2016 Minimum Flow Release and Reservoir Level Compliance Report
1.0 Introduction
On April 1, 2015, the Federal Energy Regulatory Commission (FERC) issued Duke Energy Progress, LLC (Duke
Energy) a New License for the Yadkin -Pee Dee Hydroelectric Project (Project, FERC No. 2206). This report
fulfills the annual compliance reporting requirement for minimum flow release and reservoir level required by
Articles 401(b) of the New License, as amended by FERCOs Order on Rehearing and Clarification dated October
15, 2015.
2.0 Compliance Requirements
2.1 Minimum Flow Release - Monitoring and Reporting Compliance Requirements
Sections I.B.4. and I.C.3. of the 401 Water Quality Certification (WQC) require minimum flow releases to be
measured at the United States Geological Survey (USGS) Gage No. 02129000 (Pee Dee River Near Rockingham,
NC) downstream of the Blewett Falls Development; and at USGS Gage No. 0212378405 (Pee Dee River at
Highway 731 Below Lake Tillery Near Norwood, NC) downstream of the Tillery Development.
To document compliance with minimum flow release requirements, Sections I.B.4. (Blewett Falls Development)
and I.C.3. (Tillery Development) of the 401 WQC and Article 401(b) of the New License require an annual report
to be submitted to the North Carolina Department of Environmental Quality U Division of Water Resources
(NCDEQ-DWR) by March 31 of the following year.
The annual report also requires documentation of all periods where a U true-up0 was required, as well as how and
when the U true-upU took place. Sections I.B.4. and I.C.3. define the � true -ups procedure as follows: � To the
extent practicable, Progress Energy [now Duke Energy Progress, LLC, (Duke Energy)] will 0 true-upU minimum
flows monthly; that is, flows falling below the minimum shall be offset by flows greater than the minimum
(during minimum release periods) in the same month and for a reasonably equivalent amount of time. If any
instances of recorded lower -than -required minimum flows are not properly compensated for in the month they
occur, such compensation will occur as soon as practicable in the next month, but no later than the 15'h day of that
month.0
Section I.A. of the 401 WQC specifies that the requirement to meet the minimum flow regime for the Tillery and
Blewett Falls Developments is contingent upon Cube Yadkin Generation LLC (Cube Yadkin)' releasing
minimum flows, on a daily average basis, from Falls Dam to Lake Tillery as follows:
Feb 1 to May 15: 2,000 cfs
May 16 to May 31: 1,500 cfs
Jun 1 to Jan 31: 1,000 cfs
Cube Yadkin received the New License for the Yadkin Project (FERC No. 2197) on September 15, 2016 and
began releasing the daily average minimum flow release to the Tillery Development in mid-November, 2016.
2.1.1 Blewett Falls Development - Minimum Flow Release Requirements
Section LB. 1. of the 401 WQC requires continuous minimum flow releases measured at US GS Gage No.
02129000 downstream of the Blewett Falls Development as follows:
Feb 1 U May 15: 2,400 cfs
May 16 U May 31: 1,800 cfs
Jun 1 U Jan 31: 1,200 cfs
Article 403 of the New License was revised with the FERC Order on Rehearing and Clarification issued on
October 15, 2015 to read as follows:
The licensee must provide minimum flows required by sections LB.1 (Blewett Falls Development) and LC.1
(Tillery Development) of North Carolina Division of Water QualityUs (DWQ) water quality certification in
Appendix A. If the flows released from the Yadkin Projectfls Falls development are less than the flows specified in
section LA of North Carolina DWQOs water quality certification, the licensee must release from the Blewett Falls
development 1.2 times the average daily flow released on the preceding day from the Yadkin ProjectOs Falls
development, or 925 cfs, whichever is higher.
Section I.B.4. of the 401 WQC specifies that minimum flow release requirements for the Blewett Falls
Development shall be presumed to have been met if flows at USGS Gage No. 02129000 are within 5% of the
required minimum flow releases, as long as the U true-up0 procedure has been followed.
