2.0 General Project Description
2.1 Project Overview
Yadlnn-Pee Dee River Hydroelectric Project
Progress Energy's Yadkin-Pee Dee River Project (Project) is located on the Yadkin-Pee Dee River
in the State ofNorth Carolina and consists ofthe upstream 84 megawatt (MW) Tillery Development
and the downstream 24.6 MW Blewett Falls Development. Each development consists of a dam,
powerhouse, impoundment, substation, structures used in connection with the Project, water rights,
rights-of--way (ROW), lands, and interest in lands necessary for the operation and maintenance ofthe
Project.
The Blewett Falls and Tillery developments were constructed in the early 1900s. Blewett Falls was
placed in operation in 1912, and the Tillery Development commenced operations in 1928. The
primary purpose of the Project is to generate electricity and meet other important electrical system
needs for the benefit of Progress Energy's ratepayers. The Project is used for critical load-following
and on-peak generation and its economic viability is dependent on serving these specific purposes.
Both Tillery and Blewett Falls also have the capability to "black start", meaningthe ability to come
online under system blackout conditions to support local loads and aid in overall control arearestart
and recovery.
The Project has provided valuable service as a peaking and load-following electrical generation
resource throughout its entire history. From the period 1984 to 2003, the Project generated an
average annual output of 326 million kilowatt-hours (kWh) of renewable energy, while providing
significant recreational opportunities, supporting healthy reservoir fisheries, and protecting
significant natural areas.
2.2 Project Location
Progress Energy's Yadkin-Pee Dee River Project (Project) is located on the Yadkin and Pee Dee
rivers insouth-central North Carolina (Figure A-1). The Project consists of two developments, the
upstream Tillery Development and the downstream Blewett Falls Development. The Yadkin-Pee
River basin is the second largest in North Carolina covering 7,186 min measured at the North
Carolina-South Carolina state line. The Yadkin River originates near the town of Blowing Rock,
North Carolina and flows northeasterly for approximately 100 miles from the Blue Ridge Mountains
into the Piedmont physiographic region. As the river turns southeast, it enters an area in central
North Carolina that has experienced considerable urban growth. This growing urban area extends
from Charlotte to Raleigh/Durham and is known as the Piedmont Crescent. Just to the south of the
Piedmont Crescent, the region enters an area known as the Uwharrie Lakes Region. This region is
named for the chain of six reservoirs located along this reach ofthe Yadkin and Pee Dee rivers, the
lowermost two of which are Lake Tillery and Blewett Falls Lake. It is in this region that the
Uwharrie River joins the Yadkin River at the upper end of Lake Tillery to form the Pee Dee River
(Progress Energy 2003).
The flow of the Yadkin-Pee Dee River is affected by a federal flood control development and six
hydroelectric developments on the main stem of the river. The first development (traveling
downstream from the headwaters) is W. Scott Kerr Dam, a flood control project operated by

the U. S. Army Corps of Engineers (ACOE). The next four downstream developments make up the
Yadkin Project (FERC No. 219'x, owned by Alcoa Power Generating, Ina (APGh). These four
hydroelectric developments High Rock, Tuckertown, Narrows, and Falls are located along a
38-mile stretch ofthe Yadkin River (river miles [RM] 272 to 2340. High Rock Reservoir serves as
the primary storage and waterregulationfacilityforthe lower Yadkin-Pee Dee River (APGI2002).
Progress Energy's Tillery and Blewett Falls facilities are the next two hydroelectric developments
on the river, located at approximately RM 218 and 188, respectively. The North Carolina-South
Carolina state line is located at RM 173, approximately 15 miles downstream of Blewett Falls Dam.
Table A-1 provides the location and drainage area of each ofthe six FERC-licensed facilities. River
flows to Progress Energy's Tillery and Blewett Falls developments are largely dependent on releases
from APGI's Yadkin Project. Flow releases from APGI's Yadkin Project to Progress Energy's
Tillery Development are governed by aFERC-approved agreement between the parties. This
agreement requires APGIto operate in a manner that allows Progress Energyto meet its continuous
flow requirements. Yadkin's seasonal operations are managed in accordance with a "rule curve"
that guides the operation of High Rock Lake. The current rule curve, referred to as "Yadkin's
Operating Guides for Operation of Badin Works", is provided in Figure B-4.

3.0 Description oi' Primary Project Works
3.1 Tillery Development
The Ti11erS~ Dam and its powerhouse (see photo below) are located in NSontgomery and Stanly
counties, four miles west of Mount Gilead, North Carolina. The Tillery impoundment (known as
Lake Tillery) extends upstream 16 miles to the tailrace of APGI's Falls Development powerhouse.
Construction of the 'Illlery D ev el opment b egan in 1926 and the pl ant was placed in semi ce in 192 8.
The facilities have operated safely and reliably for 78 years.
The Tillery Development consists of a concrete gravitit° dam with 18 gated spillways; afour-unit
indoor-outdoor powerhouse; electricat stivitchyard; associated auxiliary electrical andmechanical
equipment; and recreational facilities located on the 16-mile-long reservoir.
3.1.1 Dams, Spillways, andP.eservoirs
3.1.1.1 LYams and Spallway
Tillery Dam (also known as Norwood Dam) consists of approximately 1,200 ft of earthen
embankment and 1,550 ft of concrete gravity structures. The concrete works include a 758-ft-long
spillway consi sting of a 62-ft-high ogee section, a concrete stilling basin, a 310-ft-long powerhouse
intake structure, and485-ft-long east andwestvon-overflow segments. The spillway at'Illlery is
controlled by 18 radial gates, each 34 ft wide by 24 ft high. Six of the gates can be partially operated
remotely from the powerhouse control room. The other gates can be operated by means of control s
located at the gates on the spillway deck. P, 14-ft-wide bottom-drop ta•ash sluice gate is located
between the powerhouse intake and spillway.
A-5

Application for License Yadln~n-Pee Dee River Hydroelectric Project
Two non-overflow structures form the abutments of the concrete gravity spillway and powerhouse
structures. The 176-ft-long west bulkhead has a top width of 6 ft and maximum height of 88.5 ft. It
is located between the gated spillway structure and the westerly earthen embankment. The east
abutment is 308 ft long with atop width of 20 ft and a maximum height of 88.5 ft. It is located atthe
east end of the powerhouse intake structure and extends to natural ground on the east abutment.
3.1.1.2 Reservoir
The Tillery Dam creates the impoundment known as Lake Tillery. The impoundment extends
approximately 16 miles to the tailwater of APGPs Falls Development. At the normal maximum
reservoir elevation of 277.3 ft3, Lake Tillery has a maximum depth of about 72 ft and a surface area
of approximately 5,697 acres. The lake is widely used by the public for boating, fishing, swimming,
camping, and other recreational activities. The lake has approximately 118 miles of shoreline
(Carolina Power & Light [CP&L] 2001) with approximately 55 percent being in residential or
commercial development.
The Tillery reservoir currently has a FERC-licensed usable storage capacity of 84,150 ac-ft at the
normal water surface elevation of 277.3 ft'.
Two municipal water supply intakes are located on Lake Tillery (see Figure E3-5 in Exhibit E3,
Water Use and Quality, for intake locations). These intakes are for the Town of Norwood and for
Montgomery County. The intake structure for the Norwood Water Treatment Plant is located on the
west shoreline, directly east of the Town of Norwood and approximately 2.5 miles upstream of
Tillery Dam. The intake is located downstream of the Cedar Creek tributary arm of the lake. The
intake pipe is situated approximately 25 ft below the normal reservoir level.
The Montgomery County Water Treatment Plants water intake is located on the east shoreline of
Lake Tillery approximately 500 yards upstream of the Tillery intake structure and dam
(Figure E3-5). Two intakes on the east shoreline serve the watertreatmentplant. Only one intake is
used at any one time. The lower intake pipe is located at elevation 255 ft or 22 ft below the normal
reservoir water surface elevation. It can be operated when the lake is too low to permit use of the
upper intake.
3.1.2 Powerhouse
The Tillery powerhouse is a concrete, indoor-outdoor structure containing four generating units,
each with a dedicated penstock and headgate, and Moody-type draft tubes. Each turbine drives a
direct-connected vertical-shaft generator. The turbine flow exits directly to the Pee Dee River. The
gross head is 72 ft. The powerhouse is integral with the dam.
3 All elevations are NAVD 88 datum.
This usable storage capacity is based on the maximum drawdown of 22 ft allowed under the current license. In
practice, Progress Energy has, by informal agreement with lakeshore owners, agreed to try to limit drawdowns to 1
to 2 ft durine mime recreational neriods.

Units 1 through 4 have headcovers that serve as the pressure boundary for the interface with the
powerhouse. For all four units, water is delivered from the reservoir and is discharged from the
turbines to a symmetrical, Moody-type draft tube with ahigh cone. The cone extends fromthe floor
of the draft tube to just below the turbine runner. The purpose of the high cone is to prevent
formation of draft tube vortices and to help mitigate whirl coming off the runner. The overall
purpose of the draft tube is to recover velocity head at the runner discharge. This configuration of
draft tube allows a relatively short distance from draft tube exit to the vertical centerline of the
generating unit, thereby reducing powerhouse size.
For Units 1 through 3, the turbine distributor centerline is set approximately 7 ft above the normal
tailwater level of 205.5 ft. Unit 4 turbine distributor centerline is also set at the same elevation as
Units 1 through 3 but the five fixed blades of this axial flow, propeller-type turbine are at a
centerline elevation of approximately 204 ft. This setting reduces the likelihood of cavitation
forming on the turbine blades or in the clearance between the blades and the turbine discharge ring.
3.1.3.2 Generators
The generators for Units 1, 2, and 3 are Allis-Chalmers three-phase, 60-cycle units. Units 1 and 3
are rated at 27,500 kVA at 0.8 p.f, 22 MW, and 13,800 V. Unit 2 is rated at 22,500 kVA at 0.8 p.f,
18 MW, and 13,800 V. Unit 4 is a Westinghouse three-phase, 60-cycle generator rated at
27,500 kVA at 0.8 p.f, 22 MW, and 13,800 V. A summary ofthe generator equipment is provided
in Table A-2. The generators for Units 1 through 3 were rewound in 1966, and Unit 4 was rewound
in 1993. The house generator is rated 563 kVA, 550 volts AC.
All four main generators are cooled using water-to-air heat exchangers. The fire protection system
is C02. All four units are provided with static exciters. The generator voltage of 13.8 kV is
A-7

Application for License Yadln~n-Pee Dee River Hydroelectric Project
stepped-up to a transmission voltage of 115 kV at the station transformers located on the
powerhouse deck.
3.1.4 Accessory Electrical Equipment
3.1.4.1 Main Power System
The Tillery power system is designed with two parallel three-phase, step-up transformers dedicated
to each of the four main units. Each unit has a 115 kV circuit breaker on the high side of the step-up
transformers for protection and synchronizing. Each unit is provided with static excitation, voltage
regulation, and protective relay system.
3.1.4.2 Electrical Auxiliary Systems
Unit control logic and metering are integrated within a programmable logic controller (PLC) for
each unit. This facilitates the monitoring and operation of the units from either the local control
room or remotely.
Primary station auxiliary power is provided by a 550 volt AC system. Each unit auxiliary
transformer feeds a shared "ring bus." The house generator, noted above, feeds into this 550-volt
ring bus. Station control power is provided by abattery-backed DC system.
3.1.5 Accessory Mechanical Systems
Typical auxiliary mechanical systems include cooling water, Tube oil, HVAC, and governor
hydraulic system. The original low-pressure governor servomotors and associated governor systems
were upgraded in 1991 with new high-pressure equipment. These high-pressure systems are
interfaced with the PLC systems noted above. The original low-pressure hydraulic system is still
used for the governor function on Unit 4.
A 150-ton gantry crane, including various auxiliary hooks, is located outdoors to facilitate
maintenance on the units.
3.1.6 Proposed Modifications to the Project Works of the Tillery Development
Progress Energy has no current plans to upgrade the existing power generation equipment.
Modification of Project facilities and/or operations will occur over the term of the next license as a
result of implementation of the following proposed environmental resource enhancements.
^ Water Quality -Progress Energy has developed a detailed program for meeting State of
North Carolina water quality dissolved oxygen (DO) standards at Tillery within three years of
issuance of a new license. Depending on the preferred DO enhancement technology, Project
operation and facilities may be subject to minor modifications. If facility modifications are
required, revised Exhibit F drawings will be submitted to FERC for approval.
^ Fish Passage -Progress Energy, in consultation with resource agencies, has proposed a fish
protection and passage plan that will consist of a phased approach based on a multi-year
program during the term of the next license period in order to meetthe goals and objectives of
the Pee Dee River Diadromous Fish Restoration Plan. Implementation ofthis plan may result

in chazige~ to Fc•oject facilities (e.g., construction of upstream fish passage facilities) and
operation(e.g.,dieer•tingflowthroughfishways). After facilitymodiflcationsarecompleted,
revised Exhibit F drawings will be submitted to FERC for approval.
3.2 Blewett Falls De~~elopment
Constt•uction of the Blewett Falls Development began in 1905. Financial problems prevented the
original builders from completing the Project. 'Ihe Yadkin River Power Company acquired the
rights to the Blewett Falls Development and finally brought the plant into service in June 1912.
Progress Energy acquired the Yadkin Power Company in 1926.
The Blewett Falls Dam andpowerhouse (see photo above) are located at RIVI 188 approximately 15
miles upstream of the North Carolina-South Carolina state line. The Blewett Falls Development
consists of a concrete gravity ungated spillway with 4-fl flashboards, easterly and westerly earthen
embankments, a forebay canal, concrete intake, powerhouse with six units, a tailrace whi ch rej Dins
the Pee Dee approximately 900 ft downstream of the dam, and a 12-mile-long reservoir.
3.2.1 Dams, Spillways, and Reservoirs
3.2.1.1 Dana arard Spaldway
The Blewett Fall s Dam is a 3,168-ft-1 ong structure consisting of a 1,700-ft-long earthen embankment
and a 1,468-ft-long concrete spillway and abuhnents. The 300-ft-long powerhouse intake is
separated from the spillway> by a portion of the westerly earthen embankment.
The spillway is a concrete gravity ogee-type structure topped by 4 ft of wooden flashboards which
are designed to fail at about 3 ft of overtopping. The permanent concrete crest is at elevation
A-9

Application for License Yadln~n-Pee Dee River Hydroelectric Project
173.2 ft. Training walls adjacent to the spillway have a top elevation of 197.2 ft. Additional
concrete gravity overflow sections are adjacent to the spillway and are approximately 150 ft long
with atop elevation of 181.2 ft.
Earthen embankments with concrete core walls are located on both ends of the spillway. The
easterly earthen embankment is approximately 870 ft long with a top elevation of 197.2 ft. The
westerly earthen embankment is approximately 850 ft long with a top elevation of 197.6 ft.
3.2.1.2 Reservoir
The Blewett Falls Dam creates the 12-mile-long Blewett Falls impoundment. The normal pool
elevation is 177.2 ft. The surface area of the lake at the normal operating pool is approximately
2,866 acres. The Blewett Falls shoreline is largely undeveloped. The lake is available to the public
for boating, fishing, and recreation. The lake shoreline is largely undisturbed, and the lake supports
good populations of game fish, especially crappie and largemouth bass.
The Blewett Falls reservoir has a usable storage of 30,893 ac-ft, corresponding to the 17 ft of
drawdown currently allowed by its FERC license. Under normal daily operations, the reservoir
fluctuates 2 to 4 ft to regulate flows coming from Lake Tillery and the Rocky River.
Two municipal water supply intakes are located in Blewett Falls Lake, one each for Anson and
Richmond counties (see Figure E3-6 in Exhibit E3, Water Use and Quality, for intake locations).
The intake structure for the Anson County W ater Treatment Plant is located on the west shoreline in
the lower portion of Blewett Falls Lake in the Smith Creek arm of the lake approximately 1.5 miles
upstream of the dam (Figure E3-6). The invert for this intake is at elevation 166.3 ft. Progress
Energy notifies the water treatment plant if they will be drawing down the reservoir below 170.7 ft.
The Richmond County intake structure is located on the east shoreline of Blewett Falls Lake less
than 1,000 yards upstream from the dam (Figure E3-5).
3.2.2 Intake and Powerhouse
The 300-ft-long Blewett Falls powerhouse is a concrete gravity structure with abrick-masonry and
steel superstructure. It is located at the downstream end of an approximately 300-ft-long forebay
canal. The gross head is approximately 52 ft. The Blewett Falls powerhouse contains six generating
units, each with its own penstock. Each of the turbine units drive adirect-connected, horizontal-
shaft generator. The turbines discharge via steel-conical draft tubes into a 900-ft-long tailrace
channel which reconnects to the Pee Dee River.
Flows are delivered from the forebay canal to an intake structure containing headgates, trashracks,
and penstocks. The intake delivers water to the six penstocks which house the turbine units. Two
small auxiliary units are also contained in the powerhouse. On the downstream side of the
powerhouse, a fishing platform extends across the entire building providing ADA-accessible
tailwater fishing.

3.2.3 Turbines and Generators
3.2.3.1 Turbines
The six Blewett generating units were commissioned in June of 1912. Each generator is driven by
two identical hydraulic turbines operating in tandem. Each turbine consists of two runners;
therefore, each unit contains four separate runners. This configuration is referred to as a "quad-
runner" alignment. Each of the 12 hydraulic turbines, manufactured by S. Morgan Smith, is of a
horizontal-shaft, double-opposed runner, single-discharge configuration. A summary of the
generating equipment at the Blewett Falls Development is presented in Table A-3.

The units are typically synchronized to the system and loaded to best-efficiency output when
operated. For Units 1 to 3, this occurs at a generator output of approximately 3,500 kW each at the
normal operating gross head of approximately 52 ft. The corresponding best-efficiency load for
Units 4 to 6 is approximately 4,200 kW. The units are run at maximum output during periods of
high inflows.
Water passing through the intake works is directed to the two turbines for each unit via a short 17-ft-
diameter section of steel penstock. This short section of penstock attaches to an 18-ft-diameter
pressure case, which houses both turbines. The pressure boundary for the interface with the
powerhouse is achieved by a single headcover per unit. The turbine discharge is then directed to the
tailrace by a single draft tube per turbine (therefore two draft tubes per unit). The turbine shaft
centerline of each generating unit is located approximately 20 ft above the normal tailwater level of
126 ft. The draft tube allows recovery of head which would otherwise be lost. This does, however,
significantly reduce the pressure on the low-pressure side of the turbine runners.
Duringthe late 1980s and early 1990s, the turbines were refurbished and new stainless steel runners
were installed. When the turbines were refurbished, new wicket gate and wicket gate bushings were
installed. Also, new wicket gate pins made from stainless steel were installed to address corrosion
problems. New draft tubes were installed on all units in the early 1990s.
Originally, there were two hydraulic turbine-driven DC generators that provided the field for
excitation of the main generators. These units were retired when the new static exciters were

Application for License Yadln~n-Pee Dee River Hydroelectric Project
installed in 1985 to 1986. The 4-ft-diameter penstocks, turbine pressure cases and at least part ofthe
turbines remain.
3.2.3.2 Generators
The original six generators were built by General Electric and are all 3-phase, 60-cycle, direct-
connected, indoor-type, horizontal-shaft generators. The generators for Units 1, 2, and 3 are
nameplate rated at 3,200 kW with a p.f. of 0.8, 4,800 V at full load. They are 164 rpm with
396 coils. Generators for Units 4, 5, and 6 indicate ratings of 5,000 kW at a p.f. of 0.75. A summary
of the generators is provided in Table A-3. Unit 1 generator was rewound in 1982, Units 2 and 4
were rewound in 1990, Unit 3 was rewound in 1986, Unit 5 was rewound in 1975, and Unit 6 was
rewound in 1973. Field current for each generator is provided by respective static excitation
systems.
3.2.4 Accessory Electrical Equipment
3.2.4.1 Main Power System
The electrical main power system for Blewett Falls is such that the generators are protected and
synchronized to the system with indoor, medium-voltage, vacuum switchgear breakers. Station
output from all units is stepped up to the 115 kV transmission system using three single-phase,
indoor, water-cooled, transformers operating as a single bank. The transformers are provided with a
water spray fire protection system. Current limiting reactors are installed between the step up
transformer bank and the switchgear bus. Control design is such that units can be started from the
plant control room. The units have black start capability. A single 115 kV circuit breaker is located
electrically on the high side of the step-up transformer bank. This breaker is located physically
within the powerhouse in an upstairs "high tension room."
3.2.4.2 Electrical Auxiliary Systems
AC and DC auxiliary power systems are typical, except for power to various DC motors. A
250 VDC rectifier system, with 480 VAC input, has been installed for feeding power to crane motors
and flood pumps.
3.2.5 Accessory Mechanical Systems
Typical auxiliary mechanical systems are provided for cooling water, Tube oil, HVAC, and governor
hydraulics.
The original governors were modernized and converted to gate positioners in the 1980s. Unit speed
is now regulated by the electrical inertia of the large power system grid once the units have been
synchronized. The gate positioners are then used only to control turbine power output by varying
wicket gate opening. A 40-ton crane is located within the powerhouse's generator room to facilitate
teardowns and maintenance.

3.2.6 Proposed Modifications to the Project Works of the Blewett Falls Development
Progress Energy has no plans to modify the existing power generation equipment. However,
modification of Project facilities and/or operations will occur over the term of the next license as a
result of implementation of the following proposed environmental resource enhancements.
^ W ater Quality -Progress Energy has proposed a detailed program for meeting State of North
Carolina water quality DO standards at Blewett Falls within three years of issuance of a new
license. Depending on the outcome of the different enhancement options analyzed, Project
operations and facilities maybe subject to minor modifications. If facility modifications are
required, revised Exhibit F drawings will be submitted to FERC for approval.
^ Fish Passage -Progress Energy, in consultation with resource agencies, has proposed a fish
protection and passage plan that will consist of a phased approach based on a multi-year
program during the term of the next license period in order to meetthe goals and objectives of
the Pee Dee River Diadromous Fish Restoration Plan. Implementation ofthis plan will result
in changes to Project facilities (e.g., construction of upstream fish passage facilities) and
operations(e.g.,divertingflowthroughfishways). Afterfacilitymodificationsarecompleted,
revised Exhibit F drawings will be submitted to FERC for approval.

