In accordance with Rule 602(c)(1)(ii) (18 CFR 385.602(c)(1)(ii)), set forth herein is a revised Explanatory Statement (dated December 22, 2006) as to the Agreement and this submittal. C-W Explanatory Statement (Rev 1) 12-22-06 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement Agreement Process Effective August 12, 2006, Duke and 69 other participants (Parties) in its relicensing process for the Project entered into the Agreement that resolves issues related to Duke's Application for a New License for the Project that was filed with FERC on August 29, 2006. The participants in this process included state and federal resource agencies, tribes, local governments and associations, businesses, non-governmental organizations, and individuals. The relicensing process achieved a balance of competing resource interests consistent with the public interests in the governing statutes. This outcome was realized by identifying interests, developing objectives and collaborating to develop measures to protect, mitigate and enhance the ecological and cultural resources while providing for other beneficial uses of the Catawba and Wateree rivers and their tributaries, including hydroelectric generation, consumptive uses of Project water and recreation. Multi-party Stakeholder Teams were formed in June 2003 and, with the help of a facilitation team from Kearns & West, Inc., the Stakeholder Teams developed a charter setting forth the ground rules to aid in the decision process and to guide discussions. Over the course of the next three years, the Stakeholder Teams and various study teams, Resource Committees and Ad Hoc Committees met regularly to identify interests and key issues, to develop studies, to analyze study results, and to negotiate alternatives related to the Project. The Stakeholder Teams developed a non-binding Agreement-in-Principle (AIP), and those stakeholders in agreement with that AIP signed it on April 13, 2006 in Rock Hill, South Carolina. Many stakeholders reconvened on July 26, 2006 to sign the binding Agreement. A window of opportunity until August 11, 2006 was also provided for the additional stakeholders to sign the Agreement. In September and October 2006, Parties to the Agreement met to evaluate potential changes to the original Agreement. A draft revised Agreement was prepared by Duke and, in accordance with the Agreement's provisions, submitted on October 23, 2006 to the other Parties for a 60-day opportunity to indicate objections. On November 3, 2006, Duke also informed the Parties of its name change (effective October 1, 2006) from 1 The 70 Parties to the Agreement are Duke Energy Carolinas, LLC; Alexander County, North Carolina; American Whitewater; Area II Soil & Water Conservation Districts; Bowater Incorporated; Burke County, North Carolina; Caldwell County, North Carolina; Carolina Canoe Club; Catawba County, North Carolina; Catawba Indian Nation; Catawba Indian Nation Tribal Historic Preservation Office; Catawba Lands Conservancy; Catawba Regional Council of Governments; Catawba Valley Heritage Alliance; Catawba- Wateree Relicensing Coalition; Centralina Council Of Governments; Chester Metropolitan District; City of Belmont, North Carolina; City of Camden, South Carolina; City of Charlotte, North Carolina; City of Gastonia, North Carolina; City of Hickory, North Carolina; City of Morganton, North Carolina; City of Mount Holly, North Carolina; City of Rock Hill, South Carolina; Crescent Resources, LLC; Duke Energy Corporation; Foothills Conservancy; Gaston County, North Carolina; Great Falls Hometown Association; Harbortowne Marina; International Paper; Iredell County, North Carolina; Kershaw County, South Carolina; Kershaw County Conservation District; Lake James Homeowners; Lake Wateree Association; Lake Wylie Marine Commission; Lancaster County Water & Sewer District; Lincoln County, North Carolina; Lugoff-Elgin Water Authority; McDowell County, North Carolina; Mecklenburg County, North Carolina; Mt.

The operational complexity of the Project required similarly complex evaluations and resolutions particularly on the operations articles and provisions. The Explanatory Statement then covers each resource area in sequence, beginning with operations recommendations. Each resource area begins by summarizing the significant stakeholder interests, reviewing the information from the related studies, discussing the decision process and the significant elements of the decision making, discussing the alternatives considered, describing how the agreements reached in the stakeholder process were captured in the proposed New License Articles and provisions, and, finally, listing some of the major conclusions for that resource area provided in the Comprehensive Relicensing Agreement. 2.0 Comprehensive Relicensing Agreement Overview The Agreement addresses issues involving reservoir elevations, recreation flows, habitat flows, water user needs, drought response, maintenance and emergency response, public information, cultural resources, public recreation facilities, species protection, shoreline management, water quality, compliance gaging and monitoring, and other resource enhancement interests. The Agreement contains the following four distinct aspects. 2.1 Proposed New License Articles - The Agreement contains 19 proposed New License Articles for inclusion in the New License. These articles are clearly identified in Appendix A of the Agreement and are referenced throughout the Agreement. Three of the these articles (Low Inflow Protocol for the Catawba-Wateree Project, Maintenance and Emergency Protocol for the Catawba-Wateree Project, and Shoreline Management Plan) also refer to documents that are included both in the Application for the New License and in Appendices C, D, and J, respectively, that are part of the Agreement and request that the FERC approve these three documents as part of the New License. Section 16.0 of the Agreement acknowledges that the Parties entered into the Agreement with the express objective that the Commission would issue a New License incorporating the proposed license articles without material modification. Material changes to the proposed license articles would upset the balance and benefits negotiated by the stakeholders and may lead to the potential for Parties to withdraw or for the entire Agreement to be terminated. Therefore, the Parties to the Agreement respectfully ask the Commission to regard the Parties' intentions and to adopt the proposed New License Articles as submitted without material modification. 2.2 Non-License Agreement Terms - In addition to the proposed New License Articles, the Agreement contains a number of provisions that the Parties have agreed to undertake outside the New License and hence would not become license conditions or 2 "Provisions" refer to the agreements in the Comprehensive Relicensing Agreement that are not also in the proposed New License Articles. C-W Explanatory Statement (Rev 1) 12-22-06 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement articles. These provisions are contractual in nature and, in many instances, require the Licensee to undertake certain actions. In other instances, these provisions require other Parties to take certain actions or prohibit Parties from engaging in certain activities. Examples include cost-share funding for certain enhancements, providing public information on the Licensee's Web site and telephone system, and undertaking certain actions prior to the New License being issued. 2.3 General Terms - The Agreement also contains a number of general terms and miscellaneous provisions related to administrative matters and to some substantive matters, such as prohibiting Parties from seeking actions inconsistent with the terms of the Agreement. There are terms dealing with the procedures to be invoked if an agency or other entity with regulatory jurisdiction takes an action inconsistent with the Agreement and terms dealing with typical contractual matters such as enforceability, modification, controlling law, etc. 2.4 Attachments to Explanatory Statement Incorporated by Reference - Appended to the Agreement are 15 appendices that are incorporated into the Agreement. These appendices include Proposed License Articles, Parties and Designated Representatives, Low Inflow Protocol (LIP) for the Catawba-Wateree Project, Maintenance and Emergency Protocol (MEP) for the Catawba-Water Project, Definitions, Water Quality Monitoring Plan (WQMP), Abbreviations and Acronyms, Current and Projected (Year 2058) Water Withdrawals and Returns, Catawba-Wateree Public Recreation Amenities and Other Key Land Areas, Shoreline Management Plan (SMP), Template for a Memorandum of Understanding Between the Licensee and States, Counties, and Municipalities, Flow and Water Quality Implementation Plan (FWQIP), Flow, Groundwater and Water Quality Monitoring Summary, Catawba-Wateree Basin Water Management Group (WMG), and Conceptual Conservation Easement Outline. The appendix that the Parties to the Agreement request the Commission incorporate into the New License is Appendix A: Proposed License Articles. The articles refer to the Low Inflow Protocol for the Catawba-Wateree Project, Maintenance and Emergency Protocol for the Catawba-Wateree Project, and Shoreline Management Plan that are included both in the Application for the New License and in Appendices C, D, and J, respectively, that are part of the Agreement. 2.5 Supporting Documentation - The Parties to the Agreement concur that the information developed as part of the stakeholder process, which was included in the Application for New License, supports the protection, mitigation and enhancement measures contained in the Agreement, including the Licensee's obligations set forth in the proposed New License Articles. A variety of studies conducted as part of the relicensing process were completed before the finalization of the Agreement. Those studies, along with other documents and information, serve as the basis for discussions and negotiations leading to the consensus reflected in the Agreement. 3.0 Stakeholder Involvement Process 3.1 Stakeholder Teams Formation 3.1.1 The Licensee elected to use the FERC's Traditional Licensing Process (TLP) and chose to significantly enhance the TLP's public involvement with additional opportunities for stakeholder participation and input. The Licensee filed its First Stage Consultation Document in February 2003 and received initial scoping comments and 568 study requests in the spring of 2003. C-W Explanatory Statement (Rev 1) 12-22-06 2 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement The Licensee also filed a timely Notice of Intent to Relicense with the FERC on July 21, 2003. 3.1.2 In the spring 2003, the Licensee hosted a series of eight public consultation meetings to share information about the Catawba-Wateree River system, describe the relicensing process, and provide opportunities for stakeholders to begin to identify relicensing interests. The Licensee invited and actively recruited interested individuals to participate on relicensing Stakeholder Teams (Teams). Interested individuals submitted interest forms to the Licensee describing their organization, experience, resource interests and which Team they would like join. 3.1.3 The Teams consisted of stakeholders who represented various interests broadly summarized by the categories Adjacent Property Owners, Local Governments, Other Organized Interest Groups, Power Producers, Recreation Groups and Individuals, Water-Dependent Businesses and Federal and State Resource Agencies. 3.1.4 The Licensee invited representatives of the Catawba Indian Nation, state and federal resource agencies and regional non-governmental organizations to join two State Relicensing Teams (SRT) (North Carolina and South Carolina). These Teams met first in June 2003. Using the interest forms submitted by interested individuals, the State Relicensing Teams then helped select the four regional Advisory Groups (AG) (Foothills AG, Metro AG, Piedmont AG, and Lower Catawba AG)3 that began meeting separately in August 2003. The resulting six unique Stakeholder Teams together comprised approximately 160 Team Members representing more than 80 organizations. Nearly all of the individuals that filled out interest forms were eventually added to one or more Stakeholder Teams. 3.2 Principal Purpose of the Stakeholder Process - The overarching purpose of this stakeholder process was to develop a comprehensive agreement addressing the continued operation of the Project. Early in the relicensing process the stakeholders identified and discussed nearly 2,100 interests in the Project. These interests were combined and summarized into 225 composite interest statements that are shown in Attachment A to this Explanatory Statement. The stakeholders used these interests as the basis for identifying and evaluating development and non-development alternatives and recommending an acceptable balance of resource needs. The balance was captured conceptually in a non-binding Agreement in Principle (AIP) (dated April 2006). Team Members who agreed to the AIP provisions worked together to convert the AIP into the Comprehensive Relicensing Agreement (Agreement) for submittal to the Commission. Provisions of the Agreement have been incorporated into the Application for New License. 