2.1.2 Blewett Falls Development - Flow Adjustments to Enhance Fish Spawning
Section I.B.2. of 401 WQC requires flow adjustments to enhance fish spawning to begin in the year following
issuance of the New License, or in the spring of 2016. This requires flow adjustment operations to occur at
' Order Approving Transfer of License for the Yadkin Hydroelectric Project (FERC No. 2197) from Alcoa Power
Generating, Inc. (APGI) to Cube Yadkin Generation LLC (Cube Yadkin), Cube Carolinas, an affiliate of Cube Hydro
Partners issued December 13, 2016, 157 FERC 162,188 (License Transfer Order).
certain times between February 1 and May 15, in a manner intended to enhance fish spawning conditions
downstream of Blewett Falls Development. The requirements of the flow adjustment operations are as follows:
0 Flow adjustment operations shall occur between February 1 and May 15.
The specific time periods in each year will be decided upon by resource agencies, Duke Energy, and
Cube Yadkin U collectively, the U Spawning Flow Management Team.0
Periods of flow adjustment operations shall be chosen by the Spawning Flow Management Team
(SFMT) based on interpretation of relevant factors that might include, but are not limited to, water
temperature and weather data, projected inflow conditions, and observations of fish spawning
behavior. If the option of five 5 -day periods is implemented, two of these periods must occur
between April 15 and May 15.
If a period of intermediate inflow to the Blewett Falls Reservoir occurs (flows in the range of 3,000 to
6,000 cfs), Progress Energy will manage releases at the Blewett Falls powerhouse as follows:
1) If unregulated tributary inflow to the Pee Dee River above Blewett Falls (particularly from the
Rocky River) changes significantly during a designated flow adjustment operation period,
Progress Energy can respond to these changes in flow as needed to manage reservoir operations
by increasing or reducing the number of turbines in operation without consideration to the limits
described below in (2) through (5). This would still be considered a flow adjustment period.
2) Except as identified in (1) above, the upramp time of each turbine at Blewett Falls will be no
less than 30 minutes from off-line to full gate.
3) Except as identified in (1) above, the downramp time of each turbine at Blewett Falls from full
gate to off-line will be in accordance with the following guidelines:
After the first operating unit is taken off-line, the second operating unit to be taken
off-line shall not be taken off-line for at least two hours after the first operating unit
was taken off-line.
ii. After the second operating unit is taken off-line, the third operating unit to be taken
off-line shall not be taken off-line for at least four hours after the second operating
unit was taken off-line.
iii. After the third operating unit is taken off-line, the fourth operating unit to be taken
off-line shall not be taken off-line for at least six hours after the third operating unit
was taken off-line.
4) On the first day of any flow adjustment operation period, Blewett Falls must commence such
related operations no later than 8 a.m. to still be considered as a full day of flow adjustment
operation.
5) On the last day of any flow adjustment operation period, Blewett Falls units can begin to be taken
off-line no earlier than 4 p.m. By example, the schedule below would be considered a full day of
a designated flow adjustment operation period if it were the last day of such period:
4 PM U go from 5 units to 4 units
ii. 6 PM U go from 4 units to 3 units
iii. 10 PM 0 go from 3 units to 2 units
6) If the five 5 -day flow adjustment operation periods are chosen in any given year, each period
shall begin on a Monday morning and end on a Friday evening.
7) If the one 14 -day and one 10 -day period is chosen in any given year, the actual dates shall be such
as to minimize the number of weekend days within the 14 -day period. For the 10 -day period,
there will be no more than 2 weekend days.
All decisions to be made by the SFMT, as outlined in this section, shall require consensus as specifically
defined as follows in the Comprehensive Settlement Agreement:
A resolution based on consensus shall have either the unanimous support of all Parties, or at least
no opposition from any Party. If a Party has no objection to the resolution, but does not
specifically endorse it, the lack of opposition shall be considered to be support of the resolution.
Duke Energy will prepare an annual report of the operations of the Blewett Falls Development during the
Flow Adjustment Operation periods, consisting of meeting notes, flow records from streamflow gages,
and plant operations. The operations of the Tillery Plant during the Flow Adjustment Period will be
coordinated by Duke Energy and subject to dispatch by Duke Energy in accordance with its system needs.
2.1.3 Tillery Development - Minimum Flow Release Requirements
Section I.C.1. of the 401 WQC requires a year-round minimum flow release of 330 cfs, except for an eight-week
period beginning between March 15 and March 22, when minimum flow release will not be less than 725 cfs, to
enhance spawning of American shad. The eight-week minimum flow of 725 cfs is contingent upon passage of
American shad above the Blewett Falls Development. Passage of shad is currently scheduled to begin in the
spring of 2020 with passage above the Tillery Development.