4.0 Description of Other Project Facilities
4.1 Transmission
4.1.1 Tillery Transmission Facilities
Yadlnn-Pee Dee River Hydroelectric Project
An outdoor switchyard is located within the Project Boundary just east of the powerhouse. The
switchyard operates at 115 kV. It is arranged, electrically, in a single-bus, single-breaker
configuration. Each of the four generating-unit, step-up transformers feed a single 115 kV bus
through dedicated circuit breakers. Each of the four 115 kV transmission lines that exit the
switchyard has its own circuit breaker.
4.1.2 Blewett Falls Transmission Facilities
A single 115 kV line exits the Blewett Falls powerhouse and feeds into a small outdoor switchyard
located justnorth ofthe powerhouse withinthe Project Boundary. This yard contains 115 kV circuit
breakers for three circuits: one for an incoming line from adjacent combustion turbines, and two for
transmission lines that provide ties to other switchyards that are part of Progress Energy's system.
4.2 Recreation Facilities
The Project is located in the Uwharrie Lakes region ofsouth-central North Carolina. The Uwharrie
Lakes consist of six manmade lakes created as aresult ofthe construction of hydroelectric facilities,
including the Tillery and Blewett Falls developments. The Uwharrie Lakes provide a variety of
recreational opportunities including boating, canoeing, swimming, fishing, and most other water
sports. Detailed discussions regarding recreation resources and the facilities present at each lake are
provided in Exhibit E7.
4.2.1 Tillery Recreation Facilities
Progress Energy leases all of its public access areas to the North Carolina Wildlife Resources
Commission (NCWRC), which provides operation and maintenance for the recreation facilities.
^ Public Boat Access -Lake Tillery has four public access areass -the Lilly's Bridge boating
access areawhich includes two boat ramps, approximately one mile upstream of the dam, the
Swift Island boating access area which offers a large parking area and two paved boat ramps,
the Stony Mountain boating access area which offers a large parking lot and two paved boat
ramps, the Norwood boating access area which offers two paved ramps and a parking area.
^ Developed Fishing Area -The Lilly's Bridge fishing pier is located directly across from the
Lilly's Bridge Access Area.
^ Canoe Portage -Progress Energy maintains a canoe portage located on the west shore of the
dam.
There are numerous privately-operated recreation facilities and marinas on Lake Tillery as well.
s Public access to the lake is also provided at Morrow Mt. State Park. This access is managed by the State of North
Carolina, Division of Parks and Recreation.

Application for License Yadln~n-Pee Dee River Hydroelectric Project
4.2.2 Blewett Falls Recreation Facilities
Progress Energy also leases all of its public access facilities on Blewett Falls Lake to the NCWRC.
^ Public Boat Access - A total of two public access areas (Pee Dee and Grassy Islands) are
located at Blewett Falls Lake. There is also a small developed access site at the put-in area at
the end of the canoe portage route just below the dam. This site has a boat ramp and a gravel
parking area. Grassy Islands offers boating access via a paved ramp and has a small parking
area. The Pee Dee recreation area offers boating access and a large parking area.
^ Developed Fishing Area -Blewett Falls Development provides an accessible fishing pier for
the general public and persons with disabilities atthe tailrace justbelow the powerhouse. This
concrete fishing platform is attached to the powerhouse, and was cooperatively built with the
NCWRC. A paved parking area and walkway allows for easy access to the site.
^ Canoe Portage -Progress Energy maintains a canoe portage located on the eastern shore of
the dam.
4.2.3 Proposed Recreation Facilities
Since the issuance of the Initial Consultation Document (February 2003) and Joint Public Meeting
(March 2003), Progress Energy has worked closely with stakeholders to evaluate potential
protection, mitigation and enhancement (PM&E) measures to be implemented for the future
operation of the Tillery and Blewett Falls developments. After the completion of stakeholder
consultation and recreational studies (including a recreation survey), Progress Energy analyzed the
Project record and study findings to determine the need for recreational PM&E measures. Having
completed this evaluation, Progress Energy proposes certain recreational PM&E measures for the
Tillery and Blewett Falls developments.
The PM&E measures will provide the public with additional access and improved recreational
opportunities at the Project during the neat license term. According to the recreation studies
performed as part ofrelicensing, overcrowding at public access areas was not generally perceived as
an issue of concern by recreational users visiting facilities at either of the Project lakes. Issues
identified by recreational users were more related to misuse of the facilities and less to boater use
levels. Detailed site plans for recreational enhancements, the proposed implementation dates, and
the responsibilities ofthe involved parties will be filed with FERC after issuance ofthe new license.
4.2.3.1 Tillery Development
Progress Energy proposes to make several improvements atfour public boating access areas located
on Lake Tillery: the Lilly's Bridge, Swift Island, Norwood, and Stony Mountain access areas.
Generally, improvements to these areas include the addition of public sanitary facilities, trash
receptacles, improved parking areas, additional public information signage, and updatingthe Project
public information kiosks.
Progress Energy proposes to relocate the existing informal public boating access area located in the
tailrace immediately below the Tillery Plant (Figure E7-1). Progress Energy, in consultation and
partnership with the NCWRC, will develop and construct a new public boating access area located at
the mouth of Clarks Creek, approximately one-half mile below the power plant and one-quarter mile
from the current access area Public access to the Clarks Creekboating access area will be from the
A-15

Application for License Yadln~n-Pee Dee River Hydroelectric Project
power plant access road (i.e., Tillery Dam Road) which is located off State Road 1103 and NC
Highway 731. The boating access area will have a gravel parking lot with designated Americans
with Disabilities Act (ADA) parking places.
Progress Energy proposes to work with the NCWRC in co-funding with matching dollars for the
construction of a boat house and access ramp for use by enforcement personnel on Lake Tillery.
This facility will permitthe NCWRC to respond more effectively to boating emergencies on the lake
and serve as a central point for safe boating enforcement activities on the lake. The proposed
location is on the main lake side of the Project lands on the peninsula located adjacentto and south
of the Stony Mountain boating access area (Figures E7-1 and E7-5). Progress Energy will consult
with the NCWRC on effective means to discourage public use of the informal public access area at
State Roads 1740 and 1745, locally known as the Steel Bridge Area (see Figure E7-1). The
development of the public fishing pier at the nearby Stony Mountain boating access area will
provide additional public fishing opportunities that may be eliminated with the closure of this
informal access area.
4.2.3.2 Blewett Falls Development
Progress Energy proposes to build anew public boating access area on the Richmond County side of
Blewett Falls Lake within five years of issuance of the new license, if a suitable site can be
identified. Suitability will depend upon identifying a buildable site and obtaining the necessary
access across private lands. The new boating access areawould be located in the lower lake area in
the general vicinity of the opposite shore of the existing Pee Dee access area located on the Anson
County side of the lake (Figure E7-2). Progress Energy will work with local county officials and
interested landowners to site the new public boating access area.
Progress Energy proposes to include several improvements at the two public boating access areas
currently located on Blewett Falls Lake. At the Pee Dee Access Area, Progress Energy will provide
public sanitary facilities and trash receptacles; update the public information signage including a
new Project information kiosk; and improve parking facilities for vehicles and boattrailers. At the
Mountain Creek (Grassy Islands) Access Area, Progress Energy will provide trash receptacles;
update the public information signage including a new Project information kiosk; and improve
parking facilities for vehicles and boat trailers. At both sites, Progress Energy will also work with
the NCWRC to improve the boat ramps to permit effective boating accessibility over the range of
lake levels proposed for the new license term.
Progress Energy proposes to upgrade the canoe portage facility located on the east shoreline of
Blewett Falls Lake at the dam to applicable state recreational standards. Progress Energy will
provide an electronic link on its external Company Internet web site that will allow the public to
access real-time Pee Dee River streamflow data atthe USGS Rockingham gage station (IJSGS Gage
No. 02129000).

Application for License Yadln~n-Pee Dee River Hydroelectric Project
2.0 Background and Project Purpose
Progress Energy owns and operates the Yadkin-Pee Dee River Project (Project), located on the
Yadkin-Pee Dee River in North Carolina. The Project consists of the 84 megawatt (MW) Tillery
Development and the 24.6 MW Blewett Falls Development. Each development consists of a dam,
powerhouse, impoundment, substation, structures used in connection with the Project, water rights,
rights-of--way (ROW), lands, and interest in lands necessary for the operation and maintenance ofthe
Project. The Project produced an annual average of326 million kWh of renewable energy over the
20-year period of 1984 to 2003.
The Blewett Falls and Tillery developments were constructed in the early 1900s. Blewett Falls was
placed in operation in 1912 and the Tillery Development began operations in 1928. In 1958, the
Federal Power Commission, predecessor to the Federal Energy Regulatory Commission (FERC),
issued to Carolina Power & Light (CP&L) a 50-year license for the Yadkin-Pee Dee River Project
designated as FERC No. 2206. The Project has provided avaluable public service as a peaking and
load-following electrical generation resource throughout its history.
The primary purpose of the Project is to generate on-peak electricity and meet other significant
control area needs for the benefit of Progress Energy's ratepayers and the support of the electrical
grid. The Project is used for load-following and on-peak generation and its economic viability is
dependent on serving these purposes. Additionally, both Tillery and Blewett Falls have the
capability to "black start", meaningthe ability to come on-line under system blackout conditions to
support local loads and aid in overall transmission system restart and recovery.
The waters of the Pee Dee River in North and South Carolina have historically been managed for
numerous municipal, agricultural, public, and industrial uses including domestic and industrial water
supply, wastewater management, power generation, recreation, wildlife, and irrigation. Upstream of
Progress Energy's Tillery Development is the Yadkin Project, FERC No. 2197, owned and operated
by Alcoa Power Generating, Ina (APGI). The current FERC license for the Blewett and Tillery
developments states that "it is desirable and in the public interest that the operation of Project Nos.
2197 and 2206 be coordinated to the greatest extent compatible with the several and distinct
purposes for which the two projects are designed and operated." Currently, the primary storage
reservoir in the Yadkin-Pee Dee River system is High Rock Lake, APGI's uppermost impoundment.
High Rockfunctions as the primary seasonal storage and flow regulation facility forthe Yadkin-Pee
Dee River (APGI 2002). In contrast, the volume of active storage in the Blewett and Tillery
Reservoirs under current operations is only adequate to provide daily shaping and re-regulation of
flows delivered from APGI's system.
Progress Energy has ahistory of working cooperatively with upstream and downstream interests on
the Pee Dee River. Most recently, in 2002, due to unprecedented drought conditions in the basin,
Progress Energy worked with water resource authorities from the states ofNorth Carolina and South
Carolina and representatives from APGI to reach atemporary "drought" protocol to provide water
releases to satisfy the needs of downstream users. Another example of cooperation is Progress
Energy's active involvement in the Robust Redhorse Conservation Committee for the Pee Dee
River, a group made up of federal and state resource agencies and Progress Energy that is
investigating the presence and habitatuse ofthis fish species previously thoughtto be extirpated in
the Pee Dee River.

3.0 Project Operations
This section of Exhibit B describes in detail the operation of the Yadkin-Pee Dee River Project,
including relevant coordination agreements, and the seasonal adjustments to operations undertaken
to meetboth power and non-power goals. Project operations are described using weekly, daily, and
hourly flows recorded at the Tillery and Blewett Falls developments over the 1983 to 2003 time
frame. These time frames are appropriate because the current active reservoir storage in Tillery and
Blewett Falls are only sufficient to provide reregulation of Pee Dee River flows over a daily to
weekly time frame.
3.1 Coordination of River Flows
Progress Energy's 108 MW Yadkin-Pee Dee River Project, located as shown on Figure B-1, has
been continuously operated since 1928 (Progress Energy 2003). It is operated to provide peaking,
load-following, and ancillary services. Progress Energy operates the Project in coordination with
flow releases delivered from the upstream 209 MW Yadkin Project owned by APGI. Progress
Energy is required by its FERC license to provide continuous releases from its Tillery and Blewett
Falls developments of no less than 40 and 150 cfs, respectively.
The current FERC license for the Project states that the operations of the Tillery and Blewett Falls
facilities and the upstream Yadkin Project should be "coordinated to the greatest extent compatible
with the several and distinct purposes for which the two projects are designed and operated."
APGI's Yadkin Project consists of four developments: High Rock, Tuckertown, Narrows, and Falls.
In general, the APGI Yadkin Project is currently operated to provide power during on-peak periods.
There are no instantaneous minimum flow requirements. High Rock Lake, the uppermost reservoir,
is operated to provide seasonal storage; and Tuckertown, Falls, and Narrows are operated primarily
asrun-of--river developments. However, the Narrows and Tuckertown reservoirs have the ability to
fluctuate water levels up to 3 ft or more, and Falls is operated with a maximum daily fluctuation of 3
to 4 ft. High Rock Lake currently serves as the primary water storage and flow regulation facility
for the lower Yadkin-Pee Dee River (APGI 2002). Figure B-2 provides a river profile by river mile
(RM) illustrating the location of APGI's and Progress Energy's hydropower developments, and
Figure B-3 displays a watershed schematic of the Project area.
3.2 Overview of Operations of the Tillery and Blewett Falls Developments
The Tillery Development, with ahydraulic capacity of close to 18,000 cfs, plays afairly unique role
in Progress Energy's generation resource mix. The Tillery plant is Progress Energy's only load-
following hydro resource; and therefore plays a vital role for Progress Energy related to its control
area for load-following, load transfers across control areas, electrical grid stability, and area
frequency and voltage control. Therefore, in addition to providing valuable on-peak generation, the
Tillery plant provides other electrical system resource values that are difficultto replace with fossil-
fuel generation.

Tillery and Blewett Falls are operated in an integrated fashion. The peaking operation at Tillery
allows Progress Energy to provide electricity during periods of peak demand when its customers
need it most. In addition, because of its critical load-following and control areafunctions, Tillery is
often operated in Automatic Generation Control (AGC) mode to adjust to rapid changes in system
load and to enable local transfers of power between control areas. This type of operation can result
in relatively rapid changes in flow at Tillery that are then re-regulated at Blewett Falls. When daily
river flows drop below about 7,000 cfs (60 percent ofthe time), Blewett Falls is operated as a "block
loaded" facility, meaningthatthe units are either operated atbest efficiency or are off. Importantly,
Blewett Falls acts to re-regulate discharges from Tillery, thereby reducing the magnitude of flow
fluctuations that would otherwise occur downstream of Blewett Falls. When daily river flows at
Blewett Falls exceed about 7,000 cfs, the station operates in run-of--river mode. The maximum
turbine hydraulic capacity at Tillery is about 18,000 cfs and at Blewett Falls 9,200 cfs. This
difference in hydraulic capacity is indicative of the importance of the peaking and load-following
capability of Tillery, and it also underscores the need for close coordination of operation between the
two developments for flow management purposes.
Progress Energy's operations are significantly affected by operations and flow management at the
upstream Yadkin Project. As depicted in Figure B-3, flows to the Tillery plant are dependent upon
releases from APGPs Yadkin Project. In accordance with Article 29 ofthe Yadkin Projects FERC
license, the Yadkin Project must be operated in a manner that allows Progress Energy to meet its
continuous flow requirements. Yadkin's seasonal operations are managed in accordance with a "rule
curve" that guides the operation of High Rock Lake. The current rule curve, referred to as
"Yadkin's Operating Guides For Operation of Badin Works", is provided in Figure B-4. A FERC
Order Amending License issued in March 1968 (39 FPC 39'~ further requires Yadkin to maintain
certain lake levels for recreation purposes at High Rock Lake.
These operating guide curves provide descriptions of target generation amounts at specific
drawdown levels at the High Rock Lake. As drawdown level increases, the maximum allowable
generation decreases in an effort to maintain or increase water levels.
3.3 Headwater Benefits Agreement
On January 24, 1968, APGI filed with FERC a letter agreement (dated January 15, 1968) between
itself and CP&L (now Progress Energy) related to the settlement of headwater benefits in the
Yadkin-Pee Dee River basin. This agreement modified an agreement of February 19, 1926. The
1968 agreement includes the following relevant provisions for operation of High Rock Reservoir:
^ During the 10-week period preceding the recreation period (May 15 through September 15),
regulated weekly average streamflow from High Rock would be reduced to aflow of not less
than 1,500 cfs so as to permit High Rock reservoir to refill by May 15.
^ During the period May 15 through July 1, the regulated average weekly streamflow would be
reduced to a flow of not less than 1,610 cfs.
^ During the period July 2 through September 15, the regulated average weekly streamflow
would be reduced to a flow of not less than 1,400 cfs.

FERC found thatthe January 15, 1968 agreement constituted an effective and reasonable method of
compensation for headwater benefits received by Progress Energy at ProjectNo. 2206 from APGI's
Project No. 2197 in accordance with Section 13.1 of FERC's Regulations under the Federal Power
Act.
In practice, operations personnel at APGI's Yadkin Project provide a weekly release schedule to
Progress Energy operators the preceeding Friday. Tillery plant operations are then planned for the
week on the basis of the flow information provided by APGL Tillery operations, likewise, set the
stage for the operation of Blewett Falls. In the past, APGI operations have not always followed the
release schedule providedto Progress Energy, and this has resulted in disruptions to Progress Energy
operations. At the same time, APGI operations have very consistently met the terms of the
Headwater Benefits agreement.
3.4 Detailed Description of Project Operation
3.4.1 Tillery Reservoir Water Levels
As noted above, the inflow to Progress Energy's Tillery Development is almosttotally dependent on
the outflow from APGI's Falls Development. Flows from the unregulated Uwharrie River (drainage
area 373 min) enter Lake Tillery at the upper end of the lake. Summer and autumn flows from the
Uwharrie frequently fall below 50 cfs. Table B-1 provides drainage area and reservoir storage data
at each ofthe hydroelectric developments on the Yadkin and Pee Dee Rivers. Also as noted above,
APGI provides aweekly schedule ofreleases to Progress Energy. Information is also available daily
on water levels at, and inflows to, High Rock Lake.

Progress Energy's current FERC license allows drawdowns at Lake Tillery up to 22 ft below full
pond. Over time, Lake Tillery has become a popular recreation destination, and valued residential
location. Through the last dozen years, Progress Energy has voluntarily made its best efforts to
operate Lake Tillery within a 4-ft range under normal conditions, and much of the time operates
within a 1- to 1.5-ft range. Progress Energy also has an informal agreement with the North Carolina
Wildlife Resources Commission (NCWRC) to maintain Lake Tillery levels during the period of
April 15 to May 15 within approximately 1 ft of full pond to enhance largemouth bass spawning.
B-8

Application for License Yadln~n-Pee Dee River Hydroelectric Project
The gross storage capacity of the Tillery Reservoir is approximately 134,300 ac-ft. The usable
storage capacity under the existing licensed 22-ft drawdown is 84,150 ac-ft. The usable storage
capacity of Tillery Reservoir within the top 1.5 ft of the lake elevation (277.3 to 275.8 ft) is
8,260 ac-ft and within the upper 4 ft is 19,000 ac-ft.
Outflows fromthe Tillery Development flow into Blewett Falls Lake afterpassingthrough a 19-mile
reach of the Pee Dee River. Under normal operating conditions, it takes approximately eight to
10 hours for releases from the Tillery Development to be observed at the Blewett Falls Reservoir.
This time oftravel varies depending on the amount of flow being released. Time oftravel between
Tillery and Blewett Falls must be considered when planning Blewett releases.
3.4.2 Blewett Falls Reservoir Water Levels
The Blewett Falls Development is operated in coordination with the upstream Tillery Development.
When river flows are less than about 7,000 cfs (60 percent ofthe time), the normal daily operation of
the Blewett Falls Development results in a daily water level fluctuation of approximately 2 to 4 ft.
This cycling provides the storage capacity needed to reregulate the outflow from the Tillery
Development and adjustforthe time oftravel between Tillery and Blewett Falls. The Blewett Falls
turbine-generator units normally begin operation at about the same time as Tillery Plant generation
begins. Due to the travel time from Tillery to Blewett Falls, this results in Blewett Falls Lake being
drawn down up to approximately 3 ft before water arrives from Tillery. Generation at Blewett Falls
generally ends by 10:00 p.m., allowing the reservoir to refill. This operating method provides power
during daytime peak hours when there is a higher demand for electricity, while it reduces inadvertent
spill. The difference in hydraulic capacity between Tillery and Blewett Falls could result in
significant spill at Blewett Falls if adequate storage capacity were not available.
The gross storage of the Blewett Falls Reservoir is approximately 30,100 ac-ft at the normal
reservoir elevation of 177.2 ft. The usable storage capacity based on the current FERC-licensed
minimum pool elevation of 160.2 ft (a 17-ft drawdown) is approximately 24,000 ac-ft. However,
intake submergence can limit the allowable drawdown to about 11 ft (elevation 166.2 ft) which
corresponds to about 9,826 ac-ft of storage. The usable storage capacity in Blewett Falls Reservoir
in a 6-ft operating band from elevation 177.2 to 171.2 ft is 12,500 ac-ft.
3.4.3 Description of Project Power Operations
The Tillery Development is operated as a peaking and load-following facility. Typical current
operation includes daily (weekday) generation and load-following during hours of peak demand with
dispatch and output varying seasonally based on peaksystem loads and water availability. Whereas
the Tillery plant can operate in a variety of modes to support Progress Energy's Control Areas, the
Blewett Falls Development is operated as a "block-loaded" facility, meaning the units are either
operated at best efficiency or are offwhen flows are less than the plant's best gate discharge (about
7,000 cfs). The turbine hydraulic capacity of Blewett Falls is significantly less than that of Tillery;
therefore, in order to avoid spilling water, the Blewett Falls Development must anticipate flows from
Tillery generation and begin generating in advance of flows reaching Blewett Falls. This also serves
to re-regulate peaking flows from Tillery using the Blewett Falls Lake storage to reduce flow
fluctuations. When river flows exceed Blewett Falls best gate capacity (40 percent ofthe time), the
B-9

Application for License Yadkin-Pee Dee River Hydroelectric Project
plant is operated in arun-of--river mode. An example of a typical weekly operation of the Tillery
and Blewett Falls developments is presented in Figure B-5.