3.3 Study Teams - Although not formally part of the Stakeholder Process, Study Teams included Stakeholder Team Members as well as resource experts from state and federal resource agencies, the Licensee, and its consultants. The Study Teams oversaw the development and performance of the studies, reviewed and evaluated the 3 The Foothills AG represented the area from the Lake James headwaters through Lookout Shoals Dam; the Metro AG represented the area from Lookout Shoals Dam to the NC-SC state line; the Piedmont AG represented the area from the NC-SC state line to the headwaters of Fishing Creek Reservoir (located at the shoals adjoining Landsford Canal State Park); and the Lower Catawba AG represented the area from the headwaters of Fishing Creek Reservoir to the confluence of the Wateree and Congaree rivers. C-W Explanatory Statement (Rev 1) 12-22-06 3 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement results, and contributed to the study reports and analysis. Study results were reported to the Stakeholder Teams. 3.4 Resource Committees - The Resource Committees (RCs) included study team members, technical experts, and Team Members. The RCs were charged with (i) consolidating and summarizing key study findings, (ii) merging the findings of resource- related studies into a coordinated resource assessment, (iii) identifying relationships with other resource areas (e.g., aquatics and terrestrial), and (iv) providing an assessment of potential resource protection, mitigation and enhancement opportunities supported by study findings. RCs bridged the gap between studies and stakeholders by translating highly technical study data into effective alternatives for the Stakeholder Teams to refer to as they negotiated the terms of the AIP. The RCs were as follows: • Aquatics Resource Committee; • Cultural Resources Resource Committee; • Hydro Operations Resource Committee; • Recreation Resource Committee; • Shoreline Management Resource Committee; • Terrestrial Resource Committee (subsequently combined with the Aquatics RC); and • Water Quality Resource Committee. 3.5 Ad Hoc Committees - Ad Hoc Committees were formed as a means to address specific issues raised in the Teams that couldn't be resolved efficiently by the facilitated discussion in the larger Teams. These Committees, made up of selected Team Members with particular resource expertise or interest in the subject at-hand, conducted detailed discussions and brought recommendations back to the Teams. Committee membership was often drawn from more than one Team. These Committees provided regular status reports to and gathered input from the Stakeholder Teams as the negotiations proceeded. During 2004 and 2005, these Committees sometimes met several times a month. The Ad Hoc Committees are listed below: • Aquatics/Terrestrial Ad Hoc Committee (to finalize the aquatic flows and species protection plans); • Recreation Ad Hoc Committee (to finalize the recreation facilities package); • CHEOPSTm Ad Hoc Committee (to develop operating scenarios, review adjustments in the Low Inflow Protocol, and coordinate with the other Committees and Teams); • Sections 1/16 Ad Hoc Drafting Committee (to draft the General Agreements and Procedures related to implementing the Agreement); • Land Ad Hoc Committee (to integrate and coordinate the various land interests in the negotiations); • Water Withdrawers Committee (to address issues related to water withdrawals, procedures for intake approvals, and a fund to protect and improve the storage capability of the reservoirs and water quality); and • Final Agreement Conversion Committee (to oversee the conversion of the AIP into the Comprehensive Relicensing Agreement). C-W Explanatory Statement (Rev 1) 12-22-06 4 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 4.0 The Project - Developments and Operation 4.1 Project Overview - The Catawba-Wateree Project is located on the Catawba River in North Carolina and on the Catawba and Wateree rivers in South Carolina. The Catawba River begins in western North Carolina and flows easterly and southerly into South Carolina, where it joins Big Wateree Creek to form the Wateree River. The Project has 11 developments, including: Bridgewater, Rhodhiss, Oxford, Lookout Shoals, Cowans Ford, Mountain Island, Wylie, Fishing Creek, Great Falls-Dearborn, Rocky Creek-Cedar Creek, and Wateree. The Project spans more than 225 river miles and encompasses approximately 1,795 miles of reservoir and island shoreline within nine counties in North Carolina and five counties in South Carolina. In providing cooling water to more than 8,100 megawatts of fossil and nuclear-fueled generation, it is the backbone of Duke's power generation system in the Carolinas. The Project also provides 831 megawatts (MW) of renewable hydropower, enough electricity to power 116,000 average homes. The reservoirs provide industrial process and cooling water and drinking water to more than 1.3 million people. The demand for public water supply is expected to increase by over 200 percent in the next 50 years. Of particular interest to the stakeholders was increasing flows in the regulated river reaches and the bypassed reaches to enhance aquatic communities, river-oriented recreation, and aesthetics. 4.2 Project Operations - A Project flow routing schematic is shown in Attachment B to this Explanatory Statement. Although the interests and use requirements are typically listed reservoir-by-reservoir, the Project must be operated as an integrated "stair- stepped" system to use its limited storage to satisfy the local demands on the Project. Geographic and demographic factors complicate this approach because the local demands do not often line up with the local inflows and storage capabilities. For example, the population centers and heaviest water demands are currently in North Carolina, but flows from only about 60 percent of the North Carolina portion of the Basin enter the Catawba-Wateree River in North Carolina. 4.3 Bypassed Reaches - The bypassed reaches, which received considerable attention in the stakeholder discussions, are: 4.3.1 Catawba River Bypassed Reach and Paddy Creek Bypassed Reach at the Bridgewater Development (Lake James); 4.3.2 Mountain Island Bypassed Reach at the Mountain Island Development (Mountain Island Lake); 4.3.3 Great Falls Long Bypassed Reach and Short Bypassed Reach at the Great Falls-Dearborn Development (Great Falls Reservoir); and 4.3.4 Wateree Spillway Channel at the Wateree Development (Lake Wateree). 4.4 Regulated River Reaches - The regulated river reaches, which also received considerable attention in the stakeholder discussions, are: 4.4.1 Bridgewater (Lake James) Regulated River Reach; 4.4.2 Oxford (Lake Hickory) Regulated River Reach; 4.4.3 Lookout Shoals Regulated River Reach; 4.4.4 Wylie Regulated River Reach; and 4.4.5 Wateree Regulated River Reach. C-W Explanatory Statement (Rev 1) 12-22-06 5 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 5.0 Operations Articles and Agreements 5.1 Overview 5.1.1 The following eight proposed License Articles in the Comprehensive Relicensing Agreement have strong relationships to one another and define the Project's proposed operation. 5.1.1.1 ARTICLE - Reservoir Elevations 5.1.1.2 ARTICLE - Spring Reservoir Level Stabilization Program 5.1.1.3 ARTICLE - Recreation Flows 5.1.1.4 ARTICLE - Minimum Flows (for aquatic resources) 5.1.1.5 ARTICLE - Wylie High Inflow Protocol 5.1.1.6 ARTICLE - Flows Supporting Public Water Supply and Industrial Processes 5.1.1.7 ARTICLE - Low Inflow Protocol for the Catawba-Wateree Project 5.1.1.8 ARTICLE - Maintenance and Emergency Protocol for the Catawba-Wateree Project 5.1.2 Stakeholder Evaluation - Stakeholders actively participated in developing the technical content (i.e., study results, evaluations, and recommendations) and, subsequently, the proposed license articles. As a result, the preliminary technical content was developed independently for each proposed license article by different Stakeholder Teams and Resource Committees. The preliminary technical content for each article was also developed independently of other operational considerations: the initial minimum continuous flows were based solely on aquatic needs; the flows for public water supply were based solely on the water suppliers' existing and projected flow needs; and the recreation flows solely on the Recreation Flow Study.4 At a later time these flow targets were integrated, analyzed by computer modeling as applicable, evaluated against acceptance criteria pre-determined by the different Teams and Resource Committees, and adjusted as needed into an operational scenario that would ensure that the requirements for each of these eight proposed operations articles could be simultaneously satisfied by the physical system. There was enough overlap of Team Members on the Resource Committees, in addition to participation by the Licensee and the process facilitation team, to keep the various Committees regularly informed of the numerous parallel activities. All of the technical content supporting these proposed articles, as well as the principal tools for their evaluation, were provided by existing information; the Licensee's relicensing studies resulting from stakeholder study requests; computer models (CHEOPSTM 5 and water 4 Recreation Flow Study - June 27, 2006. 5 CHEOPSTM is a computer-based hydroelectric operations model that assesses the impacts of simulated hydroelectric project operating conditions on flows and reservoir levels.

As a result of these considerations, and recent stakeholder experience with the drought-of-record for the region, which occurred between 1998 and 2002 in this and the neighboring Yadkin River basins, the stakeholders generally accepted the following as their highest priority operations interests: 5.1.3.1 Potable Water - Maintain potable water supplies for the more than 1.3 million people in cities and towns that are dependent on the Project for their water supplies (including Charlotte, the Carolinas' largest city with a population of more than 540,000 people) (i.e., keep elevations above the Critical Reservoir Elevations (CRE)7) for the term of the New License. This also required that river flows not drop below critical intake and effluent discharge support levels; 5.1.3.2 Electricity - Maintain electricity supply by assuring cooling water for the thermal plants on the Project's reservoirs (more than 8,100 MW) (i.e., keep reservoir elevations above the CRE); 5.1.3.3 Fish and other Aquatic Organisms - Maintain flows in the regulated river reaches and re-watered bypassed reaches to prevent long-term or irreversible damage to aquatic communities in these reaches and to maintain water quality (i.e., keep Minimum Continuous Flows above the Critical Flowss); and 5.1.3.4 Drought Tolerance - Assure that the recommended operational scenario would not result in a Low Inflow Protocol Stage 4 Condition9 during the next 50 years as assessed by using the past-51- year-period-of-record inflows, adjusted to account for increased water supply demands1o, and increased sedimentation into the reservoirs to 6 The Performance Measures Evaluation Spreadsheets are included in the PM&E Module included in the Application for New License. 7 Critical Reservoir Elevation (CRE) - the highest water level in a reservoir below which any Large Water Intake used for Public Water Supply or industrial uses, or any regional power plant intake located on the reservoir, will not operate at its Licensee-approved capacity. a Critical Flows - the minimum flow releases from the hydro developments that may be necessary to: a. Prevent long-term or irreversible damage to aquatic communities consistent with the resource management goals and objectives for the affected stream reaches; b. Provide some basic level of operability for Large Water Intakes located on the affected stream reaches; and c. Provide some basic level of water quality maintenance in the affected stream reaches. 9 A Low Inflow Protocol (LIP) Stage 4 Condition is declared when the Remaining Usable Storage in the reservoir system is small and can be fully depleted in a matter of weeks or months. Owners of Large Water Intakes are asked to implement Emergency Water Use Restrictions. Groundwater recharge may also contribute to the declining reservoir levels. For these reasons when in LIP Stage 4, the Licensee may not be able to ensure that releases from its hydro developments will meet or exceed Critical Flows or that reservoir elevations will be greater than or equal to the Critical Reservoir Elevations. 10 Water Supply Study; April, 2006.

