actual occurrence at the site, and what activities, if any, need to be considered to prevent such species impact. The CP&L self assessment compared the list of potential species from the PNNL report to the current federally protected species and any considered state threatened, endangered, and special concern species as listed by the North Carolina Natural Heritage Program.The results of the self assessment for the Harris Nuclear Plant are shown in Table 1. This table lists the species of animals and plants identified in the PNNL report, the current U.S. Fish &Wildlife Service list of protected species for North Carolina, and the species from the natural heritage program for North Carolina. The latter state list identifies species at the county level in which the nuclear facility is located. The status of each species (e.g., whether endangered, threatened, etc.) at the federal or state level is also identified in Table I showing their known occurrence in proximity to the nuclear plants (in some cases adjacent counties), and actions, if any, required to avoid impact to these species.An evaluation was made of the species that reasonably could be impacted by plant activities. The results of the evaluation are provided in Exhibit I. Recommended actions required of CP&L are also-suggested. A proposed modification addition to the Environmental Self-Assessment Program "Other Items" Compliance Checklist is included as Exhibit 2 as a means of continuing this assessment on an on-going basis.Included as Exhibit 3 is the current federally listed plants and animals for North Carolina.Attached as Exhibit 4 is a Literature Review and Sources Used for this self assessment. Summar'The report issued by the PNNL included species of plants and animals that were in part extracted from state natural heritage program lists, and were thus not federally endangered or threatened. For this reason, this CP&L self assessment was expanded to include reviews of currently listed endangered, threatened, special concern species, as well as other species designations made by heritage program staff of North Carolina. While this state list does not carry the same regulatory status as the federal U.S. Fish & Wildlife Service list, it is included in this self assessment to more accurately assess the species of concern. The state listed species have the potential for future federal listing and, hence, they are "candidate species." The self-assessment evaluation of the Harris Nuclear Plant shows there is one federally protected species that could be impacted by plant operations, facility expansion, or other activities. Ongoing communication, regarding activities that potentially could affect threatened and endangered species, is recommended between plant personnel and personnel in CP&L's Environmental Service Section, Real Estate Management Section, and the Transmission Department.

File X:\ess\workingd\Inisc\endspHarris.doc Self Assessment of Carolina Power & Light Company's Robinson Steam Electric Plant for Compliance with Threatened and Endangered Species August 12, 1998 In March 1997, the Ecology Group of Pacific Northwest National Laboratory (PNNL) issued a report to the U.S. Nuclear Regulatory Commission entitled "Threatened and Endangered Species Evaluation for 75 Licensed Nuclear Power Generating Plants" (PNNL-1 1524). The purpose of the report was to evaluate the Nuclear Regulatory Commission's licensing of commercial nuclear generating facilities to determine compliance with the Endangered Species Act of 1973 (ESA).Such an evaluation was necessary because the ESA requires that federal agencies ensure that actions by one another do not jeopardize the species protected under the ESA.The PNNL report included the Robinson Steam Electric Plant and listed threatened and endangered species that might be impacted by plant activities. The PNNL assigned low, medium, or high priority for follow up regarding the potential forimpacts to species at the nuclear facilities. Those facilities with a high-priority ranking were deemed, according to the PNNL report, in need of detailed follow-up evaluations before full ESA compliance can be assured. The Robinson facility was given Moderate-to-High Priority for the occurrence of the red-cockaded woodpecker and other species.The purpose of this CP&L self assessment is to evaluate the PNNL report to determine what activities by Robinson plant personnel need to be considered for compliance with the ESA for any species actually or likely occurring on Company property at the site. Transmission rights-of-way were assessed only to the Company property boundary. Beyond the property boundary, CP&L has easements on power line corridors on land that is privately owned.This self assessment was carried out by considering the species identified in the PNNL report, assessing the potential for their actual occurrence at the site, and what activities, if any, need to be considered to prevent such species impact. The CP&L self assessment compared the list of potential species from the PNNL report to the current federally protected species and any considered state threatened, endangered, and special concern species as listed by the South Carolina Heritage Trust Program.The results of the self assessment for the Robinson Steam Electric Plant are shown in Table 1.This table lists the species of animals and plants identified in the PNNL report, the current U.S.Fish & Wildlife Service list of protected species for South Carolina. The latter state list identifies species at the county level in which the nuclear facility is located. The status of each species (e.g., whether endangered, threatened, etc.) at the federal or state level is also identified in Table 1 showing their known occurrence in proximity to the nuclear plants (in some cases adjacent counties), and actions, if any, required to avoid impact to these species. An evaluation was made of the species that reasonably could be impacted by plant activities. The results of the evaluation are provided in Exhibit 1. Recommended actions required of CP&L are also suggested. A proposed modification addition to the Environmental Self-Assessment Program "Other Items" Compliance Checklist is included as Exhibit 2 as a means of continuing this assessment on an on-going basis.Included as Exhibit 3 is the current federally listed plants and animals for South Carolina.Attached as Exhibit 4 is a Literature Review and Sources Used for this self assessment. Summgar: The report issued by the PNNL included species of plants and animals that were in part extracted from state heritage trust program lists, and were thus not federally endangered or threatened. For this reason, this CP&L self assessment was expanded to include reviews of currently listed endangered, threatened, special concern species, as well as other species designations made by the S. C. Heritage Trust program staff of South Carolina. While this state list does not carry the same regulatory status as the federal U.S. Fish & Wildlife Service list, it is included in this self assessment to more accurately assess the species of concern. The state listed species have the potential for future federal listing and, hence, they are "candidate species." The self-assessment evaluation of the Robinson Steam Electric Plant shows there is one federally protected species that could be impacted by plant operations, facility expansion, or other activities. Ongoing communication, regarding activities that potentially could affect threatened and endangered species, is recommended between plant personnel and personnel in CP&L's Environmental Service Section, Real Estate Management Section, and the Transmission Department.

SUMMARY

Harris Reservoir supplies makeup water to the closed-cycle cooling system for the Harris Nuclear Plant. The Harris Nuclear Plant discharges primarily cooling tower blowdown along with low volume waste discharges into the reservoir near the main dam.Nutrient concentrations, including total phosphorus and total nitrogen concentrations, remained stable for the reporting period (1996-2000) and were in an acceptable range for a productive reservoir in this., area. The concentrations of most chemical constituents did not exhibit any consistent statistically significant temporal changes and were in ranges that were not considered detrimental to the biological community. Bluegill, redear sunfish, largemouth bass, and black crappie dominated the fish community in Harris Reservoir during 2000. Annual catch rates for bluegill, largemouth bass, and black crappie were similar to catch rates in previous years while the 2000 annual catch rate for redear sunfish was generally greater than previous years. Length-frequency distributions indicated good reproduction with multiple size groups present for all species. The largemouth bass population remains balanced with a large percentage of larger fish present in the population. Hydrilla stands reaching the surface of the water were not observed in the intake canal in Harris Reservoir or in the littoral zone of the auxiliary reservoir during 2000. The attempt to control hydrilla in the auxiliary reservoir by releasing grass carp in the autumns of 1994, 1996, and 1997 appears to have been effective in reducing the quantity and area covered by this vegetation. Carolina Power & Light Company Environmental Services Section Carolina Power & Light Company Environmental Services Section V Harris Nuclear Plant 2000 Environmental Monitoring Report HARRIS NUCLEAR PLANT 2000 ENVIRONMENTAL MONITORING REPORT Reservoir Description Harris Reservoir, located in Chatham and Wake Counties, North Carolina, was created by impounding Buckhorn Creek, a tributary of the Cape Fear River (Figure 1). The main body of Harris Reservoir has a surface: area of 1680 ha; the auxiliary reservoir has a surface area of 130 ha. The main reservoir has a maximum depth of 18 m, a mean depth of 5.3 m, a volume of 8.9 X 107 M 3 , a full-pool elevation of 67.1 m National Geodetic Vertical Datum (NGVD), and an average residence time of 28 months. The reservoir began filling in December 1980 and full-pool elevation was reached in February 1983. The 64.5-km shoreline is mostly wooded and the 183.9-km2 drainage area is mostly rolling hills with land used primarily for forestry and agriculture. The conversion of areas from forestry or agricultural purposes to residential uses continued in many areas of the drainage.Harris Reservoir was constructed to supply cooling tower makeup and auxiliary reservoir makeup water to the 900-MW Harris Nuclear Plant, which began commercial operation in May 1987. In 1986 the bottom waters of the reservoir near the main dam began receiving National Pollutant Discharge Elimination System (NPDES)-permitted wastewater discharges from the power plant cooling tower. Tributaries also receive NPDES-permitted discharges from the Harris Energy and Environmental Center and from wastewater treatment plants at Apex and Holly Springs. The reservoir is a source of drinking water for some Company employees. Objectives The primary objectives of the 2000 Harris Nuclear Plant non-radiological environmental monitoring program were to: (1) assess the reservoir's overall water quality, (2) identify any natural or power plant-induced effects on the water quality in the reservoir, (3) document the introduction and expansion of nonnative plant and animal populations in the reservoir, and (4)demonstrate the existence of a reasonable recreational fishery. These objectives have also been addressed in previous annual monitoring reports with the most recent detailed in CP&L 1996, 1997, 1998, 1999, and 2000.CaroinaPowe & igh ComanyEnvronmnta Sevice Setio Carolina Power & Light Company Environmental Services Section 1 Harris Nuclear Plant 2000 Environmental Monitoring Report Methods The 2000 environmental program included monitoring the reservoir's: (1) limnological characteristics (water quality, water chemistry, and chlorophyll a), (2) distribution of aquatic vegetation, (3) possible introductions of the zebra mussel and the quagga mussel, and (4)fisheries community. Simpling methods, data summaries, and statistical analyses for data collected during 2000 were similar to those used for data collected during 1999 (CP&L 2000)(Tables 2 and 3). Trend analyses of the data were evaluated for the most recent five years of monitoring (1996-2000) for most programs. Supporting data summaries and appropriate statistical analyses were used to describe and interpret the environmental quality of the reservoir (Table 3). Electrofishing data were not collected from 1992 to 1994 and from 1996 to 1998.Therefore, annual catch rates for 2000 data were compared to data from 1988 to 1991 and 1995.Three stock assessment indices were used as indicators of a balanced largemouth bass population (Gablehouse 1984). These indices include: Proportional Stock Density (PSD), the percentage of all fish _ 300 mm; Relative Stock Density for preferred length (RSDp), the percentage of all fish>_ 380 mm; and Relative Stock Density for memorable length (RSDM), the percentage of all fish_ 510 mm.All analytical testing, except total phosphorus analyses, completed in support of the Harris Reservoir environmental monitoring program was performed by testing laboratories that are certified by the N. C. Division of Water Quality's Laboratory Certification Program to perform water and wastewater testing. Perkins Limnological Consulting, LLC, a vendor approved by CP&L for this testing, conducted total phosphorus analysis. The accuracy and precision of laboratory analyses of water chemistry data were determined with analytical standards, spikes, and replicates. Quality assurance information including the accuracy and percent recovery of water chemistry standards are available upon request. In this report where concentrations were less than the laboratory-reporting limit, the concentrations were assumed to be at one-half the reporting limit for the calculation of the mean. Where statistically significant results were reported, a Type I error rate of 5% = 0.05) was used and Fisher's protected least significant difference test was applied to determine where significant differences in mean values occurred.Carolina Power & Light Company Environmental Services Section Carolina Power & Light Company Environmental Services Section 2 Harris Nuclear Plant 2000 Environmental Monitoring Report Harrs Nclea Plnt 000 nvionmetalMontorig Rpor Cary B'ranch'0* .. .: .F L, Kilometers 1 Miles 2 m Figure 1.

