Division of Water Quality Progress Energy Progress Energy Tillery Tailwaters Aquatic Monitoring Plan 1.0 Introduction Progress Energy was issued a 401 Water Quality Certification (WQC) by the N.C. Division of Water Quality (NCDWQ) on February 11, 2008, for the Yadkin -Pee Dee Hydroelectric Project No. 2206 (NCDWQ 2008). Approval of the WQC is required as part of the federal relicensing of the hydroelectric project by the Federal Energy Regulatory Commission, pursuant to the National Environmental Policy Act and the Clean Water Act. Operation conditions of the 401 WQC will be incorporated into the new license expected to be issued by the FERC during 2008 to Progress Energy. Section 7 of the WQC requires that Progress Energy conduct aquatic life monitoring in the Pee Dee River below the Tillery Hydroelectric Plant to document the condition of the aquatic community. A five mile reach of the river from Tillery Dam to the confluence of the Rocky River will be monitored to note improvements in aquatic community following changes to the dissolved oxygen (DO) and instream flow regime during the next license term. Baseline data ( "pre -new license period conditions ") will be collected under the existing conditions and prior to these changes under the power plant operating regime for the next license term. The baseline data will be then compared to the environmental conditions in the next license term ( "post -new license period conditions "). Improvements of the aquatic community can then be assessed and a determination made as to whether the power plant DO and flow improvements have improved the aquatic community or whether other environmental factors (e.g., nonnative species competition and predation, basinwide sedimentation or other water quality issues) are affecting the community. The purpose of this document is to provide a detailed study plan that will be used for aquatic life monitoring for the next license term. The aquatic life monitoring will be focused on the benthic invertebrate and fish communities, which provide a relative indication of environmental health in the identified river reach. This study plan will require review and approval by the N.C. Division of Water Quality and the FERC prior to implementation. This study plan will be used to guide the biological assessments for the period extending from the date of license issuance to 2020. Changes may be necessary to the study plan based on best available information in the future or changes in sampling methodology with technological or science -based knowledge advancements. Any changes to the study plan methodology will be made with joint agreement between Progress Energy and NCDWQ with subsequent approval by NCDWQ and FERC prior to implementation of such changes. Progress Energy submitted a draft study plan to the NCDWQ on May 20, 2008, for review and comment (Appendix 1). A copy was also sent to the N.C. Wildlife Resources Commission and the N.C. Division of Water Resources for review. Comments were received on the draft study plan from these agencies (Appendix 1) and incorporated into this final study plan. FINAL 1 REV 1. (06/12/08) Progress Energy Tillery Tailwaters Aquatic Monitoring Plan 2.0 Monitoring Locations The aquatic life monitoring will be conducted at two sites (Sites TZ1 and TZ2) located in the 5- mile reach of the Pee Dee River below the Tillery Hydroelectric Plant (Figure 1). The length of each monitoring site will be approximately 366 in (1200 feet) in length. Site TZ1 is located approximately 1.5 miles below the Tillery Plant, immediately downstream of N.C. Highway 731 Bridge (Figure 1). This upstream site, Site TZ1, is a simple shoal and shallow run with bedrock outcrops and boulders, cobble intermixed with gravel and sand, and cobble and gravel bars present with some sand and silt deposition. Woody debris and rooted aquatic vegetation (Podosteinuin sp., Potainogeton sp., and filamentous algae) are prevalent at this site. This site includes the area where transects (i.e., Reach 3, Subreach 3, T7 and T8, see Progress Energy 2004) were placed for the instream flow study. The downstream site, Site TZ2, is also shoal and shallow run habitat located approximately 4.5 miles downstream of the Tillery Plant and just above the Rocky River confluence (Figure 1). The substrate consists of bedrock outcrops and boulders, cobble intermixed with gravel and sand, and cobble / gravel/sand bars present. Sand and some silt deposition occur along channel margins. Woody debris and rooted aquatic vegetation (Podostelnuin sp. and filamentous algae) are prevalent at this site. Both monitoring sites are similar in aquatic habitat characteristics, including channel width (170- 200 m) and depth, instream cover, and substrate types. Prehistoric fish weirs are also present at both sites. In addition, both monitoring sites have reasonable, safe access for sampling. Progress Energy and NCDWQ staff will conduct a joint field site visit to select the specified sampling stations within these monitoring sites prior to the first sampling event. The NCDWQ will make the final approval of monitoring stations prior to initial field sampling activities. 