Figure B-5 Example of weekly operations of the Tillery and Blewett Falls developments.
3.4.4 Description of Non-Po1~/er Operations
Periodic Proj ect maintenance may require the loti~~ering ofthe reservoir levels at both developments.
At Tillery, these drawdowns are associated with the maintenance ofthe spillway gates, repairs to the
powerhouse intake trashrack, maintenance of the raw seater f-filtration system, or minor repairs to the
upstream riprap slope of the earthen embankment. Drawdowns required at the Blewett Falls
Development are similar to Tillery except the most frequent maintenance requirement is to service
the 4-ft-high wooden flashboards atop the spillway. During periods of high inflow, loss of
flashboards may occur and board replacement requires that the lake be lowered about 5 to 6 ft to
safely perform the necessary maintenance.
Other non-power operations include the maintenance of lake levels from April 15 to I~/Iay 15 within
1 ft of full pond {to the extent practicable) to enhance bass spawning, and the maintenance of
minimum flows at both developments. The FERC license requires that at Tillery a continuous
minimum release of 40 cfs be maintained at all times. The USGS periodically measures the
minimum release flow at Tillery. Based on these historic measurements, the actual current minimum
release below Tillery is roughly 7Q to 84 cfs. At Blewett Falls, the FERC license currently requires
a continuous minimum release of 150 cfs. Based on flows recorded at the USGS gage at
Rockingham located below the Blewett Falls Project, the actual continuous flow at Blewett is
seldom less than 250 cfs.
Lake levels at Tillery are often controlled to enhance non-power operations, primarily recreation.
Lake Tillery has become a popular recreation resource, especially during the mid-l~1ay to mid-
October heaiy-use boating season. Over time, Progress Energy has voluntarily limited its
B-10

Application for License Yadln~n-Pee Dee River Hydroelectric Project
drawdowns at Tillery to 4 ft, and during the recreation season, best efforts are made to limit
fluctuations to within the top 1.5 ft of the lake.
3.4.5 Project Operations Under Wet, Normal, and Dry Conditions
Mean daily flows at the Tillery and Blewett Falls developments for a wet, normal, and dry year are
provided in Figures B-6 through B-8, respectively.
As discussed in Section 3.4.3, the Blewett Falls Development is operated as ablock-loaded facility,
where individual generating units are typically either operated at best efficiency or are off. With all
six units operating at best gate, the turbine discharge at Blewett Falls is approximately 7,200 cfs.
Tillery is used as aload-following facility where operational flexibility is more critical than
efficiency. The hydraulic capacity of Blewett Falls is significantly less than Tillery; therefore, at
times, Blewett Falls must be operated in anticipation of flows from Tillery and begin generating in
advance of flows reaching the lake. Frequently, Tillery operates within a normal daily operating
band of 1 to 1.5 ft; however, this operation can vary seasonally, as both developments are dependent
on inflows from APGI's Yadkin Project. Under current typical operations, APGI discontinues
generation (and flows) on weekends, thus significantly reducing the inflow to Progress Energy's
Project. Project operations over atypical week atthe Tillery and Blewett Falls developments during
wet, normal, and dry years by season are depicted inthe series of generation charts described below.
^ Winter Operation (December to February)
Figures B-9 through B-11 represent typical weekly operations at the Tillery and Blewett Falls
developments during wet, normal, and dry years, respectively. During this time of year, electrical
system demand maybe higher than normal, and river flows are generally higher than summer and
fall months. Blewett Falls often operates in arun-of--river mode during this time of year (see
Thursday through Sunday below).
A review of Figures B-9 through B-11 shows a consistent block-loaded operation at Blewett Falls
and aload-following and/or peaking operation at Tillery. The primary variation in the operation is
the amount of water passed through the developments under wet, normal and dry conditions.
Review of the daily operation of each development shows that Tillery generation can change rapidly
to accommodate changing system electrical demand. This represents a vital resource for Progress
Energy and its customers. Conversely, Blewett often operates near best efficiency with eitherthree
or six units online and responds to inflows from Tillery.
^ Spring Operations (March to May)
Figures B-12 through B-14 present a summary of typical springtime operations over a weekly period
at the Tillery and Blewett Falls developments during wet, normal, and dry years, respectively.
During this time-frame, river flows are typically higher than normal and Blewett Falls is very
frequently operating in arun-of--river mode.

Figure B-14 Tillery and Blewett Falls springtime operations during a dry year (2001).
Review of Figures B-12 through B-14 indicate generally similar operations as those during winter
months. Higher flows are typically highest during this time of year, and Blewett Falls is normally
operating in arun-of--river mode in March and April. However, Figure B-14 also indicates that lo«~
flows can occur at any time of year in the Pee Dee watershed, and that the relatively small amount of
reservoir water storage is often not adequate to maintain higher generation releases.
Figure B-12 indicates the etTect of high tributary inflows to Blewett Falls from the Rocky River
(drainage area 1,413 mil) and the Little River (drainage area 350 mi2). Both of these tributaries
enterthe Pee Dee River between Tillery and Blewett Falls. Both of these rivers are unregulated and
tend to be very "flashy" with mean monthly flo~~~s being significantly higher than median monthly
flows. This is discussed later in Exhibit B, but is a significant factor ~~~hen considering t~-•hat
continuous minimum flows below Blewett Falls are achievable 100 percent of the time.
^ Summer Operations (June to August)
Figures B-15 through B-17 present a suinmaiy of summertime operations over a typical week at the
Tillery and Ble«~ett Falls developments during i~~et, normal, and dry years, respectively. During this
time-frame, flows are generally relatively low at the Project compared to winter and spring.
However, as Figure B-15 indicates, river flows can be high even in summer months. Intense
summer rains can produce very high flows rapidly in the unregulated Rocky River and Little River
drainages. Due to the lack ofwater storage, these tributary flows can then drop off just as quickly.
Figure B-17 indicates that low summertime flows can, under current operations, result in extended
periods where both Tillery and Blewett Falls releases are limited to minimum flows at both
developments.

Figure B-17 Tillery and Blewett Falls operations during summer in a dry year (20Q1).
^ Fall Operations (September to November)
Figures B-18 through B-20 present a summary of fall operations over a typical week at the Tillery
and Blewett Falls developments during wet, normal, and dry years, respectively. During this time-
frame, flo~~~s are generally low at the Project, but can also be quite unpredictable due to hurricane
acti~~ity. Even so, the driest months of the year are often October and November.
Figures B-18 through B-20 indicate similar operating trends as during the surmner season.
3.4.6 Flow Duration Cu1•~•=es
Flow duration curves representing historic Project outflows were developed from the records of the
USGS for its Pee Dee River at Rockingham, North Carolina gage (No. 02129000) which is located
3.3 miles below Blewett Falls Dam. The drainage area above the Rockingham gage is
approximately 6,863 miZ. The drainage area at Blewett Falls dam is 6,839 mil, or 99.6 percent ofthe
drainage area at the gage. The USGS-gaged flows are recorded on a 15-minute basis, and mean
daily flows are calculated and published by the USGS. The Rockingham station has been in
continuous operation at its present location since 1928. Annual flow duration curves for the
Rockingham gage are provided in Figure B-21. For general information purposes, flow duration
information is also provided for the Pee Dee River at the Pee Dee gage located in South Carolina,
with a drainage area of 8,830 miZ. Monthly and seasonal flow duration curves for each gage are
provided in Appendix B-3.
As indicated on Figures B-21 and B-22, the 1983 to 2003 hydrologic period compares fairly well
with the longer period of record. The 1983 to 2003 data are presented because the Tillery and
Blewett Falls plant flow and generation data were readily available for this time frame.

4.0 Description of the Yadkin-Pee Dee River Watershed
4.1 Project Setting
In order to develop an understanding ofthe Projects resource utilization characteristics presented in
Section 5 of this Exhibit, it is first helpful to have an understanding ofthe hydrologic characteristics
ofthe Yadkin River and Pee Dee River watersheds. The Pee Dee River, at its mouth at Winyah Bay,
South Carolina is one of the larger rivers on the east coast of the U. S. Given the Projects location
just a short distance upstream of the North Carolina-South Carolina state line, Projectflows can and
do affect river flows in North Carolina and portions of South Carolina.
The Yadkin-Pee Dee River Project is located on the Pee Dee River in the south-central region of
North Carolina, approximately 50 miles east of Charlotte and 60 miles south of Greensboro. The
Yadkin-Pee Dee basin is the second largest in North Carolina, draining atotal area of 7,186 min at
the North Carolina-South Carolina state line and containing approximately 5,991 linear miles of
freshwater perennial streams and rivers in North Carolina (North Carolina Division of Water Quality
[NCDWQ] 1998). The Yadkin River and the Uwharrie River meet atthe upper end of Lake Tillery
to become the Pee Dee River. The Pee Dee River drains an area of approximately 6,839 min
upstream of Blewett Falls Dam, and the drainage area at Tillery Dam is approximately 4,600 min
(Progress Energy 2003). The major tributaries in the Project area include the Uwharrie, Rocky, and
Little Rivers (see Figure B-1).
Approximately 15 miles downstream of Blewett Falls Dam at RM 173, the Pee Dee River enters the
State of South Carolina. The river flows more than 170 miles in primarily a coastal plain
physiogrpahy until it enters the Atlantic Ocean at Winyah Bay. The drainage area of the Pee Dee
River at Winyah Bay is 16,220 min.
Drainage areas oftributaries over 50 min enteringthe Pee Dee River between Falls Dam and Winyah
Bay are presented in Table B-2.

The Yadkin-Pee Dee River Project is part of a series of six hydroelectric developments located along
the main stem ofthe Yadkin and Pee Dee Rivers in North Carolina. Above these hydropower dams
is the W. Kerr Scott Dam, a federal flood control project operated by the Army Corps of Engineers
(ACOE). The nextfour dams are hydroelectric developments High Rock, Tuckertown, Narrows,
and Falls which make up the Yadkin Project (209 MW), owned and operated by APGI, located
along a 38-mile stretch of the river from RMs 272 to 234. High Rock Reservoir serves as the
primary storage and water regulation facility for the lower Yadkin-Pee Dee River (APGI 2002). The
next and final two hydroelectric developments on the river, located approximately at RMs 218 and
188, respectively, are the Tillery and Blewett Falls developments, which constitute Progress
Energy's Yadkin-Pee Dee River Project. The Pee Dee river flows unobstructed for the next 188
miles to the head of Winyah Bay in South Carolina.
4.2 Physical Description of River Basin
The Pee Dee River has its headwaters in the Blue Ridge Mountains ofnorth-central North Carolina,
then flows through the Piedmont region of central North Carolina and thence into the Uwharrie
Lakes region where the Project is located. Below the Blewett Falls plant, the Pee Dee River flows
another 188 miles through the upper and lower Coastal Plain region before it reaches the Atlantic
Ocean at Winyah Bay near Georgetown, South Carolina (Figure B-1). The river is an important
regional resource for power generation, recreation, wildlife habitat, domestic and industrial water
supply, and wastewater dilution (Yadkin-Pee Dee Lakes Project website 2002).
The Tillery and Blewett Falls developments are located in the Uwharrie Lakes region in North
Carolina's central Piedmont. This region consists of rolling hills accentuated by one of the oldest
mountain ranges in North America the Uwharrie Mountains (Yadkin-Pee Dee Lakes Project
website 2002). The Uwharrie Mountains are aligned northeastto southwest in the Project area and
range up to elevation 1,000 ft (LT. S. Department of Agriculture [USDA] 2001). The Uwharrie River
flows through this region and joins the Yadkin River below Falls Dam to form the Pee Dee River.
The Project is located in a rural part of North Carolina characterized by rolling hills. Much of the
land in the immediate vicinity of the Project is managed for timber production.
Lake Tillery has experienced significant shoreline residential development. On the other hand,
while there are over 1,000 homes and cottages along the Tillery shoreline, there are only a few
homes or seasonal dwellings adjacent to Blewett Falls Lake. The area of the state centered on the
six reservoirs has been termed North Carolina's "Central Park." The Central Park area has been
considered by some organizations as aregion that can serve as arural hub for outdoor recreation and
tourism for both local residents and residents of the surrounding metropolitan areas (Appalachian
State University [ASU] 1999).
B-23

Application for License Yadln~n-Pee Dee River Hydroelectric Project
Downstream from Blewett Falls Dam, the Pee Dee River flows approximately 15 miles in North
Carolina until it enters South Carolina. From there, it continues for another 173 miles through
bottomland forests and eventually into swamp lands and the coastal flats before it empties into the
Atlantic Ocean via Winyah Bay. Much ofthe area in South Carolina is rural; however, the Pee Dee
River is importantto municipalities and industry alike as a source of water supply and for receiving
treated wastewater. The municipalities in South Carolina that utilize the Pee Dee river for water
supply and/or wastewater disposal include Bennettsville, Cheraw, Florence, and the Grand Strand
Water and Sewer Authority. Industries and commercial development in proximity to the river are
located primarily in the areas near Cheraw, Bennettsville, Florence, City of Georgetown, County of
Georgetown, and Myrtle Beach.
4.3 FERC-Licensed Hydroelectric Projects
Six hydroelectric projects have been constructed within a 65-mile reach ofthe Yadkin and Pee Dee
Rivers extendingfrom Salisbury, North Carolinato Rockingham, North Carolina. From upstream to
downstream, these developments are High Rock Dam, Tuckertown Dam, Narrows Dam, Falls Dam,
Tillery Dam, and Blewett Falls Dam (Figure B-1). The ownership, generating capacity, and
hydraulic capacity of each ofthe lower Yadkin River and Pee Dee River projects are summarized in
Table B-3.

at High Rock Dam is 217,400 ao-ft. The remaining projects have significantly lower usable storage
capacities.

^ Pee Dee River at Pee Dee, SC; USGS # 02131000; 1938-present
The Yadkin and Uwharrie River gages are located upstream of Progress Energy's developments.
The Little and Rocky River gages are located on tributaries that enter the Pee Dee River between the
Tillery Development and the Blewett Falls Development. The Pee Dee River gage at Rockingham is
located 3.3 miles downstream of the Blewett Falls Project and is the primary gage used to record
flows released by the Blewett Falls Development.
Three additional USGS gages are located on the main stem of the river downstream of the
Rockingham gage: USGS No. 0213056 near Bennettsville, South Carolina, USGS No. 02131010
downstream ofPee Dee, South Carolina, and USGS No. 021352101ocatednear Plantersville, South
Carolina. In addition, two other gaging stations, Uwharrie River near Eldorado, North Carolina
(USGS No. 02123500) and Little River near Star, North Carolina (USGS No. 02128000) are located
in the Project vicinity.

4.4.2 Hydrology
The APGI and Progress Energy reservoirs are located in the upper-middle portion of the Pee Dee
River basin. The basin has mild, dry summers with little precipitation, and cool, wet winters with
moderate to heavy precipitation. The average annual air temperature measures about 61°F, with a
daily average maximum of about 72°F and daily average minimum of about 50°F. River flows in
the basin are derived primarily from precipitation in the watershed. The area receives high flows
during winter months and early spring (January through April). The late summer and fall hurricane
season between August andthe end ofNovember can produce large amounts ofprecipitation in brief
periods, producing spikes of flow through the system. Low flows typically occur during late
summer and early fall months. The average annual precipitation is about 47 inches (Progress Energy
2003).
The primary hydrologic record of historic flows from Blewett Falls Dam is the USGS gage at
Rockingham (No. 02129000) located 3.3 miles downstream from the dam. The gage has been in
continuous operation since 1928. There are no significant inflows to the Pee Dee River between
Blewett Falls Dam and the gage.
Representative streamflow data from the respective gages are presented in Figures B-24 to B-27.
Figure B-24 shows a comparison of mean daily flows for two long-term periods, 1928 to 2003 and
1983 to 2003 recorded at the USGS gage No. 0212900 at Rockingham, North Carolina, which is
located downstream of the Blewett Falls Development at RM 185. (The mean daily flows are
calculated for each day ofthe year overthe multi-year period; such thatforthe 1928 to 2003 period,
the mean daily January 1 flow is calculated as the mean of all the January 1 values in the defined
timeframe.) There are 24 min of additional drainage area between the development and the gage
location, for a total drainage area of 6,863 min at the gage.
Figure B-24 illustrates the relatively unregulated flow regime of the river and shows that mean
spring flows generally approach flow magnitudes of three-times greater than the mean summer
flows. This seasonal variability is due to the lack of significant storage or regulation offlows forthe
drainage area below APGPs High Rock development, where the river has an additiona12,800 min of
drainage area below High Rock to the gage. The shape of the mean daily flow curve indicates the
variability in precipitation, producing large spikes of flow primarily within the spring and summer-
fallhurricane season. (NOAA defines the official hurricane season as June 1 to November 30.) The
comparison of the two curves also illustrates the similarity of the shorter 20-year period of 1983 to
2003 to the longer term 1928 to 2003 record.
Figure B-25 shows a similar plotforthe USGS gage No. 02131000 Pee Dee River at Pee Dee, South
Carolina, located at RM 100.2, 84.8 miles downstream of the Rockingham gage, having a total
drainage area of 8,830 min. Figure B-24 shows a comparison of mean daily flows for two periods;
the 1939 to 2003 gage record, and a shorter 1983 to 2003 period. Figure B-24 shows the same
unregulated behavior as the Rockingham gage; however, the spikes of mean flow in the record are
less extreme (more gradual) due to the attenuation of the peak flows through the 84.8 intervening
RMs of wetlands and flood plains below the Rockingham gage.
Figures B-26 and B-27 present the mean daily flow for each year in the record for the Pee Dee River
at the USGS Rockingham gage and the Pee Dee gage, respectively. The figures illustrate the
B-27

Application for License
Yadkin-Pee Dee River Hydroelectric Project
variability in the annual mean daily river flow values, from a low at the Rockingham gage in 2001 of
2,740 cfs to a high in 2003 of 14,140 cfs. The mean and median daily flow for the period of record
is superimposed on the graph to illustrate the relative variances from the amn~al values. The
comparison between the mean and the median daily flow values for the period of record illustrates
the influence of the high-flow events that skew the mean value significantly from the median value.

Flow data record for the 1983 to 2003 period compare well to the longer term record of 1928 to
2003. The 1983 to 2003 period contains 20 years of recent data incorporating Project operations
under current conditions, the recent urban development and changes in the drainage basin, and a
reasonable balance ofwet and dry years, includingthe drought ofrecord and the wetyear ofrecord.
For purposes of Project operations modeling, Progress Energy used the 1983 to 2003 period because
it was representative of the longer term flow record, better represented more recent Project
operations (e.g., lake levels), and corresponded to the availability of daily plant records.
Over the period of record (1928 to 2003), the mean annual flow at the Rockingham gage is
approximately 7,978 cfs, and has varied from a low of 2,740 cfs in 2001 to a high of 14,140 cfs in
2003. By comparison, the mean annual flow at the Pee Dee River at Pee Dee gage is approximately
9,829 cfs, and has varied from a low of 3,755 cfs in 2001 to a high of 15,958 cfs in 2003. This
equates to an annual variability of mean runoff ranging from 34 to 177 percent of the long-term
mean annual flow for the Rockingham gage, and an annual variability ranging from 38 to 162
percent ofthe mean flow forthe Pee Dee gage. These ratios are reflective of awatershed with a low
active storage/mean annual runoff ratio.
Statistical analyses were performed onthe Rockingham gage data to develop monthly and seasonal
flow duration curves and identify typical wet (2003), dry (2001), and average (1997) flow years.
This information is provided in Appendix B-3.
4.4.2.1 Flood Flows
The flood of record for the Blewett Falls Development occurred in August 1908 (Arcadis 1997a).
Duringthis event, the discharge below Blewett Falls Dam reached a peakflow of 276,000 cfs at the
Rockingham gage (No. 02129000) on August 27, 1908 (USGS 2005). During the August 1908
event, the peak discharge at Blewett Falls was 270,000 cfs when the flood crested at aheadwater of
elevation 188.1 ft and tailwater at elevation 159.7 ft. A flood nearly equal to the 1908 event
occurred in September 1945. Based on plant records, the peak discharge duringthis event was also
approximately 270,000 cfs.
The flood of record at the Tillery Development occurred during the September 1945 flood event
(Arcadis 1997b) due to Hurricane Hazel, coming atthe end of adroughtperiod. The peakdischarge
at Tillery Dam was 160,000 cfs. Duringthis event, apeakflow of 220,000 cfs was recorded atthe
Pee Dee River at Pee Dee, South Carolina gage on October 7, 1945 (LTSGS 2005).
Additional notable floods occurred during Hurricane Gracie during September 29 to 30, 1959,
Hurricane Hugo on September 21, 1989, Tropical Storms Klaus and Marco during October 10 to 12,
1990, and Hurricane Floyd during 1999.
A summary of the annual peak flows measured at the Rockingham gage in the 1928 to 2003 period
is shown on Figure B-28. The seasonality of those annual peak flows is shown on Figure B-29,
illustrating the significance of the hurricane/tropical storm precipitation events. Figures B-30 and
B-31 present the flood information for the Pee Dee River at Pee Dee, South Carolina gage. A
summary of the annual and monthly maximum flows, as well as mean and minimum flows, as
measured at the Rockingham and Pee Dee gages are presented in Table B-4. The flows presented
are based on mean daily flows for the period of record at each gage.

A flood flow recurrence analysis was performed on the 1928 to 2004 annual peak flow datafor the
USGS gages at Rockingham and Pee Dee. Figure B-32 shows the result of this analysis, where a
regression curve was performed fitting the annual peak flows to a recurrence interval. This curve
shows that the 100-year flood (a flood having a recurrence probability of occurring once in a
hundred years) is approximately 225,000 cfs for the Rockingham gage, and 150,000 cfs for the Pee
Dee gage. It is interesting to note that the downstream gage actually has less of a peak flood value,
due to flow attenuation caused by the downstream flood plain and wetlands. This is an important
characteristics of the Pee Dee River in the coastal plain region.