C-W Explanatory Statement (Rev 1) 12-22-06 7 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement represent month-by-month inflow conditions for the ensuing 51-year period. 5.1.3.5 Other Abnormal Conditions - Anticipate possible abnormal conditions (in addition to low inflows) and outline in the Maintenance and Emergency Protocol the mitigation actions and communications the Licensee will take during those abnormal conditions. 5.2 Operations Scenario Development As noted in the Paragraphs below, the preliminary operations recommendations for flows, reservoir levels, and Low Inflow Protocol stage triggers and water use reductions were first developed independently based on the resource targets and interests for those specific operations areas. It remained to input these into the model of the actual system, and, using realistic inflows, to test whether these preliminary independent recommendations could actually be satisfied by the system. In the result, it was found that many of the recommendations could be satisfied, but others could not. Resolution of the latter required considerable analysis, innovation, and negotiation. Here's how the eventual preferred operations scenario evolved. An operations scenario has six elements: • Reservoir elevations: targets, minimums and maximums; • Minimum flows; • Recreation flows and schedules; • Low Inflow Protocol stage triggers and water-use reductions; • Water supply demands and returns (current and future); and • Reservoir sedimentation (current and future). By agreement, a scenario "failed" if it could not meet all four priorities in Paragraph 5.1.3 or could not sustain all of the input license flows and/or reservoir level limitations for that scenario for the entire period of record. Even if a scenario didn't fail, it "had problems" if reservoir levels were too frequently off the normal targets, the LIP was activated too often, water supply safe-yield reductions were too great, or hydro generation or value losses were too large to be acceptable to stakeholders. Predictably, failures and problems occurred most frequently for dry or drought conditions. Experience using the CHEOPSTM operations model was gained concurrently with the development of the independent operations recommendations. But with an infinite number of possible operations scenarios, we needed a place to start. For the Catawba- Wateree System, water storage (and flexibility to use it) was fundamental to addressing the interests and water demands. With this recognition, the CHEOPSTm Ad Hoc Committee worked with a Water Storage Flexibility Spectrum (WSFS) to consider various operations scenarios. The spectrum ranged from the storage flexibility (greatest) with no license limitations to the flexibility (none) provided if there were no dams. The realistic spectrum ranged between Baseline conditions (how the Project is currently operated) and Run-of-River (outflows equal inflows). Except for a few stakeholders with interests in Run-of-River, most stakeholders acknowledged that the eventual preferred scenario would be somewhere within this realistic spectrum. All scenarios looked out 51 years using day-by-day inflows from the previous 51-year period-of-record, adjusted for increased water withdrawal demands and increased reservoir sedimentation. Conservatism was added because the period-of-record drought C-W Explanatory Statement (Rev 1) 12-22-06 8 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement occurred near the end of the period-of-record inflows, and, therefore, in the projected 51 years, the timing of the worst drought inflows corresponded to the timing of greatest projected water supply needs and greatest increased sedimentation. Understanding the total system storage was complicated by both the unevenness of the storage locations in the Project (86 percent of the Project's Total Usable Storage is in lakes James, Norman, Wylie, and Wateree) and the unevenness of the demands on storage. It was further complicated by the unevenness of the inflows due to the large geographic area covered by the Project. These three factors caused the scenarios to be driven more by certain inputs and led to "choke" points in the system. To speed model processing time, the Committee identified three levels of analysis, each with increasing complexity and processing time. The Level 1 analysis used only flow inputs and calculated output for three 3-year periods - typical wet, normal and dry (but not the driest). Level 2 included the full 51-year period-of-record inflows and outputs, and Level 3 looked at output sensitivities to several variables (e.g., future inflows (very sensitive)). With the Level 1 analysis the Committee first looked at Baseline and Run-of-River scenarios plus four additional Information Scenarios that each optimized the scenario elements for one of the following: habitat, water use, river-based recreation flows, and property interests. Graphical representations of the reservoir levels output also helped stakeholders determine if their water quantity-related interests were being met. Along with the flows, reservoir elevations, and energy outputs, the CHEOPSTm raw output was processed to calculate a Performance Measure Evaluation Spreadsheet (PMES). The elements of the PMES (developed by the CHEOPSTm Ad Hoc Committee) were grouped into the relevant stakeholder interests to evaluate performance for fish and aquatics interests, recreation interests, water users' interests, energy production and other interests. The energy production performance measures were calculated for the Project as a whole, but the other interests were calculated for each development and affected river reach. When the preliminary recommended scenario elements were available, the Committee had an improved knowledge of system limitations. Through more than 16 scenarios, the CHEOPSTm Ad Hoc Committee and ultimately all the stakeholders, reviewed the output and performance measures to conclude on the preferred operations scenario. Key factors in reaching the preferred scenario are noted in the appropriate operations areas below. 5.3 Reservoir Elevations 5.3.1 Interests Affecting Level Management -The proposed Reservoir Elevations License Article would establish normal operational elevation limits in the license for the first time, although the Licensee has voluntarily managed the elevations to a set of guide curves over the last couple of decades. Reservoir elevations are managed to support water quality, storage capacity, thermal plant operations, hydro operations flexibility, water supply, habitat protection for near- shore lands and shallow-water areas, and spring fish spawning, as well as a diverse set of recreation interests and aesthetics, which in turn often support community economic interests. Reservoir levels are also managed to address downstream interests - flows for aquatic communities, recreation, water supply, and water quality. All of these interests were represented in the Stakeholder Teams. C-W Explanatory Statement (Rev 1) 12-22-06 9 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 5.3.2 Studies - The results of several studies had to converge to evaluate this and other operational articles. The CHEOPSTM Operation Simulation Model was developed to evaluate the water storage capability of the system to operate under various scenarios and therefore provide stakeholders with information on how well or poorly any particular scenario met their individual and collective interests related to water quantity. Input to the CHEOPSTM model includes LIP stages, triggers and flow reductions; water withdrawal projections, Critical Reservoir Elevations, recreation flow levels and schedules, minimum continuous aquatic flows, Critical Flows, hydro unit performance, reservoir bathymetry, sedimentation projections, and 51-year inflow history. 5.3.3 Decision Process 5.3.3.1 Competing Stakeholder Interests -Although there were a large number of interests and considerations in the development of the proposed Reservoir Elevations License Article, those that dominated the considerations (both as a combination of priorities and impacts on other priorities) were as follows. The interests related to lake recreation, aesthetics, community economic interests, fish spawning and near-shore habitat enhancement, and water supply, as well as better assurance in providing required downstream flows to enhance aquatic resources, river recreation, and assure water supply and water quality, argued for higher reservoir levels, more restricted level variation, and elimination or reduction of the winter drawdowns at the four largest storage reservoirs. Hydro operations flexibility and flood management interests argued for increased level variation, and flood management interests argued for lower reservoir levels, taking into consideration the high flow impacts of upstream reservoirs on downstream reservoirs. 5.3.3.2 Sensitivities - The sensitivity of impacts on other interests to the Normal Maximum Elevations was small; these elevations were set to full-pond for all the reservoirs. The sensitivity of hydro operational impacts, flood management and providing minimum flows for aquatic communities to the Normal Minimum Elevations and Normal Target Elevations (particularly on lakes James, Norman, Wylie, and Wateree) was significant. There was also a requirement to balance the potential for flooding (particularly on Lake Wateree) with the need to maintain levels above the Critical Reservoir Elevations which is of particular concern during drought conditions. 5.3.4 Other Alternatives Considered - Higher Normal Target Elevations, up to full pond, were considered but not included because of the increased potential for flooding but with no real improvement on recreation use and only slight improvement in aesthetics. A more restricted operating band was considered but not included because it further impacted the hydro developments' ability to load follow and provide peak power generation, two of the key benefits of the Project for the electric system, and it only produced a slight improvement in aesthetics. Further decreasing or eliminating the spring drawdowns, including run-of-river operations at or near full pond, was considered but not included because of the decreased ability to manage flooding and the further reductions on the hydro developments' ability to produce peaking energy and follow load. The ability to use the reservoirs for flat-water recreation during the off-peak C-W Explanatory Statement (Rev 1) 12-22-06 10 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement recreation season (i.e., October 1 through March 31) was addressed by limiting the depths of the winter drawdowns to ensure that at least one (and in most cases, several) public motor boat launching ramps remained operational during the winter drawdown. 5.3.5 Article - All of the normal target, minimum and maximum reservoir elevations in the preferred operations scenario are included in the proposed Reservoir Elevations License Article. 5.3.6 Conclusions - The proposed Reservoir Elevations License Article identifies a balance of stakeholder interests that is consistent with the system's capability to meet the requirements in this and the seven other proposed operations articles. In general the article's content results in the following. 5.3.6.1 For the first time the License will have a fixed Normal Operating Range for reservoir elevations. 5.3.6.2 The Normal Target Elevations will be at or slightly higher than the guide curve elevations that have been used voluntarily for the past 15 years. 5.3.6.3 The four large reservoirs with winter drawdowns (Lake James, Lake Norman, Lake Wylie, and Lake Wateree) will continue to have drawdowns, but they will be regulated by the License, be reduced in the elevation drop, and will begin later and end earlier to keep higher reservoir levels for a longer period during the spring, summer, and fall recreation seasons. 5.3.6.4 The day-to-day elevations will fluctuate more frequently than in the past due in large part to the significantly higher minimum flow demands in the proposed Minimum Flows License Article. However, the fluctuations will be limited to a relatively small range. 5.4 Spring Reservoir Level Stabilization Program 5.4.1 Interests Influencing the Stabilization Program - The Licensee has been voluntarily implementing a spring reservoir level stabilization program in the four reservoirs with winter drawdowns (Lake James, Lake Norman, Lake Wylie, and Lake Wateree) in consultation with state resource agencies for more than 20 years. Stakeholders had a broad interest in protecting and enhancing reservoir near-shore spawning habitat. Addressing this broad interest with more specifics, the resources agencies were interested in formalizing the stabilization program (putting it in the License) and fine tuning the initiation triggers to be more closely linked to the beginning of spawning for the principal species of interest (bass) in each of the four reservoirs. 5.4.2 Studies - No studies were completed to specifically address this program; however, the fish communities in the reservoirs were generally assessed in the Reservoir Fisheries Assessment" as part the Aquatics 01 study plan. In addition, the Operations 02 (Reservoir Level) study evaluated lake level fluctuations during fish spawning seasons for the period-of-record, and the 11 Relationships of Fish Community Characteristics to Environmental Parameters in the Catawba-Wateree Reservoirs (Aquatics 01). C-W Explanatory Statement (Rev 1) 12-22-06 11 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement Aquatics 02 (Reservoir Fish Habitat) study was completed to quantify the shallow-water fish habitat gains or losses with changes in water levels. 5.4.3 Decision Process - The present voluntary implementation of the program was based on a temperature trigger of Lake Wateree reaching 65°F or observations of actual fish spawning. Once the trigger was reached in Lake Wateree, there was a staged implementation schedule for the other three reservoirs. A small group of interested agencies and the Licensee revised the program to include separate temperature triggers (or direct observations of spawning) at each individual reservoir with winter drawdowns. The program was reviewed with the Stakeholder Teams. 