3.0 Monitoring Methods 3.1 Monitoring Frequency Aquatic life monitoring will be conducted for the benthic macroinvertebrate and fish communities at Sites TZ1 and TZ2 in the Pee Dee River below the Tillery Hydroelectric Plant (Figure 1). Sampling will be initially be conducted during the summer of 2008 to establish baseline conditions ( "pre -new license period" or existing environmental conditions) prior to modifications to flow and dissolved oxygen levels in the river following issuance of the new FERC operating license. The baseline data can be used to determine changes in the benthic macroinvertebrate and fish communities during the next license term per aquatic life monitoring conditions outlined in the NCDWQ 401 WQC ( NCDWQ 2008). Sampling will then be conducted every three years (i.e., 2011, 2014, 2017, and 2020, "post -new license period ") until the biological criteria have been meet or 2020, whichever comes first. FINAL 2 REV 1. (06/12/08) Progress Energy Tillery Tailwaters Aquatic Monitoring Plan If the biological criteria have not been met by 2020, NCDWQ and Progress Energy will review the monitoring data to determine if other environmental conditions beyond the control of Progress Energy (e.g., extreme drought conditions, large flooding events, etc.) are influencing the aquatic community in the Pee Dee River reach. If not, NCDWQ and Progress Energy will re- evaluate management options to improve the aquatic community, including those within and outside the control of Progress Energy. Monitoring will be conducted during the summer of each specified monitoring year (July through August). The fish and benthic invertebrate sampling events will be scheduled within a three week window for all monitoring events in order to reduce temporal variability in sampling the aquatic community. A reasonable effort will be made to sample within this three week window. However, environmental circumstances beyond the control of Progress Energy may delay sampling beyond a three week window (e.g., heavy rainfall and flooding events). Progress Energy will consult with the NCDWQ and obtain approval prior to deviating from this three week window for sampling. 3.2 Benthic Macroinvertebrate Community Monitoring Benthic macroinvertebrate monitoring will be conducted using the NCDWQ Standard Qualitative Method (SQM) for benthic macroinvertebrates (NCDWQ 2006a) or the most up -to- date version of this method, if there are any revisions made by NCDWQ in future years. If the SQM is revised by the NCDWQ, Progress Energy will consult with the NCDWQ to ensure the data collected under the revised SQM will be comparable to previously collected data. Ten qualitative samples were collected from each sampling station for the bioassessment and rating of the general environmental quality of the river based upon benthic community structure attributes (e.g., total number of species, number of mayfly, stonefly and caddisfly taxa, and species tolerance values): Habitat Microhabitat Sample Method Number of Samples Type of Sample Coarse -mesh (500 -1000 µm) High current with Riffles Kick net 2 Single, disturbance structure Low current with Banks Dip net 3 Composite, structure disturbance Leaves Leaf packs Wash bucket I Composite, wash Fine -mesh (300 µm) Aufwuchs Rock and logs U.S. Standard Sieve 2 Composite, wash Size No. 50 FINAL 3 REV 1. (06/12/08) Progress Energy Tillery Tailwaters Aquatic Monitoring Plan Habitat Microhabitat Sample Method Number of Samples Type of Sample Sand Sand U.S. Standard Sieve 1 Composite (3), Size No. 50 disturbance Visual Collections Large rock and logs (10 -15 minutes) 1 Composite Samples will be sorted in the field using a U.S. Standard Sieve Size No. 50, a white enamel pan, and a winnowing technique. All organisms will be preserved in 95% denatured- ethanol and returned to the laboratory for identification to the lowest practical level using standard taxonomic references and enumeration. A voucher and reference collection will be established for each sample location to validate taxonomic identification. A numerical abundance for each taxon will be tabulated as Rare = 1 (1 -2 specimens), Common = 3 (3 -9 specimens), and Abundant = 10 (specimens). Pollution tolerance values (TV) for each taxon will be based on criteria in NCDWQ (2006a) or if the taxon has not been assigned a value, a value will be assigned based on conversations with