2022 Water Quality Compliance Report

1.0 Background
On April 1, 2015, the Federal Energy Regulatory Commission (FERC; Commission) issued Duke Energy
Progress, LLC (Duke Energy) a New License (License) for the Yadkin-Pee Dee Hydroelectric Project
(Project, FERC Project No. 2206). License Article 402 approved Duke Energy’s Dissolved Oxygen
Compliance Implementation Plan (Compliance Plan), filed with FERC on January 20, 2012, to meet the
water quality monitoring requirements outlined in Sections III.A.2 and III.B.2 of the 401 Water Quality
Certification (WQC) issued by the North Carolina Division of Water Resources (NC DWR).

This report fulfills the annual water quality compliance reporting requirement outlined in the WQC for
monitoring conducted in 2022. The data reported here conform to requirements outlined in the
Compliance Plan, Section 8.0 – Compliance Monitoring and Reporting (Progress Energy Carolinas, Inc.
2012).

2.0 Compliance Monitoring
As required in the Compliance Plan, the following parameters were measured at 15-minute intervals from
May 1 through November 30, 2022, in the tailwaters of the Tillery and Blewett Falls Developments:

• Dissolved oxygen (DO), mg/L
• Water temperature, oC
• Gage height (river stage), feet

Measurements were carried out by the United States Geological Survey (USGS) as required by Section
7.0 of the Compliance Plan, at the following locations:

Development USGS Station Number USGS Station Description
Tillery 0212378405 Pee Dee River at Highway 731 below Lake
Tillery near Norwood, North Carolina
Blewett Falls 0212880025 Pee Dee River below Powerhouse Dam near Pee
Dee, North Carolina

3.0 Compliance Reporting
Results reported here are based on approved data provided to Duke Energy by USGS after their final
quality assurance review, as specified in Section 8.0 of the Compliance Plan. This report and the
associated Excel file provide the following results for data collected May 1 through November 30, 2022:

• DO and water temperature recorded at 15-minute intervals
• Daily minimum, average, and maximum DO values
• Daily minimum, average, and maximum water temperature values

Calculations for percent DO saturation (% saturation) along with DO, water temperature, and gage height
(river stage) data measured at 15-minute intervals at the USGS monitoring locations described above are
reported in the Excel file associated with this report: Yadkin-Pee Dee Project Water Quality Data
2022.xlsx.

Daily minimum, average, and maximum DO concentration and water temperature data are reported in
Table 1 for the Tillery Development and in Table 2 for the Blewett Falls Development. Daily minimum
and average DO values are graphed for the Tillery Development in Figure 1 and for the Blewett Falls
Development in Figure 2. Daily minimum, average, and maximum water temperature values are graphed
in Figure 3 for the Tillery Development and Figure 4 for the Blewett Falls Development.

Data Recovery
Water temperature, DO and gage height were measured at 15-minute intervals, generally resulting in a
total of 96 observations per day. Overall recovery rates for approved continuous DO monitoring data
collected during the 2022 period was 95.8% for the USGS station at Blewett Falls Development (USGS
No. 0212880025) and 99.1% for the USGS station at Tillery Development (USGS No. 0212378405).

Please note for the period October 5 (starting at 12:15 hrs.) through October 13, 2022 (ending at
12:00 hrs.), the USGS did not include the collected DO data for Blewett Falls Development
during this period as it fell outside of its calibration correction procedure (± 2 mg/L) due to
heavy biofouling of the DO sonde (Table 2 and Figure 2). The DO sonde was cleaned and
calibrated and replaced with another sonde during an onsite visit by USGS personnel on October
13, 2022 (see Table 3). After examination of the data, the USGS omitted the data for the 7-day
period. Examining the DO trending just prior to and after the omitted data dates showed DO
3

values were well above the instantaneous and daily average water quality standards (see
Figure 2).

The USGS installed new In-Situ Aqua TROLL 600 Multiparameter sondes equipped with Aqua TROLL
0063450 RDO sensors for compliance water quality monitoring in April 2021. This equipment replaced
the previous sondes deployed at the monitoring sites, as specified in Section 7.2 of the Compliance Plan
(i.e., YSI 600 OMS V2 sondes equipped with YSI 6150+ ROX Optical DO Probes).