Program Method Water quality Water chemistry Phytoplankton Chlorophyll a Electrofishing Zebra mussel Aquatic vegetation survey Temperature, dissolved oxygen, pH, and specific conductance were measured with calibrated YSI multiparameter instruments and YSI dissolved oxygen meters.Measurements were taken from surface to bottom at 1-m intervals. Water clarity was measured with a Secchi disk.Surface (Stations E2, H2, P2, and S2) and bottom samples (Station E2) were collected in appropriate containers, transported to the laboratory on ice, and analyzed according to accepted laboratory methods.Equal amounts of water from the surface, the Secchi disk transparency depth, and twice the Secchi disk transparency depth were obtained with a Van Dom sampler and mixed in a plastic container. A 250-ml sub sample was taken and preserved with 5 ml of 'M3" fixative.Equal amounts of water from the surface, the Secchi disk transparency depth, and twice the Secchi disk transparency depth were obtained with a Van Dom sampler, placed in a plastic container and mixed, then a 1000-ml sub sample was collected in a dark bottle. All samples were placed on ice and returned to the laboratory. In the laboratory a 250-ml sub sample was analyzed according to Strickland and Parsons (1972) and APHA (1995).Fifteen-minute samples were collected at each station using a Smith-Root Type VI-A equipped, Wisconsin-design electrofishing boat with pulsed DC current. Fish were identified, measured to the nearest mm, weighed to the nearest gram, examined for the presence of disease and deformities, and released.The dock at the Holleman's boat ramp, or water quality station marker buoys were visually inspected for the presence of mussels during routine water quality monitoring. Portions of the shoreline and/or littoral zone of the Harris Plant main reservoir intake canal and auxiliary reservoir were systematically surveyed by boat to document the presence of aquatic vegetation specifically hydrilla and creeping water primrose.Carolina Power & Light Company Environmental Services Section Carolina Power & Light Company Environmental Services Section 5 Harris Nuclear Plant 2000 Environmental Monitoring Report Table 3.

Monitoring Report RESULTS OF ENVIRONMENTAL MONITORING AT HARRIS RESERVOIR DURING 2000 Limnology Temperature and Dissolved Oxygen* Harris Reservoir waters at all reservoir stations (except Station S2) were strongly stratified during July and were either well mixed or very weakly stratified during January, May, and November, 2000 (Appendix 1). During July, portions of the hypolimnion were anoxic (i.e., conditions where dissolved oxygen concentrations are less than I mg/liter) at Stations E2, H2, and P2 (Appendix 1). Station S2, which is comparatively shallow, exhibited a small decrease in oxygenation near the bottom during May and July but otherwise was well mixed and oxygenated for the remainder of the year. A bottom-water oxygen decline is typical at the deeper stations during the warm summer months in Harris Reservoir and in other southeastern productive water bodies when well-defined thermoclines develop and block bottom waters from mixing with the upper, more oxygenated waters.Water Clarity (Secchi disk transparency, Solids, and Turbidity)

• The Secchi disk transparency depth (a water clarity indicator) generally increased with linear distance from the headwater region (Station S2) to the dam during January and May 2000 (Appendix 1). This spatial pattern is typical of patterns observed during 1995 through 1997 and 1999. However, headwaters were much clearer than downstream stations during November of 2000. Although there monthly spatial differences, there were no significant differences in the annual mean Secchi disk transparencies between stations during 2000." While statistical differences were noted in the reservoir-wide annual mean Secchi disk transparency values during the period 1996 to 2000, these variations were considered to minor and not biologically important (Appendix 3)." There were no significant spatial trends for solids (i.e., total solids, total dissolved solids, and total suspended solids) or turbidity for Harris Reservoir surface waters during 2000 (Appendix 2).Carolina Power & Lig ht Company Environmental Services Section 7 Harris Nuclear Plant 2000 Environmental Monitoring Report* The annual mean total solids and total dissolved solids were statistically variable during the 1996 through 2000 observation period (Appendix 3). These minor fluctuations were not biologically important.

Chlorophyll a* During 2000, mean chlorophyll a concentrations (an indicator of algal biomass) in Harris Reservoir continued to be indicative of moderate to high biological productivity. However, unlike concentrations measured in 1997 and 1998, no chlorophyll a concentration exceeded the North Carolina water quality standard of 40 ptg/liter during 2000 (NCDEM 1992). There were no significant spatial differences in chlorophyll a concentrations during 2000 (Appendix 2).* While statistically significant fluctuations in annual mean chlorophyll a concentrations were observed during the 1996 through 2000 period, no trends were indicated (Appendix 3).Nutrients and Total Organic Carbon (surface waters)* There were no significant spatial differences among stations for mean nutrient (i.e., phosphorus, ammonia-N, nitrate + nitrite-N, and total nitrogen) and total organic carbon concentrations in Harris Reservoir during 2000 (Appendix 2).Also, there were no statistically significant temporal trends for nutrient concentrations and 1996 to 2000 (Appendix 3). Total organic carbon concentrations varied significantly during the observations period but were not considered biologically important. Specific Conductance, Ions, and Hardness (surface waters)* There were no biologically meaningful spatial differences in conductivity, ion concentration (except chloride), or hardness during 2000 (Appendix 2)." Annual mean chloride and sulfate concentrations significantly increased during 2000 compared to concentrations during 1999. These values represented only small changes and were similar to concentrations observed during other years within the five-year period from 1996 to 2000 (Appendix 3).Carolna Pwer &Ligh Compny Evironenta Serice eto Carolina Power & Light Company Environmental Services Section 8 Harris Nuclear Plant 2000 Environmental Monitoring Report* The annual reservoir mean conductivity was similar among years during the period 1996-2000 (Appendix 3).pH and Total Alkalinity" The median pH in the surface waters of Harris Reservoir was 7.2 during 2000 (Appendix 1).* In 2000 total alkalinity concentrations were not statistically different among stations (Appendix 2). The annual mean total alkalinity concentrations fluctuated significantly but with no consistent pattern during the 1996 to 2000 comparison period (Appendix 3).Trace Metals and Metalloids (surface waters)* Overall, the concentrations of trace elements in Harris Reservoir were generally low in 2000 with most concentrations less than or near their respective laboratory reporting limits (Appendices 2 and 5). No spatial trends in any of measure trace elements were observed during 2000 (Appendix 2). Aluminum concentrations ranged from < 50 to 440 jLg/liter during 2000 with the greater value recorded in a headwater region where aluminum concentrations may have been influenced by upstream watershed sources (Appendices 2 and 5)." Copper exhibited statistically significant variations in surface waters but no true temporal trend was observed during the 1996 to 2000 comparison period (Appendix 3). No other temporal differences were observed among trace element concentrations in either surface or bottoms waters of Harris Reservoir for the period 1996 to 2000 (Appendix 3 and 4).Chemical Constituents in the Bottom Waters at Station E2" The concentrations of most chemical constituents in the bottom waters of the deepest station (Station E2) near the dam and Harris Plant blowdown pipe were within typical ranges expected for a productive, southeastern reservoir and were not considered detrimental to the biological community (Appendix 4).* Only chlorides showed statistical variations among years in the bottom waters at Station E2, but these differences were minor and did not represent a temporal trend (Appendix 4).Carolina Power & Light Company Environmental Services Section 9 Harris Nuclear Plant 2000 Environmental Monitoring Report Sulfate and aluminum concentrations appeared to increase dramatically during May 2000 in the bottom waters of Station E2 (Appendix 5). Also, marked shifts in alkalinity, total nitrogen, ammonia, and total phosphorus concentrations during July of 2000 in the bottom waters at Station E2 were noted. These very notable shifts in the magnitude of chemical concentrations in the bottom waters is typical is Harris Reservoir each year and believed to be related to stratification processes and possibly intermittent blowdown from the power plant.Since this chemical shifting generally occurs in the deepest part of the lake and primarily in anoxic waters, it was not considered to be biologically detrimental to aquatic community. Biofouling Monitoring Surveys* No zebra mussels (Dreissena polyinorpha) or quagga mussels (D. bugensis), potentially serious biofouling organisms to power plant operations, were .found in Harris Reservoir or the auxiliary reservoir during 2000. Zebra mussels and quagga mussels are not expected to thrive in Harris Reservoir because concentrations of alkalinity, calcium, total hardness, and pH are sub optimal for mussel growth and reproduction (Claudi and Mackie 1993).Fisheries* Twenty fish species were collected with quarterly electrofishing sampling during 2000 (Appendix 6). For the second year in a row, a Morone spp. (white perch) was collected from Harris Reservoir. Three species collected in 1999--comely shiner, spottail shiner, and yellow bullhead--were not collected during 2000 ,(CP&L 2000). These species have historically been numerically minor in Harris Reservoir and the absence in the electrofishing samples were considered to be related to geartype selectivity and/or random spatial distribution.