Section I.C.3. of the 401 WQC specifies that minimum flow release requirements for the Tillery Development
shall be presumed to have been met if flows at USGS Gage No. 0212378405 are within 5% of the required
minimum flow releases, as long as the � true-up0 procedure has been implemented.
2.2 Reservoir Water Level Requirements - Compliance Monitoring and Reporting
Section II.C. of the 401 WQC requires submittal of an annual report on reservoir water level compliance to the
NCDWR, including reporting of hourly reservoir levels recorded at the Tillery and Blewett Falls Developments.
4
Maintenance of minimum flow releases takes precedence over reservoir water level regimes (Section I.B.1. of the
401 WQC).
2.2.1 Blewett Falls Development - Reservoir Elevation Requirements
Section II.A. of the 401 WQC requires that, when inflows to Blewett Falls Reservoir are less than approximately
7,400 cfs, reservoir water levels shall be maintained between 172.1 and 178.1 ft (no lower than 6 ft below full
pond), except during system emergencies or when the Low Inflow Protocol (LIP) (described in Appendix B of the
WQC) is invoked. An additional 2 feet of drawdown to elevation 170.1 ft is allowed in the event flashboards
require replacement.
In addition, during bass spawning season, April 15 to May 15, water level fluctuations are limited to 2 feet, unless
flashboards fail or additional reservoir storage is necessary to meet minimum flow release requirements.
2.2.2 Tillery Development - Reservoir Elevation Requirements
Section II.B.1. of the 401 WQC requires a seasonal reservoir water level management regime for the Tillery
Development as follows:
Time Period
Condition
Reservoir Elevation Range (ft)
Dec 15 -Mar 1
Normal
275.2 0 278.2 (3 ft below full pond)

Section II.13.2. specifies that once every five years, a drawdown of up to 15 feet will be scheduled within the
September 15 to December 15 timeframe to perform routine maintenance and gate testing.
3.0 2016 Compliance with Minimum Flow Release Requirements
3.1 Blewett Falls Development
Flow release data recorded January 1 through December 31, 2016, for Blewett Falls Development as measured at
15 -minute intervals at USGS Gage No. 02129000 are contained in the Excel file Yadkin Pee Dee Project
Minimum Flow Release Data 2016.xlsx, submitted with this report. Daily minimum flow releases and flow
release compliance limits are plotted in Figure 1. Daily minimum and maximum flow releases are reported in
Appendix A (Table 1). As required in Section I.B.4. of the 401 WQC, flow release data from the USGS
monitoring gage at Rockingham (USGS Gage No. 02129000) are made available to the public at the following
website: http:Hwaterdata.usgs.gov/nwis/uv?site no=02129000.
Article 403 of the New License (as revised by FERC in the Order on Rehearing) allows the minimum flow release
from the Blewett Falls Development to be reduced at times when the upstream Yadkin Project (FERC No. 2197)
is releasing less than the minimum release required by their New License. More specifically, the Blewett Falls
minimum flow release should equal 1.2 times the average of the release for the preceding day from the upstream
Yadkin ProjectOs Falls Development but at no timeless than 925 cfs. Duke Energy implemented this modified
flow release on two different occasions when the flow release from Falls Development was less than the
minimum daily flow release requirement of the Yadkin ProjectOs New License. There were additional days when
the Falls Development released less than the minimum flow release required by the New License, but Duke
Energy did not modify the Blewett Falls minimum flow release. The table below summarizes days when the
modified flow release was implemented.
Table 1: Implementation of Modified Minimum Flow Release at Blewett Falls Development
Flow releases from Blewett Falls Development as measured at USGS Gage No. 02129000 deviated from the
normal minimum flow release requirement on July 5, 2016, between 16:45 and 21:15 EDT (for 17 of the 19
observations). However, flow release remained within 5% of the required minimum flow release requirement
(i.e., above 1140 cfs). This requires the 0 true-up0 procedure where flows falling below the minimum requirement
are required to be offset by flows greater than the minimum requirement in the same month and for a reasonably

Flow releases from Blewett Falls Development as measured at USGS Gage No. 02129000 deviated from the
normal minimum flow release requirement on July 5, 2016, between 16:45 and 21:15 EDT (for 17 of the 19
observations). However, flow release remained within 5% of the required minimum flow release requirement
(i.e., above 1140 cfs). This requires the 0 true-up0 procedure where flows falling below the minimum requirement
are required to be offset by flows greater than the minimum requirement in the same month and for a reasonably
equivalent amount of time. From 16:45-21:15 EDT, the flow release averaged 1167 cfs, ranging from 1140 to
1180 cfs; thus the deviation averaged 33 cfs below the required minimum flow release. On July 6, from 0:00-4:30
EDT, the 4.5 -hour period immediately following the deviation, the flow release ranged from 1290 to 2410 cfs,
averaging 1514 cfs; 314 cfs above the required minimum flow release. Thus the deviation from minimum flow
was U trued-up0 the following day, fulfilling the requirement that 0 true-upU occur within the same month. This
event was in compliance with License requirements for minimum flow releases.