personnel with the NCDWQ. Specific instances for assigning tolerance values are given below: • If the specific species does not have a TV, but there was a TV for the genus level, then the genus level TV was used. • If there is no new score available for the taxon, the old score will be used. • If there is no new score for a specific species or for the genus level, then the old genus level score will be used. • If there is no TV for the genus level, the species will not be included in the calculation. • When there is a scoring issue that could not be resolved by the criteria above, personal communication with the NCDWQ will be used to assign a TV. • If there is insufficient knowledge for a particular taxon, then no TV will be assigned and the taxon will not used in calculation of the overall index value. FINAL 4 REV 1. (06/12/08) Progress Energy Tillery Tailwaters Aquatic Monitoring Plan The Biotic Index (BI) for each sample will be calculated as: S BI = Y, ni . ai/N i= 1 where N is the total number of individuals in the sample, ni is the number of individuals in the ith species (taxon), ai is the pollution tolerance value for the ith species, and S is the number of species. The BI Value and the EPT Value (the number of Ephemeroptera [mayflies], Plecoptera [stoneflies], and Trichoptera [caddisflies] taxa) will be assigned a score based on the expected scores from the Piedmont Ecoregion as developed by the NCDWQ ( NCDWQ 2006a). No seasonal correction values will need to be applied to these data as the sampling will occur during the summer months. The two indices (matrices) for each sample will be averaged (with scores rounded upward) to produce the final numerical ranking. The NCDWQ specified numerical rounding approach will be applied to the resulting BI and EPT if the scores differ by exactly one bioclassification. Bioclassifications for each sample (location) will be based on the final ranking: Excellent = 5, Good = 4, Good -Fair = 3, Fair = 2, and Poor = 1. A bioclassification ranking of at least "Good- Fair" will be used to establish successful response of the aquatic community to flow and DO improvements by the power plant during the next license term. 3.3 Fish Community Monitoring Fish community monitoring will follow methods established for the relicensing shallow water study conducted during 2004 (Progress Energy 2006b) and as outlined below. A standardized approach will be used to sample the shallow water fish community at each site. Sampling gear types used will include a Smith -Root 5.0 GPP pram electrofisher (or equivalent model), a Smith -Root Model 15 backpack electrofisher (or equivalent model), and a 20 -foot flat seine (6.1 -m x 1.8 -m with 0.32 cm mesh). The pram electrofisher will be used to sample the channel by making three passes through the site (i.e., each river bank and mid channel, wadeable portions). The side margins of the channel, including any backwater areas, will be sampled with the backpack electrofisher for 15- minute intervals. Twelve seine hauls (i.e., one haul per 100 feet of transect length) will be made at sand, gravel, or cobble bars or riffles at each transect with all collected samples combined into one common sample. For electrofishing sampling, pulsed DC current will be utilized for sampling with voltage adjusted to produce 3 -4 amps in the sampling field, depending upon the water conductivity. Backpack electrofishing will be conducted for 15- minute intervals along each channel margin and any associated backwater FINAL 5 REV 1. (06/12/08) Progress Energy Tillery Tailwaters Aquatic Monitoring Plan areas. Electrofishing will be conducted in either an upstream or downstream fashion at each transect. Riffle areas will be sampled intensively with the pram electrofisher by disturbing the substrate and holding dip nets on the downstream end of the riffle while the electrofishing is performed The total time will recorded for backpack and pram electrofishing, and the catches will be adjusted to number and weight of fish per hour. All fish, regardless of sampling methodology, will be identified to the lowest practicable taxa level. Fish will be measured for total length to the nearest millimeter and weighed to the nearest gram. Fish that cannot be accurately identified in the field or large numbers of small individuals will be preserved with 10% buffered formalin solution and transported to the laboratory for identification and body measurements. All other collected fish will be released alive at the sampling site. Fish will be retained for voucher purposes, as necessary, in Progress Energy's fish reference collection. All electrofishing and seine samples will be combined at each site to yield the total number of fish collected per sample site. In addition, the summary catch - per -unit