5.4.4 Alternatives Considered - No significant alternatives were considered other than discussions about the consultation protocols and where to locate the temperature monitors. The conclusions appear in the proposed Spring Reservoir Stabilization Program License Article and in the Agreement. Consideration was given to implementing the program on additional reservoirs, but the stable levels on those reservoirs make that unnecessary. 5.4.5 Article and Provisions - The proposed License Article formalizes the program structure and identifies the consultation requirements for implementing the program and for developing any future modifications to submit for Commission approval. The Agreement also adds some additional context about where to locate the monitors and how the locations will be determined in cooperation with state agencies. 5.4.6 Conclusions - The already successful stabilization program promoting fish spawning in the reservoirs with winter drawdowns has been formalized and enhanced. There is no need for stabilization in other reservoirs because they will have much less level variability over the entire calendar year, and these levels were already stable during spawning. 5.5 Recreation Flows 5.5.1 Interests Influencing Recreation Flows - The Recreation Use and Needs Study 12 indicated a considerable interest in river-based recreation, and the Stakeholder Team interests supported that conclusion. The interests were paddling, including whitewater experiences, and angling both by wading and by boat. The angling was of particular interest in the stocked trout fishery of the Bridgewater (Lake James) Regulated River Reach. Increased recreation flows delivered mostly on weekends would reduce the capability for the Project to provide peaking and load following during times when those capabilities were more valued. Recreation flows also expend the water storage in the reservoirs and contribute to lowering reservoir levels during periods of low inflow (but to a lesser extent than the minimum continuous flows). 5.5.2 Studies - The Recreation Flow Study tested a range of potential recreation flows with an experienced set of paddlers and anglers to identify the optimum and minimum recreational flows in the reaches below the Bridgewater, Oxford, Great Falls, Wylie, and Wateree developments. Because of the interest in wade fishing below Bridgewater, a maximum acceptable recreational flow was also assessed at that location. 12 Catawba-Wateree Recreation Use and Needs Study (Rec 01). C-W Explanatory Statement (Rev 1) 12-22-06 12 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 5.5.3 Decision Process - The Recreational Flow Study Team, many of whose members were participants in the recreational flow assessments, identified the optimum flows and recommended the flow schedules. Their recommendations were regularly reviewed by the Stakeholder Teams and adjusted accordingly. One of the last recommendations was to evenly divide the number of days at Bridgewater with flows preferred by anglers and flows preferred by paddlers to fairly accommodate both interests. The upper end of the acceptable flow range for float angling and the lower end of the acceptable flow range for paddling overlap. The recreational flow release schedule for each of the five developments includes 10 hours of discretionary flow scheduling (20 hours at Great Falls), and the fixed schedules may be readjusted temporarily each year by participants in the Recreational Flow Schedule Planning meeting. 5.5.4 Alternatives Discussed - Because the proposed flow rates are at or are very close to the optimum rates developed in the study, there were no significant alternative flows considered. While more frequent recreation flows may have been preferred by some stakeholders, the proposed schedule provided acceptable recreation opportunities. Even though the addition of recreation flows, primarily on weekend days, reduces the energy production values of the Project, these impacts tended to be small compared to the other flow demands. Small increases or decreases in flow rates and scheduled times tended not to have big impacts on the operational scenarios. 5.5.5 Articles and Provisions - The flows and the flow schedules are captured in the proposed Recreation Flows License Article along with the requirement for the annual Recreational Flow Schedule Planning meetings. Limits are established for small temporary alterations in flow rates and schedules within which Commission approval is not required. Details and organization of the Recreational Flow Schedule Planning meeting are provided in the Agreement to allow flexibility to make improvements in the meeting processes. 5.5.6 Conclusions - Below are some of the important measures in the Agreement. 5.5.6.1 Recreational flows will be released at five developments to provide paddling opportunities in six reaches, including the long and short bypassed reaches at Great Falls. 5.5.6.2 River-based recreationists will have a dependable schedule (posted on the Licensee's Web site) for when the flows for recreation will be released in the river. 5.5.6.3 Forecasts of near-term unscheduled river flows posted on the Licensee's Web site and toll-free telephone system several days ahead of their release will add to the scheduled opportunities. 5.5.6.4 Some flow schedules will remain discretionary to support specific community-related events. 5.5.6.5 Each year the Licensee will convene a group of river- based recreation users and specialists to review the previous year's schedules and plan the current year's schedules and community events. C-W Explanatory Statement (Rev 1) 12-22-06 13 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 5.5.6.6 Canoe and kayak access points will be added or enhanced along the river reaches during the first 20 years (mostly the first five years) of the New License (see the proposed Recreation Management Plan License Article). 5.6 Minimum Flows 5.6.1 Interests Influencing Minimum Flows - Stakeholders had general interests in protecting and enhancing fish populations and aquatic communities in the rivers and tributaries. They also had general interests in reestablishing migration of populations of native, naturally reproducing diadromous species to their historic reaches (including American shad, hickory shad, blueback herring, American eel, striped bass, Atlantic sturgeon and shortnose sturgeon). The Aquatics Resource Committee converted these broad species interests into target species and developed detailed flow-versus-habitat relationships to specifically address those species' needs. The Aquatics Resource Committee considered minimum flows at all 11 developments, but was more focused on flows from developments that fed regulated river reaches and bypassed reaches rather than directly into the next downstream reservoir. It was also necessary to address South Carolina requirements for adequate downstream navigation flows in the regulated river reaches. Some stakeholders also had interests in establishing run-of-river operations and had a related interest to adapt Project operation to better approximate unregulated (i.e., natural) conditions especially during spring spawning. 5.6.2 Studies - The aquatics related studies 13 provided information in two broad categories: (i) assessments of the existing aquatic communities in regulated river reaches, tributaries, and bypassed reaches and (ii) assessments of aquatic habitat-versus-flow relationships based on using the Instream Flow Incremental Methodology (IFIM). The IFIM assessments included both one- dimensional and two-dimensional models. The two-dimensional models were used for reaches with more complicated hydraulics and streambed topologies such as the shoals near Landsford Canal State Park and the Great Falls Long Bypassed Reach. To effectively study more than 100 miles of regulated river habitat, the Licensee conducted video helicopter surveys of all river sections. These videos helped Study Team members pick potential study sites and transects which were subsequently confirmed with site visits. Three two- dimensional study sites were modeled along with 104 one-dimensional transects and 11 wetted-perimeter transects. A total of 37 aquatic species/life stages (including fish, macroinvertebrates, slider turtle, and the Rocky Shoals spiderlily) were evaluated. 5.6.3 Decision Process 5.6.3.1 Aquatics Resource Committee Efforts - The Aquatics Resource Committee and Study Team held more than 60 all-day meetings during relicensing. At first, the meeting topics focused on 13 Fish Community Assessment (Aquatics 01), Reservoir Habitat Assessment (Aquatics 02), Diadromous Fish Study (Aquatics 03. 1), Fish Passage Feasibility (Aquatics 03.2), Instream Flow Assessment (Aquatics 04), Fish Entrainment Evaluation (Aquatics 05), Mussel Survey (Aquatics 06), Macrobenthic Survey (Aquatics 07), Snail Survey (Aquatics 07), Crayfish Survey (Aquatics 07). C-W Explanatory Statement (Rev 1) 12-22-06 14 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement site visits, selection of appropriate study methodologies, study plan development, and selection and approval of study sites and transects. As the fieldwork was completed and results presented, the Committee focused on using the modeling tools that were developed to evaluate various flow regimens and ultimately determine minimum continuous flow and critical flow recommendations. During these deliberations, the analysis focused almost entirely on the habitat goals of the state and federal resource agencies (typically flows providing 80 percent of unregulated (i.e., natural) Index C habitat) regardless of whether or not the existing equipment at the developments could actually operate at the recommended flows or whether the flows could be reliably coordinated among all the developments. 5.6.3.2 Interactive Time Series Analysis OTSA) Spreadsheet to Relate Flows and Habitat - Based on the studies and additional agency information and input, the Committee identified the aquatic species (i.e., fish, m acroi nve rteb rates, slider turtles and the Rocky Shoals spiderlily (a South Carolina-listed plant)) for each of the regulated and bypassed river reaches. The Licensee, with input and oversight from Committee members, developed the ITSA tool to evaluate the IFIM habitat results for various flow regimes. The ITSA program operates in a Microsoft Excel spreadsheet and provides indices to compare the habitat provided for a given flow regime to both the existing regulated flow regime and the unregulated flow regime. It uses a habitat-duration-curve metric such as Index C or Area-Under-the-Curve (AUC) to compare the habitat availability over time between one scenario and another. Index C, the principal metric chosen for use by the Committee, is defined as the mean of the total weighted useable area (WUA) values between 50 and 100 percent exceedance on the habitat duration curve. There is an individual Index C value associated with each study subreach, for each flow, for each month, and for each species and life stage. The portion of the habitat duration curve between 50-100 percent exceedance represents the lower half of the WUA values. The lower half of the WUA values can be the result of flows that are either too high or too low depending on the species and life stage being evaluated. Using Index C as a metric is relevant because it is associated with the lower or more critical end of the habitat scale and, as such, is a conservative means of evaluating aquatic habitat gains. The AUC metric is very similar to Index C except that it is the total area under the habitat duration curve between 50-100 percent exceedance, instead of the mean value between 50-100 percent exceedance. 5.6.3.3 Flow Development Process - The Committee worked towards a goal of attaining flows providing 80 percent of unregulated Index C habitat and used the ITSA Spreadsheet to develop recommended flows. This involved an iterative process to determine aquatic species/life stages that showed the largest sensitivity to changes in flow of each modeled reach. The Committee then used habitat results for these driver species to establish a preliminary flow recommendation for each development. With that preliminary recommendation, the Committee then reviewed the ITSA C-W Explanatory Statement (Rev 1) 12-22-06 15 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement Spreadsheet habitat results at that flow for all of the other species and guilds and made flow adjustments if necessary. Seasonal variations in flows were also considered. The process required some trial and error, but effectively determined the desired flows from each development. 5.6.3.4 Peaking and Velocities Profiles - Once the Committee had reached a flow recommendation, it reviewed individual transect velocity profiles using the RHABSIM model to consider whether or not the preliminary recommended flows needed further adjustment. Most were left as calculated by the ITSA Spreadsheet. The Committee then used "dual-flow" analysis to assess potential habitat losses due to peaking operations to consider whether or not further flow adjustments were suggested. Both analyses informed, but did not drive the flow recommendations with the exception of spring stable flow periods recommended below Lake Wateree (see next Paragraph). 5.6.3.5 Additional Flow Considerations: Wateree Spring Stable Flow Periods - To enhance spring spawning conditions for diadromous fish species in the Wateree River (extending 76.8 miles below the Project's most downstream development), the Committee recommended and the Licensee agreed to endeavor in good faith to provide two, 10-day stable flow periods each spring, one between February 15 and April 1 and another between April 1 and May 15, if the inflow conditions would sustain the flows without violating reservoir level requirements. 