The final minimum flow deviation at the Blewett Falls Development occurred on November 28, 2016. On
October 27, 2016, FERC and the resource agencies were notified of this deviation due to a planned outage at the
Blewett Falls Hydro Station.2 FERC acknowledged this notification on December 12, 2016 and asked that a
supplemental report be submitted describing any license deviations.3 Duke Energy submitted the supplemental
report on January 13, 2017.4 FERC responded to the supplemental report that the license deviations would not
be considered a violation of the minimum flow release requirements.

3.2 Flow Adjustments to Enhance Fish Spawning
Implementation of flow adjustments to enhance fish spawning was required in the spring of 2016. A
meeting was held on January 22, 2016, with the SFMT to review the requirements of the spawning flow
adjustments associated with the New License. Duke Energy presented a plan for implementation of the
requirements and the SFMT reached a consensus decision on how the operational adjustments should be
implemented. The meeting minutes, flow records from USGS Gage No. 02129000, and plant operations
are included in Appendix B of this report.
Beginning in January of 2016, the Blewett Falls Development underwent a series of outages for
modifying the station for remote operation. This resulted in at least two of the hydro units being out of
service in the spring and the remaining four units were used to provide the minimum flow requirement.
Because of this, the strict application of the spawning flow adjustment requirements in the License would
not have been required because the four operational units were not taken off-line.
Because the goal of the flow adjustment operations is to slow the recession time of the flow releases
downstream of Blewett Falls Development, the SFMT agreed that a 3 MW reduction in generation per
hour (approx. 1030 cfs) would be sufficient to slow the flow release recession time when inflow into
Blewett Falls is between 3000 cfs and 6000 cfs. Units 1 and 2 were out of service during the spring and
the minimum flow of 2400 cfs was provided with generation from Units 3-6. The SFMT agreed to
implement the one 14 -day flow adjustment period on April 11 - 24, 2016, and one 10 -day period on May
2-11,2016.
The SFMT also agreed that determination of the inflow into Blewett Falls Development each day would
be based on the planned generation from the upstream Tillery Development. Generation from the Tillery
Development between 375 megawatt -hours (MWh) and 750 MWh, results in a daily average inflow into
Blewett Falls between 3000 and 6000 cfs. Generation from Tillery is determined daily and is based on
inflow from the Yadkin ProjectOs Falls Development.
A review of the results of operations during the spawning flow adjustment periods was provided at the
Diadromous Fish Passage Plan Agreement Resource Management Team (RMT) Meeting on January 10,
2017 (see Appendix B). During April 11 � 24 (the 14 -day adjustment period) inflow into Blewett Falls
Development, as determined by generation from the Tillery Development, was between 3000 and 6000
cfs on April 11-13 and April 18-21 or 7 of the 14 days. During May 2-11 (the 10 -day adjustment period)
inflow occurred between 3000 and 6000 cfs on May 2 and May 9-11 or 4 of the 10 days (see Table 2
below). In 2016, the criteria for adjustments were in effect 44% of the time and only on weekdays.
Graphs depicting the flow releases and station generation during the spawning flow adjustment periods
were presented to the SFMT on January 10, 2017. The resource agencies thought it would be more
informative to present the change in the water level stage or gage height at USGS Gage No. 02129000
rather than the change in river flow. This would provide a better understanding of the flow recession
times associated with the changes in operations (see Figures 2-5). Appendix B, Table 2 and Table 3
01
provide the hourly average flow release and stage height from USGS Gage No. 02129000 along with
hourly generation during the spawning flow adjustment periods.