effort data will be calculated for both electrofishers and seine hauls. Dominant species within the fish community will be defined as those species or taxa comprising >_ 5% of the total fish abundance at each transect. The fish data will be assigned tolerance and trophic feeding guild classifications based on designations used by the NCDWQ for its North Carolina Index of Biotic Integrity ( NCIBI) methodology ( NCDWQ 2006b). The NCIBI is a modification of the Index of Biotic Integrity originally formulated by Karr (1981) to measure the health and structure of stream fish communities. The NCIBI fish community metrics or attributes will also be applied to the data to gain insight into the fish community structure at each sampled site. Three other attributes —the number of minnows (Cyprinidae), the number of North American catfish species, and the number and percentage of nonnative species —will also be included in this assessment. The percentage of green sunfish attribute was also included because previous sampling has indicated the presence of this species. The presence of green sunfish is a general indicator of degraded environmental conditions. The number of fish with disease, fin erosion, lesions, or tumors will also be used in the fish community monitoring to note any environmental stressors contributing to these conditions. The number of minnow species was added to evaluate the presence of this family (Cyprinidae) at the sampled transects. Young -of -year fish will be included in the calculation of all of the fish community attributes listed below. The significance of each fish community metric or attribute is given below, as defined in NCDWQ (2006b): 1. Number of taxa or species richness: The total number of species supported by a stream of a given size within a given region generally decreases with environmental degradation. In addition, some streams with larger watersheds or drainage areas can be expected to support more FINAL 6 REV 1. (06/12/08) Progress Energy Tillery Tailwaters Aquatic Monitoring Plan species than stream with smaller watersheds. In other instances, the number of species and watershed size are not correlated. 2. Number of individuals: The total number of fish supported by a stream of a given size in a given region decreases with environmental degradation. However, in some instances, nutrient enrichment or degradation may actually increase the number of fish supported by a stream. 3. Number of darter species (Etheosotoma and Percina species): Darters are sensitive to environmental degradation particularly as a result of their specific reproductive and habitat requirements. Darter habitats (e.g., riffle habitat) are degraded as a result of channelization, siltation, reduced oxygen levels, and fluctuating water levels. The collection of fewer than expected number of species of darters can indicate some degree of habitat degradation. 4. Number of minnow species: Many species of minnows are intolerant of habitat and chemical degradation and, because some of the species have life spans of up to six years, provide a multi -year integrated perspective. Because of their predominantly specialized insectivorous feeding habits, they also reflect the condition of the benthic community which may be harmed by sedimentation, sediment contamination, or varying water levels. Minnow species also typically inhabit shallow water habitats such as stream channel margins which can be affected by fluctuating water levels in regulated streams (Bain and Travnichek 1996). 5. Number of North American catfish species: The number of North American catfish species can provide insight into general environmental conditions present in a stream. Many North American catfishes are omnivorous feeding generalists tolerant of a wide range of environmental conditions. Conversely, madtom species inhabit shallow water areas and are insectivorous in feeding habits and generally reflect favorable stream environmental conditions. This attribute is not used in the NCIBI but used in this assessment to characterize the entire fish community present in the Pee Dee River. 6. Number of sucker species (includes all species within Catostomidae Family): Many suckers (especially Moxostoina or Scartoinyzon species) are intolerant of habitat and chemical degradation, and because they are long- lived, provide a multiyear integrated perspective. They also reflect the condition of the benthic community which may be affected by sedimentation, sediment contamination, or flow fluctuations. 