Figure B-32 Flood flo«~ frequenc3~ curves for the USGS gage at Rockingham, North
Carolvia and Pee Dee, South Carolina.
A summary of the monthly minimum, maximum, and mean flows measured at the Rockingham and
Pee Dee gages is presented in Table B-4 above. The flows presented are based on daily flows for
the period of record measured at each gage. The minimum seven-day flow «~ith a 10-year
recurrence interval (7Q 10) at the Rockingham and Pee Dee gages has been estimated to be 765 cfs
and 1,450 cfs, respectively for the 1928 to 2003 period of record at Rockingham and the 1939 to
2003 period of record at Pee Dee.
The long-term {1928 to 2003} mean daily flow on the Pee Dee River at the Rockingham gage is
approximately 7,978 cfs. Further downstream at the Pee Dee gage, the long-teen (1939 to 2003)
mean daily flow is approximately 9,829 cfs.
An extended drought occurred in the Pee Dee River through the period 1998 to 2002. The Yadkin-
Pee Dee River basin reached "exceptional drought" classification, the most serious category, in the
sununer of 2002. These extreme drought conditions jeopardized the traditional uses of the river
including public and private water supplies, power generation, and recreation. To respond to the
public health and safety concerns that had arisen as a result of the drought, Progress Energy worked
proactively with water resource authorities from both states, as well as APGI, to collaboratively
develop a water release protocol for the coordinated operation of both Progress Energy's and
APGI's hydroelectric projects. Progress Energy agreed to release a average daily flow of 900 cfs as
measured at the USGS Rockingham gage. This release was sufficient to meet the needs of
downstream users located on the lower Pee Dee River in South Carolina. during this ez~treme drought
period. These users had been affected not only by the drought conditions in the mainstem Pee Dee
River but also by the reduction in tribLltary flows into the Pee Dee River, which had been severely
reduced or eliminated due to the drought conditions. Progress Energy also agreed, as described in
the "Emergency Drought IVlanagement Protocol", to continue release ofthe 900 cfs until the parties
agreed that the drought had passed or March 6, 2003, whichever came first (Appendix B-2).

4.4.2.2 Unregulated Hydrology
A 74-year streamflow datasetwas developed by APGI in cooperation with Progress Energy for each
of the six hydropower developments, and other areas of interest, using USGS gages located
throughout the Yadkin and Pee Dee River basin. This daily streamflow dataset, which is referred to
as the "APGI Flow Dataset", covers the October 1, 1929 to December 31, 2003 period of record
(POR) and extends from the W. Kerr Scott Dam on the upstream end to the Pee Dee River at Pee
Dee, South Carolina gage on the downstream end. Details regardingthe development ofthe "APGI
Flow Dataset" are discussed below.
Inflows to W. Kerr Scott Dam, the most upstream dam on the Yadkin River, were back-calculated
based on ACOE published outflow, change in storage, and precipitations records and estimated
evaporation rates, for the 1962 to 2003 POR. For the 1939 to 1962 POR, inflows to W. Kerr Scott
were determined usingthe tributary flows atUSGS Wilkesboro gage station minus tributary flows at
the USGS Reddies River gage station, with the difference prorated for the drainage areato W. Kerr
Scott. For the 1929 to 1939 POR, inflows to W. Kerr Scott were estimated using the drainage area
ratios and data from the Wilkesboro gage.
Proceeding downstream, the USGS Yadkin College gage record extends back beyond 1930. The
inflows (referred to as "gains") to this node are the difference between the gage flows and Kerr Scott
inflows, priorto W. Kerr Scottregulation, or the difference betweenthe gage flows and the W. Kerr
Scott discharges, since the construction of W. Kerr Scott Dam.
The scarcity of gages on the main stem of the Yadkin River between Yadkin College and
Rockingham complicatedthe development ofthe inflows between these two gages. At High Rock, a
USGS gage was present from 1919 to 1927 and 1941 to 19623. To facilitate the development ofthe
missing flow record (1929 to 1941 and 1962 to 2003), Fillin4, a program developed by the USGS,
was utilized. Working on monthly data, Fillip was used to correlate flows at a location of interest
with flows from gages in the watershed. Using regression techniques, Fillip uses those locations
with the highest correlations (depending on the month and year) to "fill in" the missing record for
the location of interest.
Fillip was used to estimate the (monthly) gains between the Yadkin College and the High Rock
gages (herein referred to as "High Rock gains") and between the High Rock and Rockingham gages
(herein referred to as "Rockingham gains") for the period when the gains were not known (1929 to
1941 and 1962 to 2003). The gains represent the difference between the flows atthese gages. Since
these gages are influenced by regulation, the flows were adjusted to reflect unregulated conditions
by adding back the known change in storage and estimated net evaporation from the upstream
reservoirs. The monthly High Rock gain is equal to the difference between the monthly unregulated
i Precipitation at Kerr Scott is based on ACOE measurements and, when not available (prior to July 1, 1965),
Salisbury station measurements.
z Evaporation is derived from monthly USGS measurements from Lake Michie in Durham, North Carolina (contained
in the report entitled Evaporation from Lake Michie, North Carolina, 1961-71, USGS Water Resources Investigation
38-73).
' For this latter period, which coincided with the operation of High Rock Reservoir, the USGS gage measured
regulated flows from the dam. Based on operating data, "total" flows into the reservoir were back calculated using
mass balance (inflow =outflow + change in storage + evaporation -precipitation).

No. 10. October 1983.

High Rock and Yadkin College flows. The monthly Rockingham gain is the difference between the
monthly unregulated Rockingham and High Rock flows.
Table B-6 presents the USGS gages that were evaluated in the unregulated hydrology dataset
development, along with their drainage areas and periods of record. Most of these gages have
records that overlap in part or in full with the known gains. The only gages that cannot be correlated
with High Rock are Second Creek, atributary ofthe South Yadkin and Abbott's Creek, atributary of
High Rock.

The output fromFillin consists ofthe correlation coefficients for each ofthe gages inthe table above
and the flow estimate for each month of the filled-in record. If needed, the Fillip-estimated High
Rock and Rockingham gains were adjusted to maintain consistency with the known gains between
the USGS gages at Yadkin College and Rockingham. The monthly High Rock inflows were
calculated by summing the adjusted High Rock gains to the Yadkin College flows.
The monthly High Rock inflows were disaggregated into daily flows using upstream gages. For
example, if the flow at the upstream gage(s) on the fifth of the month was three percent of the
monthly total, the daily High Rock flow was set at three percent of the monthly Fillip estimate.
Multiple gages, including the Yadkin College, Cooleemee, Mocksville, Hunting Creek, South Creek,
and Abbott's Creek gages were used in the daily disaggregation.
4.4.2.3 SubbasinRunoffCharacterisrics
As with most large watersheds, individual subbasins can have distinctively different runoff
characteristics, both in the timing and amount of seasonal runoff. This is especially true in the Pee
Dee River watershed, and these differing subbasin characteristics have significant effects on
hydrology, and therefore the operation of the Project. Most importantly, as described below, the
lower subbasins of the Pee Dee River (notably the Rocky and Little rivers) exhibit distinct
hydrologic differences from the upper subbasins (notably the Yadkin River above High Rock Dam)
characterized by the following:
B-36

Application for License Yadln~n-Pee Dee River Hydroelectric Project
^ Significantly lower monthly median flows during the dryer months of the year;
^ Lower runoff productivity as measured by runoff per square mile of drainage area, and
^ Greater flow variability as measured by the ratio of mean monthly to median monthly flows.
These differences have significant influence on the Project, especially when considering inflows to
the Blewett Falls Development. These considerations are discussed below.
subbasins within the Yadkin-Pee Dee watershed have differing runoff characteristics due to
orographic effects, land slope, soil type, surface type, and land use. The upper subbasins produce
more annual streamflow on acfs-per-square-mile basis than the lower subbasins, as demonstrated in
the USGS Water-Supply Paper #2403, "Low-Flow Characteristics of Streams in North Carolina",
1993. The report contains runoff information for various portions of the upper Yadkin-Pee Dee
River in terms of mean runoff per square mile of drainage area. Plate 2 of that report shows that
portions of the upper basin produce an average annual runoff of close to 2 cfs/min, while the lower
basin is closer to 1 cfs/min.
Another indication ofthese differing runoffcharacteristics is acomparison ofthe median annual and
monthly flows per square mile of drainage area The use of the median value removes the
significant skew to mean flows caused by brief (one to two-day) high flows in the subbasin as a
response to brief but intense rainstorms. As shown in Table B-7, the median daily August flow for
the upper basin as measured atthe Yadkin gage is 0.78 cfs/sm, while forthe same periodthe median
August daily flow for the Rocky River (a major tributary to the Blewett Falls Development) is 0.15
cfs/sm. By this measurement, the median upper basin flows are over 500 percent greater than the
median lower basin flows for the same period. Because of the very small active storage at Blewett
Falls, the mean monthly runoffvalues can be misleading as indicators of available flow. As shown
in Table B-7, the ratio of median to mean monthly flow in August for the Yadkin College gage
(upper watershed) is 0.73, while the same ratio for the Rocky River gage (lower watershed) is 0.28.
Mean monthly values are substantially influenced by high runoff events, the volume of which cannot
be captured in storage at Blewett Falls. Median flows are therefore a more reliable indicator of
available flows over a monthly period.
A duration analysis was performed to determine the differences in subbasin productivity.
Figure B-33 shows that the upper basin produces significantly more runoff per square mile except
during high-flow periods, attesting to the "flashiness" of the lower subbasins. Data on the Little
River, which also enters the Pee Dee River between the Tillery and Blewett Falls developments, is
provided in the figures as well.

4.4.2.4 Impact of Reservoir Storage on Annual Hydrograph
The Pee Dee River at the Rockingham gage was compared to other Southeast Atlantic basins to
illustrate the variation in seasonal flow patterns and to observe the overall effects of Pee Dee River
regulation on the shape of the annual hydrograph.
Figure B-34 shows a comparison between the Pee Dee River above Rockingham and various
regulated and unregulated «--Watersheds in the region. The more heavily regulated Roanoke River
shows the least variation between the early-spring high flows and summer/fall low flow periods,
while the uruegulated gages, such as the Rocky River and Little Pee Dee River show more variation
betl~~een spring and summer flows, and a more "flashy" nature. The flows for the Pee Dee River at
Rockingham track relatively closely to the runotTpattern ofthe unregulated systems, having a large
difference between the spring peak flows and the late summer minimum flows.

4.4.2.5 Hydratalrc Cor~nectivrty
Dec
Since the issuance of the Initial Consultation Document (ICD) {February 20(J3) and Joint Public
fleeting (March 2003) for the Yadkin-Pee Dee Project relicensing, Progress Energy worked closely
with stakeholders to identify needed studies and potential resource impacts due to the operation of
the Tillery and Blewett Falls developments. As a result of the consultation efforts with various
Resource Working Groups (RWG), Progress Energy agreed to perform a study to evaluate whether
the operation of the Project impacted floodplain habitats downstream of the Blewett Falls
Development. The specific concern focused on the Blewett Falls Development discharge capacity
and the potential for inundation of do~~mstream floodplains during periods of on-peak generation.
The potential for inundation was studied and a letter report was prepared and presented to the RWG
that concluded that there is no inundation of floodplain habitat as a result of Project peaking
operations. This report is attached in Appendix B of this Application for License and further
discussed below.
This issue was raised by the RWG as a result of knowledge of inundation issues identified by the
relicensing of the Roanoke Rapids and Gaston Hydropower Project on the Roanoke River (FERC
No. 2009) where the Roanoke Project peaking operation often resulted in the inundation of
do«~nstream floodplains. Members of the RWG were familiar with this issue and questioned if it
«~~ould be an issue on the lower Pee Dee River. Progress Energy agreed to perform the above-
referenced study.
To assure that areas were addressed by this study where inundation potential was highest, members
of the RWG and the relicensing team visited the lower Pee Dee River and located seven overbank
areas judged to be most susceptible to inundation. Those areas were subsequently field sun~eyed.

Hydraulic analyses of the lower Pee Dee River below the Blewett Falls Development were
performed usingfield survey data, USGS gage data, rating curves, and hydraulic models. The data
was based on the field survey of the seven transects of interest and combining that information with
the field datafrom 28 instream flow incremental method (IFIM) transects, five flow study transects,
three USGS gage sections, and a 1973 ACOE Navigation Study. The analyses compare the bankfull
discharge capacity at the various low-overbank locations to the Blewett Falls Developments
maximum discharge capacity.
The results of the analyses indicate that overbank flows in the Pee Dee River below Blewett Falls
Dam are unlikely to occur at flows below about 11,500 cfs. Since the Blewett Falls maximum
hydraulic capacity is 9,200 cfs, peaking flows at Blewett Falls (even without considering attenuation
of the unsteady state peaking flows) would be contained within the natural channel and do not
influence floodplain habitats. Further, Blewett Falls reverts to arun-of--river facility at river flows
exceeding the best-gate capacity of the six units, or 7,200 cfs, considerably less then the full gate
capacity of 9,200 cfs.

Progress Energy developed an operations model to evaluate the effectiveness of its current resource
utilization and assess alternative scenarios for use of the available water resource within the context
of current and potential future operations. The operations model developed required the input of
plant operating data, flo~~~ data, reservoir storage curves, turbine-generator efficiencies, and
operating guidelines defining flow priorities. The data, model, and evaluations are described below.

The gross (usable plus unusable) storage capacity of Tillery Reservoir is approximately
134,300 ac-ft at the normal reservoir elevation of 277.3 ft. The usable storage based on the current
licensed minimum pool elevation of 255.3 ft (a 22-ft dra«-down) is 84,150 ac-ft. The usable storage
of Tillery Reservoir based on a 4-ft operating band fi•oin elevation 277.3 to 273.8 ft is 19,000 ac-ft.
The gross storage capacity of Blewett Falls Reservoir is approximately 30,100 ac-ft at the normal
reservoir elevation of 177.2 ft. The usable storage based on the existing FERC-licensed minimum
pool elevation of 160.2 ft (a 17-ft drawdown) is approximately 24,000 ac-ft. The usable storage of
Blewett Falls Reservoir based on a 6-ft operating band from elevation 177.2 to 171.2 ft is
12,500 ac-ft. The 4-ft operating band usable storage is 9,100 ac-ft.
5.1.2 Operating "Rule Curves"
Reservoir "rule curves" do not apply to the operation of the Tillery and Blewett Falls developments
because neither facility has adequate storage capacityr to provide more then daily to weekly water
storage. Neither the Tillery nor the Blewett reservoirs have an annual, seasonal or monthly
dra«~down cycle ~~~hich are typical operations «There a "rule curve" would normally be applied.
Progress Energy's Tillery and Blewett Falls Reservoirs are operated as run-of-ri~•~er with daily
pondage. The amount of daily fluctuation is dependent upon system load and the inflows received
from upstream hydroelectric projects. The daily fluctuation of the Tillery and Ble«-ett reservoirs is
typically less than 2 and 4 ft, respectively.
The Tillery development typically utilizes the usable storage in its upper 1 to LS ft to meet peak
daily and/orload-following demands. This corresponds to an operating range bet~~~een 277.3 and
275.8 ft. With a maximum turbine capacity of approximately 18,000 cfs, flog-~ releases from Tillery
are coordinated on a daily basis with operations at the Blewett Falls Development to prevent spill
since the Blewett Falls turbine hydraulic capacity of about 9,200 cfs is considerably smaller than
B-42

Application for License Yadkin-Pee Dee Raver Hydroelectric Project
Tillery's. Discharges from the Tillery Development are re-regulated at Blewett Falls on a daily basis
by using the limited usable storage capacity in Blewett reservoir.
When river flow exceeds the Ble«~ett Falls maximum hydraulic capacity of 9,200 cfs, the Blewett
plant can no longer exercise any control of river discharge below Blewett Falls Dam. In practice,
when average daily river flow exceeds about 7,200 cfs, the Ble~~-~ett plant reverts to a strict run-of-
river operation. When flows are over approximately 9,200 cfs, Blewett Falls is forced to spill.
5.1.3 Spillway and Tailwater Rating CuY-~~es
The spillway at Tillery Dam is comprised of 18 radial gates. Non-po«-~er flo«~s at Tillery can also be
released through abottom-drop trash gate. The spillway at Blewett Falls is an ungated, concrete
gravity ogee spilwway. Atop the concrete spillway are 4-ft-high flashboards and a short section of
2-ft flashboards. The spillway rating curves for each development are presented in Figures B-37 and
B-38. Tailwater rating curves for the Tillery and Blewett Falls developments are presented in
Figures B-3 9 and B-40.

Blewett ~'alls~
The Blewett Falls powerhouse contains six generating units, each served by a dedicated penstock.
The maximum hydraulic capacity of the units at the Blewett Falls plant is about 9,200 cfs. All of the
units are horizontal-shaft double-"camel back" turbines each controlled by a separate governor.
Units 1, 2, and 3 turbines are each rated at 5,350 hp, and Units 4, 5, and 6 turbines are each rated at
6,400 hp. Each of the turbines drives adirect-connected, indoor-type, horizontal-shaft generator.
Units 1, 2, and 3 generators are rated at 4,000 kVA, and Units 4, 5, and 6 at b,250 kti A. The
turbines discharge via steel conical draft tubes into a 900-ft-long tailrace channel which flows into
the Pee Dee River.
Figure B-44 summarizes turbine performance data for Blewett Falls Units 1 through 3, and

5.1.5 Dependable Capacity
Traditionally, the dependable capacity of a power plant has been defined as the electrical load-
carrying ability under adverse load and flow conditions. A project's dependable capacity is
frequently less than its installed capacity because the amount of water available may be relatively
low during the time periods applicable to determining the dependable capacity. Determining the

amount of generating capacity available in a selected historical period that is considered critical from
the standpoint of both electrical load and hydrologic conditions is one of the techniques that has
been used to establish the dependable capacity of a hydropower project.
Because the Project reservoirs do not follow an annual drawdown and fill cycle, the dependable
capacity was based on the average capacity available in a high-load month. The month of
September has historically experienced the lowest monthly flows during the study period as
indicated in Figure B-30. The average historical net generation at the Tillery plant duringthe month
of September is 10,218 MZ~4~h. By this method, the dependable capacity for the Tillery plant is
14.2 ~iw. The Blewett Falls plant has a dependable capacity of 9.8 MW based on an average
historical net generation of 7,027 MWh
5.1.6 Plant Capability vs Head
The plant. generating capability is the plant output over a range of net head with the maximum
turbine discharge. The estimated maximum plant output at the Tillery Development is
approximately 84 Mtn' (generator limited) with all units discharging at their maximum limit with a
net head of 70 ft. The overall relationship between plant capability and net head is illustrated in
Figure B-46 for the Tillery Development.

5.1.8 Plant Factor
The average annual plant factors for the Tillery and Blewett Falls developments from 1984 to 2003

5.2 Operations Modeling
Progress Energy developed acomputer-based plant operations model to simulate existing Project
operations and evaluate potential future alternative operating scenarios. Because ofthe dependency
of Progress Energy's plants on the delivery of flows from upstream hydro projects, Progress Energy
elected to develop an operations model which included the entire Yadkin and Pee Dee rivers from
High Rock reservoir to Blewett Falls Dam. In addition to the operations model, Progress Energy
also developed an unsteady flow model to simulate the effect of peaking operations at Blewett Falls
Dam on flows in South Carolina. Peaking flows released at Blewett Falls are substantially
attenuated as they travel downstream. The Pee Dee River channel downstream of Blewett Falls is a
wide, low-gradient stream which results in fairly rapid attenuation ofthe peaking flows discharged at
Blewett Falls. By combining the plant operations model with the unsteady flow model, Progress
Energy developed a single model extending from the inflow to High Rock Reservoir to the USGS
gage at Pee Dee, South Carolina. This model was used to evaluate a range of future operating
scenarios by comparing the energy generation and plant outflows of future options to existing
conditions.
5.3 Proposed Future Resource Utilization
Since the issuance of the ICD (February 2003) and Joint Public Meeting (March 2003) for the
Yadkin-Pee Dee Project relicensing, Progress Energy has undertaken an extensive consultation
process, including completion of study plans and field studies consistent with an Enhanced
Traditional Licensing Process. Progress Energy issued its ICD for relicensing the Yadkin-Pee Dee
River Project in February 2003. At the Joint Meeting held in March 2003, Progress Energy
presented an overview of the Project, reviewed information provided in the ICD, and provided an
opportunity for stakeholders and the public to comment on the ICD and to identify concerns and
issues related to Project operations and the Project's effects on resources.
Progress Energy also used the Joint Meeting to invite resource agencies, interested parties and
members of the public to further participate in the relicensing process by being involved with one or
B-52

Application for License Yadln~n-Pee Dee River Hydroelectric Project
more RWGs. The purpose of the RWGs was to provide an opportunity for stakeholders to be
involved in the review and discussion of existing data, identification of resource issues,
identification of needed studies and review of study plans.
Draft study plans were prepared by Progress Energy for those issues which required additional
information and study. The RWG reviewed the draft study plans and provided comments. The
process resulted in the development of an agreed-upon set of final study plans that were issued in
January 2004 (Progress Energy 2004a). Copies of these study plans are included in Appendix A of
this License Application. Progress Energy proceeded to perform the identified studies in 2004 and
2005.
As a result of the extensive consultation efforts and detailed analyses of study results, Progress
Energy has developed its preferred plan forthe operation and maintenance ofthe Project in the next
license term (Preferred Plan). The Preferred Plan is founded on a balancing of environmental and
energy resources associated with the Project. This plan of future operations is described below and
compared to existing conditions. The Preferred Plan represents a future operating plan that
incorporates changes to current reservoir management and currentflow release requirements at both
developments. Progress Energy's proposed plan assumes, and depends upon, changes in the daily
discharge requirements from APGI.
Existing operational conditions required by the current FERC license are summarized in Table B-15.
Table B-15 Existing conditions.

Allowable Current Practice

1 The current FERC license allows a drawdown of 17 ft; however, intake submergence problems limit this drawdown
tollft
Progress Energy's Preferred Plan for future Project operations related to continuous releases and
reservoir fluctuations is summarized below in Table B-16. This Preferred Plan established an
appropriate balance between power and non-power resources based upon the consultation and
studies conducted as part of the relicensing process.