3.3 Tillery Development
As required in Section I.C.3., flow release data from the USGS Gage near the State Highway 731 Bridge (USGS
Gage No. 0212378405) is made available to the public at the following website:
http://waterdata.usgs.gov/nwis/uv?site no=0212378405.
Flow release data from the Tillery Development, as measured every 15 minutes at USGS Gage No. 0212378405
are contained in the Excel file Yadkin Pee Dee Project Minimum Flow Release Data 2016.xlsx, submitted with
this report to fulfill the requirement for annual reporting of these data.
Data is not present in USGS data on January 1-2, 2016, due to a high inflow event. Data was also reported as
missing on December 3W 31, 2015 associated with the same high inflow event (see 2015 Flow and Reservoir
Level Data Report for the Yadkin -Pee Dee Project). Hourly estimated flow releases on January 1-2 are based on
plant generation records along with the settings on the spillway gates. These data are also included in the Excel
file.
Daily minimum flow releases recorded January 3 through December 31, 2016, are plotted with minimum flow
compliance limits in Figure 6. Daily minimum and maximum flow releases are also reported in Appendix A,
Table 2. From January 1 through December 31, 2016, Tillery flow releases as measured at the USGS Gage No.
0212378405 and calculated from generation records were in compliance with minimum flow release requirements
of the New License. Because the minimum flow release did not fall below the required release, there were no
periods of time when the true -up procedure was required.

4.0 Compliance with Reservoir Level Requirements
4.1 Blewett Falls Development
Blewett Falls Reservoir was operated in compliance with the required reservoir level regime from January 1
through December 31, 2016. Reservoir water levels measured on an hourly basis did not fall below the year-
round minimum elevation of 172.1 ft or 6 feet below full pond. Hourly reservoir levels recorded January 1 U
December 31, 2016, are plotted in Figure 7 and provided in the Excel file Yadkin Pee Dee Project Reservoir
Elevation Data 2016.xlsx, submitted with this report. Daily minimum and maximum reservoir levels are provided
in Appendix A, Table 3.
Blewett Falls Reservoir water level was 174.9 ft (96.8 ft local datum or 3.2 ft below full pond) at 0:00 EDT on
April 15, 2016, at the beginning of the bass spawning season. Section II.A. of the 401 WQC requires that
reservoir level changes from April 15 to May 15 be limited to 2 ft: thus the minimum compliance reservoir level
during the 2016 bass spawning season was 172.9 ft (94.8 ft local datum or 5.2 ft below full pond). The minimum
level observed during this period was 173.0 ft (94.9 ft local datum or 5.1 ft below full pond), indicating that
reservoir levels were in compliance with the lower limit throughout the specified bass spawning season.
Reservoir level data was measured hourly, generally resulting in 24 measurements per day (Appendix A, Table 3).
Data was collected by station personnel as well as electronically recorded in the Plant Information (PI) database
through July 3, 2016. This provided a second dataset that could be used to supplement the electronic dataset
when monitoring equipment malfunctions resulted in missing data. Station personnel discontinued data collection
and hourly reservoir level data was recorded electronically only from July 4- December 31, 2016. During this
time, monitoring sensor malfunctions occurred on 8 days (see table below) with an overall recovery rate of
99.6%.

4.2 Tillery Development
Tillery Reservoir level was operated in compliance with the requirements specified in the New License from
January 1 through December 31, 2016 with the exception of December 3 and 4, 2016. Hourly reservoir levels for
the Tillery Development measured by Duke Energy at the forebay for the period January 1 � December 31, 2016,
are plotted in Figure 8 and provided in the Excel file Yadkin Pee Dee Project Reservoir Elevation Data 2016.xlsx.
Daily minimum and maximum reservoir levels are provided in Appendix A, Table 3.
Tillery Reservoir water elevation was 277.95 ft above mean sea level (or 99.75 ft local datum or 0.25 ft below full
pond) on April 15, 2016 at 0:00 hours, the beginning of the bass spawning season (April 15 U May 15). The
license requires that the elevation be maintained within 1.5 ft of where it was measured on April 15"; Thus, the
compliance limit for minimum level during the bass spawning period was 276.45 ft (98.25 ft local datum or 1.75
ft below full pond). The minimum hourly reservoir elevation observed during this period was 276.83 ft (98.63 ft
local datum), indicating that levels were in compliance throughout the specified bass spawning season.
Reservoir level data was measured hourly, generally resulting in 24 measurements per day (Appendix A, Table 3).