5.6.3.6 Additional Flow Considerations: Wateree Floodplain Inundation - To enhance floodplain spawning habitat (e.g., blueback herring and other species) below the Wateree Development, the Committee recommended that, when high inflows created spill conditions at Wateree Hydro, the flow from the Wateree Development be reduced gradually to extend the duration of floodplain inundation to the extent possible to simulate natural conditions and still maintain reservoir level requirements. 5.6.3.7 Catawba River Bypassed Reach - Both the analysis and the determination of appropriate flows for this reach were complicated by several factors. The most significant factor was Catawba Dam flow release temperatures. Releases that are too cold were predicted to have a negative impact on a population of mussels in the downstream portion of the bypassed reach; while higher volume releases that are too warm were predicted to have a negative impact on the stocked cold-water trout fishery below the point at which the Catawba River Bypassed Reach joins the Bridgewater Regulated River Reach (5.6 mi downstream from the Catawba Dam). Detailed temperature and flow models were used to evaluate many different scenarios to find an acceptable balance between mussel and trout habitat. Although the agencies' interest was in having a self-sustaining (not stocked) trout fishery in the Bridgewater Regulated River Reach, the water quality model temperature results showed that the capacity of Lake James to deliver cold water was not always adequate for that purpose. This C-W Explanatory Statement (Rev 1) 12-22-06 16 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement was particularly the case during high inflow conditions when warm water flow contributions from tributaries (such as Muddy Creek) elevate temperatures. 5.6.3.8 Great Falls Bypassed Reaches - In the Great Falls Short Bypassed Reach (0.8 mi long), flow recommendations were made based on 1-D IFIM modeling results in the upper portion of the reach. In the Great Falls Long Bypassed Reach (2.2 mi long), flow recommendations were based on 2-D IFIM modeling results from the upper and lower portions of the reach, a wetted area photogrammetry study of the entire reach, and a wetted perimeter study of the heavily braided middle portion of the reach. 5.6.3.9 Critical Flows for the Low Inflow Protocol - Using principally the ITSA Spreadsheet, the Committee determined the Critical Flows to be used in connection with the Low Inflow Protocol and the Maintenance and Emergency Protocol for each regulated river reach and each re-watered bypassed reach. All Critical Flows except from the Linville Dam (Bridgewater) were established at a 95 percent exceedance flow using the 51-year period-of-record inflows. The flows at Linville Dam were set at a 97 percent exceedance flow based on the smaller drainage area associated with Lake James, the first reservoir on the system. 5.6.3.10 Flow Iterations - As described in Section 5.2, many flow and reservoir level recommendations converged and were analyzed in the CHEOPSTM computer model. When scenarios consisting of a set of flow and reservoir level recommendations did not meet established criteria (see Section 5.1.3), flow, reservoir level and LIP recommendations were adjusted until all criteria were met. The result yielded the minimum continuous flows presented in the Agreement. 5.6.4 Alternatives Discussed 5.6.4.1 Potential Ten-Year License Amendments - Filing the Wateree Floodplain Inundation provisions as a proposed License Article was considered, but ultimately rejected because of the difficulty of establishing Commission-enforceable rules before having experience with its implementation. The same situation existed for the Wateree Spring Stable Flow periods. In both cases it was agreed that the appropriate Parties would evaluate the experience with both protocols after ten years and consider if the ten-year experience was adequate to establish enforceable rules for either or both flow regimens. If the experience did lead to appropriate rules, the Licensee would propose New License Article(s) as an amendment to the New License at that time. 5.6.4.2 Bypassed Reaches - The possibilities of providing flows in the Paddy Creek Bypassed Reach (Bridgewater, 0.5 mi long) and the Mountain Island Bypassed Reach (Mtn. Island Development, 0.5 mi long) were considered by the Aquatics Resource Committee. However, because of the limited potential increase in overall habitat and the negative impacts of bypassing water on hydro generation, it C-W Explanatory Statement (Rev 1) 12-22-06 17 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement was agreed that, in exchange for adequate mitigation, no flow in these bypasses would be required. There were also no recommended flows in the Wateree Spillway Channel (Wateree Development). In the course of the Aquatics Resource Committee discussions, the USFWS stated that NOAA Fisheries had identified the Wateree Spillway Channel (1.3 mi long) as prime shortnose sturgeon spawning habitat. Because of the large capital cost of installing flow delivery devices, lost generation, and minimal habitat gains (increases in shortnose sturgeon spawning habitat of approximately 0.2 percent), no flows were recommended by the Aquatics Resource Committee for this spillway channel. 5.6.4.3 Oxford and Lookout Shoals - Oxford has a relatively short regulated river reach (2.8 mi long) that would require a large capital expenditure plus substantial loss of hydro value to meet the desired habitat flows. Although the minimum flows at Oxford were increased over existing flow conditions, they fell short of habitat targets, and instead, it has been agreed to provide mitigation. There is a similar situation at Lookout Shoals where the area downstream of the dam (up to 1.3 mi long) is seasonally riverine depending on Lake Norman's level. 14 Again, it was agreed to provide an increase in the continuous minimum flows plus mitigation for this location. 5.6.5 Article - The seasonal minimum continuous flows for all the developments are provided in the proposed Minimum Flows License Article. The Agreement includes the potential to file two additional proposed New License Articles after ten years of operational experience. 5.6.6 Mitigation - To mitigate for the Project impacts to the Paddy Creek Bypassed Reach, the Oxford Regulated River Reach, the Lookout Shoals Regulated River Reach and the Mountain Island Bypassed Reach, the Agreement identifies a mitigation package for North Carolina. The mitigation package was based on the methodology described in Stream Mitigation Guidelines developed by the U.S. Army Corps of Engineers, the U.S. Environmental Protection Agency, the North Carolina Wildlife Resources Commission, and the North Carolina Division of Water Quality in 2003. The same methodology was used to formulate a mitigation package for South Carolina to mitigate for unavoidable Project impacts to the Wylie Regulated River Reach (25.6 mi long), the Great Falls Long and Short Bypassed Reaches, and the Wateree Spillway Channel. These mitigation packages will be recommended for consideration and approval in the 401 Water Quality Certification processes for each state. 5.6.7 Conclusions - Below are some of the important measures in the Agreement. 5.6.7.1 Continuous minimum flows will be provided in three bypassed reaches with highest stakeholder interest for the first time in more than 80 years. 14 The releases from the Lookout Shoals Development flow directly into Lake Norman. During Lake Norman's winter drawdown, the very short reach just below the Lookout Shoals Development has some characteristics of a regulated river reach. C-W Explanatory Statement (Rev 1) 12-22-06 18 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 5.6.7.2 The Project's principal regulated river reaches will have significantly higher aquatic habitat flows than under current conditions. 5.6.7.3 Typically the Wateree Regulated River Reach will have two, 10-day spring stable flow periods to enhance spawning. 5.6.7.4 Inundation of the Wateree River floodplain will be enhanced through gradual reductions of operations at the end of high inflow events. 5.6.7.5 Critical Flows in the LIP and MEP will provide a level of aquatic habitat protection that has never existed before. 5.7 Wylie High Inflow Protocol 5.7.1 Interests Influencing the Wylie High Inflow Protocol -After the recommended preliminary aquatic flows below Wylie Hydro were combined with the recommended reservoir elevations, the recreation flows, the water user flows and the Low Inflow Protocol (LIP) stage triggers in the CHEOPSTM operations model, the operational scenario could not satisfy the four high priority criteria listed in Paragraph 5.1.3. Some trial runs lowered Mountain Island Lake elevations well below the Critical Reservoir Elevation and severely lowered Lake James; other scenarios caused the LIP to enter Stage 4 (a potentially unsustainable stage involving emergency water-use restrictions). Based on numerous alternative runs, the minimum continuous flows from the Wylie Development emerged as the dominant factor affecting scenario outcomes. 5.7.2 Studies - No additional studies were performed, but additional CHEOPSTm runs for various operational scenarios were completed and compared, along with checks on habitat gains or losses using the ITSA Spreadsheet. 5.7.3 Decision Process - It was clear to most but not all members of the Aquatics Resource Committee that the higher minimum continuous flows recommended for the spring at Wylie Dam could not be maintained during dry and drought conditions without leading to serious consequences to the reservoir system. After much discussion on both the flows and what conditions would trigger the High Inflow Protocol, the Committee concluded on the conditions in the proposed Wylie High Inflow Protocol License Article. 5.7.4 Alternatives Considered - The Aquatics Resource Committee considered several options to access more storage in North Carolina reservoirs, including eliminating the winter reservoir drawdowns, using the storage in the reservoirs in the near-term before the onset of additional growth in public water supply requirements, increasing the drawdown at Lake James, and additional high inflow protocols at Bridgewater and Oxford. None of these alternatives proved viable because they either resulted in excessive reservoir drawdowns, excessive hydro operational impacts, or were ineffectual. 5.7.5 Article and Provisions - The proposed New License Article defines the inflow conditions that would trigger the Wylie High Inflow Protocol and also the conditions determining its duration. 5.7.6 Conclusions - Implementation of the Wylie High Inflow Protocol enables the flows to approach the desired flows for habitat needs in many years when inflows are sufficient, but adequately preserves Project storage to reduce C-W Explanatory Statement (Rev 1) 12-22-06 19 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement the possibility of severe upstream consequences (LIP Stage 4) during drought conditions. 5.8 Flows Supporting Public Water Supply and Industrial Processes 5.8.1 Interests Influencing Flows for Public Water Supply - Stakeholders had general interests in assuring long-term water availability and quality for public water supply. The public water suppliers represented on the Stakeholder Teams, who in turn formed an advisory group of more than 35 public water suppliers, had more specific interests. Overall, they wanted to assure that their current and projected water needs would be given at least equal consideration to other likely license requirements (e.g., aquatic flows) and wished it to be generally recognized in the deliberations that the availability of Project waters for drinking water directly impacted more than 1.3 million people in the region. More specifically, they wanted to assure perpetual storage at or above the amounts needed to meet long-term demands (safe yield). They also focused on the process and procedures used by the Licensee and the FERC to approve adding or expanding water intakes on the Project. There are also several industries including a paper mill and a steam plant located on regulated river reaches that require certain minimum flows to meet their requirements. 5.8.2 Studies - The Water Supply Study projected water withdrawal requirements and flow returns for 50 years. These withdrawals and returns were used in the CHEOPSTM operations model to develop the preferred operations scenario (see Section 5.2). The Low Inflow Protocol Study provided a framework for the staged water use reductions during low inflow conditions. 5.8.3 Decision Process - Most of the detailed discussion and conclusions reached were with the Water Users Group (an Ad Hoc Committee), which included the Licensee, public water suppliers and the three regional Councils of Government. Not specifically related to relicensing, but being concurrently considered, was the Licensee's proposal to charge withdrawal fees, under the Commission's standard joint-use article. Although the Licensee's proposal would use the fee collections to reinvest in improving the system storage, the fee issue became one of the most broadly contentious issues in the relicensing process. The water suppliers offered a counter proposal that would create a voluntary group of users that pay dues to fund projects that would protect and enhance water quantity and quality. The proposal was acceptable to the stakeholders and the Licensee, and much of the remaining discussion focused on developing membership requirements, projects to be funded by the dues, dues amounts, and a dues collection schedule. The results are shown in Appendix N of the Comprehensive Relicensing Agreement. Two important provisions also appear in Appendix N: the Licensee will not charge withdrawal fees to members in good standing of the WMG for the term of the New License, and the Licensee will also pay dues to be a WMG member. Much of the remaining discussion centered on capturing the legal language of the fee issue (preserving everyone's rights), addressed procedures for obtaining permits and easements for expanded or new water withdrawal facilities, and the future use of models and studies developed during relicensing.