BlewettFallsLake 150 975/2,000' n/a 1,200/2,400' 1T 2.0/6.0/8.0'
1 All proposed minimum flows are based upon the assumption that average daily flow deliveries from APGI under the
new license would be 1,000 cfs from May 16 to January 31 and 2,000 cfs from February 1 to May 15.
z Lake Tillery minimum release is 200 cfs year round except for April 1 to May 15 when minimum release is 750 cfs
(starting in 2013 in association with the Diadromous Fish Restoration Plan [see Exhibit E4]).
3 Blewett Falls minimum continuous release is 975 cfs from May 16 to January 31 with 1,200 cfs minimum average
daily and 2,000 cfs continuous from February 1 to May 15 with 2,400 cfs minimum average daily flow.
B-53

Application for License Yadkin-Pee Dee River Hydroelectric Project
4 All reservoir fluctuation limits are set as targets; maintenance of minimum flows has priority over lake elevations.
5 R~Iaximum drawdown allowed under the current license. Actual fluctuations by voluntary action of Progress Energy
are 6 to 8 ft at Blewett and 4 ft at Tillery.
s Lake Tillery Reservoir fluctuation limits consist of 1.0-ft limit of fluctuation from April 15 to May 15; 1.5 ft on
weekends and 3.0 ft on weekdays, except from December 15 to March 1 when the allowable fluctuation is 5 ft.
Maintenance drawdown of 10 to 12 ft once in five years.
~ Blewett Falls Lake reservoir fluctuation limits consist of 2.0 ft during bass spawning season; 6.0 ft year round; and
8.0 ft when flashboards are down.
The continuous releases proposed under the Preferred Plan substantially improve conditions for
aquatic species in the river reaches below Tillery and Blewett Falls as described in detail in
Exhibit E-4. X11 minimum continuous releases proposed for the Tillery and Blewett Falls
developments would be presumed to have been met if flows are recorded to be within five percent of
the required minimum. The enhancement to aquatic species also results in a significant reduction in
hydro generation especially on-peak generation. Tables B-17 and B-18 show the simulated energy
production for the 1983 to 2003 period for both existing and proposed future conditions,
respectively, based on the hydrology dataset developed as described in Section 4.3.2.5. Based on the
operations model, the Project's on-peak energy production under existing conditions averages
268,200 MWh/yr. Under the proposed future operations, this is reduced to 253,190 MWh, about a
six percent loss.

Due to the increased minimum flows at Tillery (500 percent increase) and Blewett Falls (650 percent
increase), critical on-peak energy production is reduced at Tillery by 5.5 percent and at Blewett Falls
by 5.8 percent. This lost load-following ability and on-peak energy generation will have to be made
up by fossil-fuel sources, probably combustion turbines. In Progress Energy's service area, on-peak

generation is of much greater value than off-peak generation, and in fact, ofd peak generation can at
times have no value at all {because base load units output can exceed demand in off-peak periods).

Tables B-19 and B-20 present flow duration data at outflow from the Blewett Falls Development
under both the proposed and existing conditions. Comparing streamflows or the existing and
proposed future conditions shows a substantial enhancement of flows downstream of Blewett Falls
dam «~hich results in enhanced flo~~~s in the entire reach of the Pee Dee River in South Carolina.
5.4 Assessment of Other Project Improvements
Initial evaluations were made regarding the possibility of rehabilitating the Blewett Falls
powerhouse and modernizing the existing equipment at the Tillery Development. Based on the
results of the analysis completed by Progress Energy, neither of these upgrades are feasible at this
time.
Progress Energy has developed a Dissolved Oxygen (DO) Enhancement program to address state
water quality standards at the Tillery and Blewett Falls developments. Compliance with DO
standards are to be met within three years of issuance of the ne«~ FERC license. Progress Energy
proposes to complete field testing of options by December 2008 and to complete successful
implementation by December 2011. If this on-going effort results in any substantial modif°ications to
the existing developments, Progress Energy will submit revised Exhibit F drawings to FERC for
review and approval. The DO Enhancement Plan is more fully described in Exhibit E3.

Relatedto diadromous fish, Progress Energy, in consultation with resource agencies, has proposed a
Diadromous Fish Protection and Passage Plan thatwill consist of a phased approach to diadromous
fish enhancements based on a multi-year program to be implemented during the term of the next
license period. This plan is consistent with the goals and objectives of the Pee Dee River
Diadromous Fish Restoration Plan prepared by resource agencies. Implementation ofthis plan will
result in changes to project facilities (e.g., construction of upstream fish passage facilities) and
operations (e.g., diverting flow through fishways). Progress Energy's Diadromous Fish Plan is
described in Exhibit E4.
5.4.1 Recreation Enhancements
Progress Energy proposes recreational protection, mitigation, and enhancement (PM&E) measures
for the Tillery and Blewett Falls developments that will provide the public with additional access
and recreational opportunities atthe Project duringthe next license term. The issue of overcrowding
at public access areas was not generally perceived as an issue of concern by recreational users
visiting facilities at either of the Project lakes. Issues identified by recreational users were related
more towards misuse of the facilities and less towards boater use levels.
Tillery Development
Progress Energy proposes to make several improvements atfour public boating access areas located
on Lake Tillery: the Lilly's Bridge, Swift Island, Norwood, and Stony Mountain access areas.
Generally, improvements to these areas include the addition of public sanitary facilities, trash
receptacles, improved structured parking areas, additional public information signage, and updating
the Project public information kiosks.
Progress Energy proposes to close the existing informal public boating access area located in the
tailrace immediately below the Tillery Plant. Progress Energy, in consultation and partnership with
the NCWRC, will develop and construct a new public boating access area located at the mouth of
Clarks Creek, approximately one-half mile below the power plant and one-quarter mile from the
current access area. Public access to the Clarks Creek boating access area will be from the power
plant access road (i.e., Tillery Dam Road) which is located off State Road 1103 and N.C. Highway
731. The boating access area will have a formal, structured gravel parking lot with designated
Americans with Disabilities Act (ADA) parking places.
Progress Energy proposes to work with the NCWRC in co-funding with matching dollars for the
construction of a boat house and access ramp for use by enforcement personnel on Lake Tillery.
This facility will permitthe NCWRC to respond more effectively to boating emergencies on the lake
and serve as a central point for safe boating enforcement activities on the lake. The proposed
location is on the main lake side of the Project lands on the peninsula located adjacentto and south
of the Stony Mountain boating access area. Progress Energy will consult with the NCWRC on
effective means to discourage public use ofthe informal public access area at State Roads 1740 and
1745, locally known as the Steel Bridge Area. The development of the public fishing pier at the
nearby Stony Mountain boating access areawill provide additional public fishing opportunities that
may be eliminated with the closure of this informal access area.

Blewett Falls Development
Progress Energy proposes to build anew public boating access area on the Richmond County side of
Blewett Falls Lake within five years of issuance of the new license. The new boating access area
will be located in the lower lake area in the general vicinity of the existing Pee Dee access area
which is located on the Anson County side of the lake. Progress Energy will workwith local county
officials and interested landowners to site the new public boating access area, and with NCWRC on
design specifications and construction details.
Progress Energy proposes to include several improvements at the two public boating access areas
located on Blewett Falls Lake, which are the Pee Dee and Mountain Creek (Grassy Islands) access
areas. Atthe Pee Dee Access Area, Progress Energy will provide public sanitary facilities and trash
receptacles; update the public information signage including a new Project information kiosk; and
improve parking facilities for vehicles and boat trailers. At the Mountain Creek (Grassy Islands)
Access Area, Progress Energy will provide trash receptacles; update the public information signage
including a new Project information kiosk; and improve parking facilities for vehicles and boat
trailers. At both sites, Progress Energy will also workwith the NCWRC to improve the boat ramps
which permit effective boating accessibility over the range of lake levels proposed for the new
license term.
Progress Energy proposes to upgrade the canoe portage facility located on the east shoreline of
Blewett Falls Lake at the dam to applicable state recreational standards. Progress Energy will
provide an electronic link on its external Company Internet web site that will allow the public to
access real-time Pee Dee River stream flow data at the USGS Rockingham gage station (USGS
Gage No. 02129000). This stream flow information can be used to plan boating recreational
activities for the Pee Dee River located below the Blewett Falls Hydroelectric Plant.
5.4.2 Other Enhancement Measures
Lake Tillery
Progress Energy submitted a Shoreline Management Plan (SMP) for Lake Tillery to FERC on
December 28, 2001. The SMP was approved by FERC, with modifications, on November 24, 2004.
Progress Energy intends to fully implement the Tillery SMP over the term of the neat license.
Subsequent to consultation performed during the relicensing process, Progress Energy agreed to
develop a Historic Properties Management Plan (HPMP). Progress Energy has been consulting with
the North Carolina State Historic Preservation Office (SHPO), the Catawba Indian Nation, and other
interested parties, on the development of the HPMP. Following issuance of the new license,
Progress Energy will finalize, seek approval from FERC, and fully implement the HPMP.
Progress Energy will coordinate with the USFWS' Pee Dee River NWR for purposes of providing
flows when filling of refuge ponds. Progress Energy will initiate coordination following issuance of
the new license from FERC.

Blewett Falls Lake
Yadlnn-Pee Dee River Hydroelectric Project
Progress Energy will adopt a shoreline management policy that prohibits private access to the lake
across Project lands except at designated public access areas in orderto protectthe existing character
and natural resources along Blewett Falls Lake. This management policy (when approved by FERC)
will reflect all relevant license requirements of the new license, and consequently, will be formally
adopted after FERC has issued the new license for the Project.
Progress Energy will repeat the lake sediment survey in Blewett Falls Lake and gravel recruitment
survey in the Pee Dee River downstream of the Blewett Falls dam within five years of license
issuance in orderto reevaluate Project conditions at that time. Ifresults continue to indicate that no
significant problem exists, Progress Energy will conduct another survey after an additional 10 years.

Yadkin-Pee Dee Reservoir Management/Hydrologic Model
Modeling Criteria
Cun ently there is no model available to assess basinwide impacts of existing and future water withdrawals on
the project reservoirs and the impacts of reservoir operations on water resources. There needs to be a single
basinwide hydrologic model that covers the basin from Georgetown, SC upstream to the headwaters. The
model needs to include all withdrawals and discharges of 100,000 gpd or greater and all water supply and
hydroelectric reservoirs. In addition to the basic hydrology and reservoir manzgement, additional issues such
as the following need to be studied: salinity, water quality, and instream flow. Depending upon the model
selected to study these other issues the reservoir managementlhydrology model may need to function as apre-
or post-processor. For example, a salinity response model of the tidally influenced areas of the Pee Dee River
is needed to understand the effects of salinity on surface water intakes and aquatic biota in coastal SC. The
reservoir management/hydrology model will simulate the flows and then that flow data set can be used in the
salinity response model to determine if there are changes in the salinity profiles. The model goals,
requirements, and examples of output that follow are for the reservoir management/hydrology model and do
not include the requirements for the salinity, water quality, and instream flow models.
Examples of typical impact analysis and performance criteria such a model would be used for include:
• Impacts to lake recreation. A summary by reservoir of how many boat ramps and swimming beaches
are closed or unusable: total days, days per year, and how many years a ramp is closed at least for
more days during the recreation season.
• Impacts on lake waterfowl hunting. A summary by reservoir of how often lake levels will impact
hunting: how many days, days per year, and how many years.
• Impacts on fish spawning in the lakes. A summary of daily lake level changes and how often
spawning is impacted for identified critical spawning periods.
• Impacts to water supply withdrawals, for both run-of--river intakes and reservoir withdrawals.
Demand satisfaction for the current conditions and 50-year projected demands.
• Impacts to low-flow/minimum release targets. How often is the target not satisfied?
• Changes in stream flow at any node. This includes changes in the duration curve and parameters such
as the 7Q1O.
• Characterize hourly and 15 minute changes in flow and stage at sites chosen for instream-flow
studies.
• Impacts to hydroelectric generation.

Goals & Objectives of the Reservoirs Management/Hydrologic Model
The goal is the development of a single basin model that will meet the needs for both relicensing and for long-
term management decision-making. This effort must result in a surface water quantity and reservoir
management tool, which can be accepted as the primary tool for evaluating current and future uses of the
surface waters of the Yadkin-Pee Dee River Basin. Since this model will be used for significant decision-
making tool, the model must be developed in an open, cooperative manner and be subject to scrutiny by all
interested parties. The resulting model must be a generally accepted analytical tool that can be widely used to
develop consensus among the numerous stakeholders in the basin. Users must be able to evaluate a variety of
"what-if' scenarios that will provide insight into impacts relating to power generation, downstream flows for
wastewater assimilation, water supply availability, instream uses, and recreational lake levels, for example.
While this model need not include water quality or habitat analysis directly, the steamflow output data from
this model must be capable of being used as input or flow calibration data to the water quality models
currently approved by the States of NC and SC. Water quality effects will be important in evaluating the
impacts of proposed operational changes.
Model Requirements
The model will geographically cover the entire Yadkin-Pee Dee River Basin from the headwaters down to the
most downstream water supply intake in Georgetown, SC. The model needs to have auser-friendly interface
and incorporate seasonally varying withdrawal and discharge information of 100,000 gpd or larger. It needs
to incorporate annually varying water consumption from agricultural use based on climatic conditions during
growing season. The model needs have the capability to allow for stream flow analysis, drought management
planning and forecasting. In addition the model will have the capability to incorporate alternative drought
management policies. Basic model documentation and training needs to be provided to users of the finished
model.
The data needed for the modeling will include, but not be limited to, the following:
Inflows: Wherever possible, the model must use actual historical streamflow, precipitation, and
evaporation records corresponding to the same historical time step. A hydrologic period of record of
at least 75 years or longer must be used where data are available. The period of record used in the
model must include the drought of the early 1930's and 2002. This will require the adjustment of gage
flow data in order to generate unimpaired flows. Synthetic generation of inflows will be necessary at
some locations where historic records are shorter than the period of record used in for the model. At
a minimum, the adjustment of gage flow data must include historical adjustments for regulation,
consumptive uses, net evaporation, and transfers in order to generate ununpaired flows.
Data on consumptive water use, discharges, transfers, evaporation and precipitation must be prepared
for the same period of record as that used for streamflows.
Reservoir data and operation: The model must incorporate the current operating policies for APGI's
and Progress Energy's reservoirs and other significant impoundments, such as W. Kerr Scott
Reservoir. Data needed will include, but not be limited to, flow ratings of hydraulic outlets, turbine
rating curves, seasonal low flow targets downstream, seasonal water withdrawals and return flows,
stage-storage-surface area information, discharge-stage relationships of flood control points
downstream and interactions between the impoundments being modeled.
Required instream flows: Information regarding instream flows for river segments must be included.
These flow requirements may vary monthly or seasonally.

June 25. 2003
The basic objectives and output requirements of the model are as follows_
(1) The model must be amass-balance simulation model that will emulate the operation of the reservoirs
of interest and flow conditions for major stream segments for the Yadkin-Pee Dee River Basin for the
full range of flows in the hydrologic record.
(2) The model must be capable of displaying a schematic basin map showing locations of all model
nodes. ArcView is a preferred method for displaying geographic information.
(3) Default model conditions must correspond to existing withdrawal and discharge conditions, and these
withdrawal and discharge levels must be allowed to vary for each individual time step of simulation
period. Withdrawals and discharges for each user must be simulated as a system with the capability to
have multiple withdrawals and discharges for a single user. The system demand needs to be able to
include ground water, water purchases, and interbasin transfers. The model needs to be able to
account for multiple withdrawals and discharges at the same node and/or reservoir from different
users. Model must also be flexible enough and sufficiently documented to allow simulation of user-
defined withdrawal and/or discharge levels at any point on the river (probably defined by river mile}
or lakes, which differ from existing conditions.
(4) The model must be able to simulate the existing and future operating policies for the reservoirs.
Default model conditions must correspond to existing reservoir operating policies. The model must
also be flexible enough and sufficiently documented to allow simulation and display ofuser-defined
reservoir operating policies, that differ from existing conditions (e.g., reservoir storage allocation,
reservoir releases, new or revised low-flow targets, etc.)
(5) The model shall track low flow targets downstream that can vary seasonally. The model must be
capable to begin simulation with user-defined reservoir storage volumes, which maybe less than 100
percent.
(6) The model must be able to run on a daily time step and be able to run for periods of one year up to the
total number of years in the record. Users must be able to specify these parameters from simple menu
screens. From these screens, users must also be able to specify additional withdrawals and discharges
for specific model nodes.
(7) Model runs must generate time-series outputs. The time series outputs should be available in table
format for ready export into water quality models, spreadsheets, or other tools used by NC and SC.
(8) The model must be capable of displaying system variables in an input/output layer to facilitate
inspection of key model parameters and performance of sensitivity analyses.
(9) The model must be capable of displaying a history of river flow conditions at all selected model
nodes during the simulation period for all the major stream/river segments.
(10) The model must be capable of displaying a history of water elevation, surface area, storage volume,
power generation, and water balance information in any modeled reservoir over the simulation period.
This also includes annual summary tables of maximum and minimum lake levels, etc.
(11) The model must be capable of producing streamflow output data for use as input data or as flow
calibration data to water quality models currently approved by both States. It must be capable of
producing such stream flow profiles for a variety of flow scenarios including 7Q 10/drought
conditions.

NC Modeling Criteria.doc

June 25, 2003
(12) The model must be capable of producing flow output data suitable to establish boundary conditions
for hydrodynamic, water quality and water quantity models of the tidally influenced portion of the
river, in the event that such models are developed.
(13) The model must be capable of supporting drought management planning and forecasting. Specific
drought evaluation techniques which the model must be capable of performing include: safe yield
estimation for river withdrawals; tracking user-defined minimum instream flow targets at individual
model nodes, flow targets must be allowed to vary by time step; and evaluating water supply benefits
from conservation scenarios. The ability to input conservation measures by water users need only
have the form of thresholds (flow or pool volume, for example) and associated percentage reductions
in water use.
(14) The model needs to have nodes at all withdrawals and discharges of 100,000 gpd or greater, all
water supply and hydroelectric reservoirs, all instream flow study sites, and additional nodes for
water quality purposes as needed. The model must be flexible enough and sufficiently documented to
allow addition of new model nodes for new withdrawals, discharges, or stream flow evaluation
points. Nodes must not be hard-coded such that program modification is required to add or delete
nodes. The model must have the ability to have nodes added and different operating policies be used
without having to modify and recompile the model for each change.
(15) The model should incorporate annually varying water consumption for agricultural uses based on
climatic conditions during growing season.
(16) To promote accessibility and usability, the model must be user fi-iendly and written for the PC
environment, and be available on CD-ROM or downloadable from Internet. An application needs to
be built for the Windows (2000/XP} environment. This model will be available as public domain
software. This requires that appropriate licensing arrangements be made with any owner of
proprietary software shipped with the model. For practicality, the run-time for a daily time step run
for the entire period-of-record must not exceed I S minutes for the full period of record base case
simulation.
(17) A detailed document describing the data set preparation and model formulation and a detailed user's
manual, adequate for use by less technical staff, and training needs to be provided.

EMERGENCY DROUGHT MANAGEMENT PROTOCOL
FORPOST-SEPTEMBER 15 OPERATIONS
Parties. This protocol is entered into by Alcoa Power Generating Inc. ("APGI"),
Carolina Power 8c Light Company ("CP&L"), North Carolina Department of the
Environment and Natural Resources ("NCDI3NR"), South Carolina Department of
Natural Resources ("SCDNR") and South Carolina Department of Health and
Environmental Control ("SCDHBC")(collectively, "the Parties").
2. Background. The Parties are entering into this protocol because of the continuation of
the drought of unprecedented severity in the region that contains the Yadkin-Pee Dee
River basin. Some of the factors that have led to this protocol are the following:
• North Carolina and South Carolina have experienced drought conditions
since June 1998, the longest and most severe drought since hydrologic
records have been kept. Groundwater levels in both North and 5auth
Carolina are declining at an accelerated rate and dry wells are occurring in
both states. The Yadkin-Pee Dee River watershed is in the exceptional
drought classification, the most serious, category. The Yadkin River
portion of the basin has been in the exceptional drought classification
since June 18, 2002. The can ent forecast through November 2002 shows
the drought in this region is likely to persist. Normal or above rainfall is
forecast for moat of South Carolina and coastal North Carolina in
December2002-February 2003 and possibly into the spring of 2003 due to
the presence of a weak to moderate Ei Nino. This should bring some
relief, but it may not end the drought.