• Bluegill, redear sunfish, largemouth bass, and black crappie comprised approximately 82% of the mean number per hour collected (Appendix 6). While black crappie catch appeared to have tapered off slightly during 2000, these recreationally important species have historically dominated electrofishing samples from Harris Reservoir (Appendix 7 and CP&L 2000).* Significant differences in the mean catch rate between transects were observed for redear sunfish, largemouth bass, and total catch. As the following table of log-e transformed mean catch rates indicates, significantly more redear sunfish were collected from Transects E and H Carolina Power & Light Company 10 Environmental Services Section Harris Nuclear Plant 2000 Environmental Monitoring Report compared to Transects P, S, and V (means with different superscripts are significantly different).

Largemouth bass exhibited uniform catch rates reservoir-wide except at Transect H where the catch rates were lower compared to other transects. The catch rates of other recreational species were uniform among transects. Transect Species E H P S V Redear sunfish 4.3a 4.7a 3.Oc 2.2c 3.3" Largemouth bass 3.0" 2.3b 3.3a 3.1a 3.3a* The length-frequency distribution for bluegill indicated strong recruitment during 2000 (Appendix 8). Additionally, there were adequate numbers of older, larger fish to support a recreational fishery. The mean relative weight (84) of bluegill collected during 2000 was less than optimal (100 = optimum) but was consistent with the range that might be expected under relatively high population densities (Appendix 9).The annual mean electrofishing catch rate for redear sunfish of 67 fish per hour, while somewhat lower than the 1995 and 1999 values, was still in a range substantially greater than the catches of the late 1980s and early 1990s (Appendix 7). Similar to previous years, the length-frequency distribution for redear sunfish indicated a low reproductive success rate during 2000 (Appendix 8). However, the relatively high mean electrofishing catch rate, increasing population size in recent years, and the presence of older, larger fish in the population indicate a viable redear sunfish fishery exists in Harris Reservoir. Similar to bluegill, the less than optimal mean relative weight (78) was in the range consistent with a relatively large population density (Appendix 9).* The annual mean electrofishing catch rate for largemouth bass of 27 fish per hour was within the range reported for quarterly data from 1988 through 1999 (Appendix 7). The values for Proportional Stock Density (PSD) and Relative Stock Density preferred length (RSDp)(Appendix

8) were consistent with objectives for a large bass management strategy (Gablehouse 1984; Willis et al. 1993). The management objective for the largemouth bass population is for the reservoir to contain a large number of big bass equating to a PSD in the range of values from 50 to 80 and an RSDp in the range from 30 to 60. Also, the relative Carolina~

The mean relative weight of largemouth bass collected during 2000 was 94 indicating a healthy, robust body conditions for the average fish (Appendix 9).* No disease outbreaks were noted in Harris Lake during 2000. However, a small number (approximately

20) of dead 6-10 pound largemouth bass were reported during the week following the 4 th of July weekend of 2000. During that weekend, multiple bass tournaments and heavy fishing pressure occurred.

The mortality observed was thought to be related to delayed mortality from improper handling techniques associated with catch and release prIactices.

• Habitat improvements (Christmas tree reefs) were conducted in the Harris Plant auxiliary reservoir during 2000. Limited fishing.is allowed in the auxiliary reservoir.

Aquatic Vegetation" A visual survey revealed no stands of hydrilla (Hydrilla verticillata), a non-native submersed plant, reaching the surface of the water of the intake canal in Harris Reservoir during 2000.However, creeping water primrose (Ludwigia uruguayensis) was noted along both sides of the canal and existed in amounts similar to those observed during 1999. Although creeping water primrose was well established in this region, no impacts to the Harris Plant have occurred nor are they expected because of the low velocity of water drawn from the main reservoir into the cooling tower makeup water intake structure.

• During November 2000 large hydrilla stands extending to the water surface were observed in the littoral zone at Station S. At Station E hydrilla and creeping water primrose dominated the aquatic plant community.

Small amounts if Eleocharis sp. and Utricularia sp. were observed. No significant quantities of aquatic vegetation were observed in the auxiliary reservoir during 2000. The continued presence of grass carp (Ctenopharyngodon idella)from previous stockings has provided adequate control of potential nuisance overgrowth stands in the auxiliary reservoir. Carolina Power & Light Company Environmental Services Section Carolina Power & Light Company Environmental Services Section 12 Harris Nuclear Plant 2000 Environmental Monitoring Report CONCLUSIONS During 2000, the Harris Reservoir continued to show characteristics of a typical southeastern, biologically productive reservoir with seasonally occurring oxygen-deficient subsurface waters, elevated nutrient concentrations, and an abundance of rooted shallow-water aquatic plants.The environmental monitoring program conducted during 2000 continued to provide an assessment of the effects of the Harris Nuclear Plant's operation on the various components of the aquatic environment. Most key indicators of the environmental quality in Harris Reservoir were unchanged from the previous five years. Nutrient concentrations have been a concern in Harris Reservoir since phosphorous and nitrogen concentrations increased rapidly in the late 1980s and early 1990s. Water quality assessments determined that nutrient concentrations have remained stable since 1995 and at levels acceptable for southeastern, productive reservoirs. Assessments of other water quality parameters, including solids, turbidity, total organic carbon, ions (calcium, chloride, magnesium, sodium, and sulfate), total alkalinity, hardness, and metals, indicate few if any consistent statistically significant spatial or temporal trends with none of these variables at concentrations which would be detrimental to the aquatic community. No nuisance algal blooms, as indicated by chlorophyll a concentrations, or exotic mussels were detected in the main reservoir during 2000. Reservoir-wide chlorophyll a concentrations demonstrated no consistent statistically significant temporal trend for the period 1996-2000. Based on surveys conducted during 2000, no stands of the aquatic plant, hydrilla, extending to the surface of the water were observed in the littoral zone of the intake canal of the main reservoir. The reduced size and extent of aquatic vegetation stands in the auxiliary reservoir indicates that grass carp released in the fall of 1994, 1996, and 1997 continued to control the amount and area coverage of hydrilla during 2000. No operational impacts have occurred at the Harris Nuclear Plant because of aquatic vegetation biofouling. Bluegill, redear sunfish, and largemouth continued to dominate the fishery in Harris Reservoir during 2000. Black crappie catches were slightly lower that usual for 2000. Results indicate the presence of a balanced largemouth bass population exhibiting strong reproduction and the presence of a large percentage of older, larger fish. Abundant forage species such as shad and other sunfish have resulted in very healthy, robust body condition for largemouth bass.Carolina Power & Light Company 13 Environmental Services Section Harris Nuclear Plant 2000 Environmental Monitoring Report REFERENCES Anderson, R. 0., and R.

SUMMARY

Harris Reservoir supplies makeup water to the closed-cycle cooling system for the Harris Nuclear Plant, The Harris Nuclear Plant discharges primarily cooling tower blowdown along with low volume waste discharges into the reservoir near the main dam.Harris Reservoir continued to show qualities of a typical, biologically productive, southeastern reservoir in 2002. Nutrient concentrations, including total phosphorus and total nitrogen concentrations, remained similar torecent years and were in an acceptable range for a productive reservoir in this area.Bluegill,. redear sunfish, largemouth bass, and black crappie dominated the fish community in Harris Reservoir during 2002. Annual catch rates for bluegill and largemouth bass were similar to catch rates in previous years while 'the annual catch rates for black crappie and redear sunfish were greater than in previous years. Bluegill and largemouth bass were represented by multiple size groups and an abundance of small fish indicated good reproduction. Young redear sunfish were less common in samples but the increasing abundance of this species in recent years indicated sufficient reproduction. The largemouth bass population remained balanced with a large percentage of larger fish present in the population. Hydrilla stands reaching the surface of the water were observed in the intake canal in Harris Reservoir during 2002. However, no fouling of the plant intake screens occurred. No stands of hydrilla were observed in the littoral zone of the auxiliary reservoir during 2002. The attempt to control hydrilla in the auxiliary reservoir by releasing grass carp appears to have been effective in reducing the quantity and area covered by this vegetation. Ornnra.ce

The main body of Harris Reservoir has a surface area of 1680 ha; the auxiliary reservoir has a surface area of 130 ha. The main reservoir has a maximum depth of 18 m, a mean depth of 5.3 m, a volume of 8.9 x. 107 mi 3 , a ful-pool elevation of 67.1 m National Geodetic Vertical Datum (NGVD), and an average residence time of 28 months. The reservoir began filling in December 1980 and full-pool elevation was reached in February 1983. The 64.5-km shoreline is mostly wooded and the 183.9-km 2 drainage area is mostly rolling hills with land used primarily for forestry and agriculture.