The Comprehensive Relicensing Agreement captures the provisions related to easements and permits, use of studies and models, and water withdrawal fees. 5.8.6 Conclusions - Below are some of the important measures in the Agreement. 5.8.6.1 Operations under the New License and the LIP drought response plans are based on the most extensive assessment of current and future water demands ever completed in the Basin. 5.8.6.2 Public water supply needs were projected to Year 2058, and these projections were incorporated into the operational scenarios analyzed by the CHEOPSTM model. 5.8.6.3 The Licensee will maintain the CHEOPSTM model, including updates in water withdrawals and other input parameters, for use by the Licensee, water withdrawers, and state agencies in considering future withdrawal requests. 5.8.6.4 The Licensee will make the comprehensive, basin-wide water supply study available for use by water suppliers and state agencies for evaluations of future water withdrawal requirements. 5.8.6.5 The LIP provides a drought response that coordinates actions by the Licensee and the public water supply systems over the Basin, extending the point at which water demands exceed safe yields of some reservoirs by a decade or more. 5.8.6.6 A Water Management Group (WMG) of public water suppliers and the Licensee will form in 2007 to identify and fund projects to improve the capability of the reservoir system to provide public water supply, industrial and irrigation water, cooling for larger power plants and enhanced water quality. 5.8.6.7 Normal Minimum Elevations, which among other things improve the management of storage, will be in the License for the first time. 5.8.6.8 The Low Inflow Protocol defines a set of progressive staged procedures implemented to preserve water supplies and endure even the more severe droughts like the one in 1998-2002. 5.8.6.9 Critical Reservoir Elevations and Critical Flows are established based on relicensing studies and included in the Low Inflow Protocol and the Maintenance and Emergency Protocol. C-W Explanatory Statement (Rev 1) 12-22-06 21 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 5.9 Low Inflow Protocol 5.9.1 Interests Influencing the Low Inflow Protocol (LIP) - Managing the available water supply and drought management were the most requested study topics received in the Catawba-Wateree relicensing process. 5.9.2 Studies - The Low Inflow Protocol Study (Operations 05) developed a LIP. The first drafts were developed by a group that included the Licensee, public water suppliers, and state agencies. The LIP became an element of the operations scenario development (refer to Section 5.2). 5.9.3 Decision Process - The basic staged structure of the initial LIP drafts changed little throughout the development of the preferred operations scenario. However, the water quantity demands on the system required earlier and more aggressive reductions in water use in the LIP than was initially anticipated. Because discretionary hydro generation stops during LIP Stage 0, the modeling calculated discretionary hydro generation would be lost 39 percent of the time during the next 50 years. 5.9.4 Alternatives Discussed - No alternatives to implementing an LIP were discussed. The actual protocol did, however, undergo the intensive scrutiny of water users and was validated via CHEOPSTM modeling. Numerous iterations of stage triggers, corresponding flow reductions and Critical Flows were necessary in conjunction with iterations in flow releases and reservoir levels to achieve the sustainable balance and benefits of this Agreement. 5.9.5 Article and Provisions - Because the LIP was filed with the License Application, the article anticipates Commission approval of the LIP and inclusion in the New License. The article also anticipates improvements to the LIP when it is used. The Agreement calls for the Drought Management Advisory Group (DMAG) to periodically assess whether improvements are warranted and for the Licensee to submit to the Commission for approval any major LIP improvements to which the DMAG agrees by consensus. 5.9.6 Conclusions - It became evident during the relicensing process that this protocol is absolutely necessary to meet the escalating basin water and power needs and protect and enhance environmental resources through low water conditions. The LIP requires basin-wide coordinated reductions in water use during droughts, and it is this coordination that will allow the Project to sustain the expected growth in water demand. 5.10 Maintenance and Emergency Protocol 5.10.1 Interests Influencing the Maintenance and Emergency Protocol (MEP) - Stakeholders were interested in establishing notification, consultation, communications, and mitigation approaches to use during times when the Project is required to be operated abnormally resulting either from a planned condition (e.g., maintenance) or an unplanned condition (e.g., dam safety, high water, or power grid emergencies). 5.10.2 Studies - Other than the effort to prepare the MEP, no studies specifically related to the MEP were conducted. However, the knowledge from the IFIM studies used to relate flows in the regulated river reaches to aquatic habitat was considered informally in assessing the mitigation suggestions. C-W Explanatory Statement (Rev 1) 12-22-06 22 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 5.10.3 Decision Process - The Licensee identified the most likely abnormal conditions (in addition to low inflows, which are addressed in the Low Inflow Protocol) and proposed the mitigation actions and communications that the Licensee would take during abnormal periods through its Maintenance and Emergency Protocol. Some conditions were added from the Licensee's initial proposal, and the discussions centered on who would be notified and how mitigation could be improved to minimize the impacts of abnormal operations. 5.10.4 Alternatives Discussed - No significant alternatives were discussed other than as indicated in the above Paragraph. 5.10.5 Articles and Provisions - Because the MEP was filed with the License Application, the article anticipates Commission approval of the MEP and inclusion in the New License. The article also provides that the MEP be evaluated after each use to assess whether improvements are warranted and whether to submit a revision to the Commission for approval. 5.10.6 Conclusions - The MEP will establish approaches that can be anticipated and understood during abnormal operating conditions. 6.0 Water Quality Articles and Agreements 6.1 The following proposed License Articles address the Licensee's water quality improvement and monitoring requirements. 6.1.1 ARTICLE - Water Quality Monitoring Plan 6.1.2 ARTICLE - Flow and Water Quality Implementation Plan 6.2 Interests Affecting Water Quality - All stakeholders acknowledge the Licensee's responsibility to meet state water quality standards that are related to Project operations. These standards are primarily temperature and dissolved oxygen (DO) in hydro station flow releases. 6.3 Studies - The Licensee combined years of historical water quality monitoring records with supplemental water quality sampling conducted in 2004 to develop extensive and highly calibrated hydrodynamic and water quality computer models of the tailrace and the downstream riverine systems (River Management System) and reservoirs (CE-QUAL-W2). These models were used individually and collectively to characterize the downstream temperatures and dissolved oxygen concentrations (and transport of other water quality constituents) under a variety of Project operations, which is beyond the capability of empirical data collection. The models were used to establish the extent of Project influence and non-point (nutrient) influence on downstream water quality, to evaluate feasible alternative operating or engineering scenarios, and to test the water quality implications of certain aquatic in-stream flow proposals and low-inflow situations. 6.4 Decision Process - Neither the Agreement nor the License Application finalizes the terms of the North Carolina or South Carolina Section 401 Water Quality Certifications. Rather, the focus of the Agreement and proposed License Articles is to develop stakeholder recommendations to be submitted during both states' water quality certification processes. 6.5 Alternatives Considered - There are no alternatives to securing the required water quality certifications other than a waiver by the applicable state agency of the requirement to get a water quality certification. Water Quality Resource Committee C-W Explanatory Statement (Rev 1) 12-22-06 23 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement members reviewed model results of various operational scenarios and concluded that primary hydro project impacts on water quality would be relatively unaffected under the various operating scenarios. Nutrient concentrations, while not a hydro project operational impact, were shown not to respond significantly to the spectrum of operating scenarios ranging from current operations to run-of-river operations. Water Quality Resource Committee members developed a "good faith" list of potential flow and water quality improvement modifications, but acknowledge that the governing process and final decision will be rendered by each state's water quality agency. 6.6 The Article's Structure - Based on consultation, stakeholders will recommend a Flow and Water Quality Implementation Plan (FWQIP) that includes station modifications for dissolved oxygen compliance; implementation schedules; mitigation plans and monitoring plans to be considered in each state's water quality certification process. The FWQIP will include interim flow measures to implement between issuance of the New License and completion of equipment modifications. At several locations, the water quality equipment modification is also the means to deliver minimum continuous flows. 6.7 Conclusions - After these recommendations have been modified and/or accepted in approved water quality certifications, they will be included in the implementation plan that will be filed with the FERC after issuance of the New License. In addition to operating existing DO-enhancing equipment, the Licensee will replace hydro runners with new aerating runners at the Bridgewater, Rhodhiss, Oxford, Wylie, and Wateree developments to provide minimum continuous flows and increased dissolved oxygen; make modifications at the Great Falls diversion dams to provide flows into the Great Falls Bypassed Reaches; and add aerating flow valves at the Oxford Development and Catawba Dam to provide minimum continuous flows and improved dissolved oxygen. 7.0 Gaging and Monitoring Articles and Agreements 7.1 The following two proposed License Articles address the Licensee's gaging and monitoring requirements. 7.1.1 ARTICLE - Flow and Reservoir Elevation Monitoring 7.1.2 ARTICLE - Funding for USGS Streamflow Gages 7.2 Interests Influencing Gaging and Monitoring - Compliance monitoring and reporting will be required to validate the Licensee's compliance with flow release, water quality and reservoir level requirements of the New License and 401 Water Quality Certifications. 7.3 Studies - Data collected in 2004 and modeling were used to determine the downstream extent of dissolved oxygen enhancements. Also the Water Quality Resource Committee discussed the continued accuracy of current water quality monitor locations given recent station modifications (buttresses) for flood stability. 7.4 Decision Process - Stakeholders used study findings coupled with site-by-site assessments of viable and accurate water quality monitor locations to develop a Water Quality Monitoring Plan. 7.5 Alternatives Considered - None. 7.6 The Articles' Structure - The Water Quality Monitoring Plan requires the Licensee to monitor minimum continuous flows and recreation flows at applicable C-W Explanatory Statement (Rev 1) 12-22-06 24 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement developments, dissolved oxygen and temperatures at all developments, and reservoir levels at all developments. By June 30 of each year, the Licensee will submit monitoring results in an Annual Report for the previous full calendar year. In addition to compliance-related monitoring and reporting, non-compliance-related requirements include providing monthly interim water quality data summaries to each state water quality agency from April through November of each year, supplemental trout habitat monitoring below Bridgewater Hydro and water quality trend monitoring in major tributaries that enter the Project in both North Carolina and South Carolina. 7.7 Conclusions - As with the FWQIP, stakeholders will recommend the Water Quality Monitoring Plan to be considered in each state's water quality certification process. After these recommendations have been modified and/or accepted in an approved water quality certification, they will be included in the implementation plan that will be filed with the FERC after issuance of the New License. 8.0 Species Protection Article and Agreements 8.1 The following proposed License Article addresses the Licensee's Species Protection Plans. 8.1.1 ARTICLE - Federal Threatened and Endangered Species Protection Plans 8.2 Interests Affecting Species Protection - There was considerable general stakeholder interest in protecting Rare, Threatened and Endangered (RTE) species, but specific interests in the species and their locations were mostly represented by the federal and state resource agencies. There was one exception: a South Carolina-listed species, the Rocky Shoals spiderlily, received considerable general interest because of its beautiful spring flowers, its location in the river at the Landsford Canal State (SC) Park, and its rarity in the southeast. These spiderlilies are an important public attraction during their spring flowering period. 8.3 Studies - Several studies evaluated the potential for the occurrence of rare, threatened or endangered plant, aquatic or wildlife species in the Project area as well as the potential Project impacts. These studies included Fish Community Assessment (Aquatics 01); Diadromous Fish Studies (Aquatics 03); Mussel Survey (Aquatics 06); M acroi nverteb rate Surveys of the Catawba-Wateree Hydroelectric Facilities (Aquatics 07); Macro-Snail Surveys for Catawba-Wateree Relicensing (Aquatics 07); Crayfish Surveys for Catawba-Wateree Relicensing (Aquatics 07); Botanical Study of the Great Falls Bypassed Reaches of the Catawba River (Terrestrial 03); Rare, Threatened, and Endangered Amphibians and Reptiles within the Catawba-Wateree System (Terrestrial 04); Rare, Threatened, and Endangered (RTE) Mammals of the Catawba-Wateree Project Area in North and South Carolina (Terrestrial 04); A Biological Survey For Breeding, Migratory, Wintering, and Resident Avian Species Associated with the Catawba-Wateree Relicensing Project Area in North Carolina and South Carolina (Terrestrial 05); Herpetological Inventory of the Great Falls Bypassed Reaches, South Carolina (Terrestrial 06); and, The Mammals of the Great Falls Bypassed Reaches (Great Falls-Dearborn Development) in South Carolina (Terrestrial 06). 