The entire northern coast of South Carolina from Little River, near the
State line, to the City of Georgetown depends on the Pee Dee River for
their water supply. Included are the Cities of Myrtle Beach, North Myrtle
Beach, Conway, Loris, Suttside Beach, snd Georgetown, the towns and
communities of Little River, Socastee, Aynor, Wampee, Garden City,
Muaelis Inlet, Litchfield Beach, Pawleys Island and Debidue Beach and
unincorporated areas of Hoary and Georgetown Counties. These areas are
served by four water treatment plants: Myrtle Beach, Grand Strand Water
and Sewer, City of Georgetown, and Georgetown County - Waccamaw
Neck. inland from the coast, the City of Cheraw draws ate water from the
Pee Dee River. Together these serve ayear-mend population of 275,000.
With the Grand Strand area being a major tourist destination, the summer
population easily exceeds half a million people.
• The Georgetown County plant has already experienced numerous
occasions since last October when the saltwater intension elevated chloride
levels beyond the EPA secondary standard of 2S0 mg/1, and it had to cease
operations. Georgetown County has been relying on wells that are high in
fluoride and sodium and is purchasing some treated water fmm the Grand
Strand Water Plant in older to maintain its system during the shutdowns.
Six North Carolina public water supply systems withdraw water fmm the
hydroelectric reservoirs on the Yadkin-Pot Dee River in North Carolina.
These public water systems are at risk as the prolonged drought has
reduced inflows and put the reservoirs under stress as water is released to
meet downstream flow requirements, which are substantially greeter than
inflows. The North Carolina water supply systems involved are:

in the Yadkin-Pee Dee River basin, there is one public water system in an
emergency status, l5 under mandatory conservation and 19 under
voluntary conservation. There are 70 public water systems in the basin and
all but four of the systems have their water source in a threatened or highly
vulnerable status.
The best computes model and information available indicates that during
this drought period s daily average flow of 900 cubic feet per second
("cfa") at the Rockingham, North Carolina, USGS gage, should maintain
the saltwater front at a close but safe distance from the Grand Strand
Water Plant's intake on Bull Creek, a water course connecting the Pee Dee
River with the Waceamaw River. Since the Grand Strand Plant, in
addition to sugplying its own customer base, serves as the backup for
Georgetown County, Myrtle Beach and North Myrtle Beach, shutting this
intake down would cause hundreds of thousands of people to be out of
water.
3. Pmrpose. The purpose of this protocol is to adopt special management measures for the
Yadkin-Pee Dee River basin to respond to the unprecedented drought conditions for the
protection of public health and safety. Temporary envisions in normal operating policies
are needed to reduce the risk to public water supplies in North and South Carolina end to
minimize envinmmental and economic damage being caused by the drought in the
reservoirs and rivers of the Yadkin Pee Dee watershed.
4. Term And Release Target. After September I5, 2002, and until the Parties agree that
the drought emergency has passed or March 6, 2003, whichever comes first, the dams
and reservoirs of the Yadkin-Pee Dee River basin owned by APGI and CP&I, will be
operated so as to achieve sufficient flows in the Pee Dee River to prevent salt water
intrusion into the water intakes of public water suppliers in South Carolina, subject to
conditions described below. The initial target for such flows as measured at the
Rockingham, North Carolina, USGS gaga, subject to revision by a consensus among the
Parties, shall be 900 cfs daily average. The target may be revised based on South
Carolina's monitoring of the salt-water movement and other environmental indicators. If
the flows in the Pee Dee River as measured at Pee Dee, South Carolina or some other
Page 3 of 6
Appendix B-2 - 3

Application for License
Yadlan-Pee Dee River Hydroelectric Project
downstream USGS gage are sufficient as agreed upon by the Parties, then the 900 cfs
target at Rockingham maybe adjusted.
Reservoir Drawdown Limits. Subject to operational and environmental considerations,
nne goal will be a proportional drawdown of the AFGI and CF&L reservoirs (fi'igh Rock,
Tuckertown, Narrows (Badin), Falls, Tillery and Blewett Falls) to minimize drought
impacts and equalize the burden on reservoir users and on fish and wildlife. Because of
fish kills experienced during this summer, an interim objective will be to raise High Rock
Reservoir to a level of 17 feet below normal full pool while other reservoirs on the basin
are drawn down proportionately. To that end, Parties have agreed that, at a minimum, it
is prudent to plan on having an initial (ticr 1) drawdown limit for each of the reservoirs as
set forth below:
eservoir Down From Normal N~II Pool. feet
High Rock 17.0
Tuckertown 3.0
Narrows {Badin} 22.0
Falls 5.0
Tillery 4.0
Blewett Falls 2.0
)f the drought continuos as forecasts now predict, in order to fulfill the purpose of this
protocol it may be necessary to consider further reservoir drawdowns. Before the
reservoirs are drawn down below the levels shown in the above table, the Parties will
have worked together constructively to arrive at a consensus regarding increased water
conservation measures for water withdrawals and reduction of the Rockingham release
target, giving due consideration to operating constraints end with the intent of minimizing
the overall environmental and economic harm. The following table states a second tier of
further drawdown limits:
Reservoir Down From Normal Full Pool feet
High Rock 24.0
Tuckertown 3.0
Narrows (Bailin) 25.0
Falls 5.0
De... d ..f !.
Appendix B-2 - 4

Tillery 10.0
Blewett Falls 6.0
In the event that the droughtcontinues, the Parties will continue to work together
collaboratively as described above io meet the public health emergency created by the
drought.
6. Reservoir Reflll. An explicit goal of this protocol will be to manage the storage in the
APGI and CP&L reservoirs in a conservative manner, taking into account the possibility
that the drought could extend past March 5, 2003. In recogniflon of that possibility, the
Parties recognize that it is in their wllective interest to refill the reservoirs as soon as
reasonably possible, and that such reservoir refill will require that outflows are less than
the total inflow into the six reservoirs during the refill period. During the refill period
South Carolina may request a flow as measured at the Rockingham, North Carolina,
USGS gage greater than 900 cfs or the cunt target, for the purpose of industrial
wastewater assimilation, and, if all Parties agree, the target maybe adjusted. The larger
releases will depend upon current and projected river flows, inflows into the reservoirs,
reservoir levels, and time of the year.
7. Public Communications. The Parties will cooperate with each other in communicating
with the public regarding actions under this protocol. Such public communications will
include periodic and as needed actual information and forecasts relating to operations of
APGI and CP&L facilities, reservoir levels, strearnflows and rainfall.
8. Constraints. The commitments of APGI and CPBti. to maintain the flows set forth in
this protocol are subject to (a) the terms and conditions of their respective licenses under
the Federal Power Act as well as the authority of the Federal Energy Regulatory
Commission; (b) the operating constraints inherent in their facilities; and (c) their ability
to operate their respectve units without endangering persona or property. If (a) required
by operating emergencies beyond their control or on their respective. systems; (b)
required as a result of unusual weather conditions; or (c) ordered to do so by the Federal
Energy Regulatory Commission, APGI and CP&L may also temporarily operate their
respective developments in a manner such that the reservoir levels and/or downstream
flows do not meet the targets specified herein.
4. Regulatory Approval. The Parties recognize that the ability of APGI and CPBcL to
respectively perform actions contemplated by this protocol may be constrained by or may
require the prior approval of regulatory authorities, including the Federal Energy
Regulatory Commission:
10. Continuing Management Adjustments The Parties recognize that the target reservoir
level drawdowns and releases are based on the best available information on current

2.0 Project Construction History
Progress Energy owns and operates the Yadkin-Pee Dee River Project (Project). The Project
consists of the 84 megawatt (MW) Tillery Development and the 24.6 MW Blewett Falls
Development located on the Yadkin and Pee Dee rivers at approximately river miles (RM) 218 and
188, respectively. Each development consists of a dam, powerhouse, impoundment, primary
transmission lines from the Project, structures used in connection with the Project, and water rights,
rights-of--way (ROW), lands, and interest in lands necessary for the operation and maintenance ofthe
Project.
The Blewett Falls and Tillery Developments were constructed in the early 1900s. Blewett Falls was
placed in operation in 1912, and the Tillery Development began operating in 1928. In 1958, the
Federal Power Commission, predecessor to the Federal Energy Regulatory Commission (FERC),
issued to Carolina Power & Light (CP&L) a 50-year license for the Yadkin-Pee Dee River Project
designated as FERC No. 2206.
The Tillery Dam and its powerhouse are located in Montgomery and Stanly counties, four miles
west of Mount Gilead, North Carolina. The Tillery impoundment (known as Lake Tillery) extends
approximately 16 miles upstream to the tailwater of Alcoa Power Generating, Inc.'s (APGI) Falls
Development. Construction of the Tillery Development commenced in 1926. It was placed in
service in 1928.
The Blewett Falls Dam and powerhouse are located in Anson and Richmond counties. The Blewett
Falls impoundment, also known as Blewett Falls Lake, extends approximately 11 miles upstream of
the dam. Construction of the Blewett Falls Development began in 1905. Financial problems
prevented the original builders from completing the Project. The Yadkin River Power Company
acquired the rights to the Blewett Falls Development and finally brought it into service in June 1912.
CP&L acquired the Yadkin Power Company in 1926. The Blewett Falls Dam and powerhouse are
located approximately 17 miles upstream of the North Carolina-South Carolina state line.
An overview of the history of Project improvements is summarized in Table C-1.

3.0 Description and Schedule of Proposed Project Improvements
3.1 Project Improvements to Generation
There are no proposed improvements to generating equipment. The primary mechanical and
electrical components are in good working condition. Certain improvements to the spillway section
of Blewett Falls are scheduled for 2008 and 2009.
3.2 Non-Power Improvements
Since the issuance of the Initial Consultation Document (ICD) (February 2003) and Joint Public
Meeting (March 2003), Progress Energy has completed a rigorous schedule of consultation, study
plan development and field studies consistent with the Enhanced Traditional Licensing Process.
Progress Energy published its ICD for relicensing the Yadkin-Pee Dee River Project in February
2003. At the Joint Meeting held in March 2003, Progress Energy presented an overview of the
Project; reviewed information provided in the ICD; provided an opportunity for resource agencies
and the public to comment on the ICD; and identified concerns and issues related to Project
operations and effects.
Progress Energy also used the Joint Meeting to invite resource agencies, interested parties, and
members of the public to further participate in the relicensing process by being involved with one or
more Resource Working Groups (RWG). The purpose ofthe RWGs was to provide an opportunity
for stakeholders to work cooperatively with Progress Energy on review and discussion of existing
data, identification of resource issues, identification of needed studies and their goals, review of
study plans, and review of study results. RWGs were established for four resource areas: 1) water
resources; 2) terrestrial resources; 3) recreation and land use; and 4) cultural resources.
Draft study plans were prepared by Progress Energy for those issues which required additional
information and study. The RWGs reviewed the draft study plans and provided comments. This
process resulted in the development of an agreed-upon set offinal study plans that were then issued
in January 2004 (Progress Energy 2004). Copies ofthese study plans are included in Appendix A of
this Final License Application. Progress Energy performed the agreed-upon studies in 2004 and
2005.
Progress Energy has developed a Preferred Plan for the future operation of the Project which
provides a reasonable balance between power and non-power resources. This balancing of resources
is described in the Executive Summary filed with this License Application. Specific aspects ofthis
Preferred Plan are discussed in the individual exhibits ofthis License Application. An overview of
the measures proposed by Progress Energy, and their schedule for implementation, are discussed
below.
3.2.1 Continuous Flow Releases and Reservoir Fluctuations
Progress Energy is planning to implement its proposed continuous instream flow releases and
reservoir fluctuation regimes upon issuance of the new license.
As a result of extensive instream flow studies and analyses completed as part of relicensing,
Progress Energy has developed in its Preferred Plan for future Project operations (Preferred Plan)
C-4

Application for License Yadln~n-Pee Dee River Hydroelectric Project
certain proposed changes to reservoir levels and continuous discharge requirements at both the
Tillery and Blewett Falls developments. This Preferred Plan assumes, and is dependent upon,
certain minimum daily discharge requirements being received by Progress Energy from APGI, the
owner and operator ofthe upstream Yadkin Project (FERC No. 219'x. Progress Energy's Preferred
Plan is based on the above-referenced consultation, research, field studies and findings conducted as
part of this relicensing and provided in Exhibit E of this License Application. The Preferred Plan
reflects an appropriate balance between resource protection and preservingthe critical on-peak and
load-following generation benefits of the Project.
Table C-2 summarizes flow and lake level aspects of the Preferred Plan.
Table C-2 Proposed operational conditions for the Yadkin-Pee Dee River Project
Proposed Operational Conditions
Development Minimum Instantaneous Minimum Average Reservoir Flugtuation
Flows Daily Flows Limas
Tillery Development 200/750` --- 1.0/1.5/3.0/5.0'
Blewett Falls Development 975/2,000' 1,200/2,400' 2.0/6.0/8.06
1 All minimum flows are based upon the assumption that average daily flow deliveries from APGI are 1,000 cfs from
May 16 to January 31 and 2,000 cfs from February 1 to May 15.
z Lake Tillery minimum release is 200 cfs year round except for April l to May 15 when the minimum release will be
750 cfs (starting in 2011 in association with the Diadramous Fish Passage Plan contained herein).
3 BlewettFalls minimum continuous release is 975 cfs from May 16 to January 31 with a 1,200 cfs minimum average
daily release during this period, and 2,000 cfs continuous release from February 1 to May 15 with 2,400 cfs
minimum average daily flow during that period.
4 All reservoir fluctuation limits are set as targets; maintenance of minimum flows has priority over lake elevations.
5 Lake Tillery reservoir fluctuation limits consist of 1.5 ft on weekends and 3.0 ft on weekdays, except from
December 15 to March 1 when the allowable drawdown is 5 ft and except from Apri115 to May 15 when the limit
will be 1 ftto enhance bass spawning. Maintenance drawdown of 10 to 12 ft anticipated once every five years.
5 BlewettFalls Lake reservoir fluctuation limits consist of 2.0 ft during largemouth bass spawning season; otherwise
6.0 ft year round; and 8.0 ft when flashboards are down.
For compliance monitoring of instream flows at the Tillery Development, Progress Energy proposes
to partner with the USGS to install a gaging station at the N.C. Highway 731 Bridge. Progress
Energy proposes to utilize the existing USGS Rockingham gage at the U.S. Highway 74 Bridge
(USGS Gage No. 02129000) as the instream flow compliance monitoring pointfor the Blewett Falls
Development.
The proposed reservoir fluctuation limits include an April 15 to May 15 period of lake level
stabilization to enhance spawning conditions for largemouth bass at both Tillery and Blewett Falls
developments (Table C-2). Progress Energy has had an informal voluntary agreement with the
NCWRC since the early 1980s to stabilize lake levels in Lake Tillery during this period to benefit
the largemouth bass population. As part of its proposed protection, mitigation, and enhancement
(PM&E) measures for the Project, Progress Energy would make this aformal license condition for
Lake Tillery, as well as for similar stabilization conditions for Blewett Falls Lake.
Future lake level fluctuations would not differ significantly from current conditions; however,
Progress Energy is proposing to reduce its currently allowable fluctuation from 22 ft at Tillery and
17 ft at Blewett Falls to the schedule of fluctuations shown in Table C-2.

3.2.2 Water Quality Enhancements
Water quality in the Yadkin-Pee Dee River was identified as an issue of concern through the RWG
consultation process (Water RWG Issue No. 7 -Lake Tillery and Blewett Falls Lakes Tailwaters
Water Quality; Water RWG Issue No. 8 -Water Quality, Blewett Falls Lake and Downstream).
Study plans were finalized in January 2004 and field work was performed in 2004 and 2005.
Progress Energy issued draft and final reports of the work completed prior to the Draft License
Application, which was issued in November 2005.
As a result of the studies performed, Progress Energy has subsequently developed a Dissolved
Oxygen (DO) Enhancement Program for coming into compliance with State of North Carolinawater
quality standards for DO. Compliance with DO water quality standards will be the basis for issuing
a 401 Water Quality Certification for the Project by the State of North Carolina.
The schedule for this program covers the period from 2006 through 2011. Progress Energy intends
to implement by December 2011 the most cost-effective technology at each development that
ensures compliance with North Carolina water quality DO standards. Progress Energy proposes to
complete field testing of options by December 2008 and to complete successful implementation at
both developments by December 2011. The sequence for implementing the DO enhancement
program is presented below (a detailed description ofthe program is discussed in Exhibit E3, Water
Use and Quality). This schedule assumes that the new operating license for the Project will be
issued by the FERC during the first six months of 2008.

3.2.3 Fish Passage/Protection
Diadromous fish passage was identified as Issue No. 4 (Support Development of Diadromous Fish
Restoration Plan) by the Water RWG. Progress Energy believed a necessary first step was
developing a set of agreed-upon study plans, including the development of a comprehensive
restoration plan forthe Yadkin-Pee Dee River Basin. The U.S. Fish and Wildlife Service (USFWS),
in coordination with the National Marine Fisheries Service (NMFS), North Carolina Wildlife
Resources Commission (NCWRC), and South Carolina Department of Natural Resources (SCDNR),
have recently completed a diadromous fish restoration plan for the Yadkin-Pee Dee River Basin
(LTSFW S et al. 2006). This plan identifies specific restoration goals and metrics for diadromous fish
populations in the river basin. The USFWS has issued a revised final version of this diadromous
fish restoration plan entitled "Restoration Plan for the Diadromous Fishes of the Yadkin-Pee Dee
River Basin, North Carolina and South Carolina, March 27, 2006" (i.e., Restoration Plan) which
outlines specific restoration goals and measures. This Restoration Plan was prepared by the
cooperating federal (USFWS, NMFS) and state (NCWRC, SCDNR) resource agencies to set a
framework for restoration of diadromous fish species to available and suitable portions of their
historical range in the Yadkin-Pee Dee River basin.
As stated in the Restoration Plan, "The goal ofthis plan is to restore the historical species diversity
where feasible and desirable, andto increase the sizes ofself-sustaining diadromous fish populations
in the Yadkin and Pee Dee Rivers." The restoration plan describes the benefits of restoration as,
"Successful restoration of diadromous fisheries in the basin is expected to have significant
ecological benefits as well as benefits to recreational and commercial fisheries." The plan also
acknowledges that while restoration to historic population levels may not be reasonable under
G7

Application for License Yadln~n-Pee Dee River Hydroelectric Project
existing conditions, the increase in numbers offish to the corresponding habitat carrying capacity is
asignificantrestorationgnal. Progress Energy supports arational,sequentially-phased approachto
restoration as outlined in the Restoration Plan.
As a result of the analysis performed by Progress Energy subsequent to consultation and the draft
and final fisheries restoration plans developed duringthe relicensing, Progress Energy has developed
a diadromous fish passage implementation plan whereby fish protection and passage at the Project
consists of an objectives-oriented, phased multi-year approach to fish passage to be implemented
during the term of the next license period. This implementation plan will consist of population
monitoring and evaluation offish passage designed to meet the goals and objectives ofthe Pee Dee
River Diadromous Fish Restoration Plan. The proposed schedule for implementing this plan is
presented below. Additional detail is provided in Section 4.6 of Exhibit E4.
^ 2008 Progress Energy license issued; begin annual population monitoring.
- Continue through license period (2058) or end of the program.

Falls Dam.
^ 2024 First adult shad return from trap and transport above Blewett Falls Dam.
^ 2025 Decision point: Evaluate fish passage program Continue trap and transport or adjust
upstream passage targets based on passage data results.
3.2.4 Recreation Enhancements
Recreation within the Project Boundary was identified as an issue needing study by Progress Energy
and the RWGs. The study plans were finalized in January 2004, and field efforts (including a
C-8

Application for License Yadln~n-Pee Dee River Hydroelectric Project
recreation survey) were performed in 2004 to 2005. Progress Energy has issued draft and final
reports of the efforts completed to date in the Draft License Application, which was issued in
November 2005.
After the completion of the stakeholder consultation and recreational studies, Progress Energy
analyzed the Project record and study findings to determine the need for recreational PM&E
measures aY the Project. Progress Energy proposes extensive recreational PM&E measures for the
Tillery and Blewett Falls developments.
The PM&E measures will provide the public with additional access and recreational opportunities at
the Project during the next license term. The issue of overcrowding at public access areas was not
generally perceived as an issue of concern by recreational users visiting facilities at either of the
Project lakes. Issues identified by recreational users were related more towards misuse of the
facilities and less towards boater use levels. Detailed site plans for recreational enhancements, the
proposed implementation dates, and the responsibilities of the involved parties will be filed with
FERC after issuance of the new license.
Tillery Development
Progress Energy proposes to make several improvements atfour public boating access areas located
on Lake Tillery: the Lilly's Bridge, Swift Island, Norwood, and Stony Mountain access areas.
Generally, improvements to these areas include the addition of public sanitary facilities, trash
receptacles, improved, structured parking areas, additional public information signage, and updating
the Project public information kiosks. Picnic shelter facilities are also being proposed for the Swift
Island and Norwood access areas.
At the Stony Mountain access area, Progress Energy proposes to construct afishing pier and access
trail. The facility will be located adjacentto the access area on Project lands. The fishing pier will
be handicapped accessible and meet requirements underthe Americans with Disabilities Act (ADA).
Progress Energy will donate $25,000 to the NCWRC for construction of the facility and will work
with the NCWRC in providing signage directing the public to the facility and public information
kiosk.
Progress Energy proposes to work with the NCWRC to co-fund with matching dollars the
construction of a boat house and access ramp for use by enforcement personnel on Lake Tillery.
This facility will permitthe NCWRC to respond more effectively to boating emergencies on the lake
and serve as a central point for safe boating enforcement activities on the lake. The proposed
location is on the main lake side of the Project lands on the peninsula located adjacentto and south
of the Stony Mountain boating access area.
Progress Energy will consult with the NCWRC on effective means to discourage public use of the
informal public access area at State Roads 1740 and 1745, locally known as the Steel Bridge Area.
The development of the proposed public fishing pier at the nearby Stony Mountain boating access
area will provide additional public fishing opportunities to more than offset opportunities that may
be lost with the closure of this informal access area.
Progress Energy proposes to relocate the existing informal public boating access area located in the
tailrace immediately below the Tillery Plant. Progress Energy, in consultation and partnership with
G9

Application for License Yadln~n-Pee Dee River Hydroelectric Project
the NCWRC, will develop and construct a new public boating access area located at the mouth of
Clarks Creek, approximately one-half mile below the power plant and one-quarter mile from the
current access area. Public access to the Clarks Creek boating access area will be from the power
plant access road (i.e., Tillery Dam Road) which is located off State Road 1103 and N.C. Highway
731. The boating access area will have aformal, structured gravel parking lot with designated ADA
parking places.
Blewett Falls Development
Progress Energy proposes to build anew public boating access area on the Richmond County side of
Blewett Falls Lake within five years of issuance of the new license. The new boating access area
will be located in the lower lake area on the opposite shore of the existing Pee Dee access area
located on the Anson County side ofthe lake. Progress Energy will workwith local county officials
and interested landowners to site the new public boating access area, and with NCWRC on design
and construction. Progress Energy will also work with the NCWRC to minimize shoreline
disturbance and impacts to the shoreline area during the construction of the facility.
Progress Energy proposes to include several improvements atthe two existing public boating access
areas located on Blewett Falls Lake. At the Pee Dee Access Area, Progress Energy will provide a
picnic shelterfacility, public sanitary facilities and trash receptacles; update the public information
signage including a new Project information kiosk; and improve parking facilities for vehicles and
boat trailers. At the Mountain Creek (Grassy Islands) Access Area, Progress Energy will provide
trash receptacles; update the public information signage including anew Project information kiosk;
and improve parking facilities for vehicles and boattrailers. Atboth sites, Progress Energy will also
work with the NCWRC to improve the boat ramps which permit effective boating accessibility
suitable to the range of lake levels proposed for the new license term.
Progress Energy proposes to upgrade the canoe portage facility located on the east shoreline of
Blewett Falls Lake at the dam to applicable state recreational standards. Progress Energy will
provide an electronic link on its external Company Internet web site that will allow the public to
access real-time Pee Dee River stream flow data at the USGS Rockingham gage station (USGS
Gage No. 02129000). This stream flow information can be used to plan boating recreational
activities for the Pee Dee River located below the Blewett Falls Hydroelectric Plant.
3.25 Other Enhancement Measures
Since the issuance of the ICD (February 2003) and Joint Public Meeting (March 2003), Progress
Energy has worked closely with the stakeholders to determine the potential PM&E measures to
implementforthe future operation ofthe Tillery and Blewett Falls developments. In addition to the
specific issues identified bythe RWGs for further study, several separate issues were identified for
the Project.
The following outlines Progress Energy's recommended schedule for implementing its other
proposed enhancement measures.
Subsequent to consultation performed during the relicensing process, Progress Energy agreed to
develop a Historic Properties Management Plan (HPMP). Progress Energy has developed an
archeological sensitivity model, completed an evaluation ofthe Projectfacilities' NRHP-eligibility
C-10

Application for License Yadln~n-Pee Dee River Hydroelectric Project
and will be continuing Section 106 consultation with the North Carolina SHPO, the Catawba Indian
Nation, and the Eastern Band of the Cherokee Indians on the integration of the archeological
sensitivity model results into the Tillery Shoreline Management Plan (SMP) and Blewett Falls
Shoreline Management Policy. The details about additional protection, mitigation and enhancement
(PM&E) measures for historic properties will be incorporated into the HPMP approved by FERC as
appropriate.
Lake Tillery
Progress Energy submitted a SMP for Lake Tillery to FERC on December 28, 2001. The SMP was
approved by FERC, with modifications, on November 24, 2004. Progress Energy has implemented
the Tillery SMP over the term of the neat license.
As a result of the analysis completed by Progress Energy after the consultation efforts performed
during the relicensing process, Progress Energy will coordinate with the USFW S' Pee Dee River
National Wildlife Refuge for purposes of providing flows when filling of refuge migratory
waterfowl ponds. Progress Energy will initiate coordination following issuance ofthe new license.
Blewett Falls Lake
Progress Energy is proposing to adopt a protective shoreline management policy for Blewett Falls
Lake that will preserve the natural resource values of the lake. This shoreline policy will prohibit
private access to the lake across Project lands except atthe designated public access areas. The plan
will focus on resource protection. This managementpolicywill beformally adopted after FERC has
issued the new license for the Project.
Sediment transport and gravel recruitment at Blewett Falls Lake were identified as issues by the
Water RWG. As a result of the field studies and analyses completed by Progress Energy as part of
the relicensing process, there was no evidence found in either study of any significant Project
effects. Progress Energy will conduct a similar lake sediment survey in Blewett Falls Lake and an
additional gravel recruitment survey in the Pee Dee River downstream of the Blewett Falls Dam
within five years of issuance of the new license. If results continue to indicate that no significant
problem exists, Progress Energy will conduct one additional study after 10 additional years.