Table 3 documents the dates during the monitoring period when the USGS performed routine calibration
and maintenance of the field instrumentation.

3.1 Compliance with Water Quality Standards
The WQC issued by NC DWR (Appendix A of the New License) specifies that DO concentrations in
Project tailwaters will comply with the applicable North Carolina water quality standards which are as
follows (NCDENR-DWQ 2007):

Standard for instantaneous DO concentration, minimum: 4.0 mg/L
Standard for daily (24-hour) average DO concentration, minimum: 5.0 mg/L

Daily Average DO Standard
During the monitoring period (May 1 - November 30, 2022), the daily average DO concentrations in the
Tillery Development and Blewett Falls Development tailwaters remained above the state standard of
5.0 mg/L (Figures 1 and 2).

Instantaneous DO Standard
During the monitoring period (May 1 - November 30, 2022), the instantaneous DO concentration in the
Tillery Development and Blewett Falls Development tailwaters remained above the state standard of
4.0 mg/L (Figures 1 and 2).

2022-07-21 08:07-09:49 Troubleshoot loss of GH/DO/temp from site and loss of comms to Duke,
found error on sl3 showing gps antenna short circuit and unable to get
any mmts, removed sl3-1808323, deployed sl3-1807119, removed
LiFePO battery deployed AGM battery at dcp gage and sonde gage
locations, replaced battery cables to bus bar at dcp gage, still had gps
antenna short circuit on new sl3, replaced gps antenna - now getting
good gps, able to get GH but unable to get DO/temp, found issues with
riot titan gateway radio - broken solder on chip/board - Keith attempted
to re-solder - did not work, removed lt15g-00046 and lt15x-00038, put
sl3- 1705393 in sonde gage with gps puck to log QW data while going
back to office for equip, removed sl3- 1705393, deployed susdim-
1704195, deployed susdis-1612221, got sdi12 radios to work and data
come into sl3, confirmed good DO values seen by RROC and dam.
2022-07-26 08:54-12:39 Move main gage from roadside to bridge.. radar moved down stream
near qw gage. new wwg installed. quick set of levels to set new wwg chk
bar.new ds chkbar set to 40.294 from levels. new wwg 3.71 at1205. old
wwg reads 3.65+-0/02. set rls back to old wwg per Boo. 3.65ft@1236
2022-08-09 08:38-15:06 Outine qw sonde svc/mmt 72/qw cross section, dcp battery 14.5v, 13.6v
under load, downloaded dcp data.
2022-09-16 10:10-13:30 Baro s/n = DM904, Diver s/n = DL992. Tape down from RP1 = 0.78 ft
2022-10-20 09:25-15:13 Routine service/mmt 73/QW cross section, dcp battery 14.4v (13.9v
under load), sl3 gave GPS antenna not detected error - but gps synced
good as of today - cleared and will monitor, taped diver 0.78ft (same as
last, left at 0.78ft), downloaded diver/baro/dcp data.
2022-10-21 09:09-09:54 Site visit to diagnose no DO to Duke (transmitting to AQ but erroneous
value being removed via threshold), getting -99999.00 mg/L at SL3, WT
coming in fine - suspect DO probe failure and sonde ok, dcp battery 14.4v
(13.8v under load), connecting to sonde kept giving "instrument open"
and "sensor changed" errors and DO not showing up as installed sensor
when connected direct to sonde, appears DO probe in Tillery 2 sonde
733212 failed (temp 784041, DO 812438), for ease of troubleshooting
deployed Jones Rock 1 sonde 733343 with Tillery 1 probes (temp 745909,
DO 751651), verified good DO read direct connect - at sl3 (had to reorder
parameters do param1, temp param 2, sonde bv param 3) - with RROC.
2022-11-17 10:54-10:19 Batt swap, a more powerful solar panel may be needed in the future
2022-12-13 10:24-11:54 Site visit to replace low/bad battery and routine mmt 74, dcp battery
11.9v (11.56v under load), replaced, new battery 13.1v, downloaded