The conversion of areas from forestry or agricultural purposes to residential uses continues in many areas of the drainage.Harris Reservoir was constructed to supply cooling tower makeup and auxiliary reservoir makeup water to the 900-MW Harris Nuclear Plant, which began commercial operation in May 1987. In 1986 the bottom waters of the reservoir near the main: dam began receiving National Pollutant Discharge Elimination System (NPDES)-permitted wastewater discharges from the power plant cooling tower. Tributaries also receive NPDES-permitted discharges from the Harris Energy and Environmental Center and from wastewater treatment plants at Apex and Holly Springs. The reservoir is a source of drinking Water for Progress Energy employees at the Harris Nuclear Plant and the Harris Energy and Environmental Center.Objectives The primary objectives of the 2002 Harris Nuclear Plant non-radiological environmental monitoring program were to: (1) assess the reservoir's overall water quality, (2) identify any natural or power plant-induced effects on the water quality in the reservoir, (3) document the introduction and expansion of nonnative plant and animal populations in the reservoir, and (4)demonstrate the existence of a reasonable recreational fishery. These objectives have also been addressed in previous annual monitoring reports with the most recent detailed in CP&L 1998., 1999, 2000, 2001, and 2002. Harr is Nuclear Plant 2002 Environmental Monitoring Report Methods The Hahris Nuclear Plant environmental program for 2002 included monitoring the reservoir's: (1) limnnological characteristics (water quality, water chemistry, and phytoplankton), (2) fisheries community, (3). possible introductions of the zebra and quagga mussels, and (4) distribution of aquatic vegetation. Sampling methods and statistical analyses for data collected during 2002 were similar to those used for data collected during 2001 (CP&L 2002) (Tables 2 and 3).Supporting data summaries and appropriate statistical analyses were used. to describe and interpret the environmental quality of the reservoir (Table 3). A list of common and scientific names of species in this report is provided (Table 4). Three stock assessment indices were used as indicators of a balanced largemouth bass population (Gablehouse 1984). These indices include: Proportional Stock Density (PSD), the percentage of fish t 300 mm; Relative Stock Density for preferred length (RSDp), the percentage of fish k 380 mm; and Relative Stock Density for memorable length (RSDm), the percentage of fish ; 510 mm. Only fish greater than the minimum stock length ( *200 mm) were included in these calculations. All analytical testing completed in support of the Harris Reservoir environmental program was performed by appropriate laboratories which were qualified to perform water and wastewater testing. The accuracy and precision of laboratory analyses of water chemistry data were determined with analytical standards, spikes, and replicates. Quality assurance information including the accuracy and percent recovery of water chemistry standards are available upon request. In this report where concentrations were less than the laboratory-reporting limit, the concentrations were assumed to be at one-half the reporting limit for the calculation of the mean.Where statistically significant results were reported, a Type I error rate of 5% (., = .0.05) was.used and Fisher's protected least significant difference test was applied to determine where significant differences in mean values occurred.IT~ ..~ -~ O nn'Oefn Harris Nuclear Plant 2002 Environmental Monitoring Report Oak Creek A'.Cary Branch I,, B -.I CD I ~Buckhom'.

Measurements were taken from surface to bottom at I-m intervals. Water clarity was measured with a Secchi disk.Surface water samples were collected in appropriate containers, transported to the laboratory on ice, and analyzed according to accepted laboratory methods.Equal amounts of water from the surface, the Secchi disk transparency depth,, and twice the Secchi disk transparency depth were obtained with a Van Dorn sampler and mixedin a plastic. container. A 250-ml sub sample was. taken and preserved with 5 ml of "MY' fixative.Equal amounts of water from the surface, the Secchiidisk transparency depth, and twice the Secchi disk transparency depth were obtained with a Van Dom sampler and mixed in a plastic, container.. A 1000-ml sub sample was collected in a dark.bottle, placed. on. ice, and returned.to. the laboratory. In the laboratory a 250-ml sub sample was analyzed according to Strickland and Parsons (1972) and APHA (1995).Fifteen-minute samples. were collected at each station using a Smith-Root Type VI-A, 5.0 GPP, or 7.5 GPP equipped,. Wisconsin-design electrofishing boat with pulsed DC current. Fish were identified to species, measured to the nearest. mm, weighed to the nearest gram, examined for the presence of disease and deformities, and released.The dock at the Holleman's boat ramp or water quality station marker buoys were Visually inspected for the presence of mussels during routine water quality monitoring., Portions of the shoreline and/or littoral zone of the Harris Plant main reservoir intake canal and auxiliary reservoir were systematically surveyed by boat to document the presence of aquatic vegetation, specifically hydrilla and water primrose.

Portions of the hypolimnion just above the reservoir bottom were anoxic (i.e., conditions where dissolved oxygen concentrations are less than I mg/liter)during May and July at the deeper stations (Stations E2. H2, and P2) (Appendix 1). During July water at six meters and below was anoxic at these stations and water near the bottom at Station S2 Was also anoxic. A bottom-water oxygen decline is typical at the deeper stations during the warm summer months in Harris Reservoir and in other productive southeastern water bodies.Water Clarity (Secehi Disk Transparency. Total Dissolved Solids, and Turbidity) e Secehi disk transparency depths were similar among stations during January, May, and July with depths ranging from 1.2 to 1.7 m (Appendix

1) and the maximtun difference among stations for any sampling date only 0.5 m. During November, the Secchi disk transparency depth at S2 in the White Oak Creek arm was only 0.8 m. There were no significant differences in the amnual mean Secchi disk transparencies among stations during 2002 (Appendix 2).* There were.. no significant spatial trends for total dissolved solids or turbidity during 2002 (Appendix 2). Based on consistently low concentrations of total solids and total suspended solids in the historical database, sampling for these variables was discontinued in 2002.Turbidity was generally low at all stations with values ranging from 1.3 to 7.2 NTU; the only exception was the November sample at Station S2 where turbidity was 18 NTU.r.------------*--.

Chlorophyll a concentrations were highest at, all stations in the May samples and averaged 12 g/l iter reservoir-wide for 2002 (Appendix 2). The greatest recorded chlorophyll a concentration %was:25 jig/liter at Station H2 in May. Because chlorophyll a concentrations did not exceed ithe North Carolina water quality standard of 40 Vg/liter (NCDEM 1992), the collected phytoplankton wasr not identified. Chlorophyll a concentrations at Station -2 were.significantly greatei than the concentrations at Stations E2 and S2; concentrations. at Station P2 were intermediate between Stations H2and E2.Nutrients and T otal Organic Carbon* There were no significant spatial differences among. stations for mean nutrient (i.e., total phosphorus, ammonia-N, nitrate + nitrite-N, and total nitrogen) and total organic carbon concentrations in Harris Reservoir during 2002 (Appendix 2).Specific Conductance, Ions, and Hardness* There were no significant spatial differences in conductivity, ion concentration (calcium, chloride, magnesium, sodium, and.sulfate) or hardness during 2002 (Appendix 2).pH and Total Alkalinity

• The median pH in the surface waters of Harris Reservoir was 7.4 during 2002 (Appendix 1).Surface pH values were highest at all stations during July when values ranged from 8.1 to 8.5." In 2002 total alkalinity concentrations were not statistically different among stations (Appendix 2).Trace Metal -Copper* Based on consistently low concentrations of aluminum, cadmium, and mercury in the historical database, sampling for these trace elements, was discontinued in 2002. All measured concentrations of copper were low (< 2.5 pg/liter) in 2002 with an annual reservoir mean of 1.6 ptg/liter (Appendix 2).. No spatial trends were observed.C) y.nv..C nnn , .~ r g nn m n .I Qnjic nt 0--- C-- 1--1;-QnmrjýýO Qnýfi^n Harris Nuclear Plant 2002 Environmental Monitoring Report Fisheries* Nineteen fish species. were collected with quarterly electrofishing sampling during 2002 (Appendix 3). White perch, a species not collected in Harris Reservoir before 1999, was collected at two transects in 2002. Four common carp, a species native to Asia, were collected at Transect V during 2002. This introduced species was present in the Cape Fear River before Harris Reservoir was created but had not been collected in the reservoir before 2000, when one common carp was collected at this same transect.

White perch and common carp will likely become more abundant and widespread in Harris Reservoir in the near future.Redbreast sunfish and whfite crappie were not collected during 2002, but were collected in 2000 (CP&L 2001). These species have historically been uncommon in Harris Reservoir and their absence in electrofishing samples was considered to be related to gear selectivity and/or random spatial distribution.

• The reservoir-wide average of 322 total fish per hour during 2002 (Appendix

3) exceeded reservoir means for quarterly electrofishing samples from 1988 to 2000 (CP&L 2001).Reservoir-wide catch per hour values in 2002 for four common species (black crappie, redear sunfish, threadfin shad, and golden shiner).exceeded the maximum catch rateswith quarterly electrofishing measured from 1988 to 2000 (CP&L 2001)." Four sunfish species (bluegill, redear sunfish, largemouth bass, and black crappie) comprised 80% of the mean number per hour collected in Harris Reservoir during 2002 (Appendix 3).By weight, largemouth bass, redear sunfish, bluegill, and gizzard shad were the dominate taxa (Appendix 4)." Redear sunfish catch rates in electrofishing samples differed significantly among transects (Appendix 3). Significantly more redear sunfish were collected at Transect H than at all other transects.

The catch rates of other recreationally important species were not significantly different among transects. Comparisons of redear sunfish weight per hour revealed a similar pattern among transects (Appendix 4). With the exception of golden shiner, there were, no significant differences in weights among transects for any of the other species assessed.ý ONUMOWN Harris Nuclear Plant 2002 Environmental Monitoring Report* The length-frequency distribution for bluegill indicated strong recruitment during. 2002 (Appendix 5). Additionally, there were adequate numbers of older, larger fish to support a recreational fishery. The mean relative weight of bluegill (n = 1,023, fish 80 mm TL)collected during 2002 was 82. This was less than optimal (100 = optimum), but was consistent with the range that might be expected under relatively high population densities. The annual mean:electrofishing catch rate for redear sunfish of 92 fish per hour (Appendix 3)was the highest ever for quarterly sampling (CP&L 2001).and continued an increasing trend in redear sunfish catch rates. Similar to previous years, the length-frequency distribution for redear sunfish indicated low reproductive success during 2002 (Appendix 5). However, the relatively high mean electrofishing catch, rate, increasing population size in recent years, and the presence: of older, larger fish in the population indicated that a viable re.dear sunfish fishery exists in Harris Reservoir. Similar to bluegill, the less than optimal mean relative weight (77). for redear sunfish (n = 916, fish z 80 mm TL) was in the range consistent with a relatively large population density.The annual mean electrofishing catch rate for largemouth bass of 29 fish per hour was within the range reported for quarterly data from 1988 through 2000 (CP&L 2001).. Proportional Stock Density (PSD) and Relative Stock Density preferred length (RSDp) values of 78 and 50, respectively, were consistent with objectives for a largemouth bass management strategy targeting larger fish (Gablehouse 1984;* Willis et al. .1993). The management objective for Harris Reservoir to contain a large number of big bass equates to a PSD ranging from 50 to 80 and an RSDp in the range of 30 to 60. Also, the Relative Stock Density memorable length index (RSDM) was 5 during 2002, which was in the range (0-10) of values indicating a balanced largemouth bass population. The mean relative weight of largemouth bass collected during 2002 (n = 126, fish 2 15.0. mm TL) was 96, indicating a healthy, robust body condition.