2.0 Estimated Cost of Takeover Pursuant to Section 14 of the Federal Power
Act
In the event the Project should be subject to a federal takeover, the estimated current gross plant
investment as of December 31, 2005 is $30,445,596. To establish potential severance damages, a
determination would have to be made of the potential benefits of the Project operations that would
have to be replaced over the term of a 50-year license. This figure would be based on the revenues
generated by the Project for this term. The estimate of the severance damages would be based
primarily on the net present value of the net annual benefits for the full term of a new license. These
values would need to be calculated for the prevailing market conditions at the time it is determined
severance damages are applicable.

3.0 Existing and Future Cost of Project Power
3.1 Land and Water Rights
There is no proposal by Progress Energy to expand land or water rights as part of this license
application.
3.2 Cost of New Facilities
Progress Energy is proposing certain modifications to the existing project works. Incorporated into
the Preferred Plan presented as part ofthe license application, Progress Energy has proposed several
significant resource enhancements. The costs for these enhancements are shown in Table D-1.
Table D-1 Estimated cost and schedule for Project enhancements.
Estimated Cost
Proposed Enhancement iotttt~ n ~~ ~ Implementation Year
DO Enhancements $2,000,000 2011
Upstream Fish Passage $4,000,000 2018
Recreation $600,000 2010
These costs are very preliminary. There is not yet an agreement on the final design and
configuration offish passage facilities; nor has sufficient detailedfield testing been accomplished to
determine the most cost-effective dissolve oxygen enhancementtechnology for either development.
The current annual operations and maintenance (O&M) costs associated with the Project are as
follows:
^ O&M and Administration .................................................................................... $3,132,4761
^ Property Taxes ......................................................................................................... $133,679
Total ..................................................................................................................... $3,266,155
Based on the costs outlined above and the average power generated in a year, the average annual
cost of power can be calculated as follows:
Cost of Power ($/MWh) _ $3,266,155 / 326,000 MWh
_ $10.01 /MWh
Projected Future Cost of Project Power
The future annual cost ofthe Yadkin-Pee Dee River Project generation will include annual operating
costs, plus the cost of capital, plus the costs of new resource enhancement measures. Assuming a
two percent increase in operating expenses per year, the estimated average cost of the total project
will be approximately $4,600,000 per year, based on a 15-year period of analysis.
The PM&E measures proposed for the operation of the Yadkin-Pee Dee River Project have been
estimated to reduce the capacity of the Project by approximately five percent. Progress Energy

predicts that future average annual generation will be approximately 309,000 MWh. Based upon
these assumptions, the cost of future power will be as follows:
Cost of Power ($/MWh) _ $4,600,000/309,000 MWh
_ $14.88 /MWh

2.0 Project Maps
Progress Energy has included general maps depicting the Project Boundary forthe Yadkin-Pee Dee
River Project to this License Application. These maps are listed in Table G-1. These drawings are
organized by Project development and are based on the maps provided in the Initial Consultation
Document (Progress Energy 2003).
Table G-1 presents alistofthe maps included inthe Non-Internet Public Volume ofthis application.
Progress Energy is currently in the process ofupdatingthe Exhibit G Projectmaps to conform to the
requirements of 18 CFR § 4.41(h).
Table G-1 Project maps for Progress Enemy's Yadkin-Pee Dee River Project
Tillery Development Project Area -Sheets 22 through 55 of 55
Blewett Dwelopment
21 of 55
Progress Energy performed a comprehensive evaluation of the existing FERC Project Boundary
during the relicensing to determine whether the existing Project Boundary satisfied FERC
regulations. The evaluation of the current boundary revealed only one location where Progress
Energy believes there are lands that can be excluded from within the existing boundary due to the
fact that the lands do not serve Project purposes. The change in the Project Boundary is identified
on Exhibit G Sheet 12A.
The new Project Boundary is proposed in a location that provides a 100-foot buffer to the existing
normal maximum head pond elevation shoreline of Blewett Falls Lake. The configuration of the
proposed Project Boundary is consistent with FERC's regulations at 18 CFR § 4.41(h)(2)(i), which
requires that the boundary of an impoundment must be no more than 200 feet from the exterior
margin of the reservoir when it is at its normal maximum surface elevation.
Consistent with FERC regulations and guidance on handling of Exhibit G maps, these maps are
designated and are being filed as "Non-Internet Public".

2.0 Information to be Provided by All Applicants
This section addresses alternative power generation sources, the Project's effects on customers and
communities served, conformance with comprehensive plans, and Progress Energy's financial
resources.
2.1 Plans and Abilities to Operate and Maintain the Project and Provide Efficient
and Reliable Electric Service
Progress Energy has aproven trackrecord of over 75 years of performance in managing, operating,
maintaining, and improving the Yadkin-Pee Dee River Project in a manner that delivers efficient,
reliable electricity at low cost. At the same time, Progress Energy has served as a diligent and
responsible manager ofthe natural and recreation resources under its stewardship. For example, the
existing license allows drawdowns at Lake Tillery of up to 22 ft below full pond. Over the past
several years, Progress Energy has voluntarily made its best efforts to operate Lake Tillery within a
4-ft range under normal conditions, and for much of the prime recreation season keeps the lake
within a 1- to 2-ft range.
The Yadkin-Pee Dee River basin reached "exceptional drought" classification, the most serious
category, in the summer of 2002. To respond to the public health and safety concerns that arose as a
result of the drought, Progress Energy worked proactively with water resource authorities from both
states, as well as Alcoa Power Generating, Ina (APGI) to collaboratively develop a new water
release protocol for the coordinated operation of both Progress Energy's and APGI's hydroelectric
projects to manage the river during the drought period.
The Yadkin-Pee Dee River Project (Project) provides an annual average energy supply of
335,000 MWh of clean, renewable hydroelectric energy. Compared with fossil-fuel produced
energy, this represents a annual displacement of approximately 580,000 barrels of distillate oil,
143,100 tons of coal, or 3,300 million cubic feet of natural gas, thereby conserving fossil fuels and
avoiding greenhouse gas emissions.l
2.1.1 Plans for Increased Capacity or Generation
The Tillery and BlewettEalls developments fill an importantrole in Progress Energy's control area
management. This is especially true of the Tillery plant which is a critical component of Progress
Energy's resource mix. The Tillery plant frequently is relied upon by energy and transmission
system managers for load-following purposes. The Tillery plan is Progress Energy's only hydro
project of sufficient size and operational capability to operate in an Automatic General Control
(AGC) mode. This constitutes aunique role forthe Tillery plant as it is often called upon to operate
at the peak of demand, control frequency and voltage, and assist with load transfers across control
areas.
While Progress Energy does not currently have any plans to increase capacity or generation at the
Proj ect, with the Preferred Plan proposed, Tillery and Blewett Falls will be able to continue to play a
key role in Progress Energy's resource mix.

2.1.2 Project Coordination with Upstream and Downstream Projects
The Project is operatedto provide peaking, load-following, and system control services; however, its
operations are significantly affected by the operation and management of the upstream Yadkin
Project. APGI's Yadkin Project consists of four developments: High Rock, Tuckertown, Narrows,
and Falls. In general, High Rock Lake and Narrows are operated in astore-and-release mode, and
Tuckertown and Falls are operated primarily as rnn-of--river developments.
In accordance with Article 29 of the Yadkin Project's FERC license, the upstream Yadkin Project
mustbe operated in amannerthat allows Progress Energyto meet its continuous flow requirements.
Yadkin's seasonal operations are in accordance with arnle curve developed to manage lake levels at
High Rock Lake. Under normal and dry conditions, this rule curve governs the general level of
inflows into Narrows Reservoir and subsequently into Lake Tillery. A FERC Order Amending
License issued in March 1968 (39 FPC 397) also requires Yadkin to maintain arecreational pool for
High Rock Lake. Outflows from APGI's Yadkin Project flow directly into Lake Tillery.
On January 24, 1968, APGI filed with FERC a letter agreement (dated January 15, 1968) between
itself and Carolina Power & Light (CP&L) (now Progress Energy) related to the settlement of
headwater benefits in the Yadkin-Pee Dee River basin. This agreement modified an agreement of
February 19, 1926. The 1968 agreement includes the following relevant provisions for operation of
High Rock Reservoir:
^ During the 10-week period preceding the recreation period (May 15 through September 15),
regulated weekly average streamflow from High Rock would be reduced to aflow of not less
than 1,500 cfs so as to permit High Rock reservoir to refill by May 15.
^ During the period May 15 through July 1, the regulated average weekly streamflow would be
reduced to a flow of not less than 1,610 cfs.
^ During the period July 2 through September 15, the regulated average weekly streamflow
would be reduced to a flow of not less than 1,400 cfs.
FERC found that the agreement dated January 15, 1968 constituted an effective and reasonable
method of compensation for headwater benefits received by Progress Energy at Project No. 2206
from APGI's Project No. 2197 in accordance with Section 13.1 of FERC's Regulations under the
Federal Power Act.
In practice, operations personnel at APGI's Yadkin Project provide a weekly release schedule to
Progress Energy operators the preceeding Friday. Tillery plant operations are then planned for the
week on the basis of the flow information provided by APGL Tillery operations, likewise, set the
stage for the operation of Blewett Falls. In the past, APGI operations have not always followed the
release schedule providedto Progress Energy, and this has resulted in disruptions to Progress Energy
operations. At the same time, APGI operations have very consistently met the terms of the
Headwater Benefits agreement.
Outflows from Tillery flow directly downstream to the Blewett Falls Development. Under normal
conditions, it takes the water approximately 8 hours to arrive at Blewett Falls from Tillery.
Generally, Blewett Falls is block-loaded during peak demand periods.
H-7

Application for License Yadln~n-Pee Dee River Hydroelectric Project
Operations at Blewett Falls are primarily dependent on the outflows from Tillery. Typically all six
(6) generating units at Blewett Falls are operated at economy load as soon as the Tillery hydro
station begins to generate. With the water travel time delay, Blewett Falls generates duringthe day
and draws down its reservoir approximately 2 to 4 ft. Subsequently generation usually ends well
before midnight. Generating in this manner at Blewett Falls provides power when needed most, and
allows the reservoir to refill overnight.
There are no other projects located downstream of the Blewett Falls Development.
2.1.3 Coordination of Project Operation with other Electrical Systems to Minimize the Costs of
Production
Progress Energy has direct interconnections with American Electric Power, Duke Power Company,
South Carolina Electric & Gas Company, South Carolina Public Service Authority, Tennessee
Valley Authority, Yadkin, Inc., and Dominion Virginia Power. Progress Energy has coordinated its
transmission planning and operations to assure the continued safety, reliability, and economy of its
power system. Progress Energy actively participates in inter- and intra-regional studies. Detailed
near-term operating studies and longer-range planning studies are made on aregular basis to ensure
that transmissioneapacity will continue to be adequate. These studies involve representatives from
the Virginia-Carolinas Subregion (VACAR) and adjacent subregions to provide interregional
coordination. Progress Energy actively participated onthe VACAR-Southern-TVA-Entergy (VST),
the VACAR-AEP-Southern-TVA-Entergy (VAST), the VACAR-ECAR-MAAC (VEM), and the
VACAR inter-regional reliability committees and participated in the following studies during the
2004-2005 time frame: 2004 VAST Summer Reliability Study, 2004/05 VACAR Winter Stability
Study, 2004/05 VAST Winter Reliability Study, 2004 VEM Summer Reliability Study, 2011 VST
Summer Study, 2004/05 VEM Winter Reliability Study, and 2005 VACAR Summer Reliability
Study. These studies are required to comply with contractual obligations associated with the
VACAR, VEM, and VST agreements. Copies of these study reports are available from the SERC
Administrative Office. SERC is Progress Energy's region of NERC. Results of these studies
indicate that existing facilities, along with those planned to meet the future reliability needs, will
provide limited economy and emergency transfer capability between the subregions and regions.
Blewett and Tillery hydro generation is represented in these studies.
2.2 License's Need for Project Electricity over Short and Long Term
The peaking and load-following power provided by Progress Energy's Project are important
resources needed to meet customer and system needs. Based on the Progress Energy Carolina's
Resource Plan, September 2004 (Resource Plan), Progress Energy's integrated planning process
combines existing and new generation resources, demand-side management programs, and
purchased power contracts in a portfolio that will provide reliable electric service at a reasonable
cost.
The short-term need for Project power is vital because it is areadily available power source that can
provide peaking power at a reasonable cost to its customers and is one of the few load-following
resources in Progress Energy's control. Progress Energy has several power sales agreements with its
customers and the term of electricity commitments will vary during the license period. The
Resource Plan identifies 10 existingwholesale power sales commitments within the states of North
Carolina and South Carolina
H-8

Application for License Yadln~n-Pee Dee River Hydroelectric Project
In order to provide reliable service and meet power sales commitments, a margin of generating
capacity reserve is required. Even though the amount of reserve required is a function of several
factors that make up a unique utility system, the Project is a significant resource for meeting reserve
capacity requirements.
Progress Energy anticipates adding more than 2,000 MW of capacity over the nextten years, which
is an indication of the long-term need for project power. A breakdown of the installed generation,
demands, reserves and anticipated additions from 2005 through 2014 is provided in Appendix H-1 of
this Exhibit.
2.2.1 Load Growth
Progress Energy's forecasting processes have used econometric and statistical methods since the
mid-70s. Significant improvements to these methods have been made during this time frame with
the advent of the computer age and associated software developments. The current load forecast
method combines the System Peak Load Forecast and the System Energy Forecast, assuring
consistency of assumptions and data.
Progress Energy has forecasted load growth in several categories forthe summer and winter seasons
during the years from 2005 through 2014. Based on the Resource Plan, the total summer load,
which includes peak load, firm sales, and curtailment is forecasted to grow by 15 percent during this
10-year period. Likewise, the total winter load during this time period is also forecasted to grow by
15 percent.
While it is anticipated that the future growth rate of personal income and Gross Domestic Product
per capitawill decrease relative to the historic growth rate, the continued operation of the Project is
an important contribution to meet the forecasted load growth in the region.
2.2.2 Costs and Availability of Alternative Power Sources
If Progress Energy were not to receive a license for the Project, the capacity would have to be
replaced through power purchases (often during high market price periods) and/or installation of
new generating facilities, such as combustion turbines. Either of these resource options would be
significantly more expensive than continuing to operate the Project, increasing the cost to Progress
Energy's customers.
Progress Energy has several purchase agreements existing with other companies, so that would be
the logical alternative power source for the short-term need. While power purchase agreements of
this capacity may be readily available, power purchases to offset the Project capacity may entail
expensive transmission upgrades, due to the heavy subscription of transmission capacity.
The long-term alternative power source would likely include installation of a combustion turbine
generator (CTG). The Resource Plan provides an economic comparison indicating that CTGs are
the most economical generation alternative for peaking duty cycles, which is consistent with
findings by the Energy Information Administration (EIA). However, the replacement of Project
generation by a CTG would: (1) require a great deal of additional capital investment (example is a
H-9

Application for License Yadln~n-Pee Dee River Hydroelectric Project
106 MW CTG [84 MW and 22 MW capacity for Tillery and Blewett, respectively] which cost
approximately $44,000,000); and (2) result in increased variable costs for energy generated.
Amore detailed discussion of all alternative power sources considered is provided in Section 2.3.
2.2.3 Effects of Alternative Power Sources
Alternatives for replacement power would undoubtedly have identifiable impacts on customers and
communities served by the Project. The most predictable impact would be the higher cost ofpower
and less flexibility for these customers, as well as greater potential vulnerability to future regional,
power-supply fluctuations. The most likely scenario for ashort-term plan of alternative power
would be a purchase agreement from one of Progress Energy's existing power providers. The
dependence on these purchase agreements compromises Progress Energy's ability to provide
customers with the lowest cost of reliable electricity.
2.2.3.1 Effects on the Customers of Progress Energy
In accordance with its Residential Service Schedule for single-phase service, Progress Energy
charges $6.75 per month plus $7.657 cents/kW during billing months of November through June
(Progress Energy 2005). This rate is amongthe lowest as currently charged by nearby utilities. Any
alternative source of power will increase power costs, increase volatility and risk, and reduce long-
term certainty. The adverse impacts of any cost increases would be significantfor the customers in
the immediate vicinity.
2.2.3.2 Effects on Operaring and Load Characterisrics
The loss of Proj ect power would have direct effects on its operating and load profile. Hydropower is
extremely flexible, and especially well suited to meetingthe last increment of load on a system. The
Tillery Development is designed to be operated to meet peaking, load-following, and system support
needs. Blewett Falls Development operates as apeakingfacility with "block loading." The peaking
operation at Tillery allows Progress Energy to provide electricity at periods ofpeak demand when its
ratepayers need itmost. Because of its critical load-following ability, Tillery is accustomedto adjust
to rapid changes in system needs and local transfers ofpower between control areas. Blewett Falls
is operated as a "block loaded" facility because the units are either operating at best efficiency or are
off.
Undoubtedly, every alternative source of power would have an immediate effect on river
coordination relative to a loss of Project power. Additionally, it is highly unlikely that Progress
Energy can purchase power or generate power from an alternative source and provide power during
peak demand with the same amount flexibility and reliability that it has demonstrated through
existing Project operations. The inherent uncertainty of a reliable alternative source equivalent to
that of the Project may have an adverse effect on the existing electrical system.
2.2.3.3 Effects on Communiries Served
The greatest impact of either the loss of Project power, or of a substantial increase in the cost of
power, would be to the rural communities. The 34,000-square-mile service area includes several
regions with extremely slow economic growth. Anson, Montgomery, Richmond, and Stanly
H-10

Application for License Yadln~n-Pee Dee River Hydroelectric Project
Counties are rural communities within the service area and have lagged in population growth,
income growth, and wealth. Manufacturing, which represents the highest percentage sector of
employment in these counties, depends on low-cost reliable power.
If low-cost Projectpowertyere not available, there would be a significant adverse economic impact
to low-income families, the manufacturing industries, and other customer bases located in many of
the rural communities served by Progress Energy.
2.3 Need, Cost, and Availability of Alternative Sources of Power
Progress Energy has conducted an assessment of various alternative generating technologies to
ensure thatprojectionsfnr new resource additions consider emergingtechnologies. The assessment
includes ascreening of generation alternatives, associated costs and performance. The first criterion
of the assessment is to determine the commercial availability of each technology for use in utility-
scale applications. Ifthe first criterion is metthen Progress Energy considers the applicability ofthe
alternative source within the region and ability to match the technology to the service it would be
required to perform. In essence, the technology must be able to be operated on a commercial scale
in continuous service by or for an electric utility, meet Progress Energy's particular generation
requirements, and be economically viable.
The alternative conventional technologies, which are commercially available and have a history of
acceptance and operating experience, include combined cycle combustion turbines fired by natural
gas, fuel oil, or pulverized coal. While these non-renewable technology sources are widely
accepted, fuel price has a direct impact to the generation cost. Consequently, fuel price is one ofthe
most significant factors that drive the market demand for a specific power generation source. Coal-
fired generation facilities in particular require a substantial amount of capital to operate given the
nature of the fuel and associated storage and handling equipment required.
Demonstrated and emergingtechnologies may be commercially available but notfully developed or
demonstrated on the utility scale. These technologies include wind power and wood waste burning,
which are demonstrated and proven technologies for the utility sector. Fuel cell and solar
photovoltaics (PV) are considered to be emerging technologies.
As of 2000, wind power has not accounted for any renewable power generation in either North
Carolina or South Carolina (EIA 2005a). In general, wind power does not have the reliability or
flexibility of hydro. In fact, using wind as a source of power presents a substantial amount of risk
for a utility because it is intermittent and it does not always blow when electricity is needed. Wind
energy cannot be stored (for large scale applications batteries render it costprohibitive), and wind
can not provide any degree of load following. Because wind is an intermittent electricity generator
and does not provide power on an "as needed" basis, it does not compare favorably with the costs
associated with operating a hydropower generation facility.
Other demonstrated technologies including Wood, Municipal Solid Waste, and Tire Burning
generation have high "levelized" costs and are subject to considerable environmental emission
challenges.
Fuel Cells appear to be competitive from a cost standpoint, but they are currently still in the
demonstration stage. Even though they can be assembled in a "building block" design, a sufficient
H-11

Application for License Yadln~n-Pee Dee River Hydroelectric Project
number offuel cells cannot be practically assembled to create source of generation for autility-type
of project.
Solar Power or solar PVs in the southeast is constrained from achieving a high capacity factor.
Assuming a capacity factor of ~20 percent, they are unsuitable for intermediate or baseload duty
cycles. Additionally, they are not currently economically competitive generation technologies. As
of 2000, solar power has not accounted for any renewable power generation in the Carolinas.
2.3.1 Basis for Determining Cost of Project Power
The annual operating cost of power from the Project is as follows:
^ Operation and Maintenance ................................................................................. $3,132,4762
^ Property Taxes .................................................................................................... $133,678.75
^ Total ..................................................................................................................... $3,226,155
2.3.2 Average Annual Cost of Power Generated
Based on the costs outlined above and the average power generated in a year, the average annual
cost of power can be calculated as follows:
Cost of Power ($/MWh) _ $3,226,155 / 326,000 average annual generation (MWh)
_ $10.01 /MWh
2.3.3 Average Annual Cost of Power from Alternative Sources
The Renewable Fuels Module (RFM) ofthe National Energy Modeling System provides information
for forecasts of new generating capacity using renewable energy sources (EIA 2005b). Table H-1
below provides estimated costs based on the RFM for some of the alternative energy sources that
Progress Energy has considered in their Resource Plan.

of the example technologies in the RFM are based on a capacity which varies significantly from the Project capacity,
which may affect the projected capital cost to replace Project power.
z Estimated for 2006.
H-12

Application for License Yadln~n-Pee Dee River Hydroelectric Project
If Progress Energy had to replace the Project power, the least expensive alternative would be to
install a CTG. Based on the Progress Energy Resource Plan, assuming the same Project capacity
factor of 35 percent, the annual levelized cost would be $190/kW-yr, which is lower than the EIA
estimated cost provided in Table H-1 above. However, removal of the Project would increase the
burden on other market resources in the area, or would increase the amount of energy imported. The
most important consequence may be that acost-effective, pollution-free, renewable source of energy
would be lost.
2.3.4 Relative Merits of Alternative Sources of Power
Whether, the Proj ect power is replaced by installing a CTG or by purchasing power, it is difficult to
accurately predict the cost of power for the long-term. Project power provides Progress Energy's
customers reasonable assurance ofthe long-term availability of a dependable, low riskpower supply
forthe entire new license term. However, this is notthe case for any alternative source ofpower. If
Progress Energy were to rely on purchased power, there would be no way to ensure that affordable
power would be available through this same period. The alternative of entering into along-term
purchase contract diffuses the risk in the power marketplace, but denies Progress Energy of the
security, operational, and reliability benefits that are currently realized by owning and controlling its
own resource.
Relying on a CTG satisfies the long-term power dilemma, albeit with a resource with a typical
average life of 25 to 30 years. Combustion turbines as a replacement source would provide Progress
Energy with adequate base load energy to meet current reliability and system operating
characteristics. However, combustion turbines do not have the economic ability to compete with a
more flexible hydroelectric resource that can adjustto loads, meet instantaneous demand, and satisfy
emergency shortages efficiently. Another drawback is the susceptibility to longterm natural gas
prices (or the cost of hedging this volatility) and availability.
Other thermal plants that use coal or biomass for fuel could provide the power required to replace
the current Project capacity. However, the use of these facilities for this purpose, as opposed to
operation at a designed constant output, will have numerous negative consequences including:
^ a much slower electrical output response;
^ the use of more fuel with greater uncertainty of its long-term availability;
^ output of more pollutant and greenhouse gas emissions, and
^ increased maintenance costs due to thermal cycling.
While other renewable energy sources, like wind, fuel cell and solar are thought to be more
environmentally friendly, they lack capacity in this region and cannot compete economically.

