Jordan Hydroelectric Project, P-11437 - Water Quality Report for May - October, 2016
Dear Ms. Higgins:
This letter and attachments report the water quality for the summer of 2016 for the Jordan Hydroelectric Project
(Project), P-11437, at B.E. Jordan Damon the Haw River in Chatham County. 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
temperature on a daily basis were measured and are recorded in the attached table.
Hydropower generation began about January 12, 2012; this completes our fifth 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 of Jordan Dam. 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 twice weekly
thereafter. The thermocouple does not need calibration. The calibration procedures and frequency exceed 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 while generation was occurring. As noted
below during September and October with DWQ's permission, the 24 hour average requirement (DO > 5.0 mg/1)
was exceeded while testing an air blower to increase DO. One low DO value occurred on September 2, but
generation had ceased when the DO decreased below 4.2 mg/l. 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 except
during blower testing.
Measurement Notes
When the turbines were not generating, measurements still were continuously made, but any violations of state
standards are not reported. Such violations are infrequent. Frequently during the summer the DO from the turbines
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.

January 5, 2017
We have tried to increase generation while complying with state standards by installing an air blower system in the
intake of one turbine to increase oxygen concentration. As indicated, we did install the air blower system in late
August and began testing it to maximize oxygen delivery. Regrettably, during the testing in early September we were
unable to meet the 24 hour criteria of averaging 5.0 mg/l; we were able to exceed the minimum level of 4.0 mg/l. We
would never operate below that minimum level without specific approval from NC DWQ.
We discussed this problem with Debra Owen, the DWQ biologist for Jordan Lake and asked her permission to
operate the turbines when the 24 hour average DO was below 5.0 mg/l. See attached email request. She agreed to
allow this variance as long as the minimum of 4.0 mg/l was observed. As shown in the attached data table, during
September the 24 hour average went below 5.0 mg/l on 12 days; there were no variances during October. The lowest
24 hour average that was observed was 4.5 mg/l.
Testing will continue during the low DO season of 2017. We hope we can improve the air injection so there is no 24
hour average below 5 mg/l.
This document is being sent electronically for convenience. Sorry we could not get the chart horizontal scale correct.
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. Please respond with any questions or
approval by late January, so we can file with FERC.
Yours truly,

After Sept. 8 NC D/VQ allowed the 24 hour average On Sept. 2 with generation stopped the downstream
to be below 5.0 mg/l but the minimum had to be DO descended to 3.6 mg/l.
> 4.0 mg/I. A air blower was tested during this
period. With the blower operating only 12 days had a low 24 hour average.

As we discussed on Thursday, September 8, we have allowed the dissolved oxygen (DO) level to go below 5.0 mg/I for the 24-
hour average. This is only being done during this period in September and October while we are testing an air blower system
that is supposed to add oxygen to the water passing through the turbines at Jordan Hydroelectric Project at Jordan Dam on the
Haw River in Chatham County. This air blower system should minimize the need to spill water to keep the downstream DO
above 4.0 mg/I, as required.
I explained the request to let the 24-hour average go below 5.0 mg/I was necessary during the testing because the naturally
occurring DO is sometimes nearly below or below 5.0 mg/I when averaged for 24 hours. The requirement to keep the 24 hour
average above 5 mg/I inhibits testing of the DO system, because the system is trying to keep the DO above 4.0 mg/I, the
instantaneous limit, but it is often unable to also keep the 24 hour average above 5.0 mg/I.
An example is the present time late on Sunday night, the 24 hour average is about 4.7 mg/I, but the instantaneous DO is 5.3
mg/I. During the testing we have done in the last three days the 24 hour average has not been below 4.6 mg/I. Without the
forbearance of being able to reduce the 24 hour average, we would have to stop generating because we would violate the 24
hour requirement even though we are not and have not violated the instantaneous requirement. Even then, some of the time
during the current drought the 24 hour average DO would be below 5 mg/I even with no generation.
You agreed to allow us to temporarily violate this 24 hour requirement to keep generating during the testing period, which is
necessary for the testing to be meaningful. Making the air injection system work presents many challenges, and we are having to
adjust the system during operation at low DO to make its operation effective.
No Change in or Violation of Instantaneous DO Requirement
This operation at reduced DO for the 24 hour average is not affecting the requirement to keep instantaneous DO above 4.0 mg/I;
this requirement has never been violated during our 5 summers of operation except when sensors malfunctioned. We normally
trip the turbines when the DO goes below 4.3 mg/I, because after the trip the DO decreases as turbine flow decreases before the
spill gates can open sufficiently to restore the flow amount prior to the trip. Opening the spill gates fully takes more than a few
minutes.
I hope this explains our need for this forbearance in the 24 hour DO requirement. Please call with any questions.
When we provide our annual report to Karen Higgins in January, we will explain the discrepancy in the 24 hour requirement and
actual measurements.