Data was collected by station personnel as well as electronically recorded in the Plant Information (PI) database
through July 3, 2016. This provided a second dataset that could be used to supplement the electronic dataset
when monitoring equipment malfunctions resulted in missing data. Station personnel discontinued data collection
and hourly reservoir level data was recorded electronically only from July 4- December 31, 2016. During this
time, monitoring sensor malfunctions occurred on 3 days (see table below) with an overall recovery rate of
99.9%.

On December 3 and 4, 2016, the reservoir level for Tillery was lower than the minimum allowed by the New
License. This was necessary to support a station outage at the Blewett Falls Development downstream. FERC
and the resource agencies were notified of the deviation from reservoir level requirements at Tillery on October
27, 2016.6 FERC acknowledged this notification on December 12, 2016 and asked that a supplemental report be
submitted describing any license deviations.' Duke Energy submitted the supplemental report on January 13,

Objective: Develop a plan for implementing the Spawning Flow Adjustment Period as defined
in the 401 Water Quality Certification and Appendix A of the New License
Summary:
A previous discussion of this license requirement was held at the December 2, 2015 Resource
Management Team (RMT) meeting where Styer and Stuart reviewed the license requirements
with the attached PowerPoint presentation (see Attachment 1). All of the above attended with
the exception of Fred Tarver (NCDEQ) and Bryn Tracy (DWR). Styer and Stuart updated
Tarver and Tracy in a conference call on 1/21/2016. At the December 2, 2015 RMT meeting,
attendees asked to see the Flow Duration Curves for the USGS Gage at Hwy 74 Bridge (USGS
Gage #02129000) and for DEP to provide information graphically to help better understand the
issues associated with operation of the plant during the flow adjustment periods.
Attachment 2 - Blewett Falls Spawning Flow Adjustment Operations for 2016, Attachment 3 -
2016 Spawning Flow Reduction Excel Spreadsheet and Attachment 4 0 Flow Duration Curves
for were provided to the SFMT on Friday 1/15/2016 to review prior to this meeting.
Styer reviewed the Spawning Flow Adjustment requirements of the license and presented the
plan for spring 2016 (Attachment 2). Because Units 1 and 2 will be out of service during the
spring due to automation work, Units 3-6 will provide the minimum flow of 2400 cfs as
described in Attachment 2 and will stay on line over the entire period. Therefore, no units will
be taken off-line in 2016 from March 1St U May 15th. The strict application of the language in
the license would result in this process not applying to the operations of Blewett Falls this spring.
However, to show a good faith effort at meeting the intent of this license requirement, DEP has
agreed to adjust reductions in generation from the four units that will be in service in the spring
of 2016.
Styer then reviewed the 2016 Spawning Flow Reduction Excel Spreadsheet (Attachment 3)
developed to show how the inflows over several days in April 2015 would be adjusted, given
those same conditions in 2016. The goal of the adjusted generation reductions is to slow the
recession time in flow downstream of Blewett Falls Dam. The SFMT agreed with the 3 MW
reduction per hour (approx. 1030 cfs) that will be made when inflow into Blewett Falls is
between 3000 cfs and 6000 cfs. The group also agreed that after this first year of implementation
and with the completion of station automation, the operating scenario for 2017 will need to be
revisited.
The SFMT then discussed the timeframe (in 2016) for when this flow adjustment period should
be implemented. The Flow Duration Curves (Attachment 4) were reviewed and showed that
March is the least likely month to have sustained inflows between 3000 and 6000 cfs while May
was the most likely month to have sustained inflows at those levels. There was also discussion
about the one 14 -day and one 10 -day periods vs the five 5 -day periods. The requirement to
separate the five 5 -day periods by one week each would result in a 9 week timeframe for
implementing this program. Goudreau provided the Fish Species Spawning and Rearing
Summary Figures from the license application (see Attachment 5) and page 3 illustrates the
majority of the species targeted typically spawn in the April and May timeframe. Therefore, the
group decided to implement the one 14 -day and one 10 -day period and chose to target mid-April
and early May.
Tentative plans are to start the 14 -day period on April 11th and the 10 -day period on May 2"d
DEP will install a new thermistor in the tailrace to monitor temperature and will keep the SFMT
informed of the results. Adjustments can be made to the schedule if needed. SCDNR will also
keep us informed on the American shad spawning activity in Winyah Bay. DEP will plan to
notify the dispatch operations by the end of March with the planned schedule.