2.6 Impact on Planning and Operation of Transmission System if Progress Energy
Does Not Receive the New License
The Progress Energy transmission system consists of approximately 6,000 miles of transmission
lines and just over 100 transmission-class switching stations in the Carolinas service area The
primary purpose of the transmission system is to provide the electrical path necessary to
accommodate the transfer ofbulkpower as required to ensure safe, reliable, and economic service to
control area customers.
From a planning perspective, Progress Energy's transmission system relies on the operation of
Blewett and Tillery generation to support load and voltage during peak load periods. Progress
Energy's transmission planning criteria includes assessments of single line outages in combination
with the outage of any unit such as those at Blewett and Tillery. Blewett has six hydro units and
Tillery has four hydro units. Power flow and dynamic reactive power from these facilities is
therefore integrated into Progress Energy's transmission planning. From an operations perspective,
operation typically results in Blewett and Tillery generation being utilized at system peaks and are
good for regulation and load following.
Progress Energy's transmission planning studies are based on the Company's long-range system
peak load forecast, which includes territorial load and contractual obligations, and the Company's
Resource Plan. The transmission planning process andthe generation resource planning process are
interrelated. Progress Energy recognizes that generation additions have significant impacts on the
adequacy of the transmission system. The continued flow of Project-generated power will not
adversely impact Progress Energy's transmission system. However, in the event that Progress
Energy does not receive the new license, generation of power over the existing transmission grid
would continue.
Progress Energy's transmission system relies on the operation of Blewett and Tillery generation to
support load and voltage during peak load periods. Progress Energy's transmission planning criteria
includes assessments of single line outages in combination with the outage of any unit such as those
at Blewett and Tillery. Progress Energy currently has a transmission project to relieve loading on
the Rockingham-Blewett Plant-Tillery 115 kV corridor under contingency outage of other facilities.
The scope of the solution for this problem includes the construction of 14 miles of new a 230 kV
transmission at an estimated cost of $9 million. The loading condition would worsen, and the
needed solution would be much more costly in the absence ofthe hydro generation of Blewett and/or
Tillery plants.
Progress Energy's transmission in the area of Blewett and Tillery plants is designed around the
presence of the plants. Without this generation, loadings on transmission lines serving this area
would experience increased flows and require additional dynamic reactive power. Generation plants
inherently provide dynamic reactive power supportto the local area. Replacing the reactive power
support provided by the Blewett and Tillery units would likely be from static capacitors added to the
local area since reactive power (MVARs) do nottravel farfromits source. Dynamic reactive power
is superior to static reactive power due to its ability to quickly respond to disturbances on the
transmission system.

2.7 Need for Planned Modifications of Project Facilities
Initial evaluations were made regarding the possibility of rehabilitating the Blewett Falls
powerhouse and modernizingthe existing equipment atthe Tillery Development. As aresult ofthe
analysis completed by Progress Energy after the consultation efforts and studies performed for the
relicensing, Progress Energy does not propose any Project-related improvements.
Progress Energy has developed a Dissolved Oxygen Concentration Enhancementprogram to address
meeting quality water standards at Tillery and Blewett Falls developments as required by Section
401 of the Clean Water Act. These standards are to be met within three years of issuance ofthe new
FERC license. Progress Energy proposes to complete fieldtesting options by December 2008 andto
complete successful implementation by December 201 L If this on-going effort results in any
substantial modifications to the existing developments, Progress Energy will submit revised
Exhibit F drawings to FERC for review and approval.
Progress Energy, in consultation with resource agencies, has proposed afish protection and passage
plan that will consist of a phased approach based on a multi-year program during the term of the
neat license period in orderto meet the goals and objectives ofthe Pee Dee River Diadromous Fish
Restoration Plan. Implementation of this plan will result in changes to project facilities (e.g.,
construction of upstream fish passage facilities) and operations (e.g., diverting flow through
fishways).
Progress Energy will also complete improvements at selected recreation facilities as a result of the
analysis completed by Progress Energy after the consultation efforts and studies performed for the
relicensing.
2.8 Comprehensive Plans
Under Section 10(x)(2) of the Federal Power Act, federal and state agencies filed with FERC (as of
March 200 a total of 39 comprehensive plans that address various resources in North and South
Carolina. In addition, a number of federal agencies have filed interstate plans, some of which are
relevant to North and South Carolina. Of these, we identified the plans which are relevant to the
Yadkin-Pee Dee relicensing (Table H-2). Throughoutthe relicensing process, Progress Energy has
engaged with federal and state resource agencies, through negotiations and settlement discussions,
with the intent of addressing agency concerns regarding project operation under the terms of a new
license. As a result of this intensive consultation with the resource agencies, Progress Energy has
proposed operating conditions and enhancement measures to address agency concerns, and
anticipates that the proposed project operation, developed in close consultation with resource
agencies, will be consistent with the management objectives represented by these comprehensive
plans.

South Carolina Coastal Zone Management Act (Title 48, Chapter 39, June 2002) as well as the
"Policies and Procedures of the South Carolina Coastal Management Program" (State of South
Carolina, July 1995) to determine whether the Yadkin-Pee Dee Project is located within the South
Carolina designated Coastal Zone. Progress Energy's review confirms that the Yadkin-Pee Dee
Project is not located in astate-designated coastal zone and does not affect coastal zone waters and
lands. Consequently, the proposed project is not subject to a determination of consistency with
South Carolina coastal zone policies.
2.9 Applicant's Financial and Personnel Resources
2.9.1 Financial Resources

2.11 Electricity Consumption Efficiency Improvement Program
Progress Energy has a number of conservation and energy efficiency, load management,
cogeneration, and renewable energy programs in effect. There are numerous programs that intend to
assist residential customers. Other programs strive towards the use of renewable sources. The list
below summarizes some of the energy efficiency programs for Progress Energy's customers
(Progress Energy 2005c):
^ Education and Awareness -For both retrofit and new home markets, Progress Energy
proactively educates the end-use customers, assists them with questions and provides
additional information, as needed, concerning energy efficiency.
^ Home Energy Check-This energy analysis tool (audit), which includes an on-line version
and amail-inversion, was first implemented in 2001 to assist residential consumers to better
understand their energy usage and make personalized recommendations for energy
improvements.
^ Energy Efficient Home -This program provides residential customers with a 5 percent
discount of the energy and demand portions of their electricity bills when their homes met
certain thermal efficiency standards that were significantly above the existing building codes
and standards.
^ Energy Star -Energy Star is the national symbol for energy efficiency. It is a partnership
between the DOE, the U.S. Environmental Protection Agency (USEPA), local utilities,
product manufacturers, and retailers. Homes built with this label are at least 30 percent more
efficient than the national Model Energy Code, have greater value, lower operating costs,
increased durability, comfort, and safety. Homes that pass an Energy Star test receive a
certificate as well as a 5 percent discount on energy and demand portions oftheir electric bills.
Builders receive training in building energy efficient homes, and a means of differentiating
their product on the market place.
^ Energy Efficiency Financing Program -Progress Energy sponsors this program, which
offers low-interest loans so that customers can purchase heating and cooling systems, storm
windows and doors, insulation and other cost-effective home improvements.
^ Large Load Curtailment -Using tariffs, industrial and commercial customers receive
discounts for Progress Energy's ability to curtail system load during times of high energy
costs and/or capacity constrained periods.
^ Voltage Control -This procedure involves reducing distribution voltage by up to 5 percent
during periods of capacity constraints.
^ Renewables-Progress Energy Carolinas is involved in several renewable energy activities.
Two of these include North Carolina GreenPower and Biodiesel.
^ North Carolina GreenPower is a statewide North Carolina effort to improve the environment
by using "green power" electricity generated from renewable resources such as solar, wind,
H-18

Application for License Yadln~n-Pee Dee River Hydroelectric Project
biomass and water. North Carolina GreenPower was launched in October 2003 following
months of development by a large number of stakeholders including Progress Energy.
^ Biodiesel, produced from organic feed stocks, is a renewable fuel that can be used in any
diesel vehicle with no modifications. Progress Energy supports the North Carolina Triangle J
Council of Governments biodiesel initiative by fueling some of Progress Energy's trucks at
two biodiesel fueling stations in Wake County, North Carolina.
^ Cogeneration -Progress Energy purchases electricity from 30 cogenerators or small power
producers, 23 of which utilize renewable resources to produce all or a part of the energy sold
to Progress Energy.
Progress Energy's energy conservation programs comply with all conservation program
requirements.

31 Measures Taken or Planned to Ensure Safe Management, Operation and
Maintenance of the Project
Progress Energy maintains state-of--the-art dam and plant safety, employee-safety, and public-safety
programs. These programs, based both on industry risk management and FERC standards, are
designed to minimize risks to the community, public, operating personnel, environment, and
physical plant.
The Emergency Action Plan (EAP) developed forthe Project specifies the procedures to ensure safe
management, operation and maintenance of the Project under emergency conditions (Progress
Energy 2004b and 2004c). The EAP addresses:
^ General provisions for surveillance;
^ Surveillance at remotely controlled or unattended areas;
^ Response during periods of darkness or adverse weather;
^ Availability and use of alternative systems of communications;
^ Emergency supplies and resources;
^ Access to Site;
^ Posting of the EAP;
^ Training, Testing and Annual Review; and
^ Site specific concerns.
3.1.1 Existing and Planned Project Operation during Flooding Conditions
Inflow to the Blewett Falls reservoir is monitored by both the Tillery Development control room and
the Blewett Falls control room and the outflow is monitored by the Blewett Falls Development
Control Room. In the event of a controlled discharge at the Tillery Development within the capacity
ofthe turbines and spillway at the Blewett Falls Development, the water surface elevation of Blewett
Falls Reservoir can be managed through coordination between the two operators. The reservoir
water surface elevation at the Project can be adjusted through operation of turbines. The Tillery
Project spillway gates which can be operated from its local push-button station or remotelyfromthe
control room, in addition to manual operation under extreme conditions.
3.1.2 Public Safety Measures, Including Warning Devices to Ensure Downstream Public Safety
Progress Energy maintains a comprehensive public-safety program to ensure the structural adequacy
of the developments and the safety of the public within the Project area. Both Tillery and Blewett
Falls developments are inspected annually by Progress Energy staff and representatives of the
FERC. Independent dam safety inspection consultants thoroughly examine the spillway and water-
retaining structures once every five years and publish acomprehensive Safety Inspection Report for
each development. The latest Part 12 Dam Safety and Inspection Report (Part 12 Report) for the
Project was prepared in 2004 by ARCADIS G&M, Ina (ARCADIS 2004a and 2004b).
Progress Energy maintains a current EAP for the Project in the extremely remote possibility that a
structural emergency would arise atthe Project. This plan is designed to minimize dangerto people
and property downstream ofthe Blewett Falls Development. The EAP provides concise guidelines
H-20

Application for License Yadln~n-Pee Dee River Hydroelectric Project
for notification and early warning of local, state and federal agencies, emergency services staff, and
the public in the event of an actual failure, potentially hazardous situation is developing, or
unusually large spillway releases. Developed in accordance with FERC guidelines, this plan is
tested and updated annually.
There are numerous conditions that could cause such an emergency, and the severity ofthe potential
hazard will dictate the remedial measure taken at each development. On-site personnel understand
that it is with utmost importance and urgency that downstream dams and communities be notified as
quickly as possible in orderto take whatever measures are necessaryto preserve the integrity of their
installations, civil structures and population base and minimize damage and destruction.
Safety barriers have been installed atthe upstream approaches at both Tillery Dam and Blewett Falls
Dam due to safety hazards caused by high winds, high-water velocity and turbulence near the
turbine generator water intakes and spillway gates. Additionally, fencing is installed around the
power plant, switchyard and spillway to limit public access to potentially dangerous areas of the
Project.
3.1.3 Proposed Changes that Might Affect the Existing Emergency Action Plan
The EAPs for both Tillery and Blewett Falls are on file with FERC and appropriate state and local
emergency service organizations. Pursuant to FERC standards, the EAP is reviewed and updated
annually to ensure that any downstream development or changes in operation are incorporated in the
plan. Progress Energy is not proposing any changes to the operation of the Project or downstream
development that would affect the existing EAPs.
3.1.4 Monitoring Devices to Detect Structural Movement
Numerous types of instrumentation and monitoring procedures are used to evaluate the performance
of the major Project structures. Tillery Dam is staffed with on-site personnel 40 hours per week
during normal business hours (Progress 2004a). During non-manned hours, the Tillery
Development is monitored and controlled remotely by personnel at Blewett Falls Dam. The Blewett
Falls Development is staffed with on site personnel 24 hours a day and seven days a week.
Regularly scheduled inspection activities at both developments include inspections of the
embankments and spillway gates and powerhouse.
^ Piezometers -Twenty-eight piezometers (19 at Tillery, and 9 at Blewett Falls) are monitored
on a quarterly basis at a minimum, if condition warrant they are checked more frequently
(ARCADIS 2004a and 2004b).
^ Weirs -Neither development utilizes weirs, however, the Tillery Development has staff
gauges in place to monitor flow in the galleries from the foundation drains, while Blewett
Falls Dam uses open collector pipes located atthe embankmenttoe to monitor seepage. These
monitoring devices are typically monitored on a quarterly basis (ARCADIS 2004a and
2004b).
^ Crack Gauges - At the Blewett Falls Plant, crack gauges are monitored in the retaining wall
at the north and south end of the spillway dam and also on the south tailrace retaining wall of
the of the intake dam. These gauges are monitored on an annual basis (ARCADIS 2004a and
2004b).
H-21

Application for License
Yadlnn-Pee Dee River Hydroelectric Project
^ Settlement and Alignment Monuments - At the Tillery Development, an alignment survey
program was implemented in 1999. Twelve monitoring stations were installed along the
concrete gravity structure. Global Positioning System (GPS) is used to monitor this facility on
an annual basis. At the Blewett Falls facility, an alignment survey monumentation system was
installed in 2000, consisting of five monitoring stations (ARCADIS 2004a and 2004b).
^ Uplift Cells -Eight up-lift cells are incorporated into the Blewett Falls intake dam and
penstock plaza. These up-lift cells are monitored on a monthly basis. While there are 28 up-
liftcells incorporated into the Tillery facility. Within the Tillery Facility, three differenttypes
ofup-lift cells have been utilized, these include manual reading using a standpipe or apressure
gauge, remotely read using electronic vibrating strip sensor, or a combination of the two
(ARCADIS 2004a and 2004b).
^ Upstream River and/or Rain Gage Stations -There are eight stream gages located in the
river basin above and below the Tillery and Blewett Falls developments (five upstream and
three downstream). Additionally, there are two rain gage stations in the areas of the two
developments (one associated with each facility). Of the gages associated with each
development, nine record hourly rain fall and two record daily rainfall (ARCADIS 2004a and
2004b).
^ Headwater/Tailwater Alarm Systems -Both facilities utilize remote monitoring equipment
which provides indication of headwater and tailwater levels and includes an audible alarm for
abnormal water level fluctuations. Monitors for both systems are displayed in the Blewett
Falls Dam control room (ARCADIS 2004a and 2004b).
^ Foundation Drains -The Tillery plant utilizes foundation drains incorporated into the
original structure to reduce up-lift pressure beneath the concrete structures. There are 57
drains located in the east abutment, powerhouse, and spillway galleries. Discharges from
individual drains are measured with a bucket and a stopwatch (ARCADIS 2004a and 2004b).
3.1.5 Safety Record
Progress Energy records all accidents that occur within the Project Boundary including those that
involve employees and the public The records specify the type and severity of the accident or
injury, the Division the employee works in, how it occurred, etc. The employee safety records are
addressed in Section 3.1.5.1 and the public safety records are addressed in Section 3.1.5.2
3.1.5.1 Employee Safety
Progress Energy's Health and Safety program includes activities focused on maintaining the
Company's core values of employee health and safety and accident prevention. The program is
based on Human Performance and continuous improvement principles. It focuses on providing a

3.2 Current Operation of the Yadkin-Pee Dee Project
The Project, which has been continuously operated since 1928, provides peaking, load-following,
and system control services. Progress Energy operates the Project in coordination with flow releases
from the upstream Yadkin Project. Daily operation ofthe two power stations is incompliance with
reservoir level requirements and FERC license required minimum stream flows of 40 and 150 cfs, at
the Tillery and Blewett Falls developments, respectively. The maximumturbine hydraulic capacity
is 17,700 cfs at Tillery and 9,200 cfs at Blewett Falls, which is the primary indicator ofthe peaking
and load-following capability of Tillery. The long-term average annual flow at the USGS
Rockingham, North Carolina gage is 7,943 cfs. The mean daily flow (1984 to 2001), from the
Tillery Development is 5,029 cfs and 7,078 cfs at Blewett Falls (Progress 2003).
In general, the Tillery Development is designed to be operated to meet peaking, load following, and
system support needs, whereas the Blewett Falls Development, is operated as apeakingfacility with
"block loading." The peaking operation at Tillery allows Progress Energy to provide electricity at
periods ofpeak demand. Tillery can also adjustto rapid changes in system needs and local transfers
of power between control areas.
Blewett Falls is operated as a "block loaded" facility, whereby the units are either operating at best
efficiency or are off. Blewett Falls acts to re-regulate discharges from Tillery, thereby reducing the
magnitude of flow fluctuations downstream of Blewett Falls.
Progress Energy's operations are affected by the operation and management of the Yadkin Project.
In accordance with Article 29 of the Yadkin Project's FERC license, the Yadkin Project must be
operated in a manner that allows Progress Energy to meet its continuous flow requirements.
Yadkin's seasonal operations are in accordance with arnle curve developedto manage water surface
elevations at High Rock Lake. A FERC Order Amending License issued in March 1968 (39 FPC
39'~ also requires Yadkin to maintain a recreational pool for High Rock Lake. Under normal and
dry conditions, this rule curve governs the general level of inflows into Narrows Reservoir and
subsequently into Lake Tillery.
3.3 History of Upgrade Programs

3.5 Record of Compliance with the Terms and Conditions of the Project License
The Projecthas been in operation since 1928 and has provided low-cost, pollution-free peaking and
load-following electrical generation throughout this time. FERC requires that Progress Energy
demonstrate its ability to operate and maintain the Proj ect in a manner which provides efficient and
reliable service. Under its stewardship, Progress Energy has a proven track record of compliance.
Progress Energy for many years worked cooperatively with local, state, and federal resource
agencies as well as other parties with a direct interest in the Project. As part of the relicensing
process, Progress Energy will work with focus groups to address several operational and resource
needs including; water quality, aquatic issues, terrestrial resources, recreation and land use, and
cultural resources.
3.6 Actions Related to the Project which Affect the Public
Progress Energy has operated the Project in a safe and responsible manner, providing a clean source
of electric power for the public's use.

3.7 Summary of Ownership and Operating Expenses that would be Reduced if
Project License were Transferred from Progress Energy
If the Project license were transferred to another entity and replacement power required to meet
Progress Energy's customer requirements must be obtained, the cost of operating and maintaining
the Project would be eliminated. Total project operation and maintenance costs are presently
projected to continue along historical trends and to track with consumer price inflation over time.
These expenses are estimated at $3,304,000 in 2005 dollars.
3.8 Annual Fees Paid for Use of Federal or Indian Lands
There are no federal or Indian lands included within the Proj ect Boundary and therefore no fees are
paid.