8.4 Decision Process - Most of the Terrestrial Resource Committee's efforts focused on identifying the RTE species for the Project area, establishing procedures for maintaining the RTE lists for the most current information, and establishing some approaches for dealing with the RTEs that would be further detailed in the actual C-W Explanatory Statement (Rev 1) 12-22-06 25 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement Species Protection Plans (SPPs). The structure of the SPPs was also established. The SPPs for each state- and federal-listed species were prepared during the relicensing process and were commented on by stakeholders and appropriate other agencies that were not Stakeholder Team Members. The SPPs for federally listed species are filed with the License Application. In establishing the minimum flows in the proposed Minimum Flows License Article, the Aquatics Resource Committee considered a habitat suitability curve for the Rocky Shoals spiderlily to evaluate flow impacts on the plants in the same way as it did for various aquatic species. Although the USFWS and NOAA Fisheries were invited to be participants in the Stakeholder Teams, neither chose to participate as Team Members. However, USFWS representatives remained active in the relicensing as interested parties and were active on the Aquatics and other Resource Committees. The relicensing process did not conclude with an agreement on a fish passage prescription or a reservation of authority. After much discussion about protecting the negotiated gains in other resource areas in case there is a future fish passage prescription, the Licensee agreed that construction costs and operation and maintenance costs related to facilities to implement any future fish passage prescription would not affect other aspects of the Comprehensive Relicensing Agreement. However, if any agency prescribed different flows, the Agreement includes provisions for dealing with this inconsistency with the Agreement. 8.5 Alternatives Considered - Other than alternatives discussed in relation to the minimum flows for aquatic communities (see Paragraph 5.17), there were no significant alternatives considered that were not addressed in the proposed License Articles or in the provisions. 8.6 Article Structure - Because the SPPs for federally listed species were filed with the License Application, the proposed License Article anticipates Commission approval of the Plans and inclusion in the New License. The proposed License Article also requires maintaining the federal RTE list for the Project in accordance with the protocol established by the stakeholders. Although not in the proposed License Article, the Agreement outlines a similar approach for maintaining the list for NC- and SC-listed species. 8.7 Conclusions - In addition to the SPP and the protocols for maintaining the lists, important measures in the SPP and the Agreement include: 8.7.1 The Licensee will collect bald eagle information (e.g., new nest sites, existing status, recruitment estimates) related to the Project area after five years and then every three years for the term of the New License. 8.7.2 The Licensee will form a partnership with SCDPRT to jointly develop and implement a monitoring plan for the spiderlilies at Landsford Canal State Park. 9.0 Public Information Article and Agreements 9.1 The following proposed License Article addresses the Licensee's public information requirements. 9.1.1 ARTICLE - Public Information 9.2 Interests Influencing Public Information - Stakeholders' interests in public information can be grouped into three general categories: (i) Information to advise the public about the Project's recreational opportunities; (ii) information to enhance the C-W Explanatory Statement (Rev 1) 12-22-06 26 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement public's use of these recreation resources such as appropriate signage and interpretive information about Project-area cultural and historic resources; and (iii) public safety information (including warnings) related to use of the Project's recreational resources. 9.3 Studies - Because of the widespread interests and both general and local stakeholder knowledge related to public information needs, the Stakeholder Teams did not create an Ad Hoc Committee to address public information. Instead, the four regional Advisory Groups addressed the needs and spent considerable time discussing possible improvements. Except for the Recreation Flow Communications Study, the Stakeholder Team discussions provided the information that may have otherwise been provided by a study. 9.4 Decision Process - The stakeholders addressed both the general needs (e.g., what information might apply to all access areas) and specific needs (e.g., warning sirens at Riverbend Park). The results are combined in the proposed New License Article and the provisions in Section 8.0 of the Comprehensive Relicensing Agreement. 9.5 Alternatives Considered - The topic receiving the most attention was whether and how to address non-English-speaking recreation users; notably Spanish speakers. Some wanted all signage to include Spanish; others thought it was not needed. The conclusion, captured in the provisions, was to include (i) English and universal symbols at all access areas; (ii) warning signs at all the developments' tailraces in both English and Spanish because no appropriate universal symbols exist for warning of potential rising water in the tailraces; and (iii) a review of the demographic needs of recreation users with local governments, state demographers, and marine commissions at ten-year or less intervals. 9.6 Article and Provisions - The proposed New License Article identifies the information to appear on the Licensee's Web site and includes detailed information about reservoir levels and recreational flows that are prescribed in other proposed New License Articles. Not included in the Article is information that will appear in the Licensee's Public Safety Plans or Recreation Management Plan filed with the Commission. The provisions cover several additional details, such as completing a communication technology review and maintaining the list of Parties to the Agreement. 9.7 Conclusions - Information regarding reservoir level ranges, water release times, generation schedules, and maps to public access areas will be provided. River paddlers and anglers will have access to information on releases from dams. Information posted on signs will be provided in English and universal symbols with signage also in Spanish at the tailraces. A map of historic canoe trails in South Carolina will also be developed. 10.0 Recreation Articles and Agreements 10.1 The following two proposed License Articles address Project recreation facilities and future planning for the Project-related recreation needs of the area. 10.1.1 ARTICLE - Recreation Management Plan 10.1.2 ARTICLE - Recreation Planning 10.2 Interests Affecting Recreation - The adequacy of current recreational facilities at the Project, new recreational interests, and anticipating future recreational needs via land protection were prevalent interests during the relicensing process. The stakeholders also had strong interest in adding swimming beaches, trails, and additional C-W Explanatory Statement (Rev 1) 12-22-06 27 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement facilities for recreation on the regulated river reaches. In addition the stakeholders identified many specific facility needs throughout the Basin. 10.3 Studies - The Recreation Use and Needs (RUN) Study developed and used ground and mail surveys and updated population projections to predict current and future recreation needs. The Stakeholder Teams and Recreation Ad Hoc Committee (AHC) included a number of city and county planners and councils of government. Although the RUN Study identified needs for very specific locations, it (along with non- relicensing studies) also pointed to the following general areas: 10.3.1 The Licensee has had in place for a number of years an Access Area Improvement Initiative (AAII). The AAII is a program in which the Licensee offers to lease access areas to state agencies, local counties, municipalities and commercial operators. The lessee then has the opportunity to add facilities and amenities that address the local recreation needs. During the relicensing process, the Licensee convened representatives from the region's cities, towns, counties and councils of government to review and revise the AAII lease program. The AAII was modified to be more appealing to the local governments. The most significant change was to lengthen the term of the lease to better justify investments into the facilities. 10.3.2 The Licensee's focus on providing access to the reservoirs for motorized boating has been in place for many years. While there were some isolated recommendations to improve facilities supporting motorized boating, much of the data indicated a need to focus future recreational facility development on non-motorized boating and land-based recreation. 10.4 Decision Process - The Recreation AHC developed a table of potential recreation amenities and prioritized them. The Licensee then used the AHC-prioritized list and made a proposal for recreation amenities the Licensee could develop, either alone or in partnership through the AAII. The AHC completed several iterations of this process and formulated a recommendation for the Stakeholder Teams that identified a 20-year recreation amenities plan which it then further discussed and modified. 10.5 Alternatives Considered - Many different types of facilities and activities at different locations were evaluated by the Recreation AHC. 10.6 Structure of the Articles and the Recreation Management Plan - The Agreement identifies a Recreation Management Plan (RMP) that addresses recreation needs for the first 20 years of the New License. Components of the RMP are included in both the proposed recreation license articles and the resource provisions. 10.6.1 RMP Measures - The proposed RMP License Article lists the recreation measures that the Licensee would complete within 20 years following FERC's approval of the RMP. The RMP will include these measures, along with the additional detail required by the proposed RMP License Article, for development in five-year increments. The RMP measures in each increment are listed in the Section 10.0 of the Agreement along with recreation measures that are not proposed to be governed by the New License - typically those measures that will be owned by other entities and/or have little or no nexus to the Project. In the 20 years, the measures are front-end loaded: approximately 61 percent (by the Licensee's implementation dollars) will occur in the first five- year period; 29 percent in the second, 6 percent in the third, and 4 percent in the fourth five-year period. C-W Explanatory Statement (Rev 1) 12-22-06 28 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 10.6.2 Future Recreation Planning - The proposed Recreation Planning License Article identifies the timeframes (first 20 years and then every 10 years thereafter) for the next thorough reviews of the of the Project-related recreation use and needs leading to filing a RMP supplement with the Commission. It also identifies the public involvement required in the development of the supplement: the agencies, local governments and other interested parties. While the Recreation AHC and the stakeholders are confident of their 20-year planning, they nevertheless recognized that uses and needs may change over that period and therefore incorporated into the Agreement two intermediate reviews - at 7 years and 14 years - to consider both changes to the 20-year plan and/or some limited additions (up to $2 million for each seven-year period). Neither intermediate review will include a comprehensive RUN Study, but would use the FERC Form 80 conclusions and any information available from the recreation departments in the state and local governments as their input. Any changes within the Project Boundaries recommended in these interim reviews will be filed with Commission in a supplement or revision to the RMP. 10.7 Conclusions - Below are some of the important public recreation measures in the Agreement. 10.7.1 A full 20-year Recreation Management Plan will be submitted within one year following the issuance of the New License; 10.7.2 A Planning Team of stakeholders will review the recreation uses and needs at 7 and 14 years and agree on any adjustments that the Licensee will submit to the FERC. 10.7.3 The Licensee will develop or partner with others to develop enhancements to existing public recreation facilities or construction of new facilities at 88 locations. • Restrooms will be added at 28 sites; • Swimming areas will be added at 10 sites; • New fishing piers will be added to 13 sites; Canoe/Kayak launches will be added at 16 sites; • 5 courtesy docks will be constructed; • Parking will be added, expanded, or improved at 33 sites; • Picnicking will be added or improved at 21 sites; Portage trails will be added or improved at 8 sites; Approximately 270 acres of property will be set aside for new Licensee- owned access areas or expansions of the approximate 2,000 acres total of existing Licensee-owned access areas; Ownership of approximately 2,100 acres will be transferred to the States for permanent conservation and public recreation; and • Approximately 3,400 acres will be offered to the States at discounted prices for permanent conservation and public recreation. C-W Explanatory Statement (Rev 1) 12-22-06 29 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 11.o Shoreline Management Plan Articles and Agreements 11.1 The following two proposed License Articles address the Licensee's Shoreline Management Plan (SMP). 11.1.1 ARTICLE - Shoreline Management Plan 11.1.2 ARTICLE - Shoreline Management Plan Review and Update Procedures 11.2 Interests Affecting Shoreline Management - The major interest related to the Licensee's shoreline management was to balance habitat, water quality and natural aspects of the reservoirs with development. The interest, in effect, translated into determining the role (if any) the Licensee's Shoreline Management Plan should have in limiting development and to provide widespread buffers around the lakes. Although controlling development on properties outside the Project Boundaries is the responsibility of the local governments' zoning and land conservation, to many stakeholders, these tools alone have not met their interests. A closely related interest for many stakeholders was to toughen the SMP's Shoreline Management Guidelines to increase the identification and protection of environmentally sensitive and prime aquatic and near-shore habitat. One particular issue was to eliminate what came to be known as "double counting" - permitting one marina slip AND one private dock for each 100-ft of developable shoreline. 11.3 Studies - There were four main elements from the studies that went into the preparation of the Shoreline Management Plan Maps, Lake Use Restrictions, and Shoreline Management Guidelines: 15 11.3.1 High-resolution digital orthophotography that provided detailed photographs of the entire shoreline of the Project; 11.3.2 Aerial Light Detection and Ranging (LiDar) technology that provided digital elevations and planimetric mapping of the entire shoreline of the Project; 11.3.3 Estimates of the end effects on boat carrying capacity on each reservoir for four different assumed future build-out scenarios; and 11.3.4 Meetings with stakeholders during the relicensing to complete a comprehensive review and revision of the existing Shoreline Management Guidelines. 11.4 Decision Processes 11.4.1 Shoreline Mapping, Classifications, and Lake Use Restrictions -A monumental level of effort was applied to review all the aerial photographs for the entire 1,795 miles of shoreline (including islands) and confirm or revise the classifications. The effort consumed seven hours a day, three days a week, for three months and was completed mostly by the Licensee's Lake Services personnel, with occasional oversight by members of the Shoreline Management Resource Committee (RC). Most of the classifications were straight forward, but about 10 types of complicated shoreline areas were reviewed by the full RC to establish protocols for the continued revisions. In one instance, the protocol led 15 Shoreline Management Plan Mapping Study Team Report (SMP01), April 2005; Shoreline Management Plan Shoreline Management Guidelines Study (SMP02) Report, May 2005. The Lake Use Restrictions and Shoreline Management Guidelines appear in Appendix J of the Comprehensive Relicensing Agreement. C-W Explanatory Statement (Rev 1) 12-22-06 30 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement to an additional restricted-use classification: the Natural Isolated Berm. The RC also received periodic updates as did the full Stakeholder Teams. After much discussion in the RC, the future-use SMP classifications were based on the characteristics of the shoreline within the Project Boundaries and not on upland zoning or the desire to control the lands outside the Project Boundaries. 