The SFMT reached a consensus decision on implementing the 2016 Spawning Flow Adjustment
protocols and the meeting was adjourned.

Flow Adjustment Operations
Start time is chosen by the SFMT based on
water temperature, weather data, projected
inflow conditions, observations of fish
spawning behavior, etc.
Other specification on separation of weeks,
minimizing weekends, changes in inflow,
during flow adjustment operations, etc.
All decisions shall require consensus
(unanimous support of all Parties, or at least
no opposition from any Party)
1l.
Annual Report and Evaluation
Duke Energy will prepare an annual report
meeting notes, flow records, plant operations, USGS
gage data, etc.
After five years of Flow Adjustment
Operations, the SFMT shall evaluate and
develop recommended changes for
consideration by the resource agencies and
Duke Energy.
Reevaluation at 5 -year intervals may occur if
determined necessary and if agreed to by the
Spawning Flow Management Team.

Blewett Falls Spawning Flow Adjustment Operations for 2016
Generation Parameters
• Units 1 and 2 will be out of service
• Unit 3
o Minimum load of 0.5 MW (172 cfs)
o Economy load — 3.5 MWs (1201 cfs)
o Full load— 4.2 MWs (1441 cfs)
• Units 4-5-6
o Minimum load per unit — 2.0 MWs (— 686 cfs)
o Economy load per unit — 4.2 MWs (— 1441 cfs)
o Full load per unit — 5.3 MWs (— 1818 cfs)
• Max generation available in spring of 2016 is approximately 6900 cfs (all 4 available
units at full load)
Unit Operation (for either one 14- day and one 10 -day period or five 5 -day periods) during
spring spawning flow adjustment periods when inflow into Blewett Falls is between 3000
cfs and 6000 cfs
• Minimum Flow of 2400 cfs (7 MWs) provided by the following combination of unit
generation (Note: 1 MW — 343 cfs)
o Unit 3 - 1 MW
o Units 4, 5, 6 - each at 2 MWs
• Increase in generation would occur one unit at a time (from minimum flow setting to
economy load) resulting in 5,500 cfs (16 MWs). Additional increases to full load would
occur as needed (but would likely be required only during inflow events above 6000 cfs).
• Generation would decrease at no more than 3 MWs (<-1030 cfs) per hour back to
minimum flow setting.

Diadromous Fish Passage Plan Agreement
Resource Management Team (RMT) Meeting
Tuesday, January 10, 2017
Morrow Mountain State Park, Albemarle, NC
10:00 AM — 2:30 PM
Attendees:
Duke Energy — Alan Stuart, Jason Brown, Tami Styer, Justin Dycus, Lynne Dunn
NC Wildlife Resources Commission (WRC) — Chris Goudreau,
NC Department of Environmental Quality, Division of Water Resources — Fred Tarver
SC Department of Natural Resources (DNR) — Bill Post, Chad Holbrook,

National Marine Fisheries Service (NMFS) — Fritz Rohde,
Alcoa Power Generating, Inc. (APGI) — Mark Gross
Develop 2017 Spring Spawning Flow Release Plan
The goal of the discussion was to develop a plan by February 1, 2017 for implementation of the
Spawning Flow Adjustments as required by the New License and the 401 Water Quality
Certification (WQC). Styer presented the information in Enclosure 1 which addressed the
requirements of the program as well as the results of the implementation of the program in the
Spring of 2016.
Because there were only four units available for generation in 2016 due to the automation of the
plant, the Spawning Flow Management Team (SFMT) had agreed to a 3 MW reduction per hour
when in the periods selected for flow adjustments. The results showed MW reduction along with
flow releases as measured at the USGS Gage No. 02129000. Goudreau suggested that it might
be more informative to also show the change in the water level stage at the USGS Gage rather
than simply in the change in the river flow. Styer agreed to add this information to the annual
report which will be submitted to FERC and the SFMT along with the annual Water Quality
Report (due April 15, 2016).
Based on the results of the adjustments in 2016 and the time the criteria for adjustments were in
effect (44% of the time and only on weekdays), the SFMT agreed to test the five 5 -day periods in
2017. Each 5 -day period will be separated by a week of no flow adjustments. The five weeks of
flow adjustment will be as follows: March 13-17, March 27-31, April 10-14, April 24-28, and
May 8-12. All six units should be available for generation in the spring and adjustments in the
flow releases during the five weeks identified above will be made as defined in the 401 WQC
requirements.