• Largemouth bass length-frequency analysis revealed a large number of bass < 100 mm TL (Appendix 5). Length-frequency analysis for the four sampling periods revealed that the majority of the bass < 100 mm TL were from the 2002 year class. Young-of-Year (YOY)were well distributed among the five transects with each transect contributing at least 10% of the total YOY and Transect P contributing 41% of the YOY. Largemouth bass weight per Harris Nuclear Plant 2002 Environmental Monitoring Report hour ranged from. 3.8 kg/hour at Transect E to 25.0 kg/hour at Transect.

V, which is a restricted area that prohibits angling, access.. However, these differences among transects were not significant (Appendix 4).* No fish kills or disease outbreaks were noted in Harris Reservoir during 2002.e Seven bundles of Christmas trees were added to the reservoir to improve fish habitat near the:fishing pier at Harris Lake County Park.Biofouling Monitoring Surveys* No zebra mussels or quagga mussels, potentially serious biofouling organisms to power plant operations, were found in Harris Reservoir or the auxiliary reservoir during 2002. Zebra and quagga mussels are not expected to thrive in Harris Reservoir because alkalinity, calcium, total hardness, and pH levels are sub-optimal for mussel growth and reproduction (Claudi and Mackie 1993).Aquatic Vegetation

• During November 2002 water hyacinth and water lettuce, two species of invasive aquatic plants new to Harris Reservoir, were found across the reservoir from the Holleman's Crossroads boat ramp at Transect P. Both are free floating vascular plants native to South America that are widely imported for the ornamental pond trade. All observed plants were removed from this location.

A follow-up visual survey later in November failed to locate any additional water hyacinth or water lettuce.* A visual survey for troublesome aquatic vegetation was conducted in the Harris Auxiliary Reservoir, Harris Reservoir main intake canal, and in the Thomas Creek arm during November 2002. No hydrilla was observed in the auxiliary reservoir. These observations indicated that grass carp stocked in 1994, 1996, and 1997 had effectively controlled the abundance of hydrilla in the auxiliary reservoir. The dominant species growing in the main intake canal were hydrilla and water primrose. Both shorelines of the main intake canal were covered with dense stands of Water primrose and appeared to be similar in density and coverage area to previous years. Hydrilla in the intake canal and in the Thomas Creek area ... .. .... .. ... .Harris Nuclear Plant 2002 Environmental Monitoring Report just outside the intake canal was relatively less abundant in 2002 than in 2001, possibly due to drought conditions throughout most of 2002. Similar levels of hydrilla growth in the past have had no effect on Harris Nuclear Plant operations.

• No impacts to Harris Nuclear Plant operations from aquatic vegetation occurred during 2002.CONCLUSIONS During 2002, Harris Reservoir continued to typify a biologically productive southeastern reservoir with seasonally occurring oxygen-deficient subsurface waters, elevated nutrient concentrations, abundant rooted, shallow-water aquatic plants, and a sunfish dominated fishery.The environmental monitoring:

program conducted during 2002 continued to provide an assessment of the effects of the Harris Nuclear Plant's operation on the various components of the aquatic environment. Most key indicators of the environmental quality in Harris Reservoir were unchanged from previous years. Nutrient concentrations have been a concern in Harris Reservoir since phosphorous and nitrogen concentrations increased rapidly in the late 1980s and early 1990s. Water quality assessments determined that nutrient concentrations have remained stable in recent years and at levels acceptable for productive, southeastern reservoirs. Assessments of other water quality parameters, including total dissolved solids, turbidity, total organic carbon, ions, total alkalinity, hardness, and copper, indicated no consistent, statistically significant spatial trends. None of these variables were at concentrations that would be detrimental to the aquatic community. Bluegill, redear sunfish, and largemouth bass continued to dominate the Harris Reservoir fishery during 2002. Bluegill of various size classes were abundant throughout the reservoir. Redear sunfish were increasingly abundant in Harris Reservoir, especially at the Buckhorn Creek arm and near the dam. Results indicated the presence of a balanced largemouth bass population exhibiting strong reproduction and the presence of a large percentage of larger fish. Abundant forage species have resulted in a very healthy, robust body condition for largemouth bass. White perch and common carp were collected for the first time in Harris Reservoir in recent years but will likely become more abundant and widespread in the near future.Prnnracc Friarri, 1Vfrninný Harris Nuclear Plant 2002 Environmental Monitoring Report No nuisance algal blooms, as indicated by chlorophyll a concentrations or exQtic mussels were detected in the main reservoir during 2002. Water: hyacinth and water lettuce plants were discovered in the main reservoir and all known individuals were removed during November 2002. Hydrilla was relatively less abundant in the intake canal during 2002 compared to 2001.Grass carp continued to control the amount and areal coverage of hydrilla in the auxiliary reservoir during 2002. No operational impacts have occurred at the Harris Nuclear Plant because of aquatic vegetation biofouling. REFERENCES Anderson, R. 0., and R. M. Neumann, 1996.

Prior to commercial operation of the Harris Plant in May 1987, the reservoir was moderately productive. However, the reservoir became more biologically productive when the Harris Plant began discharging, under the auspices of the plant's National Pollutant Discharge Elimination System permit, primarily cooling tower blowdown along with low volume waste discharges into the reservoir near the main dam.The aquatic monitoring program conducted in 1992 continued. to support the Environmental Protection Plan for the Harris Plant and provided an assessment of the effects of plant operation on the various components of the aquatic environment. Water quality assessments in 1992 determined that nutrient concentrations, as measured by total phosphorus and total nitrogen, seemed to have stabilized but at a level greater than the concentrations observed when the reservoir was first created and prior to power plant operations. Algal blooms, although not uncommon in piedmont reservoirs, now occur at least several times each year. However, the blooms have not been of the undesirable, noxious blue-green algal types and have not resulted in any fish kills.The major ions increased in 1992 as compared with their concentrations in previous years. Such increases reflected the prolonged retention time of water in the reservoir and the infrequent discharge of water over the spillway. Seventy-eight percent of the 300 metal and metalloid samples analyzed in 1992 were less than their respective laboratory reporting limit concentrations. Biofouling by introduced nonnative organisms--the Asiatic clam and the aquatic plant hydrilla--did not affect Harris Plant operations. The distributions of both species continued to expand throughout much of the shallow-water zone. No Asiatic clams were collected in samples taken from the auxiliary intake canal, the intake structures, or the fire protection system. No zebra mussels were found in the main or the auxiliary reservoirs. During 1992 the fishery was dominated by largemouth bass and several species of sunfish. An increasing proportion of the largemouth bass fishery was represented by quality-length fish which presented the recreational fisherman and bass tournament participants with excellent sportfishing opportunities. VII uarouna Power & Ught Company Harris Nuclear Power Plant 1992 Environmental Monitoring Report HARRIS NUCLEAR POWER PLANT 1992 ANNUAL ENVIRONMENTAL MONITORING REPORT Reservoir Description The main body of Harris Lake has a surface area of 1680 ha; the auxiliary reservoir has a surface area of 130 ha (Appendix 1). The main reservoir has a maximum depth of 18 m, a mean depth of 5.29 m, a volume of 8.88 x 10' m 3 , a full-pool elevation of 67.1 m (220 ft)National Geodetic Vertical Datum (formerly called mean sea level by the U.S. Geological Survey), and an average residence time of 28 months. The reservoir began filling in December 1980, and full-pool elevation was reached in February 1983. The 64.5-km shoreline is mostly wooded, and the 183.89-km 2 drainage area is mostly rolling hills with land used primarily for forestry and agriculture. Historical Overview Harris Lake was constructed to supply cooling tower makeup and auxiliary reservoir makeup water to the 900-MW, single-unit Harris Nuclear Power Plant which began commercial operation in May 1987. In 1986 the bottom waters of the reservoir began receiving NPDES-permitted wastewater discharges near the main dam. In 1987 macronutrients (as estimated by total phosphorus and total nitrogen concentrations) and ions (as estimated by total chloride and total sulfate concentrations) increased above the previous years' concentrations in the reservoir, particularly at the monitoring station closest to the dam (CP&L 1990a). Concomitantly, an increase in algal biomass (as estimated by chlorophyll a concentrations) was also observed throughout much of the reservoir. In May 1989 an algal bloom was observed throughout the reservoir for the first time, and chlorophyll a concentrations were measured above the North Carolina water quality standard (40 p.g/liter) at each of the four monitoring stations. In 1990 chlorophyll a concentrations approached or exceeded the water quality standard on three separate occasions and in 1991 on two separate occasions. The increased nutrient loadings from all point and nonpoint sources accelerated the primary productivity of Harris Lake from low/moderate productivity to moderate/high productivity within the period 1986-1989. The nutrient and chlorophyll a concentrations between Environmental Services Section I Environmental Services Section 1 Harris Nuclear Power Plant 1992 Environmental Monitoring Report 1989 and 1991 have remained stable but were at greater concentrations than what they were when the reservoir was first created and prior to operation of the plant.The shift in productivity has also resulted in a greater volume of the hypolimnion being oxygen-depleted during the summer months, diurnal fluctuations in the dissolved oxygen concentration in the shallow-water zone during the summer months, and reduced. water clarity.In June 1991 a die-off of freshwater mussels occurred, primarily in the Buckhorn Creek and White Oak Creek arms. This die-off was the first reported incident of this type in Harris Lake, and low dissolved oxygen concentrations in the shallow-water zone may have caused the die-off.Another significant change to the reservoir's benthic invertebrate community since impoundment was the colonization of the reservoir by the Asiatic clam Corbiculafluminea during 1988-1989. This nonnative organism has the potential to block power plant pipes and tubes in raw water systems. Until 1990 no clams had been collected from the intake structures or the auxiliary reservoir. In 1990 one individual was collected in the main intake canal. Although densities remained at low levels during 1991 and the reservoirwide monitoring program has not shown a rapid population increase, the presence of shells along the shoreline in many areas has indicated that the clam has continued to spread throughout the reservoir. No incidences of biofouling within the Harris Plant have occurred from the clams and operations have not been affected.The fishery has been dominated by the sport fishes bluegill, pumpkinseed, largemouth bass, redear sunfish, black crappie, and by gizzard shad. Monitoring of fish populations through 1987 and a study of largemouth bass age and growth in 1985 documented slow growth rates for this species. However, during 1988 and 1989, the size distributions shifted towards larger-size bass. This shift was probably the result of the increased primary productivity, the availability of suitable-size forage fish due to the introduction of threadfm shad by the North Carolina Wildlife Resources Commission (NCWRC) in 1987, and an increased abundance of suitable-size gizzard shad. This shift towards intermediate-to large-size largemouth bass has presented anglers the opportunity for greater fishing success. No detrimental impacts on the fish community from plant operations have been observed since the Harris Plant became operational. The aquatic plant hydrilla Hydrilla verticillata was initially found in 1988 growing in the White Oak Creek arm of the reservoir. Within a two-year period, this nonnative macrophyte had displaced the native species and had become the dominant littoral plant species. Since 1990 2 Carolina Power & Light Company Harris Nuclear Power Plant 1992 Environmental Monitoring Report creeping water primrose Ludivigia uruguayensis has also increased its littoral zone coverage in the main reservoir. The auxiliary reservoir, however, has remained relatively free of aquatic vegetation since its impoundment. Despite these shifts in the structure of the aquatic macrophyte community, the community has not impacted Harris Plant operations. Objectives The primary objective of the nonradiological environmental monitoring program for 1992 was to continue to support the Environmental Protection Plan for the Harris Nuclear Power Plant.Secondary objectives were to provide an assessment of the effects of plant operations on the various components of the aquatic environment in Harris Lake, to document any natural changes or changes induced by sources other than the power plant, and to assess the impact of any introduced nonnative species. These objectives have also been addressed in previous reports (e.g., CP&L 1990a, 1990b, and 1991, 1992).The 1992 environmental program included monitoring the limnology (water quality and chemistry and phytoplankton [algae]); Asiatic clam, zebra mussel, and fish populations; and the distribution of aquatic vegetation (Appendices 2 and 3). Sampling methods in 1992 were similar to those used in previous years (Appendix 4), except the electrofishing sampling was conducted biannually (May and November) rather than quarterly. Supporting data summaries, statistical analyses (Appendix 5), and key environmental indicators were used to describe and interpret the environmental quality of the reservoir. These indicators were included when a significant change or abnormal event occurred, an important trend was observed, or the potential for any of these was present. Other data were included as key indicators when there was environmental, public, or regulatory interest.The accuracy and precision of laboratory analyses of water chemistry data were determined with analytical standards, spikes, and replicates (Appendix 6). In this report where concentrations were less than the laboratory reporting limit, the concentrations were assumed to be at one-half the reporting limit for the calculation of the mean.EnvionmetalServcesSectonI Environmental Services Section 3 Harris Nuclear Power Plant 1992 Environmental Monitoring Report Key Indicators of Environmental Quality During 1992 Limnology (Appendices 7-18)Reservoir Elevations Reservoir water surface elevations ranged from 218 to 221 ft (66.5-67.4 m) in- 1992 (Appendix 7). Water spillage occurred from mid-June to mid-July and from early November to the end of the year. There was no spillage from the reservoir between early July 1991 until mid-June 1992--a period of approximately 350 days.Temperature