11.4.2 Shoreline Management Guidelines - A small, dedicated group of stakeholders from the Shoreline Management RC met regularly during 2005 and 2006 to review and revise the guidelines from front to back. Addressing the balance between development and environmental interests, the Committee recommended a more restricted set of guidelines and added two new restricted classifications: the Natural Isolated Berm and the Bottomland Hardwood Area. The Shoreline Management Guidelines document nearly doubled in size compared to the previous version. 11.5 Alternatives Discussed - Each complicated shoreline area type received considerable discussion to establish its classification protocol. During the long process of updating the SMGs, numerous alternatives were considered and negotiated. There was a strong interest to control development outside the Project Boundaries, but the end result was additional guidelines for increased protection of environmentally sensitive areas within the Project Boundaries. Some of the results are shown in the Conclusions Paragraph below. One of the most contentious proposals was to require buffers outside the Project Boundaries as a condition of receiving a dock permit. This was not agreed to; however, the Committee instead developed an incentive program for developers to preserve shoreline and also to leave undeveloped land upland and adjacent to restricted shoreline. Another approach addressing development was to draft a memorandum-of- understanding (MOU) template that would improve the coordination between Licensee and local governments and the States in four areas: (i) data sharing, (ii) coordination for enforcement of buffer regulations, (iii) coordination of permitting review, and (iv) agreement that the SMP classifications do not supersede government's authority to control lands outside the Project Boundaries. 11.6 Articles and Provisions - Because the SMP, including the Shoreline Classifications, Lake Use Restrictions, and Shoreline Management Guidelines, was filed with the License Application, the proposed New License Article anticipates Commission approval of the SMP. The article also anticipates modifications to the SMP. The provisions add the formation of a stakeholder workgroup to discuss SMP implementation and its effectiveness in protecting near-shore habitat. 11.7 Conclusions - The Agreement adds considerably to the environmental protection measures and partially accommodates the interests for controlling development outside the Project Boundaries while still allowing for substantial new reservoir uses. A full summary of the important changes is provided in the Study Report. Some of the more significant changes are listed below: 11.7.1 Two new restricted shoreline classifications; 11.7.2 Removed "double counting" for shoreline length requirements for docks and marina slips; 11.7.3 New water willow protection; 11.7.4 Limits on marinas in narrow coves; C-W Explanatory Statement (Rev 1) 12-22-06 31 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 11.7.5 Increased minimum developable shoreline length requirements for docks from 75 feet to 100 feet; 11.7.6 Criterion to encourage shallow-water fish attractors; 11.7.7 Requirements for new or modified water intakes to protect and increase Total Usable Storage; 11.7.8 A developer incentive program to preserve undeveloped shoreline and conservation areas abutting shoreline with environmentally restricted classifications; 11.7.9 Improved protection of wetlands and cultural and historic sites; and 11.7.10 A MOU template for the Licensee and governmental entities that oversee lands abutting the Project Boundaries to better coordinate the responsibilities in four areas: 11.7.10.1 Data sharing; 11.7.10.2 Improved coordination with the Licensee for enforcement of buffer regulations; 11.7.10.3 Better coordination of permitting reviews (required from both the Licensee and the governmental entity); and 11.7.10.4 Agreements that SMP classifications do not supersede local government plans or authority related to land use. 12.0 Cultural Resources Article and Agreements 12.1 The following proposed New License Article addresses the Licensee's Historic Properties Management Plan. 12.1.1 ARTICLE - Historic Properties 12.2 Interests Affecting Historic Properties - There was considerable general stakeholder interest in both protecting cultural resources and in providing communications and education programs about cultural resources. There was also a focused interest in preserving and/or protecting several well-known sites in the area - notably Dearborn Island, site of a Jefferson-era armory, and the Mulberry Mound, a pre- contact Native American site located on private property adjoining the Wateree Regulated River Reach. Some stakeholders also believed that the Licensee should mitigate for cultural resources inundated when the Project developments were constructed, most notably the Overmountain Victory National Historic Trail in the Lake James area. The State Historic Preservation Offices (SHPO) from both NC and SC and the Catawba Indian Nation Tribal Historic Preservation Office (THPO) focused their attention primarily on complying with Section 106 of the National Historic Preservation Act and ensuring protection for Historic Properties (HPs), those sites eligible or potentially eligible for inclusion in the National Register of Historic Places. 12.3 Studies - During the relicensing process, the Licensee conducted archaeological surveys of approximately 1,900 acres of islands within the Project reservoirs, assessed Project Structures to determine which are Historic Properties, and evaluated the effects of Project operations on the Mulberry site located downstream of Wateree Dam. The studies identified locations of HPs and assessed current or potential future Project effects. The findings are detailed in the relicensing studies. C-W Explanatory Statement (Rev 1) 12-22-06 32 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 12.4 Decision Process - The Licensee worked closely with representatives of the Cultural Resources Resource Committee (CRRC) on all aspects of cultural resources management associated with the relicensing effort. Recognizing that some of the stakeholders' interests were not clearly within the scope of the Section 106 process, the CRRC worked to identify activities that would ensure compliance with Section 106 while also meeting the interests of relicensing process participants. 12.5 Alternatives Considered - Section 106 requires that a Historic Properties Management Plan (HPMP) be developed. The CRRC focused its discussions on the appropriate management strategies for known HPs within the Project Boundaries and the Project's Area of Potential Effects and whether it was more appropriate to direct resources towards management of HPs within the Project Boundaries or whether providing mitigation at other sites provided a greater benefit. Much debate focused on the appropriate management considerations for the Mulberry site given the lack of a proven Project effect on the site as evidenced by the Licensee's evaluation of Project effects. However, by reallocating resources that would have been directed to management of less significant HPs within the FERC Project Boundaries to activities at the Mulberry site, the Agreement not only mitigates for Project effects on HPs within the FERC Project Boundaries, but also meets a significant stakeholder interest. 12.6 The Article Structure - The Article anticipates that, because the HPMP has been accepted by the Catawba Indian Nation THPO and the North Carolina and South Carolina SHPOs and was filed with the License Application, the FERC will approve the HPMP and order the Licensee to implement it. The Article also anticipates that the FERC will develop and enter into a Programmatic Agreement with the North Carolina and South Carolina SHPOs and the Catawba Indian Nation THPO as is required by Section 106. 12.7 Conclusions - The HPMP addresses management of Historic Properties in accordance with Section 106 of the NHPA. Activities stipulated in the HPMP include: 12.7.1 Management of historic hydroelectric structures; 12.7.2 Monitoring of known HPs; 12.7.3 The consideration and protection of HPs in conjunction with the implementation of the Shoreline Management Plan; and 12.7.4 Site-specific management plans for a number of Historic Properties. 13.0 Other Resource Agreements 13.1 Interests Influencing Other Resource Enhancements 13.1.1 Land Conservation - When the Licensee and its predecessor companies began developing the hydro facilities, they purchased tremendous amounts of land. Much of the land was ultimately inundated, but much of it also became lakefront property. For many years, these lands remained undeveloped and much of it was leased at nominal costs to state wildlife agencies for wildlife management areas. The lands came to be seen as public lands even though the property was owned by an investor-owned corporation. As property became more valuable, it was sold to private developers and leased at higher cost to private entities. This history colored the relicensing discussion, and some stakeholders had expectations that large amounts of land (perhaps 50,000 acres or more) would be conserved in the process. Land preservation and C-W Explanatory Statement (Rev 1) 12-22-06 33 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement development control became central interests influencing the direction of the negotiations. 13.1.2 Invasive Weed Management - Many stakeholders had direct experience with the impacts of invasive weeds in the reservoirs. And while generally recognizing the difficulties in managing them, they wanted the Licensee and the state agencies to continue their invasive weed management programs. 13.1.3 Trash Management - Stakeholders were interested in reducing the trash and floating debris in the reservoirs and river reaches and ensuring proper disposal. 13.1.4 Flood Management - Stakeholders and particularly residents around Lake Wateree had a strong interest in reducing the incidences of flooding. 13.2 Studies 13.2.1 Land Conservation - The Land Ad Hoc Committee was formed to oversee the creation of a GIS Database with all the land parcels that had been identified by a variety of means during the relicensing. The database, which included desired land attributes, along with stakeholder priority weightings, helped focus the wide-ranging land conservation interests. 13.2.2 Invasive Weed Management - There were no specific studies, but the Reservoir Level Study (Ops 02) provided some context because one management strategy is to drawdown the reservoirs when there is a possibility that cold temperatures could kill the weeds. 13.2.3 Trash Management - A trash management plan (Ops 03) was developed using operations experience. An important recognition was that Fishing Creek Hydro was a significant trash accumulation point. 13.2.4 Flood Management - The Wateree High Water Level Study (Ops 08) reviewed Lake Wateree's historic reservoir levels and evaluated the effectiveness of several alternative approaches to reduce the incidences and severity of flooding. One conclusion was that varying hydro system operations would only have minimal improvements in flood management at Lake Wateree. 13.3 Decision Processes 13.3.1 Land Conservation - With the information from the Land Database, and through many long discussions, several strategies emerged. A strategy for preserving lands was to provide significant funding to NC and SC state agencies to purchase land of their choice but with certain agreed-to preservation criteria. A second strategy was to add funding to the existing Habitat Enhancement Program (HEP) for preserving habitat in each state. Other strategies included direct conveyance (at no cost) of selected properties to state agencies, bargain sales of certain properties to public entities, and establishing conservation easements on some properties. 13.3.2 Trash Management - The trash management plan was reviewed and adjusted by the stakeholders and agreements were reached on the schedule for installing a new trash rake at Fishing Creek Hydro by December 31, 2007. Appropriate disposal approaches were discussed and agreed to. C-W Explanatory Statement (Rev 1) 12-22-06 34 Catawba-Wateree Project (FERC No. 2232) Comprehensive Relicensing Agreement- Explanatory Statement 13.3.3 Invasive Weed Management - Led by the state agencies, the discussion concluded with an agreement for the Licensee to continue funding these programs at existing funding levels and continue partnerships on the programs with the state agencies. 13.3.4 Flood Management - For the stakeholders representing Lake Wateree residents, this was a difficult issue. Residents wanted large flood management modifications to Wateree Dam with capability to pass 40,000 cfs or more. Other stakeholders regarded the potential cost of this alternative as out of balance with enhancements of other resources for the Basin, all competing for the same funding resources. After much discussion, a compromise was reached to install the still-expensive 10,000 cfs bladder dam alternative, but only if the New License term was for 50 years, which many stakeholders viewed as possible. 13.4 Provisions - All of the provisions were captured in Section 14.0 of the Comprehensive Relicensing Agreement. No article was proposed for these other resource enhancements. The specific land conservation funds or HEP enhancements were not in proposed License Articles because of the limited nexus to Project effects. No license article was proposed for the trash rake addition because it will be completed, with Commission approval, under the Existing License. The agreement to partner for invasive weed management will continue and allow the flexibility to adjust the program year-by-year and reservoir-by-reservoir as appropriate to the situation at the time. The flood management agreements are not proposed for a License Article at this time, but provided the New License term is 50 years and the other requirements noted in the Agreement are met, the Licensee will request FERC approval in the future to install the agreed-upon improvements. 13.5 Conclusions 13.5.1 Land Conservation and Habitat Improvement - The Licensee will provide $1 million to each States' HEP to support, protect, and enhance fish and wildlife habitat. The Licensee will contribute $5.32 to $6.82 million to SC state agencies and $4 to $5.5 million to NC state agencies (depending on the term of the New License) for additional land conservation. In all, more than 2,500 acres of property owned by Crescent Resources (part of Duke Energy) will be dedicated for public recreation and Crescent will offer state and local governments more than 3,400 additional acres at reduced prices. 13.5.2 Invasive Weed Management - The Licensee will continue to fund its aquatic weed management program in partnership with state agencies at recent levels plus escalation. 13.5.3 Trash Management - The Licensee will financially support annual clean-ups and will improve its trash management and disposal for trash found in the reservoirs and streams. 13.5.4 Flood Management - Wateree Dam modifications totaling approximately $6 million will be made to install a bladder dam provided several requirements are met including a 50-year New License term.