7. Number of sunfish species (includes Lepomis, Enneacanthus, Micropterus, and Pomoxis species): Sunfish species are particularly responsive to habitat degradation such as the filling in of pools with sediment and loss of stream cover (e.g., woody debris). Conversely, most sunfish species (e.g., bluegill, redbreast sunfish, and largemouth bass) are habitat and feeding generalists and show less sensitivity to flow fluctuations that other species who are more specialized in feeding or inhabit channel margin habitat (Bain and Travnichek 1996). FINAL 7 REV 1. (06/12/08) Progress Energy Tillery Tailwaters Aquatic Monitoring Plan 8. Number of intolerant species: Intolerant species are those specialized habitat and feeding species most affected by environmental perturbations, and therefore should disappear, at least as viable populations by the time a stream is rated as "Fair ". Intolerant species includes some species with a very restricted zoogeographic distribution or considered rare, threatened, or endangered. Of the approximately 219 species of freshwater fish in North Carolina waters, 54 species are considered intolerant. 9. Percent tolerant individuals: Tolerant species are those which are often present in a stream in low or moderate numbers but as the stream degrades, they can become dominant (generally greater than 25 -35% of the fish community). Of the approximately 219 species of freshwater fish found in North Carolina, 22 species are tolerant. The metric is calculated by the total number of individuals of tolerant species divided by the total number of collected fish. 10. Percent omnivores and herbivores: Omnivorous feeding species generally indicate degraded environmental conditions, particularly the benthic invertebrate community. Additionally, large numbers of herbivores can indicate canopy or riparian removal or modifications and /or nutrient enrichment with subsequent increased growth of attached algae and periphyton. 11. Percent piscivores: Piscivorous feeding species represent the top of the food chain within the aquatic community and their presence usually indicates a healthy, functioning food chain. However, a very large percentage of piscivorous species or the complete absence of predators may indicate environmental perturbations or some other influencing factor. 12. Percent insectivores: Insectivorous feeding species, particularly those that specialize on the benthic invertebrate community (i.e., many minnow, sucker, and darter taxa) generally reflect a healthy river ecosystem. The presence of a large percentage of generalist insectivorous feeding species, particularly those that can feed on a variety of aquatic and terrestrial invertebrates, (e.g., redbreast sunfish and bluegill) can indicate degraded environmental conditions and nutrient enrichment. 13. Percent green sunfish: The percentage of green sunfish, a tolerant species, typically increases with degraded environmental conditions (generally > 5% of total fish collected would be considered unbalanced) (Karr et. al 1986). This attribute is not included in the NCIBI but used in this assessment to aid in characterization of the fish community and environmental conditions. 14. Percentage of species with multiple age groups: This metric or attribute provides an indication of reproductive success and survivability of year classes through time. It also provides an indirect indicator of suitable habitat for reproduction and rearing of young. At least three individuals per species must have been collected to determine the presence of multiple age FINAL 8 REV 1. (06/12/08) Progress Energy Tillery Tailwaters Aquatic Monitoring Plan groups within the population. In some instances, professional judgment may also be used to determine reproductive success of a particular species. 15. Number of nonnative species and percentage of nonnative species to native species: Nonnative species are currently prevalent in the Pee Dee River below the Tillery Hydroeletric Plant, especially smallmouth buffalo. The presence of nonnative species can negatively affect native species abundance and population response due to predation, competition, or both factors interacting together. This attribute is not included in the NCIBI but included in this fish community monitoring because of the large presence of nonnative species in the Pee Dee River. 