• Harris Lake is a warm-water, monomictic reservoir.

[A monomictic reservoir is defined as a reservoir whose water temperature is not less than 4'C and whose waters circulate freely in the winter but thermally stratify during the summer.] During 1992 surface water minimum temperatures ranged from 7.20 to 9.2°C and maximum temperatures ranged from 29.6' to 31.6°C (Appendix 8). The waters at the dekeper stations (E2, H2, and P2) were stratified from April (except Station P2) through September and were freely circulating from January through March (except Station H2) and October through December (Appendix 9).Specific Conductance

• Specific conductance (an estimate of the concentration of the dissolved ions) ranged from 51 to 198 ý&S/cm throughout the water column during. 1992 (Appendix 8). Specific conductance increased with depth during the summer months as the reservoir became thermally stratified.

When the bottom waters became increasingly devoid of oxygen during stratification, conditions were favorable for chemical reduction to occur and subsequent dissolution of ions.Dissolved Oxygen* A clinograde oxygen curve was observed for all stations from May through September and during November (Appendices 8 and 10). [A clinograde oxygen curve is defined as an abrupt depletion and undersaturation of oxygen with a concomitant increase in depth.] As water 4 Carolina Power & Light Company Harris Nuclear Power Plant 1992 Environmental Monitoring Report temperature increased and a well-defined thermocline developed during the summer, dissolved oxygen concentrations in the hypolimnion (bottom waters) typically decreased to anoxic (where dissolved oxygen concentrations were < 1 mg/liter) conditions (Appendices 8 and 10).The depressed percent oxygen saturation levels observed in January 1991 (CP&L 1992) were not repeated in 1992. Surface water percent saturation levels remained above 65% in 1992 (CP&L unpublished data), except for slightly lower levels during the fall turnover in October when oxygen-depleted bottom waters circulated to the surface.Solids, Turbidity, and Water Clarity" During 1992 there was no consistent spatial trend among the surface waters for all indicators and measurements of the optical clarity of the water--solids (total, total dissolved, and total suspended), turbidity, and Secchi disk transparency depth data (Appendices 11-13). However, the annual mean turbidity value at Station S2 (the upper reservoir station) was significantly greater than the values from the middle and lower reservoir stations (Stations E2, H2, and P2)(Appendix 13). Conversely, the mean Secchi disk transparency depth value at Station S2 was significantly less than at the other stations. This relationship was expected due to the tributary inflow and subsequent sediment transport from White Oak Creek and the negative relationship between two variables.

• There were no significant spatial trends for solids, turbidity, and Secchi disk transparency depth data during the period 1987-1992 (Appendix 14). Secchi disk transparency depth data was not inversely related to the temporal trend of decreasing annual mean turbidity values from 1987 to 1992, except for the peak turbidity mean in 1989 which corresponded to a peak chlorophyll a mean (Appendix 15). There were no significant temporal differences among the solids data for the period 1987-1992.