American Shad/American Eel Reports
Stuart issued the American Shad and American Eel 2016 draft reports to the RMT in December
2016 and requested comments back by Jan 23, 2017. Stuart stated that comments had been
received from Goudreau and asked if the rest of the team had comments or questions. The team
stated that they would submit any additional comments by Jan 23ra
Biological Opinion/Sturgeon Protection Plan Monitoring
Stuart provided a brief update on the status of the installation of the USGS gage at Jones Creek
Shoals. Duke is currently waiting on a FEMA determination that the fence, located around the
monitoring structure on the bank of the river, will not contribute to an increase in the level of
flooding. Other than that, we received the Jurisdictional Determination from the US Army
Corps of Engineers that the project did not require a 404 permit. Once the FEMA No -rise
Certification is received, the structure can be installed. The requirement to monitor for dissolved
oxygen and temperature begins May 1 — November 30th. Styer submitted a request to FERC for
an extension to the installation date requirement of Dec 31, 2016 (which FERC approved on Jan
11, 2017).
Duke also reported that a plan was in place in the fall of 2016 to complete the field work for
verifying the IFIM modeling and conducting the baseline habitat assessment required by the
BiOp. Because of the dry conditions, there was a concern about maintaining the 2400 cfs
continuous flow required to collect the field data and the affect that would have on the Blewett
Falls Lake level. For that reason, the study was postponed from the winter of 2016. This will be
scheduled again early in 2017.
Post presented the information in Enclosure 2 on the status of the tagging efforts for the Atlantic
and shortnose sturgeon. Tagging efforts were impacted by Hurricane Matthew's effects on the
Waccamaw and Pee Dee Rivers in late 2016. He stated river levels have returned to normal,
tagging is ongoing and the project's goals are to attemp to tag the target number of fish for 2017.
American shad Downstream Passage Design(s) Review
Stuart reviewed the schedule for the downstream passage design. The flashboards on the
Blewett spillway have been repaired and the ADCP data required for the hydraulic modelling for
downstream design will be collected during the week of January 23, 2017. Modeling will
require 2 to 3 weeks and this information will be necessary to complete the 30% design. Duke
will forward the completed 30% design to the RMT for review and comment when complete.
American Shad Upstream Passage Design Review
Stuart issued the 30% design of the upstream passage structure to the RMT on January 5, 2017
(see Enclosure 3). Duke requested comments from the RMT by February 1St. Stuart reviewed
the responses developed by John Truebe (Lakeside Engineering) to comments received from
Bjorn Lake (NMFS Fishway Engineer) following his review of the upstream conceptual design
(see Enclosure 4). The schedule currently has completion of the upstream passage facility in
January of 2019 (four years after issuance of the new license). This first year will be a "shake-
down" year and passage in the spring of 2020 will be considered the first official year of passage.
The Fish Passage Agreement (Agreement) is written to require passage of the shad collected
during the spring of 2020 to be passed above Tillery for four years and then above Blewett Falls
for the next four years. Stuart stated that the option for releasing fish into Tillery was probably
limited to Morrow Mountain State Park boat ramp and wondered if the RMT thought the travel
time could impact the heath of the fish. The current RMT members did not participate in the
development of the Agreement and it is not clear as to why the first passage is above Tillery as
opposed to Blewett Falls. Goudreau stated that the Agreement identifies estimated carrying
capacities (Tillery is 17,000 and Blewett Falls is 150,000) and the requirement to pass fish above
Tillery first could have been related to the expectation that fewer fish would be caught in the first
years. Post stated that it could have been similar to the reasoning at Santee River systems where
it was thought that passing the fish to the highest point would encourage imprinting and
recruitment in the future. Goudreau stated that it makes more sense to go above Blewett Falls
first. Rohde stated it is NMFS philosophy to go above the first dam first and to pass them above
the 2nd dam when they reach it. Goudreau noted that the fish passage prescription allows the
RMT to decide which reach should first be stocked.
Duke agreed to develop a plan tagging up to 50 shad to document where fish respond to stocking
in Blewett Falls lake. Duke will provide an aerial map of Blewett Falls at the next meeting
identifying potential location for receivers and then work to develop specifics on the study
methodology in detail for RMT approval.
Meeting adjourned at 2:00 PM