16. The percentage of fish with disease, fin erosion, lesions, or tumors: This attribute provides insight into existing environmental conditions or stressors that may be contributing to the overall health of each fish species and the fish community as a whole. Other attributes may be identified in the future that can be used to further describe the fish community. Inclusion of these attributes will be based on the known technical knowledge existing at the time regarding fish community structure and best professional judgment. Progress Energy will use any other identified attributes that will best describe the fish community structure and note those in the written reports submitted to NCDWQ and FERC. Conversely, the listed attributes may be modified or deleted if they do not provide any meaningful insight into fish community dynamics through time. Those changes will also be noted in the report. The structure of the fish community at each site will be described based upon these attributes and a comparison will be made from between the "pre -new license period" and the "post -new license period ". Changes in the fish community abundance, species richness or composition, and structure will be evaluated over time. The fish community data cannot be quantitatively scored with the NCIBI (i.e., numeric score with corresponding community health rating). The scoring methodology has not been applied to large river systems, such as the Pee Dee River, with the specific array of sampling gear types used in this study ( NCDWQ 2006b). Neither reference conditions nor accepted sampling methodology have been established to apply the NCIBI in large river systems. Therefore, there will be no strict success criteria for judging the health of the fish community under this monitoring program. If the NCDWQ develops standardized success biocriteria for fish in future years, which are similar to the benthic macroinvertebrate biocriteria, then NCDWQ may request Progress Energy to include those criteria in future years for the aquatic life monitoring program under the 401 WQC. Progress Energy will provide review and input into any developed fish biocriteria prior to implementation into this monitoring plan. The FERC will approve the final included fish biocriteria. FINAL 9 REV 1. (06/12/08) Progress Energy 4.0 Other Environmental Measurements Tillery Tailwaters Aquatic Monitoring Plan At each sampling location, water temperature, dissolved oxygen, pH, conductivity, and turbidity will be measured with a laboratory- and field- calibrated YSI® multi - parameter instrument or a comparable instrument. Sample locations will be recorded with a GPS unit with sub -meter accuracy. Digital photographs were also taken of each sampling site. Flow data will be obtained from the Tillery Plant and /or the USGS gage which will be installed at the N.C. Highway 731 Bridge as part of instream flow compliance monitoring during the next license term. During each year of aquatic monitoring sampling, a continuous temperature and dissolved oxygen sonde will be deployed at Site TZ2 to note these parameter conditions during the period of summertime reservoir stratification (May through November). These parameters and the existing conditions will aid in evaluating the overall health and response of the aquatic community at this site. At Site TZ1, a continuous monitoring sonde will be permanently installed at the USGS gaging station to determine compliance for dissolved oxygen water quality standards in the next license term. Data from this sonde will also be used to evaluate the environmental conditions present at Site TZ1. 5.0 Reporting Requirements A written report shall be prepared and submitted to the NCDWQ and FERC by no later than March 1st of the year following each sampling event. The NCDWQ and FERC will review and approve each submitted report. If the benthic invertebrate success biocriterion ( "Good- Fair" rating) is met and the fish community shows reasonable improvement prior to 2020, Progress Energy may request to terminate the aquatic monitoring program, subject to approval by NCDWQ and FERC. 6.0 References Bain, M.

Crutchfield Lead Technical Project Management Specialist Hydro Operations Progress Energy Carolinas, hic, 7001 Pinecre3t Road Ptaleigh,NC 27613 The Division of Water resources (DWR) has reviewed the draft "Study Plan for Aquatic Life Monitoring in Pee Dee River Reach below the Tillery Hydroelectric Plant" dated 5F1508, 15108, along the letter from John Dorney to you dated June 3,, 2002. We are in agreement with the plan as proposed, including the changes suggested in John Dorney's letter. We also note the following: Page 3, Section 3.2, paragraph I — This refers to modifyriug sampling to reflect the most up-to-date approach if there are any changes to NCDWQ's Standard Qualitative Method in future years. We suggest that this wording be changed slightly so that any changes to methods are made only after C*nsultmg NCDWQ to make sue that data collected at different times is still comparable. The letter from John Domey dated June 3, 2008 refers to seven bullets on page 4 of plan, and then suggests a revision to "bullet munber 3," and deleting "bullet number 4" entirely. However, based on the wording revision suggested- I think, they actually mean for you to revise bullet number 4 and drop bullet number 5. You may want to check and make sure there is a clear understanding of what changes to make. We appreciate this opportunity to comment.