Algal Biomass* Reservoirwide mean chlorophyll a concentrations (an algal pigment that is used as an approximate measure of algal biomass) during 1992 ranged from 3.8 to 44.4 jig/liter (Appendices 11 and 13). There were no significant spatial differences in mean chlorophyll a concentrations during 1992 or from 1987 to 1992 (Appendices 13 and 14). The annual mean Environmental Services Section 5 Harris Nuclear Power Plant 1992 Environmental Monitoring Report chlorophyll a concentration for 1992 was not significantly different than the annual means for the period 1987-1991, except for 1989 which had the greatest mean value for this period (Appendix 15).The mean chlorophyll a concentrations for January 1992 at Station H2 (40.2 [tg/liter) and for August 1992 at Station E2 (44.4 lag/liter) were greater than the North Carolina water quality standard of 40 [tg/liter (Appendices 11 and 16) which indicated the occurrences of algal blooms as defined by the NCDEM (1992). Occasional chlorophyll a concentrations greater than the water quality standard are not an uncommon occurrence in piedmont reservoirs and have occurred periodically in Harris Lake since 1989.When the mean chlorophyll a concentration at Station H2 was elevated in January, the total algal density was in the lower end (9969 units/ml) of the range of conditions defined as an algal bloom (i.e., total density > 10,000 units/ml). The diatom Melosira distans and the flagellated cryptophyte Chroomonas minuta constituted approximately 45% of the total algal density. Chroomonas minuta was the taxon in greatest abundance (26% of the total density)during the bloom in August at Station E2. However, the total algal density for this month (5110 units/ml) was only in the moderate range (5-10,000 units/ml). Nutrients* There were no clear spatial differences in mean total phosphorus concentrations during 1992 (Appendix 13). Mean concentrations remained approximately 1.5-1.8 times greater at Station E2 than at either Station H2 or P2 during the 1987-1992 period (Appendix 14). The annual mean concentration for 1992 was not significantly different from the mean for 1991 and was significantly less than the mean for 1990 (Appendix 15). The annual mean concentrations in Harris Lake seemed to have stabilized at a level greater than the concentrations observed prior to the operation of the plant.During 1992 mean total nitrogen concentrations in the surface waters at Station E2 were greater than the concentrations at all other stations (Appendix 13). This pattern, however, was not evident from the long-term analyses during the period 1987-1992 (Appendix 14).6 Carolina Power & Light Company Harris Nuclear Power Plant 1992 Environmental Monitoring Report The annual mean concentration for 1992 was significantly less than the concentrations in 1990 and 1991 and returned to the lower levels that were observed during 1987-1989 (Appendix 15).Ions" Annual mean calcium concentrations in 1992 were significantly greater than the mean concentrations measured since 1989 but were within the range (3.3-3.8 mg/liter) of means for the 1987-1989 period (Appendix 15).* Annual mean concentrations of magnesium, sodium, chloride, and sulfate in 1992 were significantly greater than mean concentrations of these ions measured for the 1987-1991 period and continued a general increasing trend each year (Appendix 15). This trend may be reflective of the increased retention time of the water in the reservoir and the infrequent discharge over the spillway during the 1990-1992 period (Appendix 7).There were no clear spatial trends in the sodium concentrations during 1992 (Appendix 13).However, concentrations were significantly greater at Station E2 compared to the concentrations at either Station H2 or P2 during the period 1987-1992 (Appendix 14).Trace Metals and Metalloids" Excluding mercury and copper, all metal and metalloid concentrations measured in 1992 were less than the respective North Carolina water quality standard or action level (Appendices 12 and 17).* All mercury concentrations, except the sample collected from the bottom waters at Station E2 during November (0.11 jig/liter) and from the surface waters at Station E2 during March (0.05 jig/liter), were below the laboratory detection level of 0.05 jig/liter (Appendices 12 and 17). The North Carolina water quality standard for mercury is 0.012 jIg/liter." All copper concentrations during 1992 were less than the North Carolina action level (7 gg/liter), except during January when the concentration in bottom waters at Station E2 was 7.5 ýig/liter (Appendices 12 and 17). The 1992 annual mean concentration was similar to the Environmental Services Sect-ion 7 Harris Nuclear Power Plant 1992 Environmental Monitoring Report values calculated for 1989 and 1991 and was less than the annual mean concentrations observed for the years 1987-1988 and 1990 (Appendix 15). There were no significant spatial differences during the period 1987-1992 (Appendix 14).The annual mean aluminum concentration measured at Station S2 during 1992 was significantly greater than at all other stations (Appendix 17). Elevated values during January (610 jig/liter) and March (1200 jig/liter) contributed to the elevated mean for this station (Appendix 12). There were no significant spatial differences in the concentrations in the surface waters for the period 1987-1992 and there was not a clear temporal trend during this period (Appendices 14 and 15).Chemical Constituents from the Bottom Waters at Station E2* There were no significant differences in measured chemical concentrations between the surface and bottom waters at Station E2 during 1992 (Appendix 13). Significant differences were unlikely due to the expected variability in the concentrations in the bottom waters between periods of stratification and of uniform mixing in the water column. Concentrations of most chemical constituents (i.e., total alkalinity, hardness, the solids, total phosphorus, total nitrogen, ammonia, total organic carbon, total calcium, and total magnesium) increased during stratification to a maximum concentration by September because of the movement of chemicals across the sediment-water interface under the reducing anoxic conditions found in the bottom waters during that time (Appendix 12). Sulfate concentrations decreased during the stratification period because the sulfate was reduced to hydrogen sulfide." There were no significant differences among years (1987-1992) for solids (total, dissolved, and suspended solids), turbidity, nutrients (total nitrogen, nitrate + nitrite-N, ammonia-N, and total phosphorus), and total organic carbon in the bottom water at Station E2 (Appendix 18).* There were significant increases in the concentrations of the major ions--such as magnesium, sodium, chloride, and sulfate--in the bottom waters of Harris Lake at Station E2 during the period 1987-1992 (Appendix 18). There was no clear trend for total alkalinity and hardness concentrations for the period 1987-1992. U Carlin O L..g.t Coman 8I Carolina Power & Light Company Harris Nuclear Power Plant 1992 Environmental Monitoring Report* Aluminum and copper concentrations for 1992 in the bottom waters at Station E2 remained relatively unchanged for the period 1987-1992 (Appendix 18).Benthic Invertebrates Freshwater Mussels* There was no die-off of freshwater mussels in 1992 as there was in June 1991 in Harris Lake.Asiatic Clam Surveys* No Asiatic clams Corbiculafluminea were collected in either of the two intake canals during April 1992; however, during October one specimen was collected near the intake structure at Station MI (Appendix 1). The estimated density at this location decreased from 43 clams/m 2 in 1991 to 14 clams/m 2 in 1992. No Asiatic clams were collected in the auxiliary reservoir intake canal, in the intake structures, or in the fire protection system during 1992.* Asiatic clam shells were qualitatively observed at many locations along the shoreline which indicated that the species has continued to spread throughout the reservoir. Zebra Mussel Surveys* Zebra mussels Dreissenapolymorpha, potentially serious biofouling organisms to power plant operations, were not found during special monitoring activities. Although the species has not yet been reported from North Carolina, it has the potential to colonize the state during the next few years.Fisheries (Appendices 19-35)Fish Community Structure* The species composition during 1992 (i.e., 17 species representing 7 families) was similar to that observed in previous years (Appendix 19), and, as in previous years, the fish community and sport fishery were dominated by bluegill, largemouth bass, redear sunfish, gizzard shad, and pumpkinseed (Appendices 20 and 21). Construction of beaver lodges at some stations EniomnalSie Seto Environmental Services Section 9 Harris Nuclear Power Plant 1992 Environmental Monitoring Report provided increased cover which concentrated fish and made them more susceptible to electrofishing. There were, however, no significant spatial differences in the mean catch rate for any of these dominant species during 1992 (Appendix 20)." Although no channel catfish were collected and the mean catch rate for black crappie was low during 1992 (Appendix 20), conversations with anglers indicated that these species were being caught in sufficient numbers to also be considered an important part of the sport fishery." The mean catch rate of total fish using electrofishing sampling has not changed significantly during the past ten years, except during 1989 when the catch rate was significantly greater at a rate of 309 fish/hour (Appendices 21 and 22). The mean catch rate of total fish during the period 1983-1992 was significantly greater at Area V than at all other areas (Appendix 22).The mean catch rates for bluegill have not changed significantly since 1988 (Appendices 21 and 22). During the past ten years, the mean catch rate at Area V was significantly greater than at all other areas (Appendix 22). The quality of the bluegill fishery was evaluated with a length-frequency index based on the concept of total lengths as a percentage of world record lengths (Gabelhouse 1984). The catch rates of stock- and quality-length fish have generally increased since 1985, while the catch rate of preferred-length fish has generally been constant at approximately 1-3 fish/hr since 1986 (Appendix 23).The mean catch rates for redear sunfish during 1990-1992 were significantly greater than the catch rates during all the other years (Appendices 21 and. 22). There were no significant spatial differences in the mean catch rates for the period 1983-1992. The quality of the redear sunfish fishery was similarly evaluated with the length-frequency index based on world record lengths. The catch rates of stock- and quality-length fish have generally shown a steady increase since 1983 and the greatest rates were measured during 1992 (Appendix 24).The catch rate for preferred-length fish has fluctuated between 1-6 fish/hr since 1984, while the catch rate for memorable-length fish peaked in 1990 (Appendix 24).'U Carolina Power & Light Company 10 Carolina Power & Light Company Harris Nuclear Power Plant 1992 Environmental Monitoring Report* The mean catch rate for pumpkinseed during 1992 was significantly less than the catch rate in 1989 (Appendices 21 and 22). There were no significant spatial differences in the mean catch rates for the period 1983-1992.

• The mean catch rate of black crappie during 1992 was significantly lower than the catch rate in 1989 but not significantly different from any other year (Appendices 21 and 22). Black crappie were collected at significantly higher rates at Areas S and V than the other three areas during the same time period (Appendix 22). A study conducted by the North Carolina Wildlife Resources Commission (NCWRC) during 1992 concluded that the black crappie population in Harris Lake experienced "good" growth rates and size structure among the various age classes of fish (Mr. Wayne Jones, NCWRC, pers. comm.)." As in 1991, greater numbers of intermediate-to large-size sport fishes were collected by electrofishing sampling during 1992 than in previous years based upon a comparison of the length-frequency distributions (Appendices 25-28). The length-frequency histograms for redear sunfish indicated adequate recruitment and size distributions during 1992 (Appendix 26). Recruitment for bluegill, pumpkinseed, and black crappie was as low or lower than observed in previous years as indicated by few fish < 60 mm (Appendices 26-28)." The length-frequency histograms for gizzard shad and brown bullhead in 1992 indicated a greater proportion of larger fish was collected than what would have been expected (Appendices 29 and 30). This may have occurred because electrofishing sampling can be biased against the collection of small (i.e., < 65 mm) fish (Reynolds 1983). The small individuals of these two species are usually found in dense vegetation (brown bullhead) or in open deep water (gizzard shad)--areas not usually sampled efficiently with the boat electrofisher.

