Jordan Hydroelectric Project, P-11437 – Water Quality Report for May – October, 2014
Dear Ms. Higgins:
This letter and attachments report the water quality for the summer of 2014 for the Jordan Hydroelectric Project
(Project), P-11437, at B.E. Jordan Dam on the Haw River. This information is filed for compliance with the Water
Quality Certificate (Certificate), issued to the licensee (Jordan Hydroelectric Limited Partnership or JHLP) by NC DWQ
on October 4, 2006, and with the license P-11437 issued by Federal Energy Regulatory Commission. As required in
item 3 in the Certificate, water quality was measured below Jordan Dam in the Haw River from May 1 through October
31, 2013. Both average and minimum dissolved oxygen (DO) and average temperature on a daily basis were measured
and are recorded in the attached table.
Hydropower generation began about January 12, 2012; this is our third year of generation. Measurements were made in
the Haw River at a depth of about 2 feet and about 100 feet downstream of the stilling basin for the tunnel discharge.
The probes are secured in pipes on a concrete fishing pier on the bank of the river. Measurements were recorded every
half hour. An optical probe was used (Model RDO by InSitu) to measure DO. A thermocouple was used to measure
temperature. The optical probe was calibrated initially and weekly thereafter. The thermocouple does not need
calibration. The calibration procedures and frequency are compliant with the manufacturer’s specifications.
Measurements of DO and temperature were made continuously during the six month period and recorded by the plant’s
computer and control system.
As shown in the attached table and graph, the daily average DO, minimum DO and average temperature are reported for
each day. DO is measured in milligrams per liter and temperature in degrees Fahrenheit. There were no violations of
North Carolina’s water quality standards during the measurement period. All valid DO measurements were within the

state standards, equal to or exceeding 4.0 mg/l instantaneously and averaging at or above 5.0 mg/l in 24 hours.

Measurement Notes
There are two circumstances that affected the collection of water quality data in 2014. They are fouling of the probe and
equipment malfunction causing the probe to cease measuring. Fouling of the probe is the most common reason
measurements are not made. When the turbines were not generating, measurements were usually made, but any
violations of state standards are not reported. Such violations are rare. Other than these faults, there were no problems
with the measurements, and all measurements were valid and are reported. Frequently during the summer the DO from
the turbine is too low and water must be diverted from the turbine and spilled through two water quality and one service

gates in the intake tower.The turbines are not operated when the DO descends to near 4.0 mg/l. The turbine control
system stops generation and opens a gate to spill water until an operator restores generation or establishes flow bypassing

the turbine.

From late May 19 until midday May 20 the probe was out of service; during periods of measurement the average DO
was 7 mg/l and the minimum 4.5 mg/l; after cleaning the DO rose sharply. On May 23 the probe was found to be fouled
by considerable slime on the membrane. It was cleaned and put into service after a few hours. The measured DO
immediately rose from 4.1 to 7.6 mg/l. After that incident calibrations were made twice weekly and usually will be that
frequent in the future.
The probe was similarly out of service during much of June 14 through 23. There was no generation during June 14
until June 20, so probe readings were not recorded as violations. Oscillations in the probe reading caused unusable
readings from June 21 through 23, when the problem was fixed. There was no generation from July 21 through 29
including the low DO reading on July 21. Fouling of the probe caused the probe to be removed and cleaned on
September 19 and October 3.
These incidents when measurements were not made or were not reliable because of probe fouling or malfunction are not
included in the summary information at the bottom of the table. Notes on the table indicate their occurrence.
Low DO in the tailrace continues to cause us to reduce or cease operation to avoid violations. The critical low DO
periods seem to occur at low flow. We have tried several solutions in the past to increase DO, but none have been
successful yet. We plan to try other methods.

This document is being sent electronically for convenience. A paper copy will be sent to NC DWQ for official use if
requested. Should anyone from your office wish to visit the plant and observe data collection, please call or contact us
via email. Please contact us with any questions.
We must send a copy of your comments to FERC by the end of January. I attached a copy of your comments from
January 2013; they were sufficient for what we must file with FERC.
Yours truly,