Larmemouth Bass Population Structure* The mean catch rate of largemouth bass during 1992 was not significantly different from catch rates during 1985-1988 and 1991 but was significantly less than the catch rates during the years 1983-1984 and 1989 (Appendices 21 and 22). The mean catch rate at Area S was significantly less than the catch rates at all other areas during the period 1983-1992 Environmental Services Section 11 Harris Nuclear Power Plant 1992 Environmental Monitoring Report (Appendix 22). A study conducted by the NCWRC during 1992 concluded that the catch rate at Harris Lake (3.9 fish/100 m of shoreline) was slightly greater than the catch rates for Falls of the Neuse Reservoir and Lake Gaston (2.4 and '.5 fish/100 m of shoreline, respectively) (Mr. Wayne Jones, NCWRC, pers. comm.)." The length-frequency histogram indicated adequate recruitment and size distribution during 1992 (Appendix 31).* The quality of the largemouth bass fishery was evaluated with the length-frequency index based on world record lengths as previously applied to the bluegill and redear sunfish fishery.The catch rate of stock-length fish has generally decreased since 1984 to a level of approximately 5-8 fish/hr (Appendix 32). Quality-length fish peaked in 1988 at a rate of 9 fish/hr and have gradually increased during the past two years as have preferred-length fish.Prior to 1991, no memorable-length fish had been collected in Harris Lake during the May and November electrofishing sampling. In 1992 the memorable-length fish catch rate was approximately 1 fish/hr." The quality of the largemouth bass fishery was further assessed with two correlated indicies-- Proportional stock Density (PSD) and Relative Stock Density (RSD). The PSD is a measure of the proportion of quality-size fish (fish > 300 mm) in the population (all fish collected> 200 mm), and the RSD is the propm -..n::on of fish of any designated size group in a population (Anderson and Gutreuter 1983). For example, an RSD-380 (i.e., preferred-length) is the proportion of the population that was > 380 mm." The PSD of largemouth bass in 1992 continued to be in the optimal range (Appendix 33), indicating that the population contained many quality-length fish and was balanced for a moderate density objective (Gabelhouse 1984). A moderate density objective is defined as where largemouth bass are one of several species of equal importance in a balanced community (Gabelhouse 1984). This was opposite the situation which occurred during the period 1983-1987, when the PSD was below the optimal level indicating that the population contained few quality-size fish.-Il uariPoe & Lig... coman 1Ai Carolina Power & Ught company Harris Nuclear Power Plant 1992 Environmental Monitoring Report" The RSD-380 of largemouth bass also showed continued improvement during 1992 (Appendix 33). The RSD-380 since 1989 has also remained in the optimal range for a moderate density objective (Gabelhouse 1984). This proportion of the total population was the greatest since impoundment, further supporting the observations that the largemouth bass sport fishery has continued to improve." During March 1992, 126 anglers participated in a largemouth bass tournament held at Harris Lake. The tournament rules allowed each team to "weigh-in" ten fish. Two of the fish were allowed to be between 12 and 14 inches (305-356 mm) and the eight other fish were required to be >_ 14 inches. Two hundred sixteen fish were "weighed-in" during the tournament. This resulted in the greatest tournament weigh-in catch rate, 0.20 fish/angler-hour, since 1987 (Appendix 34). [Note: "tournament weigh-in catch rate" is not synonymous with the term"catch rate" used elsewhere in this report. This term is used by CP&L fishery biologists to conveniently measure the relative success of largemouth'bass tournaments.]" The length-frequency distribution of "weighed-in" fish during the tournament indicated that a greater number of fish >_ 356 mm were caught in 1992 as compared with the distributions in either 1987 or 1990 (Appendix 35). The 1992 length-frequency distribution was similar to that from the 1991 tournament. Aquatic Vegetation (Appendix 36)" During 1992, hydrilla Hydrilla verticillata continued to be the dominant species of aquatic vegetation in Harris Lake. This nonnative, submersed plant grew in homogeneous stands throughout the littoral zone (< 3 m deep) of the reservoir except for the Buckhom Creek arm (Appendix 36). A previously observed small patch in that arm was not present in 1992.Also, the amount of hydrilla in a cove near the dam greatly decreased in surface area from that of 1991. The areal coverage of hydrilla in Harris Lake in 1992 was approximately 430 ha, an increase of only 5 ha since 1991. This species had no impact to the Harris Plant's operation. Environmental Services Section 13 Harris Nuclear Power Plant 1992 Environmental Monitoring Report" Only one species of submersed vegetation, naiad Najas minor, was observed growing in the auxiliary reservoir. This occurred in the shallow areas of the headwaters near U.S.Highway 1. One small patch of water shield Brasenia schreberi occurred near the auxiliary reservoir dam." Emergent vegetation grew along the shoreline of both the main and the auxiliary reservoirs. The dominant species were cat-tail Typha latifolia, rush Juncus effusus, bulrush Scirpus cyperinus, and the emergent form of creeping water primrose Ludwigia uruguayensis (which did not occur at the auxiliary reservoir). The littoral zone of the Buckhorn Creek arm supported three submersed native species; spike-rush Eleocharis baldwinii, naiad, and musk-grass Chara sp. Coverage varied from sparse to dense and most vegetation occurred in protected coves.Floating-leaf vegetation throughout Harris Lake was dominated by creeping water primrose and lotus Nelumbo lutea. Creeping water primrose grew along the shoreline of all major arms of the lake, primarily in the coves. Lotus was restricted to several stands in the headwater area of the White Oak Creek arm. Water shield and water-lily Nymphaea odorata also grew in small to moderate areas throughout the reservoir's littoral zone.Conclusions The primary objective of the 1992 nonradiological environmental monitoring program was to continue to support the Environmental Protection Plan for the Harris Nuclear Power Plant.Secondary objectives were to provide an assessment of the effects of plant operations on the various components of the aquatic environment, to document any natural changes or changes induced by sources other than the power plant, and to assess the impact of any introduced nonnative species.The environmental monitoring programs that were conducted prior to commercial operation of the Harris Plant determined that Harris Lake was in many ways a typical southeastern, moderately productive reservoir. However, after the Harris Plant began discharging cooling tower blowdown and other NPDES-permitted wastewater discharges into the reservoir, the reservoir became more biologically productive. Environmental characteristics of a typical 14 Carolin Power & igh opn 14 Carolina Power & Light Company Harris Nuclear Power Plant 1992 Environmental Monitoring Report Harris Nuclear Power Plant 1992 Environmental Monitoring Report southeastern, biologically productive reservoir include the presence of oxygen-deficient subsurface waters, elevated nutrient and algal concentrations, reduced water clarity, an abundance of rooted shallow-water aquatic plants, and a productive sport fishery--all characteristics of Harris Lake.*Water quality assessments determined that nutrients, as measured by total phosphorus and total nitrogen, did not increase during 1992 and seemed to have stabilized but at a level greater than the concentrations observed prior to the operation of the Harris Plant. Algal blooms, although not uncommon in piedmont reservoirs, now occur several times per year in Harris Lake.The blooms, however, have not been composed of the noxious blue-green algal types and have not resulted in any fish kills.The major ions (i.e., calcium, magnesium, sodium, chloride, and sulfate) continued to increase in 1992 as compared with concentrations in previous years. Such increases may reflect the reservoir's prolonged retention time and the infrequent spillage of water from the reservoir. Seventy-eight percent of the 300 metal and metalloid concentrations analyzed in 1992 were less than the laboratory reporting limit.Biofouling by the Asiatic clam and the aquatic plant hydrilla did not impact Harris Plant operations. Each of these species continued to slowly expand its distribution throughout much of the littoral zone of the reservoir. No clams were collected in the auxiliary intake canal, in the intake structures, or in the fire protection system. The zebra mussel, another potentially biofouling organism, was not found in the main or the auxiliary reservoirs. The recreational and sport fishery, as in previous years, was dominated by largemouth bass and several species of sunfish. During the past several years, an increasing proportion of the largemouth bass fishery has been represented by quality- or better-length fish which have provided the recreational fishermen with a greater opportunity for fishing success.References Anderson, R. 0., and S.

Harris Lake environmental monitoring program changes from 1991 to 1992.Program Change Limnology Water quality, water chemistry Increased sampling frequency from alternate months to (nutrients), and plankton monthly to model nutrient and chlorophyll a relationships and the eutrophication of Harris Lake.Benthic invertebrates Asiatic clam surveys Discontinued littoral zone survey because reservoir monitoring was not a Nuclear Regulatory Commission requirement (Generic Letter 89-13).Zebra mussel surveys Added to monitoring program as a Special Study to document possible introduction of the species into the reservoir. Fisheries Fish community structure Reduced sampling frequency from quarterly to biannually (spring and fall) to adequately monitor the general status of the fishery.Aquatic vegetation Survey Discontinued summer survey because hydrilla was well established and one fall survey was sufficient for documenting its distribution. Environmental Services Section A-3 Environmental Services Section A-3 Harris Nuclear Power Plant 1992 Environmental Monitoring Report Appendix 4. Field sampling and laboratory methods followed in the 1992 Harris Lake environmental monitoring program.Program Method Limnology Water quality Water chemistry Plankton Phytoplankton Chlorophyll a Benthic invertebrates Asiatic clam surveys Temperature, dissolved oxygen, pH, and conductivity were measured with a calibrated Martek Mark XV instrument and YSIO dissolved oxygen meter. Measurements were taken from surface to bottom at 1-m intervals. Water clarity was measured with a Secchi disk.Surface and bottom samples were collected with a nonmetallic Van Dorn sampler, transferred to appropriate containers, transported to the laboratory on ice, and analyzed according to USEPA (1979) and APHA (1986).Equal amounts of water from the surface, the Secchi depth, and twice the Secchi depth were obtained with a Van Dorn sampler and mixed in a plastic container. A 250-ml subsample was taken and preserved with 5 ml of "M3" fixative. Subsamples were identified and enumerated in the laboratory. Three 1000-ml samples were collected from the surface, the Secchi depth, and twice the Secchi depth with a Van Dorn sampler, placed in dark bottles, and transported to the laboratory on ice. At the laboratory, two 250-mi subsamples were analyzed according to Strickland and Parsons (1972) and APHA (1986).At Stations V3, Z1, MI, and AI, three replicate samples were collected with a petite Ponar at the 2-m depth. In the emergency service water and cooling tower makeup intake structures, seven samples were collected with a petite Ponar.Samples were preserved with 5% formalin and returned to the laboratory where they were elutriated through 1000-, 500-, and 300-ji mesh sieves. Asiatic clams were counted, measured, and preserved. A- Carlin.Poer..LghtComa.

This sampler, the dock at the Holleman's boat ramp, or the water quality station marker buoys were visually inspected for the presence of mussels during routine water quality or Asiatic clam survey monitoring. Fifteen-minute samples were collected at each station using a Smith-Root equipped Wisconsin-design electrofishing boat with pulsed DC current. Fish were weighed, measured, and released.After largemouth bass tournament officials had recorded their necessary measurements, fish were weighed, measured, tagged, and released.Portions of the shoreline and/or littoral zone of the lake and auxiliary reservoir were systematically surveyed by boat for the presence of aquatic vegetation. The location and extent of observed species were recorded on maps and in field notes.Estimation of areal coverage of hydrilla was made by measuring the maximum depth of its growth at 49 transects throughout the lake and applying these data to topographic maps.Environmental Services Section A-5 Environmental Services Section A-5 Harris Nuclear Power Plant 1992 Environmental Monitoring Report Appendix 5.

Fisher's protected least significant difference test was applied to determine where difference in means occurred if the overall F test from the analysis of variance (ANOVA) indicated that the main effect was significant. iChlorophyll a ANOVA models were structured using the mean station-by-month concentration based on three paired replicate samples.TFisheries data were transformed using the loge (number of fish/hour + 1) transformation. Because of the change in the sampling regime between 1992 and previous years (i.e., from quarterly to biannual [May and November] sampling), the ANOVA models were fitted with only the biannual data across all years.A-6 Carolina Power & Light Company A-6 Carolina Power & Light Company Harris Nuclear Power Plant 1992 Environmental Monitoring Report Appendix 6.
